In this study, we aim to investigate the protective effects of astragaloside on ultraviolet A (UVA)-induced photoaging in human fibroblasts and its possible mechanisms.

Diabetic microangiopathy is one of the most common chronic diabetic complications,which is associated with the genetic predispositions and environmental factors.Well-controlled blood glucose alone can not reduce the morbility or prevent the process of diabetic microangiopathy.The therapy aiming at the pathogenesis is an urgent request.The various proteins related to the development and progression of diabetic microangiopathiy were reviewed,aiming at providing the potential target for early diagnosis and efficient therapy.

Objective To assess the efficacy and safety of aspirin for type 2 diabetes mellitus(T2DM).(Methods)Electronic database searching was performed on Medline,Cochrane Library and CBM,and the data from the beginning of the database to October 2005 were included.Randomised and quasi-randomised trials concerning aspirin treatment for T2DM were selected and assessed for the methodological quality,and the extracted data were performed Meta-analysis by statistical software RevMan4.2.8. Results Fourteen randomised and quasi-randomised trials met the inclusion criteria,including 7 papers of aspirin treatment for T2DM,3 papers of aspirin treatment for cardiovascular complication of T2DM and 4 papers of aspirin treatment for type 2 diabetic retinopathy.Compared with placebo treatment,aspirin showed significant positive effects on lowering blood glucose(SMD,0.73;95%CI,(-1.11 ~-0.36;)P=0.0001).In diabetic patients,aspirin treatment was associated with a significant reduction in the total cardiovascular events(RR,0.78;95%CI,0.68 ~ 0.98;P=0.03).Aspirin treatment neither lowered(nor increased) the risk of the development of diabetic retinopathy(RR,1.02;95% CI,0.97 ~ 1.07;P=0.54).(Conclusion Aspirin treatment) can be a choice for T2DM,especially for the patients who have evidence of cardiovascular disease or have high risks for cardiovascular disease.

Objective To study the construction of recombinant wild lipoprotein lipase(LPL) gene plasmid and its expression in COS-1 cells. Methods The LPL cDNA was isolated from the human epiploon adipose tissue by means of RT-PCR.The LPL cDNA was ligated into the pcDNA3.1Zeo(+).The recombinant pcDNA3.1Zeo(+)-LPL cDNA was identified by endonucleases,PCR and DNA sequencing.COS-1 cells were transfected with the recombinant LPL gene plasmid using Lipofectamine 2000~(TM).The LPL mass in cells and the culture medium were determined by a Markit-M LPL Kit.Spectrophotometry was used to measure the LPL activity. Results The LPL gene was ligated into the pcDNA3.1Zeo(+) plasmid identified by endonucleases and PCR.The sequence of the LPL gene was the same as the sequence of the Gene Bank identified by DNA sequencing.Wild pcDNA3.1Zeo(+)-LPL(cDNA) plasmids was transformed into the COS-1 cells. Conclusion The recombinant plasmid pcDNA3.1Zeo(+)-LPL cDNA could be constructed and successfully transformed into the COS-1 cells.

All of the thrombolytic agents currently approved for use in humans are plasminogen activators, the application of which is limited by bleeding complications at vascular injury sites and plasminogen content in the thrombus. Plasmin is rapidly neutral-ized in the circulation by α2-antiplasmin and tolerated without bleeding. With the application of catheter-based delivery, the unique bio-chemical properties of plasmin make it a safe and effective direct fibrinolytics. Plasmin derivatives, including miniplasmin,Δ-plasmin and microplsmin, display more thrombolysis efficacy and better hemostatic safety in preclinical study and clinical trials. This review sum-marizes the current information on plasmin and its derivatives, including the advances on biochemical properties, preclinical and clinical trials.

0.05).The maximum relaxant forces of vitrification and fresh arteries groups were greater than the freezing group(P 0.05).The arteries of three groups began obvious relaxant responses when sodium nitroprusside was 10-7 mol/L, and nearly reached their maximal relaxant responses when sodium nitroprusside was 10-4 mol/L.CONCLUSION:The vitrification could preserve more active smooth muscle cells of arteries than the freezing method.The norepinephrine has better effect on contraction ability of artery, which preserved in the vitrification group than the freezing group;however, there is no difference in relaxation of sodium nitroferricyanide.

OBJECTIVE:To evaluate the economic effects of different doses of methylprednisolone treatment regimes on traumatic reaction in patients with cervical spondylotic myelopathy after anterior decompressive operation.METHODS:56cervical spondylotic myelopathy cases who have been subjected to anterior decompressive operation were chosen to be the sub-jects.The56cases were divided into3groups and treated with different dosage of methylprednisolone,the initial dose for group A(18cases,low dose group)was80mg;the initial dose for group B(21cases,medium dose group)was600mg and that for group C(17cases,large dose group)was1000mg,the improvement of clinical symptom of each group was observed re-spectively and the cost-effectivenesses of the three groups were compared.RESULTS:The costs of the A,B,C groups were990.00,1339.10and1886.70yuan respectively;the effectiveness rates(E)of the A,B,C groups were5.56%,14.29%and35.29%respectively;The costs for each unit of obvious effectiveness(C/E)of the A,B,C groups were178.06,93.71and53.46yuan respectively;On the basis of group A,the needed costs of group B and C were39.99and30.16yuan respectively for each obvious effectiveness unit increase(?C/?E).CONCLUSION:Compared with group A and B,the effectiveness rates of group C had a bigger increase while the needed cost for each unit of obvious effectiveness was the lowest,therefore,the dose regimen of group C is more rational.

Two hundred and forty patients with post-stroke hemiplegia, discharged from October 2009 to January 2010, were randomly divided into two groups. One hundred twenty patients received home-based rehabilitation training, another 120 patients received conventional treatment and non-specific home rehabilitation. Brunnstrom rating and Barthel index ( BI) evaluation of motor function and activities of daily living (ADL) were performed in both groups before and after training program; Hamilton anxiety scale (HAMA) , Hospital Anxiety and Depression Scale (HAD) Assessment of anxiety and depression were also performed. Results showed that the lower limb function and ADL ability in home rehabilitation group were significantly increased, the anxiety and depression were significantly improved after home rehabilitation training ( P < 0. 005 ) ; but those indicators in control group were not significantly changed ( P > 0. 05 ).
