Magnetic Resonance Imaging-CCCFLS Scoring System: Toward Predicting Clinical Symptoms and C5 Paralysis.

Study Design: A retrospective study.

Objective: To develop a new MRI scoring system to assess patients' clinical characteristics, outcomes and complications.

Methods: A retrospective 1-year follow-up study of 366 patients with cervical spondylosis from 2017 to 2021.

Synthesis and carbothermal nitridation mechanism of ultra-long single crystal α-SiN nanobelts.

One-dimensional SiN nanostructures are desirable for constructing nanoscale electric and optoelectronic devices due to their peculiar morphologies. Herein, a facile and environmentally friendly catalyst-free method is proposed to synthesize ultra-long single crystal α-SiN nanobelts via carbothermal nitridation of carbon nanotubes at 1750 °C. The obtained α-SiN nanobelts with a flat surface (thickness of ∼150 nm, length of several millimeters) exhibited an extremely high aspect ratio, perfect crystal structure, and high specific surface area of 7.

Development of an Immunoassay for Chloramphenicol Based on the Preparation of a Specific Single-Chain Variable Fragment Antibody.

Specific antibodies are essential for the immune detection of small molecule contaminants. In the present study, the heavy and light variable regions (V(H )and V(L)) of the immunoglobulin genes from a hybridoma secreting a chloramphenicol (CAP)-specific monoclonal antibody (mAb) were cloned and sequenced. In addition, the light and heavy chains obtained from the monoclonal antibody were separated using SDS-PAGE and analyzed using Orbitrap mass spectrometry.

Surgical treatment of popliteal cyst: a systematic review and meta-analysis.

Background: This systematic review and meta-analysis of the clinical efficacy of different surgical methods in the therapy of popliteal cysts may provide evidence about effective surgical treatments.

Methods: PubMed, EMBASE, and OVID were searched with the following terms: (popliteal cyst* OR baker's cyst*) AND (arthroscopic OR excision OR operative OR treat* OR surgery). Inclusion criteria included the following: studies reported the efficacy of different surgical methods in popliteal cyst patients; patients were ≥ 16 years; and studies must have involved a minimum of 10 patients.

[Treatment of enophthalmos after severe malar-maxillary complex fracture with titanium mesh and high density polyethylene (Medpor)].

Objective: To study the surgical management of enophthalmos after severe malar maxillary complex fracture.

Methods: The X-ray and CT examination were performed before operation to diagnose the orbital fracture and intraorbital tissue displacement. The fractured orbital rim was repositioned intraoperatively, followed by implantation of shaped titanium mesh to rebuild the orbital floor.

[Clinical research of angle-splitting ostectomy based on three dimensional computed tomography true-up technique].

Objective: To illustrate the morphological changes of mandible after angle-splitting ostectomy.

Methods: From January 2006 to April 2008, 10 cases had undergone mandibular angle-splitting ostectomy to reduce the width of the lower face. For each patient, CT datum of mandible at three stages (preoperative, immediate postoperative, 6 months postoperative) were collected.

[Experimental study about osteotomy of mandibular outer cortex].

Objective: To investigate the change of morphology, biomechanics and histology after osteotomy of mandibular outer cortex.

Methods: The mandibular outer cortex that involves angle and part of body was removed at one side in 8 minitype pigs aged 8-12 months. 2 pigs were selected randomly for histologic examination 12 weeks after operation.

[Clinical research of craniofacial bone autograft using mandibular outer cortex].

Objective: To illustrate the volume changes of mandibular outer cortex after been grafted to different recipient sites of facies cranii.

Methods: Six cases underwent onlay bone graft to the angle and body part of mandible and malar surface simultaneously by using mandibular outer cortex. Three dimensional computed tomography (3D-CT) datum of immediate postoperative and 6 months postoperative of each case were collected systematically.

[Comparative study of onlay bone graft absorption of outer cortex from mandible and cranium].

Objective: To investigate the value of application of mandibular outer cortex as bone graft by comparing its bone absorption with cranial outer cortex.

Methods: 8 minitype grown-up pigs at the age of 8 - 12 months underwent surgery of taking out the same size (2.5 cm x 1.
