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.

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.

Objective:To explore the application value of a novel bag respirator assisted ventilation device in postoperative transport under general anesthesia with laryngeal mask.Methods:A total of 133 patients in postoperative transport who underwent elective bron-choscopy or treatment under general anesthesia with laryngeal mask in the First Affiliated Hospital of Chongqing Medical University,from June to August 2023 were selected.The patients were randomly divided into control group(n=65)and experimental group(n=68),and received manual bag respirator assisted ventilation and the novel bag respirator assisted ventilation device during their postop-erative transport,respectively.The pulse oxygen saturation(SpO2),heart rate(HR),and ventilation frequency during transport,trans-port duration,and transport-related adverse events were compared between the two groups.Results:The difference in SpO2 was signifi-cant when comparing the two groups(Fbetween groups=18.588,P<0.001),and the SpO2 of patients in the experimental group was signifi-cantly higher than that of patients in the control group during and after transport(P<0.001).The difference in HR was not significant when comparing the two groups(Fbetween groups=0.089,P=0.766),but it was significant between the control and experimental groups before and after transport(Ftime point=12.430,P<0.001);the HR in the con-trol and experimental groups before and during transport was signifi-cantly lower than that after transport(all P<0.001).The ventilation frequency of the experimental group was significantly lower than that of the control group(P<0.001).The transport duration in the ex-perimental group was longer than that in the control group,but the difference was not significant(P=0.987).Both groups successfully completed the trial without transport-related adverse events and achieved safe transport.Conclusion:Compared with the manual bag respirator assisted ventilation technology,the novel bag respirator assisted ventilation device for respiratory support during postopera-tive transport in patients under general anesthesia with laryngeal mask is more able to reduce the impact on the patient's hemodynam-ics and conducive to the maintenance of the patient's stable vital signs,showing a good clinical application value.It is expected to be a safe and effective ventilation method during intrahospital transport in some patients under general anesthesia.

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.

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.

Objective:Investigation of the relationship between variant angina pectoris syncope and coronary artery spastic targeted location, arrhythmias, and coronary artery stenostic lesion.Methods:This study combined retrospective and prospective registry approaches. Data were sourced from the case database of Henan province "Multicenter Clinical Observation Study of Variant Angina Pectoris". A total of 507 patients with variant angina pectoris who had complete records from June 1980 to December 2022 were consecutively enrolled. Select patients among them who experienced syncope, and analyze the target vessel sites of coronary artery spasm, arrhythmias during variant angina pectoris attacks, and the degree of stenosis in coronary artery lesions.Results:Among 507 variant angina pectoris patients, 88 experienced syncope. Age was (53.9±9.7) years and 66 patients (75.0%) were male. Forty patients (45.5%, 40/88) were aged 50-59 years. The incidence of syncope in variant angina pectoris caused by left anterior descending artery (LAD) spasm, right coronary artery (RCA) spasm, and multivessel coronary artery spasm was 7.4% (15/202), 22.7% (42/185), and 23.6% (25/106), respectively. The latter two were significantly higher than those in the LAD group ( P all<0.05). Among 77 patients with variant angina pectoris syncope, definitive electrocardiogram recordings were available during syncope episodes. All patients exhibited arrhythmias during syncope: 34 cases involved tachyarrhythmias and 43 cases involved bradyarrhythmias. The incidence of rapid arrhythmias in patients with LAD, RCA, and multi-vessel spasm syncope was 72.7% (8/11), 24.3% (9/37), and 54.2% (13/24), respectively, with P<0.05 for the first two. Bradyarrhythmias occurred in 27.3% (3/11) of LAD, 75.7% (28/37) of RCA, and 45.8% (11/24) of multivessel coronary artery spasm syncope cases, with the first two showing P<0.05. Coronary angiography analysis of 56 syncope patients revealed target vessel locations and stenosis severity: 12 patients had LAD lesions and 41 had RCA lesions, stenosis ≥50% occurred in 66.7% (8/12) and 43.9% (18/41) of these lesions, respectively ( P>0.05). Conclusions:Variant angina pectoris syncope predominantly affects middle-aged males. Bradyarrhythmias triggered by RCA spasm are a common cause, while the incidence of syncope shows no significant correlation with the degree of coronary artery stenostic lesion, whether in the LAD or the RCA.

