OBJECTIVES To investigate the relationship between H. pylori infection, gastric cancer and other gastric diseases through the changes in gastric mucosa and the status of different gastric diseases within 5 years after H. pylori eradication in H. pylori-positive subjects in a high incidence region of gastric cancer. METHODS One thousand and six adults were(More)
BACKGROUND We undertook this study in rats to investigate the role of hepatic sinusoidal endothelial cells (SECs) in hepatocyte proliferation early after partial hepatectomy and the regulatory mechanisms involved. METHODS The animal model of 70% hepatectomy was made. Hepatic SECs and hepatocytes were isolated and cultured according to the method of Braet(More)
Hydrogen sulfide (H(2)S) is an important signaling molecule produced from L-cysteine by cystathionine beta-synthetase (CBS) or cystathionine gamma-lyase (CSE). Here we examined the role of H(2)S in the oxygen-sensing function of the carotid body chemoreceptors, where the large conductance Ca(2+)-activated potassium channel (BK(Ca)) plays a key role. In the(More)
OBJECTIVE To evaluate the clinical manifestations, endoscopic, and radiological characteristics, histological features, and treatment of eosinophilic gastroenteritis in adult patients. METHODS The clinical records of 34 patients diagnosed as eosinophilic gastroenteritis and eight patients who had abdominal symptoms and unexplained peripheral eosinophilia(More)
The present paper attempted to develop temperature-sensitive and core-shell structured gel-nanocarriers (gel-NCs) for paclitaxel (PTX) with 12-hydroxystearic acid (12-HSA) as an organic gelator, which aims at sustaining drug release over time and thus improves the therapeutic effect. The gel-NCs were prepared by a mechanical mixing and high-pressure(More)
Oral drug delivery is the most preferred route for patients; however, the low solubility of drugs and the resultant poor absorption compromise the benefits of oral administration. On the other hand, for years, the overwhelmingly accepted mechanism for enhanced oral absorption using lipid nanocarriers was based on the process of lipid digestion and drug(More)
AIMS AND BACKGROUND To investigate the changing pattern of adenocarcinoma of the esophagogastric junction subtypes and its time trend relationship with that of reflux esophagitis over 10 years at a tertiary medical center in China. METHODS AND STUDY DESIGN . The medical records of all patients who underwent gastroscopy from 2000 to 2009 were reviewed.(More)
Spring scrub typhus has frequently occurred in Pingtan Island, China, since 2000. In this study, we amplified a 1352-bp DNA fragment encoding a truncated 56-kDa outer membrane protein of the Ptan strain, which was isolated from a serum sample of a patient with spring scrub typhus, and cloned it into the pET28a vector for expression. The expression product(More)
The marketed compound tablet of metformin hydrochloride (MH) and repaglinide (RG) exhibits perfect multidrug therapeutic effect of type 2 diabetes. However, due to the short half life of the drugs, the tablet has to be administered 2 to 3 times a day, causing inconvenience to patient and fluctuations of plasma concentration. Here, a sandwiched osmotic pump(More)
OBJECTIVE Collagenous gastritis is a rare entity, characterized by the deposition of a subepithelial collagen band with an inflammatory infiltrate in the mucosa. This report describes the first case of collagenous gastritis occurring in a young Chinese woman and reviews the literatures. METHODS The patient underwent the gastroscopy screening, and the(More)
