Objective To construct a global model of cardiac surface motion based on average intensity projection(AIP)image.Methods The cine magnetic resonance imaging data were divided into training set and test set for model construction and validation.The datum points were obtained on the AIP surface point cloud,and the corresponding points of each cardiac phase surface point cloud were found based on surface features.Principal component analysis was used to extract feature information,establish the mapping relationship between the datum points and the corresponding points,and construct a model for predicting each temporal phase surface point cloud from the AIP surface point cloud.Results The RMSE of the model on test set for corresponding point prediction ranged from(0.209±0.020)mm to(0.841±0.074)mm,while the Euclidean distance for each time phase surface point cloud prediction ranged from(1.399±0.029)mm to(1.658±0.100)mm.Conclusion The proposed global model exhibit high accuracy and can provide a reference for image segmentation and clinical treatments.

In recent years, minimally invasive technology has been at the forefront of advancing various disciplines due to its unique advantages. With the development of endoscopic techniques, low-temperature plasma technology, and balloon dilation methods, the application of minimally invasive surgery in pediatric otolaryngology has increased significantly in clinical practice. The primary objective of minimally invasive techniques is to preserve normal anatomical structures as much as possible, reduce tissue damage associated with surgery, lower surgical risks, accelerate postoperative recovery, and achieve surgical outcomes that are comparable to or even better than those obtained through conventional procedures. In the future, the development of minimally invasive surgery must be aimed at pursuing the maximum benefit for patients, and operations will be more scientific, functional, comfortable, and diversified. The author believes that the development of minimally invasive surgery is inseparable from multidisciplinary cooperation, including clinicians, engineers, and other professionals in different fields. Only by working together can we jointly promote the development of minimally invasive surgery technology and provide patients with more accurate, efficient, and safe treatment options.

Objective:To explore the causes and preventive measures of respiratory arrest following general anesthesia in children with obstructive sleep apnea （OSA）, in order to enhance the safety of OSA surgeries under general anesthesia. Methods:A retrospective analysis was conducted on the clinical and follow-up data of four pediatric cases that experienced respiratory arrest after general anesthesia for OSA at Shenzhen Hospital of Southern Medical University from March 2020 to March 2022. Results:All four children exhibited varying degrees of decreased blood oxygen saturation, cyanosis, and loss of consciousness after OSA surgery under general anesthesia, with one case experiencing respiratory and cardiac arrest. Through emergency rescue measures such as oxygen supplementation, suctioning, positive pressure ventilation, awakening, and cardiopulmonary resuscitation, all four children were stabilized. Follow-up after 2 to 6 months showed no complications. The main reasons for the occurrence are analyzed as: residual anesthetic drugs, characteristics of the OSA disease, and the unique aspects of the pediatric population. Conclusion:Children undergoing general anesthesia for OSA should be closely monitored for vital signs after surgery. If respiratory suppression occurs, active rescue measures should be taken to avoid serious consequences.

This case report outlines the treatment of an 11-year-old female who underwent adenotonsillectomy six years ago for snoring but experienced postoperative inefficacy. Her symptoms worsened two weeks before readmission, with increased snoring and sleep apnea, disabling her from lying down to sleep. She was readmitted on December 1, 2023, and diagnosed with severe obstructive sleep apnea hypopnea syndrome and hypercapnia. Automatic BiPAP alleviated her symptoms, with sleep breathing parameters normalizing during treatment. Follow-up at one month showed significant acceleration in her growth and resolution of her hypersomnolence issue.

Drug-induced sleep endoscopy （DISE） is an endoscopic examination performed under conditions similar to human physiological sleep induced by drugs. In recent years, its clinical application has become increasingly widespread. This article reviews the research progress on the indications, anesthesia, and outcome determination of pediatric DISE, providing a basis for the application of pediatric DISE.

Glucocorticoid therapy constitutes an essential and pivotal element in the management of lupus nephritis. Nevertheless, prolonged administration of glucocorticoids may result in systemic toxicities that adversely affect patients' quality of life and elevate mortality rates. Currently, there is a lack of definitive guidelines regarding the timing and methodologies for glucocorticoid tapering. This article aims to summarise the current evidence on glucocorticoid tapering strategies for lupus nephritis from various guidelines and studies to provide enhanced references for clinical practice.

Breast cancer is one of the most common cancers in women,but there is currently a lack of accurate prognos-tic assessment systems.The Naples Prognostic Score(NPS)is a prognostic prediction system that incorporates inflammatory and nutritional indicators.It has been proven to have important clinical utility in predicting the prognosis of patients with malignancies such as colon cancer,gallbladder cancer,endometrial cancer,and lung cancer.In recent years,research has found that NPS may be superior to TNMstaging in predicting the prognosis of breast cancer patients.It is an independent predictor of overall sur-vival(OS)and progression-free survival(PFS)in breast cancer patients.This suggests that NPS has great potential for applica-tion in predicting the prognosis of breast cancer.

Two children with late-onset congenital central hypoventilation syndrome were reported, one of whom was male and had no abnormal manifestations after birth, respiratory failure occurs at the age of 1 year and 6 months. After being hospitalized, he was treated with oxygen inhalation and non-invasive ventilation, but carbon dioxide retention could not be corrected. After one month of tracheal intubation, he was failure to wean from ventilator, so tracheostomy was performed. He needs a ventilator to help breath while sleeping, and can breath autonomously during the day without ventilator. The other case was a female, with no abnormalities after birth. At the age of 11 months, she developed respiratory failure. During sleep, the child needs non-invasive assisted ventilation through a nasal mask, and during the day, she breathed autonomously.Two patients were followed up forever 2 years and their growth and development were normal.
