Despite government efforts, many still prefer motorized transport, citing mobility and safety concerns, exacerbated by insufficient pedestrian infrastructure. This study examines the motivations behind this reliance on motorized vehicles, particularly motorcycles, in Hanoi. Findings reveal safety and convenience as primary factors driving motorized transport use, especially for accessing bus stations. Economic incentives could promote non-motorized travel and public transport adoption. Policy implications highlight the importance of addressing economic factors and improving access infrastructure to manage motorized vehicle reliance and foster sustainable urban mobility in Hanoi.展开更多

With a rise in bicycling on campuses there comes a rise in bicycle collisions with pedestrians walking to and from classes and work. The literature review showed many papers involving bicycle conflict modeling but on roads with motor vehicles. While some aspects of this research can be applied to non-motorized paths, there is a lack of research strictly focusing on only bicycles and pedestrians. This study aims to fill this knowledge gap by developing a model to identify locations on roads and paths (hotspots) on college campuses that are likely to have a bicycle collision and predict the likelihood of a serious bicycle crash on a non-motorized path based on the characteristics of the path. This study identifies those interactions between bicyclists and pedestrians on non-motorized paths on a suburban college campus in Newark, USA. Findings suggest that pedestrian density of a path is a major factor in the maximum speed bicyclists can achieve. The wider the path is, the higher the maximum speed is that a bicyclist can obtain. This is because a wider path width decreases the pedestrian density. The grade of the path has little effect on bicycle speeds. The results of the models were displayed on a GIS map that is visually appealing to a viewer. The paths were color coded based on their level of safety, so it is easy to observe problematic areas of the network. This technique can be applied to the entire campus network of non-motorized paths to study the whole system. This can then be used by planners and designers to identify areas that need upgrading and improve the overall safety of the non-motorized path system.展开更多

Of the two means of surface transportation, the motorized mode is used extensively for utilitarian travel in developed countries. The increasing reliance on motorized travel has contributed to increased traffic congestion, air pollution, and greenhouse emissions. Non-motorized travel has recently received significant attention as a means to reduce congestion and environmental problems and improve human health. However, non-motorized modeling is generally underdeveloped. This study investigated some changes in non-motorized and total travel and the characteristics of the traveling public in 1990, 1995, 2001, and 2009 using a national travel survey. The study also investigated the temporal transferability of linear-regression trip generation models for non-motorized and total travel under such changes. High-income households made fewer non-motorized trips in 1990 and 1995 compared to 2001 and 2009. Persons aged 50 and over showed an increased demand for non-motorized travel, whereas children aged 0 - 15 showed a decreasing preference for non-motorized travel over time. Regarding temporal stability, only the coefficient for single-adult households with no children was stable across all of the analysis years. For both non-motorized and total travel, most model parameter estimates were stable short term but not long term. In general, the total travel models transferred better than non-motorized models, both short term and long term. Despite not finding universal stability in model parameter estimates, the models were marginally able to replicate travel in 2009 relative to the locally estimated 2009 model.展开更多

Reserved area for public transport may be the redesign much more to take advantage of without taking up new space in cities. Redesigned solutions shown in the work of public mass transport and the redesign of non-motorized transport, bicycle and pedestrian paths point to the improved use and safety of movement of passengers, cyclists and pedestrians. This paper presents five redesigned concept designs as improving existing forms of transport and movement of cyclists and pedestrians in cities. Redesigned conceptual designs of motorized and non-motorized transport in cities should serve as ideas for the growing problems of urban development in the segment of insufficient surface for pedestrians and cyclists, as well as sustainable mobility transport people in the city.展开更多

