Objective:To establish and validate the diagnostic model of acute pulmonary embolism (APE) based on clinical and laboratory variables.Methods:This retrospective analysis was conducted on patients with suspected APE who underwent CT pulmonary angiography at the First Affiliated Hospital of Henan University of Chinese Medicine between February 2015 and December 2023. The patients were randomly divided into a training set and a validation set at a ratio of 7∶3. Clinical and laboratory data of the enrolled patients were collected, and patients were divided into an APE group and a non-APE group according to CT pulmonary angiography results. In the training set, univariate and multivariate logistic regression as well as Lasso regression were used to identify risk factors for APE, and a diagnostic model was developed and validated. Receiver operating characteristic curves were plotted, and calibration and decision curves were used to assess the performance of the diagnostic model. The diagnostic efficacy of the model was compared with that of the Wells score and the revised Geneva score using the DeLong test.Results:A total of 752 patients were enrolled, aged (64±15) years, including 417 (55.5%) males. The training set included 526 patients and the validation set included 226 patients. The incidence of APE in this cohort was 48.7% (366/752), with 366 cases in the APE group and 386 in the non-APE group. Multivariable logistic regression analysis showed that cyanosis ( OR=8.88, 95% CI 2.04-49.11), elevated neutrophil count ( OR=1.82, 95% CI 1.06-3.15), elevated creatine kinase isoenzyme ( OR=3.45, 95% CI 1.76-6.91), decreased partial pressure of carbon dioxide ( OR=12.88, 95% CI 7.64-22.34), elevated age-adjusted D-dimer ( OR=2.53, 95% CI 1.10-6.20), prolonged thrombin time ( OR=4.08, 95% CI 2.06-8.33), and positive lower limb venous ultrasound for thrombus ( OR=4.39, 95% CI 2.59-7.58) were risk factors associated with APE. The area under the curve ( AUC) of the diagnostic model was 0.92 (95% CI 0.90-0.94) in the training set and 0.92 (95% CI 0.89-0.95) in the validation set. The diagnostic efficacy of this model was superior to that of the Wells score ( AUC: 0.92 vs. 0.63, P<0.01) and the revised Geneva score ( AUC: 0.92 vs. 0.59, P<0.01). Conclusion:The diagnostic model for acute pulmonary embolism constructed based on clinical and laboratory parameters demonstrates excellent diagnostic performance and may facilitate rapid and accurate screening in clinical practice.

The study was conducted among 120 general practitioners (GPs) in Shanghai Fengxian District from August 2022 to March 2024, the participants were randomly divided into two age-matched groups with 60 GPs in each group. The intervention group completed a 3-month SPOC (Small Private Online Course)program, including two weeks of narrative medicine theory (concepts, questioning skills, parallel medical record writing, and professionalism) followed by monthly writing practices (three parallel records per month) and group discussions. Both groups performed routine clinical tasks, while the control group received no narrative medicine training. Baseline data were collected, Jefferson Empathy Scale scores, and Doctor-Patient Communication Skills Evaluation Scale scores were evaluated pre- and post-intervention. There were no significant differences in empathy ( P>0.05) or communication skills ( P>0.05) between two groups before the intervention. Post-intervention, both groups showed improved empathy (both P<0.05) and communication skills (both P<0.05) after intervention, while the intervention group were outperforming the control group in both measures ( P<0.05). These findings suggest that SPOC-based narrative competence training effectively enhances the empathy and doctor-patient communication abilities of general practitioners.

Objective To develop a scale suitable for assessing work stressors among intensive care unit (ICU) nurses and to examine its reliability and validity. Methods The initial questionnaire of the ICU Nurses' Work Stressors Scale was constructed through literature review, ICU nurse interviews, and Delphi expert consultation. A total of 434 ICU nurses were selected as the validation subjects using the convenient sampling method. Item analysis, exploratory factor analysis, and confirmatory factor analysis were conducted to finalize the version of the ICU Nurses' Work Stressors Scale and evaluate its reliability and validity. Results The ICU Nurses' Work Stressors Scale included six dimensions and 34 items. Exploratory factor analysis extracted six common factors with a cumulative variance contribution rate of 77.8%. The results of confirmatory factor analysis demonstrated good model fit. The scale-level content validity index of the scale was 0.965, with item-level content validity index ranging from 0.850 to 1.000. The overall Cronbach's α coefficient of the questionnaire was 0.958, and the test-retest reliability was 0.986. In a survey of 434 ICU nurses testing with the scale, the total score ranged from 22.0-160.0 (82.6±20.6) points. The scores of each dimension including nursing profession, workload, working environment, patient care, family factors and interpersonal relationship were (14.5±4.2), (21.9±5.8), (7.0±2.1), (14.1±4.2), (6.3±2.5) and (18.8±5.7) points, respectively. Conclusion ICU Nurses' Work Stressors Scale demonstrates good reliability and validity and can serve as an effective tool for evaluating work stress among ICU nurses.

