PartⅡThe mechanism elucidation about effects ofα-(2,3)/(2,6)sialic acid on the Cx43gap-junction functions.(1) Westernblotting experiment showed that the decrease of sialic acid didn\'t changethe Cx43 expression and its phospholation level.(2) Westernblotting experiment showed sialidase didn,t change the ZO-1 expression,IP and confocal experiment showed sialidase improved the interaction of Cx43 andZO-1.(3) Westernblotting experiment showed sialidase didn\'t change N-cadherin expression,IP and confocal experiment showed sialidase promoted the complex formation ofCx43 and N-Cadherin.(4)Sialidase could increase the ERK1/2 phospholation level,and enchanedintercellular homotypic adhesion,Immunofluorometric assay showed sialidase couldpromote the N-cadherin cluster on the membrance.

第二部分：α—(2，3)／(2，6)唾液酸对肿瘤细胞CX43间隙连接功能影响的机制研究1、Westernblotting结果表明降低细胞膜表面唾液酸并不改变Cx43的表达及其磷酸化水平：但Cx43连接斑形成增多；2、Westernblotting结果表明唾液酸酶作用后细胞ZO—1表达没有改变，IP及免疫荧光共定位结果表明唾液酸酶作用后促进了Cx43与ZO-1的结合；3、Westernblotting结果表明唾液酸酶作用后细胞N-cadherin表达没有改变，IP及免疫荧光共定位结果表明唾液酸酶作用后促进了Cx43与N-Cadherin复合物的形成；4、唾液酸酶作用后细胞内ERK1／2磷酸化水平明显增加，细胞间同质粘附增加，以及免疫荧光表明唾液酸降低后可促进N-cadherin的膜成簇。

Three Cases with hydronephrosis were located in left kindey, and 3 cases in bilateral kidneys. Of 5 kidneys in 4 cases of ureteropelvic junction obstruction, Anderson-Heny's procedure was performed in 4 kidneys, and nephrectomy was performed in 1 hydronephrotic kidney because the renal function had lost. Cohen's procedure was performed in all 3 individual hydronephrotic kidneys in 2 cases.

病因及治疗：肾盂输尿管连接部梗阻4例5只肾，4只肾做了Anderson-Heny's手术，1只肾无功能行肾切除术；2例3只肾为巨输尿管症，均行Cohen's法输尿管膀胱移植术，其中1例合并膀胱重复畸形，手术中同时行共同壁切除；l例出生后肾积水渐减轻，未特殊处理，正在随访中。

CT scan and MRI study revealed multifocal peculiar hyperostotic bone lesions involving bilateral sternoclavicular junction, lumbar vertebra, and right sacroiliac joint, with mild degree surrounding marrow edema around the lesions.

经过电脑断层与核磁共振检查后发现在两边胸锁关节，腰椎，右侧骶骼关节有著多发性不正常的骨质增生与周围水肿。

It was more differentiated in coculture group than inconditioned group. MSCs and myocytes could form gap junction when cocultured in vitro.Conclusions: MSCs could survive and develop in normal myocardium.

正常MSCs中部分细胞可表达少量Cx43以及titin；条件培养基和混合培养均可促进MSCs的心肌样分化，但后者使分化程度更高；混合培养条件下，MSCs可和心肌细胞之间形成缝隙连接。

In addition to two l-z joints, the medial branches also innervate the multifidus muscle, the interspinous muscle and ligament, and the periosteum of the neural arch.7,28–30 The L5 nerve differs in that it is the dorsal ramus itself that runs along the junction of the sacral ala and superior articular process of the sacrum.29,31 Its medial branch arises opposite the inferolateral corner of the base of the lowest facet joint.

除了l-z关节以外，内侧支还支配多裂肌，棘间肌和韧带以及椎弓处的骨膜。L5神经有所不同，其背侧支本身走行于髂骨翼和髂骨的上关节突。其内侧支在最低关节囊的基底部下外侧角的对面发出。

Microtubules and their textural composite hydrate system, nuclear envelope inside the cell, the places of plasma membrane infolding and cell junction and cell adhesion outside the cell possess lots of nano-scale (100-103 nm) narrow spaces.

在细胞内部的微管及其织构复合水化体系、核膜以及在细胞外部的质膜内褶和细胞连接粘连之处都可以发现许多纳米尺度(100~103 nm)缝隙空间。

The purpose of this study was to determine whether femoral neck fracture after cemented resurfacing hip arthroplasty arises from intraosseous vascularity around the femoral head-neck junction.

本研究的目的是确定骨水泥型髋关节表面置换术后股骨颈骨折是否由于股骨头颈交界处骨内血管引起。

These results suggest that deterioration of the intraosseous vascular network around the head-neck junction after RHA was not severe enough to induce complete avascularity.

这些结果表明，RHA术后股骨头颈交界处的骨内血管网的退变还没有严重到足以引起完全没有血供。译：丁香园，kk8217

At the neural level, Experiment 1 revealed a set of brain regions, including bilateral superior and inferior frontal eye fields, intraparietal sulci, supplementary eye field, regions in the junction between transverse occipital sulci and intraparietal sulci, and anterior insular were activated more when the display was heterogeneous than homogeneous.

在神经活动上，相对于干扰项同质条件，双侧上部和下部额叶眼区、辅助运动眼区、顶间沟、顶枕联合、以及前脑岛区域在干扰项不同质时显著激活；干扰项同质性与目标存在性的交互作用在大脑中表现出两组激活模式不同的脑区。

And Pharaoh spoke to Joseph, saying, Your father and your brothers have come to you.

47：5 法老对约瑟说，你父亲和你弟兄们到你这里来了。

Additionally, the approximate flattening of surface strip using lines linking midpoints on perpendicular lines between geodesic curves and the unconditional extreme value method are discussed.
