The hypermethylation of 5 CpG in promoter region serves as a mechanism of the inactivation of RASSF1A gene. This mechanism has been widely confirmed in multiple tumorgenesis including prostate carcinoma cell line DU145. Object Our study is to disclose the epigenic mechanism of the carcinogenesis of prostate cancer. Including: 1. We use demethylation agents in combination with chemotherapeutic drugs, to disclose whether demethylation agents can enhance the anticancer effect of chemotherapeutic drugs. 2. to study whether demethylation drugs can affect the methylation level of RASSF1A gene in.

目的 本研究旨在探讨前列腺癌的表遗传学发生发展机制，包括： 1、甲基化抑制剂与多种化疗药物联合应用，探讨二者间的协同作用，增强化疗药物疗效； 2、体外应用甲基化抑制剂对前列腺癌细胞DU145的RASSF1A基因甲基化水平的影响； 3、体外应用甲基化抑制剂对前列腺癌细胞DU145的RASSF1A基因及蛋白表达的影响，以期为进一步深入探索通过改变抑癌基因的甲基化而为前列腺癌发生机制和基因治疗提供有意义的数据和理论依据。

Methods: Mice were inoculated with tumor cells. Inhibitory effect of transfection with pCH510 on murine tumor origined from different inoculative dose and inhibiting effect of immediate transfection pCH510 after chemotherapy on tumor were observed, respectively. By cell culture technique, the influence of chemotherapeutic drug to activation of marcrophages and lymphocytes after i.p. injection of drug was observed. By cell counting method, the kinetics of the change of number of peripheral blood immunocytes induced by administration of chemotherapeutic drug was observed. The inhibitory effect of transfection with pCH510 five days after chemotherapy on murine tumor was observed.

采用瘤细胞接种建立小鼠肿瘤模型：通过基因转染，观察pCH510对不同接种量所形成的小鼠肿瘤的抑制作用以及小鼠肿瘤化疗后立即进行pCH510转染的抑瘤效果；采用细胞培养技术，观察小鼠体内注射化疗药物后，其对小鼠腹腔巨噬细胞和脾淋巴细胞激活功能的影响；采用细胞计数的方法，观察化疗药物所致小鼠腹腔巨噬细胞和外周血免疫细胞数量变化的动力学；另外小鼠肿瘤化疗后第5天进行pCH510转染，观察抑瘤效果。

The treatment of leukemic cell with a longterm, intermittent,singular, unefficient chemotherapeutic agents could induce multi-drug resistant cells. Interleukin-4 can reverse the multi-drug resistance by inhibiting the expression of p-gp and increasing the quantity of intracellular chemotherapeutic agents in tumor cells. The effects were probably related to the inhibition of the PKC activity.

长期、间断、单一、不足量的化疗可导致 MDR；IL-4 可通过抑制肿瘤细胞的 p-gp表达，增加化疗药物在肿瘤细胞内的聚集而逆转白血病细胞的MDR，此作用可能与抑制 PKC的活性有关。

Cynanchum Lingtai apricot production in the average weight 65 grams, the brightly-colored fruit, juicy rich, sweet-sour taste, sweet from the nucleolus, when the late Qing Dynasty famous Shaanxi, Gansu provinces, the Qing imperial court Tongzhi tribute for years.

灵台生产的牛心杏平均单果重65克，果实色泽鲜艳，汁多味浓，甜酸适口，离核仁甜，清末时就驰名陕、甘两省，清同治年间曾为朝廷贡品。

Chenopodium album,Solanum nigrum, and Amaranthus retroflexus were very susceptible to the herbicides. Polygonum persicaria and Abutilon theophrasti were relatively less susceptible to the herbicides, and Lycopersicon esculentum was not susceptible to it. The relationship between reduction rates of weed biomass and PPM values of weed leaves 2,4, and 6 days after treatment was established.
