  • Considerations and suggestions for standardizing clinical practice guideline of traditional Chinese patent medicine-chronic renal disease as an example

    The number of clinical practice guidelines for traditional Chinese patent medicine has been increasing recently. However, the quality of guidelines was still low compared to international guidelines. Considering the characteristics of traditional Chinese patent medicine, we suggested the following items should be taken into account when developing traditional Chinese patent medicine guidelines: ensuring the standardized guidelines of traditional Chinese patent medicine research problem is scientific based on reliable evidence; identifying the common questions according to these research problems; understanding the strength of evidence and how to recommend correctly; inviting some experts in other fields to take part in the development of guidelines; paying more attention on the changes of disease burden and the impact of new methods and technologies when developing the guideline; paying more attention to the non-consensus opinions and evidence supporting these opinions; insisting on quality is the priority, while speed is secondary.

  • Medicine+information: Exploring patent applications in precision therapy in cardiac surgery

    Currently, in precision cardiac surgery, there are still some pressing issues that need to be addressed. For example, cardiopulmonary bypass remains a critical factor in precise surgical treatment, and many core aspects still rely on the experience and subjective judgment of cardiopulmonary bypass specialists and surgeons, lacking precise data feedback. With the increasing elderly population and rising surgical complexity, precise feedback during cardiopulmonary bypass becomes crucial for improving surgical success rates and facilitating high-complexity procedures. Overcoming these key challenges requires not only a solid medical background but also close collaboration among multiple interdisciplinary fields. Establishing a multidisciplinary team encompassing professionals from the medical, information, software, and related industries can provide high-quality solutions to these challenges. This article shows several patents from a collaborative medical and electronic information team, illustrating how to identify unresolved technical issues and find corresponding solutions in the field of precision cardiac surgery while sharing experiences in applying for invention patents.
