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

Identification and classification of white blood cells are important for clinical diagnosis.Many researchers have been seeking the effective methods for white blood cells' automatic classification based on morphological characters.After cell segmentation,leukocytes' feature acquirement and selection,this paper accomplishes white blood cells' automatic classification using Sugeno-model fuzzy neural network and compares the result with that from classifier of BP network.

Objective:To study the isolation, culture and identification of the TMJ cells and to observe the biological characteristics of cultured fibrochondrocytes. Methods:The TMJ discs were dissected from two 1 month goats under sterile conditions and were digested with collagenase. The cells were collected. Morphological changes and attachment efficiency were constantly observed under phase-contrast microscope. Immunohistochemical staining for type I collagen as well as toluidine blue staining were performed. Ultrastructures of the TMJ cells were observed under transmission electron microscope. Results: Most of the primary fibrochondrocytes presented a short spindle-shape while the rest showed polygon-shape. On the 7th day, the perliferating fibrochondrocytes started to contact each other to form a monolayer covering the bottom of the incubation disc. Immunohistochemical staining of type I and toluidine blue staining exhibited positive results. The fibrochondrocytes cytoplasms were rich in mictochondria and endoplasm reticulum. Conclusion: The fibrochondrcytes isolated from one-month-old goat TMJ disc have good proliferation ability in vitro and cells from passage 1 to 3 might be used as seed cells for TMJ disc tissue engineering.

BACKGROUND:There is no common cognition in the cell type in the temporomandibular joint(TMJ)discs,and names describing TMJ disc cells also vary a lot.OBJECTIVE:To characterize the type and the distribution of cells in the TMJ disc of goats DESIGN,TIME AND SETTING:A single sample observation was completed in Cettutar and Motecutar Biologicat Center and Electron Microscope Center of Lanzhou University from March to May in 2007.MATERlALS:TMJ discs were obtained from two one-month-old healthy goats that were slaughtered freshly.METHODS:Bilateral TMJ discs of goats were cut off completely and were divided into 6 parts by 3 cuts in the major axis direction (mediolaterally)and 2 cuts in the minor axis direction(anteroposteriorly).Then the marked samples were fixed in 10%neutral formalin Iiquid for 24 hours and embedded by paraffin.MAIN OUTCOME MEASURES:Hematoxylin and eosin staining were used to identify regional variation of cell type and cellnumbers.Toluidine blue staining and collagen type Ⅰimmunohistochemical assay were performed to test the distribution of collagens.Transmission etectren microscopy was used to observe the ultrastructure of cells of goat TMJ discs.RESULTS:TMJ discs were comprised of cells and collagen fibers distributing unevenly.Collagens were mostly type Ⅰ.Collagen fibers were wave or crimping and approximately parallel to each other.with cells scattered in their matrix.Fibroblast-like cells and chondrocyte-like cells were the main two types of cells existing,with the former predominating over the later in a ratio of 2.05:1 approximately.There were no significant regional differences in cell type and distribution statistically.Transmission electron microscopy denoted that fibroblast-iike cells have fairly larger fusiform or irregular nuclei with very few organelles,while the chondrocyte-like cells exhibited round or elliptical nuclei,well defined pericellular electron lucent zones,unconspicuous cytocysta and non-distinctive pseudopodia CONCLUSION:There are no significant differences in type,number and arrangement of cells in TMJ discs of one-month-old goats statistically,with Fibroblast-like cells predominating slightly over chondrocyte-like cells.

Objective To study the screening value of color doppler flow imaging (CDFI) for gastroesophageal reflux(GER).Methods Through the window of left lobe liver, the abdominal esophageal length,the phenomenon of GER and the frequency of GER were detected by CDFI in 55 children with GER and 55 control group.Results Abdominal esophagus was identified by CDFI in every children. The abdominal esophageal length was shorter in refluxers than that in control group. A significant correlation was found between its length and the age of control group.To diagnose GER with CDFI ,its accuracy was 98.18%,and its specificity was 76.36%.Conclusions Visualization and measurements of the abdominal esophagus are readily achieved with CDFI in children.Abdominal esophageal length is shorter in refluxers than that in control group. CDFI is a rapid method of screening GER.

Objective To study whether gastric liquid emptying is delayed in children with gastroesophageal reflux and its clinical significance. Methods At different times after meal, the gastric antral diameters were measured by real - time ultrasonography in 55 children with gastroesophageal reflux and 55 controls. Results At 20 min,60 min after meal , there was a significant difference in gastric emptying rate between case groups and control groups, respectively(P
