ObjectiveThe development trend and knowledge structure of the research on human use experience （HUE） of traditional Chinese medicine （TCM） were systematically reviewed， and the core challenges and future directions were identified. This study aims to provide reference for the construction of a scientific and feasible research and development framework and evidence transformation system. MethodsLiterature related to "human use experience" published from January 1， 2019 to July 31， 2025 was retrieved from the China National Knowledge Infrastructure （CNKI）， Wanfang， China Science and Technology Journal Database （VIP）， and PubMed databases. Bibliometric visualization was conducted using Excel， VOSviewer， and CiteSpace， followed by in-depth reading and thematic summarization of core literature. ResultsA total of 181 papers were included for bibliometric analysis， with 45 articles used for in-depth thematic mining. The analysis showed that the number of publications on HUE research has increased in a stepwise manner over the past five years. Yang Zhongqi （24 times） was the core of the author network， the journal with the highest number of publications was China Journal of Chinese Materia Medica， the institutions publishing the most articles were mainly research institutions， regulatory agencies， hospitals， and universities， high-frequency keywords included "new TCM drugs"， "real-world studies"， and "clinical comprehensive evaluation"， keyword clustering analysis formed three major clusters： Policy orientation， application fields， and methodological approaches. Thematic analysis reveals that HUE-based evaluation should be integrated throughout the research and development process， encompassing three dimensions： TCM theory， clinical value， and pharmaceutical fundamentals， with toxic herbs and compatibility contraindications being key foci. Data collection primarily relies on empirical data， while real-world data constitute the primary source for clinical research， with efficacy and safety as the shared core. Data management emphasizes quality control and statistical analysis； however， the management of bias and confounding remains a critical bottleneck in evidence transformation. In practice， HUE-based approaches have successfully supported the registration and evaluation of multiple categories of new TCM drugs. ConclusionThe research on HUE of TCM has formed a policy-driven pattern characterized by， rapid development and close link with regulatory practice. A technical framework covering the whole chain of research and development has been constructed with clinical value as the core， which provides methodological basis and strategy reference for the scientific transformation of HUE of TCM from "experience" to "evidence".

Objective:To explore the effect of carboxylated polyamidoamine (PAMAM-COOH) in combination with magnesium ions on the remineralization ability of amorphous calcium phosphate (ACP) in inducing remineralization of dentin collagen fibers in a 50% ethanol solution.Methods:Forty-five intact third molars extracted for impaction reasons were obtained from the College & Hospital of Stomatology, Guangxi Medical University. Two types of demineralized dentin specimens were prepared: ①Fully demineralized dentin ( n=30), specimens were immersed in 17% ethylenediaminetetraacetic acid (EDTA) (pH=7.4) at room temperature for 14 days with daily solution refreshment; ②Partially demineralized dentin ( n=15), specimens were treated with 37% phosphoric acid gel (Ultra-Etch, Ultradent) for 15 seconds followed by thorough rinsing with deionized water. Three remineralization groups were established for demineralized dentin treatment: ①Control group, 50% ethanol solution; ②ACMP group, 50% ethanol solution containing amorphous magnesium calcium phosphate (ACMP); ③PAMAM-COOH/ACMP group, 50% ethanol solution incorporating carboxylated polyamidoamine dendrimer-modified ACMP (PAMAM-COOH/ACMP). The chemical composition of remineralization solutions was analyzed by Fourier-transform infrared spectrum (FTIR). The morphology and particle size distribution of nanoparticles were characterized using transmission electron microscope (TEM). The fully demineralized dentin specimens were treated with three different remineralization solutions (37 ℃ for 7 days) respectively. The mineralization of the dentin collagen fibers surface was observed using scanning electron microscope (SEM) and the distribution of minerals inside and outside the collagen fibers was examined by using TEM. The partially demineralized dentin specimens were treated with fluorescence-labeled remineralization solutions (37 ℃ for 7 days) respectively, followed by analysis using confocal laser scanning microscopy (CLSM) to quantitatively evaluate the penetration depth of the mineralization agents. Results:FTIR analysis confirmed the presence of characteristic absorption peaks corresponding to phosphate (PO 43-) groups, carbon-nitrogen bonds, and amide linkages in the PAMAM-COOH/ACMP nanocomposite. TEM observed that the PAMAM-COOH/ACMP nanoparticles exhibited an average particle size of (36.85±8.02) nm in an amorphous state. SEM observation indicates continuous mineral deposition on dentin collagen fibers in the PAMAM-COOH/ACMP group, while no mineral deposition in the control group and only minimal deposition in the ACMP group. TEM showed no mineral deposition inside or outside the collagen fibers in the control group, only external mineral deposition in the ACMP group, and high-density mineral deposition both inside and outside the fibers in the PAMAM-COOH/ACMP group. CLSM analysis revealed a statistically significant difference ( P<0.05) in the depth of mineralized substances entering dentin tubules between ACMP group and PAMAM-COOH/ACMP group. Conclusions:The remineralization system of 50% ethanol solution incorporating PAMAM-COOH/ACMP successfully achieved the internal and external mineralization of demineralized dentin collagen fibers.

