泽苔草的花器官发生

本文用扫描电镜观察了泽苔草的花器官发生过程，观察结果表明：花萼以螺旋状方式向心发生，花瓣以接近轮状方式近同时发生，不存在花瓣雄蕊复合原基。雄蕊和心皮均以轮状向心方式发生，6枚雄蕊分两轮分别在对萼和对瓣的位置先后发生，至发育的后期排成一轮，但仍分别处于对萼和对瓣的位置；随后发生的第一轮3个心皮原基与3枚萼片相对，第二、三轮心皮原基分别为1~3个，与前一轮心皮相间排列向心发生。本文首次揭示了泽苔草花被的外轮3个萼片螺旋状发生方式，这种螺旋状方式很可能是泽泻科植物的花部结构在进化过程中适应环境而保留下来的一种较原始的叶性特征。     

小花草玉梅变态花萼片的形态学研究

运用宏观形态学和光学显微镜方法,对小花草玉梅Anemone rivularis var. flore-minore正常花和变态花的花被片进行了比较研究,以期更好地理解该分类群花被片变态过程。研究结果显示,该植物正常花中的花被片一般5(-8)枚,白色,倒卵形,全缘,可达1.3×0.5 cm,叶脉为开放的二叉分枝状,只在背面的顶端具少量毛被;其上表面未观察到气孔器,下表面具少量的气孔器。变态花中的花被片数目可达20枚;变态花被片显示出苞片或叶的形态特征:具网状脉,绿色,倒卵形或椭圆形,可达5×3 cm,两面密被毛,全缘或3裂,裂片边缘又浅裂或有锯齿,背腹面均具气孔器且数目随着变态程度的增加而增加。正常花被片与强烈变态的花被片之间在数目、形状、大小、颜色、边缘是否分裂、脉序及气孔器和毛被的数目等方面存在着连续的变态梯度。小花草玉梅变态花被片的叶状特征表明,这种表现叶性器官特征的变态可能是一种返祖现象,被子植物花萼片可能与苞片具有相同的起源。

陇西栽培蒙古黄芪酯酶同工酶数量分析

为了对陇西栽培蒙古黄芪（Astragalus membranaceus (Fisch.) Bge. var. mongholicus (Bge.) Hsiao）的优质高产和良种选育提供一定依据，本文采用垂直板聚丙烯酰胺凝胶电泳技术，对该地区栽培蒙古黄芪种子酯酶同工酶进行了研究。结果表明：该地栽培蒙古黄芪是一个复杂的异质群体；种子酯酶同工酶电泳技术是检验蒙古黄芪种内变异的一种有效手段。     

冠果草的胚胎学研究

冠果草花药壁的发育为单子口十型，绒毡层为周原质团型。小孢子母细胞减数分裂为连续型，四分体呈左右对称式排列，成熟花粉为三细胞型。双珠被，假厚珠心，倒生胚珠。胚囊发育为葱型，成熟胚囊的特点是两个极核分别位于中央细胞两端，不融合成次生核。受精过程中，一个精于与卵核融合形成合子，另一精子先与珠孔端极核融合，之后受精极核再移动到合点端与另一极核融合，形成初生胚乳核。胚的发育为石竹型。成熟胚呈马蹄形，具有2片真叶。胚乳发育为沼生目型。随着胚的发育，胚乳细胞逐渐解体，成熟种子中无胚乳。

肋柱花属的系统研究

本文对肋柱花属的属下分类、系统发育和地理分布等方面进行了深入研究。文用分支系统学的方法和原理，用计算机PAUP程序处理，获得了几个最简约的支序图。  肋柱花属属于龙胆亚族辐状花冠群，在这群中，论亲缘关系它与辐花属最近，与獐牙菜属次之，而与黄秦艽属关系较远。  獐牙菜属在进化程度上较肋柱花属低，因此它被选为肋柱花属的外类群。 经过支序分析，肋柱花属的18个种根据Hennig的“共近裔性原则”可组合为三个组，其中肉质根茎组为较原始的组，肋柱花组为中级进化水平的组，合萼组是进化程度最高的组。 肋柱花属是北温带分布型的属，分布于亚洲、欧洲及北美洲，直达北极。从种的地理分布型分析，表明秦岭一横断山区是本属的起源与分化中心。 随文报道了一个新组、一个新种和一个新变种。  研究了全部种类的命名模式。     

