提出了基于 BP的改进环形反向传播网络模型 (Improved circular back- propagation)。与环形反向传播网络模型 (Circular back- propagation)相比 ,ICBP所含的可调参数几乎不变 ,但却蕴含着较 CBP更灵活的超椭球分界面 ,显示出了其较强的表达能力和适应能力。本文构造性地证明了ICBP与矢量量化网络的等价性。实验结果证实了其可行性并表明在分类问题中此构造方法有其实际意义。

In this paper, gradually searched method is introduced. The minimum system of total fare is used to optimize allocation of reliable degree for exciting system. The exciting system is separated into four units. According to the using requirement, the reliable degree of the system keeps not less than 0.97 after two years using. So the question of the optimized allocation of reliable degree becomes to make the total fare ck minimum based on the reliable degree of the system not less than r. The parallel number of each unit is the blue print of the optimized allocation of reliable degree for exciting system.

目的对重型肝炎中肝前体细胞的某些标志物进行检测以明确其存在并探讨其在不同病理类型肝组织中的分布范围及特点。方法采用免疫组织化学的方法分别对59例重型肝炎病例肝组织标本表达干细胞因子受体(c-kit)、谷胱甘肽S转移酶π(GST-π)、白细胞分化抗原34(CD_(34))、细胞角蛋白19(ck19)、细胞角蛋白18(ck18)、甲胎蛋白(AFP)的情况进行检测。同时,对58例急慢性普通肝炎病例进行检测作为对照。结果在重型肝炎中存在肝前体细胞,大部分以管状细胞即非典型胆管增殖(ADP)的形式存在,多位于门静脉汇管区、纤维间隔、汇管区或假小叶周边肝实质及炎症灶的周围,可表达c-kit、GST-π、ck19及ck18,而CD_(34)和AFP为阴性;一部分以小肝细胞样细胞的形式存在,可表达c-kit、GST-π及ck18,而ck19、CD_(34)及AFP为阴性。重型肝炎ADP范围明显大于普通肝炎(x^2=63.63,P<0.05),亚急性重型肝炎和慢性重型肝炎病例ADP范围明显大于急性重型肝炎病例。结论在病毒性肝炎的再生过程中,不同病理类型的特点也不同。普通型肝炎和慢性肝炎轻度主要是以肝细胞的增殖为主,在慢性肝炎中重度有肝前体细胞的参与,而在重型肝炎中,肝细胞的增殖受到损害或抑制,肝脏主要是通过肝干细胞的活化和增殖进行再生。

研究人员对来自西班牙(n=3)和丹麦(n=10)13家感染断奶后多系统衰竭综合征(PostweaningMuhisystemic Wasting Syndrome,PMWS)的猪场进行了2项前瞻性纵向研究.猪的血液样本从第1周开始纵向采集直到爆发PMWS为止.相同日龄的健康或衰竭性猪都进行安乐死、尸体解剖和组织病理学描述.通过淋巴病变、原位杂交或免疫组织化学方法检测这些组织中的PCV2,从而确诊PMWS.血清分析在纵向采集的血清样本中进行,以检测针对PCV2、猪繁殖与呼吸综合征病毒(Porcine reproductive And respiratory Syndrome Virus,PrrSV)、猪细小病毒(Porcine ParvoVirus,PPV)、猪流感病毒(Swine Influenza Virus,SIV)、细胞内罗森氏菌(Lawsonia intracellularis,law)、猪肺炎支原体(Mycoplasma hyopneumoniae)、猪伪狂犬病病毒(Aujeszky's Disease Virus,ADV)和沙门菌(Salmonella spp.)的抗体.Cox比例风险模型(Cox proportional hazards model)被用来研究血清转换和抗所研究病原体母体免疫的同步效应.

支架置入术后心肌损害的预测因子和预后价值

世界核心医学期刊文摘（心脏病学分册） 2005年第2期1卷 44-45页

作者： ramrez Moreno A. Cardenal r. Pera C. 艾文婷 Servicio de Cardiologa Complejo Hospitalario Cd. de Jaen Avda Ejercito Espanol 10 23007 Jaén Spain

Background: Troponin I concentrations are frequently elevated following percut aneous coronary intervention(PCI) even in procedures without complications and a re considered, by some, as predictive of long term morbidity and mortality. We assessed whether post PCI troponin I concentrations bore any relationship to cl inical, angiographic and in laboratory minor adverse events indicative of myoca rdial injury and evaluated, in follow up, whether these levels are useful as a predictive markers of adverse events. Methods: Patients(n=147) who were schedule d for PCI for stent placement were prospectively studied. In laboratory events recorded were protracted chest pain, electrocardiographic changes, slow flows, d issections and lateral branch affectation. Troponin I and creatinine kinase MB f raction (ck MB) mass were measured at baseline and postprocedure. Mean clinical follow up was for 10.4±3.6 months. results: During PCI, at least one adverse event occurred in 34%of patients and, in 38%of them, there was an elevation of troponin I as compared to 5.1%of those patients without any adverse event (rel ative risk=7.4; Proponin I concentrations occurred in 16 .3%of all patients, 79.2%associated with an AE. ck MB was elevated in 15.6%o f patients. On multivariate analysis, protracted chest pain, lateral branch invo lvement and slow flow remained statistically significant in relation to post pr ocedure elevations of troponin I concentrations. Clinical follow up showed a po orer prognosis in patients who had had elevated troponin I concentrations. Concl usions: In laboratory adverse event predict elevated postprocedure troponin I c oncentrations which are associated with myocardial injury. These elevations, in turn, predict poorer medium term clinical outcomes.

已有报道指出，急性缺血性卒中患者的肌钙蛋白水平升高。在此项前瞻性研究中，检查244例无明显缺血性心脏病的急性缺血性卒中患者中肌钙蛋白升高的发生率及其特征。在入院的最初5d，每日检测肌钙蛋白T（TnT）和肌酸激酶-MB（ck-MB）浓度并进行12导联心电图检查。对TnT水平≥0．10μg／L的患者进行心肌灌注显影检查，并与TnT未升高的对照者进行比较。患者平均随访19±7个月，以全因死亡为临床终点。分别在10％和9％的患者中检出TnT（〉0．03μg／L）和ck—MB水平（≥10μg／L）升高。TnT升高的患者中心力衰竭和（或）肾衰竭的发生率更高。与对照者相比，TnT水平≥0．10μg／L患者的静息心肌灌注显影检查中灌注异常并不更常见或更显著。
