8Status monitoring and health assessment of Luhuitou fringing reef of Sanya, Hainan, China显示文摘The monitoring survey and health assessment for benthic community were carried out in Luhuitou fringing reef of Sanya, Hainan, China in 2002. Monitoring survey included manta tow, line intercept transect, video transect and digital photograph. The mean live coral cover was 23.40%. Comparison of used monitoring methods showed that video transect can replace line intercept transect, and 50 m transect is better than 20 m transect in uneven coral region. Survey data and comparison with previous research work showed that Luhuitou fringing reef has been damaged severely and has a general declining trend with live coral cover from about 85% in the 1960s down to 20% in 2004, but it still has quite high biodiversity and therefore has special protection value. Main factors of Luhuitou fringing reef declining were human activities including reef rock digging and curios collecting, destructive fishing, sediment and pollutant from coastal land, and recent marine aquaculture. Only strengthening integrated management can reach improvement and restoration of Luhuitou declining coral reef ecosystem.ZHANG Qiaomin SHI Qi CHEN Gang FONG T C W WONG D C C HUANG Hui WANG Hankui ZHAO Meixia 2006Chinese Science Bulletin2006,51,B12:15
9帕博利珠单抗(pembrolizumab)与化疗治疗微卫星不稳定性高/错配修复缺陷型转移性结直肠癌的比较:KEYNOTE-177的3期研究显示文摘背景:KEYNOTE-177 (NCT02563002)是一项3期随机、开放标签的临床研究,评估了帕博利珠单抗与标准化疗±贝伐珠单抗或西妥昔单抗作为微卫星不稳定性高/错配修复缺陷(MSI-H/d MMR)型转移性结直肠癌患者一线治疗的效果和安全性。本次公布了终期PFS分析的结果。方法:共有307名由当地医疗机构评判的MSI-H/d MMR且ECOG PS评分为0或1的转移性结直肠癌患者按1:1比例随机分组接受治疗,治疗方案为一线帕博利珠单抗(200 mg,Q3W,最长治疗时限为2年),或为研究者所选择的化疗方案,包括m FOLFOX6或FOLFIRI Q2W±贝伐珠单抗或西妥昔单抗(随机选择化疗方案)。治疗终止于出现PD、无法耐受的毒性、患者/研究者决定退出治疗或完成35个周期治疗(仅对于帕博利珠单抗而言)。确诊PD后,接受化疗组患者可转入帕博利珠单抗组并接受最长为35个周期的治疗。主要终点是PFS (RECIST v1.1,中心审查)和OS。主要的次要终点包括ORR (RECIST v1.1,中心审查)和安全性。该中期分析的数据截止日期是2020年2月19日。该研究仍将继续随访评估OS。结果:截止数据纳入时,153名患者被随机分至帕博利珠单抗组,154名患者被随机分至化疗组。帕博利珠单抗组的中位随访为28.4个月(0.2~48.3个月),化疗组为27.2个月(0.8~46.6个月)。帕博利珠单抗组PFS优于化疗组(中位时间16.5个月vs. 8.2个月;HR=0.60,95%CI:0.45~0.80,P=0.0002)。帕博利珠单抗组的12个月和24个月PFS率分别为55.3%和48.3%,化疗组则相应分别为37.3%和18.6%。帕博利珠单抗组与化疗组经确认的ORR分别为43.8%与33.1%;帕博利珠单抗组与化疗组中位持续反应时间分别为未达到(2.3+~41.4+个月)和10.6个月(2.8~37.5+个月)。帕博利珠单抗组3~5级与治疗相关的不良事件(AE)发生率为22%,化疗组为66%。化疗组中有1例患者因治疗相关的AE死亡。结论:与化疗相比,帕博利珠单抗作为MSI-H/d MMR型转移性结直肠癌的一线治疗可提供具有临床意义和统计学意义的PFS获益,同时观察到较少的与治疗相关的AE,应该成为这类患者的新的标准治疗方案。陈功 ANDRé T SHIU K K KIM T W 2020结直肠肛门外科2020,26,6:15

131999年海城-岫岩地震序列的精准定位显示文摘1999年11月29日,北京时间12点10分39秒(04:10:39UTC)在我国辽宁海城—岫岩地区发生了一次MS5.4地震.这次地震是继1975年2月4日海城MS7.3地震之后该地区发生的震级最大的一次地震.区域性的辽宁数字地震台网记录了这一序列的前震、主震与余震.本文运用该台网的记录资料,用双差法对海城—岫岩地震序列重新定位,得到了该序列事件之间精确的相对位置;然后以中国地震局地球物理研究所(IGCEA)与美国南卫理大学(SMU)合作的辽宁海城—岫岩地区地震试验场宽频带地震台网(BSN)记录的、经过精准定位的地震作为近震源观测的'地面实况'(groundtruth,GT)事件进行校正,得到了这一地震序列的既精确又准确的震源参数.由此得出1999年海城—岫岩地震的发震构造是与1975年海城地震的发震构造海城河—大洋河断裂邻近的康家岭断裂.康家岭断裂的走向与海城河—大洋河断裂走向一致,均为WNW--ESE方向.它们都是在中国东北—华北地区近ENE--WSW向、几乎水平的压应力场作用下产生的断裂.1999年海城—岫岩地震是在海城河—大洋河断裂的影响带动下,邻近的、与其走向一致的康家岭断裂活动的结果.杨智娴 Brian W Stump 陈运泰 Robert B Herrmann Rongmao Zhou Chris T Hayward 2011地震学报2011,33,3:9

