Objective: To investigate the characteristics and trend of stroke incidence in Yixing City, Jiangsu Province from 2016 to 2023, so as to provide the reference for formulating prevention and control strategies of stroke. Methods: Data of stroke case in Yixing City from 2016 to 2023 were collected from the National Health Information Platform of Yixing City, including sex, age, time of onset, and diagnostic subtypes. Crude incidence was standardized using the data from the 2010 Chinese National Population Census to analyze the characteristics of stroke incidence. The incidence trend of stroke was analyzed by average annual percent change (AAPC). Results: A total of 54 157 stroke cases were reported in Yixing City from 2016 to 2023, with a crude incidence of 629.52/100 000 and a standardized incidence of 299.50/100 000, showing an upward trend (AAPC=9.744% and 5.955%, both P<0.05). The crude and standardized incidence of stroke in males were significantly higher than those in females (695.30/100 000 vs. 565.79/100 000, 328.73/100 000 vs. 270.71/100 000, both P<0.05). Stroke incidence exhibited an age-dependent increase (P<0.05), peaking in the ≥60 years age group (1 820.43/100 000). The crude and standardized incidence of ischemic stroke (555.46/100 000 and 262.26/100 000) were significantly higher than those of hemorrhagic stroke (52.80/100 000 and 28.03/100 000, both P<0.05). From 2016 to 2023, the standardized incidences of stroke in males, females, the 0-<40 years age group, the 40-<60 years age group, the ≥60 years age group, and ischemic stroke all showed an upward trend (AAPC=6.692%, 4.925%, 5.607%, 5.777%, 5.698%, and 8.481%, respectively, all P<0.05). No significant temporal trend was observed for hemorrhagic stroke incidence (P>0.05). Conclusions The incidence of stroke among residents in Yixing City showed an upward trend from 2016 to 2023, with males and elderly individuals being high-risk populations. Ischemic stroke emerged as the predominant subtype, while a concerning trend of increasing stroke incidence among younger adults was observed.

This study aimed to comprehensively examine the association of gallstones, cholecystectomy, and cancer risk. Multivariable logistic regressions were performed to estimate the observational associations of gallstones and cholecystectomy with cancer risk, using data from a nationwide cohort involving 239 799 participants. General and gender-specific two-sample Mendelian randomization (MR) analysis was further conducted to assess the causalities of the observed associations. Observationally, a history of gallstones without cholecystectomy was associated with a high risk of stomach cancer (adjusted odds ratio (aOR)=2.54, 95% confidence interval (CI) 1.50-4.28), liver and bile duct cancer (aOR=2.46, 95% CI 1.17-5.16), kidney cancer (aOR=2.04, 95% CI 1.05-3.94), and bladder cancer (aOR=2.23, 95% CI 1.01-5.13) in the general population, as well as cervical cancer (aOR=1.69, 95% CI 1.12-2.56) in women. Moreover, cholecystectomy was associated with high odds of stomach cancer (aOR=2.41, 95% CI 1.29-4.49), colorectal cancer (aOR=1.83, 95% CI 1.18-2.85), and cancer of liver and bile duct (aOR=2.58, 95% CI 1.11-6.02). MR analysis only supported the causal effect of gallstones on stomach, liver and bile duct, kidney, and bladder cancer. This study added evidence to the causal effect of gallstones on stomach, liver and bile duct, kidney, and bladder cancer, highlighting the importance of cancer screening in individuals with gallstones.

OBJECTIVE To know about the working mode and human resource status of pharmacy intravenous admixture services （PIVAS） in national medical institutions. METHODS Through questionnaire survey， the national PIVAS was invited to fill out questionnaire and statistical analysis was performed on the effective sample data related to PIVAS working mode and human resources in the questionnaire. RESULTS In this study， 761 PIVAS from 722 medical institutions of 29 provinces were involved in the questionnaire survey， with 471 valid questionnaires for working mode and 441 valid questionnaires for human resources survey. In terms of working mode， among 471 PIVAS， 292 PIVAS （62.0%） were in pharmacist-alone mode， and 176 PIVAS （37.4%） were in pharmacist-nurse cooperative mode； there was no significant difference in the types of medical orders received by PIVAS between these two working modes except for the other medical orders （P＞0.05）. In terms of human resource setting， among 441 PIVAS， the average number of total staff of single PIVAS was 24（16，33）， including 11（6，19） pharmacists， 7（2，13） nursing staff， and 3（1，5） workers； there was a statistically significant difference in the number of personnel among three groups （P＜ 0.01）. The per capita income of PIVAS respondents in 2019 was [7.9（4.8，10.7）]×104 yuan， and in 2021 it was [8.8（5.8，11.7）]× 104 yuan， with an increase of 9.0% compared to 2019. The difference between the two groups was statistically significant （P＜ 0.01）. CONCLUSIONS Medical institutions’ PIVAS in China had not fully implemented the pharmacist-alone work model， and some medical institutions had chosen a pharmacist-nurse cooperative mode. It is suggested that relevant departments formulate corresponding qualification requirements and training standards for nursing personnel as soon as possible based on sufficient research on PIVAS’s demand for nursing professionals.

