Abstract
Silent information regulator factor 2-related enzyme 1 (Sirt1) is involved in the regulation of cell senescence, gene transcription, energy balance and oxidative stress. However, the effect of Sirt1 on atrial natriuretic factor (ANF) secretion, especially under hypoxic conditions is unclear. The present study aimed to investigate the effect of Sirt1, regulated by NADPH oxidase 4 (NOX4), on ANF secretion in isolated beating rat atria during hypoxia. ANF secretion was analyzed using radioimmunoassays and protein expression levels were determined by western blotting and immunofluorescence staining. Intra-atrial pressure was recorded using a physiograph. Hypoxia significantly upregulated Sirt1 and nuclear factor erythroid-2-related factor 2 (Nrf2) protein expression levels, together with significantly increased ANF secretion. Hypoxia-induced protein expression of Sirt1 was significantly blocked by a NOX4 inhibitor, GLX351322, and Nrf2 protein expression levels were significantly abolished using the Sirt1 inhibitor, EX527. Hypoxia also significantly elevated the protein expression levels of phosphorylated-Akt and sequestosome 1 and significantly downregulated Kelch-like ECH-associated protein 1 protein expression levels. These effects were significantly blocked by EX527, preventing hypoxia-induced Nrf2 expression. An Nrf2 inhibitor, ML385, significantly abolished the hypoxia-induced upregulation of activating transcription factor (ATF)3, ATF4, T cell factor (TCF)3 and TCF4/lymphoid enhancer factor 1 (LEF1) protein expression levels, and significantly attenuated hypoxia-induced ANF secretion. These results indicated that Sirt1 and Nrf2, regulated by NOX4, can potentially stimulate TCF3 and TCF4/LEF1 signaling via ATF3 and ATF4 activation, thereby potentially participating in the regulation of ANF secretion in beating rat atria during hypoxia. In conclusion, intervening with the Sirt1/Nrf2/ATF signaling pathway may be an effective strategy for resisting oxidative stress damage in the heart during hypoxia.

Abstract
BACKGROUND Hemorrhagic transformation (HT) is a common complication of acute ischemic stroke, often resulting from reperfusion therapy. Early prediction of HT can enable stroke neurologists to undertake measures to avoid clinical deterioration and make optimal treatment strategies. Moreover, the trend of extending the time window for reperfusion therapy (both for intravenous thrombolysis and endovascular treatment) further requires more precise detection of HT tendency. SUMMARY In this review, we summarized and discussed the neuroimaging markers of HT prediction of acute ischemic stroke patients, mainly focusing on neuroimaging markers of ischemic degree and neuroimaging markers of blood-brain barrier permeability. This review is aimed to provide a concise introduction of HT prediction and to elicit possibilities of future research combining advanced technology to improve the accessibility and accuracy of HT prediction under emergent clinical settings. Key Messages: Substantial studies have utilized neuroimaging, blood biomarkers, and clinical variables to predict HT occurrence. Although huge progress has been made, more individualized and precise HT prediction using simple and robust imaging predictors combining stroke onset time should be the future goal of development.

Abstract
BACKGROUND Current research on perinatal depression rarely pays attention to the continuity and volatility of depression symptoms over time, which is very important for the early prediction and prognostic evaluation of perinatal depression. This study investigated the trajectories of perinatal depression symptoms and aimed to explore the factors related to these trajectories. METHODS The study recruited 550 women during late pregnancy (32 ± 4 weeks of gestation) and followed them up 1 and 6 weeks postpartum. Depressive symptoms were measured using the Edinburgh Postnatal Depression Scale (EPDS). Latent growth mixture modelling (LGMM) was used to identify trajectories of depressive symptoms during pregnancy. RESULTS Two trajectories of perinatal depressive symptoms were identified: "decreasing" (n = 524, 95.3%) and "increasing" (n = 26, 4.7%). History of smoking, alcohol use and gestational hypertension increased the chance of belonging to the increasing trajectories, and a high level of social support was a protective factor for maintaining a decreasing trajectory. CONCLUSIONS This study identified two trajectories of perinatal depression and the factors associated with each trajectory. Paying attention to these factors and providing necessary psychological support services during pregnancy would effectively reduce the incidence of perinatal depression and improve patient prognosis.

