ObjectiveThis study aimed to establish a monocrotaline (MCT)-induced pulmonary arterial hypertension (PAH) rat model to systematically evaluate the protective effect of Xiao Qinglongtang (XQLT) on right cardiac function in model rats and further elucidate the underlying regulatory mechanism. MethodsSixty male SD rats were randomly assigned to the normal group, model group, XQLT low-, medium-, and high-dose groups (XQLT-L/M/H), and the beraprost sodium tablet group (BST). Except for the normal group, rats in all other groups were given a single subcutaneous injection of MCT (60 mg·kg-1) to induce PAH. Three weeks after injection, rats in the XQLT-L/M/H groups were administered XQLT intragastrically at 3.07, 6.14, 12.28 g·kg-1·d-1, respectively. Rats in the BST group received beraprost sodium at 12.6 μg·kg-1·d-1, and rats in the model group received an equal volume of saline. All treatments lasted for 3 weeks. Right ventricular systolic pressure (RVSP) was measured by right ventricular catheterization. Cardiac function was assessed by echocardiography. The right ventricle was weighed to calculate the right ventricular hypertrophy index (RVHI). Hematoxylin-eosin (HE) staining, Masson staining, and transmission electron microscopy were used to observe myocardial morphology. Serum metabolomic changes were analyzed using ultra-performance liquid chromatography-tandem mass spectrometry (UPLC-MS/MS). Data-independent acquisition (DIA) proteomics was used to detect differentially expressed (DE) proteins in the right ventricle, and Western blot was used to measure the expression of uncoupling protein 3 (UCP3), phosphatidylinositol 3-kinase catalytic subunit p110α (PIK3CA), L1 cell adhesion molecule (L1CAM), and quinone oxidoreductase (CRYZ). UPLC-MS/MS was used to analyze the chemical components of XQLT. ResultsCompared with the normal group, the model group showed significantly increased RVSP and RVHI (P<0.05), along with pathological changes in myocardial morphology. Compared with the model group, all XQLT-treated groups exhibited reductions in RVSP and RVHI as well as significant improvements in cardiac function and myocardial morphology. Among the XQLT groups, XQLT-M showed the most pronounced effects (P<0.05), comparable to the BST group. Serum metabolomics revealed 105 differential metabolites in the XQLT groups versus the model group [variable importance in projection (VIP) >1, P<0.05], including 58 upregulated and 47 downregulated metabolites. KEGG enrichment analysis indicated that XQLT intervention downregulated phenylalanine metabolism (P<0.01) and upregulated unsaturated fatty acid biosynthesis (P<0.05). Proteomics analysis showed that 982 DE proteins were identified in the MCT groups versus the normal group, including 455 upregulated and 527 downregulated proteins (|fold change (FC)| >1.3, P<0.05). Compared with the model group, 237 DE proteins were identified in the XQLT groups, including 124 upregulated and 113 downregulated proteins (|FC| >1.3, P<0.05), with 57 overlapping DE proteins. KEGG enrichment suggested that XQLT mainly modulated pathways related to mineral absorption, ribosomal biogenesis, peroxisomes, glycolysis/gluconeogenesis, spliceosomes, and thyroid hormone signaling. Western blot analysis showed that, compared with the model group, XQLT increased the expression of UCP3, PIK3CA, and L1CAM, while decreasing the expression of CRYZ (P<0.05). ConclusionXQLT exerts a protective effect on right heart function in MCT-induced PAH rats, and its mechanism is associated with maintaining myocardial homeostasis and alleviating right ventricular remodeling.

