OBJECTIVE To find out the situation of peri-operational lower respiratory tract infection in inpatients with congenital heart disease of left to right shunt and provide evidence for clinical prevention and treatment.METHODS Peri-operational lower respiratory tract nosocomial infection in 2 564 cases of congenital heart disease with left to right shunt during Jan 2003 to Dec 2005 was analyzed retrospectively.RESULTS The incidence rate of lower respiratory tract infection was 11.27% among 2 564 cases.The incidence rate was 15.51% in patients less than 2 years old.The most common pathogen was Pseudomonas aeruginosa(18.60%).The death rate in cases with lower respiratory tract nosocomial infection was higher than these non-infection cases.CONCLUSIONS Pulmonary congestion,less than 2 years old,mechanical ventilation and antibiotics abuse are main causes of lower respiratory tract nosocomial infection in patients with congenital heart disease with left to right shunt.Nosocomial infection can increase death rate.

Objective To investigate the status of the knowledge of metabolic syndrome and their demand situation among community nurses and discuss the community nursing intervention on metabolic syndrome. Methods A survey about the knowledge and its needs of metabolic syndrome was conducted in community nurses of the practice bases of the nursing school of Zhejiang Traditional Chinese Medical University by selfdesigned questionnaires. Results 58.8% of the communities had carried out the prevention of metabolic syndrome, and standard administration had been applied in 43.3% among them. 40.8% and 42.9% nurses were not clear about the diagnosis and prevention of metabolic syndrome respectively. 100.0% nurses agreed that corresponding training was necessary for them. Conclusions The education and training of the knowledge about metabolic syndrome must be enhanced for community nurses, and the intervention measures should be reinforced to improve the rate of diagnosis , cognition rate, control rate in order to improve the people's health and reduce the social and personal burden.

The serum levels of soluble E selectin (sE selectin) and soluble vascular cell adhesion molecule 1 (sVCAM 1) were determined by ELISA in impaired glucose tolerance (IGT) group (62 cases), normal glucose tolerance (NGT) group (24 subjects), and diabetes mellitus group (23 cases). Serum sVCAM 1 level in the IGT group was significantly higher than that in the NGT group (P

Objective To study the proliferation promoting effect on osteoblast cells induced by sodium orthovanadate and whether nitric oxide (NO) was involved in this process. Methods MTT assay was employed to determine cell proliferation and its inhibition. The level of NO was measured by enzyme reduction method. Results The MTT values of MC3T3-E1 cells under the 2.5,5.0,10.0 ?mol/L of sodium orthovanadate were 0.3380?0.0045, 0.3400?0.0141, 0.3840?0.0313 respectively, which were higher than in control group (0.2540?0.0167)(P

Objective To investigate the role of indoleamine 2,3-dioxygenase(IDO)in asthma.Methods The mouse asthma model was induced by ovalbumin(OVA).IDO expression was detected on the level of protein and mRNA respectively.Distribution and maturation of dendritic cells were detected by the immunofluorescence method.Results (1)The symptoms and lung inflammation in the model group were more serious than control group.The serum total IgE was significantly higher in the model group than that in the control group,165.50 ± 30.13 ng/ml vs.94.45 ± 28.30 ng/ml(P ＜ 0.05).(2)IDO expression in the model group was lower than that in control group.On the level of protein,mean intergrated optical density was 11.38 ± 6.05 in the model group vs.23.62 ± 8.92 in the control group(P ＜ 0.05);on the level of mRNA,IDO expression of the model group was 33% of the control group(P ＜ 0.05).(3)CD11c+CD86+ cells were distributed in alveolar wall and around small vessels.The quantity of CD11c+CD86+ cells in lungs of the model group were significantly smaller than that in the control group.The median intergrated fluorescence intensity was 9961.86(range,7 406.52 ～ 12 724.98)in the model group vs.15974.60(range,10 006.39 ～ 16 171.46)in the control group(P ＜ 0.05).Conclusions IDO expression is low and matured dendritic cells are less in situ in the asthma model.These suggest that less matured DCs may produce less IDO,which may play an important role in asthma.

