目的分析吸烟与男性新兵肾小球高滤过的相关性.方法横断面研究某部2023年1898名男性新兵,依据不同吸烟状态、不同估算肾小球滤过率分类,通过二分类多元logistic回归分析评估对估算肾小球滤过率的影响.结果单因素分析显示,估算肾小球滤过率与吸烟、吸烟指数、体重指数、收缩压、舒张压、心率、红细胞、肌酐存在统计学意义(P<0.05).多元logistic回归分析显示,相比不吸烟者,吸烟与肾小球高滤过独立相关(OR=2.029,95%CI:1.104~3.731),肾小球高滤过概率呈2倍以上;较轻度吸烟指数者,重度吸烟指数与估算肾小球滤过率相关(OR=2.497,95%CI:1.010~6.175).结论吸烟是男性入伍新兵估算肾小球滤过率的影响因素,与肾小球高滤过独立相关.

Salt stress and flowering time are major factors limiting geographic adaptation and yield productivity in soybean(Glycine max).Although improving crop salt tolerance and latitude adaptation are essential for efficient agricultural production,whether and how these two traits are integrated remains largely ***,we used a genome-wide association study to identify a major salt-tolerance locus controlled by E2,an ortholog of Arabidopsis thaliana GIGANTEA(GI).Loss of E2 function not only shortened flowering time and maturity,but also enhanced salt-tolerance in soybean.E2 delayed soybean flowering by enhancing the transcription of the core flowering suppressor gene E1,thereby repressing Flowering Locus T(FT)*** E2 knockout mutant e2^(CR) displayed reduced accumulation of reactive oxygen species(ROS)during the response to salt stress by releasing peroxidase,which functions in ROS scavenging to avoid *** and population genetic analyses also suggested that loss-of-function e2 alleles have been artificially selected during breeding for soybean adaptation to high-latitude regions with greater salt *** findings provide insights into the coupled selection for adaptation to both latitude and salt stress in soybean;and offer an ideal target for molecular breeding of early-maturing and salt-tolerant cultivars.

Primary pure squamous cell carcinomas(SCC) of the duodenum are very uncommon. To the best of our knowledge, only a few cases of SCC of the duodenum exist in the reported literature. Here, we report a case of SCC of the duodenum in northern China. A 45-year-old Chinese Han male patient presented with abdominal pain and weight loss. CT, endoscopic examinations, X-rays, and immunohistochemical markers were used to confirm this rare diagnosis of SCC. We performed a pancreaticoduodenectomy with a curative intention. However, histological examination revealed SCC of the duodenum. Postoperative chemotherapy was started after surgery. To the best of our knowledge, pancreaticoduodenectomy is the preferred form of treatment for carcinoma of the duodenum. This is supplemented with chemotherapy, which can further prolong survival.

随着经济全球化和区域一体化的快速发展,城市间的交流日益密切,要素的流动性和互赖性促进了城市网络的形成,并成为一种新的区域组织模式和空间结构。本文基于2018年腾讯人口迁徙数据,构建了372×372关系数据矩阵,并从不同交通方式出发,系统刻画了中国城市网络格局。研究表明:①网络关联度高的城市主要集中在胡焕庸线以东区域,尤其是长三角、珠三角、京津冀、成渝等城市群地区的聚集程度最高,成为中国城市网络格局的主控力量;而西北半壁的城市处于被支配地位。②依据迁徙量,将中国城市网络划分为国家级、大区级、区域级、地方级和基座级网络。城市网络结构随交通方式而变化,当网络等级下移时,节点城市趋于增多,网络密度加大,但网络范围趋于缩小,网络等级与迁徙路径存在着密切的关联性,国家级网络与空运相关,区域级网络与铁路运输相呼应,地方级网络与汽车运输相关。③不同运输方式的经济时空距离决定了网络结构,是引致网络随路径不同而产生分异的基本因素。
