黄芪建中汤对慢性阻塞性肺疾病稳定期大鼠呼吸肌疲劳影响的实验研究

目的 研究黄芪建中汤对慢性阻塞性肺疾病(chronic obstructive pulmonary disease, COPD)稳定期模型大鼠呼吸肌疲劳的影响。方法 取SD大鼠120只，随机分为6组：空白对照组，模型组，黄芪建中汤高、中、低剂量组，金水宝组，每组20只。采用熏吸香烟并气管内注入脂多糖法复制大鼠COPD模型。连续治疗8周后观察各组大鼠膈肌超微结构，测定膈肌线粒体还原型尼克酰胺腺嘌呤二核苷酸氧化酶（reduced form of nicotinamide adenine dinucleotide oxidase, NOX)、琥珀酸脱氢酶（succinodehydrogenase, SDH）、细胞色素氧化酶（cytochrome oxidase, CCO）的活性。结果 模型组大鼠膈肌细胞线粒体肿胀变性，数量减少甚至消失形成空泡，肌原纤维走向紊乱，局部肌丝溶解消失。各治疗组膈肌组织超微结构改变均较模型组明显减轻，以黄芪建中汤高剂量组的作用为最优。模型组NOX、SDH、CCO活性显著低于空白对照组（P<0.01）；黄芪建中汤呈剂量依赖性地升高COPD大鼠膈肌线粒体NOX、SDH、CCO活性（P<0.05，或P<0.01）。结论 黄芪建中汤可明显修复COPD模型大鼠膈肌线粒体结构，剂量依赖性地升高膈肌线粒体NOX、SDH、CCO活性，从而延缓COPD的进程。

鸡传染性法氏囊病灭活疫苗免疫鸡中和抗体效价与攻毒保护力的相关关系

为了探讨鸡传染性法氏囊病病毒中和抗体效价与攻毒保护力的相关关系,以不同剂量的鸡新城疫、传染性法氏囊病二联灭活疫苗免疫21日龄的SPF鸡,免疫后采血测定鸡传染性法氏囊病病毒中和抗体,并用传染性法氏囊病病毒强毒攻击,攻毒后第72小时,剖检所有试验鸡,观察鸡法氏囊等器官病变。将每只试验鸡的传染性法氏囊病病毒中和抗体效价与攻毒保护情况进行一一对照。结果显示,当传染性法氏囊病病毒的中和抗体效价≥1∶16 384(214)时,可获得100%的保护;效价为1∶8 192(213)时,保护率为95.5%;效价为1∶4 096(212)时,保护率为92.9%;效价为1∶2 048(211)时,保护率为86.1%;效价为1∶1 024(210)时,保护率为76.5%;效价为1∶512(29)时,保护率为53.3%;效价为1∶256(28)时,保护率为33.3%,效价≤1∶128(27)时,保护率为0。试验证明,鸡传染性法氏囊病病毒中和抗体效价与攻毒保护力密切相关。     

新城疫病毒强弱毒株LAMP鉴别检测方法的建立

根据新城疫病毒(NDV)融合基因(F基因)的8个区域设计能区分强、弱毒株的3套特异性引物,以样品的cDNA为模板,利用Bst DNA聚合酶,在62℃恒温下进行扩增,扩增产物中加入SYBR GreenⅠ染料直接或在紫外光下观察判定结果,建立了能鉴别检测NDV强、弱毒株的环介导等温扩增方法。该方法可区别不同基因型的NDV强、弱毒株,而对常见鸡源病毒均无扩增反应。该方法对NDV RNA的最小检测限为0.01pg,灵敏度是常规RT-PCR方法的100倍。该方法无需特殊仪器,只需在常规水浴锅中进行,是一种适于基层的简便、灵敏、快速的NDV强、弱毒株鉴别检测方法。     

Academic Achievement and the Self-Image of Adolescents with Diabetes Mellitus Type-1 and Rheumatoid Arthritis

