Effects of Oxygen Pressure on the Microstructures and Nanomechanical Properties of Samarium-Doped BiFeO3 Thin Films.

In this study, samarium (Sm-10at%)-doped BiFeO3 (SmBFO) thin films were grown on platinum-coated glass substrates using pulsed laser deposition (PLD) to unveil the correlation between the microstructures and nanomechanical properties of the films. The PLD-derived SmBFO thin films were prepared under various oxygen partial pressures (PO2) of 10, 30, and 50 mTorr at a substrate temperature of 600 °C. The scanning electron microscopy analyses revealed a surface morphology consisting of densely packed grains, although the size distribution varied with the PO2. X-ray diffraction results indicate that all SmBFO thin films are textured and preferentially oriented along the (110) crystallographic orientation. The crystallite sizes of the obtained SmBFO thin films calculated from the Scherrer and (Williamson-Hall) equations increased from 20 (33) nm to 25 (52) nm with increasing PO2. In addition, the nanomechanical properties (the hardness and Young's modulus) of the SmBFO thin films were measured by using nanoindentation. The relationship between the hardness and crystalline size of SmBFO thin films appears to closely follow the Hall-Petch equation. In addition, the PO2 dependence of the film microstructure, the crystallite size, the hardness, and Young's modulus of SmBFO thin films are discussed.

Survival outcomes of east Asian patients with advanced non-small cell lung cancer treated with first-line EGFR tyrosine kinase inhibitors: A network meta-analysis of real-world evidence.

BACKGROUND: The comparative efficacies of different generation tyrosine kinase inhibitors (TKIs) in epidermal growth factor receptor (EGFR)-mutated advanced non-small cell lung cancer (NSCLC) remain largely unknown. Moreover, whether one EGFR-TKI confers superior survival remains unclear, especially in East Asians. We conducted a network meta-analysis (NMA) comparing the survival outcomes of East Asian patients with advanced NSCLC treated with first-line EGFR-TKIs. METHODS: The NMA included observational real-world evidence studies on adult patients with EGFR-mutated advanced NSCLC who received first (gefitinib and erlotinib), second (afatinib), or third (osimertinib) generation EGFR-TKIs as frontline therapy. Studies were identified through an online bibliographic search of Medline articles in the PubMed, SCOPUS, Web of Science, and Cochrane Library databases. RESULTS: For overall survival (OS), afatinib had significantly better hazard ratios (HRs) than osimertinib (HR: 0.46, 95% confidence interval [CI]: 0.23-0.91), gefitinib (HR: 0.56, 95% CI: 0.43-0.72), and erlotinib (HR: 0.71, 95% CI: 0.54-0.92). For progression-free survival (PFS), afatinib had significantly better HRs than gefitinib (HR: 0.45, 95% CI: 0.36-0.56) and erlotinib (HR: 0.63, 95% CI: 0.49-0.81). Moreover, afatinib was most likely to achieve the longest OS (81.3%), followed by erlotinib (13%), osimertinib, and gefitinib. Furthermore, afatinib was most likely to achieve the longest PFS (48.3%), followed by osimertinib (34.9%) and erlotinib. CONCLUSIONS: This real-world evidence shows that afatinib confers better survival than other first-line EGFR-TKIs in East Asian patients with advanced NSCLC.

Do patient characteristics affect EGFR tyrosine kinase inhibitor treatment outcomes? A network meta-analysis of real-world survival outcomes of East Asian patients with advanced non-small cell lung cancer treated with first-line EGFR-TKIs.

