Objective To analyze the clinical features of organic damages in Kawasaki disease(KD),and to improve the diagnosis and treatment level.Methods Two hundred and two cases with KD admitted in Children's Hospital Affiliated to Capital Institute of Pediatrics from Jan.2000 to Oct.2007 were reviewed,and their blood routine,urine,stool routine,liver function,kidney function,chest X-ray,and so on,were investigated.The incidence of organic damages in KD was evaluated.Results Among the 202 KD children,137 were male and 65 were female,the male-female ratio was 2.11.0.Most of them were infants,and 71.3% of them were younger than 3 years old.The damages of hematological system were detected in 78/202 cases(38.6%),respiratory system 76/202 cases(37.6%),cardiovascalar system 68/202 cases(33.7%),urinary system 52/202 cases(25.6%),digestive system 23/202 cases(11.4%),and central nervous system 3/202 cases(1.5%).On the other hand,3 cases complicated with septemia,1 case with juvenile rheumatoid arthritis and 1 case with Henoch-Schonlein purpura.Conclusions The data indicate that the incidence of hematological system involvement in the sick-children with KD were highest,with more than 2 organs involved simaltaneously.Many organic damages were involved in KD and diverse clinical manifestation could be found.Physicians should understand not only the typical features but also the rare symptoms and organic damage so as to prevent misdiagnosis and improper treatment.J Appl Clin Pediatr,2009,24(1):31-32

Background Researches have suggested that the defocus can induce the change of static visual acuity,but whether it produce influence on dynamic visual acuity is not clear.Objective This study was to investigate the impact of myopic defocus on static visual acuity and dynamic visual acuity and explore the essential difierence between static visual acuity and dynamic visual acuity. Methods Forty volunteers were enrolled in this trial.including 20 adults with the age of 27.4±1.64 years and 20 children with the age of 11.70+1.49 years.All the eyes of subjects received regular examined to excluded the eye disease with the best corrected vision of ≥1.0 D,astigmatism of ≤0.75 D and anisometropia <1.50 D.+1.00 D,+1.50 D,+2.00 D,+2.50 D slasses were ware respectively for the defocus on the foundation of full correction.Dynamic visual acuity was inspected by using selfmade DVA-I training software.and static visual acuity wag tested by static visual acuity chart (Precision Vision,CAT.NO.2125).This clinical trial complied with the Helsinki Declaration and obtained the approval of Ethic Committee of Wenzhou Medical College.Written informed consent was received from each individual prior to the protocol. Results The dynamic and static visual acuities were gradually decreased with the elevation of defocus (F=506.907,P=0.000).No significant differences were found between static visual acuity and dynamic visual acuity in adult or children at various defocus(P>0.05).The regression linear analysis showed that a positive correlation between static visual acuity with defoeus(R2=0.819,t=26.72,P=0.000) or dynamic visual acuity with defoeus(R2=0.826,t=27.42,P=0.000).The slope and intercept between defocus with static visual acuity were steeper than that between defocus and dynamic visual acuity (slope:F=34.18,P=0.000;intercept:F=1005.56,P=0.001). Conclusion The effect of defocus on static visual acuity is different from that of dynamic visual acuity.It could be speculated that dynamic visual acuity is related not only to refractive systems but also other factor.

Objective To explore the difference of clinical features and laboratory indexs with different vasovagal responses in(head-up) tilt test(HUT) in children with vasovagal syncope(VVS).Methods Forty consecutive children diagnosed with VVS by HUT were analyzed.The vasovagal responses were divided into vasodepressor,cardioinhibitory and mixed patterns.The distribution and different clinical features and laboratory indexs of different response patterns in the VVS were studied.Results The most common vasovagal response was vasodepressor.There was no significant difference in their clinical features,including the motivation,presymptom,frequency and duration of syncope,baseline heart rate and blood pressure,and serum electrolytes among the children with different vasovagal respon-ses.Conclusion Vosodepressor response is the most common hemodynamic pattern in vasovagal syncope in children.

