Background and Aims:Portal hypertensive colopathy(PHC)is a common complication of portal hypertension in patients with liver cirrhosis.It may lead to gastrointestinal bleeding,yet its underlying pathogenesis remains unclear,and systematic research in China is limited.This study aimed to analyze the colonoscopic features in cirrhotic patients and to explore their associations with relevant clinical factors.Methods:A retrospective analysis was conducted on 99 cirrhotic patients who underwent colonoscopy at Xingtai People's Hospital between July 2020 and December 2024.Colonoscopy,gastroscopy,and clinical data were reviewed.Differences between patients with PHC and those without were compared in terms of sex,Child-Pugh classification,platelet count,presence of ascites,and hepatic encephalopathy.Multivariate logistic regression was used to identify independent risk factors for PHC.Additionally,colorectal lesion detection rates were compared with those of a contemporaneous cohort of 444 participants undergoing national colorectal cancer(CRC)screening at the same center.Results:Among the 105 patients with cirrhosis,the detection rates of PHC,adenomatous polyps,and CRC were 32.32%,28.28%,and 3.03%,respectively,while only 37.37%had no abnormal findings.No serious colonoscopy-related complications were observed.The proportion of males in the PHC group was significantly higher than in the non-PHC group(78.13%vs.50.75%,P=0.009).The PHC group also showed significantly higher rates of Child-Pugh class B/C,and lower platelet count(all P<0.05).There was no statistically significant difference in the incidence of ascites and hepatic encephalopathy between the two groups(P>0.05).Multivariate analysis identified that male gender(OR=3.307,95%CI=1.219-8.971)and Child-Pugh class B/C(OR=2.867,95%CI=1.046-7.861)were independent risk factors for PHC.Compared to the CRC screening cohort,cirrhotic patients had a similar adenoma detection rate(28.28%vs.25.00%,P=0.499),and a slightly higher colorectal cancer detection rate that did not reach statistical significance(3.03%vs.0.68%,P=0.135).Conclusion:Colonoscopy revealed a high rate of abnormalities in cirrhotic patients,with PHC and adenomatous polyps being the most common findings.Routine colonoscopy is recommended for cirrhotic patients without contraindications,especially males,and patients with Child-Pugh class B/C,to facilitate early detection of PHC and precancerous lesions,thereby reducing the risk of lower gastrointestinal bleeding and missed diagnoses of malignancy.

Objective:To develop the Economic Toxicity Scale for Kidney Transplantation Patients, and to test the reliability and validity of the scale.Methods:Drawing upon Coleman′s social capital theory and the six subfields associated with economic toxicity put forward by European scholars, the initial version of the scale was developed via expert correspondence consultation and a preliminary survey. This was accomplished by building upon existing literature and conducting semi-structured interviews. A total of 261 cases of kidney transplantation patients from March to October 2022 admitted to the First Affiliated Hospital of Shandong First Medical University were investigated for reliability and validity test.Results:The Economic Toxicity Scale for Kidney Transplantation Patients included 6 dimensions, 31 entries. The total scale had a Cronbach alpha coefficient of 0.910 and the subscale had Cronbach alpha coefficient ranging from 0.798 to 0.943. The retest reliability coefficient for the total scale was 0.948, while the six dimensions ranged from 0.732 to 0.942.Conclusions:The scale demonstrates strong reliability and validity, making it a reliable tool for objectively evaluating the economic toxicity of kidney transplantation patients.

