[Objective]To analyze the clinical and pathological characteristics of myoepithelial carcinoma of nasopharynx,as well as its relationship with Epstein-Barr virus.[Methods]We report twelve cases of myoepithelial carcinoma of nasopharynx,study its clinical,histopathologic,and immunohistologic features,follow-up data and EBERS in-situ hybridization.[Results]Among age of patients ranged from 24 to 65 years(mean age=46 years).Imagery data demonstrated an extensive nodosity filling the nasopharynx,Of these 12 cgses,myoepithelial markers such as S-100,SMA,P63,CK14,CK5/6 and epithelial markers such as CK,CKL,CKH were not always all expressed at one case,but at less one of these two kind of markers expressed at one cage.The results of EBERS in-situ hybridization of 12 cases were negative.[Conclusion]Myoepithelial carcinoma is a low malignat tumor.It seldom takes place in nasopharynx,dispite its morphologic heterogeneity it has some special morphologic and immuohistologic characteristics as well as special result of EBERS in-situ hybridization,which may support its diagnosis.The combinde radiotherapy and chemotherapy after surgical removal of the tumor will control the recurrence and metabasis effectively.

Purpose To investigate the pathological characteristics of loco-regional recurrent nasopharyngeal carcinoma ( rNPC ) . Methods Nasopharyngeal biopsy specimens of 46 rNPCs and 63 primary NPCs were collected. HE staining, immunohistochemistry and EBV small RNAs ( EBERs) in-situ hybridization were performed. Results The over-expression rates of both p63 and CK5/6 in rNPC were significantly higher than those of primary NPCs (P=0. 005, P=0. 026), while no statistical significance of Ki-67 over-ex-pression existed between the two groups ( P=0. 387 ) . More necrotic tissues, inflammatory exudates, giant bizarre carcinoma cells, desmoplastic stroma, giant bizarre tumor cells and higher degree of squamous differentiation were found in rNPCs. The carcinoma cells of 5 rNPCs were negative for both EBERs in-situ hybridization and LMP-1 immunohistochemical staining. Conclusion The loco-re-gional rNPC has two peaks of latency interval:2~5 and 9~11 years. The loco-regional rNPC cells have higher degree of squamous differentiation with higher expression of p63 and CK5/6, as well as more invasive ability. In addition, both EBERs in-situ hybridization and LMP-1 immunostaining are negative in 10. 87% (5/46) of loco-regional rNPC.

Objective To investigate the way of pacemaker implantation in 127 elderly patients over 80 years old to reduce postoperative complications and improve the life quality. Methods One hundred and twenty-seven patients over 80 years old had the dual chamber pacing in 95 cases(74. 8%, including tri-chamber pacing) and the single ventricular pacing in 32 cases (25. 2%). Cephalic veins were used primarily in all patients with modified methods. The safe fixation of pacing leads were emphasized not only in the heart but also in the site of pacemaker pocket. The pacemaker package was made prior to the leads insertion in order to have enough time for stopping bleeding. It was necessary for some cases with diffused bleeding to use electric coagulation. All patients were told to get out of bed in the operating day or the day after procedure. Results Cephalic vein was well exposed. The successful rates of implanting pacing leads directly through cephalic vein were 92. 0% and 81. 5% in the single chamber and dual chamber patients, respectively. The overall complications observed in 5 cases(3. 9%) were pocket hematoma formation in 3 cases (2. 4%), cardiac tamponade in 1 case (0.8%), and disconnection of pacemaker with lead in 1 case (0.8%). There were no hemothorax, infection and lead dislodgement. Conclusions Insertion of pacing lead through cephalic vein is important, especially for the advanced aged patients. This operation can decrease the complications of subclavian vein puncture. Leads dislodgement are mainly due to the inadequate skill of operator, not to the patient s early activity out of bed. Appropriate way for stopping bleeding is the key to protect the patients from pacemaker pocket effusion and hemotama.

Objective To observe the biocompatibility of rabbit bone marrow mesenchymal stem cells (BMSCs)combined with allogeneic decalcified bone matrix(DBM)after transfecting adenoviral recombinant human bone morphogenetic protein-2(Ad-rhBMP-2).Methods The rabbit allogeneic DBM material was prepared according to the Ursit method.After transfecting Ad-BMP-2 on rabbit bone marrow mesenchymal stem cells,the immunohistochemical was used to detect the expression of BMP-2 in the transfected cells;after 48 h of transfection,the cells were planted on the allograft DBM,then the scanning electron microscopy was used to observe the cell growth and adhesion condition on material,and the proliferation condition of BMSCs was detected by MTT. Results After 48 h of adenoviral transfection,BMSCs could express BMP-2 successfully.The scanning electron microscopy showed that the cells after transfection adhered well and massively proliferated on DBM material.The MTT assay showed that the prolifer-ation condition of the cells after transfection planted on DBM was normal,which showed no statistically significant difference when compared with the control group (P >0.05).Conclusion The Ad-BMP-2 transfection on BMSCs is well biocompatible to allogene-ic DBM.

BACKGROUND:The complex relationship between bone marrow mesenchymal stem cels and cancers severely limit the clinical application of mesenchymal stem cels. So it is urgent to study the role of mesenchymal stem cels in tumor growth and metastasis.
OBJECTIVE:To explore the effect of human bone marrow mesenchymal stem cels on epithelial mesenchymal transition in non-smal cel lung cancer A549 and PAa cels.
METHODS:The A549 and PAa cels were cultured with mesenchymal stem cel supernatant (mesenchymal stem cel conditioned medium, MSCs-CM). The celular morphology was observed under a microscope. The mRNA and protein expression of E-cadherin, N-cadherin, Vimentin, Slug, Snail, and Twist were determined by RT-PCR and western blot. Transwel and wound healing assay were used to detect the change of migration and metastatic ability.
RESULTS AND CONCLUSION:Compared with the control group, the celular morphology of experimental group showed mesenchymal-like changes. In response to MSCs-CM, there was decreased E-cadherin but increased N-cadherin, Vimentin and Slug, Snail, Twist at mRNA and protein levels compared with the control group (P < 0.05). The migration and metastatic abilities of the experimental group were also increased. So, human bone marrow mesenchymal stem cels can promote epithelial mesenchymal transition in A549 and PAa cels, and enhance the migration and metastatic abilities of A549 and PAa cels.
