Objective To investigate the relationship of serum Th1/Th2 cytokine levels with liver function and their clinical significance in patients with alcoholic liver cirrhosis (ALC).Methods Thirty-four ALC patients,13 patients with viral liver cirrhosis (VLC),and 17 healthy controls were included in the study.Serum levels of Th1 cytokines (tumor necrosis factor (TNF)α,interferon (IFN)γ,and inter-leukin (IL)-12)and Th2 cytokines (IL-10,IL-4,IL-6,and IL-13)were measured by cytometric bead array,and their correlations with Child-Pugh classification,model of end-stage liver disease (MELD)score,and biochemical parameters of liver function were ana-lyzed.Comparison between multiple groups was made by Kruskal-Wallis H test,and comparison between two groups was made by Mann-Whitney U test.Correlation analysis was performed by Spearman rank test.Results The Th1 (TNFαand IFNγ)/Th2 (IL-10,IL-4, and IL-13)cytokine levels in ALC group were significantly lower than those in healthy control group (P<0.05),and these indices de-creased nonsignificantly as the Child-Pugh class increased.Compared with VLC patients,ALC patients had significantly increased Th1/Th2 cytokine levels except IL-4 level (P<0.05).In ALC patients,TNFα,IL-10,and IL-13 levels were positively correlated with pro-thrombin time activity (P<0.05)but negatively correlated with total bilirubin and MELD score (P<0.05);especially,the levels of IL-10,IL-13,IL-4,TNFα,and IFNγwere negatively correlated with daily alcohol consumption (P<0.05).Conclusion The expression of Th1/Th2 cytokines is significantly reduced in ALC patients and is correlated with alcohol intake and liver function damage.Monitoring se-rum Th1/Th2 cytokine levels in ALC patients is helpful for clinical treatment and prognostic evaluation.

Objective To comprehend the characters of sensory integration of children with brain injury and identify the effect of sensory integration training.Methods 127 children with brain injury were determined by the check form of sensory integration, Wechsler Preschool and Primary Scale of Intelligence (WPPSI), Wechsler Intelligence Scale for Children-China Recension (WISC-CR) and comprehensive function assessment for disabled children. These children were divided into the trial group (n=92) and control group (n=35). All children of two groups received rehabilitation training, but children of the trial group also received sensory integration training. The Results of them were compared before and after rehabilitation.Results The scores of the check form of sensory integration of the children with cerebral palsy were significantly higher than that of children with mental retardation (P<0.01). After rehabilitation training, the raising scores of comprehensive function assessment for disabled children of the trial group were significantly higher than the control group (P<0.01).Conclusion The ability of sensory integration are abnormal in children with brain injury. The sensory integration training can accelerate the comprehensive function of children with brain injury effectively.

Objective To measure the level of platelet derived growth factor-BB (PDGF-BB) in maintenance hemodialysis patients and investigate the significance of carotid atherosclerosis.Methods Thirty-six maintenance hemodialysis patients (test group) and 20 healthy controls (normal control group) were enrolled in this study.The level of PDGF-BB was measured by enzyme-linked immunosorbent assay in two groups.Intima-media thickness (IMT) and atherosclerotic plaques of the extracranial common carotid artery were measured by echocardiography.Results The level of IMT and the positive rate of carotid atherosclerosis in test group were significantly higher than those in normal control group [(1991.8 ± 228.6) μ mol/L vs.(71.2± 15.9) μmol/L,(36.78 ±3.40) g/Lvs.(41.96±2.07) g/L,(4.97 ±0.57) mmol/Lvs.(4.48 ±0.84) mmol/L][(1.01 ±0.23) mm vs.(0.72 ±0.15) mm,69.4％(25/36) vs.10.0％(2/20)](P＜ 0.01).The level of plasma creatinine,albumin and total cholesterol in test group were significantly higher than those in normal control group (P ＜ 0.01 or ＜ 0.05).The level of PDGF-BB in test group was significantly higher than that in normal control group[(93.27 ± 31.58) ng/L vs.(31.71 ± 15.78) ng/L,P ＜ 0.01].In test group,age and the level of PDGF-BB and triacylglycerol in carotid atherosclerosis patients were significantly higher than those in non-carotid atherosclerosis patients [(48.04 ± 9.97) years vs.(34.54 ± 10.35) years,(102.60 ± 32.87) ng/L vs.(72.06 ± 13.67) ng/L,(1.51 ± 0.59) mmol/L vs.(1.01 ± 0.27) mmol/L] (P ＜ 0.01).Regression analysis showed that age (β =0.346,P ＜ 0.01) and PDGF-BB (β =0.594,P＜ 0.01) were the important impacting factors for IMT.Conclusion The level of PDGF-BB is increased in maintenance hemodialysis patients,and it may play an important role in carotid atherosclerosis.