BACKGROUND: Despite the well-established efficacies of tyrosine kinase inhibitors (TKIs) in epidermal growth factor receptor (EGFR)-mutated non-small cell lung cancer (NSCLC), there is limited real-world evidence comparing their effectiveness according to patients' clinical characteristics. This network meta-analysis (NMA) compared survival outcomes among first-line EGFR-TKIs in different subgroups of East Asian patients with advanced NSCLC. METHODS: This NMA included real-world observational studies reporting outcomes with TKIs in patients aged >65 years, with baseline brain metastasis, with different Eastern Cooperative Oncology Group (ECOG) statuses, or with different common EGFR mutation types. RESULTS: In patients with the EGFR L858R mutation, afatinib resulted in significantly longer progression-free survival (PFS) than erlotinib (hazard ratio [HR]: 0.59, 95% confidence interval [CI]: 0.46-0.75) and gefitinib (HR: 0.41, 95% CI: 0.32-0.53). Similarly, in patients with the EGFR Del19 mutation, afatinib and erlotinib resulted in significantly longer PFS than gefitinib (HR: 0.48 with 95% CI: 0.33-0.71 and HR: 0.54 with 95% CI: 0.36-0.80, respectively). Moreover, afatinib resulted in significantly longer PFS than gefitinib in patients with brain metastasis (HR: 0.53, 95% CI: 0.33-0.87) or ECOG status 0-1 (HR: 0.37, 95% CI: 0.23-0.59). CONCLUSION: This NMA suggests that afatinib results in similar PFS to erlotinib and superior PFS than gefitinib in patients with Del19 mutant NSCLC, aged ≥65 years, with ECOG scores of 0-1, and with baseline brain metastasis.

T790M detection rate after first-line combination therapy with bevacizumab and EGFR-TKIs in advanced NSCLC (TERRA Study).

Real-world data regarding the T790M mutation rate after acquiring resistance to first-line combination therapy with epidermal growth factor receptor-tyrosine kinase inhibitors (EGFR-TKIs) and bevacizumab in patients with advanced non-small-cell lung cancer (NSCLC) are limited. The present study was aimed at analyzing predictors of acquired T790M mutations in this patient group. A total of 107 patients who received first-line combination therapy with EGFR-TKIs and bevacizumab at 11 tertiary referral centers in Taiwan were enrolled in this multicenter retrospective study. Survival data and genomic test results after acquiring resistance were analyzed. We discovered that patients who received a combination of afatinib, a second generation EGFR-TKI, and bevacizumab showed better progression-free survival (PFS). After disease progression, 59 patients (55.1%) were confirmed to test positive for EGFR T790M. A longer duration of first-line therapy could be a predictor of subsequent T790M mutations. To our knowledge, this is one of the few and early studies to demonstrate the T790M mutation rate after first-line combination therapy with an EGFR-TKI and bevacizumab. Whether the longer PFS afforded by the addition of bevacizumab could lead to subsequent T790M mutations needs further investigation.

The effect of trauma advanced practice nurse programme at a Level I regional trauma centre in mainland China.

AIMS: Trauma is the fifth-leading cause of death in China. Despite the establishment of the Chinese Regional Trauma Care System (CRTCS) in 2016, advanced trauma nurse practice has not been incorporated. This study aimed to identify the roles and responsibilities of trauma advanced practice nurse (APN), and to investigate the impact on patient outcomes in a Level I regional trauma centre in mainland China. DESIGN: A single-centre pre- and post-control design was used. METHODS: The trauma APN programme was established based on multidisciplinary experts' consultation. A retrospective study was conducted on all Level I trauma patients over a period of 5 years, spanning from January 2017 to December 2021, with a sample size of 2420. The data were divided into two comparison groups: a pre-APN programme (January 2017-December 2018; n = 1112) and post-APN programme (January 2020-December 2021; n = 1308). A comparison analysis was conducted to evaluate the effectiveness of trauma APN who were integrated into the trauma care team, with a focus on patient outcomes and time-efficiency indicators. RESULTS: The certification of the regional Level I trauma centre resulted in a 17.63% increase in the number of trauma patients. The integration of advanced practice nurses (APN) into the trauma care system led to significant improvements in time-efficiency indicators, with the exception of advanced airway establishment time (p < 0.05). The average emergency department length of stay (LOS) decreased 21%, from 168 to 132 min (p < 0.001); additionally, the mean intensive care unit LOS decreased by nearly 1 day (p = 0.028). Trauma patients who were treated by trauma APN had a higher likelihood of survival, with an odds ratio of 1.816 (95%CI: 1.041, 3.167; p = 0.033), compared to patients who received care prior to the implementation of the trauma APN program. CONCLUSION: A trauma APN programme has the potential to enhance the quality of trauma care in the CRTCS. IMPACT: This study elucidates the roles and responsibilities of trauma advanced practice nurses (APN) in a Level I regional trauma centre in mainland China. Trauma care quality was significantly improved after the application of a trauma APN programme. In regions with inadequate medical resources, the utilization of advanced practice trauma nurses can enhance the quality of trauma care. In addition, trauma APN can provide a trauma nursing education programme within the regional centres as a strategy to augment the proficiency of regional trauma nursing. No patient or public contribution, the research data all from trauma data bank.

