Objective To investigate the clinical effect of non-steroidal anti-inflammatory drugs and αl-adrenergic antagonist on treating patients with ureteral stones.Methods A total of 128 patients with ureteral colic due to ureteral stones were randomly divided into control and treatment group,and 64 cases in each group.Both two groups were treated with tamsulosin 0.4 mg oral,intravenous injection of saline 1000 mL Patients in treatment group were received intramuscular non-steroidal anti-inflammatory drugs(10 mg) and patients in control group were received pethidine hydrochloride(10 mg).Ultrasound exam were performed after 6-8 h to evaluate the stone expulsive rate.Extracorporeal shock wave lithotripsy and other treatment were underwent when the stone was still not discharge.Results The effective rate of analgesia was 96.9％ (62/64) in treatment group and 100％ (64/64) in control group(x2 =2.03,P =0.50).The stone expulsion rate in treatment group was 28.1％ (18/64),higher than that in control group(12.5％ (8/64),x2 =4.83,P =0.05).Conclusion It is effective to relive ureteral cohc with non-steroidal anti-inflammatory drugs only,and it is better than pethidine in promote stone expulsion when they both used with α1-adrenergic antagonist.

Objective To observe the expression and significance of hypoxia inducible factor (HIF)-1α,matrix metalloproteinase(MMP)-9 and transforming growth factor(TGF)-β1 in liver tissues of rats with hepatic fibrosis and the effects of TGF-β1 vaccine on the expressions of HIF-1α,MMP-9 and TGF-β1.Methods The hepatic fibrosis rat model was set up by dimethylnitrosamine (DMN).The rat model was injected with TGF-β1 vaccine.The expressions of HIF-1α,MMP-9 and TGF-β1 were detected by immunohistochemistry in rat fibrosis tissues after 6 weeks.Results The expressions of HIF-1α,MMP-9 and TGF-β1 in fibrosis model group and TGF-β1 vaccine group were all significantly higher than control group(P＜0.01),which was positively correlated with the fibrosis degree(r=0.911,0.814 and 0.836,respectively,P＜0.01).However,the expressions of HIF-1α,MMP-9 and TGF-β1 in TGF-β1 vaccine group were all significantly decreased than fibrosis model group (t=2.62,4.03,3.43;P＜0.01).Conclusion During the development of liver fibrosis,HIF-1α promotes the transcriptions and expressions of MMP-9 and TGF-β1.
