俄罗斯沿岸更新世盆地类型

俄罗斯沿岸地区受到分别属于大西洋、北冰洋和太平洋的14个海的海水冲刷，海岸线的总长度超过60000km。在更新世，这些盆地经历过不止一次的幅度不同的海平面的升降作用。在海退时期，广阔的陆架地区变干了，而在海侵时期，沿岸平原和低山岸区被海水淹没。在东北     

Contamination of organotin compounds and imposex in molluscs from Vancouver,Canada

Gastropods and bivalves were collected at 15 sites at Vancouver and Victoria, Canada between 24 May and 7 June, 1999, to establish tissue concentrations of butyltin and phenyltin compounds, to record imposex symptoms in gastropods, and to assess the present status of organotin contamination around Vancouver. No neogastropods (such as Nucella lima) were found around Vancouver. Neogastropod populations could have been extirpated by severe TBT contamination in Vancouver, as relatively high concentrations of TBT were detected in tissues of Mytilus trossulus from Vancouver, and the neogastropods distributed in Vancouver might be sensitive to TBT. Recovery from imposex, however, was observed in neogastropod populations from three sites at Victoria and Mission Point. TBT contamination has continued around Vancouver, arising from continuous use of TBT in antifouling paints for vessels larger than 25 m in length; however, TBT has decreased around Victoria and Mission Point. Different patterns of TBT accumulation in tissue were observed among the bivalve species from Vancouver. The highest TBT concentration detected in Tresus capax suggested some possible adverse effects. TBT was the most predominant butyltin component in almost all bivalve specimens surveyed, suggesting a low rate of TBT metabolism. Phenyltin compounds were not detected in any molluscan specimens in this study.     

朱明芳从肝脾论治扁平疣经验

介绍朱明芳教授从肝脾论治扁平疣的经验。朱教授认为扁平疣发病之本责之肝、脾二脏,多种内外因素作用使肝郁失养或脾虚湿蕰,故其在临床治疗上多采用疏肝开郁、健脾益气之法,并自创调肝消疣方与运脾消疣方治之。同时结合中医学象思维,以形治形,增强消疣之功。该法在临床上取得了良好的疗效,另附验案1则,以资佐证。     

基于应激性心肌病再论“心主神明”

应激性心肌病（SC）是一种受强烈情绪刺激或各种应激因素影响,以短暂性左心室心肌变薄、收缩功能障碍及收缩时左心室球形改变为特征的急性可逆性心肌病。“心主神明”即心主宰情志活动。中医学认为SC的基本病机为情志异常、心神不明、神不驭气、气机紊乱,并提出调养心神以治本、调气畅血以治标的治疗法则。而随着“脑主神明”的提出,“孰主神明”成为各方关注的焦点。自“双心医学”理论提出后,越来越多的现代研究证实了心主神明的科学性。SC作为既是“血脉之疾”又属于“神明之病”的疾病,因其情绪失常导致心脏功能障碍并出现形态学改变的特点,形象地诠释了心神不明对形体心脏的影响,进一步论证了心主神明理论的科学性和重要性。     

基于知识图谱的中医药抗抑郁研究可视化分析

对近20年中医药治疗抑郁症研究文献进行可视化分析,为后续该领域研究提供参考思路和依据。方法：检索中国知网（CNKI）和Web of Science（WoS）数据库,纳入2002年1月1日至2022年12月31日中医药治疗抑郁症研究的相关文献,采用文献计量学软件CiteSpace 6.1.R6及VOSviewer 1.6.18软件对作者、机构、关键词进行可视化分析。结果：共纳入中文文献1555篇,英文文献506篇。该领域发文量呈持续增长趋势,形成了以秦雪梅、王宇红、图娅等为核心的研究团队,发文量最多的机构为北京中医药大学。高频关键词及关键词聚类显示备受关注的干预手段主要以针刺、灸法、逍遥散等为重心,研究内容包括不同干预手段的临床疗效研究和作用机制研究。结论：中医药治疗抑郁症的研究热点集中于作用机制的研究,网络药理学及各种组学技术也在该领域发挥了重要作用,辨证施治、内外兼治是该领域的主要研究方向。

Variations of antioxidant efficiency and presence of endosymbiotic diatoms in the Antarctic porifera Haliclona dancoi

The role of endosymbiotic diatoms as pro-oxidant stressors in porifera has been investigated in the Antarctic sponge Haliclona dancoi in which the presence of diatoms is influenced by marked seasonal variations during the austral summer. Both chlorophaeopigments and frustules were absent in sponge tissues sampled in early November at the beginning of the summer and increased from the mid of December with slightly shifted temporal trends. The efficiency of antioxidant defenses in the sponge showed a marked response to symbionts with clearly enhanced values corresponding to the peak of diatoms.
