OBJECTIVE: To analyze the prevalence and burden of headache disorders in China and its provinces from 1990 to 2021. METHODS: Using data from the Global Burden of Disease Study (GBD) 2021, the number of prevalent cases, prevalence rate, disability-adjusted life years (DALYs), and age-standardized DALY rates were analyzed by sex, age group, and province for headache disorders and their subtypes (migraine and tension-type headache [TTH]) between 1990 and 2021. Percentage changes during this period were also estimated. RESULTS: In 2021, approximately 426 million individuals in China were affected by headache disorders, with an age-standardized prevalence rate of 27,582.61/100,000. The age-standardized DALY rate for all headache disorders was 487.15/100,000. Between 1990 and 2021, the number of prevalent cases increased by 37.78%, while the prevalence of all headache disorders, migraine, and TTH increased by 6.92%, 7.57%, and 7.86%, respectively. The highest prevalence was observed in the 30-34 age group (39,520.60/100,000). Migraine accounted for a larger proportion of DALYs attributable to headache disorders, whereas TTH has a greater impact on its prevalence. In 2021, the highest age-standardized DALY rates for headache disorders were observed in Heilongjiang (617.85/100,000) and Shanghai (542.86/100,000). CONCLUSION The prevalence of headache disorders is increasing in China. Effective health education, improve diagnosis and treatment are essential, particularly for middle-aged working populations and women of childbearing age.

Objective:To investigate the impact and clinical outcomes of intraoperative prone-position lumbar anteroposterior (AP) fluoroscopy under anesthesia on the selection of the lowest instrumented vertebra (LIV) in the patients with adolescent idiopathic scoliosis (AIS) plus structural lumbar curves.Methods:A retrospective analysis was conducted of the clinical data of 35 patients (29 females and 6 males) with AIS who had undergone surgical posterior correction and fusion at Scoliosis Center, The Third Affiliated Hospital, Sun Yat-sen University between January 2020 and October 2023. The mean age was (17.9±5.7) years. Lenke's classification: 6 cases of type 3, 12 cases of type 4, 7 cases of type 5 and 10 cases of type 6. Preoperatively, all patients underwent standing AP and lateral radiographs of the full-length spine, left and right bending radiographs of the spine, and full-spine CT. Intraoperatively, all patients underwent prone-position lumbar AP fluoroscopy under anesthesia. The criteria for LIV selection were: (1) it should be the most cephalad vertebra touched by the central sacral vertical line (CSVL); (2) its rotation should be ≤ grade Ⅱ by the Nash-Moe classification; (3) its tilt angle should be <25°. The preoperative and postoperative LIV rotation angles were compared, and the number of lumbar fusions was compared between preoperative planning and actual surgery. Comparisons were also made between preoperation, postoperation and the final follow-up, examining Cobb angle of the major curve, Cobb angle of the minor curve, LIV inclination, coronal balance distance (CBD), sagittal vertical axis (SVA), and distance between CSVL and LIV (CSVL-LIV). The correction rates of the major curve and the minor curve, and change in LIV inclination were compared between postoperation and the final follow-up.Results:The patients were followed for (18.0±3.0) months. The LIV rotation decreased from 8.34°±4.95° preoperatively to 5.03°±2.99° postoperatively. The intraoperative fluoroscopy reduced at least one segment fusion for 57.1% (20/35) of the patients so that the number of lumbar fusions decreased significantly from 4.2±0.7 in preoperative planning to 3.6±0.8 after actual surgery ( P<0.05). The Cobb angles of the major and minor curves, LIV inclination, and CSVL-LIV at postoperation and the final follow-up were significantly lower than the preoperative values ( P<0.05), but there were no significant differences between the final follow-up and postoperation in the Cobb angle of the major cure, Cobb angle of the minor curve, or LIV inclination ( P>0.05). None of the patients required surgical revision for distal junctional complications. Conclusions:In the surgical treatment of AIS patients with structural lumbar curves, compared to the preoperative X-rays using the same criteria, intraoperative prone-position lumbar AP fluoroscopy under anesthesia can not only be a safe and effective method for LIV selection but also effectively reduce the number of lumbar fusions to preserve more lumbar mobility.