Introduction: Rasagiline is a second-generation monoamine oxidase-B (MAO-B) inhibitor used both as monotherapy and adjunctive therapy for Parkinsons Disease (PD). Methods: A systematic literature search and meta-analysis were performed with randomized control trials that investigated the effects of Rasagiline on motor and non-motor symptoms in individuals with PD. The systematic search was conducted in PubMed, Cochrane, and EBSCO databases. Methodological quality was assessed using the Cochrane Grading Recommendations Assessment, Development and Evaluation approach. Results: Fourteen studies were included in our review. There were trivial to small and statistically significant improvements in motor symptoms for individuals with PD treated with Rasagiline compared to placebo. Non-motor symptoms showed no significant improvement with Rasagiline compared to placebo in five of six meta-analyses. Results were based on very low to moderate certainty of evidence. Conclusion: 1 mg/day Rasagiline significantly improved Parkinsonian motor symptoms in individuals with PD compared with placebo. For all outcomes, the 1 mg/day Rasagiline group was favored over the placebo group.展开更多

The current traffic impact analysis (TIA) is lack of a comprehensive component for non-motorized transportation under redevelopment. For a better guidance of land redevelopment and non-motorized transportation planning, it is necessary to evaluate the negative impact of redevelopment on non-motorized traffic in the TIA. In this paper, an evaluation framework for the impact analysis is built up. We organized the pro- cedures and components of impact evaluation, and proposed the corresponding qualitative and quantitative evaluation indicators for non-motorized traffic under redevelopment. Level of service (LOS) and its criterion are employed for external impact evaluation, and level of safety, convenience, independence, and comfort which are four aspects of quality of service (QOS) are proposed to analyze the internal impact. The framework is applied to a redevelopment study in Shanghai, China. The case study results indicate that the rede- velopment from a residential area to a mixed commercial area has a significant impact on non-motorized traffic. The potential negative impact from both external and internal traffic can be minimized by reasonable improvements in the internal land use design.展开更多

Current treatments often involve synthetic drugs with significant side effects and potential for dependency. This study investigates the effects of a natural supplement combination of Ginkgo Biloba and Acai Extract on cognitive symptoms in a 77-year-old male with PD. The participant underwent a three-month supplementation regimen, with cognitive function assessed using the Montreal Cognitive Assessment (MoCA) test before and after the intervention. The results indicated an improvement in cognitive scores, suggesting that the combination of Ginkgo Biloba and Acai Extract may offer a promising alternative or adjunct to conventional PD treatments. This study highlights the potential of natural supplements in managing PD symptoms and calls for further research with larger sample sizes to confirm these findings. Human data was performed in accordance with the Declaration of Helsinki by the Roxbury District IRB Board (IRB Number: IRB00011767).展开更多

While motor symptoms may be satisfactorily controlled with levodopa therapy or continuous levodopa/carbidopa intestinal gel (LCIG) administration, autonomic, sleep and mental disorders are hard to treat. During the last years, researchers have shifted their interest more to non-motor symptoms, PD being now considered a complex multiorgan impairment. <strong>Objective:</strong> The aim of this study was to describe non-motor symptoms in 40 Romanian patients diagnosed with PD, under conventional and LCIG administration treatment. <strong>Methods: </strong>A cross-sectional observational study was conducted, consisting of two groups of 20 patients each: the first group comprised PD patients who received conventional Levodopa treatment, while the second group was formed of patients receiving LCIG therapy. Various data concerning patient’s age, gender, duration of illness, comorbidities, motor and non-motor symptoms were recorded. The data were processed in SPSS v.20. <strong>Results: </strong>Subjects under continuous LCIG administration, although showing amelioration of motor symptoms, complained more frequently of constipation, mental, and sleeping disorders (statistically significant). Regarding anosmia, orthostatic hypotension, hypersalivation, urinary incontinence and restless legs syndrome, no statistical significant difference was observed between the two groups (p > 0.05). <strong>Conclusion:</strong> Nowadays, more research is conducted on non-motor symptoms in PD patients, as therapeutic measures try to limit these burdens, in order to improve patient’s quality of life.展开更多

