人白血病细胞系KG1a中P2X7受体的表达和功能研究

用半定量RT-PCR和流式细胞术，研究了白血病细胞系KG1a中P2X7受体在基因和蛋白水平的表达。用荧光分光光度计，测定了用激动剂三磷酸腺苷（ATP）和苯甲酰苯甲酸ATP（BzATP）刺激前后细胞内钙离子浓度的变化，证明P2X7受体的功能。结果表明：KG1a细胞表达P2X7受体，且在激动剂的刺激下能引起KG1a细胞通过P2X7受体的胞外钙内流；去除胞外钙离子时，激动剂不能引起胞内钙浓度的升高；提示KG1a细胞表达P2X7受体的基因和功能蛋白，激活该受体引起胞外钙离子的内流。     

《九歌》的体式与原始“倚声填词”臆测

文章将《九歌》与《九章》的体式进行对比，发现二者篇幅一短一长，体式一复杂多变一简单，其中“二湘”与“二司命”在篇幅、句式及押韵换韵等方面都相同或相似。因此，推测《九歌》既是据楚民间“九歌”的改创之词，又是倚“九歌”曲调而填写的歌词，即屈原《九歌》是据“九歌”的九支曲调填写的十一首诗歌；进而论证“倚声填词”之法并非起于唐宋或六朝，而是古已有之。

柳宗元骚体文中的讽谕与教化思想刍议

柳宗元是杰出的古文运动倡导者，更是唐代辞赋大家，其于贬谪时期所创作的十篇骚体文极具特色，本文即是以这十篇骚体文为研究对象，先探讨柳宗元政治上的遭遇以作为深入骚体文内容的基石，继而深入地耙梳与探讨文体流变的现象，以呈现柳宗元发扬屈骚融铸而成骚体文的讽谕与教化精神。柳宗元骚体文的写作方法借物讽刺、借事讽刺；其骚体文的艺术特色与蕴涵的思想包括：命题之善；篇篇有警语；以散文作序，骚为正文；精于描写，形象生动鲜明；讽刺隐微，深寓教化。从十篇骚体文的内涵、作法、艺术特色、蕴涵的思想及其对後世的影响等相关问题进行分析，藉以了解柳宗元骚体文的创发之功；其“穷形尽相”、“结合散韵”、“善用隐喻”的书写风格，不仅体现了“导扬讽谕”的文学观也在辞赋史上获得了杰出的成就。     

亦真亦幻的佛国世界——浅议库木吐拉的汉风壁画

库木吐拉石窟位于库车县库木吐拉村,是新疆汉风壁画遗存最多的一处石窟。库木吐拉的汉风洞窟已可初步确认的达20多个,尚有许多因风沙和水渍的毁坏已无法统计。本文选择其中最具代表性的11、14、16、73号洞窟等,就其风格技法作初步的探讨。     

王昌龄五古与七绝风格之比较及其创作心态试析

盛唐时期著名诗人王昌龄的诗歌创作成就 ,主要在五古和七绝两种体裁上。其五古显得严正肃然 ,高古劲健 ,饶有风骨 ;其七绝却呈现出华美婉丽、精工雕琢的诗风。前者反映了他对以陈子昂为代表的文学复古思潮的响应 ,后者则反映了他对文学复古思潮中矫枉过正的偏激有所修正的态度。将他在这两种诗体上表现出来的不同风格 ,与他的诗论结合起来考察 ,还可看出他以五古经营世务和以七绝遣兴抒怀的不同创作心态     

Semantic categorization of digital home photo using photographic region templates

In this paper, a semantic categorization method in generic home photos is proposed. In recent years, the semantic categorization of image has been a challenge due to the proliferation of digital home photos. Our approach is to detect semantically meaningful concepts contained in a photo. The proposed method incorporates an intermediate level of concepts, called local concept, so that it catches well semantic meaning of local regions of image as bridging the semantic gap of the low-level features and high-level category concepts. To detect the local concepts from the home photo, region segmentation by photographic region template and concept merging is also proposed. The efficacy of the proposed semantic categorization method was demonstrated with 3828 general home photos. The experiment results showed the proposed categorization method would be useful to detect multiple semantic meaning of the home photos.     

An extended chemical analysis of gallstone

Chemical composition of gall stones is essential for aetiopathogensis of gallstone disease. We have reported quantitative chemical analysis of total cholesterol bilirubin, calcium, iron and inorganic phosphate in 120 gallstones from haryana. To extend this chemical analysis of gall stones by studying more cases and by analyzing more chemical constituents. A quantitative chemical analysis of total cholesterol, total bilirubin, fatty acids, triglycerides, phospholipids, bile acids, soluble proteins, sodium potassium, magnesium, copper, oxalate and chlorides of biliary calculi (52 cholesterol, 76 mixed and 72 pigment) retrieved from surgical operation of 200 patients from Haryana state was carried out. Total cholesterol as the major component and total bilirubin, phospholipids, triglycerides, bile acids, fatty acids (esterified), soluble protein, calcium, magnesium, iron, copper, sodium, potassium, inorganic phosphate, oxalate and chloride as minor components were found in all types of calculi. The cholesterol stones had higher content of total cholesterol, phospholipids, fatty acids (esterified), inorganic phosphate and copper compared to mixed and pigment stones. The mixed stones had higher content of iron and triglycerides than to cholesterol and pigment stones. The pigment stones were richer in total bilirubin, bile acids, calcium, oxalate, magnesium, sodium, potassium, chloride and soluble protein compared to cholesterol and mixed stones. Although total cholesterol was a major component of cholesterol, mixed and pigment gall stone in Haryana, the content of most of the other lipids, cations and anions was different in different gall stones indicating their different mechanism of formation.     

横断山地区兰科植物区系的研究

兰科在横断山地区是维管束植物中的大科之一，共有91属，363种及9变种。 4属为我国特有属，其中1属为本地区所特有；155种及9变种为我国特有种。  其中69种及5变种为本地区所 特有。本文对属、种进行了分析，并对全部种的分布格局作了详细的介绍，概述了本地区兰科植物的区系组成及特点。本文从兰科植物属、种的分布提出了四川峨眉山是东亚植物区中划分中国-喜马拉雅植物亚区和中国-日本植物亚区的分界线上的一个重要的点的看法。
