Objective:To explore the effectiveness of interprofessional cooperative simulation in teaching emergency care for shock patients among intensive care unit (ICU) undergraduate nursing students.Methods:An interprofessional cooperative simulation-based teaching faculty team was established for ICU undergraduate nursing students, and a shock case library was developed. Using convenience sampling, 32 ICU undergraduate nursing students in 2022 were selected as the control group and received conventional simulation-based teaching, with students rotating through roles as nurses, standardized patients, doctors, and family members. In the experimental group, 34 ICU undergraduate nursing students in 2023 and 24 ICU clinical medicine interns were recruited to act as doctors for interprofessional cooperative simulation-based teaching. Each group was divided into subgroups, with each subgroup consisting of 4-5 nursing students. One group completed simulation-based training per month for a total of 8 sessions, with each session lasting 3 hours. The teaching adopted the on-site "tidal ward" in situ simulation, and the scenarios included patient history collection and health assessment, shock emergency care, nursing evaluation, and health education. The differences between the two groups of nursing students were compared in terms of ICU exit theoretical assessment score, objective structured clinical examination skill assessment score, and satisfaction with simulation-based teaching. SPSS 22.0 was used for independent samples t test and Mann-Whitney U test. Results:The experimental group achieved significantly higher scores in theoretical assessment (84.65±8.06), total score of satisfaction with simulation-based teaching (101.00±5.13), and clinical learning and multiprofessional team dimensions (47.32±3.35) compared to the control group ( P<0.001). The experimental group achieved higher scores in objective structured clinical examination skill assessment (81.40±7.22), guiding feedback and reflection (37.50±3.04), and judgmental thinking and clinical reasoning (16.00±2.03) compared to the control group, though the differences were not significant ( P=0.977, 0.668, and 0.636). Conclusions:Interprofessional cooperative simulation enhances the shock patient emergency care abilities and satisfaction with simulation-based teaching for undergraduate nursing students.

Background Exposure to diisononyl phthalate (DINP), an endocrine disruptor associated with metabolic diseases and widely used in plastic products, has been linked to the development of several adverse health outcomes in the liver, including non-alcoholic fatty liver disease (NAFLD). Objective To investigate the effects and the possible molecular mechanisms of DINP exposure on lipid metabolism in human hepatocellular carcinoma cells (HepG2 cells). Methods First, HepG2 cells were treated with DINP at three time spots (24, 48, and 72 h) and eleven doses (0, 0.003, 0.01, 0.03, 0.1, 0.3, 1, 3, 10, 30, and 100 mmol·L⁻¹). Cell viability were detected using cell counting kit 8 (CCK8). Intracellular lipid deposition was determined by oil red O staining and lipid content detection, and triglyceride (TG) and cholesterol (TC) were further detected. Finally, the mRNA expression levels were detected by fluorescence quantitative PCR, including fatty acid synthesis related genes [acetyl-CoA carboxylase alpha (Accα), fatty acid synthase (Fasn), malonyl-CoA decarboxylase (Mlycd), and sterol regulatory element binding protein 1 (Srebp1)] and β-oxidation related genes [peroxisome proliferator activated receptor alpha (Pparα), AMP-activated protein kinase (Ampk), carnitine palmitoyltransferase 1A (Cpt-1a), transcription factor A, mitochondrial (Tfam), nuclear respiratory factor 1 (Nrf1), and peroxisome proliferator-activated receptor gamma and coactivator 1 alpha (Pgc1-α)]. Results Compared with the control group (0 mmol·L⁻¹), the no observed adverse effect levels (NOAEL) of HepG2 cell viability were 0.3, 0.1, and 0.1 mmol·L⁻¹ after 24, 48, and 72 h exposure to DINP, respectively, and the corresponding lowest observed adverse effect levels (LOAEL) were 1, 0.3, and 0.3 mmol·L⁻¹, respectively (P<0.05). After exposure to 30 mmol·L⁻¹ and 100 mmol·L⁻¹ DINP for 24 h, the intracellular lipid content, lipid deposition, TG, and TC levels were increased significantly compared with the control group (P<0.01). Compared with the control group, the mRNA expression levels of genes related to fatty acid synthesis, such as Mlycd, Srebp1, Fasn, and Accα, were down-regulated after the 100 mmol·L⁻¹ DINP exposure for 24 h, while the mRNA expression level of Mlycd was up-regulated in the 30 mmol·L⁻¹ group. The β-oxidation related genes such as Ampk, Pparα, and Tfam were up-regulated significantly after the 100 mmol·L⁻¹ DINP exposure, while Cpt-1a mRNA expression level was down-regulated (P<0.05). Conclusion Exposure to DINP at 30 mmol·L⁻¹ and 100 mmol·L⁻¹ can interfere with fatty acid synthesis and β-oxidation in lipid metabolism of HepG2 cells, resulting in lipid deposition.

