CD34 ,a marker of microvessel, was selected to measure microvessel density (MVD) in the endometrium.Fifteen women who were found to have no condition with normal menstrual cycles were set as control group.Results VEGF immunoreactivity in glandular epithelia cells was significantly lower in the hyperplastic endometrium than that of controls(P < 0. 05). There was no significant difference in VEGF protein level between proliferative DUB endometrium and that of controls. A positive correlation was found between glandular VEGF and MVD in the endometrium(r=0. 666, P<0.05). Conclusion The anovulatory DUB is associated with down-regulation of VEGF in the endometrium, and decreased secretion of VEGF will result in the disruption of angiogenesis, as a clinical manifestation of irregular bleeding.展开更多

Despite its negative effects on health outcomes, dysfunctional coping remains undiagnosed and untreated in HIV patients. Therefore, it would seem important to diagnose dysfunctional coping in HIV-patients in order to enable health care providers’ plan and execute intervention and treatment strategies in a population of HIV-patients/HIV-infected persons, to reduce health problems that may be associated with it. Aims/Objectives: 1) To identify elements of dysfunctional coping in HIV-patients. 2) To screen HIV-infective persons for dysfunctional coping. 3) To assess prevalence of dysfunctional coping among HIV-patients. 4) To assess association of duration of HIV-infection (survivability) with dysfunctional coping in HIV-infected persons. Methods: A cross-sectional descriptive study was carried out, to diagnose dysfunctional coping in HIV-infected patients. Subjects were HIV patients receiving HAART at Ahmadu Bello University Teaching Hospital (ABUTH), Zaria, Nigeria. Over 110 HIV-infected persons were screened for dysfunctional coping, using 28-item Brief Cope Questionnaire. Results: After various forms of statistical analyses were performed on the data, results indicate differing prevalent rates for the four key dimensions of dysfunctional coping derived from the Brief-cope questionnaire, used to measure dysfunctional coping in this study;Denial Coping, 68 (61.8 percent), Behavioral Disengagement Coping, 46 (41.8 percent), Substance Use Coping, 24 (21.8 percent), Self-Blame Coping, 61 (55.5 percent);and composite (Integrated/Combined) dysfunctional coping, 49 (44.5 percent). A total prevalence rate of 44.5 percent was reported. Altogether more than 60 percent of the HIV patients screened positive for one dimension of dysfunctional coping or the other. The qui-square analyses revealed an association of denial coping with duration of HIV-infection/survivability. Conclusion/Recommendation: Overall, the study was able to demonstrate that dysfunctional coping was quite common among HIV patients. Dysfunctional coping may be a determinant of health in HIV patients and significantly affect health outcome. It was therefore recommended that interventions focused on coping strategies be integrated into management of HIV patients in order to improve their psychological and physical wellbeing.展开更多

This study develops and tests a theoretical model that identifies factors contributing to DAB. Budget emphasis, leadership behavior structure and consideration, and effectiveness of audit review were examined as antecedents of attitudes toward DAB. The findings produced consistent evidence in support of the theoretical model. It is not an emphasis on meeting budgets that leads to undesirable behavior, but contextual variables, such as leadership behavior structure and effectiveness of audit review.展开更多

Conclusions CREG is constantly present in a model of large myocardial infarction and is decreased at the early stage within the myocardium.The decreased expression of this glycoprotein is not only confined strictly to the infarct or periinfarct zone but also is expressed by cardiac myocytes within the myocardium contralateral to the infarct.Therefore CREG production decreased due to myocardial stress response to injury.展开更多

Among patients with GERD, 33.9% of subjects met Rome criteria compared to 13.5% of non-GERD patients (OR=3.6, 95% CI: 3.1-4.3, P<0.0001). Prevalence of all functional symptoms was higher in overlapping GERD and IBS subjects, when compared with their prevalence in the IBS subjects without GERD or GERD only subjects (P<0.05).CONCLUSION: This finding shows that in overlapping GERD and IBS, other functional abnormalities of the GI tract are also highly prevalent, suggesting a common underlying dysfunction.展开更多

