Aim To study the regulatory of Jiaweisini-san on expression of hippocampal BDNF, NR1 and dental gyrus ( DG ) neurogenesis in rats with chronic stressed-depression and its possible mechamisms. Methods Chronic unpredictable mild stress was used to establish the rat model of stressed depression. The expression of BrdU, NeuN, brain -derived neurotro-phic factor ( BDNF ) and N-methyl-D-aspartate recep-tor1 ( NR1 ) in hippocampal dental gyrus were detected by fluorescently labeled immunohistochemical method. In addition, BDNFmRNA was detected by in situ hy-bridization. Results Chronic stress could inhibit the proliferation of neural precursors in hippocampal DG ( P<0. 01 );the expression of BDNF decreased signifi-cantly in DG in model rats ( P <0. 01 ) , while the ex-pression of NR1 increased significantly ( P <0. 01 ) . JWSNS and Fluoxetine hydrochloride significantly en-hanced the amount of new proliferating cells and the number of neurons in unit area of DG ( P<0. 01 ) , in-creased the expression of BDNF ( P <0. 01 ) and de-creased the expression of NR1 in DG(P<0. 01). Con-clusion JWSNS could promote the neuronal prolifera-tion in hippocampal DG of rat with chronic stressed-de-pression,and may exert an effect of promoting the pro-liferation of neurons in hippocampal DG by enhancing the expression of BDNF and decreasing the expression of NR1 .
