《淮南子》的和谐教育思想及现实意义

《淮南子》对人的发展方面提出了许多宝贵的教育思想,提出“因性而教”的教育原则,实现“用之于其所适”的自我价值;特别重视环境教育的社会性内涵对人的影响,提高人的主体能动性;《淮南子》提出“积极有为的人生观”,把人所具有的自然属性与社会属性整合起来：自动地适应环境与在实践中实现自我存在。最终构建一个“天、地、人”多层次统一发展的“和谐”之人。

3个产地板蓝根多糖作用的比较研究

通过小鼠吞噬试验、脾淋巴细胞增殖试验和最低抑菌与最低杀菌浓度的检测,对不同产地板蓝根多糖功能进行比较研究。结果表明,3个产地板蓝根多糖均使小鼠吞噬能力增强,并协同促进淋巴细胞增殖,具有一定的杀菌和抑菌效果。     

伪狂犬病毒GDSH株的分离鉴定及gE基因的序列分析

从广东四会某猪场分离到一株疑为猪伪狂犬病病毒(PRV)的病毒,病毒在猪肾细胞上出现细胞变圆、拉网、融合等典型病变,并具有细胞泛嗜性特点。在MDCK细胞上测得其TCID50值为10-8/0.1mL,能被伪狂犬病病毒标准阳性血清中和。将0.1mL病毒液接种小鼠后发生奇痒并麻痹致死,接种猪3天后发病,7天死亡,从攻毒病死猪的脑组织病理切片上观察到典型的病毒性脑膜脑炎及血管套现象。通过PCR扩增到PRVgD基因,由此进一步证明所分离病毒为猪伪狂犬病毒,并命名为GDSH株。根据GenBank中发表的序列,设计一对扩增PRVgE基因的特异性引物,建立可以区分PRV野毒株与疫苗株的PCR诊断方法。以此方法对病毒的细胞培养液进行检测,结果证实所分毒株为PRV野毒株,经克隆测序后与GenBank收录的其它PRVgE基因序列进行比较,发现所测毒株的核苷酸序列与其它PRV毒株的同源性介于98.3%～99.9%之间,其中与PRVEa株的亲缘关系最近为99.9%。     

Survey and Analysis of Common Diseases of Laboratory Monkeys in Kunming Area

Survey and analysis of common diseases of laboratory monkeys are great significance to understand disease epidemiology, and formulate a set of scientific and reasonable measures for prevention and control disease, to improve the quantity and quality of laboratory monkeys, to ensure the accuracy of the animal experiment results. Through the investigation of the sick and dead animals of a large-scale laboratory monkeys breeding facility in Kunming area in 2014, the animals were classified depends on the main diseases, and the diseases were classified according to adult and juvenile animals, data were analyzed by Excel Office 2010 software. The results showed the common diseases of laboratory monkeys included the digestive system, respiratory system, trauma, reproductive system, and locomotor system disease, which were 47.45%, 13.06%, 12.10%, 11.46% and 8.92% separately; Common diseases included diarrhoea, soft tissue injuries, abortion, lobar pneumonia, dysentery, arthritis, intestinal pneumatosis, chronic colitis, and extreme bad nutrition, the ratio were 18.47%, 11.15%, 8.91%, 8.28%, 8.28%, 7.96%, 5.10%, 5.10% and 5.09% separately. Comprehensive analysis of common diseases and disease occurrence causes of the laboratory monkeys, suggesting that providing better quality laboratory monkeys for scientific research only by constantly improving the scientific breeding management level, constantly strengthening veterinary capacity, mastering the theoretical knowledge and scientific diagnosis method.

The role of lectures in veterinary education

OBJECTIVE: To study the role of lectures from the perspective of staff and students involved in the veterinary course at The University of Queensland. METHODS: The Nominal Group Technique of Delbecq et al, which provides the maximum opportunity for group members to put forward points, was used to help develop a questionnaire which was completed by 351 students (a response rate of 84%) and 35 staff (76%) from the five years of the veterinary course, and was analysed using the SAS System for Windows. RESULTS: Almost all the staff and students agreed that lectures should fulfil many roles including stimulating and motivating students and encouraging them to think, as well as presenting ideas and concepts and an indication of the structure and relevance of the material. They should provide a guide for effective deep learning, but not encourage rote (or superficial) learning. A smaller percentage of staff and even fewer students agreed that lectures did fulfil these roles, especially those directed at encouraging students to look beyond simple memorisation of facts. The perceived disparity between reality and the ideal was greater amongst the older, clinical students than amongst their more junior colleagues. CONCLUSIONS: The focus of attention in lectures needs to change from the superficial, rote learning of information to deep, active learning directed at using information to solve problems that are perceived by the students to be relevant. If done in a stimulating and interesting way, this should develop skills in reasoning and critical analysis as well as providing a framework for storage and recall. It should also increase the motivation towards learning both during the veterinary course, and over the professional lifetime. Furthermore, the place of the lecture in veterinary education needs to be reassessed regularly in the face of newly-emerging educational technology.     

蝗虫痘病毒对黄胫小车蝗生长发育和产卵力的影响

试验观察结果表明,蝗虫痘病毒除对黄胫小车蝗有显著致死作用外,使感病寄主在接种13～33d后,食量比对照减少28.73%～70.40 %导致生长发育缓慢,接种后13～18d,对照组生长率为36.3mg/d,而处理组则分别为14.9、14.5和9.6mg/d,仅为对照的1/4～1/2。寄主羽化极不整齐,对照组整个历期只有5d,而处理组则为16～46d,随着接种剂量的加大,这种“拖延”趋势越发明显。寄主产卵量明显降低,甚至根本不能产卵。处理组寄主“畸形”和“自相残杀”的情况也较对照组严重。
