Objective:To investigate the impact of intraoperative multimodal neurophysiological monitoring combined with blood pressure precise control on incidence of acute cerebral infarction after carotid endarterectomy.Methods:A retrospective study was peformed; 305 patients with atherosclerotic stenosis of the carotid artery admitted to and accepted carotid endarterectomy in Department of Vascular Neurosurgery, Dong'e County People's Hospital from January 2020 to September 2023 were selected. Intraoperative multimodal neurophysiological monitoring combined with traditional empirical modalities for blood pressure control was applied to 153 patients admitted to our hospital from January 2020 to December 2021 (control group), and intraoperative multimodal neurophysiological monitoring combined with blood pressure precise control (based on monitored sensory or motor wave amplitude changes) was applied to 152 patients admitted to our hospital from January 2022 to September 2023 (experimental group). Difference in postoperative acute cerebral infarction incidence between the 2 groups was compared.Results:The experimental group had significantly lower postoperative acute cerebral infarction incidence compared with the control group (4.6% vs. 13.0%, P<0.05). The experimental group had significantly lower postoperative asymptomatic acute cerebral infarction incidence compared with the control group (3.3% vs. 9.8%, P<0.05), while no significant difference was noted in postoperative symptomatic acute cerebral infarction incidence between the 2 groups ( P>0.05). Conclusion:Intraoperative multimodal neurophysiological monitoring combined with blood pressure precise control can reduce the postoperative acute cerebral infarction incidence in patients accepted carotid endarterectomy, especacailly postoperative asymptomatic acute cerebral infarction incidence, thereby enhancing surgical safety.

Objective:To analyze the status quo, hotspots and fronts of emergency nursing training research at home and abroad in the past ten years, and to provide reference and ideas for the efficient development of emergency nursing training in China.Methods:CiteSpace 6.2.R2 software was used to visually analyze the Chinese and English literatures on emergency nursing training included in CNKI and Web of Science core databases from January 1, 2013 to June 1, 2023.Results:A total of 1 177 Chinese literatures and 1 163 English literatures were included. The number of foreign articles in this field increased year by year, while the number of domestic articles showed a downward trend since 2018. There were many stable core author groups and core institution groups in foreign countries, while there was less cooperation among domestic authors and institutions. The common research hotspots and frontiers at home and abroad focused on broadening the training audience of emergency nursing, innovating the training methods of emergency nursing, strengthening the evaluation of the effect of emergency nursing training, and paying attention to the training experience and needs of nurses. Foreign researches also focused on specialized nurses, interprofessional education and nurses′mental health, etc, and the research direction was diversified.Conclusions:The development stages of emergency nursing training researches at home and abroad are different, and the research hotspots are different. In the future, we should learn from foreign research, strengthen interdisciplinary cooperation, improve the depth and breadth of research, and strengthen the cooperation between authors, institutions and countries to promote the high-quality development of emergency nursing training research in China.

Objective To investigate the safety and feasibility of transumbilical single-site laparoscopic treatment of Meckel's diverticulum in children.Methods A total of 122 patients with Meckel's diverticulum were treated with transumbilical single-site laparoscopic treatment in our department from January 2019 to June 2023.A longitudinal incision was made through the umbilical cord,and 5 mm trocars were inserted into the left and right sides of the incision.The laparoscope and non-invasive intestinal forceps were inserted via the observation and operation holes to probe the abdominal cavity and locate the diverticulum.After the umbilical cord incision was expanded,the diverticulum was pulled out from the abdominal cavity for external resection and anastomosis.Results All the 122 children were diagnosed by laparoscopy.There were 4 cases who were diagnosed as having acute gangrenous appendicitis preoperatively,but were confirmed as having Meckel's diverticulum with perforation under laparoscope intraoperatively.There were 38 cases of lower digestive tract bleeding,48 cases of inflammatory reaction,12 cases of intussusception,8 cases of intestinal obstruction caused by cord and band compression,and 12 cases of peritonitis caused by perforation.All the operations were successfully completed,and the operation time was 58-125 min,with an average of 78 min.Pathological examination after surgery showed Meckel's diverticulum in all the cases.Two cases of incision infection were cured after dressing change treatment.The patients were given a liquid diet 2-4 d after surgery and discharged 5-9 d later.A total of 119 patients were followed up for 3-18 months after surgery,and the surgical results were satisfactory.There were no serious complications such as rectal bleeding,anastomotic stenosis,adhesive intestinal obstruction,or incisional hernia after surgery.Conclusions Transumbilical single-site laparoscopic treatment of Meckel's diverticulum in children is safe and feasible.Meckel's diverticulum combined with perforation or intestinal obstruction is not a contraindication of transumbilical single-site laparoscopic surgery.

