Objective: To reach consensus on the diagnostic criteria of syndrome of dampness obstruction in idiopathic membranous nephropathy (IMN) patients by literature research and expert investigation (interviews and a Delphi method)., Methods: Our study was consistent with T/CACM 1336-2020. We searched the monographs and references published in the past 40 years (1983-2022), and established the diagnostic criteria pool of water-dampness syndrome and dampness-turbidity syndrome in Traditional Chinese Medicine (TCM) based on literature by using frequency statistics and correlation analysis. Expert investigation (interview method and two rounds of Delphi method) was used to form the diagnostic criteria of water-dampness syndrome and dampness-turbidity syndrome of idiopathic membranous nephropathy. Clinical diagnostic test research was carried out, and compared with "Diagnostic Criteria for dampness syndrome" (T/CACM 1454-2023) to evaluate the authenticity, reliability and clinical application value of the standard., Results: A total of 122 relevant guides, standards, monographs and documents were included through searching books and Chinese databases. Four experts were interviewed and two rounds of delphi method (75 experts nationwide) were carried out. The experts' opinions are relatively concentrated and the differences are small. Based on the weight of each index, the diagnostic criteria indexes of water-dampness syndrome and dampness-turbidity syndrome were selected. After discussion by the core group members, the diagnostic model of "necessary symptoms and optional symptoms" was established, and the final diagnostic criteria of water-dampness syndrome and dampness-turbidity syndrome were established. One hundred and ninety-one inpatients and outpatients of Guangdong Provincial Hospital of Chinese Medicine from January 2021 to February 2023 were included in Diagnostic test study. There was no statistical difference in gender, age and course of disease ( P > 0.05). The sensitivity and specificity of the trial standard were 90.34% and 73.33% respectively, while the sensitivity and specificity of T/CACM 1454-2023 were 99.43% and 6.67%, respectively., Conclusions: The consensus-based diagnostic criteria for IMN can be widely incorporated in TCM. A further clinical study will be conducted to analyze the diagnosis value and cut-off score of our IMN criteria.

Background: Fusarium graminearum is a devastating fungal pathogen that poses a significant threat to global wheat production and quality. Control of this toxin-producing pathogen remains a major challenge. This study aimed to isolate strains with antagonistic activity against F. graminearum and at the same time to analyze the synthesis of deoxynivalenol (DON), in order to provide a new basis for the biological control of FHB., Results: Total of 69 microorganisms were isolated from the soil of a wheat-corn crop rotation field, and an antagonistic bacterial strain F12 was identified as Burkholderia pyrrocinia by molecular biology and carbon source utilization. F. graminearum control by strain F12 showed excellent biological activities under laboratory conditions (95.8%) and field testing (63.09%). Meanwhile, the DON content of field-treated wheat grains was detected the results showed that F12 have significantly inhibited of DON, which was further verified by qPCR that F12 produces secondary metabolites that inhibit the expression of DON and pigment-related genes. In addition, the sterile fermentation broth of F12 not only inhibited mycelial growth and spore germination, but also prevented mycelia from producing spores., Conclusion: In this study B. pyrrocinia was reported to have good control of FHB and inhibition of DON synthesis. This novel B. pyrrocinia F12 is a promising biological inoculant, providing possibilities for controlling FHB, and a theoretical basis for the development of potential biocontrol agents and biofertilizers for agricultural use. © 2024 Society of Chemical Industry., (© 2024 Society of Chemical Industry.)

Background: Central post-stroke pain (CPSP) significantly interferes with the quality of life and psychological well-being of stroke patients. Non-invasive brain stimulation (NIBS) has attracted significant attention as an emerging method for treating patients with CPSP., Objective: To compare the clinical efficacy of noninvasive brain stimulation on pain, and psychological status of patients with central post-stroke pain using meta-analysis., Methods: A computerized search of multiple databases was performed for identification of randomized controlled trials involving NIBS-led treatment of CPSP patients. Two researchers worked independently on literature screening, data extraction, and quality assessment. Research was conducted from inception of the database until October 2023. RevMan 5.0 and Stata 15.0 software were used to conduct statistical analysis., Results: Sixteen papers with 807 patients were finally included. The results showed that NIBS reduced patients' pain intensity [ SMD  = -0.39, 95% CI (-0.54, -0.24), p  < 0.01] and was more effective in short-term CPSP patients. However, the included studies did not show a significant impact on psychological status, particularly depression. Subgroup analysis suggested that the M1 stimulation point was more effective than other stimulation points [ SMD  = -0.45, 95% CI (-0.65, -0.25), p  < 0.001]. Other stimulation modalities also demonstrated favorable outcomes when compared to rTMS [ SMD  = -0.67, 95% CI (-1.09, -0.25), p  < 0.01]., Conclusion: NIBS has a positive impact on pain relief in patients with CPSP, but does not enhance patients' psychological well-being in terms of anxiety or depression. Furthermore, large-sample, high-quality, and multi-center RCTs are needed to explore the benefits of different stimulation durations and parameters in patients with CPSP. The current study has been registered with Prospero under the registration number CRD42023468419.

A high-precision binocular camera calibration method is proposed to address the issues of poor calibration accuracy and large calibration errors in current practical applications. This method uses a triangular stereo sphere as the calibration object and employs steps, such as ellipse fitting, Cholesky decomposition, homography matrix solution, and nonlinear optimization, to compute the intrinsic and extrinsic parameters, distortion parameters, and relative pose of the binocular camera. Moreover, this method simplifies the correspondences between primitives, enabling simultaneous calibration of multiple viewpoint cameras. This method is also suitable for both binocular cameras consisting of two different structured monocular cameras and those composed of two image sensors within the same structure. Experimental results showed that this method outperforms traditional algorithms in terms of binocular camera calibration accuracy, calibration errors between left and right cameras, and robustness, resulting in a significant improvement in overall algorithm performance.

Objective: To evaluate the effect of ginger with P6 acupressure in preventing and treating chemotherapy-induced nausea and vomiting (CINV) in cancer patients., Method: A total of 172 participants were randomly divided into the control, ginger, acupressure, and joint groups, who were hospitalized in the Affiliated Hospital of Xuzhou Medical University from February and September 2022. The baseline characteristics, nausea, vomiting, and retching, benefit finding, functional living index-emesis, treatment satisfaction, and adverse reaction, were used in data collection., Results: No significant difference was found in benefit finding and adverse reactions among the four groups (P > 0.05). Ginger significantly improved delayed CINV and function living index-nausea (P < 0.05) but had no significant effect on acute CINV, retching, and delayed vomiting, functional living index-emesis, and treatment satisfaction (P>0.05). Acute nausea and retching, delayed nausea, vomiting, and retching, functional living index-emesis, and treatment satisfaction were effectively improved in the acupressure and joint groups (P < 0.05)., Conclusion: Ginger with P6 acupressure may contribute to improving CINV in patients undergoing chemotherapy.

Objective: To investigate the correlation between changes in brain activity associated with working memory and assessment scales of memory scores in amnestic mild cognitive impairment (aMCI) before and after moxibustion therapy., Methods: aMCI patients were randomized into the moxibustion treatment (MT) group and the placebo moxibustion (PM) group. Each group received either moxibustion therapy or a placebo moxibustion for eight weeks. Neuropsychological performance and functional brain responses to a working memory task were assessed at baseline and at the end of treatment. Memory function was evaluated individually by the Rivermead behavioral memory test (RBMT), and working memory was assessed by the N-back task., Results: Compared with the PM group, RBMT score changes were significant ( < 0.05). In the MT group, the accuracy of the N-back texts increased compared with those before the intervention. After moxibustion intervention, the right insula, postcentral gyrus, precentral gyrus, superior temporal gyrus, thalamus, lingual gyrus, calcarine sulcus, posterior cingulate gyrus, middle frontal gyrus and anterior frontal gyrus were significantly activated (= 0.01, Cluster-level Family-Wise Error = 0.05). Pearson correlation analysis showed that the insula, lingual gyrus and posterior cingulate gyrus were associated with changes in N-back score. Spearman correlation analysis showed that the postcentral gyrus, superior temporal gyrus, thalamus, lingual gyrus, and posterior cingulate gyrus were correlated with RBMT score changes., Conclusion: Moxibustion treatment improved memory in aMCI patients and was associated with the activation of the brain region of the insula, lingual gyrus, posterior cingulate gyrus, postcentral gyrus, superior temporal gyrus, and thalamus, which may be an important mechanism by which moxibustion improves the memory function.

