RÉSUMÉ

OBJECTIVE: The purpose of this study is to construct an organ system-centered undergraduate nursing professional training model and explore its application effect. METHODS: This study is divided into two steps. In the early stage, literature review and expert consultation were used to establish the training mode (curriculum and assessment standard) of nursing undergraduate specialty based on organ system reform. Secondly, a cross-sectional survey method was used to investigate the training quality of nursing students who graduated from Jinzhou Medical University from 2007 to 2017 under this model. RESULTS: A five-module curriculum system was established, including general courses, public basic courses, professional education courses, expanding elective courses and concentrated practical teaching. Under the teaching reform of organ system, the nursing graduates of Jinzhou Medical University, who are mainly employed in public hospitals, are generally not satisfied with their jobs, salaries, contents and prospects. Their overall satisfaction with their alma mater is very high; Graduates have certain independent core competence; Employers are basically satisfied with graduates. CONCLUSION: The training mode of undergraduate nursing specialty based on organ system reform basically meets the training requirements and objectives.

RÉSUMÉ

Climate change severely affects crop production. Cotton is one of the primary fiber crops in the world and its production is susceptible to various environmental stresses, especially drought and salinity. Development of stress tolerant genotypes is the only way to escape from these environmental constraints. We identified sixteen homologs of the Arabidopsis JUB1 gene in cotton. Expression of GhJUB1_3-At was significantly induced in the temporal expression analysis of GhJUB1 genes in the roots of drought tolerant (H177) and susceptible (S9612) cotton genotypes under drought. The silencing of the GhJUB1_3-At gene alone and together with its paralogue GhJUB1_3-Dt reduced the drought tolerance in cotton plants. The transgenic lines exhibited tolerance to the drought and salt stress as compared to the wildtype (WT). The chlorophyll and relative water contents of wildtype decreased under drought as compared to the transgenic lines. The transgenic lines showed decreased H2O2 and increased proline levels under drought and salt stress, as compared to the WT, indicating that the transgenic lines have drought and salt stress tolerance. The expression analysis of the transgenic lines and WT revealed that GAI was upregulated in the transgenic lines in normal conditions as compared to the WT. Under drought and salt treatment, RAB18 and RD29A were strongly upregulated in the transgenic lines as compared to the WT. Conclusively, GhJUB1_3-At is not an auto activator and it is regulated by the crosstalk of GhHB7, GhRAP2-3 and GhRAV1. GhRAV1, a negative regulator of abiotic stress tolerance and positive regulator of leaf senescence, suppresses the expression of GhJUB1_3-At under severe circumstances leading to plant death.

RÉSUMÉ

The polysaccharides of edible mushrooms are excellent phytochemicals for adjuvant treatment of metabolic diseases, but the potential mechanisms of synergistic effects are unclear. In this work, we discovered that NAP-3 enhanced the efficiency of metformin in lipid and glucose metabolism in type 2 diabetic (T2D) mice in a gut microbiome-dependent way. NAP-3 remodeled the intestinal microbial, resulting in the decreased activity of bile salt hydrolases and upregulation of CYP27A1 and CYP7B1 functions in the alternative pathway of bile acid synthesis, which leads to accumulation of the conjugated bile acids in ileum, specifically TßMCA and TUDCA. The accumulated conjugated bile acids either blocked or stimulated the nuclear receptors Farnesoid-X-receptor and TGR5, inducing the release of GLP-1 and ultimately enhanced glucose metabolism in mice. Collectively, our research indicated that edible mushroom polysaccharide NAP-3 may serve as a promising adjunctive oral therapeutic agent for T2D.

