Objective To investigate the correlation between spread through air space (STAS) of sub-centimeter non-small cell lung cancer and clinical characteristics and radiological features, constructing a nomogram risk prediction model for STAS to provide a reference for the preoperative planning of sub-centimeter non-small cell lung cancer patients. Methods The data of patients with sub-centimeter non-small cell lung cancer who underwent surgical treatment in Nanjing Drum Tower Hospital from January 2022 to October 2023 were retrospectively collected. According to the pathological diagnosis of whether the tumor was accompanied with STAS, they were divided into a STAS positive group and a STAS negative group. The clinical and radiological data of the two groups were collected for univariate logistic regression analysis, and the variables with statistical differences were included in the multivariate analysis. Finally, independent risk factors for STAS were screened out and a nomogram model was constructed. The sensitivity and specificity were calculated based on the Youden index, and area under the curve (AUC), calibration plots and decision curve analysis (DCA) were used to evaluate the performance of the model. Results A total of 112 patients were collected, which included 17 patients in the STAS positive group, consisting of 11 males and 6 females, with a mean age of (59.0±10.3) years. The STAS negative group included 95 patients, with 30 males and 65 females, and a mean age of (56.8±10.3) years. Univariate logistic regression analysis showed that male, anti-GAGE7 antibody positive, mean CT value and spiculation were associated with the occurrence of STAS (P＜0.05). Multivariate regression analysis showed that associations between STAS and male (OR=5.974, 95%CI 1.495 to 23.872), anti-GAGE7 antibody positive (OR=11.760, 95%CI 1.619 to 85.408) and mean CT value (OR=1.008, 95%CI 1.004 to 1.013) were still significant (P＜0.05), while the association between STAS and spiculation was not significant anymore (P=0.438). Based on the above three independent predictors, a nomogram model of STAS in sub-centimeter non-small cell lung cancer was constructed. The AUC value of the model was 0.890, the sensitivity was 76.5%, and the specificity was 91.6%. The calibration curve was well fitted, suggesting that the model had a good prediction efficiency for STAS. The DCA plot showed that the model had a good clinically utility. Conclusion Male, anti-GAGE7 antibody positive and mean CT value are independent predictors of STAS positivity of sub-centimeter non-small cell lung cancer, and the nomogram model established in this study has a good predictive value and provides reference for preoperative planning of patients.

Objective:To determine the erythromycin resistance of Bordetella pertussis isolates and their ptxP1 and ptxP3 phenotypic composition and compare clinical manifestations of children with pertussis caused by the two types of strains. Methods:This was a cross-sectional study, the pertussis cases diagnosed using bacterial culture from January 2019 to December 2022 in Beijing Children′s Hospital and the First People′s Hospital of Wuhu were collected.Any suspected Bordetella pertussis colonies were identified by the slide agglutination test.The susceptibility of isolates to erythromycin was detected by the E-test and K-B test.The ptxP gene was amplified by polymerase chain reaction and sequenced to determine its genotype. t-test, Mann-Whitney U-test, Chi-square test and Fisher′s exact test were use to statistical analysis. Results:A total of 192 strains of Bordetella pertussis were identified, including 188 (97.9%) erythromycin-resistant strains.Among the 188 strains, 30.3%(57/188) belonged to the ptxP1 genotype and 69.7%(131/188) belonged to the ptxP3 genotype.In children aged below 1 year old, the incidence of paroxysmal cough caused by infection with the ptxP3 strain was higher than that with the ptxP1 strain (57.1% vs.29.4%, P<0.05), and children infected with the ptxP3 strain were more likely to develop apnea or asphyxia (23.8% vs.17.6%), post-tussive vomiting (44.4% vs.32.4%), whooping cough (72.0% vs.50.0%) and pneumonia or bronchitis (85.7% vs.73.5%) compared to those infected with the ptxP1 strain, but the differences were not statistically significant(all P>0.05). In children aged 1 year old and above, the white blood cell count of children infected with the ptxP1 strain was higher than that of infections with the ptxP3 strain [13.5(9.9, 24.5)×10 9/L, 10.3 (7.0, 16.4)×10 9/L, P<0.05], and children infected with the ptxP1 strain were more likely to contract other pathogen infections than those infected with the ptxP3 strain (17.4% vs.4.4%, P>0.05). Conclusions:ptxP3 erythromycin-resistant Bordetella pertussis has become the main pathogen of pertussis.Infants with pertussis caused by the ptxP3 erythromycin-resistant strain show more significant manifestations and a higher possibility of severe symptoms than those infected with the ptxP1 erythromycin-resistant strain.

