Objective To explore the clinical modalities and diagnosis of respiratory failure due to laryngotracheal disorders in children,in order to reduce the misdiagnosis.Methods Fifteen patients(11 cases were male,4 cases were female) with respiratory failure in Intensive Care Unit, Tianjin Children′s Hospital from Jul.2006 to Jul.2009 were selected.Data including history,characteristics and results of spiral computerized tomography(CT) and reconstruction and magnetic resonance imaging(MRI) were reviewed.Results The major clinical manifestations indicated that 7 cases had laryngeal stridor,6 cases had recurrent pneumonia,5 cases had cyanosis after crying,and 12 patients were complicated with respiratory failure in 12 hours.Nine cases were recovered,3 cases were given up,and 3 cases died.All patients were performed with CT about laryngohypopharynx,and the results were cyst of root of tongue in 3 cases,trachea pressed by cyst of parapharyngeal space in 1 case.There were 11 cases examined by spiral CT and reconstruction,in which 6 cases were confirmed as tracheal stenosis,2 cases were left bifid tracheostoma,2 cases were pulmonary artery sling,and 1 case was diagnosed as tracheomalacia.Chest X-ray radiograph indicated that bronchopneumonia in 8 cases,bronchitis in 3 cases and negative in 4 cases.Echocardiograph examination was performed among 11 cases,in which 2 cases were pulmonary artery sling,2 cases were atrial septal defect,1 case was patent ductus arteriosus, and 6 cases were negative.Conclusions There is high morbidity of respiratory failure caused by laryngotracheal disorders in infants,but misdiagnosis ccures usually because of non-specific symptoms.If the infant must depend on mechanic ventilation for a long time and has airway obstruction,he should be examined early by using spiral CT.

AlM: To study the effects of different concentrations of Coix seed oil on human retinal capillary endothelial cells ( HRCECs ) proliferation and vascular endothelial growth factor ( VEGF) expression in high glucose environment.
METHODS: HRCECs extracted from human fresher eyeball and cultured in vitro, and ultimately used in the experiment were the growth of 3rd ~ 4th cells, the experimental were divided into blank control group, low glucose control group, high glucose control group, high glucose + ( 50ü L/mL, 100ü L/mL, 200ü L/mL ) different concentrations Coix seed oil group. Detecting the multiplication of HRCECs by MTT, the immunocytochemical method was employed to detect the each group HRCECs of VEGF expression.
RESULTS:MTT assay results showed that: different concentrations of coix seed oil acted at HRCECs for 48h, inhibition of cell proliferation was significant difference compared with high glucose control group (P<0. 05). Within 48h showed concentration dependence. There was no statistical difference between the low glucose group and high glucose control group (P>0. 05). lmmunocytochemical assay showed that:50ü L/mL, 100ü L/mL, 200ü L/mL Coix seed oil acted at HRCECs 48h, the expression of VEGF decreased significantly compared with the high glucose control group ( P< 0. 05 ), and in a dose- dependent manner. However, in high glucose control group, the expression of VEGF was obvious higher than that of low glucose control group (P<0. 05).
CONCLUSlON:Coix seed oil can inhibit the HRCECs proliferation and suppress the VEGF expression in high glucose environment.

