As a powerful attempt by government to promote the construction of the multi-level healthcare security system and social and commercial integration in China, " City-customized Medical Insurance" still has many problems to be solved at the beginning of its development, such as unclear boundary between government and enterprises, limited coverage and strength of security. On the basis of clarifying the current situation of " City-customized Medical Insurance", and combing the management experience of social and commercial integration in Medicare Part C plan of the United States, the authors put forward that China should make full use of the advantages of the combination of promising government and efficient market, guide differentiated product design, and establish market access and evaluation mechanism, so as to promote the effective connection between China′s commercial health insurance and basic healthcare insurance, and further reduce the people′s medical burden.

Proteins and peptides have become a significant therapeutic modality for various diseases because of their high potency and specificity. However, the inherent properties of these drugs, such as large molecular weight, poor stability, and conformational flexibility, make them difficult to be formulated and delivered. Injection is the primary route for clinical administration of protein and peptide drugs, which usually leads to poor patient's compliance. As a portable, minimally invasive device, microneedles (MNs) can overcome the skin barrier and generate reversible microchannels for effective macromolecule permeation. In this review, we highlighted the recent advances in MNs-mediated transdermal delivery of protein and peptide drugs. Emphasis was given to the latest development in representative MNs design and fabrication. We also summarize the current application status of MNs-mediated transdermal protein and peptide delivery, especially in the field of infectious disease, diabetes, cancer, and other disease therapy. Finally, the current status of clinical translation and a perspective on future development are also provided.
