Neurotransmitter inactivation is important for the origin of nerve system in animal early evolution: a suggestion from genomic comparison

Metazoans possess complicated multicellular structure among the multicellularities of eukaryotes. One evolutionary pressure that permits such complexity relates to the directed and precise informational transmission performed by numerous synapses in neuron system. Neurotransmitter inactivations play essential roles in the termination of synaptic transmission and are thus crucial for precise synaptic transmission. Here, we performed a genomic comparison among 11 eukaryotic organisms including five bilaterian species and six pan-unicellular eukaryotes to search for genes related to metazoan multicellular function. The result showed that the majority of genes related to neurotransmitter inactivation in the synaptic cleft endured high and stable selective pressure and were specifically present in bilaterians, whereas genes related to transmitter release and postsynaptic transmitter receptors did not show these properties. From these data we conclude that neurotransmitter inaction may play a critical role in the origin of the nerve system encountered in the early evolution of metazoan. In addition, we suggest that neurotransmitter inactivation probably participates in the formation or refinement of the synapse, following the concept of “ontogeny recapitulates phylogeny.” Further experimental evidence is needed to support the suggestion and to explain the importance of neurotransmitter inactivation to metazoan multicellular function.     

病机的主体地位及其构建过程是中医学的核心内涵

分析了当前的中医药发展形势,指出真正制约中医药事业发展的瓶颈并非物质条件,而是某些中医从业人员学术指导思想的异化;由此认识到针对中医学的基本属性和内涵开展讨论,以正本清源是十分必要的。中医学内涵的核心就是病机的主体地位及其构建过程。分析了病机的核心价值及其学术基础,这一基础的实质是基于发生学的东方文化的系统属性,它与当代的系统科学——复杂适应系统理论(Complex Adaptive Systems Theory)具有内在的一致性。     

2002～2012年阴道分泌物真菌检出变化趋势

目的 了解阴道分泌物真菌检出变化趋势及女性生殖道真菌感染现状.方法 对2002～2012年我院门诊和住院患者阴道分泌物涂片妇科多项检查记录资料回顾性统计分析,对阴道分泌物真菌年度检出率对比分析.结果 2002～2012年11年间阴道分泌物真菌检出率依次为12.76％、13.26％、17.48％、18.89％、15.32％、14.93％、14.10％、13.55％、9.87％、8.65％、9.53％,平均阳性率为13.68％;18～44岁年龄组真菌检出率14.98％,44～70岁年龄组真菌检出率9.49％.结论 2002～2005年4年间阴道分泌物真菌检出率总体呈上升趋势,2005 ～2012年7年间阴道分泌物真菌检出阳性率总体呈下降趋势;44岁以下年龄组妇女阴道真菌感染率高于45岁以上年龄组;合理使用抗菌药物,良好的生活、卫生习惯对降低阴道真菌感染有积极作用.     

戊乙奎醚与依托咪酯用于无痛胃镜诊疗的对照研究

目的观察戊乙奎醚与依托咪酯在无痛胃镜诊疗中应用的利弊。方法选择美国麻醉师协会(ASA)Ⅰ～Ⅱ级,于我院行无痛胃镜检查或治疗的患者100例,随机分为2组,A组(常规组)48例,诱导用药:阿扎司琼0.2mg/kg、芬太尼1μg/kg、丙泊酚2mg/kg,序贯静脉注射;维持用药:间断给予丙泊酚;B组(依托咪酯组)52例,诱导用药:戊乙奎醚0.01mg/kg、阿扎司琼0.2mg/kg、芬太尼1μg/kg、依托咪酯0.15mg/kg、丙泊酚1mg/kg,序贯静脉注射;维持用药:间断给予丙泊酚、依托咪酯。比较2组的诱导时间、血流动力学指标(意识消失时、胃镜插入后即刻、胃镜拔出后即刻的血压、心率)、呼吸抑制的发生率、苏醒时间及术后并发症的发生率。结果 2组诱导时间差异无统计学意义,A组呼吸抑制发生率高于B组(P<0.05),苏醒时间明显短于B组(P<0.05),B组术后并发症的发生率明显高于A组(P<0.05),且复视多见于青年人,谵妄多见于老年人。A组麻醉后各时点的血压、心率明显低于麻醉前及同时点B组水平(P<0.05),A组意识消失时的血压低于胃镜拔除后即刻(P<0.05);B组麻醉后各时点的血压、心率稍降低,但与麻醉前相比差异无统计学意义(P>0.05)。结论在无痛胃镜诊疗中推荐应用依托咪酯,尽量避免应用戊乙奎醚。

MicroRNA-374a activates Wnt/β-catenin signaling to promote breast cancer metastasis

Tumor metastasis involves a series of biological steps during which the tumor cells acquire the ability to invade surrounding tissues and survive outside the original tumor site. During the early stages, the cancer cells undergo an epithelial-mesenchymal transition (EMT). Wnt/β-catenin signaling is known to drive EMT and metastasis. Here we report that Wnt/β-catenin signaling is hyperactivated in metastatic breast cancer cells that express microRNA 374a (miR-374a). In breast cancer cell lines, ectopic overexpression of miR-374a promoted EMT and metastasis both in vitro and in vivo. Furthermore, miR-374a directly targeted and suppressed multiple negative regulators of the Wnt/β-catenin signaling cascade, including WIF1, PTEN, and WNT5A. Notably, miR-374a was markedly upregulated in primary tumor samples from patients with distant metastases and was associated with poor metastasis-free survival. These results demonstrate that miR-374a maintains constitutively activated Wnt/β-catenin signaling and may represent a therapeutic target for early metastatic breast cancer.     

我国南,北方神经管缺陷病因学初探

对１９８６～１９８８年间监测的４１３４例神经管缺陷进行了病例对照（１：１）研究。对照为在同一医院紧接畸形儿出生的一例非畸形活产儿。采用非条件Ｌｏｇｉｓｔｉｃ回归方法控制混杂因素后，发现南北方神经管缺陷的发生均与母亲孕早期接触射线、噪声、化学物、农药有关。孕早期感冒并发热或不发热（南方、北方组）、服用磺胺（北方组）、避孕药（北方组）、中草药（南方、北方组）等亦可增加神经管缺陷发生的危险性。
