ABSTRACT

BACKGROUND: The mortality is significantly higher in patients undergoing maintenance hemodialysis (MHD) than in the general population. It is well-known that vascular access (VA) is critical for MHD patients. But the association between VA satisfaction and all-cause mortality in MHD patients is still not clear. The aim of this study was to explore the relationship between VA satisfaction and all-cause mortality in MHD patients with a 30-month follow-up. METHODS: Two hundred twenty-nine MHD patients in two dialysis centers were enrolled in this observational prospective study. VA satisfaction was assessed using the Short Form Vascular Access Questionnaire (VAQ). Health-related quality of life (HRQoL) score was calculated with Short Form 36 (SF-36) questionnaire. Multiple logistic regression analysis was used to evaluate the influencing factors of all-cause mortality. RESULTS: During the 30-month follow-up period, 35 patients dropped out of the study. Among them, 31 patients died, and 4 patients stopped MHD treatment after renal transplantation. Multivariable analyses showed that the age, VAQ total score, social functioning score and dialysis-related complication score of the VAQ, the total score and MCS of the SF-36 were factors influencing all-cause mortality in MHD patients. The Kaplan-Meier curve further showed that the cumulative survival probability was significantly higher in the MHD patients with VAQ scores <7 at baseline than in patients with VAQ scores ⩾7 (p = 0.031). INCLUSION: The present study showed that VA satisfaction was significantly associated with all-cause mortality in MHD patients. These findings suggest that a holistic approach is required for VA choice.

ABSTRACT

Objective: Aloperine (ALO) is an effective quinolizidine alkaloid. Previous research has demonstrated its antiarrhythmic effect by inhibiting voltage-gated sodium currents in rat ventricular myocytes. This study explored its effect on transient outward potassium currents (Ito) in rat atrial myocytes to identify potential targets in the context of ion channel currents. Methods: The Ito characteristics in rat atrial myocytes were recorded using a whole-cell patch-clamp technique. Molecular docking was performed to validate ligand-protein binding interactions. Results: ALO at concentrations of 3 and 10 µM significantly reduced Ito current densities. Gating kinetics analysis revealed ALO's ability to slow Ito activation, hasten inactivation, and prolong transition from inactive to resting state. Molecular docking revealed that ALO could stably bind to KCND2. Conclusion: ALO may inhibit Ito by slowing the activation process, accelerating inactivation, and delaying the recovery time after inactivation, potentially preventing acetylcholine-induced AF.

ABSTRACT

BACKGROUND: The development and progression of hepatocellular carcinoma (HCC) have been reported to be associated with immune-related genes and the tumor microenvironment. Nevertheless, there are not enough prognostic biomarkers and models available for clinical use. Based on seven prognostic genes, this study calculated overall survival in patients with HCC using a prognostic survival model and revealed the immune status of the tumor microenvironment (TME). AIM: To develop a novel immune cell-related prognostic model of HCC and depict the basic profile of the immune response in HCC. METHODS: We obtained clinical information and gene expression data of HCC from The Cancer Genome Atlas (TCGA) and International Cancer Genome Consortium (ICGC) datasets. TCGA and ICGC datasets were used for screening prognostic genes along with developing and validating a seven-gene prognostic survival model by weighted gene coexpression network analysis and least absolute shrinkage and selection operator regression with Cox regression. The relative analysis of tumor mutation burden (TMB), TME cell infiltration, immune checkpoints, immune therapy, and functional pathways was also performed based on prognostic genes. RESULTS: Seven prognostic genes were identified for signature construction. Survival receiver operating characteristic curve analysis showed the good performance of survival prediction. TMB could be regarded as an independent factor in HCC survival prediction. There was a significant difference in stromal score, immune score, and estimate score between the high-risk and low-risk groups stratified based on the risk score derived from the seven-gene prognostic model. Several immune checkpoints, including VTCN1 and TNFSF9, were found to be associated with the seven prognostic genes and risk score. Different combinations of checkpoint blockade targeting inhibitory CTLA4 and PD1 receptors and potential chemotherapy drugs hold great promise for specific HCC therapies. Potential pathways, such as cell cycle regulation and metabolism of some amino acids, were also identified and analyzed. CONCLUSION: The novel seven-gene (CYTH3, ENG, HTRA3, PDZD4, SAMD14, PGF, and PLN) prognostic model showed high predictive efficiency. The TMB analysis based on the seven genes could depict the basic profile of the immune response in HCC, which might be worthy of clinical application.

