Occlusal reconstruction is an important method of restoring a normal occlusal relationship to the natural dentition.The cor-rect choice of lateral occlusion scheme is necessary for physiological occlusal reconstruction.The main lateral occlusion schemes for the occlusal reconstruction of the natural dentition are canine protection and group function.This article reviews the effects of lateral occlu-sion schemes on the stomatognathic system and factors affecting the choice of lateral occlusion schemes in the occlusal reconstruction of natural dentition.According to the literature review,the lateral occlusion schemes affect the physiological functions of the stomatognath-ic system.Both lateral occlusion schemes have less impact on the temporomandibular joint.Group function produces greater EMG activi-ty,jaw movement velocity,and jaw lateral freedom than canine protection.The lateral occlusion schemes of the natural dentition should be selected according to the degree of lateral movement,types of static occlusion,and age of patients.For patients with Angle's ClassⅢ malocclusion,skeletal Class Ⅱ,Ⅲ malocclusion,and the elderly,group function is recommended,while canine protection is more recommended for young adults.For patients who eventually need to achieve canine protection,it is recommended to design group func-tion in the early stage of lateral movement,and gradually transition to canine protection with the increase of lateral movement.Thus,clinicians need to fully understand the influencing factors of lateral occlusion selection during occlusal reconstruction in natural denti-tion,providing a basis for the development of personalized diagnostic and treatment plans.

Objective:To explore the needs and feelings of emergency palliative care from the perspective of medical and nursing staff.Methods:Purposeful sampling was used to recruit 23 emergency medical and nursing staff with experience in end-of-life care from two Class Ⅲ Grade A hospitals in Wenzhou City between September and October 2024. Semi-structured interviews were conducted with the respondents. Results were analyzed using NVivo 12 software.Results:Emergency patients at the end of life and their families had immediate needs, including acute symptom control, pain management, and respiratory distress treatment needs, urgent decision support needs, cultural conflict needs, immediate emotional comfort needs and alexithymia. Medical and nursing staff faced numerous obstacles when providing palliative care in emergency settings, such as role conflicts and skill gaps among emergency medical and nursing staff, lack of dedicated palliative care areas and noisy environments that hindered communication due to physical space limitations in the Emergency Department, short decision-making time and difficulties in referral due to limited emergency room time window, the multidisciplinary collaboration in the emergency department lags behind and the response of the specialized team was delayed, and lack of information sharing between emergency departments and wards.Conclusions:Emergency palliative care is characterized by both urgent needs and implementation barriers. It is necessary to optimize the physical space of the Emergency Department, establish a rapid decision mechanism for medical and nursing staff, strengthen multidisciplinary collaboration, and conduct professional training to build a palliative care model suitable for emergency situations.

Sensory modalities are important for survival but the molecular mechanisms remain challenging due to the polymodal functionality of sensory neurons. Here, we report the C. elegans outer labial lateral (OLL) sensilla sensory neurons respond to touch and cold. Mechanosensation of OLL neurons resulted in cell-autonomous mechanically-evoked Ca