It is a complex syndrome with heterogeneous aetiologies, pathogenesis and manifestations. Patients with PD may present with motor symptoms and various non-motor symptoms (NMSs). NMSs have been reported in almost every diagnosed case of PD and usually precede motor symptoms. Multiple factors have been proved to be associated with the occurrence of NMSs in PD, among which genetic differentiation is a featured one. With the development of sequencing techniques, an increasing number of NMS-related genetic factors have been identified. This article reviews some of the latest discoveries in this regard.展开更多

In this regard, in city hall development plans (the format approved by the Ministry of Interior), urban transportation plan has been one of the ten chapters. The purpose of this paper is to survey the content and documents related to the allocation of funds to the traffic sector in the former development program of Kerman city hall and by the way, assess the role of human-oriented transportation among the plans and programs of Kerman city hall. Therefore, the amount of funds allocated to the transport sector in Kerman city hall development plans and programs has been investigated for a period of six years (2009-2014). Comparative analysis method is used for surveying the position and the importance of sustainable transport among planners and urban management. Kerman is the historical city and the most important city in the South East of Iran. Due to uncontrolled population growth in recent decades, a large number of cars added to its pathways, so it is required to have a plan of sustainable transportation programs to be evaluated traffic. Results of the analysis indicate that the budget allocated to the development of the vehicle-oriented transportation is much more than human-oriented transportation and in fact, human-oriented systems of transport such as walking and cycling are considered less than the others. Also in the old fabric of Kerman city that has formed on the basis of the human-oriented transportation, the lowest level of funding is intended to regulate transportation. With this description, it is clear that achieving sustainable development and human-oriented in urban transport sector, it fundamentally needs paradigm shift in urban transport development and revision in the attitudes of managers and planners, and in the meantime it is necessary to correct the programming cycle of urban development along with review of the allocating funds mechanism and to define projects in various sectors. Urban and transport planners can conduct municipalities projects with costing not too much and hereto provide non-motorized styles in the field of urban transport networks. If only allocated apart of the overall funding for roads, highways and city streets to the development of public transport and non-motorized transportation options, the impact would be very high.展开更多

The provision of public recreation opportunities is part of the suite of ecological goods and services that must be considered by many forest managers. Effective access management is predicated on understanding the attitudes and perceptions of recreation users in order to predict and influence visitor behaviour and gauge the acceptance of new management strategies. Potential access management strategies vary given the nature of recreation activities and include: restricting the amount, type, and spatial distribution of use, visitor education, temporal restrictions and enhancing site durability. In this research we examined the views of recreation users on public lands in southwestern Alberta, Canada through implementation of an online survey (n = 945) with a focus on access management options. The results indicate a strong belief that the quality of the recreation experience is declining and that increased management and enforcement are required. More detailed analysis indicates that demographic and user-type variables strongly influence ideas about appropriate management. Forest managers need to engage with, understand, and respond to a wide variety of recreation user needs and preferences.展开更多

Apart from motor symptoms (physical aspects), Parkinson’s disease (PD) is also closely related with various non-motor symptoms (psychological and social aspects) that can undermine quality of life greatly, even in early stages of the disease. Most research studies in this field focus on analysis of motor symptoms in PD sufferers. Although benefits of physical activity for the psychosocial quality of life are well-known, they have been mostly neglected in case of the people suffering from PD. Numerous studies clearly show that training programs can ameliorate the quality of life as far as non-motor functions in PD sufferers are concerned. The only psychological aspects of the disease related to the effects of exercise that have been researched so far are depression and cognitive functions. Depression is the most common denominator of poor quality of life, while dementia often accompanies the Parkinson’s disease. Studies have shown positive effects of exercise on the social life of those suffering from the disease, especially in case of group exercise. Studying psychological and social aspects of such chronic conditions as PD is of utmost importance for monitoring the patient’s adjustment to the disease, functioning with it, as well as the overall well-being and satisfaction with life. Thus far, the results have been pointing towards improvement of the quality of life. Exercise is a readily available method of treatment in case of PD, especially if applied in the early stages of the disease. In addition to reviewing the existing studies on the relation between exercise and quality of life of the patients, this paper will also focus on the way the psychological and social aspects of PD are influenced by exercise.展开更多

文摘Bicycling is an important way for college students and employees to get around campuses. With a rise in bicycling on campuses there comes a rise in bicycle collisions with pedestrians walking to and from classes and work.

