Objective: To conduct network analysis of biased constitution to provide theoretical basis for daily health management. Methods: Purposive sampling and snowball sampling methods were used to collect the required data via a web-based questionnaire from February 3rd, 2022 to January 21st, 2023. The tendency scores of 8 biased constitutions (qi-deficiency type, yang-deficiency type, yin-deficiency type, phlegm-dampness type, damp-heat type, blood-stasis type, qi-depression type, and special diathesis type) were evaluated by 30-Item Short Version of Constitution in Chinese Medicine Questionnaire. Data analysis was conducted in R. The qgraph package was used to construct network analysis models and calculate the edge weight, namely regularised partial correlation coefficients (r) and centrality coefficients (including strength, closeness, betweenness and expected influence), while mgm was used to calculate the predictability of each node within the network. The ggplot2 package was used to visualize network analysis result, and bootnet was applied to assess the structural reliability and robustness of the network, including the r accuracy assessment, the stability assessment of the centrality coefficients, and the difference test result of node centrality coefficients. Results: A total of 3, 691 valid samples were obtained from the survey. The result of the network analysis showed that: (1) the strength of the association between phlegm dampness type and damp-heat type (r=0.370), qi-deficiency type and qi-depression type (r =0.315), qi-deficiency type and special diathesis type (r=0.260), qi-deficiency type and phlegm-dampness type (r=0.247), and the phlegm-dampness type and qi-depression type (r=0.247) was high. (2) The centrality of phlegm-dampness type and qi-deficiency type was the strongest, and the differences between the centrality coefficients of phlegm-dampness type and qi-deficiency type were not significant. There were no other nodes where all 4 centrality coefficients were not significantly different from qi-deficiency type and phlegm-dampness type, and the predictability of phlegm-dampness type and qi-deficiency type was the highest. (3)The result of the r accuracy assessment showed that the r of this network did not differ significantly from the average of multiple samples, so the r accuracy of this network was high. (4) Correlation stability(CS) coefficient of the four centrality indicators were CS Strength=0.59, CS Closeness=0.75, CS Betweenness=0.75, and CS Expected influence=0.75. This indicated that the stability of the centrality indicators of this network was very good. Conclusion Complex connections exist between various biased constitutions, and phlegm-dampness type and qi-deficiency type are the two key biased constitutions in the entire biased constitution.

Objective:To investigate the status of sedentary behavior and its influencing factors among inpatients with stable schizophrenia, providing empirical evidence for developing interventions to reduce sedentary behavior.Methods:A cross-sectional survey design was used to prospectively collect clinical data from 166 inpatients with stable schizophrenia (97 males, 69 females, mean age 56.4±8.4 years) hospitalized at the Shanghai Mental Health Center affiliated with Shanghai Jiao Tong University School of Medicine from February 2024 to May 2024. Sedentary behavior time was assessed using the Sedentary Behavior Questionnaire (SBQ), daily step count was measured via pedometers, and negative schizophrenic symptoms were evaluated using the Scale for the Assessment of Negative Symptoms (SANS). Patients were divided into a non-sedentary behavior group (≥5 000 steps/day, 66 cases) and a sedentary behavior group (<5 000 steps/day, 100 cases). Clinical variables were compared between the two groups, and binary logistic regression was used to identify influencing factors of sedentary behavior.Results:Stable inpatients with schizophrenia exhibited high levels of sedentary behavior, with an average daily sedentary time of (8.03±2.33) hours and a median daily step count of 3 352 (1 258-5 506) steps. Significant differences were observed between sedentary and non-sedentary behavior groups in Age ( t=-2.38),hospitalization duration ( Z=-1.53),blunted affect ( t=-8.37),poverty of thought ( t=-2.45),avolition ( t=-2.45),impoverished interests/social engagement ( t=-2.41),abdominal obesity ( χ2=9.18),and open vs. restricted hospital/wards environment ( χ2=8.88)(all P<0.05). Binary logistic regression analysis identified that hospital/wards environment ( OR=0.314, 95 %CI: 0.125-0.787),hospitalization duration ( OR=1.001, 95 %CI: 1.000-1.001),and the negative symptom of blunted affect ( OR=3.256, 95 %CI: 1.960-5.407)(all P<0.05) were significantly influencing factors for sedentary behavior in patients with stable schizophrenia. Conclusion:Hospitalized patients with stable schizophrenia exhibit high levels of sedentary behavior. Hospital/wards environment and blunted affect are significant factors influencing sedentary behavior.