Objective To investigate the current status of ethical sensitivity among oncology nurses and explore the influencing factors in 13 Grade IIIA hospitals in Foshan to provide guidance for formulating effective intervention measures.Methods From July to September 2023,a cluster convenience sampling method was used to select 574 oncology nurses from 13 Grade IIIA hospitals in Foshan City,Guangdong Province as the research subjects.A general data questionnaire,the Chinese version of the nurse moral sensitivity questionnaire(a revised moral sensitivity questionnaire,MSQ-R-CV),the caring behaviour inventory(CBI),and the Chinese version of emotional intelligence scale(Wong and Law emotional intelligence scale,WLEIS)were used for the cross-sectional study.Univariate and multivariate linear stepwise regression were used to analyse the influencing factors.Results A total of 574 questionnaires were collected,of which 524 were valid.The total scores of ethical sensitivity,caring behaviour,and emotional intelligence of oncology nurses were(44.57±7.63),(125.86±17.95)and(86.82±14.37),respectively.Results of multivariate linear stepwise regression showed that working years in oncology departments,whether participated in medical ethics and took narrative nursing training,the total score of caring behaviour and the total score of emotional intelligence were the influencing factors of oncology nurses'ethical sensitivity(all P<0.05),jointly explained 70.5%of the total variation of ethical sensitivity(F=94.253,P<0.001).Conclusion Oncology nurses in Foshan demonstrate a medium-level of ethical sensitivity.Nurses who have≤20 years of working experience,lacking the training in medical ethics and narrative nursing within the past three years,exhibiting a shortage of caring behaviour and possessing a low emotional intelligence are more likely to exhibit low ethical sensitivity.Nursing managers should prioritise the nurses in this category with appropriate measures to enhance their ethical sensitivity.

Objective:To develop an Arteriovenous Fistula Physical Examination Knowledge, Attitude, and Practice Scale for Hemodialysis Nurses and test its reliability and validity.Methods:Based on the theory of knowledge, attitude, and practice, a preliminary scale draft was formed through a literature review, three rounds of Delphi expert consultation, and a pre-survey. Using convenience sampling, 311 hemodialysis nurses were selected for a survey from December 2022 to February 2023 for item analysis, exploratory factor analysis and reliability testing. Another survey was conducted on 260 hemodialysis nurses from February to June 2023 for confirmatory factor analysis, convergent validity, and discriminant validity testing.Results:The Arteriovenous Fistula Physical Examination Knowledge, Attitude, and Practice Scale for Hemodialysis Nurses included three subscales and five dimensions, with a total of 33 items. The content validity index at the item level was 0.867 to 1.000, and the content validity index at the scale level was 0.992. After exploratory factor analysis, two, one, and two common factors were extracted from the knowledge, attitude, and practice subscales, with cumulative variance contribution rates of 70.114%, 75.192%, and 67.467%, respectively.Confirmatory:factor analysis showed that the model fitted well. The Cronbach's α coefficients of the three subscales were 0.929 to 0.943, the half reliability coefficients were 0.861 to 0.903, and the retest reliability coefficients were 0.824 to 0.874. Conclusions The Arteriovenous Fistula Physical Examination Knowledge, Attitude, and Practice Scale for Hemodialysis Nurses has good reliability and validity and can be used to evaluate the physical examination ability of hemodialysis nurses for arteriovenous fistula.

