Multi-points pulse information acquisition and 3-D reconstruction based on grid-net images / 中国医疗器械杂志

A method of acquiring radial pulse information from the grid-net area on every pulse image frame is proposed based on the principle of lens imaging and the characteristics of image data. The radial pulse image data are collected by the pulse image sensor. Multi-points out-of-plane displacements of the pulse are acquired by the method. And the membrane surfaces are reconstructed, then the 3D information of the pulse can be observable.

Video-assisted thoracoscopic esophagectomy in esophageal carcinoma / 中华胃肠外科杂志

<p><b>OBJECTIVE</b>To evaluate the efficacy and safety of video-assisted thoracoscopic (VATS) esophagectomy in the treatment of esophageal cancer.</p><p><b>METHODS</b>From June 2004 to October 2007, video-assisted thoracoscopic esophagectomy was performed in 36 patients, including 29 men and 7 women with median age of 58.9 years old. The cancer located at upper segment in 5 cases, middle 25 cases and lower 6 cases. VATS approach was used to mobilize the intrathoracic esophagus and stomach was mobilized by open approach. Esophagogastric anastomosis was performed in the left neck.</p><p><b>RESULTS</b>The mean operative time was 250 minutes (190-330 min) and average time of VATS was 70 minutes. The mean hospital stay was 8.7 days. Mean lymph node harvest was 14.3 nodes. Post-operative complications occurred in 11 patients(30.6%), but no perioperative death occurred.</p><p><b>CONCLUSION</b>Video-assisted thoracoscopic esophagectomy is technically feasible and safe with lower morbidity and shorter hospital stay as compared to open procedure, and may replace the open esophagectomy in selected patients.</p>

Protective effects of curcumin or dexamethasone on ischemia-reperfusion injury of rat lung grafts / 中华器官移植杂志

Objective To investigate the curative effects of curcumin(CUR)or dexamethasone (DXM)on ischemia-reperfusion injury(IRI)of rat lung grafts.Methods Male SD rats were randomly divided 4 groups:CUR group(CUR was administered intraperitoneally to both donors and recipients at 3 h prior to operation);DXM group(DXM was administered intraperitoneally at 30 min prior to operation);vehicle group(Animals were injected with the DMSO to both donors and recipients at 3 h prior to operation);sham group(Time-matched control animals underwent the same surgery,except that no graft was implanted).Six animals were sacrificed at different reperfusion periods of 2 h and 24 h,respectively.Oxygenation indexes(PO_2/FiO_2),lung injury scores,wet/dry ratio(W/D)and myeloperoxidase(MPO)activity in the transplanted lung were measured.Malondialdehyde(MDA), total anti-oxidative capacity(TAOC),tumor necrosis factor(TNF)-?and interleukin(IL)-6 in the transplanted lung and serum were determined.Results The levels of LPV PO_2/FiO_2 were significant- ly higher in the CUR and DXM groups than in the vehicle groups both 2 and 24 h after reperfusion,re- spectively(P
