Description
Technical field
The present invention relates to biological cell, tissue staining technical field and cytology is qualitative and DNA quantitative detecting analysis methods,
Specifically cut into slices after specific stain, while carrying out qualitative and quantitative determination.
Background technology
, used as modern pathology component, because of its draw materials convenience, relative noninvasive, detection is quick and economical real for cell pathology
With increasingly receiving publicity.Traditional cell detection method refers to that tester passes through under the microscope observation of cell morphological feature
Change, so as to judge whether cell occurs pathology.In order to the effective observation of cell, generally need to enter cell before testing
Row dyeing, conventional colouring method has haematoxylin eosin staining procedures, Papanicolaou's vaginal smear technique, shore decoration method etc..These methods it is many according to
Acidity of Aikalinity according to different organelles is different, so as to reference to the dyestuff of different colours, to distinguish cell membrane, cell under the microscope
Some changes of slurry and nucleus and cell other structures.This morphological analysis are only observer, and to present some thin
Born of the same parents' feature(Such as there is situation in nucleus size, karyoplasmic ratio or nuclear particulate).Due to individual otherness, cause cell
Can complex shape be changeable, accurately judge and understand metamorphosis whether real pathology actually, depends primarily on cell and studies medicine
Raw experience and qualification, therefore, the subjective repeatability of testing result is bad.Due to the restriction of naked eyes identification, also very
Hardly possible distinguishes the property of Junctional rhythm, or cannot find the atypical pathology of some morphological changes, can unavoidably cause
The case that certain amount is failed to pinpoint a disease in diagnosis.
Chromosome is a complete Encyclopedia of Life, and each species has the chromosome of a set of uniqueness(That is chromosome
Group), for the presence of species, chromosome has decisive role.Meanwhile, fine mitosis mechanism also ensure that dyeing
During passage, quantity and structure remain stable to body.But carcinogen, rare inherited disorder and accidental
Mitosis mistake is destroyed may this stable state.Beginning of the century in 19 end of the century 20, David von Hansemann and
Theodor Boveri Von Hansemann have found that all cancer cells all contain abnormal chromosome.With entering for detection technique
Step, more and more as shown by data:Cancer cell and just all can run counter to " genome is stable " in the namely sick cell of canceration
This law of nature, by producing the cell of quantity abnormal chromosome tumour is caused.The abnormal quantity of chromosome makes total with thousand
The gene of meter and they encode protein be in imbalance state so that cell produce malignant phenotype, also for cell development into
Condition is created for more serious chromosome abnormality cell.Cancer cell numerical abnormalities of chromosomes degree is higher, chromosomal variation speed
Degree is faster, therefore the pathology situation of cell can be judged by the change detection to chromosome number in nucleus or DNA content,
This belongs to quantitative determination.DNA specific stains are first passed through, cell DNA is marked, because dyeing is chemical reaction, can be
Label sets up linear relationship and DNA content between, by detect label number, judge DNA content size.It is this
Method can be good in the change of pathology early detection inhereditary material, sensitiveness;Detection is carried out by equipment, with the experience of operating personnel or
Qualification is unrelated, it is to avoid the error that subjective factor is caused, reproducibility of results is good.But the colouring method used in this detection is made
Nucleus is can only see when detection, in the case of shortage is cytoplasmic, it is impossible to judge sick cell type.Additionally, checking
During nucleus, as without cytoplasm, but the core by dyeing is difficult to distinguish impurity in sample or real thin
Karyon, if impurity is mistaken for into diagnosis cell, will also result in mistaken diagnosis.The graphical analysis of DNA measurements is overlapped to multiple nucleus
The segmentation of i.e. agglomerating core is difficult point, typically directly skips this kind of cell, nonrecognition, and this can cause to fail to pinpoint a disease in diagnosis.
Therefore, the method dyeing time of cytomorphology qualitative analysis is short, and flow process is simple, but unstable, will to technician
Ask high, diagnosis is based only on the morphological feature of cell, the experience and skill of dependent cells scholar, misdiagnosis rate is very high;DNA is quantitative
, based on DNA special colouring method, dyeing time is long, and dyeing condition has high demands, and reagent is unstable for analysis method.DNA measurement according to
The nuclear features of Lai Yu, to individual cells nuclear energy measurement is split well, for multiple nucleus overlaps are dividing for agglomerating core
The difficult point that measurement is DNA quantitative analyses is cut, this kind of cell, nonrecognition is typically directly skipped, and can not provide any with regard to cell
Information in terms of morphology.
The content of the invention
The technical problem to be solved in the present invention is:Overcome the deficiencies in the prior art, there is provided a kind of cell pathology section is quick
Dyeing detection method, makes dyeing time short, and flow process is simple, and section after dyeing can simultaneously carry out cytomorphology analysis and nucleus
DNA quantitative determinations, improve the degree of accuracy of sick cell detection.
The technical solution adopted for the present invention to solve the technical problems is:A kind of cell pathology section rapid dyeing detection side
Method, comprises the following steps:
1st step:Dyeing process is carried out to section, makes nucleus and cytoplasm catch color, and both contaminate color contrast

Step(4):Repeat the above steps(1)-(3), until sweep parameter index IOD of same standard section(Integral light is close
Degree), diploid cell standard variance CV and tetraploid IOD and dliploid IOD linear relationship, DNA testing equipments with
In the range of allowable error, correction is completed parameter its difference that the scanning of standard quality control system is obtained.
Digital color camera collection cellular morphology figure is clapped in the case where high resolution microscope is set to 20 times in 2nd step
Take the photograph, testing staff can point out without the need for diagosis under mirror according to DNA content, reading section picture can make diagnosis, save diagosis people
Member's time, improve diagnosis efficiency.
Concrete steps in 3rd step include:
I:Choose the normal cell in same section and do internal reference cell, and contained all nucleus according to DNA by inspection software
The descending order arrangement of amount;
II:During DNA content quantitative analysis, corresponding nuclear full cellular morphology can be observed, determine whether real cell
Core and karyoplasmic ratio, metamorphosis, and cell type is judged;
III:During cytomorphology interpretation, inspection software presses the corresponding cellular morphology figure of the descending arrangement of nuclear DNA content
Piece, points out according to DNA content, and reading section picture can make diagnosis;
Ⅳ:Multiple nucleus overlaps are agglomerating core image segmentation and calculate the DNA content of these agglomerating cores by inspection software, then
By cytology qualitative analysis;
Ⅴ:According to II, III, IV step comprehensive analysis, judge to be detected cell as normal or improper.
The present invention is presented at short notice clear face as a result of special colouring method, nucleus and cell mass-energy
