eIF3a is a N ⁶-methyladenosine (m⁶A) reader that regulates mRNA translation by recognizing m⁶A modifications of these mRNAs. It has been suggested that eIF3a may play an important role in regulating translation initiation via m⁶A during infection when canonical cap-dependent initiation is inhibited. However, the death of animal model studies impedes our understanding of the functional significance of eIF3a in immunity and regulation in vivo. In this study, we investigated the in vivo function of eIF3a using eIF3a knockout and knockdown mouse models and found that eIF3a deficiency resulted in splenic tissue structural disruption and multi-organ damage, which contributed to severe sepsis induced by Lipopolysaccharide (LPS). Ectopic eIF3a overexpression in the eIF3a knockdown mice rescued mice from LPS-induced severe sepsis. We further showed that eIF3a maintains a functional and healthy immune system by regulating B cell function and quantity through m⁶A modification of mRNAs. These findings unveil a novel mechanism underlying sepsis, implicating the pivotal role of B cells in this complex disease process regulated by eIF3a. Furthermore, eIF3a may be used to develop a potential strategy for treating sepsis.

In order to understand the prevalence and antimicrobial resistance of Enterococcus faeca-lis(E.faecalis)and Enterococcus faecium(E.faecium)isolated from human,pig and environ-ment in a Xinjiang pig farm,and to investigate the prevalence and potential harm of antimicrobial resistance genes,858 fecal samples from pig farm workers,anal swabs from pig and environment were collected for isolation,identification,antimicrobial susceptibility test and drug resistance gene detection.The results showed that 429 strains of E.faecalis and 222 strains of E.faecium were i-solated.The distribution of Enterococcus species varied among different sources.The isolation rate of E.faecalis was higher in pig anal swabs(73.1％,309/423)and human fecal samples(68.4％,26/38).E.faecium(42.3％,168/397)was mainly isolated from environmental samples.The drug resistance of E.faecalis and E.faecium isolated from pigs was similar to that of E.faecium isola-ted from environment.The drug resistance rates of E.faecalis and E.faecium isolated from pigs were more serious than those from humans to tetracycline,doxycycline,florfenicol and erythromy-cin,and they were more sensitive to ciprofloxacin and levofloxacin.More than 30.0％of E.faecalis and E.faecium isolated from pigs and environment were intermediate to linezolid.E.faecalis from three sources and E.faecium from environmental sources were mainly resistant to five drugs,while E.faecium from pigs was mainly resistant to six drugs.The detection rates of tet(M)and tet(L)genes in E.faecalis and E.faecium isolates from human,animal and environmental sources were more than 70.0％,which was consistent with the results of drug sensitivity.In addition,the cfr,optrA and poxtA genes that mediate oxazolidinone resistance were detected to varying extent.The cfr gene was only detected in four E.faecalis isolates from swine,one E.faecalis isolate from environment and two E.faecium isolates from environment.The positive rate of optrA gene in E.faecium isolated from pigs and environment was higher than that from humans,and the posi-tive rate was more than 60.0％.The positive rate of poxtA gene in E.faecium isolated from pigs and humans was more than 45.0％.The similar drug resistance situation suggests that there is the phenomenon of mutual contamination of drug-resistant bacteria in human-animal-environment.Therefore,we should consider from the perspective of one health,formulate comprehensive disin-fection and control programs,block the transmission route of drug-resistant strains and drug re-sistance genes between human-animal-environment,standardize the use of antibiotics,and reduce the enrichment of antibiotics in human-animal-environment,so as to reduce the risk of drug-resist-ant bacteria.

