compared with the after-modeling status,the recovery of intestinal mucosa villi and recess structure was not obvious,and the inflammatory cell infiltration in the lamina propria persisted in the control group.Conclusion Gln repairs ischemia-reperfusion injury in the intestinal mucosa by regulating intestinal mucosa inflammatory cytokine release,inhibitng inflammatory response,and reducing the permeability of the intestinal mucosa.

Objective To evaluate the role of heme oxygenase-1 ( HO- 1 ) in inflanmatory responses in septic rats.Methods Seventy-two male Wistar rats,aged 10-14 weeks,weighing 250-300 g,were used in this study.The animals were anesthetized with intraperitoneal 2% pentobarbital sodium 50 mg/kg.Sepsis was induced by cecal ligation and puncture (CLP).The animals were randomly divided into 4 groups ( n =18 each):control group (C group),CLP group,HO-1 inducer cobalt protoporphyrin Ⅸ (CoPPⅨ) group (Co group) and HO-1 inhibitor zinc protoporphyrin Ⅸ (ZnPPⅨ) group (Zn group).Six rats in each group were randomly chosen at 6,12 and 24 h after operation to collect blood samples,and then the animals were sacrificed to obtain lung tissues at 24 h after operation.The serum levels of TNF-α,IL-6 and high mobility group box 1 (HMGB1) were determined by ELISA.The expression of HMGB1 mRNA in lung tissues was detected by RT-PCR.Another 40 Wistar rats with the same conditions were grouped according to the method mentioned above and the survival curve was drawn.Results Compared with group C,the serum levels of TNF-α,IL-6 and HMGB1 were significantly increased,the expression of HMGB1 mRNA in lung tissues was up-regulated,and the survival rate was significantly decreased in CLP,Co and Zn groups ( P <0.05).Compared with group CLP,the serum levels of TNF-α,IL-6 and HMGB1 were significantly decreased,the expression of HMGB1 mRNA in lung tissues was down-regulated,and the survival rate was significantly increased in group Co ( P < 0.05),while no significant change was found in the parameters mentioned above in group Zn ( P > 0.05).Conclusion Inducing the expression of HO-1 is helpful in reducing inflammatory responses in septic rats.

Objective In previous study,we carried out refined mapping of loss of heterzygosity (LOH) on 1q31.1-32.1 and found that a minimal region of frequent deletion was located at DIS413-D1S2622,which indicated that the region could harbor a tumor suppressor gene associated with colorectal carcinoma.This study was to screen for the potential tumor suppressor gene (TSG) on D1S413-D1S2622 in Chinese origin patients with sporadic colorectal cancer.Methods 25 genes located in the D1S413-D1S2622 region were chosen and a microarray-based high throughput screening conducted in 19 sporadic colorectal cancers to identify candidate tumor suppressor genes.The relationship between expression levels of candidate genes and the clinicopathological data was analyzed.Real-time PCR was performed to validate the microarray results.Results According to the microarray-based high throughput screening,we found 4 significantly down-expressed genes,including CSRP1,LMOD1,PPP1R12B and CFHL3.There was no significant association between of CFHL3,CSRP1,LMOD1,PPP1R12B expression and the clinicopathological data.CSRP1 could be a colorectal cancer related tumor suppressor gene.CSRP1 was down-regulated in colorectal cancer.Conclusions CSRP1 might be involved in the progression of colorectal cancer.

The fine structure of enoxaparin sodium samples with different degree of 1,6-anhydro derivatives were analyzed with polyacrylamide gel electrophoresis, high performance liquid chromatography, ultraviolet spectroscopy, infrared spectroscopy and nuclear magnetic resonance spectroscopy. A further study of anticoagulation activity of enoxaparins was performed, including those on their inhibition activities of coagulation factor Xa (FXa) and thrombin (FIIa). The results showed that the anti-FXa and -FIIa activities of enoxaparins with different degree of 1,6-anhydro derivatives (20.0%-39.7%) with similar structure characteristics, had decreasing tendency when the degree of 1,6-anhydro derivatives increased. Especially, the anti-FXa activity was sensitive to the change of the degree of 1,6-anhydro derivatives.

