婚变情变 归根到底是细胞变了？ Character of things in the final analysis is cell changed?

一项趣味调查 七年之痒 或因七年之后你就不是你 An interesting survey seven year itch or for seven years later you will not you

　　最近离婚的人特别多。

Recently divorced people much more special.

　　董洁和潘粤明前些日子离了，有网友翻出他们旧日一条微博“恋爱三年结婚三年，明年……痒一痒”，感慨“七年之痒”一语成谶。

Fast becomes and the other day from,Netizens to turn out their old a micro bo"Love three years three years of marriage,Next year...Itch itchy a",regrets"Seven year itch"A language into compared.

　　转眼，王石又在结婚N年后，痒一痒，离了。

a,Wang shi and in marriage N years later,Itch itchy a,from.

　　七年、七年又七年，为什么婚姻总是熬不过时间？现在有了一个说法：据说这是因为，你全身的细胞7年正好更新一个轮回，你已不是7年前的你，爱当然也就不是当年的爱了。

Seven years/Seven years and seven years,Why marriage always cook but time?Now there is a saying:It is said that this is because,Your whole body cells 7 years just update a cycle,You have not seven years ago you,Love also is not the love.

【微博说】“7年之痒”因全身细胞7年换一遍 [Micro bo said]"Seven year itch"Because body cells 7 years in again

　　董洁和潘粤明刚刚分手，并有演变为“谁才是主责”的年度悬疑大片之势；王石就携“敦亲王福晋”横空杀出，据说他将10处房产中7处给了前妻，转身给“福晋”专心烹盘红烧肉。

Fast and becomes just broke up,And evolution for"Who is the Lord"Annual suspense big trend;Wang shi will join"Dun prince fujin"Uplift fight,It is said that he will be 10 homes in seven place gave his ex-wife,Turned to"fujin"Concentrate on cooking disc braise in soy sauce meat.

　　董潘婚姻正好7年，王石更和前妻分居多年，让不少网友感慨：“果然什么样的爱情也扛不过时间。”可转眼就有“学术帝”出面，抛出了“惊人炸弹”。

Dong pan marriage just seven years,Wang shi more and ex-wife separation for many years,Let not a few net friend regrets:"Indeed as expected what kind of love also carry but time."Can we have"Academic emperor"to,out"Amazing bomb".

　　“你以为是什么让爱走到终结？因为人体的细胞会新陈代谢，每三个月会替换一次，随着旧细胞的死去，新细胞华丽诞生。由于不同细胞代谢的时间和间隔的不同，将一身细胞全部换掉。需要七年，也就是说，在生理上，我们每七年就是另外一个人。你就是你，但你也不是你了。”最近，网络上出现了“七年之痒”这样的原因解读。

"Do you think what makes love went to the end?Because body cells metabolism,Every three months to replace a,As the old cells die,The new cells luxuriant was born.Because different cell metabolism of time and space is different,Will a cell all change.Need seven years,That is,In the physical,We every seven years is another person.You are what you,But you are not you."recently,Appeared on the network"Seven year itch"Such reason to interpret.

　　这条微博引起热议，被网友转发了5000多次，有人说：难怪现在我的脾气跟以前一点也不一样，原来是换了一个人。

This article micro bo cause of hot debate,Be net friend forwarding the more than 5000 times,Some say:It is no wonder that now my temper with a little before is different also,It is in a man.

　　不过，我们的细胞是不是真的7年一个轮回？我们的感情又是不是靠细胞说了算？这是个好问题。

but,Our cell really 7 years a cycle?Our feelings and is by cells have the final say?This is a good question.

【医生说】有的细胞更新快 有的细胞一生不变 [The doctor said]Some cell updated quickly some cell life unchanged

　　究竟我们的细胞多久完成一个轮回？金陵晚报记者为此访问了南京多位医生，而对于这个问题，不同科室的医生给出的答案截然不同。

After all our cell how long to complete a cycle?Jinling evening news reporter visited nanjing for more than the doctor,For this problem,Different department doctor give different answers.

s“脑”换不了：陪你一生只此一次 "brain"In the:Stay with you for life once for all

　　南京脑科医院精神科专家、南京神经精神病学研究所副所长姚志剑教授说，大脑中最主要的是神经元细胞，这大概也是我们身上最珍贵的细胞，因为它一生的更新次数为：0。

Nanjing brain hospital psychiatric experts/Nanjing neuropsychiatry deputy director of the institute YaoZhiJian professor said,The brain is the most main neurons,This is probably our most precious body of the cell,Because it updates of life:0.

　　“我们上课的时候老师说，神经元细胞就像一篮子鸡蛋，坏掉一个就少一个，没得替换修补。”姚志剑说，我们大脑中的神经元细胞大概在一千亿左右，随着年龄渐增，它们也会渐渐凋零，而且没有“新兵”可以替补。当凋零到一定阶段，你就可能要面对某些问题了，比如老年性痴呆。当然，还有一些因素会加速它的凋零，那些就更伤大脑了。

"We the class teacher said,Neurons is like a basket of eggs,Bad off a little one,Have no replacement repair."YaoZhiJian said,Our brain neurons probably at around one hundred billion,With increasing age,They also will die away,And no"recruits"Can substitute.When fall to a certain stage,You may have to face some problems,Such as senile dementia.Of course,There are some factors will accelerate its die,Those who are more hurt the brain.