16Nationwide trends and predictors of inpatient mortality in 83884 transjugular intrahepatic portosystemic shunt显示文摘AIM: To evaluate and validate the national trends and predictors of in-patient mortality of transjugular intrahepatic portosystemic shunt(TIPS) in 15 years.METHODS: Using the National Inpatient Sample which is a part of Health Cost and Utilization Project, we identified a discharge-weighted national estimate of 83884 TIPS procedures performed in the United States from 1998 to 2012 using international classification of diseases-9 procedural code 39.1. The demographic, hospital and co-morbility data were analyzed using a multivariant analysis. Using multi-nominal logistic regression analysis, we determined predictive factors related to increases in-hospital mortality. Comorbidity measures are in accordance to the Comorbidity Software designed by the Agency for Healthcare Research and Quality.RESULTS: Overall, 12.3% of patients died during hospitalization with downward trend in-hospitalmortality with the mean length of stay of 10.8 ± 13.1 d. Notable, African American patients(OR = 1.809 vs Caucasian patients, P < 0.001), transferred patients(OR = 1.347 vs non-transferred, P < 0.001), emergency admissions(OR = 3.032 vs elective cases, P < 0.001), patients in the Northeast region(OR = 1.449 vs West, P < 0.001) had significantly higher odds of inhospital mortality. Number of diagnoses and number of procedures showed positive correlations with in-hospital death(OR = 1.249 per one increase in number of procedures). Patients diagnosed with acute respiratory failure(OR = 8.246), acute kidney failure(OR = 4.359), hepatic encephalopathy(OR = 2.217) and esophageal variceal bleeding(OR = 2.187) were at considerably higher odds of in-hospital death compared with ascites(OR = 0.136, P < 0.001). Comorbidity measures with the highest odds of in-hospital death were fluid and electrolyte disorders(OR = 2.823), coagulopathy(OR = 2.016), and lymphoma(OR = 1.842).CONCLUSION: The overall mortality of the TIPS procedure is steadily decreasing, though the length of stay has remained relatively constant. Specific patient ethnicity, location, transfer status, primary diagnosis and comorbidities correlate with increased odds of TIPS in-hospital death.Edward Wolfgang Lee Andrew Kuei Sammy Saab Ronald W Busuttil Francisco Durazo Steven-Huy Han Mohamed M El-Kabany Justin P Mc Williams Stephen T Kee 2016World Journal of Gastroenterology2016,22,25:7
17儿童期肥胖、成年期肥胖和心血管风险因子显示文摘过去30年,儿童超重或肥胖的发生率明显增加[1]。儿童期肥胖是死亡率增加的预测因子,这主要是由于儿童期肥胖可导致心血管疾病发生率增加。相关的预测研究提示"肥胖流行症"可能改变目前心血管疾病死亡率下降的趋势,使现今儿童的寿命缩短。Juonala M Magnussen CG Berenson GS Venn A Burns TL Sabin MA Srinivasan SR Daniels SR Davis PH Chen W Sun C Cheung M Viikari JS Dwyer T Raitakari OT 叶鹏 2012中华高血压杂志2012,20,1:6

19D-二聚体预测稳定型冠状动脉性心脏病患者的长期病因特异性死亡率、心血管事件和癌症显示文摘交联纤维蛋白的降解产物D-二聚体是高凝状态和血栓形成事件的标志。D-二聚体水平中度升高与血管疾病患者静脉和动脉事件的风险相关。在缺血性疾病长期普伐他汀干预(long-term intervention with pravastatin in ischemic disease,LIPID)试验中,研究者在存在其他危险因素的背景下,评估了D-二聚体水平在预测长期血管转归、病因特异性死亡率和新发癌症中的作用。刘青 叶鹏 Simes J Robledo KP White HD Espinoza D Stewart RA Sullivan DR Zeller T Hague W Nestel PJ Glasziou PP Keech AC Elliott J Blankenberg S Tonkin AM LIPID study investigators 2018中华高血压杂志2018,26,3:6
20High-density SNP-based genetic maps for the parents of an outcrossed and a selfed tetraploid garden rose cross, inferred from admixed progeny using the 68k rose SNP array显示文摘Dense genetic maps create a base for QTL analysis of important traits and future implementation of marker-assisted breeding.In tetraploid rose,the existing linkage maps include<300 markers to cover 28 linkage groups(4 homologous sets of 7 chromosomes).Here we used the 68k WagRhSNP Axiom single-nucleotide polymorphism(SNP)array for rose,in combination with SNP dosage calling at the tetraploid level,to genotype offspring from the garden rose cultivar‘Red New Dawn’.The offspring proved to be not from a single bi-parental cross.In rose breeding,crosses with unintended parents occur regularly.We developed a strategy to separate progeny into putative populations,even while one of the parents was unknown,using principle component analysis on pairwise genetic distances based on sets of selected SNP markers that were homozygous,and therefore uninformative for one parent.One of the inferred populations was consistent with self-fertilization of‘Red New Dawn’.Subsequently,linkage maps were generated for a bi-parental and a self-pollinated population with‘Red New Dawn’as the common maternal parent.The densest map,for the selfed parent,had 1929 SNP markers on 25 linkage groups,covering 1765.5 cM at an average marker distance of 0.9 cM.Synteny with the strawberry(Fragaria vesca)genome was extensive.Rose ICM1 corresponded to F.vesca pseudochromosome 7(Fv7),ICM4 to Fv4,ICM5 to Fv3,ICM6 to Fv2 and ICM7 to Fv5.Rose ICM2 corresponded to parts of F.vesca pseudochromosomes 1 and 6,whereas ICM3 is syntenic to the remainder of Fv6.Mirjana Vukosavljev Paul Arens Roeland E Voorrips Wendy P C van't Westende G D Esselink Peter M Bourke Peter Cox W Eric van de Weg Richard G F Visser Chris Maliepaard Marinus J M Smulders 2016Horticulture Research2016,3,1:6
