Objective To explore the impact of seasonal and temperature variations on fasting blood glucose(FPG)in patients with type 2 diabetes(T2DM).Methods A retrospective analysis was conducted on clinical data of 31 994 T2DM patients managed by community health service center in Minhang District,Shanghai,from January 1,2020 to October 31,2023.The effect of seasonal and temperature variations on FPG levels and blood glucose control was investigated in T2DM patients.Results A total of 72 334 FPG tests were conducted in 31 994 T2DM patients,with an average of 2.26 tests per person.The number of tests conducted in spring,summer,autumn and winter were 15 558,34 018,21 929 and 829,respectively.The FPG levels of T2DM patients were lower in summer and autumn compared to those of winter and spring(P<0.05),while the FPG control rates were higher in summer and autumn compared to those of winter and spring(Bonferroni-corrected,P<0.008).There were no significant differences in FPG levels and blood glucose control rates between spring and winter,or between summer and autumn.The results of the multilevel mixed-effect Logistic model analysis with FPG control status as the dependent variable revealed that the risk of uncontrolled FPG in T2DM patients during winter and spring was 47%(aOR=1.465,95%CI:1.156-1.855)and 51%(aOR=1.510,95%CI:1.384-1.645),respectively,which was higher than that of autumn.The levels of FPG and the incidence of FPG abnormalities reached peak in February and reached the trough in September.Both the FPG levels and the incidence of FPG abnormal exhibited a trend of increasing with the decrease of temperature,and with a lag effect observed.Spearman rank correlation test indicated that there was a negative correlation between FPG levels and incidence of abnormal FPG and the monthly average daily temperature one month lagged(rs=-0.951,P＜0.001 and rs=-0.944,P＜0.001).Conclusion FPG levels of T2DM patients exhibit a pronounced seasonal pattern of elevation during winter and spring,accompanied by a reduction in blood glucose control rates.FPG levels and the prevalence of abnormal FPG exhibit a negative correlation with the monthly average daily temperature,and there is a lag effect.

Objective: To examine the relationship between self-management behaviors and time perspective among patients with comorbid diabetes, so as to provide the evidence for improving self-management behaviors among patients with comorbid diabetes. Methods: The patients with comorbid diabetes who were registered in the chronic disease health management system of Minhang District, Shanghai Municipality in 2021, followed up regularly, and lived in Meilong Town were recruited. Demographic information and family history of diabetes were collected through questionnaire surveys. Time perspective and self-management behaviors were assessed using the Zimbardo Time Perspective Inventory and Diabetes Self-Management Behavior Scale, respectively. The relationship between self-management behaviors and time perspective was analyzed using a multivariable ordinal logistic regression model. Results: A total of 907 patients with comorbid diabetes were enrolled, including 472 males (52.04%) and 435 females (47.96%). There were 652 cases aged 65 years and above, accounting for 71.89%. In terms of the types of time perspective, 280 patients were future-oriented (30.87%), 236 were balanced (26.02%), 162 were sensation-seeking (17.86%), 123 were fatalistic (13.56%), and 106 were negative (11.69%). In terms of the self-management behaviors, 46 patients were good (5.07%), 643 were moderate (70.89%), and 218 were poor (24.04%). Multivariable ordinal logistic regression analysis showed that after adjusting for age, gender, educational level, marital status, occupation status, monthly income, and family history of diabetes, the patients with comorbid diabetes who had a future-oriented time perspective had better self-management behaviors (OR=1.874, 95%CI: 1.204-2.915). Conclusion The self-management behaviors among patients with comorbid diabetes are moderate to poor, and patients with a future-oriented time perspective can better engage in self-management behaviors.

