Objective To investigate injecting recombinant human granulocyte-colony stimulating factor(rhG-CSF) on the proportion of peripheral neutrophilic granulocyte and their surface molecules expression in healthy people.Methods The peripheral blood samples were collected from the healthy people who were injected with rhG-CSF.The expressions of CD62L,CD11a,CD44 and CD49d on the surface neutrophilic granulocytes were determined before and after injection with flow cytometery.Results The median percentage of neutrophilic granulocytes in peripheral blood leucocytes after injecting rhG-CSF significantly increased from 60% to 85%(P0.10).Conclusion Injecting rhG-CSF may obviously impact the expression of CD62L and CD49d on neutrophilic granulocytes.

Objective To investigate the metabolic differences of Tacrolimus in different transplant recipients. Methods A retrospective study was conducted, 30 patients of the organ transplant admitted to organ transplantation center of General Hospital of Chinese People's Armed Police Forces from January 2002 to August 2012 were enrolled, and they were divided into combined liver and kidney transplant (SLK) group, single liver transplant group and single renal transplant group, 10 cases in each group. The SLK group and the simple liver transplantation group were given the same drug regimen, methylprednisolone injection was given during operation, and tacrolimus+ mycophenolate mofetil+ prednisone triple immunosuppressive therapy was taken after operation, on the first day after operation, the initial dose of tacrolimus was given 0.06 mg·kg-1·d-1 divided into 2 times taken orally, and on the third day after operation, the concentration of tacrolimus was detected; after operation group for 2 - 4 days, single renal transplantation group was given tacrolimus the initial dose of tacrolimus 0.15 mg·kg-1·d-1 was divided into 2 parts for twice oral administration, after 2 - 3 days of the above treatment, monitoring the concentration of tacrolimus began. One month after transplantation, the metabolic differences of tacrolimus among the three groups were compared.Results One month after operation, the oral tacrolimus doses (μg·kg-1·d-1: 74.78±32.65 vs. 80.62±24.02, 85.58±16.78) and the monitored blood drug concentration (μg/L: 6.64±2.73 vs. 7.50±3.08, 7.46±3.20) in SLK group were lower than either the single liver transplantation group or single renal transplantation group, but the comparisons among the three groups, there were no statistically significant differences(allP > 0.05).Conclusions In SLK group, the protective effect of transplanted liver on transplanted kidney may be related to the length of postoperative time. Liver transplantation performed within post-operative one month has no protective effect on the transplanted kidney.

Objective To study the effect of Golgi protein 73(GP73) on inflammation, and to reveal the effect of GP73 on tumorigenesis and metastasis.Methods The transcriptional activity of NF-κB and the expression of IL-1β, IL-6 and TNF-αwith GP73 overexpression or knockdown were detected to illuminate the role of GP73 in inflammation.According to the TCGA database, the correlation between the transcriptional activity of GP73 and the expression of NF-κB, IL-1β, IL-6 and TNF-αwas analyzed to determine the role of GP73 in tumor inflammation.Results Correlative analysis showed that there was a positive correlation between the expression of GP73 with NF-κB, IL-1β, IL-6 and TNF-α.The transcriptional activity of NF-κB was upregulated by GP73 overexpression, but downregulated by GP73 knockdown.The expression of IL-1β, IL-6 and TNF-αwas upregulated by GP73 overexpression.Ammonium pyrrolidinedithiocarbamate ( PDTC ) was in-volved in inflammation reaction induced by GP73.Conclusion GP73 is possibly involved in inflammation and promotes tu-morigenesis and metastasis.

Objective To evaluate the function of MRE11 in inflammasome activation.Methods Different stimuli,in-cluding Poly(I∶C), Poly(dA∶dT),E.coli gDNA,293T gDNA,CPPD and HSV,were used to identify the effective inflamma-some activator using ELISA.Then, MRE11 siRNA oligos were sythesized and transfected into THP-1 cells while Western blotting was used to analyze the efficacy of MRE 11 knockdown .Finally ELISA and Western blotting were used to analyze the involvement of MRE11 in inflammasome activation induced by Poly (I∶C), Poly(dA∶dT), E.coli gDNA and 293T gDNA. Results The IL-1βsecretion and pro-caspase-1 activation which induced by Poly ( I∶C) , Poly( dA∶dT) , E.coli gDNA and 293T gDNA were reduced with different degrees in MRE 11-knockdown THP-1 cells.Conclusion These results indicate that MRE11 is required for inflammasome activation induced by genetic materials .

BACKGROUNDTo investigate the method and therapeutic efficacy of artificial liver support system (ALSS) in treatment of severe viral hepatitis.
METHODSA total of 83 patients including 66 with severe viral hepatitis were treated with ALSS using Baxter-550 artificial kidney and Biologic-DT system.
RESULTSThe levels of mean bilirubin, ALT, AST, BUN, Cr and endotoxin was significantly decreased after the treatment. Of the 66 patients?with severe viral hepatitis, 31(47.0%) had improvement in symptoms and 35 (53.0%) died or left hospital. In the control group,50(27.6%) out of the 181 had improvement in symptoms and 131(72.4%) died or left hospital.
CONCLUSIONSALSS could exert certain therapeutic effects on severe viral hepatitis.
