Advantages and disadvantages of urbanization

Nowadays,urbanization has been a topic of heated discussion for a long time.Some people are in favor,while others are opposed.From my point of view,urbanization is a double-edged sword;it has not only advantages but also disadvantages.

In general,the advantages of urbanization can be concluded as follows. Firstly, urbanization can quicken our steps to catch up with the developed countries.As is universally acknowledged,the developed countries are making rapid developments,and as a result,are all highly urbanized.Secondly,urbanization will do good to solving the problem of unemployment,since it can create more job opportunities for the unemployed.Besides, urbanization will free a great quantity of farmers from the fields,therefore,the dream of agricultural mechanization in our country will easily come true.Finally,urbanization can improve the living standards of the migrants who move to the urban area.

Nevertheless,it’s obvious that there are still many disadvantages of urbanization.To start with,administration of the increasing population in urban area might be a great challenge to the government.In addition,people have to stay in front of the computer screens from morning till dusk.Thus,their health level is declining day by day because of the radiation and some individuals even die from it.What’s more,a raising number of the youth move out to big cities in spite of there being their old parents in the hometown who seriously need someone to take care of them.However,they are off for a long time,leaving their parents nothing but loneliness and https://www.sodocs.net/doc/bc14886664.html,st but not least,in the urbanization society,the scheme against each other is gradually replacing the harmonious with each other.Long before,people are at peace with each other and the surrounding environment without the side effect of urbanization.However,in today’s life,money and snobbery tie them down,making them run after fame and gain even using unscrupulous tactics,such as forcing their own blame upon the innocent.

It appears that as for urbanization,the disadvantages are more than the advantages.But as far as I’m concerned,the advantages are certain while the disadvantages can be transformed or avoided.We can subjectively change our minds towards it and make most of its advantages.Undeniablely,it is urbanization that suggests country is developing.

To sum up,every coin has two sides,and so does urbanization.We should make its advantages serve us and never be a slave of it just because of its disadvantages.

Good morning, dear professors! I fell so glad to meet all of you here for this interview.First,I would like to briefly introduce myself, my name is XXX from Zhengzhou Institute of Aeronautical Industry Management, I am majoring in Electrical engineering and its automation, I will finish my undergraduate education in July this year. I think that most of us watched the movie 1942, in which Yanjin is mentioned at least four times, yeah, it is my hometown, Henan Province, which is famous for Ancient Yellow River forest park. And now, I am trying my best for obtaining a key to Guizhou University. Then it comes to my family, my hobbies and personalities. There are four members in my family: my parents, my sister and me.

In a word, I am looking forward to making a solid foundation for my future profession after three years` study here. And I promise that I would never let you down.

脐带干细胞综述

脐带间充质干细胞的研究进展 间充质干细胞(mesenchymal stem cells,MSC S )是来源于发育早期中胚层 的一类多能干细胞[1-5],MSC S 由于它的自我更新和多项分化潜能,而具有巨大的 治疗价值 ,日益受到关注。MSC S 有以下特点:(1)多向分化潜能,在适当的诱导条件下可分化为肌细胞[2]、成骨细胞[3、4]、脂肪细胞、神经细胞[9]、肝细胞[6]、心肌细胞[10]和表皮细胞[11, 12];(2)通过分泌可溶性因子和转分化促进创面愈合;(3) 免疫调控功能,骨髓源(bone marrow )MSC S 表达MHC-I类分子,不表达MHC-II 类分子,不表达CD80、CD86、CD40等协同刺激分子,体外抑制混合淋巴细胞反应,体内诱导免疫耐受[11, 15],在预防和治疗移植物抗宿主病、诱导器官移植免疫耐受等领域有较好的应用前景;(4)连续传代培养和冷冻保存后仍具有多向分化潜能,可作为理想的种子细胞用于组织工程和细胞替代治疗。1974年Friedenstein [16] 首先证明了骨髓中存在MSC S ,以后的研究证明MSC S 不仅存在于骨髓中,也存在 于其他一些组织与器官的间质中:如外周血[17],脐血[5],松质骨[1, 18],脂肪组织[1],滑膜[18]和脐带。在所有这些来源中,脐血(umbilical cord blood)和脐带(umbilical cord)是MSC S 最理想的来源,因为它们可以通过非侵入性手段容易获 得,并且病毒污染的风险低,还可冷冻保存后行自体移植。然而,脐血MSC的培养成功率不高[19, 23-24],Shetty 的研究认为只有6%,而脐带MSC的培养成功率可 达100%[25]。另外从脐血中分离MSC S ,就浪费了其中的造血干/祖细胞(hematopoietic stem cells/hematopoietic progenitor cells,HSCs/HPCs) [26, 27],因此,脐带MSC S (umbilical cord mesenchymal stem cells, UC-MSC S )就成 为重要来源。 一.概述 人脐带约40 g, 它的长度约60–65 cm, 足月脐带的平均直径约1.5 cm[28, 29]。脐带被覆着鳞状上皮,叫脐带上皮,是单层或复层结构,这层上皮由羊膜延续过来[30, 31]。脐带的内部是两根动脉和一根静脉,血管之间是粘液样的结缔组织,叫做沃顿胶质,充当血管外膜的功能。脐带中无毛细血管和淋巴系统。沃顿胶质的网状系统是糖蛋白微纤维和胶原纤维。沃顿胶质中最多的葡萄糖胺聚糖是透明质酸,它是包绕在成纤维样细胞和胶原纤维周围的并维持脐带形状的水合凝胶,使脐带免受挤压。沃顿胶质的基质细胞是成纤维样细胞[32],这种中间丝蛋白表达于间充质来源的细胞如成纤维细胞的,而不表达于平滑肌细胞。共表达波形蛋白和索蛋白提示这些细胞本质上肌纤维母细胞。 脐带基质细胞也是一种具有多能干细胞特点的细胞,具有多项分化潜能,其 形态和生物学特点与骨髓源性MSC S 相似[5, 20, 21, 38, 46],但脐带MSC S 更原始,是介 于成体干细胞和胚胎干细胞之间的一种干细胞,表达Oct-4, Sox-2和Nanog等多

