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.

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 investigate the incidence of hypertension and its influencing factors in community-dwellers at risk for high blood pressure in Minhang District of Shanghai， and to provide scientific evidence for the community management. MethodsA retrospective cohort study was conducted using the electronic health records of community-dwellers at risk for high blood pressure in Minhang District， Shanghai from January 1， 2011 to December 31， 2017. The study end-point was the occurrence of hypertension，and the followup was finished in December 2021. A total of 17 265 community-dwellers at risk for high blood pressure were enrolled in our study. Log-rank test and Cox regression analysis were used to determine the influencing factors. ResultsAfter 6.04 years of follow-up， the hypertension incidence among community-dwellers at risk for high blood pressure in Minhang District of Shanghai was 25.5%. Family history of hypertension （HR=1.250， 95%CI： 1.168‒1.338）， family history of stroke （HR=1.295， 95%CI： 1.080‒1.553）， history of diabetes （HR=1.203， 95%CI： 1.076‒1.345）， daily smoking （HR=1.187， 95%CI： 1.087‒1.296）， overweight （HR=1.393， 95%CI：1.308‒1.484）， obesity（HR=1.903， 95%CI： 1.719‒2.106）， high values of normal blood pressure （HR=1.275， 95%CI： 1.195‒1.359） and advanced age （HR=1.033， 95%CI： 1.030‒1.036） were all risk factors. Emaciation （HR=0.649， 95%CI： 0.500‒0.840） was a protective factors. ConclusionBlood pressure monitoring should be strengthened for people elderly， with family history of hypertension， family history of stroke， diabetes or high values of normal blood pressure， so as to diagnose hypertension early. Timely intervention measures should be taken for community-dwellers with unhealthy lifestyles such as smoking， overweight and obesity.

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.

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.

ObjectiveTo determine the complications of hypertension among local residents in Minhang district of Shanghai， and provide scientific evidence for key preventive intervention. MethodsWe retrieved the data from the electronic health records， in which hypertensive patients were included for community-based management， in Minhang district of Shanghai from January 1st， 2014 to December 31st， 2018. A total of 38 599 hypertensive patients who had not had hypertension related clinical symptom when included in the electronic health records were enrolled in our study. Chi-square test and Cochran-Mantel-Haenszel test were used to determine the complications of hypertension. ResultsThe incidence proportion of complications was 10.77%， of which cerebrovascular damage was the highest （7.44%）， followed by cardiac damage （3.55%） and peripheral vascular damage （0.81%）. The incidence proportions in patients aged 18‒59， 60‒69， 70 and above were 5.53%， 9.61% and 16.19%， respectively. There was significant difference in the incidence proportions of complications among age groups （χ²=668.670， P<0.05）. Cochran-Mantel-Haenszel test showed that in the hypertensive patients aged 60‒69， the incidence proportion of complications in females was lower than that in males （χ²=5.937， P<0.05）. However， in those aged above 70， the incidence proportion of complications in females was higher than that in males （χ²=11.619， P<0.05）. ConclusionIn patients with hypertension， the incidence proportions of cardiovascular and cerebrovascular diseases remains relatively high in Minhang district of Shanghai. Additionally， both age and gender have influence on the incidence of complications.

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.

Patients with cancer are at increased risk of severe infections. From a cohort including 3060 patients with confirmed COVID-19, 109 (3.4%) cancer patients were included in this study. Among them, 23 (21.1%) patients died in the hospital. Cancer patients, especially those with hematological malignancies (41.6%), urinary carcinoma (35.7%), malignancies of the digestive system (33.3%), gynecological malignancies (20%), and lung cancer (14.3%), had a much higher mortality than patients without cancer. A total of 19 (17.4%) cancer patients were infected in the hospital. The clinical characteristics of deceased cancer patients were compared with those of recovered cancer patients. Multivariate Cox regression analysis indicated that a Nutritional Risk Screening (NRS2002) score ⩾ 3 (adjusted hazard ratio (HR) 11.00; 95% confidence interval (CI) 4.60-26.32; P < 0.001), high-risk type (adjusted HR 18.81; 95% CI 4.21-83.93; P < 0.001), tumor stage IV (adjusted HR 4.26; 95% CI 2.34-7.75; P < 0.001), and recent adjuvant therapy (< 1 month) (adjusted HR 3.16; 95% CI 1.75-5.70; P < 0.01) were independent risk factors for in-hospital death after adjusting for age, comorbidities, D-dimer, and lymphocyte count. In conclusion, cancer patients showed a higher risk of COVID-19 infection with a poorer prognosis than patients without cancer. Cancer patients with high-risk tumor, NRS2002 score ⩾ 3, advanced tumor stage, and recent adjuvant therapy (< 1 month) may have high risk of mortality.

