Hyperhomocysteinemia is an important independent risk factor for cardio-cerebrovas- cular diseases.Studies in recent years have suggested that hyperhomocysteinemia is also an independent risk factor for vascular dementia and Alzheimer's disease.Mild vascular cognitive impairment is the prophase of vascular dementia.Mainly through the damage of vascular wall structure and its function,homocysteine may has correlation with mild vascular cognitive impairment.

Orange peel was used as lowcost adsorbent in binding of Methylene Blue.The effects of equilibrium time,pH,dye concentration have been studied.Carboxyl,amine and phosphonate functional groups were present in the orange peel.The equilibrium time was 1 hour,the maximum adsorption capacities of the orange peel was 370.3?31.0 mg/g at pH 10.The Langmuir and Freundlich isotherms were well fitted in this biosorption system.Results showed relatively higher rate constant and biosorption capacities.These adsorption performance indicate the orange peel as a potentially economical adsorbent for dye removal.

Objective To study the chemical constituents of the organic acid part from Camptosorus sibiricus.Methods The compounds were isolated by chromatography on silica gel column and identified on the basis of physicochemical constants and spectral analysis.Results Ten compounds were isolated and their structures were identified as 11,12,15-trihydroxy-13-en-octadecenoic acid(Ⅰ),caffeic acid(Ⅱ),courmaric acid(Ⅲ),protocatechuic acid(Ⅳ),4-hydroxybenzoic acid(Ⅴ),isovanillic acid(Ⅵ),2,4-dihydroxybenzoic acid(Ⅶ),cinnamic acid(Ⅷ),succinic acid(Ⅸ),palmitic acid(Ⅹ).Conclusion Compound Ⅰ is a new compound named as camptosoric acid and compounds Ⅲ-Ⅹ are obtained from the plants of Camptosorus Link for the first time.

Objective To expand the application of electrochemical immunosensor during deleting aflatoxin B1 in foods and feeds through analyzing impacts of the time of antibody incubation and sample preparation .Methods T he double self-assembly immu-nosensor combined with aflatoxin B1 and carboxylated single-walled carbon nanotubes (SWNTs) was characterized by cyclic volta-mmetry and impacts of the time of antibody incubation and sample preparation methods were investigated .Results The signal in-creased gradually following the increasing time of antibody incubation and reached a plateau at 90 min and sample preparation meth-ods showed a comparatively large impact on results .Additionally ,the crude extractions purified through removing interfering com-pounds by immunoaffinity column could effectively eliminate the interference effects of sample matrix .Conclusion Deleting aflatox-in B1 by electrochemical immunosensor is characterized by various features ,such as fast ,simple and low detection limits .The pres-ent study shows that stability of the electrochemical immunosensor is affected by the time of antibody incubation and sample prepa-ration .

OBJECTIVETo investigate therapeutic effects of vacuum sealing drainage (VSD) in the treatment of soft tissue defect combined with tendon and bone exposure.
METHODSFrom October 2007 to February 2011, 397 patients (412 feet) with open ankle fracture and dislocation combined with soft tissue defected were treated by VSD. There were 301 males and 96 females with an average age of 36 years (ranging age from 20 to 73 years). According to AO classification, 74 feet were type I, 211 feet were type II, 108 feet were type III and 19 feet were type IV. The mean time from injury to operation was 5.6 h ( 2 to 12 h). The mean treatment time of was 10 months (4 to 19 months).
RESULTSOne hundred and forty-one patients were primarily healed, 97 patients were sutured at stage II. Split-thick skin grafting was performed at stage II was performed in 103 patients; free flap transplantation was performed in 25 patients. Three of the 34 patients with infection were removed steel plate; Eviscerate flap coverage wound was performed in 14 patients caused by the first metatarsal bone exposure; Toe amputation were performed in 22 cases caused by toes necrosis. Tarsometatarasl joints perforators' surgery was performed in 10 patients with forefeet necrosis. Thirty hundred and six patients were followed up from 3 to 20 months (averaged 10 months). The wounds healed well.
CONCLUSIONVSD for soft tissue defects caused by ankle injury is a simple and effective method, but can not replace debridement and transfer flap.