RÉSUMÉ

Hepatocellular carcinoma (HCC) is one of the leading causes of cancer-related deaths in the United States, with a median survival period of approximately 10 months. There is an urgent need for the development of effective targeted therapies for the treatment of HCC. Proline-, glutamic acid- and leucine-rich protein 1 (PELP1) signaling is implicated in the progression of many cancers, although its specific contribution to the progression of HCC is not yet well understood. Analysis of TCGA HCC gene expression data sets and immunohistochemistry analysis of HCC tissue microarray revealed that HCC tumors had elevated expression of PELP1 compared to normal tissues, and high expression of PELP1 is associated with unfavorable survival outcomes. Suppression of PELP1 expression using shRNA significantly reduced the cell viability, clonogenicity, and invasion of HCC cells. Importantly, SMIP34, a first-in-class small molecule inhibitor targeting PELP1, effectively decreased the cell viability, clonogenic survival and invasiveness of HCC cells. Gene expression analysis using RNA-seq revealed that PELP1-knockdown (KD) cells exhibited a decrease in c-Myc, E2F, and other oncogenic pathways related to HCC. Mechanistic studies showed that SMIP34 treatment impaired the Rix complex, a critical component of ribosomal biogenesis, in HCC cells. Further, the knockdown or pharmacological inhibition of PELP1 significantly decelerated the HCC tumor growth in xenograft models. In summary, our study findings indicate that PELP1 could serve as a promising target for therapeutic intervention in HCC.

RÉSUMÉ

Fluoride (F) and cadmium (Cd) as well known environmental pollutants can cause nephrotoxicity to damage human health, while the joint toxicity of F and Cd to the renal tubular epithelial cells remains still elusive. The interactive influence between F and Cd in oxidative stress, apoptosis, and mitochondrial autophagy of renal tubular epithelial cells was explored. Cells were submitted to varying concentrations with of NaF (1, 5, 10, and 15 µg/mL) combined with CdCl2·2.5H2O (1 µg/mL) for 12 h. Following this, the combined cytotoxicity was assessed. Our results show that different doses of F had varying effects on Cd-mediated nephrotoxicity, with a synergistic effect observed in the high F (15 µg/mL) co-treated with Cd. In response to the Cd induction, the high F treatment resulted in the formation of multiple autophagosomes and notably increased the levels of LDH, ROS, and MMP. It also elevated the MDA contents while decreasing the activities of SOD, GSH-Px, and CAT. Additionally, it yielded a higher Bax/Bcl-2 ratio, which further promotes the apoptotic process. The treatment also disturbed energy metabolism, resulting in a reduction of both ATP and ADP. Furthermore, autophagy-related genes and proteins, including PINK1, Parkin, LC3A, LC3B, and SQSTM1, were significantly improved. In brief, high F of 15 µg/mL aggravated Cd-mediated nephrotoxicity of renal tubular epithelial cells via the ROS-PINK1/Parkin pathway.

RÉSUMÉ

Background: Extracorporeal circulation auxiliary to open cardiac surgery (ECAOCS) is one of the most complex surgical procedures and carries a very high risk of death. We developed a nomogram from a retrospective study to predict the risk of death during patient hospitalization. Methods: All clinical data were extracted from the Medical Information Mart for Intensive Care IV (MIMIC-IV) database. We extracted clinical variables for the first 24 hours after admission to the intensive care unit (ICU) in a total of 880 patients who underwent ECAOCS. All patients were randomly divided into training and validation cohort in a ratio of 7:3. All variables included in the study were subjected to univariate logistic regression analysis. In order to prevent overfitting and to address the problem of severe covariance, all factors with P<0.05 in the univariate logistic regression analysis were analyzed using the least absolute shrinkage and selection operator (LASSO) regression. A multivariate logistic regression model was developed based on the factors output from the LASSO regression and a nomogram was plotted. The receiver operating characteristic (ROC) curve was constructed and the area under the curve (AUC) was calculated in training and validation cohort. Finally, the evaluation of the model was performed by calibration curves and Hosmer-Lemeshow goodness-of-fit test (HL test) and decision curve analysis (DCA) was performed. Results: Indicators included in the nomogram were anion gap (AG), central venous pressure (CVP), glucose, creatinine (Cr), prothrombin time (PT), activated partial thromboplastin time (APTT), bicarbonate ion (HCO3 -), cerebrovascular disease (CVD), peripheral vascular disease (PVD), and acute myocardial infarction (AMI). Conclusions: Our study developed a model for predicting postoperative hospital mortality in patients underwent ECAOCS by incorporating AG, CVP, glucose, Cr, APTT, HCO3 -, CVD, AMI, and PVD from the first 24 hours after admission to the ICU. Keywords: Extracorporeal circulation; cardiac surgery; intensive care; nomogram; prediction model.

