OBJECTIVE To study the pharmacokinetic characteristics of antidepressant active components from Jiaotai pills in healthy subjects. METHODS Eight healthy subjects (3 males and 5 females) were recruited and given a single oral dose of 8.55 g of Jiaotai pills. Venous blood samples were collected before administration (0 h) and at intervals from 0.25 to 36.0 hours post- administration. After treating the plasma samples with protein precipitation, the blood concentrations of the antidepressant active ingredients (coptisine, berberine, magnoflorine, and palmatine) in Jiaotai pills were determined using liquid chromatography- tandem mass spectrometry (LC-MS/MS) method. DAS 2.0 software was employed to calculate the pharmacokinetic parameters of healthy subjects [half-life (t1/2), peak concentration (cmax), time to peak concentration (tmax), area under the concentration-time curve (AUC), and mean residence time (MRT)] using a non-compartmental model. RESULTS After healthy subjects took Jiaotai pills, the drug-time curve of the four antidepressant active ingredients conforms to a two-compartment model and tmax values were similar, with all reaching peak blood concentrations within 2.00 to 4.00 hours post-administration. However, the t1/2 and MRT of coptisine and berberine were significantly longer than that of magnoflorine and palmatine. There were also significant differences in the AUC and cmax among the four antidepressant active ingredients, with magnoflorine exhibiting markedly higher AUC0-t and cmax compared to the other three components. CONCLUSIONS In this study,LC-MS/MS is used to analyze the pharmacokinetic characteristics of the antidepressant active ingredients from Jiaotai pills in healthy subjects, can provide valuable references for the clinical application of Jiaotai pills.

Bronchial asthma (abbreviated as asthma) is one of the common inflammatory diseases in the chronic airway of the respiratory system. Recurrent wheezing,shortness of breath,chest tightness, and cough are the main symptoms,which are easy to repeat,protracted and difficult to cure,and seriously affect the patients' life quality. The Janus kinases (JAK)/signal transducers and activators of transcription (STAT) signaling pathway is involved in the regulation of cellular inflammatory response,oxidative stress,apoptosis, and other biological processes. It plays a key role in the occurrence and development of asthma. Traditional Chinese medicine intervenes in asthma based on the JAK/STAT signaling pathway in multiple stages and targets. The specific mechanism is related to inhibiting airway inflammation and anti-oxidative stress,alleviating airway remodeling,affecting airway mucus hypersecretion,inhibiting high airway response, and regulating immune response,which demonstrates the characteristics and advantages of traditional Chinese medicine in treating asthma. Based on this,by referring to relevant literature,this paper systematically sorted out the JAK/STAT signaling pathway and its action mechanism in the occurrence and development of asthma. It also systematically summarized the efficacy and specific mechanism of monomers, compounds, and compound formulas of traditional Chinese medicine, as well as the external treatment methods by regulating the JAK/STAT signaling pathway to intervene in asthma. It aims to effectively prevent and control the occurrence and development of asthma in clinic, providing a reference for the methods of prevention and treatment of asthma with traditional Chinese medicine.

Digestive system malignant tumors (DT) are one of the leading causes of death globally and carry a heavy economic burden. Gut microbiota plays a critical role in maintaining host health, including providing nutrition, defending against pathogens, and promoting immune development. In recent years, more and more studies have shown that dysbiosis of gut microbiota is closely associated with DT such as gastric cancer, liver cancer, and colon cancer. Therefore, targeted regulation of gut microbiota plays a potential role in inhibiting the growth and metastasis of DT, while its specific regulatory mechanism remains unclear. As the studies about the anti-tumor effects of traditional Chinese medicine (TCM), especially the basic and clinical studies on the regulation of gut microbiota by TCM in tumor treatment, have been growing, the therapeutic effects of TCM on DT have attracted much attention. This paper provides a systematic review of the relationship between gut microbiota and DT, as well as the related studies on the modulation of gut microbiota by TCM against DT, with the aim of providing a foundation and direction for future basic and clinical studies on DT. The literature review shows that gut microbiota influence the occurrence and development of DT through multiple pathways. These pathways include triggering chronic inflammation, producing oncogenic metabolites, inducing genomic instability, regulating the immune system, and altering the tumor microenvironment. TCM can exert anti-DT effects by regulating the composition of gut microbiota, modulating gut microbiota metabolites, repairing intestinal barrier function, and influencing immune functions. Therefore, understanding the relationship between gut microbiota and DT and the regulatory mechanisms of TCM may provide new strategies for future prevention and treatment of DT.

The diagnosis of occupational radiation diseases, with the diagnostic criteria as main technical basis, has always been one of the emphases of China's occupational health work. This study compared the diagnostic standards for occupational radiation diseases between China and the International Labour Organization (ILO) across three aspects—types, classifications/grades, and diagnostic dose requirements—categorizing the diseases into tissue reactions and stochastic effects. ① For tissue reactions, 8 types are included both in China and ILO standards, 13 unique to China's standards, and 4 unique to the ILO standards; significant differences exist in classifaton/grading; China's standards are either consistent with or stricter (i.e., requiring higher diagnostic dose values) than the ILO standards. ② For stochastic effects (radiation-induced cancer), 12 types were included in both standards; China's standards provide more comprehensive coverage for certain malignancies (e.g., bone cancer); while 5 types were unique to the ILO standards have, some (e.g. salivary gland cancer) are primarily observed in non-occupational populations. Overall, China’s standards include more disease types and maintain more stringent diagnostic dose requirements. However, specific discrepancies require further deliberation during future revisions. Finally, based on these results, recommendations were provided for basic research and the evaluation of Chinese diagnostic criteria.

