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.

OBJECTIVE To focus on the classic NOD-like receptor protein 3 (NLRP3)/Caspase-1/gasdermin D (GSDMD) pyroptosis pathway and explore the mechanism by which Huatan qushi huoxue formula (HQHF) inhibits macrophage pyroptosis to ameliorate metabolic dysfunction-associated steatohepatitis (MASH). METHODS RAW264.7 cells were divided into 5 groups: Control group (10% blank serum), Model group [10% blank serum+5 μg/mL lipopolysaccharide (LPS)], HQHF-L group (2.5% drug-containing serum+7.5% blank serum+5 μg/mL LPS), HQHF-M group (5% drug-containing serum+5% blank serum+5 μg/mL LPS), and HQHF-H group (10% drug-containing serum+5 μg/mL LPS). After 24 h of routine culture post-administration, cells and supernatants were collected for assays. Cell morphology was observed via scanning electron microscopy and phase-contrast microscopy; localization and expression of gasdermin D-N (GSDMD-N) were observed by immunofluorescence. Interleukin-1β (IL-1β) and IL-18 contents in supernatants were detected by ELISA; mRNA and protein expressions of NLRP3, Caspase-1, and GSDMD were measured using real-time PCR and Western blot. RESULTS Compared with the Control group, the Model group showed typical pyroptotic morphology (cell membrane bulging and pore formation), increased aggregation and fluorescence intensity of GSDMD-N on the cell membrane ( P <0.05), significantly increased the contents of IL-1β and IL-18 in cell supernatants ( P <0.05), and significantly up-regulated mRNA and protein expressions of NLRP3, Caspase-1, and GSDMD in cells ( P <0.05). Compared with the Model group, the HQHF-L, HQHF-M and HQHF-H groups showed improved pyroptotic morphology, reduced membrane localization and significantly weakened fluorescence intensity of GSDMD-N ( P <0.05), significantly decreased the contents of IL-1β and IL-18 in cell supernatants ( P <0.05), and significantly down-regulated mRNA and protein expressions of NLRP3, Caspase-1, and GSDMD in cells ( P <0.05). CONCLUSIONS HQHF inhibits LPS-induced macrophage pyroptosis, and its mechanism of improving MASH may be associated with the suppression of the activation of the classical NLRP3/Caspase-1/GSDMD pyroptosis pathway.

ObjectiveTo investigate the intervention mechanism of the traditional Chinese medicine Number 2 Feibi recipe (N2FBR) in idiopathic pulmonary fibrosis (IPF), focusing on its effects on endoplasmic reticulum (ER) stress, apoptosis, stemness maintenance, and regenerative capacity of alveolar type Ⅱ epithelial cells (AT2 cells), and to validate the modern translational pathway of the theory of "deficiency of Zong Qi leading to pulmonary atelectasis and atrophy". MethodsA mouse model of pulmonary fibrosis was induced by bleomycin (BLM). Mice were randomly divided into blank control, model, low-, and high-dose N2FBR intervention groups (9.1, 18.2 g·kg-1), and prednisolone intervention group (6.5 mg·kg-1). Pulmonary histopathological changes and collagen deposition were evaluated using hematoxylin-eosin (HE) and Masson's trichrome staining. Hydroxyproline (HYP) content was measured by the alkaline hydrolysis method. Lung coefficient and pulmonary function parameters were evaluated. The mRNA expression levels of fibrosis-related factors, including collagen type Ⅰ alpha 1 chain (ColIa1), alpha-smooth muscle actin (α-SMA), and tissue inhibitor of metalloproteinase 1 (Timp1), were detected by real-time polymerase chain reaction (Real-time PCR). Cell