胸腔镜与传统手术对食管癌的临床疗效与术后体液及细胞免疫功能的影响

目的:探讨胸腔镜与传统手术对食管癌的临床疗效与术后体液及细胞免疫功能的影响效果.方法:收集2014年1月至2017年3月入院的80例食管癌患者随机分为两组,胸腔镜组患者给予胸腔镜手术,传统组患者则给予传统手术,比较两组患者围手术期指标、临床近期疗效、并发症、体液及细胞免疫功能与生活质量.结果:胸腔镜组患者切口长度、术中出血量与总体并发症率均显著性低于传统组,淋巴结清扫个数显著性高于传统组;术后7d IgA、IgG、IgM、CD3+、CD4+、CD4+/CD8+与NK水平组间比较均显著性高于传统组,CRP水平显著性低于传统组;术后12周躯体功能评分组间比较显著性高于传统组,恶心与呕吐、疼痛与呼吸困难评分显著性低于传统组,差异有统计学意义(P<0.01).结论:相比较传统手术,胸腔镜手术的临床效果更为显著,对免疫功能影响较小,具有借鉴意义.     

旱莲草乙酸乙酯总提物对小鼠外周血T淋巴细胞亚群影响

目的 :研究旱莲草乙酸乙酯总提物 (TAEEP)对正常及免疫抑制小鼠T淋巴细胞亚群的作用。方法 :采用正常及腹腔注射环磷酰胺 ( 60mg/kg)所致免疫功能低下小鼠模型 ,给予大、小剂量的TAEEP ,用流式细胞仪测定小鼠血T淋巴细胞CD4 +、CD8+亚群的比例。结果 :大、小剂量TAEEP均显著降低正常小鼠CD4 +亚群的比例 (P <0 .0 1) ,并可显著提高免疫低下小鼠CD4 +亚群比例 ,对于正常小鼠CD8+亚群的比例 ,TAEEP的小剂量可显著降低其比例 (P <0 .0 5) ,而大剂量则显著提高其比例。结论 :旱莲草乙酸乙酯总提物对小鼠外周血T淋巴细胞亚群具有调节作用。

Animal models for neonatal diseases in humans

The development of vaccines for infants and young children requires the use of animal models at various stages of preclinical development. Animal models are being used to assess the quantity and quality of the immune response, onset and duration of the response, induction of systemic versus local immunity, protection against challenge infection for the assessment of vaccine efficacy, as well as safety and toxicity of the vaccine formulation itself. A variety of animal models are available, each with its own specific advantages and disadvantages. Here, we review the most common animal models for preclinical vaccine development for human infants.     

Co-inoculation of baculovirus and FMDV vaccine in mice,elicits very early protection against foot and mouth disease virus without interfering with long lasting immunity

Baculoviruses (Bvs) potentiate the immune response against soluble antigens. We investigated whether Bv could be used as immunoactivator in foot-and-mouth disease (FMD) vaccines using the BALB/c mouse model.     

Herd immunity effect of the HPV vaccination program in Australia under different assumptions regarding natural immunity against re-infection

Deterministic dynamic compartmental transmission models (DDCTMs) of human papillomavirus (HPV) transmission have been used in a number of studies to estimate the potential impact of HPV vaccination programs. In most cases, the models were built under the assumption that an individual who cleared HPV infection develops (life-long) natural immunity against re-infection with the same HPV type (this is known as SIR scenario). This assumption was also made by two Australian modelling studies evaluating the impact of the National HPV Vaccination Program to assist in the health-economic assessment of male vaccination. An alternative view denying natural immunity after clearance (SIS scenario) was only presented in one study, although neither scenario has been supported by strong evidence. Some recent findings, however, provide arguments in favour of SIS.     

DNA–chitosan nanoparticles improve DNA vaccine-elicited immunity against Newcastle disease virus through shuttling chicken interleukin-2 gene

In this study, pCAGG-ChIL2 plasmid DNA containing the chicken interleukin-2 (ChIL-2) gene was used to prepare DNA–chitosan nanoparticles (CNPs). The CNPs prepared were spherical, with mean diameters between 100 and 200?nm, have a positive surface charge, and could protect DNA against DNase I degradation. The CNPs prepared were successfully used to transfect the Df-1 cell line with almost no cytotoxicity. CNPs prepared at an amino group to phosphate group ratio (N/P ratio) of 16 provided the highest transfection efficiency (1.1%) in medium with a pH of 6.5. When pCAGG-ChIL2 CNPs were administered to chickens simultaneously with a DNA vaccine against Newcastle disease virus (NDV), haemagglutination inhibition antibody titers and serum interferon-γ (IFN-γ) levels were significantly higher than in chickens immunised with the NDV DNA vaccine alone (p?<?0.05). The results demonstrate that pCAGG-ChIL2 CNPs improve DNA vaccine-elicited immunity against NDV challenge.
