Objective:To examine attentional bias and its characteristics of college students with different lev-els of self-esteem toward cyber-aggressive information versus cyber-neutral information in frustration situations.Methods:Totally 280 college students were selected,and 76 subjects in the high self-esteem group(27％of the top SES scores)and 76 subjects in the low self-esteem group(27％of the bottom SES scores)were screened with the Self-Esteem Scale(SES).A virtual intelligence test was used to manipulate the frustration situation,and two groups were subjected to a situation initiation with and without frustration,and completed a point-probe task to examine the attentional vigilance and attentional extrication difficulty components of the attentional bias of college students with high and low self-esteem in frustration situations.Results:In the frustration context,low self-esteem college students had shorter response times to cyber-aggressive words than to cyber-neutral words(P＜0.001),low self-esteem college students' attentional vigilance scores to cyber-aggressive words weregreaterthan0(P＜0.001),and there was no statistically significant difference in the scores of attentional dissociative difficulties to cyber-ag-gressive words between high and low self-esteem college students compared to 0(Ps＞0.05).Conclusion:Low self-esteem college students in frustration situations have a significant attentional bias toward cyber-aggressive infor-mation,mainly in the form of attentional vigilance.

Objective:To explore facilitators and impediments to home glucose management for patients undergoing bariatric surgery based on the consolidated framework for implementation research (CFIR), so as to inform the development of a glucose management pathway after bariatric surgery.Methods:This study was a descriptive phenomenological study. Using purposive sampling method, seven healthcare professionals and 11 patients undergoing bariatric surgery from the General Surgery·Metabolic and Bariatric Center of China-Japan Friendship Hospital were selected from November 2023 to January 2024 for semi-structured interviews. Targeted content analysis was used for the data analysis.Results:A total of six facilitators and six impediments related to the five dimensions of CFIR were distilled. Facilitators included the personalized glucose management program, regular long-term follow-up, multidisciplinary management team, support from family and friends, complication distress, and information technology platform. Impediments involved patterned follow-up, poor accessibility and convenience of resources, role conflict, herd mentality, poor behavioral compliance, and low utilization of digital equipment.Conclusions:Glucose management needs vary in patients after bariatric surgery, with a gradual decline in management compliance. Healthcare professionals should build an "Internet +"home glucose management service model, carry out targeted multidisciplinary team follow-up, and promote the formation of a standardized pathway for patients' home glucose management.

Objective To explore the mechanism of Wumei pill on ulcerative colitis(UC)in mice based on the anti oxidative stress pathway of nuclear factor erythroid 2-related factor 2(Nrf2)/antioxidant response element(ARE).Methods Seventy SPF male C57BL/6 mice were randomly divided into the control group,the UC group,the mesalazine group(MES group,0.82 g/kg MES),the low dose Wumei pill group(WMW-L group,5 g/kg crude drug),the middle dose Wumei pill group(WMW-M group,10 g/kg crude drug),the high dose Wumei pill group(WMW-H group,20 g/kg crude drug)and the high dose Wumei pills+Nrf2 inhibitor ML-385 group(WMW-H+ML-385 group,Wumei pills crude drug 20 g/kg+20 mg/kg ML-385),with 10 rats in each group.The disease activity index(DAI)score and colonic mucosa injury score were performed in mice after the last administration.Pathological changes of colonic mucosa in mice were observed by HE staining.The levels of interleukin(IL)-1β,tumor necrosis factor-α(TNF-α)and IL-6 in serum and colon tissue of mice were measured by enzyme-linked immunosorbent assay(ELISA).The content of malondialdehyde(MDA)in serum and colon tissue of mice was determined by thiobarbituric acid colorimetry(TBA).The activity of superoxide dismutase(SOD)in serum and colon tissue of mice was measured by xanthine oxidase method.The activity of glutathione peroxidase(GSH-px)in serum and colon tissue of mice was determined by direct method with dithiodinitrobenzoic acid(DTNB).The positive expression of Nrf2 in colon tissue of mice was observed by immunohistochemistry.The expression of heme oxygenase-1(HO-1)and NAD(P)H:quinone oxidoreductase-1(NQO1)proteins in colon tissue of mice were detected by Western blot assay.Results Compared with the control group,the DAI score,colonic mucosa injury score,colonic histopathology score,levels of IL-1β,TNF-α,IL-6 and MDA in serum and colonic tissue,and expression levels of Nrf2,HO-1 and NQO1 protein in colonic tissue of mice were increased in the UC group,levels of SOD and GSH-px in serum and colon tissue decreased(P＜0.05),the colon mucosa of mice was seriously damaged.Compared with the UC group,changes of corresponding indexes were contrary to the above in the MES group,the WMW-M group and the WMW-H group.However,the expression levels of Nrf2,HO-1 and NQO1 proteins in colon tissue were increased(P＜0.05),and the damage of colon mucosa in mice was alleviated.Changes of the above indexes were dose-dependent in the WMW-L group,the WMW-M group and the WMW-H group.There were no significant differences in the above indexes between the WMW-H group and the MES group.ML-385 attenuated the improvement effect of high dose Wumei pill on colon mucosa injury.Conclusion Wumei pill may alleviate the colon mucosal damage of UC mice by activating Nrf2/ARE antioxidant stress pathway.

