The slow progress of researches on pulmonary stem cells up to date has its root in the complex structure of pulmonary tissues and respiratory tracts, which is demonstrated by the facts that the respiratory system is composed of at least 40 types of cells, plus that the growth, renewal, and regeneration rate or capacity of respiratory epithelium are extremely limited. Mean while, there have been no specific stem cell markers for pulmonary and lung cancer, so researchers rely on stem cell markers borrowed from other systems to search for stem cells in pulmonary system.

目前对于肺干细胞的研究进展缓慢，究其原因主要是肺组织和气道具有复杂的内在结构，呼吸系统至少包含40种不同类型的细胞，呼吸上皮本身只有极低的生长更新率和非常有限的再生能力，同时肺干细胞的表面标志物也缺乏特异性，只能借助其他组织已知的干细胞标记物进行对比观察。

Irrigation during over-winter promoted significantly N absorption and accumulation, increased N content in the plants at early stage (before 10, April) and final single stem weight, and reduced stem flowering percentage and florets per cyme, leading to an improved quality of rush stem. With the increased level of N application, N content and accumulation in plants, stem flowering percentage and florets per cyme were significantly increased.

越冬期灌水能显著促进植株对氮的吸收和积累，增加前期（10/4前）植株含氮量和收获期单茎干重，显著减少草茎开花率和平均每花序小花数，从而改善草茎品质；随着施氮水平的提高，植株氮吸收和含氮量相应增加，开花率及平均每花序小花数显著提高。

The basal diameter, height of aerial stem, leaf length at middle stem, leaf width at middle stem, internode length at middle stem, internodes number and panicle length of 30 plants from every population were recorded. The statistics of morphological characters showed that the distribution trends of the averages of morphological characters are similar among populations. However, the coefficients of variation within population of 7 morphological characters were very different. The CV of internodes was largest and the CV of height was smallest within population. F-statistics showed that the differences of all morphological characters among populations were significant (P.01). But the differences among populations were different between different groups. The cluster analysis proved that all populations could be divided into three types: salty reed, freshwater reed and giant reed.

对来自每个种群的30个个体的基径、株高、中部叶长、中部叶宽、中部节间长、节间数、穗长7个形态特征的统计分析表明：各形态特征平均值在种群间的分布趋势相似，但变化幅度不同，株高、叶长等营养特征变化较大大，生殖特征穗长的变化较小；7个形态指标在种群内的平均变异度从大到小依次为中部节间长、中部叶宽、穗长、中部叶长、基径、节间数、株高，种群内的平均形态变异度与生境异质性有关；7个形态指标在种群间均差异显著，但多重比较分析显示显著差异主要存在于BZH、淡水生境种群和盐渍化生境种群之间，在相似生境种群间的形态差异不显著；以形态特征为依据的聚类分析支持将15个种群分为三类：盐生芦苇、淡水芦苇和巨型芦苇。

Bone marrow-derived mesenchymal stem cells are capable of chondrogenesis, making them a possible source of cells for injectable cartilage tissue engineering. There exist different ideas on the ability of mesenchymal stem cells's chondrogenesis in monolayer culture. Because of this, the effect of adult rabbit's bone marrow-derived mesenchymal stem cells chondrogenesis in monolayer culture was studied. The mesenchymal stem cells was isolated from adult rabbit's bone marrow and monolayer cultured. TGF-β1, Vit-C and Dexamethasone were used. Immunohistochemistry analyses and histological staining of H-E, Methylaniline blue and Alcian blue were performed to identify the expression of collagen type Ⅱ and cartilage associated matrix. The results showed that the induced cells expressed and produced collagen type Ⅱ and cartilage associated matrix. This suggests that the differentiation of adult rabbit's marrow-derived mesenchymal stem cells into chondrocyte in monolayer culture is feasible and may be induced by TGF-β1, Vit-C and Dexamethasone.
