Serum Hypersensitive C-reactive Protein (hs-CRP) in Pediatric Infection in Clinical Application / 昆明医科大学学报

Objective Explore the diagnostic effect of high-sensitivity C-reactive protein (hs-CRP) in pediatric infectious diseases. Methods The BNProSpec automatic protein analyzer was used to detect the serum hs-CRP levels of children including 246 cases of bacterial infection, 132 cases of virus infection and 72 cases of healthy children (control group) . Results The serum hs-CRP levels were 57.2±19.5 mg/L,4.6±3.2 mg/L and 1.7 ±0.4mg/L in children of the bacterial infection, virus infection and normal control group, respectively. Conclusion The serum levels of hs-CRP in children with bacterial infection were significantly higher than those in other two groups,and the difference was significant ( <0.05) . The results suggested that serum hs-CRP testing has great application value in the diagnosis of pediatric infectious diseases, treatment and prognosis.

Expression of Engrailed-2 and β-catenin in bladder urothelial carcinoma and their significance / 南方医科大学学报

<p><b>OBJECTIVE</b>To investigate the expressions of Engrailed-2 (EN2) and β-catenin in bladder urothelial carcinoma and explore their significance.</p><p><b>METHODS</b>Sixty bladder urothelial carcinoma samples of different grades and stages and 10 normal bladder mucosal tissues were examined for expressions of EN2 and β-catenin proteins and mRNA using immunochemistry, Western blotting and RT-PCR. RESULTS Compared to normal bladder mucosa, bladder urothelial carcinoma tissues showed significantly increased expressions of EN2 and β-catenin proteins (P<0.05), and the high-grade carcinoma tissues exhibited significantly stronger expressions than the low-grade ones (P<0.05); the expressions of the proteins increased also significantly with advanced pathological stages of bladder urothelial carcinoma (P<0.05). The expressions of EN2 and β-catenin mRNAs showed a consistent pattern of changes with their protein expressions.</p><p><b>CONCLUSION</b>The expressions of EN2 and β-catenin are significantly increased in bladder urothelial carcinoma. EN2 may contribute to the development and progression of bladder urothelial carcinoma by activating Wnt/β-catenin signal pathway.</p>
