The Guidelines for Construction of Traditional Chinese Medicine Pharmacovigilance Systems in Medical Institutions (T/CACM 1563.2-2024) were the first special guideline in China to systematically assist medical institutions in establishing a pharmacovigilance system tailored to the characteristics of traditional Chinese medicine (TCM). This guideline was jointly developed with 23 authoritative medical and research institutions in China, under the lead of the Institute of Basic Clinical Medicine, China Academy of Chinese Medical Sciences. The purpose of this guideline was to standardize pharmacovigilance work throughout the entire lifecycle of TCM (including research and development, marketing, and application) and to establish a four-dimensional framework of "organizational structure, institutional system, information platform, and vigilance activities". Key components included the establishment of a TCM Safety Committee, the construction of nine core systems, the development of an information platform that complies with International Council for Harmonization of Technical Requirements for Pharmaceuticals for Human Use (ICH) E2B standards, alongside the risk monitoring, identification, assessment, and control during clinical trials and post-marketing phases. Therefore, this guideline filled a significant gap in the systemic standards for TCM safety management within medical institutions. Strictly adhering to domestic and international laws and regulations, the guideline compilation involved multiple rounds of expert interviews, systematic evidence integration, and broad consensus. This guideline was specified to be applicable to medical institutions at all levels, primarily addressing core issues, including the difficulty in adverse reaction identification, low reporting rates, and incomplete risk management chains due to the complex composition and diverse application of TCM. The compilation process was scientific and rigorous, ensuring alignment with current national laws and regulations, and was registered internationally. In the future, implementation will be promoted through standardized training, tiered dissemination, as well as a post-effect evaluation and dynamic revision mechanism starting two years after publication. All these aimed to enhance medical institutions' proactive capabilities in preventing and controlling TCM safety risks, ensure patient medication safety, and promote the high-quality development of TCM.

To standardize the clinical application of oral Chinese patent medicines (CPMs), and address the safety issues arising from their dosage form characteristics, irrational clinical use, and the lack of targeted pharmacovigilance systems, the China Association of Chinese Medicine organized the formulation and release of Pharmacovigilance Guidelines for Clinical Application of Oral Chinese Patent Medicines, aiming to inform the safe clinical use of oral CPMs and related pharmacovigilance work. According to the principles of GB/T1.1—2020 and the Drug Administration Law of the People's Republic of China (2019 revision), the Institute of Basic Research in Clinical Medicine, China Academy of Chinese Medical Sciences, led a drafting group comprising 18 institutions. After multiple rounds of expert interviews, literature retrieval, evidence screening, and extensive solicitation of opinions, the Guidelines were registered internationally. Systematic standardization focused on safety monitoring, risk identification, assessment, control, and other aspects. The Guidelines clarified the characteristics of oral CPMs in terms of safety monitoring, known risks, and potential risks, compared to non-oral CPMs. Then, risk control measures were proposed, including medication in special populations and irrational medication. As a special guideline for pharmacovigilance in the clinical application of oral CPMs, the Guidelines systematically construct a technical system in line with the characteristics of traditional Chinese medicine (TCM), which is essential for improving the clinical safety management of oral CPMs and provides an important reference for medical institutions, pharmaceutical manufacturers, and regulatory authorities.

