[Advances in the research of application of artificial intelligence in burn field].
Artificial intelligence has been able to automatically learn and judge large-scale data to some extent. Based on database of a large amount of burn data and in-depth learning, artificial intelligence can assist burn surgeons to evaluate burn surface, diagnose burn depth, guide fluid supply during shock stage, and predict prognosis, with high accuracy. With the development of technology, artificial intelligence can provide more accurate information for burn surgeons to make clinical diagnosis and treatment strategies.

Review[Advances in application of clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated 9 system in stem cells research].
Gene engineering has attracted worldwide attention because of its ability of precise location of disease mutations in genome. As a new gene editing technology, clustered regularly interspaced short palindromic repeats (CRISPR)/CRISPR-associated 9 (Cas9) system is simple, fast, and accurate to operate at a specific gene site. ⋯ Therefore, it has great significance to combine stem cells with the rapidly developing gene manipulation techniques. In this review, we mainly focus on the mechanism of CRISPR/Cas9 technology and its application in stem cell genomic editing, so as to pave the way for promoting rapid application and development of CRISPR/Cas9 technology.

[Influencing factors and clinical significance of severe hypocalcemia in patients with extremely severe burns in early stage].
Objective: To analyze the influencing factors and clinical significance of severe hypocalcemia in patients with extremely severe burns in early stage. Methods: Clinical data of 142 patients with extremely severe burns admitted to our wards from January 2010 to July 2015, conforming to the study criteria, were retrospectively analyzed. (1) The incidence of hypocalcemia and severe hypocalcemia on admission were calculated. (2) Patients were divided into the male group (n=113) and the female group (n=29) according to gender. The levels of serum calcium of patients whose age more than 55 years old and less than or equal to 55 years old in the two groups were compared with t test. (3) Patients were divided into severe hypocalcemia group (n=52) and non-severe hypocalcemia group (n=90) according to the level of serum calcium on admission. ⋯ Compared with non-severe hypocalcemia patients, patients with severe hypocalcemia are with larger total burn area, higher proportion of inhalation injury, later admission time, and lower albumin level on admission. However, only the albumin level on admission is the independent influencing factor of severe hypocalcemia in patients with extremely severe burns. And the level of serum calcium on admission can not predict the prognosis of patients with extremely severe burns.

[Dynamic variation trend and prognostic value of bronchial wall thickness in severely burned patients combined with inhalation injury].
Objective: To explore the dynamic variation trend of bronchial wall thickness (BWT) in severely burned patients combined with inhalation injury, and to determine the value of BWT to prognosis of patients. Methods: Forty-three severely burned patients with inhalation injury hospitalized in Intensive Burn Department of the Affiliated Hospital of Nankai University (Tianjin No.4 Hospital) from July to November 2016, conforming to the study criteria, were divided into survival group (n=27) and death group (n=16) according to the prognosis of patients within 14 days after admission. All patients underwent fiberoptic bronchoscopy and inhalation injury rating based on abbreviated injury scale at admission. ⋯ Grade 1.5 and 2.75 mm were respectively chosen as the optimal threshold values of inhalation injury rating at admission and BWT at admission, with sensitivity of 87.50%, 83.33% and specificity of 77.78%, 96.00%, respectively. Conclusions: The BWT of survived and dead patients with severe burn and inhalation injury increases significantly post burn, while the BWT of survived patients restores to normal level faster. BWT can be used to assess the severity of inhalation injury and to predict death in severely burned patients combined with inhalation injury.

[Antiseptic effect of compound lysostaphin disinfectant and its preventive effect on infection of artificial dermis after graft on full-thickness skin defect wound in rats].
Objective: To study the antiseptic effect of compound lysostaphin disinfectant and its preventive effect on infection of artificial dermis after graft on full-thickness skin defect wound in rats. Methods: (1) Each one standard strain of Klebsiella pneumoniae, Acinetobacter baumannii, and Staphylococcus aureus were selected. Each 20 clinical strains of Klebsiella pneumoniae, Acinetobacter baumannii, and Staphylococcus aureus were collected from those isolated from wound exudates of burn patients hospitalized in our wards from January 2014 to December 2016 according to the random number table. ⋯ Saturation of absorption of compound lysostaphin disinfectant achieves in artificial dermis after 2 hours' soaking. After 24, 36, and 48 hours' standing, the soaked artificial dermis still has the antibacterial effect on Klebsiella pneumoniae, Acinetobacter baumannii, and Staphylococcus aureus, respectively. The infection rate and the bacteria content of full-thickness skin defect wound in rats are all decreased when grafted with soaked artificial dermis.
