Objective:To explore the effect of low-frequency magnetic stimulation at Shenmen(HT 7)acupoint on blood oxygen levels in the prefrontal cortex of healthy subjects.Methods:Functional near-infrared spectroscopy(fNIRS)technology was used to collect real-time data of oxygenated hemoglobin(oxy-Hb)in the prefrontal cortex of 16 healthy subjects at resting state and low-frequency magnetic stimulation of Shenmen.The mean and integral values of blood oxygen concentration were analyzed.Results:Compared with the resting state,the mean and integral values of blood oxygen concentration decreased during the task period,recovery period,and the whole process in the magnetic stimulation of Shenmen acupoint(P＜0.05).In particular,the difference was statistically significant in the recovery period(P＜0.01).Conclusions:The prefrontal cortex was widely activated and produced an immediate effect by reducing the local blood oxygen concentration at low-frequency magnetic stimulation of Shenmen acupoint,which verifies the sedative effect of Shenmen acupoint.

近距离放射治疗(brachytherapy,BT),包括高剂量率BT(high-dose-rate BT,HDR-BT)和低剂量率BT(low-dose-rate BT,LDR-BT),不仅能控制局部病灶,还能诱发免疫原性肿瘤细胞死亡,通过抗原交叉递呈及T淋巴细胞的活化,激活机体抗肿瘤免疫效应.本文就BT诱导肿瘤细胞的死亡和免疫性抗原的释放、促进树突状细胞(dendritic cells,DCs)和T细胞的活化、调节淋巴细胞亚群,进而诱发的抗肿瘤免疫效应进行综述.
胃癌在我国的发病率远高于其他国家,长期以来,手术和化疗一直是胃癌患者的首选治疗方法.由于大多数患者在诊断时已经处于疾病中晚期,胃癌的预后一直不能令人满意.随着胃癌分子生物学的发展,靶向治疗作为一种新的治疗方法,成功地延长了胃癌患者的总生存期.继靶向药物抗HER2抗体曲妥珠单抗获得成功后,阻断不同关键途径的新药物相继出现.然而几乎所有患者在治疗过程中会出现一定程度耐药.全文就各国指南推荐的胃癌靶向治疗药物及耐药机制进行综述,为未来胃癌靶向治疗药物的研究提供参考.
人体肠道内寄生着约十万亿个由500～1000不同种类组成的细菌,影响着人体消化和吸收功能、抵御感染和自身免疫疾病的患病风险,还参与药物代谢过程.肺癌的发病率和死亡率快速增长,是对人类生命威胁较大的恶性肿瘤.肠道菌群可能通过代谢或免疫等途径影响肺癌的发生,同时影响肺癌对放化疗、免疫治疗等治疗方法的疗效,但不同患者获益不一.肠道菌群在恶性肿瘤的发生、发展、诊断、治疗中的作用已成为近年来的研究热点,本研究对肠道菌群和肺癌的相关性研究进展进行综述.
原发性肝癌是常见的恶性肿瘤之一.近年来,肥胖与肝癌之间的关系逐渐受到公众和流行病学家的重视.该文对全身性肥胖、脂肪分布以及成年期体重改变与肝癌发病、预后关系的流行病学研究进行了综述.首先,介绍了传统的体质指数、腰围、腰臀比等指标以及成年早期肥胖和成年期体重改变与肝癌关系之间的研究进展;其次,针对一些较新的身体成分测量手段(如双能X线吸收法、计算机断层扫描、磁共振等)在肥胖与肝癌关系中的应用进行了简要描述;最后,由于肥胖和多种代谢紊乱关系密切,因此对2型糖尿病、代谢综合征、非酒精性脂肪肝病等与原发性肝癌之间
