ObjectiveTo evaluate the impact of yang-reinforcing and blood-activating therapy on the long-term prognosis for patients with dilated cardiomyopathy (DCM) of yang deficiency and blood stasis syndrome. MethodsA retrospective cohort study was conducted involving 371 DCM patients with yang deficiency and blood stasis syndrome. The yang-reinforcing and blood-activating therapy was defined as the exposure factor. Patients were categorized into exposure group (186 cases) and non-exposure group (185 cases) according to whether they received yang-reinforcing and blood-activating therapy combined with conventional western medicine for 6 months or longer. The follow-up period was set at 48 months, and the Kaplan-Meier survival analysis was used to assess the cumulative incidence of major adverse cardiovascular events (MACE) in both groups. Cox regression analysis was used to explore the impact of yang-reinforcing and blood-activating therapy on the risk of MACE, and subgroup analysis was performed. Changes in traditional Chinese medicine (TCM) syndrome score, left ventricular ejection fraction (LVEF), left ventricular fractional shortening (LVFS), left ventricular end-diastolic diameter (LVEDD), and Minnesota Living with Heart Failure Questionnaire (MLHFQ) score were compared between groups at the time of first combined use of yang-reinforcing and blood-activating therapy (before treatment) and 1 year after receiving the therapy (after treatment). ResultsMACE occurred in 31 cases (16.67%) in the exposure group and 47 cases (25.41%) in the non-exposure group. The cumulative incidence of MACE in the exposure group was significantly lower than that in the non-exposure group [HR=0.559, 95%CI(0.361,0.895), P=0.014]. Cox regression analysis showed that yang-reinforcing and blood-activating therapy was an independent factor for reducing the risk of MACE in DCM patients [HR=0.623, 95%CI(0.396,0.980), P=0.041], and consistent results were observed in different subgroups. Compared with pre-treatment, the exposure group showed decreased TCM syndrome score and MLHFQ score, reduced LVEDD, and increased LVEF and LVFS after treatment (P<0.05); in the non-exposure group, TCM syndrome score decreased, LVEF and LVFS increased, and LVEDD reduced after treatment (P<0.05). After treatment, the exposure group had higher LVEF and LVFS, smaller LVEDD, and lower TCM syndrome score and MLHFQ score compared with the non-exposure group (P<0.05). ConclusionCombining yang-reinforcing and blood-activating therapy with conventional western medicine can reduce the risk of MACE in DCM patients with yang deficiency and blood stasis syndrome, meanwhile improving their clinical symptoms, cardiac function, and quality of life.

ObjectiveTo explore the effect and mechanism of Taishan Panshi powder (TSPSP) on inhibiting oxidative stress injury in human chorionic trophoblast cells (HTR-8/SVneo), and to uelucidate the underlying mechanism of TSPSP in the treatment of spontaneous abortion (SA). MethodsGene differential analysis of SA was performed using the Gene Expression Omnibus (GEO) database and correlated with oxidative stress. Network pharmacology was employed to screen the active components of TSPSP, and a "Chinese medicine-component-target-disease" network was constructed to predict the mechanism of action of TSPSP. For in vitro validation experiments, HTR-8/SVneo cells were divided into blank group, model group, TSPSP-containing serum 2.5%, 5%, 10% groups, and nuclear factor E2-related factor 2 (Nrf2) inhibitor group (ML385, 30 μmol·L-1). Except for the blank group, other