ObjectiveTo analyze the research hotpots and development trends of international nursing ethical decision-making in the past 10 years by bibliometric methods. MethodsLiterature related to nursing ethical decision-making published in the Web of Science core collection database from 2014 to 2023 was retrieved. VOSviewer 1.6.18 software was utilized to visually present and analyze data regarding the number of publications， journal sources， countries of origin， author information， research institutions， key terms， co-cited references， and others. ResultsA total of 149 articles were included， involving 85 source journals， of which Nursing Ethics and BMC Medical Ethics were the most prolific. The number of publications on nursing ethical decision-making showed an overall upward trend， with the United States leading other countries in the number of publications. These publications involved 567 authors from 302 research institutions， and the degree of inter-institutional collaboration was relatively low. Keyword clustering， timeline overlay， and density analysis revealed that current research hotspots and trends included the ethical issues and decision-making in clinical nursing practice， the ethical decision-making level and competence of university nursing undergraduates， the ethical decision-making of nursing managers， and ethical decision-making dilemmas encountered by nursing staff during public health emergencies. ConclusionResearch on nursing ethical decision-making is gradually deepening but remains fragmented， lacking sustainability and collaboration. The ethical decision-making levels and competencies of university nursing students， as well as the field of ethical decision-making among nursing managers， may emerge as novel research hotspots in the future. Henceforth， it is necessary to strengthen in-depth exchanges among authors and institutions， pay close attention to international research frontiers， and enhance both the depth and breadth of research.

OBJECTIVE: To observe the effects of acupuncture on the clinical efficacy, TCM syndromes and quality of life of patients with chronic eczema (CE) of blood deficiency stirring wind. METHODS: Forty-eight patients of CE with blood deficiency stirring wind were randomly divided into an observation group (24 cases, 1 case dropped out) and a control group (24 cases, 2 cases dropped out). Both groups received basic skin care. The observation group received acupuncture at bilateral Shenmai (BL62), Houxi (SI3), Yinlingquan (SP9), Quchi (LI11), Ligou (LR5), Sanyinjiao (SP6), Xuehai (SP10), additional acupoints were supplemented based on symptom differentiation, 20 min each time, 3 times a week for the first 2 weeks, 2 times a week for the subsequent 2 weeks. The control group was treated with mometasone furoate cream, once a day for the first 2 weeks, twice a week for the subsequent 2 weeks. Both groups were treated for 4 weeks. The scores of eczema area and severity index (EASI), itch visual analogue scale (VAS), TCM syndrome, dermatology life quality index (DLQI) of the two groups were observed before and after treatment, the serum level of immunoglobulin E (IgE) was detected, and the clinical efficacy after treatment and follow-up recurrence rate after 4 weeks of treatment completion of the two groups were observed. RESULTS: After treatment, the scores of EASI, itch VAS, DLQI and serum levels of IgE in both groups and the score of TCM syndrome in the observation group were decreased compared with those before treatment (P<0.01)；the above indexes in the observation group were lower than those in the control group (P<0.01, P<0.05). The total effective rate of the observation group was 91.3% (21/23), which was higher than 63.6% (14/22) in the control group (P<0.05). In follow-up, the difference in recurrence rates between the two groups was not statistically significant (P>0.05). CONCLUSION Acupuncture can improve the clinical symptoms, TCM syndrome, quality of life of CE patients with blood deficiency stirring wind.

OBJECTIVE: To analyze the clinical manifestations and genotype of a child with You-Hoover-Fong syndrome (YHFS) to enhance clinical understanding of this disease. METHODS: Clinical data of a child who visited the Department of Pediatric Neurorehabilitation of the Women's and Children's Hospital Affiliated to Xiamen University in March 2025 for global developmental delay was collected. Peripheral blood samples of the child and his parents were collected for chromosomal microarray analysis and whole exome sequencing (WES). Sanger sequencing was performed for parental validation, and candidate variant was assessed for pathogenicity. Clinical and genetic analyses were conducted based on the child's phenotype. A literature review was performed by retrieving previously reported cases of YHFS due to TELO2 gene variants. This study was approved by the Medical Ethics Committee of the Women's and Children's Hospital Affiliated to Xiamen University (Ethics No.: KY-2023-044-K02). RESULTS: The child was a 1-year-and-2-month-old male presenting with global developmental delay, encephalodysplasia, congenital heart disease and distinctive facial features. WES revealed that the child has harbored compound heterozygous variants of the TELO2 gene, namely c.1826G>A (p.Arg609His) and c.1514_1515delAG (p.Glu505Alafs21). Sanger sequencing confirmed that his mother carried a heterozygous c.1826G>A variant and his father carried a heterozygous c.1514_1515delAG variant. Based on the guidelines from the American College of Medical Genetics and Genomics (ACMG), both variants were classified as likely pathogenic (PM2_Supproting+PM3_Strong+PP1+PP3; PVS1+PM2_Supproting). Literature review has identified 9 articles reporting 31 cases of YHFS due to TELO2 gene variants, with primary clinical manifestations including developmental delay, intellectual disability, distinctive facial features, and congenital heart disease. CONCLUSION The c.1826G>A (p.Arg609His) and c.1514_1515delAG (p.Glu505Alafs*21) compound heterozygous variants of the TELO2 gene probably underlay the pathogenesis of this child. Above finding has provided a basis for the clinical and genetic diagnosis of the child, which also enriched the mutational spectrum of the TELO2 gene, and improved understanding of YHFS.

