The Pharmacovigilance Guidelines for Clinical Application of Oral Chinese Patent Medicines （hereinafter referred to as the Guidelines） is first specialized in the field of drug safety for oral Chinese patent medicines （OCPMs） in China. Rooted in China's healthcare context， the Guidelines address the unique usage patterns and risk characteristics of OCPMs， filling a regulatory gap in the pharmacovigilance framework specific to this category. To facilitate accurate understanding and effective implementation of the Guidelines， and to promote the standardized development of pharmacovigilance practices for OCPMs， this study offered a systematic interpretation based on its three core components. In the domain of risk monitoring and reporting， the paper analyzed the rationale for multi-source information integration and clarified the criteria for identifying key products and target populations for intensive monitoring. Regarding risk assessment， the Guidelines were examined from three dimensions of formulation components， medication behaviors， and population to address complex safety issues arising from medicinal constituents， irrational use， and individual susceptibility. In the area of risk control， the analysis focused on context-based interventions and dynamic closed-loop management strategies， exploring practical pathways to shift from passive response to proactive risk mitigation. Furthermore， this paper evaluated the applied value of the Guidelines and identified implementation challenges， such as insufficient capacity at the primary-care level and limited digital infrastructure. In response， the study proposed optimization strategies including establishing a dynamic updating mechanism， strengthening training at the grassroots level， and incorporating artificial intelligence to enhance pharmacovigilance capacity. This interpretation aims to provide actionable insights for marketing authorization holders （including manufacturers）， pharmaceutical distributors， healthcare institutions， and research organizations， ultimately supporting the establishment and refinement of a full lifecycle pharmacovigilance system for OCPMs.

Objective: To systematically characterize the developmental trajectory and interdisciplinary integration of intelligent diagnosis in traditional Chinese medicine (TCM) through quantitative topic evolution analysis, we addressed the fragmentation of existing research and clarified the long-term research structure and evolutionary patterns of the field. Methods: A topic evolution analysis was performed on Chinese-language literature pertaining to intelligent diagnosis in TCM. Publications were retrieved from the China National Knowledge Infrastructure (CNKI), Wanfang Data, and China Science and Technology Journal Database (VIP), covering the period from database inception to July 3, 2025. A hybrid segmentation approach, based on cumulative publication growth trends and inflection point detection, was applied to divide the research timeline into distinct stages. Subsequently, the latent Dirichlet allocation (LDA) model was used to extract research topics, followed by alignment and evolutionary analysis of topics across different stages. Results: A total of 3 919 publications published between 2003 and 2025 were included, and the research trajectory was divided into five stages based on data-driven breakpoint detection. The field exhibited a clear evolutionary shift from early rule-based systems and tongue-pulse image and signal analysis (2006 – 2010), to machine-learning-based syndrome and prescription modeling (2011 – 2015), followed by deep-learning-driven pattern recognition and formula association (2016 – 2020). Since 2021, research has increasingly emphasized knowledge-graph construction, multimodal integration, and intelligent clinical decision-support systems, with recent studies (2024 – 2025) showing the emergence of large language models and agent-based diagnostic frameworks. Topic evolution analysis further revealed sustained cross-stage continuity in syndrome modeling and prescription association analysis, alongside the progressive consolidation of integrated intelligent diagnostic platforms. Conclusion By identifying key technological transitions and persistent core research themes, our findings offer a structured reference framework for the design of intelligent diagnostic systems, the construction of knowledge-driven clinical decision-support tools, and the alignment of AI models with TCM diagnostic logic. Importantly, the stage-based evolutionary insights derived from this analysis can inform future methodological choices, improve model interpretability and clinical applicability, and support the translation of intelligent TCM diagnosis from experimental research to real-world clinical practice.