groups were stimulated with 150 μmol·L-1 H2O2 for 3 h to establish a cell oxidative stress injury model. After successful modeling, the blank group and model group were given 10% blank serum, each TSPSP-containing serum group was treated with the corresponding concentration of drug-containing serum, and the Nrf2 inhibitor group was additionally given 30 μmol·L-1 ML385 on the basis of 10% TSPSP-containing serum. All groups of cells were continuously cultured under the above conditions for 24 h, and then samples were collected for subsequent detection. Cell viability in each group was detected by CCK-8 assay. Cell migration rate was detected by scratch test. The contents of malondialdehyde (MDA), Fe2+, and Glutathione (GSH) were detected by enzyme-linked immunosorbent assay (ELISA). Intracellular reactive oxygen species (ROS) level was detected by a fluorescent probe (DCF-DA). The protein and mRNA expression levels of Kelch-like ECH-associated protein 1 (KEAP1), Nrf2, and forkhead box protein O3 (FoxO3) in cells were detected by immunofluorescence (IF) and real-time quantitative polymerase chain reaction (Real-time PCR). The protein expression levels of KEAP1, Nrf2, FoxO3, Glutathione peroxidase 4 (GPX4), and superoxide dismutase (SOD) in cells were detected by Western blot. ResultsThe GSE76862 and GSE22490 datasets were obtained from the GEO database. Differential gene analyses showed that the KEAP1, Nrf2, and FoxO3 genes were all associated with the disease. After matching with the oxidative stress pathway, nine significantly differential pathways were identified (P<0.05), among which three contained the target genes Nrf2 and FoxO3. A total of 246 active ingredient targets of TSPSP and 2 804 SA-related targets were obtained through network pharmacology, and 154 potential action targets were obtained after taking the intersection. Topological analysis showed that targets such as KEAP1 and Nrf2 exhibited high degree values. GO and KEGG enrichment analyses indicated that the intersection targets were mainly involved in oxidative stress response, FOXO and MAPK signaling pathways, etc. In in vitro experiments, compared with the blank group, the cell viability in the model group was significantly decreased (P<0.01). Compared with the model group, the cell viability in each TSPSP-containing serum group was significantly increased (P<0.01). Compared with the 10% TSPSP-containing serum group, the cell viability in the ML385 group decreased to approximately 70% (P<0.01). Compared with the blank group, the model group showed significantly increased contents of MDA, Fe2+, and ROS, decreased GSH expression (P<0.01), significantly reduced cell migration rate (P<0.01), and increased protein and mRNA expression levels of KEAP1 and FoxO3 (P<0.01), while decreased protein and mRNA expression levels of Nrf2, GPX4, and SOD (P<0.01). Compared with the model group, each TSPSP-containing serum group showed significantly decreased contents of MDA, Fe²⁺, and ROS, increased GSH expression (P<0.01), significantly increased migration rate (P<0.01), significantly decreased protein and mRNA expression levels of KEAP1 and FoxO3 (P<0.05, P<0.01), and significantly increased protein and mRNA expression levels of Nrf2, GPX4, and SOD (P<0.05, P<0.01). Compared with the 10% TSPSP-containing serum group, the ML385 group showed reversed trends in all indicators (P<0.05, P<0.01). ConclusionTSPSP can inhibit H2O2-induced oxidative stress injury of trophoblast cells, and its mechanism of action may be related to the drug activating the KEAP1/Nrf2/FoxO3 signaling pathway.

