    Abstract This paper presents a case example from China, where detailed deliberations were instrumental in bringing together national and subnational managers to tailor implementation protocols for neonatal care strategies at provincial and county levels. The China National Health Development Research Center (CNHDRC) organised deliberations to support the formulation of strategies for improving early essential neonatal care for rural areas. The aim was to help counties, the lowest level jurisdiction in China, learn what could work locally, and to help provinces and the national government learn what should inform national policy and be disseminated widely in China's decentralised health system. It became clear that central-level stakeholders needed to learn how to help counties support the pilots. CNHDRC staff, national-level experts and academics visited pilot provinces and counties to discuss local policies, initiatives and challenges (including with patients), build a common understanding of the project and identify local support needs including by examining health records and observing health facilities. What followed were county-specific reports with priority interventions and implementation plans, which were further refined through county-level meetings. They helped central stakeholders better understand and address variations in county capacities and needs.

    Abstract Previous studies showed that, compared to genotype IV Newcastle disease virus (NDV), genotype VII NDV induced extensive extracellular matrix (ECM) degradation by up-regulating the protein expression of matrix metalloproteinase (MMP)-14 in chicken spleens. To investigate potential relationship between MMP-14 function and the ECM degradation, an in vitro peripheral blood mononuclear cells (PBMCs) infection model was established to study the effect of genotype VII NDV (JS5/05) infection on MMP-14 expression, ECM degradation and cell transmigration. The gene and protein expression levels of MMP-14 in NDV-infected chicken PBMCs were measured by quantitative real-time PCR (qRT-PCR) and Western blot, and the subcellular location of MMP-14 was analyzed using immunofluorescence microscopy. A fluorescence-based collagen degradation assay was optimized to measure ECM degradation in PBMCs. Additionally, parameters of a transwell-based transmigration assay were also optimized to determine chemotaxis and transmigration of virus-infected PBMCs. The results showed that JS5/05 up-regulated significantly the expression of MMP-14 in PBMCs at the mRNA and protein levels compared to genotype IV NDV (Herts/33). MMP-14 was transported towards the membrane and accumulated on the cell surface of the JS5/05-infected cells, whereas it remained mainly in the cytoplasm of the Herts/33-infected cells. Collagen degradation assay showed that JS5/05-infected cells exhibited significant collagen degradation compared to the Herts/33-infected cells, and the areas of collagen degradation co-localized with cell surface MMP-14 in the JS5/05-infected cells. The transwell-based transmigration system showed that the transmigration of the JS5/05-infected PBMCs was enhanced significantly compared to the Herts/33-infected cells. These results demonstrated that genotype VII NDV induced up-regulation and surface accumulation of MMP-14 in PBMCs, leading to enhanced ECM degradation and cell migration, and the assays optimized for this study were useful for investigating the regulation of cell behaviour by NDV.

    Abstract Finite-size effect plays a significant role in topology photonics not to mention in reality all experimental setups are in finite-size. A photonic bandgap is opened in the topological edge state dispersion if a topological photonic crystal with finite width is considered, and the bandgap size relies on the finite-size effect. Pseudospin-preserving and pseudospin-flipping processes can be realized when a selectively switch of the pseudospin of edge states are customized by our designs. Our microwave experiments also successfully demonstrate pseudospin switch-on and -off behaviors in a finite-width photonic crystal. By combining photonic crystals with finite widths, a multi-tunneling proposal of topological photonic crystals can also be achieved. Our study of the finite-size effect will provide new approaches and thoughts to improve the development of topological photonic devices in the future.

    Abstract The purpose of this study was to explore the role and mechanism of the PI3K/AKT/mTOR signaling pathway in painful diabetic neuropathy (PDN). The diabetes mellitus (DM) model was established by intraperitoneal injection of streptozocin into SD rats. After 3 weeks of modeling, the DM + LY group was treated with PI3K inhibitor, the DM + vehicle group was treated with DMSO, and the DM group was untreated. The paw mechanical withdrawal thresholds (MWT) was measured by Von Frey filaments, and the expression of PI3K/AKT/mTOR pathway-related proteins and autophagy marker proteins were analyzed by Western blotting. We found that 3 weeks after modeling, the MWT values of diabetic rats were significantly reduced, p-PI3K, p-AKT and p-mTOR proteins expression in the spinal cord was increased, and Beclin1 and LC3-II expressions were reduced (P < 0.05). After administration of PI3K inhibitor, the MWT values in DM + LY group were improved, and the expressions of p-PI3K, p-AKT and p-mTOR proteins in the spinal cord were decreased significantly, and the expressions of Beclin1 and LC3-II were increased (P < 0.05). However, there were no significant changes in the DM + vehicle group compared with the DM group (P > 0.05). Therefore, we conclude that activation of the PI3K/AKT/mTOR pathway and impaired autophagy may be key factors that cause PDN. Inhibition of the PI3K/AKT/mTOR pathway could promote autophagy activity and alleviate PDN.

    Abstract A novel polypyrrole nanowires coated by graphene oxide (PPy-NWs/GO) has been successfully synthesized by one-step electrochemical method, whose structure was different from previously reported PPy/GO composites. The microbial fuel cell equipped with PPy-NWs/GO as anode was fabricated and compared with PPy-NWs ones. The SEM images show that the synthesized PPy-NWs/GO materials possess more surface areas than PPy-NWs. The electrochemical analysis indicated that PPy-NWs/GO anode had lower charge transfer resistance, which may be attributed to synergistic effect of them. The MFC equipped with PPy-NWs/GO anode have higher circle voltages and the power density is about 22.3 mW/m

    Abstract Circularly polarized photocurrent, observed in p-doped bulk GaAs, varies nonlinearly with the applied bias voltage at room temperature. It has been explored that this phenomenon arises from the current-induced spin polarization in GaAs. In addition, we found that the current-induced spin polarization direction of p-doped bulk GaAs grown in the (001) direction lies in the sample plane and is perpendicular to the applied electric field, which is the same as that in GaAs quantum well. This research indicates that circularly polarized photocurrent is a new optical approach to investigate the current-induced spin polarization at room temperature.

    Abstract A novel polypyrrole nanowires coated by graphene oxide (PPy-NWs/GO) has been successfully synthesized by one-step electrochemical method, whose structure was different from previously reported PPy/GO composites. The microbial fuel cell equipped with PPy-NWs/GO as anode was fabricated and compared with PPy-NWs ones. The SEM images show that the synthesized PPy-NWs/GO materials possess more surface areas than PPy-NWs. The electrochemical analysis indicated that PPy-NWs/GO anode had lower charge transfer resistance, which may be attributed to synergistic effect of them. The MFC equipped with PPy-NWs/GO anode have higher circle voltages and the power density is about 22.3 mW/m2, which is great higher than that of PPy-NWs about 15.9 mW/m2. These improvements of the MFCs may be due to more bacteria on the larger biofilms based on GO nanosheets, indicating that the PPy-NWs/GO is more effective anode for improving electricity generation.
