ABSTRACT
Objective:To solve the problem of leg shaking caused by the sudden change of angular acceleration at the joint of periodic motion during circular gait training of lower limb rehabilitation robot. Methods:A kind of quasi-circular gait was proposed, which divided the periodic motion into three phases: start phase, middle phase and end phase. The time was equal in the start phase and the end phase, and could be adjusted with the parameter ratio. The joint trajectories of the two phases were planned by quintic polynomial, and the middle phase was still the circular gait joint trajectory. The trajectory of the proposed quasi-circular gait was simulated. Results:The angular velocity was continuously differentiable and 0, the angular acceleration was continuous and 0, and the end-effector trajectory became flat with the increase of ratio. The results on the physical prototype of the lower limb rehabilitation robot were principally consistent with the simulation, and the machine worked smoothly. Conclusion:The proposed variable quasi-circular gait had smooth angular acceleration at the junction of periodic motions, which effectively solved the jitter problem when using circular gait for lower limb rehabilitation training and avoided secondary injury to the patients.
ABSTRACT
Objective:To study the prevalence of people with disability, and the demand, service policies and service system for assistive technology (AT) services in Australia. Methods:Referring to policy recommendation and indicators in World Health Organizaion's Rehabilitation in Health Systems, Australia's assistive technology service policy framework, services development and trend of development were analyzed by the means of content analysis and development research. Results:There are about 4.4 million people with disability in Australia, of which 1.4 million (32%) with severe or profound disabilities. Federal, state and territorial governments have respectively issued legislation, policy and related service project, including the National Disability Strategy, National Disability Agreement, the National Disability Insurance Scheme, National Standards for Disability Services and others assistance programs to support disability services. There are about two million Australians with disabilities received AT services support from the mentioned programme and scheme. Australia provides more than ten thousands kinds of AT appliances per year, covering all kinds of products in WHO's Priority Assistive Products List. Conclusion:Australia has developed a federal National Disability Strategy, AT service policies and standards, and established federal and state AT insurance and financial support programs for people with disabilities based on the unmet needs of AT services, and federal and state networks for AT services have been established, and service coordination mechanisms at federal and state levels have been established through the National Disability Agreement, covering all types of people with demand of AT in Australia. It meets the requirements of the policy recommendations and assessment indicators in the WHO's Rehabilitation in Health Systems policy guidelines involving AT services. The future development areas in AT will focus on the fields of policy development, ICF implementation, service delivery system, upgrading of service quality and standard, and new technology application.
ABSTRACT
Objective:To study the policy framework and core content of assistive technology (AT) services, compare the current status of AT in countries with different levels of development, and discuss the future development of international policies and services of AT. Methods:Based on the policy and theoretical framework of AT of the United Nations (UN) and World Health Organization (WHO), the policy framework and main contents of international AT services were analyzed; the policies, assistive products and service development of AT services in countries with different levels of development worldwide were compared; and the policy and innovative technology development hotspots of international AT were explored. Results:AT service is an important component of rehabilitation services, and the development of AT services is a key step toward achieving the UN Sustainable Development Goal 3, "Ensure healthy lifestyles and promote the well-being of people of all ages". UN and WHO advocated AT services policy. The framework is based on the UN Convention on the Rights of Persons with Disabilities (CRPD) on articles related to AT, and WHO documents of AT and rehabilitation, such as World Report on Disability, the Global Plan of Action on Disability, Rehabilitation in the Health System, and Rehabilitation in the Health System: A Guide to Action, as well as WHA 71.8 on Assistive Technology, Improving Access to Assistive Technology. The core elements of the international AT policy aim to build integrated, people-centered health services, emphasize the integration of AT into the health system and rehabilitation services, establish and develop AT services in six building blocks of WHO health system, thereby improving access to quality AT to achieve universal health coverage. Further in the fields of technology and service innovation, it proposed to establish a 5P model. High-income countries and low- and middle-income countries are facing many difficulties and large differences in AT service policies, assistive product provision, and service coverage. In the future, adoption of the 5P model proposed by WHO for policy and service delivery and technological changes, and the innovation of assistive product development and AT service models will be the hot spots of AT development. Conclusion:The policy on AT at international level is centered on the concept of UN CRPD and is based on prospect of policy documents issued by the UN and WHO on AT services, with the core objective of developing AT services to provide timely, appropriate, and affordable to persons with disabilities, aging, and people needed to improve their health, quality of life and well-being. It proposes to integrate AT into universal health coverage and to deliver AT service through primary health care in order to achieve the UN SDG 3 goal with full coverage of AT. It proposes to integrate AT into rehabilitation services, i.e. leadership and governance, financing, AT professionals, AT delivery, medicine and technology, and health information system monitoring AT services. There are differneces in AT products and AT delivery due to the globel differneces in economic and social development levels and challenges in access to AT services. It is necessary to develop relevant policies, planning and innovations in assistive products and AT services. AT development in the future will focus on the 5P model of AT to implement reforms in the field of product and service delivery as well as technological innovation in order to improve the coverage, availability, accessibility and affordability, integrate AT into the health system within the framework of universal health coverage, achieve full coverage of universal AT services, and enhance the quality of AT and improve consumers' well-being.
