凹陷

Results The inpatients characterized with typical facial features, cutaneous basal cell naevus were obviously seen on the skin, palmar or plantar pits were viewed, bilamellar calcification of falx cerebri, bifid, fused or markedly splayed ribs were found, and histologically confirmed odontogenic keratocysts of jaw could be detected in most cases of BCNS.

In order to make the area infected by Hp visible under endoscope, the authors spray bromocresol purple—urea fluid onto gastric antrum mucosa to show color, and then to define whether or where it is infected by Hp because the area infected by Hp will become purple color.

做法是在内镜下经活检孔道将Hp识别液5～10ml喷洒在球部、胃窦幽门区，有糜烂、充血、溃疡、疣状凹陷等病变处，1～2分钟后上述各部如呈紫色即示Hp存在。结果本组阳性者128例，阳性率50.0%。在阳性着色区做粘膜活检，做涂片和石蜡切片用作者研制的乙醇中性红染色，结果100%检出Hp。

In this area, the evolution history of the main faults including Zhen①fault, Zhen②fault and Zhen②′fault is burring. Through the analysis of structural evolution and quantitative research of fault activity, the development history of the three main faults is verified. It also could be supported by structural physical simulation.

南部断阶带是高邮凹陷南部的一个二级构造单元，长期以来真①、真②及真②′等主干断层的发育历史模糊不清，本论文通过对构造演化的分析及对断层活动的定量研究重新厘定了三条主干断层的发育历史，并利用构造物理模拟实验对其进行了验证。

If the posterior teeth or dental prostheses are missing, the cheeks may be sunken, producing a prematurely aged or cachectic appearance.

While the control group had a horizontal curve which had micro changes. To compared with control group, the serum hepcidin contents had a tendency like a cavate parabola which had the lowest on 8th、9th、10th day, the same to the hepatic hepcidin gene expression changes. While control group had the same changes of gene expression .

血清铁调素ELISA检测含量趋势与对照组比较，呈现凹陷的抛物线变化，低值出现在第8、9、10天，整体变化趋势与肝脏基因水平相符合；对照组变化亦与肝脏hepcidin基因水平相符合。
