Applying to a nursing home is a way to maintain control of life—Experiences from Swedish nursing home applicants
Authors: Spang Lisa , Holmefur Marie , Hermansson Liselotte , Lidström Holmqvist Kajsa
Published: July 2022

Background

Swedish social policy enables ageing in place with support from home‐based care services despite high age and/or declining health.

Aim

This study aims to describe the daily life experiences behind the decision to apply for a nursing home placement in older adults ageing in place.

Materials and Methods

A qualitative design was chosen, and 11 semi‐structured interviews were conducted and analysed using inductive qualitative content analysis.

Results

The participants described a feeling of dependence in which they had to ignore their personal privacy when receiving home‐based care. They reached a turning point when ageing in place was, for several reasons, no longer considered an acceptable option. This influenced their choice to apply to a nursing home where they expected that they could maintain control over their lives.

Discussion and Conclusion

The results indicate that when enhancing ageing in place it is important to enable older adults to receive support to maintain autonomy in daily activities and to have the opportunity to age in the right place.
Immune surveillance in glioblastoma: Role of the NKG2D system and novel cell‐based therapeutic approaches
Authors: Chitadze Guranda , Kabelitz Dieter
Published: July 2022

Glioblastoma, formerly known as glioblastoma multiforme (GBM), is the most frequent and most aggressive brain tumour in adults. The brain is an immunopriviledged organ, and the blood‐brain barrier shields the brain from immune surveillance. In this review, we discuss the composition of the immunosuppressive tumour micromilieu and potential immune escape mechanisms in GBM. In this respect, we focus on the role of the NKG2D receptor/ligand system. NKG2D ligands are frequently expressed on GBM tumour cells and can activate NKG2D‐expressing killer cells including NK cells and γδ T cells. Soluble NKG2D ligands, however, contribute to tumour escape from immunological attack. We also discuss the current immunotherapeutic strategies to improve the survival of GBM patients. Such approaches include the modulation of the NKG2D receptor/ligand system, the application of checkpoint inhibitors, the adoptive transfer of ex vivo expanded and/or modified immune cells or the application of antibodies and antibody constructs to target cytotoxic effector cells in vivo. In view of the multitude of pursued strategies, there is hope for improved overall survival of GBM patients in the future.
Understanding interpersonal guilt: Associations with attachment, altruism, and personality pathology
Authors: Leonardi Jessica , Gazzillo Francesco , Gorman Bernard S. , Kealy David
Published: July 2022

The aim of this article is to empirically investigate the relationships among interpersonal guilt, as conceived within control‐mastery theory (CMT), and attachment, altruism, and personality pathology in an English‐speaking sample. An online sample of 393 participants was recruited to complete the Interpersonal Guilt Rating Scale self‐report version‐15 (IGRS‐15s), together with other empirically validated measures for the assessment of attachment, altruism, and personality pathology. On the basis of previous studies conducted in Italian‐speaking samples, we hypothesized that survivor guilt, separation/disloyalty guilt, and omnipotent responsibility guilt would be associated with attachment anxiety and avoidance, altruism, and personality pathology; self‐hate was hypothesized to be associated only with attachment anxiety and avoidance and personality pathology. Analyses examined bivariate associations as well as the network of partial correlations among variables. The results largely confirmed hypothesized associations, with self‐hate evincing the strongest unique association with personality dysfunction. Findings provide a basis for further research regarding interpersonal guilt and personality and relational functioning, with potential implications for clinical conceptualizations of the role of guilt in psychopathology.
Likeminded? Congruence Between Political Elites and their Voters Regarding Policy Choices inSwiss‐EURelations
Authors: Lauener Lukas
Published: July 2022

Swiss‐EU relations not only rank among the most important political problems for citizens but are also the subject of repeated political contestation. Using data from the 2019 Swiss Election Study (Selects), this article examines the extent to which the opinions of political elites and voters coincide on four European integration issues: 1) the trade‐off between maintaining the bilateral agreements and limiting immigration, 2) the cohesion billion, 3) the trade‐off between the institutional framework agreement and the accompanying measures, and 4) EU membership. The results show that, overall, candidates represent voters extremely well with regard topositions, i.e., both groups are “on the same side”. However, candidates are generally more EU‐integrationist and hold more extreme opinions than voters. Moreover, this article investigates how well candidates represent thevarietyof voter opinions and finds that – contrary to previous research – there is no systematic difference between centrist and pole parties.