ObjectiveTo investigate the expression level of lysophosphatidyllecithin acyltransferase 4 （LPCAT4） in pancreatic cancer and its effect on the proliferation of pancreatic cancer cells. MethodsIn this study， the differentially expressed genes of patients with KRAS mutant and wild-type pancreatic cancer were analyzed by online database LinkedOmics. The LPCAT4 expression in pancreatic cancer tissues was analyzed online by the University of Alabama at Birmingham Cancer Data Analysis （UALCAN）， Sangerbox and gene expression profile interaction analysis 2 （GEPIA2）. Kaplan-Meier Plotter database was used to explore the correlation between LPCAT4 and the prognosis of patients with pancreatic cancer. The expression of LPCAT4 in human pancreatic cancer cells were detected by quantitative real-time PCR and Western blot analysis. LPCAT4 was knocked down in the high-expressing SW1990 cell line and overexpressed in the low-expressing MIA PaCa-2 cell line. The effects of LPCAT4 expression on cell proliferation were assessed using CCK-8 and EdU assays. STRING and GEPIA2 databases were used to obtain LPCAT4 binding and coexpressed genes in tumors， which were then analyzed by GO and KEGG. ResultsAnalysis of the LinkedOmics online database revealed a significant upregulation of LPCAT4 in patients with KRAS mutant pancreatic cancer compared to patients with KRAS wild-type pancreatic cancer. The online analysis of GEPIA2， UALCAN and Sangerbox 3.0 showed that the expression of LPCAT4 was higher in pancreatic cancer than in normal tissues. Analysis of the Kaplan-Meier Plotter database revealed that high LPCAT4 expression was associated with poorer prognosis in pancreatic cancer patients.Western blot and qPCR results showed that expression of LPCAT4 in pancreatic cancer cell lines was significantly higher than in normal pancreatic ductal epithelial cells. Knockdown of LPCAT4 in SW1990 cells inhibited proliferation， while overexpression in MIA PaCa-2 cells promoted proliferation. Enrichment analysis indicated that LPCAT4 was closely related to sulfur metabolism. ConclusionsLPCAT4 is highly expressed in pancreatic cancer and is associated with poor prognosis of patients. It plays a significant regulatory role in the proliferation of pancreatic cancer cells， with its expression level closely correlated with cell proliferation capacity. These findings reveal the critical role of LPCAT4 in the malignant progression of pancreatic cancer and provide important evidence for its potential as a therapeutic target.

AIM:To examine the impact of the transcription factor 7 analogue 2(TCF7L2)gene polymorphism on the hypoglycaemic effect of ex-enatide in patients with type 2 diabetes mellitus(T2DM).METHODS:A total of 100 newly diagnosed Han Chinese patients with T2DM who had not re-ceived any drug treatment were selected from the Affiliated Hospital of Xuzhou Medical University and treated with exenatide monotherapy for 6 months.The TCF7L2 rs290487 was genotyped by SnaPshot method,and blood glucose levels,lipids profiles and pancreatic function evaluation indica-tors were measured at baseline,3 months and 6 months after exenatide treatment.Multiple linear regression analysis was employed to assess the cor-relation between each indicator and the reduction in glycated hemoglobin(HbA1c)levels after 6 months of exenatide treatment.The expression of TCF7L2 protein in the plasma of T2DM patients was detected by enzyme-linked immunosorbent assay(ELISA)kit.Furthermore,western blotting was con-ducted to ascertain TCF7L2 expression in pancreat-ic tissues obtained from db/db mice and INS-1 cells cultured under high glucose conditions.Lentivirus transfection was used to overexpress or knock down TCF7L2 in insulinoma cell line(INS-1)cells,followed by measurement of KSIS activity and insu-lin content after a 24-hour intervention with exena-tide.RESULTS:The distribution pattern of TCF7L2 rs290487 was found to be in accordance with Har-dy-Weinberg equilibrium(P＞0.05).Following 6 months of exenatide treatment,there was a nota-ble reduction in blood glucose levels and an im-provement in lipid profiles when compared to base-line values.Additionally,there was a significant in-crease in the homeostasis model assessment of be-ta-cell function(HOMA-B)values.Patients with the TT genotype exhibited significantly lower postpran-dial plasma glucose(PPG)levels and HbA1c values compared to those with the CC or CT genotypes(P＜0.05).After adjusting for age,gender,body mass in-dex(BMI),and waist to hip ratio(WHR)in the mul-tiple linear regression model,a significant associa-tion was observed between the rs290487 TT geno-type,baseline HbA1c levels,and family history of diabetes with the reduction in HbA1c after six months of exenatide treatment(P＜0.05).Further-more,individuals with the rs290487 TT genotype demonstrated a notable elevation in TCF7L2 expres-sion in plasma among T2DM patients in comparison to those with the CC genotype(P＜0.05).In particu-lar,pancreatic tissue from db/db mice exhibited markedly elevated TCF7L2 expression compared to db/m mice.However,this up-regulation was re-versed by exenatide treatment.Similarly,INS-1 cells cultured under high glucose conditions dem-onstrated an increase in TCF7L2 expression,which was ameliorated upon exenatide administration.The knockdown of TCF7L2 using shRNA enhanced the KSIS function of pancreatic β cells and aug-mented the insulinotropic effect of exenatide.Con-versely,the upregulation of TCF7L2 impaired the KSIS function of pancreatic β cells and attenuated the insulinotropic effect of exenatide.CONCLU-SION:The TCF7L2 rs290487 gene polymorphism is closely associated with the hypoglycaemic efficacy of exenatide therapy.The risk allele C may diminish the effectiveness of exenatide by impacting the lev-els of PPG and HbA1c in T2DM patients.The muta-tion at TCF7L2 rs290487 site(C→T)influenced the expression of TCF7L2 protein.By exerting its regula-tory effect,exenatide may be capable of regulating the impact of TCF7L2 on the function of pancreaticβ cells.