Objective:To investigate the safety and efficacy of low negative pressure fat suction combined with bipolar radiofrequency in repairing facial fat overfilling.Methods:A total of 29 patients with facial fat overfilling underwent low negative pressure fat suction combined with bipolar radiofrequency between February 2022 and October 2023 in Changsha My Like Medical Cosmetology Hospital. All patients were female. The mean age was 35.7 years (range, 25-51 years) and the mean body mass index was 20.3 (range, 16.8-24.3 kg/cm 2). The mean time after autologous fat transplantation was 53.4 months (range, 19-96 months). Postoperative patient satisfaction surveys were conducted, and 2 independent doctors evaluated clinical effect preoperative and postoperative photographs at 3-6 months postoperatively. Results:There were 29 cases (100%) underwent liposuction in the pre-zygomatic region, and the amount of fat was 4.1-12.6 (7.95±1.85) ml. There were 4 cases (13.8%) underwent liposuction in the forehead, and the amount of fat was 1.8-5.2 (2.75±0.50) ml. There were 7 cases (24.1%) underwent liposuction in the temporal region, and the amount of fat was 2.8-6.5 (3.86±1.07) ml. There were 8 cases (27.6%) underwent liposuction in the cheek, and the amount of fat was 5.2-10.5 (7.25±2.12) ml. There were 18 cases (62.1%) underwent liposuction in the perioral region, and the amount of fat was 3.7-9.5 (6.33±1.28) ml. The energy delivered by bipolar radiofrequency was 3.3-10.2 (5.71±2.27) KJ. 82.8% of patients were satisfied with their postoperative effect (24/29 patients). 86.2% of doctors were satisfied with the postoperative effect (25/29 patients). Two out of 29 patients (6.9%) developed irregularity by liposuction.Conclusions:Low negative pressure liposuction combined with bipolar radiofrequency can effectively reduce the fat, narrow the tissue gap and improve facial sagging, which is an effective method for repairing facial fat overfilling.

Objective:To explore the effect and safety of mesenchymal stem cell exosome microneedle introduction in the treatment of melasma.Methods:Thirty cases of female patients with stable melasma in the Department of Dermatology, Changsha Meilai Medical Beauty Hospital, aged (36±5) years and with a disease duration of (42.4±20.7) months, from July 2021 to July 2022, were retrospectively included. According to Fitzpatrick skin typing, 23 cases of type Ⅲ and 7 cases of type Ⅳ were included. All patients were locally anesthetized with lidocaine cream for 30 min, and rolled with a 0.5 mm needle in a zigzag pattern with even force, in the order of the right cheek, the left cheek, the forehead, the nose, the mandible, and the upper lip. During the rolling process, 3 ml of MSC exosome medical liquid wound dressing was applied to the facial skin, and after it was fully absorbed, exosome was locally readministered in the area of melasma. Treatment ended with a slight redness at the site of application. 1 MSC exosome wound dressing was appllied as a cold compress for 15 min after treatment. Treatment was given once every 2 weeks for 6 consecutive sessions. All the patients were followed up at 4 and 12 weeks after the last session, and the area and severity index of melasma (MASI) were scored before and after the treatment, the clinical efficiency and patient satisfaction rate and the incidence of adverse reactions were also counted.Results:At 4 and 12 weeks after the end of treatment, the skin color of all 30 patients was brighter than that before treatment, and no recurrence of melasma symptoms seen. At 12 weeks after the end of treatment, the decrease rate of MASI score was 66.1%, among which the decrease rate of MASI score in patients with type Ⅲ melasma was 63.9%, and the decrease rate of MASI score in patients with type Ⅳ melasma was 63.9%. Among the 30 patients, 1 case was cured, 25 cases showed obvious improved, 4 cases were improved, and no cases were ineffective, with an effective rate of 86.7% (26/30). Five patients were very satisfied, 18 patients were satisfied, 6 patients were generally satisfied, and 1 patient was dissatisfied; the patient satisfaction rate was 76.7% (23/30). No serious adverse reactions occurred in all patients.Conclusions:MSC exosome microneedle introduction is safe and effective in the treatment of melasma without serious adverse reactions.

OBJECTIVE: To develop a few-shot learning (FSL) approach for classifying optical coherence tomography (OCT) images in patients with inherited retinal disorders (IRDs). METHODS: In this study, an FSL model based on a student-teacher learning framework was designed to classify images. 2,317 images from 189 participants were included. Of these, 1,126 images revealed IRDs, 533 were normal samples, and 658 were control samples. RESULTS: The FSL model achieved a total accuracy of 0.974-0.983, total sensitivity of 0.934-0.957, total specificity of 0.984-0.990, and total F1 score of 0.935-0.957, which were superior to the total accuracy of the baseline model of 0.943-0.954, total sensitivity of 0.866-0.886, total specificity of 0.962-0.971, and total F1 score of 0.859-0.885. The performance of most subclassifications also exhibited advantages. Moreover, the FSL model had a higher area under curves (AUC) of the receiver operating characteristic (ROC) curves in most subclassifications. CONCLUSION This study demonstrates the effective use of the FSL model for the classification of OCT images from patients with IRDs, normal, and control participants with a smaller volume of data. The general principle and similar network architectures can also be applied to other retinal diseases with a low prevalence.