This can then be used by planners and designers to identify areas that need upgrading and improve the overall safety of the non-motorized path system.
文摘Transportation systems provide a means for moving people and the goods from which they are spatially separated. Of the two means of surface transportation, the motorized mode is used extensively for utilitarian travel in developed countries. The increasing reliance on motorized travel has contributed to increased traffic congestion, air pollution, and greenhouse emissions. Non-motorized travel has recently received significant attention as a means to reduce congestion and environmental problems and improve human health. However, non-motorized modeling is generally underdeveloped. This study investigated some changes in non-motorized and total travel and the characteristics of the traveling public in 1990, 1995, 2001, and 2009 using a national travel survey. The study also investigated the temporal transferability of linear-regression trip generation models for non-motorized and total travel under such changes. High-income households made fewer non-motorized trips in 1990 and 1995 compared to 2001 and 2009. Persons aged 50 and over showed an increased demand for non-motorized travel, whereas children aged 0 - 15 showed a decreasing preference for non-motorized travel over time. Regarding temporal stability, only the coefficient for single-adult households with no children was stable across all of the analysis years. For both non-motorized and total travel, most model parameter estimates were stable short term but not long term. In general, the total travel models transferred better than non-motorized models, both short term and long term. Despite not finding universal stability in model parameter estimates, the models were marginally able to replicate travel in 2009 relative to the locally estimated 2009 model.

Non-motor symptoms showed no significant improvement with Rasagiline compared to placebo in five of six meta-analyses. Results were based on very low to moderate certainty of evidence. Conclusion: 1 mg/day Rasagiline significantly improved Parkinsonian motor symptoms in individuals with PD compared with placebo. For all outcomes, the 1 mg/day Rasagiline group was favored over the placebo group.

文摘As an important component of city evolution, urban land redevelopment has an impact on transportation system. The current traffic impact analysis (TIA) is lack of a comprehensive component for non-motorized transportation under redevelopment. For a better guidance of land redevelopment and non-motorized transportation planning, it is necessary to evaluate the negative impact of redevelopment on non-motorized traffic in the TIA. In this paper, an evaluation framework for the impact analysis is built up. We organized the pro- cedures and components of impact evaluation, and proposed the corresponding qualitative and quantitative evaluation indicators for non-motorized traffic under redevelopment. Level of service (LOS) and its criterion are employed for external impact evaluation, and level of safety, convenience, independence, and comfort which are four aspects of quality of service (QOS) are proposed to analyze the internal impact. The framework is applied to a redevelopment study in Shanghai, China. The case study results indicate that the rede- velopment from a residential area to a mixed commercial area has a significant impact on non-motorized traffic. The potential negative impact from both external and internal traffic can be minimized by reasonable improvements in the internal land use design.

