目的:
2
确定穴位局部的关键信号分子并探讨其在手针镇痛中的作用.
方法:
2
进行三步研究. 实验1
将12只Wistar大鼠随机分为对照组、对照+手针1组和对照+手针7组
对足三里穴区组织进行全基因组分析. 实验2
将大鼠分为生理盐水组、生理盐水+手针组和CFA+手针组
每组6只
进行足底PWL检测
并对足三里穴区组织中的NFκB p-p65、NFκB p-p50进行免疫组化和Western blot检测. 实验3
将24只大鼠分为生理盐水+DMSO组、CFA+DMSO组、CFA+DMSO+手针组和CFA+BAY 11-7082+手针组
进行足底PWL检测
并对足三里穴区组织中的NFκB p65进行免疫荧光检测.
结果:
2
(1) 在对照+手针7组中
Rela、Nfkb1、Nfkbia、Il1b、Il6、Cxcl1、Ccl2基因表达显著增加 (
P
<
0.05或
P
<
0.01). (2) 与CFA组相比
从针刺第1天至第7天
CFA+手针组PWL均显著提高 (
P
<
0.01). 与对照组和CFA组相比
Western blot结果与免疫组织化学一致
手针相关组的NFκB p-p65和NFκB p-p50表达显著增加 (
P
<
0.05). (3) 与CFA+DMSO+手针组相比
CFA+BAY 11-7082+手针组的PWL从第3天起显著下降
并持续到第5天和第7天 (分别为
P
<
0.05和
P
<
0.01)
且NFκB p65的表达也显著降低 (
P
<
0.01).
结论:
2
手针引起的穴位局部NFκB信号级联反应是其镇痛效应启动的重要步骤
为手针镇痛效应的启动提供了新的证据
提高了对针刺镇痛科学基础的认识
Objective:
2
To identify the prominent molecular signaling in acupoints and explore their roles in initiating the analgesia effect of manual acupuncture (MA).
Methods:
2
A three-step study was conducted
the experiment 1 was a genome-wide analysis of the tissue at acupoint Zusanli (ST 36)
including 12 Wistar rats which were divided into control
control+MA1
and control+MA7 groups. In the experiment 2
the paw withdrawal latency (PWL)
immunohistochemistry and Western blot analysis of phospho-nuclear factor kappa B (NFκB) p65 (p-p65)
phospho-NFκB p50 (p-p50) at ST 36 were performed on rats of saline
saline+MA
and complete Freund's adjuvant (CFA) +MA groups (
n
=6). In experiment 3
24 rats were divided into saline+DMSO
CFA+DMSO
CFA+DMSO+MA
and CFA+BAY 11-7082+MA groups
the PWL and immunofluorescence assay of NFκB p65 at ST 36 was conducted.
Results:
2
(1) The gene: inhibitor of NFκB (Nfkbia)
interleukin-1β (Il1b)
interleukin-6 (Il6)
chemokine c-x-c motif ligand 1 (Cxcl1)
monocyte chemoattractant protein-1 (MCP-1/Ccl2) expressions in the control+MA7 group were significantly increased (
P
<
0.05 or
P
<
0.01)
and the expression of NFκB p65 (Rela)
NFκB p50 (Nfkb1) were increased in the control+MA7 group (
P
<
0.05). (2) CFA+MA groups showed increased PWL from day 1 to 7 (
P
<
0.01 vs. CFA)
and the Western blot results were consistent with immunohistochemistry
the expression of NFκB p-p65 and NFκB p-p50 were significantly increased in the MA-related groups compared with control and CFA groups (
P
<
0.05). (3) Compared with the CFA+DMSO+MA group
the PWL of the CFA+ BAY 11-7082+MA group decreased significantly and continued until day 5 and 7 (
P
<
0.05 and
P
<
0.01
respectively)
and the NFκB p65 expression of CFA+BAY 11-7082+MA was significantly reduced compared with CFA+DMSO+MA (
P
<
0.01).
Conclusion:
2
Local NFκB signaling cascade in acupoint caused by MA is an important step in initiating the analgesic effect
which would provide new evidence for the initiation of MA-effect and improve the understanding of the scientific basis of acupuncture analgesia.
