As the core vehicle for preserving and transmitting traditional Chinese medicine(TCM) academic thought and clinical experience, the establishment of a robust quality evaluation system for TCM clinical case reports is a crucial component in the current standardization and modernization of TCM. Based on the practical experience of constructing the China Clinical Cases Library of Traditional Chinese Medicine by the China Association of Chinese Medicine, this study conducted a comprehensive analysis of critical challenges, including insufficient authenticity and unfocused evaluation criteria. It proposed a three-dimensional evaluation framework grounded in the structure-process-outcome logic, encompassing three dimensions of authenticity and standardization, characteristics and advantages, application and translational impact. This framework integrated 12 key evaluation indicators in a systematic manner. The model preserved the academic characteristics of TCM syndrome differentiation and treatment, while aligning with modern scientific research standards, achieving a balance between individualized TCM experience and standardized evaluation. Concurrently, this study provided theoretical foundations and methodological guidance for evaluating the quality of TCM clinical cases, contributing significantly to the inheritance of TCM knowledge, evidence-based practice, and the reform of talent evaluation mechanisms.

Small cell lung cancer (SCLC) is characterized by rapid onset, high invasiveness, and a strong tendency for recurrence and metastasis, which aligns with the pathogenic characteristics of wind pathogen in traditional Chinese medicine (TCM). This paper explores the pathological mechanism and dynamic pattern identification and treatment of SCLC from the perspective of "internal wind in hidden circulation". It is proposed that the core pathogenesis of SCLC is rooted in depletion of healthy qi, with binding of phlegm, stasis, and toxin. When pathogenic factors become excessive, the ascending and descending of yang qi becomes disordered, transforming into wind. This leads to internal wind in hidden circulation, which moves erratically and damages healthy qi. In the limited stage, cancer toxin accumulates and internal wind arises covertly, treatment for which should focus on regulating qi and resolving toxin, defending against wind and resisting pathogen with modified Bufei Decoction (补肺汤) and Shengjiang Powder (升降散). In the early extensive stage, phlegm and stasis generate wind, and internal wind spreads through collate-rals; treatment should resolve phlegm and dispel stasis, extinguish wind and resolve toxin, with modified Lingjiao Gouteng Decoction (羚角钩藤汤) combined with Tianma Gouteng Beverage (天麻钩藤饮). During the treatment stage, there is qi and yin depletion, and deficient wind harassing the interior, for which it is recommended to boost qi and nourish yin, soften the liver and extinguish wind, with modified Zhengan Xifeng Decoction (镇肝熄风汤) combined with Qingzao Jiufei Decoction (清燥救肺汤). In the progression stage, internal wind stirs again and cancer toxin scurries; treatment should focus on strengthening the healthy qi and replenishing essence, restraining wind and penetrating toxin, with modified Sanjia Fumai Decoction (三甲复脉汤). In the terminal stage, yin and yang are on the verge of dissociation and depleted yang floats upward; treatment should constrain and astringe to prevent collapse, rescue yang and contain yin, with modified Dihuang Drink (地黄饮子) combined with Laifu Decoction (来复汤).

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).

To summarize the clinical experience of Professor LIU Jinmin in treatment for epilepsy. It is believed that main pathogenesis of epilepsy is yangming failure to close and vital activity loss control, so a therapeutic approach focused on restoring the closure of yangming and regaining vital activity was proposed for the treatment of epilepsy. For excess syndrome, the treatment focuses on draining excess and descending qi, promoting purgation and restoring spirit. When yangming dryness-heat predominates, the approach involves unblock the bowels and regulating the spirit, descending qi and reducing fire, with modified Chengqi Decoction (承气汤) as prescription; when yangming phlegm-fire predominates, the treatment focuses on clearing heat and resolving phlegm, calming mind and suppressing fright, with modified Qingxin Wendan Decoction (清心温胆汤) as prescription; when yangming blood stasis predominates, the approach involves breaking up blood stasis and promoting purgation, eliminating stasis and awakening the mind, with Taoren Chengqi Decoction (桃核承气汤) as prescription. For deficiency syndrome, the treatment emphasizes tonifying deficiency and raising qi, strengthening the stomach and nourishing the spirit. When center qi deficiency and sinking of clear qi of the nutrients from food, the approach involves replenishing and uplifting qi while nourishing vital activity, with modified Liujunzi Decoction (六君子汤) as prescription; when yin deficiency and fluid consumption, the treatment focuses on nourishing stomach and tonifying yin, promoting fluid production and calming the spirit, with modified Maimendong Decoction (麦门冬汤) combined with Yiwei Decoction (益胃汤) as prescriptions. In clinical situations of deficiency-excess complex, it is essential to distinguish the primary condition from the secondary, applying both supplementing and draining methods flexibly to achieve optimal treatment.

