Description
Technical field
The present invention relates to beyond body nucleic acid detection technique field, more particularly to one kind to be used to detect fentanyl medication related gene
The primer pair and kit of polymorphism.
Background technology
It is elimination pain when performing a surgical operation when anesthesia is or carries out diagnostic test operation, ensures that patient safety, creation are good
Good surgical condition and the various methods taken.Anesthesia is also used for control pain, is performed the operation or when diagnostic test operates, sick
People can feel pain, it is necessary to be allowed to swound with arcotic or other modes.Common Anesthesia medicine includes sedative
Thing:Such as midazolam, Propofol;Central analgesicses:Morphine, fentanyl etc.;Muscle relaxant:Atracuium, along Ah
Bent storehouse amine etc.;Local anesthetic:Lidocaine, Bupivacaine etc..
Fentanyl is artificial synthesized potent narcotic antalgesic, and Analgesic Mechanism is similar to morphine, is opiate receptor
Activator, action intensity are 60~80 times of morphine.Compared with morphine and pethidine, fentanyl effect is rapid, holds time short,
Do not discharge histamine, on cardiovascular function influence it is small, stress reaction during trachea cannula can be suppressed.Gradually taken after fentanyl listing
For the status of morphine main flow analgesic in surgery anesthesia, turn into one of Narcotic analgesic drug being most often selected.Then
Constantly there is new fentanyl class product to emerge, clinical alternative product is also more and more.The product that the country uses at present is main
It is fentanyl, Remifentanil and sufentanil.
Fentanyl is as artificial synthesized opiates potent narcotic antalgesic, and in clinical anesthesia section of China, application is very wide
It is general.But due to the presence of individual difference, Isodose fentanyl effect of drugs and drug metabolism in different patients have aobvious
Difference is write, so as to influence its analgesic effect and adverse reaction.
Fentanyl is mainly metabolized in liver by CYP3A4 enzymes, and CYP3A4 enzymes belong to Cytochrome P450 oxidase system
(CYP), it is most important drug metabolic enzyme.Wherein CYP3A contents in hepatomicrosome P450 are most, account for the half of total amount with
On, the clinical medicine metabolism of participation about 60%.CYP3A4 is one of CYP3A families important member, controls some local anaesthetics, steroid
The metabolism of body class analgesics anti-inflammatory, fentanyl class etc..Research display:Use the fentanyl of same dose, CYP3A4 gene mutations
CYP3A4 enzyme systems can be caused to produce function to sexually revise, reduce fentanyl metabolism, corresponding blood concentration increase, acted on most strong;
Heterozygous mutation is placed in the middle;Wild homozygote blood concentration is minimum, and effect is also most weak.
CYP3A4 is widely present genetic polymorphism phenomenon in crowd, is caused between individual between race to same substrate
One of the reason for metabolic capability difference.The website of P450 allele name at present discloses 55 gene pleiomorphisms.CYP3A4 etc.
Significant race and ethnic origin difference be present in position gene frequency.In Chinese population, gene frequency highest is CYP3A4*
1G, up to 27%.CYP3A4*1G types allelic mutation can cause the activity of CYP3A4 metabolic enzymes to change, and influence correlation
The metabolic capability of medicine, so as to influence its blood concentration.
Researcher is when to Abdominal hysterectomy and myomectomy patient postoperative fentanyl anesthesia analgesia research
It was found that CYP3A4*1G mutation are relevant with fentanyl Postoperative Patient-controlled Intravenous Analgesia effect, postoperative fentanyl consumption can be reduced.Min Yuyuan
Found Deng when being worth to CYP3A4 gene pleiomorphisms to the personalized medicine of Patients with Big Area Burn application Analgesia with Fentanyl:
CYP3A4*1G mutation patient's fentanyl dosages are significantly lower than the patient of control group, thus it is speculated that fentanyl is in CYP3A4*1G gene mutations
Difference caused by individual analgesic effect is due to gene mutation and causes enzyme system expression to change, and drops CYP3A4 enzymatic activitys
It is low.
