The fact of the mysterious pneumonia has been widely spread in HK drives me to do a literature review on the suspected cause （i.e. coronavirus） of the SARS （Severe Acute Respiratory Syndrome）。 As a biomedical researcher， let me show you my concern and make the following suggestions.

　　神秘的非典型性肺炎正在香港廣泛傳播，于是我對(duì)引起SARS（嚴(yán)重呼吸綜合征）的病因（例如冠狀病毒）作了一下研究?，F(xiàn)在讓我從生物醫(yī)學(xué)研究者的角度給您一些建議。

　　The basic mechanism of viral attack is that the viruses replicate themself using the host's （in this case is "our"） DNA genetic replication system. By doing this， our body couldn't function well due to the massive viral replication. Supposingly， the immune cells in our body will fight off the infected viruses quickly. However， the viruses are so smart that they could be able to produce some chemical substances to cause our immune cells to die. Besides， this coronavirus is a new kind of virus which belongs to a mutated strain and our body cannot recognize it. No antibiotics have been proved to be 100 effective in treating viral infection so far. The only effective way to get rid of it is by ourselves. It likes a prolonged battle between the viruses and our immune response. In fact， viruses couldn't kill all the immune cells in a health individual. The stronger the immune function you have， the less the viral injury you get. Therefore， the degree of sickness after infection and the rate of recovery mainly depends on how strong your immune function is.

　　濾過性病毒能夠引起疾病的原因是，病毒能夠通過使用病人身體中的DNA基因復(fù)制系統(tǒng)來復(fù)制自己。如果病毒大量復(fù)制自己，則我們的身體就不能正常工作了。于是，我們身體當(dāng)中的免疫細(xì)胞就會(huì)很快的殺掉這些感染病毒。然而，這些病毒非常聰明，他們能夠產(chǎn)生某種化學(xué)物質(zhì)而導(dǎo)致我們的免疫細(xì)胞死亡。除此以外，冠狀病毒是一種新型的變異病毒，它不能被我們的身體識(shí)別。這樣，在我們的免疫系統(tǒng)和病毒之間就會(huì)展開一場(chǎng)長(zhǎng)時(shí)間的斗爭(zhēng)。實(shí)際上，病毒并不能殺死一個(gè)健康人身體中的所有免疫細(xì)胞。人身體的免疫功能越強(qiáng)，此人受病毒侵害的幾率就越小。所以，在感染病毒后的病情嚴(yán)重情況和康復(fù)的幾率基本上看此人的免疫功能有多強(qiáng)。

　　You cannot avoid the infection unless you avoid from those infected individuals/area. But， you can try your best to boost up your immune function by several regimes. Make sure you are "extremely healthy" at least during this critical period. Stronger immune function could keep the viral damage minimal even you were so unluckily being infected. Also， stronger immune function delays the onset of any detrimental effects from the viral infection. Scientists are now working on tracking the treatment and so make sure you are still surviving until an effective treatment occurs. The following suggestions aim to strengthen your immune function within a short period of time.

　　你無法避免被感染，除非你不去接觸被感染者和被感染地區(qū)。但是，你可以盡你所能調(diào)動(dòng)你的免疫系統(tǒng)，確保你處于"非常健康"的狀態(tài)，至少在這段非常時(shí)期。如果你的免疫系統(tǒng)夠強(qiáng)，就算你非常不幸的被感染上病毒，也會(huì)將病毒的侵害降到最低限度。科學(xué)家們現(xiàn)在正在研究如何治療此種肺炎，所以一定要保證你能夠活到有效治療方法研究出來之前。下面是一些在短時(shí)期內(nèi)能夠增強(qiáng)你的免疫功能的方法：

　　1） Antioxidant nutraceuticals： Antioxidants are chemicals found in foods which exert a great value in strengthening our immune system. Boost up your immune function by taking a cocktail of antioxidant supplements.

　　抗氧化劑：抗氧化劑是一種存在于食品中的能夠很好增強(qiáng)我們免疫系統(tǒng)的化學(xué)物質(zhì)。你可以靠服用一些抗氧化劑保健品來增強(qiáng)你的免疫功能： 醫(yī).學(xué)教育網(wǎng)整理

　　- Vitamin E 1000 IU per day. Alpha-tocopherol is the biological active form of vitamin E. There are two forms of it： d-tocopherol and dl-tocopherol. d- is the natural form and dl- is the synthetic form. Try to get the d- form because it is absorbed faster in our body.

