Abstract
The invention relates to a compatible application method of methionine and puerarin, which is characterized in that the methionine and the puerarin are prepared into an injection containing the puerarin, or the methionine is firstly used and then the puerarin is used, thereby effectively overcoming the accidental hemolytic adverse reaction of the puerarin injection and improving the safety of the puerarin injection administration.
Description
Technical Field
The invention relates to a medical application of methionine, in particular to an application in puerarin injection.
Background
The methionine is taken as a substrate for protein biosynthesis and can directly participate in the synthesis of proteins of organisms, and the methionine can be activated to generate S-adenosyl methionine (SAM) which is taken as a donor of methyl and sulfydryl, participates in the methylation of DNA, RNA, protein and the like in vivo and also participates in the synthesis of a plurality of bioactive substances such as polyamine, cysteine, glutathione, taurine and the like, thereby regulating and controlling the main physiological functions of animals. Reactive oxygen species (reactive)
oxidative species, ROS) can cause an imbalance in oxidative and antioxidant effects, leading to lipid peroxidative damage to proteins and DNA, which in turn leads to cell damage or apoptosis. Methionine exerts an antioxidant function in vivo mainly through a glutathione pathway and a redox pathway, and through the regulation of the production of antioxidant metabolites such as taurine and H2S in a transsulfuration pathway. Methionine regulates the immune state of the body by promoting the growth and development of immune organs, the proliferation of immune cells, and the involvement in the synthesis of immune molecules (cytokines, antibodies, complement, etc.). The lack of methionine promotes the apoptosis of the porcine epithelial cells infected with the ETEC, and simultaneously shows the characteristics of enhanced adhesion with the ETEC, reduced autophagy and the like. The methyl donor SAM in the methionine cycle promotes the development and functional expression of cells by participating in the methylation modification of proteins and nucleic acids. SAM can regulate the production and expression of some key cytokines such as TNF, IL-10 and IL-6, and can promote the proliferation activation of Th cells by relieving the reduction of caspase-3 activity induced by oxidative stress and reducing apoptosis, thereby participating in specific and non-specific immune responses.
Puerarin is an isoflavone compound extracted from dried root of Pueraria lobata Ohwi of Leguminosae, 4', 7-dihydroxy-8-beta-D-glucosyl isoflavone. Is widely used for treating cardiovascular diseases clinically. The prior clinical medicine preparation containing puerarin is mainly injection. With the wide use of puerarin, more and more reports about adverse reactions of puerarin are provided in recent years, and the wide attention of the medical field is attracted. By analyzing the adverse reaction of the traditional Chinese medicine in the last 20 years, the puerarin injection is ranked at the 18 th position. The national adverse drug reaction monitoring center reported adverse reactions of puerarin injection in adverse drug reaction information report 3 of 1 month in 2003. Most researchers think that the puerarin injection is prepared by using 50% propylene glycol as a solvent, so that the purity is not enough due to the difference of extraction processes, technologies and the like, and various reactions caused by introducing impurities cannot be avoided (see the analysis of adverse reactions in clinical puerarin injection in xu daohui, Shanghai J.Med., 2006, 40 (8): 71-72; and the clinical application and adverse reactions of puerarin in Xu Shi Guo, Shizhen Chinese medicine, 2005, 16 (12): 1307-1308). After 63 adverse reactions of puerarin reported in main medical journal in 2004 in 2000-year, 40 men and 23 women were discovered; the age is 34-81 (57.5 +/-23.5). In all cases intravenous drip was administered. The administration dosage is 0.4-0.6 g, and the drug diluent is 5% glucose solution, normal saline, 5% glucose saline and the like. The fastest reaction time is 3 min, the slowest reaction time is 13 d, and the reaction time is in the administration process. 47 responders appeared with the first dose and 16 responders appeared with repeated doses. Statistics show that the common adverse reactions include allergy (fever, tremor and the like, 24 cases), anaphylactic shock (4 cases), hemolytic anemia (13 cases), liver damage, kidney damage (7 cases), drug fever (10 cases) and death (5 cases). All cases had no history of allergy, and the patients who stopped taking the drug after the reaction were recovered by symptomatic treatment (except dead cases). The dosage and the used diluent are within the prompting range of the medicine instruction, and all reactions are definitely caused by puerarin. The adverse reaction is independent of the disease, age and sex, and is not related to the drug diluent. It is related to the difference in constitutions of patients, especially the elderly and infirm. The length of the reaction time is related to the slow onset of action of the Chinese medicinal preparation (see the general Rongrong written analysis of 63 cases of adverse reactions of puerarin documents, journal of the modern Chinese and Western medicine combination, 2005, 14 (1): 140). A patient with intravenous injection of puerarin shows acute renal insufficiency and hemolytic anemia after about 10min (see Kunming written "puerarin induced hemolytic anemia", journal of adverse drug reactions, 2003, 5: 291). Therefore, the hemolytic anemia caused by puerarin is caused by puerarin itself.