5.Analysis of undernutrition and associated factors among left behind and nonleftbehind primary and secondary school students in the Nutrition Improvement Program areas in central and western China
Chinese Journal of School Health 2026;47(3):327-331
Objective:
To investigate the prevalence of undernutrition and its associated factors among left behind and non left behind primary and secondary school students in the Nutrition Improvement Program for Rural Compulsory Education Students (NIPRCES) areas of central and western China, so as to provide evidence for improving the nutritional status of children and adolescents.
Methods:
A survey was conducted among 123 782 students selected by random cluster sampling method in grades 3-9 from NIPRCES in central (Hebei, Shanxi, Heilongjiang, Jilin, Anhui, Jiangxi, Henan, Hunan, Hubei, and Hainan) and western (Gansu, Guangxi, Inner Mongolia, Ningxia, Tibet, Shaanxi, Guizhou, Sichuan, Xinjiang, the Xinjiang Production and Construction Corps, Yunnan, Qinghai, and Chongqing) China in 2023. Anthropometric measurements and questionnaires were used to assess nutritional and dietary status. The prevalence of undernutrition was compared between left behind and non left behind students by Chi square test, and associated factors were analyzed by three level Logistic mixed effects model.
Results:
The prevalence of undernutrition was 8.5% (4 326) in left behind students and 8.1% (5 905) in non left behind students. Three level Logistic mixed effect model analysis showed that whether left behind or non left behind, the undernutrition rates of primary and secondary students in western regions were higher than those of students in central regions [ OR (95% CI )=1.72(1.57-1.87),2.25(2.07- 2.43 )]; the undernutrition risk was lower for those whose fathers had a cultural level of high school or above [ OR (95% CI )=0.69(0.62-0.77),0.90(0.82-0.98)] or junior high school [ OR (95% CI )=0.72(0.66-0.79),0.92(0.85-0.99)] compared to those with primary school or below; picky eating or selective eating increased the risk of undernutrition [ OR (95% CI )=2.36(2.07-2.68),2.28(2.04-2.55)], and primary and secondary school students without nutritional content in health education classes had higher rates of undernutrition [ OR (95% CI )=1.12(1.03-1.23),1.09(1.01-1.17)](all P <0.05).
Conclusion
The prevalence of undernutrition is slightly higher in left behind primary and secondary students than in non left behind primary and secondary students in central and western NIPRCES areas, with variations across different characteristics.

Elderly patients with primary membranous nephropathy (PMN) exhibit significant prognostic heterogeneity and poor tolerance to immunotherapy. However, there is a lack of early prognostic prediction tools specifically for this population. This study aimed to develop a prognostic prediction model applicable to elderly PMN patients. This study retrospectively included elderly patients with PMN confirmed by renal biopsy. The primary endpoint was a adverse composite outcome including end-stage renal disease (ESRD), a ≥50% decline in estimated glomerular filtration rate (eGFR), or all-cause death. Patients were randomly divided into a training cohort and a validation cohort at a ratio of 7∶3. Key prognostic features were identified using least absolute shrinkage and selection operator (LASSO) regression combined with random survival forest, and a predictive model was constructed based on penalized Cox regression. Model performance was evaluated using the concordance index (C-index), time-dependent area under the receiver operating characteristic curve (AUROC), calibration curves, and decision curve analysis. The SurvSHAP (t) method was employed for interpretability analysis of the model. A total of 309 elderly patients with PMN were included in this study, with a median age of 65.00 years (IQR, 62.00-68.00) and a male predominance 61.2%(189/309).During a median follow-up of 47.00 months (IQR, 25.00-89.00), 38.2%(118/309) reached the endpoint event. The final model included nine key features, including eGFR, total protein (TP), glomerular capsular adhesion, urine glucose, segmental glomerulosclerosis proportion, fibrinogen, urea, age, and activated partial thromboplastin time (APTT). In the validation cohort, the model demonstrated good discrimination, with a C-index of 0.731(95% CI: 0.652-0.797). The time-dependent AUROCs for predicting adverse outcomes at 3, 5, and 10 years were 0.758(95% CI: 0.614-0.901), 0.781(95% CI: 0.646-0.916), and 0.866(95% CI: 0.740-0.993), respectively. Calibration curves demonstrated a high degree of concordance between predicted probabilities and actual event rates. Decision curve analysis confirmed the net clinical benefit of the model.SurvSHAP (t) analysis showed that eGFR, TP, glomerular capsular adhesion, urine glucose, and the proportion of segmental glomerular sclerosis were the top five variables contributing to the model. This prognostic model effectively predicts the risk of adverse outcomes in elderly patients with PMN in the internal validation cohort, offering a potential scientific basis for individualized risk stratification and treatment decision-making in this population.

Infection-related glomerulonephritis (IRGN) is an immune-mediated glomerular injury triggered by infectious agents. This article reports a case of immune complex-mediated glomerulonephritis following acute hepatitis B virus infection, which continued to progress despite standard antiviral and immunosuppressive therapy. Given the significant elevation of soluble complement membrane attack complex (sC5b-9), an indicator of terminal complement pathway activation, the patient was treated with eculizumab. Following treatment, the patient's urine protein-to-creatinine ratio significantly decreased, hypoalbuminemia and hematuria markedly improved, and sC5b-9 levels declined. This case suggests that abnormal complement system activation may be a key mechanism driving disease persistence in some patients with IRGN. For those unresponsive to conventional therapy, complement function screening and targeted terminal complement pathway inhibition may represent an effective salvage strategy.

