The serum levels of calcium of patients in severe burn group on PID 1, 7, 14, and 21 were significantly lower than the level of volunteers in healthy control group (Z=-2.375, -3.455, -2.442, -2.016, P less then 0.05 or P less then 0.01). Conclusions The serum osteoprotegerin, RANKL, RANKL/osteoprotegerin ratio, and PTH are increased, and the serum 25 hydroxyvitamin D, albumin, and calcium are decreased in the early stage of severe burn patients, which may be the mechanism leading to bone loss in patients.Objective To investigate the influence of silver ion dressing on related infections induced by inserted central venous catheter through wounds in patients with severe burn. Methods From June 2017 to December 2018, 90 severe burn patients who were admitted to the First Hospital of Hebei Medical University and met the inclusion criteria were included in this prospectively randomized control study. According to the random number table, they were divided into silver ion dressing group (30 patients, 20 males and 10 females, aged (37.2±3.4) years), sterile dressing group (30 patients, 18 males and 12 females, aged (35.2±4.1) years), and Anerdian dressing group (30 patients, 17 males and 13 females, aged (36.3±2.6) years). After admission, the patients in three groups were treated with a 16 G single-lumen central venous catheter inserted into the subclavian vein of burn wounds, with the depth of 19 cm. The puncture points of the patients in silver ion dressing group, sterile dressing group, and Anerdian dressing groignificantly shorter than the days in silver ion dressing group (P less then 0.01). (2) A total of 16 cases of CRBSI occurred in all the patients in 3 groups. A total of 16 pathogenic bacteria were isolated from catheter tip attachment microbial culture and blood microbial culture. The detections rates of pathogenic bacteria of patients in sterile dressing group