ABSTRACT

Transition metal oxides with the merits of high theoretical capacities, natural abundance, low cost, and environmental benignity have been regarded as a promising anodic material for lithium ion batteries (LIBs). However, the severe volume expansion upon cycling and poor conductivity limit their cycling stability and rate capability. To address this issue, NiO embedded and N-doped porous carbon nanorods (NiO@NCNR) and nanotubes (NiO@NCNT) are synthesized by the metal-catalyzed graphitization and nitridization of monocrystalline Ni(II)-triazole coordinated framework and Ni(II)/melamine mixture, respectively, and the following oxidation in air. When applied as an anodic material for LIBs, the NiO@NCNR and NiO@NCNT hybrids exhibit a decent capacity of 895/832 mA h g-1 at 100 mA g-1, high rate capability of 484/467 mA h g-1 at 5.0 A g-1, and good long-term cycling stability of 663/634 mA h g-1 at 600th cycle at 1 A g-1, which are much better than those of NiO@carbon black (CB) control sample (701, 214, and 223 mA h g-1). The remarkable electrochemical properties benefit from the advanced nanoarchitecture of NiO@NCNR and NiO@NCNT, which offers a length-controlled one-dimensional porous carbon nanoarchitecture for effective e-/Li+ transport, affords a flexible carbon skeleton for spatial confinement, and forms abundant nanocavities for stress buffering and structure reinforcement during discharge/charging processes. The rational structural design and synthesis may pave a way for exploring advanced metal oxide based anodic materials for next-generation LIBs.

ABSTRACT

OBJECTIVE: To explore the impact of inflammatory factors on the incidence of cerebral small vessel disease (CSVD), we performed a mendelian randomization (MR) study to analyze the causal relationship between multiple inflammatory factors and CSVD imaging markers and utilized summary-data-based mendelian randomization (SMR) analysis to infer whether the impact of instrumental variables (IVs) on disease is mediated by gene expression or DNA methylation. METHODS: Using public databases such as UKB and IEU, and original genome-wide association studies, we obtained IVs related to exposure (inflammatory factors) and outcome (CSVD imaging markers). We performed the inverse variance weighted, weighted median, and MR-Egger methods to assess causal effects between exposure and outcome in univariate MR analysis. To evaluate their heterogeneity, a series of sensitivity analyses were conducted, including the Cochrane Q test, MR-Egger intercept test, MR-Presso, and leave-one-out analysis. We also applied mediation and multivariate MR analysis to explore the interactions between positive exposures on the same outcome. Additionally, we conducted the SMR, which utilizes instruments within or near relevant genes in blood or brain tissues, to elucidate the causal associations with CSVD markers. RESULTS: ABO Univariate MR of multiple cohorts revealed that the risk of small vessel stroke (SVS) increases with elevated levels of TNF-related apoptosis-inducing ligand (TRAIL, OR, 1.23, 95% CI, 1.08-1.39) and interleukin-1 receptor-like 2, (IL-1RL2, OR, 1.29, 95% CI, 1.04-1.61). IL-18 was a potential risk factor for extensive basal ganglia perivascular space burden (BGPVS, OR, 1.02, 95% CI, 1.00-1.05). Moreover, the risk of extensive white matter perivascular space burden (WMPVS) decreased with rising levels of E-selectin (OR, .98, 95% CI, .97-1.00), IL-1RL2 (OR, .97, 95% CI, .95-1.00), IL-3 receptor subunit alpha (IL-3Ra, OR, .98, 95% CI, .97-1.00), and IL-5 receptor subunit alpha (IL-5Ra, OR, .98, 95% CI, .97-1.00). Mediation and multivariate MR analysis indicated that E-selectin and IL-3Ra might interact during the pathogenesis of WMPVS. SMR estimates showed that TRAIL-related IVs rs5030044 and rs2304456 increased the risk of SVS by increasing the expression of gene Kininogen-1 (KNG1) in the cerebral cortex, particularly in the frontal cortex (ßsmr = .10, Psmr = .003, FDR = .04). Instruments (rs507666 and rs2519093) related to E-selectin and IL-3Ra could increase the risk of WMPVS by enhancing DNA methylation of the gene ABO in blood tissue (ßsmr = .01-.02, Psmr = .001, FDR = .01-.03). CONCLUSION: According to MR and SMR analysis, higher levels of TRAIL increased the risk of SVS by upregulating gene expression of KNG1 in brain cortex tissues. In addition, protective effects of E-selectin and IL-3a levels on WMPVS were regulated by increased DNA methylation of gene ABO in blood tissue.