Objective To analyze the effect of neurofeedback training based on early start Denver model(ESDM)on children with autism spectrum disorder(ASD). Methods From August,2020 to May,2024,a total of 60 children with ASD from Hangzhou Children's Hospital were randomly divided into control group(n=30)and observation group(n=30).The control group received ESDM intervention,while the observation group received neurofeedback training in addition,for six months.They were assessed with Autism Treatment Evaluation Checklist(ATEC)and Psycho-Educational Profile-3rd Edition(PEP-3). Results After treatment,the score of ATEC was lower in the observation group than in the control group(t=3.545,P<0.05),the scores of cognition(t=2.236,P=0.029),emotional expression(t=2.293,P=0.025)and problem be-havior(Z=2.099,P=0.036)were higher in the observation group than in the control group.The score differenc-es of ATEC(Z=3.620,P<0.001),and cognition(Z=2.920,P<0.05)and problem behaviors(Z=4.209,P<0.05)of PEP-3 before and after intervention were higher in the observation group than in the control group. Conclusion Combination of neurofeedback training could improve the effect of ESDM on ASD.

Objective To develop a blood glucose management knowledge questionnaire for perioperative patients with hyperglycemia and test its reliability and validity.Methods The initial questionnaire was formed through literature review,expert consultation,two rounds of Delphi letter consultation,and pre-survey.From August to September 2019,a total of 125 perioperative patients with hyperglycemia who were hospitalized in the surgical ward of the First Affiliated Hospital of Xi'an Jiaotong University were selected as the survey objects by the convenient sampling method.The items of the questionnaire were screened and the reliability and validity were tested.Results A total of 125 questionnaires were distributed and 115 valid questionnaires were returned,with an effective recovery rate of 92.0%.The blood glucose management knowledge questionnaire for perioperative patients with hyperglycemia included five dimensions(17 items in total),including influencing factors and hazards of abnormal blood glucose,key points of preoperative and postoperative nursing observation,perioperative blood glucose control goals,perioperative blood glucose management points,and emergency treatment of perioperative critical conditions.The effective recovery rates for both rounds of inquiry are 100.00%,the expert authority coefficient was 0.880 and the average coefficient of variation was 0.086 and 0.065(P＜0.01).Exploratory factor analysis extracted a total of five common factors,and the cumulative variance contribution rate was 79.895%.The Cronbach's α coefficient of the questionnaire was 0.905,the test-retest reliability was 0.955,and the content validity index was 0.968.Conclusions The blood glucose management knowledge questionnaire for perioperative patients with hyperglycemia is scientific and practical,which can be used as an effective tool to evaluate the blood glucose management knowledge level during perioperative period.

Objective:To explore the quality of working life and its related factors in patients with breast canc-er returned to work after surgery.Methods:A total of 316 patients with breast cancer who had returned to work af-ter surgery were selected,and they were investigated with the General information questionnaire,Quality of Working Life Questionnaire for Cancer Survivors(QWLQ-CS),Breast Cancer Survivors Resilience Scale(BCRS)and Strat-egies Used by People to Promote Health(SUPPH).Multivariate linear regression analysis was used to analyze the related factors of quality of working life.Results:Multiple linear regression analysis showed that the QWLQ-CS score was positively correlated with education level,per capita monthly income of family,work pattern,return to work time,personal protection and social protection score of BCRS,and positive attitude scores of SUPPH(β=1.05,1.23,2.26,0.69,0.95,1.00,0.13),while negatively correlated with the complications(β=-3.83).Con-clusion:The quality of working life for patients with breast cancer after surgery needs to be improved after they re-turn to work,psychological resilience and self-efficacy are positively correlated with quality of working life.

Objective:To analyze the growth characteristics of different genotypes of Japanese encephalitis virus (JEV) in different cell lines, and to provide scientific basis for the selection of cell lines in the study of JEV.Methods:BHK-21, Vero, C6/36, PK-15, DF-1, N2a, SH-sy5y and MDCK cell lines were selected. The proliferation ability of genotype 1 (NX1889 strain), genotype 3 (P3 strain) and genotype 5 (XZ0934 strain) JEV in these cell lines was evaluated by plaque assay and RT-qPCR.Results:Significant cytopathogenic effects (CPE) were observed in BHK-21, Vero, C6/36, DF-1, N2a and PK-15 cell lines across all three JEV genotypes. However, no significant differences in CPE characteristics were observed within the same cell line. SH-sy5y and MDCK cell lines did not show significant CPE, but virus proliferation was detected in SH-sy5y cell line, while MDCK cell line were found to be insensitive to JEV. No significant difference was observed in the proliferation curves of G1, G3 and G5 JEV in BHK-21, Vero and SH-sy5y cell lines. In C6/36 and PK-15 cell lines, the titer of G1 JEV was higher than that of G3 and G5. In DF-1 cell line, G5 demonstrated a higher titer than the other two genotypes, whereas in N2a cell line, G5 showed a lower titer than the other two.Conclusions:There are differences in the proliferation of three different genotypes of JEV in different cell lines, which can provide reference for the study of JEV in different directions.

Beta-amyloid (Aβ) is considered to be a central event in Alzheimer's disease (AD). However, it has been found that some population have Aβ deposition in the brain and even AD related pathology without obvious cognitive impairment, which indicates that there are factors in the body to avoid or cope with Aβ damage, and this phenomenon is called Aβ tolerance. Starting from the concepts of resilience and reserve, this paper intends to sort out the epidemiology and quantitative methods, brain characteristics and influencing factors of Aβ tolerance, in order to further deepen clinicians' understanding of Aβ tolerance in AD diagnosis and treatment, so as to provide new ideas for prevention and treatment of the disease.

