ObjectiveTo examine the influences of Shenfu injection on the endogenous metabolic byproducts in the myocardium of the rat model exhibiting chronic heart failure, thus deciphering the therapeutic mechanism of the Qi-reinforcing and Yang-warming method. MethodsSD rats were randomly allocated into a control group and a modeling group. Chronic heart failure with heart-Yang deficiency syndrome in rats was modeled by multi-point subcutaneous injection of isoproterenol, and the rats were fed for 14 days after modeling. The successfully modeled rats were randomized into model, Shenfu injection (6.0 mL·kg-1), and trimetazidine (10 mg·kg-1) groups and treated with corresponding agents for 15 days. The control group and the model group were injected with equal doses of normal saline, and the samples were collected after the intervention was completed. Cardiac color ultrasound was performed. Hematoxylin-eosin (HE) staining was used to observe histopathological morphology, and the serum level of N-terminal pro-brain natriuretic peptide (NT-proBNP) was assessed by enzyme-linked immunosorbent assay (ELISA). The mitochondrial morphological and structural changes of cardiomyocytes were observed by transmission electron microscopy, and the metabolic profiling was carried out by ultra high performance liquid chromatography-quantitative exactive-mass spectrometry (UHPLC-QE-MS). Differential metabolites were screened and identified by orthogonal partial least squares-discriminant analysis (OPLS-DA) and other methods, and then the MetaboAnalyst database was used for further screening. The relevant biological pathways were obtained through pathway enrichment analysis. The receiver operating characteristic (ROC) curve was established to evaluate the diagnostic value of each potential biomarker for myocardial injury and the evaluation value for drug efficacy. ResultsThe results of color ultrasound showed that Shenfu Injection improved the cardiac function indexes of model rats (P<0.05). The results of HE staining showed that Shenfu injection effectively alleviated the pathological phenomena such as myocardial tissue structure disorder and inflammatory cell infiltration in model rats. The results of ELISA showed that Shenfu injection effectively regulated the serum NT-proBNP level in the model rats. Transmission electron microscopy (TEM) showed that Shenfu injection effectively restored the mitochondrial morphological structure. The results of metabolomics showed that the metabolic phenotypes of myocardial samples presented markedly differences between groups. Nine differential metabolites could be significantly reversed in the Shenfu injection group, involving three metabolic pathways: pyruvate metabolism, histidine metabolism, and citric acid cycle (TCA cycle). The results of ROC analysis showed that the area under the curve (AUC) values of all metabolites were between 0.75 and 1.0, indicating that the differential metabolites had high diagnostic accuracy for myocardial injury, and the changes in their expression levels could be used as potential markers for efficacy evaluation. ConclusionShenfu injection significantly alleviated the damage of cardiac function, myocardium, and mitochondrial structure in the rat model of chronic heart failure with heart-Yang deficiency syndrome by ameliorating energy metabolism remodeling. Reinforcing Qi and warming Yang is a key method for treating chronic heart failure with heart-Yang deficiency syndrome.

Definitive chemoradiotherapy (dCRT) has become a cornerstone in the treatment of locally advanced esophageal cancer; however, local control remains suboptimal, and persistent lesions or locoregional recurrences after treatment are not uncommon. For patients without distant metastases but with local failure, whether surgical intervention can still offer curative potential remains a major clinical dilemma. Salvage esophagectomy (SE) offers potential long-term survival for selected patients, but this procedure is performed in the context of severe fibrosis, impaired local blood supply, and obscured anatomical planes following chemoradiotherapy, resulting in significantly higher perioperative risk compared to primary esophagectomy. Consequently, controversies exist regarding patient selection, preoperative restaging, choice of surgical approach, extent of lymphadenectomy, gastrointestinal reconstruction, and perioperative management. In recent years, with the refinement of restaging modalities such as PET/CT, the accumulation of experience in high-volume centers, and emerging evidence from clinical studies, the clinical role of SE has gradually shifted from a "high-risk salvage measure" to a "selective curative strategy aimed at achieving long-term survival in carefully selected patients". Nevertheless, standardized guidelines for patient selection, technical approaches, and perioperative management are still lacking. Based on current evidence and clinical experience, experts organized by the Integrated Esophageal Cancer Committee of Chinese Anti-Cancer Association systematically reviewed key issues regarding SE, including its definition, indications, preoperative evaluation, choice of surgical approach, lymphadenectomy, gastrointestinal reconstruction, and perioperative management, and formulated a Chinese expert consensus. This consensus aims to provide guidance for standardized assessment, appropriate referral, individualized surgical decision-making, and optimized perioperative management of patients with locoregional failure after dCRT. Ultimately, this will increase the likelihood of R0 resection, reduce the risk of severe complications, and promote the safer, more judicious, and standardized implementation of SE in high-risk scenarios.

