Automated body fluid cytology analysis has been accepted by clinical laboratories gradually.The improvement of efficacy and analytical precision can overcome some defects of traditional manual method,such as time-consuming and poor repeatability.To make use of the advantages of automated fluid cell analysis technology,the automated method and microscopic method must be combined by setting review rules.Meanwhile,more attentions must be paied to sample collection and specimen preservation at pre-analytical stage,verification of instrument performance at analytical stage and necessary clinical communication at post-analytical stage.Only if a complete system of quality management,standardization of procedures,result validation and interpretation is implemented in the routine work,the clinical significance of body fluid cytological analysis can be recognized in clinical practice.

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 approach the efficacy and safety of arotinolol in treating essential hypertension.Methods The studies about arotinolol in treating essential hypertension were accessed by searching the Cochrane Central Register of Controlled Trials(Issue 3,2008),MEDLINE(1991 to March 2009),EMbase(1991 to March 2009),CBMdisc(1991 to March 2009),and CNKI(1994 to March 2009).The relevant journals and conference proceedings also hand searched.Randomized controlled trials(RCTs) in which arotinolol was used to treat patients with essential hypertension were collected.Then the retrieved studies according to predefined inclusion and exclusion criteria were screened,the quality of included studies was evaluated,and Meta analysis was performed by using RevMan 4.2 software.Results A total of 176 articles were found and 6 of which were finally included.In homogeneity test:?2=4.41,df=7,P=0.73(efficacy);?2=2.96,df=4,P=0.56(safety).In combined test,Z=0.64(P=0.52),OR=1.17,OR95%CI(0.72-1.85)(efficacy);Z=1.75(P=0.08),OR=0.60,OR95%CI(0.34-1.06)(safety).Conclusion There is no significant difference in efficacy and safety between arotinolol and control group in treating essential hypertension.

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.

In order to investigate the nutritional composition of the diet taken by diabetic patients during treatment, a dietary survey of 256 outpatients with diabetes mellitus at 4 hospitals in Beijing was completed in 1980. The results of this survey may be used as a reference in designing the reasonable diets for Chinese patients of diabetes mellitus.

Objective To study the relationship between overweight, obesity and blood pressure among children living in urban Beijing. Methods A total of 4 267 pupils aged 9～10 years were randomly selected. Overweight and obesity were defined by age and sex specific BMI classification reference for Chinese children. Hypertension was defined by age, sex and height specific reference for US children. Results The prevalence of overweight and obesity in boys was 19.4% and 21.2%, in girls was 10.9% and 12.1%, respectively. Mean levels of systolic blood pressure (SBP) and diastolic blood pressure (DBP) have significant different between all study group. The total prevalence of high blood pressure (HBP) was 16.1% for boys and 15.2% for girls, while it was 36.4% and 41.3% among obese boys and girls, respectively. The prevalence of high systolic blood pressure (HSBP), high diastolic blood pressure (HDBP)and HBP gradually increased as weight increased. Compared with the normal weight group, OR(95%CI) for HBP of overweight and obese children were 2.6 (2.1～3.3) and 5.8 (4.7～7.0), respectively. Conclusion Obesity is positive correlation with hypertension in children aged 9～10years of Beijing, and the risk of hypertension was increased with their body weight.

BACKGROUND: Modern neuroradiological imaging techniques such as CT, MRI, and ultrasound help clinicians idenitify the location and volume of an infarct at present. At present, a widely available and easy laboratory examination for acute cerebral infarction is absent.OBJECTIVE: To investigate the relationship between the content S100-β in serum and infarct volume, and prognosis in patients with acute cerebral infarction.DESIGN: Case-control study.SETTING:Department of Neurology of Shandong Provincial Hospital of Shandong University.PARTICIPANTS: From September 2004 to August 2005, 58 patients with acute ischemic brain infarction less than 24 hours after symptom onset were hospitalized in the Department of Neurology of Shandong Provincial Hospital for evaluation and management and enrolled in case group. With the age of 36-86 years and a mean of (68±14) years. 21 were female and 37 were male. Included criteria: The diagnostic criteria was consistent with that of the Second China Cerebrovascular Disease Conference. Every patient who participated in the study underwent the examination of MRI or CT of the brain on admission, the patients were confirmed to be ones with cerebral infarction. Exclusion criteria: A history of a previous stroke and/or existing disability. 50 healthy participants in the control group were from Health Examination Center, including 32 male and 18 female aged 43-89 years and a mean of (68±9) years. Age means and gender were not significantly different between the case group and the control group (P＞0.05).METHODS:① Venous blood samples (2 mL) were drawn in case group at baseline, 1, 2, 3, 4, 6 and 10 days after symptom onset, and the same agent of samples were drawn in control group only at baseline. Enzymelinked immunosorbent assay was used for S100-β measurement. ② Infarct volume of patient was measured by Simes Somatom sensation cardiac wizard workstation volume for CT on day 7 after symptom onset. Neurological outcome was assessed at 3 months after the onset of symptom with modified Rankin scale (MRS) score.MAIN OUTCOME MEASURES: ① Level of S100-β in serum of the subject in the two groups. ② Final infarct volume of patients in case group on day 7 after symptom onset and functional outcome 3 months after symptom onset.RESULTS: 58 patients and 50 healthy control subjects were enrolled in the study. 6 patients in case group developed complete loss of brain stem reflexes and died within 2 months. The others entered the result analysis.①The level of S100-β protein: The level of S100-β protein increased gradually in the case group, peaked at day 3 [(0.61±0.13) μg/L], and decreased at day 10. The levels of S100-β in 6 days after symptom onset were significantly higher than that in control group. The level of S100-β at day 10 in the case group was similar with the control group. ② The level of serum S100-β content in patients of case group: The serum S100-β content were obviously correlated with the infarct volume at 1, 2, 3, 4, 6days after the symptom onset. S100-β value at day 3 provided the highest correlation coefficients (r=0.937, P ＜ 0.001) ③ The status of the cerebral infarction of patients after 3 months: S100-βmeasures and the MRS scores that were obtained 3 months after cerebral infarction revealed highly significant coefficients ranging by bivariate correlations (r=0.507, P ＜ 0.01).CONCLUSION: The content S100-β in serum and infarct volume of the patients with acute cerebral infarction revealed positive correlation. The content S100-β in serum can help to calculate neurological outcome of patients after acute cerebral infarction.
