Objective To explore the effects of Xiefuzhuyu decoction on myocardial cellar apoptosis and expression of ICAM-1 gene protein in rats of experimental acute ischemic myocardium. Methods The left anterior descending coronary artery was ligated to make a model of acute ischemic myocardium. The changes in myocardial cellar apoptosis and the ICAM-1 gene expression were detected. Results The number of myocardium cellar apoptosis in Xiefuzhuyu group and Diaoxinxiekang group were significantly less than those of ischemic model group respectively. The number of myocyte necrotic cell increased in ischemic group. At the same time, the expression of ICAM-1 supported this condition. Conclusion Xiefuzhuyu decoction and Diaoxinxiekang can protect ischemic myocardium.

Objective To evaluate the control effect of comprehensive measures of schistosomiasis after its transmission in?terruption in Kaihua County,Zhejiang Province,so as to provide the references for further consolidation of schistosomiasis con?trol. Methods The data of Oncomelania hupensis snail survey and control,as well as environmental reform in Kaihua County were collected and analyzed from 1996 to 2015. Results From 1996 to 2015,totally 2 635 snail habitats and 102.75 hm2 area with snails were found,and 125.4 thousand snails were dissected and no one was schistosome infected. The accumulated snail control area was 4 932.98 hm2,and the area with snails was effectively reduced by the comprehensive control measures. Conclu?sion The schistosomiasis control effect could be consolidated by the comprehensive control measures emphasizing environmen?tal reconstruction,and the snail surveillance work still should be strengthened.

Objective To investigate the protective effects of round window membrane administration of dex-amethasone(Dex) on ototoxicity induced by gentamicin(GM) .Methods Sixty guinea pigs with normal hearing were randomly divided into four groups ,①GM group :treated with gentamicin by 120 mg · kg -1 · d-1 for 10 days;②GM -S-Dex group:treated as the GM group and dexamethasone by intraperitoneal injection 2 .5 mg · kg -1 · d-1 for 10 days;③GM -T -Dex group :treated as the GM group and dexamethasone by round window administration on right ear ;④NS -T -Dex group:treated with sodium chloride by 120 mg · kg -1 · d-1 for 10 days and with dex-amethasone topically as GM -T -Dex group .The auditory brainstem response (ABR) was respectively measured before the treatment and on day 1 ,day 10 after the treatment .After the treatment ,animals were killed instantly and the middle ear mucosa and the Corti's organ were observed with SEM .Results There was no change of ABR threshold in NS -T -Dex group on day 10 after the treatment ,whereas ABR thresholds in the other groups were elevated and GM group was the most significant .The massive outer hair cells loss was observed in GM group while the loss in GM -T -Dex group and GM -S-Dex group was trivial .The middle ear mucosa was normal and no inflammation was found in any of the groups .Conclusion The results indicated that round window administration of dexamethasone had protective effects aganist the gentamicin -induced hearing loss .

Objective To investigate the effects of mild hypothermia on the expression of Dickkopf-1(Dkk1)in rats'brains after focal cerebral ischemia and reperfusion and to explore the molecular mechanism of any neuroprotective effects of mild hypothermia. Methods A focal cerebral ischemia and reperfusion model was established in rats by intraluminal filament occlusion of the middle cerebral artery.The adult rats were randomly divided into four groups:a sham-operation group,a sham-operation plus mild hypothermia group,a model group,and a model plus mild hypothermia group.The expression of Dkk-1 mRNA and protein in the ischemic cortex at different phases afterreperfusion were assessed using a reverse transcription polymerase chain reaction(RT-PCR),Western blotting and immunohistochemical staining.Results There was little expression of Dkk-1 mRNA or its protein in the sham-operation group or in the sham-operation plus mild hypothermia group.Expression of Dkk-1 mRNA and its protein began to increase after 2 h of cerebral ischemia and 3 h of reperfusion,with expression peaking at the 24th h after the start of reperfusion and then decreasing markedly.But expression was still stronger than in the sham-operation group at the 72nd h.At every reperfusion time point,expression of Dkk-1 mRNA and its protein were markedly less in the model plus mild hypothermia group than in the model group. Conclusion Dkk-1 probably participates in the pathologic process of injury caused by focal cerebral ischemia and reperfusion.Inhibiting the expression of Dkk-1 after focal cerebral ischemia and reperfusion is partly responsible for the neuroprotective effects of mild hypothermia.
