This study evaluates the efficacy and safety of plasmapheresis without plasma transfusion tandem with chemotherapy in treating multiple myeloma (MM).This retrospective study involves seventy-two patients, newly diagnosed with multiple myeloma, divided into two groups; one with plasmapheresis without plasma transfusion tandem with the chemotherapy group (Trial group), while the second was chemotherapy group (Control group). The levels of Plasma Globulin, β2-microglobulin, Creatinine, Vascular endothelial growth factor (VEGF), and IL-6 were monitored after plasmapheresis, at initial diagnosis, and after four chemotherapy courses. Overall response rate of groups after four courses of chemotherapy was analyzed, and the adverse events were recorded.The baseline data showed that sixty-seven percent of patients were at the ISS III stage and showed more severe renal insufficiency in the Trial group. The Plasma Globulin, β2-microglobulin, VEGF and IL-6 levels were significantly different between the two groups during the initial diagnosis. After three times plasmapheresis, Plasma Globulin, β2-microglobulin, VEGF, and IL-6 were significantly reduced in the plasmapheresis group. The Creatinine levels were also lowered, but the differences were not statistically significant. After four courses of chemotherapy, the levels of VEGF and IL-6 in the two groups were significantly reduced than the initial diagnosis; the differences were statistically considerable. No adverse events were found in the trial group as compared to the control group.Plasmapheresis reduces Globulin, β2-microglobulin, serum VEGF and IL-6 levels in MM, improves renal functions, and releases some patients from dialysis dependence.

Hematopoietic cell transplantation (HCT) is a potentially curative treatment for many hematologic and nonhematologic disorders. Graft-versus-host-disease (GVHD) in its acute or chronic form remains the most important nonrelapse post-HCT complication. Biomarkers offer objective, unbiased information on systemic disorders, and significant attention has focused on identifying biomarkers for GVHD. Ideally, a GVHD biomarker is actionable, with the results of biomarker testing used to guide clinical management of disease and clinical trial design. Although many GVHD biomarkers have been identified, none have been properly qualified for clinical use. The National Institutes of Health (NIH) and Food and Drug Administration (FDA) have provided biomarker subtype definitions; however, confusion remains about the proper definition and application of these subtypes in the HCT field. The 2014 NIH consensus development project provided a framework for the development of biomarkers for clinical practice. This review aims to clarify the biomarker subtype definitions and reemphasize the developmental framework. Armed with this knowledge, clinicians can properly translate GVHD biomarkers for clinical use.

To investigate the relationship between systemic inflammatory response and short-term mortality in patients with non-cirrhotic chronic severe hepatitis (CSH) by using several indicators of inflammation including neutrophil-to-lymphocyte ratio (NLR), neutrophil (NEU), white blood cell (WBC), platelet-to lymphocyte ratio (PLR), and monocyte-to-lymphocyte ratio (MLR).Data were collected from two prospectively enrolled CATCH-LIFE noncirrhotic cohorts. Cox regression analysis was used to investigate the association between systemic inflammatory biomarkers and 90-day liver transplant (LT)-free mortality. A generalized additive model (GAM) was used to illustrate the quantitative curve relationship between NLR and 90-day LT-free mortality. Kaplan-Meier method was used to estimate the 90-year LT-free survival.The prevalence of CSH was 20.5% (226/1103). The 28-day and 90-day LT-free mortality rates were 17.7% and 26.1%, respectively, for patients with non-cirrhotic CSH. Patients with no infection accounted for 75.0% of all CSH patients, and NLR was independently associated with 90-day LT-free mortality. NLR of 2.9 might be related to disease deterioration in CSH patients without infection.NLR may be an independent risk factor for 90-day LT-free mortality in patients with non-cirrhotic chronic liver disease. A NLR of 2.9 as the cut-off value can be used to predict disease aggravation in CSH patients without infection.

The effect of prolonged pulse therapy with vincristine and dexamethasone (VD) during maintenance therapy on the outcome of paediatric patients with TCF3-PBX1 positive acute lymphoblastic leukaemia (ALL) remains uncertain. We conducted non-inferiority analysis of 263 newly diagnosed TCF3-PBX1 positive ALL children who were stratified and randomly assigned (1:1) to receive seven additional VD pulses (the control group) or not (the experimental group) in the CCCG-ALL-2015 clinical trial from January 2015 to December 2019 (ChiCTR-IPR-14005706). There was no significant difference in baseline characteristics between the two groups. With a median follow-up of 4.2 years, the 5-year event-free survival (EFS) and 5-year overall survival (OS) in the control group were 90.1% (95% confidence interval [CI] 85.1-95.4) and 94.7% (95% CI, 90.9-98.6) comparable to those in the experimental group 89.2% (95% CI 84.1-94.7) and 95.6% (95% CI 91.8-99.6), respectively. Non-inferiority was established as a one-sided 95% upper confidence bound for the difference in probability of 5-year EFS was 0.003, and that for 5-year OS was 0.01 by as-treated analysis. Thus, omission of pulse therapy with VD beyond one year of treatment did not affect the outcome of children with TCF3-PBX1 positive ALL.

Microneedling (MN) therapy is one of minimal invasive operations with needles rolled over skin to puncturing the epidermis, and it is becoming a widely used treatment during various dermatological diseases includes androgenetic alopecia (AGA).The purpose of the current study is to investigate the clinical observation and safety of MN combined with 5% minoxidil on triggering hair growth in AGA patients.This retrospective study has analyzed 18 AGA patients who were treated by MN in combination with 5% minoxidil topical solution between July 2021 and February 2022. All patients received six sessions of treatment under aseptic condition at an interval of 1 week. Assessment of hair regrowth was done at the baseline and 10 weeks by photography, investigator, and patient assessment global scoring table on clinical improvement, and the patient's final satisfaction was investigated.According to the standardized 7-point scale, mean scores of investigator and participant assessments were 1.44 ± 0.61 and 1.66 ± 0.59, respectively, indicating that the hair appearance was considerably improved by MN combined with 5% minoxidil treatment. Fifteen patients (83.3%) were satisfied with the improvement in hair growth. No severe adverse events were noted in patients during and after the procedure.The combination of the length of 1.5 mm MN and 5% minoxidil in the treatment of AGA showed efficacy with high safety, which is worthy of clinical application.

Microneedling refers to a minimally invasive technique that uses multiple fine needles targeted skin epidermis for mechanical stimulation to obtain therapeutic or cosmetic effects. It is suitable for the treatment of a variety of dermatological conditions, including androgenetic alopecia (AGA).This article aims to make a comprehensive review of the relevant studies on microneedling for the management of AGA.Extensive literature search was performed using PubMed, Web of Science, and EBSCO databases. 4 in vivo studies and 25 clinical trials were included according to the inclusion and exclusion criteria.The effects of microneedling on AGA was investigated in animal experiments. Several clinical trials, including randomized controlled trials, strengthen the validity of the findings. Microneedling therapy showed some encouraging results with minor complications when used alone or in combination with topical products.Microneedling appears to be a safe and effective therapeutic option for AGA. Larger and more randomized controlled trials regarding the role of microneedling in AGA are strongly recommended to provide more definitive evidence.This journal requires that authors assign a level of evidence to each article.

Hemophagocytic lymphohistiocytosis (HLH) is a life-threatening systemic hyperinflammatory syndrome. The central pathogenesis is an explosive cytokine storm characterized by a significant increase in proinflammatory cytokines, including IL-1β, IL-6, IL-18, IFN-γ, and TNF-α. Meanwhile, negative regulatory factors, such as IL-10 and TGF-β, are also related to the production of HLH. Exploring the specific mechanism of cytokine storms could provide ideas regarding targeted therapy, which could be helpful for early treatment to reduce the mortality of HLH. Although some research has focused on the advantages of targeted therapies, there is still a lack of a comprehensive discourse. This article attempts to summarize the mechanisms of action of various cytokines and provide a therapeutic overview of the current targeted therapies for HLH.

