Open-door laminoplasty is a commonly performed procedure for the treatment of multiple level cervical spinal stenosis. One complication of this procedure is closure of the hinge and subsequent restenosis. Twinfix suture anchor was used in laminoplasty to stabilize cervical canal expansion. 53 patients with multiple level cervical spinal stenosis underwent(More)
Process industries are important component of Chinese economy. While supply chain risks are going up rapidly under globalization, it affects process industries to operate continuously and safely. Thus it is necessary to research on how to manage risks in process industries supply chain effectively. In this paper, we identify supply chain risks underlying(More)
OBJECTIVES This study aimed to investigate the outcomes after using a combination of anterior-posterior approaches to treat ankylosing spondylitis (AS) complicated by a multiple-level cervical vertebral Chance fracture. METHODS We retrospectively analyzed 11 patients with AS complicated by a multiple-level cervical vertebral Chance fracture. RESULTS(More)
OBJECTIVE To explore the role of toll-like receptor 2 (TLR2) and toll-like receptor 4 (TLR4) in myocardial ischemia/reperfusion injury (MI/RI) by observing the dynamic expression changes at mRNA and protein levels early after myocardial ischemia/reperfusion (I/ R). METHODS The Wistar rats were randomly divided into Sham and I/R group (n = 42), and killed(More)
Muscarinic acetylcholine receptor belongs to the G-coupled receptor family, the cooperation between its five subtypes is crucially important in maintaining the normal physiological function. At present, many types of biological resources are increasing, which provides unprecedented opportunities to study the relationships between muscarinic acetylcholine(More)
Chitosan (CS)-based hydroxyapatite (HA) composites have emerged as a novel strategy for promoting bone regeneration. Here nanophase HA/CS composite coated porous titanium implants (nCT) were fabricated and their biological behavior under diabetic conditions was investigated. We proposed that the focal adhesion kinase (FAK)-mediated BMP-2/Smad pathway played(More)
AIM To investigate the stress-induced apoptosis of natural killer (NK) cells and the changes in their killing activity in mouse livers. METHODS A restraint stress model was established in mice. Flow cytometry was employed to measure the percentage of NK cells and the changes in their absolute number in mouse liver. The cytotoxicity of hepatic and splenic(More)
OBJECTIVE To choose a proper method of lumbar transpedicular screw fixation at different lumbar levels among the three methods (Roy-Camille's method, Magerl's method and Du's method) in the Chinese population. METHODS Three-dimensional (3-D) images were reconstructed with image data of 42 adult lumbar segments that were scanned by Electron Beam CT. The(More)
Assessing the biomechanical properties of trabecular bone is of major biological and clinical significance for the research of bone diseases, fractures and their treatments. Micro-finite element (µFE) models are becoming increasingly popular for investigating the biomechanical properties of trabecular bone. The shapes of µFE models typically include cube(More)
OBJECTIVE To elucidate whether ZFP580 is involved in the cardioprotective effects of intermittent hypobaric hypoxia (IHH) against myocardial ischemia/reperfusion (I/R) injury. METHODS Thirty two male Wistar rats were randomly divided into 2 groups (n = 16): normoxia control group and IHH preconditioning group. Rats in IHH group were exposed in a hypobaric(More)
