Abstract Objective: To evaluate the efficacy of [alpha]2-adrenergic agonist (AA) brimonidine and topical carbonic anhydrase inhibitors (CAIs) dorzolamide and brinzolamide in reducing intraocular pressure (IOP) when used as adjunctive therapy to [beta]-blockers (BBs) or prostaglandin analogs (PGAs). Research design and methods: Pertinent publications were identified through systematic searches of PubMed, EMBASE, and the Cochrane Controlled Trials Register. Randomized controlled trials comparing AA with CAIs in patients with primary open-angle glaucoma (POAG) or ocular hypertension (OHT) who had inadequate IOP control with monotherapy of a BB or PGA. The weighted mean differences (WMD) of IOP-lowering efficacy were calculated by performing meta-analysis. Main outcome measures: The main efficacy measures were the reduction from baseline to end of treatment in IOP at peak, trough, and diurnal curve. Results: Eleven published randomized clinical trials involving 1493 patients were included in the meta-analysis. As adjunctive therapy, the IOP reduction was greater in the brimonidine group than in the CAI group at peak (WMD: 0.99 mmHg [95% confidence interval, 0.45 to 1.53]) and diurnal curve (WMD: 0.62 mmHg [0.07 to 1.18]). As adjunctive therapy to BBs, brimonidine was more effective than CAIs in reducing IOP at peak (WMD: 0.85 mmHg [0.42 to 1.29]) and trough (WMD: 0.47 mmHg [0.12 to 0.83]). As adjunctive therapy to PGAs, brimonidine resulted greater reduction in peak IOP than CAIs (WMD: 1.04 mmHg [0.08 to 2.00]). Conclusions: Brimonidine provides greater IOP-lowering efficacy than topical carbonic anhydrase inhibitors as adjunctive therapy to BBs or PGAs. [ABSTRACT FROM AUTHOR]

Thermokarst landslide (TL) activity in the Qinghai-Tibet Plateau (QTP) is intensifying due to climate warming-induced permafrost degradation. However, the mechanisms driving landslide formation and evolution remain poorly understood. This study investigates the spatial distribution, annual frequency, and monthly dynamics of TLs along the Qinghai-Tibet engineering corridor (QTEC), in conjunction with in-situ temperature and rainfall observations, to elucidate the interplay between warming, permafrost degradation, and landslide activity. Through the analysis of high-resolution satellite imagery and field surveys, we identified 1298 landslides along the QTEC between 2016 and 2022, with an additional 386 landslides recorded in a typical landslide-prone sub-area. In 2016, 621 new active-layer detachments (ALDs) were identified, 1.3 times the total historical record. This surge aligned with unprecedented mean annual and August temperatures. The ALDs emerged primarily between late August and early September, coinciding with maximum thaw depth. From 2016 to 2022, 97.8 % of these ALDs evolved into retrogressive thaw slumps (RTSs), identified as active landslides. Landslides typically occur in alpine meadows at moderate altitudes and on gentle northward slopes. The thick ice layer near the permafrost table serves as the material basis for ALD occurrence. Abnormally high temperature significantly increased the active layer thickness (ALT), resulting in melting of the ice layer and formation of a thawed interlayer, which was the direct causing factor for ALD. By altering the local material, micro-topography, and thermal conditions, ALD activity significantly increases RTS susceptibility. Understanding the mechanisms of ALD formation and evolution into RTS provides a theoretical foundation for infrastructure development and disaster mitigation in extreme environments., Competing Interests: Declaration of competing interest The authors declare no conflict of interest., (Copyright © 2024 Elsevier B.V.

A high-fat diet (HFD) contributes to the pathogenesis of various inflammatory and metabolic diseases. Previous research confirms that under HFD conditions, the extraorbital lacrimal glands (ELGs) can be impaired, with significant infiltration of pro-inflammatory macrophages (Mps). However, the relationship between HFD and Mps polarization in the ELGs remains unexplored. We first identified and validated the differential expression of PPAR-γ in murine ELGs fed ND and HFD through RNA sequencing. Tear secretion was measured using the Schirmer test. Lipid droplet deposition within the ELGs was observed through Oil Red O staining and transmission electron microscopy. Mps phenotypes were determined through quantitative RT-PCR, immunofluorescence, and flow cytometric analysis. An in vitro high-fat culture system for Mps was established using palmitic acid (PA), with supernatants collected for co-culture with lacrimal gland acinar cells. Gene expression was determined through ELISA, immunofluorescence, immunohistochemistry, quantitative RT-PCR, and Western blot analysis. Pioglitazone reduced M1-predominant infiltration induced by HFD by increasing PPAR-γ levels in ELGs, thereby alleviating lipid deposition and enhancing tear secretion. In vitro tests indicated that PPAR-γ agonist shifted Mps from M1-predominant to M2-predominant phenotype in PA-induced Mps, reducing lipid synthesis in LGACs and promoting lipid catabolism, thus alleviating lipid metabolic disorders within ELGs. Conversely, the PPAR-γ antagonist induced opposite effects. In summary, the lacrimal gland is highly sensitive to high-fat and lipid metabolic disorders. Downregulation of PPAR-γ expression in ELGs induces Mps polarization toward predominantly M1 phenotype, leading to lipid metabolic disorder and inflammatory responses via the NF-κb/ERK/JNK/P38 pathway., Competing Interests: Conflict of interest The authors declare that they have no conflicts of interest with the contents of this article., (Copyright © 2024 The Authors.

The group standard Pharmacovigilance guidelines for clinical application of Chinese patent medicines for mucosal administration was released on January 16, 2024, on the national group standards information platform by the Institute of Basic Research in Clinical Medicine of China Academy of Chinese Medical Sciences and School and Hospital of Stomatology of Peking University, under the centralized management by the China Association of Chinese Medicine. The standard number is T/CACM 1563.6-2024. It aims to propose key elements and specify technical methods for safety monitoring and reporting, signal identification, risk assessment, and risk control based on the Drug administration law of the People's Republic of China(revised in 2019), which establishes normative pharmacovigilance guideline of Chinese patent medicine for mucosal administration that is in line with the characteristics of traditional Chinese Medicine(TCM) based on the pharmacovigilance content for clinical application of Chinese patent medicine for mucosal administration. The group standard has been discussed by internal and external experts through multiple rounds of consultation. It serves as a guiding document for stakeholders involved in pharmacovigilance activities, including pharmaceutical license holders, drug manufacturers, medical institutions, research institutes, and pharmaceutical trading enterprises.

Oral Chinese patent medicine is the essence of effective prescriptions created and summarized by Chinese medical scientists through thousands of years of medical practice. It is portable and convenient, with an obvious curative effect and other characteristics. However, at present, oral Chinese patent medicine is rich in dosage forms, various in types, complex in mechanism of action, and broad in clinical positioning. In clinical application, there are often cases of drug use without reference to instructions,repeated drug use, and prolonged drug use, which highlights safety problems such as adverse reactions and hepatorenal toxicity. Oral Chinese patent medicine pharmacovigilance is facing challenges. World Health Organization(WHO) has issued the WHO guidelines on safety monitoring of herbal medicines in pharmacovigilance systems, and International Council for Harmonisation of Technical Requirements for Pharmaceuticals for Human Use(ICH) has issued the ICH E2 pharmacovigilance guidelines. The United States has issued the Pharmacovigilance management standards and pharmacoepidemiological assessment guidelines, and the European Union has issued the Guidelines on good pharmacovigilance practices. Japan, South Korea, and other countries in the Asia Pacific region have established their own pharmacovigilance systems, but currently, there are no pharmacovigilance guidelines related to oral Chinese patent medicine in China. Therefore, experts from many disciplines and fields in China were invited to jointly develop the Pharmacovigilance guidelines for clinical application of oral Chinese patent medicines, which aims to develop pharmacovigilance guidelines for clinical application that are consistent with China's national conditions and highlight the characteristics of oral Chinese patent medicine, and provide guidance for clinically safe and rational drug application in medical institutions.