Objective To study the regulatory role of chemerin in infant with respiratory syncytial virus (RSV) pneumonia by investigating the level of serum chemerin,pro-inlfammatory cytokine (TNF-α, IL-17), and anti-inlfammatory cytokine (IL-10, TGF-β). Methods The serum level of chemerin,TNF-α,IL-1,IL-10,TGF-βwere tested in 82 RSV pneumonia inpatients (17 severe RSV pneumonia cases,65 mild cases) and 40 controls by ELISA and the severity of the RSV pneumonia was evaluated using a scoring system. Results The serum level of chemerin of RSV pneumonia cases were (610.45±106.63pg/ml) which were signiifcantly higher than the control(337.24±43.37 pg/ml). Chemerin level of severe RSV pneumonia group is signiifcantly higher than mild cases as well [(786.62±82.59 pg/ml)vs (539.98±65.86 pg/ml)P<0.01 ]. Signiifcant positive correlations were found be-tween serum chemerin level and TNF-α,IL-17 level (r=0.81,r=0.61;P<0.01) while the serum level of chemerin is negatively correlated with IL-10, TGF-β(r=-0.80,r=-0.75;P<0.01). Conclusions The level of chemerin increased in RSV pneumonia patients,and related to clinical severity after RSV infection. These results indicate that chemerin may play an important role in the pathogenesis of RSV pneumonia and to the severity of the infection.

Objective: A high-performance liquid chromatographic (HPLC) procedure with a fluorescence detector was developed to rapidly separate ?,?,?,?- tocopherol isomers in human serum Methods: The HPLC system consisted of Inertsil silica column (100-A, 3?m,4.6mm?250mm) and 7% (v/v) methyl-tert- butyl ether in n-hexane as mobile phase . Prior to HPLC, the serum sample wa deproteined by ethanol (BHT 0.0625%) and the tocopherol isomers were efficiently extracted in thei original isomeric conformations using n-hexane-ethyl acetate (5:1) in the presence of 2,6-bi-buty p-methylphenol (BHT). Result: The quantification limits, defined as the lowest quantitatively measurable concentration of the different compounds (ng/ml) are calculated according to the experiment:?-tocophero 1.0,?-tocopherol 1.0,?-tocopherol 0.5,?-tocopherol 0.5. The recovery rates are between 95%~105% Correlation coefficients are over 0.999 when the concentration is between 5 ng/ml~5 ?g/ml. Conclusion This technique is suitable for assay of tocopherol isomers in human serum at all ages.

Objective To investigate the association between serum cytokines and depression and understand the effect of sertraline on serum leveI of interleukin 2(IL-2),interleukin 6(IL-6),tumor necrosis factor-α(TNF-α)and C-reactive protein(CRP).Methods A total of 50 depressive patients(study group) and 25 healthy controls(control group)were included in this study.The levels of serum IL-2,IL-6 and TNF-α were measured by enzymatic-linked immunosorbent assay(ELISA)on baseline and after treatment,CRP were measured by scatter rate nephelometry.Depressive patients were assessed by Hamilton depression sere(HAMD)on baseline and after treatment.Results The levels of IL-2(41.4±15.7)pg/ml,IL-6(63.4±17.2)pg/ml,TNF-α(81.4±19.3)pg/ml and CRP(8.2±2.9)mg/L in study group were significantly higher than those in control group(13.2±4.6)pg/ml,(21.3±7.7)ps/ml,(35.1±7.8)ps/ml,(2.9±0.5)mg/L,(P<0.01).Compared with baseline,the levels of serum IL-2(20.1±9.1)ps/ml,IL-6(38.5±11.6)pg/ml,TNF-a(49.5±12.6)pg/ml and CRP(4.2±1.6)mg/L after treatment by sertraline decreased significantly(P<0.01).In study group,there were significant positive correlations between the serum level of IL-2,IL-6,TNF-α and present age,the total score of HAMD(P<0.05,P<0.01).There were significant positive correlations between variation rates of serum IL-2,IL-6,TNF-αand reduction rate of HAMD(P<0.05,P<0.01).Conclusion The serum levels of IL-2,IL-6,TNF-α and CRP increased in patients with depression.Sertraline may affect depressive patients'serum levels of IL-2,IL-6,TNF-αand CRP.
