Objective To explore the perioperative safety of video-assisted thoracic surgery (VATS) in Day Care Unit and the risk factors for delayed discharge under centralized management model. Methods The patients with VATS managed by the Day Care Unit of the Drum Tower Hospital Affiliated to Nanjing University Medical School in 2021 were retrospectively collected. The patients’ postoperative data and risk factors for delayed discharge were analyzed. Results A total of 383 patients were enrolled, including 179 males and 204 females with an average age of 46.09±14.82 years. Eleven (2.87%) patients developed grade 3-4 postoperative complications during the hospitalization. Eighteen (4.70%) patients visited unscheduled outpatient clinic within 7 days, and 6 (1.57%) patients were re-hospitalized within 30 days after discharge. The remaining patients had no significant adverse events during the 30-day follow-up. The average length of hospital stay was 2.27±0.35 d. The length of hospital stay was over 48 h in 48 (12.53%) patients. The independent risk factor for delayed discharge was lobectomy or combined resection (OR=3.015, 95%CI 1.174-7.745, P=0.022). Conclusion VATS can be safely conducted under the centralized management in Day Care Unit. The risk factor for delayed discharge is the extent of surgical resection.

Neuroplastin 65(NP65) is a glycoprotein class with selective expression in neurons. It is extensively expressed in the synaptic membrane of the central nervous system, and plays a fundamental role in cell adhesion and intercellular communication. In comparison to other cell adhesion molecules, the discovery of NP65 is relatively late and researches about this molecule are still in development. Further exploration and study of the pathophysiological mechanism involved in NP65 are needed. It has been confirmed that NP65 plays a pivotal role in neural activities, including regulation of synaptic formation and maintenance, modulation of synaptic plasticity, facilitation of neuronal development, and contribution to the pathogenesis of various diseases. Thus, NP65 could potentially serve as a crucial target for modulating the growth and operation of the nervous system. This paper provides a comprehensive review of the structure, distribution, function, and involvement in both physiological and pathological processes of NP65. Additionally, the future research direction for NP65 is proposed, with the aim of enhancing our understanding of its function, revealing its mechanism of action in diseases, and providing a theoretical basis for the development of related clinical applications.

Postoperative delirium(POD),a common surgical complication,refers to the acute and fluctuating disturbance in attention and awareness after surgery,which seriously affects the recovery and is one of the predictors of poor prognosis of patients.At present,preoperative anxiety is common in periopera-tive patients.As the independent risk factors for POD,preoperative anxiety plays an important role in the occurrence and development of POD.Taking active and reasonable intervention measures for patients with preoperative anxiety may effectively reduce the occurrence of POD.This paper reviews the effects of preoper-ative anxiety on POD,focusing on its mechanism and prevention methods,in order to explore the relation-ship between preoperative anxiety and POD,which might provide new ideas for the clinic.

Objective:To explore the nursing work items and the technical difficulty in post anesthesia care unit, so as to provide the basis for accurate calculation of anesthesia nursing workload and reasonable matching of human resources.Methods:The primary and secondary indicators of the nursing working system in post anesthesia care unit were determined through the literature review and group discussion. Delphi method was used to revise the indicators and evaluate the importance and difficulty degree of the indicators. Finally, analytic hierarchy process and linear weighted sum method were used to calculate the weight value and difficulty coefficient of each index.Results:The positive coefficients of the experts in the two rounds were 100.00%, the authority coefficients of the experts were 0.90 and 0.96, the variation coefficients ranged from 0.000 to 0.342 and 0.042 to 0.307, and the Kendall coefficients were 0.239 and 0.273 (both P<0.01). The evaluation index system of the difficulty of nursing work in post anesthesia care unit was finally composed of 10 primary indicators and 85 secondary indicators. The weight of the primary index ranged from 0.016 4 to 0.186 4, and the weight of the secondary index ranged from 0.000 8 to 0.064 3. The standardized difficulty coefficient of the secondary index ranged from 1.02 to 1.59. Conclusions:The evaluation index system of the difficulty of nursing work items in post anesthesia care unit was comprehensive and the difficulty coefficient was in line with the actual clinical work in this study, which provides reference for the follow-up scientific calculation of nursing workload and human resources matching in post anesthesia care unit.

Objective To determine risk factors of postoperative pulmonary complications within 1 month in patients undergoing thoracic surgery in Day Care Unit.Methods The total of 200 patients routinely scheduled for VATS under centralized management were enrolled in this study.On the postoperative day 1,lung ultrasound(LUS)was conducted by one physician in the ward.The patients received at least once Chest X-ray or CT in outpatient department within 30 days after discharge.The composite of out-of-hospital PPCs,and the value of LUSS in predicting the PPCs was appraised.Furthermore,we identified the perioperative risk factors associated with PPCs in VATS patients.Results Of 200 recruited VATS patients eligible in the Nanjing Drum Tower Hospital,188 participants received LUS examination and finally completed the 30 days follow-up.Of whom,68 patients developed the varied types of PPCs.Multivariable Logistic regression analysis indicated that comorbidity of immune system disease(P = 0.021),lobar resection(P = 0.031)and the postoperative 24 hours LUSS(P = 0.002)were independent risk factors for PPCs within 30 days after VATS.Conclusion Comorbidity of immune system disease,lobar resection and the postoperative 24 h LUSS were independent risk factors for PPCs within 30 days after VATS.

