ABSTRACT
<p><b>OBJECTIVE</b>To study the expressions of tumor necrosis factor alpha-induced protein 3(TNFAIP3) and mammary serine protease inhibitor (Maspin) in the radiotherapy of nasopharyngeal carcinoma and explore the differences in radiosensitivity and radioresistance,the relation with the occurrence and development of radioresistance.</p><p><b>METHODS</b>The TNFAIP3 and Maspin mRNA expressions were detected by using TNFAIP3 and Maspin multi-point labeled DIG probes in situ hybridization.</p><p><b>RESULTS</b>In radiosensitivity and radioresistance of nasopharyngeal carcinoma,the moderately and strongly positive TNFAIP3 mRNA expression rates were 27.50% and 48.33% (P=0.037), and the moderately and strongly positive Maspin mRNA expression rates were 67.50% and 46.67% (P=0.040). In the radioresistance of nasopharyngeal carcinoma,TNFAIP3 mRNA moderately and strongly positive expressions were positively correlated with TNM stage (P=0.005). In distant metastasis and no distant metastasis (70.00% and 37.50%, P=0.018), the expression rates had statistical significance. The Maspin mRNA moderately and strongly positive expressions were positively correlated with TNM stage (P=0.039) and T stage (P=0.021). In distant metastasis and no distant metastasis (65.00% and 37.50%, P=0.044), the expression rates had statistical significance.</p><p><b>CONCLUSION</b>TNFAIP3 may be involved in the development of radioresistant nasopharyngeal carcinoma,and Maspin may be related with the invasion and metastasis of radioresistant nasopharyngeal carcinoma.</p>

Objective To study the epidemiological characteristics of abnormal glucose and lipid metabolism in in-patients with ischemic stroke. Methods A total number of 771 in-patients with ischemic stroke, hospitalized in the Department of Neurology/Endocrinology from Changzhou No.2 Hospital from April 2007 to April 2008 were enrolled in this study. After identifying the condition of glucose metabolism, all diagnosis-undetermined patients received oral glucose tolerance test. Results Among in-patients with ischemic stroke, 41.8% of the patients were finally diagnosed as diabetes, with 23.4% classified as 'impaired glucose tolerance'. The prevalence of 'abnormal glucose metabolism' was 65.2% in total. If diabetes in the in-patients with ischemic stroke was diagnosed only by fast plasma glucose instead of oral glucose tolerance test, 58.5% diabetic patients would have been misdiagnosed. Abnormal lipid metabolism existed in inpatients with cerebral ischemic stroke were noticed. These abnormalities of lipid metabolism were mainly consisting of increased triglyceride and decreased HDL-C cholesterol. Conclusion The majority of in-patients with ischemic stroke appeared to have had abnormal glucose and lipid metabolism. It seemed necessary to promptly and correctly diagnose these patients with abnormal glucose metabolism by oral glucose tolerance test to reduce the chances of developing the recurrence of stroke.