文摘The high risk of injury resulting from non-motorized vehicle(NMV)crashes has created the goal of using the 3E strategy to comprehensively improve NMV safety.Traditional safety improvement methods identify hot zones generally by crash frequency or density,which is effective for roadway engineering improvements but neglects characteristics related to other improvements such as safety education.As safety education would be more effective if targeted at the residences of crash-involved road users,the traditional approach to hot zones may therefore provide biased results for such alternative countermeasures.After confirming that 77.17%of NMV crashes occurred outside the involved riders’areas of residence,this study compared the differences between the locations of crashes and the residences of NMV crash-involved riders in safety influencing factors and hot zone identification.A Poisson lognormal bivariate conditional autoregressive(PLN-BCAR)model was developed to account for potential correlations between crashes and involved riders.The model was compared with the univariate Poisson lognormal conditional autoregressive(UPLN-CAR)model and the bivariate Poisson lognormal conditional autoregressive(BPLNCAR)model;the PLN-BCAR model outperformed the other two models in its better interpretation of the influencing factors and its more efficient parameter estimation.Model results indicated that crashes were mainly associated with roadway and land use characteristics,while involved road users were mainly associated with socioeconomic and land use characteristics.The potential for safety improvement method was adopted to identify hot zones for countermeasure implementation.Results showed over 60%of the identified hot zones were inconsistent:they needed improvement in either engineering or education but not both.These findings can help target the type of improvement to better utilize resources for NMV safety.
文摘Parkinson’s Disease (PD) is a neurodegenerative disorder characterized by motor and non-motor symptoms, including cognitive impairment. Current treatments often involve synthetic drugs with significant side effects and potential for dependency. This study investigates the effects of a natural supplement combination of Ginkgo Biloba and Acai Extract on cognitive symptoms in a 77-year-old male with PD. The participant underwent a three-month supplementation regimen, with cognitive function assessed using the Montreal Cognitive Assessment (MoCA) test before and after the intervention. The results indicated an improvement in cognitive scores, suggesting that the combination of Ginkgo Biloba and Acai Extract may offer a promising alternative or adjunct to conventional PD treatments. This study highlights the potential of natural supplements in managing PD symptoms and calls for further research with larger sample sizes to confirm these findings. Human data was performed in accordance with the Declaration of Helsinki by the Roxbury District IRB Board (IRB Number: IRB00011767).
文摘Motor symptoms are cardinal clinical features of Parkinson’s disease (PD). Progress in drug therapy and rehabilitation has been presenting beneficial effect for motor symptoms. However, non-motor symptoms and signs in PD have been accumulated growing attentions and its amelioration may also give beneficial effect for PD patients’ and their care givers’ quality of life. In this mini-review, I overviewed non-motor symptoms and signs in PD.
文摘<strong>Background: </strong>Parkinson’s disease (PD) remains a challenge for neurologists, particularly in its advanced stages when non-motor symptoms become a burden for the patient. While motor symptoms may be satisfactorily controlled with levodopa therapy or continuous levodopa/carbidopa intestinal gel (LCIG) administration, autonomic, sleep and mental disorders are hard to treat. During the last years, researchers have shifted their interest more to non-motor symptoms, PD being now considered a complex multiorgan impairment. <strong>Objective:</strong> The aim of this study was to describe non-motor symptoms in 40 Romanian patients diagnosed with PD, under conventional and LCIG administration treatment. <strong>Methods: </strong>A cross-sectional observational study was conducted, consisting of two groups of 20 patients each: the first group comprised PD patients who received conventional Levodopa treatment, while the second group was formed of patients receiving LCIG therapy. Various data concerning patient’s age, gender, duration of illness, comorbidities, motor and non-motor symptoms were recorded. The data were processed in SPSS v.20. <strong>Results: </strong>Subjects under continuous LCIG administration, although showing amelioration of motor symptoms, complained more frequently of constipation, mental, and sleeping disorders (statistically significant). Regarding anosmia, orthostatic hypotension, hypersalivation, urinary incontinence and restless legs syndrome, no statistical significant difference was observed between the two groups (p > 0.05). <strong>Conclusion:</strong> Nowadays, more research is conducted on non-motor symptoms in PD patients, as therapeutic measures try to limit these burdens, in order to improve patient’s quality of life.
文摘Under the background of"people-oriented"thought and"green transportation",the idea of"priority for non-motor vehicles"came into being,which can improve the riding environment of non-motor vehicle riders to a certain extent.According to the current situation of priority for non-motor vehicles in the old urban area of Nanchang,through field investigation,questionnaire investigation and interview,this study summarized the existing problems,and put forward optimization suggestions for these problems,in order to provide reference for areas with similar conditions.
文摘Parkinson’s disease (PD) is the second most common neurodegenerative disorder after Alzheimer’s disease. It is a complex syndrome with heterogeneous aetiologies, pathogenesis and manifestations. Patients with PD may present with motor symptoms and various non-motor symptoms (NMSs). NMSs have been reported in almost every diagnosed case of PD and usually precede motor symptoms. Multiple factors have been proved to be associated with the occurrence of NMSs in PD, among which genetic differentiation is a featured one. With the development of sequencing techniques, an increasing number of NMS-related genetic factors have been identified. This article reviews some of the latest discoveries in this regard.

