Objective To establish relative quantification in real time reverse transcription polymerase chain reaction to measure cytokine expression.Methods TNF? and GAPDH were used as target gene and internal reference respectively. Two gene fragment were cloned, vectors were purified and quantificated. Standard curves were established using a series dilution of quantificated plasmids to measure the amplification efficiency of TNF? and GAPDH. By changing reaction conditions, the amplification efficiency of two gene were nearly 100%. Ct value of TNF? and GAPDH were measured in 14 samples stimuteneously.Results The method can detected as low as 10 3 copies with the linear range was 10 3~10 9 copies, the intra assay and interassay variation was 1% and 8% respectively. TNF? increased 8 6~9 8 fold with the average 9 2 relative to untreated control group analyzed by the 2 -??Ct methods. Conclusions The method we established has fine sensitivity and reproducibility and the data analysis was simple and reliable and can be apply to any genes.

Aim To investigate the signaling basis of the biological effects of IL-6 in U937 cells. Methods We determined the effect of IL-6 on the growth and differentiation of U937 cells and the effect of IL-6 on the activation of nuclear factors in U937 cells. Results IL-6 induced macrophage differentiation of U937 cells. Differentiated cells had strengthened ANAE (acid naphthyl acetate esterase)and NBT(nitroblue tetrazolium)-reducing activities and CD54 expression was upregulated. STAT3 could be remarkably activated by IL-6 in U937 cells and STAT3 activity was dependent on dose and time course of IL-6 treatment. However, NF-IL6,NF-κ B, AP-1 and other STAT members were not activated by IL-6. Conclusion IL-6 might induce terminal differentiation of U937 cells via JAK-STAT3 pathway.

Objective To investigate the information of outpatients with acute and chronic insomnia in the department of neurology in the general hospital.Methods In the case-control study and epidemiological investigation, the sleeping information of the outpatients in Department of Neurology of Peking University Third Hospital were collected according to classification and diagnostic criteria of mental disorder in American from October 2004 to December 2004. Multiple Logistic regression was performed to analyze the associated factors for insomnia.Results Total 925 cases were investigated and divided into acute insomnia group(149 cases), chronic insomnia group (361 cases) and control group (415 cases). After adjustment for major confounders including gender, smoking, coronary artery disease, hyperlipoidemia, education and occupation, it showed that:(1) Female (OR=2.02, P=0.001), hyperplasia of prostate (OR=1.94, P=0.036), anxiety (OR=3.29, P=0.000), depression (OR=2.48, P=0.000) and leg-moving (OR=1.78, P=0.019) increased the risk of acute insomnia significantly. (2) Female(OR=2.13, P=0.000), education (OR=2.05, P=0.005;OR=2.07, P=0.003), hyperplasia of prostate (OR=1.71, P=0.023), anxiety (OR=7.42, P=0.000) and depression (OR=4.73, P=0.000) increased the risk of chronic insomnia significantly.Conclusions Female, hyperplasia of prostate, anxiety and depression are associated with acute and chronic insomnia.

Objective This study explored the protective effect of tetramethylpyrazine on myocardial ischemia/reperfusion injury via inhibiting oxidative stress. Methods Primary cultured neonatal myocytes were applied to explore the anti-ischemia/reperfusion injury property in vitro. The survival viability of myocytes was determined by MTT; enzyme activities such as lactate dehydrogenase, creatine kinase, superoxide dismutase, malondialdehyde, and nitric oxide were analyzed with assay kits; inducible nitricoxide synthase and endothelial nitric oxide synthase expressions were determined by Westernblot. Results Tetramethylpyrazine significantly improved the beating frequencies of myocytes after oxygen-glucose deprivation/reoxygenation procedure, decreased lactate dehydrogenase, creatine kinase, and malondialdehyde levels and enhanced superoxide dismutase activity.Tetramethylpyrazine also inhibited excessive production of nitric oxide through downregulating inducible nitric oxide synthase as well as upregulating endothelial nitric oxide synthase during ischemia/reperfusion injury. Conclusion Tetramethylpyrazine could significantly improve the oxidative-stress tolerance of myocytes to keep cell membrane integrity and protect the myocardial tissue of normal physiological function via an antioxidant effect and by restoring the balance between inducible nitric oxide synthase and endothelial nitric oxide synthase, while inhibiting the generation of cytotoxic concentrations of NO.

Objective To investigate the effect of over-expressed Cyr61 on the expression of extracellular matrix of human renal tubular epithelial cells(HKC), and explore the role of Cyr61 in the pathogenesis and development of autosomal dominant polycystic kidney disease(ADPKD). Methods Cyr61 gene cDNA was amplified by RT-PCR. A recombinant plasmid pcDNA3.1+ Cyr61 was constructed by cloning Cyr61 gene into pcDNA3.1. HKC cells were transfected with wild-type Cyr61 plasmid vector (pcDNA3.1+Cyr61). Then the fusion of Cyr61 gene and expression of its protein were detected by RT-PCR and Western blot. The mRNA expression of Cyr61, collagen Ⅰ, collagen Ⅳ, and laminin were determined in four groups (the untransfected cells, pcDNA3.1 transfected cells, pcDNA3.1+Cyr61 -transfected cells and cyst-lining epithelial cells) by fluorescence quantum PCR. Results The amount of Cyr61 protein in Cyr61-transfected cells and cyst-lining epithelial cells were much greater than the control. The mRNA expression of Cyr61, collagen Ⅰ, collagen Ⅳ and laminin in Cyr61-transfected cells were all amplified significantly, and the level of collagen Ⅳwas much higher than collagen I(P
