Objective To analyze the protection supplied by HSCs in vivo after islet cells homotransplantation. Method Diabetic mice were randomly divided into three groups as diabetic group,islet-transplant group and co-transplant group. 300 islets alone or mixed with HSCs were transplanted under the capsule of the kidney of the diabetic recipients respectively. Blood glucose and the length of normal blood glucose level were recorded and we collected the blood and tissue of islet graft 7 days after transplantation in each group. Blood concentration of TGF-β, TNF-α, IL-1β and IFN-γ were detected by ELISA. The infiltration of lymphocytes was observed by HE staining and immunohistochemieal examination.Result Co-transplant group had a prolonged islet allograft survival for (23.75 ± 8. 96) days, compared with the islet alone of (11.9 ± 6. 92) days. Blood concentration of TGF-β in co-transplant group was (2292.31 ± 5.87) pg/ml, significantly higher than those in simple transplant group (1246.55 ±38.91) pg/ml(P <0.05), there was no differentence in the two groups for TNF-α,IL-1β and IFN-γ.Conclusion HSCs may prolong the islet graft survival by expressing higher level of TGF-β and form a capsule around the graft.

OBJECTIVETo perform a meta-analysis on clinical outcomes of minimally invasive percutaneous plate osteosynthesis (MIPPO) or open reduction and internal fixation (ORIF) for distal tibial fractures in adults.
METHODSPubmed database (from 1968 to March 2014), Cochrane library and CNKI database (from 1998 to March 2014) were searched. Case-control study on minimally invasive percutaneous plate osteosynthesis (MIPPO) or open reduction and internal fixation (ORIF) for distal tibial fractures in adults were chosen,and postoperative infection, operative time, blood loss, fracture nonunion rate, delayed union,fracture malunion rate were seen as evaluation index for meta analysis. The system review was performed using the method recommended by the Cochrane Collaboration.
RESULTSTotally 5 studies (366 patients) were enrolled. Meta-analysis showed that there were significant meaning in postoperative infection between MIPPO and ORIF [OR = 0.23,95% CI (0.06,0.92), P = 0.04]; fracture nonunion rate in MIPPO was lower than in ORIF group [OR = 0.16, 95% CI (0.03,0.76), P = 0.02]; operative time in MIPPO was shorter than in ORIF group, and had significant difference [MD = -14.42, 95% CI (-27.79, -1.05), P < 0.05]; blood loss in MIPPO was less than in ORIF group [MD= -87.17,95%CI (-99.20, -75.15), P < 0.05]; there was no obviously meaning in delayed union between two groups.
CONCLUSIONFor distal tibial fractures in adults, MIPPO has, advantages of short operative time, less blood loss, lower incidence of infection and fracture non-uniom, but with high fracture malunion rate. MIPPO for distal tibial fractures in adults is better than ORIF, and the best treatment should choose according to patient's condition.
