Nonalcoholic fatty liver disease （NAFLD） is a multisystem disease associated with obesity， insulin resistance， and dyslipidemia and has a complex pathogenesis. Studies have shown that gut microbiota dysbiosis is closely associated with the onset of NAFLD， and traditional Chinese medicine treatment can improve the laboratory markers and clinical symptoms of NAFLD patients by regulating intestinal microbiota and its metabolites. This article elaborates on the association between NAFLD and gut microbiota， the involvement of gut microbiota dysbiosis in the pathogenesis of NAFLD， and the possible mechanism of traditional Chinese medicine treatment in improving NAFLD from the perspective of gut microbiota， in order to provide new ideas for the treatment of NAFLD.

Objective:To explore the effectiveness of modified objective structured clinical examination (OSCE) for evaluating the core competencies of new nurses on standardized training in neurosurgery.Methods:Thirty-seven new nurses on standardized training in neurosurgery were evaluated using a modified OSCE protocol that was focused on core competencies required for clinical nursing practice on the basis of a clinical case library, which consisted of diagnostic assessment upon entrance, process teaching evaluation during training, and outcome assessment upon exit, at five OSCE stations (nursing assessment, skill practice, clinical thinking, health education, and humanistic care). SPSS 26.0 was used to perform the t-test and rank sum test. Results:The nurses highly recognized the effectiveness of modified OSCE and were largely satisfied with teaching. There were significant differences at entrance and exit in terms of the mean OSCE score ( t=24.21, P<0.001), independent learning ability ( t=10.29, P<0.001), and the scores of core competencies—good personal traits ( Z=5.24, P<0.001), clinical nursing ability ( Z=5.07, P<0.001), support and interpersonal communication ability ( Z=5.12, P<0.001), critical clinical thinking ability ( Z=5.17, P<0.001), professional construction and self-development ( Z=5.05, P<0.001), and the total score ( Z=5.27, P<0.001). Conclusions:The modified OSCE can comprehensively evaluate the core competencies of new nurses in neurosurgery standardized training, with good feasibility and effectiveness, which provides a reference for teaching management of standardized training programs.

Objective To evaluate the efficacy and safety of brexpiprazole in treating acute schizophrenia.Methods Patients with schizophrenia were randomly divided into treatment group and control group.The treatment group was given brexpiprozole 2-4 mg·d-1 orally and the control group was given aripiprazole 10-20 mg·d-1orally,both were treated for 6 weeks.Clinical efficacy of the two groups,the response rate at endpoint,the changes from baseline to endpoint of Positive and Negative Syndrome Scale(PANSS),Clinical Global Impression-Improvement(CGI-S),Personal and Social Performance scale(PSP),PANSS Positive syndrome subscale,PANSS negative syndrome subscale were compared.The incidence of treatment-related adverse events in two groups were compared.Results There were 184 patients in treatment group and 186 patients in control group.After treatment,the response rates of treatment group and control group were 79.50％(140 cases/184 cases)and 82.40％(150 cases/186 cases),the scores of CGI-I of treatment group and control group were(2.00±1.20)and(1.90±1.01),with no significant difference(all P＞0.05).From baseline to Week 6,the mean change of PANSS total score wese(-30.70±16.96)points in treatment group and(-32.20±17.00)points in control group,with no significant difference(P＞0.05).The changes of CGI-S scores in treatment group and control group were(-2.00±1.27)and(-1.90±1.22)points,PSP scores were(18.80±14.77)and(19.20±14.55)points,PANSS positive syndrome scores were(-10.30±5.93)and(-10.80±5.81)points,PANSS negative syndrome scores were(-6.80±5.98)and(-7.30±5.15)points,with no significant difference(P＞0.05).There was no significant difference in the incidence of treatment-related adverse events between the two group(69.00％vs.64.50％,P＞0.05).Conclusion The non-inferiority of Brexpiprazole to aripiprazole was established,with comparable efficacy and acceptability.

