Novel sternoclavicular hook plate for the treatment of posterior sternoclavicular dislocation: a retrospective study.

Background: Controversies regarding the optimal internal fixation method for posterior sternoclavicular dislocation (SCD) exist. Therefore, this study aimed to investigate the clinical efficacy of a new type of sternoclavicular hook plate for treating posterior SCD.

Methods: Eleven patients (eight men and three women) with posterior SCD who underwent treatment with the new sternoclavicular hook plate from June 2011 to January 2022 were retrospectively analyzed.

Creation and Generation Mechanism of Macromolecular Representation for Dongsheng Coal Vitrinite.

Insights into macromolecules of coal were critical for improving the understanding of the coal upgrading and coalification process. Here, the creation and generation of macromolecular representation for Dongsheng coal vitrinite was clarified using industry analysis, elemental analysis, and the peak fitting technology of C nuclear magnetic resonance (C NMR), Fourier transform infrared spectrum, and X-ray diffraction. The structural parameters and macromolecular representation (CHNO) were innovatively calculated and created based on these characterization results and chemical shift correction, finally obtaining the plane macromolecular models whose C NMR spectrum was close to the experimental spectrum.

Obturator Oblique and Pubic Ramus Inlet Views Can Better Guide the Insertion of an Anterior Column Acetabular Screw.

Objective: The objective of the present paper was to investigate the value of obturator oblique and pubic ramus inlet views in guiding anterior column acetabular screw insertion.

Methods: We collected pelvic CT scans at the diagnostic imaging center of our hospital between 2017 and 2019. Virtual three-dimensional (3D) models of the pelvis were created based on the CT scans.

The influence of timing of surgery in the outcome of spinal cord injury without radiographic abnormality (SCIWORA).

Background: Spinal cord injury without radiographic abnormality (SCIWORA) is a rare traumatic myelopathy. Although surgery is one of the most important treatments, the surgery for SCIWORA is controversial, especially the time of surgery is a topic of controversy. Here, we investigate the effects of difference in duration from injury to surgery on the outcome of SCIWORA.

[Research on optimization system on tissue culture and rapid propagation of Pueraria mirifica].

Objective: To study the tissue culture and rapid-proliferation techniques of Pueraria mirifica.

Method: The tender branch were used as explants and cultivated in different media. The optimum media for inducing buds, proliferation and rooting were selected by adjusting the kinds and doses of plant hormones and special compounds.