Narrow‐leafed lupin (NLL; Lupinus angustifolius) is a key rotational crop for sustainable farming systems, whose grain is high in protein content. It is a gluten‐free, non‐genetically modified, alternative protein source to soybean (Glycine max) and as such has gained interest as a human food ingredient. Here, we present a chromosome‐length reference genome for the species and a pan‐genome assembly comprising 55 NLL lines, including Australian and European cultivars, breeding lines and wild accessions. We present the core and variable genes for the species and report on the absence of essential mycorrhizal associated genes. The genome and pan‐genomes of NLL and its close relative white lupin (Lupinus albus) are compared. Furthermore, we provide additional evidence supporting LaRAP2‐7 as the key alkaloid regulatory gene for NLL and demonstrate the NLL genome is underrepresented in classical NLR disease resistance genes compared to other sequenced legume species. The NLL genomic resources generated here coupled with previously generated RNA sequencing datasets provide new opportunities to fast‐track lupin crop improvement.
Family–level phylogeny of infraorder Systellognatha (Insecta: Plecoptera) inferred from mitochondrial genomes
Authors: Wang Ying , Cao Jinjun , Murányi Dávid , Guo Xuan , Guo Caiyue , Li Weihai
Published: July 2022

Systellognatha is a monophyletic group within stoneflies containing seven families in two superfamilies. However, the family–level phylogeny within Systellognatha is largely unresolved, with some controversial hypotheses generated by molecular data. In this study, we sequenced one complete and three nearly complete mitochondrial genomes (mitogenomes) representing three systellognathan families (including one newly described family), to recover the phylogeny of all seven extant systellognathan families. We tested the effect of heterogeneous sequence divergence within mitogenome sequences on phylogenetic reconstruction. To study incongruent topologies supported by different datasets, we also utilized four–cluster likelihood mapping to elucidate these phylogenetic questions. We found a low degree of compositional heterogeneity in systellognathan mitogenomes. Our results showed that phylogenetic analyses with various datasets under site–homogeneous models failed to recover the Perloidea and Pteronarcyoidea as monophyletic groups. However, Bayesian inference with a site–heterogeneous model (CAT + GTR) recovered Perloidea as monophyletic. Our results confirm a sister–group relationship between Chloroperlidae and Perlodidae. Despite all phylogenetic analyses failed to recover the Pteronarcyoidea as monophyletic, the analyses with site–heterogeneous model based on PCG12, PCG12R and PCGR datasets reconstructed the same relationships among Pteronarcyidae, Peltoperlidae, Styloperlidae and Perloidea. Our study shows the power of the site–heterogeneous models in resolving phylogeny within Systellognatha and provides a new insight into the phylogeny of this group.
Giant deep submarine depressions: A combined dissolution-mechanical process along carbonate margins

