Objective:To investigate the effect of anesthesia on the cognitive status damage and MMP-2expression in ***:A total of 120 healthy rats were selected and randomly divided into the control group,CF3-CH(OCH2F)-CF3(Sevoflurane)group and CF3-CH2-O-CHF-CF3group(Sevoflurane)(n=40).After training for 3 d by the Morris water maze,the control group were injected with fentanyl for analgesia,the CF3-CH(OCH2F)-CF3 group and the CF3-CH2-O-CHFCF3 group were anesthesia with CF3-CH(OCH2F)-CF3 and CF3-CH2-O-CHF-CF3 on the basis of fentanyl,then rats in three groups underwent open surgery and suture conventional *** water maze was used to measure the rats cognitive ability in three groups on the 1st d,3rd d,5th d and 7th d,and the brain tissue MMP-2 expression was ***:After1 d/7 d of the surgery,Morris water maze performance and MMP-2 expression were not significantly different among three groups(P>0.05);After 3 d/5 d of the surgery,compared with the control group,the Morris water maze test result was significantly worsened,MMP-2expression levels were significantly increased(P<0.05);After 3 d/5 d of the surgery,compared with the CF3-CH2-O-CHF-CF3 group,Morris water maze test result of CF3-CH(OCH2F)-CF3group was significantly worsened,MMP-2 expression levels were significantly increased(P<0.05).Conclusions:Anesthesia can cause some injury on cognitive status,different anesthetic drugs may cause different injury,and the cognitive status injury is related to the MMP-2 expression.

目的利用静息态功能磁共振成像中的分数低频振幅(fractional amplitude of low frequency fluctuation,fALFF)技术研究中高度近视患者的脑功能改变,探讨其与近视患者临床资料的相关性。方法选择21例中高度近视患者为近视组,选择21名年龄、性别相匹配的健康志愿者为正常对照组,对入选者行静息态功能磁共振fALFF扫描。比较近视组与正常对照组大脑功能活动fALFF值的差异,并且分析fALFF改变的脑区与近视患者临床资料的相关性。结果相比于正常对照组,近视组在左侧额下回、壳核与右侧额下回、壳核、岛叶等区域fALFF值显著减低(均为P0.05)。结论近视患者伴随着多个脑区的神经元活动异常,这些脑区异常可能反映近视患者在语言理解和注意力控制方面可能存在功能障碍。
