Based on the theory of the five-body constituents from Huangdi Neijing (Yellow Emperor's Internal Classic), the approach and methods of acupuncture for facial aging are explored. Acupuncture for facial aging can be guided by the concept of the five-body constituents, targeting the facial "skin, flesh, vessels, tendons, and bones", and utilizing five different types of needles-facial needles, needle knives, filiform needles, retaining needles, and elongated needles and filiform needles-to maximize their respective advantages in treating facial aging. Facial needles are applied to the "skin" by selecting facial acupoints or local ashi points (at wrinkle or pigmentation sites). Needle knives are used for the "flesh" to perform longitudinal dredging and transverse dissection of the facial muscle layers. Filiform needles target the "vessels" with needling at Renying (ST9) to improve facial complexion. Retaining needles act on the "tendons" with needling from Taiyang (EX-HN5) to Xiaguan (ST7), and Jiache (ST6) to Daying (ST5), using clockwise twisting to generate a retaining needle sensation and lifting to achieve an overall facial lifting effect.

INTRODUCTION: Ischaemic stroke is a severe complication of dermal filler injections that remains poorly described and understood. This study aims to characterise the clinical features and outcomes of patients who experience strokes following facial dermal filler injections. METHOD: A systematic review and retrospective analysis of ischaemic strokes caused by dermal filler injections and reported over the past 3 decades, were conducted. Cases involving autologous fat were also compared against those that did not. RESULTS: Fifty-five cases from 45 studies were analysed. Their median age was 32 years (18-61), and most were women (49/55, 89%). Injections frequently occurred at the glabella (17/53, 32%) and temples (12/53, 23%), and autologous fat was most often used (33/55, 60%). Half (29/55, 53%) had ocular symptoms at presentation. Hemiparesis/hemiplegia (30/55, 55%) and confusion/ reduced consciousness/alertness (26/55, 47%) were the predominant stroke symptoms. Most infarcts were unilateral (45/54, 83%) and large (32/48, 67%). Treatment primarily involved corticosteroids (12/41, 29%) and antiplatelet agents (11/41, 27%), while hyaluronidase injections (3/41, 7%) and hyperbaric oxygen therapy (2/41, 5%) were rarely used. Less than half (22/55, 40%) experienced good functional recovery. Those injected with autologous fat were likelier to be symptomatic from their strokes (100% versus [vs] 68%, P=0.0012), develop larger strokes (93% vs 24%, P<0.0001) and experience non-ambulatory outcomes (44% vs 73%, =0.0381). CONCLUSION Strokes are rare complications of dermal fillers. Injections using autologous fat risk larger strokes and worse ambulatory outcomes. An hour of post-procedural observation appears reasonable, and those with ocular complications should undergo brain imaging even in the absence of stroke symptoms.

Heart rate is a crucial indicator of human health with significant physiological importance. Traditional contact methods for measuring heart rate, such as electrocardiograph or wristbands, may not always meet the need for convenient health monitoring. Remote photoplethysmography (rPPG) provides a non-contact method for measuring heart rate and other physiological indicators by analyzing blood volume pulse signals. This approach is non-invasive, does not require direct contact, and allows for long-term healthcare monitoring. Deep learning has emerged as a powerful tool for processing complex image and video data, and has been increasingly employed to extract heart rate signals remotely. This article reviewed the latest research advancements in rPPG-based heart rate measurement using deep learning, summarized available public datasets, and explored future research directions and potential advancements in non-contact heart rate measurement.