Abstract
The rapidly changing treatment paradigm for patients with metastatic oncogene-driven lung cancer continues to evolve, and consequently our understanding of the landscape of resistance must also advance. MET amplification is an established and frequent driver of resistance in EGFR-mutant non-small-cell lung cancer (NSCLC). Recently, the combination of MET proto-oncogene (MET) and epidermal growth factor receptor (EGFR) tyrosine kinase inhibitors (TKIs) has shown promise in overcoming this molecularly defined resistance in clinical trials, and this combination strategy is being pursued in ongoing trials. Emerging data also demonstrate MET amplification as a resistance driver to TKI-treated ALK-, RET-, and ROS-1-fusion NSCLC, consistently at the range of 15%, while the resistance profiling data are maturing for other molecular targets. In this review, we discuss MET amplification as a driver of acquired resistance in well-defined molecular subsets of NSCLC, explore the biology behind this mechanism of resistance, and summarize the recently published clinical data, including the proposed combination strategies in the clinic achieving success in overcoming acquired MET amplification-dependent resistance. Understanding mechanisms of resistance in oncogene-driven lung cancer is crucial. MET amplification is a recurrent driver of resistance, across molecularly defined subsets of NSCLC. Overcoming this resistance in clinical trials, using combination strategies, is currently being pursued. We explore the biology behind this mechanism of resistance and summarize recent successes in the clinic.

Abstract
Background The stroke screening survey (SSS) is an essential strategy for stroke prevention. However, previous studies rarely discussed the effect of SSS on the acute phase treatment procedure for acute ischemic stroke (AIS) and the long-term prognosis outcomes. This study aims to investigate the effect of SSS on intravenous thrombolysis and long-term outcomes in AIS patients. Methods The stroke patients included were collected from Jiading Residences Community Health Records and Shanghai Stroke Service System database, from January 2017 to December 2019. Patients were divided into two groups, according to whether they have been screened before the event (onset and death). Demographic characteristics and treatment information of patients in the two groups were compared by the Mann-Whitney test and Chi-square test. The demographic differences between groups were adjusted with Propensity Score Matching (PSM) to evaluate the effect of SSS on door-to-needle time (DNT). The Kaplan-Meier survival curve with a log-rank test and multiple Cox regression model were used to evaluate the effect of SSS on long-term lifetime. Results A total of 1,236 patients with AIS were collected, including 468 (37.86%) female, 126 (10.19%) patients with intravenous thrombolysis, 241 (23.30%) patients died from all-cause mortality by January 8, 2020. A total of 124 (10.03%) patients have been screened before AIS onset, and 261 (21.17%) patients had undergone SSS after AIS onset. The baseline information indicated that patients with previous screening were older than the patients without at the time of onset [75 (70, 83) vs. 73 (65, 82), P=0.017], as well as more likely to have a history of hypertension (90.32% vs. 78.51%, P=0.002) and diabetes (50.00% vs. 25.81%, P<0.001). PSM results showed that patients with previous screening were associated with less severe onset situation [3 (1, 9) vs. 3 (1, 5), P=0.001] and shorter DNT [30 (24, 49) vs. 44 (31.5, 49), P=0.037] when compared to patients without. Additionally, patients with SSS had a lower hazard ratio of 0.567 (95% CI: 0.380–0.847, P=0.006) on all-cause mortality. Conclusions For AIS patients, the SSS is associated with less severe onset situation, shorter DNT, and longer long-term lifetime.