Background: The participation of providers and patients in medical communication is the core element of shared decision making. Furthermore, web-based pharmaceutical care consultation is increasingly necessary, welcomed and popular., Objective: This study aimed to analyze the participation of pharmacists and patients in web-based pharmaceutical care consultation, so as to form the promotion strategy for both parties' participation., Methods: Data of pharmacist-patient encounters was obtained from the online platform 'Good Doctor Website' from March 31, 2012 to June 22, 2019. MEDICODE was employed to analyze the participation of pharmacists and patients in web-based pharmaceutical care consultation using dialogue ratio, the preponderance of initiative, and dialogical roles (information provider, listener, instigator and participant)., Results: This study included 121 pharmacist-patient encounters which discussed 382 specifically named medications. On average, 3.75 specific themes were discussed per medication. Among the 29 specific themes observed, 16 were initiated primarily by patients and 13 by pharmacists, 22 were primarily monologue, 6 were primarily dialogue, and 1 was a combination of the two. Pharmacists and patients were information providers or listeners in most content theme categories, such as possible main effect, possible adverse effect, instructions, warnings, adherence, designation, and observed adverse effect., Conclusions: Pharmacists and patients exchanged less drug-related information in web-based pharmaceutical care consultation. The exchange had more patient-dominated behaviors and more of a monologue. Furthermore, pharmacists and patients were mainly information providers or listeners in communication. The participation of both parties was insufficient., Competing Interests: Declaration of Competing Interest The authors declare that they have no known competing financial interests or personal relationships that could have appeared to influence the work reported in this paper., (Copyright © 2023 Elsevier B.V.

Tendon calcification is a common disease, with the shoulder rotator cuff being the most common site. However, calcific tendinitis of the gluteus medius has rarely been reported. This study reports the case of a 64-year-old woman diagnosed with calcific tendinitis of the gluteus medius and experiencing right lateral hip pain with no apparent trigger. After unsuccessful conservative treatment, hip endoscopy was performed on this patient, allowing for a clear view of a "toothpaste-like" lesion in the gluteus medius tendon. A shaver was used to remove the lesion. After 8 weeks and 14 months of follow-up, the patient could return to regular daily and social activities. This study shows that endoscopic surgery can lead to effective, rapid recovery and minimally invasive clinical outcomes in patients with tendon calcification near the hip joint., 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., (© 2022 Jian, Dan and Gangliang.)

Background and Aims: Cardiac enzymes are recognized as a valuable tool for predicting the prognosis of various cardiovascular diseases. The prognostic value of alpha-hydroxybutyrate dehydrogenase (α-HBDH) in patients with intracerebral hemorrhage (ICH) was ambiguous and not evaluated., Methods: Two hundred and thirteen Chinese patients with ICH participated in the study from December 2018 to December 2019. Laboratory routine tests and cardiac enzymes, including α-HBDH level, were examined and analyzed. All the patients were classified into two groups by the median value of α-HBDH: B1 <175.90 and B2 ≥175.90 U/L. The clinical outcomes included functional outcome (according to modified Rankin Scale (mRS) score ≥3), all-cause death, and recurrent cerebro-cardiovascular events 1 year after discharge. Associations between the α-HBDH and the outcomes were evaluated using logistic regression analysis. Univariate survival analysis was performed by the Kaplan-Meier method and log-rank test., Results: Of the 213 patients, 117 had α-HBDH ≥175.90 U/L. Eighty-two patients had poor functional outcomes (mRS≥3). During the 1-year follow-up, a total of 20 patients died, and 15 of them had α-HBDH ≥175.90 U/L during the follow-up time. Moreover, 24 recurrent events were recorded. After adjusting confounding factors, α-HBDH (≥175.90) remained an indicator of poor outcome (mRS 3-6), all-cause death, and recurrent cerebro-cardiovascular events. The ORs for B2 vs. B1 were 4.78 (95% CI: 2.60 to 8.78, P = 0.001), 2.63 (95% CI: 0.80 to 8.59, P = 0.11), and 2.40 (95% CI: 0.82 to 7.02, P = 0.11) for poor functional outcomes with mRS ≥ 3, all-cause death, and recurrent cerebro-cardiovascular events, respectively., Conclusion: Increased α-HBDH at admission was independently related to poor functional outcome and all-cause mortality in patients with ICH at 1-year follow-up., 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 Limin, Alsamani, Jianwei, Yijun, Dan, Yuehong, Ziwei, Huiwen, Dongzhi, Xingquan and Guojun.)

Previous studies have shown that the soil microbial population and soil enzyme activity are seriously affected by fracturing flow-back fluid (FFBF) from the shale gas mining process. However, the toxic effect of FFBF on specific bacteria, fungi, and plankton has not been systematically confirmed in detail. In this paper, a toxic effect evaluation of FFBF was conducted using the representative toxicity test organisms Vibrio fischeri, Daphnia, Aspergillus niger, and S. cerevisiae, indicating that FFBF can significantly decrease the survival rate of these species. The results also showed that there was a significant negative correlation between the concentration of some inorganic toxicity factors and the survival rate when Daphnia was used as the test organism, indicating that the toxicity degree order for these inorganic toxicity factors is Ba 2+  > Li +  > As 3+  > Cl -  > Cu 2+  > Rb 2+  > Ga 2+  > V 2+  > Na + . In addition, other toxic factors, including polycyclic aromatic hydrocarbons (PAHs), were also determined, and the order of toxic effects with a negative correlation to the Daphnia survival rate was confirmed. These results showed that the biological toxicity of FFBF was caused not only by inorganic toxicity factors such as heavy metals but also by organic compounds such as PAHs. The results not only provide a significant reference value for the systematic assessment of biological toxicity by FFBF, but they also have great significance for developing approaches to appropriate FFBF treatment., (© 2022.

Endometriosis is a serious human gynecological disorder of women of reproductive age. The present study was designed to explore the therapeutic implications of rhein in the management of endometriosis. The results showed that rhein significantly (p<0.05) inhibited the proliferation of endometrial stroma cells in a dose-dependent fashion. Besides, the rhein treated endometrial stroma cells showed significantly (p<0.05) lower migration and invasion, in vitro. Transwell and wound healing assays showed that rhein also suppressed the migration and invasion of the endometrial stroma cells. Rhein was shown to target miR-135 at the molecular level to exert its anti-proliferative effects against the human endometrial stroma cells. Conversely, overexpression of miR-135 could nullify the anti-proliferative effects of rhein. Taken together, the findings of the present study highlight the therapeutic utility of rhein against human endometriosis. However, more in vivo studies are required.

In recent years, secondary metabolites of plants have attracted researchers' interest as a substitute for synthetic insecticides with many advantages. Elsholtzia kachinensis is an annual herb with medicinal and edible value. In this study, the essential oil (EO) of the aerial part of E. kachinensis was extracted by hydrodistillation, and GC-MS analysed essential oil components. The results show that carvone and dehydroelsholtzia ketone are the main components of the essential oil, accounting for 32.298% and 31.540%, respectively. EO, carvone and dehydroelsholtzia ketone are used to determine the effects against stored-product insects Lasioderma serricorne, Tribolium castaneum, Sitophilus oryzae and Liposcelis bostrychophila. The essential oil showed the most vital contact and fumigation toxicity to L. serricorne, of which LD 50 and LC 50 values were 3.85 μg/adult and 7.74 mg/L air, respectively. S. oryzae did not show repellent activity, but the repellent rate of the other three species reached 90% under EO treatment at a concentration of 78.63 nL/cm 2 . Therefore, the essential oil of E. kachinensis has an insecticidal effect and has the potential to be developed as a new eco-friendly insecticide.

