RESUMO

Affective picture databases with a single facial expression or body posture in one image have been widely applied to investigate emotion. However, to date, there was no standardized database containing the stimuli which involve multiple emotional signals in social interactive scenarios. The current study thus developed a pictorial set comprising 274 images depicting two Chinese adults' interactive scenarios conveying emotions of happiness, anger, sadness, fear, disgust, and neutral. The data of the valence and arousal ratings of the scenes and the emotional categories of the scenes and the faces in the images were provided in the present study. Analyses of the data collected from 70 undergraduate students suggested high reliabilities of the valence and arousal ratings of the scenes and high judgmental agreements in categorizing the scene and facial emotions. The findings suggested that the present dataset is well constructed and could be useful for future studies to investigate the emotion recognition or empathy in social interactions in both healthy and clinical (e.g., ASD) populations.

RESUMO

A 65-year-old woman presented to our hospital with 5 days of chest tightness, dyspnoea, and lower abdominal distension. Echocardiography revealed a mass in the right atrium. An emergency operation was carried out to prevent tumour shedding. The patient was discharged on the 4th day of tumour resection, without any complications At the 18 months follow-up, she suffered from kidney and lung tumours. She refused any treatment and passed away. scRNA-seq was applied to analyse the nature of the tumour. The cellular components of benign tumours include chondrocytes, smooth muscle cells, fibroblasts, mesenchymal stromal cells, and osteoblasts. Additionally, the cyclic guanosine monophosphate (cGMP-PKG) signalling pathway, transcriptional misregulation in cancer, and the p53 signalling pathway may be related to the growth of this tumour. scRNA-seq is a good approach to analyse growth patterns of cardiac tumours and helpful for distinguishing the nature of the tumour.

RESUMO

PURPOSE: The present research aims to study the effects of swaddled and traditional tub bathing on premature infants to identify better ways to bathe. DESIGN AND METHODS: Eligible premature infants (n = 60) were randomly assigned to either swaddled bathing or traditional tub bathing group. Stress scores and physiological indicators were measured 10 min before, immediately after, and 10 min after bathing. Crying times were also recorded for both groups. Data were reported as mean and standard deviation (SD) or frequency (percentage). For analyzing the data, the Student t-test and Chi-square test were employed. RESULTS: Swaddled bathing has less effect on the respiratory rate, heart rate, and oxygen saturation (p < 0.05). Both bathing methods led to a decrease in the temperature of infants. Still, the temperature of infants 10 min after bathing, in the swaddled bathing group was rose higher than the traditional tub bathing (t = 2.813, p < 0.05). The stress score of the swaddled bathing group, immediately after and ten minutes after bathing was lower than the traditional tub bathing group. The crying time of the swaddled bathing group was 32 ± 24.740(s) lower than the traditional tub bathing group 94.43 ± 41.625(s). CONCLUSIONS: The advantages of swaddled bathing over traditional tub bathing were validated for feasibility in China's preterm infants. Swaddled bathing is recommended method for bathing technique in the neonatal intensive care unit. PRACTICE IMPLICATIONS: Swaddled bathing is beneficial for the development of premature infants, as it results in less noxious stimuli and stress on the developing premature neonates.

RESUMO

The release of paracrine factors from endothelial progenitor cell (EPC) sheet is a central mechanism of tissue repair. The purpose of this study was to constuct the rat bone marrow derived-endothelial progenitor cell (BM-EPCs) sheet and investigate invest the role of stromal cell-derived factor-1α (SDF-1α)/CXCR4 axis in the biological function of BM-EPCs sheet. BM-EPC cells were identified by the cell-surface markers-CD34/CD133/VE-cadherin/KDR using flow cytometry and dual affinity for acLDL and UEA-1. After 7 days of incubation, the BM-EPC single-cell suspensions were seeded on thermo-sensitive plate to harvest the BM-EPC cell sheets. The expression levels of SDF-1α/CXCR4 axis-associated genes and proteins were examined using RT-qPCR and western blot analysis, and enzyme-linked immunosorbent assay (ELISA) was applied to determine the concentration of vascular endothelial growth factor (VEGF), epidermal growth factor (EGF) and SDF-1α in the cell culture medium. The BM-EPC cell sheets were successfully harvested. Moreover, BM-EPC cell sheets have superior migration and tube formation activity when compared with single cell suspension. When capillary-like tube were formed from EPCs sheets, the releasing of paracrine factors such as VEGF, EGF and SDF-1α were increased. To reveal the mechanism of tube formation of BM-EPCs sheets, our research showed that the activation of PI3K/AKT/eNOS pathway was involved in the process, because the phosphorylation of CXCR, PI3K, AKT and eNOS were increased. BM-EPC cell sheets have superior paracrine and tube formation activity than the BM-EPC single-cell. The strong ability to secrete paracrine factors was be potentially related to the SDF-1α/CXCR4 axis through PI3K/AKT/eNOS pathway.