BACKGROUND: Butylphthalide (NBP) and edaravone (EDV) injection are common acute ischemic stroke medications in China, but there is a lack of large real-world safety studies on them. This study aimed to determine the incidence of adverse events, detect relevant safety signals, and assess the risk factors associated with these medications in real-world populations. METHODS: In this study, data of acute ischemic stroke patients were extracted from the electronic medical record database of six tertiary hospitals between January 2019 and August 2021. Baseline confounders were eliminated using propensity score matching. The drugs' safety was estimated by comparing the results of 24 laboratory tests standards on liver function, kidney function, lipid level, and coagulation function. The drugs' relative risk was estimated by logistic regression. A third group with patients who did not receive NBP or EDV was constructed as a reference. Prescription sequence symmetry analysis was used to evaluate the associations between adverse events and NBP and EDV, respectively. RESULTS: 81,292 patients were included in this study. After propensity score matching, the NBP, EDV, and third groups with 727 patients in each group. Among the 15 test items, the incidence of adverse events was lower in the NBP group than in the EDV group, and the differences were statistically significant. The multivariate logistic regression equation revealed that NBP injection was not a promoting factor for abnormal laboratory test results, whereas EDV had statistically significant effects on aspartate transaminase, low-density lipoprotein cholesterol and total cholesterol. Prescription sequence symmetry analysis showed that NBP had a weak correlation with abnormal platelet count. EDV had a positive signal associated with abnormal results in gamma-glutamyl transferase, alanine aminotransferase, aspartate aminotransferase, prothrombin time, and platelet count. CONCLUSIONS In a large real-world population, NBP has a lower incidence of adverse events and a better safety profile than EDV or other usual medications.

Aim To observe the effect of Gupi Xiaoji Decoction (GPXJY) on the structure and function of mitochondria of human hepatoma cell HepG2 cells and explore its possible mechanism. Methods CCK8 was used to detect cell proliferation, Mito-Tracker Green fluorescence staining was used to observe the mitochondrial structure, flow cytometry was used to detect the membrane potential, Elisa was used to detect the ATP content, fluoroscopic electron microscopy was used to observe the microstructure changes, and high-content screening(HCS) was used to detect the related proteins. Results Fluorescence staining showed that GPXJY damaged the mitochondria of HepG2 cells and decreased the content of ATP. The results of flow cytometry showed that GPXJY could reduce the mitochondrial membrane potential of HepG2 cells. The results of electron microscope showed that GPXJY made the mitochondria of cancer cells swell and so on. HCS found that GPXJY significantly reduced the average fluorescence intensity of Bcl-2 in HepG2 cells, and significantly increased the average fluorescence intensity of apoptosis promoting proteins Bax, cytochrome-c, caspase-3 and cleaved-caspase-3, which was statistically significant. Conclusion GPXJY can regulate the structure and function of mitochondria in HepG2 cells.

