30ml) undergoing minimally invasive evacuation of intracranial hematoma in our department were analyzed retrospectively.The chants of IL-1,IL-6 and IL-8 in hematoma fluid were observed continuously.The content of IL-1,IL-6 and IL-8 was determined by radioimmunassay.Results IL-1,IL-6 and IL-8 were observed at 6～12h after hypertensive cerebral hemorrhage,and showed different changes in acute stage.Conclusion Inflammatory cytokines are involved in the pathological process of cerebral hemorrhage.

Objective To explore the common clinical features and mechanism of HenochSchonlein purpura (HSP) in children,and provide evidence and guidance for clinical diagnosis,therapy and prognosis of HSP.Methods Prospective study.Totally 1 232 HSP children blood samples were collected during January 2010 to December 2013 in the Children's Hospital of Zhejiang University School of Medicine,and the levels of immunoglobulin,complement,T lymphocyte subsets and CRP were detected in the acute phase of HSP.The clinical data were analyzed with these indexes to explore the function of cellular and/or humoral immunity in the pathogenesis of HSP.In addition,this study detected serum IgA levels in 200 cases of sepsis rash,200 cases of urticarial and 200 cases of thrombocytopenic purpura patients and 400 cases of healthy children over the same period to our hospital respectively,in order to find out whether IgA is capable of differentiating allergic purpura rash from other similar skin rashes.Results Compared with healthy children,the IgA level was significantly higher [IgA:2.0 (0.6-7.5) g/L vs 1.1(0.6-2.1) g/L,Z =5.928,P =0.03].When IgA ＞ 1.44 g/L,the diagnostic sensitivity and specificity to differentiate allergic purpura patients from sepsis patients were 77.43 ％ (954/1 232) and 80.00％ (160/200),respectively.When IgA ＞ 1.53 g/L,the diagnostic sensitivity and specificity to distinguish from allergic purpura with urticaria patients were 72.57％ (894/1 232) and 74.51％ (149/200).When IgA ＞0.91 g/L,it had a 95.14％ sensitivity (1 172/1 232) and a 79.45％ specificity (159/200) for the differential diagnosis of allergic purpura and thrombocytopenic purpura patients.When IgA ＞ 1.33 g/L,the sensitivity of distinguishing allergic purpura patients from healthy children was 81.25％ (1 001/1 232),while the specificity was 95.00％ (380/400).Conclusions HSP children show cellular immune dysfunction.Th1/Th2 imbalance and over-activation of Th2 cells result in the increased synthesis and release of immune globulin,causing abnormalities in humoral immune.An increase in serum IgA level of HSP patients can differentiate HSP from other similar rashes.

Objective To evaluate the human left ventricular flow field structure by vector flow mapping (VFM),and to seek the formation rules and description parameters of swirl vortex in the human left ventricular.Methods Sixty heathy adults were involved.The velocity distribution images on the section plane of the flow in the left ventricular were obtained bv VFM,and series parameters of vortex including vortex diameter(transverse and vertical diameter),vortex position(transverse and longitudinal position),vortex maximum flow velocity (Vmax)and density number of vortex ring(N)were measured with the software named DSA-RS1.Results A pair of similar vortex showed by VFM in the left ventricle of the heart during the early and late diastole period which were formed by a strong jet flow through the mitral valve were small vortex,and Vmax and N in former were bigger than that in latter(P＜0.05),while a bigger vortex ring continued during the middle diastolic and isovolumic contraction period with a trailing jet in the left ventricle were large whirlpool,and Vmax and N in former were bigger than that in latter(P＜0.05).Conclusions Changes of the intraventricular blood flow field structure can be showed by VFM,and description parameters of vortex concluded from the study can reflect the changes,which can be used as a preliminary quantitative study of the complex flow field structure in heart chamber.