RESUMO

Doxorubicin (DOX) is a highly efficient chemotherapeutic drug limited by its cardiotoxicity. Galectin-3 (Gal-3) overexpression is associated with several cardiovascular diseases. In this study, the in vivo models of DOX-treated rats and the in vitro model of DOX-treated H9C2 cells were used. DOX induced cardiac injury and dysfunction accompanied with the upregulation of Gal-3 at the end of the experiment, while inhibition of Gal-3 with modified citrus pectin (MCP) exhibited a dramatic improvement in cardiac function of the DOX-treated rats, as manifested by increased left ventricular systolic pressure and ±dp/dtmax and decreased left ventricular end-diastolic pressure. The plasma levels of myocardial injury markers such as lactate dehydrogenase, creatine kinase, creatine kinase-MB, and cardiac troponin I were decreased after MCP treatment. In parallel, MCP attenuated myocardial tissue markers of oxidative stress such as hydrogen peroxide and malondialdehyde restored the activities of superoxide dismutase, catalase, and glutathione peroxidase and upregulated antioxidant peroxiredoxin-4 (Prx-4). To further verify the role of Prx-4, it was downregulated by siRNA-mediated knockdown in H9C2 cells. MCP could not reverse DOX-induced oxidative stress in Prx-4-knock-down cells. In conclusion, Gal-3 mediated DOX-induced cardiotoxicity and Gal-3 inhibition attenuated DOX-induced cardiac dysfunction by upregulating the expression of Prx-4 to reduce myocardial oxidative stress.

RESUMO

Intestinal stem cells are primitive cells found within the intestinal epithelium that play a central role in maintaining epithelial homeostasis through self-renewal and commitment into functional epithelial cells. Several markers are available to identify intestinal stem cells, such as Lgr5, CD24 and EphB2, which can be used to sort intestinal stem cells from mammalian gut. Here, we identify and isolate intestinal stem cells from C57BL/6 mice by using a cell surface antigen, CD44. In vitro, some CD44(+) crypt cells are capable of forming "villus-crypt"-like structures (organoids). A subset strongly positive for CD44 expresses high levels of intestinal stem-cell-related genes, including Lgr5, Bmi1, Hopx, Lrig1, Ascl2, Smoc2 and Rnf43. Cells from this subset are more capable of developing into organoids in vitro, compared with the subset weakly positive for CD44. However, the organoids are sensitive to ionizing irradiation. We investigate the specific roles of mesenchymal stem cells in protecting organoids against radiation-induced crypt death. When co-cultured with mesenchymal stem cells, the crypt domains of irradiated organoids possess more proliferative cells and fewer apoptotic cells than those not co-cultured with mesenchymal stem cells. Cd44v6 continues to be expressed in the crypt domains of irradiated organoids co-cultured with mesenchymal stem cells. Our results indicate specific roles of mesenchymal stem cells in delaying radiation-induced crypt death in vitro.

RESUMO

Hypoxic preconditioning is a promising method for improving the anti-apoptotic and paracrine signaling capabilities of adipose-derived stromal cells (ADSCs). The purpose of this study was to analyze the influence of different hypoxic conditions on ADSCs and the therapeutic effects of hypoxia-preconditioned ADSCs (HPADSCs) on an animal model of myocardial infarction (MI). For the in vitro studies, ADSCs were divided into five groups and cultured in different oxygen concentrations (1, 3, 5, 10, and 21 %). After 24 h, RT-PCR and western blots showed that 3 % oxygen preconditioning could improve the viability and cytokine secretion of the ADSCs. A Matrigel assay indicated that the HPADSC-conditioned medium could stimulate endothelial cells to form capillary-like tubes. For the in vivo studies, MI was induced by coronary occlusion in 24 mature Chinese minipigs. The animals were divided into three groups and treated by intramyocardial injection with vehicle alone (saline group), with 1 × 10(8) ADSCs cultured in normoxic conditions (ADSCs group) or with 1 × 10(8) ADSCs precultured in 3 % oxygen (HPADSCs group). SPECT and echocardiography demonstrated that cardiac function was improved significantly in the HPADSC transplant group compared with the vehicle control group (P < 0.05). Immunofluorescence showed fewer apoptotic cells and more small- to medium-sized vessels in the HPADSC transplantation group (P < 0.05). Three percent oxygen is the optimum preconditioning treatment for ADSCs. HPADSC transplantation can prevent ventricular remodeling and reduce the infarct size.

