Objective To determine whether fetal rats exposure to isoflurane will cause postnatal learning and memory deficits,and change Bcl-2/Bax ratio in the hippocampus CA1 and retrosplenial cortex in fetal brain of rats. Methods Twenty-eight Sprague Dawley pregnant rats at gestation day 21 (E21) were randomly divided into isoflurane treatment group(n=14) and sham control group(n=14). Rats in isoflurane treatment group were ex-posed to 1.3% isoflurane in a carrying gas of 30% oxygen, balance nitrogen for 6 h in a warmed, humidified cham-ber. For sham control group,animals were treated at the same condition with only carrying gas. In behavior study,the spatial learning and memory ability at juvenile ages was determined with the Morris Water Maze(MWM). In immunohistochemistry study,changes of Bcl-2 and Bax expression in hippocampus CA1 and retrosplenial cortex in the fetus brain after isoflurane treatment at 2 hours was performed by using immunofluorecence staining.Results In the MWM training, the escape latency to platform in the place trials showed no significant difference between the two groups,but the postnatal rats in 1.3% isoflurane group showed obviously improved retention of memory by spending more percentage of time swimming in the probe quadrant as compared to the control animals ((42.33±2.31) s vs (33.2±2.15) s, t=2.21, P<0.05) in the probe test. Compared to controls, 1.3% isoflu-rane exposure for 6 h to the pregnant rats increased the intensity of Bcl-2, decreased the intensity of Bax, and sig-nificantly increased the Bcl-2/Bax ratio in the fetal hippocampal CA1 region (4.40±0. 86 vs 1.31±0.32, t=3. 378, P<0.01) and the fetal retrosplenial cortex (5.07±1.27 vs 1.47±0.48, t=2.656, P < 0.05) respec-tively. Conclusion 1.3% isoflurane exposure in pregnant rats significantly improves the spatial retention memo-ry of their rat pups at a juvenile age and increases the Bcl-2/Bax ratio in the hippocampal CA1 region and the ret-resplenial cortex in the fetal rat brains.

Objective: To explore the mechanisms of acupuncture in improving osteoporosis. Methods: In this study, the expression of OPG and BMP-2 proteins of femur in SAMP6 control group, SAMP6 acupuncture group, SAMP6 sham-acupuncture group and SAMR1 control group were determined by Western Blot technique. Results: Compared with SAMR1 control group, the expression of OPG and BMP-2 proteins of the femur in SAMP6 control mice decreased obviously. Acupuncture could stimulate the expression of OPG and BMP-2 and no differences were detected between the SAMR1 control group and SAMP6 acupuncture group. Conclusion: Osteoporosis observed in SAMP6 was correlated with low expression of OPG and BMP-2. After acupuncture treatment, both of them showed increased expression, it suggested that the curative effects of acupuncture on osteoporosis were partly due to stimulating skeleton formation, inducing the production of some local factors of bone metabolism and decreasing the bone turnover rate.