ABSTRACT

Nivolumab can cause fatal myocarditis. We aimed to analyze the clinical characteristics of nivolumab-induced myocarditis and provide evidence for clinical diagnosis, treatment, and prevention. Studies involving nivolumab-induced myocarditis were identified in electronic databases from 2000 to 2023 for retrospective analysis. A total of 66 patients were included, with a median age of 68 years. The median onset time of myocarditis is 11.5 days. The main organs affected in persons presented with myocarditis are heart (100.0%) and skeletal muscle (22.7%). The main clinical manifestations are dyspnea (49.2%), fatigue (47.6%), and myalgias (25.4%). The levels of troponin, troponin T, troponin I, creatine kinase, creatine kinase myocardial band, creatine phosphokinase, C-reactive protein, brain natriuretic peptide, and N-terminal brain natriuretic peptide precursor were significantly increased. Histopathology often shows lymphocyte infiltration, myocardial necrosis, and fibrosis. Myocardial immunological parameters usually present positive. Cardiac imaging often suggests complete heart block, intraventricular conduction delay, arrhythmia, myocardial infarction, edema, left ventricular ejection fractions reduction, ventricular dysfunction, and other symptoms of myocarditis. Forty-two (63.6%) patients achieved remission within a median time of 8 days after discontinuation of nivolumab and treatment with systemic corticosteroids, immunoglobulins, plasmapheresis, and immunosuppressant. Thirty-five patients eventually died attributed to myocarditis (68.6%), cancer (20.0%), respiratory failure (5.7%), and other reasons (5.7%). Nivolumab-induced myocarditis should be comprehensively diagnosed based on clinical symptoms, histopathological manifestations, immunological parameters, and cardiac function imaging examinations. Nivolumab should be discontinued immediately, plasmapheresis and systemic corticosteroids combined with immunoglobulins or immunosuppressants may be an effective treatment.

ABSTRACT

PURPOSE: Extensively-drug-resistant Gram-negative bacteria (XDR GNB)-related post-neurosurgical infection is closely related to mortality, which represents a major challenge for neurosurgeons. There is an urgent need to review and evaluate methods to reduce mortality. METHODS: Both international and Chinese databases were searched independently from their inception to 15 June 2023. A meta-analysis was conducted using RevMan 5.4 to compare the efficacy and safety of intravenous (IV) treatment in combination with intrathecal or intraventricular (ITH/IVT) treatment with IV treatment alone for post-neurosurgical meningitis or ventriculitis due to GNB. Mortality, microbiological clearance and adverse events were considered as primary outcomes. RESULTS: In total, 18 eligible studies involving 602 patients were included in the meta-analysis. The IV + ITH/IVT group was associated with significantly lower mortality (especially in the XDR GNB subgroup) and acceptable safety. In terms of microbiological clearance, a significant decrease was shown in the XDR GNB subgroup. Significant benefits were shown in laboratory parameters and clinical symptoms after patients were treated with ITH/IVT. CONCLUSION: Additional ITH/IVT treatment may promote XDR GNB clearance and reduce mortality. In addition, ITH/IVT administration can improve clinical symptoms and cerebrospinal fluid indicators of patients with post-neurosurgical infections. Significantly, ITH/IVT treatment does not increase the incidence of adverse events at the recommended dose.

