Objective To investigate the causal relationship between gut microbiota and idiopathic pulmonary fibrosis (IPF). Methods Genome-wide association studies (GWAS) data of gut microbiota and IPF were obtained from MiBioGen and IEU OpenGWAS, respectively. Instrumental variables were screened by means of significance, linkage disequilibrium, weak instrumental variable screening, and removal of confounding factors (genetics, smoking, host characteristics). Inverse variance weighted (IVW) was used as the main Mendelian randomization (MR) analysis method, and the weighted median, simple mode, MR-Egger, and weighted mode were used to perform MR to reveal the causal effect of gut microbiota and IPF. The Cochrane's Q, leave-one-out, MR-Egger-intercept, and Mendelian randomization pleiotropy residual sum and outlier (MR-PRESSO) and Steiger tests were used to analyze the heterogeneity, horizontal pleiotropy, outliers, and directionality, respectively. Results IVW analysis results showed that Actinobacteria [OR=1.773, 95%CI (1.323, 2.377), P<0.001], Erysipelatoclostridium [OR=2.077, 95%CI (1.107, 3.896), P=0.023], and Streptococcus [OR=1.35, 95%CI (1.100, 1.657), P=0.004] could increase the risk of IPF. Bifidobacterium [OR=0.668, 95%CI (0.620, 0.720), P<0.001], Ruminococcus [OR=0.434, 95%CI (0.222, 0.848), P=0.015], and Tyzzerella [OR=0.479, 95%CI (0.304, 0.755), P=0.001] could reduce the risk of IPF. No significant heterogeneity, horizontal pleiotropy, outliers, and reverse causality were found. Conclusion Actinobacteria, Erysipelatoclostridium and Streptococcus may increase the risk of IPF, while Bifidobacterium, Ruminococcus and Tyzzerella may reduce the risk of IPF. Regulation of the above gut microbiota may become a new direction in the study of the pathogenesis of IPF.

Lipocalin-2 (LCN2), a member of the human lipocalin family, has been demonstrated to be closely associated with diabetes, cardiovascular diseases, and renal disorders. Recent studies have indicated that LCN2 plays a significant regulatory role in the pathogenesis and progression of various neurological diseases by mediating pathways such as inflammation, oxidative stress, and ferroptosis. This article reviews the research advancements on the mechanism of LCN2 in neurological disorders, including cerebrovascular diseases, cognitive impairment disorders, Parkinson's disease, depression, and anxiety disorders, aiming to enhance clinical understanding.

The areas of S. japonicum-infected snail habitats appeared an average annual reduction of 47.09% in Wuhan City from 2005 to 2023 [AAPC = -47.09%, 95% CI: (-52.92%, -38.26%), P < 0.01], with two joinpoints in 2011 and 2014, respectively, and the tendency towards a decline showed statistical significance during the period from 2011 through 2014 [APC = -97.27%, 95% CI: (-98.65%, -88.06%), P < 0.01]. The areas of snail habitats in inner embankments appeared an average annual reduction of 4.45% in Wuhan City from 2005 to 2023 [AAPC = -4.45%, 95% CI: (-5.18%, -3.82%), P < 0.01], with three joinpoints in 2011, 2015 and 2018, respectively, and statistical significance was seen in the tendency towards a decline during the period from 2005 through 2011 [APC = -16.38%, 95% CI: (-20.15%, -14.25%), P < 0.01]. In addition, the actual areas of snail habitats appeared an average annual reduction of 2.65% in Wuhan City from 2005 to 2023 [AAPC = -2.65%, 95% CI: (-2.89%, -2.40%), P < 0.01], with a joinpoint in 2013, and the tendency towards a decline showed statistical significance during the period from 2013 through 2023 [APC = -4.06%, 95% CI: (-4.66%, -3.58%), P < 0.01]. Conclusions The integrated schistosomiasis control programme achieved significant effectiveness in Wuhan City from 2005 to 2023, with a tendency towards a decline in morbidity due to schistosomiasis in humans and livestock and snail status. The integrated schistosomiasis control strategy with emphasis on management of the source of S. japonicum infections should continue to be implemented to consolidate the schistosomiasis control achievements and achieve the goal of schistosomiasis elimination in the city.

