This article was aimed to study on clinical application of Shanyao (Dioscorea opposita Thunb.) in each historical period, which can offer some suggestions for clinical doctors to use Shanyao correctly. A total of 668 pieces of formulae containing Shanyao were recorded from the classic format Dictionary of Traditional Chinese Medicine Formula. And then, statistic analysis was made on the emerging frequency according to its effect. The results showed that different effects of Shanyao started to be widely applied from the Song dynasty. It was most widely applied in the Ming and Qing dynasty. Nowadays, the difference between using Shanyao has been gradually decreased. During the whole historical period, clinical functions of Shanyao are mainly reinforcing the spleen and the stomach, tonifying the kidney and strengthening yin. However, clinical functions of reinforcing the kidney and restraining yin, tonifying the lung and promoting fluid are used secondly. It was concluded that the research analyzed clinical application of Shanyao in each historical period, which can offer scientific basis for clinical practice and health maintenance with the using of Shanyao.

This article was aimed to study the effect of resveratrol on steroid-induced diabetes mellitus (SDM) in rats and the related mechanism. SD rats were randomly divided into the normal control (NC) group, SDM group, low dosage of resveratrol (LDR) group, middle dosage of resveratrol (MDR) group, and high dosage of resveratrol (HDR) group. All groups were tested on the change of blood glucose, insulin resistance (IR), adiponectin and tumor necrosis factor-α(TNF-α) in serum. The rate of cellular apoptosis in pancreas islet and the expression of BCL2 in rats were also observed. The results showed that compared with the SDM group, the blood sugar, IR, TNF-αlevel, and the ratio of pancreas islet cellular apoptosis in serum of the MR group and HDR group were lower (P<0.05). The expres-sion of adiponectin and BCL2 protein were up-regulated in the MR group and HDR group (P<0.05). It was conclud-ed that resveratrol can protect rats against the injury from MDR and HDR of SDM. This protective effect is possibly mediated by down-regulating the blood glucose, IR, inflammation factors in pancreas islet, and up-regulation of BCL2 protein, in order to inhibit cellular apoptosis in pancreas islet.

Objective To evaluate the role of autophagy in apoptosis in cortical neurons of rats in the early phase of oxygen-glucose deprivation (OGD).Methods Female Sprague-Dawley rats at 16-18 days of gestation,weighing 350-400 g,were sacrificed after being anesthetized with pentobarbital sodium.The fetal rats were obtained and the primary cortical neurons were isolated and seeded in culture plates.The neurons were then divided into 4 groups (n =7 each) using a random number table:control group (group C),OGD 30 min group,OGD 1 h group,OGD 2 h group,and OGD 3 h group,OGD + autophagy inducer rapamycin group (OGD + R group),and OGD + autophagy inhibitor 3-methyladenine (3-MA) group (OGD + 3-MA group).The neurons were incubated in sugar-free DMEM medium containing 5％ CO2 and 95％ N2 for 30 min,1,2 and 3 h in OGD 30 min,1 h,2 h,and 3 h groups,respectively.Rapamycin (final concentration of 100 nmol/L) and 3-MA (final concentration of 10 mmol/L) were added to sugar-free DMEM medium in OGD + R and OGD + 3-MA groups,respectively,and the neurons were then incubated for 1 h.The CCK-8 assay was used to detect the neuronal viability after the end of OGD.The expression of caspase-3 and LC3 Ⅱ was measured by Western blot.Results Compared with C group,the survival rates of cortical neurons were significantly decreased in the other groups,the expression of LC3 Ⅱ was up-regulated in OGD 30 min,1 h,2 h and 3 h groups,no significant change was found in caspase-3 expression in OGD + R group,and the expression of caspase-3 was up-regulated in the other groups.Compared with OGD 1 h group,the survival rates of cortical neurons were significantly decreased in OGD2 h,OGD3 h and OGD + 3-MA groups,the survival rates of cortical neurons were increased,and the expression of caspase-3 was down-regulated in OGD + R group,the expression of LC3 Ⅱ was up-regulated in OGD + 3-MA group,and the expression of LC3 Ⅱ was down-regulated in OGD2 h and 3 h groups.Conclusion Autophagy initiated in the early phase of OGD can inhibit apoptosis in cortical neurons of fetal rats.