Therapists' practical implementation and preparation of online counseling in the post-pandemic era.

In recent years, COVID-19 has led to a blossoming of online counseling (OC) as an important and alternative way to help people in need. In this regard, the present study aims to explore and clarify therapists' practical implementation and preparation of OC in the post-pandemic era by developing scales. In total, 306 Taiwanese licensed therapists participated in this study and filled out the developed scales (75 males and 231 females, 246 of whom have provided OC to clients). The psychometric analysis revealed that the two scales developed in this study, the implementation of OC scale and the preparation of OC scale, have positive reliability and validity. The former consists of three factors: standardized process, presence of infrastructure, and similarity in practice, and the latter comprises two factors: intent to conduct OC and perceived benefits for clients. In addition, the results indicated that therapists who are elder, more experienced, or working in community mental health facilities showed better practical implementation and preparation of OC. Findings from this study carry useful reference for strengthening therapists' preparation for and the effectiveness of OC.

Exploration of the thinking and methods in treatment of cancer pain with acupuncture and moxibustion on the base of the fascia theory / 中国针灸

There is a commonality between jingjin (muscle region of meridian) and the fascial network for coordinating the balance in the body. The occurrence and the progression of tumor may disrupt the overall coordination between the fascial network and jingjin directly or indirectly, thereby, the impairment of this coordination may result in cancer pain. Rooted on the theory of overall balance of the fascial network, and combined with understanding of pain in jingjin theory, professor HUANG Jin-chang emphasizes the importance of "relaxing the knot" in treatment of cancer pain. It is recommended to select the fascia reaction point as the target point, in accordance with the principle of balance adjustment and apply various acupuncture and moxibustion therapies, such as Fu's subcutaneous needling, small-needle scalpel therapy, fire needling, and moxibustion.

The Mechanism Study of Moxa Combustion Products on Regulating Vascular Endothelial Function in Atherosclerotic Mice.

Objective: To evaluate the anti-atherogenic effect of moxa combustion products (MCPs) and whether it is mediated through improving the vascular endothelial function in ApoE-/- mice. Methods: A total of 60 male ApoE-/- mice were randomly divided into the moxa smoke (MS) group, filtered moxa smoke (FMS) group, moxa floss volatile (MFV) group, essential oil of Artemisia argyi (EOAA) group, and model group (n = 12/group), while 12 male C57BL/6 mice were used as the control group. The six groups were intervened for 20 min/day, 6 days/week. After 14 weeks of intervention, the mice were euthanized and their blood lipids were measured. The aortic roots and thoracic aortas were collected for haematoxylin and eosin (HE) or Oil Red O staining, respectively. The contents of AMPK, PI3K, Akt, and eNOS mRNA in the thoracic aortas were examined by RT-qPCR. Results: The MS group and FMS group showed significantly lower plaque area percentage in the aortic roots and thoracic aortas and higher contents of AMPK-mRNA and eNOS-mRNA in the thoracic aortas compared with the model group. Conclusion: MS and FMS equally suppressed the progression of atherosclerotic lesions in ApoE-/- mice. It was suggested that the particulate matter in MS may not be the key components of moxibustion.

Association of baseline parameters with year 0 and year 1 acute exacerbations in male patients with chronic obstructive pulmonary disease.

