Objective To investigate the expression of HIF-1α and survivin in renal clear cell carcinoma (RCC) and normal renal tissue ( NRT) and explore the correlation between HIF-1α and survivin expression. Method SABC immunohistochemical staining was performed to detect the expression in 32 cases of RCC and 10 cases of NRT.Results The level of positive HIF-1α immunostaining in RCC(0. 037 ±0. 0182,0. 093 ±0. 0384,respectively) was higher than NRT(0. 008 ±0.0055,0. 014 ±0. 0059, respectively) ( P<0. 05). The level of positive survivin immunostaining in RCC(0. 053 ±0.0179,0. 137 ±0.0291) was higher than NRT( P<0. 05). The expression of HIF-1α and survivin had positive relationship with clinical stage in RCC(0. 029 ±0. 0117,0.070±0.0154)( P <0.05). The expression of HIF-la had relation with survivin in RCC( r = 0. 655, P < 0. 05).Conclusion The expression of HIF-1α was strongly positive correlated with survivin ( r = 1.000,0. 655, P <0. 05).

OBJECTIVE: To treat superficial hemangioma in children according to the local blood flow. METHODS: A total of 98 children with superficial hemangiomas admitted to our hospital from January 2005 to June 2009, and their clinical data were analyzed. RESULTS: According to the local blood flow velocity, 98 children were treated with injections or injection plus surgical treatment, respectively. Ninety-four children (95.9%) were cured. CONCLUSION Injection therapy is effective for children with superficial hemangioma, but we should arrange individualized treatment according to the local blood flow in children.
