    Abstract: Sugarcane stem node detection is one of the key functions of a small intelligent sugarcane harvesting robot, but the accuracy of sugarcane stem node detection is severely degraded in complex field environments when the sugarcane is in the shadow of confusing backgrounds and other objects. Methods To address the problem of low accuracy of sugarcane arise node detection in complex environments, this paper proposes an improved sugarcane stem node detection model based on YOLOv7. First, the SimAM (A Simple Parameter-Free Attention Module for Convolutional Neural Networks) attention mechanism is added to solve the problem of feature loss due to the loss of image global context information in the convolution process, which improves the detection accuracy of the model in the case of image blurring; Second, the Deformable convolution Network is used to replace some of the traditional convolution layers in the original YOLOv7. Finally, a new bounding box regression loss function WIoU Loss is introduced to solve the problem of unbalanced sample quality, improve the model robustness and generalization ability, and accelerate the convergence speed of the network. Results The experimental results show that the mAP of the improved algorithm model is 94.53% and the F1 value is 92.41, which are 3.43% and 2.21 respectively compared with the YOLOv7 model, and compared with the mAP of the SOTA method which is 94.1%, an improvement of 0.43% is achieved, which effectively improves the detection performance of the target detection model. Discussion This study provides a theoretical basis and technical support for the development of a small intelligent sugarcane harvesting robot, and may also provide a reference for the detection of other types of crops in similar environments.

    Abstract: This study determined the inhibitory activity of oligopeptides against angiotensin-converting enzyme (ACE) and pancreatic lipase through in vitro tests, molecular docking, and enzyme inhibition. The results showed that the IC 50 of GLLGY, HWP, and VYGF for ACE inhibition was 1 mg/mL, and the IC 50 of HWP for pancreatic lipase was 3.95 mg/mL. Molecular docking revealed that the binding energies between GLLGY, HWP, and VYGF and ACE were –9.0, –8.4, and –9.2 kcal/mol, respectively. The binding free energy between HWP and pancreatic lipase was –7.3 kcal/mol. GLLGY, HWP, and VYGF inhibited ACE compentitively. HWP inhibited pancreatic lipase through non-competition. in vitro simulated gastrointestinal digestion, the three oligopeptides still had inhibitory activity and low toxicity. The results revealed that the peptides GLLGY, HWP, and VYGF may be suitable candidates for further research on ACE inhibition, and HWP may be a suitable candidate for studying pancreatic lipase inhibition.

    Abstract: China is steeped in a long history and splendid culture, where minority cultures add brilliance to traditional Chinese culture like bright pearls. For example, the culture of the Yi people showcases the richness of Chinese minority cultures, and at the same time, it is of special significance to traditional culture. From the perspective of the three-color culture (referring to black, red, and yellow) peculiar to the Yi people, this paper will analyze the features of the three-color culture and the colors, and study the unique aesthetic ideas of the three-color culture in the long history to demonstrate the Yi people’s color-favored customs and connotations of traditional culture.This paper consists of two important parts. First, it describes the traditional color culture of the Yi people and the features of these colors. The Yi people have a long history of the reverence for colors and a deep cultural heritage, which is a product of cultural accumulation. The Yi people have their unique understanding of colors, which comes from their life and nature. The reverence for and the worship of black, red, and yellow also has a long history and reasons. The features of these three colors unique to the Yi people reflect the culture of the Yi people and their emotions, embodying the unique color culture of the Yi people. Second, it studies the aesthetic ideas of the color culture of the Yi people, which is the focus of this paper. It analyzes and studies the aesthetic principles, styles, and ideas of the color culture of the Yi people deeply through centering on their costumes, lacquerware, and unique dance poems. With unique styles, the costumes of the Yi people are varied in colors, mainly using black, red, and yellow. Such use of colors creates a stark contrast, highlighting the characteristics of the Yi ethnic group’s costumes and its ethnic features. The lacquerware of the Yi people is an expression of their unique aesthetic understanding of the use of three colors and the area of colors used. The color rhythms demonstrated with the help of a symmetric and harmonious application of colors is an important feature of the Yi ethnic group’s lacquerware. The dance poem is a unique way to display the three-color culture of the Yi ethnic group. The black, red, and yellow are interpreted through three chapters by using the simplest colors to match the dance, creating a stark contrast that not only demonstrates the unique color culture of the Yi people, but also highlights the characteristics of the Yi people and their aesthetic ideas. Therefore, the research on the Yi ethnic group’s color culture starts from three colors including black, red, and yellow, and explores the history of the culture as well as the characteristics of the Yi people, aiming to help people deepen their understanding of the color culture and the color-favored psychology of the Yi nationality, and the unique aesthetic ideas of this group. And this can further help us identify the special value of the Yi ethnic group’s color culture and promote the spreading of the color culture of ethnic minorities.In the context of the times, the colors used by ethnic minorities all demonstrate their own ethnic characteristics, and it relates to people’s life and emotions, and nature. Therefore, it can be said that the choice of colors not only reflects one’s aesthetic appreciation but also embodies the desire for life and a recognized culture.

