Objective To explore the relationship of serum homocysteine ( Hcy) level with metabolic syndrome (MS) and its components.Methods A cross-sectional study was conducted in 594 adults consec-utively sampled from people visiting Fuwai Hospital for physical examination between September and Decem-ber 2012, including 160 MS participants (MS group) and 434 without MS participancs (without MS group). Serum Hcy levels, serum biochemical parameters, and anthropometric measurements of all the participants were collected.Binary logistic regression was used to assess the association of serum Hcy levels with MS and its components.Results No significant difference in Hcy levels was observed comparing the MS group and the without MS group [(12.2 ±7.0) μmol/L vs.(12.6 ±8.4) μmol/L, P>0.05].Between participants with and without hyperhomocysteinemia (≥15 μmol/L vs.<15 μmol/L) , no statistically significant differ-ences were observed in prevalence of MS and its metabolic disorders ( MS 27.3% vs.26.9%; high blood pressure 27.3% vs.19.6%; high triglycerides 50.0% vs.48.3%; high-density lipoprotein cholesterol 39.8%vs.36.6%; dysglycemia 30.7% vs.32.6%; abdominal obesity 31.8% vs.31.2%; all P >0.05).Among participants having 0 to 5 metabolic abnormalities, there were no significant differences in ser-um Hcy levels [ (12.3 ±7.4) μmol/L; (12.4 ±6.7) μmol/L; (13.2 ±11.2) μmol/L; (12.5 ± 7.8) μmol/L; (11.2 ±2.7) μmol/L; (12.4 ±4.3) μmol/L; all P>0.05].In a binary logistic re-gression model adjusted for age, gender, body mass index, total cholesterol, low-density lipoprotein choles-terol, and high-sensitivity C-reactive protein, neither MS nor its components were independent predictors of serum Hcy levels ( all P>0.05 ) .Conclusions Elevated serum Hcy levels are not associated with MS or its components in people without evident cardiovascular diseases .MS and elevated serum Hcy levels may cause cardiovascular diseases via different mechanisms .

In order to produce valuable monoclonal antibodies for immunodiagnosis of cysticerco-sis, hybridoma technique was adopted using the fusion of splenic lymphocytes from BALB/c mice immunized with Cysticercus cellulosae antigens and the myeloma cell line NS-1. Through screening and cloning, three monoclonal antibody cell lines have been established. Im- munoglobulin subclasses of 3 lines were determined to be IgGl. These monoclonal antibodies were found to be highly specific and without cross reaction with Echinococcus granulosus hy-datid cyst and Cysticercus fasciolasis. Antigen fractions specifically reacting to monoclonal antibodies were demonstrated with Western blot method. The results showed that specific reaction bands of SCW located in 25 kDa and 17 kDa regions.

Objective To investigate the effects of temporary hepatic inflow occlusion (HIO) on hepatic energy metabolism of rats with liver cirrhosis. Methods Animal survival rate and hepatic energy metabolism were observed following different periods of HIO with the effect of portal vein blood bypass (PBB) and without PBB, including repiratory controa ratio (RCR), adenosine tirphosphate (ATP), and arterial blood ketone body ratio (AKBR). The sham group served as the control. Results ATP, RCR and AKBR decreased significantly ischemia (P

Objective To approach the relationship between the membrane protein of platelet microparticles and myocardial infarction or hypertension. Methods The contents were examined of PAC-1~ + PMP and CD62P~+ PMP by activating platelet with 20?mol/L ADP in the blood collected from the patients with myocardial infarction (n=12) and hypertension (n=10). Results The contents of PAC-1~ + PMP and CD62P~+ PMP in myocardial infarction group (85.1%?3.7%, 85.9%?3.8%) were significantly higher than normal group (75.5%?4.4%, 76.3% 5.3%) (P

Objective To better understand the regulation of the soluble receptor of vascular endothelial growth factor (VEGF), s-VEGFR-1 (or soluble fms-like tyrosine kinase, SFlt-1), in angiogenetic process in endometriosis. Methods Levels of free VEGF and s-VEGFR-1 were measured by enzyme-linked immunosorbent assay (ELISA) in peritoneal fluid from 28 subjects with surgically confirmed endometriosis, and 10 controls with no clinical evidence of the disease and other diseases. Meanwhile, we calculated a VEGF activity index by means of the ratio VEGF/s-VEGFR-1. Results We found higher VEGF concentration in endometriotic lesions than controls (P0.05). VEGF activity index in controls, stage Ⅰ-Ⅱ and stages Ⅲ-Ⅳ of endometriosis was 0.310, 0.276 and 0.273, respectively. VEGF and s-VEGFR-1 concentration were also higher in proliferative phase than in secretory phase in endometriotic lesions (P

Objective To observe the effect of Isoket on standard dobutamine stress echocardiography(DSE).Methods Thirty-seven patients were divided into three groups according to the results of quantitative coronary angiography(QCA):the control group(CON) including 12 patiens,the coronary artery disease group 1(CAD1) including 15 patients,and the coronary artery disease group 2(CAD2) including 10 patients.Among the three group,the DSE+Isoket was done in CAD2,while the standard DSE was done in the other two groups.The improvement of segments of left ventricular after percutaneous transluminal intervention(PCI) was looked as the standard evaluating DSE.Results Isoket could increase heart rate and decrease systolic blood pressure,but could hardly affect diastolic blood pressure.The rate of biphysic response was 62.5% in group CAD1,and the sensitivity of detecting viable myocardium was 61%,while the specificity was 76%.In group CAD2,the rate of biaphysic response was 72.2% ,and the sensitivity of detecting viable myocardium was 82%,while the specificity was 88%.The rate detecting viable myocardium and sensitivity was improved significantly in group CAD2.Conclusions DSE combined with Isoket was beneficial for detecting viable myocardium.

Objective To evaluate the effect of azithromycin on mycoplasmal pneumonia (MP).Methods We divided 90 MP cases into azithromycin and erythromycin treatment groups. In azithromycinThe pyretolysis time, cough improvement time, the disappearing time and the mean length of hospitalization of azithromycin group were shorter than that of erythrornycin group. The local ache, stomach and intestinal tract adverse reaction, and damage of hepar function were less than these in erythromycin group. ConclusionAzithromycin is an effective and safe drug to MP.

Objective Human cytomegalovirus (HCMV) can induce infection in multiple organs, including genitouri-nary system, central nervous system and liver. It can even lead to serious defects and death. China, as a high-incidence area of HCMV, need employ early treatment. However, the sensitivity of present HCMV diagnosis is not satisfied. Methods In the present study, we focused on transcription level of HCMV IE and pp67 mRNA using real-time quantitative PCR. Results IE mRNA was positive even in a portion of patients who were regarded as negative by traditional DNA diagnosis method. On the other hand, pp67 mRNA that were normally expressed at the late stage of HCMV infection was 100%posi-tive in the first-visit patients who were regarded as positive using traditional DNA diagnosis method. Conclusion The pres-ent study indicated that mRNA detection based on PCR method was more sensitive compared with DNA detection for assess-ing HCMV virus infection. Finally, different treatment should be performed upon mRNA transcription profile at different in-fection stages.
