ABSTRACT
Objective: To observe the effect of tripterygium polyglycosid(TP,雷公藤) on airway inflammation and remodeling in rats with asthma.Methods: Forty rats were randomly divided evenly into negative control group,positive control group,normal dose TP group(TPⅠ group) and small dose TP group(TPⅡgroup).The experimental model was induced by ovalbumin sensitization.Number of cells in bronchoalveolar lavage fluid(BALF) was observed by immunocytochemical staining.The expressions of nuclear factor-?B(NF-?B),matrix metalloproteinases-9(MMP-9) and tissue of inhibitor of metalloproteinases-1(TIMP-1) were detected by immunohistochemistry method.Results: Compared with the negative control group,the counts of lymphocyte,neutrophilic leukocyte,macrophage and eosinocyte in BALF were elevated significantly,positive cell percentages of NF-?B, MMP-9 and TIMP-1 in lung tissues increased greatly in positive control group,the differences being significant(all P
ABSTRACT
Objective To investigate clinical feature,diagnosis and prognosis of eosinophilic gastroenteritis(EG),and to analyze the causes of misdiagnosis.Methods Eleven children diagnosed as EG were studied.Their history,clinical manifestations,laboratory tests and endoscopies and treatment,follow-up data were analyzed.The data were analyzed by SPSS 10.0 software.Results 1.The children with EG usually had abdominal pain(5 cases),diarrhea(7 cases),hemafecia(5 cases) and sometimes with fever(2 cases).2.EG and allergy in children was closely related with disease(54.55%).3.Peripheral blood eosinophil(EOS) count increased significantly,and declined when symptoms eased(18.18%).4.Endoscopic manifestations were not specific,the mucosa could see sheet erosion,shallow ulcers,congestive spots or bleeding spots,mainly in antrum,duodenum,terminal ileum,ileocecal junction.The biopsy showed that a large number of EOS infiltration.5.Imaging were not specific,CT or gastrointestinal barium meal examination did not show special often(90.91%).When muscular wall was affected(9.09%),imaging presentations of EG could be partly obstructive.6.Glucocorticoid therapy could relieve symptoms and EOS.Symptoms probably recured by good prognosis.7.EG was a self-limiting allergic diseases,although the attack may be repeated.After long-term follow-up,most had good prognosis and without malignant.Conclusions Clinical and endoscopic presentations of EG are not specific,therefore the presence of EOS in gastrointestinal mucosa strongly indicate the diagnosis.It was easy to misdiagnosis.Biopsy pathology and cli-nical characteristics are the key to diagnosis.
