蛋白质Z与动脉粥样硬化性脑梗死的相关性

目的 观察蛋白质Z（Protein Z,PZ）在动脉粥样硬化性脑梗死（Atherosclerotic cerebral infarction,ACI）患者急性期内的变化,分析PZ与D-二聚体（DD）、纤维蛋白原（FIB）在ACI患者中变化的相关性及血浆PZ的检测在ACI患者中的诊断价值及临床意义.方法 病例组选择发病在72h之内的ACI患者;对照组来自本院健康体检者.所有受检者均于入院即时及入院第14天抽取静脉血测定PZ和相关血凝因素等资料.另采用头颅CT或MRI测量与症状和体征相对应的最大低密度影面积,以及美国国立卫生研究院卒中量表（NIHSS）进行神经功能缺损评分.结果 ACI患者发病3d内血浆PZ、DD、FIB水平明显高于对照组;入院第14天所测的PZ、DD明显高于入院即时所测水平;在诊断ACI的过程中PZ的曲线下面积（AUC）、灵敏度和特异度均高于其他凝血因素,ACI患者血浆PZ浓度与梗死面积及NIHSS评分无相关性.结论 本研究证实了ACI急性期患者体内存在凝血-纤溶系统异常;PZ是脑梗死的一个的危险因素;通过对ACI急性期患者血浆PZ水平及其他血凝因素的检测,结合临床症状、体征及影像学检查,有助于对ACI的诊断和对病情作出判断.     

Organ-specific carcinogenicity of N-methyl-N-nitrosourea in F344 and ACI/N rats

Summary Male and female F344 rats were continuously administered N-methyl-N-nitrosourea (MNU) in their drinking water at concentrations of 200 or 100 ppm, and both sexes of ACI/N rats were given MNU at a concentration of 200 ppm. By the 42nd week of the experiment, high incidences of brain/spinal cord tumors were observed in both strains of rats. Histologically, many of them were astrocytomas or anaplastic astrocytomas. In addition, malignant neurinomas were also detected in the spinal nerve roots and trigeminal nerves, although their incidences were rather low. There was no difference in the type and incidence of these neurogenic tumors between the two strains of rats. Tumors of the tongue and esophagus were mainly observed in the high-dose group of F344 rats and those of the glandular stomach were observed in the low-dose group of F344 rats. In ACI/N rats, tumors of the heart and renal pelvis were detected. The organ-specific carcinogenicity of MNU in these two strains of rats was compared with that of MNU in Donryu rats. It was demonstrated that organ specificity of MNU given orally was influenced not only by the strain of rats but also by the dose level.Part of this work was presented at the 43rd Annual Meeting of the Japanese Cancer Association in Fukuoka, October 1984.

针灸配合松龄血脉康胶囊治疗急性脑梗死疗效观察及对 APN、ET-1 水平的影响

目的:探究针灸配合松龄血脉康胶囊治疗急性脑梗死(ACI)的疗效及对脂联素(APN)、内皮素-1 (ET-1)水平的影响。方法:将62例ACI患者作为研究对象,按随机数字表法分成2组,每组各31例。对照组采用松龄血脉康胶囊治疗,观察组为针灸配合松龄血脉康胶囊治疗;观察2组临床疗效,并比较APN、ET-1、超敏C-反应蛋白(hs-CRP)及纤维蛋白原(FIB)。结果:观察组总有效率高达90.23%,显著高于对照组的64.52%,2组比较,差异有统计学意义(χ^2=5.905,P<0.05)。经治疗,2组治疗后APN显著升高(P<0.05),ET-1、hs-CRP、FIB均下降(P<0.05)。治疗后组间比较,观察组患者APN高于对照组(P<0.05),ET-1、hs-CRP、FIB均低于对照组(P<0.05)。结论:对ACI患者行针灸配合松龄血脉康胶囊治疗,能够显著增加APN水平,降低ET-1水平,且其炎性反应、凝血功能改善效果更为显著。     

