一 | 这种新的分子癌症治疗方法依赖于一种特定的分子，它可以寻找围绕癌细胞的酸性环境。 Chinese Foreign Minister Wang Yi said here on Thursday that he hopes South Korea will firmly pursue a friendly policy toward China and take the 35th anniversary of the establishment of diplomatic relations between the two countries next year as an opportunity to make greater progress in the China-South Korea strategic cooperative partnership. Wang, also a member of the Political Bureau of the Communist Party of China Central Committee, made the remarks when meeting with South Korean President Lee Jae Myung in Seoul. Wang said the comprehensive restoration of China-South Korea relations and positive progress made since the beginning of this year have demonstrated that a rational, pragmatic and positive policy toward China fully serves South Korea's interests and is in keeping with the trend of the times. As an important force for maintaining world peace, China consistently advocates the political settlement of international and regional conflicts through dialogue, Wang said, adding that China is also a major stabilizing force, providing valuable certainty for the world. Wang also noted that China is ready to share development opportunities with all countries, especially its neighbors. Amid growing global economic fragmentation and rising trade protectionism, Wang pointed out that China and South Korea should set an example by concluding the second phase of Free Trade Agreement (FTA) negotiations at an early date to promote regional economic integration and universally beneficial and inclusive economic globalization. For his part, the South Korean president said that he was glad to see China-South Korea relations improving and developing rapidly, with strong growth momentum in economic and trade cooperation. While highlighting that people-to-people exchanges between the two countries are expected to exceed 10 million this year, Lee said that South Korean public perceptions of China are improving and there are growing expectations for strengthening comprehensive cooperation with China. Amid the current international situation, Lee said that stronger strategic cooperation between South Korea and China serves the fundamental interests of both countries and is important for regional peace and stability. South Korea and China should become mutually dependent and mutually beneficial partners with complementary strengths, Lee said, adding that the two countries need each other in areas such as economy, trade and security. Lee said he looks forward to visiting China's Shenzhen City in November for the 2026 APEC Economic Leaders' Meeting, calling it an important opportunity to work with China to advance the South Korea-China strategic cooperative partnership to a new level. During the visit, Wang also met with South Korean Foreign Minister Cho Hyun and Wi Sung-lac, South Korea's top presidential national security advisor. 。但是，为了使细胞有足够的酸性，它们不能是“冷”的肿瘤，这种肿瘤几乎没有免疫活性。这就是被称为STING激动剂的药物发挥作用的地方。这些药物使肿瘤“燃烧”起来，允许免疫系统对其作出反应。然而，找到"冷"癌细胞可能很困难。这就是新的分子癌症疗法发挥作用的地方。研究人员本月在《肿瘤学前沿》（Frontiers of Oncology）杂志上发表了一项关于该分子的研究。根据该研究，该分子被称为pH值低的插入肽（pHLIP），它被吸引到酸性环境。通过使用该分子引导药物到肿瘤和癌细胞，他们能够将它们踢出"寒冷"的肿瘤范围，推动免疫系统进行反击。然后，他们可以使用免疫检查点抑制剂来有效地移除使免疫系统不至于用力过猛的自然刹车。这种分子癌症治疗方法让免疫系统更长时间地对抗癌症。这是一个双重的系统，基本上允许研究人员准确地引导药物到它们需要的地方。近年来，我们已经看到越来越多像这种新的分子癌症治疗方法这样的靶向选择出现了。一种针对癌细胞的病毒也一直在进行，我们甚至看到研究人员在测试一种能杀死皮肤癌的凝胶。在测试分子癌症治疗方法时，研究人员将pHLIP与STING激动剂耦合在一起，然后对20只患有结肠直肠肿瘤的小鼠进行治疗。他们发现，在一次注射后，18只小鼠的肿瘤在几天内完全消失。在另一组有较大肿瘤的小鼠中，他们看到接受治疗的10只小鼠中有7只肿瘤消失了。
