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 2.11.0.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

Objective To investigate the expression of Fas/FasL in children with aplastic anemia(AA) and its clinical significance.To explore the pathogenesis of AA.Methods CD34+ cell counts and the expression of Fas/FasL in 12 children with severe AA(SAA),18 with chronic AA(CAA)and 10 normal children were detected by flow cytometry combining monocolon antibody.Results The expression of Fas in children with AA were significantly higher than that in control group(P0.05).Conclusions Fas/FasL systeam take part in inducing CD34+ cell apoptosis.This may contribute to understanding the decrease number of stem cells and bone marrow failure.

Objective To explore the diagnosis of pediatric clinical hematuria disease. Methods The clinical data of one pediatric patient with IgA nephropathy combined with multiple bladder hemangioma were summarized and analyzed. Results For more than 6 years, 9-year-old female presented with repeated intermittent gross hematuria and persistent microscopic hematuria with the blood clot in urine after several respiratory tract infections. Routine urine test showed protein+++, RBC in full ifeld of vision/HP, and 0 . 54-1 . 02 g of 24 h urine protein quantitation. Early damage index of kidney is mainly based on microalbumin. The ultrasound showed no abnormal abdomen and urinary tract. Also there was no abnormality in enhanced urinary tract CT scan. Renal arteriography showed no ifstula or arteriovenous malformation. Pathological diagnosis of renal biopsy was focal proliferative IgA nephropathy. Cystoscopy examination suggested multiple hemangioma of bladder. Conclusion Bladder hemangioma is a rare condition in childhood. For children presented gross hematuria with blood clots, when the imaging ifnds no abnormalities or other diseases and the treatment of IgA nephropathy is unsatisfatry after diagnosis, the cystoscopy should be performed to exclude the possibility of bladder hemangioma.

Serum adipocyte fatty acid-binding protein (A-FABP) was raised in metabolic syndrome (MS)patients (n= 121) as compared with age-matched healthy subjects [n = 120, (14.7±4.8 vs 6.8 ±3. 0) μg/L,P<0.001]. It reached higher level in MS subjects with visceral obesity [(15.7±4.2 vs 12.6±5.1) μg/L, P<0.001]. Serum A-FABP concentration was positively correlated with body mass index, waist circumference, waist-tohip ratio, fasting insulin, homeostasis assessment for insulin resistance (HOMA-IR), fasting glucose, triglycerides,total cholesterol,and mean arterial blood pressure, whereas negatively correlated with HDL-C (r =-0. 448, P< 0.001).

Objective To analyze the risk factors for the external hydrocephalus (EH) after traumatic brain injury in the infants. Methods The clinical data of 178 cases of infants and young children with traumatic brain injury from March 2004 to April 2009 were retrospectively analyzed. Univariate and logistic regression analysis were performed to identify the clinical risk factors for EH after traumatic brain injury. Results By univariate regression analysis, age, GCS score after trauma, coma duration, brain contusion, subarachnoid hemorrhage and epilepsy were risk factors for external hydrocephalus in the infants and young children (Ps < 0.05). Gender,traumatic wet lung and usage of mannitol were less relevant to EH (Ps >0. 05). The incidence of EH after traumatic brain injury in the infants and young children was 14% (25/178 ). Age ( OR = 0.5743 ) , coma duration after trauma (OR =3.0628) ,subarachnoid hemorrhage (OR =3.7093),brain contusion(OR = 4.7892) and post-trauma epilepsy (OR =2. 9976) were risk factors for EH (Ps < 0. 05). Conclusion Younger than 2 years old, low GCS score, long coma duration, brain contusion, subarachnoid hemorrhage and epilepsy would increase the risk of EH after traumatic brain injury in the infants and young children. This study provides information for the prevention of EH after traumatic brain injury in the infants and young children.

