摘要
目的 评价老年全身麻醉患者血清脂联素(adiponectin,ADP)及基质金属蛋白酶-9(matrix metalloproteinase-9,MMP-9)水平与术后认知功能障碍(postoperation cognitive dysfunction,POCD)的关系.方法 择期全身麻醉下行全髋关节置换术老年患者98例,年龄65岁~83岁,美国麻醉医师协会(ASA)分级Ⅰ~Ⅱ级,性别不限.所有患者分别于手术前3d及术后1、2、3、7d采用蒙特利尔认知评估表(montreal cognitie assessment,MoCA)评估认知功能,并采集空腹静脉血标本测定血清ADP及MMP-9水平.根据术后3d是否发生POCD分为POCD组和无POCD组.结果 28例患者发生POCD,发生率为28.5%,POCD组患者术后1、2、3d及7d血清MMP-9水平[(537±68)、(481±64)、(432±64)、(393±48) μg/L]较术前[(293±50) μg/L]明显升高(P<0.05),血清ADP水平[(4.3±1.6)、(4.7±1.2)、(5.1±1.6)、(6.0±1.1) mg/L]较术前[(9.39± 1.36) mg/L]明显下降(P<0.05).无POCD组术后1、2d血清MMP-9水平较术前明显升高(P<0.05),血清ADP水平较术前明显下降,术后3d均恢复至术前水平.组间比较,POCD组术后各时间血清MMP-9水平明显高于无POCD组[(439±53)、(387±66)、(301±67)、(296±54)μg/L](P<0.05);而ADP水平均明显低于无POCD组[(5.7±1.0)、(6.7±1.4)、(9.1±1.0)、(9.4±1.2)mg/L] (P<0.05).直线相关分析:POCD组患者血清MMP-9水平与MoCA评分呈负相关(r=-0.833,P<0.01),ADP水平与MoCA评分呈正相关(r=0.513,P<0.01).结论 老年全麻患者术后血清ADP水平下降与MMP-9水平升高可能参与了POCD发生的病理生理过程.
Objective To evaluate the reIationship of the serum levels of adiponectin (ADP),matrix metalloproteinase-9 (MMP-9) and postoperative cognitive dysfunction (POCD) in elderly patients after general anesthesia.Methods Ninety eight ASA Ⅰ or Ⅱ patients,aged 65 y-83 y,scheduled for artificial hip replacement under general anesthesia were studied.Cognitive functionwas assessed by Montreal Cognitie Assessment (MoCA),at 3 d before the operation and 1,2,3 d and 7 d after operation,and venous blood samples were collected for determination of serum ADP and MMP-9 levels at the same time in all patients.Patients were divided into POCD group and non-POCD group according to the occurrence of POCD in 3 d after operation.Results Twenty eight patients developed POCD (28.5%).Compared with the preoperative levels (293±50) μg/L,the serum levels of MMP-9 [(537±68),(481±64),(432±64),(393±48) μg/L] were significantly increased at 1,2,3 d and 7 d after operation,and the serum levels of ADP [(4.3±1.6),(4.7±1.2),(5.1±1.6),(6.0±1.1) mg/L] were significantly declined at 1,2,3 d and 7 d after operation compared with the preoperative levels (9.39±1.36) μg/L in group POCD (P〈0.05).Compared with that of preoperation,the serum levels of MMP-9 were significantly increased,and the serum levels of ADP were significantly declined on 1,2 d in group non-POCD.The serum levels of MMP-9 in group POCD,were significantly higher than that in group non-POCD [(439±53),(387±66),(301± 67),(297±54) μg/L](P〈0.05) at 1,2,3,7 d after operation.Compared with group POCD,the serum levels of ADP [(5.7±1.0),(6.7±1.4),(9.1±1.0),(9.34±1.2) mg/L] were significanfly higher in group non-POCD (P〈0.05) at 1,2,3,7 d after operation.Correlation analysis showed that the serum levels of MMP-9 were negatively correlated with MoCA score (r=-0.833,P〈0.01),the serum 1evels of ADP were positively correlated with MoCA score (r=0.513,P〈0.01).Conclusions An decreased postoperative serum ADP level and an increased postoperative serum MMP-9 level may be involved in the pathophysiological process of POCD in elderly patients with general anesthesia.
