[ ABSTRACT ] AIM: To investigate the effect of catalpol on the activity of osteoblasts ( OB ) and osteoclasts ( OC) , and OB estrogen receptor ( ER) α/βmRNA expression in the OB-OC co-culture system.METHODS: OB and OC were isolated from the SD rats of 1 and 5 days old.In the OB-OC co-culture system, different concentrations of catalpol including low dosage (0.05 , 0.1, 0.5 and 1 mg/L), middle dosage (2, 5 and 10 mg/L), and high dosage (20, 50 and 100 mg/L) were added into the culture medium to detect the changes of OB proliferation by MTT assay.The catalpol at maximal dosage was added to OB section to detect the alkaline phosphatase ( ALP) activity of OB by pNPP method.The mRNA expression of ERα/βin the OB treated with catalpol in the co-culture system was detected by RT-PCR.The catalpol at maximal dosage was added to OC group to detect the activity of OC by microscopy and tartrate-resistantacid phosphatase ( TRAP) activity detection.RESULTS:In 0.05~2 mg/L catalpol groups, the proliferation of OB was significantly in-creased as compared with control group in the co-culture system, and it reached the maximum value when catalpol was at 0.05 mg/L, while in 5~100 mg/L catalpol groups, the proliferation of OB was not increased.The ALP activity of OB in 0.05 mg/L catalpol group was higher than that in control group.The catalpal at 0.05 mg/L promoted the mRNA expression of ERβin OB in the co-culture system, but did not increase the mRNA expression of ERαas compared with control group. Catalpol at 0.05 mg/L obviously inhibited the bone resorption and the TRAP activity in OC.CONCLUSION: Catalpol stimulates the proliferation and activity of OB, inhibits the bone resorption and activity of OC, and increases the mRNA ex-pression of ERβin OB in the OB-OC co-culture system, suggesting that high mRNA expression of ERβmay be the regula-tory pathway of catalpol in response to bone metabolism.

Objective To explore the correlation of PAI-1 and TNF-α and the pathophysiology of the metabolic syndrome (MS) and coronary heart disease,and explore the role of metformin in the MS.Methods Sixty cases of old patients with the MS were chosen.These patients were divided into two groups at random.One group interfered with living style and metformin,the other group only interfered with living style.The activity of PAI-1 was detected by chromogenic substrate method,and the level of TNF-α was detected by ELISA assay.Results (1) The levels of PAI-1 and TNF-α in the MS patients [(0.95 ± 0.05) AU/ml,(24.81 ± 3.87)ng/ml] were significantly higher than in normal old people[(0.66 ± 0.10)AU/ml,(10.76 ±2.00) ng/ml] (P <0.001) ;(2)The levels of PAI-1 and TNF-α in the MS patients with CHD [(0.96 ± 0.05) AU/ml,(26.12 ± 2.83) ng/ml] were significantly higher than those in the patients without CHD [(0.94 ± 0.03) AU/ml,(23.71 ± 4.27) ng/ml] (P < 0.05) ;(3)The activity of PAI-1 and the level of TNF-α in the metformin group was decreased significantly [△ was (0.20 ± 0.17)AU/ml,(4.42 ± 0.85ng/ml),P <0.01],and metformin can improve the components of the MS.Conclusions The old patients with MS is prone to develop cardiac vascular disease.PAI-1 and TNF-α participate in pathophysiology of the MS and its complication.Metformin can inhibit the expression of PAI-1 and TNF-α to suppress the components of the MS,and block the complication of the MS.

OBJECTIVETo construct a humulus pollen allergy DNA vaccine pcDNA3.1-Hum and investigate its effect for immune protection mediated by Foxp3(+)Treg cells in asthmatic mice.
METHODSThe target humulus gene obtained from pTripIEx2-Hum plasmid by double enzyme digestion was inserted sequentially into pcDNA3.1(-) vector to generate the recombinant plasmid pcDNA3.1-Hum, which was validated by sequencing. The pcDNA3.1-Hum plasmid was transfected into COS-7 cells and the expression of the ectopic protein was analyzed using Western blotting. Co-cultured dendritic cells and CD4(+)CD25(-) T cells were stimulated with the expressed protein to test its efficacy in inducing Foxp3(+)Treg cells. The levels of humulus-specific IgE and IgG2a were assayed to evaluate the allergenicity and immunogenicity of pcDNA3.1-Hum in mice. The immunoprotective effect of pcDNA3.1-Hum was assessed in a mouse model of humulus-specific asthma.
RESULTSThe constructed pcDNA3.1-Hum plasmid was validated by sequencing and Western blotting, and the expressed protein was shown to induce Foxp3(+)Treg cells in the co-culture. In normal mice, pcDNA3.1-Hum induced a significant increase of humulus-specific IgG2a but had no effect on IgE. In the asthmatic mice, pcDNA3.1-Hum significantly decreased inflammatory cell counts and eosinophil percentages in the BALF, ameliorated lung inflammation, and lowered AHR and IL-4 levels; immunization of the mice with pcDNA3.1-Hum reversed humulus-induced reduction of serum IFN-γ and prevented the humulus-triggered reduction of Foxp3(+)Treg cell percentage in the spleen.
CONCLUSIONWe have successfully constructed a highly immunogenic pcDNA3.1-Hum DNA vaccine that can mediate immune protection by inducing Foxp3(+)Treg cells.

OBJECTIVETo examine the correlation of the changes in the serum markers (C-reactive protein, endothelin-1, interleukin-6, and brain natriuretic peptide) with chronic obstructive pulmonary disease (COPD) and pulmonary hypertension secondary to COPD.
METHODSA total of 174 COPD patients with acute exacerbation, admitted between February 2011 and February, 2013, were enrolled in this study, with 43 volunteers with normal pulmonary functions as controls. Pulmonary arterial pressure was determined by Doppler echocardiograph, and the severities (mild, moderate and severe) of PH secondary to COPD was evaluated. The levels of serum markers were determined using ELISA kits.
RESULTSThe levels of serum markers in patients with COPD was significantly elevated compared with those of the control subjects (P<0.05), and further increased in patients with pulmonary hypertension secondary to COPD (P<0.05). A positive correlation was found between these serum markers and pulmonary artery pressure in COPD patients with mild and moderate pulmonary hypertension. In patients with severe pulmonary hypertension, only the serum level of brain natriuretic peptide continued to increase with pulmonary artery pressure (P<0.05), and the other markers did not further increase.
CONCLUSIONSEarly and combined examination of these serum markers in patients with COPD can help to identify pulmonary hypertension in early stage and estimate the severity of pulmonary hypertension. Hemodynamic monitoring of the changes of these serum markers can be of important clinical value in the treatment of pulmonary hypertension secondary to COPD and in evaluation of the prognosis of COPD.

OBJECTIVETo systematically review whether statins can reduce the risk of infection and infection-related mortality.
METHODSWe searched the Cochrane Library, MEDLINE, EMBASE, PubMed, Elsevier and CBM databases for randomized placebo-controlled trials of statins published by September 2013, and each trial enrolled at least 100 participants with follow-up for at least 4 weeks. Two reviewers independently assessed the quality of the included studies and extracted the relevant data for analysis using Stata 12.0 software.
RESULTSSixteen trails involving a total of 48973 patients were included in our meta-analysis. The results showed that statins significantly reduced the risk of infection (OR=0.93, 95% CI 0.89 to 0.98, P=0.004) compared to placebo but did not significantly lower infection-related mortality (OR=0.96, 95% CI 0.82 to 1.12, P=0.592).
CONCLUSIONStatins can significantly reduce the risk of infection but does not lower infection-related mortality.
