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 best MR technique for detecting small epidermoids in the cerebellopontine angle.Methods 7 patients with pathologically-proved small epidermoids only located in the cerebellopontine angle were collected. The imaging techniques included:conventional T1WI and T2WI, fluid attenuated inversion recovery(FLAIR),diffusion weighted imaging(DWI) and balanced fast field echo(B-FFE) .The findings were retrospectively analyzed.Results 6 of 7 cases of epidermoid tumours localized at the cerebellopontine angle and exhibited the similar signal intensity as the cerebrospinal fluid(CSF) on T1WI and T2WI.The remaining case was slightly isointense on either T1WI or T2WI.On FLAIR images in 6 cases,3 cases showed slightly hyperintensity, 1 case showed doubtful heterogeneous signal intensity and 2 cases did not reveal any abnormal signal intensity.3 cases were hyperintense differenting from CSF on DW images. All of seven cases showed heterogeneous signal characteristics and were quite different from CFS on B-FFE.Meanwhile B-FFE also produced clearly the tissue contrast of trigeminus embedded in epidermoids of the cerebellopontine angle.Conclusion B-FFE is much more useful for the early diagnosis of epidermoids in the cerebellopontine angle and it also can provide precise preoperative information about the trigeminus encasement.

Objective To explore the clinical significance of the brain natriuretic peptide(BNP) in evaluating the cardiotoxicity caused by daunorubicin(DNR) through studying the changes of the plasma BNP levels in children with acute leukemia who accepted the chemotherapy with DNR.Methods Thirty-one children with acute lymphoblastic leukemia(ALL) admitted in the year of 2002-2004 underwent the chemotherapy in DVLP project.The plasma level of BNP was measured by enzyme linked immunosorbent assay(ELISA) and the left ventricular end diastolic diameter(LVEDD) by color Doppler respectively before and after the administration of DNR.Simultaneously,electrocardiography(ECG) and cardiac muscle enzymes(LDH1,CK-MB) were measured as routine.Results The plasma level of BNP increased from(3.97?2.41) ng/L to(18.25?7.63) ng/L(P

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 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.

This study investigated the protective effect of ATP on skeletal muscle satellite cells damaged by H2O2 in neonatal rats and the possible mechanism. The skeletal muscle satellite cells were randomly divided into four groups: normal group, model group (cells treated with 0.1 mmol/L H2O2 for 50 s), protection group (cells treated with 16, 8, 4, 2, 1, 0.5, or 0.25 mmol/L ATP for 24 h, and then with 0.1 mmol/L H2O2 for 50 s), proliferation group (cells treated with 16, 8, 4, 2, 1, 0.5, or 0.25 mmol/L ATP for 24 h). MTT assay, FITC+PI+DAPI fluorescent staining, Giemsa staining and immunofluorescence were performed to examine cell viability and apoptosis, and apoptosis-related proteins. The results showed that the survival rate of skeletal muscle satellite cells was decreased and the apoptosis rate was increased after H2O2 treatment (P<0.01). Different doses of ATP had different effects on skeletal muscle satellite cells damaged by H2O2: the survival rate of muscle satellite cells treated with ATP at 4, 2, or 1 mmol/L was increased. The protective effect was most profound on cells treated with 2 mmol/L ATP. Immunofluorescence showed that ATP could increase the number of Bcl-2-positive cells (P<0.01) and decrease the number of the Bax-positive cells (P<0.01). It was concluded that ATP could protect skeletal muscle satellite cells against H2O2 damage in neonatal rats, which may be attributed to the up-regulation of the expression of Bcl-2 and down-regulation of Bax, resulting in the suppression of apoptosis.

Objective To investigate whether the monthly distribution of birth was associated with congenital heart disease(CHD).Methods The monthly distribution of birth of 5 070 patients with CHD who accepted examination or treatment from Jan.2003 to Dec.2006 was investigated and compared with that of 6 627 healthy newborn children born in 2001-2006.The statistic analysis was accomplished with SPSS 12.0 software for ?2 test.Results Four hundred and forty-four of the 5 070 patients with CHD were born in January(8.8%),432 cases in February(8.5%),384 cases in March(7.6%),339 cases in April(6.7%),390 cases in May(7.7%),393 cases in June(7.8%),414 cases in July(8.2%),489 cases in August(9.6%),498 cases in September(9.8%),492 cases in October(9.7%),396 cases in November(7.8%),and 399 cases in December(7.8%).The structural ratio of the number of CHD patients were the highest for those who were born in August,September,October,and the lowest among those who were born of February and March,April.The number of CHD patients who were born in the autumnal months of August,September and October was 1 479(29.1%),much higher than those who were born in February,March and April(1 155 cases,22.8%)(P
