Objective To observe the effect and safety of the aversion therapy with furazolidone on patients with alcohol dependence.Methods 90 patients with alcohol dependence were randomly divided into the aversion therapy group and the control group with 45 cases in each group. The cases of the aversion therapy group were treated by aversion therapy with furazolidone and those of the control group were treated with routine therapy. The changes of the blood pressure, pulse and respiratory rate before and after drinking were observed and the rate of successful abstinence in one year was investigated.Results The effect of the aversion therapy group treated with furazolidone was significantly better than that of the control group ( P<0.05). The aversion therapy was safe.Conclusion The aversion therapy with furazolidone is more effective and safe.

OBJECTIVETo study the effect of glycolysis inhibitor 3-bromopyruvate (3-BrPA) in inducing apoptosis of human breast carcinoma cells SK-BR-3 and the possible mechanism.

METHODSMTT assay was used to detect the growth inhibition induced by 3-BrPA in breast cancer cells SK-BR-3. The apoptotic cells were detected by flow cytometry with propidium iodide (PI). ATP levels in the cells were detected by ATP assay kit, and DHE fluorescent probe technique was used to determine superoxide anion levels; the mitochondrial membrane potential was assessed using JC-1 staining assay.

RESULTSMTT assay showed that the proliferation of SK-BR-3 cells was inhibited by 3-BrPA in a time- and concentration-dependent manner. Exposure to 80, 160, and 320 µmol·L(-1) 3-BrPA for 24 h resulted in cell apoptosis rates of 6.7%, 22.3%, and 79.6%, respectively, and the intracellular ATP levels of SK-BR-3 cells treated with 80, 160, 320 µmol·L(-1) 3-BrPA for 5 h were 87.7%, 60.6%, and 23.7% of the control levels. 3-BrPA at 160 µmol·L(-1) increased reactive oxygen levels and lowered mitochondrial membrane potential of SK-BR-3 cells.

CONCLUSION3-BrPA can inhibit cell proliferation, reduce the mitochondrial membrane potential and induce apoptosis in SK-BR-3 cells, the mechanism of which may involve a reduced ATP level by inhibiting glycolysis and increasing the reactive oxygen level in the cells.

OBJECTIVETo investigate the anti-cancer effect of low-molecular-weight heparin (LMWH) combined with doxorubicin and explore the mechanism.

METHODSHepatocellular cancer HepG2 cells exposed to LMWH, doxorubicin, or both were evaluated for cell viability with MTT assay and for changes in their migration ability using wound healing assay and Transwell migration assay. The changes in cellular expressions of matrix metalloproteinase-9 (MMP-9) and MMP-2 mRNA and proteins were analyzed with quantitative real-time PCR (qRT-PCR) and Western blotting, and ELISA was used to determine heparanase (HPA) concentration in the cell culture medium.

RESULTSHepG2 cells exhibited suppressed proliferation in response to LMWH and doxorubicin treatments. The combined treatment caused a significantly higher inhibition rate of cell migration than LMWH and doxorubicin alone. LMWH enhanced doxorubicin-induced down-regulation of MMP-9, MMP-2 and HPA in the cells.

CONCLUSIONSLMWH can enhance the inhibitory effect of doxorubicin on the migration of HepG2 cells, the mechanism of which may involve the down-regulation of MMP-9, MMP-2 and HPA expressions.

OBJECTIVETo investigate the antineoplastic effects of 2-Deoxy-D-glucose (2-DG) combined with Taxol on orthotopically transplanted breast cancer in C3H mice and explore the mechanism.

METHODSC3H mice bearing orthotopically transplanted breast cancer xenograft were randomly divided into 4 groups, namely the control group, 2-DG group, Taxol group, and 2-DG+Taxol group. The corresponding drugs were administered intraperitoneally every 3 days for 18 consecutive days, and the tumor volume was measured every 3 days to draw the tumor growth curve. The mice were then sacrificed to measure the tumor weight on day 19 and examine tumor cell apoptosis with TUNEL assay and VEGF expression using immunohistochemistry.

RESULTS2-DG combined with Taxol obviously suppressed the tumor growth with a tumor inhibition rate of 66.06% as compared to the rate of 36.97% in Taxol group. The combined treatment also caused more obvious cell apoptosis and significantly reduced VEGF expression in the tumor cells as compared with the other groups.

CONCLUSION2-DG can enhance the inhibitory effect of Taxol on orthotopically transplanted breast cancer xenograft in C3H mice probably by inducing tumor cell apoptosis and lowering VEGF expressions.

Objective     To investigate activated toll-like receptor-4 (TLR4) signaling pathway involved in pathophysiological mechanisms of type A aortic dissection (TAAD). Methods     Specimens of full-thickness ascending aorta wall from the TAAD patients (n=12) and the controlled donors (n=12) were collected. Western blotting was used to examine the associated proteins' expression of TLR4 signaling pathway. Blood samples from TAAD (n=43) and controlled patients (n=50) were examined by enzyme-linked immunosorbent assay (ELISA) to detect the circulating plasma cytokines levels of interleukin-1β (L-1β). Results     In the aortic wall of TAAD, expression levels of TLR4 and protein expression of major molecule significantly elevated, and activated macrophages increased. Furthermore, elevated IL-1β levels were observed in the TAAD patients’ plasma compared with the control plasma. Multiple logistic regression analysis and receiver operating characteristic (ROC) curve showed that elevated IL-1β could be a novel and promising biomarker with important diagnostic and predictive value in the identification of TAAD. Conclusion     Activated TLR4/NF-κB signaling pathway regulates inflammatory response to involve in pathophysiological mechanisms of type A aortic dissection and its regulated inflammatory products have important predictive value for patients with TAAD.
