Objective To compare the efficacy of tamsulosin and nifedipine for the adjunctive expulsive therapy in patients with lower ureteral stones. Methods A total of 180 patients with stones (0.4-1.0 cm in diameter) located in the lower ureter (juxtavesical or intramural tract) were randomly divided into 3 groups (60 cases in each group). Group 1 served as controls; group 2 received nifedipine (10mg, 3 times daily) ; and group 3 received tamsulosin (0.4 mg, once daily). All patients were observed for 2 weeks. Results During 2 weeks, expulsion of stones was observed in 26 cases (43. 3% ) of group 1, in 44 (73. 3% ) of group 2, and 49 (81. 1% ) of group 3. The difference in expulsion rates between groups 2, 3 and group 1 was statistically significant (P 0. 05). In groups 1 , 2 and 3, renal colic recurred within 2 weeks and analgesics were used in 5 cases (8.3%), 1 (1.7% ) and 0, respectively, with significant difference between the groups (P

Objective To estimate the expressions of cyclin D1 and Ki67 in esophageal squamous cell carcinomas and their clinical significance. Methods The expressions of cyclin D1 and Ki67 were detected by immunohistochemistry in 28 specimens esophageal squamous cell carcinoma (ESCC) and 33 samples esophagitis tissue. Results The positive expression rate of cyclin D1 in ESCC and esophagitis tissues was 60.7% (17/28) and 33.3% (11/33) respectively (?2=4.573,P=0.032),while the mean Ki67 label index (Ki67 LI) was (49.21?25.15)% and (11.62?9.87)% respectively (t=7.908,P=0.000). The positive expression rate of cyclin D1 in TNM stage I tissues was 14.3% (1/7),which was significantly lower than that in stages Ⅲ and Ⅳ tissues[85.7% (6/7) and 100% (5/5),P=0.029 and 0.015,respectively]. In cases with lymph node metastasis,the positive rate of cyclin D1 expression was 90.9% (10/11) that was significantly higher than that in those without lymph node metastasis (P=0.016). The 28 patients with ESCC were followed up for 6 to 34 months [mean,(25.0?4.2) months],during which 19 patients survived,4 patients died of deterioration of the primary diseases (3 cases) or cerebrovascular affair (1 case),and the other 5 patients was lost to follow-up. Conclusions The expression of cyclin D1 is correlated with advanced tumor and lymph node metastasis. The Ki67 is highly expressed in ESCC tissues; no relationship exists between the level of the expression and the pathological differentiation type and TNM stage of ESCC.

Objective To evaluate the risk factors for prognosis in liver cirrhotic patients with acute esophageal variceal bleeding (EVB). Methods Retrospective analysis was carried out in patients with liver cirrhosis,who were admitted to the hospital for EVB between January 2000 and December 2006 . All patients were follow-up to August 31st, 2009. The death of the patients was identified as the end of the study. The vital signs and results of laboratory tests were recorded when patients were admitted to the hospital. Child-Pugh score/grade, model for end stage liver disease (MELD) score and Rockall score were calculated. Results Ninty-five cases (66 males and 29 females) were enrolled in the study. Among them, 60 cases died and 35 cases survived for (42. 61±33.21) months (ranged from 2 days to 114 months). Univariate Cox regression analysis showed that age, male, Child-Pugh score/grade, MELD score, Rockall score, white blood cell counts and active hepatitis B were risk factors for death in liver cirrhotic patients with EVB (P<0.05), while high level of hemoglobin and high hematocrit, endoscopic variceal sclerosis therapy or surgical treatment were protective factors (P<0.05). Multivariate Cox regression analysis revealed that Child-Pugh grade (RR= 4. 997,95%CI:2. 787~8. 960, P<0.01),Rockall score (RR= 1. 284,95%CI:1. 062~1. 553,P=0. 010), high counts of white blood cells (RR= 1. 072,95%CI: 1. 001 ~ 1. 148, P= 0. 046) were risk factors for prognosis of liver cirrhotic patients with EVB. Conclusion It is demonstrated that Child-Pugh grade,Rockall score and high counts of white blood cells are risk factors for prognosis of liver cirrhotic patients with EVB.

Objective To analyze the characteristics of somatotypes of South Asian type, North Asian type and East Asian type, and to compare the main differences among them. Methods The characteristics of somatotypes among South Asian type, North Asian type and East Asian type in 29 Chinese Mongolian ethnic groups were compared by using the Heath-Carter anthropometric somatotype. The reasons for differences of South Asian type were that North Asian type were analyzed by using principal component analysis. Results The male groups of North Asian type were endomorphic mesomorph and the South Asian types were balanced mesomorph, while the East Asian types differed greatly from each other.The female groups of North Asian types and the East Asian types were mesomorphic endomorph and the South Asian types were endomorphic mesomorph. The somatotypes of East Asian types were similar to North Asian types but were greatly different from South Asian types.Principal components analysis showed that the main differences between South and North of male groups lied first in ectomorphy and then in endomorphy.The differences between female groups of South and North were mainly on endomorphy. Conclusion The ethnic group of North Asian type is higher than South Asian type in endomorphy but lower in ectomorphy.
