Current status of severe acute respiratory syndrome in China.

Severe acute respiratory syndrome (SARS), also called infectious atypical pneumonia, is an emerging infectious disease caused by a novel variant of coronavirus (SARS-associated coronavirus, SARS-CoV). It is mainly characterized by pulmonary infection with a high infectivity and fatality. SARS is swept across almost all the continents of the globe, and has currently involved 33 countries and regions, including the mainland China, Hong Kong, Taiwan, North America and Europe.

[In-vitro activity of rabeprazole, lansoprazole, and esomeprazole against Helicobacter pylori].

Objective: To investigate the antimicrobial activity of Pariet, Tekpron, Nexium, respectively, against Helicobacter pylori (H. pylori) in vitro.

Methods: Antimicrobial effects of these medicines were evaluated through detection of MICs for 3 H.

[Primary analysis on protein maps of Helicobacter pylori strains associated with gastric carcinoma].

Objective: To identify specific proteins of Helicobacter pylori (H. pylori) that associated with gastric carcinoma.

Methods: The whole-cell proteins of H.

[A prospective randomized study on the method of reconstruction after total gastrectomy].

Objective: To find an ideal reconstruction method after total gastrectomy.

Methods: With 12 healthy persons as control, a total of 120 gastric cancer patients received their digestive tract reconstruction after total gastrectomy were randomized into Roux-en-y esophagojejunostomy group (A), P pouch with Roux-en-y esophagojejunostomy group (B), Hunt-Lawrence esophagojejunostomy group (C), and jejunal interposition esophagojejunostomy group (D). After operation, quality of life, prognosis nutrition index (PNI), body weight, serum nutritional parameters, gastrointestinal hormone level and immunological state were evaluated.

Severe acute respiratory syndrome and its lesions in digestive system.

Severe acute respiratory syndrome (SARS) is an infectious atypical pneumonia that has recently been recognized in the patients in 32 countries and regions. This brief review summarizes some of the initial etiologic findings, pathological description, and its lesions of digestive system caused by SARS virus. It is an attempt to draw gastroenterologists and hepatologists' attention to this fatal illness, especially when it manifests itself initially as digestive symptoms.

[Association between Helicobacter pylori virulence and duodenal ulcer disease in patients from Hong Kong in China].

Objective: A number of putative virulence factors have been postulated to be relevant to the clinical outcome of Helicobacter pylori infection based on strains identified in the western countries. The aim of this study was to investigate the association between genotypes of vacA, cagA and iceA and duodenal ulcer disease in patients from Hong Kong.

Methods: Seventy-two dyspeptic patients with or without duodenal ulcer disease, with proven H.

[Comparing the Oxygen Free Radicals and Oxygen Consumption of Leukocytes in Leukemia Patients and Healthy Persons].

Using the electron spin resonance (ESR) and probe technique, the species of reactive oxygen free radicals and the oxygen consumption were observed in the metabolic process of oxygen of leukocytes from leukemia patients and healthy persons. Results showed that weak ESR spectrum of hydroxyl radical ((*)OH) signal was detected in the leukemia patient's leukocytes, there was no significant difference in oxygen consumption with or without PMA stimulation; superoxide anion (O(2)) in normal leukocytes was detected, and oxygen consumption increased markedly compared to the normal respiration without PMA stimulation (P < 0.001).
