Objective To explore the feasibility of off-pump coronary artery bypass grafting (OPCAB) in the treatment of severe coronary atherosclerotic heart disease. Methods Clinical data of 37 cases of severe coronary heart disease from January to December, 2002, were retrospectively reviewed. All operations were conducted under general anesthesia by midline sternotomy. The left internal mammary artery (LIMA) and the great saphenous vein (SV) were divided for grafting. Then we stabilified the local myocardium and exposed the diseased coronary arteries. Following the insertion of an intracoronary shunt, the LIMA was anastomosed to the left anterior descending artery (LAD). Afterwards, the SV was proximally anastomosed to the aorta, and then, to the coronary artery. Results All the operations were completed by beating heart revascularization. The number of bypass grafting was 3 2?0 5 (range, 1～6). Except 1 patient died on the 10th postoperative day, no severe complications, such as peri-operative myocardial infarction, respiratory failure, renal insufficiency or cerebrovascular accident, took place in the remaining 36 patients. Conclusions In the context of skillful procedure techniques and strict peri-operative management, OPCAB in the treatment of severe coronary atherosclerotic heart disease is feasible.

Objective To develope both qualitative and quantitative analytic method of the four urinary markers,i.e.lactate,uracil,orotate and hippurate,from ornithine transcarbamylase deficiency(OTCD) by Gas Chromatography-Mass Spectrometry(GC-MS).Methods Urea in urine samples was decomposed with urease,and heptadecanoiate was added as internal standard,then protein was denatured with ethanol and removed by centrifugation.After evaporation,the residue was derivatized trimethylsilylly by BSTFA/TMCS,and analyzed by GC-MS.ResultsThe markers can be separated in total ion current profiles,with indentifications confirmed by mass spectra.The significantly elevated levels of lactate,uracil and orotate in urine from OTCD patient were droped to normal or subnormal levels,together with large amount of hippurate excretion in the urine,after clinical therapeutic measures,including introduction of benzoic acid,were performed.Conclusion GC-MS analysis of the urinary markers is a valuable tool for the diagnosis and evaluation of the therapeutic outcome of OTCD.

Objective This study was conducted to describe job stressors of nurses employed in military hospitals and relationship between job stressors and demography characters.Method 296 employed nurses were investigated by nurse job stressor questionnaires.Result Professional and career issues were the most frequently encountered job stressor among employed nurses,the other stressors in descending order were workload and time pressure,patient care and interaction,resource and environmental problems,management issues.Job stressors of nurses could be influenced by their age,job title,et al.Conclusion The finding suggest that effective stress management strategies should be relieve job stress.

AIM: To determine the contents of tetrandrine and fangchinoline in Qingshenjianfei Tablets by RP-HPLC. METHODS:In this method Zorbax C 18 column was used, and methanol—0.3%diethylamine (75∶25) as a mobile phase , the detection wavelength was at 242 nm. RESULTS:The recovery of tetrandrine was 103.65% and RSD was 1.59% .The recovery of fangchinoline was 97.11% and RSD was 1.91% (n=6). CONCLUSION: This method is simple,quick,reproducible and can be used for the quantitative analysis。
