Postprandial drowsiness is a clinical condition characterized by pronounced drowsiness after meals， while The Inner Canon of Yellow Emperor （《黄帝内经》） associates this condition with wei qi （defensive qi）. By analyzing the original texts of The Inner Canon of Yellow Emperor and perspectives from many medical professionals， it is found that the transition between wakefulness and sleep depends on the mutual induction of yin and yang， and that the two pathways of wei qi circulation intersect at the spleen and stomach. Based on this， the core pathogenesis of postprandial drowsiness is proposed to be either upper jiao obstruction or spleen-stomach dysfunction， leading to the stagnation of wei qi internally， then the mutual induction of yin and yang causes inward invasion of wei qi in the body， resulting in drowsiness； at this stage， the stagnated and inward invasive wei qi converges at the spleen and stomach， then merges into the circulation of zang-fu organs， rerouting through the Foot Taiyang Meridian， forming a circulation pattern described as "circulating from yin to yang". Treatment should focus on the root and branch simultaneously， with the primary goal of regulating the circulation of wei qi； facilitating its transition from yin to yang to restore the sleep-wake cycle. By proposing the model of wei qi circulating from yin to yang， this study offers novel insights on the understanding of postprandial drowsiness.

AIM:To explore the effect of sinomenine hydrochloride(SH)on microcirculation and renal func-tion in type 2 diabetic db/db mice with a focus on the diacylglycerol(DAG)/protein kinase C(PKC)signaling pathway.METHODS:Eighteen 6-week-old male db/db mice were randomly divided into three groups:model group(saline),LY group(administered with 1 mg·kg-1·d-1 LY333531),and SH group(administered with 124.8 mg·kg-1·d-1 SH).Addi-tionally,6 age-matched db/m mice comprised the control group(saline).Daily intragastric administration lasted 6 weeks.Body mass,fasting blood glucose(FBG),urinary microalbumin(mALB),urinary creatinine(UCr)and urinary β2-micro-globulin(β2-MG)were measured in each group.The serum levels of endothelin-1(ET-1),endothelial nitric oxide syn-thase(eNOS),collagen type Ⅳ(Col Ⅳ)and laminin(LN),and the levels of DAG and PKC in renal tissues were ana-lyzed by enzyme-linked immunosorbent assay(ELISA).The morphological changes of renal tissues were assessed using HE and PAS staining,and kidney ultrastructure was examined via transmission electron microscopy.Immunohistochemis-try and Western blot were used to detect PKC and p-PKC levels in renal tissues.RESULTS:Compared with model group,the mice in both LY and SH groups showed decreased body mass(P＜0.05),with significantly reduced FBG level in LY group(P＜0.01).In addition,the urinary mALB and β2-MG levels were markedly decreased(P＜0.01),while UCr level was significantly increased(P＜0.01).Serum ET-1,Col Ⅳ and LN levels were significantly lower(P＜0.01),whereas eNOS level was notably higher(P＜0.01).Renal tissue DAG and PKC levels,as well as p-PKC expression were significantly reduced(P＜0.01).Improvements in renal tissue pathology and ultrastructure were observed.CONCLU-SION:Sinomenine hydrochloride improves microcirculation in diabetic db/db mice by modulating DAG/PKC signaling pathway,thus exerting protective effect on the kidney.

Integrated traditional Chinese and Western medicine refers to a clinical diagnosis and treatment model that incorporates the essence of traditional Chinese medicine in regard to treatment decisions based on syndrome differentiation and a reliance on modern western medicine as the basis of diagnosis and treatment.It is an organic combination of the two,with each bringing its own strengths into full play and complementing those of the other.After the founding of the People's Republic of China,the development of the integrated traditional Chinese and Western medicine has been increasingly valued.The unique advantages of the integration of traditional Chinese and Western medicine have been continuously utilized,resulting in fruitful achievements in theoretical inheritance and innovation and in the prevention and treatment of major diseases.Furthermore,integrated traditional Chinese and Western medicine has become a unique system of medicine of China.This article provides a review and elaboration of the entire process of the integration of traditional Chinese and Western medicine,including its significance,status of development,and achievements.It is suggested that,in the field of integrated traditional Chinese and Western medicine,efforts should made to delve into classic theories,identify the right entry points for integration,reconstruct and improve the theoretical system of integrated traditional Chinese and Western medicine by combining the cutting-edge achievements of modern medicine,and focus on enhancing clinical efficacy.