Published: July 2022

Submarine depressions are common features on the eastern Bahamian seafloor but the genesis of the deepest ones (>4000 m in water depth) is not well understood. We conducted a morphometric analysis and compared them to a worldwide database of rounded depressions, whatever their genesis is. The deep Bahamian depressions are large elongated structures, among the largest on Earth, with a width greater than 1000 m and a depth sometimes greater than 200 m. They extend at the toe of the Blake Bahama Escarpment (BBE), one of the tallest escarpments on Earth. Some of them align parallel to the BBE. Other depressions align along large submarine canyon axes. When aligned along canyon axes, the depressions closest to the canyon head are flanked by a topographic high interpreted as a slope-break deposit, i.e., sediment deposited after flow expansion following a hydraulic jump. Turbidity currents in the carbonate canyon system are not permanent processes, but are rather triggered during sea-level highstands when the carbonate platform is flooded. In addition, some depressions are not located in canyon axes. Consequently, the size and location of the depressions are not likely explained by a simple plunge pool mechanical erosion. Rather, our data suggest that all depressions could be initiated by giant karstic dissolution structures (dolines or sinkholes). Under interpretation, those located in canyon axes are sporadically refreshed by carbonate-laden turbidity currents. The height of the outsized chutes marking the crossing of the BBE by the canyon mouth generates a hydraulic jump allowing sediment deposition toward the bottom of the depression. Large depressions observed at this location in the Bahamas were the result of an initial dissolution phase related to retreat of the BBE and the more recent sediment-laden flow activity. The depressions orientated along canyon axes facilitated the regressive erosion that formed the canyons. At present, the depressions located at canyon mouths act as regular plunge pools.
The Study of Jarosite Waste Used for Suspension Electrolysis in Aqueous NaOH Electrolyte
Authors: Qin Bo , Haarberg Geir Martin
Published: July 2022

Jarosite waste is normally generated from the purification process of zinc production. It contains many valuable elements such as zinc, lead, and especially iron. In the present study, jarosite waste was treated through thermal analysis and washing processes to concentrate hematite. An electrolysis process was used to reduce iron from the hematite in order to seek a new way to recycle the value of the resource. The electrochemical behavior of hematite in jarosite waste was studied by cyclic voltammetry at 100 °C in a 50 wt% NaOH aqueous solution. Constant cell voltage electrolysis was performed at 1.6 V by using electrolysis of a suspension of purified jarosite. Iron was found to deposit on a silver cathode during electrolysis. The sample was collected and analyzed by XRD.

Published: July 2022

In this paper, a long-term durability test for 3910 h is carried out on a low Pt-loading fuel cell stack by simulating the dynamic driving cycles. The performance of a specific membrane electrode assembly (MEA) in the stack before and after the test is analyzed, revealing the high voltage decay rate of the appliance. Various electrochemical and physical characterization techniques are used to analyze the degradation mechanism of the MEA via region-based segmentation technique. The results show that the degradation of MEA performance is mainly due to the agglomeration and loss of Pt nanoparticles in the cathode catalyst. In particular, the growth of catalyst particles occurs at the inlet and outlet of the cathode. A high loss rate of Pt particles at the cathode inlet causes their aggregation at the boundary between the catalyst layer and the membrane where the loss of Pt is initiated. Finally, the migration of the unsupported Pt particles occurs due to the gravity toward the underlying cathode micro porous layer. This study had important implications for promoting the development and commercial application of cost-efficient and long-life MEAs.

Authors: Marani R. , Perri A. G.
Published: July 2022

In this paper we review a procedure to design and characterize logic gates based on CNTFET and CMOS technology. For the first technology we use a CNTFET model, already proposed by us, while for the second one we use the BSIM4 model of the Advanced Design System (ADS) library. In particular we consider NAND and NOT gates at different supply voltages and frequencies, for both technologies. The optimal results, obtained using the simulator ADS, are at 0.5 V and 50 GHz for CNTFET, while for CMOS technology at 3 V and 200 MHz. Moreover we quantitatively show the comparison between the two considered technologies in term of delay and power delay product (PDP).