Abstract
Genistein, an isoflavonoid that can inhibit protein tyrosine kinase (PTK) phosphorylation, has been shown to play pivotal roles in the signal transduction pathways of hypoxic disorders. In this study, we established a rat model of isolated beating atrium and investigated the regulator role of genistein and its downstream signaling pathways in acute hypoxia-induced atrial natriuretic peptide (ANP) secretion. Radioimmunoassay was used to detect the ANP content in the atrial perfusates. Western blot analysis was used to determine the protein level of hypoxia-inducible factor 1α (HIF-1α), and GATA4 in the atrial tissue. The results showed that acute hypoxia substantially promoted ANP secretion, whereas this effect was partly attenuated by the PTKs inhibitor genistein (3 μM). By Western blotting analysis, we found that hypoxia-induced increase in phosphorylation of Akt and transcriptional factors, including HIF-1α, were also reversed by genistein. The perfused HIF-1α inhibitors rotenone (0.5 μM) or CAY10585 (10 μM) plus genistein significantly abolished the enhanced ANP section induced by hypoxia. Additionally, the perfused PI3K/Akt agonist insulin-like growth factor 1 (30 μM) also abolished ANP secretion induced by genistein and inhibited expression of HIF-1α. In summary, our data suggested that acute hypoxia markedly increased ANP secretion by PTKs through the phosphoinositide-3 kinase (PI3K)/HIF-1α dependent pathway.

Abstract
Mindfulness-based interventions such as meditation have increasingly been utilized for the treatment of psychological disorders and have been shown to be effective in the treatment of depression and relapse prevention. However, it remains largely unclear the neural mechanism of the therapeutic effects of meditation among depressed individuals. In this study, we investigated how body-mind relaxation meditation (BMRM) can modulate the thalamocortical functional connectivity (FC) in major depressive disorder patients and healthy controls. In the present study, we recruited 21 medication-naive adolescents with major depressive disorder (MDDs) and 24 matched healthy controls (HCs). We designed an audio recording to induce body-mind relaxation meditation. Resting-state fMRI (rs-fMRI) scans were collected before and after the BMRM intervention in both groups. The thalamus subregions were defined according to the Human Brainnetome Atlas, and functional connectivity (FC) was measured and compared to find brain regions that were affected by the BMRM intervention. Before the BMRM intervention, MDDs showed reduced FC of the bilateral precuneus/post cingulate cortex with the left posterior parietal thalamus and left caudal temporal thalamus, as well as an increased FC of the left occipital thalamus with the left medial frontal cortex. Moreover, aberrant FCs in MDDs at baseline were normalized following the BMRM intervention. After the BMRM intervention, both MDDs and HCs showed decreased FC between the left rostral temporal thalamus and the left inferior occipital. Given the small sample used in this study, future studies are warranted to evaluate the generalizability of these findings. Our findings suggest that BMRM is associated with changes in thalamocortical functional connectivity in MDDs. BMRM may act by strengthening connections between the thalamus and the default mode network, which are involved in a variety of high-level functioning, such as attention and self-related processes.

Abstract
The association between baseline perfusion measures and clinical outcomes in patients with acute small subcortical infarcts (SSIs) has not been studied in detail. Post-processed acute perfusion CT and follow-up diffusion-weighted imaging of 71 patients with SSIs were accurately co-registered. Relative perfusion values were calculated from the perfusion values of the infarct lesion divided by those of the mirrored contralateral area. The association between perfusion measures with clinical outcomes and the interaction with intravenous thrombolysis were studied. Additionally, the perfusion measures for patients having perfusion CT before and after thrombolysis were compared. Higher contralateral hemispheric cerebral blood flow (CBF) was the only independent predictor of an excellent clinical outcome (modified Rankin Scale of 0-1) at 3 months (OR = 1.3, 95% CI 1.1-1.4, P = 0.001) amongst all the perfusion parameters, and had a significant interaction with thrombolysis (P = 0.04). Patients who had perfusion CT after thrombolysis demonstrated a better perfusion profile (relative CBF ≥1) than those who had perfusion CT before thrombolysis (After:45.5%, Before:21.1%, P = 0.03). This study implies that for patients with SSIs, hemispheric CBF is a predictor of clinical outcome and has an influence on the effect of intravenous thrombolysis.

