This paper explores the reasonable construction of disease settlement standard system based on production process and source of costs, charging standards and the quantitative relationship between disease and settlement, putting forward clinical path minimum settlement standard and regulate a major guideline for settlement standard for local diseases by excluding the excessive service from patient's wills, high value consumables and high-priced drugs based on clinical path cost variation coefficient measured by disease typing and actual cost variation coefficient determined by class of hospital.

To study the expression of transforming growth factor β1 (TGFβ1) and platelet-derived growth factor (PDGF) in alveolar type Ⅱ cells and their significance in the process of pulmonary fibrosis. MethodsCultivation of alveolar type Ⅱ cells were mode from normal adult rat and of silicotic animal model of rat was established. In situ hybridization and irnmunohistochemieal staining were applied to detect the gene expression of TGFβ1 and PDGF-B in the alveolar type Ⅱ cells of primary culture and silicotic tissue. Results(1) In situ hybridization and immunohistochemical staining showed the positive expression of TGFβi, PDGF-B rnRNAs and their relevant proteins in cultured alveolar type Ⅱ cells. (2) The positive expression of TGFβ1, PDGF-B rnRNAs and their proteins were prominent in the proliferative alveolar type Ⅱ cells of experimental group of silicotic models. Weak expression of TGFβ1 mRNA were found only in a part of normal alveolar type Ⅱ cells of control group. ConclusionThe proliferative alveolar type Ⅱ cells express TGFβ1 and PDGF-B, which may play an important role in silicotic fibrcsis.

Objective To observe the effect of bortezomib on acute graft-versus-host disease (aGVHD) in an aGVHD model of mice and investigate the related mechanism. Methods Male C57BL/6( H-2Kb)mice were used as donors and female Balb/c (H-2Kd) mice used as recipients. Balb/c mice received total body irradiation (TBI) by 7.0 Gy X-radiation, and randomly divided into five groups. normal (group A), TBI (group B), TBI + bortezomib (group C), TBI + bone marrow cells (BMC) + spleen cells (SC) (group D) and TBI + bortezomib + BMC + SC (group E). The physical signs and the pathological damage of aGVHD, mean survival time, and chimerism were observed in recipients. The NF-κB p65 levels in nuclei of the liver and small intestine tissues of groups A,B and C were analyzed by Western blot. Results ( 1 ) The clinical aGVHD score in group D was (7.37±0. 32), significantly higher than in group E (5.85 ± 0.40) (P＜0. 05). Histopathology of the gut, liver and skin illuminated that the Ⅲ-Ⅳ degree GVHD occurred in group D. The occurrence of aGVHD in group E was later than in group D. The symptoms and the pathological damage of aGVHD in group E were milder than in group D. The average survival time in group E was significantly longer than that in group D (P＜0.05). The percentage of donor-derived cells in recipient mice was above 90% at day 12 after transplantation; (2) NF-κB p65 levels in nuclei of the liver and small intestine tissues in group B was significantly higher than in group C on the day 1,3 and 5 (P＜0. 05). Conclusion Bortezomib can inhibit the activation and expression of NF-κB,which may be the underlying mechanism for it to relieve aGVHD.

Objective To observe the therapeutic efficacy of 6% hydroxyethyl starch 130/0.4 (trade name: voluven) and polygeline on dog with hemorrhagic shock and their effect on immune function of red blood cells (RBC). Methods Eighteen dogs were randomized into three groups (n=6 in each group): normal sodium group, voluven group and polygeline group. Hemorrhagic shock models were set up according to Wiggers’ method. The mean arterial pressure value was bled to (45.56?3.69) mmHg within 10 min and maintained at this level for 60 min. Subsequently the dogs were resuscitated with normal saline or voluven or polygeline. The hemodynamics were measured before and 60 min after shock and 10, 30 and 60 min after infusion. The concentrations of MDA in plasm, C3b receptor garland rate (RBC-C3bRR) and RBC immune complexes garland rate (RBC-ICR) were measured. Results At 60 min after shock, MAP and CO were significantly lower than these before shock (P

OBJECTIVE To study the carbapenemase genotypes among Acinetobacter calcoaceticus isolates infected after liver transplantation. METHODS The 5.4 software was used to analyze the resistance of Acinetobacter species. Eight strains of imipenem-resistant A. calcoaceticus which were resistant to multiple drugs were collected. Analytical isoelectric focusing electrophoresis was used to measure the pI of the ?-lactamase. The homology of the isolates was determined by pulsed field gel electrophoresis(PFGE). blaTEM, blaSHV, blaIMP, blaVIM, blaOXA Genes for resistant isolates were amplified and sequenced. RESULTS Imipenem-resistant A. calcoaceticus infected after liver transplantation was resistant to multiple drugs. All of 8 strains were produced OXA-23 carbapenemases (pI of 6.7). The results of PFGE indicated there was a trend of resistant clone transmisstion in the transplantation ward. CONCLUSIONS There is a transmisstion of A. calcoaceticus producing OXA-23 carbapenemase in the transplantation ward of our hospital. It is important to monitor powerfully the bacterial resistance to control infection more effectively.

