益气活血方联合运动康复疗法对脑梗死恢复期偏瘫肢体功能及表面肌电图的影响

目的 探讨益气活血方联合运动康复疗法对脑梗死恢复期患者偏瘫肢体功能恢复及表面肌电图（surface electromyography, sEMG）的影响。方法 将符合入选标准的80例脑梗死恢复期患者采用随机数字表法分为2组，每组40例。康复治疗组在对症治疗基础上配合偏瘫运动康复治疗，联合治疗组在康复治疗组基础上加服益气活血方。2组均1个月为1个疗程，共治疗3个疗程。分别于治疗前及各疗程结束后进行患侧上肢Fugl-Meyer量表（Fugl-Meyer Assessment, FMA）评分，采用表面肌电图仪检测偏瘫侧肱二头肌表面肌电图（surface electromyography, sEMG）最大等长收缩肌电图波形的均方根值（root mean square, RMS）和中位频率值（median frequency, MDF）。结果 治疗后1、2、3个月，联合治疗组FMA评分均高于康复治疗组（t值分别为2.702、4.595、4.444，P值均＜0.01）。治疗后2、3个月，联合治疗组RMS值（t值分别为7.188、5.405，P值均＜0.01）与MDF值（t值分别为3.336、4.584，P值均＜0.01）均高于康复治疗组。结论 益气活血方联合运动康复疗法可改善脑梗死恢复期患者偏瘫侧上肢的运动功能，提高肌张力。

Reaction dynamics between the photonuclease triplet- excited vitamin-K3 and gua-nine nucleotide

Nanosecond laser pulse photolysis was used to investigate the excited-state dynamics of the photonuclease vitamin-K3 (VK3). A spectral band peaked at 285 nm was newly observed and attributed to the triplet-excited state of VK3. In studying the photochemistry between the photonu-clease VK3 and guanine nucleotide (dGMP), we obtained spectroscopic evidence for the photo-initiated formation of both VK3 radical anion and dGMP radical cation, and thus proved the charge transfer reaction between the trip-let-excited VK3 and the ground-state dGMP.
