Humanistic caring for patients in the operating room refers to providing the whole process of caring medical services for patients in the operating room. In order to standardize humanistic caring services for patients in the operating room of medical institutions, improve the comprehensive service level of the operating room, and enhance the surgical experience of patients, the Chinese Association for Life Care released the group standard " Humanistic Caring Management Standards for Patients in the Operating Room" in December 2023. This article interpreted the basic requirements for humanistic caring of patients in the operating room, the environment and facilities for humanistic caring, the procedures and measures for humanistic caring, and the quality management framework, aiming to assist administrators and clinical practitioners across various levels of medical institutions in accurately understanding and effectively implementing the standard, and to provide essential textual reference and practical guidance for promoting the application of the standard.

Objective To explore the current situation and influencing factors of post-intensive care syndrome(PICS)in critically ill patients a month after their transfer out,and to provide a basis for formulating individualized intervention measures.Methods By the convenience sampling method,550 patients who were transferred out of the ICU of a tertiary A hospital in Guizhou Province for a month from April to November 2024 were selected as the survey subjects.The general information of the patients was collected and sorted out.During their stay in the ICU,the Barthel Index,the Richards Campbell Sleep Scale,and the Perceived Social Support Scale were employed for evaluation.A month after the patients were transferred out of the ICU,the assessment was completed through telephone follow-up using the Chinese version of the Brain Care Monitoring Questionnaire for Healthy Aging.According to the assessment a month after the patients were transferred out,they were divided into a PICS group and a non-PICS group.Univariate analysis and binary Logistic regression analysis were completed based on the data of the 2 groups.Results A total of 550 questionnaires were distributed,and 442 valid questionnaires were ultimately collected,with a valid questionnaire collection rate of 80.3％.Among them,194 cases(43.9％)were high-risk patients with PICS.Binary logistic regression analysis showed that advanced age,pulmonary infection,total hospitalization time＞15 days,and internal environment disorder were the risk factors for PICS in ICU patients(P＜0.05).Conclusion The risk of PICS is relatively high in critically ill patients a month after the transfer.Medical staff need to pay attention to patients who are older,have pulmonary infections and internal environment disorders,and formulate personalized intervention measures for different disease types to improve the long-term health prognosis of patients.

Objective To investigate the feasibility,efficacy and safety of cold snare polypectomy(CSP)and endoscopic mucosal resection(EMR)in treatment of colonic adenoma in proximity to the orifice of appendix.Methods Clinical data of 41 cases of colonic adenoma in the orifice of appendix treated with CSP(CSP group)and 15 cases treated with EMR(EMR group)from January 2018 to January 2023 were collected.The clinicopathological features and outcomes were analyzed.The main outcome was postoperative complications,including bleeding,perforation and postoperative appendicitis,while the secondary outcome was the total resection rate,block resection rate and local recurrence rate.Results The operation time and treatment cost of CSP group were shorter than EMR group,and the differences were statistically significant(P<0.05).The diameter of applicable lesions in CSP group was smaller than that in EMR group,and the proportion of lesions with tubular adenoma was significantly higher than that in EMR group.There were no significant differences in the time of admission,intestinal preparation score,length of stay,lesion morphology and lesion type between the two groups(P>0.05).Perforation and postoperative appendicitis were not observed in both groups,and delayed postoperative hemorrhage occurred in 1 case in the CSP group,but it could heal itself after surgery without endoscopic intervention.The complete resection rate was 100.0%in both groups.The total removal rate of CSP group was 100.0%,which was significantly higher than that of EMR group(86.7%),and the difference was statistically significant(P<0.05).The local recurrence rate was 2.4%(1/41)in CSP group,and no local recurrence was observed in EMR group(0/15),with no statistical significance(P>0.05).Conclusion CSP and EMR are safe and effective in the treatment of colonic adenoma in proximity to the orifice of appendix,and they are trustworthy.Compared with EMR,CSP is more applied to small diameter tubular adenomas,which has the characteristics of economy and time saving,but at the same time there is the risk of recurrence.EMR obviously has a wider application range,but there is a disadvantage in price and time,and individual cases need to be segmented resection.

Sneddon syndrome is a rare neurocutaneous disorder that primarily affects small-and medium-sized arteries.Its clinical manifestations include livedo racemosa and recurrent cerebral ischemic events,and it may also involve multiple organs such as the heart,spleen,and kidneys.This disease can lead to early-onset stroke,making it a rare cause of stroke in young adults.This article reported a case of a young female patient who experienced two cerebral infarctions within one month.Genetic testing identified a homozygous mutation in the adenosine deaminase 2 gene,confirming the diagnosis of Sneddon syndrome.This case serves as a reference to improve clinical recognition of this disease.