Objective To describe the clinical features of patients with primary sclerosing cholangitis(PSC)in China based on a nationwide multicenter patient cohort,and to investigate the risk factors for prognosis.Methods A retrospective cohort study was conducted among the patients with a confirmed diagnosis of PSC based on the electronic medical record system of seven grade A tertiary hospitals across the country,and related data were extracted.The Mann-Whitney U test was used for comparison of continuous data between groups,and the chi-square test was used for comparison of categorical data between groups.The Kaplan-Meier method was used to estimate liver transplant-free survival,and the log-rank test was used for comparison of survival rate between PSC patients with different features.The Cox regression model was used to identify independent risk factors for the prognosis of PSC patients and the interactions between key factors.Results A total of 107 patients were enrolled,among whom 55.6%(55/99)had large-duct PSC and 29.0%(31/107)had comorbidity with inflammatory bowel disease(IBD).The positivity rate of anti-neutrophil cytoplasmic antibody(ANCA)was 32.9%(24/73),and 50.0%(40/80)of the patients had an increase in IgG/IgM.The median symptom-to-diagnosis interval was 1 year(<1-4.0),and 38.3%(41/107)of the patients had progressed to decompensated cirrhosis at the time of diagnosis.The median liver transplant-free survival time was 114 months(95%confidence interval[CI]:62-166),with a 5-year survival rate of 65.7%.The multivariate analysis showed that an increase in total bile acid(TBA)(hazard ratio[HR]=1.006,95%CI:1.002-1.010,P=0.001)and a prolonged symptom-to-diagnosis interval(HR=1.252,95%CI:1.059-1.480,P=0.009)were independent risk factors for prognosis.The interaction analysis showed that compared with the female patients with TBA<50 μmol/L,both male and female patients with TBA≥50 μmol/L had a significant increase in the risk of liver transplantation or death(male:HR=16.563,95%CI:2.103-130.449,P<0.001;female:HR=17.009,95%CI:2.113-136.934,P<0.001),and compared with the patients with an age of<45 years and a TBA level of<50 μmol/L,the patients with an age of≥45 years and a TBA level of≥50 μmol/L had a significant increase in the risk of liver transplantation or death(HR=10.729,95%CI:1.325-86.859,P=0.026).Compared with the female patients with an symptom-to-diagnosis interval of≤2 years,the male patients with a symptom-to-diagnosis interval of>2 years had an increased risk of liver transplantation or death(HR=4.825,95%CI:1.725-13.644,P=0.003),and compared with the patients with an age of<45 years and a symptom-to-diagnosis interval of≤2 years,the patients with an age of<45 years and a symptom-to-diagnosis interval of>2 years had an increased risk of liver transplantation or death(HR=4.983,95%CI:1.366-18.173,P=0.015).Conclusion Compared with the reports from Western countries,large-duct PSC is also the main type of PSC in China,but with a relatively low proportion,and there is also a relatively low proportion of patients with IBD or positive ANCA.An increase in TBA and a prolonged symptom-to-diagnosis interval are independent risk factors for prognosis,with significant interactions with age and sex.This suggests that early screening and intervention should be enhanced to improve prognosis.

The aim of this study is to establish a simple and accurate method for vaccine immune e-valuation of porcine pseudorabies virus.In this research,PRV-gD recombinant protein was ex-pressed from mammalian cell HEK-293F as coating antigen,and then the reaction conditions of gD-iELISA were optimized according to checkerboard titration method.The gD-iELISA was used to detect the antibody levels of 211 clinical pig serum samples and the consistency with the neu-tralizing antibody levels wasanalyzed.The results showed that the antigen coating concentration was 0.90 mg/L;the serum to be detected was diluted 1∶100 and incubated at 37 ℃ for 30 min;goat anti-pig IgG-HRP antibody was diluted 1∶55 000 and incubated at 37 ℃ for 30 min;TMB sub-strate was developed at 37 ℃ for 20 min.The method could detect 1∶6 400 diluted PRV positive serum.The results of CSFV,PRRSV,PCV-2,PEDV and FMDV positive sera were all negative by gD-iELISA,and there was no cross-reaction between the method and the above positive sera.The coincidence rate of gD-iELISA and commercial kits was 95.26％,and the intra-and inter-batch co-efficients of variation were both less than 10％.Correlation analysis showed that the correlation coefficient(r)between gD antibody level and neutralizing antibody level was significantly greater than that of gB antibody level,and the gD antibody level had a good linear relationship with the neutralizing antibody level.The results indicated that gD-iELISA was more suitable for vaccine im-mune evaluation of PRV than gB-iELISA.Therefore,the method will have a good prospect of ap-plication in the immunization control of the PRV.

The BTB (broad-complex, tramtrack, and bric-à-brac) domain is a highly conserved protein interaction motif in eukaryotes. They are widely involved in transcriptional regulation, protein degradation and other processes. Recently, an increasing number of studies have shown that these genes play important roles in plant growth and development, biotic and abiotic stress processes. Here, we summarize the advances of these proteins ubiquitination-mediated development and abiotic stress responses in plants based on the protein structure, which may facilitate the study of this type of gene in plants.

