No. 385, 19.10.2011 9 CAMPUS NEWS 校 園 消 息 The hyphen, the en-dash and the em-dash The hyphen is a common punctuation mark used to connect two or more words to form a compound word: one-way state-of-the-art It should be noted that no plural noun should be used in such compound words: six-year-old (not six-years-old ) ten-dollar bill (not ten-dollars bill ) Sometimes, a hyphen is used to connect a short adverb and a verb to form an adjective: a well-taken point a much-admired speech However, if the adverb ends in –ly, no hyphen should be used: a poorly performed act a scientifically proven theory En-dashes and em-dashes are relatively lesser known, but professional editors and typographers should always observe the rules of their application. An en-dash (–), longer than the hyphen, is principally used to connect numbers and means ‘up to and including’: 20–25% the 2013–2015 triennium It can also be used to connect time and places: The National Day holiday is 1–7 October. The Queensway–Wanchai one-way fare is $4. The em-dash (—), the longest of the three, introduces or parenthesizes a phrase or clause which explains or qualifies the foregoing: The images of the tsunami stirred up what lies deep inside each of us— compassion for our fellow human beings. The triennium—which means a period of three years—is almost over.

Nowadays, oral antiviral drugs are very effective in suppressing the replication of hepatitis B virus (HBV). However, most patients experience relapse of hepatitis after stopping the antiviral drug. As doctors have little guidance on the timing of stopping medication, most patients are put on life-long treatment. Hepatitis B surface antigen (HBsAg) is a unique protein produced by HBV. Researchers at the Center for Liver Health at CUHK monitored 53 chronic hepatitis B patients who were treated by lamivudine for an average of three years. The researchers found that seven of the nine patients who achieved HBsAg of ≤100 IU/ml at the end of lamivudine treatment did not have a relapse one year after stopping medication, while relapse occurred in 42 of the 44 patients with HBsAg levels >100 IU/ml at the end of treatment. In conclusion, an HBsAg level of ≤100 IU/ml is a good predictor for disease control after stopping antiviral therapy. Therefore, CUHK recommends regular monitoring of serum HBsAg in chronic hepatitis B patients on antiviral drugs to decide when to stop therapy.  中大肝臟護理中心主任陳力元教授（右）及內科及藥物治療學系 黃煒燊副教授 Prof. Chan Lik-yuen Henry (right), director, Center for Liver Health; and Prof. Wong Wai-sun Vincent, associate professor, Department of Medicine and Therapeutics 中 華人民共和國第十一屆全國人民代表大會常務委 員會委員范徐麗泰博士應逸夫書院邀請，在10月 7日蒞臨中大，擔任書院聚會的嘉賓講者。她以「領導：情 為民所繫」為題，與一千四百名中大學生分享高見。  D r. the Honourable Rita Fan Hsu Lai-tai, member of the Standing Committee of the Eleventh National People’s Congress of the People’s Republic of China, shared her views on ‘Leadership: With the People, for the People’ with some 1,400 students at a Shaw College assembly on 7 October.
