Objective To evaluate the value of CT and MRI in diagnosis and directing clinical management of vertebral burst fracture.Methods The imaging features of vertebral burst fracture in 66 cases were analyzed,including cervical vertebrae 6,thoracic vertebrae 3,thoracolumbar area 48,and lumbar vertebrae 9 cases.There were 50 male and 16 female,the average age was 35 years.CT and MRI were taken in all patients.Results CT clearly demonstrated the vertebrae and accompanying appendix fracture,spinal canal stenosis and retropulsed fragment.While MRI in showing injury and tear of ligament and intervertebral disc,abnormal signals due to spinal cord compression were superior to CT.Conclusion CT in combination with MRI in diagnosis and directing surgical management is of important value.

Objective To reveal the effects of cold-dryness and modified Zhisou Power on epidermal growth factor receptor (EGFR) and neutrophil elastase (NE) in rats with COPD. Methods COPD model was established with an elastase dose into the trachea combined with exposure to smoking for 90 d; cold-dryness COPD group was further developed by exposure to a cold, dry environment for 90 d. After 90 days, cold-dryness COPD rats was divided into cold-dryness group and Zhisou Power intervention group (treated with modified Zhisou Power for 7 days). On the 97th day, all rats were killed. Pathological changes in lungs were observed. mRNA and protein expression of EGFR were measured by RT-qPCR and Western blot, and the amount of NE in serum and BALF were examined by ELISA. Results EGFR mRNA and protein expression were significantly higher in COPD group, cold-dryness group and Zhisou Power intervention group than in control group. EGFR was significantly lower in Zhisou Power intervention group than in COPD group and cold-dryness group. NE was significantly higher in serum and BALF in COPD group, cold-dryness group and Zhisou Power intervention group than in control group. NE in BALF was significantly higher in cold-dryness group than in COPD group. NE in BALF was significantly lower in Zhisou Power intervention group than in cold-dryness group. Conclusion Modified Zhisou Power can down-regulate the expression of EGFR and the mount of NE in cold-dryness COPD rats to treat COPD.

OBJECTIVETo observe Modified Zhisou Powder (MZP) on the lung function of chronic obstructive pulmonary disease (COPD) model rats of northwest China cold dryness syndrome (NCCDS).

METHODSTotally 90 male Wistar rats were randomly divided into three groups, i.e., the normal control group (n =20), the COPD model group (n =35), and the COPD of NCCDS group (n =35). The COPD model was established by tracheal dripping porcine pancreatic elastase (PEE) in combination with fumigation for 90 days. The COPD of NCCDS model was set up by tracheal dripping PEE +fumigation + cold and dry environmental stress for 90 days. Then rats in the COPD of NCCDS were randomly divided into the MZP intervention group (n =11 )and the normal saline intervention group (n =10).All intervention lasted for 15 successive days. The lung function was detected using Small Animal Lung Function Device at day 90 and day 105. And the lung pathology was also observed.

RESULTSLittle amount of sputum sound could be heard in the airway of the COPD model group and the COPD of NCCDS group. Pathological section showed alveolar ectasia, narrowed and broken alveolar septa, forming larger capsular space with infiltration of inflammatory cells. Rats in the COPD of NCCDS group showed chills, increased amount of drinking water, and loose stool. MZP could improve their symptoms. As for lung function test, compared with the normal control group, Te increased in the COPD model group (P <0.01), and EF50 decreased (P<0.05). PEF and EF50 decreased (P <0.01), Ti and Te increased (P <0.01, P <0.05) in the COPD of NCCDS group. Compared with the normal saline intervention group, PEF and EF50 increased (P < 0.01), Ti and Te decreased (P <0.01) in the MZP intervention group.

CONCLUSIONMZP could improve the symptoms of COPD rats of NCCDS, and delay the velocity of decreased lung function.