ObjectiveTo explore the cumulative incidence of diabetes mellitus and its influencing factors among the diabetes mellitus high-risk groups in Minhang District of Shanghai, and to provide a basis for the development of community-based diabetes mellitus early prevention and treatment strategies in Shanghai. MethodsThe data of this study were collected from the screening project of diabetes mellitus high-risk groups in Minhang District of Shanghai, which was carried out from 2016‒2017. A total of 12 278 people were screened, of which 10 442 were at high risk based on the results of blood glucose diagnosis except those with diabetes. People diagnosed with abnormal fasting blood glucose, impaired fasting blood glucose and abnormal glucose tolerance were classified into the abnormal blood glucose group, and those with normal fasting blood glucose were classified into the normal blood glucose group. In 2023, the cumulative incidence of diabetes mellitus in the 2 groups was followed up, furthermore, the influencing factors of diabetes mellitus were analyzed. ResultsA total of 8 774 cases within the high-risk groups were followed up in 2023, of which 808 cases progressed to diabetes. Of the 8 774 cases, the cumulative incidence of diabetes mellitus in the abnormal blood glucose group (n=2 163) was 16.37% (354/2 163), and that in the normal blood glucose group (n=6 611) was 6.87% (454/6 611), and the difference in cumulative incidence of diabetes mellitus between the 2 groups was statistically significant (χ²=175.88, P<0.001). A history of impaired glucose regulation (OR=2.828, 95%CI: 2.177‒3.675), family history of type 2 diabetes (OR=1.294, 95%CI: 1.047‒1.600), hypertension (OR=1.268, 95%CI: 1.083‒1.485), dyslipidemia (OR=1.205, 95%CI: 1.003‒1.448), overweight/obesity (OR=1.526, 95%CI: 1.300‒1.792) were positively correlated with the cumulative incidence of type 2 diabetes, while female gender (OR=0.785, 95%CI: 0.675‒0.914) and sedentary lifestyle (OR=0.506, 95%CI: 0.374‒0.685) were negatively correlated with the cumulative incidence of type 2 diabetes. ConclusionBlood glucose monitoring should be strengthened in diabetes mellitus high-risk groups with an impaired glucose regulation history, a family history of type 2 diabetes, hypertension, and dyslipidemia, so as to achieve early detection of diabetes. Timely intervention measures should be taken for high-risk population with unhealthy lifestyle or overweight/obesity.

Objective:To understand the clinical characteristics of hospitalized patients with liver cirrhosis, so as to provide theoretical basis for disease diagnosis and treatment, formulation of intervention measures, and improve the level of disease diagnosis and treatment.Methods:Hospitalized patients who were initially diagnosed with liver cirrhosis at Peking University First Hospital from August 2017 to December 2018 were selected retrospectively as the research objects. Liver cirrhosis demographic data, etiology, severity classification, incidence of complications, diagnosis and prognosis were recorded. Statistical analysis was performed using SPSS software.Results:Among all liver cirrhosis cases, there were 291 males and 209 females, with a male-to-female ratio of 1.4:1 and an age of 59.5±12.9 years as at August 2017 to December 2018. HBV infection, alcoholic liver disease, and autoimmune liver diseases were the most common etiology of liver cirrhosis. HBV infection alone, HBV infection combined with other factors, alcoholic liver disease alone, alcoholic liver disease combined with other factors, autoimmune liver disease alone, and autoimmune liver disease combined with other factors were presented in 163 (32.6%), 57 (11.4%), 47 (9.4%), 63 (12.6%), 85 (17.0%), and 22 (4.4.0%) cases, respectively. Ascites (221 cases, 44.2%), followed by esophagogastric varices (214 cases, 42.8%), and other including hypersplenism (137 cases), liver cancer (126 cases), upper digestive system tract hemorrhage (66 cases), hepatic encephalopathy (40 cases), infection (37 cases), portal vein thrombosis (23 cases), hepatorenal syndrome (20 cases) were the most common complications. The most common site of infection was the abdominal cavity (20 cases), accounting for 54.1%; followed by respiratory tract infection (8 cases), accounting for 21.6% in patients with liver cirrhosis with concurrent infection. Among them, there were 32 cases of bacterial infection alone, one case of bacterial infection combined with fungal infection, one case of bacterial infection combined with viral infection, and three cases of unknown pathogens. There were 69 cases in Child Pugh grade C, and the average hospitalization times were 12.6 days in terms of prognosis. There were total seven cases of death, of which five cases were due to upper gastrointestinal hemorrhage and two due to hepatic encephalopathy.Conclusion:HBV infection, ascites, and upper gastrointestinal bleeding were the most common etiologies, complications, and causes of death in patients with liver cirrhosis at our hospital.