AIM:To evaluate the clinical characteristics in retinal nerve fiber layer ( RNFL) thickness of the 8~17 years old near sightedness, provide the basis for juvenile glaucoma diagnosis, to avoid missed diagnosis and misdiagnosis.
METHODS:A total of 165 eyes from 99 healthy subjects ( age range 8 ~ 17 years ) were divided into low, moderate, high myopia and normal group. Cirrus HD OCT was used to measure the RNFL thickness. Each subject was performed circular scans around the optic nerve with a circle size of 3. 46mm. Total average, mean quadrant and clock - hour RNFL thicknesses were recorded and compared between the four groups. The characteristics of the RNFL thickness of myopia were observed.
RESULTS: Compared myopia groups with normal group, the mean RNFL thickness decreased, there was statistically significant difference in high myopia group (P<0. 05). The mean RNFL thickness of superior, inferior and nasal quadrant decreased, temporal quadrant was thickened. Compared moderate and high myopia groups with normal group, superior, inferior quadrant RNFL thickness were thinning, temporal quadrant was thickening, the differences had statistical significance ( P< 0. 05 ). The RNFL measurements were statistically significant thinner in the myopia groups compared with normal group at 1:00, 5:00, 6:00 and 12:00 o'clock ( P<0.05) and thicker at 8:00, 9:00, 10:00 o'clock (P<0. 05). The RNFL measurement was statistically significant thicker in the low myopia group compared with normal group at 3:00 o'clock (P<0. 05).
CONCLUSION: Compared adolescent myopia with normal, the Avg ( mean RNFL thickness ) , S ( superior quadrant RNFL thickness ) , I ( inferior quadrant RNFL thickness), 1:00, 5:00, 6:00 and 12:00 o'clock RNFL thickness is thinner, which is decreased with the increasing SE. While the temporal ( T) quadrant, 8:00, 9:00, 10:00 o'clock RNFL thickness is thicker, which increased with the increasing SE. Analysis of RNFL thickness in the evaluation of glaucoma should always be interpreted with reference to the refractive status, so as not to cause misdiagnosis of glaucoma. The highest diagnosis efficiency position of glaucoma is infratemporal (7:00~8:00 o'clock) and superior temporal (10:00 ~11:00 o'clock), which is not thinner in juvenile myopia, if these positions become thinner, it may be the possibility of glaucoma.

OBJECTIVEThe clinical effect of the Shi's cervical reduction technique for cervical spondylosis and related disorders has confirmed, however, there were few studies on the body motion during manipulation in vivo study. This study is to summary the law of motion and the motion characteristics of the right operation shoulder, elbow, knee and ankle joints by data acquisition and analysis with the 3D motion capture system.
METHODSThe markers were pasted on the head, trunk, left and right acromion, elbow joint, wrist joint inner side and the outer side of the inner and the outer side and the lateral upper arm, forearm lateral, anterior superior iliac spine, posterior superior iliac spine, trochanter, femoral and tibial tubercle, inner and outer side of knee, ankle, fibular head, medial and lateral in first, 2,5 metatarsal head, heel and dual lateral thigh the calf, lateral tibia of one manipulation practioner, and the subject accepted a complete cycle of cervical "Jin Chu Cao and Gu Cuo Feng" manipulation which was repeated five times. The movement trajectory of the practioner's four markers of operation joints were captured, recorded, calculated and analyzed.
RESULTSThe movement trajectories of four joints were consistent, while the elbow joint had the biggest discrete degree. The 3D activities of the shoulder and elbow were more obvious than other two joints, but the degree of flexion and extension in the knee was significantly greater than the rotation and lateral bending.
CONCLUSIONThe flexibility of upper limb joint and stability of lower limb joint are the important guarantees for the Shi's cervical reduction technique, and the right knee facilitated the exerting force of upper limb by the flexion and extension activities. The 3D model built by the motion capture system would provide a new idea for manipulation teaching and further basic biomechanical research.

Antheraea pernyi nucleopolyhedrovirus (ApNPV) PstI-B and C fragments were cloned and sequenced. ApNPV PstI-B was 7406 bp long, contained seven open reading frames (orfs)/genes, including p87, he65, pnk/pnl, odv-ec43 and Orgyia pseudotsugata multicapsid nucleopolyhedrovirus (OpMNPV) orf107,orf108 homologue on either strands of genomic DNA. ApNPV PstI-C was 6663 bp long, contained eleven orfs/genes, including pk-1, orf1629, polh, lef-2, ptp-2, ctl-1, ptp-1 and OpMNPV orf5, orf7, orf8, orf1 1 homologue on either strands of genomic DNA. Among the eighteen baculovirus genes identification, he65 and orf1629 were two diverse genes, while polh and lef-2 were two conserved genes. ApNPV was the third baculovirus found to contain pnk/pnl gene, the fourth baculovirus found to contain both ptp-1 and ptp-2 gene.