RÉSUMÉ

BACKGROUND: To investigate the cross-sectional and longitudinal associations between depressive symptoms and the prevalence of frailty and its components in a nationally representative sample of middle-aged and older Chinese adults. METHOD: The China Health and Retirement Longitudinal Study (CHARLS) provided data on 2581 (after inclusion and exclusion criteria) adults aged ≥ 45 years. Every two years, face-to-face, computer-aided personal interviews (CAPI), and structured questionnaires were used to follow up with the respondents. The Chinese version of the Center for Epidemiologic Studies-Depression Scale (CES-D) was used to evaluate depressive symptoms, and the Fried criteria were used to measure frailty. The odds ratio (OR) and 95% confidence interval (CI) for the association of exposure (depressive symptoms at baseline) with the onset of the outcome (frailty and its components) in the individuals at baseline were analyzed by binary logistic regression. RESULTS: At baseline, 11.62% of participants had frailty, and 57.92% had depressive symptoms. In the cross-sectional analysis, depressive symptoms (OR = 5.222, 95%CI 3.665-7.442) were associated with frailty. In the longitudinal analysis, after adjusting for the full set of covariates among participants free of baseline frailty, depressive symptoms were significantly associated with incident frailty during the short term (OR = 2.193, 95%CI 1.324-3.631) and the long term (OR = 1.926, 95%CI 1.021-3.632). Meanwhile, depressive symptoms were associated with an increased risk of weakness (OR = 1.990, 95%CI 1.250-3.166), slowness (OR = 1.395, 95%CI 1.044-1.865), and exhaustion (OR = 2.827, 95%CI 2.150-3.719) onset during the short-term. Depressive symptoms were associated with an increased risk of exhaustion (OR = 2.869, 95%CI 2.004-4.109) onset during the long-term. CONCLUSION: Among middle-aged and older adults, depressive symptoms could predict frailty during 2 years of follow-up and 4 years of follow-up. When considering potential confounding factors, depressive symptoms were considered a predictor of weakness, slowness, and exhaustion. Interventions aimed at preventing depressive symptoms may be beneficial in reducing frailty and its components.

RÉSUMÉ

BACKGROUND: Preeclampsia is a severe obstetric disorder that significantly affects the maternal and neonatal peri-partum safety and long-term quality of life. However, there is limited research exploring the common mechanisms and potential clinical significance between early-onset preeclampsia and full-term preeclampsia from an immunological perspective. METHODS: In this study, data analysis was conducted. Initially, immune-related co-expressed genes involving both subtypes of preeclampsia were identified through Weighted Gene Co-expression Network Analysis (WGCNA). Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) analyses were further employed to investigate the shared pathways regulated by immune-related genes. Binary logistic regression identified co-expressed genes with diagnostic value for preeclampsia, and a diagnostic model was constructed. Gene Set Enrichment Analysis (GSEA) predicted the potential biological functions of the selected genes. Lasso and Cox regression analyses identified genes closely associated with gestational duration, and a risk score model was established. A 4-gene feature, immune-related gene model for predicting the risk of preterm birth in preeclamptic pregnant women, was developed and validated through qPCR experiments. Immune cell infiltration analysis determined differences in immune cell infiltration between the two subtypes of preeclampsia. RESULTS: This study identified 4 immune-related co-expressed genes (CXCR6, PIK3CB, IL1RAP, and OSMR). Additionally, diagnostic and preterm birth risk prediction models for preeclampsia were constructed based on these genes. GSEA analysis suggested the involvement of these genes in the regulation of galactose metabolism, notch signaling pathway, and RIG-I like receptor signaling pathway. Immune pathway analysis indicated that the activation of T cell co-inhibition could be a potential intervention target for immunotherapy in early-onset preeclampsia. CONCLUSION: Our study provides promising insights into immunotherapy and mechanistic research for preeclampsia, discovering novel diagnostic and intervention biomarkers, and offering personalized diagnostic tools for preeclampsia.

