0.05).Conclusion:Modified osteotomy can not improve operative effect.

Objective To detect the changes of interleukin-18 (IL-18) in plasma of trauma patients and evaluate their value in early warning of organ dysfunction. Methods A prospective study was carried out in 54 trauma patients admitted in from March 2001 to September 2002, which were divided into low injury severity score(ISS) group (Group L-ISS) and high ISS group (Group H-ISS). ELISA was applied to measure the level of IL-18 of blood samples that were collected on arrival, at days 4, 7 and 14 following admission. In the meantime, IL-18 level of plasma samples from patients with systemic inflammatory response syndrome (SIRS), sepsis and multiorgan dysfunction syndrome (MODS) was retrospectively analyzed so as to calculate the critical value of IL-18 in predicting organ dysfunction. Results After trauma, IL-18 concentration of plasma reached peak at days 4 and 7, and decreased gradually at day 14, which was significantly related to SIRS, sepsis and MODS, respectively. The IL-18 level was high relatively in plasma from patients with organ dysfunction. The higher IL-18 level in plasma within seven days after trauma indicated the severer organ dysfunction. Conclusion IL-18 is sensitive in early warning of organ dysfunction after trauma.

Objective To investigate the effect of sasanquasaponin (SQS) on injury of endothelial cells induced by hypoxia-reoxygenation and neutrophil adhesion, and its possible mechanisms. Methods Human umbilical vein endothelial cells (HUVEC) were exposed to normoxia or hypoxia-reoxygenation in the absence or presence of SQS (10.0, 1.0, and 0.1 ?mol/L). Lactate dehydrogenase (LDH) activity was determined in cultured HUVEC supernatants. HUVEC survival rate, neutrophil adhesion rate, malondialdehyde (MDA) level superoxide dismutase (SOD) and glutathione peroxidase (GSH-Px) activities were measured. Neutrophil adhesion was assayed in additional HUVEC treated as above. Results The results showed that hypoxia-reoxygenation resulted in HUVEC injury and enhancement of neutrophil adhesion, with the increase in LDH activity, MDA level, and adhesion rate as well, conversely, with the decrease in activity of SOD and GSH-Px; SQS antagonized these changes in a concentration-dependent manner. Conclusion SQS may protect HUVEC against hypoxia-reoxygenation injury and its mechanism appeares to be related to anti-lipoperoxidization and anti-adhesion of white blood cell.

In this cross-sectional study, consecutive Chinese Han ethnic inpatients in the Division of Cardiology, the First Affiliated Hospital of Soochow University from January 1, 2010 to December 31, 2013 were included. According to the exclusion criteria, 9 587 patients [1 604 with type 2 diabetes mellitus (T2DM) and 7 983 without T2DM]were obtained for final analysis. Logistic regression model was used to analyze the association of ApoB/A-1 ratio with T2DM and the possible interactions between ApoB/A-1 ratio and other risk factors. The results showed that the distribution of ApoB/A-1 ratio was positively skewed in Chinese Han ethic population. The median of ApoB/A-1 ratio of female was lower than that of male (0.68 vs 0.73,P<0.01). In all groups, the proportion of T2DM was increased with the raised ApoB/A-1 ratio. By the stratification analyses of sex, age, coronary artery disease, and the use of statins, ApoB/A-1 ratio was still correlated with T2DM. There existed significant interactions between ApoB/A-1 ratio and the smoking status or creatinine in T2DM.

Objective To investigate the effects of ghrelin on proliferation of vascular smooth muscle cells(VSMC)and the expression of mitochondrial fusion 2(Mfn-2)in cultured human aortic smooth muscle cells(HASMCs).Methods HASMCs were cultured in vitro,treated with different concentrations(10-9,10-8,10-7,10-6,10-5 mol/L)ghrelin or 10-6 mol/L ghrelin for different time(0,6,12,18,24 h).Subconfluent HASMCs at passage 4-6 were used in experiments.MTT essay was used to investigate the effect on proliferation of HASMCs.RT-PCR and Western blot were used to analyse the expression of Mfn-2.Results 10-7-10-5 mol/L ghrelin inhibited the proliferation of HASMCs,and the inhibitory effect of concentration of 10-6 mol/L was the most obvious(P<0.01).Ghrelin inhibited the proliferation of HASMCs in 6-24 h,and it reached the peak at 24 h(P<0.01).10-6 mol/L ghrelin significantly increased the expression of Mfn-2 mRNA and protein(P<0.01).The up-regulation of 10-6 mol/L ghrelin on Mfn-2 mRNA and protein expression reached the peak at 18 h(P<0.01).Conclusion Ghrelin might inhibit the proliferation of HASMC by up-regulating the expression of Mfn-2.