Abstract
Aims The aim of the study was to develop a simple and objective score using clinical variables and quantified perfusion measures to identify embolic stroke with large vessel occlusions. Methods Eligible patients from five centers participating in the International Stroke Perfusion Imaging Registry were included in this study. Patients were split into a derivation cohort (n = 213) and a validation cohort (n = 116). A score was developed according to the coefficients of independent predictors of embolic stroke from stepwise logistic regression model in the derivation cohort. The performance of the score was validated by assessing its discrimination and calibration. Results The independent predictors of embolic stroke made up the Chinese Embolic Stroke Score (CHESS). There were: history of atrial fibrillation (3 points), non‐hypertension history (2 points), and delay time>6 s volume/delay time>3 s volume on perfusion imaging ≥0.23 (2 points). The AUC of CHESS in the derivation cohort and validation cohort were 0.87 and 0.79, respectively. Patients with a CHESS of 0 could be identified as low‐risk of embolic stroke, with a CHESS of 2–4 could be identified as medium‐risk and with a CHESS of 5–7 could be regarded as high‐risk. The observed rate of embolic stroke of each risk group was well‐calibrated with the predicted rate. Conclusion CHESS could reliably and independently identify embolic stroke as the cause of large vessel occlusion.

Abstract
BACKGROUND Interleukin (IL)-18 is produced mainly in the heart, and can be associated to the development of cardiac hypertrophy that leads to cardiac dysfunction. However, the effects of hypoxia on IL-18 expression and atrial natriuretic factor (ANF) secretion remain largely unknown. AIM To assess the effect of hypoxia on IL-18 production and its role in ANF secretion by using an isolated perfused beating rat atrial model. METHODS The level of ANF in the perfusates was determined by radioimmunoassay, and the protein levels of Src, IL-18 and its receptors (IL-18-Rα and IL-18-Rβ), Rho guanine nucleotide exchange factor (RhoGEF) and RhoA, activating transcription factor 3 (ATF3), T cell factor (TCF) 3 and 4, and lymphoid enhancer factor (LEF) 1 in atrial tissue samples were detected by Western blotting. RESULTS Hypoxia significantly upregulated the expression of non-receptor tyrosine kinase Src, and this effect was blocked by endothelin-1 receptor type A (BQ123) and type B (BQ788) antagonists. Hypoxia also enhanced the expression of RhoGEF and RhoA concomitantly with the upregulation of IL-18, IL-18-Rα and IL-18-Rβ. The hypoxia-induced RhoGEF and RhoA were abolished by Src inhibitor 1 (SrcI), and the protein levels of IL-18 and its two receptors were also blocked by SrcI. Moreover, the hypoxia-induced expression levels of ATF3, TCF3, TCF4 and LEF1 were repealed by IL-18 binding protein, and the hypoxia-promoted secretion of ANF was also obviously attenuated by this binding protein. CONCLUSIONS These findings imply that Src-IL-18 signaling is involved in the release of ANF in hypoxic beating rat atria.

Abstract
A systematic investigation was conducted onthe co-pyrolysisof Fe3O4and PVC mixtures in temperatures as high as 1373 K upon the development of PVC recycling technology that mitigates chlorine emission. Central to our investigation, PVC decomposition plays the leading role in the co-pyrolysis of Fe3O4and PVC mixtures following a two-stage pattern bifurcated at a temperature of 673 K. In Stage 1, at temperatures 673 K and lower, Fe3O4is chlorinated by chlorine from PVC, resulting in FeCl2. The composition of the final solid residue of Stage 1,conjugated polyene, FeCl2and Fe3O4/Fe2O3, depends on the initial Fe3O4content in the mixture. When the temperature is increased to be higher than 673 K, decomposition of conjugated polyene occurs simultaneously with the stepwise reduction of Fe3O4/Fe2O3: Fe2O3 → Fe3O4 → FeO → Fe. However, in mixtures containing Fe3O4that is less than 39.6% of the mass, Fe3O4can coexist with Fe; therefore, the FeO formation step is skipped. Most FeCl2escapes from the reaction system as vapor, showing the necessity of removing FeCl2at the end of Stage 1 to avoid harmful substance emission. The presence of Fe3O4can significantly suppress gaseous emissions, especially HCl originating from PVC decomposition. There was only 0.6% HCl by mass (2.4% PVC base by mass) released when co-pyrolyzing the PVC + 75% Fe3O4mixture due to the complete consumption of PVC and its decomposition products by Fe3O4. After separating FeCl2,which is a valuable chemical feedstock, by water-leaching the solid residue obtained at 673 K, the filtered residue,which is a mixture of Fe3O4/Fe2O3and polyene, was confirmedto be suitable for iron-making. The results clearly show the possibility of developing a PVC recycling technology with mitigated chlorine emissions by manipulating the amount of Fe3O4added.

