16 and the distribution of severe trauma more than 2 anatomic parts.They were randomly divided into two groups:intensive insulin treatment group(n=31)and control group(n=31).Intensive insulin treatment group received insulin with insulin pump in order to maintain blood glucose levels at 4.0-6.1 mol/L,while the control group received routine insulin treatment in order to mmaintain blood glucose levels at 10.0- 11.0 mol/L.Plasma levels of TNF-?,IL-1,IL-6, CRP,APACHEⅡscores and cure rate were analyzed before and after the treatment.Data was expressed as mean?standard deviation.Two- tailed T test and ANOVA were used for comparison in SPSS 10.0,and changes were considered as statistically significant if P value was less than 0.05.Results After the intensive insulin treatment, patient's hemodynamic parameter apparently improved,APACHEⅡscores descended,and the levels of TNF-?, Ib-1,IL-6,CRP all declined,in comparison with control group,there were significant differences. Intensive insulin treatment might improve patient's general condition and decrease complications and mortality of severe multiple trauma.

BACKGROUND: Traumatic brain injury (TBI) is associated with most trauma-related deaths. Secondary brain injury is the leading cause of in-hospital deaths after traumatic brain injury. By early prevention and slowing of the initial pathophysiological mechanism of secondary brain injury, pre-hospital service can significantly reduce case-fatality rates of TBI. In China, the incidence of TBI is increasing and the proportion of severe TBI is much higher than that in other countries. The objective of this paper is to review the pre-hospital management of TBI in China. DATA SOURCES: A literature search was conducted in January 2014 using the China National Knowledge Infrastructure (CNKI). Articles on the assessment and treatment of TBI in pre-hospital settings practiced by Chinese doctors were identified. The information on the assessment and treatment of hypoxemia, hypotension, and brain herniation was extracted from the identified articles. RESULTS: Of the 471 articles identified, 65 met the selection criteria. The existing literature indicated that current practices of pre-hospital TBI management in China were sub-optimal and varied considerably across different regions. CONCLUSION: Since pre-hospital care is the weakest part of Chinese emergency care, appropriate training programs on pre-hospital TBI management are urgently needed in China.

Adhesion to extracellular matrix plays important roles in the regulation of survival, proliferation, differentiation and homing of hematopoietic cells and is regulated by a wide variety of growth factors, adhesion receptors and other ligands that mediate the cell to matrix and cell to cell interaction. Stem cell factor (SCF) plays important roles in the regulating growth and self-renewal of hematopoietic stem/progenitor cells. In the report, the effects of stem cell factor on the adhesion of hematopoietic cells to fibronectin were observed by using a hematopoietic growth factor dependent cell line-Mo7e. Results showed that Mo7e cells express the very late antigen VLA-4 (beta1 alpha4) and VLA-5 (beta1 alpha5) integrins. The expression of the SCF receptor (c-kit) was also detected in the Mo7e cells. SCF enhances the adhesion of Mo7e cells to fibronectin in a concentration dependent manner. SCF enhanced adhesion of Mo7e cells to fibronectin was blocked by anti-beta1, alpha4 and alpha5 antibodies. Addition of PI-3 kinase inhibitors also blocked the adhesion of Mo7e cells to fibronectin induced by SCF. It was concluded that SCF enhances the adhesion of Mo7e cells to fibronectin, and this process is mediated by integrins and PI-3 kinase pathway.

BACKGROUNDThe classic glycine receptor (GlyR) in the central nervous system is a ligand-gated membrane-spanning ion channel. Recent studies have provided evidence for the existence of GlyR in endothelial cells, renal proximal tubular cells and most leukocytes. In contrast, no evidence for GlyR in myocardial cells has been found so far. Our recent researches have showed that glycine could protect myocardial cells from the damage induced by lipopolysaccharide (LPS). Further studies suggest that myocardial cells could contain GlyR or binding site of glycine.