OBJECTIVE To know about the pharmacy intravenous admixture charge and operation balance of pharmacy intravenous admixture services （PIVAS） in national medical institutions. METHODS Using questionnaire survey method， the national PIVAS leaders were invited to fill in the questionnaire， investigation and statistical analysis of the drug dispensing charge standard and the income and expenditure situations of PIVAS nationwide were conducted. RESULTS A total of 761 PIVAS completed the questionnaire， among which 466 PIVAS （61.2%） had already started implementing pharmacy intravenous admixture charge， mainly in tertiary hospitals. The charge standards for chemotherapy drugs and parenteral nutrition solutions were relatively high， while the standards for packaged drugs were the lowest， with differences in charge standards among provinces（P＜0.05）. Among the 25 provinces that reported annual drug preparation fee revenue， Hubei had the highest revenue in both 2019 and 2021. In 2019， the number of PIVAS with a balance of payments was more than that of PIVAS with an imbalance of payments， but the number of PIVAS with an imbalance of payments in 2021 exceeded the number of PIVAS with a balance of payments （P＜0.05）； among them， eight provinces were unbalanced in 2019 and 2021， such as Tianjin， Chongqing， Guizhou， etc. CONCLUSIONS PIVAS charge standards of the surveyed medical institutions in all provinces are not unified. It is suggested to improve the charge standard further， formulate the charge adjustment cycle， and promote a sustainable development of PIVAS.

Objectives:To explore the changes of some peripheral blood cells related to inflammation in patients with non-arteritis central retinal artery occlusion (NA-CRAO).Methods:A retrospective clinical study. From July 2019 to July 2021, a total of 218 patients with NA-CRAO hospitalized (NA-CRAO group) in Department of Ophthalmology, Xi'an People's Hospital (Xi'an Fourth Hospital) and 218 patients with routine physical examination (control group) during the same period were included in the study. There were no significant differences in age ( t=0.60), sex composition ratio ( χ2=0.83) and body mass index ( t=0.77) between the two groups ( P>0.05). 0.2 ml fasting peripheral blood was collected from the subject, and white blood cells (WBC), neutrophils (NEUT), lymphocytes (LYMPH), red blood cells (RBC), RBC distribution width (RDW), platelets (PLT), mean PLT volume (MPV), and large PLT ratio (PLCR) were detected. The NEUT/LYMPH ratio (NLR) and PLT/LYMPH ratio (PLR) were calculated. t test was used to compare measurement data between groups. Multiple logistic regression analysis was performed for blood cells with P <0.05. The receiver operating characteristic curve (ROC curve) was used to calculate the area under the curve (AUC) and 95% confidence interval (95% CI) of each inflammatory indicator, and the optimal cutoff value was determined according to the Jorden index (sensitivity+specificity-1). Results:Compared with control group, WBC, NEUT, NLR, RDW, PLR were increased in NA-CRAO group, while RBC and LYMPH were decreased, with statistical significance ( t=9.68, 12.43, 9.47, 3.64, 5.54, 5.18, 0.46; P<0.001). There was no significant difference in PLT, MPV and PLCR between the two groups ( t=0.32, 1.56, 0.84; P>0.05). Multivariate logistic regression analysis showed that NLR was a possible risk factor for the occurrence of NA-CRAO (odds ratio=2.51, 95% CI 0.780-0.859, P=0.031). ROC curve analysis showed that the AUC predicted by NLR was 0.819, the optimal critical value was 3.05, and the sensitivity and specificity were 59.2% and 92.7%, respectively. Conclusions:In peripheral blood cells of NA-CRAO patients, NEUT is significantly increased and LYMPH is decreased. NLR is a possible risk factor for NA-CRAO.

Background/Aims: Low educational attainment is a well-established risk factor for nonalcoholic fatty liver disease (NAFLD) in developed areas. However, the association between educational attainment and the risk of NAFLD is less clear in China. Methods: A cross-sectional study including over 200,000 Chinese adults across mainland China was conducted. Information on education level and lifestyle factors were obtained through standard questionnaires, while NAFLD and advanced fibrosis were diagnosed using validated formulas. Outcomes included the risk of NAFLD in the general population and high probability of fibrosis among patients with NAFLD. Logistic regression analysis was employed to estimate the risk of NAFLD and fibrosis across education levels. A causal mediation model was used to explore the potential mediators. Results: Comparing with those receiving primary school education, the multi-adjusted odds ratios (95% confidence intervals) for NAFLD were 1.28 (1.16 to 1.41) for men and 0.94 (0.89 to 0.99) for women with college education after accounting for body mass index. When considering waist circumference, the odds ratios (95% CIs) were 0.94 (0.86 to 1.04) for men and 0.88 (0.80 to 0.97) for women, respectively. The proportions mediated by general and central obesity were 51.00% and 68.04% for men, while for women the proportions were 48.58% and 32.58%, respectively. Furthermore, NAFLD patients with lower educational attainment showed an incremental increased risk of advanced fibrosis in both genders. Conclusions In China, a low education level was associated with a higher risk of prevalent NAFLD in women, as well as high probability of fibrosis in both genders.

