摘要

目的：

观察补肾方药（左归丸）、益气方药（益气聪明汤）及两方合用（合剂）对老年大鼠空间学习能力及学习记忆相关基因表达变化的影响，并探索相关表观遗传酶的变化。

方法：

以自然衰老（24月龄）SD雄性大鼠为动物模型，随机分为老年组，左归丸组（12.12 g·kg

－1

），益气聪明汤组（10.18 g·kg

－1

），合剂组（11.15 g·kg

－1

）和老年皮质酮（glucocorticoid，GC）拮抗组（5×10

－3

g·kg

－1

），另设青年组（同品系5月龄）。采用Morris水迷宫法观察各组大鼠空间记忆能力，激光共聚焦法观察各组大鼠大脑海马区乙酰化酶2（histone deacetylase 2，HDAC2）与甲基化CpG岛结合蛋白2（methyl CpG binding protein 2，MeCP2）的共定位情况，蛋白免疫印迹法（Western blot）检测海马组织HDAC2，组蛋白乙酰转移酶1（histone acetyltransferase 1，HAT1），糖皮质激素受体（glucocorticoid receptor，GR），突触蛋白I（synapsin

Syn-1）表达变化，实时荧光定量聚合酶链式反应（Real-time PCR）检测HDAC2 mRNA的表达及各药物对上述指标异常变化的改善作用。

结果：

与青年组（正常组）比较，老年组（模型组）大鼠潜伏期显著延长（

0.05），穿越平台次数显著减少（

0.05）；与老年组（模型组）比较，左归丸组、益气聪明汤组大鼠潜伏期显著缩短（

0.05），穿越平台次数有所增加。与青年组比较，老年组大鼠HDAC2蛋白与mRNA表达显著增多（

0.05

0.01），且在细胞核内与MeCP2的共表达明显增多；HAT1，GR和Syn-I表达显著降低（

0.05

0.01）。各给药组均能不同程度改善上述指标的异常变化，但益气方药以及两方合剂对HAT1无改善作用。

结论：

补肾方药左归丸、益气方药益气聪明汤可通过增加老年大鼠学习记忆相关蛋白GR，Syn-1与表观遗传修饰酶HAT1的表达，降低HDAC2的表达，并同时减少HDAC2蛋白与MeCP2的细胞核内共定位，以改善老年大鼠空间学习记忆能力。

Abstract

Objective:

To observe the effects of recipes for tonifying kidney and replenishing Qi

Zuoguiwan (ZG) and Yiqi Congming Tang(YQ) on memory capacity

expressions of learning and memory-related genes expression

and explore the changes in relevant epigenetic modification enzymes.

Method:

SD male rats with natural aging (24 months old) were used as animal models and randomly divided into aged control group

aged ZG group(12.12 g·kg

-1

)

aged YQ group(10.18 g·kg

-1

)

aged compound group(11.15 g·kg

-1

) and aged antagonist RU38486 group(5×10

-3

g·kg

-1

). Another 5 months old male SD rats were included as the young control group. Morris water maze method was used to observe the spatial learning and memory ability of the rats. The co-localizations of histone deacetylase 2 (HDAC2) and methyl CpG binding protein 2 (MeCP2) in hippocampus of rats in each group were observed by laser confocal microscope. The changes in expressions of glucocorticoid receptor (GR)

synapsin1(Syn-1)

HDAC2

and histone acetyltransferase 1(HAT1) proteins in hippocampus of each group were detected by Western blot

and mRNA expression of HDAC2 was detected by Real-time fluorescence quantitative polymerase Chain reaction (Real-time PCR). At the same time

the effects of ZG

YQ and compound decoction in alleviating the above-mentioned abnormal changes were observed.

Result:

Compared with the young control group(control group)

the latency of the aged control group was significantly prolonged (

0.05)

the number of crossing platforms was significantly reduced (

0.05); compared with the aged control group(model group)

the latencies of the ZG group and the YQ group were significantly shortened (

0.05)

and the numbers of crossing platforms were increased. Compared with the young control group

the protein and mRNA expressions of HDAC2 in the aged control group were significantly increased (

0.05

0.01)

and the co-expression with MeCP2 in the nucleus was significantly increased; and the expressions of HAT1

GR and Syn-1 were significantly decreased(

0.05

0.01). ZG

YQ and compound can all alleviate the abnormal changes of the above indicators to varying degrees

but the YQ and the compound group had no effect on HAT1.

Conclusion:

ZG group

YQ group

and compound group can improve the spatial learning and memory abilities of aged rats by increasing the expression of learning-memory-associated protein GR and epigenetic modification enzyme HAT1

and reducing the expression of HDAC2 and the co-localization of HDAC2 protein and MeCP2 in the nucleus.
