Background Depressive symptoms have become a significant factor affecting the physical and mental health of the occupational population, and workers in petroleum refining enterprises face multiple stressors in their work environment. Objective To explore the impact of occupational noise exposure on depressive symptoms among workers in a petroleum refining enterprise. Methods This cross-sectional study was conducted in July 2024 using a questionnaire survey among workers of a petroleum refining enterprise in Hainan Province. Basic information of the subjects was collected. The Center for Epidemiologic Studies Depression Scale (CES-D) was used to measure depressive symptoms, the Chinese version of the Pittsburgh Sleep Quality Index (PSQI) scale was used to assess sleep quality, and the Chinese version of the Effort-Reward Imbalance (ERI) scale was used to evaluate occupational stress. Chi-square test was employed to compare the differences in reporting depressive symptoms among populations with different characteristics. Binary logistic regression models were used to analyze the impact of occupational noise exposure and other factors on depressive symptoms. Results The overall positive rate of depressive symptoms in the study population was 42.7%. The results of the multifactor analysis indicated that compared with the control group, employees in both the low-exposure and high-exposure groups had elevated odds of depressive symptoms, with OR (95%CI) of 2.244 (1.131, 4.454) and 1.970 (1.009, 3.850), respectively. This association remained robust after adjusting for potential confounders, including gender, age, work tenure, and other occupational exposures. Additionally, female [OR (95%CI)=1.483 (1.039, 2.118)], exposure to benzene, toluene, or xylene [OR (95%CI)=1.621 (1.208, 2.174)], sleep disturbance [OR (95%CI)=3.772 (2.942, 4.838)], and occupational stress [OR (95%CI)=2.018 (1.575, 2.585)] were also significantly associated with higher odds of depressive symptoms. Conclusion The positive rate of depressive symptoms is relatively high among employees in this petrochemical enterprise, and occupational noise exposure may be a risk factor for depressive symptoms.

Objective The purpose of the study is to breed homozygous interferon-γ knockout(IFN-γ-/-)mice and optimize the breeding strategies to achieve continuous and stable reproduction of IFN-γ-/-mice,which could be used as an ideal animal model for fundamental research.Methods Initially,heterozygous IFN-γ knockout(IFN-γ+/-)C57BL/6J mice were used as the parental generation for breeding.Subsequently,3 breeding strategies were employed using the offspring:(1)female heterozygotes mated with male heterozygotes;(2)male homozygotes mated with female heterozygotes;(3)female homozygotes mated with male homozygotes.The number and survival rate of IFN-γ-/-mice were compared across the three breeding strategies to determine the optimal breeding strategy.Under the optimal strategy,the effects of female mating age and diet type on the reproductive performance of IFN-γ-/-mice were further evaluated.Data from the first three litters of 60 IFN-γ-/-female mice,including litter size,number of weaning survivors,and weaning survival rate,were recorded and analyzed.In addition,the effects of dietary supplementation of pregnant mice and environmental optimization measures,such as the provision of shelters,were evaluated.Results Under conditions where the nutritional needs of pregnant mice were adequately met by supplementation with egg yolk and sunflower seeds,mating of female and male IFN-γ-/-mice result ed in a litter size of five to eight IFN-γ-/-mice,demonstrating higher efficiency compared to other breeding strategies.In addition,diet type and mating age significantly influenced female reproductive performance.When 7～9 weeks old female IFN-γ-/-mice were mated to male IFN-γ-/-mice and fed a high-protein breeding diet,litter size(6.9±1.7),weaning survival number(6.5％±2.0％)and weaning survival rate(93.2％±17.8％)were higher than those under other conditions.In addition,providing shelters to prevent fighting between breeding pairs further improved reproductive outcomes.Conclusions By adopting an optimized breeding strategy,combined with a high-protein diet,nutritional supplementation,and standardized mating age management,the breeding efficiency and stability of IFN-γ-/-mice can be significantly improved.This provides a reliable animal model for related research.

Objective:Reviewed the scope of the application of time-driven activity based costing(TDABC) in nursing costing, and the connotation of time-driven job costing, the current status of research, and the evaluation of the application effect were systematically sorted out. In order to provide an effective method for the improvement of nursing cost accounting level in China.Methods:In accordance with the scope review methodology of Arksey and O′Malley, the Cochrane Library, PubMed, Web of Science, Embase, Scopus, CINAHL, SinoMed, CNKI, Wanfang and VIP Database were systematically searched for relevant literature on the application of nursing costingrelated literature on time-driven job costing. The time frame was from the construction of the database to March 1, 2024. Summarization and analysis were conducted independently by 2 trained and qualified researchers, and third-party experts were invited to share decision-making in case of disagreement.Results:Twenty-seven literatures from nine countries were included. A review of the literature revealed that time-driven job costing is used throughout the entire process of nursing costing, and the results of its application include optimizing the allocation of nursing resources, accurately accounting for the true costs of clinical care pathways and processes, and assisting in the analysis of nursing cost decisions.Conclusions:TDABC has been widely recognized internationally, effectively supporting refined cost management and promoting decision-making optimisation. However, the current development of TDABC in nursing costing in China is yet to be perfected. In the future, we should deeply explore the combination of TDABC with the local healthcare system, and promote its wide application in China, so as to achieve the dual optimisation of cost control and nursing quality, and to better reflect the economic and social value of nursing services.

