ABSTRACT
Objective To investigate the clinical value of anti-nuclear antibody(ANA) and anti-nuclear antibody spectrum(ANAs) detection.Methods A total of 2 325 patients with or suspected with autoimmune diseases(AID) were enrolled and detected for ANA and ANAs by using indirect immunofluorescence assay(IIF) and linear immunoblot assay(LIA) respectively.All detected results were analyzed.Results Among 2 325 patients,896 cases(38.54%) were positive with ANA,with positive rate of 45.46% in female patients,which was higher than the 18.46% of male patients(P<0.05),and the common fluorescence patterns were nuclear particle pattern,nuclear homogeneous pattern and the nucleolus pattern.816 cases(35.10%) were positive with ANAs,and the positive rates of anti-Sjogren's syndrome(SS)-B antibody,anti Ro-52 antibody and anti SS-A antibody were relatively higher.The consistency rate of the two methods was 91.66%.Conclusion ANA and ANAs detection could be with certain correlation,but might be not completely consistent,detection could improve the detection rate and reduce the missed detection rate.
ABSTRACT
Objective To invcstigate the effects of Maixiansan on insulin-like growth factor binding protein 7 (IGFBP7) and apoptosis in rats with ulcerative colitis related colorectal cancer.Methods The rat model of ulcerative colitis-related coloreetal cancer was induced by dextran sulfate sodium (DSS) and azoxymethane(AOM). 40 male SD rats [weight (160 ± 10) g] were randomly divided into 4 groups: model, Maixiansan and Meisalazine treatment as well as normal group peritoneally irjected with saline.The expression of IGFBP7 and apoptosis in coloreetal tissue were detected by real-time PCR and TUNEL after 16 weeks. Results The numbers of colorectal cancer in model group( 1.2 ± 0.4 ),in Maixiansan group ( 0.70 ± 0.15 ),in Meisalazine group ( 0.60 ± 0.16 )were higher than in normal control (P ＜ 0.05), but no differences were found among model,Maixiansan and Meisalazine groups(P＞0.05).The apoptosis in colonic mucosa for Meixiansan(8.70±3.47) group and Mesalazine group were enhanced as compared with that in model group( 1.20 ±0.26 vs.0.38±0.11,P＜0.05).The mRNA expression of IGFBP7 in colon for Meixiansan group were higher than those in model group,Meisalazine group,and normal control(50.5 ± 14.0 vs.18.0 ±3.9 and 39.3±11.4,46.4±6.0,P＜0.05). Conclusions Maixiansan may resist the occurrence and development of ulcerative colitis-related colorectal cancer through upregulating IGFBP7 expression of colorectal tissue and promoting apoptosis of tumor cell.
ABSTRACT
It expounds the knowledge of causa morbi and mechanism of insomnia, viewing that it is the result of complex reasons functioning to the body, its attack is to some extent related with individual constitution and characteristics, its mechanism is multiple too, the pathology shows deficiency, heat, sputum and stasis.
