RESUMO

Cervical cancer is one of the most common gynecological malignancies which seriously threatens the health of women. How to further expand the scope of screening and improve the sensitivity and specificity of screening and optimize screening programs are the key points of cancer prevention and treatment. At present,the screening methods that are commonly used at home and abroad include cervical smear cytology, human papillomavirus ( HPV) detection,molecular biology detection and genetic genetic testing. Cervical smear cytology has high specificity and low sensitivity,the sensitivity of HPV detection is high,but the specificity is low,and the molecular biological detection and genetic testing has high specificity and high sensitivity,but due to the lack of large quantities of clinical samples,and the higher detection cost,they are still in the test study stage.

RESUMO

Uterine junctional zone (JZ) was first described by Hricak et al in 1983,which is a low signal-intensity zone between myometrium and endometrium on T2-weighted MR images.Subsequent studies confirmed that JZ is located in the innermost layer of the myometrium.It has been confirmed that JZ dysfunction is strongly associated with uterine fibroids、adenomyosis、endometriosis,etc.In recent years,researchers have focused their attention on the ultrastructure of JZ,tring to find out the structural basis that caused the abnormality of JZ.This review focuses on the physiological characteristics and ultrastructure of normal and endometriosis disease uterus JZ.

RESUMO

The existence of stern/progenitor cells in the endometrium was postulated many years ago,but the first functional evidence was published in 2004.The study of endometrial stem/progenitor cells had opened up an active field in the subsequent 10 years.Human endometrium has immense regenerative capacity and bilayer structure,in which the upper functionalis is shed at menses and regenerates from the remaining basalis in the subsequent cycle,these characteristics had been the motivation for investigators to identify and characterize endometrial stem/progenitor cell populations.The discovery of specific markers for endometrial stem/progenitor cells has enabled the examination of their role in endometrial proliferative disorders,including endometriosis,adenomyosis and Asherman's syndrome.

RESUMO

The traditional view that vitamin D is mainly involved in bone metabolism and calcium and phosphorus homeostasis,and bone-related diseases such as osteoporosis related.However,some recent studies have shown that vitamin D plays a key role in obstetrics and gynecology diseases,particularly,endometriosis and ovarian cancer,preeclampsia and gestational diabetes mellitus (GDM) in polycystic ovary syndrome influence (PCOS).Advances in vitamin D article and on the relationship between gynecological and obstetrical diseases were reviewed.

RESUMO

Objective To evaluate the clinical value of three-dimensional power Doppler ultrasound (3D PDUS) in diagnosing cervical cancers.Methods 162 patients with cervical lesions were enrolled.All the cases were confirmed by autopsy or surgery.Vascularization index (VI),flow index (FI) and vascularization flow index(VFI) were all measured and compared.The pathological findings was taken as golden standard.ROC curve was used to find the best cut-off value.Results 3D PDUS indices of benign and malignant lesions were statistically different (P <0.0001).The best cut-off value of VI was 4.63 using ROC curves,the area under the curve (AUC) was 0.94,the sensitivity and specificity were 89.10% and 86.30%,respectively.The best cut-off value of FI was 34.39 using ROC curves,AUC was 0.76,the sensitivity and specificity were 73.40% and 76.70%,respectively.The best cut-off value of VFI was 1.60 using ROC curves,AUC was 0.93,the sensitivity and specificity were 87.50 % and 86.30 %,respectively.Conclusions 3D PDUS was a new and noninvasive way for the clinical to differentiate benign and malignant cervical lesions.
