Objective:To investigate the effect of early gradual diet on reducing delirium in elderly patients with hip arthroplasty.Methods:From January 2018 to January 2020, 74 cases of hip arthroplasty patients aged over 65 years old who were treated in the Third Affiliated Hospital of Sun Yat-sen University were selected as the observation objects. They were randomly divided into experimental group and control group with 37 cases in each group. The experimental group was given early gradual diet on the basis of routine postoperative care, while the control group was given routine postoperative diet on the basis of routine postoperative care. The incidence of postoperative delirium, Pittsburgh Sleep Quality Index (PSQI), patient satisfaction rate, average hospitalization days and average hospitalization expenses were used to evaluate the effect of early gradual diet on reducing delirium in elderly patients with hip arthroplasty.Results:The incidence of delirium in the experimental group was 2.70% (1/37) and 16.22% (6/37) in the control group, the difference was statistically significant ( χ2 value was 3.945, P<0.05); the hospitalization days of the experimental group were (10.68±5.13) d, (13.62±7.19) d in the control group. The difference of hospitalization days was statistically significant ( t value was 2.877, P<0.01). The incidence of difficulty in falling asleep and the satisfaction rate of the experimental group were 8.11% (3/37) and 94.59% (35/37) respectively, and those in the control group were 29.73% (11/37) and 78.38% (29/37) respectively, and the differences were statistically significant ( χ2 value was 5.638, 4.163, P<0.05). Conclusions:Early gradual diet after operation can reduce the incidence of delirium in elderly patients with hip arthroplasty, shorten the average hospitalization days, reduce the incidence of difficulty in falling asleep, improve patients' satisfaction, and help patients to pass through the perioperative period more safely and comfortably.

Objective To investigate the effect of COX6B2 expression in gastric cancer tissues on the patients'long-term prognosis and its underlying mechanism.Methods Based on the public databases and the medical records of patients,we analyzed the expression level of COX6B2 in gastric cancer and adjacent tissues and its influence on long-term prognosis of the patients.Enrichment analysis were used to predict the possible role of COX6B2 in gastric cancer.The effects of lentivirus-mediated COX6B2 knockdown on biological behaviors of gastric cancer cells were examined using CCK-8 assay,flow cytometry,and Western blotting.Results TCGA database and the results of immunohistochemistry,Western blotting and real-time PCR all demonstrated a significantly higher expression of COX6B2 in gastric cancer tissues(P<0.05).Kaplan-Meier plotter database and Kaplan-Meier curves showed that the patients with high COX6B2 expression had significantly shorter postoperative survival(P<0.05).A high expression of COX6B2 in gastric cancer tissues was closely correlated with clinicopathologic stage,CEA and CA19-9(P<0.05).A high expression of COX6B2,CEA level≥5 μg/L and CA19-9 level≥37 kU/L were independent risk factors affecting postoperative 5-year survival rate of gastric cancer patients(P<0.05),and COX6B2 expression level had a predictive value for long-term prognosis of the patients(P<0.05).GO and KEGG enrichment analyses showed that COX6B2 was mainly involved in the regulation of cell cycle.In the in vitro cell experiment,COX6B2 overexpression significantly promoted gastric cancer cell proliferation,increased the percentage of G1/S phase cells and inhibited the cellular expressions of p53 and p21(P<0.05).Conclusions COX6B2 is highly expressed in gastric cancer and is closely correlated with a poor long-term prognosis of the patients possibly by promoting gastric cancer cell proliferation and regulating cell cycle.
