This article systematically reviews the current research status as well as diagnosis and treatment strategies of traditional Chinese medicine （TCM） for gastroesophageal reflux disease （GERD）. Studies demonstrate that TCM， based on the "disease-syndrome combination" approach， exhibits multi-target advantages in alleviating symptoms of various GERD subtypes， promoting mucosal repair， regulating emotions， and facilitating the reduction of western medication. To address clinical challenges such as symptom overlap and limited therapeutic efficacy， strategies have been proposed including "treating different diseases with the same method" and integrated regulation based on viscera correlation. Future efforts should focus on elucidating the mechanisms of compound prescriptions， promoting TCM drug development under the "three-combination" evaluation framework that integrates TCM theory， human experience and clinical trial evidence， and optimizing integrated traditional and western medicine models to enhance GERD management.

Background/Aims: Non-pharmacological treatments are crucial for managing irritable bowel syndrome (IBS), yet patient engagement remains a challenge. Understanding patients' knowledge, attitudes, and practices regarding these treatments is essential for improving care. Methods: A cross-sectional study was conducted across 5 hospitals, from October 2023 to February 2024. A self-designed knowledge, attitudes, and practices questionnaire along with the IBS quality of life and IBS severity scoring system was administered, and 496 valid responses were analyzed. Statistical analyses included correlation tests, multivariate linear regression, and mediation effect analysis. Results: The median scores for knowledge, attitude, and practice were 28, 25.5, and 21, respectively. Significant positive correlations were found between knowledge-attitude (r = 0.195), knowledge-practice (r = 0.364), and attitude-practice (r = 0.151). The multivariate linear regression analysis further indicated that knowledge (β = 0.399, P < 0.001) and attitude (β = 0.219, P = 0.022) positively correlated with the practical performance. SEM revealed that knowledge had a significant direct effect on both attitude (β = 0.186, P = 0.013) and practice (β = 0.356, P = 0.006). However, the direct effect of attitude on practice was not significant, and attitude did not mediate the relationship between knowledge and practice. Conclusions IBS patients exhibit a significant gap between their positive attitudes and their actual practices concerning non-pharmacological treatments. Knowledge is a direct driver of practice, but positive attitudes alone are insufficient to translate into behavior. Healthcare providers must move beyond simply fostering positive attitudes and focus on targeted educational interventions that provide actionable knowledge and skills to improve patient outcomes.

Objective To investigate the epidemiological characteristics of malaria and provide a basis for developing improved prevention and control measures. Methods Data were obtained from the Chinese Disease Prevention and Control Information System. Malaria surveillance data for Nanning City from January 1,2023, to December 31,2024, were exported from the Infectious Disease Reporting Information Management Subsystem. The characteristics of the two groups of malaria cases were compared. Results A total of 103 imported malaria cases were reported in Nanning City in 2024, representing a 38.32% decrease compared with the same period of the previous year. No statistically significant difference were observed between cases reported in 2023 and 2024 in terms of average age, gender ratio, proportion of parasite species, and monthly reporting distribution;however, statistically significant differences were found in the proportion of reporting areas and current residence areas(χ2= 13.572 and 10.355, respectively; P = 0.001 and 0.035, respectively). The proportion of cases reported in Shanglin County and the proportion of cases residing in Shanglin County were both lower than those during the same period of the previous year. Conclusions The high aggregation of imported malaria cases in Nanning City has decreased. Medical institutions in areas other than Shanglin County should strengthen their vigilance against malaria.

The global incidence rate of cancer is increasing yearly,and chemotherapy-induced gastrointestinal mucosal injury has become a crucial factor affecting patients'therapeutic prognosis;however,there is currently a lack of effective therapeutic drugs to address this issue.There is thus an urgent need to establish more ideal animal models of chemotherapy-induced gastrointestinal mucosal injury,to support the exploration of its pathogenesis and the development of therapeutic drugs.This review considered relevant literature published during the period from 2019 to 2024,to provide a comprehensive summary and analysis from several perspectives,including the selection of experimental animals,chemotherapeutic drugs and modeling method,evaluation indicators,and practical applications.Furthermore,we highlight several existing issues with current models,including the lack of standardized modeling method,insufficient research on models with a tumor background,and inadequate exploration of novel cell death mechanisms.This collation of the literature also revealed the gradual emergence of traditional Chinese medicine as a research hotspot,with potential for the treatment of gastrointestinal mucosal injury.Further studies of effective medicines are warranted to identify interventional strategies for chemotherapy-induced gastrointestinal mucosal injury.