Chronic pain patients are often accompanied with anxiety disorder, which promote the development of each other's disease process to a certain extent and seriously affect the quality of life of patients.However, the mechanism regulating the comorbidity between the two has not been clarified.Synaptic remodeling is the alteration of synaptic structure and function, which affects the transmission of signals between neurons.Synaptic remodeling is a hot topic in the field of chronic pain and anxiety disorders, but only few studies have explored its pathological changes in chronic pain and anxiety disorders.By summarizing the relevant researches in recent years, the occurrence of chronic pain co-anxiety disorder is closely related to changes in synaptic structure, synaptic transmission efficiency and synaptic function in brain regions.Synaptic remodeling could lead to the decline of centra pain regulation ability and aggravate the progression of chronic pain accompanied by anxiety disorder through ionic amino acid receptors, neuronal transmission and interactions between neurons and glial cells.Understanding the latest research progress of the co-morbidity mechanism of chronic pain and anxiety disorder is helpful to provide theoretical basis and potential new targets for its treatment.

The incidence of emotion disability-related diseases in adolescents is increasing year by year, causing great harm to their physical and mental health, even affecting them until adulthood. However, the mechanism of this has not been fully clarified. The default mode network is a brain network composed of brain regions that are still active in the resting state. DMN is a hot pot in the field of resting state brain function research, but few studies have focused on its pathological changes in the adolescents with emotion disability-related diseases. In recent years, a number of articles related to adolescent emotion disorders have provided clues for understanding the characteristics and potential mechanisms of adolescent emotion disorders from the perspective of imaging. This paper summarized the related research over the years and found that the occurrence of emotion disorders is closely related to the activation of the default mode network brain regions, cortical thickness, gray matter volume or density, and changes in functional connections between brain areas.Some changes in brain structure and function can be used as predictive factors. In this paper, by summarizing the changes in brain imaging of these emotion disorders, we hope to explore new neuroimaging landmark changes, which can provide theoretical basis for the prevention, diagnosis and treatment of emotion disorders related diseases in adolescents.

Objective:To identify the risk factors for postoperative pulmonary complications (PPCs) in elderly patients undergoing hip surgery.Methods:The medical records of elderly patients, aged ≥ 65 yr, of American Society of Anesthesiologists (ASA) physical statusⅠ-Ⅳ, who underwent hip surgery from June 2013 to May 2019, were retrospectively collected.The patients′ sex, age, body weight, preoperative comorbidities, history of smoking and alcohol, results of the last laboratory test before surgery; mode of anesthesia, intraoperative medication, body temperature monitoring, fluid intake and output, operation time, anesthesia time; postoperative PPCs and postoperative nausea and vomiting, requirement for rescue analgesia, length of hospital stay, and perioperative blood transfusion were all collected.According to the occurrence of PPCs, patients were divided into PPCs group and non-PPCs group.Multivariable logistic regression was used to determine the risk factors for PPCs.Results:A total of 1 204 patients were finally enrolled in this study, 75 patients developed PPCs, and the incidence was 6.22%.The results of multivariate logistic regression showed that ASA physical status Ⅲ or Ⅳ, preoperative respiratory disease, postoperative transfer to intensive care unit, and perioperative blood transfusion were risk factors for PPCs, and general anesthesia combined with nerve block was a protective factor for PPCs in elderly patients undergoing hip surgery ( P<0.05). Conclusions:ASA physical status Ⅲ or Ⅳ, preoperative respiratory disease, postoperative transfer to intensive care unit, and perioperative blood transfusion are risk factors for PPCs, and general anesthesia combined with nerve block is a protective factor for PPCs in elderly patients undergoing hip surgery.

Recent advancement in natural language processing (NLP) and medical imaging empowers the wide applicability of deep learning models. These developments have increased not only data understanding, but also knowledge of state-of-the-art architectures and their real-world potentials. Medical imaging researchers have recognized the limitations of only targeting images, as well as the importance of integrating multimodal inputs into medical image analysis. The lack of comprehensive surveys of the current literature, however, impedes the progress of this domain. Existing research perspectives, as well as the architectures, tasks, datasets, and performance measures examined in the present literature, are reviewed in this work, and we also provide a brief description of possible future directions in the field, aiming to provide researchers and healthcare professionals with a detailed summary of existing academic research and to provide rational insights to facilitate future research.

Objective:To combine micro-course and flipped classroom, integrate the application of online WeChat group and teaching video, build a new teaching framework, and seek the application of flipped classroom based on "micro-course" in clinical skills training of general anesthesia and tracheal intubation for medical students.Methods:A total of 82 clinical medicine intern students of Batch 2015 and 2016 from Nnajing Drum Tower Hospital were selected as the research subjects to complete the internship (for two weeks). The teaching reform group (44 people) adopted the flipped classroom based on "micro-course"; the traditional group (38 people) adopted traditional teaching. Organized by the undergraduate teaching and research department, the number of tracheal intubation cases and the number of excellent scores were recorded during the two-week internship in anesthesia. After the rotation, a questionnaire survey was conducted to evaluate the mastery of endotracheal intubation operation and satisfaction with the teaching and training arranged by the department. SPSS 23.0 was used to conduct t test and non-parametric test. Results:The number of outstanding cases of tracheal intubation in the teaching reform group was higher than that in the traditional group, and the number of outstanding cases of tracheal intubation in girls was higher than that in boys, and the difference was statistically significant ( P<0.05). The self-assessed scores of the students' mastery of tracheal intubation and the satisfaction with clinical practice training in the teaching reform group were higher than those in the traditional group, and the difference was statistically significant ( P<0.05). Conclusion:Compared with traditional teaching, the flipped classroom based on "micro-course" has more advantages in the clinical skills training of medical tracheal intubation.
