Objective To analyze the epidemiological characteristics of norovirus outbreaks in Haidian District, Beijing, and to provide a reference for epidemic prevention and control. Methods Descriptive epidemiological methods were used to organize and statistically analyze the norovirus outbreak data reported from 2016 to 2022. Results A total of 26 outbreaks of norovirus were reported in Haidian District, with a total of 1595 cases and an attack rate M (Q_R) of 8.23 (16.33)%. There were 24 cases of norovirus type GII (92.31%), 1 case of type GI (3.85%), and 1 case of mixed infection of virus type GI/GII (3.85%). The highest number of reported outbreaks occurred in March and April, with 17 cases, accounting for 65.38%. The highest number of reported cases was in November and December, with 785 cases, accounting for 44.92%. The case age M (Q_R) was 18 (14) years old. The detection rate of positive samples in different age groups had statistical significance（χ²=12.021, P=0.007). The 26 outbreaks were mainly distributed in collective units such as schools, preschool institutions, and enterprises and institutions. There were a total of 11 outbreaks related to foodborne transmission, with 923 cases, accounting for 57.87%. Diarrhea was positively correlated with the age of the cases (r_s=0.572, P<0.001), while vomiting was negatively correlated with the age of the cases (r_s=-0187, P<0.001). The time interval between the onset of acute gastroenteritis symptoms in the first case and the reporting of the epidemic was positively correlated with the duration of the epidemic (r_s=0.586, P=0.002). Conclusion It is necessary to strengthen the prevention and control of norovirus in schools (primary and secondary schools and colleges), strictly implement health monitoring and regular screening for kitchen workers, carry out publicity and education, detect cases as early as possible, report the epidemic in a timely manner, and effectively reduce the scale of the epidemic and prevent its spread.

With the rapid development of social economy and the continuous improvement of human living standard, the incidence, fatality and recurrence rates of cardiovascular disease (CVD) are increasing year by year, which seriously affects people's life and health. Conventional therapeutic drugs have limited improvement on the disability rate, so the search for new therapeutic drugs and action targets has become one of the hotspots of current research. In recent years, the therapeutic role of the natural compound rosmarinic acid (RA) in CVD has attracted much attention, which is capable of preventing CVD by modulating multiple signalling pathways and exerting physiological activities such as antioxidant, anti-apoptotic, anti-inflammatory, anti-platelet aggregation, as well as anti-coagulation and endothelial function protection. In this paper, the role of RA in the prevention of CVD is systematically sorted out, and its mechanism of action is summarised and analysed, with a view to providing a scientific basis and important support for the in-depth exploration of the prevention value of RA in CVD and its further development as a prevention drug.

Following the core outcome set standards for development(COS-STAD), this study aims to construct core outcome set(COS) for clinical research on traditional Chinese medicine(TCM) treatment of simple obesity. Firstly, a comprehensive review was conducted on the randomized controlled trial(RCT) and systematic review(SR) about TCM treatment of simple obesity that were published in Chinese and English databases to collect reported outcomes. Additional outcomes were obtained through semi-structured interviews with patients and open-ended questionnaire surveys for clinicians. All the collected outcomes were then merged and organized as an initial outcome pool, and then a preliminary list of outcomes was formed after discussion by the working group. Subsequently, two rounds of Delphi surveys were conducted with clinicians, methodology experts, and patients to score the importance of outcomes in the list. Finally, a consensus meeting was held to establish the COS for clinical research on TCM treatment of simple obesity. A total of 221 RCTs and 12 SRs were included, and after integration of supplementary outcomes, an initial outcome pool of 141 outcomes were formed. Following discussions in the steering advisory group meeting, a preliminary list of 33 outcomes was finalized, encompassing 9 domains. Through two rounds of Delphi surveys and a consensus meeting, the final COS for clinical research on TCM treatment of simple obesity was determined to include 8 outcomes: TCM symptom scores, body mass index(BMI), waist-hip ratio, waist circumference, visceral fat index, body fat rate, quality of life, and safety, which were classified into 4 domains: TCM-related outcomes, anthropometric measurements, quality of life, and safety. This study has preliminarily established a COS for clinical research on TCM treatment of simple obesity. It helps reduce the heterogeneity in the selection and reporting of outcomes in similar clinical studies, thereby improving the comparability of research results and the feasibility of meta-analysis and providing higher-level evidence support for clinical practice.

