Objective To explore the effect of transport procedure adopted on intra-hospital transport of critically ill patients. Methods Three hundred and fifteen critically ill patients(control group)were intra-hospital transported adopting traditional method,while 309 ones(experimental group)adopting transport procedure. The occurrence rate of accidents of both groups and satisfactory rate of nurses in which the patients were admitted.Result The occurrence rate of accidents in experiment group was lower than that in control group and the satisfactory rate of nurses on transport procedure was higher than that on traditional method with statistical difference(P<0.01).Conclusion The application of transport procedure can effectively minimize the risk of critically ill patients during intra-hospital transport and increase satisfactory rate of medical staffs.

Objective: To observe the changes of free amino acids (FAAs) in plasma and brain of rats during simulated sea sickness and post–adaptation. Method: Pica or kaolin consumption was used as an indicator to judge the development of sea sickness and adaptation when SD rats were stimulated by Crampton sea sickness simulator. FAAs concentrations in plasma and brain of rats were determined by high performance liquid chromatography (HPLC) after simulated sea sickness and post-adaptation. Results: After simulated sea sickness stimulation for 1 d, the levels of Cys and Ile were increased, and Gly and Pro decreased significantly in plasma. The increase of BCAA/AAA ratio was also found. In brain, the contents of Ala, Cys+Met, Tyr, His, and total amino acids were remarkably decreased. After simulated sea sickness stimulation for 21 d, no changes of FAAs were observed in plasma and brain but the ratio of Glu/ GABA was increased in brain. There were no differences of FAAs, Glu/GABA ratio and BCAA/AAA ratio in plasma and brain of tolerant and susceptible sea sickness rats. Conclusion: The levels of amino acids, especially those related to neurotransmitter synthesis, in plasma and brain were changed significantly during sea sickness.

Methods: Sixty-four SD rats inflicted by 30% TBSA Ⅲ degree scalds were randomly divided into enteral nutrition with rhGH (ENGH) and enteral nutrition (EN) groups. Two groups animal were fed isocaloric enteral nutrition. Lymphocyte subsets, serum albumin, transferrin, serum levels of immunoglobulins,endotoxin,IL-6,TNF-? were determined on the 1st,4th,7th and 10th day postburn. Results: There were significant postburn changes in inflammatory responses, immunological variables in both groups.CD3 + 、CD4 + 、CD4 + /CD8 + in ENGH group were higher(P

Objective: Recent studies have suggested that congestive heart failure(CHF) is related to neuroendocrine system and cytokines,and its activation contributes to myocardial remodeling and leads to the development and progression of CHF.Tumour necrosis factor-?(TNF-?) is one of the most important factors.This study intends to establish the animal model of isoproterenol(ISO)-induced CHF in rats and to study the changes of serum TNF-?.Methods:Male SD rats were randomly allocated to the ISO-induced CHF group(n=50) receiving two subcutaneous injections of 170mg ISO per kilogram of body and the healthy control group(n=10) receiving two subcutaneous injections of 0.25ml normal saline.At 18th week,the hemodynamic parameters including HR,LVSP,LVEDP and ?dp/dtmax were assessed.TNF-? in plasma were all detected.Results:Compared with the control group,the LVSP、?dp/dtmax significantly decreased and the HR,LVEDP enlarged notably in CHF group(P

ObjectiveTostudytheinhibitioneffectof c-mycASODN(antisense oligodeoxynucleotide) and 5-FU (5-fluorouracil) on the expression of c-myc gene and the proliferation of human hepatomacellsHEPG-2. MethodsAfter treatedbyliposomemediatedc-mycantisense phosphorothioate oligodeoxynucleotide (APSODN) and 5-FU, the growth inhibition rate was detected by MTT assay, the expression of c-myc mRNA was detected by RT-PCR and immunohistocehemical methods HEPG-2cells. The cell cycle was analyzed by flow cytometric analysis. The morphological changes were observed by fluorescence staining and cellular genome electrophoresis. ResultsAfter sealing c-myc gene with ASODN,the growth of cells was repressed and the effect was time-dependent and dose-dependent ( P = 0. 02 ). The ability of proliferation decreased, the expression of c-myc gene was inhibited on transcription and translation levels; 5-FU can induce apoptosis of hepatoma cells HEPG-2 dramatically with the dose of 10 μ mol/L, when treated by both c-myc ASODN and 5-FU, HEPG-2 cells was induced apoptosis in a cooperative style ( P =0. 01 ).ConclusionsThe liposome mediated c-myc (APSODN) and 5-FU can inhibit the proliferation of HEPG-2 cells by inhibiting the expression of c-myc gene and can induce apoptosis of hepatoma cells HEPG-2 in a cooperative style. c-myc ( APSODN ) can increase the sensitivity of 5-FU to hepatoma cells and decrease the effective concentration of 5-FU.

