在素养导向的教育改革背景下,如何评价和改进跨学科实践、项目式教学成为当前国际科学教育共同关注的焦点问题。为回应该问题,通过梳理比较“教育者评估教学产品质量”(EQuIP)量规反映的国际科学教育共性理念,吸收借鉴EQuIP量规部分评价指标,结合跨学科教学改进实践,制订我国的跨学科实践教学评价标准。依托物理学科教学设计评价案例,进一步探讨跨学科实践教学的评价问题。从评价标准的设计思路、研制过程及其保障机制维度来看,研究认为,跨学科实践教学改进应做到:聚焦关键问题,助力学生动态发展;打造跨学科团队,赋能教师专业成长;建设服务平台,推进教育信息化。

Objective Ginkgoales and Czekanowskiales are important components of Mesozoic flora and were widely distributed in the Northern Hemisphere. They are usually preserved together in the stratum. Their fossils are abundant in the Middle Jurassic of Shaanxi Province, but there are no reports on their reproductive organs. Here, we report two male gymnospermous pollen cones from the Middle Jttrassic Yan＇an Formation of the northeast Yulin City, Shaanxi Province, China. The characteristics of the fossils, including those of pollens, have been described in detail. The new specimens were compared with fossils closely similar in morphology, and the taxonomic affinity and systematies were established. The present results offer new fossil materials for the study of taxonomy, evolution, and phytogeography of Ginkgoales and Czekanowskiales.

A Review on the Taxonomic,Evolutionary and Phytogeographic Studies of the Lotus Plant(Nelumbonaceae:Nelumbo)

引用

Acta Geologica Sinica(English Edition) 2014年第4期88卷 1252-1261页

作者： LI Ya Popova SVETLANA yao jianxin LI Chengsen Institute of Geology Chinese Academy of Geological Sciences Key Laboratory of Stratigraphy and Paleontology Ministry of Land and Resources of the People's Republic of China State Key Laboratory of Systematic and Evolutionary Botany Institute of BotanyChinese Academy of Sciences Laboratory of Palaeobotany Komarov Botanical InstituteRussian Academy of Sciences

Nelumbo Adans. （Nelumbonaceae） is an important member of the early-diverging eudicots. It contains two extant species： N. nucifera Gaertn. （the Sacred lotus）, distributed in Asia and Australia and N. lutea Willd. （the American lotus）, occurring in North America. This paper reviews the taxonomic, evolutionary and phytogeographic studies of the genus Nelumbo, and also raises scientific questions about it in further paleobotanic research. There are about 30 fossil species of Nelumbo established since the Early Cretaceous. Based on fossil studies, the ancestors of the extant N. nucifera and N. lutea are respectively considered to be N. protospeciosa from the Eocene to Miocene of Eurasia, and N. protolutea from the Eocene of North American. However, molecular systematic studies indicate that N. nucifera and N. lutea are probably split from a common ancestor during the Late Miocene to Early Pliocene, or even the Pleistocene, rather than separate relicts from extinct species on different continents. The characters of lotus stomatal development, seedling morphology as well as its flowering, pollination and fertilization in air reveal that it evolves from the land plants. Fossil data of Nelumbo indicates that the genus first occurs in mid-latitude area of Laurasia in the Early Cretaceous, then becomes widespread in North America and Eurasia and expands into Africa and South America during the Late Cretaceous; the genus probably colonizes the Indian Subcontinent from Asia during the Early Eocene after the collision of India and the Asian plates; the genus becomes extinct in Europe, but survives in Asia and North America during the Quaternary Ice Age, and later forms the present East Asia and North Australia-North America disjunctive distribution.

