Objective To investigate the effect of persistent ST-segment elevation after successful direct percutanous coronary intervention (PCI) on the late phase of left ventricular (LV) systolic function in acute anterior wall myocardial infarction.Methods Serial electrocardiograms were record before PCI and 1 hour after reperfusion in 72 patients with acute anterior wall myocardial infarction. The reduction of ST-segment elevation after successful PCI more than 50% was defined as ST-segment resolution (ST reduction group). Persistent ST-segment elevation was defined as ≥50% of peak ST elevation (ST elevation group). Echocardiography was performed on 2 to 3 weeks (early phase) and 5 to 6 months(late phase)after PCI to evaluate the LV function and ventricular wall motion abnormality (VWMA). Results Fifty-three patients (74%) had early ST segment elevation resolution and 19 patients (26%) did not. The LV function and VWMA were similar in two groups during early phase. But during the late phase, ST elevation group patients had lower LVEF and higher LVEDVI, LVESVI, VWMA index compared with ST reduction group (P

microRNAs (miRNAs), a class of endogenous non-coding RNA about 22 nucleotide long, regulate gene expression at the post-transcription level by inhibiting the translation or inducing the degradation of their target mRNAs in organisms. A lot of studies reveal that miRNAs in adipose tissues are involved in adipocyte differentiation and lipid metabolism and modulated by multiple transcription factors, adipocytokines and environmental factors, which form a complex regulatory network maintaining the homeostasis of adipose tissues. The discovery of circulating miRNAs adds new elements to the regulatory network. To study the metabolic diseases such as obesity, we should keep a new insight into the complex dynamic network. In this review, we summarize the latest studies of miRNAs in adipose tissues, which might provide new strategies for the treatment of obesity and other related diseases.

Objective To investigate the expression of the genes correlated with interferon induced genes virus (MX1, OAS1, IFI44) in the peripheral blood leukocytes of patients with systemic lupus erythematosus (SLE), and to evaluate the relationships between the expression levels of these genes and diseaseactivity. Methods The clinical data of 100 SLE patients, 40 non-SLE patients with rheumatic diseases, and 40 normal controls were collected. Peripheral blood samples were collected. Total RNA was extracted and transcribed into cDNA. SYBR green dye based real-time quantitative PCR method was used to compare the expression levels (indicated as △CT value) of MX1, OAS1 and IFI44 in patients with SLE and those in the controls. Comparisons between groups were performed with ANOVA and Spearman correlations. Results ①The △CT value of MX1, OAS1 and IFI44 expression level of the SLE patients (3.4±1.8, 4.2±1.5, 8.8±2.2)was significantly higher than those of the non-SLE patients (2.4±0.4, 3.4±0.7, 5.4±2.1 ) and normal controls (2.3±1.1, 2.6±0.7, 5.2±2.0). ② The △CT value of OAS1 and IFI44 expression level of the SLE patients in severe disease was significantly higher than those of the SLE patients in mild disease and the SLE patients with stable disease. ③The ACT value of OASI and IFI44 were correlated with the SLEDAI scores (r=0.038,0.380). ④ The △CT values of MX1, OAS1 and IFI44 expression level of the SLE patients with arthritis were significantly higher than those of SLE patients without arthritis. ⑤ The △CT value of IFI44 expression level of the SLE patients with lupus nephritis (3.2±2.1,2.2±1.1) was significantly higher than that of the SLE patients without lupus nephritis. ⑥ There was correlations among these genes in SLE patients (P<0.05). Conclusion The value of MX1, OAS1 and FFF44 expression level of SLE patients is up-regulated. The real time expression levels of OAS1, IFI44 genes are associated with SLE disease activity and there are close correlation among these genes with interferon induce virus-relationed genes (MX1, OAS1, IFI44) in SLE patients.
