    الوصف: The activation of hepatic stellate cells (HSCs) is a key event during the progression of liver fibrosis (LF). We have previously indicated that NLRP3 inflammasome plays a crucial role in arsenic-induced HSCs activation. However, the mechanism of cascade responses between NLRP3 inflammasome and HSCs activation is unclear. Here, we showed that the transcription and protein level of Hsp47 was upregulated after 4 μM arsenic treatment, both in vivo and in vitro. Additionally, arsenic-induced HSCs activation was remarkably alleviated by the interference of Hsp47. Furthermore, blockage of NLRP3 significantly mitigated the activation of the NLRP3 inflammasome and decreased the expression of Hsp47, thereby attenuating the arsenic-induced HSCs activation. However, the ablation of Hsp47 did not affect the activation of the NLRP3 inflammasome. Notably, the protein-protein interaction between NLRP3 and Hsp47 was observed both in vivo and in vitro, and the target amino acid sequences were further identified. In summary, the present study indicated that NaAsO

    الوصف: Hepatic insulin resistance (IR) is the primary pathology of type 2 diabetes (T2D). The role of the NOD-like receptor protein 3 (NLRP3) inflammasome in arsenic-induced hepatic IR has been previously demonstrated. However, the mechanism of the arsenic-induced activation of the NLRP3 inflammasome is still unclear. Here, we demonstrate that NaAsO

    الوصف: As an environmental toxicant, arsenic exposure may cause insulin resistance (IR). Previous studies have shown that pyroptosis plays an important role in the occurrence and development of IR. Although gasdermin D (GSDMD) functions as an executor of pyroptosis, the relationship between GSDMD-mediated pyroptosis and hepatic IR remains unclear. Here, we observed that sodium arsenite (NaAsO

    الوصف: Inhalation of medical drug particles through human airway is widely utilized for the remedy of lung diseases. Due to the complexities of airway morphology, flow turbulence and particle deposition, the drug delivery efficiency to the morbid region of lung is always unsatisfactory. In this research, a 3D anatomically accurate human airway model from oral cavity to lung is reconstructed, and the large eddy simulation-discrete phase model (LES-DPM) is adopted to simulate the airway flow and drug particles transport. To improve the particle delivery to the targeted region of the left lung, a magnetic drug targeting (MDT) system is established. It is found that the LES-DPM in conjunction with MDT system is an effective tool to study airway flow patterns and magnetic particle deposition features. Moreover, the magnetic source layout, magnetic particle size and magnetic field intensity all have significant impacts on the particle deposition efficiency in the left lung. Optimal combination factors for drug particle delivery results are successfully achieved. The total deposition efficiency of magnetic particles in the left lung can be increased to more than 5 times. This work not only could provide a better understanding of air-particle dynamics, but also could contribute toward improved strategies for more efficient drug delivery in the realistic human lungs.

    الوصف: With the speeding-up of the Chinese economy, China is experiencing the rapid urbanization. Meanwhile, the Chinese rural education is also developing, which has made great progress in recent years. However, inequity between urban and rural education prevalently exists in China, and the unbalanced development of urban and rural areas still influences the Chinese education. However, the Chinese have taken a lot of measures to enhance the quality of rural education, such as ad hoc post policy, the school meal program, and so on. In addition, the rural schools have also launched some activities to develop the students and to serve the society.

    الوصف: The novice teacher's training is playing an important role in the education reform. In Xi'an Gaoxin No.1 Primary School, the school leaders host a pilot way of training the new teachers. The new teacher training of the school is special and meaningful. The training not only includes professional skill, student management, and teacher's ethics, but also includes art, calligraphy, reading, and so on. The authors invested 73 teachers (male=9, female=64) who had got the job one year ago. After one year's training, 73.97% of novice teachers express full agreement about the training and are quite satisfied with the training. Comparing with the beginning of the career, the novice teachers have improved the teaching abilities a lot.