Objective This study aims to investigate the application of Lean Six Sigma(LSS)management in the con-text of the"live streaming+science popularization"in development of national regional medical centers.Methods Utilizing the five stages of definition,measurement,analysis,improvement,and control in the LSS management method,this paper analyzed the management difficulties in the application of the"live broadcast+science popularization"integration model under the back-ground of national regional medical center development.Brainstorming,root cause analysis,and other methods were used to ana-lyze the key links that affected the"live broadcast+science popularization"model,proposed solutions,and established a stand-ardized operation mechanism,compared the changes in cumulative views,likes,and interactive messages of"live streaming+science popularization"before and after implementation.Changes in awareness and satisfaction of health education among resi-dents within the jurisdiction,as well as chronic disease readmission rates,were evaluated.Results Following the implementa-tion of LSS management,there was a significant increase in cumulative views,likes,and interactive comments associated with science popularization live broadcasts.Additionally,the awareness of health education and satisfaction with health science dis-semination among residents significantly improved.Furthermore,the readmission rates for chronic disease patients across the hos-pital exhibited a statistically significant decrease(P＜0.05).Conclusion LSS management can effectively improve the quality of the"live streaming+science popularization"integration model,enhance the health literacy of residents in the jurisdiction,and reduce the readmission rate of chronic disease patients.

Objective:To compare and analyze the parameters of image quality of virtual mono-energetic images(VMIs)and conventional computed tomography(CT)images of dual-energy CT(DECT)imaging for the coracoclavicular ligament,and to optimize the image quality of DECT imaging for coracoclavicular ligament.Methods:The DECT image data of shoulder joints of 50 patients who received DECT scan in the First People's Hospital Affiliated to Shanghai Jiao Tong University were retrospectively analyzed.450 VMIs at energy levels of 40 to 120 keV were obtained through the Syngo.via VB20 workstation,and these VMIs were divided into three groups:low energy level(40,50,60 keV),medium energy level(70,80,90 keV),and high energy level(100,110,120 keV).The contrast-to-noise ratio(CNR),the direction of coracoclavicular ligament's rows,and the displayed subjective quality scores of attachment points of VMIs were compared with those of conventional CT images.The results of MRI examination were used as the"gold standard"to assess the effectiveness of VMIs in diagnosing coracoclavicular ligament injuries of patients with acromioclavicular joint dislocation.The diagnostic efficacies of VMIs'the three groups and conventional images were assessed by using receiver operating characteristic(ROC)curve.Results:The CNR values of diagonal ligament and conical ligament at 40 keV of low energy level group of VMIs for coracoclavicular ligament were respectively 14.09±3.27 and 13.9±3.06,and those of medium energy level group were respectively 11.89±4.01 and 12.17±4.08,and those of high energy level were respectively 9.69±4.25 and 9.78±4.33.The CNR value of low energy level group was significantly higher than that of medium and high energy level groups,and the differences were statistically significant(t=21.1,16.3,P<0.05),respectively.The results of ROC curve analysis indicated that the sensitivity,specificity and area under curve(AUC)value of the low energy level group were relatively higher in diagnosing coracoclavicular ligament injury,which were respectively 90.05%,91.95%and 0.965.There was high consistence in assessing coracoclavicular ligament injury between DECT's VMIs and MRI examination(Kappa=0.896).Conclusion:DECT's VMIs can better display the rows and attachment points of diagonal ligament and conical ligament,and the VMIs quality at low energy level(40 to 70 keV)is the best,which has better diagnostic efficacy in diagnosing coracoclavicular ligament injury.

Objective:To explore the latent categories of nurses' perception of high-performance work systems (HPWS) through latent profile analysis and analyze the differences in characteristics and influencing factors among different categories.Methods:A convenience sampling method was used to select 3 450 clinical nurses from ClassⅡ、Ⅲ hospitals in 12 regions of China between June and July 2024. General information questionnaires, the Perceived High-Performance Work System Scale, and the Nurse Voice Behavior Scale were used for data collection. Latent profile analysis was conducted to analyze nurses' perception of HPWS, and multi-class logistic regression was used to examine the influencing factors for different categories.Results:A total of 3 450 questionnaires were collected, with 3 385 valid responses, yielding an effective response rate of 98.12%. Nurses' perception of HPWS had an average score of (70.46±12.21), which could be divided into three latent categories: low perception (17%, 559/3 385), moderate perception (42%, 1 433/3 385), and high perception (41%, 1 393/3 385). The multi-class logistic regression analysis showed that job nature, title, position, years of service, monthly income, health impact on work, work duration, and monthly night shifts were significant factors influencing nurses' perception of HPWS ( P<0.05) . Conclusions:There is heterogeneity in the nurses' perception of HPWS. Nursing managers should focus on nurses with low perception of HPWS and provide interventions and support based on the characteristics and influencing factors of each category to improve nurses' voice behaviors.