Stroke is the leading cause of death and disability among adults in China， and its common complications include digestive system abnormalities， cognitive impairment， depression， stroke-associated pneumonia， and hemiplegia. The combination of traditional Chinese and Western medicine has great potential in treating post-stroke complications. Xinglou Chengqitang （XLCQT） is a representative prescription of alleviating the disease in the upper part by treating the lower part. It has definite therapeutic effect and high safety. Clinically， XLCQT is often used to treat stroke and its complications. However， the quantity and quality of clinical trials of XLCQT in treating post-stroke complications need to be improved. Additionally， since the basic research is weak， the material basis and multi-target mechanism for the efficacy of this prescription are unknown. This article reviews XLCQT in terms of the pharmacodynamic basis， medicinal properties， safety evaluation， and progress in clinical research and mechanisms in treating post-stroke complications. This article summarizes 22 key active ingredients of XLCQT in treating acute stroke complicated with syndrome of phlegm heat and fu-organ excess. Among these key active ingredients， resveratrol， kaempferol， luteolin， chrysoeriol， apigenin， （+）-catechin， and adenosine have good pharmacokinetic properties and high bioavailability. The mechanisms of XLCQT in treating post-stroke complications are complex， including inflammatory response， brain-gut axis， hypothalamic-pituitary-adrenal （HPA） axis， intestinal flora， neurotrophic factors， autophagy， oxidative stress， and free radical damage. This review helps to deeply understand the pharmacodynamic basis and mechanisms of XLCQT in treating post-stroke complications and provides a theoretical basis for the clinical application of XLCQT against post-stroke complications and the development of drugs.

ObjectiveTo explore the associations among depressive symptoms, psychological resilience, and mental health literacy in adolescents, so as to provide new insights for interventions targeting adolescent depressive symptoms. MethodsA stratified multistage cluster sampling method was employed to select 2 723 students aged 10‒18 years from primary and secondary schools at different educational stages in Putuo District of Shanghai from December 2024 to January 2025. The Patient Health Questionnaire-9 (PHQ-9, total score0‒27, with a score ≥10 indicating positive depressive symptoms), the Resilience Scale for Chinese Adolescents (RSCA , total score 27‒135), and a mental health core knowledge awareness questionnaire (total score 0‒10) were utilized to assess depressive symptoms, psychological resilience, and mental health literacy, respectively. A network model was constructed using the nine PHQ-9 items (including anhedonia, depressed mood, sleep problems, fatigue, appetite problems, guilt, trouble concentrating, psychomotor symptoms, and self-harm or suicidal thoughts), five RSCA dimensions (including goal orientation, emotion regulation, positive cognition, family support, and interpersonal assistance), and the total mental health literacy score as nodes to analyze the association structure among these nodes. Standardized node strength, standardized expected influence, and standardized bridge expected influence were calculated. ResultsThe PHQ-9 score was 4.62±5.27, yielding a positive screening rate for depressive symptoms of 15.28%. The scores of the RSCA and mental health literacy were 97.71±20.58 and 9.00 (8.00, 10.00), respectively. Network analyses revealed that emotion regulation and depressed mood were core nodes in the network (standardized strength values were 1.74 and 0.97); they constituted the main connection between depressive symptoms and psychological resilience networks (edge weight was -0.17). Mental health literacy and positive cognition served as the main bridge nodes linking depressive symptoms and psychological resilience (standardized bridge expected influence values were 1.42 and 1.27). ConclusionDepressed mood, emotion regulation, positive cognition, and mental health literacy are closely associated with depressive symptoms, psychological resilience, and mental health literacy in adolescents. Strengthening interventions targeting emotion regulation, positive cognition and mental health literacy may contribute to the prevention and control of depressive symptoms among adolescents.

Objective To analyze white matter hyperintensities(WMH)and 11C-CFT PET/CT characteristics in patients with PD,and explore their relationship.Methods A total of 84 PD pa-tients admitted to our department between March 2021 and March 2025 were retrospectively en-rolled,and they were divided into young group(33 cases)and elderly group(aged＞65 years,51 cases)and also into non-WMH group(22 cases)and WMH group(62 cases)based on the severity of WMH.The degree of white matter lesions was scored,including periventricular white matter hyperintense(PVH)score and deep white matter hyperintense(DWMH)score.All patients un-derwent head MRI and 11C-CFT-PET/CT scanning.The T/N value and asymmetry index were calculated.Results The elderly PD patients exhibited significantly advanced age and higher H-Y stages,but lower T/N values of affected side of caudate nucleus,contralateral caudate nucleus,affected side of anterior putamen,contralateral anterior putamen and contralateral posterior puta-men,and posterior putamen asymmetry index than the young patients(P＜0.05,P＜0.01).Simi-lar results were observed in the WMH group when compared with the non-WMH group(P＜0.05,P＜0.01).The PVH score was negatively correlated with the T/N values of affected side of caudate nucleus(r=-0.282,P=0.009),contralateral caudate nucleus(r=-0.215,P=0.049),affected side of anterior putamen(r=-0.249,P=0.022),contralateral anterior putamen(r=-0.280,P=0.010)and contralateral posterior putamen(r=-0.285,P=0.009),and DWMH score was also negatively correlated with the T/N values in the affected side of caudate nucleus and affected side of anterior putamen(P＜0.05).Conclusion Both age and disease severity impact WMH and dopaminergic system in PD patients.A higher WMH load is associated with dopamin-ergic neuronal damage.

