背景抑郁症非药物治疗的疗效比较目前仍然不清楚。方法我们对一些系统性综述作了概述，回顾了随机对照试验（RCT），比较抑郁症非药物治疗的有效性和认知行为治疗（CBT）。对多个电子数据库在2016年2月之前发表的所有文献进行了检索，不限制语言。成对的评阅人进行资料纳入、数据提炼并评估偏倚的风险。在适用的时候进行了荟萃分析。结果我们收录了367项RCT，纳入了约2000名患者，进行了11种治疗，导出17项独立的头对头比较。通过标准化的量表评估，发现CBT、自然疗法、行为干预与躯体活动干预可以降低抑郁的严重程度。然而，这些非药物干预的相对疗效仍然缺乏。这些干预对临床缓解和复发的效果不清楚。CBT的发生率比抗抑郁药物更低。局限性由于证据缺乏一致性、证据不清或偏倚风险高，导致证据的质量只是低到中等，限制了我们研究结果的可信度。结论抑郁症的非药物治疗能减少抑郁症状，在轻度到重度抑郁症患者中，应当合并抗抑郁药物治疗，一同进行。对于非药物治疗的选择，应当根据患者的价值观、偏好、临床和社会因素来与患者共同作出决定。

目的转移性乳腺癌是一种异质性疾病,最常影响肝脏。记录采用90Y行放射性栓塞(Re)的经验和它对于难治性乳腺癌肝转移病人存活的效果。方法共77例患乳腺癌的女性病人进行Re。纳入标准为不能手术且化疗耐药的肝转移灶,一般情况可,有足够的剩余肝脏,没有明显的肝肺分流。病人分为两组:组1(29例)包括东方肿瘤协作组(eCOG)评分为0,肝脏受累(0～25%)且没有肝外病变(eHD);组2(23例)包括eCOG评分为1～2,肝脏受累(26%～50%)且有eHD的证据。结果共有25例病人未入选。剩余52例病人的年龄中位数为57.5年。全体的生存中位数为11.5个月,且在那些身体状况和肝功能尚可者中为高(14.3个月∶8.2个月)。根据实体瘤缓解评价标准(ReCIST),29例病人(56%)达到部分缓解(PR),此外18例(35%)病情稳定(SD),5例(10%)病情进展(PD)。讨论90YRe对于治疗乳腺癌肝转移灶是有效的。在那些患难治性疾病的病人中证实了相关生存期和令人满意的高缓解率。要点①介入放射学技术在肝脏的转移性疾病中的应用日益广泛。②90YRe对于治疗乳腺癌肝转移灶是有效的。③在病人身体状况和肝功能尚可时Re安全且可耐受性高。

小胶质细胞是调节大脑突触发育和可塑性的重要细胞类型,但其影响突触的正常功能的机制尚不清楚。在本研究中,我们通过PLX5622造成小胶质细胞耗竭,并观察其对成年野生型小鼠海马CA3-CA1突触的影响。在小胶质细胞耗竭后,与树突棘密度降低相关的自发和诱发谷氨酸能活动的减少,出现未成熟突触特征以及突触的可塑性提高。小胶质细胞耗竭的小鼠在新物体识别任务的获取方面表现出缺陷。海马星形胶质细胞出现增生,但并没有神经炎症反应。在Cx3cr1-/-小鼠中,PLX不能导致海马出现上述改变。这说明CX3CL1/CX3CR1轴在小胶质细胞对突触功能的控制中有重要作用。PLX5622停用后,小胶质细胞的重新增殖,海马突触恢复,小鼠的学习功能也出现恢复。综上所述,小胶质细胞对维持成人大脑的突触的正常功能用重要的作用,去除小胶质细胞会导致谷氨酸能突触组织和活动的可逆变化。

Background: Breast cancer is a type of cancer that affects more women throughout the world, in developing anddeveloped countries. 2-AeH2P is a phospholipid analog of cellular membrane, which makes it different from existing molecules fortheir absorption, stability and display anti-inflammatory, anti-proliferative and pro-apoptotic properties. Methods: MCF-7 humanbreast adenocarcinoma cells were treated with 2-AeH2P. The viability and adhesion cells were evaluated by MTT assay. Cell cyclephases, apoptosis, markers and mitochondrial potential were assessed by flow cytometry. Morphological ultrastructural analyzeswere performed by laser confocal microscopy. Results: MCF-7 Tumor cells acquired round shapes, lost cytoplasmic expansions,formed clusters in suspension and decreased significantly viability. There were changes in the morphology, membrane fragmentationand loss of cytoplasmic projection. The obtained concentrations for IC50% were 37.2;25.8;1.8 mM for periods of 24, 48 and 72 h,respectively. Changes in the distribution of cell population phases of the cell cycle showed an increase in fragmented DNA and anincrease in the G2/M phase. The expression β-gal showed proliferative reduction induced by 2-AeH2P. Laser confocal microscopyshowed changes in the mitochondrial membrane and alteration in distribution. Proliferative index of MCF-7 tumor cells treated with2-AeH2P decreased significantly when compared to fibroblast normal cells. The compound 2-AeH2P is a phospholipid withantiproliferative potential and apoptosis modulator.
