Case-control study on transverse carpal ligament resection for the prevention of delayed carpal tunnel syndrome after distal radius fracture / 中国骨伤

<p><b>OBJECTIVE</b>To investigate the effects of open reduction by palm side for the distal radius fracture and T shape plate internal fixation with simultaneous anterior transverse carpal ligament resection for the prevention of delayed carpal tunnel syndrome after operation.</p><p><b>METHODS</b>From March 2000 to March 2007, 32 patients (8 males and 24 females, ranging in age from 46 to 66 years) with distal radius fracture were treated with open reduction by palm side and T shape plate internal fixation with simultaneous anterior transverse carpal ligament resection; while 30 patients (7 males and 23 females,ranging in age from 45 to 65 years) only with open reduction by palm side and T shape plate internal fixation. The incidences of delayed carpal tunnel syndrome between the two groups were compared.</p><p><b>RESULTS</b>Among 32 patients treated with open reduction by palm side and T shape plate internal fixation with anterior transverse carpal ligament resection, 3 patients had delayed carpal tunnel syndrome; while in 30 patients treated with open reduction by palm side and T shape plate internal fixation, 10 patients had delayed carpal tunnel syndrome. There was significant statistically difference (P < 0.05%).</p><p><b>CONCLUSION</b>Simultaneous anterior transverse carpal ligament resection can effectively prevent the delayed carpal tunnel syndrome occurrence for the distal radius fracture with open reduction by palm side.</p>

Study for phagaquosonogram acquisition module based on DSP / 中国医疗器械杂志

In this paper, a phagaquosonogram acquisition, a module with TMS320C6713 as a core, and USB as communicating pattern is introduced based on VC++6.0. The structure of the module, hardware configuration, software design and the experiment of the real phagaquosonogram signal collection are presented. It is shown that the module can extract human phagaquosonogram signal reliably and availably.

Experiences of cardiopulmonary bypass for heart transplantation / 中国医学科学院学报

<p><b>OBJECTIVE</b>To summarize the experiences of cardiopulmonary bypass (CPB) techniques in 15 patients of orthotopic heart transplantation.</p><p><b>METHODS</b>All patients received mild hypothermia and high flow rate perfusion. Effective strategies were taken to protect myocardium, lung, kidney, and blood conservation. The donor hearts were arrested with aorto perfusion using 1 000 ml St. Thomas solution at 4 degrees C, perfused with 1 000 ml University of Wiscosin (UW) solution or Histidin-Tryptophan-Ketoglutarat (HTK) solution at 4 degrees C, and then preserved in ice saline. Ice mud was covered on the donor heart during anastomosis. Low potassium cardioplegia solution was perfused before the unclamping of aorta.</p><p><b>RESULTS</b>The CPB time was (165.2 +/- 22. 8) min, the warm ischemia time was ( 7. 7 +/- 1. 7) min, and the cold ischemia time was ( 142. 4 +/- 11. 5) min. Heart beats was automatically recovered in 10 patients, and was recovered upon defibrillation in 5 patients. Left ventricular ejection fractions were (64. 1 +/- 4. 6) % after one month. All patients survived.</p><p><b>CONCLUSION</b>Proper CPB management and effective donor heart protection are essential to guarantee the success of heart transplantation.</p>

Two cases of extracorporeal membrane oxygenation as a bridge to heart transplantation / 中华器官移植杂志

160 s and core temperature was 36-37℃.Blood ga- ses,platelets,plasma free hemoglobin and coagulation factors were measured during ECMO support. The blood supply was monitored in the limbs cannulated with the femoral artery cannula.Results Two patients were successfully treated with ECMO without major complications.The circulatory and respiratory function of the patients was stable.The chest X-ray showed a no clouding of lungs and he- patic function was greatly improved in case 2 who underwent a successful heart transplantation follo- wing mechanical cardiocirculatory support as a bridge,Two patients received ECMO support for 5 and 3 days respectively.Both patients recovered well.No any severe acute rejection occurred and heart func- tion was NYHAⅠ.Conclusion When candidates suffered acute cardiogenic shock,ECMO can provide safe and effective mechanical circulatory support as a bridge to heart transplantation.
