Description
Technical field
The invention belongs to pharmaceutical technology fields, and in particular to it is a kind of identify carcinoma of endometrium biomarker method and
Its detection kit.
Background technique
Carcinoma of endometrium is the most common feminine proses, is apt to occur in climacteric and postmenopausal women.According to beauty
Cancer association of state estimates to be diagnosed carcinoma of endometrium there are about 320,000 women and cause 76,000 people dead for 2012.This makes
It becomes the second largest female reproductive system malignant tumour after cervical carcinoma.Endometrial biopsy and Transvaginal Ultrasound inspection combination
Be standard carcinoma of endometrium preoperative diagnosis detection methods.In addition there are CT scan, Magnetic resonance imaging, the skills such as biopsy
Art, but cannot all provide diagnostic result.Most common clinical detection marker is carbohydrate antigen in blood test
CA125, people's epididymal proteins 4 (HE4), but its sensitivity is lower, is not easy effective screening patient.These diagnostic methods can bring one
Fixed drawback.Therefore, a kind of convenience is found, the detection method of hurtless measure is very necessary.And optimal is exactly to be not required to live
Inspection, and sensitivity and specific high serum analysis.

Degree.The concentration range of free mannose is 20~80 μm of ol/L in health adult's blood plasma.The content of mannose is about that glucose contains
The 1% of amount.Its major part is considered as from the glucose isomerization in cell.And some researches show that flow in cell recently
Free mannose out is the main source of free mannose in mammalian.The free mannose in this two parts source
Maintain the stabilization of mannose in serum.D-MANNOSE is glycoprotein, cell surface glycoconjugates and glycolsyl-phosphatidylinositol
Required monosaccharide in the structures such as anchorin.Wherein, mannose is the important component of N- sugar chain in various polysaccharide compounds, and N- is poly-
Glucose or mannose of the mannose residue in blood in sugar.Free mannose is normal plasma composition.Currently,
The measuring method of serum mannose mainly has enzyme process, gas-liquid chromatography, high resolution liquid chromatography, gas-liquid chromatography-mass spectrography and hair
Cons electrophoresis method etc..But there is certain shortcoming in these methods.For example, using enzyme process, gas-liquid chromatography and high-resolution
When liquid chromatography, to avoid the influence needs of glucose of high concentration from removing it, cause pretreatment process comparatively laborious；Gas-liquid
Chromatography mass spectrometry instrument price is expensive, is not suitable for routine purpose；Required serum sample amount is big.Before document report column
High performance liquid chromatography derived from 1- phenyl -5- methylpyrazole quinoline ketone (PMP) detects endometrial carcinoma serum middle reaches simultaneously
From mannose and glucose.