Semen analysis (SA) plays a key role in guiding treatments of male reproductive diseases and infertility due to male factors; however, it remains challenging to conduct an accurate SA due to lack of standardization, highly subjective assessments, and problems with automated procedures. Therefore, quality assurance (QA) and teaching courses are essential for making the laboratory results more consistent.The external quality assurance (EQA) scheme was organized by national human sperm bank technology training bases in Guangdong province in China between 2009 and 2020. Until 2020, 124 laboratories from China participated in the EQA program. The EQA scheme per year has been organized involving two semen aliquots for sperm concentration, two video recordings for motility, and two smears for sperm morphology. All samples used in the EQA scheme were obtained from different healthy donors or patients.We estimated that the median coefficient of variation (CV) of sperm concentration, ignoring the method used, was 26.6%. Using a 100 µm deep counting chamber led to a decreasing CV of 13.6%. For sperm motility, the median CV of nonprogressive motility was high (50.8%), but the CV of progressive motility (13.2%), immotile sperm (14.3%), and total motility (11.8%) were acceptable. The morphology assessment revealed large variability (44.4%) irrespective of the classification criteria.The reduction of interlaboratory variability is still a challenge during SA in China. Therefore, it is critical to increase awareness of joining EQA schemes and establish standardized training centers to follow WHO-recommended procedures toward Chinese standards.

Background. Traditionally, serum CEA and CA19-9 levels are good prognostic factors for gastric cancer. Many gastric cancer patients do not have elevated CEA or CA19-9 levels even at a very advanced stage. This study investigates the significance of the modified Glasgow prognostic score (mGPS) for the survival of gastric cancer patients with normal CEA and CA19-9. Methods. We retrospectively examined 488 curatively resected gastric cancer patients with normal preoperative serum levels of CEA and CA19-9 to evaluate the prognostic ability of mGPS for overall survival. The prognostic significance was analyzed by univariate and multivariate analyses. Results. Age, hemoglobin, white cell count, and neutrophils were each significantly correlated with the mGPS. Multivariate analyses showed that tumor location (HR, 0.803; 95% CI, 0.667–0.966; P = 0.020 ), TNM stage (HR, 2.714; 95% CI, 2.250–3.275; P < 0.001 ), and mGPS (HR, 1.042; 95% CI, 1.105–1.772; P = 0.023 ) were significantly associated with overall survival. Significant correlations were found between overall survival and mGPS. The Kaplan–Meier analysis demonstrated significant differences among patients with mGPS of 0, 1, and 2 P < 0.001 , with the mortality rate being higher for patients with a higher mGPS. Conclusion. The mGPS can predict survival in gastric cancer patients with normal CEA and CA19-9.

In this open-label, single-arm, phase I/II clinical trial, we evaluated the efficacy of anti-B cell maturation antigen (BCMA) chimeric antigen receptor (CAR)-T cell (HDS269B) therapy in 49 relapsed/refractory multiple myeloma (RRMM) patients, including 20 with Eastern Cooperative Oncology Group (ECOG) grade 3-4. After HDS269B infusion (9 × 10

Metastatic progression is a major burden for breast cancer patients and is associated with the ability of cancer cells to overcome stressful conditions, such as nutrients deprivation and hypoxia, and to gain invasive properties. Autophagy and epithelial-to-mesenchymal transition are critical contributors to these processes. Here, we show that the P2X4 purinergic receptor is upregulated in breast cancer biopsies from patients and it is primarily localised in endolysosomes. We demonstrate that P2X4 enhanced invasion in vitro, as well as mammary tumour growth and metastasis in vivo. The pro-malignant role of P2X4 was mediated by the regulation of lysosome acidity, the promotion of autophagy and cell survival. Furthermore, the autophagic activity was associated with epithelial-to-mesenchymal transition (EMT), and this role of P2X4 was even more pronounced under metabolic challenges. Pharmacological and gene silencing of P2X4 inhibited both autophagy and EMT, whereas its rescue in knocked-down cells led to the restoration of the aggressive phenotype. Together, our results demonstrate a previously unappreciated role for P2X4 in regulating lysosomal functions and fate, promoting breast cancer progression and aggressiveness.

Adiponectin is an important adipocytokine and has been associated with the risks of gastrointestinal cancers (GICs). Mendelian randomization (MR) analysis is needed to assess the causal relationships between adiponectin and GICs.We retrieved the summary data of genome-wide association studies for adiponectin and six types of GICs in East Asians. A series of quality control steps were performed to select the eligible genetic instrumental tools. Horizontal pleiotropy and between-SNP heterogeneity were tested to choose the primary MR method. We also conducted sensitivity analyses to test the robustness of the main findings.We detected neither heterogeneity nor horizontal pleiotropy for the eligible SNPs in all of the MR analyses. Inverse variance weighted (IVW) was therefore used as the primary method, and suggested that per 10% increase in log-transformed adiponectin level was significantly associated with a decreased risk of gastric cancer (odds ratio [OR] = 0.88, 95% CI 0.81, 0.96), whereas with an increased risk of hepatocellular carcinoma (OR = 1.26, 95% CI 1.09, 1.44) and of biliary tract cancer (OR = 1.54, 95% CI 1.12, 2.12). However, only the association between adiponectin and HCC risk was statistically significant after correction for multiple testing. No statistically significant association was detected between adiponectin and esophageal (OR = 1.05, 95% CI 0.89, 1.23), pancreatic (OR = 1.04, 95% CI 0.78, 1.37), and colorectal cancers (OR = 1.00, 95% CI 0.93, 1.07). Sensitivity analyses did not find contradictory results.High level of adiponectin may have a causal effect on and can serve as a biomarker for the carcinogenesis of gastric cancer, hepatocellular carcinoma, and biliary tract cancer.

Objective. To investigate the effect and safety of 3D printing technology in proximal femoral osteotomy in children with developmental dysplasia of the hip. Methods. 40 cases of children with developmental dysplasia of the hip treated by pelvic osteotomy combined with proximal femoral osteotomy at Ningbo No. 6 Hospital from January 2017 to December 2019 were retrieved and retrospectively analyzed. Among them, 20 cases received preoperative measurement and design assisted by 3D printing technology (the 3D printing group), and 20 cases received conventional preoperative measurement and design (the conventional group). Results. All patients were followed up for an average of 25 (12~36) months. During the follow-up, there were no complications such as infection, fracture of internal fixation, or malunion of osteotomy. Compared with the conventional group, the 3D printing group had a shorter operation time, less intraoperative blood loss, and fewer intraoperative X-ray fluoroscopies (all p < 0.05 ). In the last follow-up, the clinical efficacy was evaluated by the McKay standard: in the 3D printing group, 14 cases were excellent, 5 cases were good, and 1 case was fair. In the conventional group, 10 cases were excellent, 9 cases were good, and 1 case was fair ( Z = − 0.382 , p > 0.05 ). Conclusion. Preoperative 3D printing of bilateral femur and other large physical models is accurate, which is ideal for the development of individual preoperative planning. Proximal femoral osteotomy using preoperative measurements and simulated surgical data improves the safety of the operation.

