Cardiovascular diseases （CVD），a group of common diseases in clinical practice，are witnessing a steady rise in both incidence and mortality rates，posing a challenge to public health. Gualou Xiebai Banxiatang，originating from Synopsis of the Golden Chamber （《金匮要略》），was initially used to treat severe cases of chest impediment. The formula consists of Trichosanthis Fructus，Allii Macrostemonis Bulbus，Pinelliae Rhizoma，and Baijiu. It has a wide range of clinical applications，with therapeutic effects including moving Qi to relieve depression，activating Yang to dissipate mass，and expelling phlegm to alleviate chest congestion. In recent years，clinical research has confirmed that Gualou Xiebai Banxiatang，with or without modification，used alone or in combination with Western medicine，has definite effects in the treatment of CVD such as hyperlipidemia，coronary atherosclerotic heart disease，hypertension，heart failure，and arrhythmia. It can alleviate disease symptoms and reduce the risk of re-hospitalization. Basic research indicates that the mechanisms of Gualou Xiebai Banxiatang include improving endothelial functions，exhibiting anti-inflammatory properties，countering oxidative stress，preventing apoptosis，inhibiting ventricular remodeling，regulating mitochondrial functions，improving hemorheology，and modulating autophagy and neurotransmitters. This article reviews relevant articles in recent years with focuses on the compatibility，clinical application，and mechanism of Gualou Xiebai Banxiatang. This review is expected to provide a theoretical basis for the mechanism research and clinical application of this formula in treating CVD and to offer ideas and reference for in-depth research.

Objective:To explore the longitudinal predictive relationship between self-neglect and frailty among older adults.Methods:Data were drawn from the Chinese Longitudinal Healthy Longevity Survey conducted in 2011 (T1), 2014 (T2), and 2018 (T3). A total of 1 495 older adults aged≥65 years at T1 who participated in three consecutive surveys and had no missing key variables were included. General demographic information, self-neglect scores, and frailty status were extracted. Spearman correlation analysis was used to examine the association between self-neglect and frailty. Cross-lagged analysis was employed to investigate the potential causal relationship between the two variables.Results:The self-neglect scores for 1 495 older adults at T1, T2, and T3 were (2.84±1.39), (2.47±1.30), and (2.41±1.20), respectively, showing a declining trend. The frailty scores at T1, T2, and T3 were 0 (0, 1.00), 0 (0, 2.00), and 1.00 (0, 2.00), respectively, indicating an increasing trend. Cross-lagged analysis revealed that self-neglect at T1 positively predicted frailty at T2 (β=0.076, P=0.004). Frailty at both T1 and T2 positively predicted self-neglect at T2 (β=0.057, P=0.044) and T3 (β=0.058, P=0.029), respectively. Conclusions:Frailty among older adults positively predicts self-neglect, and self-neglect also has a certain predictive effect on frailty. Medical staff should strengthen early screening and intervention for frailty in older adults to delay the occurrence and progression of self-neglect.

OBJECTIVE To investigate the use of common disposable and reusable supplies for prevention and con-trol of infections in Shanghai.METHODS A survey was conducted for the use and reuse of disposable high-value consumables,disposable bronchoscopes and environmental cleaning and disinfection tools in Shanghai by using structured questionnaire.RESULTS Totally 81 medical institutions were involved in the survey,44(54.32％)of which were tertiary hospitals,and the median number of beds was 500.The orthopedic implants(70.37％),ul-trasound knife(69.14％)and endoscopic puncture instrument(66.67％)were the high-value consumables rank-ing the top 3 utilization rates.There was reuse of 18 types of high-value consumables in total among the 12 medi-cal institutions.The major causes of reuse of high-value consumables included fee less tan cost of consumables(58.33％)or being unable to included in charge items(33.33％).27.78％of the recycle high-value consumables were not treated with a dedicated disinfection and sterilization system and procedures for the disposable high-value consumables,and 33.33％did not have the report systems for related adverse reactions.49.09％of the medi-cal institutions reported to use the disposable bronchoscopes,4 of which reused them.The majority of the medi-cal institutions could carry out centralized cleaning and disinfection for the recycled floor cloths(60.81％)and cloth towels(56.76％),and 32.43％of the medical institutions reused the cloth towels by manual cleaning.The utilization rate of antiseptic wipes was 75.41％in adult intensive care unit,62.50％in neonatal intensive care unit.CONCLUSION The study reveals that there are some problems in the use of disposal and reusable supplies for prevention and control of infections,which may provide baseline data for management of the related supplies and the surveillance of disinfection of the recycled supplies so as to enhance the quality of management of hospital-asso-ciated infections.

