Xing xiao Pills.Finally,Autodock was used for molecular docking verification.3 Experimental study:(1)In vivo experiment:The Lewis lung cancer xenograft mouse model was constructed and divided into Xing xiao Pill low-dose,medium-dose,high-dose,and cisplatin groups.Each group was given fourteen days of intragastric administration,and measuring the mouse tumor tissue every three days,including their volume and visceral coefficient.Besides,HE was responsible for observing the pathological changes of tumor tissue in each group,WB were in charge of detecting the effect of Xing xiao Pill regulating PI3K/AKT/mTOR signaling pathway,transcriptome sequencing was performed on the tumor tissues of mice in the highdose intervention and control groups of Xing xiao Pills,which is to analyze the differential genes,main biological functions and signaling pathways of Xing xiao Pills on lung cancer mice,and integrated with the results of network pharmacology research.(2)In vitro experiments:CCK-8,cell apoptosis,cell cycle and transwell test were in charge of detecting the inhibition rate,the effects on apoptosis and cycle and the consequence on the migration of A549 cells.Oil red O staining,TC,TG,HDL-C,LDL-C and free fatty acid kits were responsible for checking the outcome on lipid droplets,measuring the assay of TC,TG,LDL-C,HDL-C and free fatty acid in A549 cells intervened by Xing xiao Pills.Otherwise,WB were responsible for evaluating the results of A549 cells on the protein contents of PI3K/AKT/mTOR/SREBP1 pathway and FASN contents in A549 cells.Result:1 Observational study of clinical efficacy:(1)Efficacy evaluation:Traditional Chinese medicine syndrome score showed that compared with conventional treatment alone,after taking Xing xiao Pill orally for two weeks,the total traditional Chinese medicine syndrome score had a markedly decrease,and symptoms such as aversion to cold,cold extremities and other symptoms were significantly reduced;After one month,the treatment group significantly improved the total score of traditional Chinese medicine syndromes,relieved symptoms such as fear of cold,chills,constipation,chest tightness and chest pain,dark purple tongue,and the curative effect was better than that of the control group.Besides,the effective rate of traditional Chinese medicine syndrome was significantly improved in the treatment group.Quality of Life Scale score found that after two weeks of treatment,the overall healthy living status of treatment group was better than that of those who only received conventional treatment,moreover,after one month,the overall healthy living status,symptoms and specific symptom scores were all obtained improve and enhance.WHO anticancer drug acute and subacute side effects showed that after two weeks,compared to the control group,the constipation and pain of the treatment group were improved,and the other targets did not change significantly.(2)Safety evaluation:There were no obvious variety diversity in stool routine,blood,coagulation,urine,biochemistry and electrocardiogram examinations between the two groups during the trial.2 Network pharmacology research:The main pathways of Xing xiao Pill in the treatment of lung cancer included PI3K/AKT/mTOR,MAPK,MicroRNA,etc.The core targets were AKT1,SIRT7,MDM2,mTOR,etc.3 Experimental study:(1)In vivo experiment:Xing xiao Pill high-dose and cisplatin group could inhibit tumor growth in mice with lung cancer,and could make tumor tissue necrotic.Moreover,it could down-regulate the protein content of p-AKT.Transcriptome sequencing showed that the main signaling pathways of Xing xiao Pill in the treatment of lung cancer mice involved estrogen signaling pathway,PI3K/AKT/mTOR,PPAR,AMPK,aerobic glycolysis,fatty acid metabolism and other pathways.Integrated with the results of network pharmacology,they jointly focused on the PI3K/AKT/mTOR pathway and lipid metabolism way.(2)In vitro experiments:The IC50 group of Xing xiao Pills water extract made a role in inhibiting the proliferation and migration of A549 cells,abducted their apoptosis,and arrested the cell cycle in S phase.It could cut down lipid droplets,TC,LDL-C,TG and free fatty acid in cells.The mechanism involved is that it can down-regulated the protein expression levels of p-PI3K,AKT,p-AKT,p-mTOR,SREBP1 and