Background The average body weight of the Chinese population is rising rapidly over the past two decades and the old 2001 body mass index (BMI) cut-off value for malnutrition may underestimate malnutrition diagnosis. We explored the BMI cut-off value for malnutrition diagnosis based on national BMI data over the past 30 years and applied it to the Global Leadership Initiative on Malnutrition (GLIM) criteria when investigating malnutrition in hospitalized older adult patients. Methods To explore the BMI cut-off value for malnutrition, we established a linear stepwise model to predict the annual increasing BMI trend based on data from the national BMI dataset (1990-2009). The new cut-off value was applied to a large-scale dataset from a cross-sectional study pertaining to older hospitalized patients (≥65) recruited from 30 large hospitals in China. Results The average BMI increased from 21.8 to 23 kg/m2 in two decades. Using the linear model, we calculated that the net BMI increase will be 1.49 kg/m2 from 2009 to 2019. We subsequently proposed that the BMI cut-off value for malnutrition should rise to 20 kg/m2 . This cut-off value was applied to the validation dataset, containing 8,725 patients, and the GLIM-determined malnutrition rate was 24.58% (using the NRS-2002) and 23.32% (using the MNA-SF). The results significantly differed from those obtained using the 2001 Chinese BMI criteria (p Conclusion The GLIM tool has good applicability in Asian populations, especially in Chinese older adult patients. The BMI cut-off value for malnutrition should be adjusted to 20 kg/m2 for Chinese adults. This article is protected by copyright. All rights reserved.

A lysosomal targeted fluorescent probe based on coumarin for monitoring hydrazine (N2H4) in living cells was designed and synthesised. The novel fluorescent probe Cou-Lyso-N2H4, in response to N2H4, exhibited good selectivity, low cytotoxicity, and lysosomal localization, which could be suitable for studying the harmfulness of N2H4 in subcellular organelles during various physiological processes.

We aimed to explore a novel method for ear reconstruction stent remodeling to achieve high patient satisfactory outcomes.This study is a retrospective review of patients with congenital or acquired ear defects who were prepared for one-stage ear reconstruction with high-density porous polyethylene stent between May 2020 and May 2021. A standardized data collection template was used to collect related variables. In this study, the detailed reconstruction surgery process is carefully described, and the postoperative healing process of the ear reconstruction was closely observed.A total of 26 patients for one-stage ear reconstruction with high-density porous polyethylene stent or autogenous costal cartilage scaffolds were admitted to the department of plastic surgery in our hospital between May 2020 and May 2021. All patients were followed until their ear flaps were alive and details of the ear shape were revealed. The patients with new remolding method were no severe complications and only a patient had stent exposure, and were highly satisfied with both appearance and function.The application of novel remodeling method is a promising way for ear reconstruction stent shaping with little postoperative complication and excellent postoperative patient satisfaction.

The role of vitamin C in sepsis is still controversial, we aimed to systematically review the efficacy of intravenous vitamin C supplementation in the treatment of sepsis.MEDLINE, EmBase, Web of Science, WanFang Data and CNKI were comprehensively searched to collect randomized controlled trails (RCTs) of vitamin C supplementation for patients with sepsis or sepsis shock from January 2000 to March 2021. Two researchers independently screened the literature, extracted the data and accessed the risk of bias in the included studies; meta-analysis was then performed by using Revman 5.4 software.A total of 10 RCTs involving 1400 participants were included. The results of meta-analysis showed that intravenous vitamin C supplementation can improve SOFA (ΔSOFA) within 72 h [RR = 1.32,95% CI(0.80,1.85), P0.0001] of septic patients. There were no difference on short term mortality (28-30d)[RR = 0.83,95% CI(0.65,1.05), P = 0.11], long term mortality (90d) [RR = 1.16,95% CI(0.82,1.66), P = 0.40], hospital LOS[RR = 0.15,95% CI(-0.73,1.03), P = 0.55], ventilator-free days[RR = 0.09,95% CI(-0.24,0.42), P = 0.60], ICU-LOS[RR = 0.22,95% CI(-0.13,0.57), P = 0.22], between two groups. The results of Subgroup analysis showed that intravenous vitamin C alone can reduce the risk of short term mortality (28-30d) [RR = 0.61,95% CI(0.47,0.79), P = 0.0002]of sepsis patients.Based on current RCTs, our work indicated that mono-intravenous vitamin C therapy may reduce short-term mortality of sepsis patients, and it may protect organ functions. Due to the limitation of the quantity and quality of included studies, the above conclusions need to be verified by more large scale and high quality randomized control trials.

Background: Capsular contracture is common in breast augmentation and reconstruction surgery. The present systematic review discusses the safety of textured and smooth implants in the submuscular position. Methods: A literature search was conducted on PubMed and EMBASE from inception until June 2020. The primary outcome was reduction of capsular contracture (Baker grade); others included time of capsular contracture onset, implant position/rupture rate/surface, hematoma/seroma risk, surgeon assessment and patient satisfaction. A total of 7731 patients were included from six publications. Results: The overall risk rate for capsular contracture increased from 7.6 to 25% in 10 years. The capsular contracture rates in textured and smooth implants were 3–14% and 6–20%, respectively, and no significant difference between implants was observed when the implants were placed submuscularly. Submuscular placement and textured implants also reduced the incidence of other complications. Conclusion: This systematic review suggests that appropriate placement reduces capsular contracture rate, irrespective of implant surface.

Obesity and overweight conditions have become major health challenges worldwide. The exploration of effective weight loss strategies is essential. Nudges are currently advancing approaches that represent a new and better method for changing the behaviors of people. However, the effectiveness of nudge interventions on weight loss in overweight people who may be obese has not been synthesized in a systematic manner. In this study, a systematic literature search was performed. Only randomized controlled trials (RCTs) were considered. Weighted mean differences (WMDs) and 95% confidence intervals (CIs) were calculated as summary statistics. In total, 25 RCTs involving a population of 5,929 individuals were included. Significant effects of the nudge strategy on weight loss (WMD: -0.96 kg, 95% CI: -1.49 to -0.43), body mass index (WMD: -0.3 kg/m2, 95% CI: -0.41 to -0.19) and waist circumference (WMD: -0.75 cm, 95% CI: -1.23 to -0.27) were observed. The subgroup analysis showed that the reduction in body weight associated with nudge interventions was significant in younger and more obese people. Moreover, the effect of nudge intervention on weight loss weakened over time. Overall, the nudge strategy can promote changes in weight loss, body mass index and waist circumference of adults, albeit at a mild magnitude and in particular types of individuals. Nudge strategies can be recommended to clinical practitioners and policy-makers to promote obesity management.

According to the taste analysis of Pudilan Xiaoyan Oral Liquid, the unpleasant taste of the oral liquid is mainly caused by the inherent taste of Chinese medicine and the taste introduced in the preparation process, which leads to its unpopularity among children. Therefore, aiming at the special children patient group, Xiaoer Pudilan Xiaoyan Syrup was developed via technology optimization and dosage form improvement to improve the unpleasant taste and enhance the medication compliance among children. Based on the material properties of Pudilan Xiaoyan Oral Liquid and Xiaoer Pudilan Xiaoyan Syrup extracts, the authors compared the properties(pH, density, turbidity, viscosity, chromaticity, particle size), taste, content of five quality markers and in vivo pharmacokinetic characteristics of these two preparations, to evaluate the suitability of Xiaoer Pudilan Xiaoyan Syrup. The results showed that compared with those of Pudilan Xiaoyan Oral Liquid, the pH, density, turbidity, viscosity and chromaticity of Xiaoer Pudilan Xiaoyan Syrup were significantly changed, and the unpleasant taste was reduced by 26%; the transfer rate of the main active ingredients chicoric acid was increased, while the transfer rate of baicalin had small difference from that of the oral liquid. In addition, pharmacokinetics revealed that the total absorption amount of baicalin in vivo was higher, and the time to peak T_(max) of baicalin and oroxindin in the syrup and the mean residence time MRT_(last )of corynoline in vivo were significantly prolonged. The absorption degree of Xiaoer Pudilan Xiaoyan Syrup and Pudilan Xiaoyan Oral Liquid in the body was the same: baicalingt;oroxindingt;corynoline. The new dosage form process was simpler than that of the original dosage form, safe, environmentally friendly, reasonable and feasible, meeting the mass production demand. This provided a basis for the reasonable and scientific optimization of Xiaoer Pudilan Xiaoyan Syrup, and also laid a foundation for its further safe and rational use, so as to expand the clinical application in children.