文摘There are many documented sex differences in the clinical course,symptom expression profile,and treatment response of Parkinson’s disease,creating additional challenges for patient management.Although subthalamic nucleus deep brain stimulation is an established therapy for Parkinson’s disease,the effects of sex on treatment outcome are still unclear.The aim of this retrospective observational study,was to examine sex differences in motor symptoms,nonmotor symptoms,and quality of life after subthalamic nucleus deep brain stimulation.Outcome measures were evaluated at 1 and 12 months post-operation in 90 patients with Parkinson’s disease undergoing subthalamic nucleus deep brain stimulation aged 63.00±8.01 years(55 men and 35 women).Outcomes of clinical evaluations were compared between sexes via a Student’s t-test and within sex via a paired-sample t-test,and generalized linear models were established to identify factors associated with treatment efficacy and intensity for each sex.We found that subthalamic nucleus deep brain stimulation could improve motor symptoms in men but not women in the on-medication condition at 1 and 12 months post-operation.Restless legs syndrome was alleviated to a greater extent in men than in women.Women demonstrated poorer quality of life at baseline and achieved less improvement of quality of life than men after subthalamic nucleus deep brain stimulation.Furthermore,Hoehn-Yahr stage was positively correlated with the treatment response in men,while levodopa equivalent dose at 12 months post-operation was negatively correlated with motor improvement in women.In conclusion,women received less benefit from subthalamic nucleus deep brain stimulation than men in terms of motor symptoms,non-motor symptoms,and quality of life.We found sex-specific factors,i.e.,Hoehn-Yahr stage and levodopa equivalent dose,that were related to motor improvements.These findings may help to guide subthalamic nucleus deep brain stimulation patient selection,prognosis,and stimulation programming for optimal therapeutic efficacy in Parkinson’s disease.
文摘In Iran, the implementation of public transport and non-motorized transport infrastructure warrants the need to allocate adequate funding from the state and city hall. In this regard, in city hall development plans (the format approved by the Ministry of Interior), urban transportation plan has been one of the ten chapters. The purpose of this paper is to survey the content and documents related to the allocation of funds to the traffic sector in the former development program of Kerman city hall and by the way, assess the role of human-oriented transportation among the plans and programs of Kerman city hall. Therefore, the amount of funds allocated to the transport sector in Kerman city hall development plans and programs has been investigated for a period of six years (2009-2014). Comparative analysis method is used for surveying the position and the importance of sustainable transport among planners and urban management. Kerman is the historical city and the most important city in the South East of Iran. Due to uncontrolled population growth in recent decades, a large number of cars added to its pathways, so it is required to have a plan of sustainable transportation programs to be evaluated traffic. Results of the analysis indicate that the budget allocated to the development of the vehicle-oriented transportation is much more than human-oriented transportation and in fact, human-oriented systems of transport such as walking and cycling are considered less than the others. Also in the old fabric of Kerman city that has formed on the basis of the human-oriented transportation, the lowest level of funding is intended to regulate transportation. With this description, it is clear that achieving sustainable development and human-oriented in urban transport sector, it fundamentally needs paradigm shift in urban transport development and revision in the attitudes of managers and planners, and in the meantime it is necessary to correct the programming cycle of urban development along with review of the allocating funds mechanism and to define projects in various sectors. Urban and transport planners can conduct municipalities projects with costing not too much and hereto provide non-motorized styles in the field of urban transport networks. If only allocated apart of the overall funding for roads, highways and city streets to the development of public transport and non-motorized transportation options, the impact would be very high.
文摘Management of recreational access on public forest lands is a complex issue of growing global importance. The provision of public recreation opportunities is part of the suite of ecological goods and services that must be considered by many forest managers. Effective access management is predicated on understanding the attitudes and perceptions of recreation users in order to predict and influence visitor behaviour and gauge the acceptance of new management strategies. Potential access management strategies vary given the nature of recreation activities and include: restricting the amount, type, and spatial distribution of use, visitor education, temporal restrictions and enhancing site durability. In this research we examined the views of recreation users on public lands in southwestern Alberta, Canada through implementation of an online survey (n = 945) with a focus on access management options. The results indicate a strong belief that the quality of the recreation experience is declining and that increased management and enforcement are required. More detailed analysis indicates that demographic and user-type variables strongly influence ideas about appropriate management. Forest managers need to engage with, understand, and respond to a wide variety of recreation user needs and preferences.
文摘Changes in the road environment of Tianjin were intended to speed up the traffic system and shift bicyclists to the metro,bus and car.The metro system was greatly expanded,along with a modernized bus fleet.App-based taxi services were also introduced.In 2007,travellers to the central area were intercepted to determine the starting point of their trip and their travel mode.The most time-efficient trips in 2007 were by bicycle(61%).These trips were re-enacted in 2017 using taxi and metro as it was no longer physically possible to replicate most of the original bicycle trips.Trips greater than 5 km in distance were somewhat faster by taxi than they were by bicycle,but overall,travel time by taxi was greater than by the bicycle for those same trips in 2007.A network analysis of road changes provides explanation why longer trips became more efficient while short trips became less efficient.Travel by metro alone was much longer than the other two methods,but the combination of app-based bicycles and metro would render this travel method the most efficient.

