1Patients with inflammatory bowel disease have increased risk of autoimmune and inflammatory diseases显示文摘AIM To investigate whether immune mediated diseases(IMD) are more frequent in patients with inflammatory bowel disease(IBD).METHODS In this population based registry study,a total of 47325 patients with IBD were alive and registered in the Danish National Patient Registry on December 16,2013. Controls were randomly selected from the Danish Civil Registration System(CRS) and matched for sex,age,and municipality. We used ICD 10 codes to identify the diagnoses of the included patients. The IBD population was divided into three subgroups: Ulcerative colitis(UC),Crohn's disease(CD) and Both the latter referring to those registered with both diagnoses. Subsequently,odds-ratios(OR) and 95%CI were obtained separately for each group and their respective controls. The use of Bonferoni post-test correction adjusted the significance level to P < 0.00125. P-values were estimated using Fisher's exact test.RESULTS There were significantly more women than men in the registry,and a greater percentage of comorbidity in the IBD groups(P < 0.05). Twenty different IMDs were all significantly more frequent in the IBD group. Sixteen were associated with UC versus twelve with CD. In both UC and CD ORs were significantly increased(P < 0.00125) for primary sclerosing cholangitis(PSC),celiac disease,type 1 diabetes(T1D),sarcoidosis,asthma,iridocyclitis,psoriasis,pyoderma gangrenosum,rheumatoid arthritis,and ankylosing spondylitis. Restricted to UC(P < 0.00125) were autoimmune hepatitis,primary biliary cholangitis,Grave's disease,polymyalgia rheumatica,temporal arteritis,and atrophic gastritis. Restricted to CD(P < 0.00125) were psoriatic arthritis and episcleritis. Restricted to women with UC(P < 0.00125) were atrophic gastritis,rheumatoid arthritis,temporal arteritis,and polymyalgia rheumatica. Restricted to women with CD were episcleritis,rheumatoid arthritis,and psoriatic arthritis. The only disease restricted to men(P < 0.00125) was sarcoidosis. CONCLUSION Immune mediated diseases were significantly more frequent in patients with IBD. Our results strengthen the hypothesis that some IMDs and IBD may have overlapping pathogenic pathways.Morten L Halling Jens Kjeldsen Torben Knudsen Jan Nielsen Lars Koch Hansen 2017World Journal of Gastroenterology2017,23,33:9
2Holocene tephra deposits in the northern Okinawa Trough显示文摘The mineralogical and geochemical characteristics of sediments of Core CSH1, which was collected from the northern Okinawa Trough, indicate that large amounts of volcanic materials have deposited in the northern Okinawa Trough during the Holocene. On the basis of down-core variations in mineral and element contents of sediments, two layers in the uppermost section of Core CSH1 charac- terized by high quartz, Na2O, MnO, K2O, uranium contents and low contents of clay minerals, volatiles, Fe2O3, MgO, CaO and stron- tium, have been identified as the tephra deposits. Systematic grain-size measurements also suggest that sediments from the northern Okinawa Trough are made up of terrigenous materials and volcanic ashes with different proportion during the Holocene. The sedi- ments of tephra layers in Core CSH1 show bi-modal patterns in grain-size distribution with modal grain-sizes of 74.3 and 7.81 μm, respectively. According to the radiocarbon dating on shells of zooplankton foraminifera, two tephra layers in Core CSH1, formed at 7 250 and 10 870 a BP (cal), approximately correspond to the K-Ah tephra [7 300 a BP (cal)] and the eruption of Kuju Volcano (12 ̄10 ka BP), respectively.LIU Yanguang OLE BjФrslev Nielsen ZHANG Deyu DU Dewen JAN Heinemeier WU Yonghua 2006Acta Oceanologica Sinica2006,25,1:4

11关节腔和静脉联合应用氨甲环酸显著降低人工膝关节出血量:一项随机双盲对照试验显示文摘关节腔或者静脉应用氨甲环酸显著降低人工膝关节出血量,两种方式同时应用还没有文献报道。作者将60例患者随机分为两组,一组为关节腔和静脉联合应用氨甲环酸(实验组,30例),术前静脉应用1g氨甲环酸,手术切口缝合后将3 g氨甲环酸溶于100 ml生理盐水注入关节腔;另一组为对照组(30例),术前静脉应用1 g氨甲环酸,手术切口缝合后将100 ml生理盐水注入关节腔。24 h失血量:实验组为466 ml ±313 ml,对照组为743 ml ±358 ml;第2天失血量:实验组为644 ml ±382 ml,对照组为1017±519 ml。两组术后90 d 内均未见血栓形成。因此作者认为,关节腔和静脉联合应用氨甲环酸比单纯静脉应用氨甲环酸可以减少大约37%失血量。Nielsen C S Jans φ φrsnes T 胡孔足 2016临床骨科杂志2016,19,3:1
