[Objective]To explore the effect and the possible mechanism of the proteasome inhibitor MG132 on acute T lympho?blastic leukemia cells.[Methods]The influence of different concentrations of MG132 in the viability and proliferation of CCRF-CEM was measured by MTS. Apoptosis rates of CCRF-CEM treated by MG132 were determined by flow cytometry. After being exposed to MG132,the protein levels of FOXO3a in cytoplasm and nucleus were analyzed by Western blotting. qRT-PCR was applied to detect the mRNA of FOXO3a and Puma in cells treated by MG132. Then CCRF-CEM was stably transfected with antisense FOXO3a using Lentivirus infection. We further investigated the effects of MG132 in FOXO3a-shRNA cells and elucidated the mechanisms of FOXO3a and Puma.[Results]MG132 inhibits the proliferation of CCRF-CEM,but has no cytotoxicity in peripheral blood mononu?clear cells(PBMC). Cellular apoptosis was induced in cells treated with MG132. At mRNA level,MG132 had no influence on FOXO3a,but increased the expression of Puma. However,MG132 promoted the expression of both FOXO3a and Puma at protein level. Interestingly,the expression of FOXO3a increased very little in cytoplasm. In FOXO3a-shRNA cells the expression of FOXO3a and Puma decreased at protein level. FOXO3a's knockdown attenuated the proliferation inhibition mediated by MG132.[Conclusion]MG132 inhibits the proliferation and promotes to apoptosis of CCRF-CEM. One of the mechanism is that MG132 inhib? its the degradation of FOXO3a,and then activates FOXO3a/Puma pathway.

Objective To study the expression of peripheral blood lymphocyte P-glycoprotein(P-gp)and related impact factors in rheumatoid arthritis(RA)patients,and explore whether the periodic combination of methotrexate(MTX)or leflunomide(LEF)with cyclophosphamide(CTX)could reverse P-gpinduced drug resistance.Methods This study was a cross-sectional study.Forty-two RA patients were enrolled(15 cases in the primary untreatment group,while 27 cases in the treatment group).In the treatment group,patients were divided into the improvement group(12 patients)and the refractory group(15 patients)respectively according to their disease activity scores(DAS 28).According to the medication used,42 patients were divided into 3 groups:the monotherapy group(MTX or LEF),the MTX+LEF combination treatment group and MTX or LEF+CTX treatment group.The expression of peripheral blood lymphocyte P-gp in each group was detected by flow cytometry.T test,ANOVA,LSD test,Bonferroni test,x2 test and Pearson correlation analysis were used for statistical analysis with software 13.0.Results ① Mean relative fluore scence intensity(RFI)of P-gp was 2.0±0.7,2.9±1.0,3.5±1.4,5.0±2.0 respectively in healthy control group,the primary untreatment group,the improvement group and the refractory group,the difference was significant(F=7.955,P＜0.01).in multiple comparisons,the fluorescence intensity was higher in the primary untrea-tment group as compared to the healthy group,but the difference was not statistically significant(P=0.137);however,it was significantly higher in the refractory group as compared to the improvement group(P=0.013).② There was no correlation between the expression of P-gp in RA patients and sex,age of onset,disease duration or positive rate of RF.But the expression of P-gp was significantly correlated with ESR and DAS28(r=0.447,P=0.002;r=0.398,P=0.012).③ RFI of the P-gp group was 5.1±2.2,6.0±1.2,3.4±1.1 respectively in monotherapy group,MTX+LEF group and MTX/LEF+ CTX group(P＜0.05).The expression of P-gp was significantly lower in the MTX/LEF+CTX group as compared to the monotherapy group(P＜0.05),but higher in the MTX+LEF group(P＞0.05).Conclusion The expression of peripheral blood lymphocyte P-gp in RA is correlated with disease activity.The loss of efficacy in DMARDs is due to the enhanced expression of P-gp.Combination of methotrexate or leflunomide with cyclo-phosphamide reverses P-glycoproteininduced drug resistance.

The free membrane of Eudragit L100/S100 which is pH-sensitive, colon-specific was prepared by plane casting films. The film humidity, species and amount of plasticizers, the ratio of membrane material was investigated. The rate of membrane permeability and mechanical properties were used as indicators of orthogonal experiment, and its related properties were studied. The results show that the mechanical properties of the membrane and phragmoid capacity are the best when 30% TEC was used as plasticizer; the ratio of membrane material have little effect on the rate of membrane permeability and mechanical properties. By adjusting the species and amount of plasticizers, the ratio of Eudragit L100/S100, the free membrane which is colon-specific can be obtained.
