Objective] To investigate the effects of a short -term very low carbohydrate diet (VLCD) intervention on bone turnover of overweight and obese subjects .[Method] A total of 205 overweight or obese subjects were recruited and random-ized into control group and treatmeat groupwith a ratio of 1:3 .The control group received medical lifestyle intervention ,while the intervention group received very low carbohydrate diet intervention in addition to medical lifestyle intervention .Body weight , waist circumstance ,BMI ,Parathyroid hormone(PTH) ,β-crosslaps(β-CTx) ,N-terminal osteocalcin (TNOC) ,total pro-collagen I type N-terminal propeptide (P1NP ) and 25-OH-D3of each subjectwere measuredbefore and after the interven-tion .[Result] The body weight ,BMI and waist circumstancewere significantly decreased in the both groups ,butshowed more significantdecreasein the VLCD intervention group ( P< 0.01 ) .There were no significant difference in bone turnover between the two groups after intervention (P>0.05) .[Conclusion]Short-term very low carbohydrate diet intervention can improve body weight ,BMI and waist circumstance in overweight or obese subjects while has no significant impact on bone turnover .

随着透析技术的进步和透析质量的提高,透析人群中老年患者比例大量增加.高龄患者多伴有心血管并发症.透析治疗中常因低血压诱发心律失常,甚至循环衰竭,严重危害健康及生命[1],因此及时有效地预防透析过程中的低血压尤为重要.本文通过对26例老年透析病人(共1616次透析)按不同时间采取不同的干预方法比较其低血压发生率,发现低温可调钠透析结合参附制剂可有效预防高龄患者低血压的发生.现报告如下:

随着我国正步入老龄化社会,进行血液透析的高龄患者也日益增多.高龄透析患者往往在透析前已存在营养不良,进行透析后,如营养管理不善,营养不良则更为明显.本科2007年6至12月对26例维持性血液透析高龄患者进行6个月的营养不良干预,取得了较好效果.报告如下.

老年人进行维持性血液透析时所建自体动静脉内瘘的成功率较低,且容易发生各种并发症,因此,各项护理措施十分重要.现将自体内瘘血管的老年维持性血液透析患者的护理体会介绍如下.

目的总结连续性静脉—静脉血液滤过(CVVH)抢救74例老年多器官功能障碍综合征(MODSE)的护理经验。方法对74例MODSE患者采用CVVH治疗,检测治疗前后pH值、血肌酐变化情况。结果74例MODSE病患者经综合抢救及连续性静脉—静脉血液滤过治疗后动脉血pH值、HCO3-较治疗前升高,BE和血肌酐较治疗前显著下降(P<0.05)。存活22人,总存活率为30%。结论CVVH能纠正MODSE患者内环境紊乱,改善预后,提高存活率。
