%X Objective. To investigate the effect of isoflurane (ISO) on the proliferation, apoptosis, and inflammatory response of lipopolysaccharide- (LPS-) induced normal human astrocytes (NHAs) by regulating the miR-206/BDNF axis. Methods. NHA proliferation activity was measured by MTT; NHA apoptotic rates were measured by Annexin V-FITC/PI; western blotting was used to measure the BDNF expression; ELISA was used to measure the IL-6, IL-1¦Â, and TNF-¦Á expression in NHAs; qPCR was used to measure the expressions of miRNAs that are related to NHAs proliferation and apoptosis; dual-luciferase reporter was constructed to validate the targeting relationship between miR-206 and BDNF. Results. LPS increased the proliferation activity and decreased the apoptosis rate of NHAs which were effectively reversed by the ISO ( ); LPS significantly inhibited the expression of miRNAs related to proliferation and apoptosis in NHAs ( , ), whereas ISO significantly increased the expression of miR-206 ( ) by downregulating the expression of BDNF, thus inhibiting NHA proliferation and inflammatory response and enhancing apoptosis. Conclusion. ISO can inhibit the expression of BDNF by upregulating the expression of miR-206, thereby inhibiting the proliferation and inflammatory response of NHAs and promoting its apoptosis
