Objective To observe the efficacy,feasibility and safety of continous intravenous infusion of furosemide,dopamine combined with Shenmai on treatment of refractory heart failure. Methods Fifty-six patients with diuretic resistance and refractory heart failure were divided into control group(28 patients)and treatment group(28 patients)by random digits table. Conventional diuretics and other anti-heart failure treatment were used in two groups, meanwhile, continuous intravenous infusion of furosemide,dopamine and Shenmai were used in treatment group for 5-7 days. The clinical symptoms and signs, pulmonary edema in chest X-ray and the improvements of pulmonary congestion were observed before and after treatment. Results In treatment group, 10 patients were markedly effective, 14 patients were effective, and 4 patients were unfruitful. The total effective rate was 85.7%(24/28). In control group, 3 patients were markedly effective, 10 patients were effective, and 15 patients were unfruitful. The total effective rate was 46.4%(13/28). There was significant difference in total effective rate between two groups (P < 0.05). The indexes of left ventricular end-diastolic dimension, fractional shortening, left ventricular ejection fraction and cardiac index were significantly improved in treatment group(P < 0.05), but was not significantly improved in control group(P > 0.05). After treatment,2 patients emerged hypokalemia and hyponatremia, after symptomatic treatment,they all recovered. Conclusion Conventional treatment combined with continuous intravenous infusion of furosemide,dopamine and Shenmai in patients with refractory heart failure is markedly effective, feasible and safe.

7.Three-dimensional finite element analysis of Kirschner nails and external fixation for Bennett fracture
Chinese Journal of Tissue Engineering Research 2017;21(3):390-395
BACKGROUND:Klinefelter nails and external fixation were commonly used treatment methods for Bennett fracture, but study about biomechanics of two methods was little. OBJECTIVE:To establish three-dimensional finite element models of Bennett fracture by Klinefelter nails and external fixation, and analyze its biomechanics. METHODS:Three-dimensional models of Bennett fracture were established by smal external fixation and Kirschner nail treatment. The Bennett fracture models established by smal external fixation treatment were considered as model A. Bennett fracture models established by Kirschner nail treatment were considered as model B. 120 N load was applied to the first metacarpal X-axis direction. The X-direction displacement and total displacement of model A and model B, and the fracture fragments stress of model A and model B were observed. RESULTS AND CONCLUSION:(1) In the X direction, the absolute values of maximum displacement and minimum displacement of model A at proximal fragment and distal fragment were less than model B;the maximum relative displacement, minimum relative displacement and average relative displacement of model A were less than model B. The differences of the average displacement of the proximal fracture fragment and the distal fragment, and the relative mean displacement in two models were statistical y significant (P<0.05). (2) In total displacement, absolute values of the maximum displacement and minimum displacement of model A at proximal fragment were less than model B;absolute values of the maximum displacement and minimum displacement of model A at distal fragment were less than model B;the maximum relative displacement, minimum relative displacement and average relative displacement of model A were less than model B. The differences of the average displacement of the proximal fracture fragment and the distal fragment, and the relative mean displacement in two models were statistical y significant (P<0.05). (3) The maximum stress value, a minimum stress value and the average stress values of fracture fragments of model A were significantly smal er than model B. The difference of the mean stress value in two models was statistical y significant (P<0.05). (4) These findings showed that the X-direction displacement and the total displacement were smal er, and the fracture fragments stress was uniform in smal external fixation and Kirschner nail treatment for Bennett fracture, indicating that smal external fixation for Bennett fracture has more advantages compared with Klinefelter nail.

Chinese Journal of Practical Nursing 2016;32(22):1724-1726
Objective To investigate the postoperative self-care ability and its influence factors in patients with esophageal cancer. Methods The self-made basic status questionnaire, exercise of self-care agency scale and social support rating scale were used to survey 106 cases with esophageal cancer from Jan. 2012 to Dec. 2014. The risk factors of self-care ability were analyzed. Results 101 effective questionnaire were got and the effective rate was 95.28%. The total score of self-care ability was (108.6± 21.5), 45 cases (44.55%) were at higher level and 56 cases (55.45%) were at moderate level. Univariate analysis showed educational level, chronic health disorders and health perception were associated with the total score of postoperative self-care ability (All P<0.01). The total score of social support were (43.5±6.5) and positively correlated with self-care ability (r=0.325,P<0.01). The multiple linear regression analysis revealed that education level, health perception and social support were important risk factors of self-care ability (t=2.926,-3.654, 2.301, All P<0.05 or 0.01). Conclusions The level of postoperative self-care ability in patients with esophageal cancer is not high. For the patients with low level of education, health perception and social support, nurse should enhance the health education.

10.ENZYME HISTOCHEMICAL STUDY OF EXPERIMENTAL RABBIT INCISED WOUND
Chinese Journal of Forensic Medicine 1986;0(01):-
Enzyme-histochemical investigations on experimental incised injury of thirty rabbits fortiming of wound were reported.In peripheral areas of wounds,strong reaction of six kinds ofdehydratase(ACP.AKP,ATP.ANAE.?—GA,?—Gr).were demonstrated 1~2 hrs followingincision while no reaction of four kinds of dehydrogenase(LDH.SDH.NADH.?—GPDH)werefound.The activity of dehydratase are explained by the enhanced metabolism of fibrocytes and theaggregation of acute inflammatory cells.The author suggests that the positive enzyme histochemicalreactions indicate the vital reaction in the first two hours,and PTAH staining is helpful for thediagnosis of micro—exudation of fibrin in the early stage of injury
