Objective To discuss the etiological factor,clinical situation,diagnosis and therapy of early postoperative inflammatory small bowel obstruction.Methods The clinical data of fifty cases with early postoperative inflammatory small bowel obstruction were analyzed retrospectively.Results 44 cases were cured in a mean period of 10.3 days with non-operative therapy.Six cases received operation including 4 cases enterolysis and 2 cases section intestinal resection.Infection of incisional wound occurred in 2 case and long time diarrhoea and malnutrition occurred in 2 case.Conclusion Early postoperative inflammatory small bowel obstruction mainly occurs in about 1-2 weeks after operation and is related to extensive operation and insult.Early postoperative inflammatory small bowel obstruction has typical signs and symptoms of bowel obstrurtion.If conservative therapy isnt effective or strangulation of bowel occurs,operation should be adopted and operation style should be simple and effective.

To investigate the role of ligustrazine on relaxation of the isolated rabbit corpus cavernosum tissue in vitro, the effects of ligustrazine on the corpus cavernosum were observed by using experimental method of smooth muscle strips. Concentration-responses to phenylephine (PE) and KCl were recorded. The results showed that ligustrazine concentration-dependently depressed the contraction response of smooth muscle strips induced by PE. The maximum percentage relaxation of cavernosal strips by ligustrazine was 74.1% ±6.2 % (compared with control: 21.9 % ±5.6 %, P ＜0.01). Ligustrazine concentration-dependently reduced the amplitude of the contraction induced by cumulative doses of PE or KCl, shifted the cumulative concentration response curves of PE and KCl to the right and depressed their maximal responses. It was concluded that ligustrazine could significantly relax the cavernosal muscle contraction induced by PE in vitro. The results suggested that ligustrazine inhibited calcium ion influx.
