ObjectiveTo develop a classification model based on complete blood count （CBC） parameters combined with clinical factors to predict severe respiratory infections caused by Human adenovirus （HAdV） in pediatric patients. MethodsFrom September 2023 to September 2024， the CBC parameters and related clinical data from pediatric patients diagnosed with HAdV infection were collected. Principal component analysis and random forest models were used to identify potential predictors of severe cases. ResultsA total of 668 pediatric patients were included， with 564 cases assigned to the training cohort and 104 cases to the validation cohort. Severe cases were defined as pneumonia and/or fever lasting ≥5 days （pneumonia or prolonged fever， PorPF）. Principal component analysis and feature importance analysis （Mean Decrease Gini value） identified the monocytosis ratio （PMono）， red blood cell count （RBC）， and platelet count （PLT） as the most critical CBC parameters. Logistic regression analysis revealed that oxygen therapy （OR = 4.367， 95% CI： 1.568–12.161） and increased work of breathing （OR = 3.904， 95% CI： 2.146–7.101） were relative risk factors for PorPF. Meanwhile， higher PMono （OR = 0.696， 95% CI： 0.640–0.757）， RBC （OR = 0.201， 95% CI： 0.124–0.325）， and PLT （OR = 0.990， 95% CI： 0.987–0.994） were protective factors. When PMono was used as a predictive marker for PorPF， the area under the receiver operating characteristic curve （AUC） was 0.648 and 0.705， respectively. A random forest model incorporating four risk factors ［PMono， RBC， PLT， and hematocrit （HCT）］ was constructed to classify PorPF and general cases， achieving AUCs of 0.688 and 0.768， respectively. ConclusionsPMono， RBC， and PLT may serve as characteristic CBC indicators for predicting pneumonia or prolonged fever in children with HAdV infection. A risk factor model built using PMono， RBC， PLT， and HCT offers a relatively simple and accurate approach to predicting severe cases in pediatric HAdV infections.

Objective:To investigate the depersonalization status and to analyze the effect of workplace incivility perception, intrusive rumination and fear of negative evaluation on depersonalization in clinical nurses.Methods:In May 2019, 10 cities were selected as sampling cities by the method of grabbing random ball in Henan Province and Fujian Province. Using the stratified sampling, clinical nurses were selected as the research objects for a questionnaire survey in 22 tertiary hospitals and 23 secondary hospitals, included 1200 nurses. A total of 1200 questionnaires were issued and collected, and 1159 valid questionnaires were collected with effective recovery of 96.6%. Clinical nurses were investigated by Workplace Incivility Scale, Event Related Rumination Inventory, Fear of Negative Evaluation Scale, Maslach Burnout Inventory-General Survey. The demographic characteristics of nurses' depersonalization were compared and analyzed with t test and single factor analysis of variance. The influence mechanism of workplace incivility perception, intrusive rumination and fear of negative evaluation on depersonalization was analyzed with Bootstrap. Results:Depersonalization scores were (9.3±2.6) points, 467 of those had depersonalization symptoms in clinical nurses (40.3%). The scores of depersonalization of those with <3 years of service [ (10.5±2.9) points] was higher than those with 3-10 years [ (9.1±2.8) points] and 11-31 years [ (9.0±2.9) points]. The scores of depersonalization of those with monthly earning of <3000 yuan [ (10.1±2.8) points] was higher than those with 3000-7999 yuan [ (8.4±2.7) points] and 8000-12000 yuan [ (8.0±2.9) points]. The scores of depersonalization of clinical nurses in surgical departments [ (10.0±2.9) points] was higher than those in non-surgical departments [ (8.7±2.6) points]. The scores of depersonalization of clinical nurses in tertiary hospitals [ (10.0±2.7) points] was higher than those in secondary hospitals [ (8.6±2.8) points]. The differences were statistically significant ( P<0.05). Workplace incivility perception affected depersonalization through the single mediating role of intrusive rumination, fear of negative evaluation and the chain mediating role of intrusive rumination and fear of negative evaluation ( β=0.16, 0.17, 0.07, 95% CI: 0.15-0.20, 0.15-0.21, 0.03-0.09, P<0.05) . Conclusion:Workplace incivility perception directly or through the independent mediating effects of intrusive rumination or fear of negative evaluation, and the chain mediating effects of intrusive rumination and fear of negative evaluation influences the depersonalization of clinical nurses.

