Objective To evaluate the effect of wound experts′ intervention on the primary caregivers′ behavior of caring patients with pressure ulcers. Methods According to the principle of convenience sampling, 200 cases of patients with out-hospital pressure ulcers were collected in the hospital emergency department between December 2013 and December 2015. Each 100 cases were randomly divided into the intervention group and the control group according to odd even packet. Primary family caregivers in the intervention group were implemented the additional behavioral intervention by professional wound experts on the basis of the conventional education, while the control group only with conventional education. Primary caregivers′behavior score in the intervention group were compared in 1 month and 2 months. And the differences of recovery rate and incidence of pressure ulcers were compared between intervention group and control group. Results The recovery rate of pressure ulcers in intervention group was 59% (59/100) ,which was significantly higher than 32% (32/100) of the control group (χ2=14.690, P=0.000), and the incidence of pressure ulcers rate was 24% (24/100) in intervention group which was significantly lower than 39%(39/100) in the control group (χ2=5.214,P=0.022). Primary caregivers′behavior scores in the intervention group were (48.27±6.12) points after 1 month and (46.18± 4.44) points after 2 months, while those in the control group were (44.15 ± 4.33) points and (43.33 ± 5.67) points, respectively, and the difference of behavior scores in different time-points were statistically significant (F=18.93, P < 0.01). Moreover, the difference of behavior scores was also statistically significant between intervention group and control group (F=5.512, P < 0.05). Conclusions Wound experts′ intervention on home primary caregivers can effectively help improve caregivers′ behavior, promote the healing of pressure ulcers, and reduce the occurrence of complications.

Objective To investigate the effects of Qiliqiangxin capsule on serum concentration of adiponectin (APN) and heart function in patients with uremia combined with heart failure. Methods Uremia patients combined with heart failure were randomly divided into treatment group and control group , both of which were given anti-failure routine therapy. The patients in treatment group were treated with Qiliqiangxin capsule for 8 weeks and those in control group with placebo. The New York Heart Association (NYHA) heart function classi-fication, left ventricular end-diastolic diameter (LVEDD), left ventricular end-systolic diameter (LVESD), left ventricular ejection fraction(LVEF), and the levels of APN were observed before and after treatment. Results The level of APN in uremic patients combined with heart failure was significantly higher than that in normal subjects. With the increase in the class of NYHA heart function, the serum concentrations of APN increased, but the difference was not significant(P > 0.05). After 8 weeks′ treatment, the effective rate in treatment group was higher than that in control group (P < 0.05). LVEDD and LVESD in both groups decreased significantly. LVEF in both groups increased, but serum concentration of APN decreased significantly. More obvious effects were observed in treatment group (P < 0.05). Conclution Qiliqiangxin capsule could significantly reduce the level of APN and improve heart function in patients with uremia combined with heart failure.

Objective To explore the value of real‐time three‐dimensional speckle tracking imaging (RT‐3D‐STI) in the early detection of globle and regional left ventricular myocardial systolic function in patients of coronary stenosis without regional wall motion abnormality. Methods 64 coronary stenosis patients without regional wall motion abnormality were divided into 2 groups according to angiography (CAG):without coronary stenosis group( n = 20) and coronary stenosis group ( n = 44), and all the myocardial segments of the patients were divided into 5 groups:without coronary stenosis group normal myocardial segments ( n = 340 ), coronary stenosis group normal myocardial segments ( n = 235 ), mild coronary stenosis myocardial segments( n = 126), moderate coronary stenosis myocardial segments( n =213) and severe coronary stenosis myocardial segments( n =174). Real‐time three‐dimensional full volume of left ventricle was obtained, left ventricular global area strain (GAS)and regional area strain(AS) of 17 myocardial segments, etc, were measured by RT‐3D‐STI respectively. The parameters between the two groups and among the five sub groups were compared, the correlation between GAS and coronary artery Gensini score was also analyzed. Results GAS in coronary stenosis group significantly reduced compared with without coronary stenosis group( P <0 0.5) S.egmental AS gradually reduced with the increasing of the degree of the coronary stenosis. There was no statistically difference of segmental AS among without coronary artery group normal myocardial segments, coronary stenosis group normal myocardial segments and mild coronary stenosis myocardial segments( P >0 0.5) S.egmental AS in moderate and severe coronary stenosis myocardial segments significantly reduced ( P < 0.05 ), and that in severe coronary stenosis myocardial segments was lower than that in moderate coronary stenosis myocardial segments, the differences were statistically significant ( P < 0.05 ). In addition, GAS was significantly correlated with coronary artery Gensini score( r =0.828, P <0.01). Conclusions RT‐3D‐STI can quantitatively assess the early changes of left ventricular globle and regional myocardial systolic function in patients with coronary stenosis.

BACKGROUND:To optimize the oral implant design in the abutment angle has an important effect on bone resorption, and meanwhile, the high bite force from patients is also crucial to rebuild bone absorption.
OBJECTIVE:To optimize the model design of the maxilary anterior teeth using Ansys Workbench 13.0 software and to investigate the stress size on the cortical and cancelous bone from different angled abutments and different loads of the central incisor.
METHODS:A three-dimensional finite element model of the V-shaped cylindrical threaded implants in the maxilary bone. Abutment angle was set as 0°, 5°, 10°, 15°, 20°, 25°, 30°, and the load stress was set as 90, 105, 120, 135, 150, 165, 180, 195, 210 N. Occlusion of the central incisor was simulated on the implants, and then, buccolingual mechanical loads were loaded on the center of prostheses to observe the effects of different abutment angles and loads on the Von Mises peak stress of the maxila and mandible.
RESULTS AND CONCLUSION:Under the influence of a single factor, when the abutment angles acted as variables, the Von Mises peak stress of the cortical and cancelous bone was respectively increased by 60.60% and 69.30% under labial or palatal loads; when the loading stress acted as variables, the Von Mises peak stress of the cortical and cancelous bone was increased by 68.74% and 69.30% under buccolingual loads. When the loading stress was less than 150 N and the abutment angle was less than 25°, the slop of tangent for the mandible Von Mises stress response curve was-1 to 0. It seems from the mechanical analysis that the stress of cancelous bone is more susceptible to abutment angle and load stress; the optimal abutment of screwed implant should be designed to an angle less than 25° and an bite force less than 150 N.
