Definitive chemoradiotherapy (dCRT) has become a cornerstone in the treatment of locally advanced esophageal cancer; however, local control remains suboptimal, and persistent lesions or locoregional recurrences after treatment are not uncommon. For patients without distant metastases but with local failure, whether surgical intervention can still offer curative potential remains a major clinical dilemma. Salvage esophagectomy (SE) offers potential long-term survival for selected patients, but this procedure is performed in the context of severe fibrosis, impaired local blood supply, and obscured anatomical planes following chemoradiotherapy, resulting in significantly higher perioperative risk compared to primary esophagectomy. Consequently, controversies exist regarding patient selection, preoperative restaging, choice of surgical approach, extent of lymphadenectomy, gastrointestinal reconstruction, and perioperative management. In recent years, with the refinement of restaging modalities such as PET/CT, the accumulation of experience in high-volume centers, and emerging evidence from clinical studies, the clinical role of SE has gradually shifted from a "high-risk salvage measure" to a "selective curative strategy aimed at achieving long-term survival in carefully selected patients". Nevertheless, standardized guidelines for patient selection, technical approaches, and perioperative management are still lacking. Based on current evidence and clinical experience, experts organized by the Integrated Esophageal Cancer Committee of Chinese Anti-Cancer Association systematically reviewed key issues regarding SE, including its definition, indications, preoperative evaluation, choice of surgical approach, lymphadenectomy, gastrointestinal reconstruction, and perioperative management, and formulated a Chinese expert consensus. This consensus aims to provide guidance for standardized assessment, appropriate referral, individualized surgical decision-making, and optimized perioperative management of patients with locoregional failure after dCRT. Ultimately, this will increase the likelihood of R0 resection, reduce the risk of severe complications, and promote the safer, more judicious, and standardized implementation of SE in high-risk scenarios.

In the context of burgeoning economic trade, there has been a remarkable increase in the number of ships travelling between domestic and international ports. Inbound and outbound cargo ships, cruise liners, ferries, and other types of vessels have emerged as critical vehicles for the dispersal of vector organisms and the spread of infectious disease agents. Public health concerns associated with these vessels represent a significant threat to human welfare. In this paper, we comprehensively review the hazards posed by vector organisms on ships, the latest advances in prevention and control strategies, and proposes appropriate countermeasures. The aim is to provide effective guidance for the prevention and control of public health security issues caused by ship-borne vector organisms.

Background: The World Health Organization published the 2019 Integrated Care for Older People (ICOPE) framework to guide, assess, and promote the intrinsic capacity (IC) of older adults, referring to their physical and mental health. This study aims to investigate the relationship between IC and frailty among older adults. Methods: This cross-sectional study was conducted in a medical center in Taiwan in 2021. Two hundred ten patients over 65 admitted to the geriatric ward were invited to participate. The questionnaire included an IC measure, Fried Frailty Scale, and demographic items. The IC measure was ascertained using the six domains of ICOPE (cognition, mobility, nutrition, visual, hearing, and depressive symptoms). The Fried Frailty Scale was used to categorize participants as robust (Fried Frailty Scale=0), prefrail (Fried Frailty Scale=1-2), or frail (Fried Frailty Scale ≥3). Multinomial logistic regression was used to analyze the association between individual ICOPE domains and frailty stages, while adjusting for confounders. Results: Among the participants, 39.0% were prefrail, and 28.6% were frail. Limited mobility and depressive symptoms were significantly associated with prefrail (adjusted odds ratio [aOR]=4.44, 95% confidence interval [CI] 1.82–10.82; aOR=8.41, 95% CI 1.75–40.37) and frail (aOR=11.57, 95% CI 3.63–36.93; aOR=13.77, 95% CI 2.62–72.49) individuals, respectively. Malnutrition (aOR=4.01, 95% CI 1.18–13.62) and hearing loss (aOR=4.37, 95% CI 1.09–19.66) were significantly associated with frail older adults. Conclusion Limited mobility and depressive symptoms occurring at the prefrail stage could be used as assessment items for early detection of prefrail.

Exosomes are ubiquitous in all types of body fluids, exhibiting a high degree of abundance and diversity. Given their distinctive structure and function, exosomes are involved in a range of life activities, including intercellular communication, material transport, and immune regulation. An increasing number of studies have identified exosomes as a source of diagnostic markers for diabetic retinopathy. Furthermore, exosomes represent a novel avenue for therapeutic intervention, with promising clinical applications. This paper examines the diagnostic and therapeutic mechanisms of exosomes in diabetic retinopathy, reviews the advancements in exosomes-based diagnostics and therapeutics for diabetic retinopathy, and aims to enhance the precision and efficiency of clinical diagnosis and treatment of diabetic retinopathy.

Postoperative infection of internal fixation of closed fractures the lower limbs in adults represents a devastating complication, characterized by diagnostic challenges, prolonged treatment duration and high disability rates. Current management of these infections faces multiple challenges, such as difficulties in early accurate diagnosis, and various controversies about the treatment plan, leading to poor overall diagnosis and treatment results. To address these issues, based on evidence-based medicine and principles with emphasis on scientific rigor, clinical applicability and innovation, the Trauma Branch of the Chinese Medical Association, Orthopedic Branch of the Chinese Medical Doctor Association, Orthopedics Branch of the Chinese Medical Association, and Trauma Orthopedics and Polytrauma Group of the Resuscitation and Emergency Committee of the Chinese Medical Doctor Association have collaboratively organized a panel of relevant experts to develop the Guideline for diagnosis and treatment of infection after internal fixation of closed lower limb fractures in adults ( version 2025). The guideline proposed 10 recommendations, aiming to provide a foundation for standardized diagnosis and treatment of postoperative infection in adults with closed lower limb fractures.

