答案

参考答案:

中医病证诊断:脱疽,湿热毒盛证 西医疾病诊断:血栓闭塞性脉管炎(Ⅲ期)

解析:中医辨病辨证依据:青年男性,左脚肿痛,足大趾发黑溃烂,剧痛难忍,属中医"脱疽"范畴。气血瘀滞,郁久化热,或湿热入侵,湿热蕴结,则患肢剧痛,局部肿胀,皮色紫暗,浸淫蔓延,溃破腐烂,肉色不鲜;热盛伤阴,则身热口干,便秘溲赤;舌红、苔黄腻、脉弦数为湿热毒盛之象。西医诊断依据:根据患者肢体有发作性疼痛、间歇性跛行、足背动脉搏动减弱或消失,后期出现溃烂,伴游走性表浅静脉炎者即可诊断。患者青年男性,患者3年前出现间歇性跛行,四月前出现左足肿痛,左大趾发黑溃烂,剧痛难忍。胫后动脉、足背动脉搏动均消失。B超检查提示:左小腿胫后及足背动脉闭塞。符合上述要求,故诊断明确。

                             Stop  Spam

   When I first got an e-mail account ten years ago, I

received communications only from family, friends, and

  colleagues. Now it seems that every time I check my e-mail, I

have an endless series of advertisements and other

  correspondence that do not interest me at all. If we want e-mail

to continue to be useful, we need specific laws that make

spamming(发送垃圾邮件)a crime.

        If lawmakers do not do something soon to prohibit spam,

  the problem will certainly get much worse. Computer programs

  allow spammers to send hundreds of millions of e-mails almost

  instantly. As more and more advertisers turn to spam to sell

  their products,  individual(个人的) e-mail boxes are often

  flooded with spam e-mails. Would people continue to use e-mail

   if they had to deal with an annoying amount of spam each time?

        This problem is troubling for individuals and companies as

  well. Many spam e-mails contain computer viruses that can

   shut down the entire network of a company. Companies rely on

  e-mail for their employees to communicate with each other.

  Spam frequently causes failures in their local communications

  networks, and their employees are thus unable to communicate

effectively. Such a situation results in a loss of productivity and

requires companies to repeatedly repair their networks. These

computer problems raise production costs of companies, which

are, in the end, passes on to the consumer.

   For these reasons, I believe that lawmakers need to

legislate(立法) against spam. Spammers should be fined,  and

perhaps sent to prison if they continue to disturb people. E-mail

is a tool which helps people all over the world to communicate

conveniently, but spam is destroying this convenience.