RÉSUMÉ

BACKGROUND: Considering that changes in the choroidal thickness are closely related to ocular growth, we studied the choroidal thickness (CT) and the blood flow features in children with unilateral myopic anisometropia (UMA) as well as investigating the relationship between choroidal changes and myopia. METHODS: Subjective refractive, axial length (AL), and biometric parameters were measured in 98 UMA children (age: 8-15 years). CT and choroidal blood-flow features, including the choroidal vessel volume (CVV), choroidal vascularity index (CVI), and choriocapillaris perfusion area (CCPA), were measured through swept-source optical coherence tomography angiography. The macular region was categorized into four concentric circles of diameters 0-1 mm (central fovea), 1-3 mm (parafovea), 3-6 mm (perifovea), and 6-9 mm (extended), and further categorized into superior (S), inferior (I), temporal (T), and nasal (N) quadrants. RESULTS: The aforementioned four regions of myopic eyes displayed significantly lower CT, CVV, and CVI than those of non-myopic eyes. CCPA changes differed across different regions of both the eyes (parts of N and T quadrants). There was an inverse association between CT and the interocular AL difference (central and other regions S, T quadrant). No correlation was noted between CVV and CVI with interocular AL difference. CT and CVV were positively correlated in the 0-6-mm macular region of myopic eyes (Spearman correlation coefficient = 0.763, P < 0.001). CONCLUSIONS: In UMA children, CCT and blood flow may be related to myopia progression. A robust correlation between CT and CVV in the 0-6-mm macular region and reduced CT and diminished blood flow indicated an association with myopia.

RÉSUMÉ

BACKGROUND: The prognostic potential of immune-related genes, particularly immune checkpoint inhibitors (ICIs) and long non-coding RNAs (lncRNAs), is gaining attention for evaluating the prognosis of breast cancer patients. METHODS: We analyzed 23 datasets to identify 15 ICI-related mRNAs and 5 immune-related lncRNAs, creating a robust immune score (IS). This score was used to classify patients into high and low IS groups and assess their survival outcomes. RESULTS: Patients with high IS showed significantly poorer overall survival (OS) and progression-free survival (PFS) compared to those with low IS. Multivariate Cox regression analysis confirmed IS as an independent prognostic factor. Additionally, high IS was associated with higher mutation loads and neoantigen profiles, while low IS correlated with enhanced immune cell infiltration. CONCLUSIONS: The immune score developed from ICI-related mRNAs and lncRNAs effectively predicts the prognosis of breast cancer patients and highlights the differential immune and inflammatory responses between patients with varying levels of immune score. This underscores the relevance of IS in guiding therapeutic decisions and tailoring patient management strategies in clinical settings.