    Abstract: Although tirofiban and endovascular thrombectomy have been widely used in the treatment of acute ischemic stroke (AIS) patients, the effectiveness of their combined application remains a subject of debate. This study aimed to assess the efficacy and safety of tirofiban in direct thrombectomy for AIS with anterior circulation vessel occlusion. METHODS A total of 204 patients undergoing direct thrombectomy between January 2020 and December 2021 for AIS with anterior circulation vessel occlusion from four hospitals were included in this study. Patients at high risk of reocclusion with severe atherosclerosis, those who achieved successful recanalization for ≥ 3 stent retriever passes, or those who underwent emergency stenting or balloon angioplasty for severe residual stenosis were treated with tirofiban. Following a low-dose intra-arterial bolus (0.25–1 mg) immediately after endovascular treatment, tirofiban was administered continuously through intravenous infusion (0.1 μg/kg/min) for 12–24 hours. The primary efficacy outcome was evaluated using the 90-day modified Rankin Scale score. The safety outcome was assessed using symptomatic intracerebral hemorrhage (sICH) and mortality rates. RESULTS The tirofiban group and nontirofiban group each included 102 patients. The favorable outcome rate in the tirofiban group was significantly higher than that in the nontirofiban group (53.9% vs 35.3%, p = 0.007). However, the sICH and 90-day mortality rates were lower in the tirofiban group, despite a lack of statistical significance (sICH: 15.7% vs 16.7%, p = 0.849; 90-day mortality: 16.67% vs 24.51%, p = 0.166). Finally, it was found that older patients ( 〉 72 years), male patients, patients with admission National Institutes of Health Stroke Scale scores 〉 14, patients with a time from onset to reperfusion 〉 327 minutes, and patients with a medical history of diabetes tend to benefit from tirofiban treatment. CONCLUSIONS This study suggests that tirofiban combined with direct thrombectomy improves functional outcomes of AIS and reduces the 90-day mortality rate. Therefore, it could be considered as a suitable treatment option for AIS patients with anterior circulation vessel occlusion.

    Abstract: This review systematically examines gender differences in hepatocellular carcinoma (HCC), identifying the influence of sex hormones, genetic variance, and environmental factors on the disease’s epidemiology and treatment outcomes. Recognizing the liver as a sexually dimorphic organ, we highlight how gender-specific risk factors, such as alcohol consumption and obesity, contribute differently to hepatocarcinogenesis in men and women. We explore molecular mechanisms, including the differential expression of androgen and estrogen receptors, which mediate diverse pathways in tumor biology such as cell proliferation, apoptosis, and DNA repair. Our analysis underscores the critical need for gender-specific research in liver cancer, from molecular studies to clinical trials, to improve diagnostic accuracy and therapeutic effectiveness. By incorporating a gender perspective into all facets of liver cancer research, we advocate for a more precise and personalized approach to cancer treatment that acknowledges gender as a significant factor in both the progression of HCC and its response to treatment. This review aims to foster a deeper understanding of the biological and molecular bases of gender differences in HCC and to promote the development of tailored interventions that enhance outcomes for all patients.

    Abstract: To develop a prognostic prediction model of endovascular treatment (EVT) for acute ischemic stroke (AIS) induced by large-vessel occlusion (LVO), this study applied machine learning classification model light gradient boosting machine (LightGBM) to construct a unique prediction model. Methods A total of 973 patients were enrolled, primary outcome was assessed with modified Rankin scale (mRS) at 90 days, and favorable outcome was defined using mRS 0–2 scores. Besides, LightGBM algorithm and logistic regression (LR) were used to construct a prediction model. Then, a prediction scale was further established and verified by both internal data and other external data. Results A total of 20 presurgical variables were analyzed using LR and LightGBM. The results of LightGBM algorithm indicated that the accuracy and precision of the prediction model were 73.77 and 73.16%, respectively. The area under the curve (AUC) was 0.824. Furthermore, the top 5 variables suggesting unfavorable outcomes were namely admitting blood glucose levels, age, onset to EVT time, onset to hospital time, and National Institutes of Health Stroke Scale (NIHSS) scores (importance = 130.9, 102.6, 96.5, 89.5 and 84.4, respectively). According to AUC, we established the key cutoff points and constructed prediction scale based on their respective weightings. Then, the established prediction scale was verified in raw and external data and the sensitivity was 80.4 and 83.5%, respectively. Finally, scores & gt;3 demonstrated better accuracy in predicting unfavorable outcomes. Conclusion Presurgical prediction scale is feasible and accurate in identifying unfavorable outcomes of AIS after EVT.

    Abstract: The plant factory is a form of controlled environment agriculture (CEA) which is offers a promising solution to the problem of food security worldwide. Plant growth parameters need to be acquired for process control and yield estimation in plant factories. In this paper, we propose a fast and non-destructive framework for extracting growth parameters. Firstly, ToF camera (Microsoft Kinect V2) is used to obtain the point cloud from the top view, and then the lettuce point cloud is separated. According to the growth characteristics of lettuce, a geometric method is proposed to complete the incomplete lettuce point cloud. The treated point cloud has a high linear correlation with the actual plant height ( R 2 = 0.961), leaf area ( R 2 = 0.964), and fresh weight ( R 2 = 0.911) with a significant improvement compared to untreated point cloud. The result suggests our proposed point cloud completion method have has the potential to tackle the problem of obtaining the plant growth parameters from a single 3D view with occlusion.
