The mechanism of PPS accelerating IEC-6 cells migration was also researched with gene-chip technique. The Altas Clontech Rat cDNA Chip which consisted of 1176 spots representing different functional categories such as heat shock/stress, cell cycle, transcription factors, hormones, metabolism, etc was used. Result showed in cell migration model of IEC-6 cell line, compared with control group, expression of 38 genes in total 1176 genes varied in cells treated by PPS, including 21 genes up-regulated and 17 genes down-regulated. Date analyze showed the mechanism of PPS accelerating IEC-6 cells migration mainly related with promoting the numbers and activity of cellular ion channel, especially 〓 channel.

从以上实验结果中我们可以得出以下结论：四君子汤总多糖具有促进IEC-6细胞增殖、迁移、粘附的作用；四君子汤总多糖无论是对IEC-6细胞增殖、或者迁移的作用均优于各单味药多糖，可能是各种单味药多糖综合作用的结果；多糖可能是四君子汤"益气健脾"药效的主要成分；小肠上皮细胞可能是四君子汤总多糖的作用靶点之一，提示临床采用四君子汤及"益气健脾"法治疗"脾虚证"的疗效机制可能与增强机体的整体免疫和肠道粘膜免疫功能有关。

Then studied on several clays affect on the stability of ferrate solution. The results show the addition of clays retarded the decomposition of ferrate in alkaline solution. Through analysed the results of test, we found this due to the silicium or polysilicium of clays and its increasing stabilizing effect on ferrate when the concentration of silicium or polysilicium increases.

接着作了粘土对高铁酸盐溶液的稳定作用的研究，结果表明粘土对高铁酸盐溶液有良好的稳定作用，通过实验分析得到其稳定作用是由于粘土中溶出的硅酸根或多聚硅酸根所致，且随着其浓度的增加对高铁酸盐的稳定作用增强。

objective we start with clinical research to explore the ability and mechanism of ion conduction with chinese herbs to curing ovulatory obstacle.methods adopting the methods of clinical observation random contrast.select the cases of ovulatory obstacle dividing randomly into two groups:therapeutic group and control group,the patients of therapeutic group using ion conduction with chinese herbs with act'on nourishing blood and promoting blood circulation to dissipate blood stasis when follicle grow up to 1.4cm.we take the decoction of jia jian tao hong si wu tang conducting the unilateral lower abdomen which has the dominant follicle,treating continuously for 4～8 days and observing ovulation.the patients of control group inject hcg 10000unit when follicle grow up to 1.8cm and observing ovulation.appraising two groups ovulated rate and pregnancy rate,and detect fsh、lh、e2、p at sixteen to eighteen days of menstrual cycle.results ion conduction with chinese herbs can significantly inspires ovulation and its effection is evidently higher than control group and has a higher pregnancy rate,no side effect of ovarian hyperstimulation syndrome.conclusion ion conduction with chinese herbs has significant function on inspiring ovulation.the target effection of treating ovulatory obstacle is exact.this method has a ovulated rate and higher pregnancy rate.

采用临床观察、随机对照的方法，选择排卵障碍的患者，随机分为治疗组和对照组，治疗组在b超监测卵泡生长达到1.6cm时，给予具有养血、活血化瘀作用的加减桃红四物汤水煎剂，用离子导入仪将中药水煎剂导入有优势卵泡的一侧少腹部，连续治疗4～8时天，同时连续监测卵泡排出情况。对照组在b超监测卵泡达到1.8cm时，开始采用hcg10000u肌注，连续b超监测卵泡排出情况。评价两组排卵率及受孕率，同时在月经周期的第16～22天抽血查fsh、lh、e2、p。结果运用离子导入的方法将具有促排卵作用的加减桃红四物汤水煎剂导入有优势卵泡的一侧附件，其促排卵的作用优于用hcg肌注促排卵，而且受孕率高，无卵巢过激综合征之虞。结论中药离子导入具有显著的促排卵作用，其治疗排卵障碍的靶向作用确切，排卵率及受孕率高。

The studies on metabolic enzymes、synergists and neurobioassays suggest that the monooxygenases、esterase and decreased nerve sensitity are involved in resistance to pyrethroids in the resistant HJ-R strain . The resistance to both organophosphorus and carbamate insecticides is mainly caused by metabolic mechanisms. The significantly synergistic effects of Pbo infer that the resistance to carbamata may be principally attributable to monooxygenases detoxification.

代谢酶系、增效作用以及神经电生理研究表明，HJ-R种群对拟除虫菊酯类杀虫剂的抗性是由多功能氧化酶及酯酶代谢增强、神经敏感性降低几个因子综合作用的结果；对有机磷、氨基甲酸酯类杀虫剂的抗性主要是由代谢机制引起，与靶标部位敏感性降低机制抗性无关，Pbo对HJ-R种群突出的增效作用，表明多功能氧化酶代谢在对灭多威的抗性中可能起主导作用。
