[Objective]To study the properties of xenogeneic deproteinized bone (DPB) used as scaffold in the bone tissue engineering and its application to the spinal fusion of the lumbar intertransverse process in a goat. [Methods]The deproteinized bone was derived from an adult pig femoral cancellous bone through physical and chemical treatments.The cell-material complex was observed under the inverted phase contrast microscope to evaluate the adhesion and the growth of the osteoblasts. The experimental model of the spinal fusion in the lumbar intertransverse process was produced in 24 male goats aged 6-8 months, which were divided into 3 groups according to different implant graft. All the samples were harvested at 4,8,12 weeks postoperatively, and a series of examinations were performed, including the radiography and the histomorphological assay.[Results]It showed that The DPB maintained natural pore network system, it hardly had any antigen, so it had good histocompatibility. In the spinal fusion model of lumbar intertransverse process,the cell-material complex could form cartilage and had a new bone formation in a multipoint way, the osteogenic process was almost the same as the auto-ilium osteogenesis and had a good mechanical strength.[Conclusion]The xenogeneic deproteinized bone is a good material in the bone tissue engineering, which can be used as an osteogenesis scaffold and provides a stable fusion.

ObjectiveTo investigate preliminary applic ation values of intravascular ultrasound(IVUS)in the carotid artery narrowing of transient ischemia attack (TIA) patients. MethodsIVUS has been used to 4 TIA patients with carotid artery narrowing identified by carotid artery echo, following carotid stenting and completion angiogram to detect evidence of inappropriate stent deployment. ResultsIVUS revealed the vessel wall structure, plaque morphology, measured accurately the narrowing degree of carotid artery. The narrowing percent identified by IVUS was larger than angiogram, and IVUS was more sensitive in detecting plaque than digital subtraction angiography(DSA). Four patients accepted stent deployment successfully.ConclusionsDSA underestimated the severity of the lesion. IVUS more accurately evaluates the extent and characteristics of the lesions than DSA, it is an important and useful component of carotid artery stent procedures.

Objective To summarize the onset and the management of serious responsiveness during the tilt table test (TTT), and the prevention measures. Methods Thirty six elderly patients (26 males and 10 females, aged between 60 70) were tested with a tilt angle of 70 degrees for a maximum of 45 minutes and then processed with isoproterenol provocative tilt testing. ECG and blood pressure were monitored during the test and the peripheral intravenous cannula were maintained for all patients with normal saline. Results Twenty one of the 36 patients were defined as positive including 10 showing serious responsiveness. Of the 10 patients, 3 had a history of atherosclerosis involving internal carotid arteries; among the 3 with bradycardia, 2 were associated with II? A V block, and another one was with chronic atrial fibrillation. The serious reponsiveness included asystole for more than 5 seconds(3 cases) , serious bradycardia for more than 1 minute(3 cases) , and serious hypotension for more than 1 minute (4 case), respectively. Those with serious responsiveness were managed with returning to supine position, or intraveneous atropine, or CPR (2 cases), or oxygen given(4 cases). Only 2 hypotensive patients recovered gradually in 10 minute emergent management while others recovered rapidly and with no complication. Conclusions TTT may result in serious responsiveness especially in elderly patients though it is non invasive method. Therefore, proper patient selection according to the indications, control of isoproterenal infusion and close observation of vital signs are important for a safe consequence.

Objective To explore the relationship between the serum level of leptin,growth hormone(GH),insulin like growth factor-1(IGF-1),insulin like growth factor binding protein-3(IGFBP-3)and those modulatine effects on fetal growth.Methods One hundred and thirty-five cases of newborns were divided into 4 groups according to the relationship between born weight and gestational age.Group A:premature infants small for gestational age(SGA),n=30.Group B:premature infants appropriate for gestational age(AGA),n=36.Group C:mature infants small for gestational age,n=32.Group D:mature infants appropriate for gestational age,n=37.All infants were measured se-rum leptin,GH,IGF-1 and IGFBP-3 level with radiommunosassay(RIA).Results There were significant difference in the levels of leptin,GH,IGF-1,IGFBP-3 as group C0.05).There were positive correlation between levels of leptin,IGF-1 and IGFBP-3 in group A,B and C,while,there was positive correlation between only level of IGF-1 in group D.Conclusions Leptin,IGF-1 and IGFBP-3 may play an important role in the fetal growth regulation of premature infants and IUGR infants.IGF-1 also regulate intrauterine growth of group D.Another side,in group D,Leptin,GH,IGF-1 and IGFBP-3 don't regulate fetal growth.

BACKGROUND:Heterogeneous deproteinized bone because of wide source and its special biological characteristics maybe a good bone tissue engineering scaffold.Its immunogenicity and mechanical properties are different by different interventions.OBJECTIVE:To proof the preparation technology,immunological and mechanical properties of heterogeneous deproteinized bone.DESIGN,TIME AND SETTING:A control observational experiment was performed in the Heilongjiang Key Laboratory of Anti-fibrosis Biotherapy from February to October 2008.MATERIALS:Fresh femoral cancellous bones extracted from adult pigs,which were not including cartilages and cortical bones,were prepared into size of 3 cm?0.5 cm?0.5 cm.Their long axis direction was the same with orientation of trabeculae.The apparent pore densities of the used bones were almost same.METHODS:The bones were soaked in chloroform-carbinol(1:1) 24 hours for degrease.They were shaken and washed by distilled water at 50 ℃,and then put into 20% H2O2 for 24 hours.The procedure repeated three times.The bones were soaked in distilled water at room temperature for 24 hours,and then dryed.MAIN OUTCOME MEASURES:The gross morphological and histological features of the deproteinized cancellous bones were observed.The contents of amino acid and their biomechanical properties were measured.RESULTS:The three-dimensional space structures of the deproteinized cancellous bones were not damage greatly,and they had a natural pore network system which composited of hydroxyapatite and collagen.The contents of collagen amino acids in the deproteinized cancellous bones had no obvious difference from fresh cancellous bones,but the wave crests of aromatic amino acids such as tyrosine and methionine were disappear.The elastic moduli of deproteinized cancellous bones were significantly higher than those of fresh cancellous bones(P

AIM To explore the effects of trip-tolide on endothelin-1 and its gene expression in lung of asthmatic guinea-pigs. METHODS The contents of ET-1 in lung of asthmatic guinea-pigs were measured with radioimmunoassay, and the expressions of ET-1, ETA, ETB and ECEmRNA with reverse transcription DNA polymerase chain reaction (RT-PCR). RESULTS 0 All of the indexes were increased after guinea-pigs were induced asthma. At the 4th hour after first induction of asthma, ET-1 reached the top, but at the 2rd hour, ET-1mRNA, ETAmRNA and ECEmRNA were markedly higher than control group (P

Chromoblastomycosis, a chronic fungal infection of the skin and subcutaneous tissue, is known to be difficult to treat. Recently itraconazole has proved effective for treatment of this infection, but requires a prolonged treatment course. We experienced a case of chromoblastomycosis caused by Fonsecaea pedrosoi in a 68-year-old Korean man showing a complete resolution with a short course of oral itraconazole, 200 mg daily, for six weeks.