ABSTRACT

Ziziphi Spinosae Semen(ZSS) is an edible TCM derived from the dried ripe seeds of Ziziphus jujube Mill. var. spinosa(Bunge)Hu ex H. F. Chou(Rhamnaceae), which has the effects of nourishing the heart, tonifying the liver, calming the heart, tranquilizing the mind, arresting sweating, and promoting fluid production, and is widely used in the treatment and health care of diseases related to cardiovascular, nervous, and immune systems. Jujuboside B(JuB), one of the main active ingredients of ZSS, possesses various pharmacological effects with application values. This paper reviewed the chemical structure and pharmacological effects of JuB. JuB has sedative, hypnotic, antitumor, anti-platelet, anti-inflammatory, and other biological activities, which shows the potential thera-peutic effects on insomnia, tumors, coronary artery disease, airway inflammation, and liver injury. However, there are some limitations to the results of current studies. More comprehensive studies, including basic research and clinical trials, need to be carried out to provide more reliable evidence.

ABSTRACT

Introduction: Online education has become increasingly popular during the COVID-19 pandemic. Despite its potential for breaking down environmental, geographic, time, and space constraints, many scholars have found that online education still has much room for development. Online physical education, and especially dance education, face challenges due to the high demands of physical interactions and safety requirements. However, only a few scholars have explored the psychological motivations in the context of higher education dance students. Therefore, this study enriches this stream of literature by investigating the motivations of students' intention to use online dance learning. Methods: Structural equation modeling is performed in this study. Empirical data were collected from China to examine the relationship between constructs. This study uses self-determination theory to build a theoretical framework and deeply explore the psychological factors that affect students' attitudes and behavior towards online dance learning. Based on self-determination theory and perceived value theory, the study investigates the interrelationships among the seven latent structures: perceived autonomy on flexibility, perceived online class arrangement competence, perceived usage competence, perceived relatedness with instructors, attitudes, perceived value, and intention to use online dance education. Results: The structural equation modelling results indicate that perceived autonomy, perceived competence, and perceived relatedness have a positive influence on attitudes, and attitudes have a positive influence on perceived value and the intention to use online dance education. All hypotheses proposed in the theoretical framework are supported by the empirical data analysis. Discussion: This study extends the self-determination theory to the online dance education context, providing a new perspective for understanding students' motivation to use online dance classes. The research results also provide theoretical support and management inspiration for the sustainable development of art and physical higher education, particularly online dance education.