Methods: Pregnant Kunming mice were randomly divided into the normal group, the control group and the treated group. Mice in the treated group were administered with BYHR, and those in the normal group and the control group were administered with normal saline, starting from the very first day of pregnancy (Pd1). On the Pd4, mifepristone (RU486) was subcutaneously injected into mice in the control group and the treated group. Pinopodes expression on endometrial surface at 09:30-10:00 pm on Pd4 (regarded as time point 1, T1) and at 09:30-10:00 am on Pd5 (as time point 2, T2) was determined by scanning electron microscopy. Pregnancy rate and average implanted embryos were observed on Pd7. Results: Pregnancy rate and average implanted embryos in the control group were obviously lower than those in the normal group (all P<0.01), while the two parameters were significantly higher in the treated group (P<0.05, P<0.01, respectively) than those in the control group. In the normal group, abundant developing pinopodes were distributed over the whole endometrial surface in T1, and they were altered to a great deal of fully developed pinopodes in T2. But in the control group, only a few pinopodes were expressed locally on endometrial surface in T1, showing a nonsynchronous figure of development, and they completely disappeared in T2. In the treated group, a lot of developing pinopodes were expressed like those in the normal group but somewhat lagged behind, whereas many fully developed pinopodes were expressed in T2. Conclusion: The decrease of the pinopodes in T1 and the cleaning up of them in T2 is possibly the partial mechanism of mifepristone in inducing embryo implantation dysfunction. It is indicated that BYHR could improve pinopodes expression on endometrial surface, eventually better the uterine receptivity and improve the embryo implantation.展开更多

文摘Dysfunctional audit behavior (DAB) is an accepted problem, associated with decreased audit quality. This study develops and tests a theoretical model that identifies factors contributing to DAB. Budget emphasis, leadership behavior structure and consideration, and effectiveness of audit review were examined as antecedents of attitudes toward DAB. The findings produced consistent evidence in support of the theoretical model. It is not an emphasis on meeting budgets that leads to undesirable behavior, but contextual variables, such as leadership behavior structure and effectiveness of audit review.
文摘Background Cellular Repressor of E1A-stimu-lated gene(CREG) is widely expressed in adult tissues such as the brain,heart,lung,liver,intestine and kidney in mice.It is not known whether tissue CREG is decreased in the common setting of myocardial infarction which may lead to heart failure.We studied the expression and protein localization of CREG and its main receptor(IFR2R) in a mouse model of myocardial infarction.Methods Male mice were randomized to proximal left anterior descending ligation.The animals were killed on day 1,3,7,14,and 28 after ligation to examine gene expression and protein production of CREG and IGF2R from the infarct,peri-infarct,and contralateral zones of infarcted heart.Results There was decreased CREG mRNA production throughout the myocardium at dav 1,and the expression gradually increased at day 28 after myocardial infarction.The decreased expression of this glycoprotein was not confined strictly to the infarct or peri-infarct zones but also expressed by cardiac myocytes within the myocardium in the contralateral normal zone.Levels of CREG protein in the infarct and peri-infarct zones declined to 1/3- to 1/2-fold of normal levels and declined to 1/2- to 2/3- fold in the contralateral zone.Finally,the expression of the IGF2R mRNA transcripts was downregulated at day 3 and 7 after ligation in the infarct and peri-infarct zones,suggesting that the signal transduction pathways necessary for CREG in the heart remain intact as CREG biosynthesis decreases. Conclusions CREG is constantly present in a model of large myocardial infarction and is decreased at the early stage within the myocardium.The decreased expression of this glycoprotein is not only confined strictly to the infarct or periinfarct zone but also is expressed by cardiac myocytes within the myocardium contralateral to the infarct.Therefore CREG production decreased due to myocardial stress response to injury.