Objective: To investigate the incidence of chromosome polymorphisms and their influence on semen quality and sperm DNA integrity in male patients receiving in vitro fertilization/intracytoplasmic sperm injection (IVF/ICSI). METHODS: We retrospectively analyzed the chromosomal karyotypes and the types and incidence rate of chromosome polymorphisms in 2 370 male patients undergoing IVF/ICSI between June 2016 and June 2018. We classified the patients into groups A (with variation in the secondary constriction region in the autosomal long arm), B (with variation in the short arm of the D/G group chromosomes), C (with interbrachial inversion of chromosome 9) and D (with Y chromosome polymorphisms), and compared the semen parameters and sperm DNA fragmentation indexes (DFI) between the patients with chromosome polymorphisms and those with normal chromosomes. RESULTS: Totally, 154 (6.50%) of the patients undergoing IVF/ICSI were found with chromosome polymorphisms, including 34 cases of secondary constriction variation in the long arm of the autosome (1.43% ［34/2 370］, 22.08% ［34/154］), 82 cases of short arm polymorphisms of the D/G group chromosomes (3.46% ［82/2 370］, 53.25% ［82/154］), 26 cases of interbrachial inversion of chromosome 9 (1.10% ［26/2 370］, 16.88% ［26/154］), 10 cases of Y chromosome polymorphisms (0.42% ［10/2 370］, 6.50% ［10/154］), and 2 cases of mixed chromosome polymorphisms (0.08% ［2/2 370］, 1.42% ［2/154］). The total sperm count was lower in group D than in the other polymorphism groups and the normal chromosome group, but with no statistically significant difference among the five groups (P > 0.05). The sperm progressive motility was also lower in group D than in the other five groups, with statistically significant difference from group B (27.5 ± 13.5 vs. 41.5 ± 21.1, P = 0.027), but not from the other groups (P > 0.05). No statistically significant difference was observed in the sperm DFI between the polymorphism groups and the normal chromosome group (P > 0.05), or among the polymorphism groups (P > 0.05). The proportion of normal semen was lower in group D than in the other four groups, but with no statistically significant difference among the five groups (P > 0.05). The incidence rate of asthenospermia was higher in group D than in the other four groups, but with no statistically significant difference among the five groups (P > 0.05), and so was that of oligoasthenospermia, with statistically significant difference from the normal chromosome group (30.0% vs 8.0%, P = 0.041), but not from the other polymorphism groups (P > 0.05). CONCLUSIONS Short arm polymorphisms of the D/G group chromosomes are the most common type of chromosome polymorphisms in male patients undergoing IVF/ICSI. Polymorphisms of the Y chromosome have a negative effect on semen quality, while those of the other chromosomes do not significantly affect semen quality and sperm DNA integrity.

BACKGROUND: Desminopathy, a hereditary myofibrillar myopathy, mainly results from the desmin gene (DES) mutations. Desminopathy involves various phenotypes, mainly including different cardiomyopathies, skeletal myopathy, and arrhythmia. Combined with genotype, it helps us precisely diagnose and treat for desminopathy. METHODS: Sanger sequencing was used to characterize DES variation, and then a minigene assay was used to verify the effect of splice-site mutation on pre-mRNA splicing. Phenotypes were analyzed based on clinical characteristics associated with desminopathy. RESULTS: A splicing mutation (c.735+1G>T) in DES was detected in the proband. A minigene assay revealed skipping of the whole exon 3 and transcription of abnormal pre-mRNA lacking 32 codons. Another affected family member who carried the identical mutation, was identified with a novel phenotype of desminopathy, non-compaction of ventricular myocardium. There were 2 different phenotypes varied in cardiomyopathy and skeletal myopathy among the 2 patients, but no significant correlation between genotype and phenotype was identified. CONCLUSIONS We reported a novel phenotype with a splicing mutation in DES, enlarging the spectrum of phenotype in desminopathy. Molecular studies of desminopathy should promote our understanding of its pathogenesis and provide a precise molecular diagnosis of this disorder, facilitating clinical prevention and treatment at an early stage.

To introduce the application status of network Meta-analysis( NMA) in the field of traditional Chinese medicine,and to discuss the application value of NMA in the field of traditional Chinese medicine,this study comprehensively reviewed the systematic reviews with application of NMA in the field of traditional Chinese medicine. CNKI,Wan Fang,Sino Med,VIP,Embase,PubMed and Cochrane Library and the reference list of previous studies were searched. The AMSTAR scale was used to evaluate the quality of literature methodology,and PRISMA-NMA checklist was used to measure the degree of report specification. Overall,122 articles were included,including 80 in Chinese and 42 in English. The included studies centered on cancer,bone and joint disease,cardiovascular disease,respiratory disease,mental disease and digestive disease. Additionally,the intervention can be categorized into three groups,traditional Chinese medicine injection,oral Chinese medicine or prescription,and traditional physical therapy including acupuncture.Nearly one-third of the researches' intervention program is aimed at comparing the effect of Chinese and Western combined therapy and monotherapy. The overall methodology quality grade is medium and the report quality is average,with methodology reporting and result reporting especially need to be improved. The subgroup analysis shows that the methodology quality of the English literatures is evidently higher than Chinese literatures,and the quality of the literatures published after 2015 is higher than those published in or before 2015.This study indicates that the NMA can compare multiple treatments simultaneously,which accords with characteristics of the clinical practice in traditional Chinese medicine that is complex and individual. NMA in the field of traditional Chinese medicine is still in the process of development. With higher level of quality control and reporting as well as the improvement of the statistical methodology and the accumulation of original researches,NMA application in the field of traditional Chinese medicine will be promising.

