目的:
2
观察针刺对急性心肌缺血大鼠心包经和心脏微循环灌注量的影响
评价针刺是否能同时影响经络和相应脏器. 并通过比较针刺不同经络的穴位
讨论其是否具有相同作用.
方法:
2
采用结扎大鼠左前降支的方法建立急性心肌缺血模型. 将32只大鼠随机分为4组
急性心肌梗死组、针刺内关组、针刺列缺组及针刺前三里组
每组8只. 另8只大鼠仅接受开胸手术作为假手术组. 针刺组大鼠分别在内关、列缺和前三里穴进行手针干预15分钟. 采用激光散斑灌注成像仪 (LPSI) 监测针刺前后心包经和心脏的微循环灌注量
并用PSI系统计算和分析灌注单位 (PU) .
结果:

0.05)
针刺干预后
上述指标明显降低 (
P
<
0.05) . 此外
前三里组HMP在针刺期间明显降低
尤其与针刺前比较
差异明显 (
P
<
0.05) .
结论:
2
针刺内关穴可明显提高急性心肌缺血模型大鼠心包经和心脏微循环灌注量

并且具有穴位特异性与经络传播效应.
Objective:
2
To observe the influence of acupuncture on microcirculation perfusion of the pericardium meridian and heart in acute myocardial ischemia (AMI) rats and evaluate whether acupuncture can simultaneously affect the meridians and corresponding viscera. Additionally
acupoints at different meridians were compared and whether they exert the same effects was discussed.
Methods:
2
Totally 32 Sprague-Dawley rats were subjected to left anterior descending (LAD) ligation to develop an AMI model. Rats were divided into 4 groups
including AMI
acupuncture Neiguan (PC 6)
Lieque (LU 7) and Qiansanli (LI 10) groups (
n
=8). Eight rats received only thoracotomy (sham-operated group). The rats in the acupuncture groups received manual acupuncture at PC 6
LU 7 and LI 10 acupoints for 15 min
respectively. The microcirculation perfusion of pericardium meridian and heart was monitored by laser speckle perfusion imager (LSPI) before
during and after acupuncture manipulation for 15 min. Subsequently
the perfusion unit (PU) was calculated and analyzed by PSI System.
Results:
2
After LAD
compared to pre-acupuncture stage
the heart microcirculation perfusion (HMP) in the AMI group decreased continuously at during-acupuncture (
P
>
0.05) and post-acupuncture stages (
P
<
0.05)
and the pericardium meridian microcirculation perfusion (PMP) showed no significant differences at 3 stages (
P
>
0.05). Compared to pre-acupuncture stage
the PMP and HMP in PC 6 group significantly increased during acupuncture manipulation (both
P
<
0.05)
and PMP decreased obviously after acupuncture (
P
<
0.05). The PMP in the LU 7 and LI 10 groups were slightly elevated (both
P
>
0.05); however
they were significantly reduced after acupuncture manipulation (both
P
<
0.05). Additionally
HMP of LI 10 group was decreased significantly during acupuncture
especially compared to pre-acupuncture stage (
P
<
0.05).
Conclusions:
2
Acupuncture at PC 6 obviously increased the PMP and HMP in AMI rats
and the effects were superior to at LU 7 and LI 10 acupoints. It was further confirmed that acupuncture promoted qi and blood circulation
indicating that acupoint specificity exists and features a meridian-propagated effect.