Objective:To explore the latent classes of recurrence risk perception in ischemic stroke patients and their relationship with health behaviors.Methods:Convenience sampling was used to select 312 patients with ischemic stroke from two ClassⅢ Grade A hospitals of Guangzhou from December 2022 to June 2023 as the research subject. Before discharge, the General Information Questionnaire, Recurrence Risk Perception Scale for Patients with Stroke, and Health Behavior Scale for Stroke Patients were used for investigation. One month later, the Health Behavior Scale for Stroke Patients was used for follow-up. Latent class analysis and multiple Logistic regression analysis were used to explore the latent classes of recurrence risk perception and their influencing factors, while multiple linear regression was used to analyze the relationship between latent classes of recurrence risk perception and health behavior at 1-month follow-up.Results:A total of 312 questionnaires were distributed, and 302 valid questionnaires were collected, with an effective response rate of 96.79%. One month later, 261 study subjects completed follow-up. The recurrence risk perception in ischemic stroke patients were divided into four classes of overall low perceived accuracy, light consequence-heavy disease-moderate perceived accuracy, heavy self-care-light diet-upper moderate perceived accuracy, and overall high perceived accuracy. Age, educational level, place of residence and monthly average income were influencing factors for different latent classes ( P<0.05). Compared with patients with overall low perceived accuracy, patients with heavy self-care-light diet-upper moderate perceived accuracy, as well as those with overall high perceived accuracy, showed better health behavior after discharge, with a statistically significant difference ( P<0.05) . Conclusions:Medical and nursing staff should provide targeted nursing interventions based on the common characteristics and individual differences of different classes of patients, helping patients correctly perceive the recurrence risk, improve health behavior, and prevent stroke recurrence.

Objective To investigate the effects of granulocyte colony-stimulating factor(G-CSF)combined with tadalafil(TD)on endometrial receptivity and pregnancy outcomes in patients with thin endometrium(TE).Methods Patients with TE in the department of reproductive medicine of the First Hospital of Qinhuangdao from May 2020 to March 2023 were selected as the study subjects.They were divided into a experimental group(G-GSF combined with TD)and a control group(G-GSF)according to the different treatment regimens.The endometrial receptivity[endometrial thickness(EMT),endometrial volume(EMV),endometrial blood flow peak systolic flow rate/end diastolic flow rate(EBF-S/D),endometrial fractionation,endometrial blood flow fractionation,uterine artery pulsatility index(AUPI),uterine artery resistance index(AURI)and uterine arterial peak systolic flow rate/end diastolic flow rate(AU-S/D)]of the TE patients before and after treatment(the endometrial transition day)were compared;the endometrial receptivity on endometrial transformation day,post-treatment pregnancy outcomes[embryo implantation rate(EIR),clinical pregnancy rate(CPR),and early miscarriage rate(ABR)],and the incidence of adverse reactions during treatment were compared between the two groups.Results A total of 60 patients were included in the study,with 30 in each group.Before treatment,the difference in endometrial receptivity between the two groups was not statistically significant(P＞0.05).Compared with the pre-treatment period,the EMT,EMV,the proportion of type A endometrium and the proportion of type Ⅱ+Ⅲ endometrial blood flow significantly increased in the two groups after treatment on the endometrial transformation day increased significantly(P＜0.05),while the EBF-S/D,AUPI,AURI and AU-S/D significantly decreased(P＜0.05).EMT and EMV were greater in the experimental group than in the control group(P＜0.05),whereas EBF-S/D,AUPI,AURI and AU-S/D were less than those in the control group(P＜0.05).Compared with the control group,the differences in the proportion of endometrium,the proportion of endometrial blood flow,EIR,CPR and ABR in the experimental group were not statistically significant(P＞0.05).No adverse reactions occurred during treatment in both groups.Conclusion G-CSF combined with TD can improve endometrial receptivity in TE patients with high safety,but there is no effect on pregnancy outcome.

In order to standardize the human caring services for outpatients in medical institutions, promote the comprehensive service level of outpatient services, and improve the patient′s medical experience, Chinese Association for Life Care issued the group standard of Management Norms for Human caring of Outpatients in April 2023. This standard clarified the relevant terms and definitions of human caring for outpatients, specified the basic requirements for human caring, the humanistic quality and care responsibilities of outpatient staff, the outpatient care environment and facilities, the outpatient care process and measures, and quality management. It designed standardized and personalized full process care service norms, providing references for medical institutions at all levels to promote the development of human caring for outpatients.

