Based on these previous work, in this research, in order to explore the the molecular mechanism of enhanced tumor cell immunogenicity treated by elemene and mytomycin C compositely, we used murine Hca-F ascitic hepatic carcinoma ( high lymphatic metastasis substrain of H22) as an experimental model to compare the immunoprotective effects on Hca-F cells as well as the mechanism of the effects caused by HSP70-peptide complex purified from untreated tumor cells, EC-TCV and BCG; We studied the mechanism of increased tumor cell membrane HSP expression treated with elemene by the techniques of RT-PCR and immunoelectron microscopy; In order to deeply elucidate the antitumor effects and the molecular mechanism of elemene in increasing tumor cell immunogenicity we analyzed and compared the effects of elemene and heat shock on the gene expressions of tumor cell using gene expression profile chip.

本论文在上述研究成果的基础上，选择小鼠肝癌H22的高淋巴道转移亚系Hca-F为模型，进一步比较了未处理肿瘤细胞来源、榄香烯复合瘤苗来源的和卡介苗来源的HSP70-肽复合物对Hca-F的免疫保护效应、效应机制，探讨榄香烯-丝裂霉素复合处理增强肿瘤细胞免疫原性的分子机制；以Hca-F和人肝癌细胞株HepG〓等为模型研究了榄香烯处理增强肿瘤细胞膜热休克蛋白表达的机制；以HepG〓为模型用表达谱基因芯片研究比较了榄香烯与热休克处理对肿瘤细胞基因表达的影响，从而进一步阐明榄香烯抗肿瘤作用及增强肿瘤细胞免疫原性的分子机制。

In the implementation of this system, All the functions of Microsoft NetMeeting are integrated seamlessly by using Microsoft NetMeeting COM. In this system, the transmission and the share of information are reunited according to the actual needs. It solves the incompactness between NetMeeting and medical system, and also avoids much research work in redeveloping lower level network service in this way. It reduced the periods of software development and improved the reliability of this system by using mature module.

本系统在实现过程中利用Microsoft NetMeeting COM组件将Microsoft NetMeeting的所有功能无缝的纳入到本远程医疗会诊系统中，并按实际需要重新组织信息的传递与共享，既解决了视频会议系统与医疗系统结合不紧密的问题，又避开了重新开发网络底层服务的大量工作，大大节省了系统的开发周期，而且借用成熟的系统模块也大大提高了系统的可靠性。
