BACKGROUND: Research has indicated that the disease burden of alopecia areata (AA) in China exceeds the global average. Therefore, accurate and updated epidemiological information is crucial for policymakers. In this study, we aimed to comprehensively assess the disease burden of AA in China. METHODS: The following four key indicators were utilized: the prevalence of cases; disability-adjusted life-years (DALYs); the age-standardized prevalence rate (ASPR); and the age-standardized DALY rate (ASDR) of AA according to the Global Burden of Disease (GBD) study 2021. We analyzed the epidemiological burden of AA in China during 2021, examined changes between 1990 and 2021, and performed a Bayesian age-period-cohort analysis to predict trends over the course of the next decade (2022-2030). Additionally, a Gaussian process regression model was applied to estimate the relationship between the gross domestic product (GDP) and the ASPR and ASDR of AA at the provincial level between 1992 and 2021. RESULTS: In 2021, the estimated number of patients with AA in China was approximately 3.49 million (95% uncertainty interval [UI], 3.37-3.62 million); of these patients, 1.20 million (95% UI, 1.16-1.25 million) were male and 2.29 million (95% UI, 2.20-2.37 million) were female. This large number of patients with AA resulted in a total of 114,431.25 DALYs (95% UI, 74,780.27-160,318.96 DALYs). Additionally, the ASPR and ASDR were 224.61 per 100,000 population (95% UI, 216.73-232.65 per 100,000 population) and 7.41 per 100,000 population (95% UI, 4.85-10.44 per 100,000 population), respectively; both of these rates were higher than the global averages. The most affected demographic groups were young and female individuals 25-39 years of age. Slight regional disparities were observed, with the northern and central regions of China bearing comparatively higher burdens. Between 1990 and 2021, the health loss and disease burden caused by AA in China remained relatively stable. The ASPR and ASDR of AA increased with the GDP when the annual GDP was less than 2 trillion Chinese yuan; however, a downward trend was observed as the GDP surpassed 2 trillion Chinese yuan. A slight upward trend in the disease burden of AA in China is predicted to occur over the next decade. CONCLUSIONS AA continues to be a public health concern in China that shows no signs of declining. Targeted efforts for young individuals and females are necessary because they experience a disproportionately high burden of AA.

The high incidence of bleeding after peripherally inserted central catheter (PICC) catheterization increases the risk of puncture site infection and unplanned extubation. Hemostatic dressings should be used in the early stages of catheterization to reduce blood infiltration. However, new hemostatic dressings have various types and advantages, which makes them difficult to choose dressings for medical staff. This paper introduces the types and hemostatic characteristics of novel functional hemostatic dressings, reviews the hemostatic mechanism and hemostatic effect of chitosan, cyanoacrylate gum, alginate, gelatin sponge and oxycellulose dressings in PICC puncture respectively, and prospects the development of new functional hemostatic dressings. It is expected that future hemostatic dressings will move towards multifunctionality and compositeness.

Objective:To investigate the association between hyperuricemia and the risk for stroke occurrence, as well as the mediating effect of hypertension on this association.Methods:In this study, the China Chronic Diseases and Nutrition Surveillance system in 2015 was used as baseline data. We identified hospital admissions for stroke using the electronic homepage of inpatient medical records from 2013-2020, and death data were obtained from the 2015-2020 National Mortality Surveillance System. A retrospective cohort was established after matching and linking the database. The Cox proportional hazard regression model was used to analyze the relationship between hyperuricemia and the risk of stroke and its subtypes. Restricted cubic spline analysis was conducted to examine the dose-response relationship between serum uric acid levels and the risk for stroke. Mediation analysis was performed to investigate the mediating effect of hypertension on the association between hyperuricemia and the risk for stroke and its subtypes. Subgroup analyses were conducted based on gender and age groups.Results:A total of 124 352 study subjects were included, with an accumulative follow-up time of 612 911.36 person-years. During the follow-up period, 4 638 cases of stroke were found, including 3 919 cases of ischemic stroke and 689 cases of hemorrhagic stroke. The incidence density of stroke was 756.72 per 100 000 person-years, 641.37 per 100 000 person-years for ischemic stroke, and 114.60 per 100 000 person-years for hemorrhagic stroke. Multivariable Cox proportional hazards regression models showed that after adjusting for covariates, compared to those without hyperuricemia, individuals with hyperuricemia had a 16% higher risk for stroke [hazard ratio ( HR)=1.16, 95% CI: 1.06-1.27], a 12% higher risk of ischemic stroke ( HR=1.12, 95% CI: 1.01-1.24), and a 39% higher risk of hemorrhagic stroke ( HR=1.39, 95% CI: 1.11-1.75). Mediation analysis showed that hypertension partially mediated the associations between hyperuricemia and the risk for stroke, ischemic stroke, and hemorrhagic stroke, with mediation proportions of 36.07%, 39.98%, and 25.34%, respectively. The mediating effect is pronounced in the male population and individuals below 65. Conclusion:Hyperuricemia is a risk factor for stroke, and hypertension partially mediates the effect of hyperuricemia on stroke.

