Objective To analyze and evaluate the efficay of split liver transplantation in children.Method From September 2006 to December 2014,210 children were treated with liver transplantation in Tianjin First Central Hospital.The clinical data were retrospectively analyzed and the difference in postoperative survival was compared between the groups.The 210 childrens were categorized into living donor liver transplantation group (183 cases) and split liver transplantation group (27 cases) based on their operation styles.In living group,all donors to recipients were immediate relatives within three generations.In split group,all donors were men,and livers were obtained from no heartbeat donors.Postoperatively,tacrolimus combined a duplex of prednisolone served as immunosuppression scheme.The survival and incidence of complications were observed.Result There was significant difference in the sex ratio between two groups (P＜0.05).The donor liver cold ischemia time was significantly longer in split group than in living group (P＜0.05).The 1-month,6-month,1-year and 2-year overall survival rate in 210 recipients was 99.5％,98.1％,96.2％ and 94.2％ respectively.The median follow-up time in living group and split group was 15.2months and 26.1 months,respectively.The 1-mont,6-month,1-year and 2-year survival rate was 99.5％,96.7％,92.6％ and 74.1 ％ in living group,and 97.8％,96.2％,77.8％ and 74.0％ in split group,respectively (P＜0.05).During the follow-up period,8 cases died (29.6％) in split group (5deaths due to infection and sepsis,and 3 deaths due to multiple organ failure),and 10 cases died (5.5％) in living group (6 deaths due to infection and sepsis,and 4 deaths due to multiple organ failure).Conclusion In the case of strict selection of donors,split liver transplantation can obtain good effect,but the incidence of complications is higher than living donor liver transplantation.Especially,the biliary complications should be prevented and managed actively.

Atractylodis Macrocephalae Rhizoma and Atractylodis Rhizoma were widely used in strengthening spleen under different disease conditions, and were easily and often misused each other. Therefore, DNA barcode was used to distinguish Atractylodis Macrocephalae Rhizoma and Atractylodis Rhizoma from their adulterants to ensure the safe use. The sequence lengths of ITS2 of Atractylodes macrocephala, Atractylodis Rhizoma (A. lancea, A. japonica and A. coreana) were both 229 bp. Among the ITS2 sequences of A. macrocephala, only one G/C transversion was detected at site 98, and the average GC content was 69.42%. No variable site was detected in the ITS2 sequences of A. lancea. The maximum K2P intraspecific genetic distances of both A. japonica and A. coreana were 0.013. The maximum K2P intraspecific genetic distances of A. macrocephala, A. lancea, A. japonica and A. coreana were less than the minimum interspecific genetic distance of adulterants. The ITS2 sequences in each of these polytypic species were separated into pairs of divergent clusters in the NJ tree. DNA barcoding could be used as a fast and accurate identification method to distinguish Atractylodis Macrocephalae Rhizoma, Atractylodis Rhizoma, from their adulterants to ensure its safe use.
