[A preliminary study on the surgical timing of spinal tuberculosis].

Objective: To observe the changes of erythrocyte sedimentation rate (ESR), C-reactive protein (CRP) and nerve function in patients with spinal tuberculosis before and after surgery, explore the timing of surgical intervention, and evaluate its influence on surgical safety.

Methods: A retrospective analysis was conducted on 387 patients with spinal tuberculosis who received surgical treatment from March 2012 to March 2017, including 278 males and 109 females, aged 12 to 86 years old with an average of (49.9±19.

[Comparative analysis of binding multi-fold rib graft, iliac bone graft and titanium mesh graft during surgery of tuberculosis of thoracic vertebra].

Objective: To compare the clinical effects of three different methods of binding multi-fold rib graft, iliac bone graft and titanium mesh graft in tuberculosis of thoracic vertebra by approach of transverse rib process.

Methods: A hundred and seven patients with tuberculosis of thoracic vertebra received surgical treatment from January 2010 to December 2016 were retrospectively analyzed. The patients were divided into three groups according different methods of bone graft.

[Application of cortical bone trajectory screw in elderly patients with lumbar tuberculosis].

Objective: To explore the clinical effect of cortical bone trajectory screw technology combined with anterior mini-open debridement and prop graft for lumbar tuberculosis in elderly.

Methods: The clinical data of 22 patients with lumbar tuberculosis treated by cortical bone trajectory screw technology combined with anterior mini-open debridement and prop graft from February 2015 to December 2016 were retrospectively analyzed. There were 13 males and 9 females with an average age of (73.

[Eearly clinical effects of percutaneous endoscopic focal cleaning and drainage in the treatment of single-level suppurative spondylitis].

Objective: To evaluate the clinical value of percutaneous endoscopic focal cleaning and drainage in the treatment of single-level suppurative spondylitis.

Methods: The clinical data of 18 patients with single-level suppurative spondylitis treated by percutaneous endoscopic focal cleaning and drainage from June 2014 to December 2015 were retrospectively analyzed. There were 11 males and 7 females, aged from 46 to 75 years old with an average of (58.

[Application value of Xpert MTB/RIF in diagnosis of spinal tuberculosis and detection of rifampin resistance].

Objective: To investigate the application value of Xpert MTB/RIF in diagnosis of spinal tuberculosis and detection of rifampin resistance.

Methods: The 109 pus specimens were obtained from patients who were primaryly diagnosed as spinal tuberculosis. All of the pus specimens were detected by acid-fast stain, liquid fast culturing by BACTEC MGIT 960 and Xpert MTB/RIF assay to definite the differences in sensitivity and specificity of mycobacterium tuberculosis among detecting methods.

[Estimation of net primary productivity in arid region based on coupling model.].

Net primary productivity (NPP), as the base for the research of matter recycling and energy flow in terrestrial ecosystem, is sensitive to the changes of environment and climate in arid region, and also is an important indicator of eco-environmental characteristics. Based on remote sensing (RS) and geographic information system (GIS), using meteorological data, eddy cova-riance data, Landsat 8 and MODIS data, this study coupled SEBAL model and light utility efficiency model to estimate the NPP of vegetation in Manas River Watershed, and the spatial pattern of NPP and the relationships between NPP and terrain factors (elevation and slope) were analyzed. Results showed that the estimated result of NPP in Manas River Watershed by coupling model was reasonable and could actually reflect the NPP of vegetation.