Drug administration law of the People's Republic of China(2019 revised edition), which came into effect on December 1, 2019, proposed that " the state shall establish a pharmacovigilance system". Pharmacovigilance work of Chinese patent medicines is more difficult, and it is necessary to carry out Pharmacovigilance activities that are in line with the characteristics of Chinese patent medicines. Pharmacovigilance guidelines of Chinese patent medicines(T/CACM 1563. 1-2024), based on the principles of Drug Administration Law of the People's Republic of China(2019 revised edition) and Pharmacovigilance quality management standards(No. 65 of 2021) of the National Medical Products Administration, draws on the EU Pharmacovigilance regulation and the secondary guidelines of International Council for Harmonization of Technical Requirements for Pharmaceuticals for Human Use(ICH), and it is drafted in accordance with the provisions of Guidelines for standardization work part 1: structure and drafting rules of standardization documents(GB/T1. 1-2020) based on the characteristics of Chinese patent medicines. It serves as a general document for a series of pharmacovigilance guidelines of Chinese patent medicines, such as Guidelines for construction of traditional Chinese medicine pharmacovigilance system in medical institutions(T/CACM 1563. 2-2024), Pharmacovigilance guidelines for clinical application of oral Chinese patent medicines(T/CACM 1563. 3-2024), Pharmacovigilance guidelines for clinical application of traditional Chinese medicine injections(T/CACM 1563. 4-2024), Pharmacovigilance guidelines for clinical application of Chinese patent medicines for external use(T/CACM 1563. 5-2024), and Pharmacovigilance guidelines for clinical application of Chinese patent medicines for mucosal administration(T/CACM 1563. 6-2024), including four major elements of pharmacovigilance monitoring and reporting of Chinese patent medicines, signal identification, risk evaluation, and risk control, as well as pharmacovigilance activities for Chinese patent medicines, ensuring the safety of public drug use.

The group standard Guidelines for construction of traditional Chinese medicine(TCM) pharmacovigilance system in medical institutions, managed by Chinese Association of Chinese Medicine and led by the Institute of Basic Research in Clinical Medicine,China Academy of Chinese Medical Sciences and Dongfang Hospital of Beijing University of Chinese Medicine, was announced on National Group Standard Information Platform on January 16, 2024, with the standard number T/CACM 1563. 2-2024. According to EU pharmacovigilance regulations and the second-level guidance principles of International Council for Harmonization of Technical Requirements for Pharmaceuticals for Human Use(ICH), the unique characteristics of TCM were fully considered, and the relevant systems and procedures for constructing TCM pharmacovigilance systems in medical institutions were clearly defined. This included establishing TCM pharmacovigilance information platforms, arranging staff, formulating various regulations, and monitoring adverse reactions of TCM(including TCM decoction pieces, granules, Chinese patent medicines, in-hospital preparations, and pre-marketed Chinese patent medicines). It aimed to develop a TCM pharmacovigilance system in medical institutions that was tailored to the characteristics of TCM. The system could be appropriately adjusted according to the scope of practice and actual circumstances of medical institutions at different levels. This will enhance the implementation of TCM pharmacovigilance work and safeguard medication safety. The group standard underwent multiple rounds of consultations with internal and external experts and has ultimately evolved into a guiding document applicable to medical institutions and related entities engaged in pharmacovigilance activities.

Objective: To explore the outcome of different treatment strategies in patients with pancreatic cancer with synchronous liver metastasis (sLMPC). Methods: A retrospective analysis of the clinical data and treatment results of 37 patients with sLMPC treated in China-Japan Friendship Hospital was performed from April 2017 to December 2022. A total of 23 males and 14 females were included,with an age( M (IQR)) of 61 (10) years (range: 45 to 74 years). Systemic chemotherapy was carried out after pathological diagnosis. The initial chemotherapy strategy included modified-Folfirinox, albumin paclitaxel combined with Gemcitabine, and Docetaxel+Cisplatin+Fluorouracil or Gemcitabine with S1. The possibility of surgical resection (reaching the standards of surgical intervention) was determined after systemic treatment,and the chemotherapy strategy was changed in the cases of failed initial chemotherapy plans. The Kaplan-Meier method was used to estimate the overall survival time and rate,while Log-rank and Gehan-Breslow-Wilcoxon tests were used to compare the differences of survival curves. Results: The median follow-up time for the 37 sLMPC patients was 39 months,and the median overall survival time was 13 months (range:2 to 64 months) with overall survival rates of 1-,3-,and 5-year of 59.5%,14.7%,and 14.7%,respectively. Of the 37 patients,97.3%(36/37) initially received systemic chemotherapy, 29 completed more than four cycles,resulting in a disease control rate of 69.4% (partial response in 15 cases,stable disease in 10 cases,and progressive disease in 4 cases). In the 24 patients initially planned for conversion surgery,the successful conversion rate was 54.2% (13/24). Among the 13 successfully converted patients,9 underwent surgery and their treatment outcomes were significantly better than those (4 patients) of those who did not undergo surgery (median survival time not reached vs. 13 months, P <0.05). Regarding the 9 patients whose conversion was unsuccessful, no significant differences were observed in median survival time between the surgical group (4 cases) and the non-surgical group (5 cases) ( P >0.05). In the allowed-surgery group( n =13),the decreased in pre-surgical CA19-9 levels and the regression of liver metastases were more significant in the successful conversion sub-group than in the ineffective conversion sub-group;however, no significant differences were observed in the changes in primary lesion between the two groups. Conclusion: For highly selective patients with sLMPC who achieve partial response after receiving effective systemic treatment,the adoption of an aggressive surgical treatment strategy can significantly improve survival time;however, surgery dose not provide such survival benefits in patients who do not achieve partial response after systemic chemotherapy.

Retinoblastoma (RB) and uveal melanoma (UM) are the most common primary intraocular tumors in children and adults, respectively. Despite continued increases in the likelihood of salvaging the eyeball due to advancements in local tumor control, prognosis remains poor once metastasis has occurred. Traditional sequencing technology obtains averaged information from pooled clusters of diverse cells. In contrast, single-cell sequencing (SCS) allows for investigations of tumor biology at the resolution of the individual cell, providing insights into tumor heterogeneity, microenvironmental properties, and cellular genomic mutations. SCS is a powerful tool that can help identify new biomarkers for diagnosis and targeted therapy, which may in turn greatly improve tumor management. In this review, we focus on the application of SCS for evaluating heterogeneity, microenvironmental characteristics, and drug resistance in patients with RB and UM., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 He, Mou, Yang, Huang, Shen, Zhang and Wei.)

Background: Hyperlipidemia is a common complication after liver transplantation (LT) and develops mostly in the early posttransplant period. Recently, some studies have reported a positive correlation between hyperlipidemia and favorable prognosis in patients with hepatocellular carcinoma (HCC) undergoing hepatectomy. This study aimed to evaluate the possibility of predicting prognosis in HCC patients receiving LT by early posttransplant dyslipidemia., Methods: From January 2015 to December 2017, a total of 806 HCC patients from China Liver Transplant Registry database were retrospectively enrolled. The prognostic relevance of early posttransplant hypertriglyceridemia or hypercholesterolemia was examined using survival analysis, and subgroup analysis was implemented based on LT criteria., Results: Early posttransplant hypercholesterolemia (EPHC) was independently inversely associated with the risk of recurrence [hazard ratio (HR) = 0.630; P = 0.022], but was not significantly correlated with the mortality. However, early posttransplant hypertriglyceridemia was not related to prognosis. Intriguingly, with further classification, we found that borderline EPHC (B-EPHC), instead of significant EPHC, was a predictor of lower risk for both recurrence (HR = 0.504; P = 0.006) and mortality (HR = 0.511; P = 0.023). Compared with non-EPHC patients, B-EPHC patients achieved significantly superior 1-year and 3-year tumor-free survival (89.6% and 83.7% vs. 83.8% and 72.7% respectively; P = 0.023), and 1-year and 3-year overall survival (95.8% and 84.8% vs. 94.6% and 77.6% respectively; P = 0.039). In the subgroup analysis, B-EPHC remained an independent predictor of better prognosis in patients beyond Milan criteria and those within Hangzhou criteria; whereas there was no significant relationship between B-EPHC and prognosis in patients within Milan criteria and those beyond Hangzhou criteria. More interestingly, patients beyond Milan criteria but within Hangzhou criteria were identified as the crucial subpopulation who benefited from B-EPHC (recurrence HR = 0.306, P = 0.011; mortality HR = 0.325, P = 0.031)., Conclusions: B-EPHC could assist transplant teams in dynamically evaluating prognosis after LT for HCC as a postoperative non-oncological biomarker, especially in patients beyond Milan criteria but within Hangzhou criteria., (Copyright © 2022.

