针对长时间远距离的深空探测任务,需要建立人工闭合的生物再生生命保障系统,而植物单元是生物再生生命保障系统中最为重要的系统单元.微生物作为系统内数量最多的乘员,它的群落结构的变化值得深入研究.选取"月宫一号"105天有人密闭综合实验过程中典型作物小麦作为研究对象,采用平板计数法和聚合酶链式反应-变性梯度凝胶电泳(PCR-DGGE)对小麦叶面和根际的细菌进行研究.小麦叶面的细菌数量在实验前期、中期和后
背景 唇腭裂是最常见的颌面部先天畸形之一。由于唇腭裂修复手术以及自身发育原因，随着生长发育唇腭裂病人常常表现出上颌发育不足、反颔畸形，严重地影响唇腭裂病人颌面部功能、形态以及心理状态。唇腭裂病人面中部通常为上颌骨、颧骨和牙槽嵴区域三维方向发育不足，下颌骨通常为发育正常或轻度前凸。据文献报道，约14-75％的此类病人需要正颌外科手术治疗。但传统的正颌外科手术受到病人年龄、颌骨畸形的严重程度以及病人自

Objective: The nucleus of the solitary tract (NTS) is a primary center for both visceral afferents and somatic afferents.Previous experiments demonstrated that NTS is associated with connection of the
Dense cranial electroacupuncture stimulation (DCEAS) is a novel brain stimulation mode in which electrical stimulation is delivered through dense forehead acupoints innervated by the trigeminal sensor
Objective: The purpose of this study was to explore the effects of needling different acupoints and rules of temperature transmission along meridians by observing the skin temperature changes on acupo
Objective: The objective of this study was to explore the possibility of using functional magnetic resonance imaging (fMRI)technique in the research of central mechanism of acupuncture effects in the
Objective: Modem medical studies have shown that primary dysmenorrhea may be associated with uterine position, and acupuncture has a special regulation on the uterus.
Objective: To evaluate and analyze the effects of children scalp acupuncture combined with Bobath training on neurodevelopment of the infants with perinatal hypoxic-ischemic brain damage (HIBD).