Infectious disease animal models serve as indispensable tools for understanding the transmission patterns,pathogenesis,and anti-infective medicine.During the preparation and application of infectious animal disease models,situations inevitably arise that violate animal welfare and ethics,such as animal pain,suffering,and distress.Considering the biosafety factors,animal mortality is still used as the experimental endpoint in most experiments on infectious animals,which poses extremely high requirements for animal welfare and ethics.It is imperative to establish guiding principles or norms for the welfare and ethics of infectious animal experiments.Based on the fundamental principles of the welfare and ethics of experimental animals,this paper explores the special welfare and ethical requirements in infectious animal experiments.It emphasizes that infectious animal experiments should fully consider the balance among the scientific objectives of the research plan,animal welfare and ethics,and occupational health and safety of personnel.Based on literature research and comparative analysis of the welfare and ethical requirements of conventional animal experiments,special welfare and ethics requirements for infectious animal experiments are proposed,including personnel requirements,experimental animal selection standards,living environment management and equipment,special care and veterinary care,and humane endpoints.Personnel are required to undergo effective biosafety training,and sufficient authority should be granted to the Institutional Animal Care and Use Committee(IACUC),veterinarians,and veterinary technicians to ensure the implementation of animal welfare and ethics practices.The selection of laboratory animals should fully consider the requirements of research objectives,welfare,ethics,and biosafety,with the susceptibility and body size of laboratory animals being the key concerns in high-level biosafety laboratories.It is also clarified that the humane endpoint is an indispensable element of welfare and ethics in infectious animal experiments.Environmental enrichment and special care are necessary guarantees for achieving animal welfare and ethics.Therefore,this study can serve as a reference for relevant work.

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.

This study aims to determine the nephrotoxic effects of 3-monochloropropanel-1,2-diol(3-MCPD)on female and male SD rats.A nephrotoxicity model was established by gavage of dif-ferent doses of 3-MCPD,and 80 SD rats were randomly divided into four groups:the control group(0 mg/kg 3-MCPD),low-dose group(15 mg/kg 3-MCPD),medium-dose group(30 mg/kg 3-MCPD),high-dose group(60 mg/kg 3-MCPD),with half female and half male.The body mass and food intake of the rats were recorded weekly,and the urine and blood and kidney tissues were col-lected after 28 consecutive days of gavage,and the blood erythrocyte count(WBC),white blood cell count(RBC),hemoglobin(HGB),erythrocyte-compaction-transfer-value(HCT),creatinine(CREA),serum urea nitrogen(BUN),and the indexes of blood phosphorus(P)and calcium(Ca)were detected;the level of kidney injury molecule(KIM-1)was measured by ELISA kit;the renal pathological changes was observed by histopathology method;and transcriptome sequencing was used to analyze differential genes in female and male rats.The results showed that 3-MCPD did not significantly affect the growth of male rats,but high doses significantly reduced the weight and food intake of female rats.The high-dose group of 3-MCPD caused a significant decrease in RBC,HGB,and HCT levels in both male and female rats,resulting in a significant increase in KIM-1 and P,and a significant decrease in Ca,but only a significant increase in CREA and BUN in female rats.Histopathology showed that in the high-dose group of male rats,only mild renal tubular dilation,epithelial cell edema,and clear tubular type were observed in the kidneys,while in female rats,a large number of renal sacs,clear tubular type,and interstitial inflammatory cells with fibrosis were observed in the kidneys.Transcriptome sequencing showed 1 712 differentially expressed genes in the high-dose group of female rats and 1 153 differentially expressed genes in the high-dose group of male rats.KEGG enrichment analysis showed that both male and female rats in the high-dose group experienced oxidative stress and cell apoptosis,but 3-MCPD may also participate in the process of kidney damage in females by inhibiting autophagy and inducing iron death pathways.The above results indicate that high-dose 3-MCPD has a more significant nephrotoxic effect on fe-male rats.
