目的：探讨艾灸对健康人甲皱微循环及血液流变学的影响。方法：选择健康学员及武警战士各30例，年龄20－22岁，应用江苏协达公司生产的XDM－1型微循环电脑检测仪及北京世帝科学仪器公司生产的LG－R－80血液粘度计，LG－B－190型红细胞变形／聚集测试仪。固定专人操作，分别于艾灸前及艾灸后，测试甲皱微循环及血液流变学各项指标的变化。结果：艾灸八邪及三阴交穴后，甲皱微循环各项指标均有明显变化，经统计学处理，红细胞聚集程度、血流速度、流态积分、管周积分均有显著性差异（P＜0．05），其余各项指标虽有不同程度的改变，但无统计学意义（P＞0．05）；血液流变学各项指标亦有明显变化，经统计学处理，全血低切相对粘度、全血低切还原粘度、红细胞刚性指数、红细胞聚集指数及血浆纤维蛋白原都有非常显著性差异（P＜0．01），全血高切相对粘度有显著性差异（P＜0．05），其余各项指标虽有不同程度的改变，但无统计学意义（P＞0．05）。结论：艾灸八邪及三阴交穴后可明显改善红细胞聚集程度，降低血液粘度，加快血流速度，降低外周血管阻力。     

急性软脑膜微循环障碍实验模型的研究

本文报道应用高分子右旋糖酐制成软脑膜微循环障碍的动物实验模型。软脑膜微循环障碍模型的标志;软脑膜微血管血流速度减慢,血液流态呈粒状流或絮状流,血细胞聚集。 将98只家兔分成甲、乙二组。甲组38只,静脉注射平均分子量为25万的高分子右旋糖酐,乙组60只,静脉注射平均分子量为49万的高分子右旋糖酐。实验结果发现,甲组38只家兔仅28只可复制成软脑膜微循环障碍的实验模型,模型复制成功率为73.6％;乙组60只家兔,59只可形成软脑膜微循环障碍实验模型,成功率为98.3％。本实验证明复制动物模型以49万分子量的高分子有旋糖酐为宜。 本实验模型可用于脑微循环障碍和改善脑微循环药物的研究工作。     

Fat-Derived Hormone Adiponectin Combined with FTY720 Significantly Improves Small-for-Size Fatty Liver Graft Survival

Owing to the discrepancy between organ donation and the demand for liver transplantation, expanding the liver donor pool is of vital importance. However, marginal liver grafts, such as small-for-size and/or fatty grafts, were associated with primary graft nonfunction or poor function. Therefore, novel combination therapies to rescue small-for-size fatty liver grafts should be investigated. In this study, we applied a combination therapy using a fat-derived hormone adiponectin (anti-steatosis) plus immunomodulator FTY720 (anti-inflammatory) in a rat liver transplantation model using small-for-size fatty liver grafts, and investigated the underlying protective mechanism such as anti-steatosis, intra-graft energy metabolism, hepatic microcirculatory changes, cell signaling cascades for survival, apoptosis and inflammation. The current study demonstrated that even a single treatment of adiponectin or FTY720 improved the 7-day graft survival from 0% to 62.5% (p = 0.001). The combination therapy significantly increased the 7-day graft survival rate to 100% by remarkable attenuation of graft steatosis and acute phase inflammatory response, significant activation of cell survival Akt pathway and maintenance of intra-graft adenosine triphosphate metabolism and improvement of hepatic microcirculation. In conclusion, the fat-derived hormone adiponectin combined with FTY720 might be a novel combination drug therapy for prevention of small-for-size fatty liver graft injury.

A Study of Hemorrheologic Changes in Patients with Severe Viral Hepatitis

The study of the micro and macro-hemorrheologic changes and theflow conditions of the nail-fold microcirculation in 30 patients with severe viralhepatitis was reported.Normal individuals,and patients with acute icterichepatitis or chronic active hepatitis were employed as the controls.The changes observed in the patients with severe viral hepatitis were asfollows:The reduced viscosity of the whole blood and the plasma viscosityincreased markedly;the dispersion rate of the values of blood viscosity increasedas the clinical state of the patient became worse;and the factors increasing theblood viscosity(i.e.increase of the immuno-globulin level,prolongation of theerythrocyte electrophoretic mobility time,and increase of RBC sedimentation rate)and those decreasing the blood viscosity(i.e.decrease of hematocrit reading,fibrinogen level and platelet aggregation ratio)existed simultaneously in thepatient.The changes of the flow conditions of the nail-fold microcirculation werein close correlation with the increase of blood viscosity and the severity of thedisease.The etiology and mechanism of the above mentioned changes were discussed