文摘AIM:To investigate the association of gastroesophageal reflux disease (GERD) and irritable bowel syndrome (IBS) in Iranian patients and examine the prevalence of functional symptoms of the gastrointestinal tract in patients presenting with either IBS, GERD or both.METHODS: Six thousand four hundred and seventy six patients presented to the Gastro-intestinal (GI) clinic with symptoms of functional dysfunction of GI tract, 1419 patients (62.0% women, 38.0% men; mean age: 37.4±11.5 years) met Rome or Rome criteria(depending on the year of diagnosis)for IBS.2658 patients were diagnosed with GERD based on clinical presentation and endoscopic findings.We assessed other functional symptoms(epigastric pain,nausea,vomiting,belching,constipation and diarrhea)in patients suffering from GERD,IBS or both.RESULTS: Among IBS subjects, 63.6% (69.0% women, 31.0% men; mean age: 36.4±10.3 years) also hadGERD, whereas 34.7% of the non-IBS patients had GERD [odds ratio (OR) =3.2, 95% confidence interval (CI): 2.9-3.7, P<0.0001]. Among patients with GERD, 33.9% of subjects met Rome criteria compared to 13.5% of non-GERD patients (OR=3.6, 95% CI: 3.1-4.3, P<0.0001). Prevalence of all functional symptoms was higher in overlapping GERD and IBS subjects, when compared with their prevalence in the IBS subjects without GERD or GERD only subjects (P<0.05).CONCLUSION: This finding shows that in overlapping GERD and IBS, other functional abnormalities of the GI tract are also highly prevalent, suggesting a common underlying dysfunction.
文摘Objective: To explore the therapeutic mechanism of Bushen Yiqi Hexue recipe (补肾益气血方, BYHR), and observe its effect on pinopodes expression on endometrial surface in mifepristone induced embryo implantation dysfunctional mice. Methods: Pregnant Kunming mice were randomly divided into the normal group, the control group and the treated group. Mice in the treated group were administered with BYHR, and those in the normal group and the control group were administered with normal saline, starting from the very first day of pregnancy (Pd1). On the Pd4, mifepristone (RU486) was subcutaneously injected into mice in the control group and the treated group. Pinopodes expression on endometrial surface at 09:30-10:00 pm on Pd4 (regarded as time point 1, T1) and at 09:30-10:00 am on Pd5 (as time point 2, T2) was determined by scanning electron microscopy. Pregnancy rate and average implanted embryos were observed on Pd7. Results: Pregnancy rate and average implanted embryos in the control group were obviously lower than those in the normal group (all P<0.01), while the two parameters were significantly higher in the treated group (P<0.05, P<0.01, respectively) than those in the control group. In the normal group, abundant developing pinopodes were distributed over the whole endometrial surface in T1, and they were altered to a great deal of fully developed pinopodes in T2. But in the control group, only a few pinopodes were expressed locally on endometrial surface in T1, showing a nonsynchronous figure of development, and they completely disappeared in T2. In the treated group, a lot of developing pinopodes were expressed like those in the normal group but somewhat lagged behind, whereas many fully developed pinopodes were expressed in T2. Conclusion: The decrease of the pinopodes in T1 and the cleaning up of them in T2 is possibly the partial mechanism of mifepristone in inducing embryo implantation dysfunction. It is indicated that BYHR could improve pinopodes expression on endometrial surface, eventually better the uterine receptivity and improve the embryo implantation.

文摘Astrocytes are integral components of the central nervous system,where they are involved in numerous functions critical for neuronal development and functioning,including maintenance of blood-brain barrier,formation of synapses,supporting neurons with nutrients and trophic factors,and protecting them from injury.These roles are markedly affected in the course of chronic neurodegenerative disorders,often before the onset of the disease.In this review,we summarize the recent findings supporting the hypothesis that astrocytes play a fundamental role in the processes contributing to neurodegeneration.We focus onα-synucleinopathies and tauopathies as the most common neurodegenerative diseases.The mechanisms implicated in the development and progression of these disorders appear not to be exclusively neuronal,but are often related to the astrocytic-neuronal integrity and the response of astrocytes to the altered microglial function.A profound understanding of the multifaceted functions of astrocytes and identification of their communication pathways with neurons and microglia in health and in the disease is of critical significance for the development of novel mechanism-based therapies against neurodegenerative disorders.
文摘The adolescent years are a period of profound change,both physically and psychologically.For many,these years are marked by excitement and exploration,but for others,they are fraught with challenges that can lead to significant mental health issues.Depression,in particular,has become an increasingly prevalent concern among adolescents worldwide,and its multifaceted etiology requires a comprehensive approach to understanding and intervention.A recent study on the relationships among negative life events,dysfunctional attitudes,social support,and depressive symptoms in Chinese adolescents offers valuable insights into the complex interplay between various factors contributing to adolescent depression.The authors explore a moderated mediation model to better understand how these factors interact with and contribute to the onset of depression.This article aims to delve into the key findings of the study,highlight its implications for clinical practice,and encourage further research in this critical area.

文摘Cerebral small vessel disease is a neurological disease that affects the brain microvasculature and which is commonly observed among the elderly.Although at first it was considered innocuous,small vessel disease is nowadays regarded as one of the major vascular causes of dementia.Radiological signs of small vessel disease include small subcortical infarcts,white matter magnetic resonance imaging hyperintensities,lacunes,enlarged perivascular spaces,cerebral microbleeds,and brain atrophy;however,great heterogeneity in clinical symptoms is observed in small vessel disease patients.The pathophysiology of these lesions has been linked to multiple processes,such as hypoperfusion,defective cerebrovascular reactivity,and blood-brain barrier dysfunction.Notably,studies on small vessel disease suggest that blood-brain barrier dysfunction is among the earliest mechanisms in small vessel disease and might contribute to the development of the hallmarks of small vessel disease.Therefore,the purpose of this review is to provide a new foundation in the study of small vessel disease pathology.First,we discuss the main structural domains and functions of the blood-brain barrier.Secondly,we review the most recent evidence on blood-brain barrier dysfunction linked to small vessel disease.Finally,we conclude with a discussion on future perspectives and propose potential treatment targets and interventions.