Objective: To study the impact of sleep characteristics on myopia, among lower primary school students in Shanghai, so as to provide foundation for the prevention of the onset and development of myopia. Methods: A total of 636 students from the first and second grades of two primary schools in Jiading District, Shanghai, were selected through cluster random sampling for questionnaire surveys and ophthalmological examinations in October 2022. The Childrens Sleep Habits Questionnaire (CSHQ) was used to assess sleep quality at baseline. Ophthalmological examinations were conducted in October 2023(479), during which the students study time, screen time and outdoor activity time were monitored for twoweek, repeated twice. Generalized multivariable Logistic regression models and linear regression models were employed to examine the association between sleeprelated factors and myopia, as well as the strength of this association. Results: The baseline survey indicated a myopia prevalence of 18.58%, with 17.18% at followup. The average CSHQ total score was (51.58±4.44), and the average daily sleep duration was (9.43±4.84)h/d, with only 11.6% of participants meeting the recommended sleep sufficiency. Multivariable regression models indicated that insufficient sleep showed positive association with myopia (OR=1.64, 95%CI=1.05-2.56), while bedtime duration was significantly negative associated with myopia (OR=0.74, 95%CI=0.63-0.91, P＜0.05), adjusting for confounding factors. Inconsistency in bed rest time was a risk factor for myopia (OR=1.07, P<0.05), and the consistency of bed rest time, and wakeup time showed statistically significant correlations with SE (P<0.05). There was also statistically significant correlations between consistency in sleep time, bed rest time, and wakeup time with AL (P<0.05). Conclusions Insufficient sleep and bedtime duration are correlated with the onset and progression of myopia. It is critical to ensure sufficient sleep duration and regular sleep habits for children to reduce the occurrence of myopia in the primary school students.

Objective:To explore the efficacy of long intramedullary nails versus short intramedullary nails in the treatment of AO/OTA 31-A3 intertrochanteric fractures.Methods:A retrospective analysis was conducted on 60 patients with AO/OTA 31-A3 intertrochanteric femur fractures treated between March 2019 and August 2022. The patients were randomly divided into two groups (the long nail group and the short nail group). Thirty-four patients were treated with long intramedullary nails, including 16 males and 18 females, aged 68.41±17.84 years old (range 31-96 years). Twenty-six patients were treated with short intramedullary nails, including 13 males and 13 females, aged 72.23±13.97 years old (range 31-90 years). The causes of injury, fracture classification (AO/OTA classification), intraoperative blood loss, operation time, fracture healing time, imaging indexes (fracture reduction quality, postoperative neck trunk angle, and medial support), Harris score of the hip joint at the last follow-up, one-year mortality rates and complications were compared between the two groups.Results:The follow-up time was 24.26±6.67 months in the long nail group and 24.31±5.60 months in the short nail group, and the general information of the two groups were comparable. Between the long nail and short nail group, the intraoperative blood loss was 281.47±235.28 ml vs. 121.92±84.14 ml and the operation time was 110.44±24.63 min vs. 81.15±28.54 min with significant differences ( P<0.05). While the length of hospital stay was 12.35±4.81 d vs. 10.89±4.30 d, the good rate of fracture reduction was 55.9% vs. 61.53%, the fracture healing time was 120.44±16.43 d vs. 128.07±18.33 d, the presence rate of medial support was 67.6% vs. 79.4%, and the excellent rate of Harris score was 65.4% vs. 65.4% with no significant difference between the two groups ( P>0.05). One-year mortality rates was 5.3% vs. 7.1% and complications was 11.7% vs. 15.4% with no significant difference between the two groups ( P>0.05). Conclusion:Both long intramedullary nails and short intramedullary nails are effective in the treatment of AO/OTA 31-A3 intertrochanteric femur fractures. However, surgical time and intraoperative blood loss was less in the short nail group.