文摘Levodopa preparations remain the preferred drug for Parkinson's disease.However,long-term use of levodopa may lead to a series of motor complications.Previous studies have shown that the combination of levodopa and Zishenpingchan granules(consisting of Radix Rehmanniae preparata,Lycium barbarum,Herba Taxilli,Rhizoma Gastrodiae,Stiff Silkorm,Curcuma phaeocaulis,Radix Paeoniae Alba,Rhizoma Arisaematis,Scorpio and Centipede) can markedly improve dyskinesia and delay the progression of Parkinson's disease,with especially dramatic improvements of non-motor symptoms.However,the efficacy of this combination has not been confirmed by randomized controlled trials.The current study was approved by the Hospital Ethics Committee and was registered in the Chinese Clinical Trial Register(registration number:Chi CTR-INR-1701194).From December 2014 to December 2016,128 patients(72 males and 56 females,mean age of 65.78 ± 6.34 years) with Parkinson's disease were recruited from the Department of Neurology of Longhua Hospital and Shuguang Hospital Affiliated to Shanghai University of Traditional Chinese Medicine in China.Patients were equally allocated into treatment and control groups.In addition to treatment with dopamine,patients in treatment and control groups were given Zishenpingchan granules or placebo,respectively,for 24 weeks.Therapeutic efficacy was assessed using the Unified Parkinson's Disease Rating Scale,on-off phenomenon,Hoehn-Yahr grade,Scales for Outcomes in Parkinson's disease–Autonomic,Parkinson's disease sleep scale,Hamilton Anxiety Scale,Hamilton Depression Scale,Mini-Mental State Examination,and the Parkinson's Disease Quality of Life Questionnaire.Artificial neural networks were used to determine weights at which to scale these parameters.Our results demonstrated that Zishenpingchan granules significantly reduced the occurrence of motor complications,and were useful for mitigating dyskinesia and non-motor symptoms of Parkinson's disease.This combination of Chinese and Western medicine has the potential to reduce levodopa dosages,and no obvious side effects were found.These findings indicate that Zishenpingchan granules can mitigate symptoms of Parkinson's disease,reduce toxic side effects of dopaminergic agents,and exert synergistic and detoxifying effects.
文摘Quality of life encompasses physical, psychological and social aspects of health. Apart from motor symptoms (physical aspects), Parkinson’s disease (PD) is also closely related with various non-motor symptoms (psychological and social aspects) that can undermine quality of life greatly, even in early stages of the disease. Most research studies in this field focus on analysis of motor symptoms in PD sufferers. Although benefits of physical activity for the psychosocial quality of life are well-known, they have been mostly neglected in case of the people suffering from PD. Numerous studies clearly show that training programs can ameliorate the quality of life as far as non-motor functions in PD sufferers are concerned. The only psychological aspects of the disease related to the effects of exercise that have been researched so far are depression and cognitive functions. Depression is the most common denominator of poor quality of life, while dementia often accompanies the Parkinson’s disease. Studies have shown positive effects of exercise on the social life of those suffering from the disease, especially in case of group exercise. Studying psychological and social aspects of such chronic conditions as PD is of utmost importance for monitoring the patient’s adjustment to the disease, functioning with it, as well as the overall well-being and satisfaction with life. Thus far, the results have been pointing towards improvement of the quality of life. Exercise is a readily available method of treatment in case of PD, especially if applied in the early stages of the disease. In addition to reviewing the existing studies on the relation between exercise and quality of life of the patients, this paper will also focus on the way the psychological and social aspects of PD are influenced by exercise.

