Nowadays, all countries in the world regard creativity as one of the core abilities of talent competition. The core of cultivating creative talents is to carry out creative education. Early childhood is the enlightenment period of creative education. During this period, children have not formed a set of thinking, protecting and stimulating their imagination, curiosity and desire to explore. Because music education plays a unique role in fostering children’s creativity, it is beneficial to the development of children’s creative thinking and the formation of creative personality. The purpose of this article is to analyse and study the characteristics of children’s early thinking development, innovative music teaching concepts and teaching methods, and to develop children’s action thinking, image thinking, abstract thinking and creative thinking at this stage through innovative rhythmic activities and Orff teaching, focusing on the specific period of children. It can promote their brain more active and more comprehensive. Through the research, it is found that the professional quality and innovation of preschool teachers play an important role in the development of children’s creative thinking, and rhythmic activities and Orff music teaching method are suitable for the development of children’s creative thinking, and have a larger space for exploration.

This study aims to deliver a systematic review and meta-analysis to scrutinize the tolerability of different doses of oliceridine in acute pain patients. A comprehensive search was carried out in essential databases (PubMed, Embase, Cochrane Library, and Web of Science) for relevant studies up to the most recent available date.We included Randomized Controlled Trials (RCTs) that compared oliceridine with other interventions in acute pain management. Patients received an equi-analgesic dose of oliceridine relative to morphine, ensuring comparable Sum of Pain Intensity Differences (SPID-48 or SPID-24) or mean pain score reductions across groups. The initial loading dose was 1.5 mg for oliceridine and 4 mg for morphine, followed by demand doses via patient-controlled analgesia (PCA). For oliceridine, the demand doses were 0.1, 0.35, or 0.5 mg, while for morphine, it was 1 mg.Utilizing the Review Manager 5.4, data on nausea, vomiting, sedation, dizziness, pruritus, and hypoxemia were assembled and evaluated.We conducted sensitivity analyses to confirm the robustness of our findings. The preliminary search discovered 710 potential studies. Having gone through a careful screening process, a total of 7 RCTs met our inclusion benchmarks. Five distinct publications analyzed postoperative nausea and vomiting (PONV). According to our meta-analysis findings, patients assigned to the oliceridine group experienced a notably lower rate of postoperative nausea (PON) and postoperative vomiting (POV) compared to the morphine group (PON: RR = 0.55, 95% CI 0.41–0.74, P  < 0.001; POV: RR = 0.36, 95% CI 0.28–0.47, P  < 0.001). Data from 4 documents examined sedation and dizziness. Our findings demonstrate that oliceridine recipients had a significant decline in the incidence of both sedation and dizziness (sedation: RR = 0.64, 95% CI 0.45–0.91, P  = 0.01; dizziness: RR = 0.71, 95% CI 0.57–0.88, P  = 0.002).Moreover, the oliceridine group recorded a lower incident of hypoxemia showcasing a favorable safety profile (RR = 0.52, 95% CI 0.41–0.65, P  < 0.001).Sensitivity analyses confirmed the robustness of these findings. The systematic review and meta-analysis reveal that oliceridine is a well-tolerated and safe intravenous analgesic for acute pain patients, often reducing the incidence of adverse events in comparison to morphine.

Sepsis-induced acute lung injury (ALI) is a major cause of death among patients with sepsis in intensive care units. By analyzing a model of sepsis-induced ALI using lipopolysaccharide (LPS) and cecal ligation and puncture (CLP), treatment methods and strategies to protect against ALI were discussed, which could provide an experimental basis for the clinical treatment of sepsis-induced ALI. Recent studies have found that an imbalance in autophagy, ferroptosis, and pyroptosis is a key mechanism that triggers sepsis-induced ALI, and regulating these death mechanisms can improve lung injuries caused by LPS or CLP. This article summarized and reviewed the mechanisms and regulatory networks of autophagy, ferroptosis, and pyroptosis and their important roles in the process of LPS/CLP-induced ALI in sepsis, discusses the possible targeted drugs of the above mechanisms and their effects, describes their dilemma and prospects, and provides new perspectives for the future treatment of sepsis-induced ALI.

The precision of workpiece machining is critically influenced by the geometric errors in the kinematics of grind robots, which directly affect their absolute positioning accuracy. To tackle this challenge, this paper introduces a logistic-tent chaotic mapping Levenberg Marquardt algorithm designed to accurately identify and compensate for this geometric error. the approach begins with the construction of a forward kinematic model and an error model specific to the robot. Then the algorithm is adopted to identify and compensate for the geometric error. The method establishes a mapping interval around the initial candidate solutions derived from iterative applications of the Levenberg Marquardt algorithm. Within this interval, the logistic-tent chaotic mapping method generates a diverse set of candidate solutions. These candidates are evaluated based on their fitness values, with the optimal solution selected for subsequent iterations. Empirical compensation experiments have validated the proposed method's precision and effectiveness, demonstrating a 6% increase in compensation accuracy and a 47.68% improvement in efficiency compared to existing state-of-the-art approaches. This process not only minimizes the truncation error inherent in the Levenberg Marquardt algorithm but also significantly enhances solution efficiency. Moreover, simulation experiments on grind processes further validate the method's ability to significantly improve the quality of workpiece machining.

