Like all other professionals, a doctor has an obligation to upkeep the standing of his or her profession. This can be achieved by

  1. continuously improving his or her professional skill,
  2. participating in the learning and teaching processes of continuing medical education, and
  3. engaging in medical research, at least at certain stage of his or her career such as while undergoing postgraduate training. Research runs in the blood of the academics and forms the backbone of the medical profession.

A major path for the Department has been clinical or applied research. Recent years has seen it moving into basic science research, and rightly so.

The Department also holds an annual research meeting (usually before Chinese New Year) aimed at allowing members of the Department, HKU and the community to find out what each other are doing in terms of research thus fostering collaborations and to give our trainees and students a chance to practice their presentation skills. Please visit the Medical Research Conference (MRC) homepage for further information.

For students wishing to undertake research degrees (e.g. PhD, MPhil) please refer to the Postgraduate page of Teaching and Training homepage.

Haematology, Medical Oncology & Bone Marrow Transplantation
The Division of Haematology, Medical Oncology & Haemopoietic Stem Cell Transplantation at Queen Mary Hospital is a tertiary / quaternary referral centre for blood diseases and malignant diseases in Hong Kong.

Range of clinical service
The Division comprises teams of experts in benign and malignant blood diseases, bone marrow transplantation and medical oncology. About 1000 new cases of these diseases are referred annually. The majority of these patients have haematological malignancies, consisting of acute and chronic leukaemias, lymphomas, plasma cell myeloma and other haematological neoplasms. Patients with other benign blood diseases including coagulation and bleeding disorders, acquired and inherited anaemias, and platelet disorders are also treated. The major facility for these patients is a specially designed haematology ward with HEPA-filtered air, which accommodates more than twenty patients.
The Division manages an adult haematopoietic stem cell transplantation suite, where more than a hundred allogeneic or autologous transplantations are performed every year. For allogeneic transplantation, this facility is the only one in Hong Kong. The full range of allogeneic transplantation is performed, with haematopoietic stem cells coming from HLA-identical siblings, matched unrelated donors and umbilical cord blood. Autologous transplantations are mainly performed for lymphomas and myeloma. The transplantation suite contains ten single rooms, a cytapheresis facility for isolation of peripheral blood haematopoietic stem cells, and a transplantation laboratory.
Medical Oncology is a relatively new development in the Division. Patients with a wide range of solid tumors are treated. Special emphasis has been placed on breast, liver and gastrointestinal cancers.

Clinical research
The Division is active in clinical research. Specific areas include new treatment protocols for acute leukaemias, malignant lymphomas and plasma cell myeloma; novel therapeutic approaches in patients with complications or relapses after haematopoietic stem cell transplantation; and thrombotic diseases. Predisposing factors and treatment of infective complications, including viral and invasive fungal infections, are also studied. Oral arsenic trioxide has been pioneered in the Division for the treatment of leukaemias and other haematological malignancies.
Medical Oncology research is focused on developing novel treatment strategies for various solid tumours, especially breast and gastrointestinal cancer. Early phase clinical trials are actively conducted to bring the novel therapeutics from the bench to the clinic.

Clinical trials
The Division conducts phase I, phase II and phase III clinical trials of novel therapeutic agents in benign and malignant blood diseases, and also solid tumors. These trials have included studies in coagulopathy, leukaemias, lymphomas, plasma cell myeloma and various solid tumors. Recruitment of patients is territory-wide, and cover all major hospitals in Hong Kong.

Basic research
The Division engages in basic research in the molecular genetic defects in haematological neoplasms, benign and malignant haematopoiesis, and solid tumors. For in vivo experiments, murine and zebrafish models are used. State-of-the-art technologies are utilized.

Specialist outpatient clinic
Patient referrals are seen in specialist outpatient clinics, which are listed below. Both Hong Kong residents and foreign patients are welcome. Private patients are also welcome, and appointments can be obtained from the Private Clinic at Queen Mary Hospital. Private patients can be admitted into specially designed private wards at Queen Mary Hospital, which include first class (single room) and second class (double room) suites.

