OBJECTIVE To evaluate the long-term cost-effectiveness of insulin degludec and insulin aspart （IDegAsp） in patients with type 2 diabetes mellitus （T2DM） in China. METHODS A cost-effectiveness analysis was conducted from the perspective of the Chinese healthcare system， using the CORE diabetes model to simulate long-term （20-year） health and economic outcomes. Baseline cohort characteristics and treatment effect data were derived from the CREATE study. The prices of glucose- lowering drugs were obtained from medical insurance payment standards and the average winning bid prices in the follow-up round of the specialized centralized procurement for insulin， while the daily dosages were derived from the CREATE study. The costs of complications and utility values were obtained from published literature， with a discount rate of 5%. One-way sensitivity analysis， scenario analysis， and probabilistic sensitivity analysis were performed to verify the robustness of the results. RESULTS Patients switching from previous once-daily basal insulin regimens to IDegAsp therapy gained an incremental 0.190 quality-adjusted life year （QALY） with direct medical cost savings of 42 163.58 yuan. For those switching from premixed insulin therapies， IDegAsp treatment provided 0.130 incremental QALY and reduced direct healthcare costs by 41 129.11 yuan. The outcome was significantly influenced by the discount rate and the cost of complications. Probabilistic sensitivity analysis and scenario analysis confirmed the robustness of these findings. CONCLUSIONS Switching from previous daily basal insulin or premixed insulin regimens to IDegAsp in Chinese patients with T2DM can improve patients’ long-term health outcomes and achieve cost savings， making it a more cost-effective treatment option.

Objective:To analyze the clinical characteristics and treatment outcomes of children with anti-3-hydroxy-3-methylglutaryl-coenzyme A reductase (anti-HMGCR) antibody-mediated necrotizing myopathy, and to explore early identification and management strategies to provide reference for clinical diagnosis and treatment.Methods:A retrospective analysis was conducted on the clinical data and treatment outcomes of 10 pediatric patients with anti-HMGCR antibody-mediated necrotizing myopathy admitted to the Department of Rheumatology, Children′s Hospital of Fudan University from December 2020 to December 2024. Statistical description was performed using SPSS 22.0.Results:Among the 10 patients, the male-to-female ratio was 1:4, the age of onset was (7.2±4.0) years, and the disease duration at diagnosis was (22.2±19.6) months. None had a history of statin exposure. Six patients presented with muscle weakness, and4 were diagnosed due to asymptomatic elevation of creatine kinase (CK); 4 had dermatomyositis-like rashes. All patients showed significantly elevated CK levels [median 3 291(1 969, 8 776)U/L] and underwent muscle biopsy. Histopathological findings revealed myofiber degeneration, necrosis, and regeneration in all cases, with inflammatory infiltration in 9 cases, MHC-Ⅰ positivity in all, and C5b-9 positivity in 9 cases. The median follow-up duration was (15.7±6.3) months. At the last follow-up, muscle strength was normal or nearly normal, and the CK median value had decreased to 977.5 (211.0, 3 536.0) U/L.Conclusion:For patients with suspected idiopathic inflammatory myopathy and significantly elevated CK, muscle-specific antibody testing-including anti-HMGCR-and muscle biopsy should be performed promptly regardless of the presence of skin rash, to ensure accurate diagnosis and guide treatment, thereby avoiding misdiagnosis or missed diagnosis.