Background and Aims: The apolipoprotein B (apoB)/apolipoprotein A1 (apoA1) ratio is a key indicator in predicting future cardiovascular outcomes. However, it is still unclear whether the ratio of apoB/apoA1 is a better predictor of the outcomes after intracerebral hemorrhage (ICH). Therefore, we aimed to assess the relationships between the ratio of apoB/apoA1 and functional outcomes, all-cause mortality, and stroke recurrence in ICH patients., Methods: Two hundred and sixteen Chinese ICH patients participated in this study from December 2018 to December 2019. Laboratory routine tests including hematology analysis, coagulation tests, and lipid levels were examined. The clinical outcomes included functional outcomes evaluated by the modified Rankin Scale score (mRS), all-cause death, and stroke recurrence 1 year after discharge. Associations between the apoB/apoA1 ratio and the outcomes were evaluated using logistic regression analysis. Based on multivariate analysis, we constructed a nomogram. Univariate survival analysis was performed by the Kaplan-Meier method and log-rank test. All the patients were classified into two groups by the median value of the apoB/apoA1 ratio: B1 < 0.8 and B2 ≥ 0.8., Results: Of the 216 patients, 107 had an apoB/apoA1 ratio ≥ 0.8. Eighty-five patients had poor functional outcomes (mRS ≥ 3), and 32 patients had severe functional outcomes (mRS ≥ 4). During the 1-year follow-up, a total of 18 patients died, and 13 patients had apoB/apoA1 ratio levels ≥0.8 during the 1-year follow-up period. Moreover, 16 recurrent strokes were recorded. Adjustments for age, sex, smoking, alcohol, body mass index, lipid levels, and hematoma site and volume showed that a high apoB/apoA1 ratio was significantly related to adverse functional outcomes and all-cause mortality. The ORs for B2 versus B1 were 3.76 (95% CI: 1.37 to 10.40, p = 0.010), 22.74 (95% CI: 1.08 to 474.65, p = 0.044), and 7.23 (95% CI: 1.28 to 40.88, p = 0.025) for poor functional outcomes with mRS ≥ 3, mRS ≥ 4, and all-cause mortality, respectively., Conclusion: An increased apoB/apoA1 ratio at admission was independently related to poor functional outcome and all-cause mortality in ICH patients at the 1-year follow-up., (© 2022 The Authors.

Competitive tennis is developing in the direction of quantification. How to use and give full play to all positive factors, in order to attack actively and give full play to the limits of body and psychology, breathing, as the basic metabolic function of human body, also plays a vital role in tennis. This paper studies that it plays an important role in the rationality and explosiveness of sports and the psychological and physiological regulation in competition. The characteristics of tennis events determine the importance of scientific and rational breathing. Reasonable breathing during exercise is conducive to maintaining the basic stability of the internal environment, improving the training effect, and giving full play to the functional ability of the human body, so as to create excellent sports results. First, reduce respiratory resistance. Second, there are two methods to improve alveolar ventilation efficiency and pulmonary ventilation: increasing respiratory rate and increasing respiratory depth. When the inhalation volume is constant, the alveolar gas freshness rate depends on the functional residual volume in the alveolar cavity at the end of expiratory or before inhalation. The less functional the residual air, the more fresh air inhaled, and the higher the oxygen partial pressure in alveolar gas. An effective way to reduce the functional residual volume in the alveolar cavity is to exhale as deeply as possible, so as to ensure that more oxygen enters the body. Reasonable breathing methods can not only accelerate the excitation of the body, increase movement strength, reduce fatigue, and promote recovery but also play a vital role in the rational allocation of physical fitness and the improvement of sports performance. The purpose of this study is to provide a theoretical basis for scientific tennis training by analyzing the characteristics of tennis events, the form of breathing in tennis and the efficiency of reasonable breathing in tennis., Competing Interests: The authors declare that they have no conflicts of interest., (Copyright © 2022 Honghua Ren and Wang Dan.)

Gestational diabetes mellitus (GDM) has become a worldwide problem in recent years. Macrosomia, a primary consequence of GDM, has short-term and life-long consequences in the offspring of mothers with GDM. Our previous study showed that miR-517a was dysregulated in placenta and plasma of fetal growth restriction through inhibiting invasion of trophoblast and might be closely related with the regulation of birth weight by the placenta. To further investigate the mechanism of miR-517a, we conducted genome-wide microarray profile of lncRNAs. lncRNA-SNX17 was found to be significantly upregulated in the placenta of diabetic macrosomia by qRT-PCR, and the expression of miR-517a and IGF-1 were measured by qRT-PCR and Western blot. Interestingly, significant inverse correlations of the miR-517a with both lncRNA-SNX17 and IGF-1 expression were revealed in the placenta of diabetic macrosomia. Bioinformatic prediction also revealed that both lncRNA-SNX17 and IGF-1 possessed binding sites for miR-517a, which were then confirmed by luciferase report assay. LncRNA-SNX17 overexpression reduced the expression of miR-517a and increased the IGF-1 expression in HTR-8/SVneo human trophoblast cell line and thus enhanced the proliferation of HTR-8/SVneo. The enhancement of HTR-8/SVneo proliferation by lncRNA-SXN17 could be nullified by co-transfection of miR-517a mimics. The data suggested that lncRNA-SNX17 might promote the trophoblast proliferation through miR-517a/IGF-1 pathway and might play a role in the placentation of diabetic macrosomia., (© 2021.

Red ginseng is a traditional Chinese herbal medicine that has long been used to treat diabetes, and its blood sugar-lowering activity has been confirmed. However, the mechanism of action of red ginseng on type 2 diabetes mellitus (T2DM) at the metabolic level is still unclear. The purpose of this study is to investigate the effect of red ginseng extract in the treatment of T2DM rats based on untargeted metabolomics. The rat model of T2DM was induced by a high-fat diet (HFD) combined with streptozotocin (STZ), and serum samples were collected after four weeks of treatment. The ultra-high-performance liquid chromatography coupled with Q Exactive HF-X Mass Spectrometer was used to analyze the level of metabolites in serum to evaluate the differences in metabolic levels between different groups. The results of biochemical analysis showed that red ginseng extract intervention significantly improved the levels of total cholesterol (TC), high-density lipoprotein cholesterol (HDL-C), serum glucose (GLU), and fasting insulin (FINS) after four weeks. Orthogonal partial least squares discriminant analysis was used to study the overall changes of rat metabolomics. After the intervention of red ginseng extract, 50 biomarkers showed a callback trend. Metabolic pathway enrichment analysis showed that the regulated pathways were D-arginine and D-ornithine metabolism, D-glutamine and D-glutamate metabolism, taurine and hypotaurine metabolism, arginine biosynthesis, and tryptophan metabolism. Generally, the results demonstrated that red ginseng extract had beneficial effects on T2DM, which could be mediated via ameliorating the metabolic disorders., (Copyright © 2021 The Authors.

Objectives: To evaluate the sedative and analgesic effects of dexmedetomidine combined with propofol intravenous anesthesia in laparoscopic day surgery in pediatric urology., Methods: Eighty male children with cryptorchidism and hydrocele who underwent laparoscopic daytime surgery in our hospital from January 2019 to January 2021 were selected and randomly divided into two groups: the experimental group and the control group. Children in the experimental group ranged in age from 5.7 to 11.3, with an average of 8.52±2.17 years old, while those in the control group ranged in age from 5.3 to 12.0, with an average of 8.60±2.07 years old. There were 12 cases of cryptorchidism and 28 cases of hydrocele in the experimental group, and 14 cases of cryptorchidism and 26 cases of hydrocele in the control group. Children in the control group received conventional propofol intravenous combined anesthesia, while those in the experimental group were given dexmedetomidine (2-5 ug/kg) intranasally on the basis of conventional propofol intravenous anesthesia. The anesthetic effect, analgesic effect, serum levels of inflammatory cytokines before and after surgery and adverse drug reactions in the two groups were compared and analyzed., Results: The awakening time, extubation time and retention time in the resuscitation room of the experimental group were shorter than those of the control group, with a statistically significant difference (P<0.05); The VAS pain scores of the experimental group were significantly lower than those of the control group at 15minutes, 12hour and 24hour after awakening, with a statistically significant difference (P<0.05). In addition, the levels of TNF-a, CRP, IL-6 and other inflammatory factors in the control group were significantly higher compared with those in the experimental group 24h after surgery, with a statistical significance (TNF-a, P=0.02; CRP, P=0.00; IL-6, P=0.03); The incidence of adverse drug reactions in the experimental group was 17.5%, while that in the control group was 12.5%, which was not statistically significant (P=0.53)., Conclusion: Dexmedetomidine combined with intravenous propofol anesthesia may be helpful to shorten the extubation time, the recovery time and the stay time in the anesthesia resuscative room, improve the analgesic effect, and may reduce the inflammatory response and the expression of serum inflammatory cytokines, with no significant increase in side effects., Competing Interests: Conflicts of interest: None., (Copyright: © Pakistan Journal of Medical Sciences.)

