BACKGROUND: Early postural adjustments serve as preparatory measures for forthcoming actions or potential disruptions in posture, thereby facilitating improved movement execution and mitigating destabilizing effects caused by posture interference. OBJECTIVE: To investigate the characteristics of temporal and intensity parameters of key lower limb muscles during early postural adjustment phase when stroke patients with varying levels of balance initiate walking at a self-selected comfortable pace. METHODS: The characteristics of early postural adjustments in 16 stroke patients were observed. Sixteen patients were divided into a non-fall group (n=8) and a fall group (n=8) based on the history of falls and Berg Balance Scale scores. Noraxon inertial sensors and Noraxon Ultium EMG wireless surface electromyography were utilized to collect body kinematic data and surface electromyography data during gait initiation. Muscle activation time and activation sequence of six key muscles in the lower limbs (tibialis anterior, medial and lateral gastrocnemius, rectus femoris, lateral femoris and biceps femoris muscles) during the early postural adjustment phase, as well as normalized electromyography integral values for the four time windows (each 150 ms) before gait initiation, were analyzed. RESULTS AND CONCLUSION: Stroke patients with a history of falls exhibited earlier activation times for the six key muscles in the lower limbs during gait initiation compared with those in the non-fall group. The fall group demonstrated significantly earlier activation times for tibialis anterior, lateral head of gastrocnemius, and vastus lateralis (P < 0.01, P < 0.05). In contrast, the non-fall group displayed a consistent pattern of activating extensor muscles before flexor muscles, with thigh muscle activation preceding calf muscle activation. However, in the fall group, calf extensor muscle activation occurred prior to thigh extensor muscle activation, and the vastus lateralis was activated even earlier. The tibialis anterior was the last activated muscle in both groups. Specifically during T3 (> -300 to -150 ms), the tibialis anterior exhibited significantly higher activity in the fall group compared with the non-fall group (P < 0.05), while the lateral head of gastrocnemius demonstrated significant inhibition during T3 (P < 0.05) and the medial head of gastrocnemius showed significant inhibition during both T3 and T4 (> -150 to 0 ms) stages compared with the non-fall group (P < 0.01, P < 0.05). To conclude, stroke patients with varying balance abilities employ distinct early postural adjustment strategies prior to stepping, as evidenced by differences in muscle activation timing, recruitment order, and muscle activity amplitude. Patients at a high risk of falling exhibit prolonged duration of early postural adjustment and delayed initiation of gait, indicating earlier activation of the tibialis anterior muscle and inhibition of gastrocnemius muscle activity. These delays in gait initiation and variations in muscle recruitment strategies may contribute to unstable posture and an increased susceptibility to falls. [ABSTRACT FROM AUTHOR]

During the “14th Five-Year Plan” period, water ecological environmental protection work in river basins will pay more attention to water ecological protection and restoration based on water environment improvement. The construction and ecological restoration of river and lake ecological buffer zones play an important role in restoring and stabilising the function of water ecosystems, improving water quality and landscape enhancement. This paper takes the ecological buffer zone of village-type rivers and lakes as the research object and explores the construction and landscape planning strategy of ecological buffer zone of village-type rivers and lakes under the perspective of ecological restoration by using literature research and interdisciplinary research methods. By analysing the spatial architecture of buffer strips and delineating their width, we constructed a 1+5+1 landscape strategy model, i.e., one ecological restoration strategy, five spatial structures(the water environment space, the berm space, the artificial wetland space, the terrestrial vegetation space, the pathway space) landscape strategy, and one humanistic landscape strategy. The study aims to provide ideas and theoretical support for the ecological buffer zone restoration programme of village-type rivers and lakes, as well as to provide reference and significance for the planning of projects of the same type.

Objective: To explore the mechanism of hepatitis B virus (HBV) inhibiting M1 macrophages to promote immune escape, and to provide targets and strategies for antiviral therapy. Methods: The human monocyte cell line THP-1 was induced into M1 macrophages with PMA+LPS+IFN-γ. Cell morphological changes and the expressions of CD68, CD86, HLA-DR and functional molecules IL-1β, IL-6, TNF-α in M1 macrophages were detected by flow cytometry and RT-qPCR to identify M1 macrophages. HBV stable replication cell line HepG2.2.15 were co-cultured with M1 macrophages, and the expression of HBV-DNA was detected by qPCR. The expression of CD68, CD86 and HLA-DR were detected by flow cytometry. The expressions of functional molecules TLR4, NLRP3, Caspase-1, pro-caspase-1, caspase-1 p20, IL-1β and IL-18 in M1 macrophages were determined by RT-qPCR and Western blot. Apoptosis rate was detected by flow cytometry, and the expression of apoptosis related protein cleaved-caspase-3 was determined by Western blot. Results: THP-1 was successfully induced to differentiate into M1 macrophages. M1 macrophages inhibited HBV replication (P<0.05). HBV inhibited the expressions of CD68, CD86 and HLA-DR in M1 macrophages（P<0.01). HBV inhibited the expressions of TLR4, NLRP3, Caspase-1, caspase-1 p20, IL-1β and IL-18 in M1 macrophages (P<0.01). HBV induced M1 macrophage apoptosis (P<0.05). Conclusion: HBV inhibits M1 macrophages and their functional molecules TLR4, NLRP3 and downstream factors, reduces the synthesis and secretion of inflammatory factors, induces apoptosis, and then promotes immune escape, resulting in the persistence and replication of HBV in the body.

