One of major subjects that need to be solved.
Quality management is to examine the core of discipline construction.In order to ensure the quality of biochemical investigation result, it is necessary to which biochemistry is examined
Test overall process controlled (Liu Fengchun et al., biochemical investigation quality control, China Health examine impurity, 2010, volume 20:906-
907)。
In biochemical investigation quality control, quality-control product plays key effect.According to the definition of IFCC, quality-control product (also make,
Quality Control object controls substance) refer to sample or solution dedicated for quality control purpose, it is impossible to be used in calibration.Quality-control product is divided into
Two kinds of definite value and underrange.
Quality control procedure is analyzed in clinical biochemical, and the periodic calibration and its quality control of Biochemical Analyzer are must can not
Few, it should all be carried out between new instrument installation, the reagent for replacing different batches, room or after Internal Quality Control appearance exception, each repair
The calibration of instrument.
Quality-control product is the quality control substance for in-vitro diagnosis, is a kind of be intended in the detecting system of medical usage
Substance, material, article or the equipment used, the purpose is to evaluate or confirmatory measurement precision, accuracy of measurement, due to reagent or
The performance characteristics such as the issuable analysis deviation of change detecting system of analytical instrument.
The reliability for the testing result that Biochemical Analyzer is combined with biochemical reagents depends on the monitoring of quality-control product, just can guarantee
Report the accuracy of result and the comparativity of different experiments room testing result.In Clinical laboratory test, it is often necessary to detect sample
Enzyme content/activity in this.However, being compared with small molecule determinand, enzyme is very easy to be denatured.It can be seen that quality-control product
Difference requires very high between stability, bottle.
More than one enzyme is generally comprised in quality-control product.Different enzymes has different chemical property, different activity.Cause
This, requirement of the different enzymes to environment is also different.However, in quality-control product, different types of enzyme is but in same environment, skill
Art personnel are difficult to take into account different enzymes to require the difference of stability.Thus, in the production process of quality-control product, it is intended to add in very
The protective ingredient of multiple types is to meet the needs of different enzymes.
CN102128917A discloses a kind of clinical biochemical quality control products and its preparation process, utilizes trehalose, Duo Zhongwen
Determine agent and the protectant combined effect of compound protein protective agent, complex enzyme, be prepared into multinomial clinical biochemical quality control products.In this application
In, protective agent (4.0 to 6.0g/L sodium chloride, 0.1 to 0.5g/L citric acids, 1.0 to 2.5g/L citric acids is included in quality-control product
Sodium, 0.5 to 1.5g/L sodium dihydrogen phosphates, 0.1 to 0.8g/L adenines, 0.5 to 2.0g/L compound protein protective agents HPD, 1.0 to
5.0g/L dithiothreitol (DTT)s, biological bacteriostatic agent);Stabilizer (6.0 to 16.0g/L mannitol, 5.0 to 10g/L trehaloses, 2.0 to
5.0g/L glycerine, 1.0 to 5.0g/L compound enzymatic protective reagent HP, 2.5 to 6.0g/L compound enzyme stabilizers AES, 1.0 to 2.5g/L
BSA, 0.2 to 0.6g/g sodium azides).This method respectively protects the enzymes such as ALT, AST, TBIL or protein;Have at -20 DEG C
The effect phase is 12 months;It is 6 months that 2 to 8 DEG C, which preserve limited period,.However, added in quality-control product up to 15 kinds it is different types of
Protective ingredient, at least there are the inconvenience of following several respects for this:
1) production cycle is long, and the addition of each ingredient can need to increase corresponding operating procedure,
2) Quality Control Links are increased, each production stage is required for record, monitoring link;
3) uncertainty for chain of tracing to the source is brought;
4) increasing pollution may;
5) production ingredient greatly increases.
A kind of stable quality controlled serum α-hydroxybutyrate dehydrogenase and lactic acid dehydrogenase activity are disclosed in CN101893639A
Method, including to trehalose, mannitol, glycine, quality controlled serum and buffer solution mixing, freeze-drying the step of.
Method disclosed in CN101893639A makes the α-HBDH after freezing and LDH quality-control products preserve for a long time, and two after aquation redissolution
The activity of kind enzyme α-HBDH and LDH are without significant change.In this application, quality-control product includes 3% bovine serum albumin, 12% seaweed
Sugar, 5% mannitol, 200mM glycine, LDH, the phosphate buffer of 400U/L α-HBDH and 550U/L.