Breast cancer brain metastases (BCBMs) are one of the most difficult malignancies to treat due to the intracranial location and multifocal growth. Chemotherapy and molecular targeted therapy are extremely ineffective for BCBMs due to the inept brain accumulation because of the formidable blood‒brain barrier (BBB). Accumulation studies prove that low density lipoprotein receptor-related protein 1 (LRP1) is promising target for BBB transcytosis. However, as the primary clearance receptor for amyloid beta and tissue plasminogen activator, LRP1 at abluminal side of BBB can clear LRP1-targeting therapeutics. Matrix metalloproteinase-1 (MMP1) is highly enriched in metastatic niche to promote growth of BCBMs. Herein, it is reported that nanoparticles (NPs-K-s-A) tethered with MMP1-sensitive fusion peptide containing HER2-targeting K and LRP1-targeting angiopep-2 (A), can surmount the BBB and escape LRP1-mediated clearance in metastatic niche. NPs-K-s-A revealed infinitely superior brain accumulation to angiopep-2-decorated NPs-A in BCBMs bearing mice, while comparable brain accumulation in normal mice. The delivered doxorubicin and lapatinib synergistically inhibit BCBMs growth and prolongs survival of mice bearing BCBMs. Due to the efficient BBB penetration, special and remarkable clearance escape, and facilitated therapeutic outcome, the fusion peptide-based drug delivery strategy may serve as a potential approach for clinical management of BCBMs.

Objective:To understand the characteristics of hepatitis B cases reported through the National Notifiable Disease Reported System (NNDRS) of China in 2019, analyze the quality of hepatitis B reporting.Methods:The survey forms and reporting cards of hepatitis B cases in 200 surveillance points in China in 2019 were collected from NNDRS, the completeness rate of the reporting card was calculated, and the reported hepatitis B cases were verified based on the diagnostic criteria (WS 299-2008). The clinical types of the cases after verification were compared with the reported ones, the consistency was evaluated with Kappa test. The reasons for the inconsistent clinical types of the cases were analyzed.Results:In 2019, a total of 64 686 hepatitis B cases were reported through NNDRS. Acute, chronic and unclassified hepatitis B cases accounted for 5.8%, 92.4% and 1.8%, respectively. The average age of reported cases was 47 (47±15) years, and males accounted for 64.4%. The average level of alanine aminotransferase was 214.2 (214.2±1 253.4) U/L. The reported cases mainly worked in agriculture, forestry, animal husbandry, fishery, and water conservancy (50.6%, 32 722). The proportions of cases reported from the eastern, western and central regions were 42.5% (27 501),22.1% (14 315) and 35.4% (22 870), respectively. The consistent rate of the clinical types between the reported cases and the verified cases was 58.8%, with a Kappa value of 0.15. For the 39 271 cases confirmed as acute and chronic hepatitis B cases in the reporting cards, the consistent rate of the clinical types between the reported cases and the verified cases was 96.9%, with a Kappa value of 0.73. In 94.5% (24 267/25 681) of the cases with inconsistent clinical types, the reporting card information were incomplete.Conclusion:The diagnosis of hepatitis B has been improved in the hepatitis B surveillance in China, but it is necessary to improve the completeness of the reporting cards of hepatitis B cases to NNDRS.