A brief review of the development of ethnogeography over the past century and geography-oriented theories of minzu over the past 30 years shows that ethnogeography, which is a prominent subdiscipline of geography in the first half of the 20th century, is being eroded to an "important but not conspicuous" field in China. Geography-oriented theories of minzu highlight the significance of "geography" to the development, integration and identification of minzu, whereas the understanding of "geography" is complicated and diverse, and a direction for establishing ethnogeographical theory has not been proposed. Meanwhile, narrow ethnogeography as an independent research field or subdiscipline is devoid of a systematic theoretical system. Considering both modern and contemporary geographical perspectives as well as geography-oriented theories of minzu, three accessible approaches that can strengthen the integrity of ethnogeography and promote the integration of geographical disciplines are proposed. First, the theoretical system of broad ethnogeography could be integrated through a "state-region-place" framework. Second, the multidimensional interpretations of minzu could be bridged with disciplinary traditions of natural science, social science, and humanities to form a threefold "nature-society-humanities" interpretation system. Finally, geographical theories of minzu that emphasizes connection, mobility, and transformation could be developed from the perspective of geography as a discipline rather than a subject. The integrity of ethnogeography will be demonstrated through bridging the gaps among theories, interpretations, and knowledge, and the influence of geography will be extended. More importantly, minzu and nations are understood, not interpreted, geographically. [ABSTRACT FROM AUTHOR]

Teacher's ethics is a major quality for teachers to engage in education, and thereby its construction has the public attributes. From the perspective of public attributes, the current challenges it faces to are as follows: the influence of minority and pluralistic views, the fractured relationship between society and education, and the downgrading of the connotations of teacher's ethics construction. In this regard, all sectors of society need to respond from the dimensions of " untying" and " empowering": providing assistance to educational institutions and teachers to alleviate their constraints; strengthening the ties among all parties, and forming a community for teacher's ethics construction.

No-tillage sowing can effectively alleviate the spring drought for the high corn yield in northeast China. Side-deep fertilization can also avoid seed burning for the fertilizer supply in the middle and late periods of crops. Once the side deep fertilization is applied into no-tillage sowing, the soil height on both sides of the sowing belt can be inconsistent after the fertilizer shovel operation, leading to aggravating the lateral deflection of the seeder under the uneven distribution of surface straw stubble. It is very necessary to improve the sowing depth uniformity and lateral consistency. In this study, the straigh to blique offset furrow opener was designed to reduce the resistance to the increase in the soil backfill during no-tillage sowing, in order to improve the sowing depth uniformity and lateral consistency. The furrow opener was mainly composed of a cutting oblique edge, a retaining positioning plate, and an offset bulldozing plate. The soil was cut and pushed into the side of the fertilizer furrow to widen the seed furrow during the operation. The seeds falling was avoided after the fertilizer furrow for better sowing quality. Firstly, the force analysis was implemented on the offset bulldozing plate of the furrow opener. Among them, the horizontal force balance analysis of the side deep fertilizer shovel and the sowing furrow opener was also made to design the structure of the furrow opener. The height of the retaining positioning plate and the offset bulldozing plate of the furrow opener was determined to be 160 mm, and the bottom edge spacing between the retaining positioning plate and the offset bulldozing plate was 30 mm equal to the short side width of the shovel handle, the insertion gap angle was 8°, and the inclination angle was 10.6°. Secondly, the soil disturbance was analyzed before and after the operation of the straight-oblique offset furrow opener. The straight-oblique offset furrow opener increased the soil backfill of the fertilizer furrow and seed furrow. Finally, the sliding cutting of cutting oblique edge was clarified in the motion analysis of soil particles on the offset bulldozing plate. The structural parameters of the operation performance of the furrow opener were the oblique edge sliding angle and the offset angle. A discrete element simulation model of soil-stubble-straw was established using EDEM. The three-dimensional models of stubble cutter, fertilizer shovel, and furrow opener were imported into EDEM for simulation experiments. The structural parameters of the furrow opener were optimized by a two-factor and five-level orthogonal rotation combination experiment with forward resistance, the backfill depth of the fertilizer furrow and the backfill depth of the seed furrow as experiment indexes. The optimal combination of parameters was achieved in the oblique edge sliding angle of 37° and the offset angle of 15°. A field experiment was conducted with the double disc and sharp-angle furrow openers under optimal parameters. The sowing depth variation coefficient of straight-oblique offset furrow openers was 41.12% and 19.41% lower than those of double disc and sharp angle furrow openers, respectively. The sowing lateral variation coefficients decreased by 39.00% and 28.41%, respectively. The forward resistance was reduced by 7.26% and 28.20%, respectively. The backfill depth of the fertilizer furrow increased by 9.47% and 13.68%, respectively after optimization. The backfill depth of seed furrow increased by 33.33% and 7.14% respectively. The furrow opener reduced the forward resistance, while improving the soil backfill of the fertilizer furrow and seed furrow for the sowing depth uniformity and sowing lateral consistency. The finding can provide a strong reference for the design of the seeding furrow opener. [ABSTRACT FROM AUTHOR]
