Objective To discuss the surgical procedures and treatment after combined liver and intestinal transplantation with portal venous drainage and enterostomy of two ends in one case.Methods A male patient with liver dysfunction and short bowel syndrome underwent the combined liver and intestinal transplantation.With the techniques of en bloc,the liver and intestinal grafts were harvested from cadaveric donor.The intestinal graft,200 cm long,was implanted with portal venous drainage and aortic inflow,and enterostomy of both ends was performed instead of intestinal anastomosis.The liver graft was placed in a piggyback fashion with end to end anastomosis of the bile ducts without T tube. Inmunosuppression protocol was administrated with campath-1H and tacrolimus.Endoscopic biopsy of intestinal graft was performed regularly,and clinical observation was done to monitor the acute rejection.Results In the first month after operation,abdominal infection was controlled by intraperitoneal drainage with open surgery.One suspect acute rejection was treated with methylprednisolone.Until sixth month,the functions of liver and intestine were progressively restored.However,the patient lost weight and could not be free from intravenous nutrition because of diarrhea.Conclusion Combined liver and intestinal transplantation with portal venous drainage and enterostomy of two ends is a simple surgical procedure with lower risk of surgical complications.This method is propitious to monitoring rejection and function improvement of the grafts.Diarrhea and loss of digestive juice are the main reasons of low body weight and malnutrition.

OBJECTIVETo study the effect of Bushen Tiaojing Recipe (BTR) and Xiaoyao Pill (XP) on cathepsin-L (Cat-L) mRNA in mice.

METHODSImmature mice were randomly divided into the normal group, the control group, the BTR group and the XP group, three in each group. Cat-L mRNA expression in mice was detected using reverse transcription polymerase chain reaction (RT-PCR) at 0, 4, 8 and 12 h after injecting 5 IU (human chorionic gonadotropin, HCG).

RESULTSCat-L mRNA expression increased gradually after HCG injection, the relative levels in the control group at 0, 4, 8 and 12 h were 0.066 +/- 0.005, 0.383 +/- 0.045, 0.737 +/- 0.024 and 1.036 +/- 0.073 respectively, comparisons between different time-points showed significant difference (P < 0.01). Compared with the control group, the Cat L mRNA expression was higher at 4 h in both BTR and XP groups (P < 0.01), at 8 h in the XP group (P < 0.05), and at 12 h in BTR group after injecting HCG (P < 0.05). Compared with the control group, cat L mRNA expression showed no statistic difference at 8 h in BTR group and at 12 h in XC group.

CONCLUSIONSBTR promoted the ovulation by enhancing the expression of CatL gene, and that of XP by advancing the peak of CatL gene expression.

OBJECTIVETo evaluate the efficacy and safety of three different spinal rotation manipulations for the treatment of lumbar disc herniation.

METHODSFrom September 2011 to April 2013,180 patients diagnosed as lumbar disc herniation were randomly divided into seat fixed rotation group (A), lateral position rotation group (B) and supine position rotation group (C) by using a digital table. Finally 10 patients were excluded and dropped, 170 patients were included in the study. There were 57 patients in group A, 57 patients in group B and 56 patients in group C. Baseline demographic characteristics of patients, clinical findings and indexes of health status had no statistically differences among three groups (P > 0.05). The manipulation was performed every other day, and the treatment duration for all patients was 3 weeks. Body pain (BP), Physical function (PF) in SF-36, Oswestry Disability Index (ODI) and adverse reactions were observed statistically 6 weeks, 3 months, 6 months, one year and two years after finishing treatment.

RESULTSBP, PF scores in 3 groups were significantly improved and ODI scores were significantly lower than those before treatment and the differences were statistically significant (P < 0.05); However, there was no significant difference among three groups in the BP, PF and ODI scores (P > 0.05). There were no obvious and serious adverse reactions among these groups.

CONCLUSIONBased on the theory of dislocation of bone joints in TCM, three kinds of spinal rotation manipulations can be used safely for the treatment of lumbar disc herniation, and the efficacy was similar.

Objective To discuss the curative effect of transplantation using donation after cardiac death (DCD) according with Chinese standard Ⅲ (C-Ⅲ).Methods The organs were obtained from 4 DCDs from 2011 to 2012,and the clinical data of DCD transplantation were retrospectively analyzed.Withdrawal of life support occurred in the operating room.Donor warm ischemia time was 7-15 min.Results The biopsy of liver was performed on the 3rd DCD.Eight cases were subjected to renal transplantations,and 3 to liver transplantations.One patient exhibited delayed graft function of the kidney from the 4th DCD.All patients made an uneventful recovery and were discharged from the hospital without rejection or surgical complication.They were followed up in outpatient department.Conclusion The use of DCD according with C-Ⅲ is an effective way to increase the number of organs available for transplantation,and can obtain satisfactory effects.

The mitochondrial enzyme glutaminase C (GAC) is highly expressed in a variety of cancer cells, resulting in increased glutamine metabolism and cancer development. Therefore, GAC has become a potential target for anti-tumor drug development. However, current GAC inhibitors shared similar structural characteristics, few new scaffolds were reported. By conducting a prokaryotic Escherichia coli expression system, human GAC protein of high-purity was obtained through lysozyme digestion combined with ultrasound dissociation, and cobalt magnetic beads purification, Moreover, we performed studies to validate interaction between small molecules and GAC protein through thermal shift assay, drug affinity responsive target stability assay, protein crosslinking and GAC enzyme activity detection. Meanwhile, a comprehensive small molecule-protein interaction confirmation and systematic pharmacodynamic study in vitro were carried out on compound C19, which was a reported GAC inhibitor screened from the Enamine database. Results showed that C19 directly bind to GAC protein, disturbed GAC tetramers formation, and inhibited its enzyme catalytic activity. By interfering GAC function, C19 dose-dependently suppressed GAC-mediated glutamine metabolism, reduced glutamate in cancer cells, and thus alleviated A549 and NCI-H1299 non-small cell lung cancer cell growth. Together, C19 was identified as a lead compound, providing a new strategy for the structural design of drugs targeting GAC.

