摘要

目的:研究髋部骨折患者血清α-生育酚水平与术后机能恢复情况的关系。方法:选择2014年1月至2016年12月于兴宁市人民医院收治并获得1年随访的60岁以上老年髋部骨折手术治疗患者131例。使用高效液相色谱方法测定血清α-生育酚水平。使用下肢功能恢复量表(lower extremity gain scale,LEGS)、6 min步行测试(six-minute walk distance,6MWD)、SF-36简表躯体功能部分(short form-36 physical functioning domain,SFPF)评估骨折术后机能。结果:患者骨折术后基线血清α-生育酚水平为(42.1±10.0) μmol/L,随访1年后升至(51.3±13.8) μmol/L。按照基线血清α-生育酚水平三分位分组分析,最高分位α-生育酚患者术后2,6个月随访时LEGS及SFPF评分均显著高于另两个分位患者。在术后12个月随访中,最高分位α-生育酚患者LEGS (T3 32.7±7.9,T2 25.2±6.5,T1 21.5±6.8,P<0.001)、6MWD (T3 219.6±68.2,T2 202.3±82.7,T1 177.4±73.4,P=0.034)及SFPF(T3 60.0±21.9,T2 51.3±18.7,T1 35.3±14.3,P<0.001)均显著高于另两个分位患者。基线α-生育酚与患者术后随访1年LEGS,6MWD及SFPF均呈正相关,经多因素回归仍存在相关性。α-生育酚变化量仅与术后1年SFPF呈正相关。结论:血清α-生育酚水平与髋关节骨折术后患者身体机能密切相关,高基线α-生育酚水平的患者术后机能恢复较好。

Abstract

Objective: To investigate the correlation between serum α-tocopherol levels and the recovery of physical function after hip fracture. Methods: One hundred and thirty-one patients over 60 years old who received hip fracture surgery at Xingning People’s Hospital from January 2014 to December 2016 and had 1-year follow-up were retrospectively collected. Serum α-tocopherol were measured by high-pressure liquid chromatography. The physical function after hip fracture surgery was assessed by lower extremity gain scale (LEGS), six-minute walk distance (6MWD) and short form-36 physical functioning domain (SFPF). Results: The average level of α-tocopherol was (42.1±10.0) μmol/L, which rised to (51.3±13.8) μmol/L after 1-year follow-up. Furthermore, patients were grouped according to tertiles of baseline serum α-tocopherol levels. Patients in the highest tertile had higher scores of LEGS and SFPF at 2- and 6-month post-operative follow-up and higher scores of LEGS (T3 32.7±7.9, T2 25.2±6.5, T1 21.5±6.8, P<0.001), 6MWD (T3 219.6±68.2, T2 202.3±82.7, T1 177.4±73.4, P=0.034) and SFPF (T3 60.0±21.9, T2 51.3±18.7, T1 35.3±14.3, P<0.001) at 12 months when compared with the other two tertiles. Baseline α-tocopherol levels had positive correlation with LEGS, 6MWD and SFPF after 1-year follow-up, which still existed after multi-variate regression analysis. Also, the change of α-tocopherol levels was positively correlated with SFPF after 1-year follow-up. Conclusion: Serum α-tocopherol levels were closely related to the recovery of physical function after hip fracture. Patients with higher baseline levels of α-tocopherol had better recovery of physical function.