Educational activities
Clinical fellows are welcome. Clinicians who want to conduct clinical work in Hong Kong need to check with the Hong Kong Medical Council on registration requirements. A knowledge of spoken Chinese is highly recommended, although not mandatory. Research laboratory fellows are accepted all year round. The Division also holds the following weekly meetings.

Infectious Disease
Internationally recognized landmark discoveries from the Infectious Diseases Division include, pioneering the application of topical TLR7 agonist imiquimod before intradermal influenza vaccination, which resulted in significantly higher and sustained antibody response, with protection against heterologous non-vaccine and antigenically drifted viruses; first to prove convalescent plasma and hyperimmune-IVIG reduced mortality, viral load and cytokine/ chemokine reaction in patients with severe influenza infection in a prospective cohort and a double-blind randomized controlled trial respectively; first to prove that clarithromycin, naproxen and oseltamivir combination reduce mortality and emergence of resistant quasispecies in the treatment of severe influenza infection; first to correlate disease severity with viral load from various specimens in SARS patients; first to demonstrate the potential toxicity and drug-drug interaction of colchicine with clarithromycin in a large case series.

These research findings have been published in top academic journals including the Lancet Infectious Diseases, Clinical Infectious Diseases, Emerging Infectious Diseases, Chest and Vaccine.

Research Interest

Systemic Lupus Erythematosus (PIs: Prof CS Lau & Dr. Vera SF Chan)

Our main research area is to study the immunobiology of systemic lupus erythematosus (SLE), a prototypic autoimmune disorder that predominantly affect young females. Immunologically, SLE is characterized by a loss of tolerance to self-antigens, T and B cell activation, and increased autoantibody production. Immune complex mediated vasculitis and specific antibody directed organ damage account for many of the clinical manifestations, however, the etiology of SLE remains unclear. Our team has previously identified phenotypic, functional abnormalities as well as the underlying mechanisms various immune cellular compartments in SLE patients. Through understanding the underlying causes of cellular and molecular immunodysregulation in SLE we aim to identify potential therapeutic targets for exploitation in clinical settings. Our current research projects focus on the following areas:

1) Inflammasome dysregulation in SLE (GRF-funded): a mechanistic study to dissect the role of a core immune component in SLE patients

2) Elucidation of the roles of regulatory non-coding RNAs in SLE: to explore the unidentified roles and mechanisms of regulatory RNAs in autoimmunity

3) Dissecting SLE disease heterogeneity by Omics technologies: a large scale research program to study lupus immunopathogenesis, teasing out pathogenic factors at the genetics, expression and cellular functional levels in correlation with patient stratification by clinical manifestations. It is a multidisciplinary research program, collaborating with geneticists, bioinformaticians and rheumatologists.

Spondyloarthritis (PI: Dr. Ho Yin Chung)
We have a broad scope of research in Spondyloarthritis (SpA) supported by the continuing enhancement of our collaborative research network. With the advancement of biologic therapies, researchers are looking for accurate imaging techniques for diagnosis and assessment in early disease. One of our research interests is the application of Magnetic Resonance Imaging (MRI) in SpA. Short tau inversion recovery (STIR) MRI sequence is traditionally used in assessing the extent of axial joint inflammation. However, despite its popularity, it provides little information on the intensity of inflammation. Our studies have shown that the apparent diffusion coefficient (ADC) of diffusion-weighted imaging MRI sequence correlates with disease activity, functional impairment and patient global assessment. Therefore, ADC may be used as an imaging marker for SpA. We are also looking at the correlations between ADC and several potential biomarkers.

Apart from imaging, we have been collaborating with The Hong Kong Society of Rheumatology and the Asia Pacific League of Associations (APLAR) SpA special interest group to collect data and evaluate the risks of various infections and comorbidities in patients with SpA. This will help improve the management of this disease in the future.