Objective:To investigate the application of phase angle by bioelectrical impedance in the assessment of malnutrition and its correlation with nutrtition status as measured by several different screening tools in patients on maintenance hemodialysis (MHD).Methods:This was a cross-sectional study, including 151 patients on MHD. Bioelectrical impedance analysis was used to detect body composition in hemodialysis patients. Nutritional Risk Screening 2002 (NRS 2002) scores, body mass index (BMI) and the Global Leadership Initiative on Malnutrition (GLIM) criteria were used to investigate the prevalence of malnutrition in MHD patients. The correlation between phase angle and nutrition-related indicators such as visceral fat area, body weight, skeletal muscle, and serum albumin in MHD patients was analyzed, and the consistency between phase angle and the three screening tools was examined.Results:In a total of 151 patients on MHD, the malnutrition prevalence as measured by BMI, NRS 2002 score and GLIM criteria was 9.27%, 27.81% and 54.97%, respectively. Phase angle in MHD patients was positively correlated with BMI( P<0.01), negatively correlated with impaired nutrition score of NRS 2002( P<0.01), and also associated with nutrition screening results as measured by GLIM criteria( P<0.001). Further study showed that phase angle was positively correlated with body weight, skeletal muscle and serum albumin( P<0.01), but negatively with visceral fat area and extracellular water/total body water( P<0.01). Conclusions:Malnutrition is highly prevalent in MHD patients. Phase angle showed good consistency with BMI, NRS 2002 and GLIM criteria in terms of malnutrition screening, implying the potential application in the assessment of malnutrition in MHD patients. However, the clinical relevance still needs corroboration with future large-scale researches.

Objective    To investigate the perioperative hemodynamic changes of off-pump coronary artery bypass grafting (OPCABG) patients monitored by pulse recorded analysis method (MostCare/PRAM devices) and its relationship with the prognosis. Methods    A total of 89 patients who underwent OPCABG from October 2016 to January 2017 in Beiijng Anzhen Hospital were included, including 53 males and 36 females aged 60.50±8.40 years. The hemodynamic changes were recorded. The patients were divided into two groups (a major adverse cardiovascular events group and a stable group) according to whether major adverse cardiovascular events occurred or not. The difference of hemodynamic changes between the two groups was analysed. Results    The mean percentage increases of stroke volume (SV) in the passive leg raising (PLR) test before opening chest and after chest closure were 23.00%±3.20% and 29.40%±3.70%, respectively. Hemodynamic data were analysed seven times, namely, anaesthesia, opening chest, heparin administration, coronary artery bypass grafting, protamine administration, thoracic closure and after operation. SV was significantly decreased during above periods, while systemic vascular resistance index (SVRI) was significantly increased. Cardiac circle efficiency (CCE) and maximum pressure gradient (dP/dT) were decreased after anaesthesia, and decreased to the lowest value during the procedure of bypass grafting, and then they began to increase gradually after the manipulation of bypass grafting was finished. Stroke volume variation (SVV) and pulse pressure variation (PPV) were slightly decreased during anaesthesia, then increased significantly through the whole surgery. Major adverse cardiovascular events occurred in 9 patients and 4 of them died. The basic mean values of SVRI, SVV and PPV of patients in the major adverse cardiovascular events group before opening chest were significantly higher than those of patients in the stable group. There was no significant difference in the mean values of CCE, dP/dT or SV between the two groups. There was no significant correlation between the prognosis and the mean values of SVRI, SVV, PPV, CCE, dP/dT or SV. Conclusion    The hemodynamic indexes are not stable, thus, it is necessary to monitor the perioperative hemodynamic changes of OPCABG patients timely by MostCare/PRAM device and adjust treatment measures accordingly.