RÉSUMÉ

Malnutrition early in life may have adverse effects on health later in life. The relationship between malnutrition and obesity parameters (body mass index [BMI] and waist circumference [WC]) and type 2 diabetes is inconsistent. This study aimed to identify the effects of famine exposure and obesity parameters on type 2 diabetes individually or in combination among middle-aged and older adults in China. Data were extracted from the China Health and Retirement Longitudinal Study Wave1 in 2011. The sample involved 13,065 adults aged 45 to 90. The t- or F test was employed to compare age among groups. The chi-square test was utilized to compare baseline characteristics according to the categorical WC levels/BMI levels/famine exposure and examine between-group differences in type 2 diabetes (diabetes and non-diabetes). Odds ratio (OR) and 95% confidence interval (CI) were estimated by logistic regression models to estimate the individual and combined associations of BMI/WC levels and famine exposure with the prevalence of type 2 diabetes. In this study, 1559 (11.93%) individuals were exposed to Chinese famine during their fetal stage, 5132 (39.28%) and 4428 (33.89%) in childhood and adolescence/adulthood, respectively. Among BMI measurements, 3780 (28.93%) were overweight, and 1487 (11.38%) were obese, whereas WC measurements showed that 5408 (41.39%) were obesity. In addition, 831 (45.48%) males and 996 (54.52%) females reported type 2 diabetes. In multivariable-adjusted regression models, obesity parameters and famine exposure were independently associated with type 2 diabetes prevalence among all participants (P < .001). In the interaction analysis, there existed a trend of higher odds for prevalence of type 2 diabetes across all groups compared to the combination of no-exposed and normal BMI/WC level group (the most increase in odds, adolescence/adulthood-exposed group with central obesity in WC levels: OR 4.51 (95% CI = 3.42-5.95); adolescence/adulthood-exposed group with obesity in BMI levels: OR 5.84 (95% CI = 4.11-8.30; P for interaction <.001). The findings for females exhibited similar to the overall participants, when by gender stratification. Our results suggest famine exposure and obesity parameters have positive combined effects on type 2 diabetes in middle-aged and older adults in China.

RÉSUMÉ

Inflammatory processes in the brain can exert important neuroprotective functions. However, in neurological and psychiatric disorders, it is often detrimental due to chronic microglial over-activation and the dysregulation of cytokines and chemokines. Growing evidence indicates the emerging yet prominent pathophysiological role of neuroinflammation in the development and progression of these disorders. Despite recent advances, there is still a pressing need for effective therapies, and targeting neuroinflammation is a promising approach. Therefore, in this study, we investigated the anti-neuroinflammatory potential of a marketed and quantified proprietary herbal extract of Ginkgo biloba leaves called EGb 761 (10-500 µg/mL) in BV2 microglial cells stimulated by LPS (10 ng/mL). Our results demonstrate significant inhibition of LPS-induced expression and release of cytokines tumor necrosis factor-α (TNF-α) and Interleukin 6 (IL-6) and chemokines C-X-C motif chemokine ligand 2 (CXCL2), CXCL10, c-c motif chemokine ligand 2 (CCL2) and CCL3 in BV2 microglial cells. The observed effects are possibly mediated by the mitogen-activated protein kinases (MAPK), p38 MAPK and ERK1/2, as well as the protein kinase C (PKC) and the nuclear factor (NF)-κB signaling cascades. The findings of this in vitro study highlight the anti-inflammatory properties of EGb 761 and its therapeutic potential, making it an emerging candidate for the treatment of neuroinflammatory diseases and warranting further research in pre-clinical and clinical settings.

RÉSUMÉ

BACKGROUND AND OBJECTIVE: Cerebral small vessel disease (CSVD) often coexists with cognitive dysfunction in patients, leading to significant challenges in treatment and management. This study aimed to examine the efficacy of combined application of donepezil and nimodipine on patients with comorbid CSVD and cognitive dysfunction and the effects on patients' albumin and prealbumin levels. METHODS: The records of 112 patients with comorbid CSVD and cognitive dysfunction treated at the People's Hospital of Suzhou New District from January 2019 to December 2022 were analysed retrospectively. A total of 50 patients receiving donepezil were allocated to the control group, and 62 patients receiving both nimodipine and donepezil to the study group. Outcomes compared between the two groups included serum homocysteine (Hcy), high sensitivity C-reactive protein (hs-CRP), albumin, and prealbumin before and after therapy, efficacy, and adverse reactions. Additionally, logistic regression was performed to analyze the risk factors impacting patient prognosis. RESULTS: Prior to therapy, the two groups did not differ significantly in Hcy and hs-CRP levels (p > 0.05), whereas after therapy, the levels in both groups dropped significantly (p < 0.01), with more obvious lower levels in the study group (p < 0.05). After treatment, the study group presented significantly higher albumin and prealbumin levels than the control group (p < 0.001). An obvious higher overall response rate was observed in the study group compared to the control group (p = 0.012). No significant inter-group discrepancy was found regarding the total incidence of adverse reactions (p = 0.752). Univariate analysis identified age, course of disease, heart rate (HR), Montreal Cognitive Assessment (MoCA) score, diastolic blood pressure (DBP), systolic blood pressure (SBP), drinking history, as well as medication regimen as risk factors impacting patient prognosis. Multivariate logistic regression analysis identified SBP, DBP, and medication regimen as the independent risk factors. CONCLUSION: Combined application of donepezil and nimodipine can effectively treat patients with comorbid CSVD and cognitive dysfunction. It can significantly lower the Hcy and hs-CRP levels and improve the nutritional status without increasing the frequency of adverse reactions. In addition, for CSVD patients with cognitive dysfunction, age, course of disease, MoCA score, HR, SBP, DBP, drinking history, and medication regimen are risk factors impacting patient prognosis, while SBP, DBP, and medication regimen are independent risk factors.

