Depression is a common mental disorder with adverse effects on human health and quality of life.Although its pathogenesis remains unclear,numerous recent studies have indicated a close association between depression and mitochondrial dysfunction.This review explores the critical role of mitochondrial dysfunction in the pathogenesis of depression from the aspects of energy metabolism disorders,oxidative stress and inflammatory responses,mitochondrial DNA damage and mutations,and the imbalance of the mitochondrial quality control systems.We also summarize recent advances in the use of traditional Chinese medicine(TCM)to treat depression by regulating mitochondrial function.The findings show the potential of TCM in enhancing mitochondrial energy metabolism,reducing oxidative stress and inflammatory responses,improving mitochondrial DNA,and modulating the mitochondrial quality control systems,including for the in-depth study of the pathogenesis of depression and its treatment with TCM.

Delirium has a high incidence and is associated with a poor patient prognosis.The pathogenesis of delirium is still unclear.Although antipsychotic drugs are the main intervention in clinical practice,there are currently no drugs that can definitively improve the long-term health-related quality of life in patients with delirium.In this study,we review research on the associations between epigenetic modifications such as non-coding RNAs,DNA methylation,and histone acetylation and the development of delirium,with the aim of providing information to support clinical decisions on the early identification and diagnosis of delirium,as well as its treatment and prognosis and the development of relevant targeted drugs.

Objective:To explore the genetic and clinical characteristics of Guizhou patients with enlarged vestibular aqueduct（EVA） syndrome through combined SLC26A4 variant analysis and clinical phenotype analysis. Methods:Seventy-two EVA patients underwent comprehensive genetic testing using a multiplex PCR-based deafness gene panel and next-generation sequencing（NGS）. The audiological and temporal bone imaging characteristics were compared across mutation subtypes. Results:A total of 27 pathogenic loci of SLC26A4 were detected in 72 patients, including c.919-2A>G in 79.2%（57/72）. A novel deletion（c.1703_1707+6del） was discovered. Among 65 cases, truncated mutations were 89.2%（58/65）, 52.3%（34/65）, 28（43.1%） and 7（10.8%）. No significant differences were observed in the midpoint diameter of the vestibular aqueduct and the incidence of incomplete partitioning typeⅡ（IP-Ⅱ） of the cochlea among the three groups of patients. Moreover, there was no difference in the midpoint diameter of different vestibular pipes or the combination with IP-Ⅱ. Conclusion:The most common mutation site of SLC26A4 in EVA patients in Guizhou is c.919-2A>G, though genotype-phenotype correlations remain elusive. The detection of 27 mutation sites and the discovery of new mutation sites suggested the precise diagnostic significance of NGS technology in EVA patients in Guizhou.

With the recent ongoing autumn/winter 2022 COVID-19 wave and the adjustment of public health control measures, there have been widespread SARS-CoV-2 infections in Chinese mainland. Here we have analyzed 369 viral genomes from recently diagnosed COVID-19 patients in Shanghai, identifying a large number of sublineages of the SARS-CoV-2 Omicron family. Phylogenetic analysis, coupled with contact history tracing, revealed simultaneous community transmission of two Omicron sublineages dominating the infections in some areas of China (BA.5.2 mainly in Guangzhou and Shanghai, and BF.7 mainly in Beijing) and two highly infectious sublineages recently imported from abroad (XBB and BQ.1). Publicly available data from August 31 to November 29, 2022 indicated an overall severe/critical case rate of 0.035% nationwide, while analysis of 5706 symptomatic patients treated at the Shanghai Public Health Center between September 1 and December 26, 2022 showed that 20 cases (0.35%) without comorbidities progressed into severe/critical conditions and 153 cases (2.68%) with COVID-19-exacerbated comorbidities progressed into severe/critical conditions. These observations shall alert healthcare providers to place more resources for the treatment of severe/critical cases. Furthermore, mathematical modeling predicts this autumn/winter wave might pass through major cities in China by the end of the year, whereas some middle and western provinces and rural areas would be hit by the upcoming infection wave in mid-to-late January 2023, and the duration and magnitude of upcoming outbreak could be dramatically enhanced by the extensive travels during the Spring Festival (January 21, 2023). Altogether, these preliminary data highlight the needs to allocate resources to early diagnosis and effective treatment of severe cases and the protection of vulnerable population, especially in the rural areas, to ensure the country's smooth exit from the ongoing pandemic and accelerate socio-economic recovery.

Objective To delve into the causal relationship between 211 gut microbiota and sepsis employing bidirectional Mendelian randomization(MR).Methods The gut microbiota genome-wide association study(GWAS)data from the Microbiome Genetics Consortium(MiBioGen,n = 18 340)and sepsis GWAS data from the FinnGen(n = 286 146)were harnessed for this study.Initially,single nucleotide polymorphisms(SNP)significantly associated with the relative abundance of 211 gut microbiota taxa were identified as instrumental variables using predefined selection criteria.The primary analytical approach was characterized by the application of inverse variance weighting(IVW),with the effect measure represented by the odds ratio(OR)to assess the results of MR.To ensure precision and reliability,analyses were conducted,including leave-one-out analysis,heterogeneity testing,and tests for pleiotropy at both coherent and incoherent levels.Results The increased risk of sepsis was associated with the elevated abundance of Collinsella[OR = 1.28,95%confidence interval(95%CI)was 1.06-1.56,P = 0.01]and Ruminococcus(OR = 1.19,95%CI was 1.05-1.35,P = 0.005).Furthermore,a protective effect against the development of sepsis was observed in association with the increased abundance of Prevotella(OR = 0.88,95%CI was 0.79-0.97,P = 0.01)and Firmicutes(OR = 0.86,95%CI was 0.75-0.996,P = 0.04).No obvious heterogeneity and irrelevant level pleiotropy were detected.Conclusion Collinsella and Ruminococcus increase the risk of sepsis,while Prevotella and Firmicutes have protective effects against sepsis.