OBJECTIVE To construct a preoperative medication reconciliation model assisted by a localized large language model (LLM) for gastric cancer and evaluate its clinical efficacy. METHODS A total of 249 gastric cancer patients with a history of continuous medication before admission in the Gastric Surgery Department of Jiangsu Cancer Hospital were retrospectively enrolled. Patients were divided into training set (154 cases) and validation set (95 cases) based on the order of time. Based on guidelines, drug package inserts, and other evidence, a standardized medication reconcili ation process and a structured knowledge base were constructed. DeepSeek-V3 LLM was deployed privately in the hospital, combined with retrieval-augmented generation technology, to achieve automated integration of medication information, risk screening, and generation of personalized recommendations. The quality of LLM-generated recommendations was evaluated using automatic metrics (BERT Score and ROUGE-1, 2, L) and manual scoring [seven-dimensional index (7DI) ] . Spearman correlation analysis was performed to explore the correlation between automatic scores and manual scores. Cronbach’s α coefficient was used to test the internal consistency of manual scoring results. The time consumed by manual and LLM-assisted medication reconciliation was compared across tasks of different difficulty levels (simple, moderate, and high). RESULTS A structured knowledge base covering 8 major drug categories was finally established, covering common and high-risk preoperative medication scenarios and providing structured retrieval support for the LLM. For automatic evaluation, the precision, recall, and F1-score of BERT Score were 0.783±0.033, 0.811±0.038, and 0.796±0.028, respectively. The F1-scores of ROUGE-1, ROUGE-2 and ROUGE-L were 0.566±0.067, 0.338±0.076 and 0.468±0.082, respectively. The 7DI scores from three manual raters ranged from 32.06 to 33.45. The F1-score of automatic scoring was significantly positively correlated with the 7DI score of manual scoring (maximum coefficient of determination=0.611, P <0.001), and the internal consistency of manual scoring was good (Cronbach’s α = 0.876). In terms of efficiency, LLM-assisted medication reconciliation reduced time consumption by more than 90% compared with manual reconciliation in the simple, moderate, and high-difficulty groups ( P <0.001). CONCLUSIONS The medication reconciliation model constructed based on a localized LLM and structured knowledge base shows high accuracy, consistency, and clinical applicability in complex preoperative medication scenarios for gastric cancer. It can improve the efficiency of medication reconciliation and reduce potential medication risks.

