Amino acid N -terminal sequencing , relative molecular weight analysis , amino acid composition analysis , protein purityanalysis , endotoxin content , dihydroxyphenylalanine (DOPA ) content of recombinant mussel adhesive protein were determined by the following methods : Edman degradation , matrix -assisted laser desorption ionization time -of -flight mass spectrometry (MALDI -TOF -MS ), phenyl -isothiocyanate (PITC ), nonreductive SDS -polyacrylamide gel electrophoresis (SDS -PAGE ), gel method , modified Ar⁃now. The efficacy of recombinant mussel adhesive protein was evaluated by cell migration and repairing effect of zebrafish tail fin. Re⁃sults showed that the obtained recombinant mussel adhesive protein was confirmed to be consistent with the theoretical primary structure , protein purity of more than 95%, endotoxin <10 EU ·mg -1, DOPA content above 5%. When the recombinant mussel adhesive protein concentration was 60 μg ·mL -1, the effect of promoting cell proliferation was the most obvious , and it had very significant activity (P <0.01). The caudal fin area of zebrafish in sample group was significantly increased compared with model control group (P <0.001). The results indicated that recombinant mussel adhesive protein can promote cell migration and repair healing and has the potential to be used as biomedical materials.Key words :mussel adhesive protein ; gene recombination ; biological materials ; representation ; efficacy evaluation贻贝粘蛋白(mussel adhesive protein , MAP )也称作贻贝足丝蛋白(mussel foot protein ,Mfps ),收稿日期:2023⁃02⁃24; 接受日期:2023⁃03⁃31联系方式:李敏 E -mail:*******************;*通信作者 侯增淼 E -mail:***********************.cn李敏,等:重组贻贝粘蛋白的表征及功效评价是海洋贝类——紫贻贝(Mytilus galloprovincalis)、厚壳贻贝(Mytilus coruscus)、翡翠贻贝(Perna viri⁃dis)等分泌的一种特殊的蛋白质,贻贝中含有多种贻贝粘蛋白,包括贻贝粘蛋白(Mfp 1~6)、前胶原蛋白(precollagens)和基质蛋白(matrix proteins)等[1]。

Methods A total of 98 patients with type 2 diabetes admitted to Fuzhou Changle District People's Hospital from July 2022 to April 2023 were selected as the study objects and divided into two groups with 49 cases in each group by random lottery method. Both groups were treated with conventional hypoglycemic drugs, the control group was treated with insulin glargine injection, and the observation group was treated with Degu asparton double insulin injection. The clinical therapeutic effect, time of improvement of clinical symptoms, insulin dosage, glucose metabolism index, insulin function index, occurrence of adverse reactions and cardiovascular adverse events were compared between the two groups. Results The total effective rate of the observation group was higher than that of the control group, and the difference was statistically significant (P<0.05).

二、吡唑衍生物的合成吡唑衍生物是一类具有广泛生物活性的化合物,其合成方法多种多样,主要包括直接合成法、重排反应法以及多组分反应法等。

直接合成法通常是通过羧酸与肼或酰肼在加热条件下发生缩合反应来制备吡唑衍生物。

这种方法简单易行,是实验室中最常用的合成方法之一。

在反应过程中,需要选择合适的溶剂和温度,以确保反应的顺利进行。

重排反应法则是通过某些特定结构的化合物在加热或催化剂的作用下发生分子内重排反应,从而得到吡唑衍生物。

这种方法通常需要较高的温度和较长的反应时间,但对于某些特定结构的吡唑衍生物合成具有独特的优势。

多组分反应法是一种高效、快速的合成方法,它可以在一步反应中同时形成多个化学键,从而得到目标产物。

该药物在治疗过程中出现心血管事件较少见,但在临床中早期识别病情变化并警惕重症肌无力患者可能出现的心血管事件非常重要。

因此,我们报道重症肌无力老年女性患者继发于抗胆碱酯酶治疗导致急性心肌梗死并发心源性猝死的病例,并基于此病例对发生心血管不良事件的可能原因进行讨论。

It is commonly treated with cholinesterase inhibitors such as pyridostigmine bro⁃mide. Although cardiovascular events with the drug are rare ,it is very important to early recognize disease changes and be alert to potential cardiovascular events in patients with myasthenia gravis. Therefore , we report a case of an elderly female patient with myasthenia gravis developing acute myocardial infarction and then sudden cardiac death following anticholines⁃terase therapy , and discuss the possible causes of adverse cardiovascular events based on this case.Key words : Myasthenia gravis ; Myocardial infarction ; Pyridostigmine bromide ; Cholinesterase inhibitor重症肌无力(myasthenia ,MG )是一种自身免疫性疾病,通常由针对神经肌肉接头处的乙酰胆碱受体的抗体介导,其特征临床表现为骨骼肌无力和易疲劳[1]。