Objective To explore the guiding value of thromboelastography(TEG)in the formulation of personalized anticoagulation regimen after knee arthroscopy.Methods A total of 50 patients who underwent knee arthroscopy in our hos-pital from April to August 2023 were randomly divided into two groups.Twenty-seven patients with routine anticoagulation were selected as the control group,and 23 patients with personalized anticoagulation were selected as the experimental group.Conventional anticoagulation was a prophylactic dose of low molecular weight heparin calcium(LMWHC)selected according to body weight,once a day to 7 days after surgery.Personalized anticoagulation was performed according to the prophylactic dose of LMWHC until postoperative day 3.On postoperative day 3,LMWHC was changed to aspirin according to the TEG return index(MA>70 mm,α Angle>72°,K value<1 min),and the initial prophylactic dose was 100 mg/d.LMWHC was changed to rivaroxaban when R<5 min,and the prophylactic dose was 10 mg/d until postoperative day 7.Pa-tients with hypocoagulation or subcutaneous ecchymosis stopped the drug first,and if it was further aggravated,component blood transfusion was performed according to the TEG results.The difference of Caprini score in perioperative period,the correlation between TEG and CCT on postoperative day 1,and the accuracy of predicting thrombosis on postoperative day 7 were compared between the two groups using the receiver operating characteristic curve(ROC).Results There was a sig-nificant difference in Caprini score between the two groups at 7 days after operation(P<0.05),suggesting that the adjust-ment of anticoagulant drugs in the experimental group was effective at 3 days after operation.Pearson correlation evaluation showed that there was a strong positive correlation between maximum coagulation intensity(MA)in TEG and platelet(Plt)in CCT at day 1 after surgery(P<0.05).Thrombosis was found in the control group at 7 days after operation,all of which were CMVT and disappeared after therapeutic antithrombotic therapy.MA was included in the ROC curve for model analysis.The area under the ROC curve(AUC)of the control group was 0.819,and the AUC of the experimental group was 0.508.It was found that the control group model had higher accuracy in predicting the formation of CMVT.Conclusion Individu-alized anticoagulation under TEG monitoring can effectively reduce the occurrence of CMVT after knee arthroscopy,which has guiding value for anticoagulation and thrombosis prevention.

Background::Evaluating the impact of digestive system diseases is vital for devising effective prevention strategies. However, comprehensive reports on the burden of digestive system diseases in China are lacking. Our study aimed to provide an overview of the burden and trends of digestive system diseases from 1990 to 2019 in China and its provinces.Methods::This cross-sectional study utilized the Global Disease Burden Study 2019 to estimate the incidence, mortality rate, disability-adjusted life years (DALYs), years of life disability, years of life lost, and changes in the burden of digestive diseases across Chinese provinces from 1990 to 2019. The analysis of disease burden primarily examines the characteristics of sub-disease distribution, time trends, age distribution, and sex distribution. Additionally, we compared provincial age-standardized DALYs for digestive diseases with the expected rates based on the socio-demographic index (SDI).Results::In 2019, there were 499.2 million cases of digestive system diseases in China, resulting in 1,557,310 deaths. Stomach cancer, colon and rectal cancer, and esophageal cancer are the top three diseases associated with mortality and DALY related to digestive system diseases. Meanwhile, cirrhosis and other chronic liver diseases, gastroesophageal reflux disease, and gallbladder and biliary diseases are the top three kinds of diseases with the highest prevalence among digestive system diseases. The risk of gastric cancer sharply increases among men after the age of 40 years, leading to a significant disparity in burden between men and women. As the SDI increased, the DALYs associated with digestive system diseases in China and its provinces showed a downward trend.Conclusion::Our study highlights the inverse correlation between DALYs associated with digestive system diseases and the SDI.

Objective:To investigate the current situation of the fatalism of the disabled elderly in hospital, and to analyze the influencing factors, so as to provide a basis for the later development of targeted intervention programs.Methods:This was a cross-sectional survey study. From December 2 to 29, 2023, the convenience sampling method was used to investigate the disabled elderly hospitalized in 7 tertiary general hospitals in Sichuan Province by the general information questionnaire, the Activity of Daily Living scale and the Fatalism Scale. And its influencing factors were conducted by the multivariate linear regression.Results:A total of 280 questionnaires were distributed in this survey, and 269 questionnaires were effectively recovered, with an effective recovery rate of 96.07%(269/280). There were 136 males and 133 females, aged 60-69 years old with 61 cases, 70-79 years old with 103 cases, ≥80 years old with 105 cases. The score of the fatalism in hospitalized disabled elderly was (48.87 ± 10.02) points, of which the pre-determined dimension score was (18.73 ± 4.17) points, the luck dimension score was (12.75 ± 3.42) points, and the pessimistic dimension score was (17.39 ± 4.72) points. Multivariate linear regression showed that the frequency of visits to relatives and friends and the level of education were protective factors for the occurrence of fatalism (t=-3.02, -2.81, both P<0.05), and economic pressure was a risk factor for the occurrence of fatalism (t=4.35, P<0.01).Conclusions:The fatalistic view of the disabled elderly in the hospital is at a medium level.Medical staff can start from the influencing factors, formulate relevant intervention measures, and improve the level of the patient's fatalism.

