Endoscopic papillectomy for synchronous adenoma of the major and minor duodenal papilla.

Objectives: Synchronous adenomas of the major and minor duodenal papilla are seldom reported. The aim of this study was to describe the characteristics of synchronous major and minor papilla adenomas and to evaluate the safety and efficacy of endoscopic papillectomy (EP) for the management of the disease.

Methods: Consecutive patients who underwent endoscopy for synchronous major and minor papilla adenomas from January 1, 2013 to August 31, 2023 were analyzed retrospectively.

Rare squamous cell carcinoma of the jejunum causing perforated peritonitis: A case report.

Background: Adenocarcinoma has the highest incidence among malignant tumors of the small intestine (SI). Squamous cell carcinoma (SCC) often occurs in organs covered with squamous epithelium. Primary or metastatic SCC originating from the SI is very rare, with very few cases reported in the literature.

Esophageal superficial adenosquamous carcinoma resected by endoscopic submucosal dissection: A rare case report.

Background: Adenosquamous carcinoma (ASC), which is comprised of squamous cell carcinoma (SCC) and adenocarcinoma elements, is a rare histological type of esophageal carcinoma. Few reports have focused on the endoscopic findings and the effectiveness of the endoscopic treatment of early ASC.

Case Summary: A 77-year-old man underwent esophagogastroduodenoscopy for heartburn.

[Simulation for balanced effect of soil and water resources on cultivated land in Naoli River Basin, Northeast China under the RCPs climate scene].

Under the scenarios of climate change, balancing the land and water resources is one of the key problems needed to be solved in land development. To reveal the water dynamics of the cultivated land in Naoli River Basin, we simulated the future scenarios by using the future land use simulation model based on Landsat Satellite images, the DEM data and the meteorological data. Results showed that the growth rate of cultivated land gradually decreased.

[Clinicopathological screening of Lynch syndrome: a report of 2 cases and literature review].

Lynch syndrome is an autosomal dominant genetic disease characterized by the early onset of colon cancer, endometrial cancer and other tumors caused by a genetic mutation within DNA mismatch repair (MMR) genes. A small subgroup (approximately 3%-5%) of endometrial cancer and colorectal cancer is related to Lynch syndrome. Identification of these patients in clinical practice will be of great benefit to the relatives and patients themselves.

[Effects of intermittent hypoxic exposure on the parameter of erythrocyte and serum hypoxia inducible factor-1 alpha and erythropoietin levels].

Aim: To investigate the effects of intermittent hypoxic exposure and normoxic convalescence on the parameter of erythrocyte and serum hypoxia inducible factor-1 alpha (HIF-1alpha) and erythropoietin (EPO) levels.

Methods: Rat models of intermittent hypoxic exposure were established, combined with the clinical research on volunteers experiencing the intermittent plateau work. Blood samples for red blood cell (RBC) counts, hemoglobin (Hb) and hematocrit (HCT) were collected, serum HIF-1alpha and EPO levels were measured using enzyme linked immunosorbent assay.
