RESUMO
Objective To study the methods and clinical effects of joint expansion of double fascia flaps wrapping the Medpor to perform full-ear reconstruction on congenital microtia deformity.Methods 60 patients with congenital microtia deformity were selected.including 22 left ears and 38 right ears.Majority had loss of ear auricle or only partial earlobe.Phase Ⅰ procedures included:temporal-parietal branch was used for the vascular pedicle,and mastoid area behind the ear was moved and expanded for fascia flap.Phase Ⅱ included:the joint expansion of double fascia flap wrapped Medpor to do full-ear reconstruction.Results Flaps survived and no complications for all 60 patients.Reconstructed ears had lifelike appearance and clear anatomical structures.Auriculocephalic angulars positions and sizes were consistent with the healthy ears.None of them had exposed prosthesis and scar contraction.Three-dimensional shapes were good.Conclusions Joint expansion of double fascia flap wrapping Medpor could avoid the chest wall deformity and exposed prosthesis.The fine structure of the reconstructed ear is satisfactory.
RESUMO
Aim To explore the expression of TNF-related apoptosis-inducing ligand(TRAIL)between psoriatic patients and healthy subjects.Methods Immunohistochemical staining and Real-Time PCR methods were established to detect the expression of TRAIL.Results Immunohistochemical staining results indicated a significant difference of the expression of TRAIL between psoriatic patients and healthy subjects.Real-Time PCR results indicated that the quantities were 0.42?0.07,1.01?0.16 respectively of two type skins.Thus there were significant differences(P
RESUMO
Objective To find out current distribution of Oncomelania snails and Schistosoma infection in snails in Zhejiang Province, so as to improve the project of schistosomiasis control. Methods Investigation spots were selected by stratified cluster sampling method, 100 villages of 34 counties were selected from 7 106 villages of 55 counties as survey spots. Synchronously systematic and environmental samplings were used for the survey. Snails were dissected to determine the infection status and spots with sham snails were set to assess the quality of the survey. Results The result showed that snails were found in 223 strips, 1 572 frames and 73 300 m 2 area in 32 villages of 21 counties. Snails were found in an area covering 72 640 m 2 in 29 villages of 18 counties in hilly region, which accounted for 99.1% of total snail habitats. The significantly larger area with snails was revealed in hilly region than that in water network region (t=3.04, P