Objective:To investigate the targets and mechanisms of cycloastragenol in ameliorating azithromycin-induced drug-induced liver injury(DILI)based on network pharmacology and in vitro experiment validation.Methods:Potential targets of cycloastragenol and DILI were predicted using databases.The common and key targets were screened and subjected to GO and KEGG enrichment analyses,as well as molecular docking validation.Primary hepatocytes from C57BL/6 mice were isolated.The optimal concentration and time for azithromycin-induced DILI in mouse primary hepatocytes were determined using CCK8 and ROS assays.The expression of genes and proteins such as NF-κB p65,p-NF-κB p65,AMPKα,and p-AMPKα was assessed using RT-qPCR and Western blot to evaluate the intervention effect of cycloastragenol(10-50 μmol/L).Results:Network pharmacology analysis identified 10 key genes related to cycloastragenol's improvement of DILI,including heat shock protein 90AA1(HSP90AA1),matrix metalloproteinase 2(MMP2),etc.GO enrichment analysis suggested that cycloastragenol primarily regulates biological processes such as membrane potential and chemical synaptic transmission,and affects cellular components such as neuronal cell bodies and distal axons,and related kinase activities.KEGG enrichment analysis showed that it mainly exerts intervention effects through neuro-signaling pathways and IL-17 signaling pathways.Molecular docking demonstrated strong binding of cycloastragenol to HSP90AA1,MMP2,NF-κB p65,AMPKα,nuclear factor erythroid 2-related factor 2(Nrf2),heme oxygenase 1(HO-1),and NAD(P)H:quinone oxidoreductase 1(NQO1),with a binding energy≤-5.0 kcal/mol for Nrf2.In vitro experiments showed that azithromycin(50 μmol/L,12 h)significantly reduced hepatocyte viability and increased ROS levels(P＜0.01).Different concentrations of cycloastragenol significantly improved the activity of mouse primary hepatocytes,reduced the generation of intracellular ROS,downregulated the phosphorylation level of NF-κB p65,and upregulated the mRNA and protein levels of AMPKα,Nrf2,HO-1,NQO1(P＜0.05).Conclusions:Cycloastragenol may alleviate azithromycin-induced hepatocyte oxidative stress and inflammation by inhibiting NF-κB phosphorylation and activating the AMPK/Nrf2/HO-1/NQO1 pathway,with its mechanism likely closely linked to targeting Nrf2.However,the complex mechanisms of DILI may involve additional unverified pathways.Therefore,further studies are necessary to validate the efficacy and safety of cycloastragenol in animal models.

