Development and Validation of a Preoperative Prediction Model for Neoplastic Gallbladder Polyps.

The primary goal in evaluating gallbladder polypoid lesions (GPLs) is to identify neoplastic polyps (NP). Numerous studies have investigated risk factors for NP. This study aimed to develop a practical preoperative prediction model for NP using simple and easily accessible clinical variables.

Hemorrhagic Shock Caused by Spontaneous Bleeding from Early Gastric Cancer Was Successfully Cured by Emergency Endoscopic Submucosal Dissection: A Case Report.

Cases and studies of protruding early gastric cancer (EGC) combined with spontaneous bleeding are relatively rare. The current study present a female patient aged 70 to 75 years old with hemorrhagic shock caused by spontaneous bleeding from EGC type 0-Isp, which was successfully cured by rapid emergency endoscopic submucosal dissection (ESD).

[Progress of research on the relationship between calcitonin gene-related peptide and RANK/RANKL/OPG system in the bone reconstruction].

Objective: To summarize the research progress on the calcitonin gene-related peptide (CGRP) and receptor activator of nuclear factor κB (RANK)/receptor activator of nuclear factor κB ligand (RANKL)/osteoprotegerin (OPG) system during bone reconstruction to provide theoretical basis for further research on the prevention and treatment of bone-related diseases.

Methods: The relevant research results at home and abroad in recent years were analyzed and summarized.

Results: CGRP and RANK/RANKL/OPG system play important regulatory roles in the bone reconstruction.

[Research progress of lateral wall injury of intertrochanteric fracture].

Objective: To summarize the general concept of lateral wall, the causes of lateral wall injury, and surgical strategies in order to improve the understanding of lateral wall and reduce the complications of operation.

Methods: The related literature on lateral wall was extensively reviewed, summarized, and analyzed.

Results: The superior extent of the lateral wall is vastus lateralis ridge and the inferior extent is the intersection between the lateral femoral cortex and a line drawn at a tangent to the inferior femoral neck.