Background: Non-cutaneous squamous cell carcinoma (ncSCC) of the orbital region is very rare. Thus, its epidemiological characteristics and prognosis are poorly understood. The aim of the study was to assess the epidemiological characteristics and survival outcomes of ncSCC of the orbital region., Methods: Incidence and demographic data on ncSCC of the orbital region were extracted from the Surveillance, Epidemiology, and End Results (SEER) database and analyzed. The chi-square test was used to calculate the differences between groups. Univariate and multivariate Cox regression analyses were performed to determine the independent prognostic factors for disease-specific survival (DSS) and overall survival (OS)., Results: The overall incidence of ncSCC in the orbital region from 1975 to 2019 was 0.68/1,000,000, and the incidence showed an increasing trend during this period. A total of 1,265 patients with ncSCC of the orbital region (mean age, 65.3 years) were identified in the SEER database. Of these, 65.1% were aged ≥60 years, 87.4% were White, and 73.5% were male. The conjunctiva (74.5%) was the most common primary site, followed by the orbit (12.1%), lacrimal apparatus (10.8%), and overlapping lesion of the eye and adnexa (2.7%). Multivariate Cox regression analysis revealed that age, primary site, SEER summary stage, and surgery were independent prognostic factors for DSS, whereas age, sex, marital status, primary site, SEER summary stage, and surgery were independent prognostic factors for OS., Conclusions: The incidence of ncSCC in the orbital region has increased over the past 40 years. It usually affects White people, men, and people aged ≥60 years, and its most common site is the conjunctiva. Orbital SCC has worse survival outcomes than SCC of other sites in the orbital region. Surgery is the independent protective treatment for ncSCC of the orbital region., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 He, Mou and Wei.)

Graves' ophthalmopathy (GO) is an inflammatory autoimmune disease that affects the eyes. It can significantly alter the quality of life in patients because of its distinctive pathological appearance and the effect on vision. To date, the exact pathological mechanism of GO has not been explicitly discovered. However, several studies have associated autophagy with this disease. Autophagy is a catabolic process that helps maintain homeostasis in all organisms by protecting the cells and tissues from various endogenous and exogenous stress factors. Based on our results, patients affected with GO have comparatively elevated levels of autophagy, which critically affects the pathological mechanism of the GO. In this review, we have summarized the autophagy mechanism in the pathogenesis of GO., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2023 Chen, Gao, Liu, Shen, Diao, Yang and Wei.)

The structure of orbit is complex and its function is critical. Quantitative determination of orbital volume is valuable to diagnosis and treatment of orbital diseases, but a standardized and reproducible orbital volume measurement method is still not available. Recently, with the development of three-dimensional reconstruction, many researchers gradually convert their insight into three-dimensional orbital measurement. This paper reviews the common methods of three-dimensional orbital measurement used by investigators, including some innovative ideas, and their clinical applications in order to make a comprehensive overview of the current orbital measurement technology, explore the possible improvement direction, and better serve the clinical.

Background: Primary intraocular lymphoma (PIOL) is a rare malignancy with a poor prognosis, but its optimal therapy remains unclear. Herein, we aimed to analyze the epidemiology and survival outcomes of PIOL patients based on a population-based cancer registry in the United States., Methods: Patients diagnosed with PIOL between 1992 and 2018 were identified from the Surveillance Epidemiology and End Results program. The patients were divided into two groups: those aged < 60 years and ≥ 60 years. We used the chi-squared test to analyze the differences between the two groups. Descriptive analyses were performed to analyze epidemiological characteristics and treatment. The likely prognostic factors were analyzed by Kaplan-Meier curves and Cox proportional hazards models., Results: The overall incidence of PIOL was 0.23/1,000,000, which was steadily increasing from 1992 to 2018, with an annual percentage change of 2.35. In total, 326 patients (mean age, 66.1 years) with PIOL were included in this study, 72.1% were aged ≥ 60 years, 84.4% were White, and 60.4% were female. The most common pathological type was diffuse large B-cell lymphoma (DLBCL), but in patients aged < 60 years, extranodal marginal zone lymphoma of mucosa-associated lymphoid tissue was the most common. The disease-specific survival rates were 74.2% and 61.5% 5 and 10 years after diagnosis, respectively. Survival analysis found that surgery, radiation, and chemotherapy did not lead to better prognosis., Conclusions: PIOL is a rare disease with poor prognosis, and its incidence has been increasing for nearly 30 years. It usually affects people aged ≥ 60 years, and DLBCL is the most common pathological type of PIOL. Patients aged < 60 years and with non-DLBCL type have improved survival. Survival of PIOL has improved in recent years., (© 2022. The Author(s).)

Objective: Primary orbital lymphoma (POL) accounts for an essential part of adult orbital malignancies. Nevertheless, it remains a relatively rare lymphoid malignancy, accounting for <1% of all non-Hodgkin's lymphoma (NHL) cases. Orbital diffuse large B-cell lymphoma (DLBCL) is one of the most prevalent subtypes of POL that confers the worst outcomes. The prognostic determinants of orbital DLBCL remain unknown. Therefore, a retrospective analysis was conducted by investigating the Surveillance, Epidemiology, and End Results (SEER) database for independent predictive factors for the prognosis of orbital DLBCL., Materials and Methods: Using the SEER program, we acquired patient data including demographics, clinical characteristics, and treatment strategies. Our cohort included cases of primary orbital DLBCL diagnosed from 2000 to 2017. We conducted Kaplan-Meier analyses to visualize the overall survival (OS) and cause-specific survival (CSS). The Cox proportional hazard regression models were applied to assess the effects of these prognostic factors on OS and CSS., Results: The present cohort included 332 patients with orbital DLBCL. Age was the most impacted variable by orbital DLBCL. Three independent prognostic variables of orbital DLBCL were identified on diagnosis: advanced age, no radiation treatment, and late-stage (Stage IV). Moreover, patients who underwent chemotherapy demonstrated a greater OS when compared with those who did not. In orbital DLBCL, being unmarried was also a poor prognostic factor., Conclusion: The current study is the largest population-based case series of orbital DLBCL. The age at the time of diagnosis, marital status, absence of chemotherapy or radiotherapy, and tumor stage were all found to be correlated with worse prognosis., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2022 Chen, Yue, Chen, Tong, Yang and Wei.)

A 19-year-old patient with bilateral eyelid swelling for more than 2 years visited the Department of Ophthalmology. Physical examination disclosed a moderately active mass in the upper eyelid and lacrimal gland area in each eye. Orbital MRI showed that the lacrimal glands were significantly enlarged and moved forward in both eyes, and the enlargement was more severe in the left eye. The patient was admitted twice to the hospital for removal of orbital masses and was diagnosed as orbital Rosai-Dorfman disease by histopathological examination. During three months of follow-up, the patient was in good physical condition, and there was no tumor recurrence.

Objective: To delineate the onset and recurrence characteristics of noncardiogenic ischemic stroke patients in China., Methods: A prospective, multicenter and registry study was carried out in 2,558 patients at 7 representative clinical sub-centers during November 3, 2016 to February 17, 2019. A questionnaire was used to collect information of patients regarding CM syndromes and constitutions and associated risk factors. Additionally, stroke recurrence was defined as a primary outcome indicator., Results: A total of 327 (12.78 %) patients endured recurrence events, 1,681 (65.72%) were men, and the average age was 63.33 ± 9.45 years. Totally 1,741 (68.06%) patients suffered first-ever ischemic stroke, 1,772 (69.27%) patients reported to have hypertension, and 1,640 (64.11%) of them reported dyslipidemia, 1,595 (62.35%) patients exhibited small-artery occlusion by The Trial of Org 10172 in Acute Stroke Treatment (TOAST) classification. Specifically, 1,271 (49.69%) patients were considered as qi-deficient constitution, and 1,227 (47.97%) patients were determined as stagnant blood constitution. There were 1,303 (50.94%) patients diagnosed as blood stasis syndrome, 1,280 (50.04%) patients exhibited phlegm and dampness syndrome and 1,012 (39.56%) patients demonstrated qi deficiency syndrome. And 1,033 (40.38%) patients declared intracranial artery stenosis, and 478 (18.69%) patients reported carotid artery stenosis. The plaque in 1,508 (41.36%) patients were of mixed. Particularly, 41.09% of them demonstrated abnormal levels of glycated hemoglobin levels., Conclusions: Recurrence in minor and small-artery stroke cannot be ignored. Hypertension, dyslipidemia, abnormal HbA1c, intracranial artery stenosis and carotid plaque were more common in stroke patients. Particularly, phlegm-dampness and blood stasis syndromes, as well as qi deficiency and blood stasis constitutions, were still the main manifestations of stroke.

