In this study, we proposed an idea on systematic construction and optimization of a clinical coaching teacher qualification access system in Peking University Third Hospital by combining lean thinking and the Six Sigma methodology and following the steps of definition, measurement, analysis, improvement, and control. Based on the constructivism theory, the clinical coaching teacher qualification access system is divided into two progressive sessions: access to clinical coaching qualifications and access to theoretical teaching qualifications. By analyzing the appraisal data of clinical coaching teacher qualification access in the past 10 years, we revealed the data characteristics of pass rates of clinical coaching qualifications to determine the goal for dynamic improvement. On top of this analysis, we identified measures to maintain a stable pass rate of clinical coaching teacher qualification access, optimized the development direction and path of the clinical coaching teacher qualification access, and continuously promoted the teaching ability of teachers through the coordinated implementation of different systems and measures. In our research, we expanded the administrative scope of the access system, sorted out the objectives and paths of the system improvement, and provided a practical reference for constructing a clinical coaching teacher qualification access system and promoting the construction of teaching quality standardization in university-affiliated hospitals.

Malignant hyperthermia(MH)is a rare perioperative disease with autosomal dominant inheritance,and its pathogenesis involves specific gene mutations.Its clinical feature is that conventional anesthetics can trigger abnormally high metabolic reactions in skeletal muscles.Although the incidence of this disease is low,the condition is dangerous,progresses rapidly,and has a high mortality rate;Its treatment relies on early diagnosis,timely application of the specific drug Dantrolene Sodium,and rapid and orderly comprehensive symptomatic supportive treatment.MH is a critical perioperative emergency that can occur during surgery.It presents with symptoms such as hyperpyrexia,metabolic acidosis,rhabdomyolysis,and dysfunction of multiple organ systems.If not treated promptly,it can quickly lead to life-threatening arrhythmias and cardiac arrest.This condition serves as an essential teaching example in anesthesia crisis resource management.As an effective teaching method,scenario simulation exercises can comprehensively enhance medical staff's personal technical,non-technical,and teamwork abilities through simulating emergency scenarios,teaching assessments,and retrospective discussions,especially suitable for comprehensive management training of fatal diseases.Many countries internationally have incorporated simulation exercises for MH into their routine teaching and training systems.The effectiveness of teaching and training for anesthesiologists in MH and their ability to handle anesthesia crisis events have been continuously improved through a periodic training model.This article systematically reviews the research progress and practical experience of scenario simulation exercises in emergency training for MH,with a focus on exploring how to establish a scenario simulation exercise plan for emergency application and comprehensive symptomatic support treatment of Dantrolene Sodium based on the actual situation in China,providing reference for improving the teaching and training quality of MH and other clinical crisis events.

Piezo1 is a mechanosensitive ion channel protein widely expressed in mammalian cells with the function of sensing mechanical stimuli and of mediating signaling,and is embedded in the membranes of erythrocytes,the major cellular component of blood.Piezo1 regulates the morphology and function of erythrocytes by mediating the in-flux of Ca2+into the cell in crosstalk with the Gardos channel(KCa3.1),constituting the"Piezo1-Ca2+-Gardos channel axis".However,when Piezo1 is abnormally expressed or over-activated by its specific agonist(Yoda1),it can also lead to abnormal erythrocyte morphology and dysfunction,and even cause the development of related he-reditary diseases.

The prevention and treatment of adolescent depression and suicide represent a current focal point. Therefore, it is crucial to understand the risk factors for suicide in adolescents with depression, scientifically monitor suicide risk, and conduct a multidisciplinary collaboration. There is still a lack of authoritative, evidence-based guidelines in China on how to assess suicide risk early time and how to take targeted prevention. This paper introduces the bio-psycho-social joint intervention model, aiming to help clinicians comprehensively assess the suicide risk in adolescents with depression. The author discussed comprehensive assessment methods and a collaborative system involving family, school, medical, and community entities working together as more effective interventions.

