Diaper dermatitis is an infant dermatosis associated with the wearing of diapers, Despite of its high frequency in clinical pediatrics the clinical characteristics are not well described in the korean literatvre. We investigated the clinical and mycological characteritics of diaper dermatitis in 50 serial patients. Clinically diaper dermatitis was classified. into five categories,irritant contact derniatitis(ID), candidiasis(CD). combined rash of ID and CD(CR.), intertrigo, and miliari. Of 50 patients with diaper dermatitis, 18 had ID; 16, CI3; 10, CR; 5, intertrigo, and 1, miliaria, The mean age of patients with ID (11.8 months) was higher than that of patients with CD (4.0 months). Candida albicans(C. albicans) w is isolated from 25 patients with diaper dermatitis. The rate of positive cultures by clinical diagnosis was 130% in CD, 11.1% in ID, 60, 0% in CR, and 20.0% in intertrigo. C. albicons was isolated from 23 patients(82.1%) of patients with clinically suspected Ci") and 2 of 22 patients without the characteristic erythematous papulesThe presence of eryhematous papules was the most characteristic clinical feature of infection, Other candida species isolated from cut,aneous lesions were C. tropicalsis, C.'. parapsiolosis, and C. stellatoidea.

AIM:To determine the effect of rhBMP2 on the migration of human breast cancer cells MCF-7. METHODS:MCF-7 was induced by rhBMP2 (30 ?g/L) for 24 h. Atomic force microscopy (AFM) was used to observe the changes in cell morphology. Cell migration and invasion abilities were assayed by scratch healing and transwell experiments. RESULTS:The formation of lamellipodia and cell polarity together with increased cell length were observed in the cells treated with rhBMP2,whereas lamellipodia of cells in control group were not obvious and the majority of cells tended to be rounder with shorter cell diameter. Compared to control group,scratch healing and transwell experiments showed that the migration and invasion capacity of rhBMP2-induced MCF-7 cells was markedly enhanced. CONCLUSION:rhBMP2 induces human breast cancer cell MCF-7 to present the phenotype of migration and enhances the invasion capacity.

BACKGROUND:Cerebral aneurysm is a kind of mortal hemangioma, and its treatments such as endovascular embolization and clipping both cause high postoperative recurrence rate and mortality. So the stent implantation for cerebral aneurysm is coming into being. OBJECTTVE:To evaluate the hemodynamic parameters after stent implantation into cerebral aneurysm and to provide a novel feasible strategy for clinical treatment. METHODS:A retrospective analysis was preformed based on the CT image data of 11 patients with cerebral aneurysm from the Affiliated Hospital of Xinjiang Medical University. Firstly, the flexible and solid model of cerebral aneurysm was established by the MIMICS and reverse engineering. Secondly, the matching stent model was implanted into the cerebral aneurysm, and then the blood flow structure of cerebral aneurysm was analyzed by the fluid dynamics theory and the Fluent with the method of two-way flow solid coupling. Final y, comparative analysis of the kinetic parameters of cerebral aneurysm before and after implantation, including wal pressure, blood velocity, path line of the blood flow, wal shear stress, wal deformation was conducted, and blood flow characteristics after stent implantation were analyzed under different entrance velocity. RESULTS AND CONCLUSION:After implantation, the wal surface pressure was reduced about 61.1%;the blood flow velocity around the stent and the inside of the cerebral aneurysm was decelerated obviously;under setting 2 000 lines of blood flow, the number of path line of blood flow into the cerebral aneurysm reduced about 75.0%, the maximum wal shear stress decreased about 79.3%, and the maximum wal deformation reduced to a lower level. The entrance velocity was respectively v1=0.1 m/s, v2=0.2 m/s, v3=0.3 m/s and the wal pressure was in a gradient ascent;the wal shear stress increased with the velocity, meanwhile,τzou (left neck of aneurysm)<τzhong (aneurysm )<τyou (right neck of aneurysm). The path lines of blood flow mainly concentrated in the top of the aneurysm, and the blood velocity markedly affected the surface deformation. These results indicate that main hemodynamic parameters are obviously improved after stent implantation into cerebral aneurysm, and the blood velocity should never be neglectful in the treatment process.