Objective:To assess the effectiveness of a 6-month Ba Duan Jin exercise program in improving the balance of community-dwelling older adults.Methods:A two arms, parallel-group, cluster randomized controlled trial was conducted in 1 028 community residents aged 60-80 years in 40 communities in 5 provinces of China. Participants in the intervention group (20 communities, 523 people) received Ba Duan Jin exercise 5 days/week, 1 hour/day for 6 months, and three times of falls prevention health education, and the control group (20 communities, 505 people) received falls prevention health education same as the intervention group. The Berg balance scale (BBS) score was the leading outcome indicator, and the secondary outcome indicators included the length of time of standing on one foot (with eyes open and closed), standing in a tandem stance (with eyes open and closed), the closed circle test, and the timed up to test.Results:A total of 1 028 participants were included in the final analysis, including 731 women (71.11%) and 297 men (28.89%), and the age was (69.87±5.67) years. After the 3-month intervention, compared with the baseline data, the BBS score of the intervention group was significantly higher than the control group by 3.05 (95% CI: 2.23-3.88) points ( P<0.001). After the 6-month intervention, compared with the baseline data, the BBS score of the intervention group was significantly higher than the control group by 4.70 (95% CI: 4.03-5.37) points ( P<0.001). Ba Duan Jin showed significant improvement ( P<0.05) in all secondary outcomes after 6 months of exercise in the intervention group compared with the control group. Conclusions:This study showed that Ba Duan Jin exercise can improve balance in community-dwelling older adults aged 60-80. The longer the exercise time, the better the improvement.

Alzheimer's disease(AD)is a prevalent neurodegenerative disease characterized by cognitive decline in the early stage.Mild cognitive impairment(MCI)is considered as an intermediate stage between normal aging and AD.In recent years,studies related to resting-state functional MRI(rs-fMRI)indicated that the occurrence and development process of MCI and AD might be closely linked to spontaneous brain activity and alterations in functional connectivity among brain regions,and rs-fMRI could provide important reference for specific diagnosis and early treatment of MCI and AD.The research progresses of rs-fMRI for MCI and AD were reviewed in this article.

Objective To investigate the incidence and severity of symptoms in patients with gastric cancer who received chemotherapy,we constructed a symptom network to explore core symptoms and bridge symptoms.Furthermore,the study explores the association between core symptoms and Traditional Chinese Medicine(TCM)constitutions.Methods Patients with gastric cancer who received chemotherapy in the medical oncology and surgical oncology department from March to August 2023 were selected for the study using a convenience sampling method.The MD Anderson Symptom Inventory Gastrointestinal Cancer was used for evaluating gastrointestinal symptoms and their severity among patients receiving chemotherapy for gastric cancer,as well as assessing the classification of TCM constitution among patients.The symptom network model was constructed using the R programming language,and the central index was analyzed to determine the core symptoms and bridge symptoms.Binary logistic regression analysis was employed to assess the association between different physical conditions and the occurrence of core symptoms.Results A total of 346 electronic questionnaires were collected,with 340 valid ones,and the effective recovery rate was 98.3％.The 3 most prevalent and severe symptoms among the 340 patients with gastric cancer were fatigue(85.59％),lack of appetite(82.35％),and taste alteration(81.18％).The centrality index results indicated that grief exhibited the highest intensity,medium,and compactness centrality values(rs=8.23,rb=2.00,rc=0.03),making it the core symptom of this condition.Sleep disorders,lack of appetite,drowsiness,and taste alteration were identified as bridging symptoms with bridge intensities of 0.74,0.76,0.99,and 0.94 respectively.The results of Spearman correlation analysis showed that there was a positive correlation between sadness and qi-deficiency constitution,phlegm-dampness constitution(P＜0.05).The phlegm-dampness constitution was positively correlated with the taste alterations(P＜0.05).Conclusion In patients with gastric cancer,fatigue emerges as the most prominent symptom,while sadness assumes the core symptom.Additionally,sleep disorder,lack of appetite,drowsiness,and taste alteration are bridge symptoms.According to the principles of TCM constitution,qi-deficiency and phlegm-dampness are constitutions associated with a higher risk of experiencing sadness,and phlegm-dampness is a constitution associated with a higher risk of taste changes.Nurses can integrate core symptoms and TCM constitutions characteristics to optimize the strategies for symptom intervention.

Liver cancer is an important public health issue worldwide. With the improvements in high-throughput sequencing and gene editing techniques in recent years, studies have further revealed the biological mechanism of intestinal microflora in the development, progression, and metastasis of liver cancer via the gut-liver axis, and in particular, it has been found that lipopolysaccharide, a component of the outer membrane of gram-negative bacteria, can cause downstream immune cascade reactions. This article reviews the possible mechanism of action of intestinal microflora lipopolysaccharide in the development and progression of liver cancer from the aspects of the association between intestinal environmental changes and liver cancer, immunoregulation by lipopolysaccharide, and preclinical treatment.