Recombinant human interferon Alfa-2b vaginal suppository is a gynecological preparation mainly made of interferon, commonly used to treat diseases related to viral infections such as cervical erosion. As a recombinant protein drug, it is important to pay attention to the possibility of modifications that may lower the quality of the drug during the production process. The aim of this study is to evaluate the pharmacokinetic (PK) and pharmacodynamic (PD) characteristics of this product in Chinese rhesus macaque after purification process changes, and to demonstrate that there is no difference in the biological activity of recombinant human interferon Alfa-2b vaginal suppository stock solution before and after process changes. There are 12 test animals: Chinese rhesus macaques who received a two-group crossover design and were subcutaneously injected with the same active dose of 500,000 IU/kg around the navel in the abdomen. According to maximum concentration (C max ) and time of maximum concentration (T max ) within non-parametric test ( P  > 0.05), geometric mean ratio of PK parameter C max for the drugs after purification process changes (sample S) compared to the before purification process changes one (sample R) was 97.09%, with a 90% confidence interval (CI) of 87.39–107.87%. The geometric mean ratio C max of serum Beta2-microglobulin (PD max ) for PD index is 100.07%, with a 90% CI of 97.16–103.07%; Geometric mean ratio of AUEC 0 − t is 98.91%, with a 90% CI of 96.53–101.34%. The geometric mean of the PD index, neopterin PD max , is 97.75%, with a 90% CI of 92.53–103.25%; Geometric mean of AUEC 0 − t is 105.59%, with a 90% CI ranging from 97.22 to 114.68%. The important parameters of PK/PD meet the equivalence requirements, and biological activity of the recombinant human interferon Alfa-2b vaginal suppository stock solution after purification process change is no different from before the change. Under the same active dose administration conditions, the same biological effects were produced, achieving the same effect as before the change.

The slowdown of China’s economic growth in the middle-income stage has caused widespread concerns. Based on the analysis of economic structures to explain the downward trend of economic growth, this study expanded the Solow-Swan model to investigate the structural imbalances and evaluated their impacts during the structural transformation in different stages and regions on the economic downturn. Considering the processes of production, distribution, and consumption, six structures were chosen for national and prefecture-levels in China from 1997 to 2017, including sectoral structure, population structure, investment and consumption structure, import-export structure, urban-rural income structure, and financial structure. The study found that China’s comprehensive economic structure was significantly different before and after the middle-income stage, and structural bonus tended to decline. Structural imbalance presented a U-shaped pattern of decreasing first and then increasing, and the impact on economic growth underwent stages of suppression-promotion-suppression. There was a significant difference in the imbalance of six sub-structures and their impacts; furthermore, in the four regions of east, center, west, and northeast the observations were very different. Taken together, the imbalance of economic structure and economic transformation coexisted, and the economic growth slowed down. Based on the experiences from China, this paper provided some evidence for promoting structural optimization and transformation.

Intracerebral hemorrhage (ICH) is a most serious type of hemorrhagic stroke with a continuously rising incidence globally, without effective cure available. The underlying mechanisms driving brain injury are complex and include inflammation, oxidative stress, glutamate excitotoxicity, membrane damage, lipid peroxidation, ferroptosis and other cellular death modes. Hematoma clearance is the key to limit brain damage and foster the recovery process. The quest for effective ICH remedies is continuing and strategically evolving with the expansion of knowledge and understanding of target mechanisms and novel lead compounds. In this study, we have investigated the effects of cinnamaldehyde after ICH as an individual treatment as well as in combination with deferoxamine. The autologous blood injection model was employed using C57BL/6 mice. Following 2 h of ICH induction, animals received IP injection once per day for three days; normal saline in ICH model group, cinnamaldehyde, deferoxamine, and combined cinnamaldehyde and deferoxamine in respective groups. Measurement of neurobehavioral scoring, markers of inflammation NFкB, TNFα, IL-1, IL6, iNOS; oxidative stress and ferroptosis GSH, TBARS, glutamate, choline containing phospholipids, GPX4, SLC7A11, SLC40A1, ACSL4; and hematoma clearance hemoglobin, haptoglobin, hemopexin, zonulin, CD163, LRP1, HO1, CD36, CD206, were investigated using ELISA, PCR, and western blot. Immunofluorescence for NeuN/SLC40A1, GFAP/GPX4, NeuN/HO1, Iba1/HO1 was also performed. We have found that cinnamaldehyde possess anti-inflammatory, antioxidant, anti-ferroptotic and hematoma limiting properties that were comparable to those obtained with deferoxamine. However, combination of cinnamaldehyde and deferoxamine demonstrated remarkable effectiveness in restoration of these parameters indicating their synergistic effect in ICH model.

