Effects of Xingshen Jieyu Decoction on levels of Th1/Th2 and BDNF in rats with post-stroke depression
Objective,2,To study the effect of Xingshen Jieyu Decoction on serum Th1/Th2 and brain-derived neurotrophic factor(BDNF) levels in post-stroke depressive (PSD) rats, and to analyze the possible mechanism of Xingshen Jieyu Decoction in treating the disease.,Methods,2,SD rats were randomly divided into normal group, stroke group, post-stroke depression group, sertraline group, low-dose group of Xingshen Jieyu Decoction, and high-dose group of Xingshen Jieyu Decoction. The stroke model was established by the right middle cerebral artery ischemia-reperfusion operation. The chronic unpredictable mild stress (CUMS) method was added at 3 days after the middle cerebral artery occlusion (MCAO) operation for PSD model. In the medicine groups the sertraline (5.142 g/kg) and high or low dose (56.148 g/kg, 18.176 g/kg) of Xingshen Jieyu Decoction were used after the establishment of PSD model respectively. The enzyme-linked immunosorbent assay (ELISA) was used to detect the contents of serum inflammation factors including Th1 (IL-6, IFN-γ), Th2 (IL-4, IL-10) and BDNF.,Results,2,Compared with those in the normal group, the serum Th1/Th2 ratio in the post-stroke depression group increased significantly, the levels of anti-inflammatory factors such as IL-4, IL-10, and BDNF decreased significantly, and the levels of pro-inflammatory factors such as IL-6 and IFN-γ increased significantly (,P,<,0.05); compared with those in the post-stroke depression group, the serum Th1/Th2 ratio was decreased significantly and the contents of IL-4, IL -10 and BDNF were increased significantly, but the contents of IL-6 and IFN-γ were decreased significantly (,P,<,0.05) in the post-stroke depression groups with low-dose, high-dose of Xingshen Jieyu Decoction.,Conclusion,2,Xingshen Jieyu Decoction can improve the neurological function and depressive behavior of post-stroke depression rats by regulating the levels of Th1 / Th2 and BDNF.
