Methods: A analysis of the clinical data of 56 cases of biological feedback treatment of the outlet obstructive constipation was made. Results: Among 54 cases who completed the biological feedback treatment, the results of rectal manometer detection
in 35 cases indicated that the rectum sensitivity threshold and the maximum tolerance capacity and recto-anal inhibitory reflex decreased, compared with those before treatment. Paradoxical contraction of pelvic floor disappeared and normal bowel movement was regained;in cases the symptoms were improved, including times of bowel Hydroxychloroquine molecular weight movement, functional
constipation and anorectic distention. The effective rate of biofeedback treatment was 92.6%. Only 4 cases were ineffective and 2 cases stopped treatment. Conclusion: The short-term effect of biological feedback treatment for the outlet obstructive constipation is satisfactory, and has advantages of low cost and no need for hospital admission.

Our study aimed to explore the effects and mechanism of ghrelin after intracerebroventricular (ICV) injection on the interdigestive myoelectric complex (IMC) in rats. Methods: (1) In the electrophysiologic experiment, two pairs of silver electrodes were implanted in the duodenum and jejunum. Rats were received ICV injection of ghrelin (6.4 μg kg −1) during fasting. Some rats were pretreated with intravenous injection of phentolamine, propranolol and atropine respectively. Other groups of rats were received ICV injection of anti-neuropeptide Y (NPY) IgG and (D-Lys3) GHRP-6 before ghrelin injected. (2) The c-Fos activation on the central nervous system (CNS) and enteric nervous system (ENS) through ICV injection of ghrelin was studied by the immunohistochemistry. Results: (1) Ghrelin showed an excitatory effect on the IMC. This effect was inhibited by atropine, anti-NPY IgG and (D-Lys3) GHRP-6, but not by propranolol and phentolamine.