Published: July 2022

According to the sixth edition of China’s “New Coronavirus Diagnosis and Treatment Plan (NCDTP),” ReDuNing injection (RDN) was firstly introduced to treat severe and critical COVID-19, whereas its combination with broad-spectrum antibiotics was suggested to take with extreme caution and full reasons. Therefore, we aim to describe the pharmacokinetics of seven active phytochemicals and semiquantification of nine relevant metabolites in ReDuNing injection (RDN) after combining with cefuroxime sodium (CNa) for injection in rat plasma. Male Sprague–Dawley rats were randomly assigned to six groups, and they were intravenously administered, respectively, with different prescriptions of RDN (2 mL/kg) and CNa (225 mg/kg). At different time points (0.03, 0.08, 0.17, 0.24, 0.33, 0.50, 0.67, 1, and 6 h) after administration, the drug concentrations of iridoids glycosides, organic acids, and metabolites in rat plasma were determined using ultrahigh-pressure liquid chromatography coupled with linear ion rap-orbitrap tandem mass spectrometry (UHPLC–LTQ–Orbitrap–MS), and main pharmacokinetic parameters were estimated by noncompartment model. The results showed that there were differences in pharmacokinetic parameters, AUC(0-t), T1/2, Cmax, CL of iridoids glycosides, and organic acids, after the intravenous administration of the different combinations of RDN and CNa. Moreover, different combinations of the injections also resulted in different curves of relative changes of each metabolite. The obtained results suggested that RDN and CNa existed pharmacokinetic drug–herb interactions in rats. The findings not only lay the foundation for evaluating the safety of RDN injection combined with CNa but also make contributions to clinically applying RDN injection combined with CNa, which works potentially against severe forms of COVID-19.
Digital Inclusive Finance Data Mining and Model-Driven Analysis of the Impact of Urban-Rural Income Gap
Authors: Peng Chenyang
Published: July 2022

Digital inclusive finance, rural human capital, and agricultural green total factor productivity are simultaneously incorporated into the framework of urban-rural income gap analysis. Based on digital inclusive finance indices from several provincial panel data in China, a systematic generalized moment estimation method is used to the moderating effect of rural human capital and the mediating role of agricultural green total factor productivity. Annual time series data of foreign trade indicators and urban-rural income gap indicators are estimated by building a state-space model and applying Kalman filter to investigate the effects of these factors on the urban-rural income gap. The results show that the impact of urban-rural fixed asset investment ratio and foreign trade indicator on the urban-rural income gap in China tends to increase gradually, while the impact of rural financial development indicator is decreasing but still positive. The study finds that the development of digital inclusive finance significantly contributes to the reduction of the income gap between urban and rural residents; the breadth of coverage of digital inclusive finance and the degree of digitalization help to suppress the widening of the income gap between urban and rural residents; and rural health-based human capital, education and training-based human capital, and migration-based human capital not only have a convergence effect on the income gap between urban and rural residents themselves.
Damage Mechanism of Asphalt Concrete Pavement under Different Immersion Environments
Authors: Jiang Zaiyang
Published: July 2022

With the construction of road infrastructure in China, the rapid development of expressways has provided great convenience for human travel and cargo transportation. Asphalt concrete pavement is widely used in highway construction because of its characteristics of good flatness, high strength, and convenient maintenance. But the water damage of asphalt concrete pavement is the main factor affecting the stability of highway subgrade and flatness of pavement, as well as the main cause of deformation and collapse of pavement. In view of the water damage problem of asphalt concrete pavement, this paper investigates the overall condition and water damage situation of asphalt concrete pavement with different immersed states and carries out indoor simulation test of asphalt concrete samples without water, dry and wet cycle, and saturated water. The quality, loss rate and Marshall stability of the samples under different times of cyclic rolling were obtained through the statistics of cyclic rolling pressure of the samples. The influencing factors of water loss, water resistance and failure forms of highway under different impregnation environments were analyzed, and the prevention measures of water loss of asphalt concrete were put forward. The test results show that the mass loss rate of the sample is water-free, dry-wet cycle, and water-saturated, and the Marshall stability of the sample is water-free, dry-wet cycle, and water-saturated from high to low. Under the action of rolling and friction forces, the fine aggregates in the asphalt concrete are worn off, which leads to the expansion of cracks on the surface of the sample and the formation of fissure network. Small holes appear on the surface of water-saturated sample, and the coarse aggregate is broken and disintegrated under pore water pressure. Traffic flow (cyclic rolling times) and immersion state have become the main factors of asphalt concrete pavement failure. This study has specific and important theoretical guiding significance for reducing and preventing water damage of asphalt concrete pavement of expressway, delaying road service life, and enhancing road safety.
Structures under Synergetic Effects of Combined Blast and Impact Loads: A State‐of‐the‐Art Review
Authors: Abebe Solomon , Alemu Mohammed Tesfaye
Published: July 2022

