Palliative care is recognized as an effective measure to improve the quality of life for patients with end-stage diseases， and the significance and role of such patients participating in clinical trials to conquer major diseases has also become a broad consensus. However， due to the special physical， psychological， and social conditions of terminal trial participants， the ethical problems encountered in the trial process are more serious and complex. Drawing on ethical practice experience， these seemingly common phenomena and issues were deeply analyzed. Combined with the palliative care philosophy for end-stage patients， this paper proposed a series of improvement suggestions throughout the entire life cycle of clinical trials， hoping to promote the quality improvement of clinical research in which end-stage patients participate as subjects， while effectively protecting the safety and rights of the subjects and ensuring they receive appropriate palliative care during their participation in clinical trials or clinical-related scientific research.

Objective To analyze the related factors of prognosis in patients with primary Sjogren’s syndrome (SS) complicated with renal damage, and to provide reference for clinical development of personalized prevention and treatment measures. Methods A total of 508 patients with primary SS complicated with renal damage in the First Affiliated Hospital of Xinjiang Medical University from February 2020 to February 2022 were enrolled as study subjects. According to the prognosis status within 3 years, the enrolled patients were divided into good prognosis group (n=426) and poor prognosis group (n=82). Univariate and logistic multivariate regression analyses were adopted to analyze the influencing factors of poor prognosis. Results There were significant differences in hypertension, anemia, renal interstitial chronicity grading, and levels of globulin (GLO), immunoglobulin G (IgG) and hemoglobin between the two groups (P<0.05). Logistic multivariate analysis showed that concurrent hypertension, anemia, increased grade of renal interstitial chronicity, and elevated GLO and IgG levels were risk factors of poor prognosis in patients with primary SS complicated with renal damage, while hemoglobin level was a protective factor (OR: 1.962, 95%CI: 1.056-3.645; OR: 2.467, 95%CI: 1.153-5.278; OR: 17.796, 95%CI: 5.157-61.419; OR: 3.655, 95%CI: 1.812-7.372; OR: 5.732, 95%CI: 2.632-12.480; OR: 0.325, 95%CI: 0.165-0.640, P<0.05). Conclusion Patients with primary SS complicated with renal damage have a higher risk of poor prognosis, which is affected by factors such as hypertension, anemia, and GLO, IgG and hemoglobin levels. Clinically, it is necessary to take active prevention and treatment measures to improve the prognosis of patients.

Transient perivascular inflammation of the carotid artery(TIPIC)syndrome is a relatively rare disease,and ultrasound is the first screening method for initial diagnosis of the disease.Contrast-enhanced ultrasound(CEUS)has unique advantages in the follow-up of patients with TIPIC syndrome.This paper reports a patient with TIPIC syndrome who was treated with acute left neck pain.The inflammation was significantly re-lieved and subsided after treatment with non-steroidal anti-inflammatory drugs.The ultrasound changes of carotid artery lesions in this patient during follow-up were analyzed,and the application value of CEUS in the follow-up diagnosis of this disease was summarized,in the hope of providing clinical reference.

OBJECTIVE: To analyze the carrier rates and profiles of pathogenic and likely pathogenic variants for hearing loss-related genes MYO7A, PCDH15, and CDH23 among neonates in Nanjing city through targeted next-generation sequencing (NGS). METHODS: Heel-prick blood samples were collected from 30 043 newborns delivered at Nanjing Women and Children's Health Care Hospital between March 2022 and April 2024. Dried blood spots were prepared, and genomic DNA was extracted. Targeted NGS was applied to detect variants across the full coding regions of the MYO7A, PCDH15, and CDH23 genes. The carrier rates and profiles of pathogenic and likely pathogenic variants of the three genes were analyzed. This study was approved by the Medical Ethics Committee of Nanjing Maternal and Child Health Care Hospital (Ethics No.: 2021KY-071). RESULTS: The carrier rates of pathogenic and likely pathogenic variants (with ≥ 1 variant site) for the MYO7A, PCDH15, and CDH23 genes were 0.340%, 0.226%, and 0.156%, respectively. A total of 65, 49, and 30 variant types were detected in the MYO7A, PCDH15, and CDH23 genes, respectively. For MYO7A, single base variants were predominant, with the most common variant being c.5581C>T, followed by c.1343+1G>A, c.2837T>G, and c.5660C>T, with allelic frequencies of 0.013% (8/60 086), 0.007% (4/60 086), 0.007% (4/60 086), and 0.007% (4/60 086), respectively. PCDH15 variants were mainly deletions, with the most common variant site being c.4699_4715dupAGAGAAAAGATTCAGAG, followed by c.3441delA, c.440T>G, and c.4733_4736delTCAG, with allelic frequencies of 0.015% (9/60 086), 0.005% (3/60 086), 0.005% (3/60 086), and 0.005% (3/60 086), respectively. For CDH23, single base variants were predominant, with c.6604G>A being the most common, followed by c.6085C>T, c.6050+9G>A, and c.6253+1G>A, with allelic frequencies of 0.013% (8/60 086), 0.012% (7/60 086), 0.005% (3/60 086), and 0.005% (3/60 086). CONCLUSION This study analyzed the carrier rates and profiles of pathogenic and likely pathogenic variants of the MYO7A, PCDH15, and CDH23 genes, which can provide more evidence for the prevention and management of deafness in the region.

Objective:To retrieve, evaluate and summarize the best evidence on the use of bedside ultrasound by ICU nurses to assess the lungs of adult critically ill patients, and to provide a reference for clinical practice and the construction of related processes and protocols.Methods:Based on the "6S" pyramid model, a computer-based search was conducted on relevant computer decision support system, guideline networks, professional associations, and domestic and international databases, the search time limit was from the establishment of the database to June 5, 2024. The panel members who had been trained in the evidence-based course evaluated the included literature with corresponding tools, extracted evidence according to the theme.Results:Twenty-five papers were finally included, including 6 guidelines, 8 expert consensus, 2 expert opinion, 3 clinical decision-making, 3 systematic evaluation, and 3 randomized controlled trials. A total of 35 pieces of evidence were formed from 4 aspects, including personnel training, operation specifications, clinical application (including dyspnea screening, intervention implementation, efficacy evaluation, diaphragm function evaluation) and precautions.Conclusions:The best evidence for lung assessment and intervention in adult critically ill patients based on bedside ultrasound can provide a reference for the adjustment and decision-making of nursing measures for adult critically ill patients. In the subsequent process of evidence transformation, attention should be paid to combining clinical practice and the joint cooperation of medical staff.

Objective To discuss the different types of benefits of family care for Alzheimer's disease(AD)and its influencing factors based on the latent profile analysis.Methods A total of 154 family caregivers of patients with AD who were treated in Shaoxing Seventh People's Hospital,from July 2020 to September 2023 were selected as the research objects.A cross-sectional survey was conducted on the family caregivers of patients with AD by using general information questionnaire and disease benefit scale,and the results were profile analyzed.The influencing factors of family caregivers of patients with AD were analyzed by multiple linear regression.Results Family caregivers of AD can be roughly divided into three potential profile categories:high support positive type,stable health type and low growth introversion type.Multiple linear regression analysis showed that age,family income per capita,anxiety and social support were the independent influencing factors of family caregivers of AD(P＜0.05).Conclusion There are characteristic differences in the types of disease benefit of family caregivers of AD.Nurses can take personalized psychological counseling and intervention measures according to different types of disease benefit of family caregivers to maintain the mental health of family caregivers of AD.
