Objective To examine the sleep status and relevant psychosocial factors in patients with colorectal cancer before surgery and improve their sleep quality. Methods A cross?sectional survey method was used. Participants were 107 cases of patients with colorectal cancer from the Department of Anorectal Surgery in The First Hospital ,which is affiliated with China Medical University. The Athens insomnia scale(AIS),Ham?ilton depression scale(HAMD),Hamilton anxiety scale(HAMA),perceived social support scale(PSSS),self?esteem scale(SES),medical cop?ing questionnaire(MCMQ),memorial University of Newfoundland scale of happiness(MUNSH),Eysenck personality questionnaire(EPQ),and Wong?Baker face scale were used to assess preoperative sleep in patients with colorectal cancer and related psychosocial factors. Results Among the 107 cases,there were 24 cases of insomnia,with an insomnia incidence of 22.43%. No statistical differences were found in demographic charac?teristics and clinical characteristics(P>0.05). According to the degree of insomnia,there were significant differences between groups(P<0.05) for depression,anxiety,social support,avoidance,yield,happiness,and EPQ?N. Before the surgery,the degree of depression,anxiety,and EPQ?P had a significant positive effect on the degree of insomnia (P< 0.05). Conclusion The degree of insomnia before surgery in patients with colorectal cancer is closely associated with depression,anxiety,coping styles,social support,and personality characteristics.

Objective:
To investigate the protective effect of ACY1215 (Rocilinostat), a histone deacetylase inhibitor, against brain edema in mice with acute liver failure.
Methods:
Lipopolysaccharide combined with D-galactosamine was used to establish a mouse model of acute liver failure, and ACY1215 was used for intervention. The effect of ACY1215 on histopathological changes of the liver was observed after 24 hours, as well as the changes in alanine aminotransferase (ALT), aspartate aminotransferase (AST), blood ammonia, tumor necrosis factor-α (TNF-α), interferon-γ (IFN-γ), brain water content, blood-brain barrier structure, NF-κB-p65, histone, acetylated histone, and TNF-α mRNA in brain tissue.
Results:
The mice with acute liver failure had marked pathological damage in liver tissue, as well as significant increases in the levels of ALT, AST, blood ammonia, TNF-α, and IFN-γ (

Objective:To establish a predictive model that can predict the effectiveness and safety of endoscopic surgery for pediatric upper urinary tract calculi, and evaluate its diagnostic efficacy through internal validation.Methods:The data was selected from the prospective database of pediatric upper tract calculi constructed by Beijing Friendship Hospital Affiliated to Capital Medical University from June 2014 to April 2019. A total of 348 children were recruited in this investigation including 250 boys and 98 girls, with a median age of 3.0 years(Interquartile Range 1.4, 7.0 years). Totally 375 endoscopic surgeries were performed, with an overall stone free rate (SFR) of 88.0% (330/375) and complication rate (CR) of 23.2% (87/375). This research used univariate and multivariate logistic regression analysis to evaluate and screen the predictors of SFR and CR. The nomogram of SFR and CR was established by using the selected predictive factors. The differentiation degree of the model was evaluated by the area under the curve (AUC), the consistency between the prediction probability and the actual risk was evaluated by the calibration curve, and the clinical benefits of the model application were assessed by the decision curve.Results:The results of multivariate analysis demonstrated that stone burden, operation duration, intraoperative perfusion, stone location and operative options were the postoperative predictors of SFR and CR for children. Besides, BMI was also a predictor of postoperative CR. The AUC of the model (model 1: SFR; model 2: CR) based on the above predictive factors was 0.81 and 0.73, respectively. The predictive probability of the calibration curve showed that the model had a good consistency with the actual value. The decision curve showed that the application of model 1 to predict SFR had significant clinical benefits when the threshold value was greater than 20%, and the application of model 2 to predict the postoperative CR had a significant clinical benefit when the threshold was greater than 10%.Conclusions:Nomogram based on stone burden, operation time, intraoperative perfusion, stone location and operative options was validated internally with preferable predictive power on the effectiveness and safety of pediatric endoscopic surgery. This model can be used to predict the clinical effects of pediatric endoscopic lithotripsy. BMI was also an important factor for the safety of pediatric endoscopic procedures.