Abstract
Objective:
To develop a simple and objective score using clinical variables and quantified perfusion measures to identify embolic stroke with large vessel occlusions.
Methods:
Eligible patients from the Chinese centers participating in the International Stroke Perfusion Imaging Registry were included in this study. Patients were split into a derivation cohort (n=213) and a validation cohort (n=116). A score was developed according to the coefficients of independent predictors of embolic stroke from stepwise logistic regression model in the derivation cohort. The performance of the score was validated by assessing its discrimination and calibration. Additionally, a comparison between the area under curve (AUC) of history of atrial fibrillation (AF) alone and history of AF plus the score was also conducted.
Results:
The independent predictors of embolic stroke made up the Chinese Embolic Stroke Score (CHESS). There were: age (≥64 years, 1 point), non-smoking history (1 point), non-hypertension history (1 point) , baseline NIH Stroke Scale (≥14, 1 point) and delay time>6s volume/delay time>3s volume on perfusion imaging (≥0.23, 2 points). The AUC of CHESS in the derivation cohort and validation cohort were 0.80 and 0.72 respectively. Calibration tests indicated high agreement between predicted and observed probabilities. The AUC of AF-plus-CHESS compared to history of AF alone was significant (derivation cohort P<0.001; validation cohort P=0.01).
Conclusions:
In a Chinese population, CHESS reliably and independently identified embolic stroke as the cause of large vessel occlusion.

THE KOREAN JOURNAL OF PHYSIOLOGY & PHARMACOLOGY : OFFICIAL JOURNAL OF THE KOREAN PHYSIOLOGICAL SOCIETY AND THE KOREAN SOCIETY OF PHARMACOLOGY 2021; 25:159-166. [PMID: 33602886 PMCID: PMC7893495 DOI: 10.4196/kjpp.2021.25.2.159] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 09/11/2020] [Revised: 12/24/2020] [Accepted: 12/29/2020] [Indexed: 01/11/2023]
Abstract
Nicotinamide adenine dinucleotide phosphate oxidases (NOXs) are the major enzymatic source of reactive oxygen species (ROS). NOX2 and NOX4 are expressed in the heart but its role in hypoxia-induced atrial natriuretic peptide (ANP) secretion is unclear. This study investigated the effect of NOX on ANP secretion induced by hypoxia in isolated beating rat atria. The results showed that hypoxia significantly upregulated NOX4 but not NOX2 expression, which was completely abolished by endothelin-1 (ET-1) type A and B receptor antagonists BQ123 (0.3 µM) and BQ788 (0.3 µM). ET-1-upregulated NOX4 expression was also blocked by antagonists of secreted phospholipase A2 (sPLA2; varespladib, 5.0 µM) and cytosolic PLA2 (cPLA2; CAY10650, 120.0 nM), and ET-1-induced cPLA2 expression was inhibited by varespladib under normoxia. Moreover, hypoxia-increased ANP secretion was evidently attenuated by the NOX4 antagonist GLX351322 (35.0 µM) and inhibitor of ROS N-Acetyl-D-cysteine (NAC, 15.0 mM), and hypoxia-increased production of ROS was blocked by GLX351322. In addition, hypoxia markedly upregulated Src expression, which was blocked by ET receptors, NOX4, and ROS antagonists. ET-1-increased Src expression was also inhibited by NAC under normoxia. Furthermore, hypoxia-activated extracellular signal-regulated kinase 1/2 (ERK1/2) and protein kinase B (Akt) were completely abolished by Src inhibitor 1 (1.0 µM), and hypoxia-increased GATA4 was inhibited by the ERK1/2 and Akt antagonists PD98059 (10.0 µM) and LY294002 (10.0 µM), respectively. However, hypoxia-induced ANP secretion was substantially inhibited by Src inhibitor. These results indicate that NOX4/Src modulated by ET-1 regulates ANP secretion by activating ERK1/2 and Akt/GATA4 signaling in isolated beating rat hypoxic atria.

