Résumé
Objective To investigate the detection value of the positive rate of MP-IgM in children with Henoch-Schonlein purpura (HSP).Methods 80 HSP patients were chosen as the research subjects (the observation group),the other 40 healthy children were chosen as research subjects(the control group).The positive rate of MP-IgM,and positive changes in immune function of children with HSP combined with MP-IgM were analyzed in two groups.Results 32 cases were MP-IgM positive in the observation group,the positive rate was 40％.The MP-IgM positive rate in the observation group was significantly higher than that in the control group(P ＜0.05).The percentage of CD4+ in the observation group was significantly lower than that in the control group,the percentage of CD8+ was significantly higher than that in the control group,CD4+/CD8+ was significantly lower than that in the control group,NK was significantly lower than that in the control group(P ＜0.05).The percentage of CD8+ in MP-IgM positive group was significantly higher than that in the negative group,the percentage of CD4+/CD8+ was significantly lower than that in the negative group,the percentage of NK was significantly lower than that in the negative group (P ＜ 0.05).Conclusion MP infection is an important cause of HSP,it can aggravate the immune dysfunction and play an important role in the occurrence and development of HSP.
Résumé
Cervical anastomosis by the thoracic approach for the treatment of upper esophageal cancer can simplify surgical steps and reduce incidence of anastomotic leak. This approach has been used for 26 patients with upper esophageal cancer who were admitted to the Jiangsu Cancer Hospital from July 2006 to August 2009. The mean length between lesion and incisor was 23.3 cm. General anesthesia and double-lumen intubation through left posterolateral incision in the fifth intercostal space was adopted. The stomach was dissociated with the technique of "in situ dissociation", and esophagus was dissociated conventionally. Double purse-string suture was adopted to fix the esophageal mucosa onto the supportive base of the stapler, and make purse-string suture to fix stomach on the center pole of the stapler. There was one failure case which has been converted to the manual cervical anastomosis, and the operations for the rest 25 cases were completed successfully, without anastomotic leakage and positive margin. The average blood loss was (352 ±211 )ml, and the average operation time was (3.7 ±0.6 )hours.