Objective: To evaluate the clinical effect of high-dose intravenous immunoglobulin (HDIVIG) single dose and pulse therapy combined with small-dose prednisone acetate in the treatment of patients with Kawasaki disease (KD)., Methods: Eighty patients with KD from Baoding Children's Hospital, China, were randomly divided into two groups: the experimental group and the control group, each with 40 cases. Patients in the experimental group were treated with HDIVIG single dose, pulse therapy combined with low-dose prednisone acetate, while patients in the control group were treated with conventional-dose immunoglobulin. Patients in both groups were treated with aspirin orally, and given symptomatic treatment including anti-inflammatory, nutritional support, correction of water and electrolyte disturbance and acid-base balance. Peripheral venous blood samples were drawn from all patients at the time of admission, Day-1, Day-7 and Day-14 after treatment, and in the basic state of getting up in the morning, and then the levels of tumor necrosis factor (TNF-a), C-reactive protein (CRP), interleukin-6 (IL-6) and other inflammatory factors were detected by enzyme-linked immunosorbent assay (ELISA). The time of body temperature falling to normal, lymph node swelling recovery, hands and feet swelling, mucosal hyperemia regression after treatment in the two groups was recorded, and the treatment effect of the two groups was comprehensively evaluated., Results: After treatment, the levels of inflammatory factors such as TNF-a, CRP, IL-6 in the experimental group were significantly lower than those in the control group, with a statistically significant difference (P<0.05). In addition, the time of body temperature falling to normal, lymph node swelling recovery, hands and feet swelling, and mucosal hyperemia regression in the experimental group was significantly shorter than that in the control group (p=0.00). The effective rate of the experimental group was 95% and that of the control group was 80%, with a statistically significant difference (p=0.04)., Conclusion: HDIVIG single dose, pulse therapy combined with small-dose prednisone acetate has a favourable therapeutic effect in the treatment of patients with KD, by which the inflammatory factors can be significantly improved, clinical symptoms and weight can be quickly ameliorated, and therapeutic effect can be enhanced., Competing Interests: Conflicts of interest: None., (Copyright: © Pakistan Journal of Medical Sciences.)

Objective: To assess the correlation between Z-scores of positive noninvasive prenatal testing (NIPT) results and the positive predictive value (PPV) of NIPT., Methods: Pregnancies with positive NIPT results at Guangzhou Women and Children's Medical Centre between July 2017 and May 2020 were included in this study. Fetal karyotyping or microarray analysis was provided to patients with abnormal NIPT results for confirmatory testing. Logistic regression analyses was applied to study the relationship between the Z scores and the PPV performance. The optimal cutoff values for indicating fetal common trisomies were obtained based on receiver operating characteristic (ROC) curve analysis, and then the PPV were calculated in pregnancies with positive NIPT results at Z-score greater than or equal to cutoff value and in patients with a Z-score between 3 and cutoff value respectively., Results: A total of 214 pregnancies with positive NIPT results for fetal common trisomies were validated by invasive prenatal diagnosis and follow up in this study. Of these, NIPT indicated trisomy 13 in 25 cases, trisomy 18 in 54 cases and trisomy 21 in 135 patients. Logistic regression analyses showed a significant association (p < 0.05) between the Z-scores and true positive results for T21 and T18. For T13, the significant association was not observed (p > 0.05). The ROC curve analysis showed that the optimal cutoff Z-score for indicating fetal trisomies 13, 18, and 21 were 6.889, 7.574 and 6.612 respectively, and the corresponding area under curve were 0.706, 0.916, and 0.954. In this cohort with abnormal NIPT results, the cutoff values revealed a sensitivity of 96.8% and a specificity of 90% for indicating trisomies 21, and a sensitivity of 88.9% and a specificity of 92.6% for trisomies 18. However, probably due to the sample size, the sensitivity and specificity for indicating trisomy 13 were lower (85.7% and 61.1%) than that for trisomies 21 and 18. The PPVs in pregnancies with positive NIPT results at Z-score greater than or equal to cutoff value were 99.18% (121/122) for trisomy 21, 92.31% (24/26) for trisomy 18 and 46.15% (6/13) for trisomy 13. In patients with a Z-score between 3 and cutoff Z-score, the PPV of NIPT for trisomies 21, 18, and 13 were 30.77% (4/13), 10.71% (3/28), and 8.33% (1/12) respectively. Moreover, by classifying Z scores as 3 ≤ Z < 5, 5 ≤ Z < 10, and Z ≥ 10, the majority of Z scores were above 10 with a PPV of 99% for T21 and just 5.2% were between 3 and 5 with a PPV of 14.3%. In contrast for T18, over a third of tests had Z scores between 3 and 5. The PPV in this group is just over 5%., Conclusions: The present results show that the PPV performance of NIPT for fetal trisomies 13, 18, and 21 are closely associated with Z-score. The higher the Z-score, the greater the likelihood that the aneuploidy result is correct. Our experience in evaluating the Z-score accuracy of NIPT in this study could be of use in similar work., (© 2021 John Wiley & Sons Ltd.)

Objectives: The objective of the study was to establish the quality standard of the formulation of Shenkui Tongmai granules (SKTM) from the perspective of safety and effectiveness., Methods: A sensitive and specific method to simultaneously detect seven effective components by ultra-high performance liquid chromatography-tandem-mass spectrometry (UHPLC-MS/MS) in SKTM, including calycosin 7-O-β-d-glucopyranoside, icariin, sodium danshensu, hyperoside, astragaloside IV, hesperidin, and salvianolic acid, was developed and validated. A Kromasil 100-3.5 C18 column with a mobile phase of 6.5 mmol/l ammonium acetate in acetonitrile was used to separate these above-listed components. Gradient programming was used with a flow rate of 0.2 ml/min, and the components were achieved in 13 min. Multiple reaction monitoring (MRM) in positive/negative mode was applied for the MS/MS detection., Key Findings: The analytical method was satisfactorily validated for linearity, accuracy and precision, repeatability and stability. The developed UHPLC-MS/MS method had high repeatability and accuracy and it was in a good linear relationship within their respective ranges (r = 0.9999) with the RSD value of the sample recovery of less than 5%., Conclusions: The current method established here is suitable for use in determining seven effective components in SKTM simultaneously, which may provide a new reliable method for overall quality control of SKTM., (© The Author(s) 2021.

Schistosomiasis is a major public health problem that is included in the neglected tropical diseases. The early diagnosis and detection of the pathogen are of critical importance in the control of the disease. The diagnostic techniques in use include the detection of worm's eggs in fecal examination or detection of circulating antigens in immunological based assays. These traditional strategies lack sensitivity in earlier detection of the schistosomiasis. Cell-free DNA (cfDNA) that includes the fragments of parasitic DNA circulating in the body fluids of host offers an alternative mean for the rapid pathogen detection and thus is a useful diagnostic tool. In this study, we explored the usefulness of the mitochondrial cfDNA markers for the diagnosis of schistosomiasis from the experimentally infected hosts (rabbits and mice). In this study we found mitochondrial DNA fragment cytochrome B gene as persistent and useful cfDNA marker for the early detection of schistosomiasis. We evaluated the sensitivity of cfDNA marker with varying numbers of cercaria. Overall, our results suggest that cfDNA markers can be useful for developing a diagnostic tool for the detection of S. japonicum infection., (Copyright © 2020. Published by Elsevier B.V.)