BACKGROUND:Traditional treatments for corneal alkali burns are limited,especially in controlling inflammation,preventing neovascularization,and inhibiting corneal scarring.Natural,synthetic,or composite materials provide a wide range of treatment options.However,the mechanism by which biomaterials promote corneal alkali burn repair has not yet been systematically understood. OBJECTIVE:To summarize the current research on biomaterials in promoting corneal alkali burn repair in and outside China,and review the mechanism and application of biomaterials in repairing corneal alkali burn. METHODS:The first author searched"cornea,alkali burn,amniotic membrane,hyaluronic acid,collagen,chitosan,polymer materials"as Chinese keywords and"amniotic membrane,hyaluronic acid,collagen,chitosan,polymer,cornea,alkali burn"as English keywords in PubMed,Web of Science,CNKI,and WanFang databases.According to inclusion and exclusion criteria,76 eligible articles were finally included for review. RESULTS AND CONCLUSION:(1)In the field of corneal alkali burn repair,biomaterials such as amniotic membrane,hyaluronic acid,collagen,chitosan,and degradable polymer materials have been widely studied and applied.Each of these biomaterials has its own characteristics,advantages,and disadvantages,and stands out in different aspects.(2)First and foremost,amniotic membranes are considered one of the most promising biomaterials due to their abundance of bioactive factors.They are biocompatible and can regulate the corneal inflammatory response.However,there are issues with donor shortages and susceptibility to infectious diseases.(3)Hyaluronic acid has good moisturizing properties and biocompatibility,and is able to improve the survival rate of corneal cells and increase corneal transparency.(4)The good biocompatibility and scaffold structure of collagen enable the promotion of corneal cell adhesion and proliferation,as well as the reconstruction of corneal tissue structure.(5)Chitosan is recognized for its good biocompatibility and degradability,making it suitable as a carrier for drug delivery and cell transplantation.(6)Degradable polymer materials have good controllability over degradation and can provide a good support and delivery platform for the repair of corneal alkali burns,but further research is needed on their stability and biocompatibility.(7)Overall,there is currently no single biomaterial that can completely address the repair problem of corneal alkali burns,and each biomaterial has its own specific application scenarios and limitations.(8)Future research directions should focus on further improving the properties and structure of biomaterials,exploring more effective combination applications,and deeply understanding the interaction mechanism between biomaterials and corneal tissue,in order to enhance the therapeutic effect of corneal alkali burns and the quality of life of patients.

Objective:
To explore the relationship between school sports environment and physical activity levels of middle school students, so as to provide theoretical and empirical support for optimizing school sports environment and enhance adolescent physical activity.
Methods:
Using multi-stage random cluster sampling, from September to December 2023, 1 329 junior and senior high school students from Xuancheng City of Anhui Province, Lianyungang City of Jiangsu Province, Wuhan City of Hubei Province, Qiqihar City and Suihua City of Heilongjiang Province, and Shenzhen City of Guangdong Province were selected. The International Physical Activity Questionnaire-Short Form (IPAQ-SF) assessed students physical activity levels, and the questionnaire on the characteristics of school sports environment was developed to evaluate the factors of school sports environment. Multivariate ordered Logistic regression was performed to analyze the correlation between school sports environment factors and physical activity levels, and the analytic hierarchy process determined the weight of key influencing factors.
Results:
The results showed that weekly vigorous physical activity time was [60 (25, 90)] minutes, moderate physical activity time was [60 (30, 90)] minutes, light physical activity time was [105 (40, 200)] minutes, and sedentary behavior time was [ 3 300 (2 100, 4 500)] minutes, only 10.53% of the students met World Health Organization physical activity recommendations, and 89.69% of the students averaged >8 h daily sedentary time. Multivariate ordered Logistic regression showed that adequate sports equipment significantly promoted physical activity across all intensities and reduced sedentary time ( OR = 4.97, 11.54, 4.03, 0.11); diverse sports activities improved vigorous and moderate physical activity while reducing sedentary time ( OR =4.20, 14.06, 0.17); and peer encouragement was associated with increased low-intensity physical activities and decreased sedentary time ( OR =10.40, 0.15)( P <0.05). The analytic hierarchy process weighting analysis identified the top three influential factors related to physical activity among middle school students: sufficient sports equipment, varied physical education activities, frequent peer encouragement, the influence weight accounts for 23.55% , 14.18% and 11.77% of the total, respectively.
Conclusion
Key school sports environmental factors for adolescent physical activity level include ensuring adequate sports equipment and class availability, diversifying activity content, fostering peer support, and cultivating an active sports culture and a comprehensive approach encourage students participation in extracurricular physical activities.

OBJECTIVE:
To evaluate the efficacy and safety of a hospital-made resuscitation pack, a Chinese medicinal herbal compound formula designed to enhance recovery in post-bronchoscopy patients.