ObjectiveTo explore the changes and significances of cardiac troponin Ⅰ (cTnⅠ),myoglobin (Mb) and creatine kinase MB (CK-MB) in old patients with acute myocardial infarction(AMI).MethodThe levels of cTnⅠ, Mb and CK-MB in 89 cases with AMI patients (AMI group) and 100 healthy controls (control group) were detected and compared. ResultsThe levels of cTnⅠ, Mb and CK-MB in AMI group were ( 8.15 + 3.26) μ g/L, (478.45 ± 96.87 ) μ g/L and ( 128.17 ± 53.26 ) U/L, while were (0.03 ±0.02) μ g/L, (21.61 + 9.38 ) μ g/L and (9.53 ± 2.94) U/L in control group, the levels of cTnⅠ, Mb and CK-MB in AMI group were significantly higher than those in control group(P ＜ 0.05 ). The sensitivity rate of cTnⅠ,Mb and CK-MB for detecting AMI was 95.5％ (85/89), 97.8％ (87/89) and 87.6％ (78/89), and the specificity rate was 98.0％(98/100), 82.0％(82/100) and 94.0％(94/100).

Objective To study the role of cell density in the tyrosol production and morphology for Candida albicans biofilms. Methods C. albicans SC5314 and clinical isolates were propagated in yeast peptone dextrose (YPD) medium. Cells were collected by centrifugation and washed twice in sterile phosphate-buffered saline (PBS) before this study, then resuspended in RPMI 1640 supplemented with L-glutamine and adjusted to a desired concentration of 5 × 10~6 cells/ml, 5×10~5 cells/ml, 5 × 10~4 cells/ml, 5 × 10~3 cells/ml after counting with a hematocytometer. Standardized C. albicans cells were prepared as above description and 2000 μl of this standardized cell suspension was dispensed into the wells, then C. albicans biofilms were formed on the bottom of the polystyrene wells. In this study, tyrosol synthesized by SC5314 and clinical isolates of C. albicans biofilm was quantified by high performance liquid chromatography (HPLC). The effects of tyrosol on morphology of C. albicans biofilms were investigated by scanning electron microscopy (SEM). Results Tyrosol production of C. albicans biofilms was affected by cell densities. At lower inoculation size(5 μ 10~3 cells/ml), there was too less tyrosol production to be detected at the early stage of the biofilms formation. At higher inoculation size (5 μ10~6 cells/ml), tyrosol can be detectable at the early stage or at the mature stage of biofilms formation. There was a sharp increase in tyrosol concentration at 24 h, while there was a decrease in tyrosol concentration after that time from the strains when the strains were at an inoculation size of 5 × 10~6 cells/ml and 5 × 10~5 cells/ml. Cell densities affected the morphology formation of the C. albicans biofilms. At the early stage of the biofilms formation, C. albicans grew less germ tube at lower cell densities than that at the higher cell densities. With the mature of the biofilms, C. albicarts grew more hyphae at higher cell densities than that at the lower cell densities. All these above showed that cell densities played an important role in the propagation for the C. albi-cans in the biofilm formation. Conclusion Cell density play an important role in the formation of the C. albi-cans biofilms and the production of the tyrosol.