ABSTRACT

Background and Aims: Prolyl endopeptidase (PREP) is a serine endopeptidase that participates in many pathological processes including inflammation, oxidative stress, and autophagy. Our previous studies found that PREP knockout exhibited multiple benefits in high-fat diet (HFD) or methionine choline-deficient diet-induced metabolic dysfunction-associated fatty liver disease (MAFLD). However, cumulative studies have suggested that PREP performs complex functions during disease development. Therefore, further understanding the role of PREP in MAFLD development is the foundation of PREP intervention. Methods: In this study, an HFD-induced MAFLD model at different time points (4, 8, 12, and 16 weeks) was used to explore dynamic changes in the PREP proline-glycine-proline (PGP)/N-acetyl-seryl-aspartyl-lysyl-proline (AcSDKP) system. To explore its potential value in MAFLD treatment, saline, or the PREP inhibitor, KYP-2047, was administered to HFD-induced MAFLD mice from the 10th to 16th weeks. Results: PREP activity and expression were increased in HFD-mice compared with control mice from the 12th week onwards, and increased PREP mainly resulted in the activation of the matrix metalloproteinase 8/9 (MMP8/9)-PREP-PGP axis rather than the thymosin ß4-meprin α/PREP-AcSDKP axis. In addition, KYP-2047 reduced HFD-induced liver injury and oxidative stress, improved lipid metabolism through the suppression of lipogenic genes and the induction of ß-oxidation-related genes, and attenuated hepatic inflammation by decreasing MMP8/9 and PGP. Moreover, KYP2047 restored HFD-induced impaired autophagy and this was verified in HepG2 cells. Conclusions: These findings suggest that increased PREP activity/expression during MAFLD development might be a key factor in the transition from simple steatosis to steatohepatitis, and KYP-2047 might possess therapeutic potential for MAFLD treatment.

ABSTRACT

Background: Glycosylated hemoglobin (HbA1c) is recommended for diagnosing and monitoring type 2 diabetes. However, the monitoring frequency in real-world applications has not yet reached the recommended frequency in the guidelines. Developing machine learning models to screen patients with poor glycemic control in patients with T2D could optimize management and decrease medical service costs. Methods: This study was carried out on patients with T2D who were examined for HbA1c at the Sichuan Provincial People's Hospital from April 2018 to December 2019. Characteristics were extracted from interviews and electronic medical records. The data (excluded FBG or included FBG) were randomly divided into a training dataset and a test dataset with a radio of 8:2 after data pre-processing. Four imputing methods, four screening methods, and six machine learning algorithms were used to optimize data and develop models. Models were compared on the basis of predictive performance metrics, especially on the model benefit (MB, a confusion matrix combined with economic burden associated with therapeutic inertia). The contributions of features were interpreted using SHapley Additive exPlanation (SHAP). Finally, we validated the sample size on the best model. Results: The study included 980 patients with T2D, of whom 513 (52.3%) were defined as positive (need to perform the HbA1c test). The results indicated that the model trained in the data (included FBG) presented better forecast performance than the models that excluded the FBG value. The best model used modified random forest as the imputation method, ElasticNet as the feature screening method, and the LightGBM algorithms and had the best performance. The MB, AUC, and AUPRC of the best model, among a total of 192 trained models, were 43475.750 (¥), 0.972, 0.944, and 0.974, respectively. The FBG values, previous HbA1c values, having a rational and reasonable diet, health status scores, type of manufacturers of metformin, interval of measurement, EQ-5D scores, occupational status, and age were the most significant contributors to the prediction model. Conclusion: We found that MB could be an indicator to evaluate the model prediction performance. The proposed model performed well in identifying patients with T2D who need to undergo the HbA1c test and could help improve individualized T2D management.

ABSTRACT

In the present study, the contents of seven active components [genipinic acid(GA), protocatechuic acid(PCA), neochlorogenic acid(NCA), chlorogenic acid(CA), cryptochlorogenic acid(CCA),(+)-pinoresinol di-O-ß-D-glucopyranosid(PDG), and(+)-pinoresinol 4'-O-ß-D-glucopyranoside(PG)] of Eucommiae Cortex in aortic vascular endothelial cells of spontaneously hypertensive rats(SHR) were simultaneously determined by ultra-high liquid chromatography-triple quadrupole mass spectrometry(UPLC-MS/MS). The qualified SHR models were selected. The primary aortic endothelial cells(VECs) of rats were separated and cultured by ligation and adherence, followed by subculture. After successful identification, an UPLC-MS/MS method for simultaneously determining the contents of GA, PCA, NCA, CA, CCA, PDG, PG in seven components of Eucommiae Cortex in VECs was established, including specificity, linearity, matrix effect, recovery, accuracy, precision and stability. The established method had the lo-west limit of quantification of 0.97-4.95 µg·L~(-1), accuracy of 87.26%-109.6%, extraction recovery of 89.23%-105.3%, matrix effect of 85.86%-106.2%, and stability of 86.00%-112.5%. Therefore, the established accurate UPLC-MS/MS method could rapidly and simultaneously determine the contents of the seven active components of Eucommiae Cortex in VECs of SHRs, which provided a refe-rence for the study of cellular pharmacokinetics of active components of Eucommiae Cortex extract.