OBJECTIVES: Acute exacerbations (AEs) of chronic obstructive pulmonary disease (COPD) can affect health status, hospitalization and readmission rates, and disease progression. This study aimed to identify independent markers associated with COPD AEs. METHODS: This study included male patients with COPD and collected data regarding their AEs and baseline clinical parameters. RESULTS: We included 149 male patients. Among them, 58 were included in the year 0 high-AE group and 91 in the low-AE group. Multivariate analysis revealed that the high-AE group had higher white blood cell count, lower serum albumin level, and post-bronchodilator (BD) forced expiratory volume in one second (FEV1) (%) with a combined receiver operating characteristic curve (ROC) of 0.721 (p < 0.001). Additionally, 34 patients were included in the year 1 high-AE group and 70 in the low-AE group (p < 0.001). Multivariate analysis revealed that the high-AE group had higher platelet count, positive asthma history, and lower pre-BD FEV1 (%) with a combined ROC of 0.782 (p < 0.001). CONCLUSION: In male patients with COPD, baseline white blood cell count, albumin level, and post-BD FEV1 (%) were correlated with year 0 AE; on the other hand, baseline platelet count, positive asthma history, and pre-BD FEV1 (%) were associated with year 1 AE.

The Survival of Septic Patients with Compensated Liver Cirrhosis Is Not Inferior to That of Septic Patients without Liver Cirrhosis: A Propensity Score Matching Analysis.

Background: We aimed to determine whether septic patients with liver cirrhosis (LC) had worse survival than septic patients without liver cirrhosis (WLC). We also investigated the survival of septic patients with compensated liver cirrhosis (CLC) and decompensated liver cirrhosis (DLC). Methods: This study enrolled 776 consecutive adult patients with sepsis admitted to the medical intensive care units of a tertiary referral hospital. Clinical factors and laboratory data were collected for analysis. Propensity scoring was also used for the control of selection bias. The variables included in the propensity model were age, sex, presence of diabetes mellitus, hypertension, cardiovascular accident, chronic kidney disease, malignancy, APCHE II (Acute Physiology and Chronic Health Evaluation) score, hemoglobin, and platelet data on the day when sepsis was confirmed. Seven-day, ICU, and hospital mortality were analyzed after correcting for these confounding factors. Results: Of the 776 septic patients, 64 (8.2%) septic patients presented with LC. Patients were divided into two groups­LC (n = 64) and WLC (n = 712)­which presented different rates of hospital mortality (LC: 62.5% vs. WLC: 41.0%, p = 0.001). We further separated septic patients with LC into two groups: patients with CLC (n = 24) and those with DLC (n = 40). After propensity score matching, the survival of septic patients with CLC (63.6%) was not inferior to patients WLC (54.5%) (p = 0.411). Patients with DLC had more hospital mortality, even after matching (p < 0.05). The Quick SOFA (qSOFA) score, SOFA score, and sub-SOFA score were also comparable between groups. SOFA scores were not significantly different between the CLC and WLC groups after matching. Poor SOFA scores were observed in the DLC group on days 3 and 7 after matching (p < 0.05). Conclusions: Septic patients with LC had higher mortality compared to patients WLC before matching. However, after propensity score matching, the survival of septic patients with CLC was non-inferior to patients WLC.

Zeaxanthin Attenuates the Vicious Circle Between Endoplasmic Reticulum Stress and Tau Phosphorylation: Involvement of GSK-3ß Activation.

BACKGROUND: Alzheimer's disease (AD) characterized by neurofibrillary tangles caused by hyperphosphorylated tau is the most common cause of dementia. Zeaxanthin (Zea), derived from fruits and vegetables, may reduce the risk of AD. Endoplasmic reticulum stress (ERS) might cause memory impairment in AD. OBJECTIVE: Here, we studied protective role of Zea on the relationship among ERS, activity of glycogen synthase kinase 3ß (GSK-3ß, tau phosphorylated kinase), and p-Tau (Ser 396 and Thr 231). METHODS: The results were obtained in non-RA and RA group by using different treatment, such as 9-cis-retinoic acid (RA), TM (ERS inducer), Zea, 4-PBA (ERS inhibitor), and SB216763 (GSK-3ß inhibitor). The methods included flow cytometry and MTT [3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide] for the detections of cell cycle and cell viability and western blot as a third measure of proteins in relation to ERS and tau phosphorylation. We have collected and analyzed all the data that suggested application of drugs for the treatment in non-RA and RA group. RESULTS: Zea displays its protection on TM-induced cell injury, upregulation of GRP78 expression, and change of GSK-3ß activity and tau phosphorylation when 4-PBA and SB216763 interfere with the process. CONCLUSION: These studies indicated that Zea is in vicious circle in ERS, GSK-3ß, and tau phosphorylation, and further reflect its potential value in AD.

