Spine fracture and dislocation are common traumatic spinal conditions that often require surgical intervention due to compromised spinal stability. Surgical approaches include anterior, posterior, and combined anterior-posterior spinal procedures. According to the specific surgical requirements, patients may be placed in the prone position or repositioned between prone and supine positions during surgery. Intraoperative repositioning has become an essential step in patient positioning. However, during repositioning, patients with spinal fracture and dislocation are at increased risk for complications such as hemodynamic instability, nerve injury, and pressure injuries to the skin and soft tissue. Notably, due to the instability of the spinal cord, even minor manipulations can further exacerbate the damage, potentially leading to severe outcomes like paraplegia. Although the current clinical guidelines provide instructive recommendations for standard position, there remains no specific protocols for intraoperative repositioning in patients with spine fracture and dislocation. With a concern for the lack of clinical studies on positioning techniques, risk prevention, and operational norms for special patients, no applicable guidelines or standards are available. A consensus was required to provide clinical reference, meet the requirements of surgical treatment, and minimize the safety risks of patients caused by improper placement of positions. Professional Committee of Operating Room Nursing of Shaanxi Nursing Association organized experts in nursing management and operating room nursing from major hospitals across China to formulate Expert consensus on intraoperative repositioning for patients with spinal fracture and dislocation ( version 2025). The consensus provides 11 recommendations covering pre-repositioning preparation, intraoperative maneuvers, and post-repositioning observation, aiming to provide references for clinical standardization of the intraoperative repositioning process and protection of patients′ safety.

This review summarizes the applications and advancements of artificial intelligence(AI)in the analysis of retinal vascular parameters. Retinal vascular parameters, including vessel diameter, fractal dimension, vascular tortuosity, branching angles, and vessel density, are important indicators for assessing changes in the retinal vascular network structure. These parameters are not only related to various ophthalmic diseases but also reflect the conditions of systemic diseases such as diabetes and Alzheimer's disease. This article provides a detailed discussion on the advantages of AI technology in the automated identification and quantification of retinal vascular parameters, particularly in improving measurement efficiency and accuracy, and enabling the early detection and monitoring of various diseases. Additionally, the challenges faced by AI in the analysis of retinal vascular parameters were discussed, such as data standardization and insufficient sample diversity, and proposes directions for future research. By thoroughly analyzing the application of AI in retinal vascular parameter analysis, this article aims to offer new perspectives and methods for clinical diagnosis and early intervention of diseases, holding significant clinical significance and application prospects.

Background Arsenic exposure is a common and important environmental and occupational hazardous factor in China, and arsenic-induced insulin resistance (IR) has attracted widespread attention as a negative health outcome to the population. Objective To explore part of the mechanism of hepatic IR induced by arsenic exposure based on the peroxisome proliferators-activated receptors γ (PPARγ)/ glucose transporter 4 (GLUT4) pathway, and to investigate potential effects of Ginkgo biloba extract (GBE) on hepatic IR induced by arsenic exposure and associated mechanism of action. Methods The target of drug action was predicted by network pharmacology and verified by in vivo and in vitro experiments. In vivo experiments: 48 SPF C57BL/6J male mice were divided into 4 groups, including control group, 50 mg·L⁻¹ NaAsO₂ model group (NaAsO₂), 50 mg·L⁻¹ NaAsO₂+10 mg·kg⁻¹ GBE intervene group (NaAsO₂+GBE), and 10 mg·kg⁻¹ GBE group (GBE), 12 mice in each group. The animals were given free access to purified water containing 50 mg·L⁻¹ NaAsO₂, or given intraperitoneal injection of normal saline containing 10 mg·kg⁻¹ GBE once per week. After 6 months of exposure, blood glucose detection, intraperitoneal glucose tolerance test (IPGTT), and insulin tolerance test (ITT) were performed. Serum and liver tissues were collected after the mice were neutralized, liver histopathological sections were obtained, serum insulin levels, liver tissue glycogen content, glucose content were detected by enzyme linked immunosorbent assay (ELISA), and the expression of PPARγ and GLUT4 proteins was detected by Western blot (WB). In vitro experiments: HepG2 cells were divided into 4 groups, including control group, 8 μmol·L⁻¹ NaAsO₂ group (NaAsO₂), 8 μmol·L⁻¹ NaAsO₂ + 200 mg·L⁻¹ GBE intervene group (NaAsO₂+GBE), and 200 mg·L⁻¹ GBE group (GBE). The levels of glycogen and glucose were detected by ELISA, and the expression of PPARγ and GLUT4 proteins was detected by WB. Results A strong binding effect between GBE and PPARγ was revealed by network pharmacology. In in vivo experiments, the NaAsO₂ group exhibited an elevated blood glucose compared to the control group, and the NaAsO₂+GBE group showed a decreased blood glucose compared to the NaAsO₂ group (P<0.01). The histopathological sections indicated severe liver structural damage in the arsenic exposure groups (NaAsO₂ group and NaAsO₂+GBE group), with varying staining intensity, partial liver cell necrosis, and diffuse red blood cell appearance. Both results of in vitro and in vivo experiments showed a decrease in glycogen synthesis and glucose uptake in the NaAsO₂ groups compared to the control groups, which was alleviated in the NaAsO₂+GBE group (P<0.01). The results of WB revealed inhibited PPARγ expression and reduced GLUT4 levels on the cell membrane, and all these changes were alleviated in the NaAsO₂+GBE group (P<0.01). Conclusion This study findings suggest that GBE antagonizes arsenic exposure-induced hepatic IR by regulating the PPARγ/GLUT4 pathway, indicating that GBE has a protective effect on arsenic exposure-induced hepatic IR, and PPARγ may be a potential therapeutic target for arsenic exposure-induced hepatic IR.

Objective To survey the current situation and explore the association between empathic ability and job adjustment disorder of pediatric nurses. Methods The Jefferson scale of empathy health professionals and job adjustment disorder scale were used for the survey among 189 pediatric nurses. Pearson correlation analysis was used to explore the association between empathic ability and job adjustment disorder of pediatric nurses. Results The total score of empathic ability of pediatric nurses was (76.32 ±5.03), the score of their job adjustment disorder was (23.69 ±6.03). Their empathic ability and its dimensions were significantly negatively related with job adjustment disorder (P ＜0.01). Conclusions The empathic ability of pediatric nurses was at a medium to low level, job adjustment disorder was at a medium to high level. The higher level of pediatric nurses' empathic ability, the lower level of job adjustment disorder is. Hospital staff should take measures to improve pediatric nurses' empathic ability, and the pediatric nurses themselves should also actively cultivate their own perception, and improve the empathic ability so as to better acclimatize themselves to pediatric nursing job and reduce the degree of job adjustment disorder.

Primary hepatocellular carcinoma (HCC) is one of the most common malignancies worldwide and has a relatively high mortality rate.Liver transplantation has become an effective treatment for HCCs,but tumor recurrences after liver transplantation and donor shortages are the major limitations.The Milan criterion was the first standard and has been widely applied to liver transplantation of HCCs.Then,there are new emerging standards,namely University of California,San Francisco criterion (UCSF),Hangzhou and Shanghai criteria.Meanwhile,the comparison among these criteria laid the foundation for early prediction and prevention of post-transplantation tumor recurrence.In this review,clinical effect prediction and tumor recurrence after liver transplantation are also heated issues.