The hemolysis experiments were performed separately. 10mL of blood is collected from the heart of each rabbit, 160IU of heparin sodium (Jiangsu Wanbang Biochemical medicine, Inc.) is anticoagulated, then the rabbit is placed in a graduated centrifugal tube, the rabbit is centrifuged at 2000 r/min for 10min, the blood plasma is discarded, a proper amount of sodium chloride injection is added for washing, and the rabbit is centrifuged to discard the supernatant and the leucocyte layer. Adding appropriate amount of normal saline, shaking, centrifuging, and repeatedly washing for 3 times until the supernatant is colorless and transparent after centrifuging. The packed red blood cells were diluted with physiological saline to form an 11% (by volume) red blood cell suspension. This completes the preparation of the red blood cell suspension.
2.2 Puerarin solution in vitro hemolysis experiment design
Let the concentration of puerarin solution on erythrocytes be 6mM (0.00259 g.mL)-1). Setting a negative control group, a solvent control group (DMSO is used for replacing puerarin solution to act on erythrocytes), a drug treatment group and a positive control group. The puerarin solution was measured to have a pH of 7.16 using a METTLER TOLEDO benchtop pH meter.
The corresponding components were added to the tubes separately, taking care of the order of addition, as shown in Table 1 below. After each addition of one ingredient, shake gently. After all the components in the system are added into the system, the mixture is gently shaken and uniformly mixed, and then the mixture is placed in a biochemical incubator at 37 ℃ for incubation. After 10min hemolysis and coagulation reactions were observed. The condensation reaction determination method comprises: if the solution has reddish brown or brownish red flocculent precipitate, it will not disperse after shaking, indicating that there is agglutination of red blood cells, if the aggregate can be uniformly dispersed after shaking, it will be false agglutination, if the aggregate is not shaken, it will be true agglutination. The tubes were then centrifuged at 5000rpm/min and the color of the supernatant visually observed. The supernatant was collected and the light absorption (OD value) was measured at a wavelength of 540 nm. According to 2005 technical guidance principle of stimulation and hemolysis research of traditional Chinese medicine and natural medicine, the hemolysis rate (%) of each tube of each group is calculated according to a formula:
hemolysis rate (%) = (drug-treated OD value-negative control OD value)/(positive control OD value-negative control OD value)
Reference evaluation criteria: the hemolysis rate >5% indicates that hemolysis occurred and was statistically processed.
TABLE 1 puerarin solution and methionine in vitro hemolysis experiment grouping design
3 results
The puerarin is 15 mg/kg daily according to body mass－1When the dosage is treated, 15 mg.kg is simultaneously administered－1At the dose of methionine, no hemolysis was found in the experimental rabbits. The test also considers the influence of 40 mu M, 20 mu M and 10 mu M methionine on 5 rabbit red blood cells injected with puerarin when the concentration of the puerarin is 6mM, and simultaneously carries out the occasional hemolysis experimental study of the puerarin injection of the fourth and fifth, and the experimental results are all recorded in detail. By X2The results of the test statistical analysis are shown in Table 2.
Note: a P <0.01 compared to saline negative group; b P <0.01 compared with puerarin injection group
The results show that: the saline group showed no hemolysis, and the water for injection showed complete hemolysis: compared with the normal saline group, the puerarin Injection (IV) and (V) are all hemolyzed, and the occurrence rate of hemolysis is very different from that of the normal saline group (P is less than 0.01); the results of the hemolysis test are reproduced, which shows that the hemolysis test method is stable and reliable, and the test results can be repeated. Comparing with the fourth and the fifth groups of puerarin injections, the compound puerarin injections (P <0.01) have no hemolysis in the groups of (VI), (III; compared with the normal saline, the hemolysis incidence of each group of compound puerarin injections (P >0.05) and (b) does not differ from that of the normal saline; the compound puerarin injections (sixty percent, nine, eight, 11) have the same puerarin concentration (6 mM), but the compound puerarin injections (sixty percent, nine, seven, eight, nine) contain 40 muM, 20 muM and 10 muM methionine, and the puerarin (sixty percent, seven) do not contain methionine. The above results suggest: the methionine with different concentrations and the puerarin can resist hemolytic adverse reaction induced by the puerarin and reduce the incidence rate to the normal saline level.
The above experimental results show that: the puerarin can initiate hemolysis, the injection containing the puerarin can initiate hemolysis, and the hemolysis adverse reaction containing the puerarin can be eliminated after the methionine is added.
The above test results suggest: the puerarin injection and the injection prepared by the puerarin and the methionine have no hemolytic reaction.
Therefore, when the puerarin-containing injection is prepared or used, the methionine is added, so that hemolytic adverse reactions caused by the puerarin can be eliminated, and the safety of puerarin injection administration is improved.
The invention has the advantages that: when the puerarin-containing injection is prepared or applied, methionine is added, so that the injection has better antagonism to intravascular hemolysis adverse reaction induced by puerarin, and has the advantages of low price, no toxic or side effect and safety.
