国家空间天气监测预警中心(NCSW)从2004年7月1日开始对用户提供空间天气预报服务, 其中包括未来24, 48 h和72 h的F10.7指数和Ap指数预报. 本文对2005－2022年NCSW的F10.7指数和Ap指数的预报结果进行了检验. 通过检验发现, NCSW预报的未来24, 48 h和72 h的F10.7指数平均比实测值偏小; 未来24 h的Ap指数平均比实测值偏大, 未来48 h和72 h的Ap指数平均比实测值偏小. 太阳活动水平越高, F10.7指数的预报误差越大; 但是Ap指数预报误差最大值反而出现在太阳活动下降段. 此外, 通过与跟报模型、14天回归模型、14天回归修正模型、27天回归模型和27天回归修正模型等简单的统计预报模型对比发现, NCSW的预报性能整体优于简单的统计预报模型. 对于F10.7指数, NCSW的预报性能略好于跟报模型, 明显好于4个回归模型, 但是当太阳活动水平较高时, 跟报模型未来72 h的F10.7指数预报性能优于NCSW; 对于Ap指数, 多数情况下, NCSW的报性能明显优于统计预报模型, 但是地磁扰动剧烈时, 27天回归模型预报的Ap指数反而比NCSW的预报更准确.

为了促进栾树资源的开发和利用，通过体外细胞实验和体内动物实验研究了栾树籽油对非酒精性脂肪肝（NAFLD）的保护作用。体外实验采用游离脂肪酸（FFA）诱导人正常肝细胞系Lo-2，建立NAFLD细胞模型，观察栾树籽油的干预对Lo-2细胞脂肪变性以及甘油三酯（TG）含量的影响，观察栾树籽油对NAFLD细胞脂质堆积的影响。体内实验采用高脂饲料饲养诱导建立NAFLD小鼠模型，造模成功后连续灌胃给药7 d，取小鼠血清、肝脏组织，观察肝脏组织病理学，检测血清及肝脏组织总胆固醇（TC）、TG、谷草转氨酶（AST）和谷丙转氨酶（ALT）水平，探讨栾树籽油对NAFLD小鼠肝脏的保护作用。结果显示：通过FFA诱导Lo-2建立NAFLD细胞模型，栾树籽油干预NAFLD细胞24 h后，Lo-2细胞增殖能力增强，显示出一定的细胞保护能力，油红O染色结果表明栾树籽油能显著减少FFA诱导的Lo-2细胞内脂质堆积，降低TG的含量，且呈剂量依赖性；NAFLD小鼠实验表明栾树籽油具有降低血脂、改善脂质沉积和保护肝脏的作用。综上，体内外实验均证明栾树籽油可减少细胞内脂质的积累，从而达到降脂效果。In order to promote the development and utilization of Koelreuteria paniculata plant resources, the protection effect of Koelreuteria paniculata seed oil against non-alcoholic fatty liver disease（NAFLD） was investigated through in vitro cellular experiments and in vivo animal experiments. In vitro experiments were conducted using free fatty acid (FFA)-induced human hepatocytes (Lo-2) to establish a NAFLD cell model to observe the effects of Koelreuteria paniculata seed oil intervention on steatosis and triglyceride (TG) content in Lo-2 cells, and to observe the effect of Koelreuteria paniculata seed oil on lipid accumulation in the NAFLD cell model. Through in vivo experiments, a mice model of NAFLD was established using high-fat diet feeding. After successful modelling, the mice were administered continuously with Koelreuteria paniculata seed oil by gavage for 7 d. Serum and liver tissues of the mice were collected to observe liver histopathology, and the levels of total cholesterol (TC), TG, glutamic transaminase (AST) and glutamic aminotransferase (ALT) were measured to investigate the hepatoprotective effects of Koelreuteria paniculata seed oil on mice with NAFLD. The results showed that NAFLD cell models were established by FFA induction of Lo-2, and after Koelreuteria paniculata seed oil intervened in the model cells for 24 h, the proliferation ability of Lo-2 cells was enhanced and they showed certain cytoprotective ability. The results of oil red O staining showed that Koelreuteria paniculata seed oil could significantly reduce the accumulation of lipids in FFA-induced Lo-2 cells and lower the content of TG, and the effect was concentration-dependent. Experiments on NAFLD mice showed that Koelreuteria paniculata seed oil could lower blood lipids, improve lipid accumulation, and protect the liver. In conclusion, from in vivo and in vitro experiments, Koelreuteria paniculata seed oil can reduce the accumulation of intracellular lipids, thus achieving a lipid-lowering effect.

