In this paper, the relevant theoretical knowledge of economic geography, regional economics and so on were synthetically applied. This theoretical knowledge combines the practice of regional differences in rural economic development in China, the regional differences in rural economic development theory, the methods and tools of research become more abundant and perfect. At the same time, the development level of rural economic development and the influencing factors of the differences were studied. The quantitative characteristics of the rural economy were explored by means of statistical analysis. On the one hand, it can provide a reliable basis for the government to formulate a reasonable policy. On the other hand, it can provide reference for the rural economic differences or improve the overall level of rural development.

The current university education has been faced with unprecedented difficulties. It is rooted in the educational philosophy of people and accomplished in the educational practices of people. Positive psychology prompts us to focus on not only the weaknesses of human beings but also their strength; self-description starting teaching is a wonderful work born from traditional teaching methods. The purpose of this paper is to integrate these two positive factors and generate a brand-new self-description starting method. The previous method of "applying action scripts mechanically" is abandoned. Besides, "trying to interpret action scripts" is transformed into "trying to compile action scripts". As a result, teachers and students can find their true selves in teaching and learning.

With the constant improvement and progress of Internet plus and booming growth of Industry 4.0, how to manage the "new employees" in a "new epoch" has become a problem which cannot be avoided. Standing on the judgment that the relationships among enterprises, employees and clients will inevitably grow closer, the change in humanity will become a brand-new topic which requires to be seriously treated in the science of management. In this paper, we propose that the touch point management is the inevitable choice for enterprises to walk towards the future. The ought-to-be state for touch point management is to develop "penguin organizations" and actively promote "touch point manager system" inside enterprises with the help from "client wisdom".

Parkinson's disease (PD) is a chronic neurodegenerative disease, and there is no cure for it at present. Recent research has indicated a link between type 2 diabetes mellitus (T2DM) and PD, which suggested that a treatment to improve insulin resistance for T2DM may be useful for PD patients. Glucose-dependent insulinotropic polypeptide (GIP) belongs to the incretin hormone family, which can promote insulin release and improve insulin resistance. Several GIP analogues have been developed as potential treatments for T2DM. In the present study, a novel long-lasting GIP analogue, D-Ala2-GIP-glu-PAL, has been tested in an acute PD mouse model induced by four 1-Methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) intraperitoneal injections. D-Ala2-GIP-glu-PAL treatment (25 nmol/kg ip.) for 7 days after MPTP treatment improved the locomotor and exploratory activity of mice, and improved bradykinesia and movement balance of mice. D-Ala2-GIP-glu-PAL treatment also restored tyrosine hydroxylase (TH) positive dopaminergic neuron numbers in the substantia nigra and TH levels in the striatum. D-Ala2-GIP-glu-PAL also reduced the chronic inflammation response as seen in astrocyte and microglia activation in the substantia nigra pars compacta (SNpc). D-Ala2-GIP-glu-PAL reversed the reduction of synapse numbers (synaptophysin levels), decreased the ratio of growth factor and apoptosis signaling molecules Bax/Bcl-2, and improved the decrease of p-CREBS133 growth factor signaling in the substantia nigra. Therefore, D-Ala2-GIP-glu-PAL promotes cell survival of dopaminergic neuron in the SNpc by activating the cAMP/PKA/CREB growth factor second messenger pathway that also inhibits apoptosis. The present results demonstrate that D-Ala2-GIP-glu-PAL shows promise as a novel treatment of PD. © 2015 Elsevier Ltd.

Hippocampus | Year: 2014

Rattin, a specific derivative of humanin in rats, shares the ability with HN to protect neurons against amyloid β (Aβ) peptide-induced cellular toxicity. However, it is still unclear whether Rattin can protect against Aβ-induced deficits in cognition and synaptic plasticity in rats. In the present study, we observed the effects of Rattin and Aβ31-35 on the spatial reference memory and in vivo hippocampal Long-term potentiation of rats by using Morris water maze test and hippocampal field potential recording. Furthermore, the probable molecular mechanism underlying the neuroprotective roles of Rattin was investigated. We showed that intra-hippocampal injection of Rattin effectively prevented the Aβ31-35-induced spatial memory deficits and hippocampal LTP suppression in rats; the Aβ31-35-induced activation of Caspase-3 and inhibition of STAT3 in the hippocampus were also prevented by Rattin treatment. These findings indicate that Rattin treatment can protect spatial memory and synaptic plasticity of rats against Aβ31-35-induced impairments, and the underlying protective mechanism of Rattin may be involved in STAT3 and Caspases-3 pathways. Therefore, application of Rattin or activation of its signaling pathways in the brain might be beneficial to the prevention of Aβ-related cognitive deficits. © 2013 Wiley Periodicals, Inc.

The problem of limit cycles for the Kolmogorov model is interesting and significant both in theory and applications. In this paper, we investigate the center-focus problems and limit cycles bifurcations for a class of cubic Kolmogorov model with three positive equilibrium points. The sufficient and necessary condition that each positive equilibrium point becomes a center is given. At the same time, we show that each one of point (1,2) and point (2,1) can bifurcate 1 small limit cycles under a certain condition, and 3 limit cycle can occur near (1,1) at the same step. Among the above limit cycles, 4 limit cycles can be stable. The limit cycles bifurcations problem for Kolmogorov model with several positive equilibrium points are hardly seen in published references. Our result is new and interesting. © 2012 Springer Science+Business Media Dordrecht.

The paper studied the performances of parallel thermoelectric generator (TEG) by theoretical analysis and experimental test. An analytical model of parallel TEG was developed by theoretical analysis and calculation, based on thermodynamics theory, semiconductor thermoelectric theory and law of conservation of energy. Approximate expressions of output power and current of parallel TEG were deduced by the analytical model. An experimental system was built to verify the model. The results indicate that only when all of the thermoelectric modules (TE modules) in the parallel TEG have the same inherent parameters and working conditions, the parallel properties of the TEG are the same as that of common DC power. The existence of contact resistance is just like the increase of the TE module's internal resistance, which leads to the deceases of output power. The thermal contact resistance reduces the output power by reducing the temperature difference between the two sides of the thermocouples. The results derived from the model are basically consistent with the experimental results, the model is suitable for the performance researching and designing of parallel TEG. © 2011 Elsevier Ltd.

Herein, a series of KGdF4:Yb3+/Er3+ upconversion nanoparticles (UCNPs) were synthesized through a one-pot hydrothermal method using polyethylene glycol (PEG) as capping ligands. The phase and microstructure studies show all these as-prepared UCNPs are pure cubic phase and uniformed nanoparticle shape by changing the doped Yb3+ concentration from 18% to 98%. The as-prepared UCNPs can realize the multicolor emissions from yellow to red and the red-to-green (R/G) ratio can be enhanced from 2.05 to 8.35 when Yb3+ varies from 18% to 98%. In addition, the proposed upconversion (UC) mechanisms of these PEGylated UCNPs are investigated in detail. The realization of multicolor tuning and enhanced R/G ratio by only increasing the doping concentration of Yb3+ ions in KGdF4 host indicates that the PEGylated KGdF4:Yb3+/Er3+ UCNPs can find their application on lighting devices, anticounterfeit technology, and even bioimaging field. © 2015 Xionger Qiu and Tiejun Lin.
