大鼠异体肢体移植术后急性排斥反应阶段血管内皮细胞ICAM-1表达的动态变化

Objective To investigate the dynamic changes of intercellular adhesion molecule-1 (ICAM-1) expression in endothelial cells (EC) during hindlimb allograft acute rejection in rats and the inhibitory effect of cyclospofine A (CsA) on the acute rejection. Methods The rat model of hindlimb allograft was developed. The rats were randomly divided into following groups: control group (Wistar→Wistar), rejection group ( Sprague-Dawley→Wistar) and CsA-treated group (Sprague-Dawley→Wistar). At postoperative day 1, day 4 and day 7samples of the femoral artery from the allograft limb were harvested to observe the pathologic changes. ICAM-1 expression in EC was quantified using immunohistochemical assay. Results Slight swelling and weak ICAM-1expression of EC were observed in the control group. In the rejection groups, obvious EC swelling and massive lymphocyte infiltration were seen. ICAM-1 expression in EC was significantly stronger and elevated. In CsA-group only mild infiltration of lymphocytes was seen and ICAM-I expression in EC was also much weaker.Conclusion During rat hindlimb allograft acute rejection the expression of ICAM-1 in EC was closely related to the occurrence and development of acute rejection. CsA could reduce the expression of ICAM-1 in EC and hence inhibit acute rejection of composite allograft.

Thyroid diseases associated with interferon α treatment for viral hepatitis

There are many complications during the interferon alpha (IFNα) treatment for viral hep-atitis,and thyroid disease is the most common side-effect in endocrine aspects. Thus, clinicians are drawing much attention to the interferon induced thyroiditis (IIT). Though the etiology is not clear,some factors may contribute to the susceptibility to IIT, such as genetic predisposition, gender,and hepatitis C virus (HCV) in-fection. The pathogenesis may be secondary to immune modulation by IFNα and/or by its direct effects on the thyroid. Autoimmune IIT may manifest as Graves' disease, Hashimoto's thyroiditis and the development of thyroid antibodies without clinical symptoms. Non-autoimmune IIT can manifest as destructive thyroiditis or hypothyroidism with negative thyroid antibodies. Screening for autoantibodies and serum thyroid-stimulating hormone(TSH)is recommended before, during and after IFNα treatment. Early detection and therapy of these conditions is important.     

六经气津互化论

气与津皆生于水谷,气生于水,水化于气,津即为水。由于气津互化的密切关系,故任何一方的改变,都会影响到另一方,即所谓水化于气,亦能病气;气生于水,亦能病水。因此,太阳经气可概括为两大功能,即卫外和气化,是由气津互化而体现的;阳明气津之间,表现为相互制约;少阳经的气津互化,关系到少阳气机的条达舒畅及三焦水道的通调运使;太阴脾气的健旺,可使津液化生有源;少阴心肾精血充沛,滋养有时,才可使心肾之气化生有源;而厥阴之气的条达顺畅,又可维持津液代谢的平衡状态。

庆大霉素对豚鼠前庭上皮IGF-1及其受体表达的影响

目的：研究庆大霉素对豚鼠前庭上皮胰岛素样生长因子-1（insulin-like growth factor-1，IGF-1）及其受体（insulin-like growth factor-1 receptor，EGF-1R）表达的影响，并探讨其生物学特性。方法：采用免疫组织细胞化学方法，以抗IGF-1及IGF-1R抗体为标记物，检测庆大霉素损伤后豚鼠前庭上皮自发修复期IGF-1及IGF-1R的表达变化和分布特点；采用Brdu体内标记和抗Brdu抗体免疫组化染色，检测庆大霉素损伤后豚鼠前庭上皮增殖的变化。结果：IGF-1及IGF-1R在正常成年豚鼠前庭上皮细胞中有低水平表达，庆大霉素损伤后，其表达增多。在1d组IGF-1及IGF-1R表达最强，其后逐渐减少。在正常对照组中无Brdu阳性细胞。各实验组均观察到Brdu阳性细胞，7d组最多。结论：庆大霉素损伤后，豚鼠前庭上皮IGF-1及IGF-1R表达增强，其时程变化与细胞增殖活动密切相关。IGF-1在豚鼠前庭上皮损伤后的细胞增殖中可能起重要信号转导作用。
