OBJECTIVEThe glucocorticoid dexamethasone (DEX) can induce palatal cleft; however, the mechanism involved remains unclear. E-cadherin is an important cell adhesion molecule, and it can significantly affect cell fate and embryonic development. Recent studies have indicated that E-cadherin expression in palatal epithelial cells is suppressed in normal palate fusion. This study aimed to determine whether the change in E-cadherin expression is related to the incidence of cleft palate in DEX-induced mice.
METHODSMice were divided into the experimental group and the control group. Pregnant mice were injected with DEX on E10.0-E12.0, whereas mice in the control group were injected with normal saline. Hematoxylin and eosin (HE) staining, immunohistochemistry, and real-time quantitative polymerase chain reaction were employed to evaluate the effect of DEX on fetal mouse palatal processes, particularly the changes in E-cadherin and β-catenin expression levels in the phases of the experimental and control groups.
RESULTSData indicated that the incidence of cleft palate in the DEX group was 43.59% (17/39), whereas that in the control group was only 3.03% (1/33). The results of HE staining showed that the obviously shortened palatal processes could not contact and fuse with one another in the DEX-treated mice model compared with those in the control group. The ectopic expression of E-cadherin in embryonic palatal mesenchymal cells was also analyzed. The expression levels of E-cadherin and β-catenin in the experimental group were higher than those in the control group.
CONCLUSIONThese findings indicated that DEX could induce E-cadherin gene upregulation and ectopic expression, as well as high β-catenin expression, thereby inhibiting the growth of mesenchyme cells and cleft palate.

OBJECTIVE:
To analyze the clinical features & variation features of cervical tuberculous lymphadenitis and to discuss its effective surgical treatment.
METHOD:
Retrospective analysis of 27 cases of cervical tuberculous lymphadenitis patients admitted to the hospital from January 2008 to December 2013. The cervical tuberculous lymphadenitis is classified based on the enhanced CT scanning conducted before operation and the preoperative evaluation of clinical characters of patients. The lymphaden ncisional biopsy was conducted on the type I patients with cervical tuberculous lymphadenitis. The lesion resection was performed on the type II and mixed type I + II patients. The regional cervical lymph node dissection was carried on the type III, the type IV and other mixed type patients. The negative pressure drainage ball was placed after operation, and the cavity was flushed with 5% povidone iodine solution. The antituberculosis therapy was performed after wound healing.
RESULT:
The analysis of the clinical features for 27 patients: the incidence rate on the left side, right side, both sides and middle-line is 63.0%, 25.9%, 7.4% and 3.7% respectively. The majority of patients whose lesion involving more than one region account for 62.1%; the patients whose lesion involving one region account for 37.9%. The most common is level V involved lesion (69.0%), then level IV (62.1%), level III (51.7%), level II (34.5%), level I (10.3%) and level VI (3.4%) in order. The analysis of the CT imageology features for 27 patients: the simple type is the majority (65.5%), and the most common is type III (24.1%), then the type I (17.2%), type II (13.8%) and type IV (10.3%) in order. The mixed type is minority (34.5%), but the two mixed is often (31.0%). The three mixed is only located on one side (3.4%). The recurrence never happened on the patients with resection and standard antituberculosis therapy.
CONCLUSION
For the cervical tuberculous lymphadenitis, the suitable surgical treatments shall be selected according to the lesion characteristics & location and CT imaging manifestations presurgical evaluation. The effective way to treat cervical tuberculous lymphadenitis is to conduct negative pressure drainage after operation, to flush the cavity with 5% povidone iodine solution and to perform antituberculosis therapy.
