ABSTRACT
Objective To study the effect of the deferoxamine mesylate on the prognosis of patients with intracerebral hemorrhage(ICH) after one year. Methods From February 2013 to May 2014,spontaneous ICH patients diagnosed by computed tomography ( CT ) within 18 hours of onset in Mancheng District Hospital of Baoding were evaluated. Patients were randomly divided into experimental group and control group. The treatment of the two groups was similar except that the experimental group received deferoxamine mesylate. Patients were e?valuated by CT and neurology scale( NIHSS scale,GCS scale) at the time of admission and followed up for the first year by the RANKIN( mRS) scale. All clinical data of the two groups were compared. Results Forty?two patients were included in the study, including 21 cases in the experimental group and 21 cases in the control group,there was no significant difference in baseline data between the two groups at admission. There were 6 pa?tients with mRS ≥3 in the experimental group, and 6 patients with mRS ≥3 in the control group after one year. There was no statistically significant difference in the distribution of mRS score between the two groups after one year admission( P=1. 000) . Conclusion There may be no helpful on the prognosis of patients with intrace?rebral hemorrhage by intravenous infusion of deferoxamine mesylate,the further study is needed.
ABSTRACT
Objective To evaluate the clinical value of OLGA (Operative Link on Gastritis Assessment) system in pathological assessment of gastric mucosa from Chinese patients.Methods Endoscopic and pathological data of patients,who underwent the endoscopic examination of upper gastrointestinal tract from 2007 to 2012,were analyzed.Using the Sydney protocol,we graded atrophy and staged the Helicobacter pylori infection status in gastric biopsies from 108 patients with dyspepsia.We applied the OLGA system to assess the relationship between OLGA staging and grading and dysplasia/cancer,and the relationship between OLGA grading and Helicobacter pylori infection.Results Two cases of early gastric adenocarcinoma were detected at stage Ⅱ and Ⅳ,respectively.The detection rates of precancerous lesions (including intestinal metaplasia and dysplasia) in cases clustered in stages Ⅲ-Ⅳ were significantly higher than those in stages 0-Ⅱ (intestinal metaplasia:100.0％ VS 65.3％,P ＜0.001 ;dysplasia:77.8％ VS 13.9％,P ＜0.001,respectively),and there were significant differences between OLGA staging and the degree of dysplasia (r =0.671,P ＜0.001).In the subjects at stage 0-Ⅱ,we observed only 10 cases (13.9％) of mild dysplasia.The difference in rate of Helicobacter pylori infection was significant at different OLGA grade (P ＜ 0.001),and the correlation between OLGA grading and infection degree of Helicobacter pylori was significant (r =0.586,P ＜ 0.001).Conclusion Precancerous lesions and gastric adenocarcinoma tend to be discovered in patients clustered at high-risk (Ⅲ-Ⅳ) OLGA stages.OLGA staging of dysplasia can effectively differentiate the risks of gastric cancer.The OLGA grading system is consistently associated with the Helicobacter pylori infection.
ABSTRACT
Objective To evaluate the effect of pronase on amoxicillin and metronidazole concentrations in gastric tissue. Methods C57BL/6 mice were randomly divided into experimental group ( n = 70 ) and control group ( n = 70 ) . Amoxicillin ( 28. 6 mg/kg ) , metronidazole ( 22. 5 mg/kg) and omeprazole (138.2 mg/kg) were administered orally to C57BL/6 mice, combined with pronase (110 mg/kg) or same amount of sterile PBS. Gastric tissue and blood plasma samples were taken at 10 point-in time (7 mice/time) from 15 min up to 360 min after administration. Concentrations of amoxicillin and metronidazole were detected by high performance liquid chromatography. Gastritis index of gastric mucosa ( hematoxylin-eosin staining) and the gastric tissue expressions of mucin 5 AC (Western blot) were detected at 120 min and 360 min after administration. Results The time to peak concentration of amoxicillin and metronidazole in gastric tissue appeared earlier than that in blood plasma (15 min vs 60 min). Tissue concentrations of amoxicillin and metronidazole of experimental group were significantly higher than those of control, and they were mainly at 15 min to 90 min (P ＜0. 05). Plasma concentrations of amoxicillin and metronidazole of experimental group at 15 min and 30 min were higher than those of control ( P ＜ 0. 05 ). There was no difference in gastritis index between experimental group and control at 120 min and 360 min after administration (0.28±0. 18 vs 0. 14 ±0. 14,P＞0.05; 0. 43 ±0. 20 vs 0. 28 ±0. 18,P ＞0. 05). The expressions of mucin 5 AC in experimental group were lower than those of control ( 0. 036 ± 0. 006 vs 0. 197 ± 0. 058; P ＜0. 05; 0. 039 ± 0. 008 vs 0. 208 ± 0. 072, P ＜ 0. 05 ). Conclusions Pronase can significantly enhance the drugs penetration from mucus into gastric tissue. Concentrations of amoxicillin and metronidazole of experimental group in local gastric tissue and plasma are higher than those of control, especially in improving concentrations of gastric tissue and prolongation of exposed time.