Salvia miltiorrhiza Bunge （Lamiaceae） is a medicinal plant widely used in Traditional Chinese Medicine for treating cardiovascular and cerebrovascular diseases. Chloroplasts are double-membrane-bound, chlorophyll-containing organelles and responsible for photosynthesis in plant cells. The structural information of chloroplast genomes serves as the foundation for precise exogenous gene insertion, site selection, and chloroplast genome modification. In this study, a comprehensive analysis and comparison of 125 chloroplast genomes from S. miltiorrhiza and 76 congeneric species were conducted, focusing on sequence characteristics, codon usage bias, simple sequence repeats （SSRs）, contraction/expansion of chloroplast genome boundaries, and phylogenetic relationships, which could provide a theoretical foundation for advancing chloroplast genetic engineering, genetic diversity analysis, molecular breeding, and species identification within the Salvia genus.

Objective To investigate the relationship of triglyceride-glucose(TyG)index and atherogenic index of plasma(AIP)with positive remodeling of coronary arteries in elderly coro-nary heart disease(CHD)patients with concomitant type 2 diabetes mellitus(T2DM).Methods A total of 120 elderly CHD patients with concomitant T2DM admitted to our department from January 2022 to June 2023 were continuously recruited,and according to the remodeling index,they were divided into positive remodeling group(47 cases)and non-positive remodeling group(73 cases).The clinical data were compared between the two groups.Multivariate logistic analysis was used to identify the risk factors for positive remodeling of coronary artery.Spearman correla-tion analysis was employed to analyze the correlation of TyG and AIP with positive remodeling.ROC curve was plotted to analyze the predictive value of TyG and AIP for the remodeling.Results The positive remodeling group had larger ratio of smoking,higher TG and HbA1c levels,and in-creased TyG index and AIP,but lower HDL-C and blood calcium levels than the non-positive re-modeling group(P＜0.05,P＜0.01).Univariate logistic regression analysis showed that smoking,TG,HDL-C,HbA1c,blood calcium,TyG and AIP were risk factors for positive coronary artery remodeling in elderly patients with CHD and T2DM(P＜0.05,P＜0.01).Multivariate logistic re-gression analysis showed that TyG index(OR=7.253,95％CI:2.458-13.364,P=0.035)and AIP(OR=6.017,95％CI:2.205-12.025,P=0.030)were independent risk factors for positive coronary artery remodeling in elderly patients with CHD and T2DM(P＜0.05).The AUC value of TyG index and AIP in predicting positive coronary artery remodeling in elderly CHD patients with T2DM was 0.783 and 0.766,respectively,and the value of their combination in the prediction was 0.868,which was significantly better than the indicator alone(P＜0.05).Conclusion TyG in-dex and AIP are closely associated with positive coronary artery remodeling in elderly CHD pa-tients with T2DM,and can be used as effective indicators in the prediction of positive remodeling,which is of great significance for early clinical identification of high-risk patients and formulation of individual intervention strategies.
