Objective To investigate the recognition of nurses and patients on chosing daily caregivers and analyze the influencing factors. Method Totally 1,119 nurses and 1,134 patients from five first-class and two second-class hospitals in Zhuhai participated in the survey using self-designed questionnaires from April to June in 2014. Results There were significant differences between nurses and patients in all life nursing projects (P<0.001) except making beds for patients. The top three factors influencing the nurses′recognition were shortage of nursing staff and time, less presence of professional values and feeling no respects. The top three factors influencing the patients′recognition included tending to be nursed by family members, worries about medical expenses, and nurses′being too busy on treatment. Conclusion The different recognitions of nurses and patients on daily caregivers are influenced by multiple factors. Therefore , nursing managers should take some effective strategies to change the concepts of nurses and patients so as to improve quality of nursing service.

Objective To explore the visinin-like protein-1 (VILIP-1) levels in the blood in the Alzheimer disease (AD) and mild cognitive impairment (MCI) due to AD patients,and also to explore its feasibility as a biomarker for the early diagnosis of AD and for the detection of progression of AD.Methods Fifty-eighty participants were included:20 cases for AD group,19 cases for MCI due to AD group,19 cases for normal control group.The level of VILIP-1 was tested by the ELISA method.Results The level of VILIP-1 in AD group was significantly higher than that in normal control group and MCI due to AD group:(9.0 ± 2.9) ng/L vs.(3.3 ± 1.7) and (6.5 ± 3.1) ng/L,and that in MCI due to AD group was significantly higher than that in normal group,there were statistical differences (P ＜ 0.01).The MMSE score in AD group was significantly lower than that in normal group and MCI due to AD group:(15 ± 3) scores vs.(27 ± 2) and (23 ± 2) scores,and that in MCI due to AD group was significantly lower than that in normal group,there were statistical differences (P ＜ 0.01).The level of VILIP-1 was negatively correlated with MMSE score (r =0.463,P ＜ 0.01),but positively correlated with age (r =0.417,P =0.01).Conclusions With the progression of the disease,the cognitive impairment of the AD patient is decreasing.VILIP-1 increased in the blood of the patients of AD and MCI due to AD.It means that the blood VILIP-1 could be a new and potential biomarker for the early diagnosis of AD,and it may be clinical useful for the early diagnosis and effective detection of AD to some extent.

Objective To investigate the relationship between carotid atherosclerotic plaque and multiple risk factors of angiocardiopathy,and to evaluate the injuries caused by different risk factors to subclinical target organ to control the general risk factors of angiocardiopathy.Methods Four hundred and twenty six outpatients and impatients,treated in our hospital from May 2007 to May 2009 with the results of color ultrasonic examination,were divided into carotid atherosclerotic plaque group(284 cases) and no carotid atherosclerotic plaque group( 142 cases).The clinical information including their age,body mass index,smoking condition,past medical history such as hypertension,diabetes mellitus and hyperlipoidemia were recorded,and the levels of total cholesterol(T C),high density lipoprotein cholesterol( HDL-C),low density lipoprotein cholesterol(LDL-C),triglyceride (TG),lipoprotein ( a ) ( LP (a) ),apolipoprotein A - 1 ( Apo A 1 ),apolipoprotein B ( Apo B ),highsensitivity C-reactive protein( hs-CRP),homocysteine ( HCY),microalbuminuria( MAU ) and uricacid(UA) were determined by lab tests.The independent variable and univariable data were processed and analyzed statistically to find out the risk factors of carotid atherosclerotic plaque.Results Age and drinking were significantly correlated with the carotid intima-media wall thickening(IMT) (P ＜ 0.001 ).Overweight,diabetes mellitus,increased LP (a),hyperlipoidemia,age,increased MAU and HCY could independently predict carotid atherosclerosis and plaque formation ( x2 =71.35,38.45,t =3.26,x2 =37.23,t =118.51,6.723 and 3.17respectively,Ps ＜ 0.05 ).The aggregated number of the risk factors was correlated to IMT and carotid atherosclerotic plaque ( P =0.0001 ).Conclusion Age,drinking,overweight,diabetes mellitus,increased LP (a),hyperlipoidemia,MAU and HCY are risk factors of carotid atherosclerosis and plaque formation,and the contribution of each factor can multiply and overlap,more risk factors means greater risk.

In order to solve the time-consuming problem in volume CT image reconstruction field, we brought forward a fast reconstructive algorithm method to fit the clinic medicine. First, using the great parallel and Floating-Point power of graphic processing unit (GPU), we proposed a volume CT GPU- based reconstruction method. Second, in order to reduce the repetitive operation, we separated the geometry computation and pixel computation. As a result, the computation efficiency was further improved. At last, based on the background of medical engineering, the parallel of volume CT scan and reconstruction was implemented. The results demonstrated that the volume CT reconstruction time could reduce up to 70 times compared to the previous one in common PC by the fast reconstructive algorithm method.

Objective To evaluate the role of calcineurin ( CaN)/nuclear factor of activated T cell cytoplasmic 4 protein ( NFATc4) signaling pathway in inflammatory responses in lung tissues of rats with ventilator-induced lung injury ( VILI) . Methods Twenty-four clean-grade healthy male Wistar rats, aged 5-8 weeks, weighing 220-250 g, were divided into 3 groups ( n=8 each) using a random number table method: control C (group C), VILI group and cyclosporine A plus VILI group (group CsA+VILI). The animals were anesthetized with pentobarbital and tracheostomized. The rats were mechanically ventilated for 6 h with the tidal volume set at 40 ml/kg and respiratory rate at 40 breaths/min to establish the model of VI-LI. The rats kept spontaneous breathing in group C. CaN specific inhibitor cyclosporine A 10 mg/kg was in-traperitoneally injected at 1 h before ventilation in group CsA+VILI. Rats were sacrificed immediately after ventilation, lung tissues were obtained and stained with hematoxylin and eosin to evaluate lung injury, broncho-alveolar lavage fluid was collected for determination of tumor necrosis factor-alpha ( TNF-α) , inter-leukin-1beta ( IL-1β) and IL-6 concentrations by enzyme-linked immunosorbent assay, and the lungs were removed for determination of the wet to dry weight ratio ( W/D ratio) , expression of intercellular adhesion molecule-1 ( ICAM-1) and vascular cell adhesion molecule-1 ( VCAM-1) ( by real-time polymerase chain reaction) , and expression of calcineurin and NFATc4 in lung tissues ( using Western blot ) . Results Compared with group C, the W/D ratio, lung injury scores and concentrations of IL-1β, IL-6 and TNF-αin BALF were significantly increased, and the expression of CaN, NFATc4, ICAM-1 mRNA and VCAM-1 mRNA was up-regulated in group VILI ( P＜0. 05) . Compared with group VILI, the W/D ratio, lung injury scores and concentrations of IL-1β, IL-6 and TNF-αin BALF were significantly decreased, and the expres-sion of CaN, NFATc4, ICAM-1 mRNA and VCAM-1 mRNA was down-regulated in group CsA+VILI ( P＜0. 05) . Conclusion CaN/NFATc4 signaling pathway mediates inflammatory responses in lung tissues of rats with VILI.
