雌、孕激素受体和rasP~(21)蛋白的表达在乳腺癌预后中的意义

用酶联亲合组化法和ABC免疫组化法对93例乳腺癌石蜡标本中雌激素受体(ER)、孕激素受体(PR)和ras P~(21)蛋白进行了检测和对比研究。经果表明:ER、PR阳性率分别为64.52％和60.22％,经随访5年累积无瘤生存率阳性组高于阴性组(P<0.05);P~(21)蛋白的阳性表达率为52.69％,多出现在分化差的Ⅱ、Ⅲ级具有浸润性的乳腺癌组织中,随乳腺癌组织学分级的增加而增强,与ER水平呈负相关,5年累积无瘤生存率阴性组高于阳性组(P<0.05)。认为P~(21)蛋白表达的强弱同ER、PR一样反映了乳腺癌的生物学特性及预后。     

甲状腺癌和雌、孕激素受体的研究

利用酶联亲和组化法检测80例甲状腺良恶性肿瘤雌、孕激素受体（ER，PR）。结果显示：ER，PR阳性率与肿瘤良恶性、分化程度、性别有关。提示：ER，PR可作为甲状腺癌的一个生物学标记，有助于预后判断。ER是影响女性甲状腺癌发病率的一个重要因素，ER，PR阳性细胞可为进一步研究雌、孕激素对甲状腺肿瘤的作用机制提供一个线索。     

DETECTING LOW DENSITY LIPOPROTEIN RECEPTOR MUTANT GENE OF RABBIT BY PCR

Objective Watanabe Heritable Hyperlipidaemic （WHHL） rabbits with low density lipoprotein receptor （LDLr） gene mutation have provided unprecedented opportunities for the study of human atherusclerusis, in order to confirm LDL receptor gene status in rabbits, we developed a simple PCR technique to detect LDL mutations in rabbits. Methods Rabbits genomic DNA were extracted from ear biopsy, and amplified by PCR to detect 12 bp deletion mutation in WHHL rabbits. PCR products were directly digested with Bgl Ⅰ, and then applied to polyacrylamide gel electrophoresis. Results PCR products from homozygous LDLr ＋/＋ rabbits generated 2 bands of 212 and 94 bp after Bgl Ⅰ digestion, LDLr ＋/- rabbits generated 3 bands （294, 212, and 94 bp）, LDLr -/- animals, however, generated only 1 product （294 bp）. Conclusion This modified PCR method is simple and reliable.     

雌激素受体在肝海绵状血管瘤中的表达及意义

采用免疫组化Ｓ Ｐ法检测３０ 例肝海绵状血管瘤（Ｃａｖｅｒｎｏｕｓ ｈｅｍ ａｎｊｉｏｍ ａｏｆｌｉｖｅｒ,ＣＨＬ）组织中雌激素受体（Ｅｓｔｒｏｓｅｎ ｒｅｃｅｐｔｏｒ, ＥＲ）的表达,并以ＣＨＬ瘤旁正常肝组织作对照。结果ＥＲ 阳性表达于ＣＨＬ 血窦内皮细胞胞浆中,阳性率为４３３％ ;ＣＨＬ瘤旁正常肝组织中未见表达（ Ｐ＜ ０．０５）。提示肝海绵状血管瘤的生长与雌激素有关。雌激素可能通过其受体作用促进ＣＨＬ生长     

THE EFFECT OF FCγ RECEPTOR ON THE PATHOGENESIS OF GRAVES'' DISEASE

Objective To explore the roles of Fcγ receptor in the pathogenesis of Graves' disease. Methods Fcγ receptor gene knockout mice(Fcγ R KO mice) which were rooted in C57BL/6 mice and wild type C57BL/6 mice were immunized by hTSH receptor expressing cells (DAP3.WT).1-2×107 DAP3.WT cells were peritoneally injected into mice every two weeks for a total of six times.Two weeks after final immunization, mice were killed for measurement of total thyroxine,TRAb and pathological examination.Results The thyroxine level of the immunized Fcγ receptor gene knockout mice was significantly lower than that of the immunized wild type control mice (2.2±0.31 vs.3.32±0.59g·dL-1,P<0.05), but there was no significant difference between immunized Fcγ R KO mice and non-immunized wild type control group.The TRAb levels of the immunized Fγ R KO mice significantly increased compared to those of the immunized wild type mice (21.75±8.21 vs.14.11±6.21, P<0.05). The lymphocyte cells infiltration and destruction of thyroid follicles were found in the thyroid gland of the immunized Fcγ R KO mice. Conclusion　These results suggest that Fcγ receptor may be involved in the pathogenesis of Graves'disease.     

肺癌组织中性激素受体的研究

为研究肺癌与性激素及其受体之间的关系，运用酶联亲合组化法对53例肺癌组织中雌激素受体（ER）和孕激素受体（PR）进行了检测。结果：ER、PR阳性率分别为49．1％、54．7％，其阳性颗粒大部分位于癌细胞浆中（占58．2％）；早、中期患者的ER及PR阳性率较高；鳞癌PR阳性率（73．1％）高于小细胞癌（33．3％），腺癌ER阳性率较高，细胞分化好的ER阳性率较高（60％）。提示ER、PR存在于部分肺癌组织中，癌的发生和发展与性激素的影响有一定的关系。

非上皮源性卵巢肿瘤性类固醇激素受体的研究

采用Lee SH荧光组化法检测42例非上皮性卵巢肿瘤的雌激素受体(ER)和孕激素受体(PR)。结果显示:2/4例卵胞膜细胞瘸有ER、PR;6/8例颗粒细胞瘤有ER、PR,其中4倒受体水平较高;12/16例畸胎瘤有ER、PR,畸胎瘤中含柱状上皮、皮脂腺、汗腺、软骨时,显示较高的ER、PR水平。内胚窦瘤、无性细胞瘤及纤维瘤均显示受体阴性。1/4例胃肠道转移癌有ER、PR阳性细胞。结果提示,应重视颗粒细胞瘤ER、PR的检测,对受体阳性的肿瘤患者,也许可进行激素治疗。