METHODS:
In this randomized, single-blind, placebo-controlled clinical trial, eligible patients were randomly assigned 1:1 to either the treatment or control groups. The patients in the treatment group applied the resuscitation pack, which contained aromatic compounded Chinese herbs. The patients in the control group applied a hospital-made, single herb placebo pack. Packs were placed on the Tiantu (CV 22) acupuncture point for 4 h as soon as the bronchoscopy finished. Efficacy indicators, such as recovery time, patients' symptoms including nausea and dizziness, and adverse events (AEs) were observed and compared. The outcome indices were evaluated at baseline, 1 and 24 h after the bronchoscopy. Subgroup analysis was further performed by patients' age and depth of sedation.
RESULTS:
When applying generalized estimating equations (GEE) to evaluate the intensity of post-bronchoscopy nausea and vomiting, the intensity was lower in the treatment group (163 cases) compared with the control group (162 cases; 95% CI: 0.004, 0.099, P=0.03]. Also, significantly lower intensity of nausea was observed in the 60-70 years of age subgroup (95% CI: 0.029, 0.169, P=0.006) and deep sedation subgroup (95% CI: 0.002, 0.124; P=0.04). There was no significant difference in dizziness between two groups by GEE (95% CI: -0.134, 0.297; P=0.459). In addition, no serious AEs were observed in either group.
CONCLUSIONS
Our study found that the resuscitation pack markedly improved patients' symptoms by reducing nausea and vomiting after bronchoscopy without AEs, compared with placebo in the perioperative period. (Trial registration No. ChiCTR2000038299).

Atrial fibrillation (AF) is the most common arrhythmia in clinical practice. It has a high prevalence and poor prognosis. The application of antiarrhythmic drugs and even surgery cannot completely treat the disease, and there are many sequelae. AF can be classified into the category of "palpitation" in Chinese medicine according to its symptoms. Acupuncture has a significant effect on AF. The authors find that an important mechanism of acupuncture in AF treatment is to regulate the cardiac vagus nerve. Therefore, this article intends to review the distribution and function of vagus nerve in the heart, the application and the regulatroy effect for the treatment of AF.

OBJECTIVE:
To identify the underlying mechanism by which quercetin (Que) alleviates sepsis-related acute respiratory distress syndrome (ARDS).
METHODS:
In vivo, C57BL/6 mice were assigned to sham, cecal ligation and puncture (CLP), and CLP+Que (50 mg/kg) groups (n=15 per group) by using a random number table. The sepsisrelated ARDS mouse model was established using the CLP method. In vitro, the murine alveolar macrophages (MH-S) cells were classified into control, lipopolysaccharide (LPS), LPS+Que (10 μmol/L), and LPS+Que+acetylcysteine (NAC, 5 mmol/L) groups. The effect of Que on oxidative stress, inflammation, and apoptosis in mice lungs and MH-S cells was determined, and the mechanism with reactive oxygen species (ROS)/p38 mitogen-activated protein kinase (MAPK) pathway was also explored both in vivo and in vitro.
RESULTS:
Que alleviated lung injury in mice, as reflected by a reversal of pulmonary histopathologic changes as well as a reduction in lung wet/dry weight ratio and neutrophil infiltration (P<0.05 or P<0.01). Additionally, Que improved the survival rate and relieved gas exchange impairment in mice (P<0.01). Que treatment also remarkedly reduced malondialdehyde formation, superoxide dismutase and catalase depletion, and cell apoptosis both in vivo and in vitro (P<0.05 or P<0.01). Moreover, Que treatment diminished the release of inflammatory factors interleukin (IL)-1β, tumor necrosis factor-α, and IL-6 both in vivo and in vitro (P<0.05 or P<0.01). Mechanistic investigation clarifified that Que administration led to a decline in the phosphorylation of p38 MAPK in addition to the suppression of ROS expression (P<0.01). Furthermore, in LPS-induced MH-S cells, ROS inhibitor NAC further inhibited ROS/p38 MAPK pathway, as well as oxidative stress, inflammation, and cell apoptosis on the basis of Que treatment (P<0.05 or P<0.01).
CONCLUSION
Que was found to exert anti-oxidative, anti-inflammatory, and anti-apoptotic effects by suppressing the ROS/p38 MAPK pathway, thereby conferring protection for mice against sepsis-related ARDS.
