氦氖激光血管体表照射临床观察

Clinical observation of He-Ne laser extravascular irradiation therapy

目的 根据光在人体组织的传播特性 ,研究氦氖激光沿血管体表照射的治疗效果、操作方法以及治疗费用等。希望将此法取代氦氖激光血管内照射疗法。方法 采用从光导纤维输出的2 5mW ,6 32 .8nm氦氖激光 ,对 30例脑血管病合并糖尿病、哮喘患者的静脉进行血管体表照射治疗 ,并检测其血糖、血脂及血液流变学部分指标的变化情况。结果 经治疗患者症状以及实验检测数据均有改善。平均血粘度下降 0 .2 5 ,血浆粘度下降 0 .0 5 ,纤维蛋白原下降 0 .17,血栓形成系数下降0 .32 ,胆固醇下降 0 .80 ,甘油三酯下降 0 .2 9,高粘度脂蛋白下降 0 .32 ,血糖亦明显下降。结论 激光沿血管体表照射治疗操作简单、安全 ,为无创伤性治疗 ,减少了穿刺、留置针与光纤光针等操作程序 ,避免了感染的可能性。激光沿血管体表照射有可能成为一种心、脑血管疾病临床治疗的新方法。

Objective According to the characteristic of light propagation on human tissues,the medical effect and cost as well as manipulative method of He-Ne laser extravascular irradiation on blood vessel were studied to replace the laser intravascular irradiation therapy hopefully.Methods The veins of 30 patients with cerebrovascular disease combined with diabetes or asthma were extravascularly radiated by He-Ne laser(632.8 nm,25 mW),which was delivered by optic-fiber.The values of blood sugar,blood-fat and hemorrheology were determined as the effective indexes.Results After experiment,the patient's symptoms and blood sugar were improved;the mean level of blood viscosity,plasma viscosity,fibrinogen,cholesterol,triglyceride,HDL-C and coefficient of thrombosis formation were respectively reduced 0.25, 0.05 ,0.17,0.80,0.29,0.32 and 0.32.Conclusion It is suggested that the laser extravascular irradiation therapy is a simple,safe,inexpensive and without side-effect therapy for the patients.It is likely to be a new medical method for cardio- and cerebrovascular diseases.
