慢性肾功能不全患者血浆神经肽Y变化及黄芪对其影响的研究

目的 :探讨慢性肾功能不全 ( CRF)患者血浆神经肽 Y( Neuropeptide Y,NPY)含量及临床意义 ,研究黄芪对 CRF患者血浆 NPY的影响。方法 :采用放射免疫分析法测定 4 0例 CRF患者应用黄芪注射液前后血浆 NPY含量变化。结果 :1CRF患者血浆 NPY含量明显高于正常健康组 ,且尿毒症期患者 NPY含量明显高于氮质血症期 ;2 CRF患者血浆 NPY含量与平均动脉压 ( MAP)、血清肌酐值( CRE)均呈正相关 ;3经黄芪治疗 3周后 ,实验组血浆 NPY含量明显降低 ,对照组无明显变化。结论 :CRF患者体内存在 NPY的合成、分泌或代谢失调 ,与 CRF发生、发展有密切相关 ,黄芪可影响CRF患者血浆 NPY含量 ,有益于改善肾功能。

Change of neuropeptide Y in plasma in chronic renal failure pat ients and the effects of Astragalus on it

Objective:To study the change of Neuropeptide Y (NPY) plasma and its clinical si gnificance and the effects of Astragalus on NPY in plasma in chronic renal fail ure patients.Methods:Radioimmunoassay was used to measure plasma concentration of NPY.Results:①The plasma concentration of NPY in CRF patients was significantly high er than tha t in healthy group,and the plasma concentration of NPY in uremia patients was si gnificantly higher than that in nitremia patients.②The plasma concentration of NPY was positively correlated with the serum value of CRE and the level of MAP in CRF patients.③After Astraglus treatment for 3 weeks,the level of NPY in plas ma was significantly decreased in experiment group,but in control group,there wa s no significant change.Conclusion:The disturbance in synthesis,secretion or metabolism of NPY occurred in CRF patients,which significantly correlates with the occurrence and development of CRF.Astraglus can influence the NPY in plasma in CRF patients,so as to improve the renal function.
