RESUMO
Desmoglein,which is a kind of Ca2+ dependent desmosomal cadherins protein,is a major part of the desmosomes.The desmoglein that distributes in the epithelium,myocardium and other tissues plays a very important role in the cell junction.In recent years,the detection of the abnormal expression and function of the desmoglein was proved in many diseases,such as skin,mucous membrane and tumor related diseases.Drugs may have an important effect in the treatment of diseases by interfering with the expression and function of desmoglein.In this paper,the distribution of several subtypes of the family of desmosomes and their functions in the related diseases are reviewed,which may also provide some new clues for the new drug research on the target of desmogleins.
RESUMO
Objective At present,the detection rate of cervical metastatic lymph nodes in patients with papillary thyroid carcinoma (PTC) is relatively low by imaging technology.The article aimed to demonstrate the ultrasonographic features of PTC in predicting cervical lymph nodes metastasis(CLNM).Methods A retrospective analysis was done on 169 PTC patients proved by surgery and pathology who underwent cervical lymph node dissection in the Department of Ultrasonography in Nanjing General Hospital of Nanjing Military Command from January 2016 to March 2017.The patients were divided into CLNM group(n=83) and non-CLNM group (n =86).Analysis was made on the related risk factors of PTC CLNM.Results Multivariate logistic regression analysis showed that age(OR=0.211,95％CI:0.078～0.571,P=0.002),nodule size (OR=3.116,95％CI:1.498～6.482,P=0.002) and shape (OR=3.000,95％CI:1.301～6.913,P=0.010) were risk factors for CLNM in PTC(P＜0.05).The sensitivity rates of patient's age,nodule shape,module size,and microcalcification for predicting CLNM in PTC patients were 91％、79％、61％、75％ respectively.Conclusion For PTC patients less than 30 years old,ultrasonographic features with maximal diameter of nodule ＞ 1 cm,irregular shape,and microcalcification have a certain predictive value on CLNM and can be used as the basis for the selection of intraoperative cervical lymph node dissection.
