添加松针粉对肉鸡营养物质代谢率的影响

选用18日龄肉鸡80羽,随机分为4组,分别为组Ⅰ、组Ⅱ、组Ⅲ、组Ⅳ,其中组Ⅰ、组Ⅱ、组Ⅲ为试验组,组Ⅳ为对照组。每组5个重复,每个重复4羽(♀)。采用单因子随机分组设计,共设4个处理,组Ⅰ为基础饲料+1%松针粉,组Ⅱ为基础饲料+3%松针粉,组Ⅲ为基础饲料+5%松针粉,对照组为基础饲料+抗生素。研究结果表明,干物质表观代谢率组Ⅰ、组Ⅱ与对照组之间无显著性显著(P>0.05),但组Ⅲ干物质表观代谢率显著低于对照组(P<0.05),5%松针粉组干物质代谢率比对照组低5.46%,其余各组间无显著性差异(P>0.05);粗蛋白质日摄入量及日排出量各组间均无显著性差异(P>0.05);粗蛋白质表观代谢率组Ⅰ、组Ⅱ、组Ⅲ显著高于对照组(P<0.05),组Ⅰ、组Ⅱ、组Ⅲ分别比对照组提高了18.34%、23.44%、27.13%;粗脂肪日摄入量组Ⅲ显著高于组Ⅰ和对照组(P<0.05),试验组之间无显著性差异(P<0.05);粗脂肪日排出量组Ⅲ显著高于组Ⅰ、组Ⅱ及对照组(P<0.05),其余各组间无显著性差异(P>0.05);粗脂肪的表观代谢率组Ⅰ、组Ⅱ显著高于对照组(P<0.05),其余各组间无显著性差异(P>0.05),粗脂肪的表观代谢率组Ⅰ、组Ⅱ、组Ⅲ分别比对照组提高了6.86%、9.43%、5.05%;磷的日摄入量、日排出量、表观代谢率各组间无显著性差异(P>0.05)。

油松人工林养分循环的研究 Ⅱ.油松人工林养分元素的动态特性

本文以华北中山地区的油松人工林分作为研究对象,在林分各组分营养元素含量静态分布研究的基础上,对林分养分元素的动态特性进行了分析讨论,结果表明:(1)在一年中林木枝、叶、磷、钾、镁的含量因季节而异,其变化规律与林木的生长节律有关;(2)针叶凋落的年动态及其养分含量的变化,在一定程度上也受林木生长节律影响;(3)林地枯落物平均年干重损失率为14％,与其它林种相比,该立地上的油松林分林地枯落物分解较慢。     

Provenance variation in Christmas tree characteristics in subalpine fir (Abies lasiocarpa) planted in Denmark and Iceland

A field test with 26 provenances of subalpine fir and corkbark fir was established at three sites in Denmark and one site in Iceland in 1999. Survival, growth and Christmas tree quality were assessed after 10 growing seasons in Denmark and 12 in Iceland. Provenances showed significant differences for all measured traits. The western-most subalpine fir provenances from Washington state and British Columbia showed the overall best results in Denmark with the highest survival (after 15 years), fastest growth in height and highest Christmas tree quality and profitability as well as both good postharvest needle retention and high resistance to pests. The corkbark fir provenances also showed high Christmas tree quality and the lowest frequency of fork formation, but corkbark fir provenances also exhibited the poorest postharvest needle retention. In Iceland, the corkbark fir provenances generally showed the highest survival rate and Christmas tree quality. The White River provenance from British Columbia is recommended for use in Denmark. The Mount Taylor provenance from the Cibola National Forest in New Mexico is recommended for use in Iceland.

针刺治疗脑卒中后吞咽障碍临床疗效的系统评价

目的 采用Meta分析评价针刺与其他常规方法治疗脑卒中后吞咽障碍的临床疗效。方法 计算机检索建库至2018年12月中国期刊全文数据库、万方数据库、维普数据库、中国生物医学文献数据库、PubMed数据库中针刺治疗脑卒中后吞咽障碍的临床随机对照研究,并辅以人工检索湖南中医药大学图书馆的过刊资料库,制定文献纳入及排除标准,提取资料,评价纳入文献的质量,利用Revman 5.3软件进行Meta分析。结果 共纳入28篇文献,病例数2 557例。Meta分析结果提示治疗组对吞咽障碍的总有效率优于对照组（Z=12.51,P<0.000 01）,且治疗组在改善MBI评分、SWAL-QOL评分方面优于对照组,差异有统计学意义（P<0.05）;但治疗组在改善患者肺部感染情况上无明显优势,与治疗组差异无统计学意义（P>0.05）。结论 针刺治疗脑卒中后吞咽障碍可提高现代康复治疗的临床疗效,有助于改善患者日常生活活动能力和生活质量,但由于本研究纳入的文献数量和质量存在不足,仍需进一步研究予以证实。

What is your diagnosis? Vertebral mass in a dog

Abstract: A 1‐year‐old, castrated male, mixed‐breed dog was presented for sporadic episodes of kyphosis, tremors, and vocalizing. On neurologic examination, the lesion was localized to spinal cord segments T3–L3. Magnetic resonance imaging of the spine showed an expansile mass occupying most of the ventral aspect of the spinous process of T6. Fine‐needle aspirates of the mass were examined cytologically. A moderately cellular population of pleomorphic spindle cells and abundant mucinous matrix were observed. The cytologic diagnosis was spindle cell neoplasia, with myxosarcoma and fibrosarcoma as the primary differential diagnoses. The dog was euthanized. Histopathologic evaluation of the mass and surrounding tissue confirmed a low‐grade spindle cell sarcoma, with severe compressive myelopathy and mild neutrophilic inflammation. The neoplastic cells stained positive for mucopolysaccharides with Alcian blue, resulting in a final diagnosis of low‐grade (grade 1) myxosarcoma. Fine‐needle aspiration was useful in making a preliminary diagnosis of myxosarcoma in this case. Myxosarcoma should be included in the differential diagnosis for a vertebral mass in a young dog.