RESUMO

BACKGROUND: Myocardial ischemia-reperfusion injury (I/R) has been improved with drugs and effective reperfusion, but it still cannot be prevented. METHODS: To investigate whether renal denervation (RDN) reduces cardiomyocyte apoptosis by ameliorating endoplasmic reticulum stress, 60 male specific pathogen-free (SPF) Wistar rats were randomly divided into 6 groups (n = 6). We established the I/R rat model by ligating the left anterior descending artery. The I/R+ angiotensin receptor neprilysin inhibitors (ARNI) group received ARNIs for 2 weeks until euthanasia. RESULTS: The I/R+RDN and I/R+ARNI groups have significantly ameliorated left ventricular ejection fraction (LVEF) and left ventricular fractional shortening (LVFS) and reversed expansion of the left ventricular end-systolic diameter (LVSD) and left ventricular end diastolic diameter (LVDD) compared to the I/R group. The levels of norepinephrine (NE), angiotensin II, and aldosterone (ALD) increased significantly in the I/R group, but decreased significantly after RDN and ARNI intervention. In the I/R+RDN and I/R+ARNI groups, the myocardial tissue edema was alleviated. The infarct size was smaller in the I/R+RDN and I/R+ARNI groups compared to the I/R group. Apoptosis of cardiomyocytes and fibroblasts in myocardial tissue increased significantly in the I/R group, which was greatly diminished by RDN and ARNI. The expression of Bax, caspase-3, CHOP, PERK, and ATF4 protein was significantly increased in the I/R group, which compared to other groups, and the level of CHOP, PERK, and ATF4 gene expression increased. After RDN intervention, these expression levels recovered to varying degrees. CONCLUSION: The effect of RDN may be associated with regulating the endoplasmic reticulum stress PERK/ATF4 signaling pathway.

RESUMO

In recent years, sleep problems among college students have become increasingly prominent, especially in the context of the COVID-19 pandemic, and their sleep quality has deteriorated dramatically, severely affecting their physical and mental health. Numerous research studies have investigated the relationship between mindfulness and sleep quality; however, it is still unclear what psychological process underlies this relationship. In the current study, college students' bed procrastination and self-control as mediating factors in the association between mindfulness and sleep quality were investigated. Using the convenience sampling method, 763 Chinese college students (mean age = 19.48 years, SD = 2.06) were recruited to complete self-reported questionnaires that included the Mindful Attention Awareness Scale, Self-Control Scale, Bed Procrastination Scale, and Sleep Quality Scale. All statistical analyses were performed using SPSS 23.0 software. Results showed that (a) mindfulness was positively associated with sleep quality; (b) both self-control and bed procrastination mediated the relationship between mindfulness and sleep quality, and (c) self-control and bed procrastination sequentially mediated the relationship between mindfulness and sleep quality. These findings collectively suggest a potential mechanism for how mindfulness influences sleep quality, providing a therapeutic target for mindfulness-based interventions aimed at helping college students improve sleep quality.

RESUMO

INTRODUCTION AND OBJECTIVES: To evaluate the impact of dexmedetomidine impact on cardiac surgery-associated acute kidney injury (CSA-AKI), kidney function, and metabolic and oxidative stress in patients undergoing coronary artery bypass grafting with heart-lung machine support. METHODS: A randomized double-masked trial with 238 participants (50-75 years) undergoing coronary artery bypass grafting was conducted from January 2021 to December 2022. The participants were divided into Dex (n=119) and NS (n = 119) groups. Dex was administered at 0.5 mcg/kg over 10minutes, then 0.4 mcg/kg/h until the end of surgery; the NS group received equivalent saline. Blood and urine were sampled at various time points pre- and postsurgery. The primary outcome measure was the incidence of CSA-AKI, defined as the occurrence of AKI within 96hours after surgery. RESULTS: The incidence of CSA-AKI was significantly lower in the Dex group than in the NS group (18.26% vs 32.46%; P=.014). Substantial increases were found in estimated glomerular filtration rate value at T4-T6 (P<.05) and urine volume 24hours after surgery (P<.01). Marked decreases were found in serum creatinine level, blood glucose level at T1-T2 (P<.01), blood urea nitrogen level at T3-T6 (P<.01), free fatty acid level at T2-T3 (P<.01), and lactate level at T3-T4 (P<.01). CONCLUSIONS: Dex reduces CSA-AKI, potentially by regulating metabolic disorders and reducing oxidative stress. Registered with the Chinese Clinical Study Registry (No. ChiCTR2100051804).