At present, the systematic excavation of the clinical experience and academic thought of the Sichuan school of Chinese medicine vis-à-vis its dominant disease entities remains fragmentary, and replicable paradigms are scarce. Confronted with empirical fragmentation, data heterogeneity and decision-making subjectivity, the standardised distillation, inheritance and clinical translation of these distinctive experiences has become a critical bottleneck constraining the development of the Sichuan school. The integration of artificial-intelligence technologies in data processing, pattern recognition and intelligent decision-making has rendered deep mining of traditional Chinese medicine(TCM) clinical knowledge and patterns imperative. Constructing an intelligent modern TCM diagnostic-therapeutic-evaluative system is now the obligatory route for inheritance and innovation in Chinese medicine, and simultaneously provides a technological breakthrough for intelligent decision paradigms in the dominant diseases of the Sichuan school. Accordingly, this study adopts the regional academic school as its point of entry, focuses on the dominant diseases of the Sichuan school, and proposes an innovative pathway of "four-dimensional data-multi-modal fusion-multi-agent decision-making". Specifically, four data dimensions are defined and instantiated: (Ⅰ) knowledge from classical medical literature and historical case records. (Ⅱ) objective four-diagnosis phenotypic data. (Ⅲ) master physicians' prescribing regularities. (Ⅳ) characteristic mechanisms of renowned formulae. Leveraging multi-modal data fusion and generative artificial intelligence, the entire causal chain of Famous Physicians and Renowned Formulas is explicated to reconstruct the diagnostic-therapeutic cognitive logic of the regional school. Finally, a multi-agent collective-decision model is established and refined for the dominant diseases of the Sichuan school, capable of generating precise, individualised treatment regimens and thereby advancing an intelligent diagnostic-therapeutic paradigm that delivers more efficient and accurate clinical decision support.

As traditional Chinese medicine (TCM) culture evolves, the academic thoughts of these practitioners, being a core component of TCM inheritance, are gradually shifting from traditional models to digital and intelligent approaches. However, this process faces challenges, including insufficient standardization of data collection and processing, low inheritance efficiency, and the risk of inheritance alienation. To address these issues, this paper proposed the construction of an intelligent platform following the "intelligence-transmission-modeling-linkage" path. "Intelligence" involves using smart perception technologies to accurately collect and classify diagnostic and therapeutic information from famous TCM practitioners, laying the foundation for digital inheritance; "transmission" focuses on leveraging artificial intelligence to mine and inherit the clinical experience of famous TCM practitioners, thereby establishing a "regional academic schools+group commonality" dynamic inheritance system; "modeling" integrates the academic thoughts and advantageous diseases of multiple schools to develop intelligent diagnostic and therapeutic models of famous TCM practitioners, resulting in personalized treatment plans; "linkage" involves constructing a clinical decision support system of famous TCM practitioners by integrating blockchain and generative intelligence, creating an AI digital avatar of TCM diagnostic and therapeutic knowledge. The "intelligence-transmission-modeling-linkage" intelligent inheritance model not only provides new ideas for the digital inheritance of TCM academic schools, but also offers strong support for the modernization and internationalization of TCM.

Objective To investigate the public health issues associated with the follow-up outcomes of mental health in elderly community residents with a focus on mild cognitive impairment (MCI) and emotional problems (anxiety and depression), as the burden of various diseases increases with global population growth and aging. Methods In this study, Patient Health Questionnaire-9, Early Dementia Screening Scale, Montreal Cognitive Assessment, Generalized Anxiety Disorder Scale, Geriatric Depression Scale, and Activities of Daily Living scale were used to analyze the data on MCI and emotional problems among the elderly in a district of Shanghai, China. The t-test, Spearman correlation analysis, and linear regression analysis were used to identify related protective factors and evaluate the effectiveness of comprehensive intervention measures. Results The first session of intervention led to an improvement in cognitive impairment (P<0.001). During the first session of intervention, exercise and skill training were very effective in improving cognitive impairment (r=0.71 and 0.68, P<0.001), while group instruction and the distribution of educational materials failed to achieve an ideal effectiveness. The second session of intervention also had a significant effect on cognitive impairment (P<0.05); however, the second session of intervention lacked a significant overall effect, and skill training remained the most effective intervention method (Pr=0.0344, P<0.05). The research findings showed that the two sessions of community intervention were protective factors against MCI and depression, while they could not alleviate anxiety. Conclusion This study validates the effectiveness of follow-up intervention measures in improving cognitive function in elderly patients with MCI, which provide scientific prediction and reference for early screening, prediction, and follow-up intervention of elderly dementia and MCI at the community level.