Human esophagus carcinoma (EC) is one of the most common malignant tumors, especially in Africa and Asia including China. In EC initiation and progression, genetic and epigenetic aberrations have been reported to play a major role, but the underlying molecular mechanisms are largely unknown. In this study, the miR-30e levels were analyzed in human EC tissues and TCGA databases, and the results demonstrated that miR-30e expression in EC tissues was significantly decreased compared to adjacent normal tissues. To further investigate the role of miR-30e in cancer cells, we found that forced expression of miR-30e dramatically inhibited cell proliferation, invasion, tube formation, and colony formation of cancer cells. To determine the underlying mechanism of miR-30e, we found that RPS6KB1 was a direct target of miR-30e by binding to its 3'-UTR, which was verified by luciferase activity assay using reporters with wild-type miR-30e and its seed sequence mutant constructs and Western blotting assay. In vivo experiment showed that miR-30e overexpression significantly inhibited tumor growth and decreased RPS6KB1 expression in xenografts. In EC, high expression of RPS6KB1 in tumor tissues indicated poor prognosis of patients with less survival rate. High levels of RPS6KB1 and low levels of miR-30e closely correlated poor survival of patients with several other types of cancer. These findings show that miR-30e and its target RPS6KB1 are important in cancer development and clinical outcomes, and miR-30e/RPS6KB1 is a potential future therapeutic pathway for EC intervention.

Lingguizhugan decoction is commonly used to treat metabolic syndrome; however, its curative effect on hypertension is still unclear. Our study aimed to evaluate the clinical efficacy and safety of Lingguizhugan decoction combined with western medicine in the treatment of hypertension.We searched 7 electronic databases for relevant studies and full-text articles involved in the evaluation of clinical effects difference between Lingguizhugan decoction combined with western medicine and western medicine alone. All included articles were quality assessed and data analysis was conducted with Review Manager (5.4). Sensitivity analysis was performed, and the results were visualized by means of forest and funnel plots. Results were expressed as risk ratio (RR) or mean difference (MD), together with their 95% confidence intervals (CIs).In total, 7 studies eventually met our inclusion criteria. The results showed that Lingguizhugan decoction combined with western medicine had a better improvement in decrease systolic blood pressure (SBP) (MD =12.33 mmHg; 95% CI: 3.37 to 21.28; P=0.007) and diastolic blood pressure (DBP) (MD =7.42 mmHg; 95% CI: 1.89 to 12.95; P=0.009) than western medicine alone, it also had a higher effective ratio (RR =1.20; 95% CI: 1.11 to 1.31; P0.0001) and lower adverse reactions (RR =0.51; 95% CI: 0.30 to 0.86; P=0.01). The results were robust and no obvious publication bias was observed in this study.Our research supported that Lingguizhugan decoction combined with western medicine can effectively reduce patients' blood pressure and improve their clinical symptoms. Because of the limitation in the quantity and quality of the included studies, further large sample and multi center follow-up controlled trials should be carried out to validate our conclusions.

Urinary tract infection (UTI) is a common infectious disease. Urinary tract pathogenic Escherichia coli (UPEC) is the main cause of UTIs. At present, antibiotics are mainly used for the treatment of UTIs. However, with the increase of drug resistance, the course of the disease is prolonged. Therefore, identifying the receptors and signal pathways of host cells and tissues will further our understanding of the pathogenesis of UTIs and help in the development of new drug treatments. We used two public microarray datasets (GSE43790, GSE124917) in the Gene Expression Omnibus (GEO) database to identify differentially expressed genes (DEGs) between UTI and normal cell samples. A functional analysis based on Gene Ontology (GO) data, a pathway enrichment analysis based on Kyoto Encyclopedia of Genes and Genomes (KEGG) data and a protein-protein interaction analysis identified the main potential biomarkers and verified them in animal tissues. A total of 147 up-regulated genes and 40 down-regulated genes were identified. GO enrichment analysis showed that these functional changes relate to the terms response to lipopolysaccharide, regulation of cytokine production, and regulation of the inflammatory response. KEGG analysis indicated that urinary tract infections likely involve the TNF-αsignaling pathways. The 20 hub genes were selected from the protein-protein interaction network, and the highly significant hub genes were verified by animal experiments. Our findings provide potential targets for exploring new treatments for urinary tract infections. After a comprehensive analysis of the GEO database, these results may facilitate development of new diagnosis and treatment strategies for urinary tract infections.

Recent studies have demonstrated the pivotal role played by microRNAs (miRNAs) in the etiopathogenesis of intervertebral disc degeneration (IDD). The study of miRNA intervention in IDD models may promote the advancement of miRNA-based therapeutic strategies. The aim of the current study was to investigate whether intradiscal delivery of miRNA can attenuate IDD development. Our results showed that miR-338-3p expression was significantly increased in the nucleus pulposus (NP) of patients with IDD. Moreover, there was a statistically significant positive correlation between the expression level of miR-338-3p and the severity of IDD. Our functional studies showed that miR-338-3p significantly influenced the expression of extracellular matrix synthesis genes, as well as the proliferation and apoptosis of NP cells. Mechanistically, miR-338-3p aggravated IDD progression by directly targeting SIRT6, a negative regulator of the MAPK/ERK pathway. Intradiscal injection of antagomir-338-3p significantly decelerated IDD development in mouse models. Our study is the first to identify miR-338-3p as a mediator of IDD and thus may be a promising target for rescuing IDD., Spine disease: how to halt disc degradation Development of intervertebral disc degeneration (IDD) is driven by a microRNA, a short noncoding segment of genetic material, called miR-338-3p, and blocking it may offer a path to better treatments. In IDD, a common spine disorder, the cushioning discs between vertebrae degenerate, leading to pain and loss of mobility. Current treatments address symptoms, not the root causes. Micro-RNAs have emerged as key contributors to skeletal disorders, and Qingjun Wei and Hua Jiang at Guangxi Medical University, Nanning, China, investigated their role in IDD. Screening of microRNAs in IDD patients showed that miR-338-3p levels were significantly elevated and correlated with IDD severity. Inhibiting miR-338-3p in cultured disc cells boosted their proliferation, and administering the inhibitor to a mouse model suppressed IDD development. These results may help in identifying new treatments for this common and debilitating condition.

To understand the relationship between the inhibition of Toll-Like Receptor-4 (TLR4) expression levels and diabetic myocardial injury, studies on TLR4 and diabetic myocardial injury in the China National Knowledge Internet (CNKI), WanFang database, VIP Database, PubMed, The Cochrane Library, Web of Science, and other databases were explored (retrieval details: November 2020). A meta-analysis of the selected literature was performed using the RevMan 5.4 software to detect publication bias using funnel plots and conduct a sensitivity analysis. Nine publications were finally included in this study, of which six included data on Heart Weight/Body Weight (HW/BW) indexes, and five included data on Left Ventricular Systolic Pressure (LVSP) and Left Ventricular End-Diastolic Pressure (LVEDP) indices. The meta-analysis showed that HW/BW was significantly reduced after the suppression of TLR4 expression (Standardized Mean Difference [SMD = 1.9], 95% CI between 0.59 and 3.21, p = 0.004), LVSP was significantly improved (SMD = -2.39, 95% CI between -4.32 and -0.46, p = 0.02), and LVEDP was significantly reduced (SMD = 2.88, 95% CI between 1.05 and 4.71, p = 0.002). The TLR4 signaling pathway plays an essential role in the pathogenesis of Diabetic Cardiomyopathy (DCM). Inhibition of TLR4 expression can improve the degree of cardiac impairment. TLR4 may become a new target for the treatment of DCM, and the use of TLR4 inhibitors may prove to be a novel strategy for therapeutic research.

