Objective To investigate the effect of nimodipine (ND) injecting into cisterna magna on the mitochondrial pathway in hippocampus in rabbit model of subarachnoid hemorrhage (SAH). Methods Eighteen New Zealand white rabbits were randomly allocated to Sham group, SAH group and ND group, six in each group. All the animals underwent operation under anaesthesia. One mL/kg autologous non-heparinized arterial blood was injected into cisterna magna in SAH group and ND group, and the same dosage of saline was injected into cisterna magna in Sham group. Thirty minutes after injection, 1 mg/kg nimodipine was injected into cisterna magna in ND group, and equal-volume of saline was injected into cisterna magna in Sham group and SAH group. All the animals were assessed for the grade of food intake and neurological impairment, and rats were killed 72 hours after SAH. Their hippocampus were processed for detecting the expressions of Bcl-2, Bax, Caspase-3 and Cyt-C mRNA by qRT-PCR. The protein expressions of Caspase-3 and Cyt-C were detected by Western blot assay. Results Compared with the Sham group, there were lower grade of food intake, varying degrees of neurological impairment and lower ratio of Bcl-2/Bax, while the mRNA levels of Bcl-2, Bax, Caspase-3 and Cyt-C and protein levels of Caspase-3 and Cyt-C showed elevated expressions in SAH group and ND group (P<0.05). Compared with SAH group, there were no significant differences in the score of food intake and neurological impairment in the ND group ( P>0.05). There were higher ratio of Bcl-2/Bax and expression levels of Bcl-2 mRNA and lower expression levels of Bax mRNA, Caspase-3 and Cyt-C mRNA and proteins in ND group than those in SAH group (P<0.05). Conclusion Nimodipine plays a protective role in inhibiting the activity of mitochondrial pathway in hippocampus after subarachnoid hemorrhage.

Objective Adsorption effect of dietary fibers from seaweeds on extrinsic estrogens was studied.Methods The methods included the tests in vivo and in vitro which simulated environments of stomach and small intestine of rat. Results The adsorption effect of four kinds of dietary fibers on estradiol in simulated environments of small intestine was better than that in simulated environments of stomach. The effect of Laminaria japonica was the best. And the rate of adsorption on estradiol was 108 g?g~ -1.It is 1.5,1.8, 3.1, and 3.0 times that of Sargassum,wheat blan,Gracilaria and Eucheuma,respectively. The rates of adsorption on estradiol of four kinds of dietary fibers from Gracilaria, Eucheuma, Sargassum and laminaria japonica was 11.1%,13.6%,27.5% and 38.7%, respectively. Adsorption rate of Sargassum and laminaria japonica was 1.9 and 1.3 times than that of wheat bran, respectiveiy which was 20.4%. While for Gracilaria and Eucheuma, adsorption rate was lower than that of wheat bran. Conclusion The dietary fibers from four seaweeds showed adsorption effect on extrinsic estrogens. The dietary fibers from brown seaweeds (Sargassum and laminaria japonica) had more adsorption effect than that of red seaweeds (Gracilaria and Eucheuma).

Objective To investigate the clinical effect of nicorandil for treatment of patients with acute respiratory distress syndrome (ARDS).Methods A prospective randomized controlled trial was conducted. A total of 40 cases of patients with ARDS admitted to Department of Critical Care Medicine of Guizhou Provincial People's Hospital from October 2012 to October 2014 were enrolled, and they were randomly divided into two groups, 20 cases in each group. The two groups were treated with routine western medicine after admission. On this basis, the observation group was given nicorandil 10 mg, while the control group was given warm boiled water 10 mL, through gastric tubes 3 times a day, the therapeutic course being consecutive 5 days in both groups. The length of stay in intensive care unit (ICU), duration of mechanical ventilation after treatment, oxygenation index (OI), alveolo-arterial oxygen partial pressure difference (PA-aO2), positive end-expiratory pressure (PEEP), acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score, Glasgow coma score (GCS) before and after treatment, the predicted death rate (PDR) and 28-day mortality were compared between the two groups. The predicitive factors for 28-day mortality were screened by binary logistic analysis.Results The length of stay in ICU and duration of mechanical ventilation of control group were longer than those of observation group, but the difference was not statistically significant [ICU length of stay (day): 14.55±12.71 vs. 9.15±6.00, duration of mechanical ventilation (day): 13.25±12.27 vs. 7.75±5.32, bothP > 0.05]. After treatment, the GCS was higher than that before treatment in control group and observation group (11.95±3.98 vs. 10.75±4.89, 12.95±3.67 vs. 12.20±4.56), while APACHE Ⅱ score, PDR and PEEP were all lower than those before treatment [APACHE Ⅱ: 21.05±8.58 vs. 24.90±5.63, 18.70±11.21 vs. 26.65±7.67; PDR: (47.71±29.49)% vs. (61.00±23.29)%, (36.79±18.49)% vs. (56.12±18.16)%; PEEP (cmH2O, 1 cmH2O = 0.098 kPa): 4.40±3.14 vs. 5.75±2.59, 3.80±2.55 vs. 7.55±3.32], but there were no statistically significant differences between the two groups before and after treatment (allP > 0.05). After treatment, the OI was significantly higher and the PA-aO2 was significantly lower than those before treatment in the two groups, and the degrees of improvement of the observation group were more remarkable than those of the control group [OI (mmHg, 1 mmHg = 0.133 kPa): 224.72±85.12 vs. 141.37±45.82, PA-aO2 (mmHg): 132.60±46.64 vs. 204.30±121.2, bothP < 0.05]. The 28-day mortality of observation group was lower than that of control group, but no statistically significant difference was seen [15% (3/20) vs. 25% (5/20),χ2 = 0.156,P > 0.05). Binary logistic regression analyses showed that the PA-aO2 [odds ratio (OR) = 0.958,P = 0.013, 95% confidence interval (95%CI) = 0.927 - 0.991], APACHE Ⅱ score (OR = 0.882,P = 0.010, 95CI = 0.803 - 0.970), GCS (OR = 1.399, P = 0.004, 95%CI = 1.111 - 1.761) and PDR (OR = 0.907,P = 0.002, 95%CI = 0.853 - 0.965) after treatment were the independent predictors of 28-day mortality.Conclusion Nicorandil can significantly improve oxygenation, but cannot reduce 28-day mortality in patients with ARDS.