To evaluate the pharmacoeconomic value of Qidong Yixin Oral Liquid in the treatment of viral myocarditis(Qi-Yin deficiency syndrome) by supplementing Qi, nourishing the heart, calming the mind, and relieving palpitation, the present study performed the Meta-analysis based on the published papers on Qidong Yixin Oral Liquid by AMSTAR and carried out pharmacoeconomic evaluation using TreeAge Pro by the cost-effectiveness analysis. The results showed that the quality of the included papers was good. After four weeks of treatment, Qidong Yixin Oral Liquid combined with the conventional treatment regimen was superior to the conventional treatment in improving creatine kinase isoenzyme, and the difference was statistically significant. Furthermore, the treatment cost was also higher than that of conventional treatment, with an incremental cost-effectiveness ratio of CNY 95.89, accounting for 0.30% of per capita disposable income. The results of sensitivity analysis showed that the research results were robust. Therefore, based on the assumption that the per capita disposable income in 2020 was the threshold of patients&apos; willingness to pay, it is more economical for patients with viral myocarditis to use Qidong Yixin Oral Liquid combined with conventional secondary prevention regimen than conventio-nal secondary prevention regimen alone. The economic evaluation of Qidong Yixin Oral Liquid in the treatment of viral myocarditis will help physicians and patients choose optimal treatment options, improve rational clinical medication, and provide references for the efficient allocation and utilization of medical resources in China.

Aim: To explore the effect of miR-184 and miR-205 on the proliferation and metastasis of conjunctival mucosa associated lymphoid tissue (MALT) lymphoma., Methods: Tissue of tumor and adjacent normal control from 5 patients with conjunctival MALT was included. RPMI8226 cell line was selected to verify the effect of miRNAs in B cells. The function of microRNA on the RPMI8226 cell apoptosis, migration and invasion was evaluated by apoptosis assay and Transwell assay. The mRNA and protein expression were examined by quantitative RT-PCR and Western blotting. The effect of microRNA on regulation of downstream gene expression was evaluated by luciferase report assay., Results: A decreased level of miR-184 and miR-205 was observed in MALT lymphoma tissue. Exogenous miR-184 and miR-205 analogues promoted apoptosis, and inhibited the survival, migration, and invasion of RPMI8226 cells. miR-184 and miR-205 inhibitor reversed the process. The RNA and protein level of RasL10B and TNFAIP8 were downregulated in MALT lymphoma tissue. The exogenous of miR-184 and miR-205 promoted the expression of RasL10B and TNFAIP8. Meanwhile, inhibition of miR-184 and miR-205 repressed the expression of target gene, RasL10B and TNFAIP8., Conclusion: miR-184 and miR-205 suppresses the tumorigenesis of conjunctival MALT lymphoma through regulating RasL10B and TNFAIP8., (International Journal of Ophthalmology Press.)

This study evaluated the safety, effectiveness, economy, innovation, suitability, accessibility, and characteristics of traditional Chinese medicine of Wenxin Granules in the treatment of arrhythmia(ventricular premature beat and atrial premature beat) with deficiency of Qi and Yin. The multi-criteria decision analysis(MCDA) model was adopted, and the criterion layer and index layer were weighted by experts. CSC v2.0 was used for clinical comprehensive evaluation. This study embodies the clinical value of Wenxin Granules, promotes its safe, effective and rational use, and provides a basis for national medical decision-making. The multi-source evidence shows that the major adverse reaction of Wenxin Granules is gastrointestinal damage. According to the available studies, Wenxin Granules has controllable risk and thus is rated as grade B in terms of safety. The systematic evaluation of effectiveness shows that compared with antiarrhythmic western medicine, Wenxin Granules demonstrates improved clinical efficacy and electrocardiogram efficacy, which is supported by high-quality evidence, and thus the effectiveness of Wenxin Granules is evaluated as grade A. Economic research shows that Wenxin Granules is more economical than antiarrhythmic western medicine, which is supported by sufficient evidence and clear results, and thus the economy of this preparation is rated as grade B. The indications and contraindications of Wenxin Granules are clear and detailed to different types of arrhythmia, which, together with the precise positioning and prominent clinical innovation and industrial innovation, rates it as grade A in terms of innovation. The suitability of drug storage, prescription circulation, dosage form and course of treatment basically meet the clinical medication needs of doctors and patients, and thus the suitability of Wenxin Granules is evaluated as grade B. Because of the few restrictions and the sustainable resources of medicinal materials, the accessibility of Wenxin Granules is evaluated as grade A. The prescription compatibility focuses on the pathogenesis characteristics of deficiency of Qi and Yin, and there are more than 3 000 cases studied. Therefore, the characteristics of traditional Chinese medicine of Wenxin Granules are evaluated as grade B. Based on the evidence from all the above dimensions, Wenxin Granules has the clinical comprehensive value of class A and prominent characteristics of traditional Chinese medicine. It is suggested to include Wenxin Granules into the policy results related to basic clinical medication management according to the procedure.

The clinical comprehensive evaluation of drugs is an important basis for the return of clinical value, decision-making of medical and health authorities, and allocation of medical resources. In July 2021, the National Health Commission issued the Guidelines for the Management of Clinical Comprehensive Evaluation of Drugs(trial version 2021), which required the evaluation to be implemented from the six dimensions(safety, effectiveness, economy, innovation, suitability, and accessibility), and made detailed arrangements for the clinical comprehensive evaluation of drugs. As Chinese patent medicine differs from chemical medicines in terms of effective components and action modes, the clinical comprehensive evaluation of Chinese patent medicine should highlight the characteristics and advantages of traditional Chinese medicine(TCM) on the basis of general requirements of comprehensive clinical evaluation of drugs. At present, in the clinical comprehensive evaluation of Chinese patent medicine, unified report standards have not yet been generated, resulting in the uneven quality of existing reports. To standardize the clinical comprehensive evaluation report of Chinese patent medicine and improve its quality, the editorial team, based on the relevant policy documents of clinical comprehensive evaluation of drugs, formulated the clinical comprehensive evaluation report standards for Chinese patent medicine in combination with the previous practice and expert opinions. The report standards, containing seven sections with 15 items determined, focus on data source, evaluation content, evidence synthesis, quality control, and evaluation results supported with detailed interpretations to help researchers better understand and apply the report standards for clinical comprehensive evaluation of Chinese patent medicine, improve the report quality, and provide references for the decision-making by the national medical management authorities.

This paper discusses the rational use of traditional Chinese medicine based on chemical composition, body state and biological effect. The essence and connotations of traditional Chinese medicine are explained by modern scientific theory and technical means, and the mechanism of traditional Chinese medicine in the treatment of diseases is defined in modern medicine language, which is conducive to promoting rational and safe clinical use of drugs. Based on the chemical composition of traditional Chinese medicine,the selected genuine medicinal materials were collected and processed in a standardized way, and then used in the combination with other traditional Chinese medicines, with the aim to improve the efficacy of traditional Chinese medicine in clinical indications, increase the advantages, eliminate the disadvantages, and adapt to flexible and safe clinical drug demands. Based on the body state elements, clinical diagnosis and treatment shall be patient-centered, and doctors shall distinguish the differences of pathogenesis, symptoms and diseases, and consider the drug contraindications of special groups. According to the &quot; dose-effect-toxicity&quot; relationship, doctors shall select the appropriate dosage form, control the drug dosage, balance the benefits and risks of drugs, and carry out appropriate medical treatment. Based on the biological effect elements and the regulatory mechanism of traditional Chinese medicine on the target and pathway of disease, traditional Chinese medicine shall strengthen the precise positioning, provide accurate treatment; evaluate the safety of traditional Chinese medicine combination, explore the adverse reaction mechanism, strengthen the clinical safety monitoring of traditional Chinese medicine, and guide the clinical rational use of drugs, in the expectation of ensuring the safe use of traditional Chinese medicine and maximize the clinical efficacy of traditional Chinese medicine.