apoptosis was assessed using the terminal deoxynucleotidyl transferase dUTP nick-end labeling (TUNEL) assay. Apoptosis of AT2 cells was further evaluated by double immunofluorescence staining for surfactant protein C (SPC) and cysteine-aspartic protease-3 (Caspase-3). Endoplasmic reticulum (ER) stress in AT2 cells was examined by double staining for SPC and protein kinase R-like endoplasmic reticulum kinase (PERK). Ultrastructural changes of ER and lamellar bodies in AT2 cells were observed by transmission electron microscopy (TEM). The expression levels of key proteins involved in ER stress and apoptosis pathways, including PERK, activating transcription factor 4 (ATF4), and Caspase-3, were detected by Western blot. Double immunofluorescence staining of SPC and Ki-67 antigen (Ki-67) was performed to evaluate the proliferative capacity of AT2 cells. Lineage tracing technology (labeling AT2 cells with GFP) combined with Krt8 labeling was used to evaluate intermediate differentiation states, and morphological transformation of AT2 cells into alveolar type Ⅰ epithelial cells (AT1) was observed. ResultsBLM-induced mice exhibited significant structural disruption of lung tissue, increased collagen deposition, elevated lung coefficient, decreased pulmonary function, and upregulation of fibrosis-related factors (P<0.01). High-dose N2FBR treatment significantly ameliorated lung tissue damage and dysfunction, significantly reduced HYP content (P<0.01), and significantly downregulated ColIa1, α-SMA, and Timp1 expression (P<0.01). Apoptosis analysis showed increased TUNEL-positive and Caspase-3-positive AT2 cells in the model group, which was significantly reduced by high-dose N2FBR treatment. TEM revealed swollen ER structures in AT2 cells of the model group, which tended to return to normal following treatment. PERK protein staining analysis showed evident ER stress in AT2 cells of the model group, which were markedly alleviated in the treatment group. The expression levels of ER stress-related proteins PERK and ATF4, as well as the apoptosis-related protein Caspase-3, were elevated in the model group and significantly reduced after treatment. TEM also revealed disrupted lamellar body structures in the model group, which tended to recover in the treatment group. Regarding the proliferative capacity of AT2 cells, the proportion of Ki-67⁺SPC⁺ AT2 cells significantly increased in the treatment group (P<0.01). Lineage tracing showed that the proportion of keratin 8-positive green fluorescent protein-positive (Krt8⁺GFP⁺) cells increased in the model group, indicating differentiation arrest. This proportion was significantly reduced in the treatment group, and the morphology of GFP⁺ cells exhibited a flattened, extended shape, suggesting restored differentiation toward AT1 cells. ConclusionN2FBR alleviates ER stress in AT2 cells, reduces AT2 cell apoptosis, restores lamellar body structure and function, enhances proliferation activity, and alleviates differentiation arrest to promote differentiation into AT1 cells, thereby repairing the alveolar epithelium and effectively blocking the progression of pulmonary fibrosis. Its traditional Chinese medicine mechanism of "replenishing Zong Qi, harmonizing Qi and blood, and unblocking pulmonary meridians" closely aligns with the modern regulatory pathway of AT2 stem cells, providing a novel theoretical basis and experimental evidence for the intervention of IPF with traditional Chinese medicine.