BackgroundMetabolic disturbances and immune alterations caused by diabetes are not just bystanders of HPV infection, but the conclusion that diabetes increases the risk of HPV infection requires more clinical epidemiological evidence to confirm. Our aim was to evaluate the association of diabetes with HPV infection risk in female patients aged over 50 years in the cervical clinic.MethodsWe conducted a cross-sectional study of 6402 women aged over 50 years in the cervical clinic between May 2019 and March 2022 from China’s largest academic woman’s hospital. The quantitative-effect relationship between diabetes and HPV infection was observed by dose-response graph. Segmented multivariate logistic regression analysis was conducted to estimate the relative risk of HPV infection in diabetes patients. Multivariable predicted marginal proportions from logistic regression models were used to compute adjusted risk ratios.ResultsThere is a nonlinear relationship between HbA1c and the risk of HPV infection. When the HbA1c exceeds 5.7%, there is a saturation effect. After adjustment for confounders, the risk ratio for HPV infection in women with prediabetes was 1.09 (95% CI: 1.00-1.18) compared with women with HbA1c ConclusionsDiabetes and prediabetes are at increased risk of coinfection with HPV in female patients aged over 50 years in the cervical clinic.

Diet quality during reproduction is crucial to maternal and infant health. However, the association between dietary diversity and bone health of pregnant women remains unclear. We aimed to evaluate the dietary quality of Chinese urban gravidas using the dietary diversity score (DDS), and to explore the relationship of the DDS with micronutrient adequacy and bone health. In this cross-sectional study, we analyzed data from 775 pregnant women aged 18 years or older in urban China. Dietary diversity was assessed using the Minimum Dietary Diversity for Women (MDD-W) indicator. A 24-h dietary recall was used to collect diet data and to calculate the MDD-W and the nutrient intake. Bone health was measured using quantitative ultrasound and assessed by the speed of sound (SOS). Pearson’s correlation coefficients between the DDS and the nutrient adequacy ratio (NAR) were calculated. A multivariable linear regression model was used to estimate the effect size of the DDS on the SOS. The mean DDS was 6.61 ± 1.53 points and 91.0% of participants reported the consumption of five or more food groups. Women in the diverse diet subgroup (DDS ≥ 7 points) were more likely to consume all kinds of food except starchy staples and had higher NARs. Pearson’s correlation coefficients between the DDS and the NAR ranged from 0.161 to 0.484. For participants in the second trimester, those with a diverse diet had a higher SOS. A multivariable linear regression analysis showed that the DDS was positively and significantly associated with the SOS (β = 17.18, 95% CI = 5.97–28.39, p = 0.003), but this was not the case for women in the first and third trimesters. Urban Chinese women had good dietary diversity during pregnancy. A higher dietary diversity was associated with a higher NAR. From the point of view of bone, a diverse diet was positively correlated with better bone status, suggesting the importance of improving diet diversity for pregnant women, especially from mid-pregnancy.

Background Gastric cancer is a major public health problem worldwide. Social media has affected public’s daily lives in ways no one ever thought possible. Both TikoTok and its Chinese version Douyin are the most popular short video posting platform. This study aimed to evaluate the quality, accuracy, and completeness of videos for gastric cancer on TikTok and Douyin. Methods The terms “gastric cancer” was searched on TikTok in both English and Japanese, and on Douyin in Chinese. The first 100 videos in three languages (website’s default setting) were checked. QUality Evaluation Scoring Tool (QUEST) and DISCERN as the instrument for assessing the quality of the information in each video. Content was analysed under six categories (aetiology, anatomy, symptoms, preventions, treatments, and prognosis). The educational value and completeness were evaluated with a checklist developed by the researchers. Results A total of 78 videos in English, 63 in Japanese, and 99 in Chinese were analyzed. The types of sources were as follows: 6.4% in English, 4.8% in Japanese, and 57.6% in Chinese for health professionals; 93.6% in English, 95.2% in Japanese, and 3.0% in Chinese for private users; none in English and Japanese, but 39.4% in Chinese for other sources. In all, 20.5% in English, 17.5% in Japanese, and 93.9% in Chinese of videos had useful information about gastric cancer. Among the useful videos, the videos published in Chinese had the highest QUEST(p Conclusions TikTok in English and Japanese might not fully meet the gastric cancer information needs of public, but Douyin in Chinese was the opposite.

Background The purpose of this study was to introduce a modified lateral approach for combined radical resection of buccal squamous cell carcinoma (BSCC) and evaluate its surgical, oncological, functional, and aesthetic outcomes in comparison with the conventional lower-lip splitting approach. Methods This single-center study retrospectively reviewed 80 patients with BSCC, of which 37 underwent the lateral approach and 43 underwent the conventional approach. Surgical, functional, oncological, and aesthetic evaluations, as well as follow-ups, were recorded and compared. Results Compared to the conventional approach group, the lateral approach group had a longer surgical time (P = 0.000), but there was no significant difference in other surgical and oncological parameters. Moreover, the scar in the head and neck had a significantly discreet appearance in the lateral approach group, whose satisfaction was better than those in the conventional approach group (P = 0.000). Other oral function parameters, postoperative mouth-opening, and 3-year survival rate were not significantly different between the two groups. Conclusion The lateral approach could provide superior aesthetic results while maintaining equal surgical, functional, and oncological outcomes compared to the conventional approach for radical resection of BSCC.

BackgroundDiabetes causes metabolic disorders and immune changes that may be potential triggers of cervical cancer. Therefore, diabetes is not a “bystander” to cervical cancer. However, the conclusion that diabetes promotes cervical cancer lacks clinical epidemiological evidence, and the reported potential association between diabetes and cervical cancer is controversial.MethodsWe conducted an explorative cross-sectional study of 791 women with cytological HGSIL and HR-HPV, who attended the cervical clinic of the largest academic women’s hospital in China from May 2019 to March 2022. After cervical screening, patients who were requiring colposcopy were tested for HbA1c. HbA1c level of 6.5% or higher defines diabetes and HbA1c level of 5.7%-6.4% was defined as prediabetes. The relationship between diabetes and cervical cancer was observed by a dose-response graph. Subgroup analysis and multivariate logistic regression analysis were conducted to estimate the associations between diabetes and cervical cancer.ResultsAmong HGSIL patients with high-risk HPV infection, compared with women with HbA1c ConclusionsIn patients with HR-HPV combined with HGSIL, diabetes and prediabetes are associated with cervical cancer.

Background: Antibodies and derivative drugs targeting immune checkpoints have been approved for the treatment of several malignancies, but there are fewer responses in patients with pancreatic cancer. Here, we designed a nanobody molecule with bi-targeting on PD-L1 and CXCR4, as both targets are overexpressed in many cancer cells and play important roles in tumorigenesis. We characterized the biochemical and anti-tumour activities of the bispecific nanobodies in vitro and in vivo. Methods: A nanobody molecule was designed and constructed. The nanobody sequences targeting PD-L1 and CXCR4 were linked by the (G4S)3 flexible peptide to construct the anti-PD-L1/CXCR4 bispecific nanobody. The bispecific nanobody was expressed in E. coli cells and purified by affinity chromatography. The purified nanobody was biochemically characterized by mass spectrometry, Western blotting and flow cytometry to confirm the molecule and its association with both PD-L1 and CXCR4. The biological function of the nanobody and its anti-tumour effects were examined by an in vitro tumour cell-killing assay and in vivo tumour inhibition in mouse xenograft models. Results: A novel anti-PD-L1/CXCR4 bispecific nanobody was designed, constructed and characterized. The molecule specifically bound to two targets on the surface of human cancer cells and inhibited CXCL12-induced Jurkat cell migration. The bispecific nanobody increased the level of IFN-γ secreted by T-cell activation. The cytotoxicity of human peripheral blood mononuclear cells (hPBMCs) against pancreatic cancer cells was enhanced by the molecule in combination with IL-2. In a human pancreatic cancer xenograft model, the anti-PD-L1/CXCR4 nanobody markedly inhibited tumour growth and was superior to the combo-treatment by anti-PD-L1 nanobody and anti-CXCR4 nanobody or treatment with atezolizumab as a positive control. Immunofluorescence and immunohistochemical staining of xenograft tumours showed that the anti-tumour effects were associated with the inhibition of angiogenesis and the infiltration of immune cells. Conclusion: These results clearly revealed that the anti-PD-L1/CXCR4 bispecific nanobody exerted anti-tumour efficacy in vitro and inhibited tumour growth in vivo. This agent can be further developed as a therapeutic reagent to treat human pancreatic cancer by simultaneously blocking two critical targets.