Objective:To investigate the role of vitamin E succinate (VES) in inducing autophagy of human gastric cancer cells by activating calcium redistribution through inositol 1, 4, 5-trisphosphate receptors (IP 3R) pathway. Methods:Human gastric cancer lines MKN28 (moderately differentiated) and MKN45 (poorly differentiated) cells were cultured in vitro in March 2022. Gastric cancer cells were treated with VES at different doses for 24 h, and cell viability was measured by CCK-8 method to determine VES dose for subsequent study. The experiment was set up with solvent control group (0.1% ethanol), VES dose groups, 100 nmol/L rapamycin (RAPA) as autophagy positive control group (RAPA group), 15 μg/ml tunicamycin (TM) was used as the endoplasmic reticulum stress (ERS) positive control group (TM group), 10 μmol/ml 2-aminoethyl diphenylborinate (2-APB group) was used to inhibit IP 3R (2-APB group) and VES+2-APB group. The occurrence of autophagosomes in gastric cancer cells was observed by transmission electron microscopy, and microtubule associated protein 1 light chain 3 (LC3), Beclin1, IP 3R, glucose-regulated protein 75 (Grp75), voltage-dependent anion channel 1 (VDAC1) protein expression was detected by western blotting. Fluo-4 AM was used to label intracellular calcium ions, Rhod-2 AM was used to label mitochondrial calcium ions, and the fluorescence intensity of calcium ions was observed by fluorescence microscope. One-way analysis of variance was used to compare the means among multiple groups, and LSD- t method was used for pairwise comparison. Results:CCK-8 results showed that compared with solvent control group, the proliferation rates of MKN28 cells in 10-100 μg/ml VES group and MKN45 cells in 20-100 μg/ml VES group were significantly decreased ( P<0.05). Subsequent VES dosages were determined according to the growth curve, MKN28 was 5, 10, 20, 40 μg/ml, and MKN45 was 10, 20, 40, 80 μg/ml. The results of transmission electron microscopy and fluorescence showed that autophagosomes were formed in MKN28 cells in 5 and 20 μg/ml VES groups and MKN45 cells in 10 and 40 μg/ml VES groups, and the fluorescence intensity of calcium ions in cytoplasm and mitochondria was significantly higher than that in solvent control group ( P<0.05). Compared with solvent control group, LC3, Beclin1, IP 3R, Grp75 and VDAC1 protein expressions of MKN28 cells in 20 and 40 μg/ml VES groups and MKN45 cells in 40 and 80 μg/ml VES groups were significantly increased ( P<0.05). After inhibiting IP 3R with 2-APB, the expression levels of IP 3R, Grp75 and VDAC1 in two kinds of gastric cancer cells in VES+2-APB group were significantly decreased compared with VES group ( P<0.05). The fluorescence results showed that the fluorescence intensity of cytoplasmic and mitochondrial calcium ions in VES+2-APB groups was significantly lower than that in VES group ( P<0.05). Compared with VES group, LC3 and Beclin1 protein expressions in two kinds of gastric cancer cells in VES+2-APB groups were significantly decreased ( P<0.05) . Conclusion:VES may activate intracellular calcium redistribution through IP 3R-Grp75-VDAC1 calcium channel and induce autophagy in gastric cancer cells.

Coronary heart disease with angina pectoris,characterized by myocardial ischemic injury as its fundamental pathological mechanism,represents a prevalent cardiovascular condition.The"State-Target Differential Diagnosis and Treatment"presents a holistic regulatory framework,integrating macroscopic state regulation with microscopic targeting.Guided by this approach,the pathological evolution of coronary heart disease is examined through four dimensions:"state-target-cause-effect."The"cause"encompasses both the pathogenesis and etiological factors of traditional Chinese and Western medicine.The"effect"manifests as adverse cardiovascular events,including myocardial infarction and heart failure.The"state"delineates the progressive development pattern of qi to blood to deficiency,beginning with qi stagnation and cold congealment in the initial stage,followed by blood stasis and phlegm obstruction in the intermediate stage,and culminating in qi-blood deficiency in the advanced stage.The"target"encompasses multi-level therapeutic interventions addressing both symptomatic manifestations and clinical indicators.Building on this theoretical foundation,this research focuses on the pattern of qi sinking and blood stasis commonly observed in late-stage angina,systematically elucidating its state regulation and targeting therapeutic strategies.Using the clinical empirical formula Shengxian Quyu Decoction as the baseline state prescription,an in-depth investigation was conducted to determine optimal combination patterns of symptom-and biomarker-targeted medications.This study aims to establish a modernized differential treatment system for angina pectoris with the pattern of qi sinking and blood stasis,providing novel research perspectives and theoretical foundations for enhancing clinical efficacy and reducing the risk of cardiovascular events.

