AIM:To observe the protective effect of allitridi on hippocampal neuron of rats with cerebral ischemia-reperfusion (I/R) injury and to investigate its effects on P53 expression in hippocampus.METHODS: The global cerebral ischemia-reperfusion models were established by 4-vessel occlusion. Allitridi at doses of 10, 20 or 30 mg/kg was injected through rat’s tail vein, half dose at 30 min before brain ischemia and another half dose at 10 min after reperfusion were injected, respectively. The hippocampus of rat was removed 24 h after reperfusion. Toluidine blue staining was applied to estimate morphologic changes. Flow cytometry was used to evaluate neuronal apoptosis rate of hippocampus. Immunohistochemistry was used to observe the expression of P53 protein.RESULTS: Compared with sham group, survival neuronal density in I/R group was significantly depressed. The rate of neuronal apoptosis and the expression of P53 protein were significantly increased. Allitridi significantly increased the number of survival neurons in hippocampus compared to I/R group. Meanwhile, allitridi remarkably inhibited the rate of neuronal apoptosis and the expression of P53 protein.CONCLUSION: Allitridi has protective role against brain ischemia reperfusion injury. The mechanism may be involved in blocking P53 protein expression in hippocampus of rats with ischemia-reperfusion.

Objective To evaluate the clinical efficacy of oral taking traditional Chinese medicine with functions of tonifying kidney, nourishing blood and soothing liver and external application treatment of premature ovarian failure(POF). Methods 40 patients of deficiency of liver-yin and kidney-yin type POF in Gynecology Department of Xiyuan Hospital CACMS from July 2009 to July 2013 were collected and administrated with traditional Chinese medicine with functions of tonifying kidney, nourishing blood and soothing liver and external treatment for 3 months. The changes of menstruation situation, symptoms and serum sex hormone were compared before and after the treatment. Results ① Menstruation integral were reduced after the treatment, showing a statistical significance compared with those before the treatment(t=5.694,P<0.01). ② Symptoms integral were reduced after the treatment, showing a statistical significance compared with those before the treatment(t=21.828,P<0.01). ③ Serum FSH, LH were decreased and Serum E2 were increased after the treatment,showing a statistical significance compared with those before the treatment(P<0.05). ④ The total effective rate was 92.5%(37/40). Conclusion Traditional Chinese medicine with functions of tonifying kidney, nourishing blood and soothing liver are effective for treating POF. These methods had proven to improve ovarian function by decreasing high level of FSH and LH, whereas enhancing the estrogen level, and therefore promote menstruation cycle.
