异倍体

The results showed that aneuploid rate was 84.6％ in all of these patients.

结果：52例滑膜肉瘤中44例为异倍体，异倍体检出率为84.6％。

Objective To evaluate the clinical significance of the detection of DNA aneuploid and telomerase activity in the diagnosis and differential diagnosis of malignant pleural effusion.

目的 了解不同类型胸腔积液表达DNA异倍体和端粒酶活性的差异，探讨DNA异倍体和TA诊断与鉴别诊断恶性胸腔积液的价值。

The tumors with double DNA heteroploidies (3cases) were much more malignant in nat- ure than those with diploidy + heteroploidy.

双异倍体干系肿瘤（3例）的性质极恶，2倍体加异倍体肿瘤的行为略好。

The rates of the heteroploidy and aneuploidy rose gradually in the shift of benign- borderline-malignancy, and the same was true for the rat es of mortality/relapse as well as the contrast risk. The nature of ovarian tumors with heteroploidy was much malignant than that with diploidy.

在良性、交界性至恶性肿瘤系列中，异倍体率或非整倍体率明显增加，病死和复发率及相对危险性随之增高；异倍体肿瘤的性质较恶，2倍体肿瘤趋于良性。

This study shows that the quantity DNA heteroploid in precancersis with larynx increases as high as the grade does,and DNA heteroploid may be one of the important markers of precancersis with larynx.

提示喉癌前病变的DNA异倍体率随不典型增生病变的分级增高而增加，不典型增生程度越高，癌变率越高，提示DNA异倍体可能是喉癌变早期的分子标志物。

The results showed that 69.0%of small HCC and 87.6%of large HCC had heteroploid DNA content. The difference of the rate of heteroploid between the large HCC and small HCC was statistically significant. However, no correlation was found between DNA content, pathologic staging and Vmax RI of the arterial blood flow.

结果表明：小肝癌异倍体发生率为69.0%，大肝癌异倍体发生率为 87.6%，两组间异倍体发生率有显著性差异，但内部及外周动脉血流的有无及其最大流速、阻力指数的高低与异倍体发生率、病理分级无显著相关。

If 〓mRNA positive expression, its DNA heteroploid type display as triploid or hypodiploidy, if 〓mRNA negative expression, its DNA heteroploid type display as hyperdiploidy、tetraploid or Bistem line. These from one flank demonstrate the role of 〓 gene suppress the proliferation of malignant tumor

表达阳性者，其DNA异倍体主要表现为三倍体或低二倍体，〓表达阴性者，其DNA异倍体主要表现为高倍体、四倍体和双干系，从一个侧面显示出〓基因的抑制恶性肿瘤细胞增殖的作用。

Results The p53 gene mutation rate of colorectal cancer was 50%. The rate of apoptosis of tumor cells having mutation of p53 gene (22.11%) was much lower than that having no p53 mutation (40.57%, P＜0.05). Heteroploid cells had been found in 10/13 tumor samples with p53 gene mutation and 6/13 samples without p53 mutation (P＜0.05). The rate of apoptosis had no difference between the heteroploid cases and diploid cases.

结果 大肠癌标本p53基因突变率为50%；其中突变组肿瘤细胞凋亡率(22.11%)明显低于未突变组细胞凋亡率(40.57%)，(P＜0.05)；突变组异倍体细胞百分率(占76.9%)明显高于未突变组(占46.2%)，(P＜0.05)；异倍体肿瘤细胞凋亡率为34.0%，二倍体肿瘤细胞凋亡率为40.7%，二者差异无显著性(P＞0.05)。

The 5-year overall survival rate was 65.61%. The 5-year overall, distant metastasis-free, and local progression-free survival rates were significantly higher in diploid group than in heteroploid group 80.92% vs.

全组5年总生存率65.61%，其中二倍体组为80.92%，异倍体组为42.86%(P=0.002)；5年无远处转移生存率二倍体组为84.26%，异倍体组为44.53%(P=0.003)；5年无复发生存率二倍体组为92.59%，异倍体组为72.65%(P=0.118)。

Results The deˉtection ratio of heteroploidy in leukemia children was more than that in non-leukemia.

结果 白血病组异倍体检出率明显高于非白血病组。12例非白血病中4例为异倍体，其中2例癌变。
