Objective:To study the timeliness incentive nursing intervention applied to rectal cancer postoperative rehabilitation of colostomy.Methods:A total of 120 cases of permanent rectal cancer patients who were treated with colostomy in Dalian University affiliated Xinhua Hospital during February 2016 to February 2019 were evenly divided into observation group and control group by random number table method. The control group were caught out by conventional postoperative rehabilitation nursing. The control group were caught out by the timeliness incentive nursing intervention. Two groups of patients were compared before and after continuous care for 3 months in many ways which included the pain degree, the time to get out of bed, the time of first eating, length of hospital stay, negative emotions, compliance, self-management ability and postoperative complications.Results:The pain degree, the first activity time away from the bed, the first time to eat and the hospital stay were 1.9±0.5, (14.36±2.43) h, (21.39±3.08) h, (8.78±0.82) d in the observation group, and 3.5±1.1, (20.02±2.97) h, (27.14±3.96) h, (11.01±1.43) d in the control group. The difference was statistically significant ( t values were 5.369- 9.539, P<0.05). The negative emotions such as anxiety and depression in the observation group scored 41.4±2.3 and 39.9±2.0 after nursing. However, the control group scored 47.6±3.8 and 45.9±2.2 after nursing, respectively. The difference was statistically significant ( t values were 3.509, 3.519, P<0.05). The self-management abilities of patients in the observation group, including emotional cognition management, general life management, disease cognitive management and colostomy nursing management were 23.43±2.12, 24.04±0.96, 23.02±3.22, and 21.43±1.75, significantly higher than those in the control group (18.96±2.82,18.89±1.69, 17.95±2.61, 16.87±2.12). The difference was statistically significant ( t values were 17.712-18.879, P<0.05). The compliance of the observation group in nursing, rehabilitation and reexamination was 0.79±0.19, 0.98±0.23 and 0.87±0.35, significantly higher than those of the control group (1.02±0.26, 1.58±0.36, 1.46±0.43). The difference was statistically significant ( t values were 5.532, 5.221, 5.645, P < 0.05). The incidence of postoperative complications in the observation group was significantly lower than that in the control group. The incidence of observation group was 8.33% (5/60), and the incidence of control group was 23.33% (14/60). The difference was statistically significant ( χ 2 values were 5.065, P<0.05). Conclusions:Timeliness incentive can obviously shorten the postoperative recovery time of colostomy patients in getting out of bed and capacity to eat, length of hospital stay. It can relieve the postoperative pain and the negative emotions, and also improve compliance and relieve self-management ability, and reduce the occurrence of postoperative complications.

Objective:To explore the effects of enriched environment combined with melatonin on learning and memory function and DNA oxidative damage in senescence accelerated mouse prone 8 (SAMP8) mice.Methods:Twenty-four 6-month-old SPF healthy male SAMP8 mice were randomly divided into model group, enriched environment group, melatonin group and enriched environment+ melatonin group, with 6 mice in each group. Six homologous SAMR1 mice of the same age were used as the control group. The mice in the enriched environment group and the enriched environment+ melatonin group were fed in the enriched environment. At the same time, the mice in the melatonin group and the enriched environment+ melatonin group were subcutaneously injected with melatonin (8 mg /(kg·d)) once a day for 28 d. The mice in the model group, the control group and the enriched environment group were subcutaneously injected with an equal volume of 0.9% sodium chloride solution once a day for 28 days. Aging score was used to evaluate the aging of mice. Morris water maze and Y maze tests were used to evaluate the learning and memory ability of mice. The cell morphology of hippocampus in mice was observed by hematoxylin-eosin staining, and the level of Aβ 1-42 protein in hippocampus of mice was detected by immunohistochemical staining. The levels of γ-H2A histone family member X(γ-H2AX) and 8-hydroxy-2 deoxyguanosine(8-OHdG) proteins in hippocampus of mice were detected by Western blot and Enzyme-linked immunosorbent assay. SPSS 25.0 statistical software was used to process the data. One-way analysis of variance was used for comparison among multiple groups, and LSD- t test was used for further pairwise comparison. Results:(1)There was a statistical difference in aging scores among the 5 groups of mice after intervention ( F=126.4, P<0.01). After intervention, the aging scores of mice in the enriched environment group, melatonin group, and enriched environment+ melatonin group were lower than that in the model group (all P<0.05), and the score of the enriched environment+ melatonin group was significantly lower than that in the enriched environment group ( P<0.05). (2)The time and group interaction, group main effect and time main effect of the escape latency among the 5 groups of mice were statistically significant ( F=11.2, 799.9, 121.8, all P<0.01). From day 2 to day 4, the escape latencies of mice in the enriched environment group, melatonin group and enriched environment+ melatonin group were significantly lower than that in the model group (all P<0.05). There was a statistically significant difference in the target quadrant residence time and cross-platform times among the 5 groups ( F=70.38, 48.83, both P<0.01). The target quadrant residence time and cross-platform times of mice in the enriched environment group, melatonin group, and enriched environment+ melatonin group were significantly higher than that in the model group (all P<0.05). (3) There were significant differences in the total number of alternations and correct rates among the 5 groups ( F=291.328, 113.482, both P<0.01). The total numbers of alternations and correct rates in melatonin group ((29.46±3.75)times, (53.16±3.47)%) and the enriched environment+ melatonin group((32.57±3.52)times, (58.60±4.13)%)were significantly higher than those in the model group ((18.62±3.96)times, (43.61±3.92) %)(all P<0.05). (4)The results of hematoxylin-eosin staining and immunohistochemistry staining showed that compared with the model group, the cell structure and morphology of the hippocampus of mice in enriched environment group, melatonin group, and enriched environment+ melatonin group were significantly improved, and the expression of Aβ 1-42 was significantly reduced (all P<0.05). (5) There were statistically significant differences in the levels of γ-H2AX and 8-OHdG proteins in the hippocampus of the 5 groups of mice ( F=78.09, 117.20, both P<0.01). The levels of γ-H2AX and 8-OHdG of mice in the enriched environment+ melatonin group ((1.37±0.26), (4.79±0.35)pg/μg) were significantly lower than those in the enriched environment group ((2.83±0.25), (7.23±0.41)pg/μg) and the melatonin group ((2.43±0.22), (6.69±0.28)pg/μg) (all P<0.05). Conclusion:Both enriched environment and melatonin can significantly improve the learning and memory function of SAMP8 mice, and the combined treatment effect is more significant.The mechanism may be related to the reduction of DNA oxidative damage in hippocampus.
