Objective To investigate the clinical effects of surgical small incision treatment of patent ductus arteriosus (PDA) in premature infants with titanium clip.Methods One hundred children received and cured by our hospital from January 2010 to January 2013 were divided into two groups.Group A:body weight ＞ 1.5 kg of patent ductus arteriosus (PDA),71 cases of premature children; group B:body weight ＜ 1.5 kg of low body weight preterm the children PDA,29 cases.The operations were performed in the newborn intensive care unit (NICU).The patient was placed in a lateral position with the left arm abduction under general anesthesia.A 1.5-2.5 cm long posterolateral mini-thoracotomy was made and the pleural cavity was entered via the 2-3rd intercostal space.The PDA was closed with two titanium clips.Results Ninety-nine cases were cured,1 died.2 residual shunt postoperatively.One patient on postoperative 5 day was found wound infected,wound healing after the use of antibiotics by intravenous.There was no significant difference in incidence of postoperative complications and mortality rate between group A and group B (P ＞ 0.05).Majority of children successfully weaned from the ventilator due to the rapid improvement of hemodynamics and lung conditions.In group B,mechanical ventilation time (12.6 ± 7.5) d and postoperative hospital stay (21.0 ± 15.4) d was significantly longer than group A ((9.6 ± 4.2) d and (12.0 ± 10.8) d),the difference between the two groups was significant (t =7.35,9.12,P ＜ 0.05).Conclusion (1) It is a viable treatment that bedside minimally invasive titanium clip closed ductus arteriosus in preterm children PDA.(2) As the treatment of low body weight premature children is poor,the tolerance of the surgical trauma of the surgery as a minimally invasive,simple method is particularly suitable for low body weight premature children PDA.

Objective To sum the clinical experiences of the treatment in congenital heart disease single ventricle with extracardiac conduit (EC) fenestration.Methods Ninety-five patients diagnosed with univentricular heart disease underwent EC using Gore-Tax conduits at the Department of Children's Heart Center,Justus-Liebig-University Giessen Germany from June 1996 to July 2010.According to EC with or without fenestration,the patients were divided into two groups.Seventy-one routine fenestration of the extracardiac conduit (the fenestration group),58 patients (58/71) of children with high-risk preoperative intraoperative fenestration,13 cases (13/71) were due to low cardiac Rankinginterventional fenestration; extracardiac conduit fenestration (non-windowed group) did not undergo surgery in 24 patients (24/95).Results The fenestration had no death; Three died in non-windowed group.Postoperative effusions and postoperative mean pulmonary artery pressure in group without fenestration ((14.2 ± 2.3) d and (15.1 ± 3.4) mm Hg respectively) were significantly higher than group with fenestration ((10 ± 3.2) d and (13.2 ± 2.8) mm Hg respectively).It had significant differences(P =0.016).In the group with fenestration and without fenestration,postoperative oxygen saturation((90.3 ±4.0)％,(91.7 ±5.2)％),postoperative thrombosis (11.3％ (8/71),12.5％ (3/24)),and postoperative neurological problems (18.3％ (13/71),20.8％ (5/24)) did not differ between cohorts.Conclusion It is effective and safe to treat congenital heart disease single ventricle with EC.EC with fenestration can improve acute postoperative mortality by rising cardiac output,thereby can reduce early postoperative mortality.

Objective To explore the effects of environmental factors such as temperature, relative humidity and ventilation rate on release quantity of formaldehyde in woodiness boards. Methods A small climate chamber was employed to control the temperature, concentration of vapor and ventilation rate. The quantity of formaldehyde released from woodiness boards was determined by 4160 Formaldehyde Analyzer of INTERSCAN. Results The released quantity of formaldehyde increased from 0.12 mg/(m2?h) to 0.35 mg/(m2?h) as the temperature increased from 18 ℃ to 38 ℃, it increased from 0.20 mg/(m2?h) to 0.46 mg/(m2?h) as the concentration of vapor increased from 3.99 mg/L to 15.75 mg/L, it increased from 0.21 mg/(m2?h) to 0.62 mg/(m2?h) as the ventilation rate increased from 0.5 h-1 to 2.0 h-1. Conclusion The emission rate of formaldehyde in woodiness boards will be accelarated when the temperature, concentration of vapor and ventilation rate increased.

The distance between the medial border of the two articular processes was measured by CT and MRI. At the level of C5-6-7 it was 23-25 mm(24mm on average). If the distance is 24 mm at C5-6 a tuohy needle is inserted 10 mm(24?2-2) lateral to the midline. When the needle touches vertebral lamina, withdraw the needle 2mm and redirect it cephalad at 45-60, Resistance is encountered when the needle touches ligament flavum. When the resistance disappears, the tip of the needle has entered the lateral recess via tuohy needle. This approach was used in 45 patients with satisfactory results. In ten patients the position of the cathter was confirmed with contrast medium by CT and MRI.

Objective To evaluate the effect of Danshen Chuanxiongqin injection combined with Xuesaitong capsule on blood viscosity in patients with pulmonary heart disease.Methods 80 patients with pulmonary heart disease who were admitted to our hospital between January 2013 and November 2015 were studied,the patients were randomly divided into the combined group and the control group according to the order of admission,40 cases in each group.Control groups were treated with Xuesaitong capsule,and the combined group were treated with Danshen Chuanxiongqin injection on the basis of the control group.The clinical efficacy,blood viscosity(whole blood viscosity,plasma viscosity,whole blood viscosity ratio),blood indexes(blood platelet aggregation rate,erythrocyte aggregation index,erythrocyte deformation index),cardiac function and safety were observed.Results There were no significant differences in blood rheological indexes,LVEF,MAP and HR between the two groups before treatment.After treatment,the whole blood viscosity,plasma viscosity,whole blood viscosity ratio,platelet aggregation rate,erythrocyte aggregation index,erythrocyte deformation index,MAP and HR in the two groups were significantly lower than those before treatment,while LVEF was significantly higher,and the changes in the combined group were more significant than those in the control group(P<0.05).After treatment,the clinical total effective rate of treatment in the combined group(88.89％)was significantly higher than that in the control group(62.50％).Conclusion Danshen Chuanxiongqin injection combined with Xuesaitong capsule is effective in the treatment of pulmonary heart disease.It can significantly reduce blood viscosity,blood related indexes and improve cardiac function.