Multi-task learning (MTL) has demonstrated significant advantages in the field of physiological signal measurement. This approach enhances the model's generalization ability by sharing parameters and features between similar tasks, even in data-scarce environments. However, traditional multi-task physiological signal measurement methods face challenges such as feature conflicts between tasks, task imbalance, and excessive model complexity, which limit their application in complex environments. To address these issues, this paper proposes an enhanced multi-scale spatiotemporal network (EMSTN) based on Eulerian video magnification (EVM), super-resolution reconstruction and convolutional multilayer perceptron. First, EVM is introduced in the input stage of the network to amplify subtle color and motion changes in the video, significantly improving the model's ability to capture pulse and respiratory signals. Additionally, a super-resolution reconstruction module is integrated into the network to enhance the image resolution, thereby improving detail capture and increasing the accuracy of facial action unit (AU) tasks. Then, convolutional multilayer perceptron is employed to replace traditional 2D convolutions, improving feature extraction efficiency and flexibility, which significantly boosts the performance of heart rate and respiratory rate measurements. Finally, comprehensive experiments on the Binghamton-Pittsburgh 4D Spontaneous Facial Expression Database (BP4D+) fully validate the effectiveness and superiority of the proposed method in multi-task physiological signal measurement.

OBJECTIVE: To explore the technical key points and effectiveness of the facial artery perforator myomucosal flap (FAPMF) in repairing oral and perioral tissue defects. METHODS: Between June 2023 and December 2024, 8 patients with oral and perioral tissue defects were repaired with the FAPMF. There were 4 males and 4 females, with an average age of 57.6 years (range, 45-72 years). Among them, 4 cases had floor-of-mouth defects and 3 cases had buccal mucosa defects remaining after squamous cell carcinoma resection, and 1 case had lower lip defect caused by trauma. The size of tissue defects ranged from 4.5 cm×3.0 cm to 6.0 cm×5.0 cm. The preoperative mouth opening was (39.55±1.88) mm, and the preoperative swallowing score of the University of Washington Quality of Life Questionnaire (UW-QOL) was 64.64±8.47. Preoperatively, CT angiography and Doppler ultrasound were used to locate the perforator vessels. A myomucosal flap pedicled with the perioral perforators of the facial artery was designed, with the harvesting size ranging from 4.0 cm×2.5 cm to 6.5 cm×4.0 cm. The length of the vascular pedicle was 4.2-6.8 cm (mean, 5.2 cm). Postoperatively, FAPMF survival, complications, and functional recovery were observed. RESULTS: All 8 surgeries were successfully completed without conversion to other repair methods or complications such as facial nerve injury. The total operation time ranged from 110 to 180 minutes, with an average of 142.5 minutes; among this, the harvesting time of the FAPMF ranged from 35 to 65 minutes, with an average of 48.7 minutes. The intraoperative blood loss was 50-150 mL, with an average of 85.6 mL. All FAPMFs survived completely. One patient developed venous reflux disorder at 24 hours after operation, which relieved after conservative treatment. All patients were followed up 7-16 months (mean, 12.4 months). All FAPMFs achieved complete epithelialization at 3 months after operation, showing a similar soft texture to the surrounding mucosa. At 7 months after operation, the mouth opening was (39.11±1.79) mm, slightly lower than preoperative level, but the difference was not significant (P>0.05). The swallowing score of the UW-QOL was 63.78±8.31, which was significantly lower than preoperative score (P<0.05). The visual analogue scale (VAS) score for patient satisfaction was 7-10, with an average of 8.9. CONCLUSION The FAPMF has advantages such as reliable blood supply, high mucosal matching degree, and concealed donor site, making it an ideal option for repairing small and medium-sized oral and perioral tissue defects.

Patient 1, a 3-year-6-month-old male, presented with feeding difficulties and delayed motor development. He exhibited poor responsiveness at birth, weak crying, intellectual and motor delays, low immunity, recurrent respiratory infections, hypotonia of the limbs, and distinctive facial features (low-set ears, double chin, and high arched palate), as well as a single transverse palmar crease on the right hand. Genetic testing revealed a c.1096C>T heterozygous variant in the SMARCB1 gene. Patient 2, a 3-year-old male, presented with developmental delay and distinctive facial features. Genetic testing identified the same pathogenic mutation as in Patient 1. The two patients are unrelated, and clinical phenotyping and genetic testing confirmed both cases as Coffin-Siris syndrome type 3. Coffin-Siris syndrome is a rare genetic disorder, and early genetic testing can aid in diagnosis.

