EDQM
The European Directorate for the Quality of Medicines (EDQM) has originated from the European Pharmacopoeia Secretariat which, with the addition of new responsibilities changed its name to the European Department for the Quality of Medicines (EDQM). The EDQM sits alongside the European Medicines Agency (EMEA).
Amongst other activities, the EDQM is responsible for the European Pharmacopeia and the issuing of Certificates of Suitability (CEP).
Certificates of Suitability (CEP) are recognised by all signatory states of the European Pharmacopoeia Convention and by the European Union. Other countries have also chosen to recognise them. In the case of Fetal Bovine Serum and other Bovine Serum a CEP can be used by the manufacturers of Fetal Bovine Serum and other Bovine Serum which is intended for use in the manufacture of pharmaceutical products to demonstrate compliance with the Bovine Serum monographs of the European Pharmacopoeia and the EDQM requirements for substances concerned by TSE risk.
The discovery of Bovine Spongiform Encephalopathy (BSE), which is one of a group of similar infections now referred to as Transmissible Spongiform Encephalopathies (TSEs), and it’s spread over many countries of the European Union as well as its discovery in Canada, the USA and Japan is well known. The European events provided the impetus for the Council of Europe Public Health Committee (CEPHC) to pass Resolution AP-CSP (99) 5 addressing the TSE concerns and creating a Certificate of Suitability (COS) pursuant to Directive 75/318/EEC.
The granting of a CoS to a manufacturer, for a particular product, certifies that the product in question has been assessed for the level of risk of transmission of TSEs, and that the risk level is considered low enough that the product is certified as suitable for use in the manufacture of medicinal products in the European Union.
The process of approval requires the manufacturer to submit a dossier that covers all relevant aspects of the collection of raw material and further processing that is performed to reach the product that is offered to end users. This dossier is detailed and covers the specific material that is collected, the collection method, process validation, testing, traceability, quality systems and an expert review.
Only after this dossier has been examined and approved by two rapporteurs and, if necessary, by a panel of experts appointed by the European Directorate for the Quality of Medicines (EDQM) is the manufacturer granted a COS.
Moregate Biotech has been granted a COS for:
- Fetal Bovine Serum – Australian Origin – CEP2000-187
- Fetal Bovine Serum – New Zealand Origin – CEP2000-188
- Adult Bovine Serum - New Zealand Origin – CEP2001-093
- Adult Bovine Serum (Defibrinated) - New Zealand Origin – CEP2000-174
- Bovine Plasma – New Zealand Origin – CEP2003-199

1)提供基本营养物质:氨基酸、维生素、无机物、脂类物质、核酸衍生物等,是细胞生长必须的物质。
2)提供结合蛋白:结合蛋白作用是携带重要地低分子量物质,如白蛋白携带维生素、脂肪、以及激素等,转铁蛋白携带铁。结合蛋白在细胞代谢过程中起重要作用。
3)提供激素和各种生长因子:胰岛素、肾上腺皮质激素(氢化可的松、地塞米松)、类固醇激素(雌二醇、睾酮、孕酮)等。生长因子如成纤维细胞生长因子、表皮生长因子、血小板生长因子等。
4)对培养中的细胞起到某些保护作用:有一些细胞,如内皮细胞、骨髓样细胞可以释放蛋白酶,血清中含有抗蛋白酶成分,起到中和作用。这种作用是偶然发现的,现在则有目的的使用血清来终止胰蛋白酶的消化作用。因为胰蛋白酶已经被广泛用于贴壁细胞的消化传代。血清蛋白形成了血清的粘度,可以保护细胞免受机械损伤,特别是在悬浮培养搅拌时,粘度起到重要作用。血清还含有一些微量元素和离子,他们在代谢解毒中起重要作用,如SeO3,硒等
5)提供促接触和伸展因子使细胞贴壁免受机械损伤。
6)血清中有抗体,这是被称作免疫球蛋白的蛋白质,血清可以抗病毒,增强抵抗力血清属于生物制剂。

结果:
RESULTS:
各组血清25(OH)D浓度普遍较低。
Serum25(OH)Dconcentrationsweregenerallylowinallgroups.
与对照组(28.1±6.6ng/mL,8%)、普通组(29.5±8.1ng/mL,10%)和重症组(31.9±9.7ng/mL,8%)相比,危重组患者血清25(OH)D平均浓度(20.0±8.4ng/mL)明显较低,血清25(OH)D缺乏比例(18%)明显较高(P<0.05)。

在危重组中,25(OH)D缺乏组比25(OH)D正常组及不足组具有更低的PCIS值(P<0.05);而比后两组具有更高LAC、LDH、CK-MB和DD;具有(更高的)脑干脑炎、神经源性肺水肿、循环衰竭发生率及病死率(P<0.05)。

死亡组较存活组具有显著降低的血清25(OH)D浓度和PCIS(P<0.05),具有较高的LAC、LDH、CK-MB和DD水平;较高的脑干脑炎、神经源性肺水肿、循环衰竭发病率(P<0.05)。

Logistic回归分析显示,血清25(OH)D浓度是影响重症手足口病患儿病死率的独立因素。

CONCLUSIONS:
结论:
在这项研究中,我们发现,血清25(OH)D浓度在手足口病危重患儿中大幅降低,并与手足口病的严重程度相关。
Inthisstudy,wefindtheserum25(OH)DconcentrationsaresubstantiallyreducedinchildrenwithcriticalandsevereHFMDandareassociatedwiththeseverityofHFMD.
血清25(OH)D浓度对判断重症手足口病进展和预测死亡风险具有临床价值。

在确定25(OH)D浓度在手足口病诊断的临床价值之前,仍需进一步的证据。

血浆是由抗凝的血液中分离出来的液体,其中含有纤维蛋白原,若向血浆中加入Ca2+,血浆会发生再凝固,因此血浆中不含游离的Ca2+.血清是由凝固的血中分离出来的液体,其中已无纤维蛋白原,但含有游离的Ca2+,若向其中再加入Ca2+,血清也不会再凝固.此外,血浆与血清的另一个区别是:血清中少了很多的凝血因子,以及多了很多的凝血产物.