Chinese Journal of School Health 2026;47(7):962-965
Objective:
To explore the relationship between life skills, psychological resilience and subjective well-being among primary and secondary school students, so as to provide evidence for targeted adolescent mental health education.
Methods:
From September to November, 2025, a total of 5 831 primary and secondary school students from five cities (Beijing, Guangzhou, Shenzhen, Chongqing, Urumqi) were selected by convenience sampling. The Adolescent Subjective Well being Scale, School based Adolescents Life Skills Scale, and Adolescent Psychological Resilience Scale were used for investigation. Data were analyzed using t-tests, one way ANOVA, and linear regression.
Results:
The total mean score of students subjective well being was (5.46± 0.91) ; the total mean score of life skills was (3.69±0.64); the total mean score of psychological resilience was (3.66±0.69). Statistically significant differences in subjective well being scores were found among students grouped by gender, grade, school stage, residential city, living with parents or living with siblings ( t/F =4.14, 53.92, 14.53, 49.99, 13.49, 2.18, all P <0.01). Stratified regression analyses were performed by gender (adjusting for school stage, residential city and living arrangement) and by school stage (adjusting for gender, residential city and living arrangement), the regression results indicated that life skills of boys, girls, primary school students and junior high school students( β =0.54, 0.53, 0.50, 0.57) and their psychological resilience ( β = 0.56 , 0.60, 0.56, 0.60) were positively associated with subjective well being (all P <0.01).
Conclusions
Life skills and psychological resilience may be important protective factors for subjective well being among primary and secondary school students. School based mental health education should emphasize life skills training and resilience building to promote students subjective well being.

ObjectiveTo investigate the mechanism by which Xianglian Huazhuo prescription (XLHZ) ameliorates chronic atrophic gastritis (CAG) through regulating glycolysis via the microRNA-34b-5p (miR-34b-5p)/6-phosphofructo-2-kinase/fructose-2,6-bisphosphatase 1 (PFKFB1) signaling pathway. MethodsBioinformatic screening was performed to identify the target genes of miR-34b-5p. In the animal experiments, a mouse model of CAG was established through a combination of N-methyl-N′-nitro-N-nitrosoguanidine (MNNG), ranitidine, and irregular feeding. The mice were randomized into the following groups: normal, model, Morodan group (2 g·kg-1), and high-, medium-, and low-dose XLHZ groups(7.2,3.8,1.9 g·kg-1). In the cell experiments, GES-1 cells were treated with MNNG for the modeling of CAG and grouped as follows: GES-1, MNNG+GES-1, MNNG+GES-1+XLHZ(10%), MNNG+GES-1+miR-34b-5p mimics, MNNG+GES-1+miR-34b-5p inhibitor, MNNG+GES-1+PFKFB1 inhibitor, and MNNG+GES-1+PFKFB1 mimics+XLHZ(10%). The general conditions of mice were observed. Real-time PCR was adopted to measure the expression levels of miRNA-34b-5p and PFKFB1 mRNA in the gastric mucosa of mice in each group. Dual luciferase reporter gene was used to verify the targeting interaction between miR-34b-5p and PFKFB1 in GES-1 cells exposed to MNNG. The cell-counting kit-8 (CCK-8) was used to screen the drug-containing serum concentration. Real-time PCR was employed to verify the transfection efficiency. Fluorescent probes were used to detect the expression and nuclear translocation of hypoxia-inducible factor-1α (HIF-1α) in each group of cells. The protein levels of HIF-1α, hexokinase 2 (HK2), PFKFB1, phosphofructokinase 1 (PFK1), and lactate dehydrogenase (LDHA) in the gastric mucosa of mice were determined by Western blot. The levels of glucose consumption and lactate in the serum and cells were measured by biochemical methods. Enzyme-linked immunosorbent assay (ELISA) was adopted to measure the content of adenosine triphosphate (ATP) in the gastric mucosa tissue and cells. ResultsThe animal experiments showed that compared with the normal group, the model group exhibited symptoms including mental fatigue, lethargy, sparse and dull fur, a tendency to curl up, sluggish responses, reduced food and water intake, and slow body weight gain. In addition, the model group showed decreased expression of miRNA-34b-5p (P<0.01), increased mRNA level of PFKFB1 (P<0.01), upregulated protein levels of HIF-1α, HK2, PFKFB1, PFK1, and LDHA (P<0.01), and increased glucose consumption, lactate content, and ATP content (P<0.01). Compared with the model group, the XLHZ group and Morodan group showed improved mental state, gradually improved fur, increased activity, food and water intake, and body weight. HE showed that each treatment group exhibited well arranged and increased gastric mucosal glands, reduced inflammatory cells, and recovered gastric pits. Transmission electron microscopy showed that the size of mitochondria in each treatment group returned to normal, with no obvious irregular shape, complete and clear cristae, and uniform matrix. Furthermore, each treatment group showed increased expression of miRNA-34b-5p (P<0.05), reduced mRNA level of PFKFB1 (P<0.05), downregulated protein levels of HIF-1α, HK2, PFKFB1, PFK1, and LDHA (P<0.05), and decreased glucose consumption, lactic acid, and ATP (P<0.05). The cell experiments showed that the expression and nuclear translocation of HIF-1α were reduced in all groups after treatment (P<0.05). The cell transfection efficiency was satisfactory (P<0.05). miR-34b-5p exhibited an effect comparable to that of XLHZ, effectively inhibiting glycolysis, whereas PFKFB1 promoted glycolysis and reversed the protective effect of XLHZ in CAG mice (P<0.05). ConclusionXLHZ could regulate the miR-34b-5p/PFKFB1 axis to inhibit glycolysis, thereby ameliorating MNNG-induced gastric mucosal atrophy.