Methods A totally of 1 159 clinical nurses from 10 cities in Henan Province and Fujian Province were enrolled as the research subjects using grabbing random balls method. And their status of work stress, thought suppression, difficulties in emotion regulation and emotional exhaustion were investigated by Depression-Anxiety-Stress Scale, White Bear Suppression Inventory, Brief Version of the Difficulties in Emotion Regulation Scale and Emotional Exhaustion Scale. Results The scores for work stress, thought suppression, difficulties in emotion regulation, emotional exhaustion were (23.5±3.8), (47.4±6.5), (54.1±7.2), (11.7±4.2), respectively. Among them, 40.0% of nurses experienced emotional exhaustion. Bootstrap analysis results showed that work stress positively affected emotional exhaustion among clinical nurses [standardized partial regression coefficient (β)=0.42, 95% confidence intervals (CI)： 0.36-0.44］. Work stress affected emotional exhaustion through thought suppression (β=0.16, 95%CI： 0.14-0.20), difficulties in emotion regulation (β=0.16, 95%CI： 0.14-0.19), and the chain mediating role of thought suppression and difficulties in emotion regulation (β=0.07, 95%CI： 0.04-0.09). Conclusion Emotional exhaustion symptoms are prevalent among clinical nurses. Work stress directly and indirectly influences thought suppression, difficulties in emotion regulation and emotional exhaustion of nurses.

Objective: To study the relationship between compassion fatigue and workplace psychological violence, alexithymia, and empathy in clinical nurses. Methods: A total of 1 159 clinical nurses from 10 cities in Henan and Fujian Provinces were enrolled using the method of grabbing random balls. Questionnaires including Workplace Psychologically Violent Behaviors Instrument, the Toronto Alexithymia Scale, Jefferson Scale of Empathy Health Professionals, Professional Quality of Life Scale were used to investigate the status of workplace psychological violence, alexithymia, empathy, and compassion fatigue in participants. Bootstrap analysis was used to analyze the relationship between workplace psychological violence, alexithymia, empathy, and compassion fatigue scores. Results: The average score for workplace psychological violence among clinical nurses was (26.2±6.5), with 405 nurses (34.9%) having experienced workplace psychological violence. The scores for alexithymia, empathy and compassion fatigue were (58.3±12.3), (104.3±18.6) and (48.5±6.7) respectively. Mild compassion fatigue was detected in 34.9% of participants, while moderate to severe compassion fatigue accounted for 48.8%. Bootstrap test result showed that workplace psychological violence had a positive impact on compassion fatigue ［standardized effect value (β)=0.40, 95% confidence interval(CI)： 0.35-0.44］. Workplace psychological violence had separate mediating effects through alexithymia (β=0.15, 95%CI： 0.10-0.19), empathy (β=0.16, 95%CI： 0.10-0.21) , and a chain mediating effect through alexithymia and empathy on compassion fatigue (β=0.06, 95%CI： 0.03-0.09). Conclusion: Compassion fatigue symptoms are relatively common among clinical nurses. Experiencing workplace psychological violence directly affects compassion fatigue and can indirectly affect it through the mediating effects of alexithymia and empathy.

Congenital bicuspid aortic valves(BAV)is one of the most common congenital heart diseases.It is generally diagnosed by echocardiography when deterioration of the abnormal leaflets becomes clinically evident.Patients with BAV are at increased risks of developing serious complications, including aortic stenosis, aortic regurgitation, aortic dilation, aortic dissection and/or aneurysm, which seriously threatens the health of patients.Although its diagnosis and surgical treatment have been clear, the specific pathogenesis has not been completely revealed.Recently, studies have found that gene mutations and related signaling pathway abnormalities are associated with BAV and its complications.And epigenetics and environmental factors are involved in the development and progress of BAV.Understanding the underlying cellular and molecular basis of normal and pathological aortic valve development may improve the preventative and therapeutic approaches to valve degeneration.

