Molecular phylogenetic analysis of attached Ulvaceae species and free-floating Enteromorpha from Qingdao coasts in 2007

Based on the sequence data of the nuclear ribosomal DNA internal transcribed spacer(ITS) 1,5.8 S,and ITS 2,the molecular phylogeny was analyzed on Ulvaceae species collected from Qingdao coasts in summer of 2007,including 15 attached Ulva and Enteromorpha samples from 10 locations and 10 free-floating Enteromorpha samples from seven locations.The result supported the monophyly of all free-floating Enteromorpha samples,implying the unialgal composition of the free-floating Enteromorpha,and the attached Ulvaceae species from Qingdao coasts were grouped into other five clades,suggesting that they were not the biogeographic origin of the free-floating Enteromorpha in that season.     

GIS成矿预测的数据驱动与知识驱动分析

在基于GIS的成矿预测方法——证据加权法、神经网络法和模糊逻辑法中，含有数据驱动和知识驱动两种过程。数据驱动和知识驱动各有优点和缺点，不应片面对待。模糊逻辑法既适用于勘探程度低的地区，也适用于勘探程度高的地区，可用于两种目标的成矿预测。

Ulva and Enteromorpha (Ulvaceae, Chlorophyta) from two sides of the Yellow Sea: analysis of nuclear rDNA ITS and plastid rbcL sequence data

Ulvacean green seaweeds are common worldwide; they formed massive green tides in the Yellow Sea in recent years, which caused marine ecological problems as well as a social issue. We investigated two major genera of the Ulvaceae, Ulva and Enteromorpha, and collected the plastid rbcL and nuclear ITS sequences of specimens of the genera in two sides of the Yellow Sea and analyzed them. Phylogenetic trees of rbcL data show the occurrence of five species of Enteromorpha (E. compressa, E. flexuosa, E. intestinalis, E. linza and E. prolifera) and three species of Ulva (U. pertusa, U. rigida and U. ohnoi). However, we found U. ohnoi, which is known as a subtropical to tropical species, at two sites on Jeju Island, Korea. Four ribotypes in partial sequences of 5.8S rDNA and ITS2 from E. compressa were also found. Ribotype network analysis revealed that the common ribotype, occurring in China, Korea and Europe, is connected with ribotypes from Europe and China/Japan. Although samples of the same species were collected from both sides of the Yellow Sea, intraspecific genetic polymorphism of each species was low among samples collected worldwide.

基于测井信息的煤焦油产率预测方法研究

低阶煤低温干馏生成的煤焦油是重要有机化工原料,焦油加工精炼已作为近代煤化工的一个重要分支．为了建立煤焦油产率预测技术方法,服务于煤焦油地质储量评价,本文在文献调研基础上,遵循“地质约束测井、岩心刻度测井”原则,开展研究区煤焦油产率敏感因素分析,厘定与煤焦油产率相关地质参数,利用统计分析方法确定与煤焦油产率敏感的测井信息;利用多元回归分析方法和神经网络技术首次开展了煤焦油产率测井预测方法探索．研究表明,低阶煤的焦油产率普遍高于中高阶煤,对煤焦油产率敏感的地质因素主要有煤化程度（镜质体反射率）、温度和压力、煤质灰分与固定碳含量;对煤焦油产率敏感的测井信息主要包括补偿密度、自然伽马、电阻率等;分区开展多元回归建模可实现利用密度、自然伽马和电阻率测井响应对煤焦油产率预测;将神经网络技术引入煤焦油产率分区预测可行．研究成果对做好煤焦油地质储量评价具有重要的技术支撑作用．     

益气补肾汤治疗原发性骨质疏松症65例临床观察

目的：观察益气补肾汤对原发性骨质疏松症的治疗效果。方法：选取原发性骨质症疏松患者130例，采用随机数字表法将其分为治疗组与对照组，每组各65例。对照组采用西药常规治疗，治疗组在此基础上自拟益气补肾汤治疗，2组均连续治疗6个月。观察比较2组的综合疗效、骨密度及用药安全性。结果：总有效率治疗组为90.77%（59/65），对照组为73.85%（48/65），2组比较，差异有统计学意义（P＜0.05）。2组腰椎L2～4、髋部骨密度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）。结论：益气补肾汤治疗原发性骨质疏松症，可改善病情，提高骨密度，疗效显著，安全可靠。