RÉSUMÉ

Background: Previous structural neuroimaging studies linked cerebellar deficits to temporal lobe epilepsy (TLE). The functions of various cerebellar regions are increasingly being valued, and their changes in TLE patients warrant further in-depth investigation. In this study, we used the Spatially Unbiased Infratentorial (SUIT) toolbox with a new template to evaluate the cerebellar structural abnormalities in patients with TLE, and further explored the relationship between the changes of different cerebellar regions and cognition. Methods: Thirty-two patients with TLE were compared with 39 healthy controls (HC) matched according to age, gender, handedness, and education level. All participants underwent a high-resolution T1-weighted MRI scan on a 3.0 Tesla scanner. We used a voxel-based morphometry (VBM) approach utilizing the SUIT toolbox to provide an optimized and fine-grained exploration of cerebellar structural alterations associated with TLE. Results: Compared with HC, TLE patients showed a significant reduction in the volume of gray matter in the Left lobule VI and white matter in the Right Crus II. In the TLE patient group, we conducted partial correlation analysis between the volumes of different cerebellar regions and cognitive rating scale scores, such as MMSE and MoCA. The volume of the Left lobule VI (GM) exhibited a positive correlation with the MMSE score, but no significant correlation was found with the MoCA score. On the other hand, there was no significant correlation observed between the volume of the Right Crus II (WM) and the two cognitive scale scores mentioned above. Furthermore, it was observed that the MMSE was more effective than the MoCA in identifying epilepsy patients with cognitive impairment. Conclusion: This study supported previous research indicating that temporal lobe epilepsy (TLE) is linked to structural changes in the cerebellum, specifically affecting the volume of both gray and white matter. These findings offer valuable insights into the neurobiology of TLE and hold potential to inform the development of enhanced diagnostic methods and more effective treatment approaches.

RÉSUMÉ

BACKGROUND: Calcium silicate-based bioceramics have been applied in endodontics as advantageous materials for years, many chemical components and new synthesizing methods were used to improve the base formulation of the materials for positively affecting the sealers properties. Recently, a novel biomaterial formulation, grounded in strontium silicate, has been introduced to the market, offering potential advancements in the field. OBJECTIVE: To comparatively analyze the cytotoxicity and cell migration effects of a novel strontium silicate-based bioceramic material (CRoot SP) and those of calcium silicate-based (iRoot SP) and epoxide amine resin (AH Plus) sealers on stem cells derived from rat apical papilla(rSCAPs). METHODS: rSCAPs were isolated and characterized in vitro and subsequently cultured in the presence of various concentrations of CRoot SP, iRoot SP and AH Plus extracts. Cytotoxicity was assessed by CCK-8 assay, and cell-migration capacity was assessed by using wound healing assays . RESULTS: No significant differences in cell viability were observed in the 0.02 mg/mL and 0.2 mg/mL sealer groups. The cell viability of CRoot SP was consistently greater than that of iRoot SP at concentrations of 5 mg/mL and 10 mg/mL across all time points. Maximum cytotoxic effect was noted on day 5 with 10 mg/mL AH Plus.The scratch was partly healed by cell migration in all groups at 24 h, and the 0.02 mg/mL, and 0.2 mg/mL CRoot SP exerted beneficial effects on rSCAPs migration. CONCLUSIONS: CRoot SP exhibited less cytotoxic than the iRoot SP and AH Plus extracts after setting. A lower concentration of CRoot SP thus promotes the cell migration capacity of rSCAPs, and it may achieve better tissue repair during root canal treatment.

