Ovarian-adnexal reporting and data system ultrasound evaluation and pathological characteristics of ovarian collision tumor.

Background: Collision tumor are neoplasms, including two histologically distinct tumors that coexist in the same mass without histological admixture. The incidence of collision tumor is low and is rare clinically.

Aim: To investigate ultrasound images and application of ovarian-adnexal reporting and data system (O-RADS) to evaluate the risk and pathological characteristics of ovarian collision tumor.

Clinical study on the use of advanced magnetic resonance imaging in lupus nephritis.

Objectives: To investigate the correlation between the histopathology of the kidney and clinical indicators in patients with lupus nephritis (LN) using magnetic resonance imaging (MRI).

Methods: A total 50 female participants were enrolled in the study. Thirty patients with LN were divided into types 2, 3, 4, and 5, according to their pathological features.

circPlekha7 suppresses renal fibrosis via targeting miR-493-3p/KLF4.

The authors aim to investigate the function of circPlekha7 in renal fibrosis. Human renal tissues from chronic kidney disease patients, kidney cell line and primary cultured renal tubular epithelial cells were used. TGF-β1-treated human kidney 2 cells/tubular epithelial cells and a unilateral ureteral obstruction mouse model were employed to study renal fibrosis.

[Phonation reconstruction and function assessment after total and near-total laryngectomy].

Background & Objective: Total laryngectomy is a common surgery pattern for treating laryngeal and hypopharyngeal cancer, but patients will lost phonation function after operation. This study was to retrospectively analyze usage of modified Amatsu, and modified Pearson operation in treating laryngeal and hypopharyngeal cancers, and to analyze phonation function by subjective and objective assessment.

Methods: Clinical data of 69 patients with laryngeal or hypopharyngeal cancer treated by total or near-total laryngectomy (modified Amatsu or modified Pearson operation) in our department from 1996 to 2003 were retrospectively analyzed.

[Surgical treatment of thyroid carcinoma with the upper mediastinal invasion].

Objective: To study the surgical management of the thyroid carcinoma with the upper mediastinal invasion.

Methods: Among the 560 thyroid carcinoma cases receiving surgery from 1988 to 1999, there were 10 cases of the upper mediastinal, the 10 cases were retrospectively analyzed for their preoperative diagnosis, surgical methods and postoperative complications.

Results: The upper mediastinal invasion rate of the 560 cases was 1.

[Surgical treatment of advanced thyroid carcinoma with aero-digestive invasion].

Objective: To study the surgical management of the advanced thyroid carcinoma with aero-digestive invasion.

Methods: To analyze 18 cases of advanced thyroid carcinoma which had aerodigestive invasion retrospectively, the patients were treated from 1988 to 1998.

Results: The rate of aerodigestive invasion occur was 3.

[Application of frontal-lateral laryngectomy in laryngeal cancer treatment].

Objective: Thirty-eight patients of laryngeal cancer were treated by extended frontal-lateral laryngectomy and the results were evaluated.

Methods: Thirty-eight patients with laryngeal cancer were treated by frontal-lateral laryngectomy and the laryngeal defects were reconstructed by epiglottic flap, bi-pedicle and bi-muscle flap and epiglottic flap plus bi-pedicle and bi-muscle flap from February 1988 to February 2000. There were 29 males and 9 females, ranging in age from 32 to 72 years old.
