Objective To explore the effect of aerobic exercise on platelet function in elderly patients with hypertension and type 2 diabetes.Methods81 elderly patients with hypertension and type 2 diabetes were divided into the routine treatment group (group A, n=41) and regular exercise group (group B, n=40). All patients of two groups were treated with routine treatment. The exercise with moderate intensity was performed in the group B for 3 months besides routine treatment. The platelet membrane glycoprotein CD62P, CD61 (Ⅲa) were detected by flow cytometric analysis and platelet aggregating ratio was measured before and after regular aerobic exercise.ResultsAfter three months, the systolic blood pressures were 166±3.6 mm Hg (group A) and 152±3.5 mm Hg (group B); the diastolic blood pressures were 93±4.2 mm Hg (group A) and 83±4.3 mm Hg (group B); the contents of blood glucose were 7.4±2.4 mmol/L (group A) and 6.3±1.9 mmol/L (group B); the positive percents of platelet membrane glycoproten CD62P were 27.3±2.2% (group A) and 21.5±3.3% (group B), CD61(Ⅲa) were 26.3±2.3% (group A) and 20.2±2.9% (group B) and platelet aggregation rates were 78.4±4.5% (group A) and 69.7±5.4% (group B), there was a significant difference between two groups ( P<0.05～0.01).ConclusionRegular aerobic exercise can decrease the positive percent of platelet membrane glycoprotein and platelet aggregation rate in elderly patients with hypertension and type 2 diabetes.

Objective:To create a large human phage antibody library from which easy to get diabody and select human antibody clones.Methods:VL and VH genes were amplified by RT-PCR from RNA which came from normal adult peripheral blood and new-born cord blood lymphocytes. VL and VH genes were reamplified to add a region of overlap in the ScFv linker to form ScFv genes in which VH genes were flanked by two non-homologous loxp sites. The ScFv genes were cloned into PDF to obtain a primary library. This primary library was used to infect bacteria Bs1365(expressing cre recombinase) with high multiplicity of infection(MOI) 200∶1. This procedure resulted in a very large phage antibody library through VL and VH recombined by the cre recombinase. Following recombination, phagemide were derived from these bacteria and used to infect bacteria not expressing cre(XL1-Blue) at MOI

Objective To investigate the effects of the fibrin-derived peptide Bβ15-42 (FgBβ 15-42) on renal inflammation in acute kidney injury (AKI) induced by renal ischemia reperfusion (IR).Methods SD rats were randomly divided into sham group (the abdominal cavity were closed after separating the renal artery),IRI group (renal arteries of rats were occluded with microvascular clamps for 60 min),negative treated group (rats were injected with 3.6 mg/kg random peptide by tail vein) and FgBβ15-42 treated group (rats were injected with 3.6 mg/kg FgBβ15-42 by tail vein).Rats were sacrificed at 24 h or 48 h after reperfusion.Blood and kidney samples were collected and histological changes and renal function were examed.The mRNA and protein expressions of intercellular cell adhesion molecule-1 (ICAM-1) and interleukin-1β (IL-1β) were examined by immunohistochemistry,real-time PCR and Western blotting.Results Compared with sham group,Scr and BUN were obviously increased in IRI group (all P ＜ 0.05),pathologic changes of kidney were more serious (P ＜ 0.05).Compared with IRI group,in FgBβ15-42 treated group Scr and BUN were obviously decreased (all P ＜ 0.05),the injury of kidney tubulointerstitial was less serious (P ＜ 0.05).Compared with sham group,there was increased ICAM-1 and IL-1β in IRI group (all P ＜ 0.05),and they all peaked at 24 h.After treated with FgBβ15-42,the expression of ICAM-1,IL-1β were significantly decreased in kidneys compared to IRI group (all P ＜ 0.05).The above indexes had no significant differences between negative treated group and IRI group (all P ＞ 0.05).Conclusions FgBβ15-42 can protect kidneys against ischemia reperfusion injury in rats.The mechanism may be associated with down-regulated expressions of ICAM-1 and IL-1 β in the kidney.