Background: Nonalcoholic fatty liver disease and its advanced stage, nonalcoholic steatohepatitis (NASH), are the major cause of hepatocellular carcinoma (HCC) and other end-stage liver disease. However, the potential mechanism and therapeutic strategies have not been clarified. This study aimed to identify potential roles of miRNA/mRNA axis in the pathogenesis and drug combinations in the treatment of NASH., Methods: Microarray GSE59045 and GSE48452 were downloaded from the Gene Expression Omnibus and analyzed using R. Then we obtained differentially expressed genes (DE-genes). DAVID database was used for Gene Ontology (GO) analysis and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment pathway analysis. Protein-protein interaction (PPI) networks were used for the identification of hub genes. We found upstream regulators of hub genes using miRTarBase. The expression and correlation of key miRNA and its targets were detected by qPCR. Drug Pair Seeker was employed to predict drug combinations against NASH. The expression of miRNA and hub genes in HCC was identified in the Cancer Genome Atlas database and Human Protein Atlas database., Results: Ninety-four DE-genes were accessed. GO and KEGG analysis showed that these predicted genes were linked to lipid metabolism. Eleven genes were identified as hub genes in PPI networks, and they were highly expressed in cells with vigorous lipid metabolism. hsa-miR-335-5p was the upstream regulator of 9 genes in the 11 hub genes, and it was identified as a key miRNA. The hub genes were highly expressed in NASH models, while hsa-miR-335-5p was lowly expressed. The correlation of miRNA-mRNA was established by qPCR. Functional verification indicated that hsa-miR-335-5p had inhibitory effect on the development of NASH. Finally, drug combinations were predicted and the expression of miRNA and hub genes in HCC was identified., Conclusions: In the study, potential miRNA-mRNA pathways related to NASH were identified. Targeting these pathways may be novel strategies against NASH., (Copyright © 2021. Published by Elsevier B.V.)

Purpose: The aim of this study is to evaluate the expression of osteopontin (OPN) and its relationship with relative cytokines in patients with Graves' ophthalmopathy (GO), and to observe the effect of OPN on orbital fibroblasts (OFs) proliferation, migration, and the expression of relative cytokines, as well as the signaling pathways involved in its effect., Methods: The orbital adipose connective tissue was obtained from 24 patients with GO (12 cases of active GO, and 12 cases of inactive GO) and 12 healthy controls. OFs were isolated from orbital tissues obtained from patients with active GO who were undergoing orbital decompression surgery. Quantitative PCR and Western blot were performed to detect RNA and protein expression. The proliferation and cell migration rates of OFs were measured by methylthiazol tetrazolium (MTT) and the cell scratch test. Signaling pathway inhibitors, such as OPN monoclonal antibody 1A12, ERK1/2 inhibitor PD98059, and PI3K inhibitor LY294002, were applied to determine the involved pathways., Results: The mRNA and protein levels of OPN were increased in orbital adipose connective tissue from patients with active GO than those from patients with inactive GO (2.83-fold increase, P < 0.001; 1.91-fold increase, P < 0.05). The OPN mRNA level was positively correlated with CD40 ligand (CD40L) and hyaluronan synthases 2 (HAS2) mRNA in patients with GO. OPN promoted proliferation and migration rate of OFs and induced vascular endothelial growth factor (VEGF) and collagen I mRNA expression, and the effects were inhibited by 1A12 or LY294002., Conclusions: OPN in orbital adipose connective tissues were significantly increase in active GO, and there were significant correlations of OPN with CD40L and HAS2 mRNA levels in patients with GO. OPN promoted proliferation and migration of OFs and induced VEGF and collagen I mRNA expression in OFs through PI3K/Akt signaling pathway. This suggested a role for OPN in the pathogenesis of GO through the activation of OFs.

Glioma, the most common primary brain tumor in adults, can be difficult to discern radiologically from other brain lesions, which affects surgical planning and follow-up treatment. Recent advances in MRI demonstrate that preoperative diagnosis of glioma has stepped into molecular and algorithm-assisted levels. Specifically, the histology-based glioma classification is composed of multiple different molecular subtypes with distinct behavior, prognosis, and response to therapy, and now each aspect can be assessed by corresponding emerging MR sequences like amide proton transfer-weighted MRI, inflow-based vascular-space-occupancy MRI, and radiomics algorithm. As a result of this novel progress, the clinical practice of glioma has been updated. Accurate diagnosis of glioma at the molecular level can be achieved ahead of the operation to formulate a thorough plan including surgery radical level, shortened length of stay, flexible follow-up plan, timely therapy response feedback, and eventually benefit patients individually., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2021 Wei and Wei.)

Secondary glioblastomas (sGBM) are derived from previously lower-grade [World Health Organization (WHO) grades II or III] gliomas. Lower-grade benign-behaving gliomas may retain their former grade following recurrence, or may become malignant higher-grade glioblastomas. Prediction of tumor behavior in lower-grade gliomas is critical for individualized glioma therapy. A total of 89 patients were included between January 2000 and January 2019 in the present study to establish a nomogram via univariate and multivariate logistic regression analyses. Nomogram predictive performance was tested in the validation group. We then analyzed 36 O-6-methylguanine-DNA methyltransferase ( MGMT ) unmethylated lower-grade gliomas from patients seen at West China Hospital of Sichuan University. Survival statistics were calculated with the Kaplan-Meier method. Two clinical factors (molecular diagnosis and WHO grade), five radiological factors (location, cortical involvement, multicentricity, uniformity, and margin enhancement), one biomarker ( 1p19q codeletion), and a combination of three biomarkers ( IDH +/ ATRX -/ TP53 -) were associated with glioma upgrading. Nomograms positive for these prognostic factors had an AUC of 0.880 in the derivation group and 0.857 in the validation group. The calibration and score-stratified survival curves for the derivation group and validation group were good. An operational nomogram was published at https://warrenwrl.shinyapps.io/DynNomapp/. The overall survival of secondary gliomas in the MGMT-unmethylated cohort were influenced independently by the use of temozolomide during the treatment of formerly low-grade gliomas ( p =0.00096). Clinical and radiological factors and biomarker-based behavior-oriented nomograms may offer a feasible identification tool for the detection of sGBM precursors. This method may further assist neurosurgeons with the stratification of lower-grade glioma cases and thus the development of better, more individualized treatment plans., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2020 Wei, Zhang, Li, Yang, Xue and Wei.)

Background: Glioblastoma is the most common primary malignant brain tumor. Recent studies have shown that hematological biomarkers have become a powerful tool for predicting the prognosis of patients with cancer. However, most studies have only investigated the prognostic value of unilateral hematological markers. Therefore, we aimed to establish a comprehensive prognostic scoring system containing hematological markers to improve the prognostic prediction in patients with glioblastoma., Patients and Methods: A total of 326 patients with glioblastoma were randomly divided into a training set and external validation set to develop and validate a hematological-related prognostic scoring system (HRPSS). The least absolute shrinkage and selection operator Cox proportional hazards regression analysis was used to determine the optimal covariates that constructed the scoring system. Furthermore, a quantitative survival-predicting nomogram was constructed based on the hematological risk score (HRS) derived from the HRPSS. The results of the nomogram were validated using bootstrap resampling and the external validation set. Finally, we further explored the relationship between the HRS and clinical prognostic factors., Results: The optimal cutoff value for the HRS was 0.839. The patients were successfully classified into different prognostic groups based on their HRSs (P < 0.001). The areas under the curve (AUCs) of the HRS were 0.67, 0.73, and 0.78 at 0.5, 1, and 2 years, respectively. Additionally, the 0.5-, 1-y, and 2-y AUCs of the HRS were 0.51, 0.70, and 0.79, respectively, which validated the robust prognostic performance of the HRS in the external validation set. Based on both univariate and multivariate analyses, the HRS possessed a strong ability to predict overall survival in both the training set and validation set. The nomogram based on the HRS displayed good discrimination with a C-index of 0.81 and good calibration. In the validation cohort, a high C-index value of 0.82 could still be achieved. In all the data, the HRS showed specific correlations with age, first presenting symptoms, isocitrate dehydrogenase mutation status and tumor location, and successfully stratified them into different risk subgroups., Conclusions: The HRPSS is a powerful tool for accurate prognostic prediction in patients with newly diagnosed glioblastoma., Competing Interests: The authors declare that the research was conducted in the absence of any commercial or financial relationships that could be construed as a potential conflict of interest., (Copyright © 2020 Zhao, Li, Yang, Wei, Wang, Song, Guo, Du and Wei.)

Rhodium (Rh)-based catalysts may solve the long-standing inefficient oxidation of ethanol for direct ethanol fuel cells (DEFCs); however, the performance of ethanol oxidation reaction (EOR) on existing Rh-based catalysts are far limited. Herein, the Rh-Pb catalysts are synthesized by building Pb and Pb oxide around Rh nanodomain, which shows highly efficient splitting CC bond and facile further oxidation of as-generated C1 intermediates (CO ad and CH x fragments). It exhibits an ever-highest EOR peak mass activity of ≈2636 mA mg -1 Rh among Rh-based catalysts in alkaline media. Meanwhile, its anodic current remains ≈50% even after a 4 h durability test at 0.53 V versus RHE. As for the C1-pathway selectivity, in situ infrared adsorption spectral (IRAS) results demonstrate that it could significantly improve the production of CO 2 . More directly, the apparent faraday efficiency of EOR C1 pathway is estimated to be as high as 20% (at 0.53 V versus RHE). This Rh-Pb catalyst could hold great promise for developing the commercial DEFCs., (© 2020 Wiley-VCH GmbH.)

