肾细胞癌伴静脉癌栓15例临床分析

１９８５～１９９４年治疗肾细胞癌伴静脉癌栓１５例。按癌栓水平分为肾型１０例，肝下型４例，肝上型１例。Ｂ超和ＣＴ检查总确诊率７３％。手术１４例均完整取出癌栓，术后１３例接受５－ＦＵ加ＭＭＣ方案化疗。随访３个月～５年，１例肝下型和２例肾型无瘤存活分别３６、４３、５２个月，余均在术后２年内死亡。认为Ｂ超与ＣＴ互补应用可基本确诊静脉癌栓，除肝上型和已有血管壁浸润者外大部分癌栓可采用松解游离同时渐渐拉出的方式取出，癌栓水平除肝上型外对预后影响不大。

Study on lymphocyte activation and proliferation induced by anti-CD3 McAb

Summary T cell activation and proliferation via CD₃-TCR complex were investigated by lymphocyte DNA synthesis in vitro. Several interfering factors were also discussed. The result indicated that lymphocyte activation and proliferation are calciumdependent. A rise of cytoplasmic free Ca²⁺ quickly following activation with CD₃ McAb is mainly due to intracellular mobilization of Ca²⁺, while lymphocyte proliferation needs both intracellular mobilization of Ca²⁺ as well as influx of extracellular Ca²⁺. It was confirmed that CTX sensitive G protein plays a role in regulating T cell proliferation by pretreatment with CTX suppressing lymphocyte³H-TdR incorporation obviously. PLC and PKC inhibitor neomycin and P. S. S could also decrease T cell proliferation.     

凝集素受体在膀胱癌中的分布

目的：探讨膀胱癌中凝集素受体分布与其分化程度和浸润深度的关系。方法：应用生物素标记的花生凝集素（ＰＮＡ）、麦胚凝集素（ＷＧＡ）及刀豆凝集素（ＣｏｎＡ）等３种凝集素对５２例人体膀胱癌、１０例正常人体膀胱粘膜，进行亲合组织化学法研究。结果：发现正常膀胱粘膜ＰＮＡ、ＷＧＡ受体阴性，ＰＮＡ受体阳性率随膀胱癌病理分级的上升而递增，差异具有显著性意义（Ｐ＜０．０５）。ＰＮＡ、ＷＧＡ受体阳性率在浸润性肿瘤中明显高于浅表性肿瘤（Ｐ＜０．０５）。结论：提示ＰＮＡ、ＷＧＡ受体阳性率与膀胱癌分化程度和浸润深度有关。