Objective:To develop the Perioperative Blood Glucose Management Knowledge Questionnaire for Surgical Nurses and test its reliability and validity.Methods:From January to June 2019, the questionnaire item pool was constructed through literature review, and 13 experts were included in two rounds of Delphi consultation using purposive sampling. In July 2019, convenience sampling was used to select 50 clinical nurses from the surgical ward of the First Affiliated Hospital of Xi'an Jiaotong University as the research subject. A preliminary survey was conducted to form an initial Perioperative Blood Glucose Management Knowledge Questionnaire for Surgical Nurses. From August to September 2019, 110 clinical nurses from this ward were selected as the research subject again, and the questionnaire was subjected to item screening and reliability and validity testing.Results:The final Perioperative Blood Glucose Management Knowledge Questionnaire for Surgical Nurses included five dimensions of factors influencing blood glucose abnormalities, hazards of blood glucose abnormalities, preoperative and postoperative nursing observation points, emergency treatment of perioperative critical conditions, and key points for perioperative blood glucose management, with a total of 19 items. In the two rounds of consultation, the positivity coefficients of experts were both 100.00% (13/13), the authority coefficient of experts was 0.88, and the coefficients of variation for two rounds of consultation were 0 to 0.30 and 0 to 0.17. Exploratory factor analysis extracted five common factors, with a cumulative variance contribution rate of 66.70%. The Cronbach's α coefficient of the total questionnaire was 0.92, the test-retest reliability coefficient was 0.97, and the scale-level content validity index was 0.98.Conclusions:The Perioperative Blood Glucose Management Knowledge Questionnaire for Surgical Nurses has good scientific and practical significance, and can be used as an effective tool to evaluate the perioperative blood glucose management knowledge among surgical nurses.

Objective:To understand the dilemma of active management in young and middle-aged postoperative patients with lumbar disc herniation, in order to provide reference for the formulation of active intervention program of self-health management meeting the needs of patients.Methods:Using the phenomenological research method, a total of 16 middle-aged and young patients with lumbar disc herniation were selected for semi-structured in-depth interviews, and the themes were analyzed and extracted by Colaizzi 7-step analysis method.Results:Three themes and nine sub-themes were extracted namely, inadequate disease response capacity and response resources (lack of disease symptom management capacity, limited access to disease management information, difficult use of disease management information, difficulty in maintaining positive self-management for a long time (forced to stop behavior change due to stress, lack of motivation to achieve good behavior change, doubts about the effectiveness of self-management) and multi-dimensional negative emotions (contrast between maintaining independence and dependence on others, fear of being misunderstood, fear of relapse) .Conclusions:Medical staff should provide comprehensive health information services for young and middle-aged postoperative patients with lumbar disc herniation, improve the out-of-hospital follow-up mechanism with the help of information technology, further improve family and social support strategies, reduce the difficulties faced in the process of active management and achieve long-term active disease management.

Objective:To investigate the application effect of the thinking pattern of "Six Thinking Hats" combined with case-based learning-reference induced self-education (CBL-RISE) teaching in clinical practice teaching of thoracic surgery.Methods:A total of 122 interns who received clinical practice teaching in Department of Thoracic Surgery in the Second Xiangya Hospital of Central South University were selected as subjects, and according to the admission order, they were divided into control group (61 interns receiving routine teaching) and observation group (61 interns receiving the thinking pattern of "Six Thinking Hats" combined with CBL-RISE teaching). After teaching, the two groups were compared in terms of assessment scores, self-learning ability, clinical thinking ability, self-expression ability, and recognition of teaching. SPSS 22.0 was used to perform the t-test and the chi-square test. Results:The observation group had significantly higher theoretical and skill assessment scores than the control group [mastery of basic knowledge: (55.42±3.65) vs. (49.57±3.23), P<0.05; case analysis: (20.13±2.19) vs. (16.42±2.74), P<0.05; medical record writing: (18.29±2.17) vs. (15.12±2.05), P<0.05; operational ability: (20.32±2.04) vs. (17.51±1.89), P<0.05; performance score: (30.34±3.24) vs. (27.19±3.07), P<0.05]. After practice teaching, both groups had increases in the scores of self-learning ability and clinical thinking ability, and the observation group had significantly higher scores than the control group [self-learning ability: (90.73±6.88) vs. (85.54±6.53), P<0.05; clinical thinking ability: (105.62±10.19) vs. (100.47±10.45), P<0.05]. Compared with the control group, the observation group had a significantly better self-expression ability ( P<0.05) and a significantly higher degree of recognition of teaching ( P<0.05). Conclusions:The thinking pattern of "Six Thinking Hats" combined with CBL-RISE teaching can improve the assessment scores of interns in thoracic surgery and stimulate their learning ability, thinking ability, and self-expression ability.
