OBJECTIVE: To analyze the characteristics of liver pacifying medicinal in the treatment of brain disease to provide scientific evidence in clinical usage on ***: MEDLINE/Pub Med, Google Scholar,and China National Knowledge Infrastructure Database were used as the literature sources. The Scientific name, Latin pharmaceutical name,Chinese name of 7 kinds of liver pacifying medicinal including Gouteng(Ramulus Uncariae Rhynchophyllae cum Uncis), Tianma(Rhizoma Gastrodiae), Juemingzi(Semen Cassiae Obtusifoliae),Quanxie(Scorpio), Wugong(Scolopendra), Jiangcan(Bombyx Batryticatus), and Dilong(Pheretima Aspergillum) were used as the keywords to search the databases for relevant publications up to July2016. Their major compounds were also used as the keywords. The papers were selected based on the pharmacological activities and mechanisms of action related to brain diseases and subsequently,were analyzed and reviewed. We first described the origin, efficacy, and clinical indications of selected medicines, then brain disease specific activities focusing on stroke after the description of the general pharmacological ***: On the basis of the literature of scientific studies and clinical use in traditional medicine, we found and discussed the characteristics of liver pacifying medicinal in stroke treatment. First, liver-pacifying medicinal,or their components, might pass through the blood-brain barrier and act directly on neurons or on the neural network to provide protective effects against brain disease. Second, although it could be used throughout the disease duration,treatment of stroke might be more effective from the subacute up to the convalescent phase than the acute ***: We can suggest that live pacifying medicinal has beneficial pharmacological activities directly or indirectly on neurons in brain disease and is useful for the treatment of stroke from subacute to convalescent phase.

本研究从酸面团中分离酿酒酵母和非酿酒酵母菌,在78株酿酒酵母中筛选出1株产气能力强于商业活性干酵母的菌株,命名为酿酒酵母SQJ20。为提高馒头风味等品质,选择异常威克汉姆酵母GZJ2和德尔布有孢圆酵母SDJ6进行复合发酵馒头制作。当酿酒酵母SQJ20与异常威克汉姆酵母GZJ2以1∶2的比例共发酵时可显著提高馒头的品质。此外,异常威克汉姆酵母GZJ2的添加提高了总蛋白质和游离氨基酸含量(13.69%),其中以甜味脯氨酸(94.69%)、芳香型苯丙氨酸(82.63%)和必需赖氨酸(66.26%)提高的幅度最大。电子鼻和感官评价结果也证实,添加异常威克汉姆酵母GZJ2能有效改善馒头的品质。综上,在不延长发酵时间的情况下,用酿酒酵母SQJ20和异常威克汉姆酵母GZJ2复合发酵能够提高馒头品质,本研究结果可为风味馒头的工业化生产提供参考。

采用复合式膜生物反应器HMBR处理低C/N(3-5)实际生活污水,TN含量17~45 mg/L。基于CCD响应曲面法,考察了溶解氧DO、水力停留时间HRT和污泥龄SRT的单独作用及交互作用,并建立TN去除率数学模型。结果表明,影响因子显著性顺序为HRT>SRT>DO,三者间存在一定的交互作用,但并不显著;数学模型回归性较好,预测最大TN去除率为75%,最佳条件组合为:DO=3.79 mg/L,HRT=8.84 h,SRT=33.62 d,验证实验结果 TN的去除率为73%,与预测值相比偏差仅为3%。采用HMBR处理低C/N生活污水,可以满足《污水综合排放标准》(GB8978-1996)一级标准中对TN≤15 mg/L的限制要求。

功能性状是生物对周围环境响应与适应的直观表现,同时影响一系列的生态系统功能。土壤动物的功能性状可较好地表征和预测环境变化及其所在生态系统的功能变化。综合物种、系统发育及功能性状的多维分析,有助于全面和深入理解土壤动物分布格局、群落构建机制及生态系统功能。本文在阐述土壤动物功能性状常用表征指标和生态学意义的基础上,系统分析了基于功能性状的土壤动物群落响应环境变化及其群落构建过程的相关研究进展,并提出未来在理论上应重点关注生物互作的生态进化过程对土壤动物功能性状的影响,在方法上应注重具有生态学意义的功能性状数据库的建立,还应重视利用功能性状与生态功能的关系指导生态恢复实践,促进土壤生物多样性保护及资源可持续利用。