When the effect of combined blast induced shock wave and fragment penetration impact load is sufficiently large enough to induce severe damage in structures compared to individual actions of only‐blast and only‐impact load, this scenario is called synergetic effect of simultaneous actions. The combined nature of those dual actions aggravates damage and collapses of structures. This paper presented the state‐of‐the‐art review on effect of different parameters, dynamic responses, failure types, and damage mitigation techniques for structures prone to combined actions of blast induced shock wave and fragment impact loads based on findings of experimental, numerical, and analytical research works conducted in previous literature.
Multi-Objective Optimal Power Flow including Wind and Solar Generation Uncertainty Using New Hybrid Evolutionary Algorithm with Efficient Constraint Handling Method
Authors: Avvari Ravi Kumar , D. M. Vinod Kumar
Published: July 2022

A new hybrid decomposition-based multiobjective evolutionary algorithm is proposed for optimal power flow (OPF) including wind and solar generation uncertainty. This study recommends a novel constraint-handling method, which adaptively adds the penalty function and eliminates the parameter dependency on penalty function evaluation. The summation-based sorting and improved diversified selection methods are utilized to enhance the diversity of multiobjective optimization algorithms. The OPF problem is modeled as a multiobjective optimization problem with four objectives such as minimizing (i) total fuel cost (TC) including the cost of renewable energy source (RES), (ii) total emission (TE), (iii) active power loss (APL), and (iv) voltage magnitude deviation (VMD). The impact of RESs such as wind and solar energy sources on integration is considered in optimal power flow cost analysis. The costs of RESs are considered in the OPF problem to minimize the overall cost so that the impact of intermittence and uncertainty of renewable sources is studied in terms of cost and operation wise. The uncertainty of wind and solar energy sources is described using probability distribution functions (PDFs) such as Weibull and lognormal distributions. The efficiency of the algorithm is tested on IEEE 30-, IEEE 57-, and IEEE 118-bus systems for all possible conditions of renewable sources using Monte Carlo simulations.

Published: July 2022

In this paper, the long short-term memory with dense neural network (LSTM-DNN) is first introduced to calculate marine drifting trajectory. Based on the Internet of Things technology and the LSTM-DNN algorithm, the marine drifting trajectory model is established. In this model, the information such as wind field, temperature field, ocean current motion field, and target attributes are included, and the influences of the above information on the trajectory model are studied in detail. In order to verify the proposed model, the marine experiments are carried out in the end. The results show that the predicted trajectory data matches well with the experimental trajectory data. By introducing DNN into the algorithm, computational accuracy of drifting trajectory can be significantly improved compared with the conventional LSTM-based prediction model. A detailed comparison of the two algorithms has also been given in the paper. The proposed remote sensing of marine drifting trajectory model can provide a high accurate trajectory prediction and will lead an important guidance in the marine search and rescue work.
Assessment of Trimetazidine Treatment in Acute Myocardial Infarction Patients Undergoing Percutaneous Coronary Intervention
Authors: Tang Xiuying , Gong Jie
Published: July 2022

