Description

A kind of primer pair for detecting hoptoglobin parting and its application
Technical field
The present invention relates to biomedicine field, more particularly, to a kind of primer pair for detecting hoptoglobin parting and It is applied.
Background technology
People with diabetes increasingly increases at present, also gradually tends to rejuvenation, and these patients have very high concurrent painstaking effort The risk of pipe disease, the diabetic that rough Statistics there are about 75% die from angiocardiopathy.In order to mitigate patient's hyperglycemia Symptom, reduce the generation of capilary and macrovascular complications, enabled the patient to normally live, using suitable medicine Prevention of cardiovascular complication is particularly important.Because diabetic's complicated with cardiovascular disease and vivo oxidation stress have certain phase Guan Xing, therefore American Society of Cardiology and WHO (WHO) recommend the antioxidants such as vitamin E to prevent Diabetic's cardiovascular complication.
Clinical discovery, different diabetics are very big for difference on effect caused by vitamin E supplement.Some trouble Person's replenishing vitamins E can substantially reduce risk of cardiovascular diseases;And some patients after replenishing vitamins E on the contrary, on the contrary can Increase the risk of complicated with cardiovascular disease, death incident is resulted even in when serious.
A large amount of scientific researches find, the concurrent close phase of cardiopathic risk of the genotype of hoptoglobin and diabetic Close.Wherein, it is higher that diabetic's suffering from heart disease complication, the risk of apoplexy even death of Hp2-2 genotype are carried, about To carry 5 times of the diabetic of Hp1-1 genotype;And the heart disease for carrying the diabetic of Hp2-1 genotype is concurrent Risk falls between.And in terms of the therapeutic effect after replenishing vitamins E, for carrying hoptoglobin Hp2-2 genes The diabetic of type, after 18 months vitamin E treatments, the probability ratio of heart disease and stroke breaking-out does not take vitamin E Similar patient few 50%, and do not occur side effect.And to the diabetic of Hp2-1 or Hp1-1 genotype, replenishing vitamins E can then improve the risk of its complicated with cardiovascular disease on the contrary.
Hoptoglobin (Haptoglobin, Hp) is also known as haptoglobin, is one kind sugar in Serum A 2- globulin fractions Protide, it is a kind of anti-oxidant albumen of the stable erythrocyte hemoglobin of energy, vascular wall can be protected to avoid being inflamed.The mankind The gene of hoptoglobin is located at Chromosome 16q 22.1, and common Hp has three kinds of genotype in crowd, is Hp1-1, Hp2- respectively 1 and Hp2-2, a pair of alleles Hp1 and Hp2 being controlled by Hp seats, in codominant inheritance.Different regions and ethnic group Hp1 and HP2 gene frequencies are different, and the statistics of west crowd is shown, the probability of Hp1-1 genotype is 16%, Hp2-2 The probability of genotype is 36%, and the probability of Hp2-1 genotype is then 48%.Asian is in the majority with Hp2-2, is secondly Hp2- 1, and Hp1-1 is minimum, Han nationality of China ethnic group Hp1 genotype frequencies are relatively low, more based on Hp2.
In summary, the diabetic's complicated with cardiovascular disease for carrying hoptoglobin Hp2-2 genotype is even dead It is higher to die risk, its risk can be reduced by taking vitamin E;Although carry the diabetic of Hp2-1 or Hp1-1 genotype simultaneously It is relatively low to send out risk of cardiovascular diseases, but its coincidence risk can improve on the contrary after taking vitamin E.Therefore, in order to preferably analyze Judge the coincidence risk of diabetic's angiocardiopathy, reasonably carry out early intervention, and clinically give more reliable standard True medication guide, the Genotyping that globin is combined for people with diabetes are very necessary.
The method of detection hoptoglobin parting is mostly electrophoresis at present, first makes testing sample and hemoglobin shape before electrophoresis Into Hp-Hb (hoptoglobin-hemoglobin) compound.The peroxidase activity of hemoglobin can be utilized after electrophoresis is complete Benzidine is set to be oxidized to benzidine blue in the presence of hydrogen peroxide, dyeing plain edition can use polyacrylamide gel eletrophoresis Parting.Hp hypotypes then need the Hp in first purification of samples, then are denatured the α peptide chains in Hp components, and common electricity can be used after reduction Swimming or isoelectric focusing technique carry out parting, and operation is excessively complicated.Because Hp can be preserved for quite a long time in blood stain, putting into practice In can by detect the Hp in blood stain carry out Classification Identification, but due to hemoglobin excessive in blood stain can cover Hp swimming spectrum, because And the individual identification ability of blood stain is limited to a certain extent.
Therefore have one kind to be supplied easy to operate quick, accurate, the detection hoptoglobin point of clinical practice is can be applied to again The primer pair of type.