BACKGROUND: The protective effectiveness of an N95 respirator depends on the filtration efficiency of the material from which the N95 respirator is made of, as well as the wearers' facial fit. The facial fit of an N95 respirator mainly depends on the degree of matching between the wearers' facial dimension characteristics and the N95 respirator. Quantitative fit testing objectively evaluates the fit of N95 respirators; however, it is not easy to promote because of the limitations of testing conditions. The aim of this study is to establish a fit prediction model of N95 respirator based on facial images. METHODS: Facial images and fit factor (FF) value of 5 N95 respirators were gathered from 299 medical staffs in 10 hospitals in Beijing. Face geometry measurement was based on 3D face modelling, and the American TSI-8038 Porta Count Pro+ was used to conduct quantitative fit test. Multiple linear regression analysis was employed to identify facial dimensional features that significantly influenced the fit of N95 respirators. Through matching training of facial image and FF values, a fit prediction model has been established, enabling rapid recommendation of N95 respirators meeting the fit standard via facial image recognition. RESULTS: A fit prediction model for N95 respirators based on facial images has been developed, which enables the rapid recommendation of N95 respirators with acceptable FF value for healthcare personnel. The model demonstrated an accuracy of 55.93%, a precision of 98.43%, a recall of 51.65%, and an F1 score of 0.68. CONCLUSIONS It is feasible to utilize computer-based facial recognition technology to rapidly recommend N95 respirators for medical personnel. Given the high level of accuracy achieved, the model demonstrates significant potential for practical application.

OBJECTIVE: To establish a similarity measurement model for patients with dentofacial deformity based on 3D craniofacial features and to validate the similarity results with quantifying subjective expert scoring. METHODS: In the study, 52 cases of patients with skeletal Class Ⅲ malocclusions who underwent bimaxillary surgery and preoperative orthodontic treatment at Peking University School and Hospital of Stomatology from January 2020 to December 2022, including 26 males and 26 females, were selected and divided into 2 groups by sex. One patient in each group was randomly selected as a reference sample, and the others were set as test samples. Three senior surgeons rated the similarity scores between the test samples and the reference sample. Similarity scores ranged from 1 to 10, where 1 was completely different, and 10 was exactly the same. Scores larger than 7.5 was considered as clinically similar. Preoperative cone beam computed tomography (CBCT) and 3D facial images of the patients were collected. The three-dimensional hard and soft tissue features, including distances, angles and 3D point cloud features were extracted. The similarity measurement model was then established to fit with the experts' similarity scoring by feature selection algorithm and linear regression model. To verify the reliability of the model, 14 new patients were selected and input to similarity measurement model for finding similar cases. The similarity scoring of these similar cases were rated by experts, and used to evaluate the reliability of the model. RESULTS: The similarity metric models indicated that the features of the middle and lower craniofacial features were the main features to influence the craniofacial similarity. The main features that were related to the expert' s similarity scoring included distance of anterior nasal spine-menton (ANS-Me), distance of right upper canion point-Frankfurt horizontal plane (U3RH), distance of left superior point of the condyle-left gonion (CoL-GoL), distance of left gonion-menton (CoL-Me), distance of pogonion-midsagittal plane (Pog-MSP), distance of right alar base-left alar base (AlR-AlL), angle of pronasale-soft tissue pogonion-labrale inferius (Pn-Pog' -Li), distance of trichion-right tragus (Tri-TraR), distance of left exocanthion-left alar base (ExL-AlL), lower 1/3 of skeletal face, middle and lower 2/3 of skeletal face and upper lip region of soft tissue. Fourteen new patients were chosen to evaluate the model. The similar cases selected by the model had an average experts' similarity scoring of 7.627± 0.711, which was not significantly different with 7.5. CONCLUSION The similarity measurement model established by this model could find the similar cases which highly matched experts' subjective similarity scoring. The study could be further used for similar cases retrieval in skeletal Ⅲ malocclusion patients.