Pathological vascular remodeling is a hallmark of various vascular diseases. Previous research has established the significance of andrographolide in maintaining gastric vascular homeostasis and its pivotal role in modulating endothelial barrier dysfunction, which leads to pathological vascular remodeling. Potassium dehydroandrographolide succinate (PDA), a derivative of andrographolide, has been clinically utilized in the treatment of inflammatory diseases precipitated by viral infections. This study investigates the potential of PDA in regulating pathological vascular remodeling. The effect of PDA on vascular remodeling was assessed through the complete ligation of the carotid artery in C57BL/6 mice. Experimental approaches, including rat aortic primary smooth muscle cell culture, flow cytometry, bromodeoxyuridine (BrdU) incorporation assay, Boyden chamber cell migration assay, spheroid sprouting assay, and Matrigel-based tube formation assay, were employed to evaluate the influence of PDA on the proliferation and motility of smooth muscle cells (SMCs). Molecular docking simulations and co-immunoprecipitation assays were conducted to examine protein interactions. The results revealed that PDA exacerbates vascular injury-induced pathological remodeling, as evidenced by enhanced neointima formation. PDA treatment significantly increased the proliferation and migration of SMCs. Further mechanistic studies disclosed that PDA upregulated myeloid differentiation factor 88 (MyD88) expression in SMCs and interacted with T-cadherin (CDH13). This interaction augmented proliferation, migration, and extracellular matrix deposition, culminating in pathological vascular remodeling. Our findings underscore the critical role of PDA in the regulation of pathological vascular remodeling, mediated through the MyD88/CDH13 signaling pathway.

ObjectiveTo analyze the surveillance results of foodborne diseases in Wuhan to investigate the temporal, spatial, and demographic distribution of foodborne disease in Wuhan, so as to provide an evidence for the prevention and control of foodborne diseases. MethodsData were collected through the foodborne disease surveillance network system and analyzed statistically. Stool, blood, rectal swabs, and vomitus samples from some diarrhea cases were collected for pathogens detection, including Salmonella, Shigella, Escherichia coli, Vibrio parahaemolyticus, and norovirus. ResultsA total of 14 733 cases of foodborne diseases were reported in Wuhan from 2019 to 2022, with a male-to-female ratio of 1∶0.92. The highest incidence was 3.58 per 10 000 person-years in 2019 and the lowest was 2.19 per 10 000 person-years in 2020. The peak incidence occurred from June to October. Higher incidence rates were observed in central districts such as Jiang’an District, Wuchang District, and Caidian District. The age group with the highest incidence was 20‒29 years, while the age group with the highest total pathogen detection rate was 0‒9 years old. The affected population primarily included middle school students, household workers, and unemployed individuals, and children living at home. Suspected food sources were mainly vegetarian, other miscellaneous foods, and animal-based food. Of the 3 499 biological samples collected, 1 820 of them was conducted a detection for norovirus, the overall detection rate of pathogenic bacteria was 22.89% (801/3 499), with detection rates of Salmonella and Escherichia coli at 19.23% (673/3 499) and 3.03% (106/3 499), respectively. The detection rate of norovirus was 4.12% (75/1 820). The detection rate of pathogenic bacteria in biological samples of the patients who consumed infant food, milk, and egg-based foods was higher, at 53.33% and 42.93%, respectively. In terms of detected pathogens, the highest detection rate of Salmonella was found in the biological samples of patients who consumed infant food, milk, and egg-based foods, the highest detection rate of Escherichia coli was found in the biological samples of patients who consumed milk, egg, and animal-based foods, while Vibrio parahaemolyticus and norovirus had higher detection rates in patients who consumed beverages and alcoholic drinks. Suspected food sources were often found in food services, retail or farmer products markets, and homemade food. Salmonella, Vibrio parahaemolyticus, and diarrheagenic Escherichia coli were detected more frequently from June to September, while norovirus was detected more frequently in winter and spring. ConclusionThe population aged between 0‒29 years in Wuhan is the key high-risk group for foodborne diseases. Salmonella, diarrheagenic Escherichia coli, and norovirus are the main pathogens causing foodborne diseases in Wuhan. Market supervision departments should focus on strengthening the regulation of infant food.
