Results The nutritional status showed no difference between two groups before treatment,and was significantly better in rhGH group after treatment.The healing time of autologous skin pulp grafting and donor site,the time of mechanical ventilation and the length of hospital stay were significantly shorter in rhGH group patients than control group.Conclusion rhGH can enhance the wound healing rate,improve the nutritional status of patients with mechanical ventilation,shorten the time of mechanical ventilation,and decrease the complications of burn.

Objective:Based on the detection of CD4+IL17+Th17 and CD4+CD25+Foxp3+Treg cells in the peripheral blood of patients with human papilloma virus (HPV), the study analyzes the ratio of Th17 to Treg and compares the different expression of cytokine IL-17, IL-10, TGF-β, and IL-23 in the serum. Methods:From September 2014 to June 2016, 119 cases of untreated patients with cervical HPV in-fection were collected at the First Affiliated Hospital of Xinjiang Medical University, which include 46 cases of cervical cancer (CC), 43 cases with cervical intraepithelial neoplasia (CIN)Ⅱ-Ⅲ, and 30 with chronic cervicitis (CCS). The detection of HPV types classified 80 patients as high-risk and 39 as low-risk. Flow cytometry examined Treg and Th17 cells, and enzyme-linked immune sorbent assay was used to test related cytokines. Results:In the infection of high-risk cervical HPV, the rate of the CC group was 87%(40/46), which was higher than that of the CINⅡ-Ⅲgroup and the CCS group, which were 77%(33/43) and 23%(7/30), respectively. For the expression of Th17 and Treg cells in the peripheral blood and the related cytokine IL-17, IL-23, TGF-β, and IL-10 in the serum, the levels of CC group were also significantly higher than that of the other two groups, and the ratio of Th17 to Treg increased considerably with the se-verity of cervical lesions. The expression of Th17 and Treg cells in the peripheral blood of patients with high-risk cervical HPV were higher than that of patients with low-risk cervical HPV (P<0.05), which was the same for the expression of the related cytokine IL-17, IL-23, TGF-β, and IL-10 in the serum. The ratio of the Th17 to Treg of patients with high-risk cervical HPV increased remarkably (P<0.05). Conclusion:The expression of Treg and Th17 cells in high-risk patients exhibits an increasing trend, and the ratio of increased Th17 to Treg may directly participate in the process of HPV infection and immune evasion, which plays an important role in the occurrence and development of cervical cancer.
