The objective of this study was to develop a novel, patient-specific, navigational template for thoracic pedicle screw placement. Twenty thoracic cadaver specimens were randomly divided into two groups of 10: the navigational template group and the free-hand group. A volumetric CT scan was performed on each thoracic vertebra, and a three-dimensional(More)
The objective of this study was to design a novel artificial bone scaffold for the therapy and prevention of refractory bacterial infections. Porous nano-hydroxyapatite/chitosan/konjac glucomannan (n-HA/CS/KGM) scaffolds were loaded with cationic liposomal vancomycin (CLV) to form a novel complex drug carrier (LLS). The kinetics of CLV release from LLS and(More)
Metastasis is a crucial hallmark of cancer progression, which involves numerous factors including the degradation of the extracellular matrix (ECM), the epithelial-to-mesenchymal transition (EMT), tumor angiogenesis, the development of an inflammatory tumor microenvironment, and defects in programmed cell death. Programmed cell death, such as apoptosis,(More)
The molecular mechanism underlying metastasis of chondrosarcoma (CS) remains unclarified. Here, we show that matrix metalloproteinase-26 (MMP26) level is significantly higher in the resected CS than in the adjacent healthy chondral tissue from the patients. To examine the role of MMP26 in CS invasion, we used a human CS line SW1353 and we either(More)
BACKGROUND The efficacy of sorafenib in the treatment of advanced hepatocellular carcinoma (HCC) remains controversial. Therefore, we conducted a meta-analysis to evaluate the efficacy and safety of sorafenib for treating patients with advanced HCC. METHODS The PubMed, Embase, and Web of Science databases were searched. Eligible studies were randomized(More)
The objective of this study was to design a novel artificial bone scaffold for therapy and prevention of refractory bacterial infection. Porous beta-tricalcium phosphate (beta-TCP) scaffold was combined with liposomal gentamicin (GS) to form a novel complex drug carrier. The liposome combined beta-TCP scaffold (LCS) was characterized for its liposome(More)
OBJECTIVE To develop a novel method of spinal pedical stereotaxy by reverse engineering and rapid prototyping techniques, and to validate its accuracy by experimental and clinical studies. METHODS A 3D reconstruction model for the desired lumbar vertebra was generated by using the Mimics 10.11 software, and the optimal screw size and orientation were(More)
Previous studies have shown that some microRNAs (miRs) are intensively involved in the development of hepatocellular carcinoma. We analyzed the prognostic role of serum microRNA (miR-122) levels in hepatocellular carcinoma patients using a retrospective design. MiR-122 levels in 122 hepatocellular carcinoma patients were measured, and Cox regression(More)
OBJECTIVE To study the anatomy of veins of the lower lumbar spine and provide the anatomic basement for laparoscopic lumbar surgery. METHODS A total of 15 formaldehyde-preserved cadavers were studied with special attention to the variety and surrounding structure of ascending lumbar vein (ALV) and iliolumbar veins (ILV), and their relationship with lumbar(More)
MicroRNAs (miRNAs) are endogenous 22 nt non-coding RNAs that target mRNAs for cleavage or translational repression. Numerous miRNAs regulate programmed cell death including apoptosis, autophagy and necroptosis. We summarize how miRNAs regulate apoptotic, autophagic and necroptotic pathways and cancer progression. We also discuss how miRNAs link different(More)
