  • Diagnosis and Treatment of Complications after Spleen Transplantation (Report of 5 Cases)

    Objective To improve the diagnosis and treatment of complications following spleen transplantation. Methods Five cases of spleen transplantation performed to treat severe hemophilia A were analyzed retrospectively .Results Hemorrhage was found in 2 cases that one was from small vessels of spleen porta and the other one was retroperitoneal hemorrhage. Acute rejection was diagnosed in early stage to all in which it happened to 1 case within 5 days, happened to 3 cases from the fifth day to the tenth postoperative day and happened to 1 cases after the tenth day. Infection was found in 2 patientsone with incision infection and the other with infection retroperitoneal infection. All but one who died from hydrocephalus recovered as a result of timely diagnosis and treatment.Conclusion It is of great significance to the recipients with transplanted spleen that the complications are detected comprehensively and treated in time.

  • Clinical Study of Retroperitoneal Splenic Autotransplantation Combined with Lower Esophagus Transection in Treatment of Hepatic Cirrhosis Induced Portal Hypertension

    【Abstract】ObjectiveTo inquire the therapeutic effect of retroperitoneal splenic autotransplantation combined with lower esophageal transection in the treatment of hepatic cirrhosis induced portal hypertension with randomized comparasion.MethodsThe hepatic cirrhosis induced portal hypertension patients with Child A or B grade of liver function were randomly divided into splenic autotransplantation group and splenectomy group.In the splenic autotransplantation group, retroperitoneal transplantation of pedicled autosplenic tissue combined with modified lower esophageal transection was performed,while in the splenectomy group, splenectomy combined with modified lower esophageal transection was conducted.The general conduction, splenic scanning, liver function, serum tuftsin and IgM levels in patients were observed 2 to 6 months after operation, and compared with those before operation. ResultsOne patient died in the splenectomy group on the 6th postoperative day, rebleeding occurred in one case of the splenic autotransplantation group. The levels of tuftsin and IgM in splenic autotransplantation group were higher than those of splenectomy group after operation, with significant difference (P<0.01). The liver function between two groups showed no difference (Pgt;0.05).ConclusionSpleen autografts could maintain the basic immune function of spleen and survive for a long time.

  • Study on Mesenchymal Stem Cells Transplantation Through The Spleen in Treatment of Acute Liver Failure in Rat

    ObjectiveTo evaluate the therapeutic effect of transplantation of mesenchymal stem cells(MSCs) through the spleen for acute live failure in rat, and to observe migration of transplanted MSCs in vivo. MethodsOne male SD rat was sacrificed to collect MSCs, and MSCs were isolated, expanded, and purified by density gradient centrifugation combined with adhere culture method. The surface antigen expressions of MSCs in the fourth generation were detected by immunohistochemistry method. Twenty-four female rats were given D-galactosamine and tumor necrosis factor α(TNF-α) to establish models of acute liver failure, and then divided into experimental group and blank control group, each group enrolled 12 rats. MSCs of male rat were transplanted into the spleen of female acute liver failure rats in experimental group at 24 hours after model establishment, but rats of blank control group were injected saline(0.5 mL). After the MSCs transplantation, blood samples of rats in 2 groups were got to test levels of serum alanine aminotransferase (ALT), total bilirubin(TBIL), and albumin(ALB). PCR method was used to determine the expression of sex determining region Y gene(SRY gene), and HE staining was used to observe the pathological change of liver tissues of rats in 2 groups. ResultsThe MSCs of the fourth generation expressed CD44 and CD29, but didn't express CD34. There were 5(41.7%) and 3 rats(25.0%) survived at 72 hours, in 1 week and 2 weeks after MSCs transplantation in experimental group and blank control group, respectively, and the survival rate was higher in experimental group(P<0.05). The expression of SRY mRNA was detected in rats of experimental group, as well as the damage of liver tissues in rats of experimental group improved. Compared with blank control group, the levels of ALT and TBIL were lower in experimental group at all time points after MSCs transplantation(P<0.05), but in 1 week and 2 weeks after MSCs transplantation, the levels of ALB in experimental group were higher(P<0.05). ConclusionMSCs can migrate to liver tissue, settle down, and exert the function of replacing hepatocyte after it has been transplanted into the spleen.