Objective To demonstrate the effect of tumor necrosis factor-α induced protein 8 like-2 (TIPE2) expression in patients with acute respiratory distress syndrome (ARDS) and its mechanism. Methods A prospective observation was conducted. Thirty-nine patients with ARDS admitted to department of emergency of PLA General Hospital from July 2013 to July 2015 were enrolled, and 35 healthy persons served as control group. The acute physiology and chronic health evaluation Ⅱ (APACHE Ⅱ) score within 24 hours after admission, blood gas analysis, procalcitonin (PCT), and C-reactive protein (CRP) were recorded. The mRNA expressions of TIPE2 in peripheral blood mononuclear cell (PBMC) and myxoma resistance protein 1 (MX1) in plasma were determined by real-time quantitative reverse transcription-polymerase chain reaction (RT-PCR). The correlations were analyzed by Spearman rank correlation analysis. Results The mean of APACHE Ⅱ score in 39 patients with ARDS was 25±3, the mean of PCT was (1.85±0.41) μg/L, and the mean of CRP was (18.0±3.0) mg/L. The TIPE2 mRNA expression in PBMC of ARDS patients was significantly down-regulated as compared with that of healthy control group (2-ΔΔCt: 3.28±0.15 vs. 8.87±0.20, P < 0.001), and the MX-1 mRNA expression in plasma was significantly higher than that of healthy control group (2-ΔΔCt: 39.44±0.46 vs. 20.10±0.32, P < 0.001). It was shown by correlation analysis results that the TIPE2 mRNA expression was negatively correlated with MX1 mRNA expression (r = -0.630, P < 0.001), so as APACHE Ⅱ score (r = -0.781, P < 0.001), but no correlation was found between TIPE2 mRNA and PCT as well as CRP (r value was 0.143 and 0.330, respectively, both P > 0.05). The MX1 mRNA expression was positively correlated with APACHE Ⅱ score (r = 0.893, P < 0.001), but no correlation was found between MX1 mRNA and PCT as well as CRP (r value was 0.230 and 0.210, respectively, both P > 0.05). Conclusion TIPE2 expression was decreased in ARDS patients, which negatively correlate with disease severity, and indicate TIPE2 might be involved in the pathogenic process of ARDS.

Objective To quantitative analyze the injury degree of cervical cord in cervical spondylotic myelopathy (CSM) patients using fractional anisotropy (FA) entropy of diffusion tensor imaging (DTI).Methods Twenty-four CSM patients and well-match healthy volunteers underwent cervical cord DTI scanning.FA value was measured at each segment of spinal cord (including grey matter and white matter) of spinal cord level and intervertebral disc level.Further Shannon entropy of FA value was calculated in each segment to observe the disorder degree of cervical cord structure in CSM patients.After the analysis of homogeneity of variance,two samples t test analysis was used to identify FC's differences of FA and Shannon entropy of FA value between the two groups.Result In CSM group,the average FA value of whole cervical cord was 0.644 ± 0.056,while it was 0.672 ± 0.035 in the healthy control group.There was significant difference of FA values between the two groups (t=-2.049,P=0.046).The FA entropy of CSM patients' cervical cord was 0.687±0.043,while it was 0.854±0.027 in the healthy control group.The FA entropy of CSM patients' cervical cord was lower than that of control group.There was significant difference of FA entropy between the two groups (t=-12.100,P＜0.001).The significant difference between the two groups was only found at C6 level for each level's FA value.The FA entropy of CSM patients' cervical cord was significantly lower than that of control group for every level.Conclusion This decreased FA entropy of cervical cord in CSM patients indicates that FA entropy can be used to detect the disorder of cervical cord structure in CSM patients.

Objective To investigate the immunological activity change of regulatory T cells (Treg) and discuss its significance in the outcomes of patients with multiple organ dysfunction syndrome (MODS) and severe burn. Methods A total of 106 patients with total burn surface area (TBSA) larger than 30% were included in the study and randomly divided into three groups according to the burn area: Group Ⅰ (TBSA of 30%-49%, n = 41), Group Ⅱ (TBSA of 50% -69%, n = 34) and Group Ⅲ (TBSA of 70%-99%, n = 31). According to the development of MODS, patients were divided into MODS group (n =21) and non-MODS group (n =85). The patients with MODS were further divided into non-survival group (n = 16) and survival group (n = 5) based on their outcomes. Healthy volunteers were served as normal control (n = 25). Peripheral blood samples were collected at days 1,3,7, 14 and 21 postburn. The immunomagnetic separation technique was applied to separate and purify CD4+ CD25+Tregs in peripheral blood, and phenotypes (CTLA-4) were analyzed by flow cytometry and the contents of interleukin-10 released in the supernatants were determined by ELISA. Results Expression of CTLA-4 and level of IL-10 were significantly increased in burn patients compared with normal control group, with statistical differences. The expression of CTLA-4 and level of IL-10 were significantly increased in patients with severe burns at all time points. The expression of CTLA-4 and level of IL-10 in MODS group were much higher than those in non-MODS group at days 3-21 postburn (P ＜ 0.01). Among the MODS patients, the expression of CTLA-4 and level of IL-10 in the survival group were obviously lower than those in the non-survival group at days 3-21 postburn (P ＜ 0.05 or P ＜ 0.01). Conclusions After severe burn injury, expressions of the markers on CD4 + CD25 + Treg surface and secretion of cytokines produced by CD4 + CD25 + Tregs show significant difference in patients with different born areas, MODS development and survival state. CD4 + CD25 + Treg may play an important role in the pathogenesis of immunoregulation, MODS and mortality of burn patients through secretion of inhibitory cytokines.