OBJECTIVE To investigate the inhibitory effect and the possible mechanism of hydrogen sulfide （H2S） on the proliferation of cardiac fibroblasts. METHODS The heart of neonatal SD rats was collected， and cardiac fibroblasts were separated with differential centrifugation. Using sodium hydrosulfide as the donor of H2S， the effects of H2S on the proliferation of cardiac fibroblasts induced by angiotensin Ⅱ （Ang Ⅱ）， hydroxyproline content and the expression of sirtuin 3 （SIRT3） protein were detected. After SIRT3 knockdown with siRNA technology， the effects of H2S on the proliferation of cardiac fibroblasts induced by Ang Ⅱ， hydroxyproline content， the expressions of collagen Ⅰ （Col Ⅰ）， collagen Ⅲ （Col Ⅲ ） and optic atrophy protein 1 （OPA1） were detected. RESULTS H2S could inhibit the proliferation of Ang Ⅱ-induced cardiac fibroblasts， reduce the content of hydroxyproline and increase the expression of SIRT3 （P＜0.05）. After down-regulating the expression of SIRT3 with siRNA technology， the inhibition of H2S on the proliferation of Ang Ⅱ-induced cardiac fibroblasts and the reduction of hydroxyproline content were both inhibited， and the effect of H2S on reducing the expression of Col Ⅰ and Col Ⅲ and enhancing the expression of OPA1 was also significantly weakened. CONCLUSIONS H2S inhibits the proliferation of Ang Ⅱ -induced cardiac fibroblasts through increasing the expression of SIRT3.

Objective:To establish a decision tree model of pediatric complicated appendicitis (CA) based on Pediatric Appendicitis Score (PAS) combined with inflammatory indicators, and to evaluate its clinical application efficacy in pediatrics.Methods:The clinical data of 544 children diagnosed with appendicitis in Children′s Hospital Affiliated to Shanghai Jiao Tong University School of Medicine from January 2018 to December 2021 was retrospectively analyzed. According to postoperative pathology, the children were divided into uncomplicated appendicitis group and CA group. The independent risk factors of CA were screened by univariate and multivariate logistic regression analysis, and these parameters were included to establish the decision tree model. The accuracy of the decision tree model was verified by receiver operating characteristic (ROC) curve.Results:Binary logistic regression analysis indicated that the PAS, C-reactive protein (CRP) and neutrophil to lymphocyte ratio (NLR) were identified as independent risk factors for complicated appendicitis in children (all P<0.05). PAS, CRP and NLR were included as covariables to construct the decision tree model and binary logistic regression model for predicting CA. The decision tree demonstrated an overall accuracy of 79.2% with a sensitivity of 86.7% and specificity of 71.9%, and achieved an area under curve (AUC) of 0.821(95% CI: 0.786-0.857). The binary logistic regression model had a sensitivity of 79.6% and specificity of 69.1%, with an overall accuracy of 75.1% and achieved an AUC of 0.808(95% CI: 0.770-0.845). Conclusions:The decision tree model based on PAS score combined with CRP, NLR is a simple, intuitive and effective tool , which can provide pediatric emergency physicians a reliable basis for diagnosis of pediatric CA.

Peptides are increasingly important resources for biological and therapeutic development, however, their intrinsic susceptibility to proteolytic degradation represents a big hurdle. As a natural agonist for GLP-1R, glucagon-like peptide 1 (GLP-1) is of significant clinical interest for the treatment of type-2 diabetes mellitus, but its in vivo instability and short half-life have largely prevented its therapeutic application. Here, we describe the rational design of a series of α/sulfono-γ-AA peptide hybrid analogues of GLP-1 as the GLP-1R agonists. Certain GLP-1 hybrid analogues exhibited enhanced stability (t _1/2 > 14 days) compared to t _1/2 (<1 day) of GLP-1 in the blood plasma and in vivo. These newly developed peptide hybrids may be viable alternative of semaglutide for type-2 diabetes treatment. Additionally, our findings suggest that sulfono-γ-AA residues could be adopted to substitute canonical amino acids residues to improve the pharmacological activity of peptide-based drugs.