OBJECTIVE To investigate the application and influencing factors of sodium-dependent glucose transporters 2 inhibitors(SGLT-2i) in patients with heart failure with preserved ejection fraction(HFpEF) in the real world. METHODS Data from 358 patients with HFpEF who were hospitalized at the First Affiliated Hospital of Chongqing Medical University from May 2023 to May 2024 were retrospectively collected. The patients were divided into the SGLT-2i group and the non-SGLT-2i group based on whether they were prescribed SGLT-2i upon discharge. Baseline characteristics, comorbidities, and differences in drug treatment were compared between the two groups. Based on univariate analysis, multivariate Logistic regression analysis was performed to identify independent influencing factors of SGLT-2i use in patients with HFpEF, followed by further stratified analysis. RESULTS Among 358 HFpEF patients, the overall utilization rate of SGLT-2i was 33.5%. Combined with type 2 diabetes [OR=9.063,95%CI(4.924-16.679) ] , atrial fibrillation [OR=3.135,95%CI(1.590-6.178) ] , coronary artery heart disease [OR=1.888,95%CI(1.072-3.327) ] and the use of loop diuretics [OR=3.822, 95%CI (1.588-9.200) ] were all independent influencing factors for the use of SGLT-2i in patients with HFpEF ( P <0.05). The results of the stratified descriptive analysis were consistent with those of the multivariate analysis, showing a higher utilization rate of SGLT-2i among patients with concomitant T2DM,atrial fibrillation, coronary artery heart disease, and those receiving loop diuretics ( P <0.05); whereas the utilization rate of SGLT-2i was comparable across patients with different levels of renal function ( P >0.05). CONCLUSIONS In the real-world clinical practice, the utilization of SGLT-2i in patients with HFpEF remains suboptimal, and treatment coverage still needs to be improved. Their use of SGLT-2i is primarily influenced by the presence of type 2 diabetes, atrial fibrillation, coronary artery heart disease, and the use of loop diuretics.

Objective:
To review the relationship between 24 hour movement behaviors and physical and mental health among college students, in order to provide evidence to support health promotion and further research in universities.
Methods:
Following the Joanna Briggs Institude(JBI) scoping review guidelines, relevant studies published in databases from inception date to December 26, 2025 were searched, including PubMed, Embase, Cochrane Library, Web of Science, China National Knowledge Infrastructure (CNKI) and Wanfang Data. For studies meeting the inclusion and exclusion criteria, a descriptive analysis was conducted to summarize the measurement tools used, adherence rates with guidelines, and the relationship between physical and mental health.
Results:
A total of 30 studies were included. Measurement tools exhibited a high heterogeneity, with questionnaires being the primary method. The rate of full adherence with 24 hour movement behaviors among college students was less than 30%. Moderate to vigorous physical activity and high quality sleep were associated with improvements in physical fitness, cardiopulmonary function, and mental health, while prolonged sitting was negatively associated with obesity and depression. Equivalent time substitution analysis indicated that increasing moderate to vigorous physical activity and reducing prolonged sitting could significantly improve health outcomes.
Conclusions
The adherence rate for 24 hour movement behaviors among college students is low and it is closely associated with physical and mental health. Future studies should standardize measurement tools, and implement targeted interventions based on the optimization of daily activity patterns.
4.Related factors and pathway analysis of e-cigarette use behavior among primary and secondary school students in Pudong New Area,Shanghai
Chinese Journal of School Health 2026;47(6):795-798
Objective:
To examine the prevalence of e-cigarette use and associated factors among primary and secondary school students in Pudong New Area, Shanghai, and to explore the pathways linking harm perception of e-cigarettes, interpersonal social influence, and attitudes toward e-cigarette use with experimentation behavior, in order to provide scientific basis for further optimizing the prevention and control strategies of e-cigarette among adolescents.
Methods:
From September to October 2025, a multi stage cluster random sampling method was used to select 5 144 primary and secondary school students aged 8-19 years from 47 primary and secondary schools in Pudong New Area, Shanghai, to conduct an anonymous questionnaire survey. The questionnaire collected information on e-cigarette use, harm perception of e-cigarette, interpersonal social influence, and attitudes toward e-cigarette use. The Chi-square test was applied to analyze the differences in cigarette and e-cigarette use behavior among primary and secondary school students with different demographic characteristics. Structural equation modeling (SEM) was constructed using Mplus 8.3 software, and the bootstrap method was utilized to test the mediating effects.
Results:
The reported rates of cigarette experimentation, e-cigarette experimentation, and current e-cigarette use among primary and secondary school students were 1.85%, 2.10%, and 0.70%, respectively. Higher reporting rates of e-cigarette experimentation were observed among boys (2.82%), secondary school students aged 16-19 (3.39%), senior high school students (3.05%), and those with weekly pocket money >100 yuan ( 6.11% ) ( χ 2=11.67, 8.61, 8.00, 54.18, all P <0.05). Structural pathway analysis results demonstrated that e-cigarette harm perception positively predicted interpersonal social influence ( β =0.61) and e-cigarette use attitude ( β = 0.53 ), and interpersonal social influence ( β =0.65) and e-cigarette use attitude ( β =0.25) further promoted e-cigarette experimentation behavior among primary and secondary school students (all P <0.01), with interpersonal social influence playing a major mediating role (indirect effect=0.40).
