1Colonoscopic yield of colorectal neoplasia in daily clinical practice显示文摘AIM:To assess the prevalence and location of ad-vanced neoplasia in patients undergoing colonoscopy,and to compare the yield per indication.METHODS:In a multicenter colonoscopy survey (n = 18 hospitals) in the Amsterdam area (Northern Holland),data of all colonoscopies performed during a three month period in 2005 were analyzed. The location and the histological features of all colonic neoplasia were recorded. The prevalence and the distribution ofadvanced colorectal neoplasia and differences in yield between indication clusters were evaluated. Advanced neoplasm was defi ned as adenoma > 10 mm in size,with > 25% villous features or with high-grade dyspla-sia or cancer.RESULTS:A total of 4623 eligible patients underwent a total colonoscopy. The prevalence of advanced neo-plasia was 13%,with 281 (6%) adenocarcinomas and 342 (7%) advanced adenomas. Sixty-seven percent and 33% of advanced neoplasia were located in the distal and proximal colon,respectively. Of all patients with right-sided advanced neoplasia (n = 228),51% had a normal distal colon,whereas 27% had a syn-chronous distal adenoma. Ten percent of all colono-scopies were performed in asymptomatic patients,7% of whom had advanced neoplasia. In the respective procedure indication clusters,the prevalence of right-sided advanced neoplasia ranged from 11%-57%. CONCLUSION:One out of every 7-8 colonoscopies yielded an advanced colorectal neoplasm. Colonoscopy is warranted for the evaluation of both symptomatic and asymptomatic patients.Jochim S Terhaar sive Droste Mike E Craanen Rene WM van der Hulst Joep F Bartelsman Dick P Bezemer Kim R Cappendijk Gerrit A Meijer Linde M Morsink Pleun Snel Hans ARE Tuynman Roy LJ van Wanrooy Eric IC Wesdorp Chris JJ Mulder 2009World Journal of Gastroenterology2009,15,9:6

3油炸食品与心血管病风险和全因死亡率的关系:观察性研究的荟萃分析显示文摘研究者进行了一项荟萃分析,包括剂量反应分析,以定量确定油炸食品摄入与普通成年人群心血管病风险和全因死亡率之间的关系。方法:研究者在PubMed、EMBASE和Web of Science上检索2020年4月11日之前的所有文章。应用随机效应模型估计总的相对危险度(relative risks,RR)和95%CI。结果:与最低油炸食品摄入量相比,最高摄入量者主要心血管事件的总RR(95%CI)=1.28(1.15~1.43),n=17,I^(2)=82.0%,其中前瞻性研究:1.24(1.12~1.38),n=13,I^(2)=75.7%.刘青(译) 练桂丽(审校) Qin P Zhang M Han M Liu D Luo X Xu L Zeng Y Chen Q Wang T Chen X Zhou Q Li Q Qie R Wu X Li Y Zhang Y Wu Y Hu D Hu F 2021中华高血压杂志2021,29,2:3
4Successful operation of a cooperative SLR station of China and Argentina in San Juan显示文摘We introduced the observations and researches using a Satellite Laser Ranging (SLR) system with high precision, which was designed and made in China and installed in the Observatory of San Juan Uni- versity, Argentina, the capability of the system and the achievement of the cooperative procedure be- tween China and Argentina. The SLR station in San Juan, set up by China and Argentina, is quite sig- nificant for improving the distribution of SLR stations and enhancing the orbital coverage of the whole earth. Since the SLR system started to work in the Observatory of San Juan University in the beginning of 2006, the operation is rather good, and rich data with high precision have been obtained. Further plan of the cooperation for the near future is also presented.HAN YanBen LIU WeiDong E ACTIS R PODESTA WANG TanQiang GUO TangYong QU Feng A M PACHECO A A GONZALEZ E ALONSO XIANG QingGe HUANG DongPing YIN ZhiQiang 2008Chinese Science Bulletin2008,53,16:2