METHODSIn isolated rat heart damaged by LPS, the myocardial monophasic action potential (MAP), the heart rate (HR), the myocardial tension and the activities of lactate dehydrogenase (LDH) from the coronary effluent were determined. The concentration of intracellular free calcium ([Ca(2+)](i)) was measured in cardiomyocytes injured by LPS and by hypoxia/reoxygenation (H/R), which excludes the possibility that reduced calcium influx because of LPS neutralized by glycine. Immunohistochemistry was used to detect the GlyR in myocardial tissue. GlyR and its subunit in the purified cultured cardiomyocytes were identified by Western blotting.

RESULTSAlthough significant improvement in the MAP/MAPD(20), HR, and reduction in LDH release were observed in glycine + LPS hearts, myocardial tension did not recover. Further studies demonstrated that glycine could prevent rat mycordial cells from LPS and hypoxia/reoxygenation injury (no endotoxin) by attenuating calcium influx. Immunohistochemistry exhibited a positive green-fluorescence signaling along the cardiac muscle fibers. Western blotting shows that the purified cultured cardiomyocytes express GlyR beta subunit, but GlyR alpha1 subunit could not be detected.

CONCLUSIONSThe results suggest that glycine receptor is expressed in cardiomyocytes and participates in cytoprotection from LPS and hypoxia/reoxygenation injury. Glycine could directly activate GlyR on the cardiomyocytes and prevent calcium influx into the cardiomyocytes.

Objective: To evaluate the immunogenicity of HIV-1 clade C/B’ vaccine based on modified vaccinia virus Ankara (MVA) vector in mice. Methods: Mice were inoculated with 3-dose HIV vaccine by intramuscular injection. Blood sample were collected every second week, and then the antibodies against HIV were detected. At week 6, mice were killed and cellular immune responses were examined by ELISPOT. Result: The number of spot forming cells in the 107 pfu/ml -dose group was more than those of 105 pfu/ml -dose and 106 pfu/ml -dose groups significantly. HIV specific antibodies emerged at week 2 and elevated rapidly at week 4 and week 6. The level of specific IgG in the 107 pfu/ml -dose group was more than those of 105 pfu/ml -dose and 106 pfu/ml -dose groups significantly. Conclusion: The ADMVA induces both humoral immunoresponse and cellular immune responses.

OBJECTIVETo observe the change of cytokine interleukin IL-1 beta, IL-6, IL-10, tumor necrosis factor-alpha (TNF-alpha) occurred in acute paraquat (PQ) poisoning rats and to investigate the mechanism of acute lung injury caused by paraquat (PQ) poisoning.

METHODSAll 72 healthy adult Wistar rats were random assigned into normal control groups, paraquat high dose group (120 mg/kg), paraquat middle dose (60 mg/kg) group, paraquat low dose group (30 mg/kg). Three observing periods of time included 8, 24, 72 h and the standards of TNF-alpha, IL-1 beta, IL-6, IL-10 were determined.

RESULTSEvery index of the PQ group was significantly higher than that in the NS group at the same period of time (P<0.05 or P<0.01). In the 72 h group, the high dose group was significantly higher than the middle and low dose group (P<0.05), and there was no significantly difference between the middle and low dose group (P>0.05). For the comparison of index in the same dose group, the group of 72 h was much higher than 8 h group and 24 h group (P<0.05), and there was no difference between the 8h group and 24 h group (P>0.05).

CONCLUSIONThe cytokine may play an important role in paraquat-induced acute lung tissue injury.

Design space approach is applied in this study to enhance the robustness of first ethanol precipitation process of Codonopsis Radix (Dangshen) by optimizing parameters. Total flavonoid recovery, dry matter removal, and pigment removal were defined as the process critical quality attributes (CQAs). Plackett-Burman designed experiments were carried out to find the critical process parameters (CPPs). Dry matter content of concentrated extract (DMCE), mass ratio of ethanol to concentrated extract (E/C ratio) and concentration of ethanol (CEA) were identified as the CPPs. Box-Behnken designed experiments were performed to establish the quantitative models between CPPs and CQAs. Probability based design space was obtained and verified using Monte-Carlo simulation method. According to the verification results, the robustness of first ethanol precipitation process of Dangshen can be guaranteed by operating within the design space parameters. Recommended normal operation space are as follows: dry matter content of concentrated extract of 45.0% - 48.0%, E/C ratio of 2.48-2.80 g x g(-1), and the concentration of ethanol of 92.0% - 92.7%.
