【Abstract】Objective:To investigate the expression and significance of gene survivin and vascular endothelial growth factor (VEGF) in cervical cancer. Methods:Immunohistochemical method was applied to examine the expression of survivin and VEGF in 20 normal and 46 cervical cancer tissues.Results:Survivin was detected in 29 of 46(63.04%) cervical cancer tissues,but 10% in normal cervix tissues; the expression of survivin in the two groups was significantly different(χ2=15.75,P
生存素是目前發現的最強的凋亡抑制因子,它是一種結構獨特的凋亡蛋白抑制因子(inhibitor of apoptosis protein,IAP),與細胞分裂、增殖有關,在胚胎組織和惡性腫瘤中表達,且與腫瘤細胞的分化增殖及浸潤轉移密切相關,正常成熟分化組織一般不表達或者弱表達。宮頸癌(cervical cancer)是最常見的婦科惡性腫瘤,但其病因及發病機制尚未完全清楚。本研究采用免疫組織化學技術檢測宮頸癌組織的生存素的表達情況,以探討其對宮頸癌的發生的可能作用。

[ABSTRACT]ObjectiveTo study the effect of CD59 gene on apoptosis of HeLa cell induced by HeNe Laser. MethodsHeLa cells were injected subcutaneously into the back of the mice in groupⅠ, and HeLa cells transfected with CD59gene into the back of the mice in group Ⅱ. After 24 h of the injection, the mice received HeNe laser radiation. Expressions of Fas, bcl2 and NFκB in tumor tissue were demonstrated via immunohistochemistry technique. ResultsCompared with group Ⅱ, tumor weight and the expressions of bcl2 and NFκB in groupⅠwere significantly lower (t=9.169;Z=-2.328,-2.367;P<0.05), while difference in the Fas expression between the two groups was not significant (Z=-0.643, P>0.05).ConclusionCD59 gene may promote the expressions of bcl2 and NFκB, suggesting its antiapoptosis effect.

【Abstract】 Objective
To investigate misdiagnosis reasons of the cutaneous m alignant melanoma.Methods One case of cutaneous m alignant melanoma misdiagnosed as dermatofibrosarcoma protuberans sarcoma were retrospectively analyzed. Results The left lower extremity skin tumor histology to the main spindle cells, arranged like spokes were no obvious pigmentation, sarcoma and dermatofibrosarcoma protuberans were very similar, but the results of immunohistochemical staining: the tumor cells S 00, HMB45 and MelanA positive diagnosis of cutaneous m alignant melanoma. Conclusion The clinical manifestations of m alignant melanoma of the complex, the lack of specificity, histological features varied, complex patterns, diagnosis should learn more about history, careful observation of slices, to be supplemented by checks to reduce misdiagnosis.省略
Expression of survivin in human colon carcinoma and its clinical significance
【Abstract】 AIM: To investigate the expression of survivin and its relationship with the clinical feature of colon carcinoma. METHODS: In 46 specimens of colon carcinoma and adjacent noncancerous colon tissues, the expression of survivin was detected by immunohistochemistry. RESULTS: Of the 46 cases of colon carcinoma, 28 cases expressed survivin but survivin was not detected in adjacent noncancer ous colon tissues. The expression of survivin in colon carcinoma was not associated with the patients age, gender and differentiated level (P>0.05), but with the metastasis of colon carcinoma (P

Abstract: Objective To discuss the pathology features, pathology diagnose as well as the differential diagnosis of the testicular diffuse large B-cell lymphoma. Methods Testicular diffuse large B-cell lymphoma is investigated by pathology and immunohistochemistry. Results In this case, the testicular diffuse large B-cell lymphoma is composed of medium or large lymphocytes. Immunohistochemistolly, tumor cells LCA and CD20 in these tumors all exhibited positive, while CD3,CD30,CD117 and CK proved negative. Conclusions The peripheral activation B-cell is the source of most of the testicular diffuse large B-cell lymphoma .Pathology biopsy and immunohistochemistry are very important for tumor diagnosis and differential diagnosis.