The damage caused by space microgravity environment to the body systems of astronauts directly affects their work efficiency.This paper reviewed previous studies on the effects of space microgravity environment and ground simulated microgravity environment on cognition and emotion, potential mechanisms and interventions. It was found that a microgravity environment led to dysfunction in learning, memory, spatial orientation and other aspects, and caused anxiety and depression. The mechanisms of cognitive and emotional impairment associated with microgravity environment are complex, including neuronal damage, brain structure changes, neurotransmitter disorders, synaptic dysfunction, oxidative stress injury, and energy metabolism disorders. Pharmacological approaches such as natural extracts, physical interventions such as repetitive transcranial magnetic stimulation, and new therapies such as probiotics were expected to reduce cognitive impairment and mood disorders caused by microgravity exposure. With the development of aerospace medicine in China, the potential mechanism and interventions of microgravity environment on cognitive and emotional impairment remain to be further studied.

Objective:To evaluate the development of hypothermia after spinal anesthesia and risk factors.Methods:Patients undergoing spinal anesthesia in the anesthesia preparation room of our hospital from April 2020 to April 2021 were included. The temperature of the tympanic membrane was measured before spinal anesthesia and immediately after anesthesia and at 5, 10 and 15 min after anesthesia. Patients with tympanic membrane temperature<36 ℃ at any time point were considered as having hypothermia and included in hypothermia group and patients with membrane temperature ≥ 36 ℃ were considered as having no hypothermia and included in non-hypothermia group. The patients′ demographic data, highest anesthesia plane, puncture space of spinal anesthesia, types of anesthetics, preoperative fasting time, and surgical sites were recorded. The multivariate logistic regression analysis was performed to identify the risk factors for hypothermia.Results:A total of 196 patients were finally enrolled. The body temperature was significantly decreased at 5 and 10 min after anesthesia compared with the baseline body temperature before anesthesia and immediately after anesthesia ( P<0.001), and the incidence of hypothermia was 10.2%. The multivariate logistic regression analysis showed that female and high anesthesia plane were independent risk factors for hypothermia, and higher baseline body temperature was an independent protective factor for hypothermia ( P<0.05). Conclusions:Body temperature decreases at 5-10 min after spinal anesthesia, and the occurrence of hypothermia is not a small probability event in the patients undergoing spinal anesthesia; female and higher anesthesia plane are risk factors and higher baseline body temperature is the protective factor.

Objective:To investigate and analyze the awareness of malignant hyperthermia (MH) in anesthesiology nurses in mainland China.Methods:From November 2021 to January 2022, anesthesiology nurses of secondary hospitals or above in Chinese mainland were enrolled by convenience sampling and investigated by a self-designed questionnaire on the awareness of MH.The system automatically recorded the situation of questionnaires.Results:A total of 2 058 anesthesiology nurses participated in the survey, distributed in 21 provinces, 2 autonomous regions (Ningxia Hui Autonomous Region, Guangxi Zhuang Autonomous Region) and 4 municipalities directly under the central government, and 2 049 questionnaires were effectively received with effective recovery of 99.56%.The correct answers to questions related to the treatment of MH, characteristics of the disease, classification, susceptible population, screening method of the susceptible population, genetic mode, inducing factors, the first symptoms and the best infusion time of dantrolene, preparation method of domestic dantrolene and the first dose were 86.58%, 82.33%, 58.18%, 50.90%, 50.76%, 50.42%, 45.73%, 32.89%, 51.25%, 48.32% and 46.51%, respectively.Only 27.13% of anesthesiology nurses expressed that dantrolene was available in their hospital.The scores of knowledge about MH among anesthesiology nurses in hospitals of province-level municipalities and provincial capital cities were significantly higher than those in other cities ( P<0.001). The scores of knowledge about MH among the anesthesiology nurses in secondary hospitals were significantly higher than those in tertiary hospitals ( P<0.05). There was no significant difference in the scores of knowledge about MH among anesthesiology nurses with different professional titles, educational backgrounds, and working years ( P>0.05). Conclusions:Anesthesiology nurses in mainland China have insufficient awareness of MH.Popularizing the knowledge about MH and strengthening the awareness of MH in medical staff in the department of anesthesiology throughout the country may be of great significance in improving the diagnosis and treatment of MH in China.
