目的 观察低能量氦氖激光血管内照射（ＩＬＩＢ）对 ２型糖尿病患者红细胞变形能力（ＲＢＣＤ）和Ｎａ＋－Ｋ＋－ＡＴＰ酶的影响。方法９８例糖尿病患者应用 ＩＬＩＢ治疗，每日１次，每次６０ｍｉｎ，检测治疗前后 ＲＢＣＤ和红细胞 Ｎａ＋－ Ｋ＋－ ＡＴＰ酶活性。结果 ２型糖尿病患者 ＲＢＣＤ及红细胞 Ｎａ＋－ Ｋ＋－ ＡＴＰ酶的活性较正常对照组均明显减低，而各糖尿病组经激光治疗１０ｄ后，其ＲＢＣＤ及Ｎａ＋－Ｋ＋－ＡＴＰ酶活性较治疗前有明显提高（Ｐ＜０．０５）。结论ＩＬＩＢ可提高２型糖尿病患者ＲＢＣＤ及红细胞Ｎａ＋－Ｋ＋－ＡＴＰ酶活性。
Objective To investigate the effects of low energy He-Ne laser intravascular irradiation (ILIB) on erythrocyte deformability (RBCD) and Na + -K + -ATPase in type 2 diabetic patients. Methods Ninety - eight diabetic patients were treated with ILIB once a day for 60 minutes. The activities of RBCD and erythrocyte Na + - K + - ATPase were measured before and after treatment. Results The activities of RBCD and erythrocyte Na + - K + - ATPase in type 2 diabetic patients were significantly lower than those in normal control group. The activity of RBCD and Na + -K + -ATPase in diabetic patients after laser treatment for 10 days were significantly higher than those before treatment (P <0.05). Conclusion ILIB can increase RBCD and erythrocyte Na + -K + -ATPase activity in type 2 diabetic patients.
