Purpose This study aimed to investigate the expression and clinical significance of TLDC2 in colorec-tal adenocarcinoma.Methods Data from the human protein atlas(HPA)and the cancer genome atlas(TCGA)indi-cated that TLDC2 was highly expressed in colorectal adenocarcinoma.We further analyzed the expression of TLDC2 in 400 colorectal adenocarcinomas and 447 other solid tumors using tissue microarrays and immunohistochemical(IHC)staining.Result The positive expression rate of TLDC2 was significantly higher than that of SATB2 in colorectal ade-nocarcinomas(96.5％vs 87.0％,P＜0.000 1).TLDC2 positivity exceeded that of SATB2 in both low-or high-grade colorectal adenocarcinoma(99.4％vs 88.7％,P＜0.000 1;83.3％vs 79.2％,P=0.669 9).In addition,the expression of TLDC2 and SATB2 was evaluated in 447 cases of other types of solid tumors.TLDC2 was expressed in neuroendocrine tumors as well as in gastric and appendiceal adenocarcinomas,whereas SATB2 was detected in a small number of melanomas,ovarian cancers,breast cancers and gallbladder cancers.The positive and specificity of TLDC2 for colorectal adenocarcinoma were 97％(95％CI=0.94-0.98)and 85％(95％CI=0.81-0.88),respectively.Combined detection of TLDC2 and SATB2 yielded a sensitivity of 96％(95％CI=0.93-0.97)and a specificity of 93％(95％CI=0.90-0.95).Conclusion Analysis of large-scale datasets and IHC staining demonstrated that TLDC2 is a highly sensitive and specific biomarker for colorectal adenocarcinoma.

Objective:To understand the potential characteristics of decision-making preparation in outpatient hypertensive patients based on latent profile analysis, to identify the influencing factors of different categories of decision-making preparation levels, and to explore the performance of different decision-making preparation types in facilitation of patients involvement in treatment decision-making.Methods:Through a cross-sectional study, 350 hypertensive patients attending outpatient clinics in five different types of healthcare institutions (general hospitals, specialised hospitals and community hospitals) in Tianjin during January to May 2024 who met the inclusion and exclusion criteria were selected by the convenience sampling method as study subjects. General Information Questionnaires, Preparation for Decision Making Scale, and Facilitation of Patient Involvement Scale were used for investigation.Results:Totally 350 valid questionnaires [178 males and 172 females aged 25-89(57.24 ± 13.39)years old] were collected. The decision-making preparation score of outpatient hypertensive patients was (64.19 ± 18.69). The latent profile analysis results showed that the decision-making preparation of outpatient hypertensive patients could be divided into three potential categories: decision-making information scarcity type accounted for 20.0%(70/350), decision-making balance negotiation type accounted for 39.7%(139/350), and decision-making preparation adequacy type accounted for 40.3%(141/350). The results of multiple Logistic regression analysis showed that age, medical insurance type, occupation, and children′s condition were the influencing factors for the potential categories of decision-making preparation in outpatient hypertensive patients (all P<0.05). Age [less than 35 years old: OR(95% CI)=0.127(0.020-0.796)], occupation [on the job: OR(95% CI)=2.010 (1.034-3.906)], were the influencing factors of decision-making balance negotiation group (all P<0.05). Medical insurance type [basic medical insurance for urban employees: OR(95% CI)=0.372(0.193-0.720)], occupation [on the job: OR(95% CI)=2.500(1.270-4.920)], children′s condition[junior and senior high school: OR(95% CI)=0.391(0.190-0.802)] were the influencing factors of decision-making preparation adequacy group (all P<0.05). Conclusions:The level of promoting patient participation among outpatients with hypertension is relatively high, and there are differences in the perceived degree of promoting patient participation among patients with different types of decision preparation.It is recommended that medical staff provide decision-making related information based on the characteristics of different decision-making preparation categories of patients, encourage patients to actively participate in decision-making, and construct targeted decision support plans.

Objective To analyze the situation of life sciences and medical research involving human subjects conducted in a public hospital in Ningxia from 2020 to 2022 and explore the problems in the current management of such research and pro-vides suggestions for improvement.Methods Data were collected from research project application documents,task assign-ments,progress reports,final reports,and statistical tables of clinical drug trials conducted in the hospital from 2021 to 2022.Statistical analysis was performed on the life sciences and medical research involving human subjects.Results The number of research projects involving human subjects in the hospital increased annually from 2020 to 2022,accounting for more than 50%of the total projects.Over the three years,the sample size exceeded 100,000,and the number of projects with a cumulative collec-tion of more than 3,000 individuals showed an upward trend.However,the project registration rate was less than 10%.These types of research involve a large number of biological samples and information data,which have research value.However,re-searchers lack awareness of project registration,highlighting the need for greater attention from the hospital.Conclusion It is a trend to explore the medical value of this type of research in depth.The hospital should closely follow relevant national and re-gional policies,conduct dynamic monitoring and evaluation,and enhance supervision and management capabilities as a key factor in protecting biological samples and information data.This study also provides reference for other public hospitals in carrying out related regulatory work.

