The preoperative pelvic Doppler ultrasonography was done to determine the blood flow parameters resistance index (RI) and pulsatility index (PI) of the endometrial lesions;after surgical resection, the endometrial cancer lesion tissue was collected from the observation group and normal endometrial tissue was collected from the control group to determine the contents of pro-proliferation molecules, pro-invasion molecules and angiogenesis molecules.Results: PI and RI levels in endometrial cancer lesion of observation group were significantly lower than those of control group, and cIAP1, cIAP2, RLIP76, p-Pak4ser474, EFEMP2, CXCR4, CXCR7, Snail, Septin-9,β-arrestin2 and SOX2 protein levels in endometrial cancer lesion were significantly higher than those of control group;PI and RI levels in endometrial cancer lesion were negatively correlated with cIAP1, cIAP2, RLIP76, p-Pak4ser474, EFEMP2, CXCR4, CXCR7, Snail, Septin-9,β-arrestin2 and SOX2 protein levels.Conclusion: The Doppler ultrasound parameters of endometrial carcinoma lesion are closely related to the angiogenesis and cancer cell growth in the lesion.展开更多

Methods: A total of 118 patients who were examined and diagnosed with endometrial benign hyperplasia in the hospital between December 2012 and January 2017 were collected as endometrial hyperplasia group, and 67 patients with endometrial carcinoma were collected as endometrial cancer group. The differences in the levels of uterine contrast-enhanced ultrasound parameters as well as the expression of proliferation, apoptosis and invasion genes in endometrial lesion tissue were compared between the two groups. Pearson test was used to evaluate the correlation between uterine contrast-enhanced ultrasound parameters and malignant molecule expression in the lesions. Results: Contrast-enhanced ultrasound parameter TTP level of endometrial cancer group was lower than that of endometrial hyperplasia group whereas PI level was higher than that of endometrial hyperplasia group. Proliferation gene EFEMP2 mRNA expression in lesion tissue of endometrial cancer group was lower than that of endometrial hyperplasia group whereas RRM2 and DJ-1 mRNA expression were higher than those of endometrial hyperplasia group;apoptosis genes P53, c-myc and Livin mRNA expression were higher than those of endometrial hyperplasia group whereas Caspase-3 and Bid mRNA expression were lower than those of endometrial hyperplasia group;invasion gene DKK1 mRNA expression was lower than that of endometrial hyperplasia group whereas HMGB1, EZH2 and Snail mRNA expression were higher than those of endometrial hyperplasia group. Pearson test showed that the contrast-enhanced ultrasound parameter levels of endometrial cancer were directly correlated with the malignant molecule expression in the lesion tissues. Conclusion: contrast-enhanced ultrasound parameter levels can be used to identify endometrial benign and malignant lesions and are directly correlated with the severity of the lesion.展开更多