A total of 69 adolescents, 21 with diabetes mellitus type-1 (DM), 24 with rheumatoid arthritis (RA), and 24 controls matched for sex, age, social background, and living environment, were compared by means of their school grades and the Offer Self-Image Questionnaire. The ages of the children at the time of the diagnosis of the disease and its subsequent duration were the same in the DM and the RA groups. Results show that the academic achievement of adolescents with DM who are well balanced and adolescents with RA with mild or moderate symptoms are equal to those of their healthy peers. In the OSIQ scales there were no statistically significant differences between the groups. In the groups of controls, there were more significant correlations between the OSIQ scores and the school grades than those with the DM or RA adolescents. The direction was positive. The correlations of the 3 groups did not differ significantly from each other. In case of adolescents with various kinds of chronic diseases, it is important to support their motivation for learning and planning the future.Medical doctor, specializes in child and adolescent psychiatry.

IBDV感染鸡免疫器官淋巴细胞中细胞凋亡调控蛋白的动态表达

用鸡传染性腔上囊病病毒(IBDV)SNJ93株、BC6/85株、B87株感染SPF鸡后观察免疫器官淋巴细胞中Bcl 2和Bax蛋白的分布定位和动态变化。结果,B87株接种组的腔上囊、脾、胸腺淋巴细胞中这两种蛋白在各检测时间均为阴性反应;SNJ93与BC6/85攻毒组胸腺淋巴细胞中这两种蛋白呈现阴性反应,SNJ93攻毒组腔上囊和脾淋巴细胞在48h即开始出现Bcl 2和Bax阳性反应,腔上囊淋巴细胞内这两种蛋白在感染后72、96、120h呈现明显的强阳性反应,以后开始降低,脾淋巴细胞中这两种蛋白在感染后72、96h出现强阳性反应;BC6/85攻毒组腔上囊淋巴细胞中只在96、120h出现阳性反应,脾淋巴细胞中只在96h呈现阳性反应。用免疫组化法检测Bax和Bcl 2,有可能为IBDV毒力划分增添新的依据。     

Myxoid heart disease: A review with special emphasis on sudden cardiac death

Myxoid heart disease (MHD), more commonly known as mitral valve prolapse, is a very common caridac abnormality affecting 5–10% of the general population. This article reviews the history, symptoms, physical findings, pathology, associated conditions and complications of this entity. Special emphasis is given to sudden cardiac death, which occurs as a result of acute heart failure or due to a fatal arrhythmia. Theories regarding the origin of the arrhythmias are discussed. Once the origin is known, those at risk for this devastating complication can be identified and perhaps a preventative therapeutic regimen developed.

我国医疗保障法律制度相关问题研究

目前,我国全民医保体系已初步形成,但仍面临医疗保障互助共济功能尚未充分发挥,医疗保障法律制度立法层级较低,应急医疗保障法律制度欠缺,大病保障制度的法律归属不明晰,医疗保障法律制度衔接存在障碍等问题。因此,应在坚持医疗保障立法的社会连带理念、明确法律体系建设目标的基础上,加快提高立法层次,建立统一的应急医疗救助法律制度,明确重大疾病保险的法律属性,完善多层次的医疗保障法律制度体系。     

致猪水肿病大肠杆菌标准菌株F107/86 fedA基因的克隆与原核表达

以致猪水肿病大肠杆菌标准菌株F107/86的基因组DNA为模板,对去掉信号肽的456bp的fe-dA基因进行了PCR扩增,将其克隆到原核表达载体pGEX-6P-1的BamHⅠ与EcoRⅠ位点之间,经酶切鉴定与测序,在大肠杆菌中以IPTG诱导表达,并对表达产物用SDS-PAGE和Western-blot分析进行验证。结果表明,筛选出的阳性质粒pGEX-fedA-2(pfedA)经测序并与GenBank中收录的M61713序列进行比较,证明插入序列及读码框正确;表达产物GST-FedA经SDS-PAGE分析大小约42.4ku,Western-blot分析证实其具有良好的反应原性。所构建的原核表达载体可大量表达抗原蛋白,为进一步研究猪水肿病亚单位疫苗奠定了基础。