Objective To evaluate the clinical outcomes of a hovel porous β-tricalcium phosphate (β-TCP)and control allograft for the repair of lacunar bone defects caused by solitary bone cyst curettage.Methods From January 2003 to December 2008,the patients with solitary bone cyst were randomized into an experimental(55 cases)and a control(40 cases)group.The control group received particulate allograft bone as the graft material,and the experimental group received β-TCP.At 1 week,1,2,3,6,12,24,48months after surgery,a new radiographic scoring system was employed to calculate the biodegradation of bone graft and evaluate the influence of multiple factors.Histologic characteristic of the degradation process of β-TCP were also evaluated.Results All the cases were followed up for average 28.4 months.Radiographic semi-quantitative analysis revealed that the biodegradation effieiencies were not significantly difierent between β-TCP and allografts(P=0.424).Degradation percentage of the implanted β-TCP or allograft was higher in younger patients than those in the older ones.Degradation of β-TCP was significantly higher than that of allografts over 3 years after surgery(P=0.04).In the experimental group,β-TCP degradation was greater in the loose packing treatment than that in the dense packing treatment (P=0.03).Histological observation demonstrated that the process of new bone formation accompanied the degradation of β-TCP.Conclusion The interporous β-TCP could be an advantageous alternative to allografts for repair bone defects caused by bone cyst.The clinical application of β-TCP is safe and reliable,which shows better biodegradation and osteogenesis than allografts in long-term follow-up.

The study is to establish an HPLC method using fluorescence detector for the determination of doxazosin enantiomers and investigate their chiral inversion in vitro and in vivo. Ultron ES-OVM was taken as the chiral chromatographic column, and the column temperature was 30 degrees C. Isocratic elution using a mobile phase of phosphate buffer-acetonitrile (85 : 15, v/v) at a flow rate of 0.8 mL x min(-1) was done. The fluorescence detection was set at lambda(Ex) = 255 nm and lambda(Em) = 385 nm. Prazosin was used as the internal standard. (-) Doxazosin or (+) doxazosin added into rat plasma in vitro was determined after incubating in 37 degrees C water bath for 2, 5 and 10 days. (-) Doxazosin or (+) doxazosin was administered orally to the rats for one months. Plasma samples were taken at 8 h after the last administration. A good linear relationship was achieved when the concentration of doxazosin enantiomers was within the range of 4 - 2 000 ng x mL(-1). The average recovery for (-) doxazosin was 99.5% with RSD 3.6%, and for (+) doxazosin was 99.3% with RSD 4.3%. Chiral inversion was observed neither in vitro nor in vivo studies. The method is selective, accurate and reproducible, which is suitable for the detection of doxazosin enantiomers in rat plasma. The in vitro and in vivo studies indicate that chiral inversion occurs uneasily between (-) doxazosin and (+) doxazosin in the rat.

Objective To analyze the image and histological results of the combined use of allograft/extracorporeally frozen tumor-bearing bone and vascularized fibular flap for the reconstruction of bony defects following tumor resection,guiding clinical practice.Methods From March 2007 to June 2013,we enrolled 63 patients who had combinative biological reconstruction after bone tumor resection (11 in humerus,22 in femur,21 in tibia,4 in calcaneus).There were 36 male and 27 female in this series.The average age at time of operation was 20 years,ranging from 9 to 48 years.The follow-up ranged from 16 to 102 months with average of 48 months.We investigated the X-ray and CT images for all patients and histological findings of two patients.Patients were assessed functionally with the Musculoskeletal Tumor Society 93 score.Results Three patients with local soft tissue recurrence and one patient with infection underwent amputation.The survival of construct was 93.6％.Bone union achieved in all cases with the average MSTS score of 92.8％.Bone union ranged from 11 to 28 months in allograft group and 9 to 14 months in devitalized tumor bearing bone group.Significant difference of bone union time was found between two groups (Z=-3.638,P=0.000).Viability of the fibular grafts was verified in 58 of 63 patients (92％).Three types of images were observed in complex.Osteopenia and spongy change in fibula were found in 51 patients (81％) with stable fixation of the complex.Five complexes with failed blood supply of fibula and stable fixation revealed no density change of fibula,small amount of callous formation and relative delayed union.In seven complexes (11％) with unstable complex due to patients' incompliance,fibula reacted with dense hypertrophy and microfracture.Fusion of grafts with amount of callus was obviously observed.Union at allograft-host bone junctions occurred by residual host bone-derived external callus and fibular-derived internal callus that bridged the junction and filled the gap between abutting cortices.Callus from fibular graft was mature than that from periosteum of residual host bone.Internal repair was observed at the internal surface of the allografts.Fibula showed significant spongy changes.Conclusion Recycled tumor-bearing bone in combined with fibular flap is a reliable reconstruction as an alternative to traditional Capanna technique.The survival of the fibula is a cornerstone in success of complex reconstruction.Sponginess of fibula and internal repair of allograft compromise the intensity of complex,necessitating the strong instrumentation during reconstruction.