In this study, the chemical profiling of Jingyin Granules and the tissue distribution of nine major constituents in this Chinese medicine were performed after oral administration of Jingyin Granules to rats, by using UHPLC-Q-Exactive Orbitrap HR-MS. An Acquity UPLC BEH C&#95;(18) chromatographic column(2.1 mm×100 mm, 1.7 μm) was used as solid phase, while the mobile phase was methanol and 0.1% formic acid water for gradient elution. The major constituents in this Chinese medicine were quickly and accurately identified, via comparison with the retention times and MS/MS spectra of the standards. A total of 106 chemicals were identified from Jingyin Granules, including 24 kinds of organic acids, 47 kinds of flavonoids, 10 kinds of iridoids, and 21 kinds of saponins and 4 kinds of other compounds. After oral administered Jingyin Granules to rats, 48, 30, 25, 23, 45, 34, 39, 26, 19 prototype compounds were identified in serum, heart, liver, spleen, lung, kidney, brain, fat, and testicles, respectively. Meanwhile, an LC-MS based analytical method was established for simultaneous determination of chlorogenic acid, swertiamarin, caffeic acid, sweroside, liquiritin, prim-O-glucosylcimifugin, arctiin, 5-O-methylvisammioside and arctigenin in biological samples. The tissue distribution(serum, liver and lung) of these nine aim constituents in rats after oral administration of Jingyin Granules were investigated. It was found that these nine constituents could be quickly absorbed into circulation system and then distributed to liver and lung tissues. Except arctigenin, the exposure of other eight aim constituents to serum and lung was peaked at 1 h. At 1 h, the exposure of these components to lung tissue were ranked as follows: swertiamarin [(75 191.0±3 483.21) ng·g~(-1)]&gt;arctiin [(2 716.5±36.06) ng·g~(-1)]&gt;5-O-methylvisammioside [(585.1±0.71) ng·g~(-1)]&gt;arctigenin [(437.45±3.18) ng·g~(-1)]&gt;chlorogenic acid [(308.1±5.66) ng·g~(-1)]&gt;prim-O-glucosylcimifugin [(211.35±2.19) ng·g~(-1)]&gt;sweroside [(184.3±9.05) ng·g~(-1)]&gt;caffeic acid [(175.95±2.05) ng·g~(-1)]&gt;liquiritin [(174.78±153.34) ng·g~(-1)]. In summary, an UHPLC-Q-Exactive Orbitrap HR-MS method has been established for rapid and accurate identification of the constituents in Jingyin Granules, while the tissue distribution of nine major absorpted constituents were investigated in rats following oral administration of Jingyin Granules. These findings provided key information and guidance for further studies on pharmacodynamic substances and clinical applications of Jingyin Granules.

This work was carried out to establish and validate the specific characteristic chromatography of Scutellaria Extract and evaluate the quality of commercial Scutellaria Extract and optimize production process parameters. Scutellaria Extract and formulation samples collected from different manufacturers were analyzed using HPLC-characteristic chromatogram. The HPLC characteristic peaks were considered to be the index for the parameters optimization in preparations of Scutellaria Extract. The chemical pattern recognization was applied for the analysis of characteristic peak data. The established characteristic fingerprint method possessed a good precision, repeatability, and stability. Ten common characteristic peaks were determined and identified in the specific chromatogram of 31 batches of Scutellaria Extract and 4 batches of formulation. The process parameters influenced the characteristic peaks area significantly. The similarity analysis results showed that after removing baicalin peak, the similarity of the characteristic chromatography of 9 samples were less than 0.90, indicating that the quality of commercial Scutellaria Extract was inconsistent. Non-parametric test result showed that the relative peaks area of the number 4, 6, 7 characteristic peaks had significant differences(P&lt;0.05), indicating the differences of the Scutellaria Extract quality were mainly reflected in the characteristic peaks 4, 6 and 7(norwogonin-7-O-glucuronide, oroxylin A-7-O-glucuronide, wogonoside, respectively). The cluster analysis accurately classified 31 extract samples and 4 formulation samples into five categories based on 10 characteristic peaks. The quality of Scutellaria Extracts was comprehensively evaluated and ranked by PCA. The result showed that the higher content of baicalin, the score value of quality(F value) was lower, and the quality of the Scutellaria Extract should be evaluated by multi-components instead of a single baicalin component. The optimized characteristic peaks method is stable and reliable. It is advantageous for the extract and formulations integrative quality control by combining the chemical pattern recognization.

Purpose: To investigate the findings of plain spectral computed tomography (CT) with multiparameter of early cerebral ischemia., Patients and Methods: Thirty-three patients with suspected early cerebral ischemia who received a one-stop CT examination (plain scan with spectral CT imaging mode, CTP and CTA) of the brain were enrolled in this study. No clear lesion was observed in any patient on the plain CT. However, the CTA displayed evidence of vascular stenosis and the CTP displayed a corresponding low perfusion area consistent with early cerebral ischemia. Regions of interest were placed in the abnormal perfusion regions and the contralateral symmetric regions on plain CT. Then, the CT value of the monochromatic images (70 kV), the slope of the spectral HU curve, blood (iodine), iodine (water), and water (iodine) concentrations were measured. A paired t-test was performed for data comparison. The receiver operating characteristic curve was used to evaluate diagnostic performance., Results: The CT values of the ischemic regions at 70 keV, the spectral HU curve, water, and blood values of the ischemic measurements were slightly lower than those of the contralateral symmetric regions (P < .05). Monochromatic images at 70 keV had the highest area under the curve value, and the sensitivity and specificity were 90.0% and 63.0%, respectively., Conclusion: The difference of monochromatic CT values, spectral HU curve, and basic material concentrations between the early cerebral ischemia region and the contralateral symmetric region on spectral CT imaging may provide a reference with the diagnosis of early cerebral ischemia.

Objective: To investigate the prevalence of medical adhesive-related skin injuries (MARSIs) and associated risk factors in a pediatric ICU (PICU)., Methods: A cross-sectional design was adopted in the PICU of a university-based children's hospital in eastern China. A total of 232 patients were enrolled, and 611 person-days were analyzed., Main Outcome Measures: Researchers assessed all patients daily for 2 weeks. The use of adhesives and prevalence of MARSIs were recorded. The patients' clinical data were also collected. The prevalence of MARSIs was calculated daily, and the risk factors were examined statistically., Main Results: The MARSI prevalence ranged from 23.53% to 54.17% (mean, 37.15%). Multivariate analysis identified being female, age 2 years or younger, hospital stays longer than 5 days, infection, edema, and surgery as independent risk factors. Prevalence by product ranged from 19 to 53 per 1,000 product-days with a mean of 34 MARSIs per 1,000 product-days. The major MARSI types were epidermal stripping and skin tear. The face was the most common MARSI site, and tracheal intubation was the most common inciting condition. Implicated products were acrylate tapes with elastic cloth backings., Conclusions: Researchers concluded that MARSI is common in the PICU. Skin stripping and skin tear were the most common types, and the face was the most vulnerable site for MARSI, typically attributable to the cloth tape used to affix tracheal intubation. Careful attention should be paid to children with identified risk factors (females, age 2 years or younger, longer hospital stays, edema, infection, or surgery).

Aldosterone, with pro-oxidation and pro-autophagy capabilities, plays a key role in liver fibrosis. However, the mechanisms underlying aldosterone-promoted liver sinusoidal endothelial cells (LSECs) defenestration remain unknown. Caveolin 1 (Cav1) displays close links with autophagy and fenestration. Hence, we aim to investigate the role of Cav1-related autophagy in LSECs defenestration. We found the increase of aldosterone/MR (mineralocorticoid receptor) level, oxidation, autophagy, and defenestration in LSECs in the human fibrotic liver, BDL or hyperaldosteronism models; while antagonizing aldosterone or inhibiting autophagy relieved LSECs defenestration in BDL-induced fibrosis or hyperaldosteronism models. In vitro, fenestrae of primary LSECs gradually shrank, along with the down-regulation of the NO-dependent pathway and the augment of the AMPK-dependent autophagy; these effects were aggravated by rapamycin (an autophagy activator) or aldosterone treatment. Additionally, aldosterone increased oxidation mediated by Cav1, reduced ATP generation, and subsequently induced the AMPK-dependent autophagy, leading to the down-regulation of the NO-dependent pathway and LSECs defenestration. These effects were reversed by MR antagonist spironolactone, antioxidants or autophagy inhibitors. Besides, aldosterone enhanced the co-immunoprecipitation of Cav1 with p62 and ubiquitin, and induced Cav1 co-immunofluorescence staining with LC3, ubiquitin, and F-actin in the perinuclear area of LSECs. Furthermore, aldosterone treatment increased the membrane protein level of Cav1, whereas decrease the cytoplasmic protein level of Cav1, indicating that aldosterone induced Cav1-related selective autophagy and F-actin remodeling to promote defenestration. Consequently, Cav1-related selective autophagy initiated by aldosterone-induced oxidation promotes LSECs defenestration via activating the AMPK-ULK1 pathway and inhibiting the NO-dependent pathway., (Copyright © 2017 The Authors.