ObjectiveTo observe the effect of natural moxibustion at "Feishu （BL 13）" on immune balance of T helper cell 17 （Th17） / regulatory T cell （Treg） in healthy rats. MethodsForty-eight rats were randomly divided into 10 rats in the sham moxibustion group and 38 rats in natural moxibustion group. The rats in the sham moxibustion group applied blank acupoint stickers to bilateral "Feishu （BL 13）"， and the rats in natural moxibustion group applied acupoint stickers filled with Compound Banmao Ointment （复方斑蝥膏） to bilateral "Feishu （BL 13）" for a period of 8 h. Thirty rats in natural moxibustion group were successfully blistered after 8 h， and then were randomly divided into 1-day， 3-day and 7-day groups with 10 rats in each group. The general condition of rats was recorded during the experiment； different time groups of natural moxibustion were sampled at the corresponding time， and HE staining was used to observe the pathological changes of the skin in the area of application； flow cytometry was used to detect the subpopulations of Th17 and Treg in peripheral blood， and the value of Th17/Treg was calculated； and ELISA was used to detect the serum interleukin 17A （IL-17A） and interleukin 6 （IL-6）， interleukin 10 （IL-10） levels. ResultsCompared with sham moxibustion group， blisters can be seen in the application area of rats in 1-day natural moxibustion group， and the rats often scratched the skin of the moxibustion area， which showed loose stratum corneum， thickening of the stratum spinosum and stratum granulosum， absence of cells in the basal layer， inflammatory cell infiltration， and elevation of Treg in peripheral blood， and serum IL-17A， IL-6； in 3-day natural moxibustion group， the moxibustion area of the rats was scabbed and partially detached， with the most obvious dermatopathological changes， and elevated peripheral blood Th17 and Treg， and serum IL-17A， IL-6， IL-10； in 7-day natural moxibustion group， skin damage and pathological changes in the area of moxibustion were basically restored； Th17/Treg values were reduced in 1-， 3- and 7-day moxibustion groups after blistering （P＜0.05 or P＜0.01）. Compared with the 1-day moxibustion group， peripheral blood Th17， Treg， and serum IL-17A elevated in the 3-day moxibustion group； peripheral blood Treg， serum IL-17A， and IL-6 decreased， and Th17/Treg values elevated in the 7-day moxibustion group （P＜0.05 or P＜0.01）. Compared with the 3-day moxibustion group， the 7-day moxibustion group had lower peripheral blood Th17 and Treg， serum IL-17A， IL-6， and IL-10， and higher Th17/Treg values （P＜0.05 or P＜0.01）. ConclusionNatural moxibustion at "Feishu （BL 13）" can shift the Th17/Treg balance towards Treg of healthy rats， which will gradually lead to immune homeostasis， and regulate the relevant inflammatory factors in the serum to prevent inflammation from occurring and developing.

Objective To investigate the distribution and seasonal fluctuations of visceral leishmaniasis vectors sandflies in Lüliang City, Shanxi Province, so as to provide insights into assessment of the visceral leishmaniasis transmission risk and formulation of visceral leishmaniasis control measures. Methods A total of 12 natural villages were sampled from Shilou County, Lishi District, Lanxian County, Linxian County and Wenshui County in Lüliang City, Shanxi Province from June to September, 2023, and sandflies were captured using light traps from 7 breeding habitats, including farmers’ houses, sheep pens, cattle pens, chicken coops, pig pens, mule and horse pens, and loess-cave dwellings. Following morphological identification of the sandfly species, the distribution of sandflies and the seasonal fluctuations of the sandfly density were analyzed. In addition, the Leishmania was detected in sandflies using a real-time fluorescence quantitative PCR assay. Results A total of 2 831 sandflies were captured with 156 light traps in Lüliang City from June to September, 2023, including 2 638 female sandflies (93.18%) and 193 male sandflies (6.82%), and the average density was 16.91 sandflies/(light-night). The seasonal fluctuations of the sandfly density all appeared a unimodal distribution in all survey sites, and the sandfly density peaked in July and then declined rapidly. Among all types of breeding habitats, the greatest sandfly density was found in sheep pens [39.04 sandflies/(light-night)]. In addition, 4.08% (2/49) of the sandfly samples were tested positive for Leishmania nucleic acid as revealed by the real-time fluorescence quantitative PCR assay. Conclusions Sandflies were widely distributed in Lüliang City, Shanxi Province in 2023, and the peak of the sandfly density was observed in July, which had a visceral leishmaniasis transmission risk. Intensified surveillance of visceral leishmaniasis and sandfly vectors is required and targeted vector control is recommended.

Objective:In chronic hepatitis B (CHB) patients with previous 96-week treatment with tenofovir amibufenamide (TMF) or tenofovir disoproxil fumarate (TDF), we investigated the efficacy of sequential TMF treatment from 96 to 144 weeks.Methods:Enrolled subjects who were previously assigned (2:1) to receive either 25 mg TMF or 300 mg TDF with matching placebo for 96 weeks received extended or switched TMF treatment for 48 weeks. Efficacy was evaluated based on virological, serological, biological parameters, and fibrosis staging. Statistical analysis was performed using the McNemar test, t-test, or Log-Rank test according to the data. Results:593 subjects from the initial TMF group and 287 subjects from the TDF group were included at week 144, with the proportions of HBV DNA<20 IU/ml at week 144 being 86.2% and 83.3%, respectively, and 78.1% and 73.8% in patients with baseline HBV DNA levels ≥8 log10 IU/ml. Resistance to tenofovir was not detected in both groups. For HBeAg loss and seroconversion rates, both groups showed a further increase from week 96 to 144 and the 3-year cumulative rates of HBeAg loss were about 35% in each group. However, HBsAg levels were less affected during 96 to 144 weeks. For patients switched from TDF to TMF, a substantial further increase in the alanine aminotransferase (ALT) normalization rate was observed (11.4%), along with improved FIB-4 scores.Conclusion:After 144 weeks of TMF treatment, CHB patients achieved high rates of virological, serological, and biochemical responses, as well as improved liver fibrosis outcomes. Also, switching to TMF resulted in significant benefits in ALT normalization rates (NCT03903796).
