Aim To deeply explore the experience of front‐line nurses who participated in rescuing Wuhan during the early stage of coronavirus disease 2019 (COVID‐19) epidemic. Methods Using a descriptive qualitative design, individual semi‐structured interviews were conducted between February 25 and March 5, 2020. A conventional content analysis method was used in data analysis to extract themes and sub‐themes. Results Six themes emerged after data analysis: (a) worries and stress during rescue; (b) difficulties encountered during rescue; (c) experience of team work; (d) experience of interaction with COVID‐19 patients; (e) experience of logistic support and widespread concern; and (f) value and significance of the experience. Conclusions Nurses took on difficult missions in the rescue and played an irreplaceable role. They experienced remarkable psychological changes over the intensive work. It was necessary to understand the feelings and problems of the nurses so as to establish a healthcare system that can protect medical staff effectively in future disasters.

Bowel preparation is a core issue in the quality of colonoscopy. We attempted to investigate whether an educational video via WeChat (a widely used mobile social media app) improved the compliance of patients and quality of bowel preparation. We enrolled 198 colonoscopy patients aged 35–70 years. They were randomly divided into the WeChat group (100 cases) and the control group (98 cases). The outcomes were the compliance of patients in the bowel preparation process and quality of the bowel preparation according to the Boston Bowel Preparation Scale. Participants' compliance increased markedly in the WeChat group compared with the control group (P < 0.01). The total Boston Bowel Preparation Scale score was significantly higher in the WeChat group than in the control group (7.02 ± 1.75 vs. 6.45 ± 1.91, respectively, p < .05). The intubation time (minutes) of colonoscopy in the WeChat group was shorter than that in the control group (7.38 ± 1.37 vs. 7.88 ± 1.39, respectively, p < .05). Our data confirmed that an educational video via WeChat can improve the quality of bowel preparation. It can also increase the compliance of bowel preparation and shorten the intubation time of colonoscopy.

Curcumin sensitizes human colon cancer in vitro and in vivo to radiation. Downregulation of LIG4 and PNKP and upregulation of XRCC5 and CCNH DNA-repair-related genes were involved in the radio-sensitizing efficacy of curcumin in colon cancer.
