Clinical Significance on the Expression of Estrogen and Progeste rone Receptors in Endometrial Carcinoma,Atypical Hyperplasia and Normal Endome trium / 医学研究杂志

The purpose of this article is to d iscuss the meaning and the method of testing the ER/PR.We use the anti-ER、 ant i-PR monoclonal antibody SP method to detect the ER/PR in 26 cases of the endome trial cancinoma endometrium、23 cases of the atypical hyperplasia and 22 cases o f the normal endometrium respectively.The result shows that the SP method to t est the ER/PR has different result in carcinoma、atypical hyperplasia and normal endometrium.The expression of ER/PR in carcinoma is distinctly lower than th at in the atypical hyperplasia and normal endometrium.There is no significant d ifferent between the atypical hyperplasia and normal endometrium of the expressi on of ER/PR.However,there are significant different in the ER.PR expressions b e tween normal endometrium and endometrial careinoma,and between atypical hyperpla sia and endometrial careinoma,reflecfing the special biological action of the tu mor.SP method to test the expression of ER/PR has some special meaning to estim ate the prognosis and supervises the treatment of the carcinoma of the uterine.

The Value of Transvaginal Color Doppler Ultrasonography (TVCDU) in the Diagnosis of the Gestational Choriocarcinoma / 实用放射学杂志

Objective To evaluate the clinical value of TVCDU in the diagnosis and followed-up of the gestational choriocarcinoma . Methods TVCDU and related clinical data of 21 patients suffered from the gestational choriocarcinoma during May 2003 and July 2004 were restrospectively analysed.Results The sonographic manifestations of choriocarcinoma could be classified into 5 types;(1)The uterine became larger than the normal , the local myometrium was changed into irregular non-echo region which was full of blood testified by CDFI(Color Doppler flow image);(2)The myometrium became nonhomogenity with plenty of blood flow , the resistance index ( RI ) was 0.25~0.47;(3)The abnormal echo emerged in the uterine cavity was not apparent boundary to the myometrium; (4)Neoplasm in the adnexa had relatively obvious blood flow,RI was about 0.4;(5)There was no abnormal echo in pelvic organ. The relation ship between sonographies and HCG first determined was complex. However,the lesions reduced, RI descended during the treatment of chemical therapy, so did the HCG .Conclusion TVCDU plays an important role in the differential diagnosis and the evaluation of curative effects of choriocarcinoma during the course of followed- up.

Three-dimensional ultrasound imaging in uterus / 中华超声影像学杂志

Objective　To study the value of three-dimensional ultrasound imaging (3DUS) in uterus.Methods　The transvaginal 3D images were reconstructed in 32 patients.Results　The rate of satisfactory imaging is 96.6%,the accuracy of diagnosing uterine anomalies and localizing uterus leison is 100% and 96.6%,respectively.Conclusions　3DUS is of great value in diagnosing uterine anomalies and localizing uterus lesion.

Study on nuchal skin thickness of normal fetal by ultrasonography / 中华超声影像学杂志

ObjectiveTo explore ultrasonographic featurs of nuchal skin of normal fetus in its thickness and changes.MethodsThe thickness of nuchal skin of 900 normal fetal was measured by abdominal ultrasound with 7.5 MHz probe.ResultsThe nuchal skin only displayed whole layer before pregnant 27 weeks. After pregnant 27 weeks, the derma and subderma layer was distinguishable, the whole thickness of nuchal skin was ( 1.18 ? 0.05 )mm (10 weeks) to ( 6.01 ? 0.46 )mm (40 weeks) in normal fetus. All layers of nuchal skin were increased proportionally with gestation [r= 0.973 (whole layer), P 0.05 ).Conclusions The abnomal chromosome of fetus could be sifted by the thickness of nuchal skin and the character of sonographic image. It′s a useful diagnostic method for eugenics.