Diseases caused by animal virus infection seriously restricts the healthy development of animal husbandry.In-depth study of the molecular mechanism of viral replication and pathogenesis will provide theoretical basis for screening vaccine and drug targets.N6-methyladenosine(m6 A)modification occurs extensively in viral and host transcriptomes and affects viral replication and pathogenicity by regulating gene expression,which acts as a novel regulator of gene expression in addition to DNA and protein modifications.Insight into the regulatory molecular mechanism of m6 A modification in virus infection is the research hotspots and frontiers.In recent years,there are re-ports of alternation of the m6 A modification-associated epitranscriptomes and related function a-nalysis during virus infection.Here,we summarize the alternation of the epitranscriptomes induced by African swine fever virus(ASFV),porcine reproductive and respiratory syndrome virus(PRRSV),porcine epidemic diarrhoea virus(PEDV),cestode virus(CSFV),porcine pseudorabies virus(PRV),Marek's disease virus(MDV),Newcastle disease virus(NDV),avian leukaemia virus(ALV)and duck hepatitis A virus(DHAV)infection,and the subsequent effects on viral replica-tion and pathogenicity.We also discuss the potential role and molecular mechanism of m6 A modification in animal virus replication and pathogenesis,which will contributes to the prevention and control for animal disease.

Background and Aims:Unplanned reoperation is a critical indicator for evaluating the quality of surgical treatment and prognosis in patients with gastrointestinal perforation.Identifying its underlying causes,recognizing relevant risk factors,and developing effective preventive strategies are essential for optimizing treatment outcomes and improving patient prognosis.This study aimed to investigate the causes and risk factors of unplanned reoperation following surgery for gastrointestinal perforation,in order to provide clinical guidance for targeted interventions.Methods:The clinical data of 303 patients who underwent surgery for gastrointestinal perforation at the Department of General Surgery,Shijiazhuang People's Hospital,from January 2020 to July 2023,were retrospectively analyzed.Among them,218 were males and 85 were females,with a mean age of(61.05±17.95)years.Seventeen patients experienced unplanned reoperations after operation,while 286 did not.Univariate analysis and multivariate Logistic regression were performed to identify the risk factors associated with unplanned reoperation.A predictive model was developed and its performance was assessed using the receiver operating characteristic(ROC)curve.Results:Among the 17 patients who underwent unplanned reoperation,14 were males and 3 were females,with a mean age of(65.76±15.11)years.The primary causes of reoperation included postoperative fistula(7 cases),postoperative bleeding(4 cases),surgical site infection(2 cases),wound dehiscence(2 cases),and stoma-related complications(2 cases).Univariate analysis indicated that gender,comorbidities,hypoproteinemia,history of abdominal surgery,ASA score,surgical grade,and disease duration were significantly associated with unplanned reoperation(all P<0.05).Multivariate Logistic regression revealed that male gender(OR=99.62,95%CI=4.90-2 025.29,P<0.05),hypoproteinemia(OR=8.59,95%CI=1.81-40.91,P<0.05),history of abdominal surgery(OR=17.28,95%CI=3.42-87.32,P<0.05),higher ASA score(OR=11.89,95%CI=2.73-51.72,P<0.05),higher surgical grade(OR=17.15,95%CI=2.47-118.93,P<0.05),and longer disease duration(OR=1.04,95%CI=1.02-1.07,P<0.05)were independent risk factors.The ROC curve analysis showed that the predictive model constructed based on the above factors had a sensitivity of 0.90,a specificity of 0.88,and an area under the curve of 0.94(95%CI=0.88-0.99,P<0.001).Conclusion:The leading causes of unplanned reoperation after gastrointestinal perforation surgery are postoperative fistula and bleeding.Male gender,hypoproteinemia,and other high-risk factors significantly increase the likelihood of reoperation.Although most such surgeries are performed emergently,comprehensive preoperative assessment of relevant risk factors is crucial to reduce the incidence of unplanned reoperation,and improve patient outcomes.

