中药膳食配合运动干预对肥胖性脂肪肝的影响

目的 探讨中药膳食配合运动干预对肥胖性脂肪肝的影响。方法 将68例脂肪肝患者随机分为对照组和观察组各34例。对照组常规给予低脂饮食和易善复、大黄庶虫丸等降酶保肝治疗；观察组按常规方法治疗外，采用中医辨证施食予以活血化淤、健脾利湿的中药膳食疗法配合运动干预．疗程均为1年。结果 治疗后观察组体重、甘油三酯、总胆固醇、谷丙转氨酶等显著低于对照组（均P〈0．01）。结论 中药膳食配合运动干预对肥胖性脂肪肝疗效显著。     

Pediatric valve replacement, 15 years experience in Oman

Background Despite improving surgical techniques, treatment of heart valve disease in children remains controversial. Somatic growth and adequate anticoagulation are of concern when children undergo valve replacement. We conducted this study to evaluate the performance of valves in this age group. Methods 42 children under the age of 13 years who underwent valve replacement were included in this study. Totally, 50 valves were implanted in 42 patients: 48 were mechanical prostheses, two were bioprosthetic both in pulmonary position. 37 (74%) valves were implanted in mitral position, 10 (20%) in aortic position, 1 (2%) in tricuspid position and 2 (4%) in pulmonary position. Preoperatively, 14 (33,3%) patients were in New York Heart Association (NYHA) class IV, while 27 (64.2%) were in NYHA class III. Results There were 2 (4.7%) hospital deaths and 2 (4.7%) late deaths while 2 (4.7%) patients were lost to follow up. The mean follow up period was 9.4 yrs. 35 (83.3%) patients are in NYHA Class I and free of all medications except warfarin. 3 (7.1%) patients have undergone 5 successful pregnancies. The median INR was 2.23. Major thrombo-embolic episode occurred in 1 (2.3%) patient. Conclusions In view of the problems of sizing, anticoagulation and need for re-operation at an early age, there is a reluctance to replace valves in children. This study shows that despite these problems, valve replacement can be undertaken safely and successfully in children, when repair has failed or not technically feasible.