Background One of the difficulties in identifying early glaucoma is the variability of perimetry performance.For this reason,a field defect have to be reproduced more than two consecutive examinations before it is confirmed.The relationship between visual field sensitivity and retinal nerve fiber layer (RNFL) thickness may give us a more efficient and objective assessment to the early diagnosis of glaucoma.Objective This diagnostic test was to evaluate the application of functional-structural relationship between automated perimetry and RNFL in the early diagnosis of open-angle glaucoma.Methods Sixty-four eyes of 64 patients with early open-angle glaucoma and 50 eyes of 50 normal volunteers with the matched age and gender were enrolled in Xiangya Hospital January to June 2007.Visual field examinations,including standard automated perimetry (SAP),short wave automated perimetry (SWAP),and imaging of scanning laser polarimetry with variable corneal compensation(GDxVCC),were performed on the subjects with the informed consent.The sensitivity and specificity of the joint or single measurement of GDxVCC,SAP and SWAP under the local diagnostic criteria,and overall diagnostic criteria were calculated.Results According to the overall diagnostic criteria,the sensitivity of GDxVCC,SWAP and SAP were 70％,63％,61％ respectively,and the specificity were 84％,80％,78％,respectively.According to the local diagnostic criteria,the sensitivity of GDxVCC,SWAP and SAP were 78％,86％,78％,respectively,and the specificity were 54％,40％,50％,respectively.With the local diagnostic criteria,the sensitivity and specificity of serial test of GDxVCC,SWAP and SAP were 86％ and 90％ respectively,and the positive likelihood ratio and negative likelihood ratio were 8.59 and O.16,respectively.Conclusions The functional-structural relationship between automated perimetry and RNFL which can provide valuable individual diagnostic information for patients,and serial test of GDxVCC,SWAP and SAP can reduce the false positive rate and improve the diagnostic performance significantly.

Objective To observe the changes of serum ferritin (SF)in neonates with mechanical ventilation and its clinical significance in the ventilation-induced lung injury (VILI). Methods The study was carried out in 36 neonates with mechanical ventilation and 31 neonates without mechanical ventilation in neonate intensive care unit(NICU).SF level in venous blood was measured on 1,24,48,72 hours after mechanical ventilation and 24 hours after mechanical ventilation removal by radioimmunoassay (RIA ).SF level of non-mechanical ventilation group were determined at the same time. Results SF levels in mechanical ventilation groups were significantly higher than those of control group (P

A total of 121 patients with metabolic syndrome (MS) and 120 normal subjects were recruited for exploring the association of serum adipokines with MS. The levels of resistin and adipocyte fatty acid-binding protein (A-FABP) increased, while adiponectin decreased gradually ( all P<0.05 ) in normal control group, MS without abdominal obesity group, and MS with abdominal obesity group. In MS group, resistin was positively correlated with body mass index ( BMI), waist circumference, systolic blood pressure, fasting plasma glucose, and A-FABP ( P<0.05 or P<0.01 ). Adiponectin was positively correlated with high-density lipoprotein-cholesterol and negatively correlated with BMI, waist circumference, fasting insulin, triglyceride, and homeostasis assessment of insulin resistant index.

ObjectiveTo explore the optimal method of protecting bone marrow in postoperative concurrent chemoradiotherapy of stage Ⅱ - Ⅲ rectal cancer by comparing two techniques of intensitymodulated radiotherapy (IMRT). MethodsFifteen patients with stage Ⅱ - Ⅲ rectal cancer after surgery had CT simulation. Clinical target volume, small bowel, bladder and bone marrow were contoured. Two IMRT treatment plannings with and without bone marrow-sparing (BMS-IMRT and IMRT) were separately designed. The dose distribution was compared based on that 95％ of the planning target volume received the prescribed dose. ResultsBMS-IMRT had an advantage over IMRT in terms of conformity indices ( 1. 06∶1. 04, t =- 2. 61, P =0. 023 ), but inferior to I M RT for homogeneity indices ( 0. 81 : 0. 75, t =- 2. 34, P =0.037)).Compared with IMRT, BMS-IMRT reduced the V5, V10, V20, V30, V40 of bone marrow (97.09％∶98.72％, t=-2.34, P=0.037;92.38％∶96.46％, t=-2.41, P=0.033;83.36％∶91.70％, t=-3. 18, P=0.008;51.47％∶69.65％, t=-4.92, P=0.000;36.34％∶49.57％, t=-2.66, P =0. 021 ). The doses received by small bowel and bladder were similar between BMS-IMRT and IMRT, except that the V20 of bladder was lower in BMS-IMRT (77. 32％∶92. 39％, t =-3.52, P=0. 004). Conclusions BMS-IMRT reduces low dose volume of bone marrow without increasing dose to other risk organs.BMS-IMRT might reduce acute hematologic toxicity and increase the feasibility of postoperative concurrent chemoradiotherapy in stage Ⅱ -Ⅲ rectal cancer.
