Cancer remains a global health challenge, necessitating effective treatments with fewer side effects. Traditional methods such as chemotherapy and surgery often have complications. Pulsed electric fields and electroporation have emerged as promising approaches to mitigate these challenges. This study presents a comprehensive overview of electroporation as an innovative tool in cancer therapy, encompassing critical elements such as pulse generators and delivery devices. Furthermore, it introduces a simplified reversible electroporation model grounded in the Hodgkin-Huxley model. This model ensures resting potential stability by regulating ionic currents. When membrane charges reach the electroporation threshold, the model swiftly increases the fraction of open pores, resulting in a rapid rise in electroporation current. Conversely, as the transmembrane potential drops below the threshold, the model gradually reduces the fraction of open pores, leading to a gradual decline in electroporation current, indicating pore resealing. This model contributes to easier modeling and implementation of reversible electroporation dynamics, providing a valuable tool for further exploration of electroporation for cancer therapy.
癌症仍然是一项全球性的健康挑战,因此需要研发副作用更少的有效治疗方法。化疗和手术等传统方法往往会引发并发症。脉冲电场和电穿孔已成为应对这些挑战的有前景的方法。本研究全面概述了电穿孔作为癌症治疗中的一种创新工具,涵盖了脉冲发生器和输送装置等关键要素。此外,它还引入了一个基于霍奇金-赫胥黎模型的简化可逆电穿孔模型。该模型通过调节离子电流来确保静息电位的稳定性。当膜电荷达到电穿孔阈值时,该模型迅速增加开孔的比例,导致电穿孔电流迅速上升。相反,当跨膜电位降至阈值以下时,该模型逐渐降低开孔的比例,导致电穿孔电流逐渐下降,表明孔重新封闭。该模型有助于更轻松地对可逆电穿孔动力学进行建模和实施,为进一步探索电穿孔用于癌症治疗提供了一个有价值的工具。