ABSTRACT

Introduction: Default mode network (DMN) is the most involved network in the study of brain development and brain diseases. Resting-state functional connectivity (rsFC) is the most used method to study DMN, but different studies are inconsistent in the selection of seed. To evaluate the effect of different seed selection on rsFC, we conducted an image-based meta-analysis (IBMA). Methods: We identified 59 coordinates of seed regions of interest (ROIs) within the default mode network (DMN) from 11 studies (retrieved from Web of Science and Pubmed) to calculate the functional connectivity; then, the uncorrected t maps were obtained from the statistical analyses. The IBMA was performed with the t maps. Results: We demonstrate that the overlap of meta-analytic maps across different seeds' ROIs within DMN is relatively low, which cautions us to be cautious with seeds' selection. Discussion: Future studies using the seed-based functional connectivity method should take the reproducibility of different seeds into account. The choice of seed may significantly affect the connectivity results.

ABSTRACT

Chronic cerebral hypoperfusion is an important pathological factor in many neurodegenerative diseases, such as cerebral small vessel disease (CSVD). One of the most used animal models for chronic cerebral hypoperfusion is the bilateral common carotid artery stenosis (BCAS) mouse. For the therapy of CSVD and other diseases, it will be beneficial to understand the pathological alterations of the BCAS mouse, particularly vascular pathological changes. A mouse model of BCAS was used, and 8 weeks later, cognitive function of the mice was examined by using novel object recognition test and eight-arm radial maze test. 11.7 T magnetic resonance imaging (MRI) and luxol fast blue staining were used to evaluate the injury of the corpus callosum (CC), anterior commissure (AC), internal capsule (IC), and optic tract (Opt) in the cerebral white matter of mice. Three-dimensional vascular images of the whole brain of mice were acquired using fluorescence micro-optical sectioning tomography (fMOST) with a high resolution of 0.32 × 0.32 × 1.00 µm3. Then, the damaged white matter regions were further extracted to analyze the vessel length density, volume fraction, tortuosity, and the number of vessels of different internal diameters. The mouse cerebral caudal rhinal vein was also extracted and analyzed for its branch number and divergent angle in this study. BCAS modeling for 8 weeks resulted in impaired spatial working memory, reduced brain white matter integrity, and myelin degradation in mice, and CC showed the most severe white matter damage. 3D revascularization of the whole mouse brain showed that the number of large vessels was reduced and the number of small vessels was increased in BCAS mice. Further analysis revealed that the vessel length density and volume fraction in the damaged white matter region of BCAS mice were significantly reduced, and the vascular lesions were most noticeable in the CC. At the same time, the number of small vessels in the above white matter regions was significantly reduced, while the number of microvessels was significantly increased in BCAS mice, and the vascular tortuosity was also significantly increased. In addition, the analysis of caudal rhinal vein extraction revealed that the number of branches and the average divergent angle in BCAS mice were significantly reduced. The BCAS modeling for 8 weeks will lead to vascular lesions in whole brain of mice, and the caudal nasal vein was also damaged, while BCAS mice mainly mitigated the damages by increasing microvessels. What is more, the vascular lesions in white matter of mouse brain can cause white matter damage and spatial working memory deficit. These results provide evidence for the vascular pathological alterations caused by chronic hypoperfusion.