RÉSUMÉ

BACKGROUND: Enterococcus gallinarum is an infrequently intestinal symbiotic pathogen associated with nosocomial infection in immunocompromised individuals. To date, rare cases of pulmonary infection attributable to Enterococcus gallinarum were reported. Herein, we presented the first case of empyema resulting from Enterococcus gallinarum infection. CASE PRESENTATION: An 81-year-old male presented with fever and dyspnea upon admission. Chest CT scan and thoracic ultrasonography confirmed the presence of right pleural effusion. Thoracoscopy revealed extensive adhesion, purulent fluid, and necrotic materials within the thoracic cavity. Enterococcus gallinarum was identified through pleural effusion culture. The patient underwent an intrathoracic injection of urokinase along with thoracic drainage. Following surgery, He took oral linezolid for over one month. Undergoing comprehensive treatment, the patient exhibited favorable recovery. CONCLUSIONS: We reported the first case of empyema due to Enterococcus gallinarum infection. It should be suspected in patients with impaired immune function and invasive therapies, without responding to conventional anti-infectious treatment.

RÉSUMÉ

Magnetoresistance effects are crucial for understanding the charge-spin transport as well as propelling the advancement of spintronic applications. Here, we report the coexistence of magnetic-moment-dependent (MD) and magnetic-field-driven (FD) unidirectional magnetoresistance (UMR) effects in CoFeB/InSb/CdTe heterostructures. The strong spin-orbital coupling of InSb and the matched impedance at the CoFeB/InSb interface warrant a distinct MD-UMR effect at room temperature, while the interaction between the in-plane magnetic field and the Rashba effect at the InSb/CdTe interface induces the marked FD-UMR signal that dominates the high-field region. Moreover, owning to different spin scattering mechanisms, these two types of non-reciprocal charge transports show opposite polarities with respect to the magnetic field direction, which further enables an effective phase modulation of the angular-dependent magnetoresistance. The demonstration of the tunable UMR response validates our CoFeB/InSb/CdTe system as a suitable integrated building block for multifunctional spintronic memory and sensor designs.

RÉSUMÉ

BACKGROUND: The incidence and mortality rates of hepatocellular carcinoma (HCC) among Hispanic individuals in the United States are much higher than in non-Hispanic white people. We conducted multi-omics analyses to elucidate molecular alterations in HCC among Hispanic patients. METHODS: Paired tumor and adjacent non-tumor samples were collected from 31 Hispanic HCCs in South Texas (STX-Hispanic) for genomic, transcriptomic, proteomic, and metabolomic profiling. Serum lipids were profiled in 40 Hispanic and non-Hispanic patients with or without clinically diagnosed HCC. RESULTS: Exome sequencing revealed high mutation frequencies of AXIN2 and CTNNB1 in STX Hispanic HCCs, suggesting a predominant activation of the Wnt/ß-catenin pathway. TERT promoter mutations were also significantly more frequent in the Hispanic cohort (Fisher's exact test, p < .05). Cell cycles and liver function were positively and negatively enriched, respectively, with gene set enrichment analysis. Gene sets representing specific liver metabolic pathways were associated with dysregulation of corresponding metabolites. Negative enrichment of liver adipogenesis and lipid metabolism corroborated with a significant reduction in most lipids in serum samples of HCC patients (paired t-test, p < .0001). Two HCC subtypes from our Hispanic cohort were identified and validated with the TCGA liver cancer cohort. Patients with better overall survival showed higher activity of immune and angiogenesis signatures, and lower activity of liver function-related gene signatures. They also had higher levels of immune checkpoint and immune exhaustion markers. CONCLUSIONS: Our study revealed specific molecular features of Hispanic HCC and potential biomarkers for therapeutic management. It provides a unique resource for studying Hispanic HCC.