Chinese Journal of School Health 2026;47(9):1229-1233
Objective:
To explore the association between parental subjective well-being and subjective well-being among primary and secondary school students, so as to provide evidence for promoting adolescent mental health from a family perspective.
Methods:
From September to November 2025, a convenience sampling method was used to recruit 4 612 students in grades 4-8 from 12 primary and secondary schools in five cities—Beijing, Guangzhou, Shenzhen, Chongqing, and Urumqi—along with their parents. Students completed the Adolescent Well being Survey Questionnaire, while parents completed the Parental Well being Survey Questionnaire. Data were analyzed using t-test, one way analysis of variance, multiple linear regression, Logistic regression, and stratified subgroup analyses.
Results:
The maximum score of the subjective well-being scale for primary and secondary school students was 301, with a total score of (224.07±46.63), representing 74.4% of the full score; the maximum score of the parental subjective well-being scale was 120, with a total score of (92.35±15.10), representing 77.0%. Multiple linear regression analysis showed that parental subjective well-being was positively associated with students overall subjective well-being, positive affect, and satisfaction in each domain (friendship, family, school, environment, freedom, and academics), and negatively associated with negative affect ( β =0.45, 0.08, 0.06, 0.07, 0.05, 0.04, 0.05, 0.04, -0.05, all P <0.01). Logistic regression and stratified analysis showed that parental subjective well-being was positively associated with students high subjective well-being ( OR =1.03), and the association existed in subgroups of different gender, grade and family structure ( OR =1.02-1.04) (all P <0.05).
Conclusions
Parental subjective well-being is positively associated with students subjective well-being. Future interventions should incorporate an integrated strategy featuring family-school collaboration to promote adolescent well-being.

Objective Jejunal interposition is an important option for restoring gastrointestinal continuity in patients with complex esophageal cancer in whom the stomach is unavailable for reconstruction due to previous gastrectomy, tumor involvement, failed gastric conduit, or other constraints. Although the jejunum offers a caliber similar to the esophagus, a rich blood supply, and preserved peristaltic function, anatomical variations in mesenteric length and vascular arcades render long-segment and high-level reconstruction susceptible to excessive tension, mesenteric torsion, venous congestion, and inadequate distal perfusion. This consensus aims to provide standardized recommendations for the application of jejunal interposition in this specific patient population. Methods This consensus was developed in accordance with the WHO Handbook for Guideline Development and Chinese national guideline development standards, with reference to the Appraisal of Guidelines for Research & Evaluation Ⅱ(AGREE Ⅱ), Reporting Items for Practice Guidelines in Healthcare (RIGHT), and Scientific, Transparent and Applicable Rankings (STAR) checklists. The project was registered on the international practice guidelines registry platform (PREPARE-2026CN1384). The working group systematically searched Chinese and English evidence addressing 12 clinical questions. Evidence was graded using the Oxford Centre for Evidence-Based Medicine (OCEBM) 2009 system, with structured appraisal of risk of bias, inconsistency, indirectness, and imprecision. Recommendations were formulated through two rounds of Delphi surveys and a face-to-face consensus meeting, with an agreement threshold of ≥75%. Results The consensus generated 12 recommendations covering indications, selection between jejunum and colon, preoperative assessment, surgical approach and reconstruction route, pedicled jejunal interposition (PJI), supercharged pedicled jejunal interposition (SPJ), indocyanine green (ICG) perfusion assessment, perioperative nutrition, management of anastomotic leakage, long-term follow-up, and special treatment scenarios. Given that the available direct evidence is predominantly derived from single-center retrospective cohorts and case series, recommendations extrapolated from general esophagectomy or other gastrointestinal surgical evidence are deliberately phrased with caution. Conclusion Jejunal interposition is a safe and effective approach for digestive tract reconstruction in patients with complex esophageal cancer in whom the stomach is unavailable. This consensus emphasizes that clinical decision-making should be individualized based on the patient's prior treatment history, reconstruction height, vascular anatomy, technical availability, and institutional experience in the Chinese context.