Objective: To observe the effect of extracorporeal shock wave therapy (ESWT) on proliferation, cell cycle and intercellular adhesion molecule-1 (ICAM-1) expression in human umbilical vein endothelial cells (HUVECs). Methods: HUVECs were culturedin vitro at the concentration of (1×105/ml) and the cells were divided into 2 sets of groups:CSWT group, the cells were treated by different energy of (0.03, 0.09, 0.18, 0.24) mJ/mm2 respectively and corresponding Control group, in which the cells had no CSWT. HUVEC proliferation was detected by CCK colorimetric method, cell cycle was measured by lfow cytometry, mRNA and protein expressions of ICAM-1 were examined by RT-PCR and Western blot analysis respectively. Results: Compared with Control group, (0.09 mJ/mm2) CSWT group had promoted HUVECs proliferation,P<0.05 and the other CSWT groups were similar to corresponding Control groups,P>0.05; (0.09 mJ/mm2) CSWT group showed decreased proportion of G0/G1 stage and increased S and G2/M stages, allP<0.05; while (0.03 mJ/mm2) CSWT group only increased the proportion of G2/M stage,P<0.05 and the other CSWT groups were similar to corresponding Control group,P>0.05. Compared with Control group, (0.09 mJ/mm2 ) and (0.03mJ/mm2) CSWT groups showed increased mRNA expression of ICAM-1 (9.27±0.95) vs (1.02±0.27),P<0.001 and (7.08±0.60) vs (1.02±0.27),P<0.01; (0.09 mJ /mm2) CSWT group had elevated protein expression of ICAM-1,P<0.05. Conclusion: ESWT especially at (0.09 mJ/mm2) may accelerate cell cycle transition from G0/G1 stage to S and G2/M stages, promote HUVECs proliferation and increase ICAM-1 expression which may play important roles in ESWT facilitated angiogenesis in vitro.

BACKGROUND:Studies have shown that extracorporeal shock wave therapy is an effective, safe, and non-invasive treatment for ischemic heart disease, which can improve angiogenesis in the ischemic myocardium. OBJECTIVE:To summarize the research advances in promotion of angiogenesis for ischemic myocardium by extracorporeal shock wave therapy. METHODS:A computer-based online search of PubMed database and CNKI database was performed for relevant articles published between 1998 and 2014 with key words of “shock wave, ischemic heart disease, angiogenesis, cytokine, stem cel” in English and Chinese, respectively. Articles related to the promotion of angiogenesis for ischemic cardiovascular disease by extracorporeal shock wave were selected. Repetitive articles were excluded. According to inclusion criteria, 51 literatures were selected in result analysis. RESULTS AND CONCLUSION: Extracorporeal shock wave therapy can improve angiogenesis in the ischemic myocardium by mobilizing proliferation and differentiation of stem cels into vascular endothelial cels, and by enhancing the expression of growth factors such as vascular endothelial growth factor and basic fibroblast growth factor. Moreover, the extracorporeal shock wave therapy can create a local favorable microenvironment for angiogenesis by inhibiting inflammation, oxidative stress and apoptosis and by regulating components of the extracelular matrix. Extracorporeal shock wave therapy plays an important role in the angiogenesis of ischemic myocardium and displays a good clinical prospect in the treatment of ischemic heart disease. However, the specific mechanism requires further studies.
