Objective To analyze the association between lifestyle and the risk of type 2 diabetes(T2D)among adult residents.Methods The data was sourced from the Shanghai Suburban Adult Cohort and Biobank.A total of 42 096 adult residents who had not developed T2D were recruited from four districts of Shanghai(Songjiang,Jiading,Minhang,and Xuhui)between 2016 and 2019.The follow-up ended on Feb 28,2023.A structured questionnaire was used to collect information on six lifestyle-related items,including smoking,alcohol consumption,BMI,waist circumference(WC),physical activity,and diet.The unhealthy lifestyle scores(UHLS)were calculated by counting the number of all the unhealthy lifestyle items,with a range of 0-6.New-onset T2D events diagnosed by physicians were obtained through the medical information system.Cox proportional hazards regression model and restricted cubic spline model were utilized to evaluate the association between unhealthy lifestyles and the risk of T2D incidence.Results About 28.1%of the participants led 4-6 unhealthy lifestyles.A total of 1 752 new T2D cases were identified during 218 513.4 person-years of follow-up.Analysis of single unhealthy lifestyle showed that abnormal WC(HR=1.5,95%CI:1.4-1.7)and abnormal BMI(HR=1.3,95%CI:1.2-1.5)were associated with an increased risk of T2D.Compared with individuals with a UHLS of 0-1,those with a UHLS of 3 and 4-6 had 30%(95%CI:1.1-1.6)and 50%(95%CI:1.2-1.8)higher risks of T2D,respectively.Each additional unhealthy lifestyle was associated with a 10%increase in T2D incidence risk(HR=1.1,95%CI:1.1-1.2).Conclusion The risk of T2D in adult residents increases with the cumulative number of unhealthy lifestyles.Adult residents with abnormal WC or BMI,or have three or more unhealthy lifestyles accumulated,will increase the risk of new-onset T2D.

Purpose To explore the relationship between the proportion of HER2 low expression and clinicopatho-logical characteristics of gastric adenocarcinoma patients.Methods Clinical data from 3 779 gastric adenocarcinoma patients who underwent radical resection were collected.HER2 expression was categorized using immunohistochemistry combined with FISH,and the clinicopathological characteristics and prognosis of HER2 low expression gastric adeno-carcinoma patients were analyzed.Results Among the 3 779 gastric adenocarcinoma cases,1 251 cases(33.10％)showed HER2 low expression.Compared with HER2 negative expression,HER2 low expression patients were more likely to be older males,present with well-differentiated Lauren's intestinal-type adenocarcinoma,and have less nerve invasion.Furthermore,compared to HER2 negative expression,they showed higher Ki67 proliferation index and more advanced clinical stage.Meanwhile,compared with patients with HER2 over expression,those with low HER2 expres-sion were more likely to be younger females,present with well-differentiated Lauren's diffuse-type adenocarcinoma,and have more nerve invasion.Furthermore,compared to HER2 over expression,they showed lower Ki67 proliferation index and more advanced clinical stage.There was no significant difference in prognosis between HER2 low expression,HER2 negative,and HER2 over expression groups.Conclusion HER2 low expression have a relatively large propor-tion in gastric adenocarcinoma patients,and HER2-targeted antibody-drug conjugates may provide an effective treatment option for these patients with HER2 low expression.

Objective To investigate the risk factors for acute respiratory failure in immunocompromised patients with Pneumocystis jirovecii pneumonia(PJP).Methods Clinical data of 123 immunocompromised patients complicated with PJP hospitalized at Mengchao Hepatobiliary Hospital of Fujian Medical University from January 2021 to December 2023 were retrospectively collected and analyzed.SPSS 22.0 statistical software package was used to perform multivariate binary logistic regression analysis to identify risk factors for acute respiratory failure in PJP patients.Results Among the 123 PJP patients,77 were HIV-positive,and 46 were HIV-negative.HIV-negative PJP patients were more likely to have comorbidities such as hypertension(P＜0.001),diabetes mellitus(P＜0.001),coronary heart disease(P=0.034),chronic kidney disease(P＜0.001),chronic liver disease(P=0.019),chronic lung disease(P=0.011),and malignant tumor(P＜0.001).They were also more prone to respiratory failure(P＜0.001)and ICU admission(P＜0.001).The HIV-positive patients had significantly lower CD4+T lymphocyte counts and albumin levels(P＜0.001).Forty patients developed acute respiratory failure,and six patients died.Multivariate analysis showed that high neutrophil-to-lymphocyte ratio(NLR)(P=0.031),non-HIV infection(P=0.002),and concomitant infections with other pathogens(P＜0.001)were independent risk factors for incidence of respiratory failure.ROC curve analysis revealed that the area under the curve(AUC)was 0.686(0.584,0.789)for non-HIV infection,0.731(0.637,0.826)for concomitant infections with other pathogens,0.648(0.546,0.750)for NLR.The predicted probability was 0.845(0.778,0.912).Conclusions Non-HIV infection,high NLR,and concomitant infections with other pathogens are independent risk factors for incidence of respiratory failure in PJP patients.The panel combining these factors provides a higher predictive value for respiratory failure.Timely assessment of patient condition and early treatment are vital for better outcomes.

