Objective: To establish the dynamic treatment strategy of Chinese medicine(CM) for metastatic colorectal cancer(m CRC) by machine learning algorithm, in order to provide a reference for the selection of CM treatment strategies for m CRC. Methods: From the outpatient cases of m CRC in the Department of Oncology at Xiyuan Hospital, China Academy of Chinese Medical Sciences, 197 cases that met the inclusion criteria were screened. According to different CM intervention strategies, the patients were divided into 3 groups: CM treatment alone, equal emphasis on Chinese and Western medicine treatment(CM combined with local treatment of tumors, oral chemotherapy, or targeted drugs), and CM assisted Western medicine treatment(CM combined with intravenous regimen of Western medicine). The survival time of patients undergoing CM intervention was taken as the final evaluation index. Factors affecting the choice of CM intervention scheme were screened as decision variables. The dynamic CM intervention and treatment strategy for m CRC was explored based on the cost-sensitive classification learning algorithm for survival(CSCLSurv). Patients' survival was estimated using the Kaplan-Meier method, and the survival time of patients who received the model-recommended treatment plan were compared with those who received actual treatment plan. Results: Using the survival time of patients undergoing CM intervention as the evaluation index, a dynamic CM intervention therapy strategy for m CRC was established based on *** CM intervention strategies for m CRC can be selected according to dynamic decision variables, such as gender, age, Eastern Cooperative Oncology Group score, tumor site, metastatic site, genotyping, and the stage of Western medicine treatment at the patient's first visit. The median survival time of patients who received the modelrecommended treatment plan was 35 months, while those who receive the actual treatment plan was 26.0 months(P=0.06). Conclusions:

Objective Brain microvascular endothelial cells (BMECs) were found to shift from their usually inactive state to an active state in ischemic stroke (IS) and cause neuronal damage. Ginsenoside Rb1 (GRb1),a component derived from medicinal plants,is known for its pharmacological benefits in IS,but its protective effects on BMECs have yet to be explored. This study aimed to investigate the potential protective effects of GRb1 on BMECs. Methods An in vitro oxygen-glucose deprivation/reperfusion (OGD/R) model was established to mimic ischemia-reperfusion (I/R) injury. Bulk RNA-sequencing data were analyzed by using the Human Autophagy Database and various bioinformatic tools,including gene set enrichment analysis (GSEA),Gene Ontology (GO) classification and enrichment analysis,Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway analysis,protein-protein interaction network analysis,and molecular docking. Experimental validation was also performed to ensure the reliability of our findings. Results Rb1 had a protective effect on BMECs subjected to OGD/R injury. Specifically,GRb1 was found to modulate the interplay between oxidative stress,apoptosis,and autophagy in BMECs. Key targets such as sequestosome 1 (SQSTM1/p62),autophagy related 5 (ATG5),and hypoxia-inducible factor 1-alpha (HIF-1α) were identified,highlighting their potential roles in mediating the protective effects of GRb1 against IS-induced damage. Conclusion GRbl protects BMECs against OGD/R injury by influencing oxidative stress,apoptosis,and autophagy. The identification of SQSTM1/p62,ATG5,and HIF-1α as promising targets further supports the potential of GRb1 as a therapeutic agent for IS,providing a foundation for future research into its mechanisms and applications in IS treatment.

本文提出了一种生物物理经济学思想的碳排放权价值区间测算模型,使用温室气体环境容量价值解释碳排放权内在价值,以区别于使用企业边际减排成本或一级、二级市场价格等博弈结果的解释方法。虽然气候与经济动态综合模型(DICE模型)使用碳排放的社会成本(SCC)概念部分地实现了这个目标,但如果模型经历“排放—碳循环—气候变化—经济损失”的传导后对贴现率过于敏感,那么结果可能会包含较大的主观性。本文首先研究温室气体环境容量的价值形成过程,通过概率分布描述所有影响碳排放权价值的因素;其次使用蒙特卡洛方法对这些因素进行10000次试验,最终得到碳排放权价值概率分布和模型的敏感性分析结果。本文还提出了碳排放权参照价格模型,用于评估每单位碳排放应为本国环境容量生产以及国际碳机制对本国的货币损失所支付的货币量。参照价格是符合《巴黎协定》中“公平以及共同但有区别的责任和各自能力原则”的理论碳价,考虑了不同国情。本文的模型计算完全根据中国实际情况获得关键参数和数据,为中国碳市场健康发展以及气候变化谈判提供理论依据。