Breast cancer is a kind of malignant tumor with a complex mechanism, and its morbidity and mortality are increasing year by year, which seriously threatens women's health. At present, the main clinical treatments are surgical resection, radiotherapy, chemotherapy, and drug therapy, but they are often accompanied by side effects and adverse reactions, which affect the therapeutic effect. Traditional Chinese medicine (TCM) has the advantages of multi-component and multi-target treatment in the fight against breast cancer. The wnt/β-catenin signaling pathway is one of the classic pathways in cancer research. Abnormally activated Wnt/β-catenin signaling pathway inhibits β-catenin degradation by blocking the formation of Axin/glycogen synthase kinase 3β/adenomatous polyposis coli complex, thus promoting β-catenin nuclear metastasis, and it binds to T cell transcription factor/lymphoenhancer factor-1 to initiate downstream target genes and further interfere with the proliferation, migration, and invasion of tumor cells to affect the tumor process. Previous studies have shown that TCM monomers and compounds can mediate the Wnt/β-catenin signaling pathway to inhibit the malignant phenotype of breast cancer cells, thus playing an anti-breast cancer role, and the biochemical process involved in the regulation of therapeutic drugs has not been systematically combed. By analyzing and collating Chinese and foreign literature at the present stage, this paper discussed the association mechanism between Wnt/β-catenin signaling pathway and breast cancer and analyzed the internal mechanism of TCM monomers and compounds in mediating Wnt/β-catenin signaling pathway to exert anti-breast cancer effect. The statistical results showed that the flavonoids, alkaloids, and terpenoids in TCM monomers could target the Wnt/β-catenin signaling pathway and block the further development of malignant phenotype of breast cancer cells. TCM compounds with functions of clearing heat and detoxifying, promoting blood circulation and removing blood stasis, and tonifying kidney and liver were commonly used to intervene in the Wnt/β-catenin signaling pathway to prevent breast cancer. Compared with the current inhibitors of Wnt/β-catenin signaling pathway, the application of TCM monomers and compounds is expected to bring low-toxicity and high-efficiency breast cancer treatment drugs to the clinical practice, and the existing results provide a reference for the subsequent screening, research, and development of TCM small-molecule compounds and TCM compounds against breast cancer.

To clarify the species, pathogenicity, and distribution of the pathogens causing the root rot of Atractylodes lancea in Hubei province, the tissue separation method was used to isolate the pathogens from root rot samples in the main planting areas of A. lancea in Hubei. Based on the preliminary identification of the Fusarium genus by the internal transcribed spacer(ITS) sequence, three housekeeping genes, EF1/EF2, Btu-F-FO1/Btu-F-RO1, and FF1/FR1, were amplified and sequenced. Subsequently, a phylogenetic tree was constructed based on these TEF gene sequences to classify the pathogens. The pathogenicity of these strains was determined using the root irrigation method. A total of 194 pathogen strains were isolated using the tissue separation method. Molecular identification using the three housekeeping genes identified the pathogens as F. solani, F. oxysporum, F. commune, F. equiseti, F. tricinctum, F. redolens, F. fujikuroi, F. avenaceum, F. acuminatum, and F. incarnatum. Among them, F. solani and F. oxysporum were the dominant strains, widely distributed in multiple regions, with F. solani accounting for approximately 54% of the total isolated strains and F. oxysporum accounting for approximately 34%. Other strains accounted for a relatively small proportion, totaling approximately 12%. The results of pathogenicity determination showed that there were certain differences in pathogenicity among strains. The analysis of the pathogenicity differentiation of the widely distributed F. solani and F. oxysporum strains revealed that these dominant strains in Hubei were mainly highly pathogenic. This study determined the species, pathogenicity, and distribution of the pathogens causing the root rot of A. lancea in Hubei province. The results provide a scientific basis for further understanding the root rot of A. lancea and its epidemic occurrence and scientifically preventing and controlling this disease.