Objective:To understand the current state of ethical competence levels of nurses and analyse the factors that influence them, in order to inform the development of targeted training programmes.Methods:This study adopted a cross-sectional survey method and used convenience sampling to select 825 clinical nurses from Tianjin Chest Hospital as the survey objects from July to August, 2023, and a questionnaire survey was conducted using the General Information Questionnaire, the Ethical Competence Scale, Ethical Competence Support Scale, and Ethical Safety Scale.Results:A total of 818 valid questionnaires were retracted. Among the 818 nurses, 48 were males and 770 were females, the age was (33.19 ± 7.40) years. The total score of nurses ′ Ethical Competence, Ethical Competence Support and Ethical Safety were (118.08 ± 19.96), (215.07 ± 32.02), (48.93 ± 7.55) points, all of which were at a high level. The total score of nurses ′ ethical competence were positively correlated with ethical competence support and ethical safety ( r=0.856, 0.830, both P<0.01); multivariate linear regression analysis showed that the department, the level of ethical competence support, and the level of ethical safety were the influencing factors of the level of ethical competence ( t=5.19, 12.35, 3.88, all P<0.01). Conclusions:Nurses ′ ethical competence, ethical competence support, and ethical safety were at a high level, and the department, the level of ethical competence support, and the level of ethical safety were the factors influencing the level of ethical competence. Nursing managers can provide more ethical education and address ethical issues in multiprofessional discussions, strengthen organizational and personal support for nurses ′ ethical competence, improve nurses ′ ethical safety, and help them implement good ethical care.

Objective:To investigate the current situation of the use of transjugular intrahepatic portosystemic shunt (TIPS) for portal hypertension, which should aid the development of TIPS in China.Methods:The China Portal Hypertension Alliance (CHESS) initiated this study that comprehensively investigated the basic situation of TIPS for portal hypertension in China through network research. The survey included the following: the number of surgical cases, main indications, the development of Early-TIPS, TIPS for portal vein cavernous transformation, collateral circulation embolization, intraoperative portal pressure gradient measurement, commonly used stent types, conventional anticoagulation and time, postoperative follow-up, obstacles, and the application of domestic instruments.Results:According to the survey, a total of 13 527 TIPS operations were carried out in 545 hospitals participating in the survey in 2021, and 94.1% of the hospital had the habit of routine follow-up after TIPS. Most hospitals believed that the main indications of TIPS were the control of acute bleeding (42.6%) and the prevention of rebleeding (40.7%). 48.1% of the teams carried out early or priority TIPS, 53.0% of the teams carried out TIPS for the cavernous transformation of the portal vein, and 81.0% chose routine embolization of collateral circulation during operation. Most of them used coils and biological glue as embolic materials, and 78.5% of the team routinely performed intraoperative portal pressure gradient measurements. In selecting TIPS stents, 57.1% of the hospitals woulel choose Viator-specific stents, 57.2% woulel choose conventional anticoagulation after TIPS, and the duration of anticoagulation was between 3-6 months (55.4%). The limitation of TIPS surgery was mainly due to cost (72.3%) and insufficient understanding of doctors in related departments (77.4%). Most teams accepted the domestic instruments used in TIPS (92.7%).Conclusions:This survey shows that TIPS treatment is an essential part of treating portal hypertension in China. The total number of TIPS cases is far from that of patients with portal hypertension. In the future, it is still necessary to popularize TIPS technology and further standardize surgical indications, routine operations, and instrument application.

Malnutrition is defined as insufficient or excessive nutrient intake, an imbalance of essential nutrients, or impaired utilization of nutrients. These issues can result in changes in body composition, decreased physiological function, and impaired mental status, all of which negatively affect patients' quality of life, physical function, ability to engage in independent activities, and overall clinical outcomes. Consequently, malnutrition can lead to higher morbidity rates, prolonged hospital stays, increased mortality rates, and elevated healthcare expenditures. Regardless of patients' age, medical history, or physical condition, all individuals should be screened for malnutrition risk using a malnutrition risk screening tool. This approach facilitates the early identification of patients at risk of malnutrition, allowing for the timely initiation of personalized nutrition support to prevent or reverse malnutrition. In clinical practice, various malnutrition risk screening and assessment tools are available, tailored to different diseases, age groups, and medical environments. However, these tools vary in their effectiveness, consistency, reliability, and applicability. This paper provides an overview of the research progress on methods for screening malnutrition and assessing malnutrition risk in hospitalized adult patients.