Abstract
BACKGROUND The Low Resistance Thought Induction Psychotherapy (TIP) is a comprehensive psychological treatment which could improve the clinical symptoms of major depressive disorder (MDD). However, the neural mechanisms for TIP treating MDD still remain unclear. This study aimed to investigate the topology of intrinsic connectivity network and the therapeutic effects of TIP in MDD on these topological properties. METHODS Longitudinal study was conducted in 20 first-episode, treatment-naive MDD patients at baseline and after 6 weeks (12 sessions) of TIP treatment based on resting-state functional magnetic resonance image (rsfMRI) in conjunction with graph theoretical analysis. We constructed functional connectivity matrices and extracted the attribute features of the small-world networks in both MDD and age-, education level-, and gender-matched healthy controls (HCs). The global and local small-world network properties were explored and compared between MDD at baseline and HCs. The therapeutic effect of TIP was examined by comparing alterations in global and local network properties between MDD at baseline and after treatment. RESULTS At baseline, MDD showed altered small-worldness and aberrant nodal properties in the frontolimbic circuit particularly in the orbital frontal gyrus, insula, precuneus and middle cingulate gyrus as compared with HCs. Following 6 weeks treatment, the abnormalities in the small-worldness and the nodal metrics were modulated, which were accompanied by a significant improvement in the clinical symptoms. CONCLUSIONS Our findings contributed to the understanding of the abnormal topological patterns in the frontolimbic systems in MDD and implicated that these disruptions may be modified by TIP treatment.

Abstract
Objective: To investigate the clinical manifestations, treatments and prognosis of subacute arsenic poisoning. Methods: In January 2020, a retrospective analysis was carried out on 11 patients hospitalized with subacute arsenic poisoning caused by arsenic contaminated drinking water. We observed manifestations, treatments and prognosis. Results: The main clinical presentations of subacute arsenic poisoningin were gastroenteritis in early phase, some of them had other organ damage, such as skin, blood, liver, kidney, cardiovascular and so on. The later phase was mainly peripheral nervous system damage. The treatment was mainly to chelate arsenic, protect target organs and treat toxic peripheral neuropathy. Most were significantly recoveried, but the recovery of severe toxic peripheral neuropathy was tardy. Conclusion: Acute gastroenteritis is the mainly early manifestation of subacute arsenic poisoning caused by digestive tract, and toxic peripheral neuropathy in the later phase. The prognosis is good, but the recovery of severe toxic peripheral neuropathy is tardy.

INTERNATIONAL JOURNAL OF ENVIRONMENTAL RESEARCH AND PUBLIC HEALTH 2020; 17:ijerph17238792. [PMID: 33256179 PMCID: PMC7729895 DOI: 10.3390/ijerph17238792] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Download PDF] [Subscribe] [Scholar Register] [Received: 10/29/2020] [Revised: 11/24/2020] [Accepted: 11/25/2020] [Indexed: 12/02/2022]
Abstract
(1) Objective: To assess the reliability and validity of the simplified Chinese version of the brief Diabetes Quality of Life (DQoL) questionnaire in measuring health-related quality of life (HRQoL) in Chinese type 2 diabetes (T2D) patients. (2) Methods: A cross-sectional validation study including 277 patients was conducted at a tertiary hospital in Shanghai, China during April–May, 2018. The English brief DQoL was forward and back-translated into simplified Chinese. The expert interview, exploratory factor analysis (EFA), and Spearman correlation with the 5-level version of EuroQoL-5 (EQ-5D-5L) were employed to establish its validity. The internal reliability was assessed by Cronbach’s alpha. Participants were also stratified into subgroups to evaluate if the Chinese brief DQoL had more test effectiveness in a specific subpopulation. (3) Results: No items were removed from the original English brief DQoL based on the results of factor analysis and expert interview. The Spearman coefficient revealed a low-moderate inverse correlation between DQoL and EQ-5D-5L index and visual analogue scale (VAS), respectively (ρ1 = −0.364, p < 0.0001; ρ2 = −0.514, p < 0.0001). The Cronbach’s alpha coefficient of the final scale was 0.731. (4) Conclusions: The simplified Chinese version of the brief DQoL questionnaire showed reasonable reliability and validity, suggesting its potential appropriateness for evaluating quality of life in Chinese T2D patients. More future efforts should be made to generalize the application of the findings.
