Abstract: Objective To study the clinical effect of photo rejuvenation on skin cosmetic treatment.

Methods A total of 200 patients with facial skin cosmetic who visited our hospital from December 2016 to October 2017 were divided into two groups according to different medical conditions: 78 cases of facial hyper pigmentation in group A, 80 cases of facial telangiectasia in group B Cases, C group facial aging, photo aging group of 62 patients, three groups were treated by photo rejuvenation, the clinical efficacy and cosmetic satisfaction of the three groups were observed and statistics. Results The three groups were followed up for 6 months after photo rejuvenation. The effective rate was 98.72% in group A, 92.5% in group B, 93.55% in group C. Satisfaction of three groups of patients satisfaction evaluation on cosmetic effect were: satisfaction rate of group A was 98.72%, satisfaction of group B was 87.50%, satisfaction of group C was 90.32%. Photo rejuvenation on the increase of facial melanoma, telangiectasia aging, the exact effect of photo-aging, patients with high satisfaction. Conclusion Photo rejuvenation treatment of skin beauty can significantly reduce the stain, improve skin texture, firm skin, shrink pores, with a significant cosmetic effect, it is worth promoting clinical efforts.

Abstract: Ultrafast and ultraintense lasers have ultrafast temporal and ultraintense focal intensity properties. They can create unprecedentedly extreme experimental conditions with ultrahigh time resolution, temperature, and pressure as well as ultrahigh-strength field. The ultrafast and ultraintense laser is one of the important tools for frontier fundamental research meant for extending the knowledge of mankind. This paper starts with the analysis of the application and development demands of the ultrafast and ultraintense lasers and then systematically investigates the research status of these lasers in China and abroad. Based on this, the developing routes and targets of ultrafast and ultraintense lasers as well as the related technologies needed for achieving these targets are proposed. Particularly, we proposed the respective key steps for developing ultraintense lasers with ultrahigh peak power and those with high repetition frequency, and emphasized the study of related technologies and ancillary components. Furthermore, several suggestions are proposed for the development of ultrafast and ultraintense lasers in China, including strengthening fundamental researches, improving personnel training, enhancing international cooperation, and promoting market application, hoping to provide references for the steady development of China’s laser technologies.

摘 要

近年来，由于人口老龄化的加剧，慢性创面患者数量不断增多。因其发病机制尚未研究清楚，治疗较困难，治疗方式多样化，无固定模式，应用许多药物的治疗效果不佳。本文以“TIME”原则为基点，将慢性创面创面床准备的研究进展予以综述，旨在为慢性创面的诊治提供新思路。

Abstract

In recent years, due to the aggravation of population aging, the number of chronic wound patients has continued to increase. Because the pathogenesis has not been clearly studied, the treatment is difficult, the treatment methods are diversified, and there is no fixed pattern. The treatment effect of many drugs is not good. Based on the “TIME” principle, this paper reviews the research progress of wound bed preparation for chronic wounds, aiming to provide new ideas for the diagnosis and treatment of chronic wounds.

Abstract

      Chromobacterium violaceum is a Gram negative, facultative anaerobe, generally present in water, soil in tropical and subtropical regions. This bacterium is an emerging environmental pathogen that causes life threatening infection in humans and animals. It can cause wound infection, visceral abscess, septicaemia, meningitis, diarrhoea, UTI. It is associated with significant mortality due to severe systemic infection. As the bacteria have high spreading tendency leading to sepsis, early identification and prompt treatment is necessary. Here we report a case of Chromobacterium violaceum wound infection in a 9 years old male from Dhaka, who was successfully treated with combination of cefixime and flucloxacillin antibiotics as per culture sensitivity report.