To investigate the role of the DPP4-nestin axis in liver fibrosis induced by alveolar cyst infection,a murine model was established using C57BL/6 mice via hepatic portal vein injection.Liver histopathological changes were assessed using HE staining,while immunohistochemistry and immunofluorescence were employed to evaluate the expression levels of nestin and DPP4 in infected mouse livers.In vitro,J S1 cell line was stimulated with recombinant DPP4 protein to es-tablish a cellular model,and qPCR,Western blot,and shRNA lentivirus interference techniques were utilized to examine the involvement of the DPP4-nestin axis in hepatic stellate cell activation.The findings demonstrated that compared to the Sham group,liver tissue structure disruption and collagen deposition were evident along with significantly increased expressions of nestin and DPP4(P＜0.050 0),which colocalized with nesin and α-SMA.Furthermore,stimulation with recombi-nant DPP4 protein significantly enhanced JS1 cell activation(P＜0.050 0)as well as upregulated nestin expression(P＜0.050 0)when compared to control group cells.Notably,shRNA lentivirus-mediated inhibition of nestin expression effectively suppressed the activating effects exerted by re-combinant DPP4 protein on JS1 cells(P＜0.050 0).Collectively,these results highlight the crucial regulatory role played by the DPP4-nestin axis in hepatic stellate cell activation triggered by alveo-lar infection;thus,targeting this axis may represent a novel therapeutic strategy for treating alveo-lar infection-induced liver fibrosis.

Purpose: Diagnosing sarcopenia necessitates the measurement of skeletal muscle mass. However, guidelines lack a standardized imaging modality with thresholds validated among Asians. This systematic review compared ultrasonography, computed tomography (CT), magnetic resonance imaging (MRI), and bioelectrical impedance analysis (BIA)/body composition monitoring in the detection of sarcopenia within Asian populations. Methods: PubMed and Embase were systematically searched for studies analyzing ultrasonography, CT, MRI, and BIA in diagnosing sarcopenia among Asians. Study quality was assessed using the Newcastle-Ottawa scale. Results: Pooled findings from 21,598 patients across 25 studies were examined. In receiver operating characteristic analysis, ultrasound displayed a pooled mean area under the curve (AUC) of 0.767 (95% confidence interval [CI], 0.709–0.806), with mean sensitivity of 81.1% (95% CI, 0.744–0.846) and specificity of 73.1% (95% CI, 0.648–0.774), for detecting sarcopenia in Asian populations. CT exhibited an AUC of 0.720 (sensitivity, 54.0%; specificity, 92.0%). MRI demonstrated an AUC of 0.839 (sensitivity, 67.0%; specificity, 66.0%). BIA displayed an AUC of 0.905 (95% CI, 0.842–0.968), 80.7% sensitivity (95% CI, 0.129–0.679), and 82.4% specificity (95% CI, 0.191–0.633). Conclusion Various modalities aid in diagnosing sarcopenia, and selection should be individualized. Although only BIA and dual-energy x-ray absorptiometry are recommended by the Asian Working Group for Sarcopenia and the European Working Group on Sarcopenia in Older People, ultrasound imaging may hold diagnostic value for sarcopenia in the Asian population. In certain groups, diagnostic use of CT and MRI is warranted. Future research can standardize and validate modality-specific thresholds and protocols within Asian populations.
