To observe the effects of electroacupuncture (EA) at different acupoints on the expression of N-methyl-D-aspartate receptor (NMDA receptor ) and behaviors in irritable bowel syndrome (IBS) rats.<jats:italic>Methods<\/jats:italic>. Wistar rats were randomly divided into blank control group (blank group, n=10) and model preparation group (n=50); experimental rat model of IBS was established by the \u201cneonatal maternal separation and acetic acid enema\u201d combined with \u201ccolorectal distension stimulation\u201d method. A total of 50 IBS rats were randomly assigned to five groups of 10 each: model group, Yintang (GV29) group, Neiguan (PC6) group, Tianshu (ST25) group, and Zusanli (ST36) group. Rats in four treatment groups, aged 9 weeks old, were treated with EA by HANS with a sparse-dense wave with a frequency of 2\/100 Hz, current of 0.1-0.3mA, and 20 min\/stimulation, every other day for a total of 5 sessions. After treatment, the abdominal visceral sensitivity was evaluated by abdominal withdrawal reflex (AWR), and the psychological and emotional behavior of rats were evaluated by the open-field test (OFT). The expression of NMDA receptors in anterior cingulate cortex (ACC) was detected by Quantitative Real-time PCR, and the positive expression of NMDA receptors in colon was detected by immunohistochemistry.<jats:italic>Results<\/jats:italic>. The IBS rat\u2019s abdomen is more sensitive and irritable; NR1, NR2A, and NR2B in ACC and NR1 and NR2B in colon of rats significantly increased in the model group versus the normal group (P&lt;0.01) and were inhibited in all treatment groups (P&lt;0.01, P&lt;0.05). Additionally, NR2A and NR2B in ACC reduced more in GV29 group (P&lt;0.01) than in other treatment groups (P all&lt;0.05) compared with the model group. The expression of NR2B in colon was significantly inhibited in ST36 group (P&lt;0.01) and inhibited in GV29 group and ST25 group (P all &lt;0.05) compared with the model group. And the expression of NR2B in colon was more inhibited in ST36 group than in PC6 group (P&lt;0.01).<jats:italic>Conclusions<\/jats:italic>. EA at different acupoints could obviously relieve abdominal pain and abnormal behaviors in IBS rats in different degrees of effects. The effect of abdominal pain-relief, from greatest to least, is ST25, ST36, GV29, and PC6, while the effect of relieving abnormal behaviors caused by IBS, from greatest to least, is GV29, PC6, ST36, and ST25. There are significant differences in the expressions of NMDA receptors in ACC and colon among different acupoints. This difference should be related to the location distribution and indications of acupoints.<\/jats:p>","DOI":"10.1155\/2019\/4213928","type":"journal-article","created":{"date-parts":[[2019,2,3]],"date-time":"2019-02-03T23:32:58Z","timestamp":1549236778000},"page":"1-12","source":"Crossref","is-referenced-by-count":25,"title":["Effect