Background: Disease-modifying therapy is the standard treatment for patients with multiple sclerosis (MS) in remission. The primary objective of the current analysis was to assess the efficacy and safety of two teriflunomide doses (7 mg and 14 mg) in the subgroup of Chinese patients with relapsing MS included in the TOWER study. Methods: TOWER was a multicenter, multinational, randomized, double-blind, parallel-group (three groups), placebo-controlled study. This subgroup analysis includes 148 Chinese patients randomized to receive either teriflunomide 7 mg (n = 51), teriflunomide 14 mg (n = 43), or placebo (n = 54). Results: Of the 148 patients in the intent-to-treat population, adjusted annualized relapse rates were 0.63 (95% confidence interval [CI]: 0.44, 0.92) in the placebo group, 0.48 (95% CI: 0.33, 0.70) in the teriflunomide 7 mg group, and 0.18 (95% CI: 0.09, 0.36) in the teriflunomide 14 mg group; this corresponded to a significant relative risk reduction in the teriflunomide 14 mg group versus placebo (-71.2%, P = 0.0012). Teriflunomide 14 mg also tended to reduce 12-week confirmed disability worsening by 68.1% compared with placebo (hazard ratio: 0.319, P = 0.1194). There were no differences across all treatment groups in the proportion of patients with treatment-emergent adverse events (TEAEs; 72.2% in the placebo group, 74.5% in the teriflunomide 7 mg group, and 69.8% in the teriflunomide 14 mg group); corresponding proportions for serious adverse events were 11.1%, 3.9%, and 11.6%, respectively. The most frequently reported TEAEs with teriflunomide versus placebo were neutropenia, increased alanine aminotransferase, and hair thinning. Conclusions: Teriflunomide was as effective and safe in the Chinese subpopulation as it was in the overall population of patients in the TOWER trial. Teriflunomide has the potential to meet unmet medical needs for MS patients in China.

Objective To investigate the effects of bradykinin (BK) on the proliferation of rabbit corneal endothehal ceils (RCECs) and the expression of tight junction-related proteins zonula occludens-1 (ZO-1) and zonula occludens-1-associated nucleic-acid-binding protein (ZONAB),and to explore the underlying mechanisms of BK on cell proliferation in corneal endothelium.Methods RCECs at logarithmic growth phase were treated with different concentrations of BK (0.01,0.1,1,10 μmol · L-1) BK group,with the controls left untreated.Morphological changes of cells in each group were examined under phase-contrast microscope,and MTT assays were used to detect cell proliferation at 24 h,48 h,72 h,96 h after BK treatment.And,at 72 h,the expression levels of ZO-1 and ZONAB protein were determined by Western blot.Results After 72 h of treatment,the cells in each group were fused into pieces and closely linked into a monolayer;but after 96 h,the growth of the cells was restricted,with the intercellular space become larger and the cells exfoliated.Compared with the control group,BK induced a significant increase of absorbance value and cell viability,and the differences were statistically significant (all P ＜ 0.001),and the promoting effects showed a concentration-dependent manner,and 1 μmol · L-1 BK demonstrated the strongest regulative effect (P ＜ 0.001).Western blot results showed that BK upregulated the expression of ZO-1 and ZONAB protein in a concentration-dependent manner.Conclusion BK can stimulate the proliferation of RCECs in a time-and concentration-dependent manner,and the mechanisms are probably associated with ZO-1/ZONAB-mediated signaling pathway.
