脑血管病（ＣＶＤ）为危险人类健康最常见的疾病之一，具有很高的发病率、复发率、致残率和死亡率，目前尚无特异的临床疗法。我们应用血管内激光照射血液疗法（ＩＬＩＢ）治疗３４４７例ＣＶＤ患者，总有效率达９０％以上，尚伴有某些实验室指标的改善，包括改善血液流变学性质和血液动力学参数及组织器官的微循环灌注，提高红细胞变形能力和膜稳定性，纠正脂代谢异常，并具有抗氧化和解毒效应。另外，ＩＬＩＢ尚可刺激免疫系统。作者还讨论了ＩＬＩＢ作用的可能机制 Cerebrovascular disease (CVD) is one of the most common diseases in dangerous human health. It has high morbidity, relapse rate, disability rate and mortality. There is no specific clinical therapy. We treated 3447 patients with CVD with endovascular laser irradiation (ILIB), with an overall response rate of 90% or more, with improvements in certain laboratory parameters including improvement in hemorheological properties and hemodynamic parameters and tissue Microcirculation of organs perfusion, improve erythrocyte deformability and membrane stability, correct lipid metabolism, and has antioxidant and detoxification effects. In addition, ILIB can stimulate the immune system. The authors also discuss possible mechanisms of ILIB action