Conclusions
E-cigarette experimentation behavior among primary and secondary school students in Pudong New Area is jointly influenced by multiple psychosocial factors. Intervention strategies should strengthen interpersonal social factors such as family and peers on the basis of health education, thereby constructing a comprehensive prevention and control strategy for e-cigarette use among primary and secondary school students.

Both type 2 diabetes mellitus (T2DM) and metabolic associated fatty liver disease (MAFLD) fall within the spectrum of metabolic diseases, and they exhibit a bi-directional causal relationship and robust reciprocal association. Their shared pathological cornerstone is insulin resistance (IR), which involves the interplay of mitochondrial dysfunction and chronic inflammation, forming a cascading pathological process of “IR-mitochondrial dysfunction-inflammation”. This largely explains the notable upward trend in T2DM-MAFLD co-occurrence observed over recent years. Exercise intervention, as a safe and effective non-pharmacological approach, can improve the pathological progression of these patients at multiple levels. Following the logical framework of “pathogenesis-efficacy comparison-molecular mechanisms-clinical translation”, this article systematically compares the efficacy and molecular mechanisms of moderate-intensity continuous training (MICT), resistance exercise, high-intensity interval training (HIIT), and combined training. MICT reduces intrahepatic triglycerides by promoting lipolysis and improving cardiorespiratory fitness; resistance exercise increases muscle mass and basal metabolic rate, offering unique advantages in preserving muscle while reducing fat and improving insulin sensitivity; HIIT is a time-efficient exercise modality that enhances patients’ cardiorespiratory fitness and insulin sensitivity by alternating brief periods of vigorous exertion with recovery periods, with a prominent short-term triglyceride-lowering effect; combined training produces synergistic effects, comprehensively improving glucolipid metabolism and showing the best long-term adherence. Mechanistically, exercise exerts its beneficial effects through three common pathways: (1) AMPK-mediated lipid oxidation and mitochondrial biogenesis; (2) IRS/PI3K/Akt-mediated insulin signaling sensitization; and (3) Nrf2/ARE anti-oxidation and TGF-β/Smads anti-fibrosis regulation. Different exercise modalities activate these pathways with distinct emphases: MICT most directly and persistently activates the AMPK pathway; resistance exercise uniquely improves IRS/PI3K/Akt signaling through muscle mass gain; HIIT induces the highest AMPK activation intensity and triggers unique lactate-mediated signaling regulation; combined training integrates the above multiple mechanistic advantages. For clinical translation, multidisciplinary team collaboration is essential to ensure safety and adherence. Individualized prescriptions should be formulated according to the FITT-VP principle and patient phenotypes—frequency of 3-5 sessions/week of aerobic exercise combined with 2-3 sessions/week of resistance exercise; intensity of moderate-intensity (40%-60% heart rate reserve (HRR))aerobic exercise and 60%-80% of one-repetition maximum (1-RM) for resistance exercise; time of at least 150 min/week of moderate-intensity aerobic exercise, 30-60 min per session; type of combined training as the preferred modality; total volume of≥500-1 000 MET-min/week; and progression adjusted every 4-6 weeks—with real-time adjustments supported by wearable devices, ultimately forming a closed-loop management system from initial assessment to long-term follow-up. Notably, current studies have limitations such as small sample sizes and short intervention periods. Future research should focus on long-term follow-up, multi-omics biomarkers, and combined exercise-drug strategies. In conclusion, the systematic integration of structured, individualized, and sustainable exercise interventions into the multidisciplinary management pathway for patients with T2DM complicated by MAFLD is an urgent need in current clinical practice.

Objective To understand the awareness and willingness of primary medical staff in Songjiang District, Shanghai towards human papillomavirus (HPV) and its vaccines, and to provide references for improving the vaccination willingness of HPV vaccine and primary prevention of cervical cancer. Methods From July to August 2023, a questionnaire survey was conducted among the in-service medical staff in 17 community health service centers in Songjiang District, Shanghai, using the random sampling method. Descriptive analysis, χ2 test and logistic regression were used for statistical analysis. Results A total of 951 valid questionnaires were collected during the survey. The awareness rate of HPV among medical staff was 92.74%, and the awareness rate of HPV vaccine was 93.38%. The maximum score for HPV knowledge was 6 points, with an average score of (3.99±1.34) points. The maximum score for HPV vaccine knowledge was 10 points, with an average score of (5.63±1.61) points. 881 (92.64%) medical staff were willing to receive or recommend HPV vaccination. Multivariate analysis showed that concerns about being infected with HPV (OR=2.648, 95% CI: 1.459-4.806), qualified score on HPV vaccine knowledge (OR=1.717, 95% CI: 1.012-2.912), high price burden of HPV vaccine (OR=0.343, 95% CI: 0.157-0.746), and concerns about side effects of vaccination (OR=0.443, 95% CI: 0.243-0.805) were the influencing factors for medical staff's willingness to vaccinate. Conclusion There is insufficient knowledge of HPV and its vaccines among primary medical personnel in Songjiang District, Shanghai. It is necessary to strengthen the continuing education of medical personnel through multiple channels, supplement the HPV-related knowledge system, and eliminate their concerns about vaccines.

