The collateral disease theory is a unique component of the theoretical system of traditional Chinese medicine(TCM),which is currently applied to all kinds of diseases related to the collaterals.With the in-depth study of collaterals theory by many practitioners,its advantages in differentiating and treating gynecological diseases are gradually embodied.Based on the theory of collaterals disease,we discussed the pathogenesis,syndrome differentiation and treatment of gynecological diseases,concluded that the deficient collaterals under nourishment and the stagnant and blocked uterine collateral are the important pathogenesis of gynecological illness.Then we pointed out that invigorating the spleen and tonifying the kidney,and unblocking collateral and dissipating stasis are important treatment methods.We discussed the application of collateral disease theory in Tianjin HA's gynecology,and provided certain theoretical basis and clinical reference for the treatment of gynecologic diseases. 展开更多

An automated retinal disease detection system has long been in exis-tence and it provides a safe,no-contact and cost-effective solution for detecting this disease.This paper presents a game theory-based dynamic weighted ensem-ble of a feature extraction-based machine learning model and a deep transfer learning model for automatic retinal disease detection.The feature extraction-based machine learning model uses Gaussian kernel-based fuzzy rough sets for reduction of features,and XGBoost classifier for the classification.The transfer learning model uses VGG16 or ResNet50 or Inception-ResNet-v2.A novel ensemble classifier based on the game theory approach is proposed for the fusion of the outputs of the transfer learning model and the XGBoost classifier model.The ensemble approach significantly improves the accuracy of retinal disease pre-diction and results in an excellent performance when compared to the individual deep learning and feature-based models. 展开更多

Understanding and modeling individuals’behaviors during epidemics is crucial for effective epidemic control.However,existing research ignores the impact of users’irrationality on decision-making in the epidemic.Meanwhile,existing disease control methods often assume users’full compliance with measures like mandatory isolation,which does not align with the actual situation.To address these issues,this paper proposes a prospect theorybased framework to model users’decision-making process in epidemics and analyzes how irrationality affects individuals’behaviors and epidemic dynamics.According to the analysis results,irrationality tends to prompt conservative behaviors when the infection risk is low but encourages risk-seeking behaviors when the risk is high.Then,this paper proposes a behavior inducement algorithm to guide individuals’behaviors and control the spread of disease.Simulations and real user tests validate our analysis,and simulation results show that the proposed behavior inducement algorithm can effectively guide individuals’behavior. 展开更多

Individuals often get lost behind the diagnosis of Alzheimer’s disease (AD) while widespread differences between these patients are morecommon than similarities. Socioemotional Selectivity Theory (SST) suggests that as we age our goals change from future-oriented (acquiringnew information) to present-oriented (enhancing the emotional, especially positive, meaning of encounters). The goal of the current article is to examine whether the principles of SST might also apply for people with AD. Some aspects of SST are found especially in the early stages of AD when awareness is often intact and cognitive impairment is relatively limited. This review has clinical significance for the treatment of AD because it focuses on what is important to the individual rather than treating patients as a homogenous group. It also highlights the importance of social networks and emphasizes the role of the proxy in AD care. Lastly, it suggests that if those with AD (like the healthy elderly) have a positivity bias then positive emotional stimuli/wording/instructions could usefully be employed in their daily treatment. I suggest that SST may be a useful starting point when attempting to address what matters to individuals with AD and conclude by providing a few suggestions for future studies. 展开更多

Traditional Persian medicine (TPM) has diagnostic and preventive comments in most diseases. Readout TPM gives opportunity to know the viewpoints of ancient Iranian scholars for using these opinions in treating ID. In this regard returning to TPM options and modalities can be useful at least as complementary method in treating ID. For understanding the concepts of ID in TPM first of all it is needed to trace ID in TPM and translate them into western medicine language which is the goal of this report. Methodology: This research includes 80 ID mentioned in TIBBE-AKBARI (one of Persian Medicine textbook) for rewriting and comparing with conventional medicine findings. Findings: The majority of clinical signs, symptoms and physical examinations of ID are comparable with modern medicine except the viewpoint of TPM about aetiology which is based on Akhlat and Mezaj theory. By considering no option for antibiotic therapy in ancients time so there is a completely different opinion in treating ID with modern medicine. Conclusion: IDs have different names in TPM and conventional medicine. In contrast to modern medicine in which micro-organism are as etiologic agents, Akhlat and Mezaj theory of TPM has main role for description of ID, the subject which must to be decoded. Although they have completely different opinions in treatment, but with regard to the increasing of antibiotic resistance issue, TPM treatment comments may be useful in future in ID as complementary method beside antibiotics. 展开更多

The purpose of this integrative review is to evaluate research pertaining to self-management programs for older adults with chronic diseases using Albert Bandura’s Social Cognitive Theory (SCT) for behavior change. The focus is application of the SCT domains to self-management programs. The exploration of the current chronic disease self-management research provides an understanding of the Social Cognitive Theory concepts studied in interventional self-management research. The integrative review explicated two areas related to the theory in need of further research. First, social support has not been thoroughly explored as a mechanism for enhancing self-management interventions. Second, moral disengagement was not identified as a focus within chronic disease research raising the question about the impact of moral disengagement on long-term adherence and behavior change. 展开更多