Objective To explore the construction and practice of an intelligent prevention and treatment system for venous thromboembolism (VTE) in grassroots hospitals. Methods Based on relevant guidelines and expert consensuses on VTE prevention and treatment, domestic and foreign literature was reviewed. A research and development team composed of clinical experts in VTE prevention and treatment, medical and nursing quality management experts, and information engineers conducted investigations and research in surrounding grassroots hospitals. Through evidence-based research and surveys, the team identified relevant business needs, user needs, and functional requirements of grassroots hospitals, and finally formulated a detailed design plan. The main program of system was written in Java. The interface obtained data from the hospital's data platform through Webservice and view interfaces. To prevent issues of repeated data extraction when multiple applications perform time tasks to assess the same patient during later server usage and expansion, the XXL-JOB distributed task scheduling platform was adopted to handle VTE assessments by medical staff. Results After the clinical application of the intelligent VTE prevention and treatment system, the bleeding risk assessment rate increased from 26.20% at the initial system launch in January 2023 to 83.04% by the end of 2023. In January 2023, the implementation rates of mechanical prevention, pharmacological prevention, and combined prevention for medium-to-high-risk VTE patients were 21.39%, 16.39%, and 5.26%, respectively, which increased to 51.75%, 25.50%, and 25.65% in December 2023. Conclusion The VTE prevention and treatment software system developed by grassroots hospitals can improve development efficiency, enhance the clinical practicality of the system, reduce the workload of medical staff, promote standardization and normalization in VTE prevention and treatment, strengthen closed-loop management of medical quality for VTE as a single disease, and effectively improve the prevention and treatment capabilities and levels of VTE within hospitals.

Objective:To evaluate the efficacy of oral levothyroxine on abortion rate and preterm birth rate in pregnant women with thyroid autoimmunity (TAI) and normal thyroid function.Methods:The relevant studies of oral levothyroxine tablets in the treatment of TAI pregnant women were systematically searched in Pubmed, Cochrane, CBM, CNKI, VIP and Wanfang databases. The retrieval period was established until August 2020. Two researchers independently screened the literatures, extracted the data and evaluated the risk of bias in the included study. Meta-analysis was performed using Revman5.3 software.Results:1) Totally six eligible studies were all randomized controlled studies, involving 1427 patients. 2) Compared with control group, the meta-analysis suggests oral levothyroxine tablets cannot effectively reduce the preterm delivery rate and the abortion rate. 3) Further subgroup analysis of the data according to the natural pregnancy group and assisted reproduction group found that oral levothyroxine tablets in natural pregnancy women with TAI can effectively reduce the preterm delivery rate ( RR=0.54, 95% CI=0.31-0.95, P=0.03), but not reduce the abortion rate ( RR=0.86, 95% CI=0.69-1.06, P=0.15). However, oral levothyroxine tablets cannot reduce the abortion rate for TAI women conceived by reproductive technology ( RR=0.80, 95% CI=0.47-1.36, P=0.41). Conclusion:Oral levothyroxine tablets can effectively reduce the premature delivery rate of TAI women who are naturally pregnant, but it is not beneficial to reduce the abortion rate. There is only one study on TAI women who are pregnant with reproductive technology, so it is impossible to evaluate whether this population can benefit from taking levothyroxine tablets. In view of the above results, it is recommended that the two groups of patients be managed separately.
