of NGTI group was significantly lower than that in NGFI group at PIH 2, 6 and 12 (P less then 0.05), and the concentration of HB-EGF in cell culture supernatant of SMGTI group was significantly higher than that in NGTI group at PIH 2 and 6 (P less then 0.05). Conclusions The proliferation and secretion functions and expression of wound repair related protein of human HaCaT cells inflicted with thermal injury in simulated microgravity environment showed complex and diversified changes, which provide theoretical basis for further research on damage repair under weightlessness.Objective To analyze the epidemiological characteristics and the related information on the diagnosis and treatment of inpatients with skin and soft tissue injuries. Methods The medical records of inpatients with skin and soft tissue injuries who were admitted to the Fourth Medical Center of PLA General Hospital (hereinafter referred to as the author's unit) from January 1, 2014 to December 31, 2018, conforming to the study criteria, were retrospectively analyzed. The indexes included inpatients'gender, age, wound course, underlying disease, wound type, wound site, and wound microbiological culture result, methods and outcome of treatment, type of medical payment, hospital day, and hospitalization cost. Data were statistically analyzed with Mann-Whitney U test, Kruskal-Wallis H test, and chi-square test. Results (1) A total of 2 997 inpatients, conforming to the study criteria, were admitted to the author's unit during the 5 years. There were 1 803 (60.16%) males and 1 194 (39.84%) females. The distribution ould adjust the consumption ratio and other management indicators according to the actual clinical needs of elderly patients with chronic wounds.Objective To compare the effects and characteristic difference of negative pressure materials of polyvinyl alcohol and polyurethane in the treatment of full-thickness burn wounds after escharotomy. Methods From January 2018 to December 2019, 60 patients with full-thickness burns who met the inclusion criteria and hospitalized in Xuzhou Renci Hospital were recruited in this prospective randomized controlled trial. According to the random number table, 60 cases were divided into polyvinyl alcohol group (n =30, 13 males and 17 females) and polyurethane group (n =30, 14 males and 16 females), aged (34±7) and (35±6) years respectively, with burn area of 4.20% (2.23%, 4.90%) total body surface area (TBSA) and 3.89% (2.18%, 4.76%)TBSA and escharectomy area of 2.70% (1.97%, 3.42%) TBSA and 2.87% (2.12%, 3.34%)TBSA, respectively. After patient's admission, debridement was immediately performed on the full-thickness burn wound, and the dressing was changed with iodophor once a day. Escharectomy was performed on post ins inflammatory edema and serious contamination. Polyvinyl alcohol foam material is less adherent to wounds, which is better than polyurethane foam material in the aspects of reducing wound bleeding and residual foreign body. Polyvinyl alcohol foam material can be firstly selected to fix and promote skin graft survival after skin grafting, wound bed preparation before skin grafting of burn with large area and deep wound cavity or sinus, etc. Both types of foam materials need to be improved in the aspects of bacterial colonization and prevention and treatment of skin eczema.Objective To investigate the effects of hypoxia-pretreated rat adipose-derived mesenchymal stem cells (ADSCs) conditioned medium on wound healing of rats with full-thickness defects. Methods (1) A 6-week-old male Sprague-Dawley rat was sacrificed by cervical dislocation, the bilateral inguinal adipose tissue was collected, the third generation ADSCs were isolated by collagenase digestion method, and the cells morphology was observed. The cells were harvested and divided into adipogenic induction group and osteogenic induction group according to the random number table (the same grouping method below), with 6 wells in each group. The cells