ObjectiveThis study aims to compare the modeling effects of submaxillary gland antigen and salivary gland antigen in the establishment of Sjögren syndrome (SS) mouse models, and to characterize the phenotypic and immunological features of these models in comparison with spontaneous SS-prone non-obese diabetic (NOD)/LtJ mice. MethodsAdult C57BL/6J mice (equal numbers of males and females) were immunized with submaxillary gland antigen or salivary gland antigen, respectively, combined with Freund's adjuvant to induce SS models. Mice immunized with phosphate-buffered saline (PBS) combined with Freund's adjuvant served as the control group. Immunization was induced via multiple subcutaneous injections in the back with antigen combined with Freund's complete adjuvant (FCA) on Days 1 and 7. A booster immunization was administered via multiple subcutaneous injections in the back with antigen combined with Freund's incomplete adjuvant (FIA) on Day 14. Female NOD/LtJ mice were used as the spontaneous SS model group, with ICR mice as the corresponding control strain for comparative analysis. Body weight, water intake, and salivary flow rate of mice were dynamically monitored for 4 weeks. At the end of the experiment, tissue and serum samples were collected, the weights of submaxillary glands, thymus, and spleen were measured, and organ indices (organ-to-body weight ratios) were calculated. Pathological morphological analysis of the submaxillary gland and spleen was performed with hematoxylin and eosin (HE) staining. Serum interleukin-17 (IL-17) level was detected using enzyme-linked immunosorbent assay (ELISA). Real-time quantitative polymerase chain reaction was used to detect the mRNA expression levels of SS type A (SSA) and SS type B (SSB) in submaxillary gland tissues. ResultsFemale mice in the submaxillary gland antigen group exhibited significantly increased water intake (P<0.05) and reduced salivary flow rate (P<0.05) compared with the female control group. No statistically significant differences were observed in the submaxillary gland index, thymus index and spleen index (P>0.05). Focal lymphocytic infiltration was observed in the submaxillary glands, and the splenic marginal zone was enlarged. Serum IL-17 levels were significantly increased (P<0.05). There was no significant difference in submaxillary gland SSA/SSB expression levels (P>0.05). Compared with the female control group, female mice in the salivary gland antigen group showed no statistically significant differences in water intake, salivary flow rate, submaxillary gland index, and spleen index (P>0.05), whereas the thymus index was significantly reduced (P<0.01). Mild inflammatory cell infiltration and glandular atrophy were observed in the submaxillary glands, and the splenic white pulp and marginal zone were slightly enlarged. Serum IL-17 levels and submaxillary gland SSB mRNA expression levels were significantly increased (P<0.01), whereas no significant change was observed in submaxillary gland SSA expression levels (P>0.05). Compared with the male control group, mild submaxillary gland atrophy was observed in male mice in the submaxillary gland antigen group, whereas no obvious changes were found in other modeling-related indicators (P>0.05). Compared with the ICR control group, NOD/LtJ model mice exhibited elevated water intake (P<0.05), significantly reduced salivary flow rate (P<0.01), no significant differences in the submaxillary gland index or spleen index (P>0.05), but a significantly increased thymus index (P<0.05). Marked focal infiltration was observed in the submaxillary glands, the splenic marginal zone was obviously enlarged, and serum IL-17 concentrations as well as submaxillary gland SSA/SSB expression levels were significantly increased (P<0.05). ConclusionSubmaxillary gland antigen and salivary gland antigen can induce SS-related features in female C57BL/6J mice. The SS-related phenotype is more pronounced in the submaxillary gland antigen group than in the salivary gland antigen group, but weaker than that in spontaneously SS-prone female NOD/LtJ mice. Immunization of male C57BL/6J mice with submaxillary or salivary gland antigens fails to induce an obvious SS phenotype.

ObjectiveTo investigate the feasibility, safety, and efficacy of surgery-assisted transjugular intrahepatic portosystemic shunt (SA-TIPS) in the treatment of portal hypertension comorbid with complex portal vein thrombosis, including cavernous transformation of the portal vein (CTPV). MethodsAn analysis was performed for the data of 36 patients with portal hypertension and complex portal vein thrombosis who underwent SA-TIPS in Beijing Shijitan Hospital, Capital Medical University, from November 2023 to January 2025, including general status, technical data of the surgical process (surgical success rate, puncture times, time of operation, the number of stents used, and the length of shunt), perioperative complications, and surgical recovery. The change in portal pressure gradient (PPG) after shunt was compared, and the rate of reaching the standard for PPG reduction was calculated, as well as stent patency rate within 1 week after surgery. The paired samples t-test was used for comparison of continuous data between two groups. ResultsAmong the 36 patients, 34 (94.4%) underwent SA-TIPS successfully. The incidence rate of perioperative complications was 16.7% (6/36), including 3 cases of thoraco-abdominal hemorrhage, 2 cases of intraoperative arrhythmia, and 1 case of incision infection. There was a significant reduction in PPG after SA-TIPS (t=19.85, P<0.01), and the patients achieving a ≥50% reduction in PPG accounted for 76.5% (26/34). Imaging reexamination within 1 week showed a shunt patency rate of 100%. ConclusionSA-TIPS has a high technical success rate, a favorable safety profile, and good efficacy in the treatment of portal hypertension comorbid with complex portal vein thrombosis (including CTPV), and therefore, it holds promise for clinical application.

