Penetrating neck trauma caused by a rebar: A case report.

Rationale: Penetrating neck trauma has a mortality of 3% to 6% and is associated with serious complications, mainly due to the high density of vital structures in this area and the lack of corresponding protection from bone.

Patient Concerns: A 55-year-old man who suffered neck trauma involving the parotid gland, caused by a rebar, after suffering a fall from the second floor of a building.

Diagnoses: Penetrating neck trauma.

Facile microencapsulation of olive oil in porous starch granules: Fabrication, characterization, and oxidative stability.

In this study, starch with porous structures derived from purple sweet potato was prepared and used as a food-grade polymer for the microencapsulation of olive oil. The optimal reaction conditions for preparing porous starch were determined to improve its adsorption capacity as effective microcapsule-wall materials. Olive oil was then impregnated in microspheres, and loading ratio was optimized by investigating the restrictive factors, including the mass ratio of olive oil to porous starch, as well as the embedding temperature and time.

Effect of Kruppel-like factor 4 on Notch pathway in hepatic stellate cells.

The relationship between Kruppel-like factor 4 (KLF4) and the Notch pathway was determined to investigate the effect of KLF4 on the activation of hepatic stellate cells and underlying mechanisms. Fifty SPF BALB/c mice were randomly divided into two groups. A liver fibrosis model was established in 25 mice as the experimental group, and the remaining 25 mice served as controls.

Trans-superior meatus endoscopic surgery of sphenoidal sinus and sellar area: a surgical technique for lesion of sellar area.

Conclusion: A trans-superior meatus endoscopic approach to treat diseases in the sphenoid sinus and sellar area is a safe, minimally traumatic, and effective method.

Objective: To avoid complications, we explored the use of the superior meatus and superior turbinate in the endoscope approach to the sphenoid sinus and sellar area.

Patients And Methods: This was a retrospective analysis of the curative effect of the trans-superior meatus approach for diseases in the sphenoid sinus and sellar area in 138 cases.

[The diagnosis and treatment of special airway foreign body].

Objective: The aim of this study was to discuss the diagnosis and treatment of special airway foreign body.

Method: Clinical data of 69 patients with airway foreign body were analyzed,of which 45 patients underwent rigid bronchoscopy while another 24 patients underwent tracheotomy.

Result: The operations succeeded in 43 of the 45 patients who underwent rigid bronchoscopy, while the other 2 patients died of respiratory failure because of the foreign body slipping off at the level of the glottis.

[Image examination of postoperative evaluation for the cochlear implanted electrode].

Objective: To evaluate the image feature of the X-ray plain film, the spiral computed tomography (CT) scans and three dimension reconstruction of inner ear with implanted electrode.

Methods: Eighteen patients of cochlear implant (MEDEL Combi 40+) recipients were involved in this study. The implanted electrode of all patients were examined on the fifth to seventh postoperative day, by the use of X-ray plain film with either anteroposterior transorbital projection (nine cases) or lateral position with coronal 60 degrees away from the examine table (nine cases).

[Integrated methods for assessing auditory nerve-auditory pathway integrity].

Objective: To evaluate the feasibility and value of integrated methods to assess auditory pathway integrity.

Method: Twenty-four cases of bilateral profoundly-deafened individuals who were considered as the candidates of cochlear implantation were included in this study. Auditory pathway integrity from these candidates of cochlear implantation were assessed with the integrated methods established by our team, which consist of 5 categories including 1.