Unfolded protein response (UPR) is the mechanism by which cells control endoplasmic reticulum (ER) protein homeostasis. ER proteostasis is essential to adapt to cell proliferation and regeneration in development and tumorigenesis, but mechanisms linking UPR, growth control, and cancer progression remain unclear. Here, we report that the Ire1/Xbp1s pathway has surprisingly oncogenic and tumor-suppressive roles in a context-dependent manner. Activation of Ire1/Xbp1s up-regulates their downstream target Bip, which sequesters Yorkie (Yki), a Hippo pathway transducer, in the cytoplasm to restrict Yki transcriptional output. This regulation provides an endogenous defensive mechanism in organ size control, intestinal homeostasis, and regeneration. Unexpectedly, Xbp1 ablation promotes tumor overgrowth but suppresses invasiveness in a Drosophila cancer model. Mechanistically, hyperactivated Ire1/Xbp1s signaling in turn induces JNK-dependent developmental and oncogenic cell migration and epithelial-mesenchymal transition (EMT) via repression of Yki. In humans, a negative correlation between XBP1 and YAP (Yki ortholog) target gene expression specifically exists in triple-negative breast cancers (TNBCs), and those with high XBP1 or HSPA5 (Bip ortholog) expression have better clinical outcomes. In human TNBC cell lines and xenograft models, ectopic XBP1s or HSPA5 expression alleviates tumor growth but aggravates cell migration and invasion. These findings uncover a conserved crosstalk between the Ire1/Xbp1s and Hippo signaling pathways under physiological settings, as well as a crucial role of Bip-Yki interaction in tumorigenesis that is shared from Drosophila to humans.

To investigate the expression of ROBO3 in pediatric AML patients and explore its function on cell proliferation and apoptosis.The expression of ROBO3 in pediatric AML patients at different treatment stage was detected by real-time quantitative polymerase chain reaction (RT-qPCR). The relationship between the expression of ROBO3 and clinic pathological characteristics in newly diagnosed pediatric AML patients was analyzed. Moreover, the effects of ROBO3 on the proliferation and apoptosis of AML cell lines HL-60 and THP-1 were estimated by using CCK-8 and flow cytometry after transfection with ROBO3 siRNA.It was found that ROBO3 expression was significantly increased in most of newly diagnosed pediatric AML patients, especially in non-M3 subtype, younger patients (10 years old), and high risk group, compared to corresponding controls. Furthermore, the expression level of ROBO3 was sharply decreased in patients who achieved complete remission. Targeting ROBO3 significantly inhibited AML cell proliferation, as well as increased apoptosis by ROBO3 siRNA transfection in vitro.ROBO3 is differentially expressed within distinct subtypes of the pediatric AML patients, which suggested that ROBO3 may be a potential biomarker and a new therapeutic target for pediatric AML.ROBO3在儿童急性髓系白血病患者中的表达及其对细胞增殖和凋亡的影响.研究ROBO3在儿童急性髓系白血病（AML）患者中的表达及其对AML细胞增殖和凋亡的影响。.采用荧光定量PCR法检测不同治疗阶段的儿童AML患者骨髓中ROBO3的表达，分析初诊患儿ROBO3表达量与临床特征的关系。同时采用电转染的方法靶向干扰ROBO3表达，应用 CCK-8 法检测其对AML细胞系（HL-60和THP-1）增殖的影响，流式细胞术检测其对凋亡的作用。.与健康对照组相比，ROBO3在初诊儿童AML患者中显著高表达，尤其是在非M3型、年龄偏小的患者（10岁）及高危组中高表达。而且与初发组相比，治疗后完全缓解组ROBO3 mRNA的表达水平显著下降。靶向ROBO3可以有效抑制AML细胞的增殖，并促进细胞凋亡。.ROBO3在儿童AML患者中差异表达，很可能是儿童AML潜在的标志物及新靶点。.

Gut microbiome is an important regulator of hepatic inflammation, detoxification, and immunity, and contributes to the carcinogenesis of liver cancer. Intratumoral bacteria are supposed to be closer to the tumor cells, forming a microenvironment that may be relevant to the pathological process of hepatocellular carcinoma (HCC).

To optimize the pretreatment method of colorectal cancer tissue samples for metabolomics research based on solid-phase nuclear magnetic resonance (NMR).The mucosal tissues of colorectal cancer were classified into five groups with a volume of 0.2 cm*0.2 cm*0.2 cm. The pretreatment methods for each group were as follows: I. Preservation with liquid nitrogen alone. Samples were also treated with liquid nitrogen for 10 (II), 20 (III), and 30 min (IV), respectively, immediately after isolation and then transferred to a -80℃ refrigerator; V. Only -80℃ refrigerator storage. No more than 30 minutes should pass between isolation and pretreatment of tumor samples. The tissue sample testing process was carried out on Bruker AVII-600 NMR Spectrometer. NMR signals were collected and analysed using partial least-squares discrimination analysis (PLS-DA) to explore the effects of different pretreatment methods on the metabolic changes of samples.The levels of pelargonic acid, stearic acid, D-Ribose, heptadecanoic acid, pyruvic acid, succinate, sarcosine, glycine, creatine, and L-lactate in the group I (only liquid nitrogen) were significantly lower than the other groups (p0.05); the content of glycerophosphocholine in the group I (only liquid nitrogen) was lower than that in the other groups (p=0.055). These indicated that the glucose and choline phospholipid metabolism levels of the liquid nitrogen group were significantly lower than those of the other four groups.Liquid nitrogen storage can stop the metabolic process of glucose and choline phospholipid in colorectal cancer tissue samples in vitro, thus maintaining the metabolic state of tissue samples in vivo as much as possible.

To investigate whether rescue in vitro maturation (R-IVM) improves the reproductive outcomes among women undergoing intracytoplasmic sperm injection (ICSI) after one oocyte retrieved cycle.Between January 2019 and December 2020, 2602 women who underwent ICSI in the Reproductive Medicine Center of Tongji Hospital, Wuhan, China, were included in our retrospective cohort study. There were 2112 women undergoing only ICSI and 490 women with R-IVM followed by ICSI. The intermediate reproductive outcomes and pregnancy outcomes were assessed, including the number of normally fertilized embryos, number of cleaved embryos, number of good-quality embryos, number of day-3 available embryos, number of embryos cultured past day-3, number of blastocysts, number of available blastocysts, biochemical pregnancy, miscarriage, clinical pregnancy and live birth. The perinatal outcomes were also assessed, including preterm birth and birth weight. The abovementioned outcomes were also calculated for in vivo matured and R-IVM oocytes separately in women undergoing ICSI with R-IVM group.Compared with the women who underwent only ICSI, those who underwent ICSI with R-IVM had higher numbers of MII oocytes, normally fertilized embryos, cleaved embryos, day-3 available embryos, embryos cultured past day-3, and higher oocyte maturation rate, available embryo rate than women undergoing only ICSI. Additionally, we found that women undergoing ICSI with R-IVM had an increased chance of clinical pregnancy (adjusted OR=1.50, 95% CI: 1.17-1.93) and cumulative live birth (adjusted OR=1.35, 95% CI: 1.07-1.71). After propensity score matching (PSM), the cumulative live birth rate was 60.1% for women undergoing ICSI with R-IVM versus 54.9% for women undergoing only ICSI (OR=1.24, 95% CI: 0.94-1.63). The reproductive outcomes were also significantly different when calculated for in vivo matured and R-IVM oocytes separately in women undergoing ICSI with R-IVM group. All live births from R-IVM embryos were healthy and without malformations or complications.R-IVM may improve the reproductive outcomes of women undergoing ICSI. It may also provide a reference for the safety of R-IVM. This study maybe support a routine application of R-IVM among patients who intend to undergo ICSI.