Objective To analyze blood lipid components in simple obesity children and to explore the effects of obesity in the lipid metabolism and its clinical significance.Methods A total of 90 children,including 50 simple obesity children(obesity group)and 40 normal children(control group),were enrolled in this study.The age ranged from 2.5 to 16.0 years.Their blood lipid profiles of all the children were analyzed.The blood lipid profiles were examined by biochemical analysis,including triglyeride(TG),total cholesterol(TC),low density lipoprotein(LDL) and high density lipoprotein(HDL),and the livers of all the children were analyzed.The blood lipid profiles were examined by ultrasonograph.Results 1.There were no significant differences in age and height in obesity group and control group,but there were significant differences in body mass index(BMI) and blood pressure(P0.05),which had no statistical meaning.3.Liver ultra sonogram showed that 18 cases had fatty liver(36%) in simple obesity children.Conclusions Metabolic disorder of blood lipid is present in simple obesity children,who have a tendency to get fatty liver.LDL is markedly elevated in obesity group.Arteriosclerotic cardiovascular disease should be prevented at earlier period of childhood.

Objective To study the relationship between fatty liver and blood lipids in children with simple obesity and the precaution of this disease.Methods Forty-eight cases from 2 to 16 years old with simple obesity were divided into 2 groups.The first group included 19 cases with fatty liver(38.78%);the second group included 29 cases without fatty liver(61.22%). Blood lipids in 2 groups were analyzed with biochemical method.Blood total cholesterol(TC),triglyeride(TG),high density lipoprotein(HDL) and low density lipoprotein(LDL) were detected and the liver was examined with ultrasound.Results Blood TC,TG,HDL and LDL in cases with fatty liver were higher than those wit-hout fatty liver.Blood TG had the closest relation with fatty liver(P_a

Objective To study the mRNA expression of myelin basic protein (MBP) and myelin oligodendregha glyeoprotein (MOG) in hippocampus of rats following global brain ischemia.Method The four- vessel occlusion animal model in the Sprague-Dawley rats was used in this study.The mRNA expression levels of MBP and MOG in the hippocampus of rats were analyzed by reverse transcription polymerase chain reaction (RT- PCR) at day 2,4,7,14 and 28 days after global brain ischemia.There were eight rats at each time-point and sham operated group.Results The mRNA expression of both MBP and MOG in hippocampus of rats decreased at 2 days after global brain ischemia.The gene expression of myelin gene decreased significantly at 7 days and it reached to the lowest level at 28 days.Compared with sham operated group,the gene expression of MBP and MOG in hippocampus of rats decreased significantly at 7,14 and 28 days after global brain ischemia (P

Objective To study the characteristics and clinical features of positive response during head - up tilt test (HUT) in children. Methods Forty- nine cases of syncope and aura of syncope were included in the study. All of them underwent HUT (tilt angle 60 degree,lasting 45 minutes). During the test,children' blood pressure,heart rate.electrocardiography and clinical symptoms and signs were dynamically observed. Results The common syncope aura symptoms were headache, dizziness, chest distress, difficulties in breathing, pale, perspiration, blurred vision, auditus depression and symptoms related to digestive symptoms. Among the 28 positive cases, 7 cases were of vaso - inhibitory pattern (25%), with a decrease in blood pressure and an increase in heart rate, 3 cases inhibitory pattern (11%), with a decrease in heart rate but withoilt'blood pressure changes, 4 cases mixed pattern (14 %), with decreases in heart rate and blood pressure obviously, 10 eases POTS (36%), with an increase in heart rate by 30 bpm or up to 120 bpm within 10 minutes while testing, and 4 cases orthostatic hypotension (14%), with a decrease in blood pressure within 3 minutes. Conclusion HUT can be regarded as the main tool in differential diagnosis of unexplained syncope in children.