Objective:To explore the mediating effect of intrinsic motivation of nurses between empowering leadership and job performance, with the aim of providing a reference basis for managers to develop a scientific and effective intervention programme to improve nurses′ job performance.Methods:Convenience sampling method was used to select 1 213 clinical nurses from four tertiary general hospitals in Shandong Province, Henan Province, Yunnan Province, and Fujian Province from November to December 2023, and General Information Questionnaire, Empowering Leadership Scale, Intrinsic Motivation Scale, and Job Performance Scale were used to conduct a cross-sectional survey. AMOS26.0 software was used to test the mediating effect of intrinsic motivation of nurses between empowering leadership and job performance.Results:A total of 1 100 nurses completed the survey finally. Among them, there were 58 males and 1 042 females, 474 under 31 years old, 448 between 31-40 years old, and 178 over 40 years old.The total scores of the Empowering Leadership Scale, Intrinsic Motivation Scale, and Job Performance Scale were 49.44 ± 10.04, 82.35 ± 13.54 and 46.27 ± 6.20 in that order. Nurses' job performance were positive correlation with the empowered leadership and intrinsic motivation ( r=0.486, 0.703, both P<0.01), there was a positive correlation between nurse empowerment leadership and intrinsic motivation ( r=0.452, P<0.01). Nurses′ intrinsic motivation partially mediates the relationship between empowering leadership and job performance, accounting for 62.69% of the total effect. Conclusions:Intrinsic motivation of nurses is a mediating variable between empowered leadership and job performance. Nursing managers should focus on nurses' participation in autonomous decision-making to enhance nurses′ sense of competence and meaning at work, and mobilise their motivation to improve job performance.

Objective To explore the effect of perioperative nutritional support chain management on the postoperative nutritional status and nutrition knowledge-attitude-practice level of patients with gastric cancer. Methods A total of 162 gastric cancer patients were divided into control group with 82 cases (admitted from June to December 2021) and intervention group with 80 cases (admitted from January to June 2022) according to their admission time. The control group received routine perioperative nutritional management, while the intervention group received nutritional support chain management. The nutritional status and nutrition knowledge-attitude-practice level were compared between the two groups at one month after surgery. Results The proportion of patients with total protein < 60 g/L in the intervention group at one month after surgery was 5.00%, which was lower than 14.63% in the control group; the proportion of patients with albumin < 35 g/L in the intervention group at one month after surgery was 3.75%, which was lower than 13.41% in the control group; the proportion of patients with normal body mass index (BMI) in the intervention group at one month after surgery was 83.75%, which was significantly higher than 59.75% in the control group (P < 0.05). The scores of nutrition knowledge, support attitude and support behavior as well as the total nutrition knowledge-attitude-practice score in the intervention group at one month after surgery were significantly higher than those in the control group (P < 0.05). Conclusion Implementation of perioperative nutritional support chain management can effectively increase the patient's nutrition intake, improve the postoperative nutritional status of gastric cancer patients, and enhance their nutrition knowledge-attitude-practice level and quality of life.

OBJECTIVE To develop a questionnaire of the Knowledge-Attitude-Practice （KAP） for patients receiving oral anticoagulant therapy. METHODS Under the guidance of the theory of KAP， literature analysis and interview method were used to design the initial KAP questionnaire for patients treated with oral anticoagulants. Delphi method was adopted to consult the initial questionnaire and modify the questionnaire based on expert suggestions to form the final questionnaire. RESULTS Two rounds of consultation were conducted with 18 experts， and 18 questionnaires were sent out and recovered in each round， so the positive coefficient of experts was 100%. The expert authority coefficient was 0.94. The average importance scores for all dimensions， factors， and items of the questionnaire in both rounds were ≥4 points. The coefficient of variation was ≤0.25. The Kendall’s concordance coefficient for the overall questionnaire and the three dimensions of knowledge， attitude， and practice ranged from 0.09 to 0.34 （all P＜0.05）. Following the first round of expert consultation， four items were modified， two items were deleted， and five items were added； after the second round of expert consultation， ten items were modified. The final version of the questionnaire included three dimensions （knowledge， attitudes， and practice）， 17 questionnaire factors， and 40 items. CONCLUSIONS The questionnaire has high reliability and scientific validity with relatively concentrated expert opinions. It is suitable for assessing the knowledge， attitudes， and practice status of patients receiving oral anticoagulant therapy.

