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.

Journal of Shanghai Jiaotong University(Medical Science) 2006;0(09):-
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.
4.Construction and Expression of Recombinant Wild Lipoprotein Lipase Gene Plasmid
Journal of Shanghai Jiaotong University(Medical Science) 2006;0(09):-
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.

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 ).

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.

Objective To develop a liquid chromatography-tandem mass spectrometry (LC-MS/MS) screen-ing method for 45 poisonous alkaloids in blood. Methods Identification was based on the compound’s retention time and two precursor-to-production transitions. The method involved a liquid-liquid extraction (LLE) followed by LC-MS/MS with multiple-reaction monitoring (MRM). When 1 mL of blood was ex-tracted with diethyl ether at pH=9.2 with SKF525A as the internal standard, the target compounds were an-alyzed with LC-MS/MS in the positive ionization mode. Results The target alkaloids had good linearity (r>0.995 1), both the intra-day precision and inter-day precision being less than 14.77%. The limits of detection ranged from 0.05 to 25 ng/mL in blood. Conclusion The method is selective and sensitive in detecting poisonous alkaloids with a total running time of 12 minutes; therefore it was successfully ap-plied to some actual cases of suspected alkaloids poisoning.

Objective To evaluate the effect of ImmunoCyt on the early diagnosis of bladder cancer by comparing the result of cystoscopy with that of cytology. Methods Eighty-six consecutive patients with bladder cancer (mean age,63 years) were included in this group.Among them 38 had undergone transurethral resection of superficial transitional cell carcinoma and had been followed up and 48 had hematuria.These patients were evaluated with standard cytology and ImmunoCyt test.Then all the patients underwent cystoscopy and suspected lesions were biopsied. Results Transitional cell carcinoma of bladder was confirmed pathologically in 28 cases.The sensitivity of ImmunoCyt (82%) was superior to that of cytology (39%, P