Objective To evaluate the application value of aspiration catheter and debulking technology in the treatment of patients with intermediate-and high-risk pulmonary thromboembolism(PTE).Methods The clinical data of 28 patients with intermediate-and high-risk PTE were analyzed retrospectively.All subjects received thrombectomy using a 7F JR Guiding catheter.The success rate of surgery and the incidence of complications were counted,and the preoperative and postoperative values in heart rate(HR),systolic blood pressure(SBP),oxygen saturation(SO2),partial pressure of oxygen(PO2),Miller index,and mean pulmonary arterial pressure(MPAP)were compared.Results All patients were successfully treated,of which 26 cases obtained symptomatic relief after surgery.There were 2 cases of death in high-risk patients,of whom one died of myocardial infarction,and the other died of cerebral herniation after the procedure.One case reported the formation of pulmonary artery small dissection which disappeared within 2 months during conservative observation.The postoperative HR,Miller index,and MPAP decreased and SBP,SO2,and P()2 increased significantly than those of preoperative(P＜0.05).The follow-up period for this group ranged from 7 to 29 months,with a median follow-up of 14.6(7,19)months.During the follow-up period,no recurrences were observed.Conclusion The aspiration catheter and debulking technology demonstrate efficacy in treating intermediate-and high-risk PTE,and is associated with favourable success rates and low complication rates.The findings suggest its potential for wider clinical use.

Objective:To analyze the current situation of health-related quality of life (HRQOL) and its influencing factors among community-dwelling elderly with mild cognitive impairment (MCI) based on the health ecology model (HEM).Methods:From December 2023 to September 2024, a cross-sectional survey was conducted among 997 community-dwelling elderly in Beijing, Shandong, Chongqing and other regions. The EuroQol five-dimensional questionnaire 5 level (EQ-5D-5L), the Montreal cognitive assessment (MoCA), and the Pittsburgh sleep quality index (PSQI) were used to assess the subjects.Descriptive analysis, Mann-Whitney U test, Kruskal-Wallis test, and Tobit regression analysis were performed using Stata 18.0 software. Results:A total of 324 valid samples were finally obtained, and the health utility value of MCI elderly was 0.842(0.815, 0.951). Tobit regression analysis showed that ≥80 years old( β=-0.121, 95% CI=-0.193--0.050) in individual traits level, don't exercise( β=-0.196, 95% CI=-0.255--0.137) and poor quality of sleep ( β=-0.064, 95% CI=-0.116--0.013) in behavior characteristics level, and poor subjective economic status( β=-0.153, 95% CI=-0.261--0.045) in living and working conditions level were risk factors for the health utility value of the elderly with MCI. Drinking( β=0.096, 95% CI=0.022-0.171) in behavior characteristics level and participating in social activities( β=0.126, 95% CI=0.062-0.190) in interpersonal network level were protective factors for the health utility value of the elderly with MCI. Conclusions:The HRQOL of the community-dwelling elderly with MCI in China is low, and its influencing factors are multi-level. HEM should be combined to strengthen the intervention and management of the elderly with MCI from personal constitution to policy environment to improve their HRQOL.