Aims. Trimetazidine (TMZ) is effective at improving clinical outcomes in chronic heart failure and stable coronary artery disease patients. However, no single study has comprehensively evaluated the efficacy of TMZ in acute myocardial infarction (AMI) patients undergoing percutaneous coronary intervention (PCI). Methods. We enrolled 401 Chinese patients. All patients received the same drug prescription except for TMZ. In blinded fashion, patients were randomized to either a control or an experimental group in which 60 mg TMZ was provided at admission and then at 20 mg three times a day thereafter. At 2 and/or 6 days, we evaluated creatine kinase (CK and CK-MB), cardiac troponin I (cTnI), C-reaction protein (CRP), serum tumor necrosis factor (TNF-α), serum creatinine (Cr), serum urea, glucose, glutamic pyruvic transaminase (ALT), and glutamic oxaloacetic transaminase (AST). Additionally, by echocardiography, we assessed left ventricular ejection fraction (LVEF), left ventricular end-diastolic dimension (LVEDD), and cardiac output (CO). Results. CK and CKMB, which were recorded on the second day in the hospital (each

p
=

), and cTNI, which was recorded on the sixth day in the hospital (

p
=
0.003

), were reduced with TMZ treatment compared to control. In addition, ALT and AST (

) were significantly lower in the study group than in the control group. Furthermore, LVEF after 10–14 days and 6 months after discharge (

p

0.039

and

p
=
0.047

, respectively) was increased with TMZ treatment. The effects of TMZ on CRP, TNF-α, Cr, urea, LVEDD, and CO were not significant (all

). Conclusions. For AMI patients undergoing PCI, TMZ reduced circulating biomarkers of myocardial infarction, reduced values of ALT, AST, and glucose, and improved cardiac function compared with the control group.
Eosinophilic Myocarditis: An Often-Overlooked Diagnosis in Patients Presenting with Heart Failure
Authors: Cho Young Min , Asreb Abdullah , Mahmood Riaz , Moaz Ahmad , Egolum Ugochukwu
Published: July 2022

Introduction. Hypereosinophilic syndrome (HES) is a rare disease characterized by unexplained peripheral eosinophilia along with evidence of end-organ damage. Cardiac involvement is the most life-threatening consequence and is frequently underreported with a prevalence of around 5%. The gold standard for diagnosis is myocardial biopsy, but less-invasive imaging such as cardiac MR (CMR) has been frequently used to help with the diagnosis. We are presenting a unique case of a patient diagnosed with Eosinophilic myocarditis (EM) supported by CMR with rapid improvement after starting steroid treatment. Case Presentation. A 67-year-old African American female with extensive cardiovascular disease history presenting with chest pain was diagnosed with EM secondary to hypereosinophilic syndrome (HES). Lab workup revealed absolute eosinophils of

). Transthoracic echocardiography showed mild reduction in left ventricular function and a large obliterating thrombus in the right ventricular apex. CMR showed increased signal intensity at the left ventricular and right ventricular apex, consistent with myocardial edema. Subsequently, the patient was placed on dexamethasone 10 mg daily with significant symptomatic improvement. Discussion. EM is a rare complication of hypereosinophilic syndrome and can mimic common cardiovascular diseases such as acute exacerbation of heart failure or myocardial infarction. A high index of suspicion is essential especially in the setting of suggestive lab workup. CMR is a promising noninvasive and cost-effective alternative for myocardial biopsy in diagnosis.
A Review of the Impacts of Climate Change on Tourism in the Arid Areas: A Case Study of Xinjiang Uygur Autonomous Region in China
Authors: Shijin Wang , Xinggang Ma , Jia Xie
Published: July 2022

Tourism is more sensitive and susceptible in global arid regions to climate change than other sectors, and climate change mainly affects the behavior of tourists, selection of tourist destinations, tourism resources, and tourism safety. China’s Xinjiang Uygur Autonomous Region (XUAR) is a representative area of the global arid region. To review its comprehensive impacts of climate change on tourism has indicative significance for the global arid region tourism industry to cope with climate change impacts. On the whole, the impacts of climate change on tourism in the XUAR will coexist with opportunities and challenges both at present and in the future. The XUAR is experiencing or will experience climatic process of warming and wetting. For the tourism climate comfort and extension of suitable travel period, the opportunities far outweigh the risks (high reliability). However, future climate change is expected to have great negative effects on cultural heritages, glacier and snow resources, and agricultural landscapes in arid areas of northwest China (high reliability). The above impacts are potential and long-term, and the measures should be taken as soon as possible to mitigate and adapt to climate change challenges to tourism.
Mechanical Behavior of Reactive Powder Concrete Subjected to Biaxial Loading
Authors: Yu Ziruo , Li Zhiguang , Jiang Yuran , Wang Yue
Published: July 2022

