Objective:To evaluate the reliability and validity of the Chinese version of Consultation and Relational Empathy (CARE) Measure in the Mandarin speaking population.Methods:From March to June 2018, patient interviews and expert consultations were conducted to explore problems of CARE in Mandarin context and preliminary revisions were made to the measure, then the final adapted tool was developed. A questionnaire survey on the validity of the measure was conducted from July to August 2018, among 373 patients from three community health service centers in Beijing Chaoyang District, selected by convenience sampling. The questionnaire included general information of participants and the revised CARE measure. The results of the survey were analyzed for the reliability and validity of Chinese version of CARE measure.Results:In the culture adaptation stage, 30 word-changes and 13 phrase-changes were made to improve the cultural adaptation of CARE. A total of 373 valid questionnaires were were collected with a valid recovery rate of 100.0%. The participants had a mean age of (60.8±13.12) years, with females of 68.6% (256/373), junior high school or high school education of 58.7% (219/373), and retirees of 71.3% (266/373). The results showed that there was a significant difference in scores of each item between the high group (top 27%) and the low group (bottom 27%) ( P<0.001). There was a positive correlation between each item and the total score, with a correlation coefficient between 0.817 and 0.868 ( P<0.001). The reliability analysis results show that the Cronbach′s α of the revised CARE was 0.960. In the content validity analysis, among the 10 items, the proportion of patients who considered the item "not applicable" was between 1.1% and 4.8%, and the proportion who considered the item "important" was between 92.8% and 96.2%. In exploratory factor analysis, KMO=0.944 and Bartlett′s sphericity test P<0.001. One common factor with an eigenvalue>1 was extracted, and the cumulative variance explained by which was 73.85%, with the load value of each item of 0.815-0.909. Conclusion:The revised Chinese version of CARE measure shows good reliability and validity and it can be applied in primary care settings for Mandarin speaking population.

The study was a prospective observational study. A total of 24 patients who underwent maintenance hemodialysis (MHD) at Haidian Hospital in Beijing from May 2024 to June 2024 were included as the study subjects. The safety and efficacy of a new single-needle dialysis in MHD patients were evaluated. The reasons for using single-needle dialysis included waiting for the maturity of internal fistula(7 cases, 29.17%), autogenous arteriovenous fistula thrombosis occurred (6 cases, 25.00%), puncture difficulty occurred (7 cases, 29.17%), and pain sensitivity or elderly (4 cases, 16.67%). The results showed that the average blood flow was (155.65±5.90) ml/min, total blood volume was (35.92±2.65) L during single-needle dialysis. One patient had slight puncture leakage, and the puncture success rate was 95.83%. Relevant indicators of dialysis adequacy showed that the average urea clearance (Kt/V) was 0.90±0.42, urea reduction ratio was 58.31%±7.93%, and online real-time Kt/V monitoring average value was 0.98±0.55. The results suggest that the application of the new improved single-needle dialysis mode in MHD patients is safe and effective.

Objective:To explore the cut-off value of metastatic lymph node ratio (LNR) for stage N3 gastric cancer and construct a new TNM staging system to predict prognosis.Methods:Clinical data of 4 291 patients from Jan 2004 to Dec 2020 in the SEER database and 567 patients from Jan 2016 to Dec 2020 in the First Affiliated Hospital of Zhengzhou University with stage N3 gastric cancer were collected. A new TNrM staging system and a nomogram model were constructed based on the optimal LNR cut-off value and compared with the 8th TNM staging model in terms of prognostic discrimination, prognostic prediction accuracy, and clinical usefulness.Results:The optimal cut-off value of LNR was 0.5. A TNrM staging system was constructed by combining the Nr stage with the T stage. Univariate and multivariate COX regression analyses showed that the TNrM staging system was a significant prognostic factor (all P<0.05). Based on the 8th TNM and TNrM staging system, two nomograms were constructed in the training set and externally validated in the validation set. Compared with the TNM staging model, the TNrM staging model had a larger C-index and area of time-dependent ROC curve(AUC) (training set: 3-year AUC: 66.5 vs. 74.4, 5-year AUC: 68.9 vs. 75.3; validation set: 3-year AUC: 62.3 vs. 73.1, 5-year AUC: 62.6 vs. 75.8), its overall survival prediction curves were closer to the ideal curve in the calibration curve, and its clinical net benefit was greater in the decision curves. Conclusions:Stage N3 gastric cancer patients with a metastatic lymph node ratio >0.5 have a poor prognosis. The TNrM staging nomogram model constructed based on the lymph node ratio has better prognostic discrimination ability and prediction accuracy and more clinical net benefits compared to the 8th edition of TNM staging nomogram model.

