ABSTRACT
Objective:To explore the relationship between genetic polymorphism of ALDH2 and CYP2E1 and alcoholic liver disease(ALD) in Han people. Methods:PCR-RFLP was used to detect the frequencies of gene types and allele of ALDH and CYP2E1 in health control group(45 cases),ALD group(48 cases),alcohol dependent group(38 cases) and non-ALD(NALD) group(42 cases),and the frequencies were compared. Results:The difference of the frequencies of ALDH2*1 and ALDH2*2 had statistic significance between health control group and ALD group,and between in ALD group and NALD group(P
ABSTRACT
Objective To improve the diagnosis and treatment of upper urinary tract hematuria. Methods A total of 121 patients with hematuria who had undergone B-utrasonography,KUB plus IVU,CT and cystoscopy were suspected of hematuria from upper urinary tract.For these cases ureterorenoscopy was performed to establish the diagnosis and to conduct specific therapies. Results The diagnostic accordance rate was 92%(111/121).Among these cases,ureteral small stones in middle and lower segments were found in 45 cases;renal pelvis and ureteral tumors in 32 cases;renal hemorrhagic diseases in 19 cases and ureteral polyps in 15 cases.19 cases who had renal hemorrhagic diseases and 10 who had no definite lesions received specific therapies were followed up for 6 to 8 months.The long-term successful rate was 79%(23/29). Conclusions The application of ureterorenoscopy for the management of upper urinary tract hematuria is quite effective and worthy of widespread application.
