for the diagnostic criteria of pathology doctor reference
1., owing to comprising gland cell, columnar cell and monocyte at cervical canal inner cell all containing highly active acid phosphatase expression of enzymes, therefore first when assessing NM-PAP coloration result need be distinguished cytomorphology and be ignored.
2. occur that red granules shape sediment is considered as the positive in pair ripe epithelial cell, middle layer cells and nearly basal layer cell endochylema, simultaneously according to the increase of its core and the abnormal TBS according to calendar year 2001 revision in addition classification by stages:
(1) Atypical squalors cell (ASC):
(I) Atypical squalors cell (ASC-US) of interrogatory,
(II) not except the Atypical squalors cell (ASC-H) of epithelium inner height pathology;
(2) low Squamous cell lesions (LSIL);
(3) high-grade squamous epithelial lesion (HSIL);
(4) squamous cell carcinoma (SCC).
3. suggestion is slight but have the NM-PAP positive expression case that positive cell number is less than 3 simultaneously to give the diagnostic result of " the early stage slight abnormality of epithelial cell " to cellular morphology change.
Result
Fig. 1, Fig. 2 are the Normal squamous epithelium of traditional pap staining display.Different colors is presented because of the acidophilia of squamous cell and basophilous difference.
Fig. 3, Fig. 4 are the Normal squamous epithelium of independent modified pap staining display.Visible unified blue background, eucaryotic cell structure and clear layer.
Fig. 5, Fig. 6 are the Atypical squalors cell (ASC-US) of the interrogatory of new method dyeing display.Therefrom have red granules shape sediment in high-visible abnormal cell endochylema, karyon compares with normal cell obvious increase.
Fig. 7 is new method dyeing display squamous cell abnormal in early stage, and whole smear only has this individual cells abnormal, and visible endochylema red granules precipitation and karyon increase.
Fig. 8 is that new method dyeing display dermoid cancer venereal disease becomes (SSC), and gather in endochylema red granules sediment, and karyon obviously increases.
The colour developing of the enzyme of Fig. 9 Hela cell after traditional immobile liquid (95% alcohol) is fixing, its colour developing is not good.
The enzyme colour developing of Figure 10 Hela cell after special immobile liquid is fixed, chemical staining presents red granules.
Above result shows and through clinical verification, acid phosphatase stain disclosed herein combines the pap staining of improvement, this new colouring method is compared with traditional Papanicolaou's vaginal smear technique, and the diagnosis susceptibility of cervical squamous cells cancer or precancerous lesion improves, and can be increased to about 30%.Or new colouring method disclosed herein can make the false negative rate of the diagnosis of cervical squamous cells cancer or precancerous lesion be reduced to nearly 0%.New immobile liquid disclosed herein can guarantee the above-mentioned effect of described new colouring method further, can shorten the set time, maybe can improve Color, such as, improve the Color of acid phosphatase.In addition, described new method can also find the ANOMALOUS VARIATIONS that cervical squamous cells is very early stage, and this simple change according to cytomorphology in the diagnosis of traditional Papanicolau staining process almost cannot realize.