Objective·To investigate the effect of Th17 cell-specific Stat3 knockout on anxiety-and depressive-like behaviors.Methods·Mice with specific Stat3 knockout in Th17 cells(Stat3fl/fl;Il17a-CreERT2),named Stat3△Il17a,and wild-type mice(Stat3fl/fl,WT)were generated through the Cre/LoxP system,and Stat3 knockout was induced by intraperitoneal injection of tamoxifen.CD4+T cells were isolated using magnetic-activated cell sorting and induced to differentiate into Th17 cells.Reverse transcription polymerase chain reaction and Western blotting were used to verify Stat3 knockout efficiency.Mice were assigned into 4 groups:WT-C group,Stat3△Il17a-C group,WT-P group,and Stat3△Il17a-P group.The periodontitis model was established in the WT-P group and the Stat3△Il17a-P group by injection of Porphyromonas gingivalis-lipopolysaccharide(P.gingivalis-LPS)into the gingival sulcus.Behavioral tests,including the open field test,elevated zero maze,and forced swimming test,were conducted to evaluate changes in anxiety-and depressive-like behaviors.Micro-computed tomography was used to observe destruction of alveolar bone.Neuronal injury was observed by H-E staining,and the level of brain-derived neurotrophic factor(BDNF)was detected by enzyme-linked immunosorbent assay.Results·mRNA expression and protein levels of Stat3 in Stat3△Il17a mice were inhibited compared to WT mice(P<0.05).Experimental periodontitis model was successfully established in the WT-P group and the Stat3△Il17a-P group.The degree of alveolar bone destruction was reduced in the Stat3△Il17a-P group compared to the WT-P group.In the WT-P group,decreased residence time in the central area and in the open area was observed in the open field test and elevated zero maze respectively,and increased immortal time was recorded in the forced swimming test(P<0.05).Moreover,neuronal injury was detected and significantly decreased expression levels of BDNF in the brain were measured in the WT-P group compared with the WT-C group(P<0.05).The degree of abnormal behaviors and neuronal injury was reduced in the Stat3△Il17a-P group compared to the WT-P group(P<0.05).Moreover,the level of BDNF in the Stat3△Il17a-P was higher than that in the WT-P group(P<0.05).Conclusion·Periodontitis may contribute to anxiety-and depressive-like behaviors and neuronal damage in mice,while Th17-specific conditional knockout of Stat3 could significantly alleviate pathological behaviors and neuronal damage.Stat3-mediated-Th17 cell immune responses may play a crucial role in the correlation between periodontitis and anxiety and depression.

Objective To explore the role of X chromosome encoded epigenetic regulator UTX in NK cell-mediated anti-tumor activity.Methods Male Ncr1-iCre mice were crossed with female UTXfl/fl mice to generate F1 Ncr1-iCre+UTXfl/-male mice,which were further crossed with female UTXfl/fl mice to obtain male Ncr1-iCre-UTX fl/-control mice(M-Con)and NK-specific deletion of UTX male mice Ncr1-iCre+UTXfl/-(M-KO),as well as female Ncr1-iCre-UTXfl/fl control mice(F-Con)and UTX-deficient female mice Ncr1-iCre+UTXfl/fl(F-KO).UTX-deficient mice were injected with melanoma cell line B16F10 via tail vein to observe pulmonary metastatic tumor nodules.Moreover,flow cytometry was applied to detect the proportion and quantity of pulmonary NK cells(CD3-CD19-NK1.1+),maturation makers KLRG1 and CD11b,activation receptors NKG2D and CD69,and effector molecules,including perforin,granzyme B,CD107a,and IFN-γ.Then pulmonary NK cells were sorted and co-cultured with B16F10 cells,and the apoptosis of the melanoma cells was measured with flow cytometry.Results Compared with the M-Con mice,the M-KO mice presented less number of pulmonary tumor nodules(P<0.05),increased proportion and quantity of NK cells in the tumor microenvironment(P<0.01),though no obvious changes in the ratio of NK maturation makers KLRG1 to CD11b,enhanced expression level of cytotoxic molecule perforin(P<0.01),but no changes in the expression of effector molecule granzyme B,degranulation marker CD107a and cytokine IFN-γ in NK cells.Co-culture of NK cells and B16F10 cells promoted the apoptosis of tumor cells(P<0.05).Compared with the F-Con mice,the F-KO mice had no statistical difference in the number of pulmonary tumor nodules,but larger proportion and number of NK cells(P<0.05),decreased ratio of KLRG1 to CD11b(P<0.01),elevated level of perforin but decreased levels of granzyme B,CD107a and IFN-γ in NK cells(P<0.01).The co-culture of NK cells and B16F10 cells reduced the apoptosis of tumor cells in F-KO female mice(P<0.05).Conclusion NK-specific deletion of UTX regulates pulmonary metastasis of melanoma in a sex-dependent manner.
