【摘要】 1目的　观察半导体激光辐照疗法 (L ISCL T)对轻度认知障碍 (MCI)病人血清β-类淀粉样蛋白 (β-AP)的影响。2方法　选择临床确诊的 MCI病人进行半导体激光 (波长 6 70 nm ,功率 7～ 10 m W)鼻腔照射治疗 ,采用放射免疫分析法 (RIA )对 MCI病人治疗前后血清中的β- AP含量进行检测 ,并与对照组进行比较。3结果　治疗组血清β- AP较对照组明显增高 ,差异有显著意义 (t=3.48,P<0 .0 1) ;L ISCL T治疗 10次后 ,β- AP明显降低 ,与治疗前相比差异有显著意义 (t=3.5 7,P<0 .0 1)。4结论　 L ISCL T可影响β- AP的代谢过程 ,对延缓 MCI的发展具有一定的临床意义。更多还原

【Abstract】 Objective\ To observe the change of serum amyloid β protein (β AP) in patients with mild cognitive impairment(MCI) after semiconductor laser therapy(LISCLT).\ Methods\ The levels of serum β AP of patients with MCI were measured by radioimmunoassay(RIA) before and after LISCLT, the results were compared with the normal controls.\ Results\ The β AP of patients with MCI increased significantly compared with the control ( t=3.48, P <0.01), and decreased markedly after ten treatments of LISCLT( t=3.57, P <0.01).\ Conclusion\ The LISCLT may affect the metabolism of β AP in patients with MCI thus delaying the development of the disease.
