Diabetes mellitus, characterized by glucose metabolism disorders and marked by insulin deficiency or insulin resistance, has seen a continuous rise in prevalence. In recent years, islet transplantation has matured as a therapeutic approach for diabetes, becoming an important method for glycemic control and the reduction of diabetes-related complications. Donor selection directly influences transplant outcomes, and various research institutions worldwide have proposed multiple scoring systems to optimize donor assessment, such as the University of Alberta scoring system and the North American Islet Donor Score. This article explores the impact of key factors such as donor age, body mass index and ischemia time on islet transplantation. Combining practical experience in pancreatic donor selection from Shanghai Changzheng Hospital, it proposes screening criteria for pancreatic donors suitable for China, aiming to provide new evidence for improving the success rate of islet transplantation.

Objective: There were associations between emotional abuse and neglect (EAN) and depression, but few studies had tested potential mechanisms underlying these relationships. We aimed to provide insights on how (the mediation role of neuroticism), and under what conditions (the moderator role of psychological resilience), led to a higher level of depression. Methods: This study was a cross-sectional study that used a random cluster sampling method. We randomly selected 3,993 participants from four junior middle schools in northern city of China. Participants were asked to complete four self-reported questionnaires, including the Childhood Trauma Questionnaire, Children Depression Inventory-Short Form, Chinese Big Five Personality Inventory Brief Version, and Chinese Resilience Scale. Results: The results showed that neuroticism mediated the associations between EAN and depression. In addition, the mediating effect of neuroticism was moderated by psychological resilience (p<0.05). Conclusion EAN and neuroticism could have an adverse impact on depression, and psychological resilience could alleviate these negative effects as a moderator. Our model suggested psychological resilience could be a particularly effective intervention point for victims of EAN.

OBJECTIVE: To explore the advantages and effectiveness of the independently developed intelligent orthopedic robot-assisted distal locking of femoral intramedullary nails. METHODS: Thirty-two adult cadaveric femur specimens were randomly divided into two groups, with 16 specimens in each group. The experimental group used the intelligent orthopedic robot to assist in the distal locking of femoral intramedullary nail holes, while the control group used the traditional method of manual locking under X-ray fluoroscopy. The locking time, fluoroscopy times, and the success rate of first locking were recorded and compared between the two groups. RESULTS: The locking time of the experimental group was (273.94±38.67) seconds, which was shorter than that of the control group [(378.38±152.72) seconds], and number of fluoroscopies was (4.56±0.81) times, which was less than that of the control group [(8.00±3.98) times]. The differences were significant [ MD=73.054 (-37.187, 85.813), P=0.049; MD=1.969 (-1.437, 2.563), P=0.002]. The first locking success rate of the experimental group was 100% (16/16), which was significantly higher than that of the control group (68.75%, 11/16) ( P=0.043). CONCLUSION The efficiency of distal locking of femoral intramedullary nails assisted by the intelligent orthopedic robot is significantly higher than that of the traditional manual locking method under fluoroscopy, as it can markedly reduce the time required for distal locking of femoral intramedullary nails, decrease intraoperative radiation exposure, and increase the success rate of locking.

