Objective To investigate the association between levels of serum alanine aminotransferase (ALT) and the risks of metabolic syndrome in middle-aged and elderly Chinese. Methods After excluding subjects with known liver disease, excess alcohol consumption and serum ALT≥40 IU/L,1 664 subjects aged 40 years or older from Baoshan Community, Shanghai were recruited to undergo questionnaire interview, anthropometric measurements, and fasting blood sampling. Biochemical features were evaluated and the metabolic syndrome was defined according to the National Cholesterol Education Program Adult Treatment Panel III (NCEP ATP III) criteria with modification on waist circumference cutoff which is more appropriate for an Asian population. Results Increased ALT levels were associated with more unfavorable metabolic risk profiles. The prevalence rates of the metabolic syndrome in participants with increasing ALT quartiles were 29. 2% , 38. 0% , 44.9% , and 62. 9% , respectively (P for trend <0. 01 ). ALT concentrations were significantly elevated with increasing number of the metabolic syndrome components (P for trend<0.01). Serum ALT levels were significantly associated with the risks of metabolic syndrome and most of its components in a dose-response manner. As compared with participants in the first ALT quartile, the risks of metabolic syndrome were increased by 146% , central obesity by 204% , hypertension by 35% , high triglycerides by 133% , and hyperglycemia by 72% in participants of the fourth ALT quartile. Conclusions A high-normal serum ALT level was significantly associated with an increased risk of the metabolic syndrome in middle-aged and elderly Chinese.

OBJECTIVETo investigate the regulation trend of Jinxin Oral Liquid (JXOL) on the expression of negative regulatory factor of TLR3 signaling pathway SOCS1 in the lung tissue of RSV infected BALB/c mice at different time points.

METHODSTotally 75 BALB/c mice were randomly divided into 5 groups, i.e., the normal control group, the model group, the ribavirin group, the high dose JXOL group, and the equivalent dose JXOL group, 15 in each group. Each group had 3 intervention ways (I, II, and III) with 5 mice treated in each group. BALB/c mice were nasally infected with respiratory syncytial virus (RSV), and treated by different intervention ways. After intervention, mice were killed and their lung tissues were sampled, mRNA expression levels of RSV-M, SOCS1, and IFN-β were detected by Real time PCR. The expression of SOCSl at the protein level was detected by Western blot.

RESULTSCompared with the normal control group, the mRNA expression level of SOCS1 and IFN-β, and the protein expression level of SOCS1 increased significantly in the model group intervened by intervention I and II (all P < 0.01), but the mRNA expression level of IFN-β decreased significantly in model group intervened by intervention III (P < 0.01). Compared with the model group, the mRNA expression level of RSV-M all significantly decreased in the high dose JXOL group and the equivalent dose JXOL group intervened by 3 intervention ways (all P < 0.01). The mRNA expression level of SOCS1 significantly decreased in the high dose JXOL group intervened by intervention I and III and the equivalent dose JXOL group intervened by 3 intervention ways (all P < 0.01). The mRNA expression level of IFN-β significantly decreased in the high dose JXOL group intervened by intervention I and II and the equivalent dose JXOL group intervened by intervention I (all P < 0.01), while it significantly increased in the high dose JXOL group intervened by intervention III and the equivalent dose JXOL group intervened by intervention III (all P < 0.01). The protein expression level of SOCS1 significantly decreased in the high dose JXOL group intervened by intervention I and the equivalent dose JXOL group intervened by 3 intervention ways (all P < 0.01), while it significantly increased in the high dose JXOL group intervened by intervention III (all P < 0.01). Compared with the high dose JXOL group, the mRNA expression level of RSV-M decreased significantly in the equivalent dose JXOL group intervened by intervention I and II (P < 0.01). The mRNA expression level of SOCS1 and IFN-β decreased significantly in the equivalent dose JXOL group intervened by intervention I (P < 0.01), but the mRNA expression level of IFN-β increased significantly in the equivalent dose JXOL group intervened by intervention II and III (all P < 0.01). The protein expression level of SOCS1 decreased significantly in the equivalent dose JXOL group intervened by 3 intervention ways (all P < 0.01).

CONCLUSIONSJXOL could inhibit the expression of SOCS1 in the lung tissue of RSV infected BALB/c mice at different time points. Its regulatory effect might be associated with promoting the expression of interferon type I and further fighting against RSV.

Objective To investigate the role of intercellular adhesion molecule-1 (ICAM-1) in the up-regulation of peripheral blood somatic stem cells after acute myocardial infarction in rats. Methods The models of acute myocardial infarction were established in 16 rata by ligation of left anterior descending branch of left coronary artery through chest incision, and the animal were divided into control group(n=8) and experiment group (n=8). The hearts of another 2 rats were obtained for normal myocardial tissue sections as controls. Monoclonal antibody of ICAM-1 was infused from the caudal vein in experimental group, and no invervention was conducted for control group. Blood samples were obtained from caudal vein on the first, third, seventh and fourteenth day after operation in these two groups. Serum concentration of ICAM-1 was measured by ELISA, positive rate of CD34 cells in peripheral blood was detected by flow cytometry, and the parameters of concentration of ICAM-1 and positive rate of CD34 cells at each time point were compared between groups. Results The concentration of ICAM-1 in peripheral blood of experiment group reached the lowest of (59.01±2.22) pg/mL on the seventh day. The concentrations of ICAM-1 in peripheral blood of experiment group were lower than those in control group, and there were significant differences between these two groups on the seventh and fourteenth day(P < 0.01). The positive rate of CD34 cells in peripheral blood of experiment group reached the highest of (12±2.11)% on the seventh day. The positive rates of CD34 cells in peripheral blood of experiment group were higher than those in control group, and there were significant differences between these two groups on the third, seventh and fourteenth day(P<0.05 or P<0.01). Conclusion ICAM-1 can inhibit the up-regulation of peripheral blood somatic stem cells after acute myocardial infarction in rats.

Objective To test synchronization of cardiac mechanical contraction by means of advanced echocardiography and investigate the correlation of left ventricular ejection fraction (LVEF) and the indexes of mechanical dyssynchrony, and the relationship between DTI, STI and RT-3DE.Methods Control group (20 cases), chronic heart failure with a widened QRS complex (12 cases) and chronic heart failure with a shortened QRS duration (10 cases) were selected.
