Prevention of hypertrophic scar formation of the skin requires a complex treatment process, which mainly includes promoting skin regeneration in an early stage while inhibiting hypertrophic formation in a later stage. Electrospinning PLGA with the three-dimensional micro/nano-fibrous structure and as drugs carrier, could be used as an excellent skin repair(More)
Hypertrophic scarring (HS) has been considered as a great concern for patients and a challenging problem for clinicians as it can be cosmetically disfiguring and functionally debilitating. In this study, Ginsenoside Rg3/Poly(l-lactide) (G-Rg3/PLLA) electrospun fibrous scaffolds covering on the full-thickness skin excisions location was designed to suppress(More)
This study explores the implementation of the mandatory national college English curriculum within a Chinese tertiary context. Using a mixed methods approach, I conducted the study by engaging three groups of participants. I interviewed four national policymakers in terms of syllabi, textbooks, and tests to identify the intended curriculum. I interviewed(More)
BACKGROUND Intermittent external volume expansion using suction enhances the vascular network of soft tissues, possibly increasing fat graft survival. However, the optimal kinetics of application have not been determined. Based on their previous experience, the authors hypothesized that moderate-intensity intermittent external volume expansion application(More)
Incorporation of bioactive drugs and biofunctionalization of polyester fibrous scaffolds are essential means to improve their bio-functions and histocompatibility for regenerative medicine. However, it is still a challenge to biofunctionalize such drug carriers via traditional biochemical methods while maintaining their properties without changes in drug(More)
BACKGROUND Intra-lesional injections of corticosteroids, interferon, and chemotherapeutic drugs are currently the most popular treatments of hypertrophic scar formation. However, these drugs can only be used after HS is formed, and not during the inflammatory phase of wound healing, which regulates the HS forming process. OBJECTIVE To investigate a new,(More)
In order to make the strategy for research and development (R&D) purchase system better serve the personalization of material requirements in R&D process, the authors propose to develop a strategy set which will satisfy the internal as well as external constraints simultaneously. Social network analysis is used to analyze the vertical and horizontal(More)
Clinically, hypertrophic scarring (HS) is a major concern for patients and has been a challenge for surgeons, as there is a lack of treatments that can intervene early in the formation of HS. This study reports on a Chinese drug, 20(R)-ginsenoside Rg3 (GS-Rg3), which can inhibit in vivo the early formation of HS and later HS hyperplasia by inducing the(More)
BACKGROUND The author's goal was to present an approach for serial surgical reconstruction of anophthalmic orbits with 'bag-shaped' flaps and cartilage transplantation. METHODS A review was performed of 53 patients who underwent serial physiological orbital reconstruction between 2006 and 2013. Orbital reconstruction was performed serially in stages,(More)
