In order to analyse plasma norepinephrine (NE) and neuropeptide Y like immunoreactivity(NPY LI)in relation to cardiac function,41 patients with congestive heart failure(CHF) and 10 healthy volunteers were *** samples were obtained from the arterial and coronary *** was measured by high performance liquid chromatography and NPY LI by *** data were derived by right heart *** fraction(EF) was measured by radionuclide angiography ,cine angiography or M mode echocardiograms. Groups of CHF patients with high EF (3..3. 1.3. ) and low EF (17.7±1.1%) were compared with the normal *** were pronounced and significant increases in circulating arterial NPY LI and NA in both the high and low EF groups compared to the *** CHF patients,myocardial NPY LI release tended to be increased compared with normal subjects,however,this was not statistically significant(P=n.s.).While normal subjects showed myocardial NE uptake,patients with CHF demonstrated significant and progressive myocardial NE *** as well as coronary sinus NPY LI correlated significantly with plasma NE concentrations from the respective *** NE concentrations in the artery and coronary sinus were negatively correlated with EF and cardiac index while no such relationships were found for NPY *** results suggest that NPY LI is released together with NE in moderate to severe forms of ***,only plasma NE correlates with EF and ***,plasma NE concentration measurements seem to be the more sensitive index of cardiac dysfunction in CHF than NPY LI.

＜正＞Objective:To investigate whether shear stress would regulate the expression of Bcl-2,Bax and Caspase-3.via the PI3./Akt pathway in arterioles of aged ***:Second-order mesenteric arterioles of young（6 months） and aged（24 months） male SD rats were selectively ligated to elevate blood flow in first-order arterioles as high blood flow（HF）.A 3.d to 5th first-order arteriole proximal to the HF arteriole was selected as the normal blood flow （NF）.Three weeks after surgery,the arterioles were isolated and measured by vascular perfusion *** changes of arteriolar wall elasticity and the wall thickness of the first-order arterioles with HF and NF were *** expression of Akt,p-Akt,Bcl-2,Bax and Caspase-3.in NF and HF of young and aged rats were determined by western ***:（1） Compared with young rats,the content of arteriolar collagen fiber was increased,whereas the elasticity of arterioles was reduced in aged *** increased intravascular fluid shear stress,the elasticity of arterioles was increased and the function of arterioles was improved,however,there was no significant change in arteriolar morphology.（2） Western blot analysis showed that shear stress increased expression of p-Akt and Bcl-2,while decreased expression of Bax and Caspase-3.in NF arterioles of both *** aged rats,shear stress regulated p-Akt,Bcl-2 and Caspase-3.production in HF arterioles to a level similar to NF arterioles of young ***:Shear stress increased phosphorylated Akt production and played a key role in the regulation of Bcl-2,Bax and *** it can increase the flexibility and state of rat *** results suggest that shear stress acts as an efficient stimulus to improve function of mesenteric arterioles in aged rats via the PI3./Akt pathway.

Cu经过等径角挤压（ECAP）变形后,屈服强度达到了约400 MPa,然而加工硬化能力不足导致其在小应变阶段就开始颈缩（≤2%）。研究发现,可以通过部分再结晶退火调控变形Cu的室温准静态拉伸性能。在275℃退火10 min后,其准静态拉伸强度和塑性得到了良好的匹配：在保持屈服强度为3.0 MPa的前提下,均匀伸长率达5%。

在将中亚以东南，即东亚、南亚、东南亚家牛划分为“蒙古利亚”、“中间”、“南岛”三大集团的既有研究结论的基础上，根据群体遗传学原理和模糊集合理论，论证了这一地域家牛血统的三个判别式；以９个已知群体３个基因座１８个等位基因频率的实例对这些判别式进行了验证。根据验证结果，确认了其中最理想的判别式；并检查以该式判别两个未知群体血统的结果是否符合已知的畜牧学逻辑。在该式的论证中，从遗传学、数学的角度，将１—线性遗传模糊度定义为“遗传贴近度”，即：（Ｉ～，Ｘ～）＝１－ξ（Ｉ～，Ｘ～）＝１－２Ｋ∑ｋｊ＝１｜μＩ～（ｐｊ）－μｘ～（ｐｊ）｜其中，μＩ～（ｐｊ）为第ｊ等位基因对第ｉ已知集团的隶属函数，μＸ～（ｐｊ）为第ｊ等位基因对受判别的Ｘ群体的隶属函数，亦即该基因分别在第ｉ集团和Ｘ群体中的频率；Ｋ为所依据的等位基因数；ξ（Ｉ～，Ｘ～）为线性遗传模糊度。该式也适用于其它遗传标记。结果肯定，群体与已知集团之间的遗传贴近度是血统判别的可靠根据。
