In this study , 4116 traditional Chinese medicine ( TCM ) prescriptions of 994 outpatients of gastric
cancer from the Jiangsu Provincial Hospital of Traditional Chinese Medicine were analyzed with the use of Clinical Research Information Sharing System and the data mining method of scale-free networks . The core drugs and compatibility were visually displayed on diagrams which revealed the characteristics of gastric cancer treatment with TCM prescriptions in this hospital with high credibility . This method has certain meaning and value for the study of TCM prescriptions .
2.Effects on apoptosis and cell cycle of RA in HT29 cells
The Journal of Practical Medicine 2017;33(23):3858-3863
Objective To investigate the effects of Raddeanin A(RA)on apoptosis and cell cycle of hu-man colon cancer HT29 cells,and discuss the possible mechanism.Methods Different concentration of RA 1,2, 4,8,16μmol/L disposed HT29 cells 12,24,48 hour,3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bro-mide(MTT)assay was used for the cell proliferation;Hoechst33258 staining was performed to observe the effects of RA on apoptosis morphology;Flow cytometry(FCM)was devoted to calculate apoptosis rate and detect cell cycle;The expression of Cleaved-caspase-3,Cleaved-PARP,CyclinB,CDK1 proteins and other proteins were tested by Western blot(WB). Results RA could inhibit the proliferation of HT29 cells,and associated with concentration and time(P<0.05);The IC50of 12 h,24 h,48 h were(9.31 ± 0.63)μmol/L,(4.88 ± 1.02)mol/L,(3.60 ± 0.89) μmol/L.The nucleus pycnosis,fracture were detected by Hochest33258 staining,RA induced apoptosis in HT29 cells;Western blot(WB)assay showed that the expression of Cleaved-caspase-3,Cleaved-PARP rised.HT29 cells were arrested at the period of G2/M,and the CyclinB,CDK1 proteins down-regulated.WB result showed that PI3K, AKT proteins up-regulated,while p-PI3K,p-AKT protein down-regulated.Conclusion RA can inhibit the prolifer-ation of colon cancer HT29 cells and its mechanism is probably by regulating the PI3K/AKT signaling pathways which through inducing apoptosis and blocking the cell cycle.

Objective To explore raddeanin A(RA) inhibiting the proliferation of HCT116 cells and its related mechanism.Methods The MTT method was used to observe the RA inhibition on the proliferation of gastric cancer cells HCT116.Flow cytometry was used to detect the RA effects on cell apoptosis.Transmission electron microscope(TEM) was used to observe RA induced autophagy.Western blot was used to test expression of apoptosis and autophagy related proteins.Results RA could significantly inhibit the proliferation of HCT16 cells with concentration and time dependence;double layer membrane of autophagosome was detected by TEM;FCM showed that RA induced apoptosis in HCT116 cells,moreover the apoptosis rate was increased with the concentration increase;Western blot showed that the expression of autophagy related proteins(Beclin1 and LC3) was increased,the expression of apoptosis inhibition protein Bcl-2 was decreased.On the contrary,the expression of apoptosis promotion proteins(Bax,Cleaved-caspase-3,Cleaved-PARP) was increased,the expression of mTOR protein in the mTOR signal pathway was increased,while the p-mTOR protein expression was decreased.When the mTOR pathway inhibitor rapamycin(RAPA) was added to cells,Beclin-1,LC3,Cleaved-caspase-3,Cleaved-PARP proteins were increased,and apoptosis rate was also increased.Conclusion RA can inhibit the proliferation of HCT116 cells and can induce cellular autophagy and apoptosis,its mechanism may be realized by regulating the mTOR signal pathway.

Objective To compare the efficacy and safety of vedolizumab(VDZ)and infliximab(IFX)for moderate to severe ulcerative colitis(UC)patients through a multicenter retrospective cohort study.Methods All patients with moderate to severe UC who were naive to biologic agents and treated with IFX or VDZ for at least 14 weeks at 3 hospitals in Southwest China between January 2021 and January 2023 were retrospectively enrolled.The efficacy evaluation indicators,including steroid-free clinical remission rates,clinical remission rates and endoscopic remission rates at weeks 14 and 52 were compared between the 2 groups.The occurrence of adverse events during treatment were recorded.Taking whether mucosal healing could be achieved after 14 and 52 weeks of treatment as the dependent variable,firstly,univariate analysis was performed to analyze the risk factors affecting mucosal healing at weeks 14 and 52,and then multivariate logistic regression analysis was applied to identify the independent risk factors of mucosal healing at the 2 time points.Results A total of 151 patients with moderate to severe UC were included,after propensity score matching(PSM),each group included 57 patients.There were no significant differences in the steroid-free clinical remission rate and clinical remission rate between the 2 groups at weeks 14 and 52(P>0.05).The endoscopic remission rate at week 14 was significantly higher in the VDZ group than the IFX group[40.4%(23/57)vs 22.8%(13/57),P=0.044],but no such difference was observed at week 52[64.5%(20/31)vs 59.5%(22/37),P=0.669].Multivariate logistic regression analysis showed that left-sided disease(E2)[vs pancolitis(E3)](OR=0.46,95%CI:0.21~0.98,P=0.045)was independent risk factor for mucosal healing at week 14 and a disease duration ≥36 months(OR=0.25,95%CI:0.09~0.66,P=0.005)was independent risk factor for mucosal healing at week 52.No statistical difference was observed in the incidence of adverse events between the 2 groups(1.8%vs 7.0%,P=0.360).Conclusion VDZ and IFX have similar efficacy and safety,and both can be used as first-line options for patients with moderate to severe UC.
