The effect of early Helicobacter pylori eradication on the healing of ESD-induced artificial ulcers: A retrospective study.

Background: The role of Helicobacter pylori eradication is still not clear in endoscopic submucosal dissection (ESD)-induced artificial ulcer. This study investigates the therapeutic effects of H. pylori eradication on ESD-induced artificial ulcers.

Iatrogenic Gastrointestinal Perforation Following Therapeutic Endoscopic Procedures: Management and Outcome.

The aim of this study was to analyze the location, the cause and treatment of iatrogenic gastrointestinal perforations following therapeutic endoscopic procedures. Perforation occurred in 12 patients out of 3,389, giving cases occurred intraoperatively or postoperatively. Among them, 6 cases were closed by titanium clipping and 1 case by purse string suture.

A comparison of endoscopic submucosal dissection (ESD) and radical surgery for early gastric cancer: a retrospective study.

Background: Endoscopic submucosal dissection (ESD) has become one of the mainstays of treatment for early gastric cancer (EGC). Radical surgery is also a classical treatment method for EGC. There have been no systematic clinical studies of the curative effects and adverse events associated with ESD vs.

CagA status & genetic characterization of metronidazole resistant strains of H. pylori from: A region at high risk of gastric cancer.

Objective: The aim of study was to determine relationship between cagA and genetic characterization of metronidazole (MTZ) resistant H. pylori strains from a region at high risk of gastric cancer.

Methods: 172 H.

Standard triple, bismuth pectin quadruple and sequential therapies for Helicobacter pylori eradication.

Aim: To compare the effectiveness of standard triple, bismuth pectin quadruple and sequential therapies for Helicobacter pylori (H. pylori) eradication in a randomized, double-blinded, comparative clinical trial in China.

Methods: A total of 215 H.

[Preliminary study on the association of lanthanum and phosphorous loss from soil].

Through laboratory lysimeter experiments and artificial rainfall experiments, characteristics of P and La transportation from both vertical and horizontal directions are investigated. The association between La and P loss from soil is preliminarily discussed. Results of lysimeter experiment show that both La and P are difficult to transport vertically.

[Comparison of characteristics of heavy metals in different grain sizes of intertidalite sediment by using grid sampling method].

384 surface sediment samples were collected from mud flat, silt flat and mud-silt flat of Bohai Bay by 1 m and 10 m interval using grid sampling method. Concentrations of Al, Fe, Ti, Mn, Ba, Sr, Zn, Cr, Ni and Cu in each sample were measured by ICP-AES. To figure out the random distribution and concentration characteristics of these heavy metals, concentration of them were compared between districts with different grain size.

[Molecular mechanism of gastrin increasing colon cancer cells' invasion].

Objective: To explore the molecular mechanism of increasing the invasion of colon cancer cells by gastrin 17.

Methods: The plasmid pCR 3.1/GR expressing the gastrin receptor cholecystokinin-2 receptor (CCK-2R) was transfected into colonic carcinoma cells of the line Colo320 by Lipofectamine 2000.

[The role of p38 MAPK in gastrin-induced u-PA expression in human colon cancer cells].

Objective: To study the effect of gastrin on the mRNA and protein expression of urokinase-type plasminogen activator (u-PA) in human colon cancer cells and detect the role of p38 MAPK in this process.

Methods: Lipofectin method was used to transfect pCR3. 1/CCK2R vector expressing gastrin receptor into a colon cancer cell line colo320.

Endoscopic findings and pathologic characteristics of gastric eosinophilic granuloma: a report of 18 patients.

Aim: To investigate the endoscopic findings and patholo-gic characteristics of gastric eosinophilic granuloma (GEG).

Methods: A retrospective study of 18 cases of gastric eosinophilic granulomas was conducted. Gastroscopy was performed and all specimens of biopsies were stained by HE and observed under light microscopy.