With a history of more than two thousand years, the theory of preventative treatment has been closely followed by the development of modern medical theories on the basis of inheritance by medical experts in the past dynasties, which has been constantly improved and enriched, and deeply applied in the prevention and treatment of serious and multiple diseases. It has achieved great benefits. For women with gynecological diseases, pelvic inflammatory disease patients accounted for a large proportion. Due to the lack of specificity in diagnosis and treatment, the condition is lingering and difficult to cure, so it seriously reduces the quality of life of women, thus affecting the harmony of family and society. From the perspective of prevention, according to the characteristics of each stage of the disease, this paper put forward substantive prevention suggestions and targeted treatment methods, ensuring preventing before disease, preventing progress after disease, and preventing reoccurring after recovery. It has important practical significance for the prevention and treatment of pelvic inflammatory diseases, as well as the development and inheritance of traditional Chinese medicine. 展开更多

Most of the progress in the development of single scale mathematical and computational models for the study of infectious disease dynamics which now span over a century is build on a body of knowledge that has been developed to address particular single scale descriptions of infectious disease dynamics based on understanding disease transmission process.Although this single scale understanding of infectious disease dynamics is now founded on a body of knowledge with a long history,dating back to over a century now,that knowledge has not yet been formalized into a scientific theory.In this article,we formalize this accumulated body of knowledge into a scientific theory called the transmission mechanism theory of disease dynamics which states that at every scale of organization of an infectious disease system,disease dynamics is determined by transmission as the main dynamic disease process.Therefore,the transmission mechanism theory of disease dynamics can be seen as formalizing knowledge that has been inherent in the study of infectious disease dynamics using single scale mathematical and computational models for over a century now.The objective of this article is to summarize this existing knowledge about single scale modelling of infectious dynamics by means of a scientific theory called the transmission mechanism theory of disease dynamics and highlight its aims,assumptions and limitations. 展开更多

Nonalcoholic fatty liver disease(NAFLD)refers to fatty liver disease caused by liver injury factors other than alcohol.The disease is characterized by diffuse fat infiltration,including simple steatosis(no inflammatory fat deposition),nonalcoholic fatty hepatitis,liver fibrosis,and so on,which may cause liver cirrhosis,liver failure,and even liver cancer in the later stage of disease progression.At present,the pathogenesis of NAFLD is still being studied.The"two-hit"theory,represented by lipid metabolism disorder and inflammatory reactions,is gradually enriched by the"multiple-hit"theory,which includes multiple factors,such as insulin resistance and adipocyte dysfunction.In recent years,vascular endothelial growth factor B(VEGFB)has been reported to have the potential to regulate lipid metabolism and is expected to become a novel target for ameliorating metabolic diseases,such as obesity and type 2 diabetes.This review summarizes the regulatory role of VEGFB in the onset and development of NAFLD and illustrates its underlying molecular mechanism.In conclusion,the signaling pathway mediated by VEGFB in the liver may provide an innovative approach to the diagnosis and treatment of NAFLD. 展开更多

The pathogenic mechanism of diabetic kidney disease(DKD) is complex. The development of DKD cannot be fully explained by a single mechanism.Traditional Chinese Medicine(TCM) has been applied extensively for the treatment of DKD in China.However, studying the mechanism of DKD using theories and methods that are appropriate for TCM characteristics and searching for theoretical bases for TCM clinical application are topics that still need to be explored and researched. Activation of the transforming growth factor(TGF)-β1/Smad and PI3 K/Akt/mTOR signaling pathways functions as a self-protection mechanism against renal microinflammation in DKD. However, the persistent abnormal overactivation of reactions causes secondary cell dysfunction, cell apoptosis, increased extracellular matrix(ECM) secretion, and eventually renal fibrosis. During this process, the dysregulation of self-balance among a variety of signaling pathways and the loss of self-feedback regulatory mecha-nisms downstream of these signaling pathways are critical causes of the occurrence and development of DKD. TCM may both inhibit the expression or activation of "hyperactive" signaling pathways(NFB, Smad3, and PI3 K/Akt/mTOR) and increase the expression or activation of "deficient" signaling pathways(Smad7 and PTEN) to restore balance to cells with an abnormal pathophysiological status and achieve the goal of DKD treatment. 展开更多

