Objective To study the situation of pathogenic bacteria of neonate infection in hospital,so can guide clinical doctors use antibiotic rationally. Method The secretions of 159 neonates′ umbilous and eye matter orders were collected to be used as the specimen and the drug susceptibility experiment was done using MIC and K-B methods together in 159 neonates with hospital infection.Results One hundred and eighty-nine pathogenic bacterias were isolated from 1613 specimens.According to our materials,staphylococci aureus was the most important pathogenic bacteria,then staphylococci heamolyticus,staphylococci epidermidis,encherichia coli ,enterobater cloucac ,klebsiella pneumoniae.MRSA- positive rate was 52.6%,ESBLs-positive in E coli was 21%,inklebsiella pneumoniae was 20%.Drugs of sensitivity for Gram positive coccus were vancomycin(0) clindamycin(8.5%) cipnofloxacin(12.2%);the drugs of sensitivity for Gram negative ord were imipenem (4.4%),cipnofloxacin(5.3%),amikacin(12.7%).Conclusion It is instructive that use antibiotic rationally for controlling neonate infection in hospital.

Objective To compare pediatric patients with periventricular leukomalacia (PVL) with normal children by using diffusion tensor MR imaging. Methods Diffusion tensor images were obtained in 15 pediatric patients with PVL and 15 age-matched normal children. Regions of interest were drawn to measure the fractional anisotropy (FA) in bilateral posterior limb of internal capsule, bilateral optic radiation, genu of corpus callosum, and splenium of corpus callosum. The values of PVL patients and normal children were compared using non-dependent samples T-test. Results The FA values of regions of interest prescribed were significantly lower in PVL patients than in normal children(P

Objective To study the normal changes in brain white matter during childhood by analyzing the anisotropy of different regions and different age groups with diffusion tensor imaging (DTI). Methods DTI was performed in 89 children (age range from 2 days to 18 years) without brain abnormalities, and the data measured in fractional anisotropy(FA) maps were analyzed statistically. Children less than 6 months were ranged to group 1, 6-12 months to group 2, 1-3 years to group 3, 3-5 years to group 4, 5-8 years to group 5, 8-12 years to group 6, 12-18 years to group 7. Results (1) There were significant differences in anisotropy (FA values) among different regions of white matter in brain In group 7, the FA value of corpus callosum was 0.826?0.039, middle cerebellar peduncle 0.678?0.043, frontal white matter 0.489?0.033. (2) The anisotropy among different age group was statistically different, P

To assess the effect of prostaglandin E_1(PGE_1)on renal blood flow and serum endothelin of liver recipients.Methods PGE_1 was administered in 38 liver recipients at the dose of 0.6?g?kg~(-1)?h~(-1)during liver transplantation and every day after operation.The effects of PGE_1 on serum endothelin concentration and creatinine(Cr)were observed and these indexes were compared with those in the control group(n=18).The renal blood flow resistance indexes(RI)were measured by Doppler ultrasound.Results Cr and RI were significantly lower in PGE1=treated group than those in the control group.PGE_1-treated group also showed a significantly lower serum endothelin concen- tration.Conclusion Administration of PGE_1 in liver recipients can significantly improve the early re- nal function by reducing serum endothelin concentration and dilating renal blood vessels.

Objective To study the normal changes in brain during childhood by analyzing the diffusion characters of different regions and different age phases with diffusion tensor imaging (DTI). Methods DTI was performed in 63 children (age range, 2 days to 9 years) without brain abnormalities and the data measured in ADC maps were analyzed statistically. Results (1) There were significant differences in ADC values among some different regions of brain tissue; (2) In babyhood, the ADC values in gray matters decreased faster than in white matters; (3) The ADC values decreased with the increasing of age , and show negatively exponentially correlation with age. Conclusion DTI shows the changes of brain tissue composition in vivo, with which normal changes in brain during childhood can be evaluated.

Objective To study findings of the white matter of nomal children on color tensor map and evaluate the diffusion tensor imaging in the assessing development of the brain. Methods DTI was obtained in 89 normal children aging from 2 days to 18 years.Their color tensor maps were generated and analyzed.Results Their color tensor maps revealed different findings due to aging;with the increase of the age,the fiber tracts showed were more and well defined.Conclusion The color tensor map is superior to the routine MR in assessing the development of the white matter.