ObjectiveTo investigate the variation of peripheral blood CD34+ cells during the hematopoietic stem cell mobilization,and its influence on the collecting timing and results.Methods Twenty-seven cases of peripheral blood hematopoietic stem cell mobilization and collection from April 2010 to December 2011 were analyzed,including 13 autologous cases mobilized with chemotherapy combined with granulocyte colony-stimulating factor (G-CSF,10 μg· kg-1 · d-1) and 14 cases of healthy donors mobilized with only G-SCF (7.5 μg · kg- 1 · d- 1 ).The number of peripheral blood CD34+ cells was counted,and its correlation with the yield of mononuclear cells (MNCs) and CD34+cells was analyzed.ResultsMNCs (5.84 ± 1.48) × 108/kg and CD34+ cells (3.93 ± 2.16) × 106/kg were obtained in healthy donors,and (6.58 ± 3.72) × 108/kg MNCs and (3.98 ± 3.06) × 106/kg CD34+ cells were obtained in autologous cases,respectively.There was only 1 failure in autologous cases.The peak of peripheral blood CD34+ cells in autologous cases appeared at day 4 after the treatment of G-CSF,and in healthy donors the number of peripheral blood CD34+ cells at day 5 was still in ascendant phase.The CD34+ cells/kg in the collection products were positively correlated with the percentage and absolute value of peripheral blood CD34+ cells.The cases ratio of CD34+ cells≥2× 106/kg in the products of single collection was up to 76.2% (16/21) in the cases with peripheral blood CD34+ cells absolute value greater than 20/μl.ConclusionThe number of peripheral blood CD34+ cells was an important monitoring indicator in hematopoietic stem cell mobilization and collection,CD34+ cell absolute value ≥20/μl could be used as collection threshold.

Objective To explore the long-term outcomes and complications of patients with hematological malignancies (HM) after haploidentical donor transplantation (HDT) or siblingidentical donor transplantation (SDT).Methods From June,2011 to July,2016,89 patients with HM receiving allo-HSCT were retrospectively analyzed,including 57 patients undergoing HDT and 32 cases undergoing SDT.Results The median time to achieve neutrophil engraftment was 2 days shorter after HDT than SDT,whereas that of platelet engraftment was 3 days longer after HDT than SDT.The cumulative incidence for 3 to 4 grade acute graft-versus-host disease (GVHD) was not obviously different between HDT and SDT (8.77% versus 12.5% respectively;x2 =0.313,P =0.576).The cumulative incidence for chronic GVHD was not significantly different between HDT and SDT (45.6% versus 37.5%;~ =0.551,P =0.458).Cytomegalovirus (CMV) reactivity was significantly higher in patients after HDT (77.19%) than those after SDT (21.88%) (x2 =25.633,P<0.001).The occurrence of hemorrhagic cystitis was also obviously higher in patients after HDT (26.32%)than those after SDT (3.85%) (x2 =5.340,P =0.021).The 1-,2-,and 3-year relapse-free survival rate of patients receiving HDT and SDT was 63.9%,55.4%,44.3% and 71.2%,58.3%,51.8%,respectively (P =0.541).The 1-,2-,and 3-year overall survival rate of patients receiving HDT and SDT was 75.3%,65.3%,52.3% and 76.9%,62.9%,62.9%,respectively (P =0.777).Conclusion Considering similar incidence of severe GVHD and long-term outcomes,haploidentical donors should be recommended as a potential alternative donor source when an identical donor is lacking for patients with HM.

Objective:
To investigate the effect of Meek skin grafting on patients with extensive deep burn at different age groups.
Methods:
Eighty-four patients with extensive deep burns conforming to the study criteria were hospitalized in our unit from April 2011 to April 2015. Patients were divided into children group (C, with age less than 12 years old), young and middle-aged group (YM, with age more than 18 years and less than 50 years old), and old age group (O, with age more than 55 years old) according to age, with 28 patients in each group. All patients received Meek skin grafting treatment. The use of autologous skin area, operation time, wound healing time, and hospitalization time were recorded. The survival rate of skin graft on post operation day 7, complete wound healing rate in post treatment week 2, and the mortality were calculated. Data were processed with one-way analysis of variance,