ABSTRACT

BACKGROUND: Health-related quality of life (HRQoL) has been demonstrated to predict mortality in patients receiving maintenance hemodialysis (MHD). Vascular access (VA) is critical for MHD patients. The aim of this study was to investigate the change in HRQoL among MHD patients with a 2-year follow-up and to explore the impact of VA satisfaction on HRQoL in this population. METHODS: 229 MHD patients in two dialysis centers were included in this observational prospective study. VA satisfaction was assessed using the Vascular Access Questionnaire (VAQ). The 36 Item Short-Form Health Survey (SF-36) questionnaire was employed to evaluate HRQoL scores. Multiple logistic regression analysis was used to evaluate the influencing factors of HRQoL. RESULTS: A total of 229 MHD patients were enrolled in the study, and 198 individuals (86.46%) completed the 2-year follow-up. HRQoL decreased statistically significantly from baseline to the 2-year follow-up across all dimensions. Multivariable analyses showed that the overall score, social functioning score, dialysis-related complication score of VAQ influenced HRQoL in the study population. Furthermore, HRQoL total scores and scores on the physical component summary (PCS) and mental component summary (MCS) domains were significantly higher in the satisfied VA group than in the dissatisfied group at baseline. After the 2-year follow-up, patients with a higher level of VA satisfaction reported higher HRQoL than patients with lower VA satisfaction. CONCLUSION: Our data suggested that VA satisfaction was significantly associated with HRQoL in MHD patients. These findings imply that surgeons and nephrologists should incorporate patient satisfaction into VA surgical decision-making.

ABSTRACT

Many resting-state functional magnetic resonance imaging (rs-fMRI) studies have explored abnormal regional spontaneous brain activity in migraine. However, these results are inconsistent. To identify the consistent regions with abnormal neural activity, we meta-analyzed these studies. We gathered whole-brain rs-fMRI studies measuring differences in the amplitude of low-frequency fluctuations (ALFF), fractional ALFF (fALFF), or regional homogeneity (ReHo) methods. Then, we performed a voxel-wise meta-analysis to identify consistent abnormal neural activity in migraine by anisotropic effect size seed-based d mapping (AES-SDM). To confirm the AES-SDM meta-analysis results, we conducted two meta-analyses: activation likelihood estimation (ALE) and multi-level kernel density analysis (MKDA). We found that migraine showed increased regional neural activities in the bilateral postcentral gyrus (PoCG), left hippocampus (HIP.L), right pons, left superior frontal gyrus (SFG.L), triangular part of right inferior frontal gyrus (IFGtriang.R), right middle frontal gyrus (MFG.R), and left precentral gyrus (PreCG.L) and decreased regional intrinsic brain activities were exhibited in the right angular gyrus (ANG.R), left superior occipital gyrus (SOG.L), right lingual gyrus (LING.R). Moreover, the meta-analysis of ALE further validated the abnormal neural activities in the PoCG, right pons, ANG.R, and HIP. Meta-regression demonstrated that headache intensity was positively associated with the abnormal activities in the HIP.L, ANG.R, and LING.R. These findings suggest that migraine is associated with abnormal spontaneous brain activities of some pain-related regions, which may contribute to a deeper understanding of the neural mechanism of migraine.

ABSTRACT

INTRODUCTION: For effective preventive strategies against GORD (gastro-esophageal reflux disease), we assessed the GORD burden from 1990 to 2019. METHODS: The burden of GORD between 1990 and 2019 was evaluated globally, regionally, and nationally. Using ASIR (age-standardized incidence), ASYLDs (age-standardized years lived with disabilitys), we compared them to the GBD world population per 100,000. The estimates were based on 95% uncertainty intervals (UIs). The AAPC (average annual percent change) in incidence, YLDs, along with prevalence rates with associated 95% CIs were estimated. RESULTS: Data to estimate the burden of GORD are scarce till now. The global ASIR of GORD in 2019 was 3792.79 per 100,000, an increase AAPC of 0.112% from 1990. The prevalence of GORD increased with a AAPC of 0.096% to 9574.45 per 100,000. Global ASYLDs in 2019 was 73.63, an increase AAPC of 0.105% from 1990. The GORD burden varies greatly depending on the development level and geographical location. USA demonstrated the most obvious decreasing trend in burden of GORD, while Sweden had an increasing trend. That the increase in GORD YLDs was mediated primarily by the growth and aging of population, was revealed by decomposition analyses. There was an inverse relationship between SDI (socio-demographic index) and GORD-burden. Frontier analyses revealed significant scope of improvement in the status of development at all levels. CONCLUSION: GORD is a public health challenge, especially in Latin America. Some SDI quintiles had declining rates, while some countries experienced increased rates. Thus, resources should be allocated for preventative measures based on country-specific estimates.

