Objective To study the antibacterial property of silver loaded titanium dioxide (TiO2) antibacterial coated endotracheal intubation tube,and to determine the minimum effective antibacterial concentration.Methods Intubation tubes coated with different concentrations of antibacterial agents were prepared with sol gel method.Polyethylene endotracheal intubation tubes were used as substrate,and silver loaded TiO2 was used as the antibacterial agent.According to the different antibacterial concentrations of the antibacterial agent,the tubes were divided into nine groups:10.0％ group,5.0％ group,2.0％ group,1.5％ group,1.0％ group,0.8％ group,0.6％ group,0.2％ group,and conrol group.They were respectively immersed in three standard bacteria suspensions with 1.0 × l05 cfu/mL:Pseudomonas aeruginosa,Staphylococcus aureus,and Escherichia coll Together with standard bacteria liquid group,there were 10 experimental groups.They were kept overnight for 24 hours.10 μL of respective culture medium was smeared on blood agar culture medium.After being cultured overnight in 35 ℃,the number of bacteria colonies was respectively counted.Results In 1.0 × 105 cfu/mL of three standard bacteria liquids with antibacterial agent concentration≥ 1.0％,three bacterial colonies had un-obviously growth rate.Almost the same strong antibacterial effects to achieve sterilizing rates of more than 98％ was shown in each group of the antibacterial coating endotracheal intubation tubes (all P＞0.05).As the antibacterial agent concentration decreased,three bacterial colonies were increasing gradually.Intermediate antibacterial effects were shown in tubes of 0.8％ group,with significant statistic difference as compared with 1.0％ and 0.6％ groups [Pseudomonas aeruginosa:7.300 (4.050,8.350) vs.0.200 (0.050,1.200),9.700 (9.000,10.000); Staphylococcus aureus:4.100 (3.300,4.650) vs.0.000 (0.000,0.150),5.800 (5.350,7.650); Escherichia coli:1.400 (0.750,3.750) vs.0.050 (0.025,0.050),9.500 (8.500,9.800),all P＜0.01].Conclusions Silver loaded TiO2 antibacterial coated endotracheal intubation tube had definite antibacterial properties,which were related to the antibacterial concentration.Strong antibacterial effects were shown when antibacterial concentration was above 1.0％,with bacteria almost completely killed in the immersing liquid.

Objective The different distribution and clinical significance of mean platelet volume (MPV) in the healthy normoglycemic and impaired fasting glucose (IFG) individuals were discussed.Methods The 499 individuals including 184 male and 315 female,who had undergone health checks in Tianjin Huanhu Hospital during May and July 2012 were studied retrospectively.Average age is forty-five ( thirty-five to eighty).Subjects were categorized into four groups according to fasting plasma glucose ( FPG) levels:G1 (3.89 mmol/L≤FPG<5 mmol/L, n=125),G2(5 mmol/L≤FPG <5.5 mmol/L, n=121), G3(5.5 mmol/L≤FPG<6.1 mmol/L, n=142), and G4(6.1 mmol/L≤FPG<7 mmol/L, n=111).G1, G2, and G3 are defined as normal FPG groups and G 4 is defined as IFG group.Eighty-nine cases in the same age patients with type II diabetes mellitus group ( G5 ) were observed at the same time.Results The MPV increased with the increasing FPG levels in the following order:G1(8.62 ±0.77) fl, G2 (8.85 ±0.80) fl, G3(8.90 ±0.69) fl,G4(9.14 ±0.78) fl and G5(12.03 ±1.42) fl.MPV[(12.03 ±1.42) fl] of type Ⅱdiabetes mellitus group(G5) was higher than that in the IFG group (G4)[(9.14 ±0.78) fl] and normal FPG groups[G1(8.62 ±0.77) fl,G2(8.85 ±0.80) fl,G3(8.90 ±0.69) fl] (F=12.773,P<0.01);MPV of the IFG group [ ( 9.14 ±0.78 ) fl ] was significantly higher than that in normal FPG groups [ G1 (8.62 ±0.77) fl,G2(8.85 ±0.80) fl,G3(8.90 ±0.69) fl] (F=12.773,P<0.01 for G4 vs.G1 and G2, P<0.05 for G4 vs.G3) ;MPV in the high-normal glucose group (G3) [(8.90 ±0.69) fl] was obviously higher than that in the low-normal glucose group (G1) [(8.62 ±0.77) fl] (F=12.773,P<0.05);MPV was positively associated with FPG in normal FPG groups ,IFG group and type Ⅱ diabetes mellitus group (G1-3:r=0.22, P<0.05;G4:r=0.26, P<0.01;G5:r=0.29, P<0.01).Conclusions Significant difference of MPV was observed in population of different FPG levels.Especially, MPV in IFG group was evidently higher than that in normal FPG group and was positively associated with FPG levels.

Objective To investigate the effects of trichostatin A (TSA) on Th1 and Th17 cells in the mice model of collagen induced arthritis (CIA).Methods Mice model of rheumatoid arthritis (RA) was induced in DBA/1 mice with type Ⅱ collagen.Paws were scored for histological severity of arthritis.The severity of inflammation of mice joints was evaluated by histological examination.Real time polymerase chain reaction (PCR) was used to determine mRNA of cytokines and transcriptional factors.Serum cytokine production was measured by enzyme linked immunosorbent assay (ELISA).T cell proliferation was examined by MTT method.One-way ANOVA and Student-Newman-Keuls were conducted in this study.Results The expressions of IFN-γand IL-17 mRNA of the CIA group were higher than that of the control group (8.27±0.64 vs 2.97±0.25,5.80±0.23 vs 0.70±0.26,all P＜0.01),but were inhibited significantly by TSA introduced at the onset of arthritis(6.60±0.52,2.50±0.41,all P＜0.01).Collagen specific T cell proliferation was significantly suppressed by the introduction of TSA.Increased level of IL-4 was observed in TSA treated group compared to that of CIA group(2.10±0.17 vs 1.01±0.08,P＜0.01).Conclusion Th1 and Th17 cells play crucial roles in the lesions of RA.TSA can suppress the progress of CIA by decreasing the percentage of Th1 and Th17.

