Bilateral Endoscopic Debridement Combined with Local Antituberculosis Drugs for Thoracic Tuberculosis with Large Paravertebral Abscess: A Multicenter Study with 4-year Follow-Up.

Background: Paravertebral abscess represents a prevalent manifestation of thoracic tuberculosis, often necessitating surgical intervention. In this study, we introduced a novel approach by employing bilateral endoscopic debridement (BED) to address large Paravertebral abscesses associated with thoracic tuberculosis, a method not previously proposed in the literature. The clinical efficacy was examined through a comprehensive 4-year follow-up.

Bisphosphine-Stabilized Gold Nanoclusters with the Crown/Birdcage-Shaped Au Cores: Structures and Optical Properties.

To estimate the effect of bisphosphine ligands on the formation of the isomeric core structures of gold nanoclusters, the different ligation of bisphosphine ligands is usually used to participate in the construction of gold nanoclusters. Here, the selection of the different bisphosphine ligands, DPEphos and Xantphos, is performed to construct two novel gold nanoclusters, [Au(DPEphos)Cl]Cl () and [Au(Xantphos)Cl]Cl(), which have been characterized by IR, H and P NMR, ESI-MS, XRD, SEM, XPS, TG, UV-vis, and X-ray crystal structure analysis. The structural analyses indicate that the ligation of bisphosphine ligands play a crucial role in the formation of the fascinating Au cores: gold nanocluster includes a birdcage-shaped Au core with eight electrons, while gold nanocluster contains a crown-shaped Au core with eight electrons.

Bazedoxifene effects on osteoprotegerin, insulin-like growth factor, tumor necrosis factor and bone mineral density.

Unlabelled: To observe the clinical effect of estrogenic drugs (Bazedoxifene) on bone targeting in the treatment of osteoporosis and explore its mechanism.

Methods: 112 patients with postmenopausal osteoporosis who received Bazedoxifene drugs in our hospital from January to December 2018 were collected as a study group, and 56 patients treated with calcium alone were collected as a control group. the risk of adverse events such as bone mineral density, osteoprotegerin (OPG), insulin-like growth factor (IGF), tumor necrosis factor (TNF-α), and fracture after treatment were analyzed before and after treatment.

Accuracy Assessment of Using Rapid Prototyping Drill Templates for Atlantoaxial Screw Placement: A Cadaver Study.

To preliminarily evaluate the feasibility and accuracy of using rapid prototyping drill templates (RPDTs) for C1 lateral mass screw (C1-LMS) and C2 pedicle screw (C2-PS) placement. 23 formalin-fixed craniocervical cadaver specimens were randomly divided into two groups. In the conventional method group, intraoperative fluoroscopy was used to assist the screw placement.
