Pyloric gland adenoma with low-grade intraepithelial neoplasia: A case report and literature review.

Rationale: Pyloric gland adenoma (PGA) is often associated with pyloric gland metaplasia. It has high malignant potential but a low clinical diagnosis rate. Therefore, we reported a case of PGA and reviewed the literature to summarize the clinicopathological features of pyloric adenoma.

Cleansing efficacy and safety of bowel preparation protocol using sodium picosulfate/magnesium citrate considering subjective experiences: An observational study.

Background: Research data from patient reports indicate that the least bearable part of colonoscopy is the administration of laxatives for bowel preparation.

Aim: To observe the intestinal cleansing efficacy and safety of sodium picosulfate/magnesium citrate and to discuss the patients' experiences due to the procedure.

Methods: Subjects hospitalized in the International Medical Center Ward of Peking University International Hospital, Beijing, China, from April 29 to October 29, 2020, for whom the colonoscopy was planned, were enrolled.

Gastric adenocarcinoma of the fundic gland type: A case report.

Introduction: Gastric adenocarcinoma of the fundic gland type (GA-FG) is a newly described entity that is characterized by well-differentiated neoplasm with unclear etiopathogenesis.

Patient Concerns: A 60-year-old Chinese man was referred to our hospital for abdominal distension.

Diagnosis: Esophagogastroduodenoscopy (EGD) showed a depressed lesion found using in the greater curvature of the stomach.

Clinical significance and influencing factors of linked color imaging technique in real-time diagnosis of active Helicobacter pylori infection.

Background: Determining the Helicobacter pylori (H. pylori) infection state during the gastroscopic process is important but still challenging. The linked color imaging (LCI) technique might emphasize the mucosal color change after H.

A Retrospective Research of the Characteristic of Hypertriglyceridemic Pancreatitis in Beijing, China.

Aim. To investigate the characteristic of hypertriglyceridemic- (HTG-) induced pancreatitis (HTG pancreatitis). Methods.

Doxorubicin nanobubble for combining ultrasonography and targeted chemotherapy of rabbit with VX2 liver tumor.

A new class of multifunctional nanobubble using poly(lactic-co-glycolic acid) (PLGA) has been developed as ultrasound imaging contrast agents, doxorubicin carriers, and enhancers of ultrasound-mediated drug delivery. The doxorubicin nanobubble (DOX-NB) wrapping carbon tetrafluoride gas was prepared with double emulsion method. We evaluated the enhanced ultrasonic function of the DOX-NB in vivo; its antitumor function was confirmed.

Effectiveness of systematic training in the application of narrow-band imaging international colorectal endoscopic (NICE) classification for optical diagnosis of colorectal polyps: Experience from a single center in China.

Background And Aim: To evaluate the effectiveness of systematic training in the application of narrow-band imaging (NBI) International Colorectal Endoscopic (NICE) classification for the prediction of the histology of colorectal polyps.

Methods: This is a single-center study. In total, 260 still images of colorectal polyps from 225 patients were included.

The mechanisms of 5-FU-PLA-O-CMC-NPS-mediated inhibition of the proliferation of colorectal cancer cell line SW480.

We aimed to investigate how 5-FU-PLA-O-CMC-NP (5-FPOCN) inhibits the proliferation of the SW480 colon cancer cell line. Following the treatment of cell line SW480 with 0.1, 1, 10 or 100 μg/ml 5-FPOCN or 5-fluorouracil (fluorouracil, 5-Fu) for 0, 24, 48, or 72, the rate of cell was tested by the tetrazolium assay (MTT).

The inhibition of Wnt/β-catenin signaling pathway in human colon cancer cells by sulindac.

The aberrant activation of Wnt/β-catenin signaling plays important roles in the initial development of colon cancer. Sulindac is a commonly used non-steroidal anti-inflammatory drug. We demonstrated the effects of sulindac on growth inhibition, apoptosis induction, and Wnt/β-catenin signaling suppression in human colon cancer cells.

Peritoneal metastatic adenocarcinoma possibly due to a gastric duplication cyst: a case report and literature review.

Background: Gastric duplication cysts are rare congenital abnormalities, and malignant transformation of these duplications is also thought to be rare.

Case Presentation: During a routine health checkup, a 28-year-old man underwent abdominal sonography followed by computed tomography (CT) with contrast agent, which revealed a cystic lesion with no enhancement. Laparoscopic surgery showed a 10 × 10 cm cyst adhering to the gastric corpus.

Evaluating the diagnoses of gastric antral lesions using magnifying endoscopy with narrow-band imaging in a Chinese population.

Aim: To evaluate the accuracy of diagnosing gastric antral lesions in routine clinical practice using magnifying endoscopy with narrow-band imaging (M-NBI) as a real-time diagnosing technique.

Methods: Consecutive patients undergoing upper endoscopy were selected for the study. In each patient, the mucosa of the gastric antrum was observed by M-NBI, and the gastric microstructure was categorized into five types (A-E).

The clinical analysis of 34 cases of intestinal tuberculosis in China's big city hospitals.

Aims: Intestinal tuberculosis is not uncommon in developing countries. The diagnosis of this disease is quite difficult. The purpose of our research was to recall the clinical, colonoscopic, and histopathological features of this disease.

Six ulcerative colitis patients with refractory symptoms co-infective with Blastocystis hominis in China.

Blastocystis hominis is an enteric parasite which has long been considered as an innocuous commensal living in the intestinal tract. Our research was to explore the role of B. hominis in refractory ulcerative colitis.