脐带血间充质干细胞的分离培养和鉴定

脐带血间充质干细胞的分离培养和鉴定 【摘要】目的分离培养脐带血间充质干细胞并检测其生物学特性。方法在无菌条件下用密度梯度离心的方法获得脐血单个核细胞,接种含10%胎牛血清的DMEM培养基中。单个核细胞行贴壁培养后,进行细胞形态学观察,绘制细胞生长曲线,分析细胞周期,检测细胞表面抗原。结果采用Percoll(1.073 g/mL)分离的脐血间充质干细胞大小较为均匀,梭形或星形的成纤维细胞样细胞。细胞生长曲线测定表明接后第5天细胞进入指数增生期,至第9天后数量减少;流式细胞检测表明50%~70%细胞为CD29和CD45阳性。结论体外分离培养脐血间充质干细胞生长稳定,可作为组织工程的种子细胞。 【关键词】脐血;间充质干细胞;细胞周期;免疫细胞化学 Abstract: Objective Isolation and cultivation of mesenchymal stem cells (MSCs) in human umbilical cord in vitro, and determine their biological properties. Methods The mononuclear cells were isolated by density gradient centrifugation from human umbilical cord blood in sterile condition, and cultured in DMEM medium containing 10% fetal bovine serum. After the adherent mononuclear cells were obtained, the shape of cells were observed by microscope, then the cell growth curve, the cell cycle and the cell surface antigens were obtained by immunocytochemistry and flow cytometry methods. Results MSCs obtained by Percoll (1.073 g/mL) were similar in size, spindle-shaped or star-shaped fibroblasts-liked cells. Cell growth curve analysis indicated that MSCs were in the exponential stage after 5d and in the stationary stages after 9d. Flow cytometry analysis showed that the CD29 and CD44 positive cells were about 50%~70%. Conclusions The human umbilical cord derived mesenchymal stem cells were grown stably in vitro and can be used as the seed-cells in tissue engineering. Key words:human umbilical cord blood; mesenchymal stem cells; cell cycle; immunocytochemistry 间充质干细胞(mesenchymal stem cells,MSCs)在一定条件下具有多向分化的潜能,是组织工程研究中重要的种子细胞来源。寻找来源丰富并不受伦理学制约的间充质干细胞成为近年来的研究热点[1]。脐血(umbilical cord blood, UCB)在胚胎娩出后,与胎盘一起存在的医疗废物。与骨髓相比,UCB来源更丰富,取材方便,具有肿瘤和微生物污染机会少等优点。有人认为脐血中也存在间充质干细胞(Umbilical cord blood-derived mesenchymal stem cells,UCB-MSCs)。如果从脐血中培养出MSCs,与胚胎干细胞相比,应用和研究则不受伦理的制约,蕴藏着巨大的临床应用价值[2,3]。本研究将探讨人UCB-MSCs体外培养的方法、细胞的生长曲线、增殖周期和细胞表面标志等方面,分析UCB-MSCs 作为间充质干细胞来源的可行性。

In my spare time, I like to do anything relating to English such as listening to English songs, watching English movies or TV programs, or even attending the activities held by some English clubs or institutes. I used to go abroad for a short- term English study. During that time, I learned a lot of daily life English and saw a lot of different things. I think language is very interesting. I could express one substance by using different sounds. So I wish I could study and read more English literatures and enlarge my knowledge 简单的英文自我介绍范文篇【二】 My name is___________ . There are 4 people in my family. My father is a Chemistry teacher. He teaches chemistry in senior high school. My mother is an English teacher. She teaches English in the university. I have a younger brother, he is a junior high school student and is preparing for the entrance exam. I like to read English story books in my free time. Sometimes I surf the Internet and download the E- books to read. Reading E- books is fun. In addition, it also enlarges my vocabulary words because of the advanced technology and the vivid animations. I hope to study both English and computer technology because I am interested in both of the subjects. Maybe one day I could combine both of them and apply to my research in the future.