Objective:To explore the values of ultrasound, pathology combined with inflammatory indicators in predicting high nodal burden (HNB) in patients with early breast cancer and to construct a nomogram to provide reference for individualized diagnosis and treatment.Methods:The ultrasonographic, pathological features and preoperative inflammatory indicators of 378 female patients diagnosed with early breast cancer confirmed by pathology in the South Hospital of the Sixth People′s Hospital Affiliated to Shanghai Jiaotong University from January 2014 to July 2022 were retrospectively analyzed. They were randomly divided into training set ( n=302) and test set ( n=76) in a ratio of 8∶2, and the baseline data of the two groups were compared. The optimal cutoff values of neutrophil to lymphocyte ratio (NLR), platelet to lymphocyte ratio (PLR) and lymphocyte to monocyte ratio (LMR) were obtained by ROC curve. In the training set, with axillary high lymph node load (≥3 metastatic lymph nodes) as the dependent variable, independent influencing factors of HNB were identified by univariate and multivariate Logistic regression analyses, and the nomogram was established. The test set data were used to verify the model. The discrimination, calibration and clinical applicability of the model were assessed by the area under the ROC curve (AUC), C-index, the calibration curve, Brier score and the decision curve analysis, respectively. Results:There were no significant differences in all variables between the training set and the test set (all P>0.05). ROC curve analysis results showed that AUCs of NLR, PLR and LMR were 0.578, 0.547 and 0.516, respectively, and the optimal cut-off values were 2.184, 150 and 3.042, respectively. Univariate Logistic regression analysis showed that age, pathological type, histological grade, Ki-67, lymphovascular invasion, NLR, PLR, ultrasonic characteristics (maximum diameter of primary tumor, shape, long/short diameter of lymph node, cortical thickness, cortical and medullary boundary, lymph node hilum, lymph node blood flow pattern) were correlated with HNB of early breast cancer (all P<0.05). Multivariate Logistic regression analysis showed that ultrasonic characteristics (maximum diameter of primary tumor >2 cm, effacement of lymph node hilum, non-lymphatic portal blood flow), lymphovascular invasion, Ki-67>14% and NLR>2.184 were independent risk factors for HNB in early breast cancer ( OR=7.258, 8.784, 6.120, 8.031, 3.394 and 3.767, respectively; all P<0.05) and were used to construct the nomogram model. The AUC of the training set was 0.914 (95% CI=0.878-0.949), C-index was 0.914; The AUC of the test set was 0.871 (95% CI=0.769-0.973), C-index was 0.871, indicating good discrimination. Calibration curve and Brier score were 0.090, indicating high calibration degree of the model. The clinical decision curve indicated good clinical benefit. Conclusions:The nomogram based on ultrasonic characteristics (maximum diameter of primary tumor, lymph node hilum, lymph node blood flow pattern), lymphovascular invasion, Ki-67 and NLR can effectively predict the risk of HNB in patients with early breast cancer, and provide a reference for precision diagnosis and treatment to avoid excessive or insufficient treatment.

Objective:To investigate the clinical features and treatment strategies of ischemic stroke during pregnancy and puerperium.Methods:This study retrospectively analyzed the clinical data of six women diagnosed with ischemic stroke during pregnancy and puerperium by cranial CT or MRI at the Second Affiliated Hospital of Shandong First Medical University from January 2013 to December 2021. Descriptive data analysis was performed.Results:There were 31 082 deliveries at the hospital in this period. The incidence of ischemic stroke during pregnancy and puerperium was 0.019% (6/31 082) during the study period. Among the six patients, three occurred in early pregnancy, one in late pregnancy, and two in the puerperium. The most common symptoms included headache, nausea, vomiting, blurred vision, convulsions, and limb movement disorders. All six patients received conservative treatment. Two term neonates were born vaginally, and one preterm infant was delivered by cesarean section. None of the three babies had any significant malformations or abnormalities in growth and development. Two pregnancies were terminated, and one received a medical abortion due to a missed abortion after embryo arrest.Conclusions:Symptoms of ischemic stroke during pregnancy and puerperium are atypical. The treatment should be individualized based on a comprehensive assessment of the etiology, severity, and maternal and fetal conditions. Maternal and fetal conditions and gestational weeks should be considered in obstetric management.