ABSTRACT
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 biopsy specimens were treated with HE staining, Masson staining, Congo red staining and Warthin-Starry staining.Patients' clinical data was discussed and followed up.Results A twenty-year-old girl had intermittent epigastric pain for 4 years, abdominal distention, hiccup and weight loss for two months.The gastric endoscopy revealed diffuse white nodular appearance of the mucosa in angular incisure and antrum.Pathologic examination of the gastric biopsies from the antrum and angular showed a subepithelial collagen deposition with moderate infiltrates of lymphoplasma cells and eosinophils of the lamina propria.The collagen band measured up to 120.3 μm (mean 43.8 μm).Prednisone 20 mg/d for 4 weeks led to clinical remission and weight gain.Conclusion There are about 40 cases in literatures to date, and the cause and pathogenesis of collagenous gastritis remain unknown.According to the clinical and pathological characteristics, the patient in this article is the subtype of collagenous gastritis that occurring in children and young adults.Specific therapy has not been established, the gluten-free diet and glucocorticosteroid may be helpful to relieve symptoms in collagenous gastritis patients.
ABSTRACT
Objective To investigate the potential mechanism for symptoms related to epigastric discomfort in patients without Helicobacter pylori (H.pylori) infection.Methods Patients who underwent gastric endoscopy and conformed H.pylori negative by histologic examination were enrolled.Among them,232 adult patients were collected between August 2006 and November 2006 and 31 children were collected between September 2005 and August 2009.All patients showed no apparent abnormality by endoscopic examination.The endoscopic biopsy was examined with HE or Warthin-Starry staining.Results In adult group,arteriole obstruction was found in 16 (8.8%) cases and focal haemorrhage in 82 (45.6%) cases.Both were existed in 82 (45.6%) cases.The histopathologic findings showed that arteriole obstruction in transition zone (65.2 %,P = 0.159) was common,whereas the focal haemorrhage in gastric fundus and corpus (65.6%,P=0.001) was in predominance.The symptom of heartburn was less in patients with arteriole obstruction and/or focal haemorrhage in comparison with those without these changes (x2 =8.564,P=0.003).In adolescent group,arteriole obstruction and/or focal haemorrhage accounted for 96.8% (30/31).Conclusion Gastric mucosa ischemic resulted from arteriole obstruction are commonly seen in both adult and adolescent patients,which is an important reason for epigastric discomfort in H.pylori negative patients.
ABSTRACT
Objective To study the effect of restraint and watered stress of different durations on the gastric empting in rats. Methods 48 male SD rats (weight ±150 g) were divided randomly into 6 groups with 8 in each. The experimental rats were restrained and watered in 23℃ water box for 1 h/d, while the controls were free. The body weight, general conditions and behavioral indexes of the rats were observed and recorded. The gastric empting rate was measured in rats with semi-solid diet after 3 d,7 d and 28 d during the statistically significant differences among different groups of different stress groups,and between the 3 d test group and 3 d control group. The gastric empting rate was higer in the 7-day test than in 7 d controlled group, lower in the 28 d test group than 28 d control group. Conclusion Different chronic stress can cause changes of gastric empting rate. With the prolonging of stress time, the empting rate is rising and then decending.
