书法用笔在山水画中的美学地位

谙熟中国书画艺术的人知道,中国书法与山水画在用笔方面同源异流却又殊途同归。本文从书法与中国山水画所用之工具、“二王”笔法原则来说明书法用笔对山水画的影响,并以美术史中诸位理论家和画家所述“书画同源”的观点来证明书法用笔与山水画笔法之间的联系,从而阐明书法用笔在山水画中的美学地位。

Mechanism of Fuzilizhong decoction alleviating inflammatory damage of rats with non-alcoholic fatty liver disease

AIM To observe the effect of Fuzilizhong decoction on the inflammatory damage of non-alcoholic fatty liver disease （NAFLD） rats and to explore its mechanism. METHODS SPF male SD rats were randomly divided into 6 groups： control group, model group, high dose （20 mg·kg^-1·d^-1）, middle dose （10 mg·kg^-1·d^-1）, low dose （5 mg·kg^-1·d^-1） Fuzilizhong decoction group and Yishanfu （30 mg·kg^-1·d^-1）group, 8 rats in each group. A NAFLD rat modelwas established by intragastric administration of fat emulsion for 4 weeks. Then the drug was given for 4 weeks in each treatment group. HE staining was performed to observe the histopathological changes of the rat liver.The serum levels of interleukin-2（IL-2）, IL-6 and tumor necrosis factor-α（TNF-α） were measured by ELISA. The expression of toll like receptor 4（TLR4） and NF-κB p65 in liver tissues at mRNA and protein levels was determined by RT-qPCR and Western bolt,respectively. RESULTS Compared with control group, the inflammatory damage of liver tissue was more serious, the serum levels of IL-2, IL-6 and TNF-α, the mRNA expression TLR4 and NF-κB p65 in liver tissues were significantly increased in model group（P<0.05）. However, compared with model group, the liver pathological changes in each treatment group were significantly relieved, the serum levels of IL-2, IL-6 and TNF-α, the mRNA expression of TLR4 and NF-κB p65 in liver tissues were significantly reduced（P<0.05）.In addition, the changes of TLR4 and p-NF-κB p65 protein levels in liver tissue were consistent with the changes of TLR4 and NF-κB p65 mRNA. CONCLUSION Fuzilizhong decoction attenuates the inflammatory damages of NAFLD in rats by inhibiting TLR4/NF-κB p65 signaling pathway.     

春大豆抗大豆花叶病毒病鉴定初报

1990年和1991年对127个已定型的春大豆株系的抗大豆花叶病毒病的抗性及产量进行了测定.其中高抗材料有51个,中抗材料19个.在高抗材料中,有7个株系比对照增产10%以上,是很有希望的新品系,有15个材料病指在1.0以下,但产量表现不突出,可作为抗源材料,根据不同地区同一品种抗性差异较大这一结果,抗性自然鉴定圃宜设在大豆病毒病重病区.     

凡纳对虾小触角表面结构的显微观察

应用光学显微镜和扫描电子显微镜观察了凡纳对虾小触角的表面结构。结果发现：小触角上广泛着生着700根以上的羽状刚毛；外鞭片状隆起腹面平均约具280根无顶孔但有细分支的化感刚毛，这类有分支的化感刚毛在其它十足目种类上未见有报道，而且其刚毛数也较其它种类少；内侧附肢前端与柄节上直立的羽状刚毛毛簇顶相接触，推测该结构可能对相邻的复眼具某种作用。     

狂犬病套式PCR检测技术的研究

设计两对引物M1/M2、N1/N2建立起套式PCR,该方法能检测出含0.3LD50狂犬病病毒,比普通PCR的敏感性提高了10000倍,通过27份阳性病料的序列分析,所检测出的病毒全部是狂犬病病毒,具有很强的特异性。表明套式PCR技术具有快速、敏感、特异的特点,可广泛应用于实验室狂犬病的诊断及流行病学调查。     

Bioactive Properties of Peptides and Polysaccharides Derived from Peanut Worms: A Review

Peanut worms (Sipunculids) are unsegmented marine worms that usually inhabit shallow waters. Peanut worms are good source of bioactive compounds including peptides and polysaccharides. Many recent studies have investigated the bioactive properties of peptides and polysaccharides derived from peanut worms in order to enhance their applications in food and pharmaceutical industries. The peptides and polysaccharides isolated from peanut worms have been reported to possess anti-hypertensive, anti-oxidant, immunomodulatory, anti-inflammatory, anti-cancer, anti-hypoxia and wound healing activities through the modulation of various molecular mechanisms. Most researchers used in vitro, cell culture and animal models for the determination of bioactivities of peanut worm derived compounds. However, studies in humans have not been performed considerably. Therefore, it is important to conduct more human studies for better utilization of marine bioactive compounds (peptides and polysaccharides) derived from peanut worms. This review mainly focuses on the bioactive properties of peptides and polysaccharides of peanut worms and their molecular mechanisms.
