ObjectiveTo explore the therapeutic efficacy of artificial dermal in repairing depth of burn wounds.MethodsTwenty-two cases of patients with depth bum who were admitted to our hospital during August of 2008 to August of 2010 were enrolled in this trial for retrospective study.The style of management was evaluated in these patients.Burn wound depth and severity was assessed immediately after patients admission,wound treatment was performed after patients with stable vital signs and wound edema peak period vanished.Artificial dermal was grafted onto the wound tissue after the primary debridement. Then,transplantation of artificial dermal was performed,with moist dressingonto it.After two weeks,the razor thick autoskin was grafted onto the surface of the artificial dermal after the removing of its silicon membrane during the secondary operation.ResultsThe wound healed completely with the survival of skin grafting and satisfactory appearance in all 22 patients. Furthermore,the scar in the donor site exhibited unconspicuous. Conclusion It's an optimal choice to repair deep burn with artificial dermal and thick autoskin.

Objective To retrospectively review and compare the clinical results of allogeneic peripheral blood stem cell transplantation (allo-PBSCT) from HLA- matched sibling donors mobilized with different regimens. Methods Seventy-one patients with hematological malignant diseases received allo-PBSCT from HLA-matched sibling donors in our department. Among them, 24 received allografts mobilized with G-CSF (group G), and the remaining (47 cases) were mobilized with G-CSF and GM-CSF (group G+ M). CD34+ subsets and T cell subsets in the allografts were analyzed, and the time of hematopoietic reconstitution and the incidence of graft versus host diseases (GVHD) were compared. The adverse effects on the donors after mobilization were also observed. Results The enough targeted CD34+ cells in all donors were harvested by 1-3 aphereses. Ninety-six h after mobilization, WBC counts of the donors were significantly higher in group G than in group G + M [(49. 6± 19. 5) 109/L vs (25.4 ± 10. 4) 109/L, P＜0. 05]. Analysis of the CD34+ subsets showed that the percentage of cells with the CD34+/CD38- phenotype was significantly higher in group G + M than in group G [(37. 7 ± 5. 7) % vs (31.4 ± 4. 5) %, P＜0. 05]. There was no significant difference in T cells and subsets of grafts. There was no significant difference in the number of total CD34+ cells and CD34+ CD38- cells, and infusion of T cells between two groups. The days required for the recovery of neutrophils and platelets was inversely correlated with the infused CD34+ and CD34+ /CD38- cell number. There was no significant difference in incidence of acute and chronic GVHD between two recipient groups. Seventeen cases and 10 eases among 71 eases died of relapses of primarydiseases, and complications of transplantation such as severe GVHD and infections respectively.Fourteen cases in group G (58.3 %) and 31 cases in group G+ M (66.0 %) survived. The most common adverse events in the donors were bone pain and fever, which mostly occurred 36 h after mobilization and could be relieved by non-steroidal anti-inflammatory drugs. Conclusion Two mobilization regimens showed equivalent clinical results. But the combined regimen of G-CSF and GM-CSF demonstrated a significantly greater mobilization of cells with the CD34+/CD38- phenotype.Meanwhile in allogeneic PBSCT, a greater number of total CD34+ cells and CD34+ CD38- cells infused may be associated with faster hematopoietic reconstitution of recipients.

Objective To investigate the effect of protein phosphatase 5 (PP5) on lipid metabolism in the PP5 knockout (KO) mice.Methods Male PP5 KO and wild type (WT) mice at the age of 6 weeks were used in this study. In order to study the effect of high fat diet ( HFD) feeding, the body weight was measured.The liver histology was examined by HE and oil red O staining.To further verify PP5 functions in the adipogenesis, in vitro experiment was carried out using mouse embryonic fibroblasts (MEF).Western blotting and real-time PCR were performed to quantified the expression of lipid metabolism-related genes in the liver tissues.Results Compared with the WT mice, the body weight gain was slower in the KO mice.The size of the lipid droplets was smaller and the quantity was less in the KO mouse liver tissue.In vitro study revealed that the KO mouse MEF cells showed less differentiated adipocytes with smaller lipid droplets than the WT MEF cells.This observation was further confirmed by detecting the expression of adipogenesis-related genes in the HFD liver.The markers of adipocyte differentiation, such as CD36, AP2, PPARγ2, and Glut4, were significantly decreased, while energy expenditure-related markers, such as phosphorylation of GR and expression of UCP1, were significantly increased.Conclusions Protein phosphatase 5 may play a regulatory role in the mouse lipid metabolism through regulating the de-phosphorylation of p-GR and enhancing the expression of UCP1.

Objective To investigate the regulatory effects of probiotics on ghrelin and their pro-tective effects on pulmonary function of children during acute lung injury.Methods Fifty children with acute lung injury were recruited form Henan Provincial People′s Hospital during 2010 to 2013 and randomly divided into two groups.In addition to regular therapy, those who received probiotics treatment were set up as the probiotics treatment group and the others were considered as the control group.Levels of ghrelin, sur-factant protein A( SP-A) , TNF-αand IL-6 in serum samples were measured before and 10 days after the cor-responding treatments.Each patient was analyzed by pulmonary function test and echocardiography.The vol-ume to peak expiratory flow ( VPEF) , ratio of time to reach peak tidal expiratory flow to total expiratory time ( TPTEF/TE) , mean arterial pressure ( MAP) and pulmonary artery pressure ( PAP) were recorded for sta-tistical analysis.Results The levels of SP-A, TNF-αand IL-6 in serum samples from the probiotics treat-ment group were decreased on day 10 as compared with those of the control group [(195.9±54.3) ng/ml vs (245.5±56.4) ng/ml, (382.0±56.4) pg/ml vs (440.7±46.8) pg/ml, (221.5±62.6) pg/ml vs (303.5 ±83.9) pg/ml;P<0.05] .Children from the probiotics treatment group showed higher values of VPEF and TPTEF/TE on day 10 as compared with those without probiotics treatment [(25.3±4.5) ml vs (23.8±4.6) ml, (29.5±4.3) %vs (26.8±4.7) %;P<0.05].Treatment of children with probiotics increased MAP and decreased PAP [(74.5±6.7) mmHg vs (71.9±6.9) mmHg, (25.5±6.4) mmHg vs (29.1±6.2) mmHg] .The levels of ghrelin in patients received probiotics treatment were higher than those of children without probiotics treatment [(329.3 ±49.6) pg/ml vs (296.6 ±48.5) pg/ml].The levels of ghrelin showed negative correlations with the levels of SP-A, TNF-α, IL-6 and PAP on day 10, but positive correla-tions with TPTEF/TE and MAP (P<0.05).Conclusion Use of probiotics to children with acute lung inju-ry could regulate the level of ghrelin, alleviate the inflammation of lungs and improve the recovery of lung function and circulation.Therefore, probiotics treatment had positive effects on the protection of pulmonary function.
