Background: There is no gold standard for the diagnosis and monitoring of inflammatory bowel disease (IBD).As immune system plays crucial role in the pathogenesis of IBD,some immune-specific serum antibodies are considered to be useful tools for the diagnosis and differential diagnosis of the disease.Aims: To investigate the clinical significance of serum antibodies,including anti-Saccharomyces cerevisiae antibody (ASCA) and perinuclear anti-neutrophil cytoplasmic antibody (pANCA) in IBD.Methods: Serum samples were obtained from 91 consecutive IBD patients from Feb.2015 to May 2016 at the First Affiliated Hospital of Soochow University.Of them,52 were Crohn's disease (CD) and 39 were ulcerative colitis (UC).Serum samples of 36 non-IBD patients were served as controls.ASCA-IgG and ASCA-IgA were detected by ELISA,and pANCA by indirect immunofluorescence assay.Using clinical diagnosis as gold standard,crosstabs statistics was performed to measure the diagnostic accuracy of ASCA and pANCA,and ROC curve,Pearson Chi-square test and Fisher's exact test were employed for analyzing the correlations of these two serum antibodies with IBD,CD,UC,and the location of the disease.Results: Both serum ASCA-IgG and IgA were correlated with CD (AUC=0.626 and 0.614),while UC was correlated with ASCA-IgA only (AUC=0.486).Serum pANCA had relevance to IBD (r=0.342),CD (r=-0.262) and UC (r=0.614);its sensitivity and specificity for IBD and UC were superior to those for CD (P<0.05).In CD patients,ASCA-IgG was associated with terminal ileal disease (P<0.05),and pANCA was associated with colonic involvement (P<0.05).In UC patients,both ASCA-IgG and IgA were correlated with terminal ileal disease (P<0.05).Conclusions: Serum ASCA and pANCA may be helpful for discrimination between CD and UC when the diagnosis of IBD is established.Furthermore,they are closely associated with the disease location,ASCA is related with the terminal ileal disease and pANCA is related with colonic involvement.

OBJECTIVE: To study the function of Qiyeling Decoction in inducing apoptosis of transplanted human lung adenocarcinoma cells A549 in nude mice. METHODS: Nude mice with transplanted A549 tumor were randomly divided into the untreated control group (group A), chemotherapy treated group (group B), chemotherapy plus Qiyeling Decoction treated group (group C), Qiyeling Decoction treated group (group D) and managed correspondingly. The tumor volume was measured and calculated into tumor weight. The apoptosis of tumor cells were examined using in situ cell apoptosis detection kit. RESULTS: The tumor weight was lower obviously in groups B, C and D than that in group A (P<0.05). The apoptosis of tumor cells was lower obviously in groups B, and C than that in group D (P<0.05). Cells in group A appeared perfect differentiation during the early stage and apoptosis later. CONCLUSION: Qiyeling Decoction can induce A549 cell apoptosis in nude mice.

ObjectiveTo discuss the central modulating mechanisms while acupuncturing the Stomach 36[ST36(Zusanli)]by brain functional imaging with positron emission tomography (PET).MethodsPET imaging of whole brain was performed in a group of six healthy subjects during two stimulation paradigms: pseudo acupuncture and real acupuncture at acupoint ST36(Zusanli). The data on cerebral glycometabolism,obtained by using PET,was analyzed by using statistical parametric mapping (SPM).ResultsThere was certain increase of glycometabolism in ipsilateral hypothalamus,back of medulla oblongata;bilateral insular lobe; contralateral paracentral lobule,superior part of precentral and postcentral gyrus,opercular part of frontal and temporal lobe,middle part of cingulate gyrus,head of caudate nucleus,middle part of the back of midbrain and pons,and deep part of cerebellum,whereas decrease in ipsilateral superior part of precentral and postcentral gyrus and lateral part of ipsilateral anterior cerebellar lobe,while acupuncturing at acupoint ST36(Zusanli on the right leg).ConclusionsThe central modulating mechanisms of acupuncturing ST36 are realized by neural and neuroendocrine network modulation mechanisms of vegetative nerve center in cortex and subcortex.