The contrast-enhanced ultrasound (CEUS) has been a widely accepted imaging modality for diagnosis of liver cancers. In clinical practice, several typical images selected from enhancement patterns of the arterial, portal venous and late phases can provide reliable information basis for diagnosis. In this work, we propose to develop a CEUS-based computer-aided diagnosis (CAD) for liver cancers with only three typical CEUS images selected from three phases, which simulates the clinical diagnosis mode of radiologists. In the proposed CAD, the deep canonical correlation analysis (DCCA) is first performed on three CEUS pairs between arterial and portal venous phases, arterial and late phases, respectively, due to the effectiveness of multi-view fusion of DCCA. The generated six-view features are then fed to a multiple kernel learning (MKL) classifier to further promote the predictive diagnosis result. The experimental results indicate that the proposed DCCA-MKL algorithm achieves best performance for discriminating benign liver tumors from malignant liver cancers.

Computer-aided diagnosis (CAD) of liver cancers on contrast-enhanced ultrasound (CEUS) has attracted considerable attention in recent years. The enhancement patterns on CEUS for liver lesions consist of the arterial, portal venous and late phases. Several typical images selected from these three phases can provide reliable information basis for diagnosis of liver lesions. Therefore, we propose to develop a CAD framework for liver cancers with only one B-mode image and three typical CEUS images selected from three enhancement patterns, which simulates the clinical diagnosis mode of radiologists. Moreover, a framework of two-stage multi-view learning (TS-MVL) is proposed to perform both feature-level and classifier-level MVL for the diagnosis of liver cancers with multimodal ultrasound images. We propose to apply the nonlinear kernel matrix (NKM) algorithm to effectively fuse the features of multimodal ultrasound images, and then perform the multiple kernel boosting (MKB) algorithm to promote the predictive performance of multiple classifiers according to multi-view features. The experimental results indicate that the proposed algorithm outperforms the commonly used multi-view learning algorithms.

Objective: To investigate the prevalence of parasitic infections in Lhasa, Tibet., Methods: The residents in Chengguan District, Dangxiong County, Dazi County and Qushui County were selected to participate in the study in 2014, using the stratified random sampling method. Infections with the soil-borne nematodes in feces were examined in triplicates using the Kato-Katz method. Further, the Enterobius vermicularis were examined using the cellophane anal swab method in children aged 3-12 years, and the intestinal protozoa were detected by iodine staining. The parasitic infection was analyzed by sex, age, and occupation. Comparisons were made using Chi-square test., Results: A total of 1 015 residents（39.3±18.2 years: age range, 1-89 years） participated in the study, including 391 males（38.6%） and 623 females（61.4%）. Two hundred and forty-nine participants were positive for parasitic infections, with an overall infection rate of 24.5%（249/1 015）. The infection rate was 21.7%（220/1 015） for Taenia sp., 0.2%（2/1 015） for Trichuris trichiura and E. vermicularis respectively, 4.1%（42/1 015） for Entamoeba coli, 0.4%（4/1 015） for Giardia lamblia, 0.2%（2/1 015） for Iodamoeba butschlii. No infection was found for other parasites. There was no significant sexual difference in the infection rate of Taenia (male 21.2%, 83/391; female 22.0%, 137/624), T. trichiura (male 0; female 0.3%, 2/624), E. vermicularis (male 0.3%, 2/391; female 0.2%, 1/624), E. coli (male 5.4%, 21/391; female 3.4%, 21/624), G. lamblia (male 0.8%, 3/391; female 0.2%, 1/624), or I. butschlii (male 0; female 0.3%, 2/624) (P>0.05). The Taenia sp. infection rate in the age groups of 0-17, 18-29, 30-39, 40-49, 50-59 and ≥ 60 years was 10.9%（18/165）, 14.0%（18/129）, 23.0%（43/187）, 25.3%（61/241）, 26.5%（41/155）, and 28.3%（39/138）, respectively, with significant differences between groups of 0-17 and 40-49 years and between groups of 50-59 and ≥ 60 years (P<0.01). The infection rate of E. coli, T. trichiura and I. butschlii was highest in the age group of 50-59 years（6.5%, 10/155; 0.7%, 1/155; 1.3%, 2/155 respectively）. Among various occupations, farmers showed the highest infection rate for Taenia（44.5%, 147/330）, E. coli（6.4%, 21/33）, E. vermicularis （0.6%, 2/330） and I. butschlii（0.3%, 1/330）; housewives had the highest infection rate for T. trichiura（2.5%, 1/40）; and the students had the highest infection rate for G. lamblia (0.7%, 1/134)., Conclusion: There are infections with various intestinal parasites in the participants of Lhasa City, among which taenia infection reaches 20.7% while others have a low level of infection.

A novel strain, DCY107(T), was isolated from soil collected from a ginseng field in Gochang, Republic of Korea. Strain DCY107(T) is Gram-negative, yellow pigmented, non-motile, non-flagellate, rod-shaped and aerobic. The strain was found to grow optimally at 25-30 °C and pH 6.5-7. Phylogenetically, strain DCY107(T) is closely related to Chryseobacterium polytrichastri DSM 26899(T) (98.49 % 16S rRNA gene sequence similarity), Chryseobacterium yeoncheonense JCM 18516(T) (97.78 %), Chryseobacterium aahli LMG 27338(T) (97.74 %), Chryseobacterium limigenitum LMG28734(T) (97.74 %), Chryseobacterium ginsenosidimutans JCM 16719(T) (97.47 %) and Chryseobacterium gregarium LMG 24052(T) (97.31 %). The DNA-DNA relatedness values between strain DCY107(T) and reference strains were found to be clearly below 70 %. The DNA G+C content of strain DCY107(T) was determined to be 34.2 mol%. The predominant quinone was identified menaquinone 6 (MK-6). The major polar lipids were identified as phosphatidylethanolamine and unidentified lipids: aminolipids AL1, AL2 and lipid L2. C16:00, iso-C15:00, iso-C15:02OH, iso-C17:03OH and summed feature 9 (iso-C17:1 ω9c and/or C16:0 10-methyl) were identified as the major fatty acids present in strain DCY107(T). The results of physiological and biochemical tests allowed strain DCY107(T) to be differentiated phenotypically from other recognised species belonging to the genus Chryseobacterium. Therefore, it is suggested that the newly isolated organism represents a novel species, for which the name Chryseobacterium panacis sp. nov. is proposed, with the type strain designated as DCY107(T) (=CCTCC AB 2015195(T) = KCTC 42750(T)).

The AP2/ERF play a key role in multiple stress responses in plants. we here report a novel salt stress-related gene, LcAP2/ERF107 that encodes an AP2/ERF protein in Lotus corniculatus cultivar Leo. LcAP2/ERF107 was classified into the soloist subfamiliy based on phylogenetic relationship. The transcription of LcAP2/ERF107 were strongly induced by salt and other phytohormones (ABA, ACC, MeJA). A subcellular localization experiment indicated that LcAP2/ERF107 is a nuclear protein that activates transcription. LcAP2/ERF107 overexpression in Arabidopsis resulted in pleiotropic phenotypes, including higher seed germination rate and transgenic plants with enhanced tolerance to salt stress. Further, under salt tolerance the transgenic lines elevated the relative moisture content; however, the relative electrolyte leakage was lower than in control plants. The expression levels of indicative genes RD22, RD29A, LEA4-5, P5CS1 and P5CS2 were found to be increased in the transgenic plants compared with the WT plants. These results indicated that LcAP2/ERF107 play an important role in the responses of plant to salt stress.

Background: Poor ovarian response phenomenon has been observed in some of the in vitro fertilization-embryo transfer patients. Some investigations found that follicle stimulating hormone receptor ( FSHR ) gene plays a role in the process, but no direct evidence shows the correlation between genotypes of FSHR and ovarian response., Objective: Exploring the molecular mechanism behind the mutation of FSH R promoter association with ovarian granulosa cells and poor ovarian response., Materials and Methods: This cross sectional study was performed using 158 women undergoing the controlled short program ovarian stimulation for IVF treatment. The 263 bp DNA fragments before the follicle stimulating hormone (FSH) receptor 5' initiation site were sequenced in the patients under IVF cycle, 70 of which had poor ovarian response and 88 showed normal ovarian responses., Results: With a mutation rate of 40%, 63 in 158 cases showed a 29(th) site G→A point mutation; among the mutated cases, the mutation rate of the poor ovarian responders was significantly higher than the normal group (60% versus 23.9%; χ2=21.450, p<0.001). Besides, the variability was also obvious in antral follicle count, and ovum pick-ups. The estradiol peak values and the number of mature eggs between the two groups had significant difference. However, there was no obvious variability (t=0.457, p=0.324) in the basic FSH values between the two groups (normal group, 7.2±2.3 U/L; mutation group, 7.1±2.0 U/L)., Conclusion: The activity of FSHR promoter is significantly affected by the 29(th) site G→A mutation that will weaken promoter activity and result in poor response to FSH.