Objective:To understand the current status of financial toxicity in patients with heart failure and the factors affecting it, and to provide ideas for making personalized and informed decisions.Methods:Using a scoping review methodological framework, PubMed, Embase, Cochrane Library, Web of Science, China National Knowledge Infrastructure, VIP, Wanfang, and SinoMed Databases were searched and screened for relevant literature on financial toxicity in patients with heart failure, with a timeframe of January 1, 2014-October 31, 2023, respectively. Relevant literature was identified based on inclusion and exclusion criteria, and data were extracted, collected, summarized, and the findings were reported.Results:Ten literatures that met the inclusion and exclusion criteria were identified. The results showed 5 cross-sectional surveys, 2 qualitative studies, and 1 each of reviews, mixed studies and commentaries. Heart failure patients generally faced high levels of financial toxicity, the incidence and severity of patient financial toxicity varied somewhat between study outcomes. Factors influencing financial toxicity in heart failure patients included age, education level, family income level, discussion of medical costs with physicians, type of insurance the patient had, and occupational status.Conclusions:In the future, we can develop and apply a specialized assessment tool for financial toxicity in heart failure patients in China, further explore the factors affecting financial toxicity in heart failure patients, and formulate personalized treatment plans and financial support strategies for patients according to the influencing factors, so as to reduce the impact of financial toxicity on heart failure patients.

Childhood arterial ischemic stroke (AIS) refers to an ischemic stroke caused by intracranial artery stenosis or occlusion that occurs between the ages of 29 days and 18 years. Although relatively rare, AIS is an important cause of disability or death in children. The etiologies and risk factors for AIS in childhood are significantly different from those in adults. This article reviews the common causes and risk factors for AIS in childhood.

Objective:To investigate the safety of selective feticide by radiofrequency ablation (RFA) in dichorionic triamniotic (DCTA) triplets and factors related to the clinical outcome.Methods:A retrospective cohort study was designed to review the clinical records and pregnancy outcome of DCTA triplets patients who underwent RFA for selective feticide performed at the First Affiliated Hospital of Southern University of Science and Technology, Shenzhen People's Hospital from January 1,2016 to January 1,2020. Placentas were collected after delivery for gross examination and perfusion study with the mixture of vinylidene chloride and self-curing denture acrylic.Results:A total of 12 DCTA cases were recruited. Selective feticide by RFA were performed at a mean gestational age of 15.6 weeks, and cases delivered at a mean gestational age of 36.9 weeks (34 +4-38 +2 weeks). Eight of the cases undertook invasive prenatal diagnosis weeks after RFA. The interval between RFA to delivery and gestational ages at delivery were similar between women undertook prenatal diagnosis and those who did not ( P>0.05). Six of the 23 newborns (26%) were small for gestational age. The average birth weight of either monochorionic singleton fetus or the remained co-twin of the monochorionic diamniotic (MCDA) twin as lower than that of singleton pregnancy ( P<0.001). One case of DCTA (8.3%) underwent intrauterine fetal death of the MCDA co-twin 4 h after RFA. Fetal tachycardia and cessation of fetal movement of the co-twin were observed before death. By the time of delivery, placental examination revealed the pale anemia look of the placental part of the co-twin and the reddish appearance of the part of the reduced fetus, which suggested a hypovolemic shock after an uncompleted RFA as the cause of co-twin death. A total of 10 MCDA placentas from cases with a living MCDA co-twins were collected. Various degree of placental perfusion on the reduced fetal side of placenta was noticed in nine cases. The co-twin with the placenta which did not have such kind of perfusion had a birth weight at the lowest percentile. Conclusion:Selective feticide by RFA is a safe procedure for DCTA triplet, and prenatal diagnosis has no adverse impact on pregnancy outcome. Ultrasound monitoring of fetal heart rate and fetal movement of the MCDA co-twin after RFA is helpful for predicting clinical outcome. Postnatal placental examination provides clues for adverse outcome, and the growth potential of the MCDA co-twin might be related to the type of anastomosis between the two fetuses.

Objective:To investigate the effect and necessity of fine operation on the improvement of the preparation outcome of paclitaxel (albumin-binding) intravenous infusion for injection.Methods:The detailed refinement of the preparation method in the specification of paclitaxel (albumin-binding) for injection was developed. The fine operation of paclitaxel (albumin-binding) for injection mainly consists of two parts: The mixing method of solvent and drug: including syringe needle length into drug vial, solvent injection speed, state of drug waiting for dissolution, and the shaking speed of the drug vial. The method of extracting the dissolved liquid in the drug vial and injecting it into a 100 ml sterile empty 0.9% sodium chloride injection bottle: including the speed of refilling the 100 ml sterile empty 0.9% sodium chloride injection bottle, and restoring the pressure balance inside and outside the infusion bottle. The effect of fine operation on the preparation of paclitaxel (albumin-binding) for injection was evaluated by comparing the production of foam and the preparation time before and after the implementation of fine operation.Results:Before and after the implementation of fine operation, the foaming rate of the foam in the drug vial decreased from 28.57% (10/35) to 12.50% (12/96), the difference was statistically significant ( χ2 value was 4.471, P=0.029); and the foaming rate of the mixed liquid from the drug vial into the 100 ml sterile empty 0.9% sodium chloride injection bottle decreased from 46.15% (6/13) to 9.09% (3/33), the difference was statistically significant ( χ2 value was 8.140, P value was 0.004); and the preparation time of single drug was reduced by 3.37 minutes after the implementation of fine operation, the difference was statistically significant ( t value was 79.744, P<0.05). Conclusion:The preparation method of fine operation of paclitaxel (albumin-binding) for injection is operable, safe and reliable. After implementation, it can effectively reduce the production of foam in the drug vial and infusion bottle, improve the stability of drug preparation, shorten the preparation time, and ensure the safe, timely and effective medication for patients.
