Objective To investigate the variety of antro duodenal motility in patients with diarrhea or constipation predominant irritable bowel syndrome (IBS) and to elucidate the pathophysiology of IBS. Methods After 6 hours fasting, 17 patients with IBS (diagnosed by Rome Ⅱ criteria), 8 with diarrhea predominant diarrhea(D IBS) and 9 with constipation predominant IBS(C IBS), were investigated by gastrointestinal manometry (STD Co., Sweden) for recording at least 2 intergrated interdigestive migrating motor complex (MMC) cycles and observing 2 hours of postprandial antro duodenal motility. Results The MMC periods was shorter, phase Ⅲ duration was longer and amplitude was higher in D IBS group than in controls, whereas the MMC periods was longer and the phase Ⅲ duration was shorter in C IBS group than in controls. The duration of discrete clustered contraction(DCC) in phase Ⅱ was longer in IBS groups than in health controls, but there was no significant difference between the C IBS group and the D IBS group. The motility index in late phase Ⅱ and phase Ⅲ was higher in IBS D group, but for the IBS C group the motility index had no statistical difference from that for controls. The postprandial motility pattern of duodenum had no remarkable difference between IBS patients and controls. Conclusions The gastrointestinal motility disorders are apparent in the IBS patients. There is close relation between gastrointestinal motility disorders and the symptoms of the IBS patients. DCCs waves may almost be independent of constipation or diarrhea of IBS.

After COVID -19, patients, medical workers and the whole society in COVID -19 were faced with the challenge of how to quickly return to normal life. Patients cured in COVID -19 would face mental or psychological barriers, or be discriminated against, or face problems such as overweight of local epidemic prevention policies. The front-line medical personnel experienced job burnout and a variety of mental and psychological disorders, with some even developing physical symptoms. During the epidemic, ordinary people were in a state of psychological stress, education, production and economic activities were affected, and the incidence of mental or psychological disorders increases. It was necessary to provide COVID -19 patients with mental health monitoring and counseling. Give professional guidance to front-line medical staff, arrange rotation reasonably, and pay attention to their mental health status. Local governments should strictly implement the national epidemic prevention system, formulate epidemic prevention policies with humanistic care, actively publicize epidemic related knowledge and safeguard the rights and interests of the people.
