0.01)。结论:艾灸可以减轻IBS-D大鼠肠道炎性反应水平,降低内脏高敏感性,其机制可能与提高结肠组织miR-345-3p、miR-216a-5p表达水平,抑制NF-κB p65表达水平,从而降低炎性因子水平有关。Objective To observe the effect of moxibustion on the expression of miR-345-3p
miR-216a-5p and nuclear factor-κB p65(NF-κB p65) in colonic tissue of rats with diarrhea-predominant irritable bowel syndrome(IBS-D)
so as to explore its anti-inflammatory mechanism in relieving IBS-D. Methods SD rats were randomly divided into normal control(n=12)
model(n=12)
moxibustion(n=12) and ammonium pyrrolidine dithiocarbamate(PDTC
n=12) groups. The IBS-D model was established by neonatal mother-child separation combined with acetic acid enema stimulation and chronic binding methods. The rats in the moxibustion group received moxibustion stimulation of “Tianshu”(ST25) and “Shangjuxu”(ST37) for 20 min
once a day
for 7 days
and those of the PDTC group received intraperitoneal injection of PDTC(50 mg·kg(-1))

(-1)
·d(-1)·d
(-1)
) once daily for 7 days. After the intervention
the body weight
loose stool rate and the minimum volume threshold of abdominal withdrawal reflex(AWR) were observed
and histopathological changes of colonic mucosa were observed by HE staining. The contents of interleukin-1β(IL-1β)
interleukin-4(IL-4)
interleukin-6(IL-6) and tumor necrosis factor α(TNF-α) in serum were measured by ELISA. The expression of miR-345-3p
miR-216a-5p and NF-κB p65 mRNA in the colon tissue were detected by quantitative real-time PCR
and the immunoactivities of IL-1β
IL-6
TNF-α and NF-κB p65 in the colon tissue were determined by immunofluorescence histochemistry. Results Compared with the normal control group
the loose stool rate
contents of IL-1β
IL-6 and TNF-α
experssion of NF-κB p65 mRNA and the immunoactivities of IL-1β
IL-6
TNF-α and NF-κB p65 were significantly increased(P
<
0.01)
whereas the body weight
minimum volume threshold of AWR
content of IL-4
and the relative expression of miR-345-3p and miR-216a-5p were remarkably decreased in the model group(P
<
0.01). In comparison with the model group
the loose stool rate
contents of IL-1β
IL-6
TNF-α
expression of NF-κB p65 mRNA and the immunoactivities of IL-1β
IL-6
TNF-α and NF-κB p65 were considerably down-regulated(P
<
0.01)
while the content of IL-4 and the relative expressions of miR-345-3p and miR-216a-5p were obviously up-regulated in both moxibustion and PDTC groups(P
<
0.01
P
<
0.05). The content of IL-6 in serum was significantly lower in the PDTC group than in the moxibustion group(P
<
0.01). Conclusion Moxibustion can reduce the level of intestinal inflammation and visceral hypersensitivity in IBS-D rats
which may be related to its functions in increasing the expression levels of miR-345-3p and miR-216a-5p and in inhibiting the expression of NF-κB p65
