Objective To observe the changes of systolic time interval after neonatal asphyxia and explore its relationship with clinical manifestation and prognosis. Methods Tow-dimensional and Doppler echocardiography were employed to detect tow - dimension parameters and left and right ventricular STI in 27 mild and 18 severe asphyxiated neonates as well as 14 normal controls and its relationship with clinical manifestation and prognosis was analyzed. Results There was no difference in cavity and thickness of heart and great arteries between normal and asphyxiated neonates. In acute stage mild and severe asphyxiated neonates had a shorter right ventricular ejection time (RVET) than normal neonates and a longer right ventricular prejection period (RPEP) was found in severe neonates than that in normal and mild asphyxiated neonates. Left ventricular preejection time (LPEP) was prolonged in comparison with normal neonates in acute stage and convalescence. There were more cases with increased RPEP/RVET in severe asphyxiaed group than those in mild and normal group in acute stage. The incidence of heart failure in acute stage and disability in late period was higher in cases with increased RPEP/RVET than that with normal RPEP/RVET. Conclusion Asphyxia has more severe damage to right ventricle than that to left ventricle. Cases with increased RPEP/RVET are prone to suffering from heart failure in acute stage and more likely to undergo disability in late period.

Objective: This study was undertaken to explore the effect of left ventricular assist device (LVAD) on failing heart after myocardial ischemia. By detecting the changes of plasma atrial natriuretic peptide (ANP), brain natriuretic peptide (BNP) and cardiac troponin I (cTnI) levels within 6 hours after the implantation of LVAD, we review the basis on which neurohormones may be used to determine prognoses of failing heart and choose an optimal predictor. Methods: 15 adult healthy dogs were divided into 3 groups randomly. The LVAD was implanted in LA-AO bypass in all three groups. Myocardial ischemia was induced by ligating the main left anterior descending coronary artery (LAD). In group A, after a ligation of 10 minutes, the myocardium was reperfused for 6 hours. In group B, after a ligation of 40 minutes, the myocardium was reperfused for 6 hours. In group C, after a ligation of 40 minutes, the LVAD was used for LV support for 6 hours. Results: After 6 hours reperfusion,in group C, the hemodynamics was significantly improved, the ANP, BNP and cTnI were return to normal level, and myocardial ultrastructure was recovered significantly. While in group B, the hemodynamic, the neurohormones, and myocardial ultrastructure were worse. Relational analysis demonstrated that ANP and cTnI levels were influenced by hemodynamics obviously, but there was a weak relationship between circulating BNP and hemodynamics. Plasma BNP level was able to identify the cardiac function status. Conclusion: LVAD can be beneficial to improve cardiac function and can reduce the plasma levels of ANP, BNP and cTnI. Plasma BNP level can identify the cardiac function status. Those findings indicated that plasma BNP determination provides important prognostic information about cardiac function and may be a better prognostic indicator.

Even though closed treatment of Colles' fracture leads to satisfactory clinical results, many patients who have had such a fracture are found to have permanent disability and poor function of hand and wrist. Malunion occurs frequently following Colles' fracture and there is considerable disability, pain and deformity associated with this lesion. Such deformity of wrist can usually be prevented by proper treatment, but if deformity developes, better function and a normal appearing wrist can be restored by a corrective osteotomy. The authors experienced 6 cases of malunited Colles' fracture which had been treated by corrective osteotomy, Darrach resection, and osteoclasis, etc.

OBJECTIVETo explore incidence rate, influencing factors, leakage routes,and preventative measures of bone cement leakages in vertebral internal reinforcement operation including percutaneous vertebroplasty and percutaneous kyphoplasty.

METHODSFrom January 2010 to January 2012,94 patients with osteoporotic vertebral compressive fracture,vertebral metastases and vertebral hemangioma were treated by vertebral internal reinforcement operation. Among them, there were 39 males and 55 females aged 55 to 86 with an average of 69.4 years old. The reasons, types, incidence and complications of bone cement leakage were analyzed.

RESULTSTotally 21 patients (26 vertebral) occurred bone cement leakage, the main routes included basivertebral veins, and bone cortex, which mainly located on adjacent intervertebrae and around vertebral body, and most of them were asymptomatic leakage. For the treatment of OVCFs, incidence of bone cement leakage in PKP was lower than that of PVP (P < 0.05), while incidince of PVP in treating vertebral metastases was worse than in treating OVCFs (P < 0.05).

CONCLUSIONBone cement leakage is a common complication in PVP and PKP. Careful analysis before operation, cautiously monitors and grasp operation indication in operation can decrease incidence of it.

Objective To summarize the clinical features,diagnostic and treatment experience of severe hand,foot and mouth disease(HFMD) cases receiving mechanical ventilation from Jan 1 to Sep 6,2009 in our hospital and provide reference for reducing the occurrence of neurogenic pulmonary edema(NPE) and mortality. Methods 147 severe HFMD who received mechanical ventilation were analyzed by a retrospective investigation. Results 85.0% children were less than 3 years old and 100% patients had a fever. The mechanical ventilation occurred within 1 to 4 days after fever (3.06 ± 1. 02) d. Neurological complications presented as bad spirit,easy surprised, involuntary movement of the extremities and lethargy. Respiratory system complication presented as polypnea, hypepnea and irregular rhythm. Circulatory system complication presented as heart rate increase or decrease, hypertension or hypotension, piebald skin and low limb temperature.Some of the children had high white blood cell counting,glucose and lactic acid of the blood. The EV71-PCR positive rate was 34. 7% for throat swabs,and 42. 2% for anal swabs. Chest X-ray presented as increased broncho vascular shadows, exudation or nonapparent abnormality. Only three children were dead, fatality rate was 2. 0%. Conclusion The HFMD cases in this outbreak are relatively more serious,and change rapidly. It's difficult to treat as soon as NPE appeared,and it has high fatality rate. Early recognition of critical patients,timely giving mechanical ventilation,and the comprehensive treatment can reduce NPE incidence and the mortality.

Objective To study the impact of the peripheral neurotomy method combined with rehabilitation exercise on gross motor function and balance function of children with cerebral palsy.Methods Matched pair design was used in the study.Thirty children with spastic cerebral palsy hospitalized from May 2011 to Nov.2013 suffering from peripheral neurotomy were assigned as study group,who were conscious and treated by peripheral neurotomy com bined with rehabilitation exercise.In the meanwhile,30 children inpatients at the same time were employed as the control group,who were similar in age and symptoms,with the same gender and the same Gross motor function classification (GMFCS) grade,and the controls were treated only with ordinary rehabilitation exercise.Modified Ashworth score,Gross Motor Function Measure (GMFM) D and E regions scores,physicians rating scale score in the 2 groups were recorded after treatment for 2,4,6,8,10 weeks.Repeated measure analysis of variance method was introduced to analyze the differences between the 2 groups in improved Ashworth muscle tension,gait improvement,gross motor function and balance function.Results The study group was superior over the control group in muscle tension reduction (F =8.177,P =0.006) and gait improvement(F =24.284,P =0.000).The 2 groups were not different statistically in D region evaluation of GMEM (F =0.072,P =0.790) and E region evaluation of GMFM (F =0.000,P =0.985) ; For Berg balance scale,the 2 groups had also no difference(F =0.150,P =0.700).Conclusions Both peripheral neurotomy method combined with rehabilitation exercise and the ordinary rehabilitation exercise method both could improve the gross function and the balance function.Furthermore,the former was superior over the latter in muscle tension reduction and gait improvement.
