ABSTRACT
Objective To observe the effect of stone removal and relieving renal colic with Xiere-Zhuyu-Paishi decoction and auxiliary lithotripsy in patients with upper ureteral calculi. Methods A total of 80 patients with upper ureteral calculi were divided into the observation group and the control group according to the random number table method, with 40 in each group. Both groups were treated with extracorporeal shock wave lithotripsy (ESWL) as the basic treatment. Besides, the control group added the western medicine, such as pain relieving, spasmodic and anti-infection while, the observation group with Xiere-Zhuyu-Paishi decoction. Both groups were treated for 4 weeks. After 1 courses of treatment, the curative effect was evaluated. The effect of lithotripsy (lithotripsy success rate, stone clearance rate, stone expulsion time), renal colic improvement (renal colic rate, analgesic drug usage rate, pain visual analogue VAS score) and WHOQOL-BREF scores were compared. Results After treatment, the total efficiency of observation group was 92.5％ (37/40), while the control group was 75％ (25/40), and the difference was statistically significant (Z=-3.082, P=0.004). After treatment, the observation group stone clearance rate was 92％ (36/40), while the control group was 72.5％ (29/40), and the difference was statistically significant (χ2=3.986, P=0.031). After treatment, the incidence of renal colic of the observation group was 12.5％ (5/40), while the control group was 32.5％ (13/40), and the difference was statistically significant (χ2=3.146, P=0.037). The analgesic drug usage rate in the observation group was 5％ (2/40), while the the control group was 25％ (10/40), and the difference was statistically significant (χ2=4.021, P=0.019). After treatment, the observation group lithecbole time, pain VAS score levels in the observation group was significantly lower than those in the control group (t=6.261,5.743, all Ps<0.01). After treatment, the WHOQL-BREF score, the physiological domain score, psychological field score, social relationship domain score, environment the field score in the observation group were significantly higher than those of control group (t values were 6.731, 4.342, 5.064, 4.521, 5.128, all Ps<0.01).Conclusions The application of Xiere-Zhuyu-Paishi decoction and auxiliary lithotripsy in patients with upper ureteral calculi can promote stone removal in upper ureteral stones, alleviate renal colic and improve the quality of life of the patients.

ABSTRACT
Objective To compare the efficacy and safety of prourokinase,reteplase and urokinase on the patients with acute ST -segment elvation myocardial infarction.Methods According to random number table,the eligible patients with acute ST -segment elvation myocardial infarction were randomly divided into prourokinase group (50mg,n =34),reteplase group (36mg,n =42)and urokinase group (1 500 000IU,n =32).The patency of infarct related coronary artery was estimated by coronary angiography at 90min after administration of thrombolytic agents.The adverse reaction was also observed including bleeding and the major adverse cardiac events(MACEs).Results The patency of culprit vessel in the prourokinase group was 76.50% (≥TIMI 2 flow),which in the reteplase group was 83.30% (≥TIMI 2 flow),and which in the urokinase group was 53.10% (≥TIMI 2 flow),respctively.Both of prourokinase group and reteplase group were higher in the patency than theurokinase group(χ2 =8.27,P =0.004). The MACEs and bleeding adverse reaction(prourokinase group 17.65%,reteplase group 28.57%,urokinase group 42.19%)showed that security of prourokinase group was securer than reteplase group and urokinase group(χ2 =6.36,P =0.012).Conclusion Both of prourokinase and reteplase are effective for the patients with acute myocardial infarction with ST -segment elvation,and prourokinase is safer.
