Percutaneous short segmental fixation combined with bone cement augmentation for stage III Kümmell's disease without nerve deformity.

The objective of this study was to evaluate the safety and efficacy of percutaneous pedicle screw fixation combined with bone cement augmentation in the management of stage III Kümmell disease without nerve deformity. A retrospective analysis was conducted on 17 patients diagnosed with stage III Kümmell disease without nerve deformity, who underwent treatment with percutaneous pedicle screw fixation combined with bone cement augmentation between April 2019 and 2022. Preoperative, postoperative, and final follow-up clinical outcome measures were collected, including Visual Analog Scale scores and Oswestry Disability Index scores.

Generation and characterization of a monoclonal antibody against FGFR3 that protects mice from BoNT/A.

Botulinum neurotoxin serotype A (BoNT/A) can cause flaccid paralysis of muscles, an illness fatal to human, by entering neurons and blocking neurotransmitter release. The process was mediated by three receptors. A specific monoclonal antibody anti-D23, designated as ML419, targeting the ectodomain (D23) of fibroblast growth factor receptor 3 (FGFR3), one of the three receptors, was screened and capable of disturbing the recognition of BoNT/A and FGFR3.

[Clinical and radiologic comparison between oblique lateral interbody fusion and minimally invasive transforaminal lumbar interbody fusion for degenerative lumbar spondylolisthesis].

Objective: To compare the short-term clinical efficacy and radiologic differences between oblique lateral interbody fusion(OLIF) and minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) for degenerative lumbar spondylolisthesis.

Methods: A retrospective analysis was performed on 58 patients with lumbar spondylolisthesis treated with OLIF or MIS-TLIF from April 2019 to October 2020. Among them, 28 patients were treated with OLIF (OLIF group), including 15 males and 13 females aged 47 to 84 years old with an average age of (63.

The analgesic efficacy of extracorporeal shock wave combined with percutaneous vertebroplasty in the treatment of osteoporotic thoracolumbar compression fractures in postmenopausal women.

Background: To explore the analgesic efficacy of extracorporeal shock wave (ESW) combined with percutaneous vertebroplasty (PVP) after reduction in overextension position in the treatment of osteoporotic thoracolumbar compression fractures in postmenopausal women.

Methods: The data of postmenopausal women with osteoporotic thoracolumbar compression fracture admitted in our department from January 2017 to October 2019 were analyzed retrospectively. They were divided into groups of unipedicular percutaneous kyphoplasty (U-PKP n = 21), bipedicular PKP (B-PKP n = 20), and ESW combined with PVP after reduction in overextension position (EP-PVP n = 18).

Structural basis of valmerins as dual inhibitors of GSK3β/CDK5.

Development of multi-target drugs is becoming increasingly attractive in the repertoire of protein kinase inhibitors discovery. In this study, we carried out molecular docking, molecular dynamics simulations, molecular mechanics Poisson-Boltzmann surface area (MM-PBSA) binding free energy calculations, principal component analysis (PCA), and dynamical cross-correlation matrices (DCCM) to dissect the molecular mechanism for the valmerin-19 acting as a dual inhibitor for glycogen synthase kinase 3β (GSK3β) and cyclin-dependent kinase 5 (CDK5). Detailed MM-PBSA calculations revealed that the binding free energies of the valmerin-19 to GSK3β/CDK5 were calculated to be -12.

[The study for the hemodynamics of expansive skin and the transplant time of skin flap designed by expansive skin].

Objective: To study the change rule of the hemodynamics of expanded skins and research the transplant time of random-pattern flaps that are made of the expanded skin.

Methods: 72 ears of 64 rabbits were used as a subject of experiment. Four items of the contrasted skin (n = 8) and expanded skin (n = 8 x 8), Which include the microvessel diameter, the microvessel density, the blood velocity and the blood volume, were observed and measured by the microcirculatory imaging computer analysis system, the enzyme histochemical dyeing and the more functions colored pathological imaging computer analysis system.