OBJECTIVE: Ulcerative colitis is closely associated with intestinal stem cell (ISC) loss and impaired intestinal mucus barrier. Sinisan (SNS), a compound Chinese herbal medicine, has a long history in the treatment of intestinal dysfunction, yet whether SNS can relieve acute experimental colitis by modulating ISC proliferation and secretory cell differentiation has not been studied. Our study tested the effect of SNS against acute colitis and focused on the mechanisms involving intestinal barrier recovery. METHODS: Network pharmacology analysis and blood entry component analysis of SNS were used to explore the underlying mechanism by which SNS affects the acute dextran sulfate sodium (DSS)-induced murine colitis model. RNA-sequencing was used to demonstrate the mechanism. Further, reverse transcription-quantitative polymerase chain reaction, immunofluorescence staining, and alcian blue and periodic acid-Schiff staining were performed in vivo and in the colonic organoids to investigate the cell lineage differentiation-related mechanism of SNS. Furthermore, potential active ingredients from SNS were predicted by network pharmacology analysis. RESULTS: SNS dramatically suppressed DSS-induced acute colonic inflammation in mice. RNA-sequencing analysis revealed downregulation of inflammation and apoptosis-related genes, and upregulation of lipid metabolism and proliferation-related genes, such as Irf7, Pparα, Clspn and Hspa5. Additionally, ISC renewal and intestinal secretory cell lineage commitment were significantly promoted by SNS both in vivo and in vitro in colonic organoids, leading to enhanced mucin expression. Furthermore, potential active ingredients from SNS that mediated inflammation, lipid metabolism, proliferation, apoptosis, stem cells and secretory cells were predicted using a network pharmacology approach. CONCLUSION Our study shed light on the underlying mechanism of SNS in attenuating acute colitis from the perspective of ISC renewal and secretory lineage cell differentiation, suggesting a of novel therapeutic strategy against colitis.

Objective:To explore the possible effects of Bushen Huoxue Formula (the kidney tonifying and blood activating prescription) on the proliferation and extracellular matrix synthesis of nucleus pulposus cells by regulating the circ_0036763/miR-583 axis.Methods:Real time fluorescence quantitative polymerase chain reaction (qRT-PCR) was used to detect the expression levels of circ0036763 and miR-583 in normal and intervertebral disc degeneration (IDD) nucleus pulposus cells; IDD nucleus pulposus cells were divided into pcDNA group, pcDNA circ_0036763 group, pcDNA circ_0036763+ mimic NC group, and pcDNA circ_0036763+ miR-583 mimic group. qRT-PCR was used to detect the expression levels of circ_0036763 and miR-583 in nucleus pulposus cells in each group, methyl thiazolyl tetrazolium (MTT) was used to detect cell proliferation (A value), and Western blot was used to detect the expression of proliferating cell nuclear antigen (PCNA), collagen Ⅰ, and collagen Ⅱ proteins in nucleus pulposus cells, The dual luciferase assay reported experimental validation of the targeting relationship between circ_0036763 and miR-583. 27 mice were divided into sham surgery group, IDD group, and kidney tonifying and blood activating formula group. IDD models were established in all groups except for the sham surgery group. After successful modeling, the sham surgery group and IDD group were given physiological saline by gavage, while the kidney tonifying and blood activating formula group was given 1.5 g/ml of kidney tonifying and blood activating formula by gavage for 3 consecutive weeks. QRT-PCR was used to detect the expression levels of circ0036763 and miR-583 in the nucleus pulposus cells of mice in each group, MTT was used to detect cell proliferation, and Western blot was used to detect the expression of PCNA, collagen Ⅰ, and collagen Ⅱ proteins.Results:The expression level of circ_0036763 in IDD nucleus pulposus cells decreased, while the expression level of miR-583 increased (all P<0.05); Overexpression of circ_0036763 can promote proliferation and extracellular matrix synthesis of nucleus pulposus cells (all P<0.05); Circ_0036763 targets miR-583 and upregulates miR-583 reversible overexpression. Circ_0036763 enhances the proliferation and extracellular matrix synthesis ability of IDD nucleus pulposus cells. Compared with the sham surgery group, the IDD group showed an increase in collagen Ⅰ protein expression and miR-583 expression levels (all P<0.05), while the cell A value, PCNA and collagen Ⅱ protein expression, and circ_0036763 expression levels decreased (all P<0.05); Compared with the IDD group, the Kidney Tonifying and Blood Activating Formula group showed a decrease in collagen Ⅰ protein expression and miR-583 expression levels (all P<0.05), while the cell A value, PCNA and collagen Ⅱ protein expression, and circ_0036763 expression levels increased (all P<0.05). Conclusions:The kidney tonifying and blood activating formula (Bushen Huoxue) may induce proliferation and extracellular matrix synthesis of nucleus pulposus cells by regulating the circ_0036763/miR-583 axis.