Changes in voice quality, swallowing, and pulmonary function after parathyroidectomy for secondary hyperparathyroidism.

OBJECTIVE: To find changes in voice quality, airway invasion during swallowing, pharyngeal residue after swallowing, acoustic and aerodynamic measurements and pulmonary function tests after total parathyroidectomy plus auto-transplantation for secondary hyperparathyroidism. METHODS: We recruited 38 patients who underwent successful surgery for secondary hyperparathyroidism in this study. Voice quality was evaluated using voice handicap index (VHI-10), eating assessment tool (EAT-10), voice impairment, and the grade, roughness, breathiness, asthenia, strain (GRBAS) scale. Acoustic and aerodynamic measurements included fundamental frequency (F0), maximal phonation time, high pitch, jitter, s/z, shimmer and noise-to-harmonic ratio. Vocal cord mobility, vocal cord closure, premature spillage, the penetration-aspiration scale and the Yale pharyngeal residue severity rating scale (PRSRS) after swallowing were examined using fiber-optic endoscopy. Pulmonary function tests included forced vital capacity, forced expiratory volume in 1 s, bronchodilator test, total lung capacity, diffusion capacity of the lung for carbon monoxide, alveolar volume, and distance and O2 desaturation of the 6 min walking test (6MWT). RESULTS: Four months after successful parathyroidectomy, VHI-10 improved significantly (p < 0.01); incomplete vocal cord closure decreased significantly (p < 0.01); the Yale PRSRS for vallecula and pyriform sinus improved significantly (p = 0.02 and p = 0.02); F0 and high pitch increased significantly (p < 0.01 and p = 0.01); O2 desaturation (<4%) of 6MWT improved significantly (p = 0.04). CONCLUSIONS: Parathyroidectomy for secondary hyperparathyroidism can improve the voice quality, vocal cord closure, the Yale PRSRS for vallecular and pyriform sinus and O2 desaturation of 6MWT, and increase F0 and high pitch.

Dynamic monitoring of kidney injury status over 3 days in the intensive care unit as a sepsis phenotype associated with hospital mortality and hyperinflammation.

BACKGROUND: Sepsis-associated acute kidney injury (AKI) often worsens with the deterioration of a patient's condition. Therefore, we hypothesized that monitoring AKI dynamically from day 1 to day 3 was potential to predict hospital mortality. Specifically, we explored whether monitoring AKI dynamically in the intensive care unit (ICU) could be a sepsis phenotype predictive of mortality. A new classification was established based on the change in the AKI stage from admission day 1 and day 3. We compared the hospital mortality, cytokines, and immune response pattern between each group. METHODS: We retrospectively enrolled 523 patients with sepsis, and we calculated the AKI stages on day 1 and day 3 admission to ICUs. Among these 523 people, 388 of them were assigned to normal, improved, and deteriorated groups according to the changes in the AKI stages. 263 of which did not develop AKI on day 1 and day 3 (normal group). The AKI stage improved in 68 patients (improved group) and worsened in 57 (deteriorated group). We compared the mortality rates between the groups, and identified the relationship between the dynamic AKI status, immune response patterns, and cytokine levels. RESULTS: The hospital mortality rate in the deteriorated group was higher than that in the non-deteriorated group (combination of normal and improved group) (p = 0.004). Additionally, according to the Kaplan-Meier analysis, the non-deteriorated group had a distinct hospital survival curve (p = 0.004). Furthermore, both the overexpression of tumor necrosis factor-α and decreased monocyte expression of human leukocyte antigen-DR were present in the deteriorated group. CONCLUSIONS: The deteriorated group was associated with a higher hospital mortality rate, potentially resulting from an abnormal inflammatory response. Worsening AKI in the first 3 days of ICU admission may be a sepsis phenotype predictive of hospital mortality.

