Objective:To explore the factors influencing ethical sensitivity of oncology nurses.Methods:Using purposive sampling, 15 oncology nurses from 13 tertiary general hospitals in Foshan, Guangdong Province were selected as research participants from July to September 2023. In-depth semi-structured interviews were conducted, and Colaizzi's seven-step content analysis method was applied to organize and analyze the collected data.Results:A total of 4 themes were summarized: insufficient clinical experience and knowledge reserve; lack of ethical education and management system processes; high-pressure working environment and communication barriers; and the constraints of the cultural concept of "valuing life over death".Conclusions:Oncology nurses have insufficient ethical sensitivity. Nursing managers should establish a systematic ethical education system, improve ethical management systems, optimize the clinical working environment, and integrate cultural sensitivity education to jointly enhance nurses' communication skills. Attention should also be paid to the inheritance of clinical experience from senior nurses, so as to improve the ethical sensitivity of oncology nurses in a multidimensional way.

Objective To investigate the impacts of epidural anesthesia with ropivacaine combined with dezocine on lower limb motor nerve block and maternal and infant outcomes in primipara undergoing painless delivery.Methods A total of 159 primiparas who delivered in Nanjing Jiangbei Hospital were selected as the research objects,and divided into the blank group(53 cases),the ropivacaine group(53 cases)and the combined group(53 cases)by the random number table method.Parturients in the blank group were given natural delivery mode,parturients in the ropivacaine group were given ropivacaine epidural anesthesia,and parturients in the combined group were given dezocine anesthesia on the basis of ropivacaine.Analgesic effect at different time points,time of the first,second and third stage of labor,pressing times of analgesic pump,lower limbs motor nerve block,maternal and infant outcomes,and adverse reactions of parturients were compared among the three groups.Results At 10 minutes after analgesia,60 minutes after analgesia,when the cervix was fully dilated and when the fetus was delivered,the VAS scores of the parturients in the ropivacaine group and the combined group were lower than those in the blank group(P<0.05),and the VAS scores of the parturients in the combined group were significantly lower than those in the ropivacaine group(P<0.05).There was no significant difference in the time of the first,second or third stage of labor of parturients among the three groups(P>0.05);The pressing times of analgesic pump of parturients in the combined group was significantly less than that in the ropivacaine group(P<0.05).There was no statistically significant difference in terms of low limb motor nerve block after painless labor of parturients among the three groups(P>0.05).There were no statistically significant differences in the perineal incision rate or the Apgar scores of newborns at 1 minute and 5 minutes after birth among the three groups(P>0.05).The usage rate of forceps and the rate of conversion to cesarean section in the combined group were significantly lower than those in the ropivacaine group and the blank group(P<0.05).There was no statistically significant difference in the incidence of total adverse reactions among the blank group,the ropivacaine group and the combined group(P>0.05).Conclusion The combination of ropivacaine and dezocine for epidural anesthesia has a better analgesic effect on primiparas with painless delivery,has a smaller impact on lower limb motor nerve block in parturients,and can achieve better maternal and infant outcomes.

Objective:To observe the effect of five element music therapy combined with progressive muscle relaxation(PMR)training on psychological stress and sleep quality in non-small cell lung cancer(NSCLC)chemotherapy patients.Methods:This was a prospective randomized controlled study,95 NSCLC chemotherapy patients were divided into control group(47 cases)and study group(48 cases)by random number table method.Both groups of patients received chemotherapy,the control group received PMR on this basis,while the study group received five element music therapy combined with PMR training.Self-rating depression scale(SDS),self-rating anxiety scale(SAS),sleep duration,Pittsburgh sleep quality Index(PSQI),Piper fatigue revised scale(PFS-R),European cancer research and treatment organization quality of life inventory(EORTC QLQ-C30),and Karnofsky Functional Status(KPS)scores were compared between the two groups.Results:Compared with the control group at 4 weeks after intervention,the study group had lower SAS,SDS,and PSQI scores,longer sleep duration,lower emotional,behavioral,cognitive,and sensory scores,and higher EORTC QLQ-C30 and KPS scores(P＜0.05).Conclusion:Five element music therapy combined with PMR training in non-small cell lung cancer(NSCLC)chemotherapy patients,can effectively improve the psychological stress,sleep quality,and healthy behavior,alleviate cancer-related fatigue,and enhance their quality of life.

Objectives: Hypoparathyroidism (HP) is a rare endocrine disorder caused by parathyroid hormone (PTH) defi ciency. The PTH is a candidate gene for familial isolated hypoparathyroidism (FIH). This study aimed to investigate the pathogenicity of two novel rare variants (RVs) ofPTH through in vitro functional study. Methods: Targeted next-generation sequencing was used to identify candidate gene mutations. Clinical data were retrospectively collected. Wild-type (WT) PTH was used as a template for site-directed mutagenesis to create mutant eukaryotic expression plasmids, which were transfected into cells. Treated with or without 4-phenylbu tyric acid (4-PBA), the levels of intact PTH (iPTH) and PTH (1-84) were measured by chemiluminescence, and protein expression was assessed using Western blotting. Results: Two patients carrying PTH mutations (c.154G > A: p.Val52Ile, c.270G > T: p.Leu90Phe) were identified.Patient 1, a 45-year-old male, presented with carpal and pedal numbness, muscle cramps, and low serum calcium (1.29 mmol/L). Patient 2, a 12-year-old female, had muscle twitches, convulsions, low calcium (1.50 mmol/L), and iPTH of 4 pg/mL. The iPTH or PTH (1-84) levels in the medium transfected with mutant Val52Ile and Leu90Phe PTH decreased by 31%–38%, and 51%–96% compared to WT (allP < 0.05), which were not rescued by 4-PBA. No significant changes in intracellular PTH expression were observed. Conclusions In this study, two novel RVs of PTH(Val52Ile and Leu90Phe) were identified that may impair hormone synthesis and secretion. Our study has broadened the mutation spectrum of the PTH and shed light on potential mechanisms underlying FIH.
