Linear correlation was analyzed by diluting HBsAg-positive samples with normal healthy sera in series.

正常人血清标本中分别加入一定比例的上述样品至S／Co比值在阈值并重复检测40次作重复性实验；气泡检出试验是在样品中加入50μL气体并重复检测20次；正常人血清连续系列稀释HBsAg强阳性标本并检测线性范围试验。

METHODS: A total of 129 gastric mucosa biopsies and its corresponding serum specimens were collected from patients with superficial gastritis (n=30), gastric ulcer or erosion (n=35), atrophic gastritis (29), and gastric cancer (n=35). The expression of PGC in the gastric mucosa was detected by immunohistochemistry, and the concentration of serum pepsinogen A and pepsinogen C were determined by enzyme linked immunosorbent assay.

129例胃黏膜活检组织及其血清标本（浅表性胃炎30例，胃黏膜糜烂溃疡35例，萎缩性胃炎29例，胃癌35例），采用免疫组织化学染色检测胃黏膜标本中PGC的表达情况；采用酶联免疫吸附实验检测血清PGA和PGC含量。

It can also provide good specimen in cardiovascular learing. Perchloroethylene ethyl acetate plastics filler perfusion is a good technique in making specimen.

该方法能够制作出完整的心脏动脉铸型和局部房室结动脉铸型，标本利于观察分析血管走行及分布，并为解剖实验学习心血管课程提供良好的铸型标本。

Urogenital swabs were inoculated on the conventional solid media, new solid media and urea liquid media as such.⑤Synovial fluid, synovial-membrane biopsy samples, blood, urogenital swabs and pharyngal swabs from RA were examed the presence of mycoplasmas using culture and Polymerase Chain Reaction assay.

46例泌尿生殖道标本直接划在固体培养基表面后洗脱在Uu液体培养基和Mh液体培养基中；另20例标本直接划在无青霉素的固体培养基后洗脱在Uu液体培养基中。

So it is a major tool to accumulate and organize the pathologic information by effectively using digital photomicrography to collect image data of the specimen.

利用数码显微摄影进行病理玻片标本资料的采集，是病理资料积累和管理的重要手段之一，完善的病理玻片标本资料对医疗、教学和科研都起着非常重要的作用。

In Shaomin Shen's studio in Daqing, I think of life and death, yin and yang, when faced with over 2000 mouse's' bones repaired by overwork of more than ten assistants, five sets humankind bones endowed with the feathers of "Unusual Scene" specimen, a complete virus lab, virus lab process with work tables, vessel used for experiment, experimenters, slices, and specimen, and stimulant plague spot.