Guizhi Fuling Capsules is a new-type traditional Chinese medicine preparation made by modern process method. It was widely used to treat uterine fibroids, pelvic inflammation, dysmenorrhea, endometriosis, mammary gland hyperplasia and other gynecological diseases. Under the combination of disease and syndrome, the diagnosis and treatment model of &quot;Yizheng Tongbing, Yibing Tongzhi&quot; with Chinese patent medicine has been widely used in clinical practice. Meanwhile, the effectiveness and safety have been given more and more attention. Based on the effectiveness of Guizhi Fuling Capsules, this paper preliminarily summarized the dominant diseases in randomized controlled trials and systematic reviews of Guizhi Fuling Capsules. On the basis of the basic theory of traditional Chinese medicine and modern pharmacological mechanism, the clinical efficacy and mechanism of Guizhi Fuling Capsules were explored. Finally, according to the traditional Chinese medicine theory of &quot;Yizheng Tongbing, Yibing Tongzhi&quot;, all the clinical evidences were integrated to form an integrated evidence chain, so as to provide guidance for the safe and rational use of Guizhi Fuling Capsules.

Acute upper respiratory infection is one of the common infectious diseases,especially in the elderly people. Qingkailing Injection has the effect of clearing away heat and detoxifying. It can be used for external wind heat,upper respiratory tract infection,viral cold,etc. Based on 2 147 cases of upper respiratory tract infection patients using Qingkailing Injection in the medical electronic data warehouse of the information system of 16 large class-A hospitals constructed by the Institute of Basic Research in Clinical Medicine,China Academy of Chinese Medical Sciences,description analysis,Apriori calculation and recurrent network analysis were used to analyze the effect of Qingkailing Injection on upper respiratory tract infection. The clinical characteristics and the law of combined use of drugs can provide reference for the mining of clinical diagnosis and treatment characteristics and the construction of optimal and effective programs and paths. 2 147 patients with upper respiratory tract infection who used Qingkailing Injection were mostly middle-aged and elderly people over 45 years old,often combined with hypertension,ischemic cerebrovascular disease,coronary heart disease,diabetes,etc.; in treatment,it was more common to use Qingkailing Injection in combination with hormones,antipyretics and analgesics,antibiotics,nutritional support agents,antitussive,expectorant and antiasthmatic drugs,as well as traditional Chinese medicine Jiebiao agents and blood management agents. The combination of potassium chloride injection and cephalosporin injection is the most commonly used in combination with two kinds of Western medicine( 33. 2%); the combination of Shuanghuanglian and Ganmao Qingre Granules is the most commonly used in combination with two kinds of traditional Chinese medicine( 9. 13%); through the calculation of complex network group module,it is found that Qingkailing Injection is often associated with antibiotics,antipyretic and analgesic drugs,antitussive,expectorant and antiasthmatic drugs,antiviral drugs and anti infection drugs. Drugs,nutritional support agents,bronchodilators,immunomodulators and other chemical drugs are often used in combination with Chinese medicine,such as Jiebiao agents,expectorants,Qingre agents,resuscitation agents,Qufeng agents,tonics,Liqi agents,which may be related to both the treatment of upper respiratory tract infection and the basic diseases of middle-aged and elderly patients,with the theoretical characteristics of &quot; combination of disease and syndrome,corresponding formula and syndrome&quot;. Based on the real world big data complex network group module mining results provide clues for the clinical optimization scheme and path construction,and provide signals and ideas for further causal research.

Radiation therapy (RT) can effectively palliate a variety of symptoms in patients with metastatic cancer, using relatively low doses that infrequently cause major side effects. However, palliative radiation is often underutilized and sub-optimally implemented. In this study, we surveyed the Society of Palliative Radiation Oncology (SPRO) membership to identify barriers to appropriate referral for palliative RT that they encounter in their practice, and identify specific groups of physicians who radiation oncologists believed would benefit most from further education on when to refer patients. A total of 28 radiation oncologists responded to the survey with a response rate of 20.5%. On average, participants felt that referrals for palliative RT were inappropriately delayed 46.5% [standard deviation (STD) 20.2%] of the time. The most common barrier to referral for medical oncologists was thought to be potential interference with systemic therapy (33%); for primary care physicians and surgeons it was a lack of knowledge about the benefit (42%), and for palliative care physicians it was concern for patient convenience (25%). For brain metastases and spinal cord compression radiation oncology was felt to be part of the initial referral sequence more than 50% of the time, but less so for thoracic airway obstruction/bleeding (38%), esophageal obstruction (16%), or urinary obstruction/bleeding (8%), where another subspecialist was more often consulted first. Primary care, geriatric medicine, and emergency medicine were considered among the least knowledgeable specialties about palliative radiation. These hypothesis-generating findings can guide approaches to improve referral patterns for this important aspect of supportive care.

Aims: In this study, we examined the expression of lncRNA ENST00000413528 in glioma and determined its role in glioma development., Methods: LncRNA ENST00000413528 was detected in glioma tissues by lncRNA microarray. Then, we performed real-time PCR, CCK-8, colony formation assay, flow cytometry, caspase-3/7 assay and animal experiment to detect the function of ENST00000413528 in glioma after ENST00000413528 knockdown. Subsequent bioinformatics analysis, luciferase reporter assays and RNA immunoprecipitation (RIP) assay western blotting indicated possible downstream regulatory molecules. The expression of PLK1 in glioma tissues was also examined by immunohistochemistry staining., Results: Expression of ENST00000413528 was significantly increased in glioma tissues and LN229 and U251 cells. PLK1 protein could not be detected in peritumoral brain edema (PTBE) tissues; however, it showed an increasing number of positively cytoplasmic stained from WHO-Grade II to Grade III gliomas. Knockdown of ENST00000413528 in glioma cells inhibited cell proliferation and colony formation abilities, induced the G0/G1 arrest of the cell cycle, and promoted apoptosis. The dual reporter assay and RNA immunoprecipitation assay verified the interaction between ENST00000413528 and miR-593. We also demonstrated that polo-like kinase 1 (PLK1) was regulated by miR-593; PLK1 messenger RNA lacking 3'UTR partially reversed the effects caused by ENST00000413528 knockdown or miR-593 upregulation., Conclusion: lncRNA ENST00000413528 is closely related to the development of glioma via the miR-593-5p/PLK1 pathway., (© 2019 The Authors.

Palliative and supportive care education for radiation oncologists in training is essential to deliver comprehensive care to patients. Surveys on palliative care education among radiation oncology program directors and residents demonstrate a disparity in formal teaching and didactics. Integration of formal didactics, communications skills programs, and teaching modules are being piloted at academic centers. A dedicated palliative radiation oncology service has been implemented and the experience evaluated. Future directions to improve resident education in palliative care include improving access and time dedicated to formal didactics, online and interactive modules, rotation in a palliative care service, emphasis on board examinations, and consideration of an advanced palliative care fellowship for radiation oncologists. This is the first review of the available literature reviewing formal palliative education in radiation oncology training programs in the United States.

To understand the characteristics of adverse reactions and find early warning signs after intake of Guizhi Fuling Capsules. The 1 500 adverse reaction(ADR) cases of Guizhi Fuling Capsules obtained by spontaneous reporting system(SRS) from 2008 to 2017 were analyzed by proportional reporting ratios method(PRR), Bayesian confidence propagation neural network method(BCPNN) and propensity score method. The number of ADR reports increased year by year, and reached the peak in the fourth quarter of 2014. A total of 1 500 ADR cases were monitored, including 10 severe ADR cases. There were a total of 934 cases aged between 18-44 years old, accounting for 62.27%. All patients were orally administered. Among them, 1 398 patients received a single dose according to the package insert, and 57.4% had ADR within 24 h. The top five clinical manifestations of ADR were gastric dysfunction, abdominal pain, nausea, vomiting and rash, which mainly damaged the digestive system. The ADR signals were analyzed. PRR suggested that "gastric dysfunction" and "abdominal pain" were the early warning signals of Guizhi Fuling Capsules. BCPNN suggested that "nausea" and "abdominal pain" were the early warning signals of Guizhi Fuling Capsules. After the propensity score weighting method was used to control the confounding factors, the warning signals remained unchanged. The results show that Guizhi Fuling Capsules has fewer adverse reactions and is relatively safe. This study provides a basis for studying ADR of Guizhi Fuling Capsules, and guidance for drug vigilance and risk management of Guizhi Fuling Capsules.