Talent is a crucial factor for regional development, and its development and cultivation are important dimensions for measuring the innovation capability of a region. Talent attractiveness is the best reflection of the vitality of regional development. The development of the marine economy and the construction of maritime power require continuous attention to maritime talent. Although there is a substantial amount of literature on marine talent, investigations of marine research talent, which is an indispensable part of marine talent, are relatively scarce. This study revealed the flow characteristics and spatial agglomeration features of marine talent, which could provide references for establishing a reasonable mechanism for marine talent flow, enhancing the efficiency of regional talent allocation, and promoting the high-quality development of coastal cities' marine economies. Author information regarding the changes in their affiliations was extracted from research papers published in marine-related core journals in the China National Knowledge Infrastructure (CNKI) from 2000 to 2020, and a corresponding database was constructed. Using complex network analysis methods and techniques, such as ArcGIS and Gephi, the dynamic characteristics of marine research talent mobility were systematically analyzed. The results show that: 1) During the 20-year period, the number of marine research talent mobility showed a changing trend of increasing and then decreasing, and the network exhibited a typical "pyramid structure," which was controlled by a few hub-type node cities. 2) The spatial distribution pattern of marine research talent mobility was relatively stable, forming a diamond-shaped spatial structure with Qingdao as the core and Dalian, Beijing, Shanghai, and Guangzhou as the vertices. Marine research talent migration can be classified into two modes: intracity closed-loop and intercity migration. The proportion of closed-loop migration increased, and the phenomenon of intra-city migration was highlighted. 3) A considerable spatial imbalance existed in the mobility of marine research talent. The spatial distribution of the net inflow of marine research talent tended to be balanced, whereas the outflow of talent tended to be concentrated. The net inflow of marine research talent was active in the eastern and southern regions of China, whereas the net outflow of talent was active in the northeastern, central, and Beijing regions. The problem of high-intensity net inflow in the southern and eastern regions and high-intensity net outflow in the central and northeastern regions began alleviating. 4) The marine research talent mobility network exhibited an obvious core-periphery structure, and the "Matthew effect" was substantial. Qingdao was always at the core of the network, and there was a strong talent flow between the semi-peripheral and core cities. There was also strong relationship flows between them. Marine research talent in peripheral cities flows mainly to core and semi-peripheral cities. Overall, marine research talent is crucial for the development of coastal cities. Their mobility has a profound impact on both the source and destination cities. Therefore, it is necessary to formulate relevant policies based on the city's position within the marine research talent mobility network and optimize the allocation of marine talent, ultimately promoting the development of the marine economy.

Objective To investigate the significance and development prospects of integrating physical education and health within the framework of “Healthy China”. Methods A literature review was conducted using databases such as CNKI and Baidu Scholar to collect and analyze relevant literature on the Healthy China strategy and the integration of physical education and health. Results The transition from “integration of physical education and medicine” to “integration of physical education and health” represents an ideological evolution and conceptual shift that reflects a profound summary of the practical experiences of both central and local governments in the supply-side reform of physical education and medicine. The integration of physical education and medicine has established a representative development model, which will continue to require policy guidance, innovative supply, public recognition, and knowledge enhancement among practitioners. The construction of the integration of physical education and health in China is situated within the context of a public health service system with Chinese characteristics, and “integration of physical education and health” is an important practical direction for the future of “integration of physical education and medicine”. Conclusion The “integration of physical education and medicine” proposed in the 13th Five-Year Plan in 2016 and the “integration of physical education and health” introduced in the 14th Five-Year Plan in 2021 are both macro-guidelines aimed at promoting overall health and proactive health within the framework of “Healthy China”. The construction and development of the integration of physical education and health are of great significance to the Healthy China strategy and play a special role in the prevention and treatment of chronic diseases.

Objective: To investigate the relationship between serum total immunoglobulin E (IgE), Clara cell secretory protein (CCSP), T cell immunoglobulin mucin molecule 3 (TIM-3), severity of disease and prognosis in children with mycoplasma pneumoniae pneumonia (MPP). Methods: 182 children with MPP admitted to Shanxi Children's Hospital from August 2021 to August 2023 were selected as observation group, children were divided into mild group and severe group according to the condition of children with MPP, and children were divided into good prognosis group and poor prognosis group according to the prognosis of children with MPP after treatment. Another 100 healthy children who underwent physical examination during the same period were included in control group. The levels of serum total IgE, CCSP and TIM-3 were detected, the influencing factors of poor prognosis in children with MPP were analyzed by univariate and multivariate Logistic regression analysis. Results: The serum total IgE and TIM-3 in observation group were higher than those in control group, and CCSP was lower than that in control group (P<0.05). The serum total IgE and TIM-3 in severe group were higher than those in mild group, and CCSP was lower than that in mild group (P<0.05). Among the 182 children with MPP, 59 had poor prognosis, with a poor prognosis rate of 32.42%. The serum total IgE and TIM-3 in poor prognosis group were higher than those in good prognosis group, and CCSP was lower than that in good prognosis group (P<0.05). Univariate analysis showed that the level of C-reactive protein (CRP), proportion of severe cases, duration of fever, clinical pulmonary infection score (CPIS) and course of disease in poor prognosis group were higher than those in good prognosis group (P<0.05). Multivariate Logistic regression analysis showed that, long course of disease, high CPIS score, elevated serum total IgE, TIM-3 and decreased CCSP were risk factors for poor prognosis in children with MPP (P<0.05). Conclusion: The abnormal expression of serum total IgE, CCSP and TIM-3 in children with MPP are closely relate to the severity of the disease, the increase of serum total IgE and TIM-3, the decrease of CCSP, the long course of disease and the high CPIS score are risk factors for poor prognosis in children with MPP.

