Objective To search novel genes or pathways involved in the recovery process after restraint stress in rats. Methods We compared the hypothalamus transcriptional profiles of two different recovery patterns (fast recovery vs slow recovery) from restraint stress in rats using oligonucleotide microarray, the recovery pattern was determined by the decrement of plasma adrenocorticotropic-hormone (ACTH) and corticosterone levels during one hour recovery period after stress. A real-time quantitative RT-PCR was applied to validate the differential expressed genes. Results Analysis of the microarray data showed that most of genes were not differentially expressed between fast recovery group and slow recovery group. Among the differentially expressed genes we found that talin, together with serine/threonine protein phosphatase PPl-beta catalytic subunit (PP-1B) and integrin α-6 precursor (VLA-6) genes, were at least 1.5 fold upregulated in the fast recovery group, while junctional adhesion molecule 1 (F11r) was 1.5 fold down-regulated in the fast recovery group. Conclusion The results implied that integrin signaling pathway may be involved in the recovery from restraint stress in rats. The present study provided a global overview of hypothalamus transcriptional profiles during the process of recovery from the restraint stress in rats. The integrin signaling pathway seems to be involved in the recovery process, which deserves further study to clarify the integrin-mediated recovery mechanism after restraint stress.

b型流感嗜血杆菌(Haemophilus influenza type b,Hib)是全球范围内引起3个月到5岁龄儿童肺炎、脑膜炎和败血症等严重疾病的重要病原菌。接种疫苗是唯一有效的预防和控制Hib引起疾病的公共卫生措施,将Hib结合疫苗纳入儿童常规免疫程序的国家,Hib发病率和携带率均明显降低。本文现对Hib疫苗种类、免疫学特性、临床效力以及Hib新型疫苗或联合疫苗的免疫原性评价方法作一综述。