Severe open tibiofibular fractures account for approximately 28.1% of all open fractures. Among them, Gustilo-Anderson type IIIB/C fractures present significant clinical challenges due to associated bone and soft tissue defects, high infection rates, and risk of amputation. Inadequate preoperative assessment may lead to suboptimal emergency surgical planning or intraoperative complications. Historically, external fixation was often preferred, but this approach has been associated with limitations such as restricted joint mobility, delayed bone union, joint stiffness, and disuse osteoporosis, resulting in poor functional recovery. With advancements of debridement techniques, standardization of antibiotic use, and popularization of early soft tissue coverage, early internal fixation has gained broader acceptance. Nevertheless, controversies persist regarding the choice of fixation method, timing of definitive fixation, use of reamed versus unreamed intramedullary nailing, and necessity of fibular fixation. To standardize the diagnosis and early management of severe open tibiofibular fractures, reduce complication rates, and improve functional recovery, the Society of Microsurgery of the Chinese Medical Association organized a panel of domestic experts to develop the Evidence-based guideline for the diagnosis and early fixation of severe open tibiofibular fractures ( version 2025), using evidence-based methodology. The guidelines provided 12 recommendations covering diagnostic and early fixation strategies of severe open tibiofibular fractures, aiming to provide clinicians with scientifically grounded and standardized guidance.

Objective:To investigate the effects of thoracolumbar vertebral fracture with incomplete spinal cord injury on male sexual function and postoperative prognosis.Methods:A retrospective review was conducted on data from 144 male patients with thoracolumbar vertebral fractures and incomplete spinal cord injuries treated between May 2009 and May 2021 in the Department of Traumatology and Orthopedics at Peking University Third Hospital. Patients ranged in age from 19 to 55 years (mean: 38.6±10.6 years) and underwent posterior incision and reduction internal fixation. The International Index of Erectile Function-5 (IIEF-5), the Premature Ejaculation Diagnostic Tool (PEDT), and the International Spinal Cord Injury Male Sexual Function Basic Data Set were used for sexual function evaluation. Based on the American Spinal Injury Association (ASIA) Spinal Cord Injury classification, changes in neurological and sexual function were assessed at the pre-injury stage, 3 months post-injury, 2 years postoperatively, and at the final follow-up. Factors influencing sexual dysfunction and recovery were analyzed. Spearman correlation analysis was used to identify factors affecting sexual function injury and recovery.Results:A total of 117 patients were included in the final analysis. Follow-up duration ranged from 26.2 to 161.7 months (mean: 74.6±40.5 months). After injury, ASIA grades were distributed as follows: 43 patients with grade B, 41 with grade C, and 33 with grade D. At the 2-year follow-up, 30 patients were grade E, 63 grade D, 19 grade C, and 5 grade B. Improvement in ASIA classification was observed in 90.6% (106/117) of patients: 79 improved by one grade, 27 by two grades, 8 remained unchanged, 1 worsened by one grade, and 2 worsened by two grades. Mean IIEF-5 scores were 19.5±6.4 pre-injury, 8.7±8.0 at 3 months post-injury, and 17.5±7.1 at 2 years postoperatively, with statistically significant differences ( F=123.247, P<0.001). Differences between 3 months post-injury vs. pre-injury and 2 years postoperatively vs. 3 months post-injury were statistically significant ( P<0.05). Mean PEDT scores were 5.3±3.1 pre-injury, 6.9±5.2 at 3 months post-injury, and 6.4±5.1 at 2 years postoperatively, with statistically significant differences ( F=17.014, P<0.001). The difference between 3 months post-injury and pre-injury was statistically significant ( P<0.05), but not between 2 years postoperatively and 3 months post-injury ( P>0.05). At the 2-year follow-up, 96 patients had their IIEF-5 classification restored to pre-injury levels, 85 restored PEDT classifications, and 83 restored both. Post-injury ASIA classification was positively correlated with a decrease in IIEF-5 score and an increase in PEDT score at 3 months post-injury ( P<0.05). Injury segment was positively correlated with the decrease in IIEF-5 score ( P<0.05). Time from injury to surgery showed a positive correlation with increased PEDT score at 3 months ( P<0.05). Post-injury ASIA grade, injury segment, time to surgery, age, intraoperative decompression, and spinal cord function recovery all showed significant correlations with changes in IIEF-5 and (or) PEDT scores at 2 years postoperatively ( P<0.05). According to the International Spinal Cord Injury Male Sexual Function Basic Data Set, the proportion of patients willing to discuss sexual issues increased from 29.9% at 3 months post-injury to 47.9% at 2 years postoperatively ( P<0.05). The proportion of patients with absent or diminished psychogenic erections remained stable (48.7% vs. 48.9%, P>0.05), while those with normal reflexive erections increased from 34.2% to 65.0% ( P<0.05). Conclusion:Thoracolumbar fractures with incomplete spinal cord injury result in reduced erectile function and increased incidence of premature ejaculation. The degree of spinal cord injury and the level of the injured segment are strongly correlated with the extent of sexual dysfunction. At the 2-year postoperative follow-up, 70.9% of patients had recovered sexual function to pre-injury levels.
