目的:创建适宜Plexon信号采集系统的帕金森病(PD)大鼠行为学评价体系,对PD大鼠运动缺陷症状进行量化评测。方法选取成年雄性Wistar大鼠18只,随机分为对照组8只,实验组10只,实验组大鼠建立PD模型,有8只大鼠PD模型鉴定成功,2组大鼠手术置入脑内电极。2组大鼠使用自制跑步机、多通道在体记录系统分别进行最长运动时间、步频、失误次数和不连续运动频率量化评测,对9~30 r/min旋转速度(转速)筛选,并组织学鉴定。结果与对照组大鼠比较,在20和30 r/min转速评测中,实验组最长运动时间显著变短[(18.03±2.74) min vs (26.98±0.91)min;(3.33±1.45)min vs (26.67±0.71)min],失误次数显著增多[(7.50±0.76)次 vs (1.50±0.43)次;(10.00±0.00)次 vs (2.00±0.58)次],步频显著降低[(73.33±7.00)步/min vs (95.50±4.94)步/min;(76.33±7.41)步/min vs (110.33±7.58)步/min ,P<0.05,P<0.01];在9和15 r/min转速评测中,实验组最长运动时间、步频均无明显变化,差异无统计学意义(P>0.05);在9和30 r/min转速评测中,实验组不连续运动频率显著降低,在15和20 r/min转速评测中,实验组不连续运动频率显著升高[(2.00±0.31)次/min vs (0.70±0.21)次/min;(7.00±0.37)次/min vs (1.00±0.33)次/min ,P<0.05,P<0.01]。结论行为学评价体系有效地评价了PD大鼠对高转速控制能力差,运动协调性差的运动缺陷症状,筛选出了12 r/min为适宜的转速。

Objective To quantitatively evaluate the motor deficit symptoms of PD and screen the appropriate rotation speed of electrical signals in rat brain under continuous motion by construc‐ting PD rat behavior evaluation system .Methods Eighteen adult male Wistar rats were randomly divided into control group (n=8)and experimental group (n=10) .Electrodes were implanted into the rat nuclei after a rat PD model was established .The longest moving time ,step frequency ,slip up times and discontinuous moving frequency were recorded using self‐made treadmill and multi‐channel in vivo recording instrument .The 9-30 r/min rotation speed was screened and histology was identified .Results The longest moving time was significantly shorter ,the slip up times were significantly more ,and the step frequency was significantly higher in experimental group than in control group when the 20 r/min rotation speed and 30 r/min rotation speed were evaluated (P<0.05 ,P<0 .01) .The discontinuous moving frequency was significantly lower when the 9 r/min rotation speed and 30 r/min rotation speed were evaluated and significantly higher when the 15 r/min rotation speed and 20 r/min rotation speed were evaluated (P<0 .05 ,P<0.01) .Conclusion The PD rat behavior evaluation system can effectively evaluate the motor deficit symptoms of PD and screen the appropriate rotation speed .
