Abstract
目的 采用网络药理学的方法探讨半夏泻心汤"异病同治"慢性萎缩性胃炎及失眠的共同作用机制.方法 通过中药系统药理学数据库(traditional Chinese medicine systems pharmacology database,TCMSP)筛选半夏泻心汤的主要活性成分并预测其潜在作用靶点,利用GeneCards、OMIM、TTD、DrugBank和DisGeNET数据库搜集慢性萎缩性胃炎和失眠相关疾病靶点.将药物靶点与疾病靶点取交集获取共有靶点,并将其导入Cytoscape软件绘制"半夏泻心汤成分-共有靶点"网络图.运用STRING数据库获得共有靶点蛋白互作网络关系,并导入Cytoscape进行拓扑分析及可视化.通过Metascape数据库对共有靶点进行基因本体(gene ontology,GO)富集分析和京都基因与基因组百科全书(Kyoto encylopedia of genes and genomes,KEGG)通路富集分析.结果 筛选后得到半夏泻心汤"异病同治"慢性萎缩性胃炎及失眠的主要活性成分138个,作用于58个共同靶点.GO功能富集分析涉及生物学过程4508个、分子功能407个、细胞组成347个,KEGG通路富集分析共获得187条信号通路,主要涉及晚期糖基化终末产物-糖基化终末产物受体(AGE-RAGE)信号通路、T细胞受体信号通路、辅助性T细胞17(Th17)分化、缺氧诱导因子-1(HIF-1)信号通路、血管内皮生长因子(VEGF)信号通路、核因子-κB (NF-κB)信号通路、癌症的途径等通路,表明半夏泻心汤可能通过调节炎症反应、免疫功能、氧化应激、血管生成等发挥对慢性萎缩性胃炎和失眠的共同治疗作用.结论 半夏泻心汤"异病同治"慢性萎缩性胃炎和失眠涉及多种成分、多个靶点以及多条通路,可为接下来的实验研究及临床应用提供参考.

- Pretraining has recently greatly promoted the development of natural language processing (NLP)
- We show that M6 outperforms the baselines in multimodal downstream tasks, and the large M6 with 10 parameters can reach a better performance
- We propose a method called M6 that is able to process information of multiple modalities and perform both single-modal and cross-modal understanding and generation
- The model is scaled to large model with 10 billion parameters with sophisticated deployment, and the 10 -parameter M6-large is the largest pretrained model in Chinese
- Experimental results show that our proposed M6 outperforms the baseline in a number of downstream tasks concerning both single modality and multiple modalities We will continue the pretraining of extremely large models by increasing data to explore the limit of its performance