Objective:To understand the prevalence of frailty and the importance of its influencing factors in adult population in Shaanxi Province.Methods:The data were from Shaanxi baseline survey of natural population cohort study in northwest China during 2018-2019. The frailty index (FI) was constructed to evaluate the frailty status of the population, and XGboost model combined with Shapley method was used to analyze the importance of the sociodemographic and life behavior factors affecting the prevalence of frailty by gender and age.Results:A total of 25 079 subjects were included, in whom 964 (3.8%) had frailty, and there was no significant difference in the overall prevalence of frailty between women (3.9%) and men (3.8%) ( P=0.629), but there was a gender specific difference in the distribution of FI ( P<0.001), and the proportion of the pre-frailty in men was higher than that in women. The prevalence of frailty increased with age ( P<0.001), the prevalence of frailty were 1.3%, 2.5% and 7.8% in young, middle-aged and elderly women, respectively, and 1.9%, 2.7% and 5.5% in young, middle-aged and elderly men, respectively. Sociodemographic characteristics and lifestyle patterns were both influencing factors for the prevalence of frailty, but their importance varied with gender and age. The top five contributing factors were education level, staying up late, annual family income level, sedentary time and marital status in young women, and staying up late, smoking, annual family income level, sedentary time and drinking in young men. The top five contributing factors were education level, annual family income level, passive exposure to smoking, staying up late, and sedentary time in middle-aged women, and annual family income level, education level, sedentary time, staying up late and drinking in middle-aged men. The top five contributing factors were annual family income level, passive exposure to smoking, sedentary time, marital status, and smartphone use in elderly women, and education level, annual family income level, smoking, smartphone use and sedentary time in elderly men. Conclusions:There are gender specific differences in the distribution of FI in Shaanxi. The prevalence of frailty increased with age, but young and middle-aged people also have frailty risk. The prevalence of frailty in young men was mainly related to unhealthy life behaviors, such as staying up late, smoking, sedentary behavior and drinking, while the prevalence of frailty in middle-aged and elderly men and women were more affected by sociodemographic factors, such as education level, economic status and marital status.

Objective:To investigate the regulatory effect of leptin via the JAK2/STAT3 pathway on the core-binding factor β-subunit (CBFβ) and its molecular mechanism in promoting chondrocyte apoptosis.Methods:A total of five patients undergoing total knee arthroplasty due to knee osteoarthritis (OA group) and five patients undergoing amputation due to trauma (amputation group) were enrolled, and knee cartilage samples were obtained intraoperatively. Western blotting was used to detect the protein expression levels of leptin, CBFβ, matrix metalloproteinase-1 (MMP1), and MMP13. Flow cytometry was performed to determine the optimal treatment duration and concentration of leptin. Chondrocytes were divided into the following groups based on treatment conditions: control group (untreated chondrocytes), leptin group (chondrocytes treated with 50 ng/ml leptin), negative leptin group (chondrocytes transfected with a non-targeting sequence as a control), and leptin+shCBFβ group (chondrocytes transfected with shCBFβ to inhibit CBFβ expression). Apoptosis and the expression levels of MMP1 and MMP13 were analyzed in the four groups. Additionally, chondrocytes were categorized into the following groups for further analysis: control group (untreated cells), leptin group (cells stimulated with 50 ng/ml leptin for 48 h), AG490 group (cells treated with the JAK2/STAT3 inhibitor AG490), and leptin+AG490 group (cells pretreated with AG490 for 2 h followed by 50 ng/ml leptin stimulation for 48 h). The protein expression levels of CBFβ, MMP1, and MMP13, as well as the apoptosis rate, were examined in the four groups.Results:The relative expression levels of leptin, CBFβ, MMP1, and MMP13 in the amputation group were 0.66±0.06, 0.69±0.06, 0.74±0.05, and 0.41±0.03, respectively, which were significantly lower than those in the OA group (1.04±0.10, 1.06±0.09, 0.95±0.04, and 0.99±0.09, respectively) ( P<0.05). The optimal treatment duration and concentration of leptin were determined to be 48 h and 50 ng/ml, respectively. The expression levels of MMP1 and MMP13 significantly differed among the control, leptin, negative leptin, and leptin+shCBFβ groups ( P<0.05). Specifically, the leptin group showed higher expression levels compared to the control group, while the leptin+shCBFβ group exhibited lower expression levels than the leptin group ( P<0.05). The apoptosis rates of chondrocytes in the four groups were 4.55%±1.30%, 22.52%±2.03%, 22.03%±2.01%, and 5.15%±0.91%, respectively, with significant differences ( F=114.066, P<0.001). The apoptosis rate in the leptin group was significantly higher than that in the control group, while the leptin+shCBFβ group exhibited a significantly lower apoptosis rate than the leptin group ( P<0.05). Similarly, significant differences were observed in the expression levels of CBFβ, MMP1, and MMP13 among the control, leptin, AG490, and leptin+AG490 groups ( P<0.05). The expression levels in the leptin group were higher than those in the control group, while the leptin+AG490 group exhibited lower expression levels compared to the leptin group ( P<0.05). The apoptosis rates of chondrocytes in the control, leptin, AG490, and leptin+AG490 groups were 5.19±0.94%, 31.52±2.63%, 5.51±1.41%, and 10.47±0.85%, respectively, with significant differences ( F=117.104, P<0.001). The apoptosis rate in the leptin group was significantly higher than that in the control group, while the leptin+AG490 group exhibited a significantly lower apoptosis rate than the leptin group ( P<0.05). Conclusion:Leptin promotes CBFβ expression via the JAK2/STAT3 pathway, leading to chondrocyte apoptosis and extracellular matrix degradation.