For the stability study of visiting reagent, this field predicts the failure period of product frequently with accelerated stability experiment
(for evaluating shelf stabilities, being sometimes referred to as long-time stability or the term of validity).Such method advantage is to study
Cycle is short (usual several weeks), without veritably by reagent storage 1 year, 2 years, even longer time.But acceleration for stabilization
The theoretical foundation of property is Arrhenius formula (Arrhenius equation).In order to ensure the accuracy of prediction, to suitable
With the formula, then there is more requirement to reagent.This is a kind of prediction ideally.However, the ingredient of biochemical reagents
Complexity, species are various, are not that any reagent can ideally be applicable in accelerated stability experiment to predict its real effect phase.
In addition, the stability of reagent should not narrowly be interpreted as shelf stabilities (long-time stability).This be because
It is, reagent in practical operation in use, being not merely to rest among the constant storehouse of environmental condition that (constant is warm and humid
Spend, avoid illumination direct projection, is shockproof), but may be exposed in the environment of variation.For example, it (is carried, top in transportational process
Winnow with a dustpan), the effect of mechanical force can be touched, the variation that can also run into temperature (although cold chain transportation may be employed, can not also avoid
Humiture timing constant).
For another example, in Clinical Institutions, the detection of sample is carried out on large scale equipment (Biochemical Analyzer).This behaviour
As mode multiple samples is allowed sequentially or simultaneously to be detected (from dozens of to a samples up to a hundred).So, reagent will be by steady from it
It spins off in fixed storage condition, and it is for use to open the upper machine of packaging.This process can not equally avoid the variation of humiture,

5. appearance of test case and dissolubility detection
The variation for being completely dissolved time used and course of dissolution is observed after adding in distilled water.
As a result:Each group is white or light yellow freeze-dried powder after lyophilized.Each group is light yellow settled solution after redissolving, nothing
Insoluble matter.
But ALT and AST control groups are completely dissolved needs 11 to 12 minutes.However, the test group of the application is 7 to 10
It is all completely dissolved within minute, the example 7 of especially ALT and AST were completely dissolved within 7 minutes to 8 minutes.This represents this Shen
Test composition please can provide better solubility property, and sample to be tested is more nearly on composition.
6. water content of test case
3 bottles of dried frozen aquatic products is randomly selected, measures the water content of dried frozen aquatic products.
Each group water content is can be controlled within 5% after lyophilized, meets the water content requirement of lyophilized quality-control product.Identical
Under lyophilized operating condition, for the example 6-8 of ALT and AST, water content can be even controlled within 3%.
According to the principle that pressure reduction boiling point declines, the moisture in material can directly distil from water without liquid phase as water
Vapour.Around this principle, first wet feed material can be freezed under freezing point, the moisture in raw material is made to become solid ice, Ran Hou
Under appropriate vacuum environment, ice is converted into steam and is removed, then with the water vapour coagulator in vacuum system by water vapour
Condensation, so that material obtains drying.
Specific theory is not limited to, for the example 6-8 of ALT and AST, composition provides more preferably freezing point, is conducive to
The distillation of moisture in lyophilized physical process.In other words, when being reduced to 5% water content, the quality-control product of the disclosure only needs
Shorter freeze-drying time can reach.
It is poor between 7. homogeneity of test case and bottle
1. homogeneity:1 bottle of replication 10 times measures average, standard deviation and CV by calculating.
It is 2. poor between bottle in batch:Measure 10 bottles of quality-control products each 1 time, it is poor between measure average, standard deviation and bottle to calculate.
As a result:Difference is can be controlled within 5% between each group homogeneity and bottle after lyophilized.However, the reality for ALT and AST
Example 1-8, difference is even can be controlled within 3% between homogeneity and bottle.It is not limited to specific theory, the component kind that control group is added
Class is more, this actually introduces more operational errors, thus affects the controllability of manufacturing process.However, clinically
For between quality-control product bottle-bottle, between batch-batch, it is desirable that more consistent better.Therefore, on the premise of stability is ensured, introducing is got over
Few component (and operating procedure) is better.
The combination quality-control product of test case 8.ALT and AST
In addition, the applicant also combines 400U/L ALT and 400U/L AST according to above-mentioned experiment.With reference to table 1
Composition carry out quality-control product preparation, differ only in addition to 400U/L ALT, also containing 400U/L AST.
Test result shows property indices and the result in test case 1-7 is suitable (data are not shown).This is confirmed
ALT and AST can be prepared into combination quality-control product, and the mutual portion of two kinds of enzymes influences respective stability and biology performance, can exist together
In same composition.
To sum up, in terms of accelerated stability, long-time stability, redissolution refrigeration/redissolution freeze-stable, carried in the disclosure
The lyophilized quality-control product supplied is significantly better than control quality-control product.It also, can when mannitol, galactolipin, glutamic acid are applied in combination
Better effect is provided.