ObjectiveTo investigate the efficacy and underlying mechanisms of Gynostemma pentaphyllum alcohol extract in improving glucose and lipid metabolism disorders in db/db mice through transcriptomics and gut microbiota analysis. MethodsEighteen db/db mice were randomly assigned to the model(DM) group, metformin(MET) group, and G. pentaphyllum alcohol extract(GP) group, with six mice in each group, based on stratification of fasting blood glucose and body weight. An additional six db/m mice were selected as the normal control(NC) group. Mice in the NC and DM groups were administered deionized water (10 mL·kg-1) daily. The MET group received metformin (0.195 g·kg-1) by gavage. The GP group was treated with G. pentaphyllum alcohol extract (3.9 g·kg-1) by gavage for six weeks. Fasting blood glucose was measured every two weeks. After six weeks of intervention, serum levels of total cholesterol (TC), triglycerides (TG), low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), aspartate aminotransferase (AST), alanine aminotransferase (ALT), creatinine (CREA), and blood urea nitrogen (BUN) were assessed. Enzyme-linked immunosorbent assay (ELISA) was used to measure insulin (FINS), adiponectin (ADP), and tumor necrosis factor-α (TNF-α). Hematoxylin-eosin (HE) staining was used to observe liver histomorphology, periodic acid-Schiff (PAS) staining was employed to assess hepatic glycogen synthesis, and Oil Red O staining was used to detect hepatic lipid deposition. Liver transcriptomic data were used to identify differentially expressed genes in the liver and conduct enrichment analysis. Real-time PCR was employed to verify the expression levels of adiponectin gene (Adipoq), peroxisome proliferator-activated receptor gamma coactivator-1α (PGC-1α), AMP-activated protein kinase (AMPK), peroxisome proliferator-activated receptor α (PPARα), glucokinase (GCK), forkhead box (Fox)O1, FoxO3, phosphoenolpyruvate carboxykinase (PEPCK), and glucose-6-phosphatase (G6PC). Metagenomic sequencing was conducted to analyze changes in gut microbiota composition. ResultsCompared with the NC group, the DM group exhibited significantly elevated fasting blood glucose (P<0.01), serum AST, ALT, TC, TG, LDL-C, and HDL-C (P<0.01). FINS, homeostatic model assessment for insulin resistance (HOMA-IR), and the inflammatory cytokine TNF-α were significantly increased (P<0.01), while ADP was significantly decreased (P<0.05). Histological analysis confirmed severe hepatic steatosis and excessive lipid accumulation in the DM group, along with markedly reduced glycogen synthesis. Compared with the DM group, the GP group showed significantly decreased fasting blood glucose (P<0.01), reduced serum TC, LDL-C, and HDL-C levels (P<0.05), significantly decreased serum TG and AST levels (P<0.01), significantly reduced FINS, HOMA-IR, and TNF-α levels (P<0.01), and significantly increased ADP (P<0.01). Hepatic steatosis and lipid deposition were significantly alleviated, while glycogen synthesis was markedly enhanced. Transcriptomic differential and enrichment analyses suggested that the mechanisms by which G. pentaphyllum alcohol extract improved hepatic glucose and lipid metabolism in db/db mice may involve regulation of the AMPK and FoxO signaling pathways. Real-time PCR results confirmed that expression of PGC-1α, PEPCK, G6PC, FoxO1, and FoxO3 was significantly downregulated following treatment with G. pentaphyllum alcohol extract (P<0.05, P<0.01), whereas mRNA expression of Adipoq, PPARα, GCK, and AMPK was significantly upregulated (P<0.05, P<0.01). Metagenomic analysis showed that the relative abundance of Lactobacillus, Alistipes, and Akkermansia species was higher in the GP group than in the DM group. ConclusionG. pentaphyllum alcohol extract may improve glucose and lipid metabolism disorders in db/db mice by regulating the hepatic AMPK/PPARα pathway to suppress lipid deposition and alleviate hepatic steatosis, by inhibiting gluconeogenesis through the AMPK/PGC-1α and FoxO pathways to lower fasting blood glucose, and by increasing the abundance of beneficial gut bacteria such as Lactobacillus, Alistipes, and Akkermansia to restore gut microbiota balance.