Objective To investigate the effect of Yigong San(YGS)on learning and memory abilities of rats with lipopolysaccharide(LPS)-induced cognitive decline and explore its possible mechanism in light of intestinal microbiota.Methods Forty SD rats were randomly divided into control group,model group,donepezil(1.3 mg/kg)group,and high-dose(5.25 g/kg)and low-dose(2.63 g/kg)YGS treatment groups.After 24 days of treatment with the corresponding drugs or water by gavage,the rats in the latter 4 groups received an intraperitoneal injection of LPS(0.5 mg/kg)to establish models of Alzheimer's disease(AD).Water maze test and HE staining were used to evaluate the changes in learning and memory abilities and pathomorphology of the hippocampus.The changes in gut microbial species of the rats were analyzed with 16S rRNA sequencing,and the levels of IL-6,TNF-α,and IL-1β in the brain tissue and serum were detected using ELISA.Results Compared with the AD model group,the YGS-treated rats showed significantly shortened escape latency on day 5 after modeling,reduced neuronal degeneration and necrosis in the hippocampus,lowered pathological score of cell damage,and decreased levels IL-6,TNF-α and IL-1β in the brain tissue and serum.The YGS-treated rats showed also obvious reduction of Alpha diversity indicators(ACE and Chao1)of intestinal microbiota with significantly increased abundance of Prevotellaceae species at the family level and decreased abundance of Desulfovibrionaceae,which were involved in such metabolic signaling pathways as cell community prokaryotes,membrane transport,and energy metabolism.Conclusion YGS improves learning and memory abilities and hippocampal pathomorphology in AD rat models possibly by regulating the abundance of intestinal microbial species such as Prevotellaceae to affect the metabolic pathways for signal transduction,cofactors,and vitamin metabolism.

Objective To explore the mechanism by which Yigong San(YGS)improves learning and memory abilities of APP/PS1 transgenic mice in light of cerebral fluid metabolism regulation.Methods Three-month-old male APP/PS1 transgenic mice and wild-type C57BL/6 mice were both randomized into control group,model group,donepezil(1.67 mg/kg)group,and YGS(7.5 g/kg)group and received the corresponding treatments via gavage once daily for one month.After the treatments,the mice were assessed for learning and memory functions using Morris water maze test and examined for hippocampal and cortical pathologies and amyloid plaques using HE,immunohistochemical and thioflavin S staining;ELISA and Evans blue method were used for detecting Aβ1-40 and Aβ1-42 levels in the brain tissue and serum and assessing blood-brain barrier(BBB)integrity.Immunofluorescence colocalization was used to investigate AQP4 polarization on astrocytes.Western blotting was performed to detect the expressions of VE-cadherin,ZO-1,occludin,β-amyloid precursor protein(APP),BACE1,insulin-degrading enzyme(IDE),LRP1,RAGE,and AQP4 proteins.Results Compared with the control mice,APP/PS1 mice showed significant impairment of learning and memory abilities,increased degeneration or necrosis of hippocampal and cortical neurons,pathological scores,Aβ-positive plaques,elevated Aβ1-40 and Aβ1-42 levels in the brain tissue and serum,increased BBB permeability,upregulated RAGE expression,lowered expressions of VE-cadherin,LRP1,ZO-1,occludin,and AQP4 proteins,and reduced AQP4-expressing GFAP-positive cells.YGS treatment significantly improved the performance of the transgenic mice in Morris water maze test,reduced hippocampal and cortical pathologies and Aβ-positive plaques,and ameliorated the abnormal changes in Aβ1-40 and Aβ1-42 levels,BBB permeability,protein expressions of RAGE,VE-cadherin,LRP1,ZO-1,occludin and AQP4,and the number of AQP4-expressing GFAP-positive cells.Conclusion YGS improves learning and memory changes in APP/PS1 mice by ameliorating neuronal damage and Aβ pathology in the brain and regulating brain fluid metabolism.
