目的 观察三种不同血液净化方式[血液透析（HD）、血液透析滤过（HDF）、血液透析+血液灌流（HD+HP）]对维持性血液透析患者高磷血症清除效果。 方法 选择2009年2月－2011年2月行维持性血液透析的48例高磷血症患者为研究对象，所有患者在低钙透析（1.25 mmol/L）的基础，随机分为HD组、HDF组、HD+HP组，每组16例，分别在治疗时及治疗后4周、8周检查钙、磷、钙磷乘积和全段甲状旁腺激素，并观察其变化。 结果 在治疗4周、8周后，HDF组、HD+HP组磷较前均显著下降（P值均＜0.05），两组同时点相比较差异无统计学意义（P＞0.05）；HD组较前血磷无明显变化（P＞0.05）。 结论 HDF、HP清除维持性血液透析患者高磷有显著的效果，而HD效果则不佳。
【摘要】 目的 探讨切开复位肱骨近端内固定锁定系统(proximal humeral internal locking system，PHILOS)治疗老年肱骨近端骨折的疗效。 方法 2008年5月-2009年5月，对22例60岁以上肱骨近端新鲜移位骨折按Neer分型，二部分2例，三部分16例，四部分4例；采用肩前方入路切开复位PHILOS治疗。 结果 22例患者获12～18个月随访，平均14.6个月，采用Constant-Murley评分，优8例，良10例，可3例，差1例，优良率81.4%。 结论 切开复位PHILOS治疗老年肱骨近端骨折疗效肯定。【Abstract】 Objective To discuss the clinical effect of open reduction and internal fixation with the proximal humeral internal locking system (PHILOS) plate in treating elder patients with proximal humeral fracture. Methods From May 2008 to May 2009, we classified 22 cases of fresh displaced proximal humeral fracture according to the Neer classification. All patients were older than 60 years. There were two cases of two-part fracture, 16 cases of three-part fracture and four cases of four-part fracture. The open reduction and internal fixation with PHILOS plate was performed with the anterior deltopectoral approach. Results The 22 patients were followed up for 12 to 18 months with a mean period of 14.6 months. According to Constant-Murley Shoulder Score measurement, eight cases were graded as excellent, 10 good, three fair, and one poor with a excellent and good rate of 81.4%. Conclusion The open reduction and internal fixation with Philos plate is effective in treating elder patients with proximal humeral fracture.