Background:Parkinson’s Disease(PD)with mild cognitive impairment(MCI)(PD-MCI)represents one of the most dreaded complications for patients with PD and is associated with a higher risk of developing dementia.Although transcranial direct current stimulation(tDCS)has been demonstrated to improve motor and non-motor symptoms in PD,to date,no study has investigated the effects of tDCS on Theory of Mind(ToM),i.e.,the ability to understand and predict other people’s behaviours,in PD-MCI.Methods:In this randomized,double-blind,sham-controlled study,we applied active tDCS over the medial frontal cortex(MFC)to modulate ToM performance in twenty patients with PD-MCI.Twenty matched healthy controls(HC)were also enrolled and were asked to perform the ToM task without receiving tDCS.Results:In the patients with PD-MCI,i)ToM performance was worse than that in the HC,ii)ToM abilities were poorer in those with fronto-executive difficulties,and iii)tDCS over the MFC led to significant shortening of latency for ToM tasks.Conclusions:We show for the first time that active tDCS over the MFC enhances ToM in patients with PD-MCI,and suggest that non-invasive brain stimulation could be used to ameliorate ToM deficits observed in these patients. 展开更多

Human social interaction is essential in daily life and crucial for a promising life,especially in people who suffer from disease.Theory of Mind(ToM)is fundamental in social interaction and is described as the ability to impute the mental states of others in social situations.Studies have proposed that a complex neuroanatomical network that includes the frontal cortex mediates ToM.The primary neuropathology of Parkinson’s disease(PD)involves the frontal-striatal system;therefore,patients with PD are expected to exhibit deficits in ToM.In this review,we summarize the current research with a particular focus on the patterns of impaired ToM,potential mediators of ToM,and the impact of ToM deficits on clinical disability in PD.Further studies to investigate the progression of ToM and its relationship with dementia in subjects in PD are needed. 展开更多

Objective To investigate therelationships between serum concentration of insulin -like growth factor - I (IGF-I) and left ventricular function as well as coronary collateral circulation in patients with coronary artery disease (CAD) . Methods In 41 patients with CAD and 15 control subjects without CAD, the concentrations of serum IGF - I were measured using radioimmunoassay. The relationships between the concentration of serum IGF - I and Leaman coronary artery score, Rentrop grade of coronary collateral circulation, left ventricular ejection fraction (LVEF) as well as left ventricular wall motion Cortina score were assessed. Results 1. There was no significant difference in the mean level of serum IGF -I between the CAD group and the control group (107. 92±44.74 ng/ml vs 113.05 ±33. 65 ng/ml, P> 0. 05), but the IGF - I concentrations in the subgroup with collateral circulation were significantly greater than that in the control group (147. 33 ±29. 92 ng/ml vs 113. 05±33. 65 ng/ml, P < 0. 01) or in the subgroup without collateral circulation (147. 33 ±29. 92 ng/ml vs 80. 01±29. 75 ng/ml , P < 0. 01). 2. The serum concentration of IGF -I had no significant correlation to the Leaman coronary artery score. 3. The serum level of IGF -I had significantly positive correlation to both LVEF ( r = 0. 45, P < 0. 001) and the Rentrop grade of coronary collateral circulation ( r = 0. 74, P < 0. 001), and was negatively related to the left ventricular wall motion Cortina score (r = -0. 53, P < 0. 001). 4. The Leaman coronary artery score had no significant correlation to the Rentrop grade of coronary collateral circulation. 5. The Leaman coronary artery score was related to neither the LVEF nor the Cortina score in the whole CAD group. In the subgroup without coronary collateral circulation, however, the Leaman score had significantly negative correlation to LVEF ( r = - 0. 46, P < 0. 05) and positive correlation to the Cortina score (r = 0. 47, P < 0. 05) . Conclusions The serum concentration of IGF -I was associated with both left ventricular function and coronary collateral circulation in patients with CAD. IGF -I may play a role in promoting coronary collateral circulation and in protecting left ventricular function in patients with coronary artery disease. 展开更多

Background: Coronary artery disease is highly prevalent in India with onset at a younger age. Coronary collateral circulation plays an important role in protecting myocardium from infarction, preserving myocardial contractility and reducing cardiovascular events. The objective of the present study is to assess the pattern of coronary collateral circulation in known cases of coronary artery disease with correlation to age, gender and degree of occlusion. Method: This is a retrospective study done on 200 preoperative angiograms in patients with coronary artery disease. Patients were classified according to age, gender and degree of obstruction in major vessels. Collateral vessels were graded according to the Rentrop classification. Patients with collaterals were further classified on the basis of intensity of collaterals into 3 groups: those with no collateralization (Grade 0), poor collateralization (Grade 1) and those with adequate collateralization (Grade 2 - 3). Results: Collateral development was seen in 175 (87.5%) angiograms. Collaterals were seen in 66% for left anterior descending (LAD), 44.5% for circumflex (LCx) and 70.5% for right coronary artery (RCA) block. Coronary collaterals between LAD and posterior descending artery (PDA) via ventricular septal branches were most common pathways. Adequate collaterals were seen in 53% males and 29.3% females (p 50 years and in 32% in cases with age p = 0.014) and 54.8% cases with arterial obstruction > 90%. Conclusion: Collateral circulation between LAD and PDA via ventricular septal branches is the commonest pathway to develop. Although prevalence of LAD occlusion is higher but collaterals develop more for RCA occlusion. Adequate collaterals develop more frequently in males, cases above 50 years and in vessels with >90% obstruction. 展开更多