Triassic Scleractinian Corals in China：A Review of Present Knowledge

Acta Geologica Sinica(English Edition) 2017年第1期91卷 270-282页

作者： BO Jingfang yao jianxin LIAO Weihua DENG Zhanqiu Institute of Geology Chinese Academy of Geological Sciences Beijing 100037 China Key Laboratory of Stratigraphy and Paleontology Ministry of Land and Resources Beijing 100037 China Nanjing Institute of Geology and Palaeontology Chinese Academy of Sciences Nanjing 210008 China

Scleractinian corals appeared during the Anisian period of the Triassic after the end-Permian mass extinction, which in Triassic were distinct from the Jurassic-Cretaceous scleractinian corals. The study on Triassic scleractinian coral fauna as a separate field is significant for exploring the development and evolution of modern corals and investigating environmental changes since the Mesozoic. The first Triassic coral in China was reported in 1925, and since then, nearly 25 articles dealing with taxonomy and 17 papers about fossil reports on Triassic scleractinian corals in China have been published, which refer to 60 genera and 312 species, 49 localities and 25 strata. In this paper, the history, taxonomy, localities, stratigraphic distribution, current research, and existing knowledge gaps of the Triassic scleractinian corals in China are reviewed. More specifically, the research findings of the Triassic scleractinain coral in China since 1925 are discussed; the species of the Triassic scleractian coral fossil reported in China, has been examined and its synonyms have been sorted out; the geographical distributions of the Middle and Late Triassic scleractinian corals in China are systematically treated; the Triassic coral biostratigraphy in China has been improved; and the stratigraphic ranges of existing genera and species are provided. The above conclusions are presented in the form of complete figures. At the same time, we analyzed shortcomings in current research and identified productive future research directions of the Triassic scleractinian corals in China.

目的探讨弥漫大B细胞淋巴瘤(DLBCL)患者血清脂蛋白a[Lp(a)]的水平及其临床意义。方法回顾性队列研究。回顾性分析2017年1月至2022年6月就诊于常熟市第二人民医院87例DLBCL患者的临床资料(初治DLBCL组),选择健康体检者78名为对照组。比较初治DLBCL组和对照组Lp(a)的水平,及治疗后获得不同疗效的DLBCL患者Lp(a)水平。绘制受试者工作特征(ROC)曲线,分析血清Lp(a)预测DLBCL患者疗效的效能,计算曲线下面积(AUC),确定最佳临界值。根据最佳临界值,将DLBCL患者分为低Lp(a)组和高Lp(a)组,比较不同Lp(a)水平患者的临床病理特征;采用Cox比例风险模型分析DLBCL患者预后的影响因素;采用Kaplan-Meier法比较不同Lp(a)水平DLBCL患者无复发生存(RFS)和总生存(OS)。结果初治DLBCL组患者Lp(a)水平为(0.24±0.09)g/L,对照组为(0.09±0.06)g/L,DLBCL组高于对照组,差异有统计学意义(t=3.61,P=0.019)。87例患者中,治疗后达完全缓解(CR)54例,部分缓解(PR)23例,疾病进展(PD)10例。CR、PR、PD患者Lp(a)水平分别为(0.09±0.09)g/L、(0.12±0.08)g/L、(0.25±0.15)g/L,CR、PR患者Lp(a)水平均低于初治DLBCL患者Lp(a)水平[(0.24±0.09)g/L],差异均有统计学意义(均P0.05)。ROC曲线结果显示,血清Lp(a)预测DLBCL患者疗效的最佳临界值为0.25 g/L,AUC为0.776(95%CI:0.676~0.876,P0.25 g/L)(30例)。高Lp(a)组患者中,乳酸脱氢酶>227 U/L、Ann Arbor分期Ⅲ~Ⅳ期、结外器官受累>1个的患者比例均高于低Lp(a)组,差异均有统计学意义(均P0.25 g/L是影响DLBCL患者OS的独立危险因素(均P<0.05);Ann Arbor分期Ⅲ~Ⅳ期、IPI评分3~5分是影响DLBCL患者RFS的独立危险因素(均P<0.05)。低Lp(a)组中位OS时间未达到;高Lp(a)组中位OS时间为21个月,两组OS比较差异有统计学意义(P=0.001)。低、高Lp(a)组中位RFS时间均为未达到,两组RFS比较差异无统计学意义(P=0.102)。结论DLBCL患者Lp(a)水平升高,Lp(a)可能是影响DLBCL预后的因素。
