Comparison of the Outcomes between AO Type B2 Thoracolumbar Fracture with and without Disc Injury after Posterior Surgery.

Objective: The type AO B2 thoracolumbar fracture is a kind of flexion-distraction injury and the effect of disc injury on treatment results of patients with B2 fracture remains unclear. The objective of the current study was to compare and analyze the outcomes in AO Type B2 thoracolumbar fracture patients with and without disc injuries in terms of the Cobb angle of kyphosis, the incidence of complication, and the rate of implant failure.

Methods: This is a retrospective study.

Experiences in managing different consequences of forgotten ureteral stents.

Purpose: We reported the different consequences of forgotten stents and share our managing experiences.

Patients And Methods: From July 2011 to August 2019, eight patients (five men and three women) with forgotten encrusted ureteral stents were treated by different endoscopic procedures in our center. Plain-film radiography (kidney, ureter, and bladder [KUB]) and computed tomography were used to evaluate the position of stents, the site of encrustation, and the stone burden.

Enhancement of the bone-implant interface by applying a plasma-sprayed titanium coating on nanohydroxyapatite/polyamide66 implants in a rabbit model.

Solid fusion at the bone-implant interface (BII) is considered one of the indicators of a satisfactory clinical outcome for spine surgery. Although the mechanical and physical properties of nanohydroxyapatite/polyamide66 (n-HA/PA66) offers many advantages, the results of long-term follow-up for BIIs remain limited. This study aimed to improve the BII of n-HA/PA66 by applying plasma-sprayed titanium (PST) and assessing the mechanical and histological properties.

3D-printed titanium implant-coated polydopamine for repairing femoral condyle defects in rabbits.

Background: Large segmental bone defects are still one of the challenges for orthopaedic surgeons. Although 3D-printed porous titanium is a potential bone substitute material because of its porous structure simulating natural bone, the titanium surface has low bioactivity, integrates with bone tissue through the simple mechanical interlock. The study aims to investigate the capability and osteogenesis of 3D-printed porous titanium (3D PPT)-coated polydopamine (PDA) for repairing bone defects.

An approach to architecture 3D scaffold with interconnective microchannel networks inducing angiogenesis for tissue engineering.

The angiogenesis of 3D scaffold is one of the major current limitations in clinical practice tissue engineering. The new strategy of construction 3D scaffold with microchannel circulation network may improve angiogenesis. In this study, 3D poly(D: ,L: -lactic acid) scaffolds with controllable microchannel structures were fabricated using sacrificial sugar structures.

[Clinical and histological features of non-alcoholic fatty liver disease].

Objective: To investigate the clinical and histological features in Chinese patients with non-alcoholic fatty liver disease (NAFLD).

Methods: 108 patients with biopsy-proven NAFLD were enrolled in this study. Clinical, demographic, and biochemical data were compared between NAFLD patients with abnormal ALT and those with normal ALT.

[Hepatic steatosis: a common reason for elevated alanine aminotransferase levels in HBsAg-positive chronic hepatitis B patients with low HBV DNA loads].

Objective: To evaluate the causes of alanine aminotransferase (ALT) level elevation in HBsAg-positive chronic hepatitis B (CHB) patients with low HBV DNA loads.

Methods: One hundred nineteen HBsAg positive CHB patients with both serum HBV DNA loads less than 1000 copies/ml and ALT more than 1.25 upper limits of normal (ULN) lasting for at least 6 months were enrolled in this study.