With the increasing aging process, the number of elderly people with cognitive frailty is gradually increasing, which has a profound impact on the clinical outcomes of the elderly. Early identification and precise intervention of cognitive frailty can delay the occurrence of adverse outcomes. This paper reviews the development and research status of cognitive frailty risk prediction models for the elderly in the community, summarizes and compares the characteristics and basic situation of each prediction model, in order to provide references for improving the early identification and intervention of cognitive frailty among the elderly population in the community.

Objective:To explore the current situation of stigma among disabled elderly inpatients and analyze its influencing factors, so as to provide reference for formulating targeted intervention measures.Methods:This study was a cross-sectional survey. In December 2023, convenience sampling was used to select 428 disabled elderly inpatients from 12 ClassⅢ Grade A hospitals in Sichuan Province as research subjects. General Information Questionnaire and Social Impact Scale (SIS) were used to conduct surveys on patients. Multiple linear regression analysis was used to explore the influencing factors of stigma among disabled elderly inpatients.Results:A total of 428 questionnaires were distributed, and 407 valid questionnaires were collected, with a valid response rate of 95.09% (407/428). SIS score of 407 disabled elderly inpatients was (56.55±8.38). Multiple linear regression analysis showed that the number of diseases, educational level, and self-rating economic pressure were the influencing factors of stigma among disabled elderly inpatients ( P<0.05) . Conclusions:The stigma among disabled elderly inpatients is at a moderate level. Medical and nursing staff should establish a comprehensive prevention and management mechanism based on influencing factors.

Objective:To investigate the association between diet, physical activity and cognitive impairment among elderly patients with diabetes mellitus.Methods:This study investigated patients aged 60 years and above with type 2 diabetes in the Department of Endocrinology at Penglai People's Hospital from October 2021 to May 2022.Information on patients' demographics, lifestyle, disease history, daily diet, physical activities, and social network was collected using questionnaires.The Montreal Cognitive Assessment(MoCA)was utilized to evaluate the cognitive status of the participants.A logistic regression model was conducted to identify the associations between diet, physical activity, and cognitive impairment.Results:A total of 1 355 patients aged 60 years and above with type 2 diabetes were included in this study.During the assessment, 565(41.7%)patients were identified as having cognitive impairment.After adjusting for other factors, it was found that alcohol consumption was associated with a higher risk of cognitive impairment( OR: 1.45, 95% CI: 1.04-2.04, P=0.03).Furthermore, patients with diabetes who consumed fruits more than once a day had a higher risk of cognitive impairment( OR: 1.52, 95% CI: 1.20-1.93, P<0.001).On the other hand, the consumption of vegetables was found to be negatively associated with the risk of cognitive impairment( OR: 0.41, 95% CI: 0.24-0.68, P=0.001).Additionally, engaging in physical activities and having a strong social network were found to significantly reduce the risk of cognitive impairment( OR: 0.49, 95% CI: 0.39-0.64, P<0.001; OR: 0.56, 95% CI: 0.43-0.71, P<0.001)respectively. Conclusions:Our findings indicate a significant association between diet, physical activity, and cognitive function in elderly individuals with type 2 diabetes.It is crucial to identify and intervene on risk factors to delay and prevent cognitive impairment.Furthermore, these interventions may also aid diabetes patients in effectively managing their cognition.

To screen and identify the key host proteins interacting with the non-structural protein 15 (Nsp15) of porcine epidemic diarrhea virus (PEDV). The IP/pull-down assay and mass spectrometry were employed to screen and identify the host proteins interacting with Nsp15. The interaction between the host protein and Nsp15 was studied by co-immunoprecipitation and laser scanning confocal microscopy. Finally, Western blotting and RT-qPCR were employed to examine the interaction between SLC25a3 and PEDV. The recombinant eukaryotic expression vector pcDNA3.1(+)-Flag-Nsp15 was successfully constructed, and the host protein SLC25a3 interacting with PEDV Nsp15 was screened out. An interaction existed between SLC25a3 and Nsp15, and SLC25a3 significantly inhibited PEDV replication in a dose-dependent manner. SLC25a3 inhibits PEDV replication. The results of this study provide a basis for deciphering the role and mechanism of SLC25a3 in the host immune response to PEDV infection.
