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 inquire into the testis gene change of mouse model with kidney-yang deficiency induced by overfatigue and excessive sexual life, the modern science mechanism of syndrome of kidney-yang deficiency and kidney controlling reproduction can be revealed on the gene level. Methods: The model of kidney-yang deficiency was established by each male mouse with six female mice keeping in the same cage, and all the male mice were forced to swim for 30-40 minutes everyday lasting for four weeks. The testis genes of mice in control group and model group were detected with Mouse OneArrayTM Whole Genome DNA microarray. The differentially expressed genes were screened under the condition of the relative fluorescence intensity ratio of the two groups ≥2 and ≤0.5 and further classified according to gene function by using Molecule Annotation System (MAS) created by CapitalBio Corp. Beijing, China. Results: The mouse model with kidney-yang deficiency was established successfully by the method of overfatigue and excessive sexual life. The scatter plot of gene expression profiles of comparing control group with model group was drawn. Differentially expressed genes were screened, including 2425 up-regulated genes and 3080 down-regulated genes. Among the first one hundred up-regulated genes, 41 genes were known and among the first one hundred down-regulated genes, 62 genes were known. These genes were mainly related to the cellular structure/function, material/energy metabolism, signal transduction/transmission, inflammation/immunization, cell apoptosis, transcription/translation,proliferation/differentiation and cell cycle. Conclusion: The testis gene of kidney-yang deficiency mouse had a wide change. The essence of kidney-yang deficiency syndrome and the theory of the kidney originating and controlling life reproduction were explained on the gene level.

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.