Diacylglycerol (DAG) is an intermediate product in lipid metabolism and plays an important physiological role in human body. It is mainly prepared by hydrolyzing lipid with lipase. However, research on the detection method of 1, 2-diacylglycerol (1, 2-DAG) and 1, 3-diacylglycerol (1, 3-DAG) and catalytic specificity of lipase was not enough, which limits its wide application. To address these challenges, an efficient quantitative detection method was first established for 1, 2-DAG (0.025-0.200 g/L) and 1, 3-DAG (0.025-0.150 g/L) by combining supercritical fluid chromatography with evaporative light scattering detector and optimizing the detection and analysis parameters. Based on the molecular docking between Thermomyces lanuginosus lipase (TLL) and triolein, five potential substrate binding sites were selected for site-specific saturation mutation to construct a mutation library for enzyme activity and position specificity screening. The specificity of sn-1, 3 of the I202V mutant was the highest in the library, which was 11.7% higher than the specificity of the wild type TLL. In summary, the position specificity of TLL was modified based on a semi-rational design, and an efficient separation and detection method of DAG isomers was also established, which provided a reference for the study of the catalytic specificity of lipase.

Objective:To explore the effects of online supportive disclosure therapy on the self-expression level, professional identity, dimission intention, and turnover rate of pre-dimission nurses, in order to provide a reference for nursing managers to stabilize the nursing team.Methods:A quasi experimental research method was used, and a convenient sampling method was used to select 192 pre resigned nurses from Shandong Provincial Third Hospital, the First Affiliated Hospital of Shandong First Medical University, and Shandong First Medical University Affiliated Provincial Hospital from October 2021 to December 2022 as the research subjects. They were divided into a control group and an experimental group by random number table method, with 96 nurses in each group. The control group received routine exit interviews, while the experimental group received online supportive disclosure therapy intervention based on this. The self-expression level, professional identity, dimission intention, and turnover rate of two groups of nurses before and 1, 2 months after the intervention were evaluated.Results:Finally, 94 nurses in the control group and 92 nurses in the experimental group completed the study. There were no significant differences in the self-expression level, professional identity, dimission intention before the intervention between the two groups ( P>0.05). After 1 and 2 months of the intervention, the scores of the Pain Self Disclosure Index, Nurse Professional Identity Rating Scale, and Resignation Intention Scale of the experimental group were 36.33 ± 5.13, 73.88 ± 8.72, 14.18 ± 1.12 and 34.22 ± 6.78, 98.26 ± 11.29, 6.16 ± 1.19, respectively,and the control group were 28.06 ± 8.23, 64.72 ± 10.39, 17.82 ± 1.37 and 44.26 ± 7.62, 79.82 ± 8.66, 9.18 ± 1.06, there were statistically significant differences between the two groups ( t values were -13.54 to -2.11, all P<0.05); there were statistically significant differences in the inter group effects, time effects, and interaction effects of the scores on the Pain Self Disclosure Index, Professional Identity Rating Scale, and Resignation Intention Scale between the two groups ( F values were 5.12 to 14.82, all P<0.05). The turnover rate of nurses in the experimental group was 1.09% (1/92), lower than 8.51% (8/94) in the control group, and the difference between the two groups was statistically significant ( χ2=1.59, P<0.05). Conclusions:Online supportive disclosure therapy can improve the self-expression level and professional identity of pre-dimission nurses, and reduce their willingness to resign and turnover rate.

Objective:To systematically evaluate the impact of the three major nuclear accidents at Three Mile Island, Chernobyl and Fukushima on the mental health status of emergency responders.Methods:MeSH and Entry Terms were searched. Relevant literature on the mental health consequences of the emergency responders to the Three Mile Island, Chernobyl, and Fukushima nuclear accidents were retrieved from PubMed, Web of Science, and APA PsycINFO databases, and screened and reviewed.Results:Totally 37 studies were included. General psychological distress, depression, anxiety, post-traumatic stress disorder and other abnormal psychological problems are prevalent among emergency responders following nuclear accidents. The psychological impact of the Chernobyl nuclear accident was most profound, causing serious mental disorders such as organic mental disorder and personality disorder among the clean-up workers. The mental health condition of emergency responders was associated with disaster-related emergency response tasks and the social factors brought in nuclear accidents.Conclusions:General psychological distress, anxiety, depression, post-traumatic stress reaction/disorder, severe mental disorder and other long-term abnormal psychological problems are common among first responders after nuclear accidents, and baseline mental health and psychological interventions require further study.