Cervical cancer is the third most common cancer and the fourth leading cause of cancer deaths among women in the world. The discovery of vital diagnostic and therapeutic markers against cervical squamous cell carcinoma (CSCC) would broaden our understanding on the molecular basis of CSCC. In this study, we thoroughly analyzed the transcriptome of CSCC and matched adjacent nontumor (ATN) tissue. RNA sequencing was performed to screen the differentially expressed genes (DEGs) of three pairs of CSCC and ATN tissues. Functional enrichment analysis was used to uncover the biological functions of DEGs. Protein interaction network was carried out to reveal interaction of DEGs. Quantitative real-time PCR was conducted to validate the expression of DEGs. Immunohistochemistry was used to detect the relationship between clinicopathological parameters of CSCC and DEGs. There were a total of 347 significantly common DEGs in the three paired examples, including 104 consistent upregulated and 148 consistent downregulated DEGs. The 347 DEGs were categorized into 73 functional categories by Gene Ontology (GO) analysis. The Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analysis suggested six significantly signal pathways. The protein interaction network uncovered three important DEGs, including retinol dehydrogenase 12 (RDH12), ubiquitin D (UBD), and serum amyloid A1 (SAA1). We found that RDH12 expression was decreased in 74.5 % of CSCC tissues. RDH12 expression was negatively associated with tumor size and depth of cervical invasion. The UBD was overexpressed in 61.7 % of CSCC tissues and was positively related with tumor size and lymphatic metastasis. The SAA1 protein was overexpressed in 57.4 % of CSCC tissues and was positively related with clinicopathological parameters of tumor size, lymphatic metastasis, and depth of cervical invasion. The RDH12, UBD, and SAA1 genes might participate in the progression of CSCC.

Insertion/deletion polymorphisms have become a research hot spot in forensic science due to their tremendous potential in recent years. In the present study, we investigated 30 indel loci in a Chinese Yi ethnic group. The allele frequencies of the short allele of the 30 indel loci were in the range of 0.1025-0.9221. The power of discrimination values were observed ranging from to 0.2630 (HLD111 locus) to 0.6607 (HLD70 locus) and probability of exclusion values ranged from 0.0189 (HLD111 locus) to 0.2343 (HLD56 locus). The combined power of discrimination and power of exclusion for 30 loci in the studied Yi group were 0.99999999995713 and 0.97746, respectively, which showed tremendous potential for forensic personal identification in the Yi group. Moreover, the DA distances, phylogenetic tree, principal component analysis, and cluster analysis showed the Yi group had close genetic relationships with the Tibetan, South Korean, Chinese Han, and She groups., (© 2015 WILEY-VCH Verlag GmbH & Co.

Mucosa-associated lymphoid tissue (MALT) lymphoma is an extranodal low-grade B-cell lymphoma. Pulmonary MALT lymphoma is considered to originate from bronchial MALT and is also referred to as bronchial-associated lymphoid tissue lymphoma. Pulmonary MALT lymphoma is a rare disease, but it is the most frequent subset of primary pulmonary lymphoma. The median age at diagnosis of pulmonary MALT lymphoma is 50-60 years, with only few patients aged <30 years. This is the case report of a 19-year-old patient with pulmonary MALT lymphoma presenting with a multiple pulmonary consolidation pattern on computed tomography scans, who underwent successful chemotherapeutic treatment with a chlorambucil-based regimen.

Primary giant-cell tumors rarely arise in the common bile duct. We herein report a case of primary giant-cell tumor of the common bile duct. The patient was an 81-year-old male who was diagnosed with a well-defined 1.2-cm mass projecting into the lumen of the middle common bile duct. Excision of the gallbladder and extrahepatic bile duct and a Roux-en-Y cholangiojejunostomy were performed. Histologically, the tumor had no association with carcinomas of epithelial origin and was similar to giant-cell tumors of the bone. The tumor consisted of a mixture of mononuclear and multinucleated osteoclast-like giant cells. The mononuclear cells showed no atypical features, and their nuclei were similar to those of the multinucleated giant cells. CD68 was expressed on the mononuclear and multinucleated osteoclast-like giant cells, whereas CD163 immunoreactivity was restricted to the mononuclear cells. Six months after the operation, the patient was still alive and had no recurrence. The interest of this case lies in the rarity of this entity, the difficulty of preoperative diagnosis, and this tumor's possible confusion with other malignant tumors.

Sn-glycerol-3-phosphate acyltransferase (GPAT) catalyzes the acylation at sn-1 position of glycerol-3-phosphate to produce lysophosphatidic acid (LPA) in an acyl-CoA or acyl-ACP-dependent manner, which is the initial and rate-determining step of TAG biosynthetic pathway. Some GPATs have sn-2 transfer activity. Part members of the GPAT gene family have been cloned from different plant species. Based on their subcellular localizations, GPATs can be classified into three types, plastid GPATs, mitochondria GPATs and endoplasmic reticulum GPATs. GPATs exhibit diverse biochemical properties and are involved in synthesis of several lipids such as TAG, suberin, and cutin which play important roles in the growth and development of plants. This review summarized the current understanding of the chromosomal locus and gene structure of GPAT genes and the subcellular localization, sn-2 regiospecificity, substrates specialty, and functions of GPATs in plants.

Oligodendrocyte precursor cells (OPCs) originate from restricted regions of the brain and migrate into the developing white matter, where they differentiate into oligodendrocytes and myelinate axons in the central nervous system (CNS). The molecular mechanisms that orchestrate these long distance trips of OPCs to populate throughout the CNS are poorly understood. Emerging evidence has argued the expression of N-methyl-d-aspartic acid (NMDA) receptors (NMDARs) in oligodendrocyte lineage cells in vivo, but their physiological function remains elusive. We have previously demonstrated the expression and function of NMDARs in OPC differentiation and myelination/remyelination. Here, we show that NMDARs stimulation promotes OPC migration both by chemotaxis and chemokinesis as demonstrated by various cell migration systems including Boyden transwell, single cell, matrix-gel cell mass, and SVZ tissue explants assays. The pro-migration effect of NMDAR can be abolished by either pharmacological inhibition or shRNA knock down of the T lymphoma invasion and metastasis 1 (Tiam1), a Rac1 guanine nucleotide exchange factor (Rac1-GEF) which is coexpressed and interacts with NMDAR in OPCs. Moreover, NMDAR stimulation evokes cascade activation of the Tiam1/Rac1/ERK signaling pathway which mediates its effect on OPC migration. We also show that glutamate released from cultured cortical neuron promotes OPCs migration via NMDAR, and that antagonism of NMDAR or inhibition of Tiam1 blocks the endogenous glutamate-induced OPCs migration from SVZ to cortical plate in the embryonic brain slice culture. Thus, our result suggests a critical role of NMDAR in regulation of OPCs migration during CNS development by coupling to and activating the Tiam1/Rac1 pathway., (Copyright © 2013 Wiley Periodicals, Inc.)

RAS mutations occur frequently in human cancer and activated RAS signalling contributes to tumour development and progression. Apart from its oncogenic effects on cell growth, active RAS has tumour-suppressive functions via its ability to induce cellular senescence and apoptosis. RAS is known to induce p53-dependent cell cycle arrest, yet its effect on p53-dependent apoptosis remains unclear. We report here that apoptosis-stimulating protein of p53 (ASPP) 1 and 2, two activators of p53, preferentially bind active RAS via their N-terminal RAS-association domains (RAD). Additionally, ASPP2 colocalises with and contributes to RAS cellular membrane localisation and potentiates RAS signalling. In cancer cells, ASPP1 and ASPP2 cooperate with oncogenic RAS to enhance the transcription and apoptotic function of p53. Thus, loss of ASPP1 and ASPP2 in human cancer cells may contribute to the full transforming property of RAS oncogene.

