Objective To study the prevention and cure effect of immunoregulation therapy on postoperative infectious complications of calculous obstructive jaundice.Methods Prospective,randomized,blind and controlled clinical analysis of 40 patients conforming to the standard of calculous obstructive jaundice was carried out.The patients were divided into two groups at random.One was control group (n=20) with regular therapy,and the treatment group (n=20) with ulinastatin plus thymosin-α1 on the base of regular therapy for 1 week.The immunological indexes were determined before and after therapy on the 1st,3rd,5th、7th and 14th day,including the changes in lymphocyte count,CD14+ monocytes human leukocyte antigen (locus) DR (HLA-DR),and the incidence of postoperative infection were observed.Results The incidence of postoperative infectious complications in treatment group (10％) was remarkable lower than that in control group (30％,P＜0.01).There was significant difference between two groups (P＜0.05).After the 3rd,up to 14th day of therapy,the counts of lymphocyte and CD14+ monocytes HLA-DR were significantly higher than those in control group (all P＜0.05).Conclusions Immunoregulation therapy can improve the prognosis of obstructive jaundice patients in a period of 14 days of observation,and lymphocyte counts and CD14+monocytes HLA-DR were increased significantly,showing that immuno suppression can be ameliorated.Immunoregulation therapy could effectively prevent infectious complications of calculous obstructive jaundice.

Extracorporeal membrane oxygenation(ECMO) is a type of technique which can be used to replace patients' pulmonary function and cardiac function effectively. Since 2000s,the technique began to apply in pediatric patients but still developed very slowly. As well,patients transport with ECMO is another problem for the pediatricians. So,it is necessary to raise the conception of pediatric ECMO transport network and construction of the network. In this paper,the concept of pediatric ECMO transport network,current status of transport,the characteristics and constitution of pediatric ECMO transport network,indication for transport of pediatric ECMO,the problems in the construction of network were introduced to promote the construction of the network.
