Characterization of Iron Grains near the P/T Boundary in the Meishan Section of China

The Meishan section of China has been confirmed as the ＂Global Stratotype Section and Point＂ of the P/T boundary. In the section, the authors found several types of iron grains, including pyrite, pure iron grains and goethite. From the research of macro minerals, it is easy to find that the grains rich in iron appear from the bottom of the event layer of the section. In other words, it is probably residue of the geochemical catastrophe of that time. Therefore, it is important to trace the source of these iron grains and their relationships, which probably provides evidence for volcanic eruption or impact-volcanoes and has directive significance to the crisis during the P/T transitional period. Through the study of the characterization and relationships of these iron grains, the authors make a preliminary discussion on the P/T mass extinction.     

A Study of Chromium Adsorption on Natural Goethite Biomineralized with Iron Bacteria

Goethite, especially biogenic goethite, has high specific surface area and great capacity for the adsorption of many contaminants including metal ions and organic chelates. Chromium is a redox actively toxic metal ion that exists as either Cr^Ⅲ or Cr^Ⅵ in nature, and as such it is essential to understand its behavior of adsorption on natural goethite mineralized by iron bacteria, as Gallionella and Leptothrix in water body. The adsorption of Cr^3＋ and Cr^Ⅵ on naturally biomineralized goethite is studied in this paper. The results show that both Langmuir and Freundlich adsorption isothermal models are able to accurately describe the adsorption of these two ions. Investigation of SEM/EDS, TEM/EDS indicates that the two ions do not adsorb homogeneously on goethite owing to the different microstructures of goethite, and that the microspherical goethite has a greater adsorption capacity for chromium ions than the helical one. XPS data show that redox reaction of chromium on the surface of biomineralized goethite takes place in the adsorption of both Cr^3＋ and Cr^Ⅵ. The CrvI adsorbed on biogoethite is much easier to transform into CrIII than the oxidization of Cr^Ⅲ on the bio-goethite.

西药联合水筋针治疗痛风性关节炎30例临床观察

目的：观察西药联合水筋针治疗痛风性关节炎的临床疗效。方法：将60例痛风性关节炎患者随机分为治疗组和对照组,每组各30例。对照组给予秋水仙碱片和依托考昔片治疗,治疗组在对照组治疗基础上联合水筋针治疗,10d为1个疗程。观察各组血尿酸（UA）、肌酐（Scr）、尿素氮（BUN）水平,主要症状体征（关节疼痛、肿胀、活动、皮肤潮红）、综合疗效及不良反应。结果：总有效率治疗组为100.00%（30/30）,对照组为80.00%（24/30）,2组比较,差异有统计学意义（P＜0.05）。治疗组UA、Scr、BUN治疗前后组内比较及治疗后组间比较,差异均有统计学意义（P＜0.05）。治疗组关节疼痛、肿胀、活动、皮肤潮红改善情况优于对照组（P<0.05）。治疗组不良反应发生率较对照组低（P<0.05）。结论：西药联合水筋针治疗痛风性关节炎能控制症状体征,疗效持久,药物不良反应低。