Objective:To investigate the effects of Danhong injection combined with intravenous recombinant tissue plasminogen activator (rt-PA) on cardiac function, myocardial zymogram and lipoprotein associated phospholipase A2 (Lp-PLA2) level in older adult patients with acute myocardial infarction (AMI). Methods:Eighty older adult patients with acute myocardial infarction who received treatment in Community-based General Hospital of Shaoxing Central Hospital, China between January 2017 and December 2019 were included in this study. They were randomly assigned to receive either intravenous thrombolysis with rt-PA (control group, n = 40) or Danhong injection combined with intravenous thrombolysis with rt-PA (observation group, n = 40). The changes in traditional Chinese medicine syndrome score, left ventricular ejection fraction, left ventricular end diastolic diameter, creatine kinase, creatine kinase-MB and lipoprotein associated phospholipase A2 level as well as adverse cardiovascular events were compared between the control and observation groups. Results:After treatment, the score of chest tightness, dark purple tongue, palpitation and shortness of breath in the two groups were decreased. After treatment, the score of chest tightness, dark purple tongue, palpitation and shortness of breath in the observation group was (2.13 ± 0.31) points, (1.98 ± 0.41) points, (1.77 ± 0.29) points, respectively, which was significantly lower than that in the control group [(2.98 ± 0.37) points, (2.52 ± 0.56) points, (2.13 ± 0.32) points, t = 11.137, 4.920, 5.272, all P < 0.001]. After treatment, left ventricular end diastolic diameter in each group was decreased compared with before treatment. After treatment, left ventricular end diastolic diameter in the observation group was significantly lower than that in the control group [(46.12 ± 4.11) mm vs. (49.74 ± 4.32) mm], and left ventricular ejection fraction in the observation group was significantly higher than that in the control group [(47.02 ± 3.55) % vs. (43.25 ± 4.10) %, t = 3.839, 4.396, both P < 0.001). After treatment, Lp-PLA2, creatine kinase, creatine kinase-MB levels in each group were decreased compared with before treatment. After treatment, Lp-PLA2, creatine kinase, creatine kinase-MB levels in the observation group were (171.02 ± 12.52) μg /L, (10.52 ± 2.11) U/L, (24.12 ± 3.52) U/L), respectively, which were significantly lower than those in the control group [(189.63 ± 11.98) μg/L, (14.71 ± 2.62) U/L, (32.79 ± 4.79) U/L), t = 6.792, 7.877, 9.224, all P < 0.001]. The incidence of adverse cardiovascular events in the observation group was significantly lower than that in the control group (5.00% vs. 22.50%, χ2 = 5.165, P < 0.05). Conclusion:Danhong injection combined with intravenous rt-PA for the treatment of acute myocardial infarction in older adult patients can greatly decrease traditional Chinese medicine syndrome score, improve cardiac function, regulate myocardial zymogram and Lp-PLA2 levels, and decrease the incidence of adverse cardiovascular events.

Objective:To explore the effect of rapamycin on 1-methyl-4-phenylpyridinium iodide (MPP+ )-induced activation of Nod-like receptor protein 3 (NLRP3) inflammasome in microglia.Methods:The BV2 microglia cells were divided into control group, model group and rapamycin group.The model group and rapamycin group were treated by MPP+ to activate NLRP3 inflammasome, and rapamycin group was pretreated with rapamycin.Quantitative real-time PCR (RT-qPCR) was used to detect the mRNA levels of NLRP3, apoptosis-associated speck-like protein (ASC) and caspase-1.Immunofluorescence was used to detect the protein expression of NLRP3 and interleukin-1β (IL-1β). Western blot was carried out to assess the protein expression of NLRP3, ASC, caspase-1, beclin1 and microtubule-associated protein 1 light chain 3 (LC3).Results:The mRNA levels of NLRP3, ASC and caspase-1 in model group were higher than those in control group ( t=4.825, 3.015, 5.853, all P<0.05). The mRNA levels of NLRP3 and caspase-1 in rapamycin group were lower than those in model group ( t=2.75, 2.89, both P<0.05). In model group, the protein expressions of NLRP3 (1.54±0.22), ASC (1.02±0.13) and caspase-1 (1.42±0.30) were higher than NLRP3 (0.66±0.15), ASC (0.41±0.14) and caspase-1 (0.70±0.10) in control group ( t=5.653, 5.602, 3.964, all P<0.01), while the protein expression of beclin1 (0.28±0.09) and LC3II/LC3I ratio(0.69±0.14) were lower than beclin1 (0.60±0.11) and LC3II/LC3I (1.29±0.23) in control group ( t=4.010, 3.982, both P<0.01). The protein expressions of NLRP3 (0.80±0.18) and ASC (0.68±0.14) in rapamycin group were lower than those in model group ( t=4.413, 3.077, both P<0.05), while the protein expression of beclin1 (0.65±0.20) and LC3II/LC3I ratio(1.42±0.36) were higher than those in model group ( t=2.965, 3.278, both P<0.05). Conclusion:MPP+ activates NLRP3 inflammasome and impairs autophagic function in microglia.Rapamycin inhibits MPP+ -induced activation of NLRP3 inflammasome by restoring autophagic impairment in microglia.
