Objective To explore the diagnosis,treatment and pathology of malignant brain tumor in children.Methods The clinical data of 61 children with malignant brain tumor were reviewed,including their age distribution,diagnosis,operation route(according to the position of the brain tumors),chemotherapy [using bischloro-nitrosourea(BCNU),teniposide(VM-26) and temozolomide]and radiotherapy (part and whole brain irradiation,three diamensions conformal therapy,gamma knife and X-kinfe).Results Of 61 cases,which including 37 boys and 24 girls whose mean age was 11.3 years,24 cases were supratentorial tumors and 37 cases were infratentorial.Forty-five tumors received total or subtotal recession,10 cases with major recession,and 6 cases with partial recession.After operation,39 cases (63.9%) received radiotherapy,and 29 cases (47.5%) with chemotherapy.Follow-up of 49 cases were achieved,in which 22 cases died and 27 cases survived.Conclusions Surgical removal is still the chief treatment for malignant brain tumor in children.The exairesis profect should be formulated according to the specificity of each case.Radiotherapy methods should be related to post-operational images(CT or MRI).And it was different from the brain tumors in adult.It is good to prolong survival duration for some chosen cases with optimal chemotherapy.

Objective To evaluate the clinical value of real-time 3 dimensional echocardiography (RT-3DE) for measurement of right ventricular function in the repaired tetralogy of Fallot (TOF) compared to cine magnetic resonance imaging (c-MRI).Methods Thirty-seven randomly selected patients with repaired TOF from Jan.2000 to Jun.2007 in Children's Hospital,Fudan University underwent both RT-3DE and c-MRI for the data of right ventricular enddiastolic volume (RVEDV),right ventricular end-systolic volume (RVESV),right ventricular ejection fraction (RVEF),which were compared to evaluate the reproducibility and correlation of two ways on right ventricular function.Results All the patients completed both RT-3DE and c-MRI on the same day.The correlation for RVEDV,RVESV,RVEF measured by 2 methods was high (r =0.933,0.943,0.911,P =0.000,0.000,0.105),and it showed that consistency existed in RVEF,as difference was only (1.2 ± 4.5) ％.Comparison with c-MRI,RVEDV and RVESV measured by RT-3DE was underestimated,in which difference was (-17.4 ± 16.9) mL,(-9.3 ± 10.5) mL.Conclusions RVEF with RT-3DE can be assessed with acceptable accuracy,but it is not so good for RVEDV and RVESV.Further study needs to be performed to make sure the value of RT-3DE on the assessment of right ventricular function in repaired TOF.

Objective To study the feasibility of using gooseneck snare combined with 0.035 inch loach guidewire for subintimal angioplasty in iliac artery occlusion , and to discuss its clinical indications. Methods During the period from October 2011 to May 2013, 3 cases with unilateral complete iliac artery occlusion were admitted to authors’ hospital. As the guidewire inserted from the healthy side could not returned into the true lumen once it entered into the subintimal space of the iliac artery , the puncture at the diseased side was carried out and the guidewire was pushed into the artery , but the catheter and the guidewire could not converge or anastomose in the subintimal site , gooseneck snare had to be used to grab the guidewire in subintimal site as to establish a path and completed the angioplasty. Results Successful and safe balloon dilatation and stent implantation were accomplished in all the 3 patients , and the patients complained of no special discomfort. Conclusion In performing the subintimal angioplasty for patients with iliac artery occlusion, the use of gooseneck snare combined with retrograde insertion of guidewire should be considered when it occurs that the guidewire can not return into the true lumen after it enters into the subintimal space. Nevertheless, gentle manipulation is first important in order to avoid the possible rupture of vessels.

Objective To observe the effects of early intravenous administration of Astragalus on brain inju-ry in neonates with severe asphyxia. Methods According to hospital serial number, 80 neonates with severe as-phyxia were divided into conventional treatment group (control group) (n=40), which was on the basis of symp-tomatic support treatment for the use of cerebrolysin and citicoline treatment; Astragalus injection treatment group (n=40), which, apart from the conventional treatment, Astragalus injection was given as soon as possible (within six hours after birth). The incidence of convulsions or frequent seizures convulsions and the mortality in two groups, the clinical degree of hypoxic ischemic encephalopathy (HIE) and the behavior nerve score determination were ob-served and compared. Results The incidence of convulsions or frequent seizures convulsions was significantly lower in the Astragalus treatment group than in the control group (45.00% vs 67.50%, χ24.501,P<0.05). The per-centage of the behavior nerve score determination in 7 d-8d and 12 d-14d after birth was obviously lower in the for-mer group than the latter one (48.57% vs 74.19%, χ2 4.642,P<0.05; 31.42% vs 58.06%, χ24.601, P<0.05). The mortality was not significant different between the two groups (12.50 % vs 22.50%, χ22.000, P>0.05). Conclusion For severe asphyxia neonates, on the basis of the symptomatic support treatment, the use of Astragalus injection, as soon as possible, can significantly reduce the hypoxic ischemic brain injury.