ABSTRACT

CONTEXT: Polygonum cuspidatum Sieb. et Zucc (Polygonaceae), the root of which is included in the Chinese Pharmcopoeia under the name 'Huzhang', has a long history as a medicinal plant and vegetable. Polygonum cuspidatum has been used in traditional Chinese medicine for the treatment of inflammation, hyperlipemia, etc. OBJECTIVE: This article reviews the pharmacological action and the clinical applications of Polygonum cuspidatum and its extracts, whether in vivo or in vitro. We also summarized the main phytochemical constituents and pharmacokinetics of Polygonum cuspidatum and its extracts. METHODS: The data were retrieved from major medical databases, such as CNKI, PubMed, and SinoMed, from 2014 to 2022. Polygonum cuspidatum, pharmacology, toxicity, clinical application, and pharmacokinetics were used as keywords. RESULTS: The rhizomes, leaves, and flowers of Polygonum cuspidatum have different phytochemical constituents. The plant contains flavonoids, anthraquinones, and stilbenes. Polygonum cuspidatum and the extracts have anti-inflammatory, antioxidation, anticancer, heart protection, and other pharmacological effects. It is used in the clinics to treat dizziness, headaches, traumatic injuries, and water and fire burns. CONCLUSIONS: Polygonum cuspidatum has the potential to treat many diseases, such as arthritis, ulcerative colitis, asthma, and cardiac hypertrophy. It has a broad range of medicinal applications, but mainly focused on root medication; its aerial parts should receive more attention. Pharmacokinetics also need to be further investigated.

ABSTRACT

In this study, we investigated the preventive effect of Lycium barbarum L. berry extract on age-related macular degeneration (AMD) and the main components responsible for its antioxidant activity. An AMD mouse model was developed by feeding 18-month-old mice with a 1% hydroquinone diet. Meanwhile, the model mice were treated with water extract (LBW) and alcohol extract (LBE) of L. barbarum berries respectively for 3 months. It was found that the retinal structural abnormalities were improved and the oxidation stress and inflammatory imbalance were both attenuated in model mice treated with the extracts of L. barbarum berries. According to the metabolomics analysis of the serum of model mice, LBW regulated the metabolism of unsaturated fatty acids and sphingolipids, while LBE extracts tended to regulate taurine metabolism. On sodium iodate induced oxidative injury of ARPE-19 cells, water extracts of L. barbarum berries eluted with 95% ethanol (LBW-95E) on AB-8 macroporous resin significantly improved the cell viability and attenuated oxidative stress by increasing the superoxide dismutase (SOD) activity and glutathione (GSH) content, decreasing the reactive oxygen species (ROS) content, promoting the entry of nuclear factor erythroid-derived 2-like 2 (Nrf2) into the nucleus and up-regulating the heme oxygenase-1 (HO-1) expression. Scopoletin, N-trans-feruloyltyramine and perlolyrine were identified as the main components of LBW-95E. These results demonstrated that L. barbarum berry extracts protected the retina of aging AMD model mice from degeneration and LBW-95E was the vital antioxidant activity fraction of LBW. These findings suggest that L. barbarum berry extracts might be an excellent natural source for the development of retinal protection-related drugs or dietary supplements.