ObjectiveTo investigate whether Huanglian Jiedutang (HLJD) and its major active constituents (geniposide, baicalin, and berberine) can inhibit the inflammatory response of BV2 cells under lipopolysaccharide (LPS) stimulation via the high-mobility group protein B1 (HMGB1)/Toll-like receptor 4 (TLR4)/nuclear factor-κB (NF-κB) signaling pathway, and to explore differences in therapeutic efficacy among the three monomers, their combined formula, and HLJD under equal content ratios. MethodsBV2 microglial cells were used as the primary experimental model. Cell viability was assessed using the cell counting kit-8 (CCK-8) method to examine the effects of different concentrations of dimethyl sulfoxide (DMSO, 0.8%, 0.4%, 0.2%, 0.1%, and 0.05%) on cell viability. IncuCyte was employed to monitor the growth of cells under different concentrations of HLJD (200, 100, 50, 25, 12.5, 6.25 mg·L-1). Nitric oxide (NO) assay was used to screen the optimal HLJD concentration. High-performance liquid chromatography (HPLC) determined the content of geniposide, baicalin, and berberine in HLJD, and experimental groups were subsequently established according to the relative proportions of these constituents. CCK-8 assay evaluated cell viability under different treatments. Enzyme-linked immunosorbent assay (ELISA) measured levels of inflammatory factors (TNF-α, IL-1β, IL-6, IL-10) in the supernatant. Flow cytometry assessed the effects of treatments on M1-type polarization of BV2 cells. Western blot determined the expression levels of HMGB1, TLR4, and NF-κB-related proteins. ResultsCompared with the blank group, DMSO at concentrations ≤0.2% did not affect cell viability within 48 h. BV2 cell growth plateaued at 24 h after treatment with 200 mg·L-1 HLJD. Under stimulation with 2 mg·L-1 LPS, this concentration of HLJD effectively reduced NO release, and 6 h pre-treatment had a stronger inhibitory effect on NO than direct administration. HPLC results showed that 1 mg of HLJD freeze-dried powder contained approximately 24 μg of geniposide, 15 μg of baicalin, and 30 μg of berberine. Based on these ratios, experimental groups were blank, LPS (2 mg·L-1), HLJD (200 mg·L-1), monomer combination, geniposide (4.8 mg·L-1), baicalin (3 mg·L-1), and berberine (6 mg·L-1). The monomer combination group consisted of all three active constituents dissolved together. LPS and HLJD or its active constituents did not affect cell viability compared with the blank group. LPS significantly increased TNF-α, IL-1β, IL-6, and IL-10 in the supernatant (P<0.01). HLJD and its active constituents significantly reduced pro-inflammatory factors TNF-α, IL-1β, and IL-6 (P<0.05, P<0.01) while upregulating anti-inflammatory IL-10 (P<0.01), with the monomer combination showing the strongest effect (P<0.05, P<0.01). Compared with the blank group, LPS significantly increased the proportion of CD80⁺CD86⁺ (M1-type) BV2 cells (P<0.01). HLJD and its constituents partially inhibited M1 polarization (P<0.05, P<0.01), with the monomer combination exhibiting the most pronounced effect (P<0.05, P<0.01). Compared with the blank group, LPS upregulated HMGB1, TLR4, and NF-κB-related proteins (P<0.01), whereas HLJD and its active constituents significantly reduced their expression (P<0.05, P<0.01), with the monomer combination having the strongest regulatory effect (P<0.05, P<0.01). ConclusionHLJD and its major active constituents (geniposide, baicalin, berberine) can inhibit LPS-induced inflammatory responses in BV2 cells. The combination of the three active constituents demonstrates the most potent anti-inflammatory effect, significantly attenuating M1-type polarization of BV2 cells via the HMGB1/TLR4/NF-κB signaling pathway.

OBJECTIVE To study the mechanism of Xinnao shutong capsule alleviating cerebral ischemia reperfusion injury (CIRI) in rats by regulating the ferroptosis pathway. METHODS SD rats were randomly divided into sham operation group, model group, Xinnao shutong low-dose, high-dose group (220, 440 mg/kg), Ginkgo biloba leaves extract group (positive control, 150 mg/kg). Each group of rats was orally administered with the corresponding medication/normal saline for 7 consecutive days. Transient occlusion of the middle cerebral artery was adopted to induce the CIRI model; the samples were taken 24 h after the operation; the cerebral infarction area of rats was detected, and the cerebral infarction rate was calculated. The pathological changes of brain tissues were observed, and the levels of lipid peroxide (LPO), malondialdehyde (MDA) and glutathione (GSH) in cerebral tissue were detected; mRNA and protein expressions of nuclear factor-erythroid 2-related factor 2 (Nrf2), heme oxygenase 1(HO-1) and glutathione peroxidase 4 (GPX4) were all detected in cerebral tissue of rats. RESULTS Compared with model group, the cerebral infarction rate, the content of total iron in cerebral tissue and serum level of LPO (except for Ginkgo biloba leaves extract group and Xinnao shutong low-dose group) were all decreased significantly in G. biloba leaves extract group and Xinnao shutong groups (P<0.05 or P<0.01); the serum level of GSH, the protein and mRNA expressions of Nrf2, HO-1 and GPX4 were all increased significantly (P<0.05 or P<0.01). The pathological damage to brain tissue was reduced, the number of nerve cells increased, the edema was alleviated, and the nuclear membrane was flattened. CONCLUSIONS Xinnao shutong capsule can inhibit ferroptosis and reduce CIRI, the mechanism of which may be associated with the activation of the Nrf2/HO-1/GPX4 signaling pathway.
