Résumé

<p><b>OBJECTIVE</b>To investigate the epidemiological characteristics of measles cases of new genotype D8 in Beijing from January to June, 2013.</p><p><b>METHODS</b>Epidemiological survey and descriptive analysis was conducted.</p><p><b>RESULTS</b>661 suspected measles were reported from January to June, 2013. 416 were confirmed measles cases by serology and etiology detection. 28 measles cases were caused by genotype D8 measles virus by genotype identification. There were 2 measles outbreak including 14 cases and 14 sporadic cases. The incidence peak was during April and May. 25 cases (89.3%, 25/28) occurred in downtown and suburban districts. 22 cases (78.5%, 22/28) were adults aged 15-39 years and 19 cases (67.9%, 19/28) were migrant population. 12 cases (85.7%, 12/14) in outbreak were migrant population working in clothing sales. There was epidemiological association between 2 outbreaks.</p><p><b>CONCLUSION</b>Measles cases of genotype D8 were found for the first time in Beijing. Genotype D8 virus mainly infected migrant adults and caused local outbreak and endemic.</p>

Résumé

<p><b>OBJECTIVE</b>To study the possible role of JNK1, Raf-1 and Livin in the carcinogenesis of sporadic colorectal tubular adenoma.</p><p><b>METHODS</b>Immunohistochemical staining was used to detect the expression of JNK1, Raf-1 and Livin proteins in 65 sporadic colorectal tubular adenomas with dysplasia of varying degrees and 22 colorectal tubular adenoma with cancerous area.</p><p><b>RESULTS</b>In normal colorectal mucosa, colorectal tubular adenoma with dysplasia and colorectal tubular adenoma with cancerous area, the positive rate of JNK1, Raf-1 and Livin expression was increased gradually. The positive expression of JNK1, Raf-1 and Livin was all significantly higher in the cases of colorectal tubular adenoma with dysplasia or with cancerous area than that in normal colorectal mucosa (P < 0.05), and the positive expression of JNK1, Raf-1 and Livin was significantly higher in colorectal tubular adenoma with cancerous area than that in colorectal tubular adenoma with dysplasia of different degrees (P < 0.05). In the cases of colorectal tubular adenoma with dysplasia of varying degrees, the positive expression of Raf-1 was increased along with the increasing dysplasia degree of colorectal tubular adenoma (P < 0.05). Coexpression of JNK1, Raf-1 and Livin increased gradually in the carcinogenesis of sporadic colorectal tubular adenoma, while positive correlation was found among the expressions of JNK1, Raf-1 and Livin.</p><p><b>CONCLUSION</b>JNK1, Raf-1 and Livin may be involved in the carcinogenesis of sporadic colorectal tubular adenoma.</p>
