Diagnostic criteria for pathology doctor reference
1. owing to comprise that at the cervical canal inner cell gland cell, columnar cell and monocyte all contain highly active acid phosphatase expression of enzymes, therefore when assessment NM-PAP coloration result, at first need on cytomorphology, to be distinguished and ignore.
2. be considered as the positive to red granules shape sediment occurring in ripe epithelial cell, middle layer cells and the nearly basal layer cell endochylema, simultaneously according to the increase of its nuclear with unusually according to by stages in addition classification of the TBS of calendar year 2001 revision:
(1) squamous cell (ASC) that is not true to type:
(I) squamous cell that is not true to type (ASC-US) of interrogatory,
(II) not except the squamous cell that is not true to type (ASC-H) of epithelium inner height pathology;
(2) low scaly epithelium pathology (LSIL);
(3) height scaly epithelium pathology (HSIL);
(4) squamous cell carcinoma (SCC).
3. suggestion changes the diagnostic result that case slight but that have NM-PAP positive expression while positive cell number to be less than 3 gives " the early stage slight abnormality of epithelial cell " to cellular morphology.
The result
Fig. 1, Fig. 2 are the normal squamous cell that traditional pap staining shows.Acidophilia and the basophilous different different colors that present because of squamous cell.
Fig. 3, Fig. 4 are the normal squamous cell that independent modified pap staining shows.As seen unified blue background, eucaryotic cell structure and clear layer.
Fig. 5, Fig. 6 are the squamous cell that is not true to type (ASC-US) of the interrogatory of new method dyeing demonstration.Therefrom in the high-visible abnormal cell endochylema red granules shape sediment is arranged, karyon and normal cell relatively have obvious increase.
Fig. 7 is that new method dyeing shows the squamous cell abnormal in early stage, and whole smear only has this individual cells unusual, and visible endochylema red granules precipitation and karyon increase.
Fig. 8 is that new method dyeing shows that the dermoid cancer venereal disease becomes (SSC), the red granules sediment that gathers in the endochylema, 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 fixing, chemical staining presents red granules.
Above result shows and through clinical verification, acid phosphatase stain disclosed herein is in conjunction with the pap staining of improvement, this new colouring method is compared with traditional Papanicolaous vaginal smear technique, and the diagnosis susceptibility of cervical squamous cells cancer or precancerous lesion improves, and can be increased to about 30%.Perhaps, 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 further be guaranteed the above-mentioned effect of described new colouring method, can shorten the set time, maybe can improve Color, for example improves the Color of acid phosphatase.In addition, described new method can also be found the ANOMALOUS VARIATIONS that cervical squamous cells is very early stage, and this simple variation according to cytomorphology in the diagnosis of traditional Papanicolau staining process almost can't realize.
