功課，遊戲，課外活動
<<星期二檔案>> 自由玩
1. 啲細露學咁多野好有錢哩！其實點解唔自己教？家長自己識幾多？個小朋友學咁多野，講真，係為乜？
2. 老師教唔到就會用操功課等小朋友熟能生巧嘅把戲！點解會教唔到？可以係老師問題，亦可以係學校問題，或者係教育概念嘅問題！

Vaginal Intraepithelial Neoplasia (VAIN) 陰道上皮內瘤變 1
過了半年，即手術後身體完全康復的第一次陰道抹片驗查。結果陽性 — 低度病變 — 陰道上皮內瘤變 (vaginal intraepithelial neoplasia VaIN) [？]。與 CIN 一樣分3級。再做 HPV 驗查，依然 HPV33。 ...... 太罕見，不夠數量做有質量的數據。連醫生 (依然是譚家輝醫生) 都沒有甚麼建議。他提及一個病人，有癌，手術切除後依然低度病變；服用綠茶丸，病變清了。我說我不相信，他亦表示他也不相信。
我不吸煙，不喝酒，沒有做愛可能造成的反覆交叉感染。那只剩兩個可能性：
1. 長期用避孕丸 (接近 20 年)
2. 免疫系統有問題，就是無法清除此 HPV (這個醫生亦有表示過)
那避孕丸已停用了半年，或許要再給多點時間觀察。致於免疫力就這樣：
1. 先把時間表定好作 guideline 改掉壞習慣：
• 早睡早起
• 吃早餐及多喝水
• 一星期至少三日踏單車，亦把握多點與狗狗散步
因為有了時間表，溫習做 assignment 都能好好安排。有了安排就可減少壓力。
• 這些癌病與精神緊張很有關係。需放鬆，多做運動。我一有壓力，立刻有皮炎 (即濕疹)
• 不要太晚睡，少吃肉
• 改掉用護墊；白帶較多與難清 HPV 有關，特別氣味濃的。
先開藥使我減少白帶，戒掉用護墊，及使我安眠。下星期覆診 (Mar 5)。

3. 根據 American Cancer Society 一隻稱 imiquimod cream，本用提升受感染的部分的免疫力，可將 VAIN 2 / 3 降致 VAIN 1。有些女士甚而沒有 VAIN 了。不過此藥對 VAIN 的作用似乎還在硏究中。
按照時間表，晚餐要少肉 (可吃魚)。還可多吃蕃茄，紅燈籠椒，喝檸檬水。繼續看中醫調理一下亦無不可。到下一次驗查時，依然 positive 的話再咨詢醫生那個 imiquimod 可適合用。有了計劃，人安定許多！

Isn't Life Amazing?
Doctors Take A Long Shot And Inject HIV Into Dying Girl. The Reason Why Will Amaze You.
Scientists Have Made Old Mice Young Again
The fountain of youth may have been discovered after scientists found they could reverse the aging process in mammals.
Harvard researchers managed to turn the clock back for mice by helping their cellular DNA communicate more efficiently.
After just one week of restoring this communication scientists found two-year-old mice now had the body tissue of a six-month-old.
"In human years, this would be like a 60-year-old converting to a 20-year-old in these specific areas," said Professor David Sinclair, an expert in genetics at Harvard Medical School.
Researchers discovered that the nuclear DNA — found in the nucleus of a cell — and the Mitochondrial DNA — found in other parts of the cell — stop communicating as we age. Over time this loss of communication reduces the cell's ability to make energy, and signs of aging and disease become apparent.
"This particular component of the aging process had never before been described," said Dr Ana Gomes, a scientist in Sinclair's lab
The team found the communication problems were down to a depletion in a protein called NAD. When they upped the levels of NAD in the cells of mice, the ageing process reversed.
Prof Sinclair added: "The ageing process we discovered is like a married couple — when they are young, they communicate well, but over time, living in close quarters for many years, communication breaks down.
"And just like with a couple, restoring communication solved the problem. There's clearly much more work to be done here, but if these results stand, then many aspects of ageing may be reversible if caught early."
His team are now looking at the longer-term outcomes of the NAD-producing compound in mice and how it affects the mouse as a whole.
They are also exploring whether the compound can be used to safely treat rare diseases or more common diseases such as Type 1 and Type 2 diabetes. Longer term, the professor plans to test if the compound will give mice a healthier, longer life.
They also discovered that a molecule which switches on during ageing also switches on during cancer, in a finding that could improve treatments for the disease.
"We're starting to see now that the physiology of cancer is in certain ways similar to the physiology of aging," said Dr Gomes. "Perhaps this can explain why the greatest risk of cancer is age. "
The findings were published in the journal Cell.

What Is Justice?
我經常問我的學生 "What is justice?"
這個問題可能每個人都有不同的定義。所以，他們一聽到我問 "What is justice?" 他們便像「蟻咬」！
我想 justice 就是『己所不欲，勿施於人』。這簡單得小朋友也明白的道理，卻也有不簡單的情況。若有些行為是我不介意，別人卻在意呢？...... ooops!

人乳頭狀瘤病毒(HPV)疫苗 -- Gardasil
Girls, if affordable, you should always try to get maximum protection whenever you can. Your doctors may not recommend you to take Gardasil (HPV vaccine) because reports about the effectiveness of the vaccine shows that the older you are, the less effective the vaccine. BUT, say, a 20% effectiveness IS still better than no protection (0%). Unless there is a better alternative -- no sex. That's kinda like "don't blink". The love glove (condom) is only 30-40% effective. Well, you can try never open your eyes. Yes, it is rare that the HPV develops to cancer, but if it does, would you have regretted not to have taken the vaccine? Because today there is no cure for HPV caused cancer, only treatment -- which is to cut out the infected parts. How many body parts are you willing to get cut for not taking the vaccine? You do the maths.
Besides the vaccine can help you remove a bundle of other STDs!
女士們，如果負擔得起，你應該盡力得到最大保護。你的醫生可能不建議您採取 Gardasil（HPV疫苗），因為報告顯示疫苗有效性隨著年齡下降。但是，假設有效性只有20％仍比無保護（0％）為佳。除非有更好的選擇 - 沒有性活動。這有點像“不眨眼”。那麼，你可以嘗試從來不睜開眼睛。避孕套只有大慨 30-40% 效用。人乳頭狀瘤病毒發展到癌是小數，而且需時很長。但如果真的患上子宮頸癌時，你會否後悔當初沒有採用疫苗？因為今天沒有治愈HPV引起的癌症，唯一的治療方法是切出受感染的部位。你有多少身體部位願意被砍掉只為不用疫苗？你自己計計算。
除了子宮頸癌，疫苗可幫助除去一系列其他性病！

香港學生 • 香港老師
香港學生：
只要能打機便能不做功課。
即使不能打機，依然不會做功課。
但願所有功課都只不過是打機！
香港老師：
只要除消各種無謂的考試，老師便能真正施教，學生才能學真正的學問！
即使再多考試，依然不會令學生變得有見識。
但願學校可以變回學習的地方，而不是考試的地方！
