ABSTRACT
Objective:To analyze the anatomical distribution of complex facial injuries (woun-ds ≥8 cm in length and involving two or more anatomical areas) in children, and to explore the effect of plastic and aesthetic surgery.Methods:A total of 157 children with complex facial injury were admitted to the Plastic Surgery Department of Hangzhou Plastic Surgery Hospital from January 2019 to June 2021, including 94 males and 63 females, aged from 2 to 18 years, with an average age of 6.2 years. The wound length was 8-20 cm, with an average length of 10.3 cm. Plastic surgery techniques were used to design different primary repair schemes according to specific wound conditions, and early postoperative scar prevention and treatment were carried out.Results:In 157 cases, 331 anatomical areas were involved, most of which were buccal (75 sites). The injury caused by sharp instruments (glass, ceramic tile, cutting tools, etc.) ranked the first place with 78 cases. All patients were followed up for more than 3 months, and the results showed 146 cases of primary healing, 11 cases of delayed healing, 8 cases of scar hyperplasia, 149 cases of good morphological and functional recovery.Conclusions:The advantages of using plastic and cosmetic surgery techniques to treat complex facial injuries lie in the emphasis on anatomical and functional reduction and tension-reducing suture, combined with a variety of postoperative scar prevention and treatment measures, and the results are satisfactory.
ABSTRACT
China's energy supply becomes more serious nowadays and the development of bio-energy becomes a major trend. Large oil companies have superb technology, rich experience and outstanding talent, as well as better sales channels for energy products, which can make full use of their own advantages to achieve the efficient complementary of exist energy and bio-energy. Therefore, large oil companies have the advantages of developing bio-energy. Bio-energy development in China is in the initial stage. There exist some problems such as available land, raw material supply, conversion technologies and policy guarantee, which restrict bio-energy from industrialized development. According to the above key issues, this article proposes suggestions and methods, such as planting energy plant in the marginal barren land to guarantee the supply of bio-energy raw materials, cultivation of professional personnel, building market for bio-energy counting on large oil companies' rich experience and market resources about oil industry, etc, aimed to speed up the industrialized process of bio-energy development in China.
