Description
Technical field
The invention belongs to clinical medical inspection field is and in particular to a kind of be based on double colloidal gold probe detection by quantitative people's bone generations
The colloidal gold strip thanking to mark and the detection means applying it.
Technical background
World Health Organization (WHO) is that bone mineral content is relatively low to the definition of osteoporosises (osteoporosis, op), and skeleton is micro-
Structural change, easily destroyed, skeleton toughness reduces, and is susceptible to fracture.Whole world osteoporosis and relative
Complication and sequela patient reach more than 200,000,000 people.Osteoporotic sickness rate growth rate is accelerated year by year.According to nearest system
Meter, its global incidence comes the 7th of all chronic diseases.
Clinically diagnosis of osteoporosis most common means are bone density (bmd) detections, and most popular method is that dual energy x-ray is inhaled
Receive instrument (dexa) detection.But, the specific standards of bmd yet suffer from larger dispute, and ethnic group, region, sex are to the standard of bmd all
There is certain impact.Additionally, bmd detection is typically all body local detection it is difficult to provide human body comprehensive bone strength information.
Another defect of bmd detection is not good to the Function of Evaluation of osteoporosis therapy effect.The interval of the adjacent detection of bmd twice is
Need 3 months less, therefore cannot react the effect of osteoporosis therapy in time.
Multiple biochemical substances can produce in bone resorption and bone restructuring procedure, and enters into blood, urine or other body fluid.
These materials are referred to as Bone markers.Deepen continuously and many new diagnosing osteoporosis with study to osteoporosises
With the appearance for the treatment of meanss, the degree of concern more and more higher to Bone markers for the people.It is now recognized that Bone markers can
To assess patient bone change over condition, the risk of prediction postmenopausal osteoporosis patients with fractures and assessment patient with bone disease medicine
Curative effect after thing treatment, being one has certain dependency with bmd, but the bone strength phase independent of bmd
Close mark.
Bone markers can be divided into two big class, and bone formation mark, including serum osteocalcin (s-oc), serum bone alkali
Acid phosphatase (s-balp)；Serum t type procollagen n end propetide (s-pinp)；Serum i type procollagen c end propetide (s-picp)；Bone
Absorption marker thing, including Pyridinoline (u-ptd)；Urine i Collagen Type VI crosslinking n terminal peptide (u-ntx)；Urine i Collagen Type VI crosslinking c end
Peptide (u-ctx)；Serum i Collagen Type VI crosslinking n- terminal peptide (s-ntx)；Urinary DPD (u-dpd)；The anti-tartaic acid of serum
Phosphatase 5b (s-tracp-5b)；Serum i Collagen Type VI crosslinking c terminal peptide (s-ctx).
Clinically generally use electro-chemistry immunity method and elisa method detection Bone markers, the detection of both approaches
Overlong time, typically more than 45 minutes, the detection time of elisa method is typically at 1 hour for the detection time of electro-chemistry immunity method
More than 30 minutes.And, the operation of both the above method is complex, need the reviewer of specialty could operate.
