Part II The experiment study on anti-tumour effect of dendritic cells derived from peripheral blood monocyte of patients with oral cancer after pulsed by tumour antigen in different ways. Collected 50ml peripheral blood from each patients and volunteers to induced DC in vitro. We parted the test group and control group into three subgroups respectively, untreated group A, freezed and thawn group B, RNA transfected group C. To group A, after induced DCs for five days , we added 200U/mlTNF-α in each hole and cultured on. To group B, we added protein antigen (DC/ tumor cells = 1 : 1 ,each hole) for 4h at 5d, and then added 200U/mlTNF-α in each hole and cultured on. To group C, transfected immature DC with tumor cell RNA(DC:RNA=1×105/ml: 5ug)at 5d, operated completely with the specification of invitrogen DMRIE-C reagents. After transfection we replaced transfection agent with complete medium, and then added 200U/mlTNF-α in each hole and cultured on.

第二部分口腔癌患者外周血来源的树突状细胞体外负载抗原后抑瘤作用的实验研究无菌采集20例口腔癌患者和20例健康志愿者外周血50ml，分离单个核细胞体外诱导培养DC，并将实验组和对照组细胞各分为三组，A组为未处理组，B组为冻融组，C组为RNA转染组。A组DC在培养5d后，每孔加入TNF-α200U/ml；B组DC培养第5d后，每孔中加入癌细胞蛋白抗原，使DC/肿瘤细胞=1：1，继续培养4h后，每孔加入TNF-α200U/ml；C组将培养至第5d的未成熟DC用肿瘤细胞RNA进行转染(DC：RNA=1×105/ml： 5ug，按照invitrogen DMRIE-C试剂说明书进行操作)，转染结束后用完全培基取代转染剂，每孔加入TNF-α200U/ml。

China cure learns abnormal reaction to learn branch secretary-general, Beijing assist with hospital allergy Yin Jia of response division director is being accepted " life times " when interviewing, express, the person of now fruit allergy is absent a few, the fruit allergy of most nevertheless person reacts the symptom is lighter, the unwell feeling with urticant hemp of occurrence oral cavity or oral cavity mucous membrane and labial oedema, general 9 hours can disappear.