Childhood simple obesity has become a significant public health issue in China. Modern medicine primarily relies on lifestyle interventions and often suffers from poor long-term compliance, while pharmacological options are limited and associated with potential adverse effects. Traditional Chinese Medicine (TCM) has a long history in the prevention and management of this condition, demonstrating eight distinct advantages, including systematic theoretical foundation, diversified therapeutic approaches, definite therapeutic efficacy, high safety profile, good patient compliance, comprehensive intervention strategies, emphasis on prevention, and stepwise treatment protocols. Additionally, TCM is characterized by six distinctive features: the use of natural medicinal substances, non-invasive external therapies, integration of medicinal dietetics, simple exercise regimens, precise syndrome differentiation, and diverse dosage forms. By combining internal and external treatments, TCM facilitates individualized regimen adjustment and holistic regulation, demonstrating remarkable effects in improving obesity-related metabolic indicators, regulating constitutional imbalance, and promoting healthy behaviors. However, challenges remain, such as inconsistent operational standards, insufficient high-quality clinical evidence, and a gap between basic research and clinical application. Future efforts should focus on accelerating the standardization of TCM diagnosis and treatment, conducting multicenter randomized controlled trials, and fostering interdisciplinary integration, so as to enhance the scientific validity and international recognition of TCM in the prevention and treatment of childhood obesity.

ObjectiveTo investigate the possible mechanism of Pibai Yucuo Formula (枇柏愈痤方, PYF) in treating acne from the perspective of skin barrier damage. MethodsThirty-two mice were randomly divided into blank group, model group, minocycline group, and PYF group, with 8 mice in each group. Except for the blank group, mice were induced by intradermal injection of Cutibacterium acnes (C.acnes) combined with topical application of artificial sebum to establish acne model. The blank group and model group received intragastric administration of 0.2 ml of distilled water, while the PYF group received intragastric administration of 22.75 g/(kg·d)of PYF, and the minocycline group received 0.013 g/(kg·d)of minocycline suspension, all once daily for 5 consecutive days. On day 0 and day 6 of the experiment, the body weight of mice in each group was recorded, and the absolute value of the body weight difference during the experiment was calculated. Skin conditions were assessed with multifunctional skin imaging system on the 2nd, 4th and 6th day of the experiment. Skin barrier function indicators including transepidermal water loss (TEWL), and the water content of the stratum corneum and epidermis on day 0, 2, 4 and 6 of the experiment. Optical coherence tomography (OCT) was used to observe stratum corneum and skin thickness on the 1st, 3rd and 5th day of the experiment. Hematoxylin-eosin (HE) staining was performed to observe histopathological changes, while ELISA was used to detect interleukin-17A (IL-17A) levels, and immunofluorescence staining was used to assess skin barrier-related proteins filaggrin (FLG) and loricrin (LOR) levels of skin lesions on day 6 of the experiment. ResultsCompared to the blank group, the model group showed a decrease in body weight on day 6, and an increase in the absolute value of the difference in body weight before and after the experiment (P<0.05). On day 4 and 6, TEWL values increased, while water content in the skin stratum corneum and epidermis decreased (P<0.05), accompanied by elevated IL-17A level and reduced immunofluorescence intensity of FLG and LOR proteins (P<0.05). The model group mice showed papules or pustules at the skin modeling site with progressively worsening desquamation under multifunctional skin imaging system. OCT revealed focal epidermal protrusions, blurred epidermal-dermal boundaries, and disorganized structural layers. HE staining showed significant epidermal hyperkeratosis and incomplete keratinization in the skin, with keratin plug formation in hair follicles and glandular lumens, thickened stratum corneum, hyperplasia of the stratum spinosum, as well as dense dermal inflammatory cell infiltration, and capillary dilation. Compared to the model group, both the minocycline group and the PYF group showed a reduced difference in body weight before and after experiment (P<0.05). On day 4 and 6, the TEWL value decreased, and water content of the skin stratum corneum increased (P<0.05); on day 6, the IL-17A level in the skin lesions decreased and immunofluorescence intensity of FLG and LOR proteins increased (P<0.05). On day 4 and 6, the severity of the skin lesions and range of redness and swelling were lighter than those in the model group, with reverted epidermal thickness, smoother surface and clearer epidermis-dermis boundary. HE staining showed that the degree of skin keratinization was reduced, and the inflammatory infiltration and vascular dilation in the dermis were improved compared to the model group. The PYF group showed better results than the minocycline group in reducing TEWL value on day 4 (P<0.05). ConclusionPYF may improve inflammation and skin barrier damage by downregulating IL-17A levels in lesion tissue and increasing skin barrier-related proteins, which could be one of the potential mechanism of action on acne.

