Patient-Derived Organoid Facilitating Personalized Medicine in Gastrointestinal Stromal Tumor With Liver Metastasis: A Case Report.

The gastrointestinal stromal tumors (GIST) are a rare gastrointestinal tract malignancy. The two primary mutation sites are found in KIT and platelet-derived growth factor receptor-α (PDGFR-α) genes. The current study reports on a point mutation within the exon 11 of KIT, named KIT p.

Quantitative analysis of morphometric parameters of fascicular groups of peripheral nerve on MicroCT images.

Background: Sectional image of the peripheral nerves is a prerequisite for studying the morphological parameters of fascicular groups. Ultra-high precision MicroCT scan can explicitly display the internal morphology of physiological tissues. This study aimed to quantitatively measure the basic morphological parameters of fascicular groups of a peripheral nerve on MicroCT images, obtain the statistical principles and investigate the variation pattern of these morphological parameters during the process of fascicular group extension.

Predictors for Submucosal Fibrosis in Patients With Superficial Squamous Esophageal Neoplasia Undergoing Endoscopic Submucosal Dissection.

Introduction: Submucosal fibrosis greatly hinders the success of endoscopic submucosal dissection (ESD). This study determined ESD outcomes in patients with esophageal submucosal fibrosis and further explored the predictors.

Methods: We retrospectively analyzed 163 patients with superficial squamous esophageal neoplasia.

Photodynamic therapy in combination with ranibizumab versus ranibizumab monotherapy for wet age-related macular degeneration: A systematic review and meta-analysis.

Objective: To evaluate the efficacy and safety between photodynamic therapy (PDT) combined with intravitreal ranibizumab (IVR) and ranibizumab monotherapy in treating wet age-related macular degeneration (AMD).

Methods: A systematic search was performed in the PubMed, Embase, Web of Science and the Cochrane Library databases through December 31, 2017. The methodological quality of the references was evaluated according to the Cochrane quality assessment.

[NR2B-pERK1/2-pElk-1 signaling contributes to the avoidance learning and memory of rats].

Aim: To investigate whether NR2B-pERK1/2-pElk-1 signaling contributes to the Y-maze learning and memory of rat brain.

Methods: 45 adult male SD rats were divided into 4 groups: (1) Ifenprodil peritoneal injection group (Ifenprodil ip, n = 14); (2) DMSO peritoneal injection group(DMSO ip, n = 15); (3) Ifenprodil cerebral ventricle injection group (Ifenprodil ic, n = 8); (4) DMSO cerebral ventricle injection group(DMSO ic, n = 8). Y-maze training and test were used as an learning and memory enhancing stimulus.
