海南岛西海岸红树林软体动物多样性

为了掌握海南岛西海岸红树林软体动物多样性状况,本文于2015–2016年对海南岛西海岸6个主要红树林分布区软体动物的种类组成、物种多样性和群落结构的时空变化进行了研究。共采集到软体动物57科201种,主要优势种有珠带拟蟹守螺(Cerithidea cingulata)、绯拟沼螺(Assiminea latericea)、圆胖樱蛤(Pinguitellina cycladiformis)和斜肋齿蜷(Sermyla riqueti)等。年平均密度与平均生物量分别为324.13 ind./m~2和142.88 gm~2,物种数、密度和生物量均高于北部湾沿岸的其他红树林。海南岛西海岸各红树林软体动物的密度和生物量均未呈现明显的季节变化,软体动物密度存在空间上的显著差异。聚类分析结果显示,在盐度、土壤结构和红树林群落存在差异的不同红树林,软体动物种类组成相似度低。多因子AZTI海洋生物指数(M-AMBI)结果表明海南岛西海岸红树林软体动物群落未受明显扰动,生态环境质量介于一般和优良之间,但仍受到人类活动与外来植物入侵威胁,因其在候鸟迁徙中的重要作用,亟需加强管理与保护。国家自然科学基金(31670490;31600436

Selection of salt-tolerant plants for high-salinity wastewater treatment by constructed wetlands

人工湿地作为一种新兴污水处理工艺,具有高效、低成本等优点,但因缺乏能够在高盐环境中生存的湿地植物,因此应用于高盐污水处理还存在诸多难题.基于对我; 国南方海岸及海岛的大量野外调查及文献调研,依据生理指标、形态指标、经济成本和应用潜力等,筛选出耐盐、耐水湿、耐污、净化能力强、生长快、生物量大、; 栽培简单、分布广泛并具有景观效果的南方滨海耐盐植物23种,进一步对每一种植物的耐盐能力进行分级,其中耐盐能力最强的种类为扁秆荆三棱(Bolbos; choenus planiculmis)、海雀稗(Paspalum vaginatum)、川蔓藻(Ruppia; maritima)、海马齿(Sesuvium portulacastrum)和盐地碱蓬(Suaeda; salsa).本研究结果可为人工湿地的构建提供更多植物种类选择,并促进人工湿地可持续的净化功能与景观功能的有机结合.Currently, efficient technology for combining wastewater treatment and; water reuse is urgently required to cope with water shortage and; increased high-salinity wastewater. As an emerging technique for; wastewater treatment, constructed wetlands have the advantages of high; efficiency, low cost, and so on. However, owing to the scarcity of; wetland plants that can survive in environments with high salt; concentrations, constructed wetlands encounter huge obstacles in the; treatment of highsalinity wastewater. In this study, based on extensive; field investigations and literature review, 23 salt-tolerant coastal; plants with characteristics of salt tolerance, waterlogging resistance,; pollution tolerance, high purification ability, rapid growth, large; biomass, simple cultivation, wide distribution and landscape effect were; selected, and salt tolerance of each species was rated. The species with; the highest salt tolerance were Bolboschoenus planiculmis, Paspalum; vaginatum, Ruppia maritima, Sesuvium portulacastrum, and Suaeda salsa.; The result can provide more choices of plants for constructing; artificial wetlands, and contribute to integration of sustainable; purification function and landscape service.国家重点研发计划; 海洋公益性行业专项子课

Autophagy Inhibition by Chloroquine Sensitizes Cervical Cancer SiHa Cells to CPT Treatment

自噬诱导是肿瘤细胞对化疗药物抵抗性的原因之一,该研究探讨溶酶体抑制剂氯喹对喜树碱(camptothecin,CPT)诱导的宫颈癌细胞Si Ha死亡的增敏效果。CPT和/或氯喹处理宫颈癌Si Ha细胞,MTT法检测细胞增殖,DAPI和TUNEL染色观察细胞凋亡,Western blot和免疫荧光检测自噬及凋亡相关蛋白。结果发现,CPT处理后,Si Ha细胞MAP1LC3B荧光点和LC3II(microtubuleassociated protein light chain 3II)蛋白水平增加,p62荧光点和蛋白质水平则减少;而采用氯喹特异抑制自噬后,可明显提高CPT诱导的细胞凋亡、caspase-9的激活和PARP(poly ADP-ribose polymerase)的切割,而全长caspase-2水平显著下降。以上结果提示,氯喹可通过抑制细胞自噬而增强宫颈癌细胞株Si Ha对CPT诱导细胞凋亡的敏感性。The autophagy induction is one of the reasons for the resistance of tumor cells to chemotherapy drugs. In this study, the enhanced sensitivity of cervical cancer Si Ha cells to camptothecin(CPT)-induced cell death by chloroquine(a lysosome inhibitor) was investigated. The cell viability was detected by MTT assay, meanwhile, apoptosis was observed by DAPI and TUNEL, autophagy related proteins and apoptosis proteins were analyzed by immunofluorescence(IF) staining and Western blot in Si Ha cells after CPT treatment alone or combined with chloroquine. The results found that in Si Ha cells with CPT treatment the autophagy related protein LC3 foci and microtubule-associated protein light chain 3II(LC3II) protein level was increased, but p62 foci and protein level was decreased. When autophagy was inhibited by chloroquine, the CPT-induced apoptosis was obviously enhanced, and caspase-9 was activated and PARP was cleaved, but full length caspase-2 was decreased. Taken together, these results indicated that the inhibition of autophagy by chloroquine could sensitize cervical cancer Si Ha cells to CPT inducing cell apoptosis.山西省自然科学基金(批准号:2014021037-9);; 山西医科大学汾阳学院博士启动基金(批准号:1301);山西医科大学汾阳学院科研项目基金(批准号:1422)资助的课题~
