Methods Thirty-nine patients with oligospermia were included in the trail. Cell blocks of seminal fluid were made and were observed under light microscope. Expression of PCNA and P16, incidence of apoptosis in spermatogenic cells were detected by immunohistochemistry and in situ 3'DNA end labeling technique.

39例原因不明少精子症患者留取精液，制备细胞块切片，采用免疫组化技术观察生精细胞增殖细胞核抗原及P16的表达；采用原位3'羟基末端标记法观察生精细胞凋亡。15例正常精液作为对照。

The present research was aimed at establishing genetically engineering cell lines that overexpress the C-terminal fragment of human APPgene.

Polyaxial locking plates thatallow screw angulation and end-point locking have become available; however, there are no clinical data documentingtheir strength and efficacy, to our knowledge.

多轴锁定钢板允许螺钉成角和末端锁定，但是据我们所知尚无临床数据证实它们的强度和作用。

上颌骨较圣贤孔子鸟向前突出，指骨爪没有圣贤孔子鸟那样伸长、强壮，胸骨比较拉长，前喙中央有一凹刻构造成&V&字形，同时胸骨两侧有一对短的后侧突，跗蹠骨较圣贤孔子鸟短，以及尾综合、骨末端膨大。

Amino acid mutant site A43V locates in N-terminal headpiece of represser protein which binds specifically to DNAand amino acids mutant sites S93L, S102N, G315S, Q180R, M2491, I283T all locate in the core region of represser protein which binds to IPTG.

氨基酸突变位点A43V位于阻遏蛋白氨基末端，是阻遏蛋白和操纵基因的结合区；S93L、S102N、G315S、Q180R、M249I、I283T均位于阻遏蛋白核心区，即阻遏蛋白和IPTG结合区。

Methods This study contained a total of 16 culture groups, including one group as control and 5 groups treated by 5 drugs (calcium L-threonate, sodium L-threonate, alendronate, 17β-estradiol and calcium gluconate) each at the final concentrations of 10^(-9)mol/L, 10^(-7)mol/L, 10^(-5)mo1/L respectively. After 7 days, eight bone slices of every group were stained with toluidine blue and the areas of resorptive pits were analyzed under light microscope; the concentrations of C-telopeptide of type Ⅰ collagen CT(subscript x or Crosslaps in culture supernatants were measured by ELISA.

制备骨磨片，培养OC，并分别加入高中低浓度10^(-5、10^(-7)、10^(-9)mol/L的L-苏糖酸钙、L-苏糖酸钠、阿仑麟酸钠、17β-雌二醇、葡萄糖酸钙，实验设以上各浓度组及对照组（共16组，每组n=8），甲苯胺蓝染色一光镜观察分析骨片上骨吸收陷窝面积，ELISA测定上清液Ⅰ型胶原C-末端肽（CTx或Crosslaps）浓度。

The roentgenological manifestations were mucosal fold changes, filling defects, luminal stenosis, changes of cecum and terminal ileum involvement etc.
