Background Gingerol is the generic term for pungent constituents in ginger, which has been reported to be effective for inhibiting vomiting. We attempted to investigate the antiemetic effect of gingerol and its effective mechanism on substance P and NK1 receptors in minks. Methods The antiemetic effect of gingerol was investigated during a 6-hour observation on a vomiting model in minks induced by cisplatin, （7.5 mg/kg, intraperitoneal）. The distribution of substance P and NK1 receptors in the area postrema and ileum were measured by immunohistochemistry, and the expression of NK1 receptor in the area postrema and ileum were measured by Western blotting. Results The frequency of cisplatin induced retching and vomiting was significantly reduced by pretreatment with gingerol in a dose-dependent manner （P 〈0.05）. Substance P-immunoreactive was mainly situated in the mucosa and submucosa of the ileum as well as in the neurons of the area postrema. The immunoreactive production of NK1 receptor was mainly situated in the muscular and submucosa of ileum and the neurons of area postrema, gingerol markedly suppressed the increased immunoreactivity of substance P and NK1 receptor induced by cisplatin in a dose-dependent manner （P 〈0.05）, and exhibited effective inhibition on the increased expression levels of NK1 receptor in both the ileum and area postrema dose-dependently （P 〈0.05）. Conclusions Gingerol has good activity against cisplatin-induced emesis in minks possibly by inhibiting central or peripheral increase of substance P and NK1 receptors.

目的评价聚乙二醇干扰素α-2a与普通干扰素治疗HBeAg阳性慢性乙型肝炎的疗效。方法计算机检索MEDLINE、EBSCO、PubMed、CNKI、万方数据库等,并追查了所有纳入文献的参考文献。检索年限均从建库到2009年5月。纳入聚乙二醇干扰素α-2a与普通干扰素比较治疗HBeAg阳性慢性乙型肝炎的随机对照试验。采用Jadad评分法评价纳入研究的方法学质量,并用Cochrane协作网提供的RevMan5.0软件进行Meta分析,并根据疗程和观察时间的不同进行亚组分析。结果纳入6个随机对照试验(n=688),其中4个研究疗程为48周,2个研究为24周,我们按疗程进行了亚组分析。Meta分析结果显示,聚乙二醇干扰素(180ug/d,48周)HBeAg阴转率、HBV-DNA阴转率、HBeAg血清转换率、ALT复常率均高于普通干扰素组,差异有统计学意义(P0.05)。结论48周疗程的聚二乙醇干扰素效果优于普通干扰素,24周疗程的聚二乙醇干扰素在HBV-DNA阴转率方面优于普通干扰素,其他方面与普通干扰素相当。但由于纳入研究的方法学质量均不高,故上述结论在临床使用时应谨慎考虑。