Circular RNA (circRNA/circ) profiles have been suggested to be involved in the prognosis of several types of solid tumors and hematological malignancies, including multiple myeloma (MM). Therefore, the aim of the present study was to comprehensively explore the involvement of circRNA profiles in MM prognosis. A total of 60 patients with MM that underwent bortezomib‑based induction therapy were enrolled. Next, eight patients with complete response (CR) and eight with no response (NR) were randomly selected to detect their circRNA profiles in bone marrow plasma cells (BMPCs) by microarray. Next, 10 candidate circRNAs were verified via reverse transcription‑quantitative PCR (RT‑qPCR) in the BMPCs of 60 patients with MM. Finally, the molecular mechanism of circ_0026652 knockdown underlying the regulation of chemosensitivity to bortezomib was assessed. Microarray showed that 79 circRNAs were upregulated and 167 were downregulated in CR compared with NR cases, which were found to be enriched in carcinogenic and chemoresistance‑related pathways (Wnt, mTOR and MAPK pathways). RT‑qPCR showed that 8/10 circRNAs (circ_0026652, circ_0068708, circ_0088128, circ_0001566, circ_0031113, circ_0083587, circ_0005552 and circ_0007171) were associated with treatment response [CR or objective response rate (ORR)] and 5/10 circRNAs (circ_0026652, circ_0068708, circ_0001566, circ_0031113 and circ_0005552) were associated with progression‑free survival (PFS) or overall survival (OS). Of note, circ_0026652 was a key prognostic marker simultaneously associated with CR, ORR, PFS and OS. Cellular experiments showed that circ_0026652 knockdown enhanced chemosensitivity to bortezomib through the microRNA (miR)‑608‑mediated Wnt/β‑catenin pathway in U266 and RPIM‑8226 cells. In conclusion, dysregulated circRNA profiles were closely associated with MM prognosis, with circ_0026652 being linked to bortezomib‑based treatment response and survival through the miR‑608‑mediated Wnt/β‑catenin pathway.

Objectives We aimed to determine the prevalence of urinary incontinence (UI) during the peri- and postpartum period in women from Nanjing, China, and estimate its risk factors. Methods From January to December 2018, a total of 6500 postpartum women were enrolled and asked to complete the questionnaires. Of these, 6370 (98%) women returned the questionnaires with valid responses. Additional data were collected, including age, height, weight, gestation time and parity, and neonatal weight. The International Consultation on Incontinence Questionnaire-Urinary Incontinence Short Form was used. Surface electromyography (sEMG) and a biofeedback training system were used as a testing platform, and PESEMG values were obtained. Results The prevalence of UI during pregnancy and at 6 weeks postpartum in women was 29.76% and 12.50%, respectively. The prevalence of stress UI (SUI), urge UI (UUI), mixed UI (MUI), and other types of UI that developed during pregnancy was 25.48%, 1.66%, 1.65%, and 0.97%, respectively. The prevalence of SUI, UUI, MUI, and other types of UI at 6 weeks postpartum was 8.49%, 2.07%, 1.16%, and 0.77%, respectively. Multivariate analysis showed that advanced age, greater postpartum body mass index (BMI), macrosomia, multiparity, and vaginal delivery were risk factors of postpartum UI. Women with mild degree of UI in pregnancy, those who had undergone cesarean section, and those without UI before pregnancy were relieved from UI at 6 weeks postpartum. Conclusions The rate of UI in peri- and postpartum women from Nanjing is consistent across China. The most common type of UI was SUI, with many risk factors affecting its occurrence. Advanced age, greater postpartum BMI, multiparity, macrosomia, and vaginal delivery might be the main risk factors of UI in postpartum women.

Abstract Peritoneal metastasis is a common issue in the progression of high-grade serous ovarian cancers (HGSOCs), yet the underlying mechanism remains unconfirmed. We demonstrated that ZEB2, the transcription factor of epithelial–mesenchymal transition (EMT), was upregulated in ascites cells from HGSOC patients and in CD133+ cancer stem-like cells (CSLCs) from epithelial ovarian cancer (EOC) cell lines. SiRNA-mediated knockdown of ZEB2 in EOC cells decreased the percentage of CSLCs and reduced the colony forming potential, cell invasion capacity and expression of pluripotent genes Oct4 and Nanog. Inhibition of ZEB2 also induced cellular apoptosis and impacted the tumorigenicity of ovarian CSLCs. The mesenchymal markers N-cadherin and vimentin were downregulated, while the epithelial marker E-cadherin was upregulated after ZEB2 knockdown. MiR-200a, a molecule that downregulates ZEB2, had the opposite effect of ZEB2 expression in EOC-CSLCs. A retrospective study of 98 HGSOC patients on the relationship of ascites volume, pelvic and abdominal metastasis, International Federation of Gynecology and Obstetrics (FIGO) stage and the malignant involvement of abdominal organs and lymph nodes was performed. Patients with high expression of ZEB2 in tumour tissues had a higher metastasis rate and a poorer prognosis than those with low expression. The parameters of ZEB2 expression and ascites volume were strongly linked with the prognostic outcome of HGSOC patients and had higher hazard ratios. These findings illustrated that ZEB2 facilitates the invasive metastasis of EOC-CSLCs and can predict peritoneal metastasis and a poor prognosis in HGSOC patients.

Introduction Clinicians increasingly perform laparoscopic surgery for intrahepatic cholangiocarcinoma (ICC). However, this surgery can be difficult in patients with advanced-stage ICC because of the complicated procedures and difficulty in achieving high-quality results. We compared the effects of a three-step optimized procedure with a traditional procedure for patients with advanced-stage ICC. Methods Forty-two patients with advanced-stage ICC who received optimized laparoscopic hemihepatectomy with lymph node dissection (LND, optimized group) and 84 propensity score-matched patients who received traditional laparoscopic hemihepatectomy plus LND (traditional group) were analyzed. Surgical quality, disease-free survival (DFS), and overall survival (OS) were compared. Results The optimized group had a lower surgical bleeding score (P = 0.038) and a higher surgeon satisfaction score (P = 0.001). Blood loss during hepatectomy was less in the optimized group (190 vs. 295 mL, P vs. 8.0, P vs. 5.0, P vs. 77.4%, P = 0.149). The optimized group had longer median DFS (9.0 vs. 7.0 months, P = 0.018) and median OS (15.0 vs. 13.0 months, P = 0.046). In addition, the optimized group also had a shorter total operation time (P = 0.001), shorter liver resection time (P = 0.001), shorter LND time (P P vs. 36.9%, P = 0.009). Conclusions Our optimization of a three-step laparoscopic procedure for advanced ICC was feasible, improved the quality of liver resection and LND, prolonged survival, and led to better intraoperative and postoperative outcomes.

As the predominant stroma cells of tumor microenvironment (TME), cancer associated fibroblasts (CAFs) are robust tumor player of different malignancies. However, less is known about the regulatory mechanism of CAFs on promoting progression of ovarian cancer (OvCA). In the present study, the conditioned medium of primary CAFs (CAF-CM) from OvCA was used to culture cell lines of epithelial ovarian cancer (EOC), and showed a potent role in promoting proliferation, migration and invasion of cancer cells. Mass spectrum (MS) analysis identified that Collapsin response mediator protein-2 (CRMP2), a microtubule-associated protein involved in diverse malignancies, derived from CAFs was a key regulator responsible for mediating these cell events of OvCA. In vitro study using recombinant CRMP2 (r-CRMP2) revealed that the protein promoted proliferation, invasion, and migration of OvCA cells through activation of hypoxia-inducible factor (HIF)-1α-glycolysis signaling pathway. The CRMP2 was abundantly expressed in OvCA, with a well correlation with metastasis and poor prognosis, as analyzed from 118 patients’ samples. Inhibition of the CRMP2 derived from CAFs by neutralizing antibodies significantly attenuated the tumor size, weights, and metastatic foci numbers of mice in vivo. Our finding has provided a novel therapeutic clue for OvCA based on TME.

