树立正确的执法理念 提高执法水平

当前公安执法工作在打击犯罪过程中取得了显著成效,但同时还存在着一些重实体、轻程序,重尽快破案、轻依法办案等突出问题,纠其原因,除了制度、法规缺乏完善的客观原因外,主要是执法思想不端正。因此,树立正确的执法理念,对于依法办案,提高执法水平具有重要意义。     

分众化时代电视节目主持人个性化浅议

主持人的个性就是个人综合素质和人格魅力的浓缩,它与节目在受众中的传播效果息息相关。本文着重从主持人与节目价值取向、角色回归、专业水准、人格化传播等方面阐释主持人只有体现个性化,才能有持久的生命力。     

用乙醇和正丁醇判断豚鼠溺死时间的实验探索

本文以豚鼠为实验动物，溺死后浸泡于水温为２０℃的水缸小。运用气相色谱法测定其溺死后不同浸泡时间在心、肺、肝小＃在的乙醇和正了醇含量。实验结果表明在溺死后８天内，样本中乙醇和正了醇量随浸泡时间的延长而增加，且呈高度的直线相关。其血、肺、矸中乙醇量与溺死时间的回归方程依次为ｙ１＝－１６．８２＋１２．９５Ｘ，ｙ２＝－５８．５３＋１９．２３Ｘ，ｙ３＝－３１．９１＋４７．２９Ｘ。血、肺、肝小正丁醇量与溺死时间的回归方程依次为ｙ４＝－１０．１３＋５．８６ｘ，ｙ５＝－２９．４５＋１６．１７ｘ，ｙ６＝３．７５＋１４．３１ｘ。综合分析溺死后血、肺、肝小乙醇和正丁醇，有可能作为判断溺死时间的新指标。     

违反法律、行政法规强制性规定的合同的法律效力辨析——对《合同法》第52条第5款的司法应用的解读

在司法实践中,由于不同的理解,对违反法律、行政法规强制性规定的合同法律效力的认定,在理论和司法实践中,出现了较大的偏差,因此有必要对此作进一步的澄清。本文试分析德国和台湾地区在此方面的理论和实际操作,结合我国国内立法现状,指出我国司法审判在适用该规定时,应充分考虑“强制性规定”所保护的权益与合同本身所涉权益平衡关系,并根据权益平衡结果区别确定合同的法律效力。     

Introduction of a standardized "paternity index" for the statistical evaluation of blood group findings in paternity testing

The introduction of a standardized paternity index (PI) for the statistical evaluation of blood group findings in cases of disputed paternity is proposed and explained. By using the PI $\text{X}\text{Y}$ as parameter, it is not necessary to give the information of the probability of paternity in percent. The PI includes the full information of the blood group findings. In addition to that, by using the suggested standardization based on the probabilities of error according to Schulte Mönting and Walter the test volume is also taken into account. The interpretation of the mathematical result is given by verbal predicates, the limitations of which are orientated by the verbal predicates for the probabilities of error according to Schulte Mönting and Walter, published by us elsewhere. Besides the essential fact that the test volume is taken into account, the most important advantage of this procedure is that the mathematical result is involved in the court decision only by the PI (which is free of any valuation) and its verbal predicate and not by sometimes relatively high percentages, which may be misunderstood by laymen.     

抗人N单克隆抗体的理化特性研究及其初步应用

本文报告理化因素对抗人N单克隆抗体(ON_1D_3)活性的影响。P~H及反应温度对ON_1D_3单克隆抗体与人红细胞的血凝反应有显著的影响。较适宜的实验条件为P~H7.0,温度30℃。在此条件下对155例新鲜血液及60例陈旧血痕样品进行MN分型。结果与用市售兔抗N血清测定的结果完全一致,证明在上述条件下,ON_1D_3单克隆抗体可用于临床常规血液分型及法医学上对陈旧血痕MN血型的测定。     

丙酸钠和丙酮酸钠对体外培养牛肝细胞内丙酮酸羟化酶基因mRNA水平的影响

在成功构建牛肝细胞培养模型和PC基因DNA竞争模板的基础上,采用竞争RT-PCR方法检测了丙酸钠和丙酮酸钠对体外培养新生牛单层肝细胞PC基因mRNA丰度的影响。结果,随着丙酸钠浓度的升高,PC基因mRNA水平呈上升趋势,PC基因mRNA对丙酸钠的耐受范围较广;随着丙酮酸钠浓度的升高PC基因mRNA水平呈先上升后下降的趋势。结果表明,肝细胞内PC基因mRNA的表达水平受丙酮酸钠浓度的调控,在一定范围内丙酮酸钠对PC基因mRNA的转录具有促进作用,而浓度过高时则起抑制作用。     

A multivariate investigation of dating aggression

This study investigated the following variables for their unique and combined contributions to dating aggression: exposure to aggression in the family of origin (witnessing interparental aggression or being the victim of aggressive parenting); attitudes justifying dating aggression (when humiliated or in selfdefense); child-to-parent aggression; child sexual abuse; violent sexual victimization; alcohol use; and socioeconomic status. One hundred and eleven male and 179 female undergraduates reported on their own aggressive behaviors directed toward dating partners. Together, the predictor variables accounted for 41% of the variance in male-to-female aggression but only 16% of the female-to-male aggression. Humiliation, as a justification for dating aggression, contributes to the prediction of both males' and females' dating aggression, while self-defense, although a highly endorsed condition for justifying dating aggression, does not predict actual aggressive behavior. Exposure to interparental aggression plus the product between exposure and humiliation contribute to the prediction of males' dating aggression but exposure does not play a role in females' dating aggression. Violent sexual victimization contributes unique variance to both males' and females' dating aggression. The present data highlight the importance of examining specific circumstances under which males and females justify dating aggression and how such attitudes condoning aggression affect actual behaviors.     

针灸对胃粘膜损伤的保护作用及其与NO的关系

建立７０％乙醇灌胃致大鼠胃粘膜急性损伤模型，以胃粘膜血流量，胃跨壁电位差，胃粘膜损伤指数为指标，并测定血液中，胃粘膜中一氧化氮含量，研究针灸对胃粘膜损伤的保护作用及其与ＮＯ的关系。结果显示：针灸对胃粘膜损伤具有保护作用。ＮＯ的前体Ｌ－精氨酸和ＮＯ的代价供体硝普钠对胃粘膜也有保护作用，而ＮＯ合成酶的抑制剂Ｎ－亚硝基左旋精氨酸未显示出胃粘膜有保护作用。     

月经血鉴定与基质金属蛋白酶-11

月经血鉴定是法医血痕检验的内容之一。本文就月经血鉴定的几种经典方法进行回顾,并分析其应用局限性。基质金属蛋白酶-11是一种能降解细胞外基质的水解蛋白酶,有研究提示基质金属蛋白酶-11以其在月经血中表达的特异性和检测方法的灵敏性有可能成为对月经血鉴定的新一代标志物。本文对基质金属蛋白酶-11的结构、功能、在月经血鉴定中的应用及展望进行综述。