裂瓜属的研究

The classical and numerical taxonomy, palynology and the geographical dis- tribution of the Genus Schizopepon are dealt with in the present paper.  Having comme- nted on various opinions regarding the systematic position of the genus, the present au- thors consider that C. Jeffrey’s treatment of Schizopepon as a new and monogeneric tri- be, Schizopeponeae, should be supported.      The gross morphological characters in the genus are assessed from the taxonomic point of view.  Some characters, such as stamens with an elongated connective or not, different insertions of ovules and various forms of ovaries and fruits, may be used for distinguishing subgenera.      The pollen grains of all the species were observed under light microscope (LM) and scanning electron microscope (SEM).  The results show that a strong differentiation has taken place in the pollen of the genus, and in consequence it may be regarded as an important basis for dividing subgenera and species. Especially it should be pointed out that degrees of development of colpi and positions of ora are positively correlated with the external characters used for distinguishing subgenera.      According to the morphological and palynological characters, the genus Schizopepon may be divided into three subgenera and eight species: 1. Subgenus Schizopepon: 5 spe- cies, S. bryoniaefolius Maxim., S. monoicus A. M. Lu et Z. Y. Zhang, S. dioicus Cogn., S. longipes Gagnep. and S. macranthus Hand.-Mazz.; 2. Subgenus Rhynchocarpos A. M. Lu et Z. Y. Zhang: 1 species, S. bomiensis A. M. Lu et Z. Y. Zhang; 3. Subgenus Neoschi- zopepon A. M. Lu et Z. Y. Zhang: 2 species, S. bicirrhosus (C. B. Clarke) C. Jeffrey and S. xizangensis A. M. Lu et Z. Y. Zhang.      The 8 OTU’s including all the species of this genus and 31 characters, of which 16 are morphological characters and 15 palynological characters, were used in the numerical taxonomic treatment.  After standardization of characters, the correlation and distance matrices were computed.  The correlation matrices are made to test the various clustering methods.  At last, the UPGMA clustering method was selected and its result is shown in the form of phenogram.  The result of numerical analysis is similar to that of the classical classification.      Schizopepon Maxim. is a genus of East Asia-Himalayan distribution. China has all 8 species and 2 varieties, of which 6 species are endemic. Based on the statistics of spedies number, the distribution centre of the genus is considered to be in the Hengduan Mountains (Yangtze-Mekong-Salwin water divides) and the adjacent areas of the southwest China.

芍药属牡丹组分类新注

自我们近年发表一系列牡丹组分类文章以来, 国内外基本上赞同我们8个种的分类系统,但对一些问题仍有不同见解。本文进一步申述牡丹Paeonia suffruticosa Andrews 是一个独立的种而不是人工杂种, 以及银屏牡丹P. suffruticosa ssp. yinpingmudan是牡丹P. suffruticosa的野生类型而不是逸生的P. ostii的理由。上述论点也得到了分子树的支持。P. jishanensis T. Hong & W. Z. Zhao是一个合法名称, 而P. spontanea (Rehder) T. Hong & W. Z. Zhao则确实是一个多余名。太白山紫斑牡丹的学名应是P. rockii ssp. atava (Brühl) D. Y. Hong & K. Y. Pan, 因此P. moutan Sims ssp. atava Brühl不应是可疑的分类群。本文还对Halda的6个组合和两个杂交种名作了处理。结果, 本文包括了5个新异名和一个新组合。     

Women in sports: the applicability of common national reference intervals for inflammatory and coagulation biomarkers (HemSter Study)

IntroductionIntensive physical activity causes functional and metabolic changes in the athlete’s organism. The study aimed to verify the common national available reference intervals (RIs) for common inflammatory and screening coagulation tests in a population of healthy young female athletes.Materials and methodsOne hundred and twenty-one female athletes (age range: 16–34), from various sports disciplines (water polo, handball, volleyball, football, basketball), were included in the study. All participants completed the international physical activity short-form questionnaire. Blood samples were collected between 8–10 am, after an overnight fast, before any physical activity. Reference intervals were determined according to Clinical & Laboratory Standards Institute EP28-A3C Guidelines.ResultsCalculated RIs for white blood cell count (WBC), prothrombin time (PT), and activated partial thromboplastin time (APTT) ratio were in accordance with the common national RIs. Calculated RI for C-reactive protein (CRP) was lower (< 2.9 mg/L) than the proposed cut-off for a healthy population (< 5.0 mg/L). Reference interval for fibrinogen was higher (1.9–4.4 g/L), than the available RIs (1.8–3.5 g/L). D-dimer cut-off value was set at 852 µg/L fibrinogen equivalent units (FEU), higher than the proposed 500 µg/L FEU for venous thromboembolism (VTE) exclusion.ConclusionsThe applicability of the available RIs for WBC count, PT, and APTT-ratio was confirmed. However, RIs for CRP and fibrinogen differed significantly than the available common national RIs for the healthy non-athletes’ population. A higher cut-off for D-dimers should be extensively verified before implementation for VTE diagnosis exclusion in a group of healthy young female athletes.
