浅析茶壶画艺术之美——以边寿民、薛怀、陈鸿寿、吴昌硕、齐白石作品为例

古语说:“水为茶之母,壶为茶之父”。茶壶是茶具的主角之一,自从文艺界人士参与到造壶活动中后,他们以抽象的艺术语言,展现出了别具一格的艺术之美,赋予茶具以蓬勃的生命。本文以清代至现代五位著名画家为例,浅析他们所作茶壶画的艺术之美。

女诗人薛涛与望江楼公园

以纪念女性为主的园林是中国历史园林的特殊类型,理清其营建的动因和经验,是传承中国园林文化的重要补充。纪念唐代女诗人薛涛的望江楼公园,其兴建、发展、造景等方面与薛涛的人生经历、个性品行紧密结合。基于历史文献梳理和园林空间分析,剖析了望江楼公园的发展变迁历程,归纳了针对薛涛的园林景观的纪念性造景手法,从遗迹、植物、建筑、活动等方面分析了女诗人薛涛与望江楼公园之间相辅相成的关系。     

Influence of Nao Xue Kang tablet on dynamic expression of PAR-1 after acute intracerebral hemorrhage in rats

AIM: To study the dynamic expression of protease-activated receptors-1 (PAR-1) after intracerebral hemorrhage (ICH) and the influence of Nao Xue Kang Tablet (NXKT) on it's expression. METHODS: 72 Wistar rats were divided into normal group, ICH model groups (ICH, 6 h, 24 h, 3 d, 7 d), Nao Xue Kang groups (NXKT, 6 h, 24 h, 3 d,7 d). ICH models were produced with the induction of collagenase typeⅦ-S, except normal group. Immunohistochemical method was used to detect PAR-1 protein and RT-PCR technique was used to detect PAR-1 mRNA in brain tissues around the haematoma at different time points of different groups. RESULTS: PAR-1 protein and mRNA were mildly positive in normal group. In ICH model groups, intensity of PAR-1 expression started to increase at 6 h, and further increased at 24 h. PAR-1 expression reached the peak at 3 d and began to descend. At 7 d the decent was obvious. At 6 h, 24 h, 3 d, and 7 d time points, the PAR-1 protein positive cell number and PAR-1 mRNA absorbance ratio in ICH model and NXKT groups were significantly higher than those in normal group (P<0.05 or P<0.01). The PAR-1 protein positive cell number and PAR-1 mRNA absorbance ratio in NXKT group were significantly lower than in ICH model group (P<0.05 or P<0.01). CONCLUSION: After ICH, PAR-1 is continuously activated because of the stimulation of thrombin. Action of thrombin after ICH may be mediated by PAR-1; NXKT may inhibit the activation of PAR-1, so the praxiology is improved. This may be one of the main mechanisms that NXKT could facilitate the recovery of nervous function.

桐油转化生物柴油的研究

为了考察桐油制备生物柴油的可行性,分析了桐油的脂肪酸成分,研究了桐油转化生物柴油的工艺条件,并测定了桐油生物柴油的主要性能指标。结果表明,桐油的平均相对分子质量为927.32,其主要成分为含有18个碳的不饱和脂肪酸,其中α-桐酸是其脂肪酸的主要成分(75.033%)。酯交换法制备桐油生物柴油的最佳工艺条件为:甲醇与桐油的摩尔比6∶1,催化剂用量为桐油质量的1.0%,反应温度30℃,反应时间20 min,平均转化率为82.8%。在此最佳条件下制备的桐油生物柴油的主要性能指标,除运动粘度、酸值较高外,基本符合0#矿物柴油标准。     

同羊春毛理化特性的研究

研究结果表明,同羊春毛纤维类型数量比例较30年前有所改善.比秋毛弯曲明显整齐,弯曲率大,光泽好,摩擦效应大;17种氨基酸含量及总量也多于秋毛;伸度和强度的集中性及含硫量差于秋毛;表面结构也不及秋毛好,特别是含硫量还低于羊毛一般水平.     

高三尖杉酯碱、血栓通与地塞米松联合对翼状胬肉成纤维细胞的抑制效果

用中药高三尖杉酯碱（Ｈｏｍｏｈａｒｒｉｎｇｔｏｎｉｎｅ）及血栓通（ＸｕｅＳｈｕａｎＴｏｎｇ）与地塞米松（Ｄｅｘａｍｅｔｈａｓｏｎｅ）联合应用，对体外培养的人翼状胬肉成纤维细胞抑制的结果表明：前两药的给药浓度分别在１０－６Ｍ／Ｌ及３ｇ／Ｌ时，抑制率为５０．４％及６４．３％，均有明显的抑制作用及相应的细胞形态学改变。当高三尖杉酯碱给药浓度为１０－４Ｍ／Ｌ时．其细胞增殖抑制率达９１．８％，镜下基本见不到正常细胞。而当两药分别与地塞米松联合应用时，呈现比单一药物应用时的药量减少而药效增强。

CLINICAL,DIAGNOSTIC, AND PATHOLOGICAL FEATURES OF 2 CASES OF METASTATIC IRIDOPHOROMA IN A VEILED CHAMELEON (CHAMAELEO CALYPTRATUS) AND A RED-BARRED DRAGON (CTENOPHORUS VADNAPPA)

Iridophores are iridescent cutaneous pigment cells found in reptiles, fish, and amphibians. Neoplasms of iridophores are rarely reported, and little is known about their behaviour, metastatic potential, and prognostic indicators. This paper reports details of the clinical course and pathological findings of metastatic iridophoroma in a veiled chameleon (Chamaeleo calyptratus) and red-barred dragon (Ctenophorus vadnappa). The veiled chameleon presented with a subcutaneous mass on the right lateral elbow and was diagnosed as an iridophoroma on fine needle aspiration. It was otherwise clinically normal. Within 35 days of excision, multiple secondary skin masses developed which were often non-pigmented and required microscopic examination to identify them as iridophoroma metastases. There were in total 54 days between the first detection of the primary mass and end stage, extensive cutaneous and visceral metastatic disease, and there had been no detectable primary mass during routine clinical examination 128 days prior to death. The red-barred dragon presented with a white sub-mandibular mass. While undergoing an excisional biopsy the animal expired, post-mortem examination revealed a cutaneous malignant iridophoroma with tumour cell clusters seen in pulmonary arterial vessels, suggesting that surgical handling of iridophoroma could precipitate the release of circulating tumour cell clusters. This is the first iridophoroma described in a red-barred dragon and the second report of a malignant iridophoroma in a veiled chameleon. Timely detection and careful excision of lizard iridophoroma may be an important factor in clinical outcome.
