Objective To study the preventive and therapeutic effect of doxazosin mesylate (Cardura) in the management of vesical spasm. Methods Two hundred and fifty six cases were randomized into two groups: the study group was given Cardura 4 mg at bedtime, while the control group was given probanthine 15 mg twice a day. All the patients were given 8 ng of Vitamin Ks three times a day. Results There was significant difference in the incidence of vesical spasm between study group and control group (P＜0.01). Conclusions Cardura can decrease the urethral closure pressure, and reduce excitability of bladder detrusor muscle. So it is effective for the relief of vesical spasm.

Objective To investigate the effects of non-ionic low osmolar contrast media (LOCM) on the apoptosis and mRNA expression of Bcl-2/Bax in rat glomerular endothelial cells cultured in vitro. Methods Rat glomerular endothelial cells were exposed to ioversol with different concentrations for different time. Cell viability was then assessed by MTT method and morphological changes of cells were observed by inverted microscopy. In order to analyze cell apoptosis, DNA electrophoresis was applied. Meanwhile, the expression changes of Bcl-2/Bax at mRNA level were determined by RT-PCR. Results The viability of rat glomerular endothelial cells was inhibited by ioversol in a concentration and time dependent manner. After being exposed to ioversol(90 mL/L)for 24 h, the cells began to become crimple, round, and even floating. A typical DNA ladder determined by agarose gel electrophoresis was observed. Noticeably, the mRNA level of Bcl-2 in ioversol treated cells was down-regulated, while Bax was up-regulated, so that the ratio of Bcl-2 mRNA to Bax mRNA increased significantly. Conclusion Non-ionic LOCM can induce glomerular endothelial cells apoptosis, which may be partly due to the disturbance of Bcl-2/Bax balance. This is probably related to the pathogenesis of contrast media nephropathy.

AIM: To evaluate the influence of radiofrequency (RF) hyperthermia on immunity function in mice. METHODS: The expression pattern of T helper type 1 (Th1) and T helper type 2 (Th2) cytokines in splenocyte culture supernatants, mainly the expression levels of IFN-?, IL-2, IL-4 and IL-10 in splenocyte culture supernatants of mice in tumor-bearing group, surgical resection group, RF therapy group and normal control group were detected by enzyme-linked immunoadsordent assay (ELISA). RESULTS: IL-2 concentration in two weeks after RF therapy group was higher than that in two weeks after surgical resection and normal control groups (P0.05). CONCLUSION: RF hyperthermia may activate the transformation from Th2 to Th1 and facilitate the excretion of Th1 type cytokines that play an important role in the anti-tumor immunity.

Objective To analyze the correlation between the expression of HIF-1α in multiple myeloma (MM) and clinical indexes in order to illustrate the expression and implication of HIF-1α gene in MM. Methods RQ-PCR method was used to amplify HIF-1α mRNA of bone marrow mononuclear cells isolated from 28 cases of MM patients and the control group. β-actin was used as internal standard. HIF-1α mRNA expression was analyzed by SDS software and the ratios of HIF-1α/ β-actin were calculated. Results The relative expression level of HIF-1α mRNA in MM bone marrow mononuclear cells was 12.68 times as that in control group. HIF-1α mRNA was positively correlated with β2-MG (r =0.575, P =0.000), ESR (r =0.522,P =0.000), LDH (r=0.286, P=0.044) and CRP (r =0.356, P =0.011). There was a negative correlation between HIF-1α mRNA and Hb (r =-0.556, P =0.000). Conclusion The expression of HIF-1α mRNA was up-regulated and HIF-1α was related to a number of clinical indexes. HIF-1α may be used to estimate the progress of MM and hopeful to be a new molecular target in cancer therapy.

Aim To investigate the anti-inflammatory activity of ruscogenin,a major sapogenin from Ophiopogon japonicus,effect of ruscogenin on cell adhesion is studied.Methods By MTT assay,effect of ruscogenin on normal and TNF-?-induced adhesion of human pro-myelocytic leukemia cell strain(HL-60)to venous endothelial cell strain(ECV304)was observed and effect of ruscogenin on the viability of ECV304 cells and HL-60 cells were investigated.Results Adhesion between HL-60 cells and ECV304 cells induced by TNF-? was significantly inhibited when ECV304 cells were pretreated with ruscogenin at the concentration of 0.1,1.0 ?mol?L~(-1).Meanwhile,ruscogenin remarkably inhibited TNF-a-induced adhesion when HL-60 cells were pretreated with ruscogenin at the concentration of 0.001,0.01,0.1 ?mol?L~(-1).On the other hand,their viability and adhesion of HL-60 cells to normal ECV304 cells were not affected at above concentrations.Conclusion Ruscogenin shows significant anti-inflammatory activity via inhibition of adherence of HL-60 cells to activated ECV304 cells.

Objective To discuss the effect of Xinxibao to rotavirus enteritis sufferers' humoral immunologic functions.
