1南澳岛青澳湾沉积物粒度与烧失量指示的全新世沉积环境变化显示文摘通过对粤东南澳岛青澳湾NA6、NA9号钻孔剖面的岩性、粒度和烧失量特征进行综合分析,结合AMS14 C测年结果,讨论了该地区8 500cal.aBP以来沉积环境的演变过程。结果显示,烧失量反映的有机碳变化与沉积物粒度组分有十分密切的关系,表明海岸带水动力条件的改变与陆源有机碳的富集有关。潮下带淤泥沉积以及滨岸的!湖沉积较有利于有机碳的富集。相反,砂质堆积的有机碳含量较低,与高能的海浪作用有关。钻孔研究表明,该区沉积环境演变主要受全新世海平面变化的控制:8 500~5 500cal.aBP为海平面快速上升期,研究区被海水所淹没为潮下带沉积,沉积物中发现许多完整的近岸海相软体动物,且有机碳含量较高;5 500~3 000cal.aBP为砂质沉积,潮间带砂坪表明海平面稳定或略有下降;3 000~1 300cal.aBP水下沙坝-沙丘沉积,海平面基本稳定在现今高度;1 300cal.aBP以后为湖沉积,最后在洪积物冲积的堆积作用和海退下形成平原。杨冰洁 余凤玲 郑卓 陈碧珊 Adam D Switzer 2015海洋地质与第四纪地质2015,35,6:9
2福建平潭岛晚第四纪沉积序列及MIS 5海侵旋回特征显示文摘选择位于福建平潭岛北部芦洋埔海积平原的PT01钻孔,岩芯长度28.3 m,采用加速器碳同位素(AMS 14C)和光释光(OSL)测年建立地层年代框架,认为晚更新世富含有孔虫等海相生物化石的地层应归属于MIS 5高海面期,即MIS 5e的潮下带滨海相沉积。结合岩性特征、古生物化石、沉积物色度、粒度分析及其参数等指标,进行了沉积单元的划分,重建了MIS 6末期以来的沉积相变化过程,揭示出MIS 5期间的多次海平面波动变化,即MIS 5高海面期沉积环境仍存在滨海、潮坪、潟湖、风成砂等沉积相之间的转换,并可能存在短暂的陆相或风化过程。而该区整个末次冰期的沉积缺失或较薄,上部全新世沉积也不发育,厚度仅为3.79 m,以沼泽相―风成砂相为主。陈聪 万秋池 郑卓 余风玲 A SWITZER 万一兴 2016热带地理2016,36,3:9

4Update on novel endoscopic therapies to treat gastroesophageal reflux disease: A review显示文摘Endoscopic treatments for gastroesophageal reflux disease(GERD) have become increasingly popular in recent years. While surgical intervention with the Laparoscopic Nissen Fundoplication remains the gold standard, two endoscopic interventions, specifically, are gaining traction in clinical use(Esophy X and Stretta). The Esophy X(Endo Gastric Solutions, Inc., Redmond, WA, United States) was developed as a method of restoring the valve at the GE junction through an endoluminal fundoplication(ELF) technique. Long-term data suggests that transoral incisional fundoplication(TIF) with Esophy X may be effective for symptom control and proton pump inhibitor reduction or cessation for up to 2-6 years. There is no evidence that Esophy X is more effective than surgical intervention. TIF may be most effective for patients with HH < 2 cm and Hill Grade I/II valves. Stretta(Mederi Therapeutics, Greenwich, CT, United States) was approved by the Food and Drug Administration in 2000. It delivers radiofrequency energy to the lower esophageal sphincter and gastric cardia. Published reviews of the literature are conflicted in their recommendations of Stretta in the management of GERD. The literature suggests that the Stretta procedure has an acceptable safety profile and may be effective in reducing symptom burden and quality of life scores up to 8 years post-intervention. However, there does not appear to be any sustained improvement in objective outcomes and there is no evidence that Stretta results in improved outcomes as compared to surgical intervention. Treatment modalities for GERD, as a field, suffer from a lack of standardization in primary and secondary outcomes. Although many studies have looked at health related quality of life, the tools used to do so are markedly heterogeneous. Future directions for the endoscopic treatment of GERD include novel techniques like endoscopic submucosal dissection.Jessica Hopkins Noah J Switzer Shahzeer Karmali 2015World Journal of Gastrointestinal Endoscopy2015,7,11:2
