Natural products (NPs) are an important source of new drugs for the treatment of stroke. Identifying cellular targets for bioactive molecules is a major challenge and critical issue in the development of new drugs for stroke. Small-molecule probes play a unique role in target discovery. However, drawbacks to these probes include non-specificity, unstable activity, and difficulty in synthesis. Small-molecule probes based on NPs at least partially compensate for these shortcomings. NPs feature rich chemical and structural diversity, biocompatibility, and unique biological activities. These features could be exploited to provide new ideas and tools for target discovery. Small-molecule probes based on NPs provide a precise and direct search for interacting protein targets of NPs-active small molecules. This review explores the properties of small-molecule probes based on NPs and their applications in mechanistic studies of stroke and other diseases. We hope that this review will bring new perspectives to the mechanistic study of NPs-active small molecules and accelerate the translation of these ingredients into drug candidates for the treatment of stroke.

AIM: To analyze and screen influencing factors of diabetic patients complicated with retinopathy, and establish and validate prediction model of nomogram.METHODS: A total of 1 252 patients from the Diabetes Complications Early Warning Dataset of the National Population Health Data Archive(PHDA)between January 2013 to January 2021 were selected and randomly divided into a modeling group(n=941)and a validation group(n=311). Univariate analysis, LASSO regression and Logistic regression analysis were used to screen out the influencing factors of diabetic retinopathy, and a nomogram prediction model was established. The receiver operating characteristic curve, Hosmer-Lemeshow test and calibration curve were used to evaluate the model. The clinical benefit was evaluated by the decision curve analysis(DCA).RESULTS: Age, hypertension, nephropathy, systolic blood pressure(SBP), glycated hemoglobin(HbA1c), high-density lipoprotein cholesterol(HDL-C), and blood urea(BU)were the influencing factors of diabetic retinopathy. The area under the curve(AUC)of the modeling group was 0.792(95%CI: 0.763-0.821), and the AUC of the validation group was 0.769(95%CI: 0.716-0.822). The Hosmer-Lemeshow goodness of fit test and calibration curve suggested that the theoretical value of the model was in good agreement(modeling group: χ2=14.520, P=0.069; validation group: χ2=14.400, P=0.072). The DCA results showed that the threshold probabilities range was 0.09-0.89 for modeling group and 0.07-0.84 for the validation group, which suggested the clinical net benefit was higher.CONCLUSION: This study constructed a risk prediction model including age, hypertension, nephropathy, SBP, HbA1c, HDL-C, and BU. The model has a high discrimination and consistency, and can be used to predict the risk of diabetic retinopathy in patients with diabetes.

Objective: To assess the efficacy and safety of combining traditional Chinese medicine (TCM), specifically Chinese herbal medicine (CHM), with Western medicine (WM), compared to WM alone to treat breast cancer endocrine therapy-related osteoporosis (BCET-OP) by meta-analysis. Methods: Thirty-eight randomized controlled trials involving 2170 participants were analyzed. Eight databases were searched for articles published between inception and December 2023. Quality assessment was performed using the Risk of Bias 2 tool. Results: Significant increases were observed in the TCM-WM group in lumbar vertebrae bone mineral density (BMD) (P < .001, mean difference (MD) = 0.07, 95% confidence interval (CI): 0.06 to 0.08), lumbar vertebrae T-score (P = .0005, MD = 0.21, 95%CI: 0.09 to 0.33) and collum femoris BMD (P = .01, MD = 0.10, 95%CI: 0.02 to 0.19). No significant difference was observed between the groups in the collum femoris T-score and estradiol levels. Bone gla-protein levels were significantly increased in the TCM-WM group (P = .0002, MD = 0.52, 95%CI: 0.25 to 0.79). Beta-CrossLaps decreased significantly in the TCM-WM group (P = .0008, MD = −0.10, 95%CI: −0.16 to −0.04). No significant difference was observed between the TCM-WM and WM groups in alkaline phosphatase, in procollagen type I N-terminal propeptide, and in the Kupperman index. The visual analog score (VAS) was decreased in the TCM-WM group compared to the WM group (P < .001, MD = −1.40, 95%CI: −1.94 to −0.87). No significant difference in adverse events was observed between the two groups. Conclusion Combining CHM with WM in patients with BCET-OP significantly improved BMD, T-score, and certain bone turnover markers and reduced the VAS score, indicating potential benefits for bone health and related pain. Adverse event analysis revealed no differences between the groups, supporting the feasibility of the combination therapy. However, further research, particularly in diverse populations, is required.

Objective:To clarify the effect of the reform of Sichuan medical association on the coordinated development of medical re-sources supply and regional economy,and provide a basis for continuing to promote the coordinated development.Methods:Based on the panel data of 18 prefecture-level cities and 3 autonomous prefectures in Sichuan Province from 2009 to 2021,the medical resources invest-ment and economic development level of each city(state)in Sichuan Province were calculated by entropy weight method.Through the cou-pled coordination model,the degree of coordinated development was measured.The discontinuous time series model is used to measure the impact of the implementation of the medical association policy on the degree of coordinated development.Results:From 2009 to 2021,the supply of medical resources in Sichuan Province showed an overall upward trend,but the characteristics of the first concentration were ob-vious.In 2021,the coupling degree between medical resources investment and economic development in Sichuan Province is high(0.808),but the coupling coordination degree was still in a barely coordinated stage(0.540).The implementation of the reform of medical associa-tion effectively promoted the coordinated development of medical resource supply and regional economy.Conclusion:Local governments need to further strengthen the building of medical associations.By making long-term medical resources planning and exploring the role of digital technology in the medical field,it will further promote the expansion and balanced distribution of high-quality medical resources.