BACKGROUND Thyroid-associated ophthalmopathy (TAO) is a common endocrine autoimmune disease. The present study explored corneal nerve changes in TAO patients. MATERIAL AND METHODS Thirty-eight Chinese TAO patients and 20 healthy individuals were included in the study. Central corneal subbasal nerve density and morphology were evaluated with in vivo laser scanning confocal microscopy and quantified using automated CCmetrics software. RESULTS The values of the central corneal subbasal nerve plexus parameters of both active and inactive TAO patients were significantly decreased compared with those of controls, including corneal nerve fiber density (CNFD) (P<0.001 for both), corneal nerve branch density (CNBD) (P<0.001 for both), corneal nerve fiber length (CNFL) (P<0.001 for both), corneal nerve fiber total branch density (CTBD) (P<0.001 for both), corneal nerve fiber area (CNFA) (P<0.001 for both), corneal nerve fiber width (CNFW) (P=0.046, P=0.027, respectively), and corneal nerve fiber fractal dimension (ACNFrD) (P<0.001 for both). In addition, CNFD and ACNFrD values were significantly lower in the active TAO patients compared with those in the inactive TAO patients (P=0.020, P=0.002, respectively). There were significant correlations between CNFD, CNBD, CNFL, CTBD, CNFA, and ACNFrD and the ocular surface parameters and activity assessment items. CONCLUSIONS Abnormal corneal subbasal nerves were observed in both active and inactive Chinese TAO patients, suggesting that nerve degeneration is associated with the disease. However, the exact underlying mechanisms remain to be elucidated.

As an antioxidant, hydrogen-rich water has been widely studied in recent years. It is mild enough neither to disturb metabolic redox reactions nor to affect signaling reactive oxygen species. Therefore, there should be no or few adverse effects of H(2). Numerous studies in biology and medicine show that hydrogen-rich water has achieved good results in nervous system, digestive system, respiratory system, heart and kidney diseases. At present, there are few studies on the treatment of eye diseases with hydrogen-rich water. This review summarizes the research progress of hydrogen-rich water for eye diseases in the domestic and foreign literatures. (Chin J Ophthalmol, 2018, 54: 631-635) .

Dysthyroid optic neuropathy (DON) is the most common cause of visual loss in thyroid associated ophthalmopathy, for which steroid pulse therapy and orbital decompression are the common treatments currently. While steroid pulse therapy was recommended as the first-choice for DON, orbital decompression remained as an indispensable therapy although controversies on such treatment still exist. The mechanism, approaches and outcomes of orbital decompression, as well as its advantages and disadvantages over steroid pulse therapy were retrospectively reviewed, and it was suggested that the combination therapy of steroid pulse therapy and surgical decompression might be the better choice for the treatment of DON.

To systemically evaluate the post-marketing safety of Guizhi Fuling Jiaonang. Computer retrieval was conducted in Medline, EMbase, the Web of Science, Clinical Trials. Gov, the Cochrane Library, CNKI, VIP, WanFang Data and CBM to collect relevant information. The papers were then screened according to inclusion and exclusion criteria. A total of 234 papers were included in this study, including 164 randomized controlled trials, 7 quasi-randomized controlled trials, 8 non-randomized controls, 56 case series, and 1 cohort study. The patients were only treated with Guizhi Fuling Jiaonang in 56 studies, and Guizhi Fuling Jiaonang was combined with other drugs in 178 studies. The total ADRs/AEs incidence was 1.99% in single use of Guizhi Fuling Jiaonang, and 8.21% in combined use, but showing no severe adverse reactions. Gastrointestinal system damage was most common in mild ADRs. In this study, it was found that the overall safety of Guizhi Fuling Jiaonang was acceptable. The direct evidences of the drug's safety case reports were systematically analyzed in this study, but the mechanism study on the safety of the drug after marketing or the prospective long-term clinical observation study was not sufficient, so the further studies on the safety of drug use should be conducted in order to provide better guidance for clinical medication., Competing Interests: The authors of this article and the planning committee members and staff have no relevant financial relationships with commercial interests to disclose., (Copyright© by the Chinese Pharmaceutical Association.)

Purpose: The purpose of this study was to assess the state of palliative and supportive care (PSC) and palliative radiation therapy (RT) educational curricula in radiation oncology residency programs in the United States., Methods and Materials: We surveyed 87 program directors of radiation oncology residency programs in the United States between September 2015 and November 2015. An electronic survey on PSC and palliative RT education during residency was sent to all program directors. The survey consisted of questions on (1) perceived relevance of PSC and palliative RT to radiation oncology training, (2) formal didactic sessions on domains of PSC and palliative RT, (3) effective teaching formats for PSC and palliative RT education, and (4) perceived barriers for integrating PSC and palliative RT into the residency curriculum., Results: A total of 57 responses (63%) was received. Most program directors agreed or strongly agreed that PSC (93%) and palliative radiation therapy (99%) are important competencies for radiation oncology residents and fellows; however, only 67% of residency programs had formal educational activities in principles and practice of PSC. Most programs had 1 or more hours of formal didactics on management of pain (67%), management of neuropathic pain (65%), and management of nausea and vomiting (63%); however, only 35%, 33%, and 30% had dedicated lectures on initial management of fatigue, assessing role of spirituality, and discussing advance care directives, respectively. Last, 85% of programs reported having a formal curriculum on palliative RT. Programs were most likely to have education on palliative radiation to brain, bone, and spine, but less likely on visceral, or skin, metastasis., Conclusions: Residency program directors believe that PSC and palliative RT are important competencies for their trainees and support increasing education in these 2 educational domains. Many residency programs have structured curricula on PSC and palliative radiation education, but room for improvement exists in management of fatigue, assessing role of spirituality, and discussion regarding advance care planning., (Copyright © 2016 American Society of Radiation Oncology.

Traumatic brain injury (TBI) often leads to impaired consciousness. Recent diffusion tensor imaging studies associated consciousness with imaging metrics including fractional anisotropy (FA) and apparent diffusion coefficient (ADC). We evaluated their correlations and determined the best index in candidate regions. Six databases were searched, including PubMed and Embase, and 16 studies with 701 participants were included. Data from region-of-interest and whole-brain analysis methods were meta-analysed separately. The FA-consciousness correlation was marginal in the whole-brain white matter (r = 0.63, 95% CI [0.47, 0.79], p = 0.000) and the corpus callosum (CC) (r = 0.60, 95% CI [0.48, 0.71], p = 0.000), and moderate in the internal capsule (r = 0.48, 95% CI [0.24, 0.72], p = 0.000). Correlations with ADC trended negative and lacked significance. Further subgroup analysis revealed that consciousness levels correlated strongly with FA in the CC body (r = 0.66, 95% CI [0.43, 0.89]), moderately in the splenium (r = 0.58, 95% CI [0.38, 0.78]), but insignificantly in the genu. In conclusion, FA correlates better with consciousness levels than ADC in TBI. The degree of correlation varies among brain regions. The CC (especially its splenium and body) is a reliable candidate region to quantitatively reflect consciousness levels.

Palliative radiotherapy (PRT) improves patient quality of life (QoL) through alleviating cancer-associated symptoms such as pain, bleeding, and ulceration. Palliative management of patients with skin malignancies requires consideration of cosmetic and psychosocial outcomes as QoL measures. In this review, we highlight the current literature and advances in the use of PRT for patients with the three most commonly encountered forms of skin malignancies: basal cell carcinoma (BCC), squamous cell carcinoma (SCC), and melanoma. The disease course and sensitivity to radiation varies, thus dictating the palliative goal and scheduling for PRT.