文摘A growing body of evidence suggests that the gut microbiota contributes to the development of neurodegenerative diseases via the microbiota-gut-brain axis.As a contributing factor,microbiota dysbiosis always occurs in pathological changes of neurodegenerative diseases,such as Alzheimer’s disease,Parkinson’s disease,and amyotrophic lateral sclerosis.High-throughput sequencing technology has helped to reveal that the bidirectional communication between the central nervous system and the enteric nervous system is facilitated by the microbiota’s diverse microorganisms,and for both neuroimmune and neuroendocrine systems.Here,we summarize the bioinformatics analysis and wet-biology validation for the gut metagenomics in neurodegenerative diseases,with an emphasis on multi-omics studies and the gut virome.The pathogen-associated signaling biomarkers for identifying brain disorders and potential therapeutic targets are also elucidated.Finally,we discuss the role of diet,prebiotics,probiotics,postbiotics and exercise interventions in remodeling the microbiome and reducing the symptoms of neurodegenerative diseases.

文摘The dramatic increase in intracranial pressure after subarachnoid hemorrhage leads to a decrease in cerebral perfusion pressure and a reduction in cerebral blood flow.Mitochondria are directly affected by direct factors such as ischemia,hypoxia,excitotoxicity,and toxicity of free hemoglobin and its degradation products,which trigger mitochondrial dysfunction.Dysfunctional mitochondria release large amounts of reactive oxygen species,inflammatory mediators,and apoptotic proteins that activate apoptotic pathways,further damaging cells.In response to this array of damage,cells have adopted multiple mitochondrial quality control mechanisms through evolution,including mitochondrial protein quality control,mitochondrial dynamics,mitophagy,mitochondrial biogenesis,and intercellular mitochondrial transfer,to maintain mitochondrial homeostasis under pathological conditions.Specific interventions targeting mitochondrial quality control mechanisms have emerged as promising therapeutic strategies for subarachnoid hemorrhage.This review provides an overview of recent research advances in mitochondrial pathophysiological processes after subarachnoid hemorrhage,particularly mitochondrial quality control mechanisms.It also presents potential therapeutic strategies to target mitochondrial quality control in subarachnoid hemorrhage.
文摘Emerging evidence and perspectives have pointed towards the heart playing an important role in hepatorenal syndrome(HRS),outside of conventional understanding that liver cirrhosis is traditionally considered the sole origin of a cascade of pathophysiological mechanisms directly affecting the kidneys in this context.In the absence of established heart disease,cirrhotic cardiomyopathy may occur more frequently in those with liver cirrhosis and kidney disease.It is a specific form of cardiac dysfunction characterized by blunted contractile responsiveness to stress stimuli and altered diastolic relaxation with electrophysiological abnormalities.Despite the clinical description of these potential cardiac-related complications of the liver,the role of the heart has traditionally been an overlooked aspect of circulatory dysfunction in HRS.Yet from a physiological sense,temporality(prior onset)of cardiorenal interactions in HRS and positive effects stemming from portosystemic shunting demonstrated an important role of the heart in the development and progression of kidney dysfunction in cirrhotic patients.In this review,we discuss current concepts surrounding how the heart may influence the development and progression of HRS,and the role of systemic inflammation and endothelial dysfunction causing circulatory dysfunction within this setting.The temporality of heart and kidney dysfunction in HRS will be discussed.For a subgroup of patients who receive portosystemic shunting,the dynamics of cardiorenal interactions following treatment is reviewed.Continued research to determine the unknowns in this topic is anticipated,hopefully to further clarify the intricacies surrounding the liver-heart-kidney connection and improve strategies for management.

文摘Changes in olfactory function are considered to be early biomarkers of Parkinson’s disease.Olfactory dysfunction is one of the earliest non-motor features of Parkinson’s disease,appearing in about 90%of patients with early-stage Parkinson’s disease,and can often predate the diagnosis by years.Therefore,olfactory dysfunction should be considered a reliable marker of the disease.However,the mechanisms responsible for olfactory dysfunction are currently unknown.In this article,we clearly explain the pathology and medical definition of olfactory function as a biomarker for early-stage Parkinson’s disease.On the basis of the findings of clinical olfactory function tests and animal model experiments as well as neurotransmitter expression levels,we further characterize the relationship between olfactory dysfunction and neurodegenerative diseases as well as the molecular mechanisms underlying olfactory dysfunction in the pathology of early-stage Parkinson’s disease.The findings highlighted in this review suggest that olfactory dysfunction is an important biomarker for preclinical-stage Parkinson’s disease.Therefore,therapeutic drugs targeting non-motor symptoms such as olfactory dysfunction in the early stage of Parkinson’s disease may prevent or delay dopaminergic neurodegeneration and reduce motor symptoms,highlighting the potential of identifying effective targets for treating Parkinson’s disease by inhibiting the deterioration of olfactory dysfunction.
