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 observe the neuroprotective effect of celecoxib against degeneration of dopaminergic neurons caused by lipopolysaccharide in vivo.Methods The rat model of Parkinson disease(PD)was established by intranigral injection of lipopolysaccharide.Sprague-Dawley rats were randomly divided into control group,PD group,and celecoxib group.Behavioural changes were recorded,and the expressions of tyrosine hydroxylase(TH)and cyclooxygenase-2(COX-2)were determined by immunohistochmistry and Western blot.Results No behavioral change was found in control group.There was significant difference in the number of circling behavior between PD and celecoxib groups(196.90±9.52 vs 109.30±9.38,P＜0.01).The number of TH-positive cells and the expression of TH protein in rat substantia nigra were significantly higher in celecoxib group than in PD group(P＜0.01).Compared with PD group,the number of COX-2positive cells and the expression of COX-2 protein were significant lower in celecoxib group(P＜0.01).Conclusion Celecoxib has neuroprotective effect on the degeneration of dopaminergic neurons caused by lipopolysaccharide in vivo.

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.

Objective Currently, the effect of hydrogen peroxide solution( H2 O2 ) flush on the recovery of peripheral nerve injury are still undetermined. This study aims to explore the effects of different H2 O2 flushing time course on recovery of peripheral nerve injury during surgical debridement. Methods 18 New Zealand male white rabbits were randomly divided into isotonic saline group( isotonic saline flush) , H2 O21 min group ( hydrogen peroxide solution flush 1 min + isotonic saline flush) , H2 O23 min group ( H2 O2 flush 3 min + isotonic saline flush. Each group has 6 rabbits. We established rabbit sciatic nerve injury model. After 12 weeks, we executed the animals, drew materials at the suture nerve, detected motor nerve conduction velocity and observed pathological HE staining, as well as measuring the sciatic nerve function indexes( SFI) of rabbits at the 8th and 12th week, respectively. Results Nerve conduction velocity in H2O21min group and isotonic saline group[(25.89±1.42), (26.46±1.67) m/s] were higher than that in the H2O23min group[(23.80±2.91)m/s](P<0.05). Pathological section shows that the isotonic saline group has a better sheathstructure, nerve fibers structure damage is not obvious and myelin degeneration degree is mild in H2 O21 min group. blurred sheath structure and myelin axons obvious deformation in H2 O23 min group. 8 weeks and 12 weeks after operation, SFI in isotonic saline group [(-43.00±0.82), (-39.17±0.91) m/s] was significant higher than H2O21 min group [ (-49.79±1.47), (-46.60±0.79) m/s] and H2O23min group [(-51.66±1.27), (-46.39±0.94) m/s], thedifference was statistically significant (P<0.05). SFI in group of H2O21min [(-49.79±1.47)m/s] was higher than group og H2O23 min [(-51.66±1.27) m/s][P<0.05]. Conclusion H2O2 solution has side effect on the recovery of damaged peripheral nerve inju-ry and with prolonging the H2 O2 flushing time, the damage of peripheral nerve can be aggravated. So in the process of clinical surgical debridement, under the premise of guaranteed sterilization the time of H2 O2 flush should be shortened as far as possible.
