精准医疗又叫个性化医疗，是指以个人基因组信息为基础，结合蛋白质组，代谢组等相关内环境信息，为病人量身设计出最佳治疗方案，以期达到治疗效果最大化和副作用最小化的一门定制医疗模式。因此相较传统医疗，精准医疗具有针对性、高效性及预防性等特征。

刘如银说：美国的精准医疗主要是围绕着基因组、蛋白组等方面的检测，也就是围绕分子生物学的特性，针对个体化的病理特征进行治疗。而我们所关注的不仅如此，更是系统化的，全过程、全要素、全局性的对医疗过程和临床实践进行优化。我们所指的精准医疗也是针对每一个病人的具体病情，正确选择并精确的应用适当的治疗方法。刘如银认为：精准医疗的最终目标是以最小化的医源性损害、最低化的医疗资源耗费去获得最大化的病患的效益，其前景不可限量。

精准医疗要做到个性、高效及预防的关键在于筛查和诊断，因此基因测序等检测诊断技术的发展是关键。成本的下降让基因测序商业化市场的打开成为可能，基因测序技术的成熟和商用经过了多年的发展，1980 年自动测序仪出现，2001 年完成了人类基因组框架图标志着这一技术的成熟，2007 年二代基因测序技术大幅降低测序成本，使得这一技术应用出现可能，以走在前列的Illumina 公司为例，该公司自2007 年起把当时每个基因组的测序成本费用从1000万美元降到了当下的1000 美元， 根据Illumina 公司数据，全球NGS(二代基因测序)的应用市场规模预计为200 亿美元，药品研发和临床应用是增速最快的领域，增速超过15%，肿瘤诊断和个性化用药是最有应用前景的领域，市场规模120亿美元。乐土投资与Illumina以及新一代的基因检测公司Genalyte, Centrillion都有着合作关系。

You can:

To bind a keyboard macro to a key use <code>C-x C-k b</code>. To avoid problems caused by overriding existing bindings, the key sequences <code>C-x C-k 0</code> through <code>C-x C-k 9</code> and <code>C-x C-k A</code> through <code>C-x C-k Z</code> are reserved for your own keyboard macro bindings.  You can, however, bind a keyboard macro to whatever you like.

Basic Keyboard Macro (`(info "(emacs) Basic Keyboard Macro")')

Keyboard macros can be used to automate or repeat tedious editing tasks in Emacs.


Basic Use

[F3], or [C-x (]
Start defining a macro.
[F4], or [C-x )]
Stop defining a macro.
[F4], or [C-x e]
Execute a macro
[C-u 37 C-x e] or [C-u 37 F4]
Execute a macro multiple times, using prefix argument
[C-u 0 C-x e]
Execute a macro until the end of the buffer

Example usage

Consider the standard *scratch* buffer: 

;; This buffer is for notes you don't want to save, and for Lisp evaluation.
;; If you want to create a file, visit that file with C-x C-f,
;; then enter the text in that file's own buffer.

Suppose you want to remove the first occurrence of the letter "a" on every row in that piece of text. You could write a regular expression to do the job, but let's assume you want to use a keyboard macro this time.

  1. Make sure point is at the start of the buffer.
  2. Hit C-x ( to start recording your macro. Note: If you hit C-g or if an error occurs, your keyboard macro recording will stop.
  3. Hit C-s followed by a to find the first "a". Now, point is right after the first "a" in the text.
  4. Hit backspace to delete that "a".

The first occurrence of "a" of the first line has been deleted. Let's move point to the beginning of the next line and then stop recording.

  1. Hit C-e C-f to move point to the beginning of the next line.
  2. Hit C-x ) to finish the recording of our macro.

The macro you have just recorded performs the operation of removing the first occurrence of "a" it can find and then moving point to the next line.

  1. Hit C-x e once to call that macro.
  2. Continue hitting e to call it several times. Hit any other key to get out of the macro repetition.

Naming and saving macros

You can:

  • give a name to the most recently defined macro (C-x C-k n)
  • bind it to a key sequence (C-x C-k b)
  • insert it in the current buffer as lisp code (M-x insert-kbd-macro).

Save Keyboard Macro (`(info "(emacs) Save Keyboard Macro")')


To bind a keyboard macro to a key use C-x C-k b. To avoid problems caused by overriding existing bindings, the key sequences C-x C-k 0 through C-x C-k 9 and C-x C-k A through C-x C-k Z are reserved for your own keyboard macro bindings. You can, however, bind a keyboard macro to whatever you like.

Variables

Variables can be stored in lisp or in registers. Here's an example using lisp: 

[M-: (setq x 1)]
<F3>
Line number [C-u M-: x]
[M-: (setq x (+ x 1))]
<F4>

Now execute the macro four times with the command C-x e e e e and you get:

line number 1
line number 2
line number 3
line number 4
