Hepatic ischemia/reperfusion injury is an important restricting factor of clinical liver resection and liver transplantation.When the liver is transiently deprived of blood followed by repeffusion,a large number of various mediators are released that can lead to cellular and,eventually,organ dysfunction.This review summarizes the pathogenesis and the protection mechanisms of hepatic ischemia/reperfusion injury.

This study aims to systematically review the illness experience of adolescent patients with type 1 diabetes mellitus (T1DM). The JBI qualitative systematic review method was used and meta-aggregate analysis of 14 qualitative studies was performed. Qualitative studies on the disease experience of adolescent patients with T1DM were obtained from Cochrane, PubMed, Web of Science, CINAHL, Embase, Wanfang, CNKI, and VIP, and the search period was from 1995 to 2024. The qualitative research quality evaluation tool of JBI the Evidence-based Health Care Center in Australia was used to evaluate the analysis results. Thirty-one results were distilled and categorized into 7 themes and then synthesized into 3 overarching findings: (1) experiencing psychological distress and developing coping mechanisms following adjustment; (2) acknowledging self-management shortcomings and actively seeking support;and (3) overcoming challenges and growing through experiences. The findings illuminate that adolescents with T1DM often experience negative physical and emotional challenges during their illness.Transitioning from dependency to independence poses numerous obstacles that can be overcome by improving both internal and external support, cultivating self-management skills, strengthening coping mechanisms, and achieving control over the disease while fostering personal growth.

Objective:To evaluate the clinical effects of posterior reduction in the treatment of acute severe traumatic lumbar spondylolisthesis.Methods:A retrospective study was conducted to analyze the clinical data of 12 patients with acute severe traumatic lumbar spondylolisthesis who had been treated by posterior reduction at Department of Spinal Surgery, Zhengzhou Orthopaedic Hospital from June 2010 to December 2018. There were 7 males and 5 females with an age of (25.7±1.8) years. The spondylolisthesis was at L4 in 4 cases and at L5 in 8 cases, and grade Ⅲ in 7 cases, grade Ⅳ in 4 cases and grade Ⅴ in 1 case according to the Meyerding classification. By the American Spinal Injury Association (ASIA) grading, the preoperative neurological function was at level B in 6 cases, at level C in 4 cases, and at level D in 2 cases. All the 12 patients underwent posterior reduction and internal fixation with pedicle screws, as well as intervertebral bone graft fusion. Operation time and intraoperative blood loss were recorded. Clinical efficacy was evaluated by visual analogue scale (VAS) and Oswestry disability index (ODI) before and after surgery, and neurological function was evaluated by ASIA grading. X-ray, CT plain scan and reconstruction were used to observe internal fixation and bone grafting.Results:All patients were followed up for (18.5±2.1) months. The operation time was (165.7±42.3) min and the blood loss (497.7±75.3) mL. The VAS pain scores [(2.7±0.3) points and (1.8±0.2) points] and ODIs (18.2%±2.3% and 14.5%±2.6%) at 2 weeks after operation and at the last follow-up were significantly lower than the preoperational values [(8.5±0.6) points and 72.3%±12.3%] ( P<0.05), but there was no statistically significant difference between 2 weeks after operation and the last follow-up ( P>0.05). At the last follow-up, X-rays and CT scans showed good fixation and adequate bone grafting; the spondylolisthesis was grade 0 in 10 cases and grade I in 2 cases; the ASIA level of neurological function was C in 2 cases, D in 3 cases, and E in 7 cases. Healing of surgical incision was delayed in 2 patients but responded to symptomatic treatment. Follow-ups observed no such complications as loosening or pulling out of internal fixation. Conclusion:In the treatment of acute severe traumatic lumbar spondylolisthesis, posterior reduction can effectively restore the spondylolisthesis sequence and restore spinal stability, leading to satisfactory curative outcomes.

Objective:To evaluate the clinical efficacy of pushing reduction with our self-designed spinal fracture reduction device in the treatment of A3N0/1 thoracolumbar fractures.Methods:A retrospective study was conducted to analyze the medical records of 53 patients who had undergone surgery for thoracolumbar vertebrae fracture at Department of Minimally Invasive Spine Surgery, Zhengzhou Orthopedic Hospital from January 2019 to January 2022. All patients were treated by internal fixation via the Wiltse approach and bone grafting through the pedicle of the injured vertebrae. Clinical data: 35 males and 18 females; age: (37.8±10.2) years; injured segments: 23 cases at the thoracic spine and 30 cases at the lumbar spine; time from injury to surgery: (3.3±1.5) days. According to whether our self-designed spinal fracture reduction device was used or not, the patients were assigned into group A (23 cases) in which the injured vertebrae were pushed and reduced using our novel spinal fracture reduction device after vertebral distraction reduction by the pedicle screw and group B (30 cases) in which the injured vertebrae were distracted and reduced using the pedicle screw alone. The operation time, intraoperative blood loss and complications were compared between the 2 groups. The anterior vertebral body height ratio (AVBHr), middle vertebral body height ratio (MVBHr), posterior vertebral body height ratio (PVBHr), Cobb angle of the injured vertebra, visual analogue scale (VAS) and Oswestry disability index (ODI) at preoperation, postoperative 3 and 6 months, and the last follow-up were compared between the 2 groups.Results:There was no statistically significant difference in the preoperative general data between the 2 groups, indicating comparability ( P>0.05). All patients were followed up for (16.3±5.9) months. All incisions healed at one stage postoperatively without any related complications. The operation time in group A was significantly longer than that in group B [(115.1±16.6) min. versus (101.0±11.5) min.], the intraoperative blood loss in group A was significantly greater than that in group B [(136.5±17.0) mL versus (121.6±19.8) mL], the MVBHr at postoperative 3 months in group A (93.9%±4.0%) was significantly better than that in group B (83.3%±7.6%), and the MVBHr, AVBHr, Cobb angle, VAS, and ODI at the last follow-up in group A [86.6%±5.5%, 89.8%±4.1%, 4°(4°, 6°), 1 (0, 1) point, and 4.7%±2.0%] were significantly better than those in group B [78.0% (74.0%, 79.0%), 84.5%±4.9%, 12.2°±3.3°, 2 (1, 3) points, and 7.3%±2.7%] (all P<0.05). However, there was no statistically significant difference in PVBHr between the 2 groups at postoperative 3 months or at the last follow-up ( P>0.05). Conclusion:In the treatment of A3N0/1 thoracolumbar fractures, pushing reduction with our self-designed spinal fracture reduction device can directly and effectively reduce the fracture zone of the injured vertebra, which is conducive to maintaining postoperative vertebral reduction, reducing vertebral height loss and kyphotic deformity at a later stage, relieving lumbar pain and improving lumbar spine function.
