Diagnosis model for gastric submucosal tumor based on multiple decision trees comprising endoscopic and endoscopic ultrasonography features.

Background: The clinical course and manifestations of subepithelial lesions (SEL) patients tend to vary from different pathological types, therefore the accurate diagnosis of SEL would undoubtedly be beneficial to the treatment and prognosis of SEL patients. Based on the decision tree method, we developed a novel classification model for SELs by combining endoscopy with endoscopic ultrasound (EUS).

Methods: We retrospectively collected data from 469 patients hospitalized in the Affiliated Hospital of Qingdao University between January 2017 to November 2021 for endoscopic resection.

Articular cartilage degradation is prevented by tanshinone IIA through inhibiting apoptosis and the expression of inflammatory cytokines.

The present study aimed to investigate the effect of tanshinone IIA on the degradation of articular cartilage in a rat model of osteoarthritis (OA). The OA rat model was established by anterior cruciate ligament transection (ACLT) and medial meniscus resection (MMx). The animals were treated for 28 days with 0.

A study on role of triiodothyronine (T3) hormone on the improvement of articular cartilage surface architecture.

The present study was aimed to investigate the effect of triiodothyronine (T3) on the improvement of articular cartilage surface architecture at in vitro level. The T3 hormone was applied to neo-tissues in the range of 50, 100, 150 and 200ng/ml for 5 weeks. At the end of the treatment, biochemical and histological evaluation was carried out in the neo-tissues.

Physcion, a naturally occurring anthraquinone derivative, induces apoptosis and autophagy in human nasopharyngeal carcinoma.

Aim: Physcion is a major bioactive ingredient in the traditional Chinese medicine Radix et Rhizoma Rhei, which has an anthraquinone chemical structure and exhibits a variety of pharmacological activities including laxative, hepatoprotective, anti-inflammatory, anti-microbial and anti-proliferative effects. In this study we investigated the effect of physcion on human nasopharyngeal carcinoma in vitro and in vivo, as well as the mechanisms underlying the anti-tumor action.

Methods: The nasopharyngeal carcinoma cell line CNE2 was treated with physcion, and cell viability was detected using MTT and colony formation assays.

The tumor-stroma ratio is an independent predictor for survival in nasopharyngeal cancer.

Background: The tumor-stroma ratio (TSR) has been identified as a new and practicable prognostic histological characteristic of solid tumors. The aim of this study was to evaluate the prognostic value of the TSR in nasopharyngeal cancer (NPC).

Patients And Methods: A total of 93 patients who presented with NPC from 2004 to 2007 were studied.

Treatment of osteonecrosis of femoral head with BMSCs-seeded bio-derived bone materials combined with rhBMP-2 in rabbits.

Objective: To evaluate the effect of autologous bone marrow mesenchymal stem cells (BMSCs) seeded bio-derived bone materials (BBM) combined with recombinant human bone morphogenetic protein-2 (rhBMP-2) in repairing defect of osteonecrosis of femoral head (ONFH).

Methods: Early-stage osteonecrosis in the left hip was induced in 36 adult New Zealand white rabbits (provided by the Animal Center of Guangxi Medical University, Nanning, China) after core decompression and delivery of liquid nitrogen into the femoral head. Then the animals were divided into three groups according to the type of implants for bone repair: 12 rabbits with nothing (Group I, the blank control group), 12 with BBM combined with rhBMP-2 (Group II), and 12 with BMSCs-seeded BBM combined with rhBMP-2 (Group III).
