Henrietta Lacks probably didn’t seem so immortal to doctors when she was first diagnosed at Johns Hopkins Hospital in 1951. The poor 31-year-old African American woman — the subject of a best-selling book, “The Immortal Life of Henrietta Lacks,” and a new HBO movie starring Oprah Winfrey — was suffering from cervical cancer.    “It was generally a death sentence then,” said Patricia Eifel, a professor of radiation oncology at the  MD Anderson Center in Houston.

米歇尔·罗伯兹（Michelle Roberts）BBC健康事物编辑2021年10月5日 美国科学家在第一位患者身上所作试验取得令人满意的结果后相信，一种植入大脑的电子装置可以侦测和治疗严重抑郁症。 这名患者名叫莎拉，36岁，之前患有严重抑郁症。接受大脑电子植入装置治疗一年多后，她说，生活得到彻底改变。 莎拉大脑的电子植入物像一个火柴盒般大小，永远处于开机状态，但只有当它感觉有需要时才发送脉冲信号。 这项研究结果发表在《自然医学》杂志上。 美国加利福尼亚大学旧金山分校的研究人员强调，现在就说它能否可以帮助治疗像莎拉这样有抑郁顽疾的其他患者还为时过早，但他们充满信心，并计划进行更多的试验。 抑郁症电路图？ 莎拉是接受这一试验疗法的第一人。之前她曾吃过抗抑郁药物，最近几年接受电痉挛疗法（electroconvulsive therapy），但都以失败告终。 通过外科手术在大脑植入电子装置听起来有些吓人，但莎拉说，有望获得“任何一点解脱”都要好过她所经历的黑暗痛苦。 “我尝试了所有治疗方法。我每一天都饱受磨难，几乎很少活动，或是做任何事，”莎拉说。 医生需要在莎拉头骨上钻两个小孔，安装可以监视和刺激她大脑的线路。装有电池和脉冲发射器的小盒子则被嵌在她头皮和头发下的颅骨中。 手术需要一整天，而且需要全身麻醉，莎拉在整个过程中毫无知觉。莎拉说，手术醒来后有一种欣快的感觉。 她说，“电子装置第一次开启时，我的生活立即出现好转。生活又变好了。”“几周之内，自杀念头就消失了。” 一年后，莎拉仍然感觉良好，没有副作用。 莎拉表示，大脑电子装置让她摆脱抑郁症，并让她处于最佳状态，重建生活。 她说，植入的装置发射信号时自己感觉不到。但是，“在信号停止后的15分钟内能有所察觉，因为这时会感觉非常清醒，或者感到一种正能量。” 工作原理 研究人员斯坎戈斯博士也是加州大学的精神病学家。她说，这一创新疗法之所以成为现实可能是因为他们找到了莎拉大脑中的“抑郁回路”。 斯坎戈斯博士表示，他们找到了一个叫腹侧纹状体（ventral striatum）的位置， 通过不断刺激该部位可以消除莎拉的抑郁感。 “我们还在大脑杏仁核内发现一个大脑活动区，这一区域可以预测她的症状何时最严重，” 斯坎戈斯博士说。 科学家们说，他们需要对这一疗法进行更多研究，以确定它是否能帮助更多的严重抑郁症、或许还有其他一些病症的患者。 个性化治疗 斯坎戈斯博士在试验中已经招募了2名患者，并希望再招募9人。她表示，需要观察不同患者大脑回路有何差异，然后多次重复试验。 她说，“我们需要观察个体生化标志物或大脑回路是否会随着治疗继续而发生变化。由于她的抑郁如此严重，我们一开始根本不知道能否治疗她。” 因此，斯坎戈斯博士表示，从这一意义上来说，他们感到非常兴奋。因为这是目前这一领域非常需要的。 为莎拉装置电子设备的神经外科医生张复伦（Edward Chang）强调，需要说明的是，这并非是要证明这种方法的疗效。 他说，“这只是第一次展示在某人身上有效而已。在这一领域我们还有许多工作要做，才能证实它是否可以成为一个比较持久的治疗选项。” 英国伦敦大学学院的神经科学专家罗伊瑟教授表示，虽然这种高度创伤性外科手术只应该用于那些患有顽疾的重症患者 ，但刺激大脑的个性化特点代表着“向前迈出了令人兴奋的一步”。 罗伊瑟教授表示，如果在其他病人身上进行试验，很可能需要记录、刺激不同部位，因为不同症状的精确脑部回路可能会因人而异。 他说，“由于只是一名患者，而且没有对照病例，因此，这些令人兴奋的结果是否能在临床试验中成立还有待观察。” ncG1vNJzZmivp6x7o67CZ5qopV%2BvtbC6xrCcp2ejnrqxe9KcoJ6mk5p6doSXaWlpamI%3D

Multiple dust devils and fire whirls formed in the Burning Man bonfire last weekend. They grew to over 100 feet tall and drifted across the Black Rock Desert with rapidly whirling winds. They picked up debris and plowed through the burners downwind of the fire. Over and over the fire birthed these dust devils — I counted at least a dozen in one video — and some of them were actually still on fire as they peeled away from the flames.
