无孔的

Results1. The majority of patients with CNV were secondary to exudative AMD (69.10%); the minority was associated with CEC (17.60%), pathologic myopia (8.15%), choroiditis (3.86%), choroidal rupture (0.86%) and angiod streaks (0.43%) in descending order.

渗出型AMD患眼的PED裂孔最多见于PED的边缘(69.12%)，有裂孔发生的PED的角度和高度显著大于无裂孔者，而且以裂孔发生在边缘的PED的角度和高度更大。

材料与方法：选取200名不同年龄段无外伤、无神经症状和体征的受检者，进行多排螺旋CT薄层扫描，在计算机工作站上对获得图像进行多平面重建，获得相应截面图后，测量各相关指标，包括第3至第7颈椎(C_3-C_7)椎体横径、矢状径及高，椎体间隙，椎弓根的高与宽，冠状位钩突高度、钩突基底宽度、基底长、两侧钩突尖间距及基底长径角度，椎间孔高和宽，横突孔长和宽。按性别、年龄分组进行统计学分析。

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。

In the negative and interrogative forms, of course, this is identical to the non-emphatic forms.

。但是，在否定句或疑问句里，这种带有"do"的方法表达的效果却没有什么强调的意思。
