摘要 目的 观察重组人促红细胞生成素(EPO)对大鼠股骨头坏死的预防作用.方法 将雄性SD大鼠60只随机分为3组,分别为空白组、对照组、实验组.将对照组再分为组A和组B:组A每周一、周五在大鼠臀肌处注射醋酸泼尼松龙50 mg/kg,1次/天,持续4周;组B在进行造模之前3h在大鼠臀肌处注射同EPO等体积的0.9%氯化钠注射液,其余处理措施同组A.实验组每次造模前3h在大鼠臀肌处注射EPO溶液,5000 IU/kg.结果 (1)骨陷窝率:苏木素-伊红(HE)染色切片显示实验组空骨陷窝率为(14.70±1.78)%,对照组为(23.21±2.34)%,空白组为(7.45±1.23)%;(2)血液中脂质含量:分别于1、2、4周检测血液中三酰甘油含量结果如下:空白组为(1.25±0.32)、(1.28 ±0.26)、(1.27±0.40) mmo/L;对照组为(2.17±0.23)、(2.48±0.41)、(1.88 ±0.38) mmo/L;实验组为(1.42±0.34)、(1.47±0.26)、(1.50±0.49) mmo/L.总胆固醇含量分别在1、2、4周变化:空白组:(1.62±0.13)、(1.62±0.14)、(1.62±0.19) mmo/L;对照组:(2.41±0.18)、(2.52±0.24)、(2.13±0.37) mmo/L;实验组:(1.64±0.18)、(1.69±0.24)、(1.66±0.31)mmo/L.(3)组织学检测:实验组与对照组比较,股骨头表面更加光滑,骨小梁大部分排列致密整齐,小部分区域出现萎缩,稀疏,断裂.结论 EPO可以降低空骨陷窝率,增加股骨头供血微血管数量,降低血液中的脂质含量,可以预防股骨头坏死的发生和进展. Objective To explore the preventive effect of recombinant human erythropoietin erythropoietin (EPO) on femoral head necrosis in rats.Methods Sixty male SD rats were randomly into three groups:blank group,control group,and experimental group.The control group was subdivided into two subgroups:subgroup A and subgroup B.The rats in subgroup A were injected with prednisone acetate 50 mg/kg in the root of the gluteal muscle on every Monday and Friday,once per day for 4 weeks,and those in subgroup B were injected with the same volume of sodium chloride injection of recombinant human erythropoietin erythropoietin (rhEPO,5 000 U/kg)three h before the modeling.Results The empty lacunae rate of hematoxylin and eosin (HE) stained sections in the experimental group,control group and blank group was (14.7 ± 1.78) %,(23.21 ± 2.34) %,and (7.45 ± 1.23) % respectively;At 1 st,2nd and 4th,blood triglyceride content was (1.25 ± 0.32),(1.28 ± 0.26) and (1.27 ± 0.4) mmo/L in blank group,(2.17 ±0.23),(2.48 ±0.41) and (1.88 ±0.38) mmo/L in control group,and (1.42 ±0.34),(1.47 ±0.26) and (1.50 ± 0.49) mmo/L in experimental group;the total cholesterol content was (1.62 ±0.13),(1.62 ±0.14) and (1.62 ±0.19) mmo/L in blank group,(2.41 ±0.18),(2.52±0.24) and (2.13 ±0.37) mmo/L in control group,and (1.64 ±0.18),(1.69 ±0.24) and (1.66 ± 0.31) mmo/L in experimental group.Histologically,the femoral head surface was more smooth in experimental group than control group.In experimental group,most of the trabecular bones arranged densely and regularly,and shrink,sparse,and fracture were seen in less regions.Conclusion EPO can reduce the empty lacunae rate,increase the microvessels in femoral head blood supply,reduce blood lipid levels,and prevent the progress of femoral head necrosis.
