Objective To study the effects of different types of ankle brace on human body static postural stability.Method Ten male subjects with unilateral functional ankle instability (FAI)were enrolled in the study.The FlexiForce pressure control system was used to control the pressure on the ankles when wearing the soft brace.The static postural stability without braces as well as with soft and semi-rigid braces was measured using WIN-POD system.Results (1)In eye-open testing,no significant difference was found in indexes of COP sway between wearing or not wearing braces (P＞0.05).Compared with wearing semi-rigid brace,significant increase was observed in the average X dev when wearing soft braces (P＜0.05).(2)In eye-close testing,no significant differences were found in COP sway either wearing braces or not,as well as wearing different braces.Conclusion Wearing soft and semi-rigid brace had no effects on the static postural stability of FAI patients.But the static balance ability of wearing semi-rigid braces is better than that of wearing soft braces.

Objective To explore the effect of aspirin resistance on cardiovascular events in non-insulin-dependent diabetes melli-tus patients .Methods 496 patients with non-insulin-dependent diabetes mellitus received daily aspirin therapy (100mg/d) 4 weeks were recruited from Jun .2006 to Sept .2010 .Platelet aggregation was measured by light transmission aggregometry .The patients were divided into three groups :aspirin resistance group ,aspirin semi-resistance group and aspirin-sensitive group .The clinical bio-chemistry indications and the adverse cardiovascular events were collected .Results 11 .69% of patients were found to be resistant to aspirin therapy ,and 37 .90% of patients to be aspirin semi-responders .There were 67 .48% female in aspirin resistance group and aspirin semi-responders .The preprandial glucose of group AR and ASR was higher than that of group AS (P<0 .05) .The HbA1C and TG of group AR were higher than those of group AS(P<0 .05) .There was statistically significant difference of the rate of car-diovascular events .Conclusion The measure of platelet aggregation should be taken in the diabetic mellitus patients and pay atten-tion on the dose of aspirin recommended .Particular attention is should also devote to the incidence of adverse cardiovascular events .

Neurally ajd usted ventilatory assist( NAVA) uses the electrical activity of the diaphragm as a neural trigger to synchronize mechanical ventilatory breaths with the patient′s neural respiratory drive. Some studies have shown that compared with pressure-support ventilation,NAVA can improve patient-venti-lator synchrony while maintaining spontaneous breathing,unload respiratory musculaturei n term adn prte erm i nfants.Further studies are needed to determ ine whether NA VA will have significant impact on the overall outcomes of neonates.

Food allergy( FA) is a growing health problem which affects young children′s growth. Re-cent studies have showed that leukotrienes can contract gastrointestinal smooth muscle,increase intestinal perm-bility,and it is obviously related to the development of FA gastrointestinal disorder. Leukotriene receptor antago-nists have provided a good therapeutic option and showed clinical benefits in the management of the FA gastroin-testinal disorder.

The US federal government regards health information technology (HIT) as an important action to stimulate growth of the health information economy.To implement HIT,the federal government proposed a tiered plan from organization guarantee,institutional innovation,HIT system design to economy stimulating mechanism,and to health care providers as well.In view of China's HIT development,it is proposed that HIT must proceed with healthcare reform in parallel.Stage-setup by the government,competition among enterprises,and active role of medical service providers constitute fundamental guarantee to ensure HIT go on wheels.Electronic health records of individuals should play key roles in promoting pragmatic and shared medicine health care information system.

Objective　To establish a simple assay for quick scanning of effective agents in growth inhibition and apoptosis induction. Methods　After observing the correlation between cell number and acid phosphatase activity, and between cell apoptosis and acid phosphatase activity, we established a microplate densimetry method to measure the acid phosphatase activity. We also compared the sensitivity with MTT assay and confirmed cell apoptosis by flow cytometry. Results　In two cell lines of cancer (Hep G2 and CBRH-7919 cells), the acid phosphatase activity was correlated well with the cell number, and was directly proportional to the cell number in the range of 0.5×103～0.7×103. The coefficient reached to 0.994. After stimulation of phorbel ester (TPA) for one hour, the acid phosphatase activity rose significantly. In contrast, after the inhibition of cell growth by As2O3, the acid phosphatase activity decreased significantly. The higher the concentration of As2O3, the lower the acid phophatase activity. The acid phophatase activity went down significantly when apoptosis in Hep G2 cells was only 3.98% and no apoptosis in CBRH-7919 cells after 24-hour treatment with As2O3. Conclusions　The acid phophatase activity of cell may be used to measure cell proliferation and apoptosis. Because of the easiness and quickness, acid phophatase assay might be an ideal approach to scan the effective growth inhibitors and apoptosis inducers in a large number of drugs.

Objective To discuss the clinical val ue of internal radiation therapy with hepatic intra-arterial iodine-131 labele d material for the treatment of hepatocellular carcinoma (HCC). Methods This summarized paper was made on literatu re review. Results Iodine-131-lipiodol and several reported iodine-131-labeled antibodies to HCC associated antigens were concentrated in the foci of HCC with a high tumor-to-normal-tissue absorbed dose ratios. No s evere side effects occurred. It was used in various kinds of HCC patients, and m ostly showed a significant tumor response. Survival rate of HCC patients was rai sed in several clinical trials.Conclusion Internal radiotherapy with hepatic intr a-arterial iodine-131 labeled material may be considered as an effective metho d to treat HCC.

Objective To evaluate CT features of hemorrhagic and necrotic polyps of maxillary sinus and nasal cavity.Methods Twenty-nine cases of hemorrhagic and necrotic polyps proved pathologically were collected in this study.Axial,coronal,plain and / or contrast enhanced thin-slice CT scans were performed in all the cases.Results The density of lesion was inhomogene (26/29).The lesions had clear boundary and slight enhancement on contrast-enhanced scan.Expanding of nasal and /or antronasal cavity,compressive bony absorption were often seen in inter-wall of maxillary sinus(13/29).The bony destruction in most of the cases were showed with bony sclerosis(25/29).Conclusion The diagnosis of hemorrhagic and necrotic polyps can be confirmed by CT examination.

Objective: To investigate the effect of simvastatin on the expression of vascular endothelial growth factor (VEGF) in rabbit aortic atherosclerotic plaques. Methods :Twenty rabbit aortic atherosclerotic models developed by hyper-lipidemic and hypercholesterol feeding were randomly divided into simvastatin treated group (n = 10) and hyperlipidemic diet group (n = 6); another 8 commonly fed rabbits were taken as control group. VEGF protein levels in atherosclerotic plaques were studied by immunohistochemistry. Results: Positive signal of VEGF in simvastatin treated group and hyperlipidemic group were significantly higher than that in control group(P