Objective:This study aimed to evaluate the effects of hypertensive disorders of pregnancy (HDP), including their clinical subtypes, on neonatal heel blood methionine levels and explore potential dose-effect relationships.Methods:A retrospective cohort study was conducted among 11 007 singleton pregnancies and their neonates delivered at Beijing Obstetrics and Gynecology Hospital, Capital Medical University, from July 2021 to October 2022. Participants were stratified into an HDP group [ n=992; 480 with gestational hypertension, 512 with preeclampsia (including 229 severe cases)] and a non-HDP control group ( n=10 015). Methionine concentrations were measured using tandem mass spectrometry from heel blood dried filter paper samples collected within 72 hours post-delivery. Statistical analyses included non-parametric tests to compare intergroup differences, multiple linear regression to evaluate the effects of HDP on methionine levels, and multivariate logistic regression to identify risk factors for hypermethioninemia (>50 μmol/L). Results:(1) Baseline data: Maternal age was higher in the HDP group compared to controls [33 (30-36) vs. 33 (30-35) years, Z=－2.29, P=0.022], with elevated pre-pregnancy body mass index (BMI) [23 (21-26) vs. 21 (20-23) kg/m2, Z=－17.15, P<0.001] and increased gestational hyperglycemia prevalence [26.5% (263/992) vs. 19.8% (1 986/10 015), χ2=27.95, P<0.001]. (2) Methionine level: Neonates in the HDP group exhibited higher methionine levels [25.96 (21.58-30.89) vs. 24.77 (20.45-29.53) μmol/L, Z=－5.26, P<0.001], with a severity-dependent gradient: gestational hypertension [25.83 (21.77-30.61)], preeclampsia [26.05 (21.23-31.11)], and severe preeclampsia [26.15 (21.25-32.13)] ( Z=2.97, 3.92, 2.26; all P<0.05). Trend analysis confirmed a dose-effect relationship between HDP and neonatal methionine ( χ2=7.82, P=0.005). (3) Multivariate analysis: After adjusting for confounding factors such as maternal age and BMI, HDP remained independently associated with elevated methionine levels ( β=0.93, 95% CI: 0.47-1.40, t=3.92, P<0.001) and increased hypermethioninemia risk ( OR=2.75, 95% CI: 1.13-6.68). Subgroup analysis revealed ORs of 3.20 (95% CI: 1.07-9.57) for gestational hypertension, 3.25 (95% CI: 1.09-9.72) for preeclampsia, and 5.23 (95% CI: 1.54-17.82) for severe preeclampsia (all P<0.05). (4) Neonatal outcomes: Neonates in the HDP group had lower birth weights [3 230 (2 910-3 560) vs. 3 335 (3 070-3 600) g, Z=－7.43, P<0.001] and higher fetal growth restriction rates [10.3% (102/992) vs. 3.1% (306/10 015), χ2=136.47, P<0.001]. Conclusions:HDP demonstrates an elevation of neonatal methionine levels, correlating with disease severity, particularly in severe preeclampsia. These findings underscore the necessity for enhanced metabolic monitoring and long-term follow-up in offspring of mothers with HDP, especially those with severe preeclampsia.