Based on the survey data of macrobenthos in the intertidal flat of Luoyuan Bay in 2009, and by using Brey' s empirical formula, this paper estimated the macrobenthos secondary productivity, production/biomass (P/B) ratio, and their spatiotemporal distribution patterns in the flat. The annual secondary productivity and P/B ratio of the macrobenthos in the flat were estimated as 18.58 g AFDM (ash free dry mass) x m(-2) x a(-1) and 0.97, respectively, and the secondary productivity in the Spartina alterniflora marshes of the upper intertidal flat (8.97g AFDM x m(-2) a(-1)) was much lower than that in the bare flat of the lower intertidal zone (28.19 g AFDM x m(-2) x a(-1)). Since the introduction of S. alterniflora by the end of the 1980s, the secondary productivity of the macrobenthos in the flat had increased about 4 folds. Musculus senhousei, which inhabited in the lower bare flat, contributed 66.4% of the total macrobenthos secondary productivity in the entire intertidal flat. If the contribution from M. senhousei was not taken into account, the macrobenthos secondary productivity in the salt marshes would be significantly higher than that in the bare flat, and the macrobenthos secondary productivity in the intertidal flat would have less change. The successful colonization of M. senhousei was partly attributed to the changes of sediment composition enhanced by S. alterniflora due to its capability in trapping fine-grained materials; this species' feeding activities result in a remarkable increase of sediment chlorophyll a content. There was a significant positive correlation between the secondary productivity of macrobenthos and the sediment chlorophyll a and/or organic matter contents. These findings suggested that salt marshes had effects on the coastal wetland ecosystem via a number of physical and biological mechanisms.

Objectives: To translate the original English version of Geriatric Oral Health Assessment Index (GOHAI) into Mandarin Chinese and assess its reliability and validity for use among the elderly in inland China and to explore the factors associated with oral health-related quality of life (OHRQoL)., Methods:  The original English version of GOHAI was translated, back-translated and cross-culturally adapted. The psychometric properties of GOHAI-M were assessed in a sample of 263 people aged 60 years and over and OHRQoL was examined in 221 subjects using GOHAI-M. Multiple regression analysis was conducted., Results: Internal consistency of the GOHAI-M was excellent (Cronbach's α:0.81). Split-half reliability coefficient was 0.80, and item-scale correlation coefficient ranged from 0.25 to 0.71. Self-rated oral health was significantly associated with OHRQoL (r(s)=0.505, p<0.01). The relation coefficient between GOHAI-M and self-perceived need for dental treatment and number of missing teeth were 0.231 and -0.653, respectively (p<0.05). Multiple regression analysis found that better OHRQoL was significantly associated with better self-ratings of oral health (β=0.497, p=0.01), number of missing teeth (β=0.187, p<0.01) and life satisfaction (β=0.132, p<0.05)., Conclusion: The Mandarin Chinese version of GOHAI demonstrates acceptable reliability and validity. OHRQoL is associated with self-rated oral health, number of missing teeth and satisfaction with life., (© 2011 The Gerodontology Society and John Wiley & Sons A/S.)

Objective: To investigate the value of spatiotemporal image correlation (STIC) technique in the ventricular septal defect diagnosis., Methods: A total of 1,163 fetuses were enrolled in this study, diagnosed by fetal echocardiography and analyzed by STIC technique. We obtained effective STIC volumes from the fetus according to the Goncalves' report, and judged fetal cardiac structure from STIC volume information again with a double-blind method. Another echocardiography was obtained during neonatal or infant period as follow-up., Results: (1) As much as 1,062 cases were diagnosed to have normal fetal heart by fetal echocardiography, 43 cases had congenital heart disease without VSD, and 58 cases had VSD [21 cases (36.2%) were simple VSD and 37 cases (63.8%)were VSD with other heart malformation]. (2) Three fetal VSD cases (0.26%) were missed and one normal case was diagnosed as VSD after two-dimensional (2D) echocardiography. STIC technique corrected the diagnosis for two cases: one case of VSD after fetal 2D echocardiography was confirmed to be normal with STIC and neonatal heart examination; one case that was diagnosed as normal by fetal 2D echocardiography was confirmed to have VSD with STIC and neonatal heart examination., Conclusions: The special value of STIC technique in the diagnosis of VSD had been confirmed by this study, and it had been proved as the best additional method to fetal echocardiography.

Objective: To establish more effective diagnostic procedures to identify the characteristic features of abdominopelvic tuberculosis (APTB) mimicking advanced ovarian cancer., Methods: A retrospective review of 20 cases of APTB mimicking advanced ovarian cancer was undertaken., Results: The mean age of the patients was 28.9 ± 10.8 years. The main clinical manifestations were abdominal pain (45%) and distention (45%). CA125 level was elevated in 18 cases (90.0%). Pelvic mass in 18 patients (90.0%) and ascites in 12 patients (60.0%) were detected by using abdominal US. The bacteriologic cultures and cytological studies were all negative (10 cases, 100%). Laparotomy (17 cases) and laparoscopic evaluation (1 case) was performed with the presumptive diagnosis of advanced ovarian cancer except for 2 patients treated with diagnostic anti-TB chemotherapy. The common intra-operative findings were miliary nodules (14 cases, 77.8%) and widespread adhesion (10 cases, 55.6%). Intra-operative frozen section was obtained in 10 cases, and the typical tuberculosis tubercles were detected in all cases., Conclusion: APTB should be considered in all cases with pelvic mass, ascites and high levels of CA125, although clinical features and laboratory results specifically indicate neither ovarian malignancy nor APTB. Diagnostic laparotomy is a direct and safe method. To avoid extended surgery, the cases with APTB can be diagnosed through intra-operative frozen section in conjunction with clinical features.

A series of novel azobicyclo[3.3.0]octane derivatives were synthesized and evaluated as dipeptidyl peptidase 4 (DPP-4) inhibitors. The effort resulted in the discovery of inhibitor 2a, which exhibited excellent efficacies in an oral glucose tolerance test. Introduction of methyl group (2j) could prolong the inhibition of serum DPP-4 activity., (Copyright 2010 Elsevier Ltd. All rights reserved.)

The concentrations of EC, BC and dust aerosols were determined for atmospheric samples collected from an observation station in Xi'an, China. The results show that the averaged correlation coefficient between EC and BC was founded to be 0.72 with 0.81 (n = 49) in autumn, 0.70 (n = 112) in winter and 0.69 (n = 57) in spring, respectively. Absorption coefficients of dust aerosol were estimated to be 2.7 m(2) g(-1) in autumn and 4.4 m(2) g(-1) in winter. The comparison of absorption coefficients of dust aerosol with those of BC implies that BC is the principal light-absorbing aerosol over Xi'an atmosphere. By combining thermal analysis of elemental carbon and dust contents in the aerosol samples, however, the fraction of dust absorption to total light absorption is estimated to be 19% in autumn and 31% in winter, respectively.

Background: To explore the disparity in glycosylphosphatidylinositol phospholipase D (GPI-PLD) expression levels between mononuclear cells of chronic myeloid leukemia (CML) and healthy controls, and clarify the certain relation of GPI-PLD expression levels to complement mediated killing of leukemic cells., Methods: Competitive RT-PCR was used to detect quantitatively the GPI-PLD mRNA in mononuclear cells. GPI-anchored CD55 and CD59 were analyzed by flow cytometry and Western blotting. Complement-mediated lysis was assessed by staining method of trypan blue dye., Results: The GPI-PLD activities and their mRNA copies in CML patients were significantly lower than those in healthy adults. At the tenth day after treatment with bone marrow transplantation (BMT), the GPI-PLD activities and copies of GPI-PLD mRNA almost recovered to the expression levels of healthy subjects. The expression of both CD55 and CD59 in CML patients were significantly higher than those in healthy subjects. After treatment with insulin (10(-7) mol/l) plus glucose (16.7 mmol/l) for 48 h, the cellular GPI-PLD activity and mRNA levels in K562 cells derived from the leukemic cells of a CML patient all increased about 3-fold. Simultaneously, the GPI-anchored CD55 and CD59 on cell surfaces were released into the culturing medium, and the killing rate of complement-mediated K562 cell lysis increased almost 3 times., Conclusion: The decreased GPI-PLD expression may reduce the release of GPI-anchored CD55 and CD59 in leukemia cells and finally decrease complement mediated killing of these cells in chronic phase of CML.