RESUMO

Background: Open thoracotomy has been the traditional surgical approach for patients with bronchogenic cysts (BCs). This study aimed to evaluate the safety and efficacy of video-assisted thoracoscopic surgery (VATS) compared to open surgery for the treatment of BCs in adults. Methods: This single-institution, retrospective cohort study included 117 consecutive adult patients who underwent VATS (group A) or open surgery (group B) for BC resection between February 2019 and January 2023. Data regarding clinical history, operation duration, length of hospital stay, 30-day mortality, and recurrence during follow-up were collected and analyzed. Results: Of the total cohort, 103 (88.0%) patients underwent VATS, while 14 (12.0%) patients underwent open surgery. Patients' age in group B were much older than group A (P=0.014), and no significant differences in other demographic and baseline clinical characteristics were observed between the groups. The VATS group had shorter median operation duration (96 vs. 149.5 min, P<0.001) and shorter mean length of hospital stay (5.0±5.5 vs. 8.6±4.0 days, P<0.001). One death occurred in the open surgery group. During a median follow-up of 34 (interquartile range, 20.8-42.5) months, no instances of BC recurrence were observed in either group. Conclusions: Compared to open surgery, VATS is also a safe and efficacious approach for treating BCs in adults. What's more, VATS offered shorter operative times and hospital stays. Considering the minimally invasive, VATS may be a better choice in most patients with bronchial cysts.

RESUMO

Although there is substantial evidence of visual attentional biases in processing weight-related information among individuals with weight dissatisfaction, few studies have examined auditory attentional biases in these individuals. The identification of attentional biases may provide an impetus for interventions to reduce distress, negative body image, and pathological eating patterns among weight-dissatisfied individuals. Therefore, the present study aimed to investigate the attentional biases, as well as the neural consequences, toward auditory weight-related information among weight-dissatisfied young females. In this experiment, young female participants were assigned to an experimental group with high weight dissatisfaction (HWD) and a control group with low weight dissatisfaction (LWD) according to the levels of weight dissatisfaction. Using a spatial cueing paradigm, auditory fatness-related, thinness-related, and neutral household words were presented laterally as cue stimuli, followed by visual stimuli presented at either the cued or uncued location. The results revealed that auditory fatness-related words elicited significantly larger N2ac amplitudes than auditory thinness-related and neutral words in the HWD group. However, for the LWD group, thinness-related words elicited a significantly larger N2ac than fatness-related and neutral words. These results suggest an orienting attentional bias toward auditory fatness-related body words among females with HWD and an orienting attentional bias toward auditory thinness-related words among females with LWD.

RESUMO

Advances in instrumentation and technique have facilitated minimally invasive surgeries for cardiac myxoma treatment. This study aims to compare the clinical outcomes between the thoracoscopic and robotic approaches for myxoma resection. Intraoperative data and postoperative data of 46 patients who underwent either thoracoscopic (n = 15) or robotic (n = 31) cardiac myxoma resection in our center between July 2013 and September 2022 were retrospectively compared. There was no in-hospital death in either group. Meanwhile, the operative time and cardiopulmonary bypass time were significantly shorter in the robotic group than in thoracoscopic group (P = 0.015 and P = 0.035, respectively). Furthermore, shorter ICU stays (P = 0.006), shorter postoperative mechanical ventilation time (P = 0.035) and less thoracic drainage (P = 0.040) were observed in the robotic group. However, the operating room costs and total hospital costs were both significantly lower in thoracoscopic group (P = 0.004 and P = 0.007, respectively). There was no significant difference between two groups regarding the incidence of postoperative complications (P > 0.05). Lastly, a faster return to exercise was noted in robotic group than in thoracoscopic group (Log-Rank χ2 = 4.094, P = 0.043). Both approaches can be safe and feasible for myxoma resection. However, regardless of higher expenses, the robotic myxoma resection approach provides shorter operation time, less postoperative thoracic drainage, and faster recovery than total thoracoscopic technique.

