自1956年成立以來,浸大已培育了逾131,000位畢業生,當中許多校友在各個領域都取得了顯著成就。我們期望讓校友擴闊知識領域,因此發掘來自不同專業領域的校友,並邀請他們分享有關方面的知識。
 
校友陳錦華博士從中醫角度分享糖尿病的知識

陳錦華校友 (中醫) 畢業於浸大,獲中醫學學士及生物醫學理學士,隨後於倫敦大學修讀公共衛生理學碩士、廣州中醫藥大學修讀中醫學碩士及香港大學修讀哲學博士(內科)等課程。於香港大學及瑪麗醫院專注臨床學術研究前,陳博士曾於下列不同大型機構服務:醫院管理局、世界衛生組織、東華三院及畢馬威顧問諮詢服務;並出任不同慈善組織及政府委員會的公職,積極推動中醫的發展。

他的臨床服務及研究證明中醫藥與維持糖尿病病人的腎臟功能有顯著的聯繫,中醫藥亦能有效地降低新冠肺炎患者的死亡率。

1. How common is diabetes in Hong Kong? Please list three key risk factors for diabetes.
   
  From the latest report of the Population Health Survey conducted between 2014-2015, 8.4% of the total Hong Kong population is estimated to have suffered from diabetes. Among them, 54.1% are undiagnosed.

Common symptoms include frequent thirst, frequent urination, frequent hunger, weight loss, fatigue, blurred vision, poor wound healing and itching skin. Nevertheless, these symptoms often are non-specific and diabetes in the early stage could be asymptomatic.

Key risk factors of diabetes include physical inactivity, aging, unhealthy diet, obesity, high blood pressure and family history. A large-scale study with 271,174 subjects published in 2018 shows that smoking is the strongest predictor of death among type 2 diabetes patients.
   
2. What is the cause of diabetes from the Chinese Medicine perspective? How does it compare with that from Western Medicine perspective?
   
  From the classics of Chinese Medicine, the presentation of diabetes is similar to Xiao-ke (消渴) and is one of the diseases developed among the obese population (膏人). The key pathophysiology involves congenital and environmental risk factors including stress, unhealthy diet, physical inactivity and obesity, all of which could cause accumulated heat and qi deficiency (氣虛).

In Western Medicine, diabetes involves beta-cell dysfunction, insulin resistance and gut microbiome dysbiosis, all of which could cause the glucose homeostasis imbalance, and induces oxidative stress and inflammation via multiple immunometabolic and signaling pathways.

The understanding of diabetes from Chinese Medicine and Western Medicine perspectives sounds different but indeed they are simply analysing diabetes from different perspectives: Chinese Medicine focuses on the epidemiological factors while Western Medicine puts emphasis on the molecular level. These understandings nowadays are increasingly crossing over with each other.
   
3. What treatment does Chinese Medicine provide for diabetes? How does Chinese Medicine work with Western Medicine?
   
  Chinese Medicine diagnoses and manages patients based on their symptoms. From our latest research, add-on symptom-based diagnosis improves the predictive power on kidney function decline among diabetic patients based on key biochemical and epidemiological factors. Presentation of edema, alternating dry and loose stool, epigastric bloating, thin tongue, deep pulse and unsmooth pulse are all associated with faster kidney function decline.

Chinese Medicine clinicians consider the pathogenesis from patients’ symptoms to personalise the prescription. For instance, if a patient shows predominantly symptoms that are associated with heat (e.g. dry mouth, frequent thirsty, red tongue, etc.), Chinese Medicines that clears heat (e.g. 桑葉, 枇杷葉) would be used. Whereas if a patient shows symptoms that are associated with weakened kidney, kidney-strengthening Chinese Medicines (e.g. 桑寄生, 地黃) would be used. Clinically patients are heterogenous, but we found that most diabetic patients in HK are either having qi-yin deficiency (氣陰兩虛) or dampness-heat.

Based on previous expert consensus and a pilot service programme, we started a service trial seven years ago aiming to evaluate the effect of Chinese Medicine on diabetic kidney disease. Our preliminary result shows that the service trial of using add-on rehmannia complex- (六味地黃丸) based Chinese Medicine prescription for 48 weeks helps the patients concerned better preserve their kidney function. An equally important observation is that fewer patients require increment in anti-diabetic drugs and there is a substantially lower risk of hypoglycemia, a common adverse side effect of concern, after taking Chinese Medicine.
   
4. Please provide three tips on preventing diabetes.
   
 
1. Healthy diet - low fat, low sugar, low sodium and high-fiber.
2. Physical exercise - exercise for at least 30 minutes for at least 5 days weekly.
3. Maintain a healthy body weight – normal range of body mass index (BMI) of Asians is 18.5 to 22.9.
BMI is a value derived from the mass (weight) and height of a person. The BMI is defined as the body mass divided by the square of the body height, and is expressed in units of kg/m2, resulting from mass in kilograms and height in metres.