To investigate the biaxial mechanical characteristics of reactive powder concrete (RPC), RPC plate specimens and bone‐shaped specimens were tested under compression‐compression and compression‐tension loadings, respectively. The strengths and strains of the specimens were recorded, and the crack patterns and failure modes in various stress states were examined. Based on the test data, the characteristics of biaxial strength were analyzed, and a biaxial failure criterion was established. The characteristics of major stress‐strain curves and failure modes in different biaxial stress states were determined. The results show that the ratio between the biaxial compression strength and the uniaxial compression strength was 1.44–1.58 for RPC. When the stress ratio under compression‐tension was −0.05, the tensile strength decreased by 48%. Under compression‐compression, the proportional limit of RPC was about 95%, and its peak strain was high. Under compression‐tension, as the compressive stress increased, the elastic modulus decreased, and the peak strain in the tensile direction increased. When the RPC specimens were under compression‐compression, the failure mode of RPC was splitting failure. Under compression‐tension, the failure mode changed from single‐crack tensile failure to multicrack compressive failure with increasing confining stress.
[Retracted] Red Raspberry Extract Decreases Depression‐Like Behavior in Rats by Modulating Neuroinflammation and Oxidative Stress
Authors: Chen Yanhua , Yang Xia , Li Hui , Fang Jianqun
Published: July 2022

Objective. Red raspberry serves as a proven natural product to produce anti‐inflammatory, antioxidant, and anticancer functions, but limited findings are available on its effects on depression. This study, by using a chronic unpredictable mild stress‐ (CUMS‐) induced depression model, thus investigated the effects and underlying mechanism of red raspberry extract (RRE) on depressive behavior, inflammation, and oxidative stress. Methods. Different treatments were given after random grouping of Sprague‐Dawley rats, including no intervention (control), CUMS induction, and CUMS+different concentrations of RRE, and subsequently, depression‐like behavior tests were performed. HE staining was designed to observe the pathological damage of the hippocampal tissue in rats. The levels of oxidative stress, endocrine hormones, and inflammatory factors were determined by biochemical assay and ELISA, and gene expression (mRNA and protein) in the hippocampal tissue by qRT‐PCR and Western blot. Results. On completion of CUMS treatment, the rats showed severe depression‐like behavior, with obvious hippocampal tissue damage, oxidative inflammatory response, and endocrine imbalance. Importantly, RRE treatment significantly improved such depression‐like behavior and attenuated histopathological damage in CUMS rats when reducing inflammation and oxidative stress and endocrine imbalance with upregulation of glutathione (GSH), superoxide dismutase (SOD), and interleukin‐ (IL‐) 10 and downregulation of adrenocorticotropic hormone (ACTH), corticosterone (CORT), malondialdehyde (MDA), IL‐1β, cyclooxygenase‐ (COX‐) 2, and human macrophage chemoattractant protein‐ (MCP‐) 1. In addition, for CUMS rats, RRE was a contributor to increasingly expressed brain‐derived neurotrophic factor (BDNF), neurotrophic tyrosine receptor kinase 2 (TrkB), and p‐mTOR but inhibited p‐GSK‐3β expression in the hippocampal tissue. All the above antidepressant effects of RRE were concentration‐dependent. Conclusion. By regulating neuroinflammation, oxidative stress response, endocrine level, and BDNF/TrkB level, RRE showed potential efficacy in alleviating depression‐like behavior and histopathological damage of hippocampal tissue in CUMS rats by regulating the GSK3β and mTOR signaling pathways.