Due to the inherent disorder and fluidity of water, precise machining of water through laser cutting are challenging. Herein we report a strategy that realizes the laser cutting machining of water through constructing hydrophobic silica nanoparticle-encased water pancakes with sub-millimeter depth. Through theoretical analysis, numerical simulation, and experimental studies, the developed process of nanoparticle-encased water pancake laser cutting and the parameters that affect cutting accuracy are verified and elucidated. We demonstrate that laser-fabricated water patterns can form diverse self-supporting chips (SSCs) with openness, transparency, breathability, liquid morphology, and liquid flow control properties. Applications of laser-fabricated SSCs to various fields, including chemical synthesis, biochemical sensing, liquid metal manipulation, patterned hydrogel synthesis, and drug screening, are also conceptually demonstrated. This work provides a strategy for precisely machining water using laser cutting, addressing existing laser machining challenges and holding significance for widespread fields involving fluid patterning and flow control in biological, chemical, materials and biomedical research. “Due to the inherent disorder and fluidity of water, machining of water through laser cutting is challenging. Here, authors report a strategy through laser cutting to realize the machining of nanoparticle encased water pancakes with the depth of water at sub-millimeter level.”

Transplantation of hematopoietic stem cells (HSCs) with a naturally occurring CCR5 mutation confers a loss of detectable HIV-1 in the patient, making ablation of the CCR5 gene in HSCs an ideal therapy for an HIV-1 cure. Although CCR5 disruption has been attempted in CD4+ T cells and hematopoietic stem/progenitor cells (HSPCs), efficient gene editing with high specificity and long-term therapeutic potential remains a major challenge for clinical translation. Here, we established a CRISPR/Cas9 gene editing system in human CD34+ HSPCs and achieved efficient CCR5 ablation evaluated in long-term reconstituted NOD/Prkdcscid/IL-2Rγnull mice. The CCR5 disruption efficiency in our system remained robust in secondary transplanted repopulating hematopoietic cells. More importantly, an HIV-1 resistance effect was observed as indicated by significant reduction of virus titration and enrichment of human CD4+ T cells. Hence, we successfully established a CRISPR/Cas9 mediated CCR5 ablating system in long-term HSCs, which confers HIV-1 resistance in vivo. Our study provides evidence for translating CCR5 gene-edited HSC transplantation for an HIV cure to the clinic. [Display omitted] Xu et al. have used the CRISPR/Cas9 system to achieve CCR5 gene disruption in human hematopoietic stem/progenitor cells (HSPCs). The gene-ablated HSPCs could reconstitute in vivo long term and resist HIV-1 infection. This study provides evidence of CCR5 gene ablation in HSCs as a promising therapy for HIV-1.

High throughput phenotyping (HTP) for wheat (Triticum aestivum L.) stay green (SG) is expected in field breeding as SG is a beneficial phenotype for wheat high yield and environment adaptability. The RGB and multispectral imaging based on the unmanned aerial vehicle (UAV) are widely popular multi-purpose HTP platforms for crops in the field. The purpose of this study was to compare the potential of UAV RGB and multispectral images (MSI) in SG phenotyping of diversified wheat germplasm. The multi-temporal images of 450 samples (406 wheat genotypes) were obtained and the color indices (CIs) from RGB and MSI and spectral indices (SIs) from MSI were extracted, respectively. The four indices (CIs in RGB, CIs in MSI, SIs in MSI, and CIs + SIs in MSI) were used to detect four SG stages, respectively, by machine learning classifiers. Then, all indices’ dynamics were analyzed and the indices that varied monotonously and significantly were chosen to calculate wheat temporal stay green rates (SGR) to quantify the SG in diverse genotypes. The correlations between indices’ SGR and wheat yield were assessed and the dynamics of some indices’ SGR with different yield correlations were tracked in three visual observed SG grades samples. In SG stage detection, classifiers best average accuracy reached 93.20–98.60% and 93.80–98.80% in train and test set, respectively, and the SIs containing red edge or near-infrared band were more effective than the CIs calculated only by visible bands. Indices’ temporal SGR could quantify SG changes on a population level, but showed some differences in the correlation with yield and in tracking visual SG grades samples. In SIs, the SGR of Normalized Difference Red-edge Index (NDRE), Red-edge Chlorophyll Index (CIRE), and Normalized Difference Vegetation Index (NDVI) in MSI showed high correlations with yield and could track visual SG grades at an earlier stage of grain filling. In CIs, the SGR of Normalized Green Red Difference Index (NGRDI), the Green Leaf Index (GLI) in RGB and MSI showed low correlations with yield and could only track visual SG grades at late grain filling stage and that of Norm Red (NormR) in RGB images failed to track visual SG grades. This study preliminarily confirms the MSI is more available and reliable than RGB in phenotyping for wheat SG. The index-based SGR in this study could act as HTP reference solutions for SG in diversified wheat genotypes.
