[Effect of electroacupuncture of "Hegu" (LI4) and "Zusanli" (ST36) on intestinal sensitivity and motility in irritable bowel syndrome rats].

Objective: To observe the effect of electroacupuncture (EA) of "Hegu"(LI4) and "Zusanli"(ST36)on changes of intestinal sensitivity and colonic motility and expression of colonic 5-hydroxytryptamine 3A receptor (5-HTR) in irritable bowel syndrome (IBS) rats, so as to reveal its mechanism underlying improvement of IBS.

Methods: A total of 40 neonatal Wistar rats were randomly and equally divided into normal control, model, LI4 and ST36 groups (＝10). The IBS model was induced by mother-infant separation, acetic acid enema and colorectal distension (CRD).

[Comparison of effects of electroacupuncture at "Tianshu" (ST25) and "Dachangshu" (BL25) on intestinal sensitivity and expression of muscarinic MR and 5-HTR in irritable bowel syndrome rats].

Objective: To observe and compare the effect of electroacupuncture (EA) of "Tianshu" (ST25) and "Dachangshu" (BL25) on intestinal sensitivity and the expression of M muscarinic acetylcholine receptor (MR) and 5-hydroxytryptamine 3A receptor (5-HTR) in the colon tissue in irritable bowel syndrome (IBS) rats, so as to explore its mechanism underlying improvement of IBS.

Methods: Forty newborn Wistar rats were randomly divided into blank control, model, ST25 and BL25 groups (＝10 rats per group). The IBS model was established by joint application of maternal separation, acetic acid enema plus colorectal distension from day 8 to 21 after birth.

[Relativity and integrality of the acupoint effect specificity].

The researches on the acupoint effect specificity were summarized to explore whether the integrality of the acupoint effect specificity existed and analyze the connection between the relativity and integrality of the acupoint effect specificity. The literature on the clinical and experimental researches relevant with the acupoint effect specificity was retrieved through CNKI from January 2007 to October 2017. A total of 39 papers met the retrieving criteria.

[Effect of Electroacupuncture at "Neiguan" (PC 6) and "Tianshu" (ST 25) for Colonic Motility and D 2 Receptor in Irritable Bowel Syndrome Rats].

Objective: To observe and compare the effects of electroacupuncture (EA) at "Tianshu" (ST 25) and "Neiguan" (PC 6) for colonic motility and the expression of colon dopamine D 2 in irritable bowel syndrome (IBS) rats, and to explore the specificity of different meridians and different acupoints.

Methods: Forty Wistar newborn rats were randomly divided into blank, model, Tianshu and Neiguan groups. Separation of mother and child and acetic acid coloclyster combined with colorectal distension were used to establish IBS model in the model, Tianshu and Neiguan groups.
