UM holds science popularisation talks to broaden high school students’ horizons in science
澳大辦科普講座拓寬中學生科學視野
在澳門大學健康科學學院成立10周年之際,該學院副教授譚建業及研究助理教授李蓓分別到新華學校向超過300位學生主講“製藥世紀:百年藥物開發”及“身體的荷爾蒙平衡”的講座,從而進一步豐富其學習生活及拓寬科學視野。
譚建業指出,醫學的進步建基於藥物的開發,把新藥物應用於臨床實踐,對人類生存起到關鍵作用。他提到從開發新藥物到上市之路是一個非常漫長和艱辛的旅程,包括基礎研究、藥物發現、臨床測試、人體臨床試驗,以及獲得相關監管機構的批准等。譚建業認爲,醫學革命都是前人傑出的成就,並為後人奠下了成功的基石。
此外,譚建業還談到新興科技與藥物開發的關係。藥物發現和開發不僅需要依靠DNA測序儀,還要使用搜集和分析各種遺傳基因組信息的新工具。他以第一個從成年細胞克隆出來的哺乳動物——克隆羊多利為例,其誕生為生物學和藥學帶來了許多可能性。在講座中,學生提出了有關基因編輯技術風險的問題,譚建業回答指,基因編輯相關技術總被認為如潘朵拉盒子一般,開啟了各種可能的同時存著各種的困難與風險,需要科學家去克服。
李蓓博士向學生介紹了荷爾蒙在人體中的重要性。她表示,荷爾蒙在身體的日常運作佔有重要的位置,血糖、血壓、生長、生育、生殖、新陳代謝等不同方面都受到荷爾蒙的影響,一旦缺乏或不均衡,便會出現內分泌失調。她以肥胖為例,指出胰島素作為人體一種重要的荷爾蒙,有助於調節碳水化合物和脂肪的代謝,降低餐後血糖,但在肥胖症中,病人往往是胰島素信號丟失。學生紛紛表示不想受到荷爾蒙的任意擺佈,影響身體的健康及生活質素。李蓓強調,大多數人靠均衡的飲食及健康的生活習慣便足以平衡身體內的荷爾蒙,如服用優質的維生素也可平衡體內荷爾蒙。
講者深入淺出地分享生物醫藥世界的奥妙,內容精彩豐富。他們更鼓勵學生勇敢追尋自己的科學夢,以開放的心態,不為自己設上限,在科學上邁出“第一步”,從而改變世界。

UM holds science popularisation talks to broaden high school students’ horizons in science
On the occasion of the tenth anniversary of the University of Macau (UM) Faculty of Health Sciences (FHS), Associate Professor Tam Kin Yip and Research Assistant Professor Li Bei in the FHS gave talks on ‘Pharmaceutical Century – Ten Decades of Drug Discovery’ and ‘Body Chemistry Balance’, respectively, to over 300 students at Xin Hua School to enrich their knowledge and broaden their horizons in science.
Prof Tam pointed out that medical advancement relies on drug development, and the application of new drugs in clinical practice is pivotal to the well-being of humanity. According to him, the process from developing a new drug to launching it to market is a long and arduous one, which involves basic research, drug discovery, preclinical testing, clinical trials on humans, and approval by the relevant regulatory authorities. He added that medical revolutions are the result of the outstanding achievements of the predecessors and are the foundations for the success of future generations.
In addition, Prof Tam talked about the relationship between emerging technologies and drug development. Drug discovery and development depend not only on DNA sequencers, but also on new tools for collecting and analysing genetic and genomic information of all kinds. He gave the example of Dolly the sheep, the first mammal cloned from an adult cell, whose birth opened up many new possibilities for biology and pharmacy. During the talk, some students asked questions about the risks of gene editing, to which Prof Tam replied that gene-editing technologies are still seen as Pandora’s box that opens up all sorts of possibilities, and at the same time, presents various difficulties and risks that scientists have to overcome.
Prof Li told the students about the importance of hormones in the human body. According to her, hormones play a crucial role in the daily operation of the body, influencing various aspects such as blood sugar, blood pressure, growth, fertility, reproduction, metabolism, and more. She also pointed out that if there is a deficiency or imbalance, endocrine disorders occur. Taking obesity as an example, she said that insulin, an important hormone in the body, helps regulate carbohydrate and fat metabolism and lowers postprandial blood sugar levels. However, insulin signals are lost in most patients with obesity. The students said that they do not want their health and quality of life to be affected by endocrine disorders, to which Li stressed that most people can balance their hormones through a balanced diet and a healthy lifestyle, and taking quality vitamins is also a good way to balance hormones in the body.
The speakers shared scientific knowledge in an entertaining and informative manner. They also encouraged the students to develop an interest in science, keep an open mind, and overcome self-imposed limitations, so that one day they can change the world with science and technology.