ABSTRACT
Objective To evaluate the effect of Weisu granule combined with conventional therapy in treatment of chronic atrophic gastritis (CAG). Methods A total of 99 CAG patients who met the inclusion criteria were randomly divided into control group (49 cases) and observation group (50 cases) according to random number table method. The control group was treated with quadruple therapy, while the observation group was treated with Weisu granule on the basis of the control group. Both groups were treated for 90 days. Interleukin-6 (IL-6), high-sensitivity C-reactive protein (hs-CRP), tumor necrosis factor-α (TNF-α) were detected by ELISA. The scores of TCM symptoms between the two groups before and after treatment were compared. Adverse reactions during treatment were observed and recorded. The eradication rate of H.pylori was measured by 14C urea breath test, and the clinical efficacy was evaluated. Results The total effective rate was 92.0% (46/50) in the observation group and 73.5% (36/49) in the control group. There were significant differences between the two groups (χ2=5.975, P=0.015). After treatment, the level of serum IL-6, hs-CRP and TNF-α in the observation group was significantly lower than those in the control group (t=7.112, 7.753, 9.310, respectively, all P<0.01). After treatment, the scores of symptoms such as abdominal distension and pain, emotional disturbance, hypochondrium pain and belching in both groups decreased (P<0.01), and those in the observation group was significantly lower than those in the control group (t=12.892, 12.451, 10.596, respectively, P<0.01). The eradication rate of H.pylori was 90.0% (45/50) in the observation group and 24.5% (12/49) in the control group. There was a significant difference between the two groups (χ2=43.381, P<0.01). Conclusions The Weisu granule combined with quadruple therapy has a definite theraputic effect. It can improve the clinical symptoms of patients, improve the clearance rate of H.pylori, and alleviate inflammation.
ABSTRACT
Objective To determine whether a periprosthetic joint infections (PJI) patient derived S.aureus is an appropriate candidate tool bacterium for studying the pathogenesis of S.aureus-induced PJI.Methods Whole genome sequencing data of ST1792 was obtained using the Illumina Hiseq platform of a Staphylocuccal.aureus(S.aureus) strain derived from a PJI prosthesis,and gene functional enrichment analysis based on gene ontology (GO) and kyoto encyclopedia of genes and genomes (KEGG) database was performed.Besides,its biofilm formation ability in drainage fluid,synovial fluid and human plasmin were compared to that in experimental cultures,in order to determine differences in biofilm forming ability in different environment.In addition,based on Illumina Hiseq platform,transcriptome analysis of the S.aureus in the three types of fluid above was performed to determine its gene expression profile and functional enrichment analysis of the differentially expressed genes was conducted through the GO and KEGG database.Finally,adaptability in different human fluid of the S.aureus was analyzed with the transcriptome profile and biofilm formation data.Results The genome of ST1792 consisted of 2 718 coding sequences,including main virulence encoding genes and regulation related genes.Functional enrichment showed no sign of significant missing or major recombination in the bacterial genome.The biofilm mass in plasmin was much higher than that in synovial fluid,both significantly higher than the biofilm mass in TSB.But the biofilm mass in drainage fluid was not statistically different from that in TSB.This revealed that the bacterial biofilm phenotype was significantly altered in PJI human fluid.Transcriptomics sequencing revealed that a huge number of genes were differentially expressed in drainage fluid,synovial fluid and human plasmin compared to TSB.Functional enrichment revealed that the bacterial gene expression profile was different in PJI human fluids,which showed the sophisticated adaptation of the bacterium to human fluid environment.Conclusion As a clinical S.aureus isolated from a PJI patient,ST1792 presents distinct phenotypes and adaptations in vivo,so it is a proper candidate for future studies in the pathogenesis of S.aureus induced PJI.