ObjectiveTo improve the therapeutic effect of Buyang Huanwutang(BYHW) on diabetic kidney disease (DKD) and explore new methods for developing new Chinese medicine decoctions,we utilized 5-hydroxymethylcytosine (5hmC)-Seal sequencing technology and network pharmacology to modify BYHW. MethodsWe selected 14 diabetes mellitus (DM) patients and 15 DKD patients hospitalized in the Department of Endocrinology of Peking University Third Hospital in 2021. Circulating free DNA (cfDNA) in the patients’ plasma was sequenced. After data processing and screening, we performed temporal clustering analysis to select a DKD 5hmC gene set, which was then cross-validated with a DKD database gene set to obtain the DKD gene set. We retrieved target genes of the seven herbal components of BYHW from the Traditional Chinese Medicine Systems Pharmacology Database and Analysis Platform (TCMSP) and the Encyclopedia of Traditional Chinese Medicine (ETCM), and performed cross-analysis with the DKD gene set to identify common genes shared by the disease and the Chinese medicines. A protein-protein interaction (PPI) network was constructed for the common genes to screen out the key genes. Chinese medicines targeting these key genes were searched against ETCM to identify removable Chinese medicines. Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis was performed on non-common DKD genes, and key genes in DKD-related pathways were selected based on machine learning. The GSE30529 dataset was used to verify the expression trends of 5hmC-modified genes and the feasibility of target genes as drug targets. TCMBank was used to search for target genes and obtain compounds targeting these genes and the corresponding Chinese medicines to construct a "key target-compound-Chinese medicine" network. Molecular docking was employed to verify the binding affinity of compounds with key targets. TCMSP and ETCM were used to search and count the candidate Chinese medicines targeting DKD-related genes, and a new decoction was formed by adding the selected Chinese medicines. A mouse model of DKD was established to examine the efficacy of the new decoction based on the mouse body mass, random blood glucose, urinary microalbumin (mALB), serum creatinine (Scr), and blood urea nitrogen (BUN) and by hematoxylin-eosin staining, periodic acid-Schiff staining, Masson staining, immunofluorescence assay, and Real-time PCR. ResultsThe cross-analysis results showed that the DKD gene set included 507 genes, of which 30 were target genes of BYHW. The PPI analysis indicated that the top 15% target genes regarding the degree were interleukin-6 (IL-6), Toll-like receptor 4 (TLR4), lactotransferrin (LTF), lipoprotein lipase (LPL), and sterol regulatory element-binding transcription factor 1 (SREBF1). Persicae Semen and Pheretima in BYHW were unrelated to key genes and removed. Machine learning identified 10 potential target genes, among which TBC1 domain family member 5 (TBC1D5), RAD51 paralog B (RAD51B), and proteasome 20S subunit alpha 6 (PSMA6) had expression trends consistent with the GSE30529 dataset and could serve as drug targets. The "key target-compound-Chinese medicine" network and molecular docking results indicated that the compounds with good binding affinity to target proteins were arginine, glycine, myristicin, serine, and tyrosine, corresponding to 121 Chinese medicines. The top 10 Chinese medicines targeting DKD-related genes were Lycii Fructus, Ginseng Radix et Rhizoma, Dioscoreae Rhizoma, Rehmanniae Radix Praeparata, Isatidis Radix, Glehniae Radix, Ophiopogonis Radix, Allii Sativi Bulbus, Isatidis Folium, and Bolbostemmatis Rhizoma. Based on traditional Chinese medicine theory, the new decoction was obtained after removal of Persicae Semen and Pheretima and addition of Rehmanniae Radix Praeparata and Dioscoreae Rhizoma. Animal experiment results indicated that the modified BYHW improved the kidney function and inhibited renal fibrosis in DKD mice, with better effects than the original decoction. ConclusionThe BYHW modified based on 5hmC-Seal sequencing demonstrates better performance in inhibiting fibrosis and ameliorating DKD than the original decoction. This elucidates the biomedical theory behind the epigenetic modification of traditional Chinese medicine prescriptions, potentially offering new perspectives for the exploration of these prescriptions