Comprehensive analysis of PD-L1 in non-small cell lung cancer with emphasis on survival benefit, impact of driver mutation and histological types, and archival tissue.

BACKGROUND: The aim of the study was to assess programmed death-ligand-1 (PD-L1) expression in different histological types and gene mutation status of patients with non-small cell lung cancer (NSCLC). METHODS: A total of 4062 pathology-confirmed lung cancer patients were retrospectively screened at Kaohsiung Chang Gung Memorial Hospital from November 2010 to June 2017. There were 699 NSCLC patients with confirmed PD-L1 expression level retrospectively enrolled for analysis. RESULTS: There was a trend of higher PD-L1 expression in squamous cell carcinoma and adenosquamous cell carcinoma than in adenocarcinoma (p = 063). Significant higher PD-L1 expression in EGFR wild-type was noted (p < 0.001). No significant differences in PD-L1 expression were found between ALK wild- and mutant types, but there seem was a trend of high PD-L1 level noted in ALK mutation patients (p = 0.069). In EGFR mutation patients, a higher time to treatment failure (TTF) duration was observed in no PD-L1 expression (p = 0.011). Longer tumor tissue storage time correlated with lower PD-L1 expression in lung cancer (p < 0.001 for linear trend). CONCLUSIONS: There were a trend or significant differences in PD-L1 expression between different histological types in NSCLC, different EGFR and ALK status, and different tumor tissue storage time. A higher survival benefit was observed in no PD-L1 expression than with PD-L1 expression in adenocarcinoma, EGFR and ALK mutation patients. We recommend that PD-L1 assay should be performed as early as possible if tissue is available.

Research status and trends of acupuncture and moxibustion for cancer：a bibliometric analysis based on CiteSpace and VOSviewer / 中国针灸

To analyze the research status of acupuncture and moxibustion for cancer at home and abroad in the past 45 years by using bibliometric and scientific knowledge map methods，and explore the development trends in future. The literature of acupuncture and moxibustion for cancer was retrieved from CNKI and Web of Science (WOS) till December 31, 2020 since the database establishment, and CiteSpace and VOSviewer software were used to perform visual map analysis through cooperation network, keyword co-occurrence, keyword timeline, keyword emergence and other methods. Totally, 1 585 literature in CNKI and 1 564 literature in WOS were included, and the annual publication amount showed a fluctuating upward trend. Cooperation between countries was centered on China and the United States, and there was relatively little cooperation among different institutions. The analysis of keyword and cited literature showed that researches focused on the control of acupuncture and moxibustion therapy on cancer complications and adverse reactions of western medicine. The main research types in WOS were systematic review and randomized controlled trial (RCT), while in CNKI was review, depth studies on mechanism of acupuncture and moxibustion for cancer were rare. The concern about the quality of life of cancer patients may become research emphasis in the field of acupuncture and moxibustion for cancer in future, and the research scope tends to integrative and holistic oncology.

Comparative analysis of CT imaging findings on pulmonary alveolar proteinosis and pneumoconiosis / 中国职业医学

@#Objective To analyze the difference in computed tomography (CT) imaging findings between pulmonary alveolar pneumoconiosis Methods proteinosis (PAP) and occupational pneumoconiosis (hereinafter referred to as ). A total of 44 patients with PAP (PAP group) and 44 patients with pneumoconiosis (pneumoconiosis group) were selected as study subjects using Results convenient sampling method. The CT images of these two groups were comparatively analyzed. The detection rates of - - pulmonary CT pattern changes such as map like performance, ground glass opacity, paving stone sign and sphenoid wing like vs vs changes of pulmonary hilum in the PAP group were higher than those in the pneumoconiosis group (77.3% 0.0%, 75.0% vs vs P 2.3%, 56.8% 0.0%, 18.2% 0.0%, all <0.01); the detection rates of lymphadenopathy and calcification of pulmonary hilum, small pulmonary nodules, emphysema and interlobular septal thickening were lower in the PAP group than those in the vs vs vs vs P Conclusion pneumoconiosis group (34.1% 100.0%, 4.5% 100.0%, 2.3% 45.4%, 0.0% 22.7%, all <0.01). Paving - stone sign and map like performance were most commonly found in the CT imaging of patients with PAP, and it is uncommon in pneumoconiosis. These changes could be used as the CT differential diagnosis of the two diseases.