ABSTRACT
A great number of studies have demonstrated functional abnormalities in children with attention-deficit/hyperactivity disorder (ADHD), although conflicting results have also been reported. And few studies analyzed homotopic functional connectivity between hemispheres. In this study, resting-state functional magnetic resonance imaging (MRI) data were recorded from 45 medication-naïve ADHD children and 26 healthy controls. The regional homogeneity (ReHo), degree centrality (DC) and voxel-mirrored homotopic connectivity (VMHC) values were compared between the two groups to depict the intrinsic brain activities. We found that ADHD children exhibited significantly lower ReHo and DC values in the right middle frontal gyrus and the two values correlated with each other; moreover, lower VMHC values were found in the bilateral occipital lobes of ADHD children, which was negatively related with anxiety scores of Conners' Parent Rating Scale (CPRS-R) and positively related with completed categories of Wisconsin Card Sorting Test (WCST). Our results might suggest that less spontaneous neuronal activities of the right middle frontal gyrus and the bilateral occipital lobes in ADHD children.
ABSTRACT
Attention deficit hyperactivity disorder (ADHD) is a common childhood neuropsychiatric disorder that has been linked to the dopaminergic system. This study aimed to investigate the effects of regulation of the dopamine D4 receptor (DRD4) on functional brain activity during the resting state in ADHD children using the methods of regional homogeneity (ReHo) and functional connectivity (FC). Resting-state functional magnetic resonance imaging data were analyzed in 49 children with ADHD. All participants were classified as either carriers of the DRD4 4-repeat/4-repeat (4R/4R) allele (n = 30) or the DRD4 2-repeat (2R) allele (n = 19). The results showed that participants with the DRD4 2R allele had decreased ReHo bilaterally in the posterior lobes of the cerebellum, while ReHo was increased in the left angular gyrus. Compared with participants carrying the DRD4 4R/4R allele, those with the DRD4 2R allele showed decreased FC to the left angular gyrus in the left striatum, right inferior frontal gyrus, and bilateral lobes of the cerebellum. The increased FC regions included the left superior frontal gyrus, medial frontal gyrus, and rectus gyrus. These data suggest that the DRD4 polymorphisms are associated with localized brain activity and specific functional connections, including abnormality in the frontal-striatal-cerebellar loop. Our study not only enhances the understanding of the correlation between the cerebellar lobes and ADHD, but also provides an imaging basis for explaining the neural mechanisms underlying ADHD in children.

ABSTRACT
Oxaliplatin is effective for the treatment of advanced colorectal cancer,but its application is restricted because of the dose-limiting toxicity.As drug carriers,liposomes are featured with delay release,lesion targeting and they could decrease the side effects of drugs.Active targeting modification of the liposome can change the biological distribution of the anticancer drugs,reduce or reverse multidrug resistance of tumor cells and enhance the effect of anti-tumor drugs.With these characteristics mentioned above,lipsomes containing oxaliplatin may play an important role in the treatment of colorectal cancer.
ABSTRACT
An Aersol-OT (AOT) included microemulsion containing fluorouracil was prepared by using appropriate proportion of oil, co-surfactant and water for increasing the drug transdermal delivery ability. According to the area of microemulsion basing on the pseudo-tertiary phase diagrams, the optimum formulation was screened initially. And the permeation flux of fluorouracil across excised mice skin was determined in vitro using Franz diffusion cell to optimize the formulation further. The effect of the kind of co-surfactant, the content of water, the content of mixed surfactant, the mass ratio of surfactant/cosurfactant (Km) and the drug load on skin permeation of fluorouracil were evaluated. The optimum formulation was composed of 0.5% (w/v) fluorouracil, 30% water, 20% mix-surfactant (AOT/Tween 85, Km = 2) and 49.5% oil (IPM). The cumulative amount permeated of fluorouracil in 12 hour was 1 355.5 microg x cm(-2), 19.1 folds and 7 folds more than 0.5% fluorouracil aqueous solution and 2.5% (w/w) fluorouracil cream, respectively. The permeation of this microemulsion accorded with first-order model. The water/AOT/Tween 85/IPM microemulsion system promoted the permeation of fluorouracil greatly, which may be a promising vehicle for the transdermal delivery of fluorouracil and other hydrophilic drug.