ObjectiveThis paper aims to observe the syndrome improvement and negative antigen conversion rate of Qingxuan Daozhi formula in the treatment of influenza in children (heat accumulation in the lung and stomach syndrome). MethodsThrough a multi-center randomized controlled methodology design,confirmed influenza cases were collected from October 2022 to April 2023 in the pediatrics department of eight hospitals,such as Dongfang Hospital of Beijing University of Chinese Medicine. A total of 180 children with influenza and heat accumulation in the lung and stomach syndrome conforming to the standard were recruited through the clinic. The sick children meeting the inclusion criteria were randomly divided into groups by a block-randomized method. The children in the experimental group were treated with Qingxuan Daozhi formula for five days,and those in the control group were treated with Oseltamivir Phosphate Granules for five days. The primary efficacy indicator was the negative conversion rate of influenza antigen detection. Secondary efficacy indicators were the Canadian acute respiratory illness and flu scale (CARIFS) and the incidence of complications,severe cases, and critical cases. Follow-up observation was conducted on the day of enrollment,48 hours after medication,72 hours after medication, and (6+1) d after medication. ResultsOne hundred and eighty participants were randomly assigned to the experimental group (90 cases) or the control group (90 cases). All participants were followed up during the study. Comparison of influenza antigen detection results in the primary efficacy indicators showed that the average time of negative influenza antigen conversion in the experimental group was (5.29±1.25) d,and that in the control group was (5.40±1.68) d,without a statistically significant difference. After five days of intervention,52 cases in the experimental group and 51 cases in the control group converted to negative,without a statistically significant difference. CARIFS score results in the secondary efficacy indicators showed that during 72 hours after intervention,there were statistically significant differences between the experimental group and the control group in three dimensions, including headache,muscle soreness, and the need for extra care (P<0.05). On the (6+1) days after the intervention,the differences in both the experimental group and the control group were statistically significant in 10 dimensions, including sore throat,bad sleep,uncomfortable feeling,poor spirit and fatigue,crying more than usual,the need for extra care,symptom,function,influence on parents,and total score (P<0.05). The comparison results within the group in the dimensional scores of symptom, function, and influence on parents,as well as the CARIFS total score showed that with the delay of follow-up time,scores of both groups decreased significantly,with a statistically significant difference (P<0.01). Inter-group comparison results showed that the mean score of the experimental group was higher than that of the control group at the time of enrollment. With the progress of intervention,the score of the experimental group was significantly decreased compared with that of the control group. At the end of follow-up,the mean score of the experimental group was lower than that of the control group,with no statistically significant difference. In terms of the incidence of complications,severe cases, and critical cases, there were no complications,severe cases, and critical cases in the two groups,without a statistically significant difference. ConclusionThe symptom improvement effect and negative antigen conversion rate of Qingxuan Daozhi formula in the treatment of influenza in children (heat accumulation in the lung and stomach syndrome) are not inferior to Oseltamivir Phosphate granules, and children's acceptance is better. It can be more widely used in clinical treatment of influenza in children (heat accumulation in the lung and stomach syndrome).
