Objective: To investigate the protective effect of human lipoxin A4 (LXA4) on N2a cell damage induced by β-amyloid protein 25-35 (Aβ25-35) and the underlying mechanism. Methods: Aβ25-35 was used to treat N2a cells to establish Alzheimer's disease (AD) cell injury model. Meanwhile, LXA4 was added to the experimental group at different concentrations (50, 100 and 200 nmol·L-1 ). MTT assay was used to detect the activity of N2a cells. The apoptosis was detected by Hoechst 33258-PI staining, the expression of P62 and TRAF6 mRNA was detected by RT-PCR, and the expression of P62 and TRAF6 protein was detected by Western blot. Results: Compared with that of the model group, the cell survival rate of LXA4 protective group (50,100 and 200 nmol·L-1 ) increased (P <0. 01) and the apoptosis of N2a cells induced by Aβ25-35 was reduced by LXA4 (100 and 200 nmol·L-1 ) . Compared with that of the model group, the expression of P62-mRNA and protein-P62 of N2a cells treated with Aβ25-35 increased (P <0. 05 or P <0. 01) and the expression of TRAF6-mRNA and protein-TRAF6 of N2a cells treated with Aβ25-35 were reduced (P <0. 05 or P <0. 01). Conclusion: LXA4 has protective effect on N2a cell damage induced by Aβ25-35 , and its mechanism may be related to the up-regulation of P62 gene and down-regulation of TRAF6 gene.

OBJECTIVE: To investigate the effects of Erxian Decoction (EXD), a traditional Chinese compound herbal medicine and its separate prescriptions such as Wenshen Yijing Recipe (WSYJR, a recipe for warming kidney and replenishing essence), Ziyin Xiehuo Recipe (ZYXHR, a recipe for nourishing yin and dispersing fire) and Tiaoli Chongren Recipe (TLCRR, a recipe for regulating thoroughfare and conception vessels) and some extracts from EXD on the levels of LH and FSH in the primary cultured anterior pituitary cells from female rats. METHODS: EXD, its separate prescriptions and traditional Chinese herbal extracts from EXD were added directly to the incubators. The levels of LH and FSH were tested by radioimmunoassay. RESULTS: The levels of LH and FSH in the supernatant of anterior pituitary cells treated by EXD or its separate prescriptions including ZYXHR and TLCRR were increased significantly as compared with those in the blank control. There was a tendency for stimulating the secretions of LH and FSH in the WSYJR-treated group too. Dimethyl sulfoxide as the solvent of icariin and curculigoside could interfere with the results. CONCLUSION: EXD and its separate prescriptions such as ZYXHR and TLCRR can increase the levels of LH and FSH significantly.
