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.

Objective To evaluate the efficacy and safety of high intensity focused ultrasound(HFIU)combined with endometrial ablation in the treatment of adenomyosis(AM)patients with heavy menstrual bleeding(HMB).Method A total of 199 patients with AM combined with HMB who underwent HIFU treatment at the Obstetrics and Gynecology Center of Affiliated Hospital of Chengdu University of TCM from July 2020 to September 2022 were selected and divided into two groups according to the ablation range.The combined ablation group included 80 cases with lesion and endometrial ablation(endometrial ablation rate≥30%),while the lesion ablation group 119 cases with simple lesion ablation.A 1∶1 propensity score matching was performed on the two groups,resulting in 59 patients in each group.A 6-month follow-up was conducted.The clinical manifestations(menstrual volume,degree of dysmenorrhea,uterine and lesion volume),quality of life(MS-QOL,UFS-QOL),and postoperative adverse reactions between the two groups before and 6 months after surgery was compared.Results Menstrual volume,degree of dysmenorrhea,uterine and lesion volume,MS-QOL score,and UFS-QOL score of the both groups were improved 6 months after surgery,when compared to those before surgery(P<0.05).Significantly reduced menstrual volume,degree of dysmenorrhea,and lower MS-QOL score were observed in the combined ablation group when compared with the lesion ablation group(P<0.05),but there was no statistical significance in uterine and lesion volume and UFS-QOL score(P>0.05).There was no difference in the incidence of adverse reactions between the two groups(P>0.05),but the combined ablation group had longer vaginal bleeding and fluid flow time(P<0.05).Conclusion The combined HIFU and endometrial ablation can effectively reduce menstrual flow,alleviate dysmenorrhea,and improve quality of life in patients with AM combined with HMB.Although it increases vaginal bleeding and fluid flow time,reasonable symptomatic management can effectively prevent the occurrence of adverse consequences such as infection.

OBJECTIVE To explore whether Yinjia tablets improve infertility in rats with chronic salpingitis by correcting the peripheral blood Th17/Treg balance. METHODS One hundred female Wistar rats, 82 of which were constructed as a rat model of chronic salpingitis. After successful modeling, the rats were randomly divided into model group, levofloxacin group (20 mg·kg-1), low-dose Yinjia tablets group(0.38 g·kg-1·d-1), medium-dose Yinjia tablets group(0.76 g·kg-1·d-1) and high-dose Yinjia tablets group(1.52 g·kg-1·d-1), 16 rats in each group, and other 16 rats were set up as control group. The treatment groups were administered by gavage at different doses, and the model group and the control group were given the same amount of saline(20 mL·kg-1·d-1), once a day. The gavage was stopped for 1 d after 7 d, and 7 d was one cycle, with a total of 3 cycles of gavage. After administration, the rats were observed for conception and blood samples and oviductal tissues were collected. HE staining was used to observe the pathological changes of fallopian tube tissues; transmission electron microscopy was used to observe the ultrastructural changes of fallopian tube tissues; ELISA was used to detect TNF-α and IL-6 in serum; flow cytometry was used to detect the ratio of Treg and Th17 cells in peripheral blood; RT-qPCR and Western blotting were used to detect IL-17, IL-10, Foxp3, RORγt mRNA and protein expression. RESULTS Compared with the control group, the cilia and microvilli in the model group were sparse and the mitochondria were swollen; the TNF-α and IL-6 contents, the proportion of Th17 cells, and the expression of IL-17 and RORγt mRNA and protein in the oviduct tissues were significantly higher, and the fertility rate, IL-10, the proportion of Treg cells, and the expression of Foxp3 mRNA and protein in the rats were significantly lower(P<0.05). Compared with the model group, the high-dose group of Yinjia tablets improved the structure of oviduct of rats; significantly reduced the TNF-α, IL-6 content, Th17 cell proportion and IL-17, RORγt mRNA and protein expression in oviduct tissue of model rats; and significantly increased the conception rate and IL-10, Treg cell proportion and Foxp3 mRNA and protein expression of rats(P<0.05). CONCLUSION Yinjia tablets can effectively regulate Th17/Treg balance, which in turn regulates Treg and Th17 cell-mediated inflammatory responses and improves the conception rate in chronic salpingitis rats.