Purpose: Radiation oncologists are frequently involved in providing palliative and supportive care (PSC) for patients with advanced cancers through delivery of palliative radiation. Whether they are confident in their ability to assess and initiate treatments for pain, nonpain, and psychosocial distress is unknown. The American Society for Radiation Oncology surveyed its practicing members in the United States on self-assessment of their primary PSC skills and access to continuing medical education on PSC., Methods: We electronically surveyed 4093 practicing radiation oncologists in the United States. The survey consisted of 16-questions in 5 sections 1 : demographics, 2 PSC training, 3 domains of PSC, 4 perceived barriers as a radiation oncologist to initiate advanced care planning, and 5 discussion of prognosis., Results: The survey was e-mailed to 4093 American Society for Radiation Oncology members, and 649 responses were received (response rate 16%). The majority (91%) of radiation oncologists surveyed believe PSC is an important competency for radiation oncologists. Most radiation oncologists reported that they are moderately confident in their ability to assess and manage pain and gastrointestinal symptoms, but less confident in their ability to manage anorexia, anxiety, and depression. Despite areas of decreased confidence, a large number (42%) of radiation oncologists do not receive any additional PSC education beyond their residency training. Lastly, a perceived fear of upsetting referring medical oncologists and lack of clinic time are concerns for radiation oncologists who may want to initiate goals of care/advance care planning discussions with patients and their families., Conclusion: Radiation oncologists are more confident in their ability to assess and manage pain than in their ability to manage depression, anxiety, anorexia, and fatigue. There is a need for increasing continuing medical educational efforts in PSC for practicing radiation oncologists, and strengthening PSC training in residency programs., (Published by Elsevier Inc.)

American Association of Physicists in Medicine (AAPM) Task Group 176 evaluated the dosimetric effects caused by couch tops and immobilization devices. The report analyzed the extensive physics-based literature on couch tops, stereotactic body radiation therapy (SBRT) frames, and body immobilization bags, while noting the scarcity of clinical reports of skin toxicity because of external devices. Here, we present a clinical case report of grade 1 abdominal skin toxicity owing to an abdominal compression device. We discuss the dosimetric implications of the utilized treatment plan as well as post hoc alternative plans and quantify differences in attenuation and skin dose/build-up between the device, a lower-density alternative device, and an open field. The description of the case includes a 66-year-old male with HER2 amplified poorly differentiated distal esophageal adenocarcinoma treated with neoadjuvant chemo-radiation and the use of an abdominal compression device. Radiation was delivered using volumetric modulated arc therapy (VMAT) with 2 arcs using abdominal compression and image guidance. The total dose was 50.4Gy delivered over 40 elapsed days. With 2 fractions remaining, the patient developed dermatitis in the area of the compression device. The original treatment plan did not include a contour of the device. Alternative post hoc treatment plans were generated, one to contour the device and a second with anterior avoidance. In conclusion, replanning with the device contoured revealed the bolus effect. The skin dose increased from 27 to 36Gy. planned target volume (PTV) coverage at 45Gy was reduced to 76.5% from 95.8%. The second VMAT treatment plan with an anterior avoidance sector and more oblique beam angles maintained PTV coverage and spared the anterior wall, however at the expense of substantially increased dose to lung. This case report provides an important reminder of the bolus effect from external devices such as abdominal compression.

Purpose: Nonarteritic anterior ischemic optic neuropathy (NAION) is a multifactorial disease, and recently epidemiologic studies have investigated the association between obstructive sleep apnea (OSA) and NAION. A systematic review of the association of OSA and NAION has not been performed. Therefore, the current meta-analysis was performed to assess such potential association between OSA and risk of NAION., Methods: A systematic search of PubMed and EMBASE databases was performed for published studies evaluating the association between OSA and NAION. The summary odds ratios (ORs) and 95% confidence intervals (CIs) were calculated for categorical risk estimates. Sensitivity analyses and subgroup analyses were also performed to assess the robustness of pooled outcomes., Results: A total of four prospective cohort studies and one case-control study met our inclusion criteria. The pooled OR of developing NAION in the subjects with OSA was 6.18 (95% CI, 2.00-19.11) versus non-OSA controls. Sensitivity analyses showed that no matter one study excluded, the pooled OR did not change significantly, which indicated that the evidence was robust. In subgroup analyses, a significant association was seen in studies matched systemic risk factors (OR, 5.00; 95% CI, 2.22-11.25), but not in those non-matched. The magnitude and direction of effects were also affected by methodological variability, including study design, and diagnosis of OSA., Conclusions: The findings from this meta-analysis supported the robust evidence that OSA was a strong independent risk factor of NAION. Relative to non-OSA controls, the subjects with OSA were found to have a more than sixfold risk of NAION. In future, more well-designed studies are needed to confirm these findings.

Purpose: To examine the density and morphology of Langerhans cells (LCs) in the cornea of patients with thyroid-associated ophthalmopathy (TAO)., Methods: Forty patients with TAO and 20 healthy volunteers were studied. All subjects underwent a thorough ophthalmic examination of both eyes. The ocular surface status was assessed by Ocular Surface Disease Index (OSDI) symptom questionnaires, tear break-up time (BUT), fluorescein staining and the Schirmer test. Laser scanning in vivo confocal microscopy was applied to evaluate the LC density and morphology in both central and peripheral cornea. The correlations between confocal microscopy data and clinical data were also analyzed., Results: The OSDI and fluorescein staining values were significantly higher, while BUT and Schirmer test scores were lower in both active and inactive TAO patients compared to the controls. Central LC densities of patients with active TAO (76.38 ± 67.77 cell/mm(2)) and inactive TAO (47.49 ± 38.58 cell/mm(2)) were both significantly higher than those of the controls (21.46 ± 21.74 cell/mm(2)). The number of LCs in the peripheral cornea was also significantly increased in the active TAO group (131.53 ± 74.18 cell/mm(2)) compared to the control group (70.21 ± 37.76 cell/mm(2)). Central LC morphology (LCM) values were significantly higher in both active (1.77 ± 0.63) and inactive (1.51 ± 0.63) TAO groups compared to the control group (1.01 ± 0.80), whereas peripheral LCM scores of the two TAO groups were increased without statistical significance. There were significant correlations between both central LC density and central LCM scores and clinical data, including clinical activity score, OSDI and Schirmer test scores, and between peripheral LC density and OSDI and Schirmer test scores. No significant correlations were found between peripheral LCM scores and clinical data., Conclusions: The increase of corneal LCs in density and maturation in patients with TAO reflects an activated state of the local immune system, which indicates an inflammatory process in the cornea of TAO.

Purpose: To investigate the relationship between abdominal chemoradiation (CRT) for locally advanced cancers and bone mineral density (BMD) reduction in the vertebral spine., Materials and Methods: Data from 272 patients who underwent abdominal radiation therapy from January 1997 to May 2015 were retrospectively reviewed. Forty-two patients received computed tomography (CT) scans of the abdomen prior to initiation and at least twice after radiation therapy. Bone attenuation (in Hounsfield unit) (HU) measurements were collected for each vertebral level from T7 to L5 using sagittal CT images. Radiation point dose was obtained at each mid-vertebral body from the radiation treatment plan. Percent change in bone attenuation (Δ%HU) between baseline and post-radiation therapy were computed for each vertebral body. The Δ%HU was compared against radiation dose using Pearson's linear correlation., Results: Abdominal radiotherapy caused significant reduction in vertebral BMD as measured by HU. Patients who received only chemotherapy did not show changes in their BMD in this study. The Δ%HU was significantly correlated with the radiation point dose to the vertebral body (R=-0.472, P<0.001) within 4-8 months following RT. The same relationship persisted in subsequent follow up scans 9 months following RT (R=-0.578, P<0.001). Based on the result of linear regression, 5 Gy, 15 Gy, 25 Gy, 35 Gy, and 45 Gy caused 21.7%, 31.1%, 40.5%, 49.9%, and 59.3% decrease in HU following RT, respectively. Our generalized linear model showed that pre-RT HU had a positive effect (β=0.830) on determining post-RT HU, while number of months post RT (β=-0.213) and radiation point dose (β=-1.475) had a negative effect. A comparison of the predicted versus actual HU showed significant correlation (R=0.883, P<0.001) with the slope of the best linear fit=0.81. Our model's predicted HU were within ±20 HU of the actual value in 53% of cases, 70% of the predictions were within ±30 HU, 81% were within ±40 HU, and 90% were within ±50 HU of the actual post-RT HU. Four of 42 patients were found to have vertebral body compression fractures in the field of radiation., Conclusions: Patients who receive abdominal chemoradiation develop significant BMD loss in the thoracic and lumbar vertebrae. Treatment-related BMD loss may contribute to the development of vertebral compression fractures. A predictive model for post-CRT BMD changes may inform bone protective strategies in patients planned for abdominal CRT., (Copyright © 2016 Elsevier Ireland Ltd. All rights reserved.)