文摘BACKGROUND Constipation as a most common non-motor symptom of Parkinson's disease(PD),has a higher prevalence compared to the general population.The etiologies of constipation in PD are diverse.In addition to physical weakness and other factors of disease,the lifestyles and eating habits are also important factors.Therefore,the prevalence and influencing factors of constipation may vary among different populations.AIM To determine the prevalence of constipation and analyze relative factors in a cohort of Chinese patients with PD.METHODS All the patients diagnosed with PD according to the movement disorders society criteria were consecutively collected by a self-developed questionnaire.Rome III diagnostic criteria were used to assess functional constipation and Wexner score was used to estimate the severity of constipation.Non-motor symptoms(NMS)were assessed with the non-motor symptoms assessment scale(NMSS).Unified Parkinson's disease Rating Scale III(UPDRS III)was used to evaluate the severity of motor symptoms.The modified Hoehn-Yahr stage was used to evaluate the severity of PD.Cognitive function was assessed using Montreal cognitive assessment(MoCA).Depression and anxiety were rated with the Hamilton depression scale(HAMD)and the Hamilton anxiety scale(HAMA).Quality of life was assessed using the Parkinson’s disease Questionnaire-39 items(PDQ-39).RESULTS Of 166 patients enrolled,87(52.41%)were accompanied with constipation,and 30(34.48%)experienced constipation for 6.30±5.06 years before motor symptoms occurred.Age,Hoehn-Yahr stage,disease duration,levodopa medication times,incidence of motor complications,the scores of UPDRS total,UPDRS III,NMSS,HAMD,HAMA,and PDQ-39 in the constipation group were higher than those in the non-constipation group(P<0.05),but there was no difference in the scores of MoCA,clinical types,or medications between the two groups(P>0.05).There was a higher incidence of depression in patients with constipation(P<0.05),but there were no difference in the incidence of anxiety and cognitive impairment between the two groups(P>0.05).As Hoehn-Yahr stages increased,the severity of constipation increased(P<0.05),but not the incidence of constipation(P>0.05).Pearson correlation analysis showed that constipation was moderately positively correlated with age,Hoehn-Yahr stage,and scores of NMSS,UPDRS III,UPDRS total,PDQ-39,HAMD,and HAMA(r=0.255,0.172,0.361,0.194,0.221,0.237,0.238,and 0.207,P<0.05).Logistic regression analysis showed that only NMSS score was an independent risk factor for constipation(P<0.001).CONCLUSION Our findings confirm that constipation has a relatively high frequency in patients with PD.PD patients with constipation have a higher incidence of depression,which leads to worse quality of life.