Objective:To explore the application effect of debate-style ethics teaching among undergraduate nursing interns under the background of "doctor-patient conflicts".Method:A total of 128 nursing interns,who interned in Yantai Affiliated Hospital of Binzhou Medical University from January 2022 to July 2023,were selected as the research subjects.Using the historical controlled study and according to the random envelope method,undergraduate nursing interns from June 2022 to December 2022 were divided into the intervention group with a total of 64 cases,and undergraduate nursing interns from January 2023 to July 2023 were divided into the control group with a total of 64 cases.Finally,60 undergraduate nursing interns both the intervention group and the control group completed this study.The control group adopted the traditional nursing ethics teaching mode,while the intervention group adopted debate-style ethics teaching based on the background of "doctor-patient conflicts".The teaching effect was evaluated by using the Ethical Sensitivity Questionnaire for Nursing Students,the Professional Identity Questionnaire for Nursing Students,and the Clinical Nursing Instructors before and after the intervention.Result:The research results showed that the scores of ethical sensitivity,professional identity,and clinical nursing instructors of nursing interns in the intervention group were higher than those in the control group after the intervention,and the differences were statistically significant (P<0.05).Conclusion:Debate-style ethics teaching based on the background of "doctor-patient conflicts" can improve the ethical sensitivity,professional identity,and clinical nursing instructors of nursing interns,as well as significantly improve the effectiveness of clinical nursing ethics mentoring.

ObjectiveTo explore the longitudinal measurement invariance of standardized Constitution in Chinese Medicine Questionnaire （CCMQ） among Chinese adult populations， and to provide evidence for the longitudinal effect analysis of this questionnaire. MethodsA total of 509 adults who voluntarily received 26 weeks of comprehensive traditional Chinese medicine （TCM） constitution fitness intervention were included （3 time points： before intervention， 13 weeks intervention， and 26 weeks intervention）， evaluated by CCMQ with 9 subscales. A single-group confirmatory factor analysis was performed to establish a single-group baseline model with a well-fitting model， and then nested models， that is multiple groups of confirmatory factors analysis， are used to analyze the longitudinal measurement invariance， followed by configural invariance， metric invariance， scalar invariance， and strict invariance. Comparative Fit Index （CFI）， Root Mean Square Error of Approximation （RMSEA）， and Standardized Root Mean Square Residual （SRMR） were used as model fit indicators for the analysis. ResultsThe single-group confirmatory factors analysis proved that the 9 subscales of CCMQ fit well at the three time points （CFI： 0.933~0.992， RMSEA： 0.027~0.080， SRMR： 0.022~0.045）. The multiple-group confirmatory factors analysis showed that the configural， metric， scalar， and strict invariance across time of qi-stagnation and special diathesis constitution were established （ΔCFI＜0.01， ΔRMSEA＜0.01）； the configural， metric， scalar， and partial strict invariance across time of phlegm-dampness constitution subscale were established （ΔCFI＜0.01， ΔRMSEA＜0.01）； the configural， metric， partial scalar and partial strict invariance of 6 subscales， including gentleness， qi-deficiency， yang-deficiency， yin-deficiency， dampness-heat， and blood-stasis constitutions， were all established （ΔCFI＜0.01， ΔRMSEA＜0.01）. ConclusionThe CCMQ met at least metric invariance at 3 time points， which can be applied to the study of whether different time points have the same unit or meaning. The measurement invariance of the 3 subscales of phlegm-dampness， qi-stagnation and special diathesis， special diathesis have longitudinal measurement invariance， so the mean comparison over time could be made； while the 6 subscales of gentleness， qi-deficiency， yang-deficiency， yin-deficiency， dampness-heat， and blood-stasis constitutions meet partial scalar and partial strict invariance， which could be explained partially for the difference in the comparison of the mean over time.

The paper summarizes the imaging evaluation methods for assessing the degree of carotid artery stenosis and analyzes the unique advantages and limitations of various imaging techniques in vascular imaging based on existing guidelines and consensus.The paper focuses on reviewing the clinical applications of several novel ultrasound technologies,including the use of advanced hemodynamic parameters such as blood flow dispersion(Tur index)and wall shear stress(WSS).Carotid artery stenosis is closely associated with cardiovascular disease.Although non-invasive and radiation-free ultrasound technology has certain limitations in diagnostic accuracy to a certain extent,with the continuous emergence of advanced functions such as ultrasound hemodynamics and vascular elasticity,the combination of multi-modality and multi-parameter ultrasound is expected to become an important method for efficient diagnosis of arterial stenosis in the future.