Objective:To study the effect of immunological molecules expressive state upon the telomerase activation ( TA) of bone marrow mononuclear cells ( BMMNC ) in the hemopoietic microenvironment of patients with immune related hematocytopenia ( IRHS) ,and to explore the immunologic mechanism as well as the clinical significance of hematoclasis in marrow of IRHS patients .Methods:①TRAP-PCR-ELISA method was performed to detect the TA of BMMNC in marrow of 366 IRHS patients before and after therapy.②The molecules HLA-DR,anti-hunman IgG,FcγⅡR,mannose receptor ( MR),IL-17A and its receptor ( IL-17AR) were analysed by immunochemistry and immunofluorescence staining .③The flow cytometric ( FCM) was used to analyse the proportion of CD3+CD4+T cells as well as CD3+CD8+T cells ,CD3-CD19+B cells and CD3-CD16/56+NK cells in peripheral blood lymphocyte.60 cases of health examination were selected as the control group , and 30 cases hypoferric anemia patients were selected as disease control.The differences between patient group and control group were analysed with statistic method .Immunochemistry and immunofluo-rescence staining were performed to in situ analyze the activation-characteristics of immunocyte in bone marrow slides of IRHS ,and the dependablity of cellular immunologic injury was also checked.Results: ①The levels of TA was 0.261 7 ±0.021 6 before treatment , higher than the disease control group (0.061 6±0.031 3 ,P<0.01).Among of them HLA-B27+patients were higher than HLA-B27-patients (0.301 3±0.020 6 vs.0.192 3±0.012 9,P<0.05).Serious IRP patients with HLA-B27+IgG+were obviously higher than HLA-B27-IgG+patients (0.401 6±0.017 2 vs.0.221 1±0.011 0,P<0.01).②In marrow of HLA-B27+IgG+patients,both cell immunity and humoral immunity were in disorder in the hemopoietic microenvironment ,and immonocyte in marrow expressed HLA-DR, FcγⅡR,IL-17A,IL-17RA and MR,and Th,Ts,B cell and NK cell in peripheral blood increased in different degree ,inducing the in-flammation of haemocyte and lead to destruction.③Humoral immunity was in the dominant level in morrow;humoral immunity of HLA-B27-IgG+patients,immonocyte expressed FcγⅡR in high level,but IL-17A was seldom expressed,only CD19+B cell was increased slightly ,the antibody dependent cellular cytotoxicity ( ADCC) was the main mode of destruction.After therapy glucocorticoids associated with ciclosporin A ,the TA level of BMMNC decreased to 0 with devitalization.Conclusion: The telomerase activation of bone marrow mononuclear cells in IRHS is related with the immune state of hemopoietic microenvironment and the pathologic lesion degree of hema -topoietic cell in marrow.It is viral infection and immunological activation as well as a variety of inflammatory factors play a part in the immunologic injury that might be an important factor of the enhancement in TA.

Background and purpose:Ionizing radiation(IR) activates the early growth response- I(Egr1) promoter through specific cis-acting sequences termed CArG elements by production of radical oxygen intermediates(ROls).Egr-EG,an expression vector pCIneo containing CArG elements cloned upstream of the cDNA for human recombinant GM-CSF,was used to treat hematopoietic damage due to chemotherapy.Commonly used chemotherapeutic agents can cause tumor cell death by producing DNA damage and generating ROIs.We therefore hypothesized that clinically employed chemotherapeutic agents that increase ROIs could also be employed to activate Egr-EG in a chemoinducible gene therapy strategy.This study was done to explore the chemo-protective effect of the expression of hematopoietic growth factors regulated by Egr-1 promoter on chemotherapy induced damage. Methods:The human GM-CSF cDNA and EGFP cDNA were linked together with internal ribosome entry site(IRES) and then inserted into the eukaryotic expression vector pCI-neo with the Egr-1 promoter(Egr-EG),and was further transduced into human bone marrow stromai cell lines HFCL(HFCL/EG).The HFCL/EG cells were transplanted i.v.into BI6 melanoma in C.B-17 combined immunodeficient(SCID) mice.5-FU was given i.p.on day 3 and 4.The white blood cell amount in peripheral blood,the expression of EGFP and GM-CSF in human stromal cell engrafted in recipient mice were detected by flow cytometry,RT-PCR,Western blot and colony-forming units for granulocytes and macrophages(CFU-GM),respectively.Results:In contrast to the two control groups,HFCL/EG(the Egr-regulatory element-derived expression of GM-CSF gene therapy) resulted in a proportional increase in the number of the white blood cell after chemotherapy,no significant diifferences were found for CFU-GM in bone marrow cells and the inhibition ratio on tumor in recipient mice.Chemotherapy could markedly increase the expression of EGFP and GM- CSF mRNA/protein as compared with that of non-chemotherapy control groups and HFCL group.Conclusion: Chemoinducible GM-CSF gene therapy regulated by Egr-1 promoter can ameliorate the toxic effect on 5-FU chemotherapy-inducible hematopoietic damage.
