Objective To study the association of the serum soluble intercellular adhesion molecule-1(SICAM-1) and soluble vascular cell adhesion molecule-1(SVCAM-1) with metabolic syndrome(MS) and its components. Methods The MS was defined by criteria of the international diabetes federation. The levels of SICAM-1 ,SVCAM-1,plasma glucose,insulin,lipids,uric acid, glycosylated haemoglobin A(1C), and blood viscosity were measured. Results The concentrations of SICAM-1 and SVCAM-1 were significantly higher in subjects with MS and its components than in those without them. The concentrations of SICAM-1 and SVCAM-1 were correlated positively with disorder number of BMI, WHR, SBP, DBP,FPG, 2 hour plasma glucose, triglyceride, uric acid, HbA1c, blood viscosity and HOMA-IR,and negatively with high density lipoprotein cholesterol. Conclusions The concentrations of SICAM-1 and SVCAM-1 rise with the increase of the number of MS components. Endothelial dysfunction might participate in the occurrence and development of MS.

Objective To investigate the levels of serum C-reactive protein in subjects with impaired fasting glycemia and its significance.Methods From Mar.to Sep.2005,according to oral 75 g glucose tolerance test(OGTT)in the patients in the First Hospital Affiliated to China Medical University,there are 30 subjects with normal glucose tolerance(NGT),28 cases with impaired fasting glycemia(IFG).CRP was detected with ELISA.Results (1)Serum CRP in the subjects with impaired fasting glycemia was significantly higher than those in normal subjects( P

Objective To investigate the difference of serum high sensitivity C-reactive protein(hs-CRP)concentrations in subjects with various glucose tolerances,and to analyze the correlation with insulin resistance.Methods A total of 90 subjects,who came from the Medical Examination Center of the First Hospital Affiliated to China Medical University from Oct.2004 to Apr.2005,were divided into five groups according to oral glucose tolerance test(OGTT):normal glucose tolerance(NGT)group;impaired fasting glucose(IFG)group;impaired glucose tolerance(IGT)group;IFG and IGT(IGT/IFG)group;newly diagnosed,complication-free type 2 diabetes(T2DM)group.By using the ELISA methods,the concentration of serum high sensitivity C-reactive protein(hs-CRP)was measured in these subjects,and its correlation with homeostasis model assessment insulin resistance index(HOMA-IR)was andlysed.Results The concentration of hs-CRP was significantly higher in IFG,IFG/IGT,T2DM than in NGT.The concentration of hs-CRP was positively correlated with glucose metabolism index and insulin resistance index.Conclusion Our study demonstrates that inflammation already exists not only in T2DM patients but also in subjects with IFG.Inflammation might participate in the occurance and development of T2DM.

Objective To investigate smoking status,knowledge of smoking hazards,attitude of tobacco control and skill of assisting smoking cessation of the staff in a teaching hospital in Chongqing and to provide references for the further construction of‘smoking-free hospital’. Methods General investi-gation was taken on the staff in a teaching hospital in Chongqing with a self-designed questionnaire. Main contents of questionnaire include:social demographic information,smoking status,awareness of tobacco hazard,willingness and methods of tobacco control,etc. All the data were inputted with software Epidata 3.1 and were analyzed with SPSS 13.0. Results The total smoking rate was 9.65%,with 30.49%for male, 2.75%for female and 12.50%for clinician. The age distribution of smoking staff was described as follow-ing:91.97% being under 50 year-old and more than 50.00% being 20-35 year-old. 52.43% of the surveyed did not know Framework Convention of Tobacco Control of WHO . Relatively ,most of the surveyed only knew well the relationship between respiratory diseases and tobacco use and the relation-ship between fetal abnormalities and tobacco use. 84.99%of the surveyed agreed with outdoor-smoking policy;83.56%of the surveyed claimed that they had discouraged smoking behaviors in public at various extents,14.20%of the surveyed agreed that assisting the public in smoking cessation was one of the aims of constructing‘smoking-free hospital’;70.00%clinicians claimed routinely inquiring and noting smok-ing status of patients, which was better than nurses and medical technicians;almost 30.00%clinic staff did not know quitting smoking drugs at all,approximately 70.00%clinic staff claimed a lack of confidence in smoking control and approximately 70.00% clinicians and nurses did not recommend pro-fessional methods of smoking cessation in practice. Conclusions Smoking staff in the teaching hospital are almost younger people,which is an alarm of the urgent need for tobacco control education. Most staff reach a consensus on keeping smoking-free environment in hospital,but they do not sufficiently acknowledge their social responsibility for tobacco control,and also there is a distance before they can serve as a smok-ing cessation assistant. Tobacco control must be incorporated in long-term mechanism of hospital con-struction. There are three steps in the construction of smoking-free hospital:①creating a smoking-free en-vironment in hospital;②encouraging patients to quit smoking and providing professional service of smoking cessation;③making a positive effort on social tobacco control and advocating smoking cessation in public.

Objective To explore the value of prenatal MRI signs in diagnosis of placenta accreta.Methods MRI data of 163 pregnant women with suspected placenta accreta were retrospectively reviewed.According to the results of cesarean section,they were divided into placenta accreta group (n =136) or without placenta accreta group (n =27).The differencesof MRI signs between the two groups were compared.Taking cesarean section results as the gold standard,the sensitivity,specificity,positive and negative predictive value of MRI signs were calculated,respectively.Results Uterine bulging,abnormal vessels and hypointense T2WI bands at junction of placental and myometrium,as well as uterine recess had statistical differences between the two groups (all P＜0.05).No statistical difference of placental heterogeneity,focal interruptions in myometrial wall,uterine penetration and parametrium implantation nor protrusion of placenta into cervix was found between the two groups (all P＞0.05).The MRI signs of uterine penetration and parametrium implantation,uterine recess,protrusion of placenta into cervix yielded a specificity and positive predictive value of 100％,respectively.Conclusion Prenatal MRI has high efficacy in the diagnosis of placenta accrete.Placenta accrete should be highly suspected especially in the presence of uterine penetration and parametrium implantation,uterine recess and protrusion of placenta into the cervix.

OBJECTIVE: To investigate the correlation between serum specific immunoglobin E(sIgE) and skin prick test(SPT) and their differences of the positive rate. METHOD: One hundred and nine patients with allergic rhinitis were detected the serum slgE. The patients had positive symptoms and signs, positive SPT results with at least one allergen. RESULT: Specific IgE and SPT results of Dp,Df and Artemisia showed a positive correlation (r = 0.520, 0.4413, 0.764, P < 0.01). sIgE positive rates were 55.0%, 54.1% and 17.4% for Dp, Df and Artemisia respectively, whereas SPT positive rates were 68.8%,79.8% and 27.5% respectively. The difference between the positive rates of the sIgE and SPT was significant (chi2 = 27.93,18. 20,60. 60, are P< 0.01). CONCLUSION There was a good correlation between specific IgE and SPT. SPT is more sensitive than sIgE, but SPT can not substitute for slgE,vice versa.