Objective To compare the accuracy of bispectral index (BIS),Narcotrend index (NI),index of consciousness (IoC) versus auditory evoked potential index (AAI) in monitoring the depth of sedation induced by propofol.Methods Sixty ASA physical status Ⅰ or Ⅱ patients of both sexes,aged 41-64 yr,with body mass index 20-30 kg/m2,scheduled for elective surgeries under general anesthesia,were enrolled in the study.Propofol was given by target-controlled infusion (TCI) with the initial target effect-site concentration (Ce) of 0.8 μg/ml using Marsh pharmacokinetic model,and then the Ce of propofol was increased by 0.1 μg/ml,and OAA/S was performed.Before TCI of propofol,the values of BIS,NI,IoC and AAI were recorded,and at the same time the value of OAA/S score was 5.During TCI of propofol,when OAA/S score reached 4,3,2 and 1 in turn,the Ce of propofol was recorded,the sequence for determination of the values of BIS,NI,IoC and AAI was determined using a random number table,and the values were then recorded for 5 s after the values were stable and then averaged.The parameters for vital signs were maintained within the normal range.Pearson correlation of BIS,NI,IoC and AAI values with Ce of propofol was analyzed.Results The correlation coefficients of BIS,NI,IoC and AAI values with the Ce of propofol were rBIs-Ce =-0.829,rSI-Ce =-0.886,rloC-Ce =-0.881 and rAAI-Ce =-0.791,respectively.There was no significant difference between rBIS-Ce,rNI-Ce,rIoC-Ce and rAAI-Ce.Conclusion There are no significant differences in the accuracy of BIS,NI,IoC or AAI in monitoring the depth of sedation induced by propofol in middle-aged patients with non-noxious stimuli.

Objective To investigate the tumor-inhibitory effect of cytokine-induced killer cells(CIK)co-cul-tured with dendritic cells (DC)pulsed by breast cancer stem cell antigen on the same tumor-bearing mice. Methods Breast cancer stem cells were isolated from the cell line of MCF-7/ADR and extract lyses antigen of the stem cell was saved. DC and CIK derived from peripheral blood mononuclear cells of healthy individuals were co-cultured and pulsed or un-pulsed by the above antigen lyses. This DC+CIK were injected to breast tumorbearing mice (BCSC-AP-DC+CIK group), and were used to compared with the common breast cancer cell antigen (rather than breast cancer stem cell antigen) pulsed DC+CIK group(AP-DC+CIK group), DC+CIK group, CIK CIK group and normal saline group(NS group). The tumor-inhibitory effect were evaluated and compared among all 5 groups through the tumor size, TdT-mediated dUTP nick end labeling test (TUNEL), examining expression level of bcl-2 and bax by immunohistochemistry. Results The tumor size in each group before and after therapy and the tumor size after therapy between each group was of significant difference(P＜0.05). The maximum size is NS group(3.625±0.093)cm3 and BCSC-AP-DC+CIK group is minimum,which is (1.234±0.131)cm3. BC-SC-AP-DC+CIK group is of highest expression of bax and apoptotic index value, lowest bcl-2 expression in all 5 groups. Conclusion The CIK co-cultured with DC pulsed breast cancer stem cell antigen was more effective to induce apoptosis of breast cancer cells than those of CIK cells co-cultured with DC pulsed breast cancer cell antigen,CIK cells co-cultured with DC and CIK cells.

This study aimed at exploring the features of the body constitution and syndrome types of TCM in patients with pSS.General information of 60 patients with pSS was collected.Their TCM syndrome types and TCM body constitution types were examed,while the distribution of pSS syndrome types in terms of their body constitution was analyzed.Among 60 pSS patients,58 of them (96.67％) were female with the average age of 52 years and an average course of 63 months.Their usual residence was Xinjiang.Their most common first symptoms included thirst,dry eyes and joint pain,and the damage of skin and mucous membranes and blood system was rare.It was found that the syndrome of both qi and yin deficiency was the most common (48.33％),followed by the impregnation syndrome of heat and dampness (26.67％) and the syndrome of the weakness of spleen qi (25％) in pSS patients.Yin deficiency (58.33％) and yang deficiency (58.33％) in the body constitution of TCM accounted for decent proportions,followed by the constitutions of qi stagnation (48.33％),qi deficiency (45.00％),blood stasis (38.33％),phlegm-dampness (36.67％),damp-heat (18.33％),allergic (13.33％) and yin-yang harmony (1.67％).Those without the health education of pSS accounted for 51.11％ in cases of palindromia.In conclusion,yin deficiency and yang deficiency constitutions were most common,at most,the body constitution of both qi and yin deficiency,in pSS patients in accordance with TCM body constitution.Most pSS patients of palindromia didn't received professional health education of pSS.All the causes above suggested that we should make individualized treatment programs according to clinical syndrome types and the characteristics of TCM body constitution in pSS patients for strengthening the health management of pSS and improving their quality of life.
