Methods SP immunohistochemical staining was used to detect the level of VEGF and EG-VEGF in 85 cases of the epithelial ovarian tumor tissue(25 cases of benign tumor,27 cases of ovarian carcinoma of stage FIGOⅠ、Ⅱ,33 cases of ovarian carcinoma of stage FIGOⅢ、Ⅳ)and 20 cases of normal ovarian tissue.The integral optical density was measured.

方法应用免疫组织化学SP法和形态定量学方法检测85例卵巢上皮性肿瘤(良性25例，FIGOⅠ、Ⅱ期卵巢癌27例，FIGOⅢ、Ⅳ期卵巢癌33例)和20例正常卵巢(除外卵巢疾病的绝经前患者)组织中VEGF、EG-VEGF表达的阳性率及积分光密度值。

The CA125 is an epitope on a large mucin glycoprotein molecule of greater than 1 million Daltons,normal expressed on the coelomic epithelium,including ovarian surface.By now,CA125 assay has been used for monitoring response to primary treatment,detecting clinically occult ovarian cancer at the time of recurrence,as well detecting primary disease in early stage.The CA125 level is abnormal in over 90%of advanced stage ovarian cancer,but it is not increased in about 50%of the patients with stageⅠdisease.

卵巢癌肿瘤标记物中最常用的是CA125，它是体腔上皮正常表达的一种抗原蛋白，晚期卵巢癌中，超过90%病例CA125升高，而在Ⅰ期卵巢癌中，大约有50%病例CA125正常，因此血清CA125敏感性和特异性不能满足筛查指标的要求。

Down-regulated expression of PTEN and up-regulated expression of VEGF〓 were considered as two important events in tumorigenesis of ovarian cancer and could act as molecular markers to indicate the pathobiological behaviors of ovarian cancer. Decreased PTEN expression and increased VEGF〓 expression were closely associated with tumorigenesis and pathobiological behaviors of ovarian endometrioid and serous cancer respectively. Reduced expression of PTEN gene might be involved in carcinogenesis and progression of ovarian cancer by up-regulating the VEGF〓 expression to enhance angiogenesis.

在卵巢癌组织中PTEN基因mRNA表达下调和VEGF〓基因mRNA表达上调是卵巢癌发生的重要分子事件，可作为反映卵巢癌病理生物学行为的指标，且分别与卵巢内膜样癌和浆液性囊腺癌的发生和病理生物学行为关系密切；PTEN基因mRNA表达降低可能通过上调VEGF〓基因mRNA表达促进新生血管形成，进而参与卵巢癌的发生和侵袭。

Ovarian stromal flow PSV, EDV and perifollicular vascularity are highly interrelated with ovarian response. Ovarian response will be improved when ovarian blood velocity increases and perifollicual blood flow is abundant. Follicular fluid VEGF level was obviously higher in poor responder group, which suggests VEGF be secreted increasing for compensating due to reduced ovarian stromal blood velocity and fewer perifollicular vascularity.

卵巢基质内血流的PSV、EDV和卵泡周血流分布、卵泡液VEGF水平与卵巢的反应性密切相关，卵巢基质内血流速度升高、卵泡周边血流丰富，有助于提高卵巢的反应性；低反应卵巢组卵泡液VEGF水平显著升高，推测是由于其卵巢基质内血流速度低，卵泡周血管分布少，导致VEGF代偿性分泌增加。

K-means, and self-organizing map and the feature selection methods based on coefficient of variation and simple T-test were integrated. To evaluate the performance of the Samcluster system, the Samcluster was applied to four expression datasets COLON, LEUKEMIA72. LEUKEMIA38, and OVARIAN. The results show that there are only 5, 1,0, and 0 samples misclassified, respectively. We conclude that the proposed scheme. SamCluster. is an efficient method for automatic discovery of sample classes using gene expression profile.

在Samcluster系统中，整合了下列聚类算法：谱系聚类、K-平均值聚类和自组图聚类与变异系数计算和T-检验等基因变量选择方法，并提出了一致的样本分型概念，通过对四个基因表达谱的数据集COLON、LEUKEMIA72、LEUKEMIA38和OVARIAN的测试，结果表明：误判的样本数分别为5、1、0和0个，因此，基因水平的样本分型与样本的临床分型高度一致。