ObjectiveTo investigate the impact of yang deficiency syndrome on the progression to end-point events of diabetic kidney disease （DKD）. MethodsA retrospective study among patients with stage Ⅳ DKD admitted to Dongzhimen Hospital of Beijing University of Chinese Medicine from September 1st， 2016 to September 30th， 2021 was conducted. Data on the patients' general information， clinical indicators including duration of diabetes， duration of proteinuria， history of smoking and drinking， hemoglobin （HGB）， fasting blood glucose （FBG）， albumin （ALB）， serum creatinine （Scr）， urea nitrogen （BUN）， uric acid （UA）， cholesterol （TC） ， triglycerides （TG）， low-density lipoprotein （LDL）， 24-hour urine protein quantification （24h-UTP） and estimated glomerular filtration rate （eGFR）， and TCM syndromes including symptoms， tongue and pulse， and syndrome scores were collected. The patients were divided into exposure group （yang-deficiency group） and non-exposure group （non-yang-deficiency group）. The general information， clinical indicators and incidence rates of end-point events were compared， and the impact of yang deficiency syndrome on the end-point events of stage Ⅳ DKD was analyzed. Survival analysis was performed using Kaplan-Meier method， and multivariate Cox proportional risk models were used to identify independent predictors of end-point events. ResultsA total of 160 patients with stage Ⅳ DKD were included in the study， including 43 cases of yang deficiency syndrome and 117 cases of non-yang deficiency syndrome. Compared to those in the non-yang deficiency group， the waist circumference， BUN and the incidence of end-point events in the yang deficiency group were significantly higher （P＜0.05 or P＜0.01）. Spearman correlation analysis showed that yang deficiency syndrome was positively correlated with incidence of end-point events of stage Ⅳ DKD （r = 0.167， P = 0.035）. Furthermore， 24h-UTP and BUN levels were also positively correlated with end-point events in stage Ⅳ DKD patients （P＜0.01）， while ALB and HGB levels were negatively correlated （P＜0.01）. Kaplan-Meier survival curves showed that yang deficiency syndrome was associated with an increased risk of end-point events （Log Rank P = 0.011）. Moreover， 24h-UTP levels ≥3500 mg， BUN level ≥8 mmol/L， ALB level ＜30 g and HGB level ＜11 g were all associated with the increase of the risk of end-point events （P＜0.05 or P＜0.01）. Multivariate Cox regression analysis showed that yang deficiency syndrome was an independent risk factor for patients with stage Ⅳ DKD to progress into end-point events （HR = 2.36， 1.32 to 4.21； P = 0.004）， as well as 24h-UTP ≥ 3500 mg， BUN ≥ 8 mmol/L， HGB＜11 g and ALB＜30 g （P＜0.05 or P＜0.01）. ConclusionsFor stage Ⅳ DKD， patients with yang deficiency syndrome are more likely to have end-point events， which is an independent risk factor for the progression into end-point events.

Objective: To investigate cardiovascular disease (CVD) prevention status among residents with intra-urban migration in Central China, so as to provide insights into targeted prevention and control of CVD. Methods: Basic data of residents aged 35 to 75 years who participated in Early Screening and Comprehensive Intervention Project for CVD high-risk populations in Central China from September 2015 to August 2020 were collected. According to birth place, type of registered residence and current residence, residents were divided into four groups: local residents in old urban area, local residents in new urban area, other urban migrants and other rural migrants. The status of CVD primary and secondary prevention, were analysed by using a robust Poisson regression model. Results: A total of 76 513 residents were recruited, including 29 420 males (38.45%) and 47 093 females (61.55%), and had a mean age of (56.36±9.84) years. There were 45 087 (58.93%) local residents in old urban area, 23 868 (31.19%) local residents in new urban area, 5 668 (7.41%) other urban migrants and 1 890 (2.47%) other rural migrants. After adjusting for variables such as age, gender and educational level, the results of robust Poisson regression analysis showed that compared with local residents in old urban area, local residents in new urban area had lower compliance rates of non- or moderate-drinking (RR=0.987, 95%CI: 0.975-1.000) and healthy diet (RR=0.535, 95%CI: 0.365-0.782), lower proportion of using aspirin as primary prevention in CVD high-risk population (RR=0.616, 95%CI: 0.511-0.741), lower awareness (RR=0.873, 95%CI: 0.782-0.974) and control rates (RR=0.730, 95%CI: 0.627-0.849) of hypertension; other urban migrants had higher compliance rate of non-smoking (RR=1.045, 95%CI: 1.017-1.075); other rural migrants had lower proportion of using aspirin as primary prevention in CVD high-risk population (RR=0.826, 95%CI: 0.707-0.966). Conclusion The CVD primaryprevention among local residents in new urban area is relatively poor among four groups of residents in Central China, and key interventions are needed.