RÉSUMÉ

INTRODUCTION: Balloon pulmonary angioplasty (BPA) is an effective intervention for patients with chronic thromboembolic pulmonary disease (CTEPD). We aimed to identify the patient group with a low success rate or high complication rate of BPA, which is still unclear. METHODS: Both CTEPD patients with or without pulmonary hypertension (CTEPH and NoPH-CTEPD) were included. CTEPH patients were divided into groups with or without pulmonary endarterectomy (PEA-CTEPH and NoPEA-CTEPH). The efficacy and safety of BPA were compared among the groups. RESULTS: There were 450, 66, and 41 sessions in the NoPEA-CTEPH, PEA-CTEPH, and NoPH-CTEPD groups, respectively. The success rate (≥1 degree improvement in flow grade) in the PEA-CTEPH group was 94.5%, significantly lower than that in the NoPEA-CTEPH (97.1%) and NoPH-CTEPD (98.4%) groups (p = 0.014). The percentage of complete flow recovery in treated vessels was also lower in PEA-CTEPH group. BPA-related complication rate in NoPEA-CTEPH, PEA-CTEPH, and NoPH-CTEPD patients was 6.1%, 6.0%, and 0.0%, respectively (p = 0.309). One BPA-related death occurred (solely in NoPEA-CTEPH). Mean pulmonary artery pressure ≥41.5 mm Hg was a predictor of BPA-related complications. NoPEA-CTEPH patients had more improvement in 6-min walk distance (6MWD, 87 ± 93 m NoPEA-CTEPH vs. 40 ± 43 m PEA-CTEPH vs. 18 ± 20 m NoPH-CTEPD, p = 0.012). CONCLUSIONS: BPA was safe and effective for all CTEPD groups with less improvement for the PEA-CTEPH and NoPH-CTEPD groups. The success rate of BPA was lower in the PEA-CTEPH group and the complication rate was lower in the NoPH-CTEPD group. Pre-BPA treatment to lower pulmonary artery pressure should not be overlooked in CTEPD patients.

RÉSUMÉ

BACKGROUND: Ripretinib, a recently developed tyrosine kinase inhibitor with switch-control abilities, can inhibit both primary and secondary activation of KIT(KIT proto-oncogene receptor tyrosine kinase) and platelet-derived growth factor receptor alpha (PDGFRA) mutants, which contribute to gastrointestinal stromal tumor progression. METHODS: In this study, a high-performance liquid chromatography-tandem mass spectrometry method to measure the concentrations of ripretinib and its active desmethyl metabolite DP-5439 in human plasma was developed and validated. Plasma samples were extracted and recovered by precipitation with acetonitrile containing the internal standard and diluted with acetonitrile before analysis. Ripretinib and DP-5439 were separated using chromatography on a Waters ACQUITY UPLC HSS T3 column (2.1 mm × 50 mm, 1.8 µm) with gradient elution using 0.1% formic acid and 5 mM ammonium formate in water as mobile phase A and acetonitrile as mobile phase B. The mobile phase was set to a flow rate of 0.5 mL/min. RESULTS: The calibration curves were linear across the following concentration range: 7.5 to 3000 ng/mL for ripretinib and 10 to 4000 ng/mL for DP-5439. The intraday and interday precisions were approximately 15% for all analytes in the quality control samples. The relative matrix effects in extracted plasma samples (90.3%-108.8% at different levels) were considered acceptable. CONCLUSIONS: This method will be a useful tool in oncology to facilitate the further clinical development of ripretinib.