“心”不易变：它们向脑细胞看齐 "heart"Won't get:They look to brain cells

　　南京鼓楼医院心脏科徐伟教授说，心脏中的主体细胞是心肌细胞，它基本上和脑细胞看齐——陪你一世，不可再生。

Nanjing gulou hospital heart said professor xu,The heart of the main body cells are myocardial cells,It basically and more brain cells - accompany you forever,non-renewable.

　　“就拿心梗患者来举例吧。心梗患者如果抢救不及时，大范围心肌缺血坏死，那么患者就算救治成功，心功能也非常差。因为坏死的这部分心肌细胞无法再生，这部分心肌就变成了疤痕组织，失去了原本的作用。”

"Take the example of myocardial infarction patients with it.Myocardial infarction patients if not timely rescue,A wide range of myocardial ischemic necrosis,So even if treatment in patients with success,Cardiac function is also very poor.Because this part of the necrotic myocardium cell cannot regeneration,This part of the myocardial becomes a scar tissue,Lost the original function."

　　徐伟说，现在医学界也有观点认为心脏细胞有再生可能，同时也在研究是否可以通过干细胞技术，促进心肌细胞再生，不过这些都还在探索阶段。基本上，心脏领域的学者们还是认为，心肌细胞缺乏再生能力。

, xu wei said,Now the medical profession also have ideas that heart cells may have regeneration,At the same time also in research whether can through the stem cell technology,Promote the myocardial cell regeneration,But these are still in the exploratory stage.basically,In the field of heart scholars still think,Lack of myocardial cell regeneration.

“皮”变得快：历时28天的“移动战” "skin"Become fast:Duration 28 days"Mobile warfare"

　　南京鼓楼医院皮肤科专家包军说，皮肤细胞大军种类太多，有角质形成细胞、黑素细胞等等，咱们就先说说和外观关系最密切的表皮细胞。

Nanjing gulou hospital dermatological department experts BaoJun said,Skin cells army kinds too much,Have horniness forming cell/Melanocyte, etc,Let's say first and appearance of the most closely related epidermal cells.

　　爱美容的女士可能都听过表皮细胞28天一更新的说法，这个说法本身是正确的。因为我们的皮肤暴露在外，经常接受各种刺激，所以更新还是很频繁的。不过包军说，这种更新不是直接分裂替换一批“新兵”，而是一场“细胞移动战”。细胞在基底层分裂新生后，会一层层向表皮移动，当它们花了14天到达表面角质层时，其实就已经死亡；再接下来的14天内，它们会逐渐从角质层脱落，换上下面一批。

Love beauty lady might have heard the epidermal cells 28 days update statement,This statement itself is correct.Because our skin exposed,Often accept various stimuli,So update or very frequent.But BaoJun said,This update is not direct division to replace a batch"recruits",But a"Cell mobile warfare".Cells in the base layer division after freshmen,To the skin layers will move,When they spent 14 days to reach the surface when the cuticle,In fact it has died;Then the next 14 days,They will gradually fall off from the cuticle,Put on a batch below.

“血”常更新：红细胞能活120天 "blood"Frequently update:Red blood cells can live for 120 days

　　解放军第454医院血液科主任廖辉说，以血液中的三大细胞为例，红细胞120天更新一次，血小板细胞一般是7-9天更新一次。至于白细胞则比较复杂，因为它种类繁多，更新的时间也有长有短，短则几个小时，长则数月。以红细胞为例，寿终正寝的红细胞会在脾脏内被分解，组成红细胞的物质重新被机体利用制造新的红细胞。如果以它为准，那么120-140天左右，我们将“换血”成功。

The people's liberation army 454 hospital hematology department director LiaoHui said,With the blood of the three large cell, for example,Red blood cells 120 updated once a day,Platelet cells is generally 7-9 days update a.As for the leucocyte is more complicated,Because it variety,Update time also has long have short,Short is several hours,Long months is.To red blood cells as an example,Die of red blood cells in the spleen of the decomposition,Red blood cells of the material to be the use of making new red blood cells.If with it shall prevail,Then 120-140 days or so,We will"unforeseen"success.

　　此外，人体的胃上皮细胞的周期是24小时，骨髓细胞是18小时，肝脏细胞能活5个月，味蕾细胞只能活2周，肺表面细胞寿命是2-3周，眼部只有角膜细胞在不断更新。南京市中医院脑病科王敬卿主任医师替记者查阅了这些资料，并告诉记者，如果将不同的细胞综合在一起计算，或许能算出细胞的平均年龄，不过要是真的全身细胞全部“死亡”一次，恐怕这个人的人生也就宣告完结了，因为有些细胞真的无法再生，你得爱惜着点用。(记者 朱菁菁 报道)

In addition,Human gastric epithelial cell cycle is 24 hours,Bone marrow cells are 18 hours,Liver cells can live five months,Taste bud cells can live only two weeks,Lung surface cell life is 2 to 3 weeks,Eye only corneal cells in constantly updated.Nanjing institute of traditional Chinese medicine encephalopathy families WangJingQing chief physician for reporters refer to these material,And told reporters,If the different cell integrated together calculation,May be able to work out the average age of the cells,But what if it is true the whole body all cells"death"a,I'm afraid this man's life also declared the end,Because some of the cells are really can't regeneration,You have to love the point with.(Reporter ZhuJingJing reports)