BACKGROUND: The phosphatidylinositol 3-kinase/protein kinase (PI3K/AKT) signaling pathway plays a pivotal role in regulating osteoclast activation, which is essential for maintaining bone homeostasis. Bone destruction in osteoarticular tuberculosis is caused by aberrant osteoclastogenesis induced by Mycobacterium tuberculosis infection. However, the role of the PI3K signaling pathway in Mycobacterium tuberculosis-induced aberrant osteoclastogenesis remains unclear. OBJECTIVE: To investigate the effects and mechanisms of the PI3K/AKT signaling pathway inhibitor BYL-719 on aberrant osteoclastogenesis induced by Mycobacterium tuberculosis. METHODS: RAW264.7 cells were infected with bovine Mycobacterium tuberculosis bacillus calmette-cuerin vaccine, and Ag85B was used for cellular immunofluorescence staining. The cell counting kit-8 assay was employed to determine the safe concentration of BYL-719. There were four groups in the experiment: blank control group, BYL-719 group, BCG group, and BCG+BYL-719 group. Under the induction of receptor activator of nuclear factor kappa-B ligand, the effects of BYL-719 on post-infection osteoclast differentiation and fusion were explored through tartrate-resistant acid phosphatase staining and phalloidin staining. RT-PCR and western blot were used to detect the expression of osteoclast-related genes and proteins, and further investigate the mechanism of action. RESULTS AND CONCLUSION: Immunofluorescence staining showed that RAW264.7 cells phagocytosed Mycobacterium tuberculosis. Cell counting kit-8 data indicated that 40 nmol/L BYL-719 was non-toxic to cells. Tartrate-resistant acid phosphatase staining and phalloidin staining showed that BYL-719 inhibited the generation and fusion ability of osteoclasts following infection. RT-PCR and western blot results also indicated that BYL-719 suppressed the upregulation of osteoclast-specific genes (including c-Fos, NFATc1, matrix metalloproteinase 9, and CtsK) induced by Mycobacterium tuberculosis infection (P < 0.05). Western blot and immunofluorescence staining revealed that BYL-719 inhibited excessive osteoclast differentiation induced by Mycobacterium tuberculosis by downregulating the expression of IκBα-p65. To conclude, BYL-719 inhibits aberrant osteoclastogenesis induced by Mycobacterium tuberculosis through the downregulation of IκBα/p65. Therefore, the IκBα/p65 signaling pathway is a potential therapeutic target for osteoarticular tuberculosis, and BYL-719 holds potential value for the preventing and amelioration of bone destruction in osteoarticular tuberculosis. BYL-719 has the potential to prevent and ameliorate bone destruction in osteoarticular tuberculosis [ABSTRACT FROM AUTHOR]

A neural network adaptive sliding mode controller was proposed for overhead crane with nonlinear and externally disturbance. Firstly, the dynamic model of overhead crane was established by Lagrange method. Then, based on the hierarchical sliding mode controller, the adaptive update rate of the radial basis function neural network weights was designed. The radial basis function neural network was used to compensate the uncertain upper bound caused by the nonlinear and external disturbance in the system, and the particle swarm optimization algorithm was used to optimize the parameters of controller. The stability of the system was proved by constructing a Lyapunov function. Finally, one set of simulation experiments and one set of validation experiments on a established experimental platform were designed. The simulation results show that under the influence of nonlinear and externally disturbance, the neural network adaptive sliding mode controller can quickly achieve the positioning of the trolley and the swing suppression of the load, the controller can eliminate the influence of uncertain upper bound on the system. The experimental results also show that the designed controller can make the overhead crane reach the control target, and has a certain ability to resist disturbance. [ABSTRACT FROM AUTHOR]