OBJECTIVE To evaluate the short-term efficacy of single-session microwave ablation for benign thyroid nodule.METHODS Patients with benign thyroid nodules treated by microwave ablation between June 2019 and December 2022 at the Department of Otolaryngology Head and Neck Surgery,the First Affiliated Hospital of Xi'an Jiaotong University,were included for analysis.Thyroid function was tested 1 month after treatment,and ultrasound and thyroid function were performed 3 months,6 months and 1 year after treatment.Volume reduction rates(VRR)of nodules were calculated.Data of the last follow-up within 1 year were included for analysis.Variables including gender,age,whether Hashimoto's thyroiditis was present,longitudinal diameter of nodules,solid volume of nodules were included for univariate and multivariate analysis.RESULTS A total of 151 patients with 163 nodules were included.The perioperative complication rate was 1.99%(3/151).The VRR at half year after treatment was(79.58±17.70)%,and the success rate at half year after treatment was 93.43%(128/137).The VRR of at 1year after treatment was(81.24±24.29)%.The 1-year treatment success rate was 92.77%(77/83).Univariate and multivariate analysis showed that nodular solid volume and age were independent factors affecting VRR after ablation.Regression coefficient of age and solid volume was 0.34(P<0.05)and-0.47(P<0.05),respectively.For every 1 cm3 increase in solid volume,1-year VRR(%)decreased by 0.47.Regression equation:1-year VRR=68.92+0.34×age-0.47×solid volume.Serum FT4 gradually decreased and the thyroid stimulating hormone(TSH)gradually increased within 6 months after ablation,and the differences were statistically significant(P<0.05).After 6 months,serum FT4 gradually recovered to the normal level and TSH gradually recovered.However,TSH still did not reach the preoperative level one year after ablation.FT3 decreased gradually after treatment,but there was no significant difference between the values at each time point(P=0.40).After the ablation of thyroid nodule,the mean value of thyroid function index fluctuated,but all of them were within the normal reference range.CONCLUSION Microwave ablation is a safe and effective treatment method for benign thyroid nodules,with an overall success rate of over 90%.Solid nodule volume and age are independent factors affecting the microwave ablation effect of benign thyroid nodules.

Objective To explore the effect of motivational interview in the psychological counseling and management abilities of family caregivers of children with recurrent wheezing.Methods A total of 120 children with recurrent wheezing who were treated in Hangzhou Children's Hospital from May 2023 to May 2024 were selected.The family caregivers of children were randomly divided into control group and observation group,with 60 people in each group.The control group received conventional knowledge training and health education,while the observation group received motivational interviews based on control group.Compare the asthma control level,anxiety and depression levels of family caregivers of children,scores of various dimensions of the family caregivers of children management measurement scale,and satisfaction between two groups before and after intervention.Results After intervention,the frequency of recurrent wheezing in observation group was lower than that in control group,and the difference was statistically significant(P＜0.05).There was a statistically significant difference(P＜0.05)in family management measure scores between two groups before and after intervention.The satisfaction of family caregivers of children in observation group was significantly higher than that in control group,and the difference was statistically significant(P＜0.05).Conclusion Motivational interview intervention can effectively alleviate the wheezing frequency of children with recurrent wheezing,improve the response of family care,reduce anxiety and depression of family caregivers of children.

Objective To investigate the protective effect and mechanism of ginsenoside Rg1(G-Rg1)on interleukin-6(IL-6)-induced neuronal injury in rats by regulating Janus activated kinase(JAK)/signal transducer and activator of transcription 3(STAT3)signaling pathway.Methods After culture,rat hippocampal neurons were divided into the control group(normal culture),the IL-6 model group(50 μg/L IL-6 was used to treat rat hippocampal neurons for 18 h to simulate the inflammatory environment in brain),the G-Rg1 low dose(10 μmol/L)group and the G-Rg1 high dose(40 μmol/L)group.After 48 h of normal culture,the survival rate of hippocampal neurons was determined by MTT method.The total iron load of neurons was detected by spectrophotometry,and levels of ferroptosis markers glutathione(GSH)and glutathione peroxidase 4(GPX4)were detected.The mRNA expression level of ferroportin 1(FPN1)in hippocampal neurons was detected by qRT-PCR.The expression of proteins related to the neuronal JAK/STAT3 signaling pathway was detected by Western blot assay.Results Compared with the CON group,the neuronal survival rate,GSH content,GPX4 content and FPN1 mRNA expression level were decreased in the IL-6 model group,and the total iron load,p-JAK and p-STAT3 protein expression levels were increased(P＜0.05).Compared with the IL-6 model group,the neuronal survival rate,GSH content,GPX4 content and FPN1 mRNA expression level were increased in the low-dose and high-dose G-Rg1 groups,and the total iron load,p-JAK and p-STAT3 protein expression levels were decreased(P＜0.05).Changes of the above indicators were more significant in the high-dose G-Rg1 group than those in the low-dose G-Rg1 group(P＜0.05).Conclusion The mechanism of G-Rg1 alleviating ferroptosis of hippocampal neurons in rats may be related to the inhibition of IL-6/JAK/STAT3 signaling pathway,up-regulation of FPN1 expression,and prevention of iron overload.
