AIM:To observe the effect of Jianwei Yuyang Granule(Radix Bupleuri,Radix Codonopsis,Rhizoma Atractylodis macrocephalae,Rhizoma Corydalis,etc.) on the expressions of PS_2 and platelet activating factor(PAF) of helicobacterpylori-associated gastritis and study the potential mechanisim. METHODS:80 cases were divided into two groups.Jianwei Yuyang Granule group(42 cases) was given Jianwei Yuyang Granule and the control group(38 cases) was given three kinds of western medicines combined.H.pylori was detected by urease test on biopsy specimen of gastric mucosa and Warthin-Starry method and the changes of expressions of PS_2 and platelet activating factor(PAF) were observed.The contents of aninohexose and phosphatide in gastric mucosa were determined at the same time.All patients were rechecked gastroscope in the 6th week. RESULTS:The total effect rate of Jian-wei Yuyang group was higher than that of the control group(P

Objective To investigate the effect of hydroxycam ptothecine on PS2 and COX-2 in nude mice by human bile duct carcinoma QBC939 cells in order to analyze the correlation between PS2 and COX-2 expressions and the development of the tumor.Methods After the model of the transplanted tumor of subcutaneous tissues located the nude mice was constructed by human bile duct carcinoma QBC939 cells,30 nude mice were randomly divided into 3 groups,namely,control group,hydroxycamptothecine low-dose group and high-dose group.The growth of the transplanted tumor was observed and immunohistochemical staining combined with image analysis was used to determine the expression of PS2 and COX-2 in the tumor tissues.Results Compared with that of the control group,the content of PS2 in the tumor tissues was increased in hydroxycamptothecine low-dose group and high-dose group.The content of COX-2 was decreased and the growth of the transplanted tumor was inhibited in both hydroxycamptothecine low-dose group and high-dose group(P

AIM: To investigate the potencional mechanism of Sea Buckthorn Procyanidins(SBPC) against peptic ulcer. METHODS: 72 gastric ulcer patients(final diagnosis by gasroscope),were randomly divided into two groups,including Sea Buckthorn Procyanidins(SBPC) treatment group(36 cases),and Ranitidine control group(36 cases),among them,50 Hp-positive PU patients were confirmed by endoscopy,histological instection,urease test.Normal group was 12 cases.Detection on Biospy specimens of gastric mucosa was used to observe the change of ITF for Immunohischemical,PS_2 for western blotting and the contents of aninohexose and phosphatide in ulcerated gastric mucosa. RESULTS: The contents of aninohexose,phosphatide of PU patients increased in sea buckthorn procyanidins(SBPC) group.There was a linear correlation between the contents of phosphatide,aninohexose and the expression of ITF、PS_2 in PU patients(P

Objective Rho signaling component α-catulin,is a cytoskeletal linker protein and plays an important role in apoptotic and senescence resistance,cytoskeletal reorganization,mobility,invasion and epithelial to mesenchymal transition(EMt)of cancer cells. Methods Here,we ex-amined α-catulin expression in squamous epithelium,dysplasia and cancer of head and neck on tissue microarrays by immunostaining. Its expres-sion was compared with clinicopathological parameters and survival rate of cancers. Results It was found that α-catulin expression level was signifi-cantly higher in primary cancers than that in normal squamous epithelium and dysplasia(P < 0.05),but not significantly correlated with aggressive behaviors or adverse prognosis of HNSCC patients(P > 0.05). Cox′s proportional hazard model indicated that distant metastasis and tNM staging were independent prognostic factors for overall survival of the patients with head and neck squamous carcinoma(HNSCC,P < 0.05). Conclusion these findings suggested that up-regulated expression of α-catulin protein may play an important role in the pathogenesis of HNSCC,which might be employed as a potential marker for tumorgenesis of HNSCCs.