ObjectiveThis study explored the risk factors for malignant risks of pulmonary nodules based on clinical data,constructed an integrated traditional Chinese and Western medicine model for predicting malignant risks of pulmonary nodules, and visualized the prediction results by using a nomogram. MethodsBased on a cross-sectional survey study design,patients with pulmonary nodules who were hospitalized in the Department of Respiratory and Cardiothoracic Surgery of Guangdong Provincial Hospital of Traditional Chinese Medicine from April 2023 to January 2024 were included. The dataset was randomly divided into a training set and a validation set according to 7∶3. In the training set,predictive factors were selected through univariate Logistic regression analysis and Least Absolute Shrinkage and Selection Operator (LASSO) regression analysis,and Logistic regression models were built. The discriminative ability,calibration,and clinical decision-making curves of the Western medicine model and the integrated traditional Chinese and Western medicine prediction model were compared to select the optimal model,which was then visualized in a nomogram. ResultsThis study included a total of 366 patients,and they were divided into a training set (258 cases) and a validation set (108 cases). Seven predictive factors were considered including age,preference for fatty and greasy foods,history of environmental or occupational exposure,Qi deficiency,Yang deficiency,nodule density,and nodule diameter. A Logistic regression model was constructed. A Western medicine model,defined as model1,was created using only age,history of environmental or occupational exposure,nodule density,and nodule diameter as predictive factors. In addition,an integrated traditional Chinese and Western medicine model,defined as model2,was created by adding preference for fatty and greasy foods, Qi deficiency,and Yang deficiency as predictive factors. Model2 demonstrated better predictive performance in both the training and validation sets. Its accuracy in training set was 0.740,with precision of 0.825, recall of 0.829, F1 score of 0.827, the area under the curve (AUC)of 0.865 (95% confidence interval (CI):0.815-0.915), and a Brier score of 0.122. The accuracy in validation set was 0.731, with precision of 0.776, recall of 0.831, F1 score of 0.803, AUC of 0.852 (95%CI:0.776-0.927), and a Brier score of 0.149. The calibration curve and decision-making curve analysis showed that this model exhibited good consistency and clinical utility in prediction. The equation for the malignant probability of pulmonary nodules was defined as p=

ObjectiveTo investigate the effects of Scutellariae Radix combined with epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) on cell proliferation, apoptosis, cancer stem cell (CSC) marker expression, and metabolism in non-small cell lung cancer (NSCLC) cells. MethodsThe anti-tumor effects of Scutellariae Radix and EGFR-TKIs (gefitinib or osimertinib) in NSCLC cells were evaluated using the cell counting kit-8 (CCK-8) and Annexin V-FITC/propidium iodide (PI) double staining apoptosis assay. The activity of Scutellariae Radix and EGFR-TKIs in three-dimensional (3D) cultures of NSCLC cells was assessed using the CellTiter-Glo® 3D cell viability assay. The mRNA and protein expression levels of CSC markers, sex determining region y box protein 2 (SOX2) and aldehyde dehydrogenase 1 family member A1 (ALDH1A1), were detected by quantitative real-time polymerase chain reaction (Real-time PCR) and Western blot, respectively. Changes in intracellular reactive oxygen species (ROS) levels were detected by ROS staining, and the redox ratio was detected by femtosecond laser labeling free imaging (FLI). ResultsUnder both two-dimensional (2D) and 3D culture conditions, compared with the blank group and EGFR-TKI group, the combination group showed significantly reduced cell viability and increased apoptosis rate (P<0.05). Compared with the EGFR-TKI group, the mRNA and protein levels of CSC markers were significantly downregulated in the combination group (P<0.05). Additionally, the redox ratio was significantly elevated (P<0.05), and ROS levels were also increased in the combination group compared with the EGFR-TKI group. ConclusionIn NSCLC cells, Scutellariae Radix enhances the redox ratio and increases ROS levels, thereby inhibiting the expression of CSC markers and strengthening the anti-tumor effects of EGFR-TKIs. This provides a novel molecular mechanism by which Scutellariae Radix may enhance the sensitivity of targeted therapies.
