摘要: [摘要]〓
〖HTH〗目的〖HTSS〗〖KG*2〗探讨慢性应激致抑郁小鼠血清促血小板生成素(thrombopoietin,TPO)和血管生成素(angiogenin,ANG)的含量变化。
〖HTH〗方法〖HTSS〗〖KG*2〗采用慢性轻度应激(chronic mild stress,CMS)方法建立抑郁小鼠模型,经行为学检测后收集血清,采用酶联免疫吸附测定(enzymelinked immunosorbent assay,ELISA)法对血清白细胞介素6(interleukin6,IL6)、肿瘤坏死因子α(tumor necrosis factorα,TNFα)、TPO和ANG进行定量分析。
〖HTH〗结果〖HTSS〗〖KG*2〗2组总摄水量差异无统计学意义(P>005);应激组糖水偏爱值和强迫游泳测试的不动潜伏期明显缩短,强迫游泳测试的不动时间明显延长,差异均有统计学意义(P<005)。应激组小鼠外周血TNFα、IL6、ANG、TPO水平明显高于对照组,差异均统计学意义(P<005)。
〖HTH〗结论〖HTSS〗〖KG*2〗慢性应激可引起血清TPO和ANG的显著变化,提示抑郁症发生可能与血管发生和血小板功能改变有关。

Abstract: [Abstract] Objective〖HTSS〗〓To investigate the alteration of serum levels of thrombopoietin(TPO) and angiogenin(ANG) in chronic mild stress(CMS)induced depressed mice.
〖HTH〗〖WTHZ〗Methods〖HTSS〗〓CMS procedure was provided in the present study. After depressivelike behavioral tests, serum samples of mice were collected and serum levels of interleukin6(IL6), tumor necrosis factorα(TNFα), TPO and ANG of mice were detected by enzymelinked immunosorbent assay (ELISA). 
〖HTH〗〖WTHZ〗Results〖HTSS〗〓CMS exposed mice exerted significantly depressivelike behaviors, reflected by prolonged floating time(P<005) without significant effect on latency to floating(P>005) in the forced swimming test, decreased sucrose preference(P<005) without significant effect on total intake of sucrose(P>005) in the sucrose preference test. Results from ELISA showed that CMS induced increased serum concentration of IL6, TNFα, TPO and ANG(all P<005).
〖HTH〗〖WTHZ〗Conclusion〖HTSS〗〓CMS exposure could induce significant alteration of serum levels of TPO and ANG, suggesting that the vascular dysfunction and thrombocytopoiesis may be associated with the pathology of CMSinduced depression.
