Background/Aims: Non-pharmacological treatments are crucial for managing irritable bowel syndrome (IBS), yet patient engagement remains a challenge. Understanding patients' knowledge, attitudes, and practices regarding these treatments is essential for improving care. Methods: A cross-sectional study was conducted across 5 hospitals, from October 2023 to February 2024. A self-designed knowledge, attitudes, and practices questionnaire along with the IBS quality of life and IBS severity scoring system was administered, and 496 valid responses were analyzed. Statistical analyses included correlation tests, multivariate linear regression, and mediation effect analysis. Results: The median scores for knowledge, attitude, and practice were 28, 25.5, and 21, respectively. Significant positive correlations were found between knowledge-attitude (r = 0.195), knowledge-practice (r = 0.364), and attitude-practice (r = 0.151). The multivariate linear regression analysis further indicated that knowledge (β = 0.399, P < 0.001) and attitude (β = 0.219, P = 0.022) positively correlated with the practical performance. SEM revealed that knowledge had a significant direct effect on both attitude (β = 0.186, P = 0.013) and practice (β = 0.356, P = 0.006). However, the direct effect of attitude on practice was not significant, and attitude did not mediate the relationship between knowledge and practice. Conclusions IBS patients exhibit a significant gap between their positive attitudes and their actual practices concerning non-pharmacological treatments. Knowledge is a direct driver of practice, but positive attitudes alone are insufficient to translate into behavior. Healthcare providers must move beyond simply fostering positive attitudes and focus on targeted educational interventions that provide actionable knowledge and skills to improve patient outcomes.

Amoenucles A-F (1-6), six previously undescribed nucleoside derivatives, and two known analogs (7 and 8) were isolated from the culture of Aspergillus amoenus TJ507. Their structures were elucidated through spectroscopic analysis, single-crystal X-ray crystallography, and chemical reactions. Notably, 3 and 4 represent the first reported instances of nucleosides with an attached pyrrole moiety. Of particular significance, the absolute configuration of the sugar moiety of 1-4 was determined using nuclear magnetic resonance (NMR), electric circular dichroism (ECD) calculations, and a hydrolysis reaction, presenting a potentially valuable method for confirming nucleoside structures. Furthermore, 1, 2, and 5-8 exhibited potential tumor necrosis factor α (TNF-α) inhibitory activities, which may provide a novel chemical template for the development of agents targeting autoimmune and inflammatory diseases.

Medical image is a powerful tool to assist doctors in the diagnosis and treatment planning.Nowadays,the segmentation of medical images is no longer limited to manual segmentation methods.Traditional methods and deep learning methods have been used to achieve more accurate results in medical image segmentation.Herein some innovative medical image segmentation methods in recent years are reviewed.By elaborating on the innovations of deep learning methods(SAM,SegNet,Mask R-CNN,and U-NET)and traditional methods(active contour model and threshold segmentation model),the differences and similarities between them are compared.The summary of medical image segmentation methods and the prospect is expected to help researchers better grasp and familiarize themselves with research status and development trend.

Objective:To analyze the efficacy of endoscopic surgical repair in the treatment of type Ⅲ laryngeal clefts and to explore the feasibility of the treatment for type Ⅲ laryngeal clefts. Methods:The clinical data of 6 children with type Ⅲ laryngeal clefts who underwent endoscopic surgical repair in our department from June 2018 to January 2023 were analyzed retrospectively. The operation was performed under combined intravenous and general anesthesia,preserving the spontaneous breathing of the children. With the assistance of 4 mm/0° endoscope, radiofrequency knife or laryngeal scissors were used to make fresh wounds along the edge of laryngeal clefts,and cotton pads infiltrated with adrenaline （1:10 000） were used to compress the wound. 6-0 PDP suture was used to suture 3-6 stitches according to the extent of laryngeal clefts. Modified barium swallowing test （MBS） was performed 3 months after operation. Results:All the children were successfully treated with endoscopic surgical repair. After surgery, 2 cases were transferred to pediatric intensive care unit （ICU） for 7 days of monitoring, and the rest were transferred back to the general ward. There were no postoperative complications. The symptoms of dysphagia, laryngitis and recurrent pneumonia were improved in all children. According to the follow-up results of postoperative MBS,no aspiration was found in all children, and 2 children had intermittent cough when drinking large amounts of water. During the follow-up, there were 2 cases of recurrence, and the cracks were completely repaired after the second endoscopic surgical repair treatment,and no recurrence has been observed so far. Conclusion:Endoscopic surgical repair can be applied to some children with type Ⅲ laryngeal clefts with less intraoperative bleeding and fewer operative complications. It can significantly improve the symptoms such as swallowing dysfunction and recurrent pneumonia. It is a safe and effective surgical treatment.

At present, there is no unified gold standard for the treatment of laryngeal clefts. Type Ⅰ laryngeal clefts with mild symptoms can be treated conservatively, such as thick diet feeding and using proton pump inhibitor to control reflux, while Ⅱ-Ⅳ laryngeal clefts mostly requires surgical intervention.There are many different surgical methods for the treatment of laryngeal clefts, including injection laryngoplasty, endoscopic surgical repair of laryngeal clefts and open laryngoplasty through anterior cervical approach. How to choose a more suitable surgical plan for children is a problem worth discussing. This article will review the literature on the surgical treatment of laryngeal clefts both domestically and internationally, and summarize the current situation and challenges of surgical treatment of laryngeal clefts.

OBJECTIVES: To investigate the effet of nasal septum operation combined with nasal sinuses on postoperative nasal septum. METHOD: Sixty-five patients with deflection of nasal septum complicating chronic sinusitis were underwent nasal septum and nasal sinus operations under nasal endoscope. Postoperative nasal septum recover were observed and compared with patients underwent only simple nasal septum operation. RESULT: Patients underwent nasal septum operations combined with nasal sinus, postoperative symptoms were more serious at early than simple nasal septum operations. At 3 months after operation, satisfactory degree of the former group were higher than the latter, and the former group didn't have complications such as nasal septum infection. CONCLUSION Nasal septum operations combined with nasal sinus have no harmful effect on the prognosis of nasal septum, so it was safe and reliable.
