Tubal ciliary movement is one of the essential transport mechanisms for female fertility, playing a key role in facilitating oocyte pickup and transporting the fertilized ovum. This movement is mediated by multiciliated cells and regulated by specific proteins and hormones that modulate ciliary number, length, polarity, beat frequency, and amplitude to ensure proper function. Genetic mutations, inflammatory stimuli, and hormonal fluctuations can impair ciliary activity or induce ciliary apoptosis, leading to ciliary dysfunction. Disorders of tubal ciliary movement are frequently observed in primary ciliary dyskinesia, pelvic inflammatory disease, polycystic ovary syndrome, and endometriosis, conditions commonly associated with female infertility. These disorders manifest as structural abnormalities of cilia, disrupted polarity, shortened ciliary length, reduced ciliary count, and decreased beat frequency and amplitude. Understanding the role of tubal ciliary movement in female infertility-related diseases, through immunohistochemistry and ultrastructural analysis, helps clarify underlying infertility mechanisms. Identifying abnormal inflammatory factors, hormonal environments, and gene expression, combined with advanced techniques for measuring ciliary protein and beat frequency, may offer novel clinical targets for early prevention and treatment of female infertility.

Paraplegia caused by spinal cord injury is a serious neurological complication, for which surgery is currently the main treatment method. Due to different surgical approaches, patients are usually expected to maintain a passive prone position for a long time or switch between the supine and prone positions. Affected by multiple factors such as neurogenic sensory disorders, pathological changes in muscle tone and operative duration, the risk of intraoperative acquired pressure injury (IAPI) is significantly increased. Current clinical prevention strategies for IAPI in these patients predominantly focus on localized pressure relief during positioning, lacking systematic, standardized comprehensive prevention protocols or evidence-based guidelines. To address it, Department of Nursing, Orthopedics Branch, China International Exchange and Promotive Association for Medical and Health Care, Spinal Trauma Professional Committee, Orthopedics Branch, Chinese Medical Doctor Association, Nursing Group of Spine and Spinal Cord Professional Committee of Chinese Association of Rehabilitation Medicine organized experts in relevant fields to formulate Guideline for the prevention of intraoperative acquired pressure injury in paraplegic patients with spinal cord injury ( version 2025), based on evidence-based medical evidence and latest research results and clinical practice at home and abroad. Eleven recommendations were put forward from the aspects of preoperative risk assessment, intraoperative prevention strategies, postoperative handover and monitoring, and supportive mechanisms for IAPI prevention, aiming to standardize the prevention measures and management strategies of IAPI in paraplegic patients with spinal cord injury and accelerate the recovery of patients and improve the therapeutic effect.

Ocular choristoma is composed of ectopic tissues with normal structures. The pathogenesis still remains uncertain. Histopathologically, it is a dense connective tissue mixed with epidermal appendages, smooth muscle cells, mature adipose tissue, lacrimal glands, lymph nodes, skeletal muscle fibers, cartilage and bone. Because of its low incidence, most of published literature are case reports. The clinical manifestations are non-specific and we need to distinguish it from other ocular masses. The choice of surgical resection depends on the ocular symptoms, the effect on appearance, and the need for clinical confirmation. This paper reviews the epidemiology, etiology, pathogenesis, clinical manifestations, diagnosis, differential diagnosis and treatment of ocular choristoma.

Objective:To develop the Exercise Knowledge and Behavior Questionnaire for Osteoporosis Patients suitable for China, and to test its reliability and validity.Methods:Guided by the theory of knowledge, attitude and practice, a questionnaire framework was constructed, and the first draft of the Exercise Knowledge and Behavior Questionnaire for Osteoporosis Patients was formed through literature review, group discussion, semi-structured interview, Delphi expert consultation and pre-investigation. From June to August 2020, convenience sampling was used to select 120 osteoporosis patients admitted to the First Affiliated Hospital of Soochow University as the research object to conduct a questionnaire survey to test the reliability and validity of the questionnaire. A total of 120 questionnaires were distributed, 110 valid questionnaires were recovered, and the valid recovery rate was 91.67% (110/120) .Results:Among 2 rounds of Delphi expert consultation, the expert authority coefficients were 0.880 and 0.900, respectively, and the Kendall harmony coefficients were 0.308 and 0.332, respectively, with statistically significant differences ( P<0.01) . The Exercise Knowledge and Behavior Questionnaire for Osteoporosis Patients included two sub-questionnaire of knowledge and behavior, with a total of 19 items, including 10 items in knowledge and 9 items in behavior. Exploratory factor analysis showed that 2 common factors were extracted from the exercise knowledge sub-questionnaire, and the cumulative variance contribution rate was 60.712%. A total of one common factor was extracted for the exercise behavior sub-questionnaire, and the cumulative variance contribution rate was 72.075%. The content validity index of the total questionnaire and each sub-questionnaire were 0.925, 0.921, and 0.929, respectively, and the item-level content validity index of was 0.857 to 1.000. The Cronbach's α coefficients of the total questionnaire and each sub-questionnaire t were 0.935, 0.830, and 0.953, respectively, and the split-half reliability coefficients of the total questionnaire and each sub-questionnaire were 0.979, 0.898, and 0.974, respectively, and the test-retest reliability coefficients of the total questionnaire and each sub-questionnaire were 0.878, 0.813, 0.860, respectively. Conclusions:The Exercise Knowledge and Behavior Questionnaire for Osteoporosis Patients has good reliability and validity, and can be used to evaluate exercise knowledge and behavior in patients with osteoporosis.
