Objective To screen for the causative genes involved in the occurrence and development of minimal changes nephritic syndrome(MCNS) and to furtherly assist the genetic diagnosis and treatment of MCNS.Methods Human genome U133 Array Set from Affymetrix Inc was used to evaluate gene expression patterns in peripheral blood mononuclear cells(PBMC) isolated from 7 children with primary MCNS and 7 age-matched health volunteers.Reverse transcription-polymerase chain reaction(RT-PCR) and real-time PCR were performed to identify the findings of gene chip.Results Of 33 000 genes detected,969 genes showed significant difference between children with(MCNS) and healthy volunteers;552 genes were up-regulated,while 417 genes down-regulated significantly.Findings from RT-PCR and real-time PCR were consistent with those of gene chip.Conclusions Gene chip of expression patterns is a powerful method to detect expression difference of genes correlated with MCNS.Occurrence and development of MCNS can be a complicated process that many correlative genes may participate in.

Objective To study the clinical values of positron emission tomography(PET)in pre-term and term newborn infants through observing neonatal brain by 18F-fluorodeoxyglucose(18F-FDG)PET.Methods The brain by 18F-FDG PET in 11 term and 7 pre-term newborn infants after administration of 0.1 mCi /kg 18F-FDG were observed.There were 11 males and 7 females,who were normal by brain computed tomography or magnetic resonance imaging.Results The brain 18F-FDG PET image in pre-term and term newborn infants was relatively high in thalamus,and relatively low in cerebral cortex,whereas the total brain was different with adults.Especially in the area of cerebral cortex,the uptake of glucose was relatively higher,and the structure of brain 18F-FDG image was more clear in term infants than that in pre-term infants.Conclusion Neonatal brain picture by 18F-FDG PET is a new tool for predicting the brain function,and its clinical values need further investigating.

Objective To explore the changes of positron emission tomography(PET)in newborn infants with HIE through 18F-fluorodeoxyglucose(18F-FDG)and it's significance.Methods Eleven healthy newborn infants and 8 newborn infants with HIE were selected.Among the healthy newborns,7 cases were male and 4 cases were female,and the mean birth-weight was(3 350?620)g,the gestational age was(37.9?1.3)weeks.Among the HIE neonates,5 cases were male and 3 cases were female,and the mean birth weight was(3 180?390)g,the gestational age was(37.1?2.4)weeks.There were no significant differences of sex and gestational age between the 2 groups.The examination time was form 3 to 21 d,and the mean age was(8.7?3.9)d.PET of the children in 2 groups were observed after 0.1 mCi/kg 18F-FDG injected 30 min.Results The brain 18F-FDG PET image in newborn infants was relatively high in thalamus,and relatively low in cerebral cortex,whereas the total brain was different with that of the adults,and that was not as clear as that of adults.Especially in the area of cerebral cortex,the uptake of glucose was relatively higher.The structure of brain 18F-FDG image was significantly changed in newborn infants with HIE,especially increased in the areas of peripheral ventricle and hypophloeodal cerebral white matter,and there was a remarkably bilateral asymmetry.Conclusions Neonatal brain picture by 18F-FDG PET is a new tool for predicting the brain function,and its clinical values need further investigating.

In this study, a recurrent massive phyllodes tumor of the breast was surgically removed and the grafting was used to repair the local skin defects. A 29-y female patient had recurring breast phyllodes tumor of extremely large size in the chest wall after the excision of a previous tumor. The massive phyllodes tumor was eliminated by completely removing the layers of the skin and tissues above the costal bones with incisal margin being 2 cm away from the tumor lesion. The latissimus dorsi myocutaneous flap, lateral thoracic skin flap, and rectus abdominis myocutaneous flap were grafted to replace the lost tissues due to the surgery. Anti-infection and anticoagulation treatments were used after the surgery. The graft flaps had sufficient blood supply and good blood circulation, and the incisions mostly healed. The outcome of the surgery was acceptable. For the surgical treatment of the massive phyllodes tumor in the chest wall, it is an alternative of choice to use latissimus dorsi myocutaneous flap, lateral thoracic skin flap and rectus abdominis myocutaneous flap in combination for skin grafting.

To solve the issues of costly planting of facility cultivation method and inferior efficacy than wild herbs of Dendrobium officinale, the cliff epiphytic cultivation method was studied. To research the growth, agronomic traits, yield, polysaccharide and alcohol-soluble extract contents were measured on the D. officinale from different water regulation and cliff slope gradients treatments. The results showed that D. officinale epiphytic at 85 degrees-90 degrees cliff and sprayed water 1-2 h x d(-1) at the growing season can get better growth and obtain high yield, and the morphology has no different from wild cliff D. officinale, even in the environments without shade. The contents of polysaccharide and alcohol-soluble extract are closely related to the physiological ages, but significantly higher than the facility cultivation. It is possible that environmental stresses benefit the accumulation of polysaccharides, alcohol-soluble extract and other efficient ingredients.

OBJECTIVETo investigate the role and clinical value of radionuclide imaging in hepatic impact injuries in rabbits.

METHODSRabbits were experimentally impacted on the liver with BIM-IV bio-impact machine. Liver imaging was performed with 99mTc labeled sodium phytate. Liver blood pool imaging was performed with 99mTc-stannous pyrophosphate labeled red blood cells. The results of radionuclide imaging were compared with the anatomic results.

RESULTSThere was significant difference between the images of the injured liver and the control. Radio diminution and defect were shown in the injured liver areas. Various sorts of abnormal radioactivity distribution were observed with hepatic blood pool imaging. The results of the liver imaging and liver blood pool imaging were accorded with the results of the anatomic findings.

CONCLUSIONSRadionuclide imaging may well display the changes of hepatocellular structures and functions after injury, which is valuable in locating the concrete injured position and differentiating the injured degrees of liver.

OBJECTIVEUsing MBEC-Assay to assay minimal biofilm eradication concentration (MBEC) of Galla Chinensis and Nidus Vespae to oral bacterial biofilm. To set up traditional Chinese medicine susceptibility pharmacodynamic empirical study methods of oral bacterial biofilm.

METHODSCariogenic bacteria strains were selected (Streptococcus mutans ATCC 25175, Streptococcus sanguis ATCC 10556, Lactobacillus rhamnosus AC 413, Actinomyces naeslundii WVU 627) in this study. Extraction components of Galla Chinensis were GCE (aqueous extract), GCE-B (30% alcohol extract) and extraction components of Nidus Vespae were NVE1 (95% alcohol extract). (1) To observe oral bacterial biofilm formatiom in MBEC-Device at different time. (2) MBEC-HTP-Assay: The minimal inhibitory concentration (MIC) and minimal biofilm eradication concentration (MBEC) of GCE, GCE-B and NVE1 to oral bacteria strains were determined.

RESULTSOral bacterial biofilm were readily formed on the lid of MBEC-Device under selected condition (observed by SEM). Oral cariogenic bacteria growing as plankton populations were sensitive to GCE, GCE-B and NVE1. To GCE, GCE-B and NVE1, oral cariogenic bacterial biofilm were 2-16 times less susceptible than growing plankton bacteria. GCE and GCE-B were the most effective medicine against oral cariogenic bacterial biofilm. NVE1 were effective in killing oral-bacterial biofilm at relatively high concentration.

CONCLUSIONGCE and GCE-B were effective medicine against oral cariogenic bacterial biofilm. MBEC (minimal biofilm eradication concentration) can provide a relative accurate medicine concentration for clinical test.