RESUMO

BACKGROUND: Cardiac myxomas are commonly located in the left atrium but rarely affect the right side of the heart. We retrospectively analyzed 28 patients receiving surgical treatment for right heart myxomas at our center and aimed to summarize the clinical features and surgical outcomes of right heart myxomas. METHODS: Between May 2001 and June 2022, 244 patients with sporadic cardiac myxomas underwent complete surgical resection. Twenty-eight patients (28/244, 11.48%) were right heart myxomas. Among the 28 right heart myxoma cases, 25 underwent median sternotomy and 3 underwent robotic or total thoracoscopic procedures. The clinical features, operative information, and follow-up data of right heart myxoma were comprehensively reviewed, and clinical characteristics between right heart myxoma and left heart myxoma were also compared. RESULTS: A significant difference was noted in sex between right heart myxoma and left heart myxoma (P <.05). Right heart myxoma had a higher asymptomatic rate (17.86% vs. 3.70%, P =.007) and a lower embolization rate (3.57% vs. 30.09%, P =.003) than left heart myxoma. The most common attachment site of right heart myxoma is the atrial septum. The mean operative duration and cardiopulmonary bypass time of right heart myxoma resection were 207.71 ± 53.40 minutes and 63.86 ± 29.73 minutes, respectively, with an in-hospital mortality rate of 3.57%. During the follow-up, 2 patients died of noncardiac causes. The overall 1-, 2-, and 5-year actuarial survival rates after right heart myxoma resection were 95.8%, 90.8%, and 84.7%, respectively. CONCLUSIONS: As a rare cardiac tumor, the clinical characteristics of right heart myxoma are different from typical left heart myxoma in some aspects, such as sex, asymptomatic rate, and embolization rate. Prompt surgical resection of right heart myxoma gives excellent early and midterm results.

RESUMO

INTRODUCTION: Understanding differences in perceived family functioning between pregnant women and their partners can protect and promote women's health. The purpose of this study was to examine consistency and differences in perceived family functioning within pregnant woman-partner dyads in China and explore correlates of effective family functioning. METHOD: From 2020 to 2021, 175 pregnant women and husband dyads (100% Han nationality, Mage = 30.3 [4.5] years) were recruited from the women's psychological clinic of Changsha Hospital for Maternal & Child Health Care using convenience sampling. We assessed family functioning and depression and anxiety symptoms. We examined consistency and differences in perceived family functioning between pregnant women and their husbands. RESULTS: Most pregnant women (76.6%) and husbands (71.4%) perceived their family functioning as effective. Pregnant women and their husbands shared poor consistency in family functioning, with an intraclass correlation of 0.25 and most weighted kappa coefficients of individual items < 0.2. Participants reporting effective family functioning had higher education levels and lower depression and anxiety scores. DISCUSSION: Most pregnant women and their partners perceived effective family functioning, but showed poor consistency. Higher education and milder symptoms of depression and anxiety were associated with effective family functioning both in pregnant women and their partners. For primary healthcare system workers, differences in perceptions of family functioning should be fully taken into account when conducting family based integrated care for pregnant women.

RESUMO

Background: Oxidative low-density lipoprotein (ox-LDL)-induced endothelial cell damage is a major risk factor for atherosclerosis and its related cardiovascular diseases. The G0/G1 switch gene 2 (G0S2) is a multifunctional protein which has been poorly studied in atherosclerosis. Methods: In this study, ox-LDL was utilized to construct a human aortic endothelial cell (HAEC) injury model. Results: It was found that ox-LDL impaired cell viability, augmented lactate dehydrogenase (LDH) release, and reduced G0S2 levels in HAECs in a dose-dependent manner. Further, G0S2 overexpression improved the viability and restrained apoptosis of HAECs treated by ox-LDL. Conversely, G0S2 depletion decreased the viability and aggravated apoptosis of HAECs treated by ox-LDL. At the molecular level, G0S2 overexpression significantly increased the secretion of superoxide dismutase (SOD), catalase (CAT), and glutathione peroxidase (GPH-Px), promoted intracellular reactive oxygen species (ROS) production and malondialdehyde (MDA) content in HAECs under either normal or ox-LDL conditions. Meanwhile, the ox-LDL-induced mitochondrial dysfunction, as demonstrated by decreased mitochondrial membrane potential, translocation of mitochondrial cytochrome c (Cyt-c) to the cytoplasm, and activation of caspase-3 and caspase-9, was significantly reversed by G0S2 overexpression. In addition, G0S2 overexpression promoted the activation of AMP-activated protein kinase (AMPK) and increased the expression of nuclear factor erythroid-2-related factor-2 (Nrf2), sirtuin 1 (SIRT1) and heme oxygenase 1 (HO-1) under normal and ox-LDL conditions. Conclusions: This study demonstrated that G0S2 protects against ox-LDL-induced vascular endothelial cell injury by regulating oxidative damage and mitochondrial homeostasis and may be a promising target for the treatment of atherosclerosis.
