In this paper, we are concerned with positive entire solutions to elliptic equations of the form Δu+ f(x,u)= 0 x∈ RN N ≥ 3 where u →f(x,u) is not assumed to be regular near u = 0 and f(x,u) may be more general in...In this paper, we are concerned with positive entire solutions to elliptic equations of the form Δu+ f(x,u)= 0 x∈ RN N ≥ 3 where u →f(x,u) is not assumed to be regular near u = 0 and f(x,u) may be more general involving both singular and sublinear terms. Some sufficient conditions are given with the aid of the barrier method and ODE approach, which guarantee the existence of positive entire solutions that tend to any sufficiently large constants arbitrarily prescribed in advance.展开更多

Methods cyclin E and p27kipl expressions were detected in 69 specimens by SP of immunohistochemistry. The results were analyzed in relation to the clinical data. Results The positive rates of cyclin Eexpression and p27kipl expression in bladder carcinoma were 42 % and 51 %, respectiely. cyclin Eexpression was positively related to the tumor grade, the higher the tumor grade, the higher the cyclin E positive expression; but there was no association between cyclin Epositive expression and tumor clinical stage. Significant correlation was found between p27kipl positive expression and tumor grade and clinical stage, the lower the p27kipl positive expression, the highter the tumor grade and clinical stage. In relapsing bladder carcinoma,both cyclin E and p27kipl positive expression decreased significantly. There was close correlation between cyclin E expression and p27kipl展开更多