急性颅脑损伤患者血清BNP和NSE含量的变化及临床意义

目的：探讨急性脑损伤患者血清脑钠肽（BNP）和神经元特异性烯醇化酶（NSE）含量的变化及其机理和临床意义。方法：采用放射免疫分析对134例急性颅脑损伤患者和40例健康对照者血清BNP和NSE进行测定,并对结果进行统计学分析。结果：颅脑损伤后血清BNP含量显著低于正常对照组,且伤情越重,BNP浓度越低;NSE含量的变化正好与之相反,且两者之间存在明显的负相关（r=-0.674,P〈0.01）。结论：血清BNP和NSE有助于估计急性颅脑损伤患者病情轻重及预后。     

贫血对脑梗死患者预后的影响

目的：探讨贫血对脑梗死患者预后的影响。方法选取2014年8月至2015年9月于我院神经内科收治的脑梗死患者240例,根据入院时血红蛋白检测结果将其分为贫血组与非贫血组,其中贫血组56例,非贫血组184例。比较两组患者的相关临床特点及预后,对影响预后的相关因素进行单因素和多因素分析。结果与非贫血组相比,贫血组患者NIHSS评分更高,年龄更大,冠心病病史、慢性肾衰竭、出血性脑血管病史比例更高,而吸烟及饮酒比例更低,预后更差,差异均有统计学意义(P<0.05)。根据单因素分析结果显示,年龄、NHISS评分、吸烟、慢性肾衰竭、出血性脑血管疾病史、贫血与脑梗死的预后密切相关(P<0.05),多因素Logistic回归分析结显示,贫血(OR=1.017,95%CI 1.005~1.029;P=0.007)、慢性肾衰竭(OR=1.788,95%CI 1.329~2.404;P=0.000)及出血性脑血管病病史(OR=4.315,95%CI 2.504~7.438;P=0.000)是脑梗死预后不良的独立预测因素。结论合并贫血的脑梗死患者预后更差;贫血、慢性肾衰竭及出血性脑血管病病史是脑梗死预后不良的独立预测因素。     

Atypical Fetal Prostate Development is Associated with Ipsilateral Hypoplasia of the Wolffian Ducts in the ACI Rat

For over a half century, the ACI (August × Copenhagen) rat has been a primary model for studying renal agenesis and ipsilateral hypoplasia (IHP) of the Wolffian‐derived structures (WDS). Because the ACI rat is also used as a model for prostate research, it is important to examine the relationship of IHP and urogenital sinus (UGS) development. The prostate is dependent on androgens for proper growth and differentiation. Alteration in androgen production and/or delivery to the UGS has the potential to perturbate normal development. In this study, we investigate whether the ipsilateral loss of the WDS is associated with altered prostate development. Digital images of serial‐sectioned fetal ACI rat UGS were used to create three‐dimensional (3‐D) surface‐rendered models of the developing prostate, seminal vesicle, vas deferens, and utricle on gestational day 21. The number and volume of prostate ducts developing from the UGS were calculated from the 3‐D model data. Animals exhibiting IHP had a significant decrease in total fetal prostate volume (40%; P < 0.005) with significant regional specific differences when compared with normal male ACI rats. Anatomical and histological differences in the utricle, abnormal histology of the ipsilateral testes, and a truncation of the ipsilateral Wolffian ductal mesenchyme were also seen in the animals with IHP. Additional research is needed to further understand the mechanisms and consequences of IHP on prostate growth and development. Alterations to normal prenatal development of the male accessory sex organs can have important consequences for the growth and morphology of the adult gland.

Gentamicin and leucine inhalable powder: What about antipseudomonal activity and permeation through cystic fibrosis mucus?

The aim of this study was to evaluate the permeation properties of gentamicin (G) in a novel dry powder form for inhalation through an artificial mucus model. Moreover, since respiratory infections sustained by Pseudomonas are a major cause of sickness and death in CF patients, the susceptibility of P. aeruginosa to engineered G powders was investigated.