ObjectiveTo explore the effect of modified Lianpoyin formula (LPYJWF) in the treatment of Helicobacter pylori (Hp)-associated gastric mucosal damage based on mitochondrial autophagy and NLRP3 inflammasome signaling pathway. MethodsA total of 60 eight-week-old Balb/c male mice were assigned via the random number table method into control, model, high-dose LPYJWF (LPYJWF-H, 27.3 g·kg-1·d-1), medium-dose LPYJWF (LPYJWF-M, 13.65 g·kg-1·d-1), low-dose LPYJWF (LPYJWF-L, 6.83 g·kg-1·d-1), and quadruple therapy groups. Except the control group, other groups were modeled for Hp infection. Mice were administrated with LPYJWF at corresponding doses by gavage. Quadruple therapy group was given omeprazole (6.06 mg·kg-1·d-1) + amoxicillin (303 mg·kg-1·d-1) + clarithromycin (151.67 mg·kg-1·d-1) + colloidal pectin capsules (30.3 mg·kg-1·d-1) by gavage. The control group was given an equal volume of 0.9% NaCl for 14 days. Hematoxylin-eosin (HE) staining was used to observe the pathological changes of gastric mucosa, and Warthin-Starry (W-S) silver staining was used to detect Hp colonization. Transmission electron microscopy was employed to observe the mitochondrial ultrastructure of the gastric tissue, and immunofluorescence co-localization assay was adopted to detect the expression of mitochondrial transcription factor A (TFAM) and translocase of the outer mitochondrial membrane member 20 (TOMM20). The water-soluble tetrazolium salt method and thiobarbituric acid method were used to determine the levels of superoxide dismutase (SOD) and malondialdehyde (MDA), respectively, in the gastric tissue. Western blot was employed to measure the protein levels of PTEN-induced kinase 1 (PINK1), Parkin, p62, microtubule-associated protein 1 light chain 3 (LC3), NOD-like receptor protein 3 (NLRP3), apoptosis-associated speck-like protein containing a CARD (ASC), interleukin-1β (IL-1β), and interleukin-18 (IL-18). Real-time quantitative PCR was employed to assess the mRNA levels of PINK1, Parkin, p62, and LC3. ResultsCompared with the control group, the model group presented obvious gastric mucosal damage, colonization of a large number of Hp, severe mitochondrial damage, vacuolated structures due to excessive autophagy, reduced TOMM20 and TFAM co-expression in the gastric mucosal tissue, and reduced SOD and increased MDA (P<0.01). In addition, the gastric tissue in the model group showed up-regulated protein and mRNA levels of PINK1, Parkin, and LC3 and down-regulated protein and mRNA levels of p62 (P<0.01, as well as increased expression of inflammasome-associated proteins NLRP3, ASC, IL-1β, and IL-18 (P<0.01). Compared with the model group, the LPYJWF and quadruple therapy groups showed alleviated pathological damage of gastric mucosa, reduced Hp colonization, mitigated mitochondrial damage, and increased co-expression of TOMM20 and TFAM. The SOD level was elevated in the LPYJWF-L group (P<0.01), and the MDA levels became lowered in the LPYJWF and quadruple therapy groups (P<0.05, P<0.01). Furthermore, the LPYJWF and quadruple therapy groups showed down-regulated mRNA levels of PINK1, Parkin, and LC3 and protein levels of PINK1 and Parkin, and up-regulated mRNA level of p62 (P<0.01). The LPYJWF-M, LPYJWF-H, and quadruple therapy groups showcased down-regulated LC3 Ⅱ/LC3 Ⅰ level (P<0.05, P<0.01) and up-regulated protein level of p62 (P<0.01). The expression of inflammasome-associated proteins NLRP3, ASC, IL-1β, and IL-18 were reduced in the LPYJWF and quadruple therapy groups (P<0.05, P<0.01). ConclusionLPYJWF ameliorates gastric mucosal damage and exerts mucosa-protective effects in Hp-infected mice, which may be related to the inhibition of excessive mitochondrial autophagy, thereby inhibiting the activation of the NLRP3 inflammasome pathway.
