文摘Chinese medicine has been used for centuries to treat a range of health conditions.This history has produced a wealth of classical literature,case studies and clinical research data detailing its use and effectiveness.However,high-quality and conclusive evidence that meets modern requirements for clinical decision support is lacking.This evidence gap limits the integration of Chinese medicine with contemporary medicine,which in turn limits global access and acceptance of Chinese medicine as a form of safe and effective health care.Over the past 20 years,researchers and organisations around the world,including the World Health Organization(WHO)and United Nations,have worked to support the integration of traditional medicines,such as Chinese medicine,with conventional medicines to improve global health care.This paper provides an overview of Chinese medicine studies published in the top four general medical journals(BMJ,JAMA,Lancet and New England Journal of Medicine)from February 2005 to February 2024 in the past 20 years to highlight the progress in the development of this evidence base.It also highlights key actions taken to promote evidence-based clinical Chinese medicine,including product and practitioner regulation,formalising education standards,and international collaborations.Research conducted at the China-Australia International Research Centre for Chinese Medicine demonstrates the benefits of such a collaboration.Through development of its unique and inclusive‘whole-evidence’approach,plus clinical studies and systematic reviews,the Centre has significantly contributed to the evidence base for clinical Chinese medicine.In addition,its high-impact papers and groundbreaking monographs have been cited in international conventional medicine guidelines.While progress has certainly been made during the past 20 years to build a stronger evidence base for clinical Chinese medicine,there is still a considerable gap that limits its integration with conventional medicine.Future funding and research are needed to continue this work and achieve to safe,effective and accessible traditional medicine as part of the WHO’s Universal Health Coverage strategy.

文摘The disposal of contaminated water from Japan’s Fukushima nuclear power plant is a significant international nuclear safety issue with considerable cross-border implications.This matter requires compliance not only with the law of the sea but also with the principles of nuclear safety under international law.These principles serve as the overarching tenet of international and China’s domestic nuclear laws,applicable to nuclear facilities and activities.The principle of safety in nuclear activities is fully recognized in international and domestic laws,carrying broad legal binding force.Japan’s discharge of nuclear-contaminated water into the sea violates its obligations under the principle of safety in nuclear activities,including commitments to optimum protection,as low as reasonably practicable,and prevention.The Japanese government and the International Atomic Energy Agency(IAEA)have breached the obligation of optimum protection by restricting the scope of assessments,substituting core concepts,and shielding dissenting views.In the absence of clear radiation standards,they have acted unilaterally without fulfilling the obligation as low as reasonably practicable principle.The discharge of Fukushima nuclear-contaminated water poses an imminent and unpredictable risk to all countries worldwide,including Japanese residents.Japan and the IAEA should fulfill their obligations under international law regarding disposal,adhering to the principles of nuclear safety,including optimum protection,the obligation as low as reasonably practicable,and prevention through multilateral cooperation.Specifically,the obligation to provide optimum protection should be implemented by re-evaluating the most reliable disposal technologies and methods currently available and comprehensively assessing various options.The standard of the obligation as low as reasonably practicable requires that the minimization of negative impacts on human health,livelihoods,and the environment should not be subordinated to considerations of cutting costs and expenses.Multilateral cooperation should be promoted through the establishment of sound multilateral long-term monitoring mechanisms for the discharge of nuclear-contaminated water,notification and consultation obligations,and periodic assessments.These obligations under international law were fulfilled after the accidents at the Three Mile Island and Chernobyl nuclear power plants.The implications of the principles of nuclear safety align with the concept of building a community of shared future for nuclear safety advocated by China.In cases of violations of international law regarding the disposal of nuclear-contaminated water that jeopardize the concept of a community of a shared future for nuclear safety,China can also rely on its own strength to promote the implementation of due obligations through self-help.
