五行学说对中医学有深刻的影响,体现了传统医学重视联系、整体的特点,但五行学说本身有局限性,不能全面地反映事物间的普遍联系。中医以五脏配属五行,吸收了五行学说的精华;又根据脏腑学说的理论,在实践中超越了五行的限制。因此,中医的理论可名为“五脏相关学说”。在中医理论现代化中,可以将五脏之间的影响归纳为促进、抑制和协同3种关系,从多种角度来阐明中医的整体性与联系观。

IN VITRO ACTIVITY OF EXTRACTS OF FIVE MEDICINAL PLANT SPECIES ON PLANT PATHOGENIC FUNGI
《农业科学与工程前沿(英文)》 2021年 第8卷 第4期 页码 635-644 doi: 10.15302/J-FASE -2020343
The antifungal effectiveness of extracts of five medicinal plant species was determined. The inhibitory activity of extracts of Eucalyptus tereticornis, Xanthium sibiricum, Artemisia argyi, Tupistra chinensis and Pyrola calliantha were evaluated against the mycelial growth of the plant pathogenic fungi Aspergillus niger, Botrytis cinerea, Penicillium digitatum, P. expansum, P. italicumand Rhizopus stolonifer. All plant extracts were prepared at 60°C using solvents (either water, 50% ethanol (v/v), 95% ethanol (v/v), ethyl acetate or petroleum ether). Fungicidal effects of all plants tested were confirmed. Different extracts from the same plant species gave different degrees of inhibition. All aqueous extracts had weak or no activity on all fungi tested. Ethyl acetate and 95% ethanol extracts from T. chinensis rhizomes gave greater inhibition and a broader spectrum inhibition than the other extracts. T. chinensis may have potential as a new natural fungicide and may be used for the preservation of agricultural and forestry products such as fruits and vegetables.

Paratesticular fibrous pseudotumor: a report of five cases and literature review
null

Paratesticular fibrous pseudotumor is a rare benign tumor that originates from intrascrotal tissue, such as tunica vaginalis, epididymis, or spermatic cord. Five cases of fibrous pseudotumor in our hospital were reviewed retrospectively, and the clinical manifestations were analyzed. Three cases of unilateral nodules, comprising one case located in the tunica vaginalis and two cases located in the epididymis, underwent local excision of the unilateral nodule. Two cases of diffuse incrassation in the tunica vaginalis underwent right radical orchiectomy. Postoperative pathological examination showed that all were fibrous pseudotumors. An average follow-up of 26 months showed uneventful results without recurrence for all patients. Fibrous pseudotumor is not a neoplasm but a reactive fibrous inflammatory hyperplasia. Definitive diagnosis requires pathological examination. Radical orchiectomy should be avoided when possible, and local excision should be performed because of the lack of obvious evidence of potential malignancy.

“养殖业十三五规划战略研究”项目组
《中国工程科学》 2016年 第18卷 第1期 页码 17-21 doi: 10.15302/J-SSCAE-2016.01.003
“十三五”期间乃至未来一段时间内,我国养殖产品需求仍呈刚性增长,但是养殖业面临资源短缺日趋严重、环境制约日益加剧等不利局面,同时面临国际竞争对国内产业冲击加剧等新的形势,未来我国养殖业必须走可持续发展道路。本文基于对我国养殖业的发展现状、可持续发展所面临的挑战,形成对我国养殖业可持续发展形势的基本判断,针对“十三五”,凝练了养殖业可持续发展的战略目标、基本原则和战略重点,并提出了“进一步明确养殖业在现代农业中的战略主导地位”“合理利用国际市场保障我国食物安全”“加快启动和实施一批养殖科技重点研发计划”等重大建议,为我国养殖业加快发展方式转变、实现现代化提供理论支撑。

本文以五品联动理论为研究背景,考虑到矿山工程中地质工程、采矿工程、配矿工程、选矿工程和冶炼工程5 个工程是相互联系的串联耦合工程,是矿山企业活动的主体,而与其相对应的地质品位、采出品位、入选品位、精矿品位和入炉品位对于矿山整体经济效益起到关键的控制作用。本文运用并拓展了“质量守恒”原理,利用“矿量守恒”和“金属量守恒”建立了品位经济效益模型,提出了五品联动品位—效益活跃指数,通过实例计算与分析,获得了某铁矿的品位优化数值,为进一步研究矿山企业工程管理模式奠定了基础。