This study describes an 8-year-old boy with a C2 fracture and dislocation with a left C2-C3 articular process interlocking and spinal cord injury who underwent open reduction and internal fixation using the posterior cervical approach and achieved satisfactory results.An 8-year-old boy underwent an emergency transfer from a previous hospital after a car accident.Axial fracture and dislocation with spinal cord injury (American Spinal Injury Association grade C), traumatic shock, brain contusion, intracranial hemorrhage, mandibular fracture, pulmonary contusion and hemorrhage, left vertebral artery stenosis, and multiple fractures throughout the body. Radiological examination revealed a fracture of the lower edge of the C2 vertebral body, fourth-degree anterior spondylolisthesis of the C2 vertebral body, interlocking of the left C2-C3 articular processes, widening of the C2-C3 vertebral space, and occlusion of the V1 and 2 segments of the left vertebral artery.The boy was immediately intubated and transferred to the pediatric intensive care unit for rescue treatment. However, the reduction was unsuccessful with 2 weeks of cranial traction. Thus, an open reduction was performed under general anesthesia. One month after the surgery, the boy was discharged from the hospital on foot after rehabilitation treatment.The boy was discharged from the hospital 1 month after surgery. At the 8-month follow-up, a radiological examination showed that the corrected C2 vertebral body fracture and dislocation were satisfactorily reduced, and the spinal cord was adequately decompressed. The internal fixation position was also good, and the spinal sequence had recovered well. In summary, except for the muscle strength of the right upper limb, which was slightly worse, the other clinical symptoms were significantly improved.In treating cervical fracture and dislocation with unilateral facet lock, the posterior open reduction of pedicle screw and lateral mass screw internal fixation achieved satisfactory results. Consequently, treating complex cervical spine injuries in children requires an accurate diagnosis and careful treatment strategy.

To explore the risk factors of abdominal aortic enlargement (AAE) after thoracic endovascular aortic repair using two-stent graft implantation (TEVAR-TSI) for Stanford type B aortic dissection.The clinical and imaging data of patients who underwent TEVAR-TSI for Stanford type B aortic dissection in the First Affiliated Hospital of Hebei North University from January 2013 through September 2020 were retrospectively collected and analyzed. CT angiography (CTA) scans were performed before the procedure. Follow-up CTA scans were scheduled and performed in 1, 3, 6, and 12 months after the procedure and annually thereafter. The primary outcome was AAE. The risk factors of AAE after TEVAR-TSI were selected and survival analysis and multivariate logistic regression were conducted accordingly.A total of 146 patients were regularly followed up at our hospital, with the median followup time of the entire cohort being 48 months (ranging from 12 to 84 months). During the followup period after TEVAR-TSI, the incidence of AAE was 19.9% (29/146). A total of 29 patients developed AAE (the AAE group), while 117 patients did not develop AAE (the non-AAE group). There were a total of 27 deaths, including 13 in the non-AAE group versus 14 in the AAE group. Distal aortic reoperation was performed on 10 patients, including 4 in the non-AAE group versus 6 in the AAE group. The cumulative long-term survival and freedom from distal aortic reoperation of the non-AAE group were both significantly better those of the AAE group (The prognosis of patients who developed AAE after TEVAR-TSI was not good. During followup visits, as precautions against the development of AAE, close attention should be paid to partial thrombosis of the false lumen, cumulative diameter of residual intimal tear above the level of the lowest renal arteries, and cumulative diameter of residual intimal tear below the level of the lowest renal arteries.

Botulinum toxin A(BoNT/A) is a neurotoxin produced by the bacteria Clostridium botulinum, which can cause serious food poisoning and is recognized as a potential biological warfare agent. BoNT/A is does not degrade easily and can remain in the complex matrix for a long time. Meanwhile, the poisonous dose of botulinum toxin exceptionally low and intravenous human lethal doses estimated at 1-3 ng/kg. Therefore, sensitive and accurate detection methods suitable for testing a wide range of complex samples are urgently needed. To this end, the “amplified luminescent proximity homogeneous assay linked immunosorbent assay” (AlphaLISA) was established for the detection of BoNT/A and its detection efficacy in plasma, beverage, food, and other complex samples was evaluated. The results showed that this method can very effectively resist matrix interference. The detection time is rapid, reaching a detection limit for all samples of up to 0.1 ng/mL in only 30 min. BoNT/A can also be accurately detected in vomit samples of patients with clinical food poisoning. This study demonstrates that AlphaLISA is an effective tool for the detection of BoNT/A in complex samples and can potentially be developed for commercial use in the future.

Background LCAR-B38M is a chimeric antigen receptor T cell product with two binding domains targeting B cell maturation antigen. Our previous reports showed a remarkable efficacy of LCAR-B38M in patients with relapsed/refractory multiple myeloma (RRMM) at a median follow-up of 2 years. Here, we report long-term safety and efficacy data from a median follow-up of 4 years. Methods LEGEND-2 was a phase 1, single-arm, open-label study conducted in four registered sites in China. Seventy-four participants with RRMM received LCAR-B38M treatment. Lymphodepletion was performed using cyclophosphamide or cyclophosphamide plus fludarabine. LCAR-B38M, at a median dose of 0.513 × 106 cells/kg, was intravenously administered either in three split infusions or in a single infusion. The primary objective was the safety of LCAR-B38M, and the secondary objective was efficacy. Results As of May 25, 2021, the median follow-up was 47.8 months. All patients experienced ≥ 1 adverse events (AEs). Grade ≥ 3 AEs were observed in 45/74 (60.8%) patients. Cytokine release syndrome (CRS) occurred in 68/74 (91.9%) cases; 7 (9.5%) had grade ≥ 3 CRS. One patient experienced grade 1 central nervous system toxicity. The overall response rate was 87.8%. Fifty-four out of 74 (73.0%) patients achieved complete response. The median progression-free survival was 18.0 months, and the median overall survival for all patients was not reached. The median duration of response was 23.3 months. Four patients experienced viral infection more than 6 months post-infusion, and four patients developed second primary non-hematological malignancies at a median time of 11.5 months post-CAR-T cell transfer. Conclusions The 4-year follow-up data of LCAR-B38M therapy demonstrated a favorable long-term safety profile and a durable response in patients with RRMM.

Ginseng (Panax ginseng C. A. Meyer), a perennial herb, possesses immunostimulatory, anticarcinogenic, antiemetic, and antioxidative biological activities. In recent years, more and more people have paid attention to the extraction methods and quality evaluation of ginseng. China, the United States, Europe, Japan, and Korea have all had the quality standards and content determination methods of ginseng. The different treatment methods are adopted before the determination of ginseng samples and the content limits of the index components, such as ginsenoside Rb1, ginsenoside Rg1, and ginsenoside Re exist differences. The similarities and differences of ginseng content detection methods in pharmacopoeias of different countries have been analyzed by a research group, but the comparison of the effects of different methods on the ginsenoside content and structural transformation has not been reported. In this paper, ginsenosides in ginseng were extracted according to four national pharmacopoeias and analyzed quantitatively and qualitatively by UPLC-Q-Exactive-MS and HPLC-UV. It was illustrated that the pretreatment method has a significant influence on the content determination of ginseng. The yield of rare saponins was increased by heating concluded from both the qualitative and quantitative comparison. Finally, a simple and feasible extraction method was optimized by response surface method at room temperature. The analysis of the preparation method and process optimization of the four pharmacopoeias can provide important reference information for the revision of ginseng standards.