OBJECTIVE To observe the epidemiological characteristics,virulence and drug resistance genes in Kleb-siella oxytoca complex(KOX)strains isolated from the children in Suzhou so as to provide theoretical bases for clinical prevention and control.METHODS The clinical distribution and drug resistance of 101 strains of KOX that were isolated from Children's Hospital of Soochow University from Jan.2021 to Mar.2024 were retrospectively analyzed.Fifty strains were randomly selected to detect the expressions of 18 types of virulence genes and 12 types of drug resistance genes.RESULTS Of the 97 strains of KOX isolated from hospitalized children,32.67％from i-solated from sputum,27.72％from stools and 24.74％from urine;45.54％were isolated from hematology de-partment,18.81％from neonatology department and 10.89％from ICU.The strains expressed a variety of viru-lence genes,among which the ironophore-related genes entB(82.00％),irp-1(64.00％),irp-2(64.00％),ybtS(64.00％)and fyuA(64.00％)were dominant.Carbapenem-sensitive KOX(CS-KOX)strains were susceptible to most of the antibiotics,while the drug resistance rates of the CR-KOX strains to most of the antibiotics were relatively high.The detection rates of extended-spectrum β-lactamase gene CTX(56.52％)and carbapenemase gene NDM(78.26％)were relatively high among the CR-KOX strains;38.89％(7/18)of the strains expressed NDM gene and meanwhile expressed other carbapenemase genes.CONCLUSIONS The KOX strains isolated from the hospitalized children in Suzhou carry a variety of virulence and drug resistance genes,and there is risk of trans-mission of CR-KOX in the hospital.Therefore,it is necessary to attach great importance to the surveillance of drug-resistant strains for the long-term hospitalized children and raise the awareness of infection control so as to prevent the transmission of such bacteria.

Objective:To construct a biosafety evaluation index system for major emergency public health events in medical institutions.Methods:Based on previous laboratory biosafety evaluation work, relevant regulations and standards on biosafety in China were collected through literature research and expert consultations. Candidate indicators for constructing the biosafety evaluation system for major emergency public health events in medical institutions were selected, and a framework was established. Two rounds of expert questionnaires were conducted to determine the content of the index system based on experts′ evaluation, and each indicator′s relevance and importance were scored. Finally, two rounds of Delphi consultations were carried out, and the Analytic Hierarchy Process (AHP) was applied to calculate the weights of indicators.Results:The response rates for the total four rounds of questionnaire surveys were all 100%. The first two rounds focused on determining the framework, while the latter two focused on determining the weights for each indicator. The authority coefficients of the expert consultations for the two rounds of weights were 0.65 and 0.70, respectively, indicating the reliability of the research results. In the final round of survey, the Kendall′s coefficients of concordance at each level were all greater than 0.1. Through statistical testing, the P-values were all less than 0.05, indicating good coordination of expert opinions. Ultimately, we established an operational biosafety evaluation system for major emergency public health events in medical institutions, consisting of 4 primary indicators, 26 secondary indicators, and 119 tertiary indicators, with additional deduction items, bonus items, unacceptable items, and monitoring indicators.Conclusions:Based on scientific theory, a biosafety evaluation system for major emergency public health events in medical institutions was constructed, achieving the integration of routine and emergency measures. This system can be used for self-assessment of laboratory biosafety during emergency public health events, addressing the lack of unified standards in biosafety evaluation. Through regular self-assessment, it can enhance the level of biosafety management in medical institution laboratories, to realize the value of application and dissemination.
