Results: Expression of PAI1,TIMP1 and FN in kidney of diabetic rats began to increase in the second week of diabetes; PAI1 and TIMP1mainly expressed in intracytoplasm of renal tubular epithelial cells, while FN mainly expressed in renal tubule matrix and glomerului; Their expression showed a tendency of increasing along with the progression of diabetes.

本实验以糖尿病大鼠为动物模型，动态观察糖尿病2周、4周、8周、16周大鼠肾脏PAI1、TIMP1及FN表达的变化，从ECM代谢的角度探讨PAI1和TIMP1在糖尿病肾病肾纤维化发病机制中的作用。

Objective To explore the effect of high serum concentration of bile acids on energy metabolism of liver.Methods Bile acids were continously infused into the Wistar rats to simulate the serum concentration change of patients with obsturctive jaundice.Serum bile acids concentration,arterial blood ketone body ratio and energy charge of liver were determined.Results Aterial blood ketone body ratio and energy charge of liver decreased with the increase of serum bile acids concentration.Conclusion High serum concentration of bile acids plays an important role in hepatic fumction injury caused by biliary obstruction.

目的 探讨高胆汁酸血症单一因素对肝脏能量代谢的影响方法经Wistar大鼠颈内静脉持续给予外源性胆汁酸，升高其外周血清中胆汁酸浓度，模拟阻塞性黄疸患者外周血清中胆汁酸的变化规律，观察腹腔动脉血酮体比值及肝组织能荷变化，时间一周结果随外周血清中胆汁酸浓度的升高，腹腔动脉血酮体比值、肝组织能荷均呈进行性下降结论高胆汁酸血症时肝脏能量代谢受损，表明在阻塞性黄疸患者肝功能损害中高胆汁酸血症起了重要作用

Prussian blue staining revealed more than 98% of BM-MNCs were labeled by Feridex and BM-MNCs appeared to be unaffected by magnetically labeling. Three dogs injected Feridex- BM-MNCs were visualized at one week by MRI, but none of unlabeled BM-MNCs were seen. All lesions that were detected within one week could not be visualized over four week. The dot injected Feridex-cells which fixated by 4 % methanal also was seen at one week by MRI, but the signal disappeared at two week.

普鲁士蓝染色显示体外Feridex标记BM-MNCs成功率达98%以上，而且细胞活性不受影响；其中3只实验犬标记细胞移植区1周内可用1.5T磁共振仪3DSSFP序列在体扫描到T2低信号影像，4周时该低信号消失；同样条件下经甲醛固定的标记细胞在1周时也可检测到T2低信号，但2周时该低信号消失；未标记细胞移植区没有检测到低信号。

Rat AAA model was made by perfusion PPE elastase through the abdominal aorta, and the specimen was obtained on postoperativeday 3, 7, 14, 28, respectively. Specific elastic fiber staining was used to observe the disruption of elastic fiber in aortic wall. Immunohistochemistry staining of CD68 was applied to observe the microphage infiltration. The in tisu hybridization and western blot of MCP-1 and MMP-2 were used to study the expression of mRNA and protein. Thus we can analyze the facilitated function of MCP-1 gene to the microphage adherence and infiltration on the earlier AAA.

采用经腹主动脉腔内导管灌注的方法制成大鼠AAA模型，分别于术后3天、1周、2周、3周、4周获取各组大鼠腹主动脉标本，行弹力纤维特殊染色观察动脉壁弹力纤维的破坏情况；行CD68免疫组织化学染色观察动脉壁中巨噬细胞的浸润；行MCP-1及MMP-2的原位分子杂交、Western蛋白质印迹观察二者的mRNA表达和蛋白表达；分析MCP-1基因促进巨噬细胞的黏附、浸润在早期AAA发病中的作用。

Every other week, our school ends in the mid of Friday(other times it ends on Saturday midnoon).

而现在也分成了大周和小周，小周是周六中午回家。大周则是星期五中午回家。

Then, the volume and morphology of grafts were observed and proliferating cell nuclear antigen expression of mammary epithelial cells in grafts was detected by immunohistochemistry. Experiment two: From 2 to 6 weeks after implanting, B-E〓 or NH1996 with respective dosage of 20ug and 100ug were injected muscularly into four groups of host mice once two days, and the control group was designed without treated with hormone.

结果：1。植入2周和6周乳腺组织形态结构保持完整，植入2周乳腺组织块体积、腺体数目和增殖程度均较植入时明显降低，并以此水平维持至植入6周。2.B-〓对植入的乳腺组织形态学无明显影响，但可引起乳腺上皮细胞PCNA、Bcl-2蛋白表达的升高；B-〓可上调PR，下调ER，说明植入裸鼠的正常乳腺对B-〓有反应，证实模型建立成功。

MethodsThe thickness of nuchal skin of 900 normal fetal was measured by abdominal ultrasound with 7.5 MHz probe.

结果孕 2 7周前正常胎儿颈项皮肤只能显示全层；≥ 2 7周可显示表皮真皮层和皮下组织层。厚度范围：( 1.18± 0 。0 5 )mm ( 10周)～( 6.0 1± 0 。46)mm ( 4 0周)。

Whether Zhou s triangulation would derive MWT of a planar point set, Zhou Peide had drawn a new conclusion before the comments "Zhou s Triangulation is not the minimum weight triangulation " were given.

周培德三角剖分是否能得到最小权三角剖分，周培德在《周培德三角部分不是最小权三角剖分》一文撰写之前已有新的结论，本文还指出《周培德三角剖分不是最小权三角部分》一文所举反例不成

Results］The gross morphology of the tendons showed the experimental group had lesser adhesion and better reactiveness than that in the control group.The fibrin had degraded at 3 weeks.

分别于术后1周，3周，6周及12周对移植部位进行大体标本观察，细胞示踪、组织学检查、免疫组织化学检查、形态测定分析及生物力学测定。

We assessed the patients at week 0、week 2、week 4 and week 8, using the Hamilton Depression Scale and the Self-Rating Depression Scale.

The split between the two groups can hardly be papered over.

这两个团体间的分歧难以掩饰。

This approach not only encourages a greater number of responses, but minimizes the likelihood of stale groupthink.

这种做法不仅鼓励了更多的反应，而且减少跟风的可能性。
