Emerging evidence suggests that dysbiosis of the gut microbiota is associated with the pathogenesis of Parkinson's disease (PD), a prevalent neurodegenerative disorder. The microbiota-gut-brain axis plays a crucial role in the development and progression of PD, and numerous studies have demonstrated the potential therapeutic benefits of modulations in the intestinal microbiota. This review provides insights into the characterization of the gut microbiota in patients with PD and highlights associations with clinical symptoms and underlying mechanisms. The discussion underscores the increased influence of the gut microbiota in the pathogenesis of PD. While the relationship is not fully elucidated, existing research demonstrates a strong correlation between changes in the composition of gut microbiota and disease development, and further investigation is warranted to explain the specific underlying mechanisms.

Objective To evaluate the efficacy,safety and cost-effectiveness of dorzagliatin in the treatment of type 2 diabetes mellitus using a rapid health technology assessment,and to provide medical evidence for clinical decision-making.Methods PubMed,Embase,Cochrane Library,CNKI,Wanfang Data,SinoMed and relevant health technology assessment(HTA)websites and databases were searched to collect systematic reviews/Meta-analysis,pharmacoeconomic literature and HTA reports of dorzagliatin in the treatment of type 2 diabetes from inception to July 20,2024.Two reviewers independently screened literature,extracted date and assessed quality.The results were qualitatively described and analyzed.Results A total of 6 studies were included,including 5 systematic reviews/Meta-analysis and a pharmacoeconomic study.In terms of efficacy compared with placebo,dorzagliatin significantly reduced glycated hemoglobin(HbA1c),fasting plasma glucose,2-hour postprandial blood glucose and insulin resistance index(P＜0.05),improved HbA1c compliance rate in terms of safety,dorzagliatin,and enhanced homeostasis model assessment-β(P＜0.05),significantly increased total cholesterol,triglyceride,body weight and body mass index(P＜0.05).In terms of safety,the total incidence of adverse reactions of dorzagliatin was slightly higher than that of the placebo group(P＜0.05).However,there was no significant difference in the incidence of severe adverse reactions between the two groups(P＞0.05),and there was no significant increase in the incidence of hyperlipidemia and hypoglycemia(P＞0.05).In terms of economy,the treatment of dorzagliatin combined with metformin has a long-term cost-utility advantage,with an economic probability of nearly 70％.Conclusion Compared with placebo,dorzagliatin has a good overall efficacy and safety in the treatment of type 2 diabetes.In terms of safety,the total incidence of adverse reactions of dorzagliatin was slightly higher than that of placebo.In terms of economy,compared with metformin alone,dorzagliatin combined with metformin has economic advantages.However,there is a lack of head-to-head comparisons of doxorubicin with other classes of glucose-lowering medications,and none of the included studies described long-term cardiac,cerebral,or renal benefits,which limits the comprehensive evaluation of the efficacy and safety of dorzagliatin.

Objective:This study aimed to investigate the association between genetic factors and the risk of developing treatment-resistant depression (TRD), as well as the efficacy of modified electroconvulsive therapy (MECT), with a specific focus on identifying gene polymorphisms that can differentiate TRD from non-TRD.Methods:This case-control study included inpatients with depression in Adult Psychiatry Department, Affective Disorders Department and Geriatrics Department of Guangzhou Medical University Affiliated Brain Hospital from January 2023 to June 2024, as well as healthy individuals undergoing physical examinations in the outpatient department. Matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF MS) was utilized to genotype 16 loci across 10 candidate genes in 107 non-TRD patients, 101 TRD patients and 281 healthy controls. Hardy-Weinberg equilibrium testing, genotype frequency distribution analysis, and genetic association studies were conducted using PLINK software. Univariate binary logistic regression under a dominant model was performed using R software to analyze gene loci associated with non-TRD and TRD.Results:All 16 gene loci in the control group, the TRD group, and the non-TRD group were found to be in Hardy-Weinberg equilibrium ( P>0.05). No significant differences were observed in the genotype distribution of these gene loci across the groups ( P>0.05). Univariate binary logistic regression analysis revealed that individuals with depression carrying the HTR2A-rs7997012 G allele had a significantly lower risk of developing TRD ( OR=0.26, P=0.047). Among the patients receiving MECT, the proportion of G allele carriers who showed improvement at 2, 4, and 6 weeks of treatment was significantly higher compared to those who did not show improvement (96.61% vs. 80.95%, 96.55% vs. 50.00%, 96.59% vs. 46.15%, respectively), with χ2 values of 6.743, 29.295, and 32.300, respectively, and all P values <0.05. Conclusion:The HTR2A-rs7997012 polymorphism may represent a genetic distinction between TRD and non-TRD. Depressed patients with the rs7997012 G allele have a reduced likelihood of developing TRD, moreover, MECT demonstrates superior efficacy in this patient population.

Objective:To assess the efficacy and safety profile of antaitasvir phosphate combined with yiqibuvir in the treatment of chronic hepatitis C (CHC) of various genotypes, without cirrhosis or with compensated cirrhosis.Methods:394 cases with CHC from 22 centers were collected from October 2021 to April 2023. They were randomly assigned to receive either the experimental drugs (antaitasvir phosphate 100 mg+yiqibuvir 600 mg) or placebo treatment in a 3∶1 ratio. The patients were administered drugs once a day for 12 consecutive weeks, and then followed up for 24 weeks after treatment cessation. All subjects were unblinded at the four-week follow-up following drug discontinuation, with the experimental drug group continuing to complete subsequent post-discontinuation follow-up. The placebo group was switched to receive the experimental drugs for a repeated 12-week treatment period and followed up for another 24 weeks after discontinuation of the drug (placebo delayed treatment phase).The sustained virologic response rate (SVR12) was observed for subjects in the double-blind phase and the placebo delayed-treatment phase at 12 weeks after treatment cessation.Virological resistance analysis was performed on subjects who failed treatment. The primary efficacy endpoint was SVR12. The number and percentage of subjects who achieved "HCV RNA