Objective To observe the effects of therapy of tonifying kidney and replenishing essence on protein expression profile in testes of aged rats.Methods Twenty male SD rats with 22 months old were equally randomized into the blank control group and the treatment group.The treatment group received gastric gavage of herbs at the dose of 0.05g?kg-1.d-1,which has the actions of tonifying kidney and replenishing essence.The treatment lasted 60 days.After treatment,the right testes were taken out from the rats,and the differentially expressed proteins in the rats testes of two groups were analyzed by two-dimensional gel electrophoresis(2-DE).Results Compared with the model group,obvious changes were found in 7 kinds of differentially expressed proteins in rats testes of the treatment group,of which 4 kinds were up-regulated and 3 down-regulated.After digestion and identification by the matrix-assisted laser desorption/ionization-time of flight (MALDI-TOF) mass spectrum,5 kinds from the 7 kinds of proteins were identified as phosphatidyl ethanolamine-binding protein(PEBP),heat shock 70 kDa protein 8,triose-phosphate isomerase,glyceraldehyde-3-phosphate dehydrogenase(GAPDH),and glutathione S-transferase Mu 1(GSTM1-1).Conclusion The anti-aging mechanism of therapy of tonifying kidney and replenishing essence is probably related with the regulation of testis protein expression in aged rats.

Objective:To study the clinicopathologic features of IgG4-related pulmonary inflammatory pseudotumor (IRPIP), and its correlations with CD4+T lymphocytes and interleukin-10 (IL-10) expression,and to investigate the immunopathological factors in the disease of IgG4-related pulmonary inflammatory pseudotumor .Methods: Expressions of IL-10, CD3, CD20, CD4, CD8 were examined by immunohistochemistry in 17 cases of IgG4-related pulmonary inflammatory pseudotumor tissues and 15 cases of IgG4-nonrelated pulmonary inflammatory pseudotumor tissues ( INPIP) .To analyze the differences of these indexes expression between IRPIP and INPIP.Results: In group of IRPIP, the CD4+T lymphocytes number and the ratio of CD 4+T lymphocytes number/CD8+T lymphocytes number were all apparently higher than those in the group of INPIP (P=0.006,0.023,respectively).The cells numbers of CD3,CD8,IL-10 positive expression in IRPIP were higer than those in INPIP ,and the cells number of CD20 positive expression in IRPIP was lower than that in INPIP,but these differences all had no statistical significance (P>0.05).In IRPIP,the number of IgG4+plasmacytes was positively related to the number of IL-10+cell (r=0.517),the correlation had statistical significance (P=0.033). Conclusion:The number of CD4+T lymphocytes increased in addition to the increased number of IgG 4+plasmacytes in the lesion back-ground of IRPIP,and the number of IgG4+plasmacytes was positively related to the number of IL-10+cells.It is suggested that the increased number of Th 2 lymphocyte and the increased secretion of cytokine IL-10were are immunopathological factors participated in the disease of IRPIP .

Objective To (e)xplore inhibition of endothelial progenitor cells (EPCs) against hepatic vein thrombosis after allogeneic bone marrow transplantation (BMT).Methods Balb/c mice were randomly divided into three groups: (1) BMT group [Balb/c mice were injected intravenously with 5 × 106 bone marrow cells after total body irradiation (TBI)]; (2) EPCs co-transfusion with bone marrow cells group: 5 × 105 EPCs were infused into recipient mice simultaneously; (3) Normal control group.Liver index was detected on the day 0,5,10,15 and 20 after transplantation.Hepatic vein thrombosis,hepatic cells and vascular endothelial damage were observed under the light microscopy after H&E staining.The injury of liver cells,liver veins,hepatic sinusoidal endothelial cells (SECs)and platelet adhesion conditions were observed under a transmission electron microscope (TEM).The proportion of activated platelets and TNF-α concentration in peripheral blood were detected by using flow cytometry.Results On the day 0,5,10,15 and 20 after transplantation,the proportion of activated platelets,liver index and TNF-α concentrations in BMT group and EPCs co-transfusion group showed an upward trend,peaked on the 15th day,and then decreased.However,they were still significantly higher than those in normal control group (P＜0.05).The above parameters in EPCs co-transfusion group at each time point were significantly lower than those in BMT group (P＜0.05).As compared with BMT group,platelet adhesion decreased,hepatic vein thromboses were reduced,hepatocyte swelling and necrosis were alleviated,and liver damage repaired rapidly in EPCs co-transfusion group.Conclusion EPCs co-transfusion with bone marrow cells could inhibit the hepatic veins thrombosis and ameliorate liver damage significantly.
