SRAP （sequence-related amplified polymorphism） was used for the analysis of 67 sesame （Sesamum indicum L.） cultivars widely used in Chinese sesame major production areas from 1950 to 2007. A total of 561 bands were amplified using 21 SRAP random primer pairs, with 265 of them were polymorphic, resulting in a polymorphism ratio of 47.2%. The total bands and polymorphism amplified by each primer pair averaged 26.7 and 12.6, respectively. The average genetic similar coefficient and genetic distance of the 67 cultivars were 0.9104 and 0.0706, respectively, indicating limited genetic diversity and narrow genetic basis. Comparative analysis on genetic similarity and genetic distance of different classified cultivars showed that the difference of average genetic similarity coefficient and genetic distance between the landraces and cultivars bred through crosses reached significant levels （P=0.01）, with the genetic basis of landraces wider than that bred cultivars. The genetic basis of cultivars used in 1990-2007 was more narrow than that of cultivars from 1950 to 1969 and from 1970 to 1989, with the differences of average genetic similarity coefficient and genetic distance reached 0.01 significant level. The genetic basis of Chinese sesame main cultivars is relatively narrow, and the genetic basis of cultivars developed through crosses in recent years is narrower than history cultivars.

Light-driven nitrogen fixation to produce ammonia is a green and economical technology of nitrogen reduction but is still quite challenging, especially in an air atmosphere without any sacrificial ***, we demonstrate efficient photocatalytic nitrogen fixation using water and air directly by loading lanthanide–transition metal(4f–3d) cluster NdCo_(3) on two-dimensional P-doped graphitic carbon nitrides(PCN) material surface. Benefiting from the increase in the number of nitrogen vacancies(NVs) and highly matched band gap structure and excellent hole trapping ability of clusters, the NdCo_(3)/PCN photocatalyst exhibits efficient nitrogen reduction activity with 371(in air) and 825 μmol h^(-1)g^(-1)(in pure nitrogen)without any sacrificial reagents. The introduction of potassium sulfate inhibits hydrogen production and promotes nitrogen reduction activation. This work suggests that anchoring precisely structured clusters on 2D materials may enhance photocatalytic nitrogen reduction under normal temperature and pressure.

目的将食管癌高发区舌象筛查与内镜筛查相结合,分析食管癌变过程中不同病理状态下舌象特征,探索食管癌前病变向早期食管鳞癌转化的舌象特征规律及中医病机特点。方法纳入河北磁县、四川盐亭、山西阳城地区2017年—2021年完成内镜筛查及舌象筛查的18954例人群,使用道生舌诊仪(DS01-B)在统一标准的光源环境下提取12种舌象特征。使用SPSS 24.0软件进行数据分析,并通过多因素Logistic回归对多种混杂因素进行控制,比较食管癌前病变及早期食管癌与病理正常人群之间的舌象特征差异。结果舌象分布分析显示,紫舌在食管癌前病变及早期食管癌组的比例高于病理正常组,且其在早期食管癌组的比例高于食管癌前病变组,Logistic回归分析结果显示紫舌在食管癌前病变及早期食管癌组的OR值分别为1.82(95%CI:1.45~2.28,P<0.001)、2.14(95%CI:1.51~3.05,P<0.001);红舌与裂纹舌主要在癌前病变组占比较高,其在早期食管癌组的比例略低于癌前病变组,Logistic回归分析结果显示其OR值分别为1.44(95%CI:1.25~1.66,P=0.003)、1.49(95%CI:1.30~1.72,P<0.001)。将其他差异具有统计学意义的舌象特征纳入多因素Logistic回归分析后,结果与前面分析相一致。结论食管癌前病变组紫舌、红色与裂纹舌的比例均高于病理正常组,而早期食管癌组紫舌的比例高于食管癌前病变组,红色与裂纹舌的比例略低于食管癌前病变组,反映出食管癌变过程中由阴虚燥热向瘀血内阻转化的中医病机规律。