Innovative drugs are defined as new chemical entities that play a vital role in the treatment and maintenance of human health. While single-target innovative drugs have achieved notable success, they face limitations in addressing the increasingly complex and precise spectra of diseases. The advent of multi-target innovative drugs offers new opportunities, supported by a growing body of pharmacological evidence. Herbal medicines are recognized as valuable sources of multi-target therapeutics due to their proven efficacy in treating complex diseases. However, the identification and validation of such drugs from herbal sources continue to pose significant challenges. This paper presents a comprehensive review of the literature on traditional Chinese medicine, integrated medicine, chemistry, and biology from 2015 to 2025. It summarizes the strategies employed in integrating traditional Chinese and Western medicine for innovative drug development, along with successful application cases. We believe these efforts will deepen understanding of the current landscape, accelerate the discovery of multi-target innovative drugs from herbal medicine, and contribute to addressing major human health challenges.

Addressing the enduring challenge of evaluating traditional Chinese medicines (TCMs), the integrated evidence chain-based effectiveness evaluation of TCMs (Eff-iEC) has emerged. This paper explored its capacity through a demonstration study that evaluated the effectiveness evidence of six commonly used anti-hepatic fibrosis Chinese patent medicines (CPMs), including Biejiajian Pill (BP), Dahuang Zhechong Pill (DZP), Biejia Ruangan Compound (BRC), Fuzheng Huayu Capsule (FHC), Anluo Huaxian Pill (AHP), and Heluo Shugan Capsule (HSC), using both Eff-iEC and the Grading of Recommendations, Assessment, Development, and Evaluation (GRADE) system. The recognition of these CPMs within the TCM academic community was also assessed through their inclusion in relevant medical documents. Results showed that the evidence of BRC and FHC received higher assessments in both Eff-iEC and GRADE system, while the assessments for others varied. Analysis of community recognition revealed that Eff-iEC more accurately reflects the clinical value of these CPMs, exhibiting superior evaluative capabilities. By breaking through the conventional pattern of TCMs effectiveness evaluation, Eff-iEC offers a novel epistemology that better aligns with the clinical realities and reasoning of TCMs, providing a coherent methodology for clinical decision-making, new drug evaluations, and health policy formulation.

Fabry disease, a rare genetic disorder affecting multiple organs, has understudied correlations among enzyme activity, genotype, and clinical manifestations in patients of different sexes with classical and late-onset phenotypes. In this study, clinical data, α-Gal A activity, and GLA gene test results of 311 patients, who were categorized by classical and late-onset phenotypes, ⩽5% and > 5% of the normal mean value of enzyme activity, and truncated and nontruncated mutation groups, were collected. The common clinical manifestations of Fabry disease included acroparesthesia, hypohidrosis/anhidrosis, neuropsychiatric system, and renal and cardiovascular involvement. Multiorgan involvement was higher in males and classical phenotype patients. In both sexes, classical patients commonly presented with acroparesthesia and multiorgan involvement, whereas late-onset patients showed renal, neuropsychiatric, and cardiovascular involvement. Male and classical patients had lower enzyme activity than female and late-onset patients, respectively. Classical males with enzyme activity of ⩽5% of the normal mean level showed higher multiorgan involvement frequency than those with enzyme activity of > 5%, whereas no significant difference was observed among females. Ninety-five gene mutation sites were detected, with significant phenotype heterogeneity in patients with the same mutation. No significant difference in enzyme activity or clinical manifestations was observed between truncated and nontruncated mutations. Overall, male patients with Fabry disease, regardless of classical or late-onset phenotype, have a higher frequency of multiple-organ involvement and lower α-Gal A activity than female patients. α-Gal A activity was closely correlated with clinical symptoms in males but weakly correlated with clinical manifestations in females. The clinical manifestations of patients with the same mutation are heterogeneous, and the correlation between gene mutation and enzyme activity or clinical manifestation is weak.

Objective To compare the analgesic effect, duration and incidence of adverse reactions of liposome bupivacaine (LB) and bupivacaine hydrochloride after intercostal nerve block in single-port thoracoscopic lung surgery. Methods In Department of Thoracic Surgery of the First Affiliated Hospital of Xinxiang Medical University between September 2023 and March 2024, 228 patients who needed to undergo thoracoscopic lung surgery were selected and divided into two groups by random number table method: a group B with bupivacaine hydrochloride (n=118), and a group LB with LB (n=110). Intraoperative intercostal nerve block was performed under endoscopy, and the time of first use of analgesic drugs after surgery, cumulative use of opioids 72 h after surgery, incidence of postoperative nausea and vomiting, length of stay and other indicators were evaluated and recorded. Results Visual analogue scale (VAS) scores at 4 h, 8 h, 12 h, 24 h, 48 h and 72 h in the LB group were significantly lower than those in the group B (P<0.05). The total number of activities within 48 h after surgery in the group B was significantly lower than that in the LB group (P<0.05), and the postoperative hospitalization stay in the LB group was shorter than that in the group B, but the difference was not statistically significant. There was no statistical difference between the two groups in postoperative adverse reactions. Conclusion Intercostal nerve block with LB during single-port thoracoscopic lung surgery can significantly reduce postoperative pain, improve quality of life, and promote recovery of the patients. It is worthy of clinical application.
