摘要
用放免法测定62例肺心病并发呼吸衰竭患者的血清和尿β2—微球蛋白（β2—MG）水平，并以77例健康人为对照。结果表明肺心病并呼衰者血清和尿β2—MG明显高于对照组，且呼衰急发期明显高于缓解期（P＜0．01）。血清β2—MG与Cr和BUN呈正相关（r＝0．393和0．484，P＜0．01），尿β2—MG与血Cr和BUN亦呈正相关（r＝0．194，和0．217），但无统计学意义（P＞0．05）同时还发现血清和尿β2—MG与PaO2呈负相关（r＝－0．293，和－0．258，P＜0．05），与PaC（）。呈正相关（r＝0．384，和0．357，P＜0．01）。提示肺心病肾功能改变与呼衰有关，血清及尿的β2—MG水平可能是识别患者肾功能的较敏感指标。
Serum and ucine β2-MG levels were determined in 62 patients with cor pulmonale who had respiratory failure and in 77 healths using radio immunoassay The results showed that serum β2-MG and urine β2-MG levels in the patients were much higher than that in control, and were also higher in acute phase of respi-ratory failure than that in remisslon phase. Statistical analysis revealed that serum β2-MG levels possitively correlated with Cr and BUN(r=0. 393,and 0. 484,P<0.01 ) and urine β2-MG levels also possitively correlated with Cr and BUN (r = 0.194,and 0. 217), but no signiflcance in statistics (P>0.05 ). The results also showed that serum β2-MG and urine β2-MG levels negatively correlated with PaO2(r=0.293, and -0. 258,P<0.05),and possitively correlated with PaO2 r=0. 384 and 0.357,P<0.01). We suggest that renal function changes in cor pulmonale correlate with respiratory failure,and β2-MG may be a sensitive marker for identifying re-nal dysfunction in cor pulmonale with respiratory failure.