Objective:To investigate the rates of low disease activity and clinical remission in patients with systemic lupus erythematosus(SLE)in a real-world setting,and to analyze the related factors of low disease activity and clinical remission.Methods:One thousand patients with SLE were enrolled from 11 teaching hospitals.Demographic,clinical and laboratory data,as well as treatment regimes were collec-ted by self-completed questionnaire.The rates of low disease activity and remission were calculated based on the lupus low disease activity state(LLDAS)and definitions of remission in SLE(DORIS).Charac-teristics of patients with LLDAS and DORIS were analyzed.Multivariate Logistic regression analysis was used to evaluate the related factors of LLDAS and DORIS remission.Results:20.7％of patients met the criteria of LLDAS,while 10.4％of patients achieved remission defined by DORIS.Patients who met LLDAS or DORIS remission had significantly higher proportion of patients with high income and longer disease duration,compared with non-remission group.Moreover,the rates of anemia,creatinine eleva-tion,increased erythrocyte sedimentation rate(ESR)and hypoalbuminemia was significantly lower in the LLDAS or DORIS group than in the non-remission group.Patients who received hydroxychloroquine for more than 12 months or immunosuppressant therapy for no less than 6 months earned higher rates of LLDAS and DORIS remission.The results of Logistic regression analysis showed that increased ESR,positive anti-dsDNA antibodies,low level of complement(C3 and C4),proteinuria,low household in-come were negatively related with LLDAS and DORIS remission.However,hydroxychloroquine usage for longer than 12 months were positively related with LLDAS and DORIS remission.Conclusion:LLDAS and DORIS remission of SLE patients remain to be improved.Treatment-to-target strategy and standar-dized application of hydroxychloroquine and immunosuppressants in SLE are recommended.

Objective　To analyze and visualize the epidemic changes of schistosomiasis in Wuhan from 2013 to 2022 based on a geographical information system (GIS), providing references for further schistosomiasis control activities. Methods　According to the historical data of the annual reports of schistosomiasis screening and street-level vector map of Wuhan City from 2013 to 2022, a spatial database of epidemic information at the street level was established. The Joinpoint regression model was utilized to analyze the trend of phased changes in blood positivity rate for schistosomiasis. ArcMap 10.8 was employed for the spatial visualization of the positive rate of serological tests for schistosomiasis among the screened population in the endemic areas of Wuhan over the past decade, as well as conducting hot spot analysis (Getis-Ord Gi*) to explore the spatial clustering relationship and spatiotemporal trends. Heatmaps were generated to reflect the changes in the positive rate of blood tests for schistosomiasis over a decade in various streets, and the areas were classified by the ward’s method of hierarchical clustering using the sum of squared deviations. Results　Over the past decade, the overall annual positive rate of schistosomiasis screening in Wuhan declined from 2.23% in 2013 to 0.47% in 2022, showing a general downward trend. The Joinpoint regression model analysis of the blood positive rate indicated the presence of one connection point in 2015; from 2013 to 2015, the annual percent change (APC) of the positive rate was 2.17%, showing an upward trend (P>0.05); from 2015 to 2022, the APC was -23.34%, indicating a downward trend (P<0.05). The map of positive street-level schistosomiasis screening rates for 2013-2022 shows that the positive rate count on the streets of Caidian District and Hannan District in southwestern Wuhan and Huashan Street on the east side, had a significant decrease over the ten years, while the rate in the streets under the jurisdiction of Dongxihu District in the west showed an increase. The hot spot analysis graph revealed that hot spots of the positive rate in Wuhan shifted from the southwest to the west beginning in 2018. The heatmap indicated the largest disparity in trend changes, with the most noteworthy decline in streets under Caidian District and an increasing trend in the streets under Dongxihu District. Conclusions　The overall epidemic situation of schistosomiasis in Wuhan is on a downtrend, although the positive rate of blood tests has increased in some areas. This has been attributed to a reduction in the total number of people participating in the blood tests and the slow decrease of antibodies in certain patients who were repeatedly sampled for testing. It is important to further strengthen the construction of monitoring capabilities, improve the sensitivity of monitoring systems, identify potential risks promptly, and handle them properly.

Objective To evaluate and integrate the facilitators and barriers to adherence to diet or exercise interventions in patients with overweight or obesity.Methods PubMed,Web of Science,Embase,CINAHL,Cochrane Library,China National Knowledge Infrastructure,Wanfang,and VIP Chinese Biomedical Literature Database were searched by computer from the establishment of the database to October 14,2023.The 2016 edition of the Joanna Briggs Institute(JBI)evidence-based health care center qualitative research evaluation criteria was used to evaluate and integrate the included literature.Results A total of 19 studies were included,and 38 outcomes were distilled into 12 categories,and the results were consolidated into facilitators(disease threat perception,self-body perception,self-adjustment,sense of responsibility,social support)and barriers to intervention adherence(poor treatment benefit,low self-efficacy,lack of knowledge,competitive priorities,extemal environmental constraints,economic conditions,poor intervention design).Conclusion There are many facilitators and barriers of diet or exercise intervention perceived by patients.It is suggested that follow-up intervention research should be used as a reference to improve the treatment compliance of patients.