　　- Vitamin C （ascorbic acid） 1000 milligram （mg） daily. Instead of taking supplement， you can take 2 pieces of citrus fruits （e.g. orange） a day to get the vitamin C

　　- Beta-carotene， not more than 10000 IU daily

　　- Selenium， 200 microgram daily

　　- Zinc， not more than 500 milligram （mg） daily

　　- Lipoic acid， 50 mg daily

　　- Glutathione， 50 mg daily

　　No any adverse effects have been reported from the above suggested supplementation dose.

　　——每天服用維他命E1000 IU （醫(yī)學(xué)國際單位，internatoinal units）。Alph-維生素E是一種生物活性維他命E.它有兩種形式：d-維生素E和dl-維生素E.d-維生素E是自然形式，dl-維生素E是合成形式。最好服用d-維他命E，因?yàn)樗梢愿斓谋晃覀兊纳眢w所吸收。

　　——每天1000毫克維他命C（抗壞血酸維生素C）。你也可以靠每天食用兩個(gè)柑桔類水果（例如桔子）來獲取維他命C.

　　——Beta胡羅卜素，每天服用不超過10000IU

　　——硒，每天200微克

　　——鋅，每天不超過500毫克

　　——硫辛酸，每天50毫克

　　——谷胱甘肽，每天50毫克

　　沒有任何人反映服用以上物質(zhì)有副作用。

　　2）

　　- Let green tea to be your daily beverage because it contains tremendous amount of antioxidant flavonoid， catechins.

　　- Eat more tomatoes， broccoli or fruits and vegetables in red and dark green color. They carry a huge amount of antioxidant carotenoids， lycopene and carotene.

　　——每天喝綠茶，因?yàn)榫G茶中含有大量抗氧化劑類黃酮和茶酸。

　　——多吃西紅柿，椰菜，和其它紅色和深色的水果。

　　3） No intense physical activities during this critical period！ It has been shown that intense exercise will suppress your immune function （related to the upper respiratory infection） even several days following your workout.

　　Instead of intense exercise， light-to-moderate workout helps if you have been training regularly.

　　在這段非常時(shí)期不要做劇烈運(yùn)動(dòng)！因?yàn)閯×疫\(yùn)動(dòng)會(huì)壓抑你的免疫系統(tǒng)功能（與你的上呼吸感染有關(guān)的免疫系統(tǒng)功能），并且此壓抑情況會(huì)持續(xù)好幾天。如果你以養(yǎng)成定期鍛煉的習(xí)慣，那么在這段時(shí)間你可以做一些輕度或中度運(yùn)動(dòng)。

　　4） Make sure you get enough carbohydrate foods （e.g. rice， food concentrated in starch…… etc） because carbohydrate is the primary food for immune cells . Do some Gatorade or Pocari if needed since they are both good sources of carbohydrate.

　　確保你食用足夠的碳水化合物食物（例如，大米及其它富含淀粉的食物），因?yàn)樘妓衔锸敲庖呒?xì)胞最重要的食物。喝一些Gatorade（一種飲料）或Pocari（一種飲料），因?yàn)樗麄兌际歉缓妓衔锏娘嬃稀?

　　5） Make sure you get enough sleep and don't make yourself so stressful！ Anxiety， depression， and tried will influence your body's stress hormones （e.g. catecholamine and glucocorticoids） and so suppress your immune status.

　　每天保證充足睡眠，不要使自己處于緊張和壓力之下。焦慮、緊張都會(huì)影響身體的壓力 荷爾蒙（例如，兒茶酚安和糖皮質(zhì)激素）從而壓抑身體免疫功能。

　　6） Mouth-mask helps despite it is not 100 effective. But it can still decrease the chance from infection.

　　口罩雖然不能100預(yù)防感染，但是能夠起到一定的作用，仍然可以減少被感染幾率。

　　All the above information are supported by peer-reviewed biomedical literatures， that means they are credible and reliable！ God bless and I really hope that none of you will get infected and I will pray for all of you in every moment！

　　以上所有信息均有生物醫(yī)學(xué)理論支持，這些建議都是不可思議和十分可靠的。上帝保佑。我真心希望你們中沒有一個(gè)人會(huì)被感染。我會(huì)時(shí)刻為你們大家祈禱平安！

　　Good luck and take extremely care.

　　祝你們好運(yùn)，千萬保重。
