open access: yesLinchuang shenzangbing zazhi, 2019
目的观察慢性肾衰竭维持性血液透析(MHD)患者在N5,N10-亚甲基四氢叶酸还原酶(MTHFR)基因多态性指导下的个体化服用叶酸治疗纠正高同型半胱氨酸血症的效果。方法研究纳入93例一般状况稳定的MHD患者,分为普通治疗组和个体化治疗组。两组患者均行低通量透析,并在研究期间透析器和血流量保持前后稳定。在透析治疗基础上,普通治疗组患者均口服叶酸15 mg/d,个体化治疗组依据患者MTHFR基因型决定叶酸用量,纯合子突变型(TT)、杂合子突变型(CT)和野生型(CC)患者分别口服叶酸剂量为30 mg/d、15

通过主动诱导移植物抗宿主病使AML1-ETO基因转阴1例并文献复习

open access: yesZhongguo shiyan zhenduanxue, 2023
异基因造血干细胞移植(allo-HSCT)是目前高危组急性髓系白血病(AML)唯一可以根治的治疗手段[1]。然而,移植后复发仍是allo-HSCT后患者死亡的最主要原因[2]。通过微小残留病(MRD)监测及时发现MRD并给予抢先治疗可以有效预防移植后复发,提高长期生存率[3]。目前对于移植后MRD阳性患者的干预手段主要有供者淋巴细胞输注(DLI)、去甲基化治疗、靶向药物治疗、干扰素(IFN)等,但仍有部分患者疗效不佳[4-5]。

The influence of zCep85 and zNek2 on the early embryonic development of zebrafish [PDF]

open access: yes, 2016
zCep85是哺乳动物中心体结合蛋白Cep85在斑马鱼中的同源蛋白,其靠近C端的部分具有一个coil-coiled功能域,这是大部分中心体结合蛋白共有的结构。目前对zCep85的研究尚浅,本实验室早期报道显示,哺乳动物细胞中hCep85特异性地拮抗hNek2,使得细胞停滞于G2/M期。但是,我们对其在脊椎动物胚胎发育中的功能依然所知甚少。为了深入探究zCep85在发育中的作用,本课题以斑马鱼(Daniorerio)为动物模型从基因结构、表达谱、功能分析等方面研究了zCep85在胚胎发育中的作用。此外 ...

Chemical Stability of Ceftazidime Compounded in Saline, Glycerin and Dexamethasone‐SP Solutions Stored at −20°C, 4°C and 25°C Over a 60 Day Period

open access: yesVeterinary Dermatology, Volume 36, Issue 6, Page 862-869, December 2025.
ABSTRACT Background Chronic cases of canine otitis externa (OE) often develop infections with Pseudomonas aeruginosa (PA). Given the organism's high level of resistance, veterinary surgeons often turn to compounded solutions. Limited data describing the stability and potency of compounded ceftazidime (CAZ) solutions are available, which may affect ...

Extraction of biopharmaceutical plasmid DNA by reversed micelles [PDF]

open access: yes, 2006
质粒DNA作为生物药剂(尤其作为基因治疗和基因疫苗的载体)的意义和需求越来越大。质粒DNA作为一种新的非病毒转基因载体,优点是安全可靠、稳定、对外源基因的容纳量大、不会引起免疫系统反应及易于生产等。随着基因治疗和DNA疫苗从实验室进入临床研究和批准上市,必须开发出一个经济、简单以及高重复性的质粒分离纯化生产工艺,使其质量达到临床应用的标准。近年来,国外针对生物药剂质粒DNA的分离纯化,开发了机械破碎、碱法裂解等工艺破碎细胞释放质粒,离心或过滤分离细胞碎片、变性蛋白和核酸 ...