Objective To discuss the worthiness of real-time three-dimensional echocardiography in researching normal fetal heart ventricle growth and systolic function. Methods End-systolic volume(EDV),end-diastolic volume(ESV), struggle volume(SV) and ejection fraction(EF) of 54 normal fetal were acquired from 3-D data by Qlab software. The relation between ventricular growth with pregnant week was analysed and the difference of the volume and systolic function between left ventricle with right ventricle were compared. Results Ventricular volume of normal fetal heart (EDV,ESV,SV) were all increased with the gestational ages,there was linear relativity between them,while EF was not increased with pregnant weeks,there was no linear relativity between them. There was no statistics difference on EDV and ESV between left ventricle and right ventricle, while there was statistics difference on SV, EF between them. Conclusions The image of fetal endocarium could be derived clearly by real-time three-dimensional echocardiography, which help to get fetal heart ventricular volume and to study fetal heart growth and function.

Objective To compare the formation and evolution of left ventricular flow between the patients with the bileaflet artificial mechanical mitral valve and normal adult using vector flow mapping (VFM). Methods Thirty healthy controls and 30 severe mitral stenosis patients with bileaflet prosthesis mitral valve were involved. The left ventricular flow and the vortex description parameters were comparatively studied between two groups. Results Two small symmetric rotating vortexes and a big counter-clockwise rotating vortex appeared alternately in the left ventricular through cardiac cycle with control group. In case group,only large vortex could be seen in the mid-late diastolic and maximum vector velocity was faster than that in control group in statistics( P <0. 05). Especially the postoperative direction of blood flow was clockwise shif ting from the interventricular septum to the posterior and lateral left ventricular wall inversely to control group. Conclusions VFM can show the complex vortex flow patterns in left ventricular in the patients with bileaflet prosthesis mitral valve preliminarily and may be useful to assess and improve the function of prosthesis valve in future.

Objective To study on the effect of nttrsing intervention on coping with fatigue in patients with cervical spine fracture and high paraplegia.Methods 46 patients who suffered cervical spine fracture with paraplegia were divided into the control group and the intervention group with 23 patients in each group randomly.The control group received routine care in general,while the intervention group was given additional systematic nursing intervention by full-time nurses.The brief fatigue inventory(FSI),as fatigue assessment tools,was used to assess the fatigue of patients in the two groups before invention and 20 days after invention respectively.Results As a result,we found that the difference of fatigue between the two groups had no prominent significance before intervention,but after invention the difference had prominent significance.Conclusions The nursing intervention is very important for patients with cervical spine fracture and paraplegia and has significant advantages to alleviate or eliminate patients' fatigue and improve their quality of life.

Objective To explore the security and its influencing factors on benign airway stenosis treated with interventional of high pressure balloon expansion catheter.Methods Clinial data of 39 cases of inpatients suffered from benign airway stenosis were chosen.17 cases were male,and 22 cases were female.The ages of them ranged from 15 to 83 years old.According to the clinical symptoms,HRCT 3D reconstruction,and the results of bron-choscope,all patients were treated with balloon expansion catheter at different criterions.The balloon catheter with size that slightly smaller than the targeted normal bronchial tube was chosen,expansion for average 1 -4 times,single balloon expansion time ranged from 0.5 to 4 min,the pressures were kept at 3 -6 atmosphere,and the highest pres-sure did not exceed 8 atmospheric pressure.The efficacy and complications were retrospectively analyzed.Results 19 cases were completely effective,14 cases were basically effective,6 cases were completely ineffective,and the total effective rate was 84.6% (33 /39 ),the incidence of complications was 35.8% (14 /39 ),moreover,no deaths occurred.Conclusion High pressure balloon catheter expansion is one of commonly used technology in breathing interventional treatment;it has the characteristics of easy operation,and immediate curative effect,and so on.But if the improper operation,incorrect selection of the case,or inaccurate evaluation of the stenosis during operation,serious complications and unnecessary iatrogenic injury can be occurred.Therefore,it is worthy of attention and further summarizing by breathing interventional physicians.
