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).

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.

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.

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.

Objective To confirm the association between the“Tip-Apex Distance (TAD)”and cut-out of the lag screw from the femoral head.and to analyze other factors leading to the cut-out.Methods The complete radiographic and clinical data of 106 patients with femoral intertrochanteric fractures were available for this study. They were 65 men and 41 women,with an average age of 52.4 years (range,20 to 83 years).According to Evans classification.19 cases belonged to typeⅡ.25 to typeⅢ,32 to typeⅣ,29 to typeⅤ,and one to type R.The bone quality was classified by Singh rating system:44 cases were rated as typeⅥ.34 as typeⅤ,23 as typeⅣand five as typeⅢ.They were treated with open reduction and fixation with 135?dynamic hip screw (DHS).According to the finding of Baumgaertner that“TAD”beyond 25 mm would grcatly increase the risk of cut-out,the patients could be divided into two groups:59 cases with“TAD”less than 25 mm and 47 greater than 25 mm.Results The mean duration of follow-ups was 14.45 months (range,4.5 to 28.0 months).Of the 15 cases whose“TAD”was more than 30 mm,one had the cut-out.Of the seven cases whose“TAD”was more than 40 mm,two had the cut-out (P=0.000). The average age of the three patients was 78.7 years (range:75 to 83 years) and 27.1 years older than that of the 103 patients whose fracture healed (P=0.000).They belonged to the unstable intertrochanteric fracture of the femur (two to Evans type V and one to type R).The reduction was assessed as excellent in 43 cases,good in 47 cases,fair in nine cases (of whom one had the cut-out),poor in seven cases (of whom two had the cut-out). Conclusions The cut-out of the lag screw from the femoral head can be caused by age,fracture type and stability of reduction and“TAD”.The greater the“TAD”value,the greater possibility of cut-out.