Department of anesthesia clinician has a strict limitation when using analgesics such as fentanyls, and drug effect deficiency does not reach fiber crops in art
Liquor-saturated standard, surgical effect will be influenceed;Postoperative drug effect deficiency can increase patient suffering;Drug dose can excessively cause respiratory system tight
Adverse reaction again;Chronic pain patient dosage is improper to cause pharmacological dependence.Personalized medicine is rationally adjusted according to Patient genotype
Whole therapeutic regimen, have great advantage improving curative effect with drug safety tool.
This kit is exactly the genotype for distinguishing the CYP3A4*1G sites of different patients, is that doctor's Clinical practice is fragrant
Too Buddhist nun's class Narcotic analgesic drug provides reference, and avoids the generation of the serious adverse reactions such as postoperative pain, respiration inhibition.
Pyrosequencing (Pyrosequencing) is that a kind of DNA sequencing based on polymerization principle (determines nucleosides in DNA
The order of acid) method, belong to DNA sequence analysis technology of new generation, possess while a large amount of samples are carried out with the ability of sequencing analysis,
And there is the advantages of high flux, specificity is high, quick, directly perceived and inexpensive.Its general principle is, by the same of 4 kinds of enzymatics
Enzyme cascade chemiluminescence reaction in reaction system, in each round sequencing reaction, only adds a kind of dNTP, if the dNTP and mould
Plate matches, and polymerase can is incorporated into primer strand and discharges the pyrophosphoric acid group (PPi) of equimolar number, and PPi can
Visible light signal is eventually converted into, and a peak value is converted into by PyrogramTM, is mixed in the height of each peak value and reaction
Nucleotide number it is directly proportional;Then a kind of dNTP under adding, continues the synthesis of DNA;Finally by the feelings for analyzing peak value
Condition, reach the purpose of measure DNA sequence dna.But, CYP3A4 bases also are detected without using pyrosequencing techniques in the prior art
Because of the product of parting.
" goldstandard " that hospital is used for the detection of CYP3A4 Genotypings is PCR- direct sequencings, but direct sequencing is quick
Perception it is not high, tumor tissues of the mutant cell ratio in more than 10-20% can only be detected, for containing<10% mutant cell
Tumor tissues and peripheral blood, Standard PCR-direct sequencing are almost helpless.Compared to direct sequencing, pyrosequencing
Sensitivity is higher, cost is lower.
At present, in the document of existing disclosed report, only apllied China when 2015 of this research team is special
Sharp CN201510672628.0 is used to enter in " goldstandard " (the PCR- direct sequencings) of the detection of CYP3A4 Genotypings to hospital
Innovation of having gone improves;But the technical scheme involved by patent CN201510672628.0, after product puts into clinical market,
Especially during hospital's large-area applications, it is found that designed primer and kit specificity are not also especially high, detections
As a result accuracy can also fluctuate once in a while, thus it is speculated that be probably the environment of design of primers and hospital's actual molecules diagnostic test room
Adaptability problem be present;Therefore, design of primers optimization and corresponding PCR system stability still have larger room for improvement;We
In many ways after investigating each hospital clinical molecular diagnostic laboratories environment and the problematic examining report result of statistical analysis, comprehensively to this
Item purpose primer has carried out re-optimization design, and optimizes PCR reaction systems, significantly improves reagent kit product.
The content of the invention
In order to solve testing result be present during above method detection fentanyl medication correlation CYP3A4 gene pleiomorphisms
Accuracy is not high, detection cycle is long, cumbersome and be difficult to the technical problem for meeting clinical examination requirement, and the present invention provides a kind of
Testing result is accurate, specificity is high, detection cycle is short, cost is low, meets quantitatively and effectively the detection sweet smell of clinical examination requirement too