Association of maternal adverse childhood experiences and parenting styles with emotional behavior problems in preschool children / 中国学校卫生

Objective@#To explore the role of parenting style in the association of maternal adverse childhood experiences (ACEs) and emotional behavior problems (EBPs) in preschool children, so as to provide a reference for the prevention and control of EBPs in children.@*Methods@#A total of 6 111 children aged 3-6 years old from 36 kindergartens in 3 areas of Anhui Province in June 2021, follow up data were collected in December 2021. Maternal ACEs, mother child relationship and children EBPs were respectively assessed using the Adverse Childhood Experiences International Questionnaire(ACEs-IQ), Parental Rearing Style Scale and the difficulty score factor in the Chinese Strength and Difficulty Questionnaire(SDQ). The Bootstrap was used to examine the mediation effect of maternal parenting styles.@*Results@#Maternal ACEs were positively associated with child SDQ difficulty scores( r = 0.28, P <0.01). Negative parenting (indulgent, permissive, authoritarian and inconsistent) were positively correlated with maternal ACEs scores( r =0.28, 0.30, 0.21, 0.31) and child SDQ difficulty scores( r =0.25, 0.20, 0.20, 0.28)( P <0.01). Positive parenting (democracy) was negatively correlated with maternal ACEs and SDQ difficulty scores( r =-0.09, -0.29, P <0.01). After adjusting for confounding factors, the results of the mediation effect test of Bootstraping procedure showed that maternal parenting styles (indulgent, democracy, permissive, authoritarian and inconsistent) played a mediation role in maternal ACEs and EBPs of preschool children, and the mediation effects were respectively 19.13%, 7.34%, 24.88%, 12.05% and 26.83%.@*Conclusion@#Parenting styles play a mediating role in the association of maternal ACEs and EBPs in preschool children, and improving mothers negative parenting styles is of great significance to reduce EBPs in the offspring of maternal ACEs.

Comparisons of Anti-dsDNA Antibody Detection Methods by Chemiluminescent Immunoassay and Enzyme-Linked Immunosorbent Assay in Systemic Lupus Erythematosus.

This study aimed to compare the test results of anti-double-stranded DNA (anti-dsDNA) antibodies obtained using chemiluminescent immunoassay (CIA) and enzyme-linked immunosorbent assay (ELISA), and investigate predictors of inconsistent results. This retrospective study included 502 patients who underwent CIA and ELISA to determine their anti-dsDNA antibody values within a year. We compared the diagnostic power for SLE, disease activity, and predictive power for lupus nephritis (LN). A multivariate analysis was performed to determine the predictors of inconsistencies. CIA and ELISA were moderately correlated in terms of their consistency (Cronbach's α = 0.571), and yielded comparably favorable results in terms of SLE diagnostic power and SLE disease activity. However, if the patient had LN, CIA displayed higher predictive power than ELISA (0.620 vs. 0.555, p = 0.026). Compared with the CIA/ELISA double-positive group, the inconsistent group had lower anti-C1q circulating immune complexes (CIC) antibody values (OR: 0.42, 95% CI: 0.18-0.94, p = 0.036), and lower SLEDAI scores (≥4) (OR: 0.33, 95% CI: 0.14-0.79, p = 0.013). Anti-dsDNA antibody detection with CIA exhibited higher predictability for diagnosing LN than did ELISA. In the event of inconsistencies between anti-dsDNA methods, SLE disease activity and CIC test values should be considered simultaneously.
