可口可乐收购汇源案的反垄断法思考

自《反垄断法》实施以来,第一个也是迄今为止唯一一个被商务部禁止的集中案件——可口可乐收购汇源案,引发了广泛的争议。从反垄断法的角度来看,需要在相关市场及市场控制力、市场进入和效率抗辩等几个方面展开具体分析。通过分析发现,集中并不会导致强有力的市场控制,果汁饮料市场的市场进入情况也相对容易。集中还可能提高效率,尽管要证明效率为集中所特有并必然给消费者或社会公众带来福利仍然较为困难。商务部的禁止决定存在＂合法但不合理＂的嫌疑,实则反映了我国公平有效的竞争制度的缺失。要杜绝类似的合理性怀疑,还需搭建更为基础的竞争制度平台。     

论中国企业联营的经营者集中控制

企业联营可能带来能够促进效率的经济活动的整合,又可能损害竞争,因此一直是反垄断法适用的一个重要议题。企业联营的反垄断规制主要涉及到经营者集中的反垄断审查和垄断协议的规制,欧盟和美国两大法域各自形成了一套规制模式。在中国,《反垄断法》没有对企业联营的经营者集中控制做出专门的规定,企业联营应当通过何种方式规制仍存在不确定性。实践中应当立足于现行规定的解释,结合成熟法域的反垄断法经验,从适用模式、规制对象和竞争效果评估三个层面缕析,建构企业联营经营者集中法律规制的理性模式。     

论道路交通事故与驾驶员血中酒精含量关系

目的探讨道路交通事故与饮酒驾车血中酒精含量关系及其法医学意义,为预防、控制道路交通事故提供重要依据。方法对2005份道路交通事故肇事驾驶员血酒精鉴定资料进行系统分析性研究。结果饮酒驾车以男性为主,女性饮酒驾车出现醉酒驾车的比例与男性无差别。市区驾驶员醉酒驾车高于郊区。驾驶员BAC<20mg/100mL肇事导致死亡的比例高于饮酒驾车肇事组(BAC20￣79mg/100ML),而BAC≥80mg/100mL则低于饮酒驾车肇事组。结论应降低饮酒驾车和醉酒驾车BAC标准,以利于减少交通事故肇事死亡率。     

双眼交替微量取样检测兔玻璃体液钾镁离子浓度推测死亡时间

目的研究死后眼玻璃体液钾镁离子浓度变化及其与死亡时间的关系。方法取健康家兔处死,死后不同时间于双眼玻璃体液交替微量取样,采用全自动生化分析仪检测样本中[K+]、[Mg2+],对所得数据进行统计学处理。结果死后12~120h,家兔玻璃体液中[K+]由11.01mmol/L上升至32.97mmol/L,[Mg2+]1.12mmol/L上升至2.22mmol/L,两种离子浓度与PMI进行回归分析自变量为[K+]的二次多项式回归方程为y=0.1756x2-3.3188x+29.804(R2=0.9868);自变量为[Mg2+]的二次多项式回归方程为y=-46.916x2+248.01x-213.81(R2=0.9340);自变量为[K+]和[Mg2+]的二次多项式回归方程为y=-17.55-4.82[K+]+0.20[K+]2+75.77[Mg2+]-19.47[Mg2+](R2=0.9881)。用[K+]的方程推测PMI,当[K+]<26.0mmol/L(PMI<60h)时,平均偏离时间为2.7~9.4h,当[K+]>28mmol/L(PMI>72h)时,平均偏离时间>15h;用[Mg2+]的方程推测PMI,平均偏离时间几乎均在10h以上;用二元方程推测PMI,平均偏离时间较前两者小。结论死后眼玻璃体液[K+]、[Mg2+]随时间延长而升高,且浓度变化与时间呈强相关性。但从实际运用角度考虑,R2<0.98,或平均预测偏离时间过大的回归方程,不宜用于PMI推测;应用多指标建立多元回归方程是提高推测PMI准确性的可行方法。     

Parent and Metabolite Opioid Drug Concentrations in Unintentional Deaths Involving Opioid and Benzodiazepine Combinations,,

Effects of benzodiazepines on postmortem opioid parent and parent/metabolite blood concentration ratios were determined for fentanyl‐, hydrocodone‐, methadone‐, or oxycodone‐related accidental deaths. These opioids are partially metabolized by the CYP3A4 enzyme system, which is also affected by diazepam and alprazolam. Opioid/metabolite combinations examined were as follows: fentanyl/norfentanyl, hydrocodone/dihydrocodeine, methadone/EDDP, and oxycodone/oxymorphone. Parent opioid concentrations were analyzed for 877 deaths. Parent/metabolite concentration ratios were analyzed for 349 deaths, excluding cases with co‐intoxicants present known to interfere with opioid elimination. Alprazolam in combination with diazepam significantly decreased median hydrocodone concentrations by 48% (p = 0.01) compared to hydrocodone alone. The methadone parent/metabolite concentration ratio was reduced by 35% in the presence of diazepam compared to methadone alone (p = 0.03). Benzodiazepines did not statistically significantly affect fentanyl or oxycodone concentrations. Possible factors affecting opioid concentrations and possible toxicity development, including any differential effects on specific opioids, should continue to be explored.     

企业合并行为的竞争法分析

对企业合并进行控制是竞争法的基本内容,而其中最核心的问题,是评价企业合并行为所依据的实体标准。基本内容包括对合并行为的反竞争影响,及其产生的积极效果。由于企业合并主要是通过改变市场结构而影响竞争,因而在对其进行分析时,一般首先分析合并行为对所在市场集中度产生的影响,这主要通过赫芬达尔指数来反映,对于发生在指数较低的市场上,或发生在集中度较高的市场上,但并未导致指数大幅度提高的企业合并行为,认定其不会产生严重的反竞争效果,可以批准。其他的合并行为则要由竞争主管机关进一步分析,主要考察该行为的反竞争效果,包括单边效果与协调效果;然后再考察存在哪些抵消因素。经过比较后,如果积极效果大于消极效果,则予以批准。     

中草药对乳牛乳腺炎主要病原菌的体外抗菌活性试验

采用试管二倍稀释法,测定了金银花、连翘和蒲公英等12种中草药及其复方制剂对乳牛乳腺炎主要病原菌(大肠埃希氏菌、金黄色葡萄球菌、无乳链球菌和停乳链球菌)的体外抗菌活性(MIC和MBC)。试验结果表明,金银花、连翘和蒲公英及其复方制剂对这4种病原菌均具有较强的体外抗菌活性。     

Death by potassium chloride intravenous injection: evaluation of analytical detectability

Potassium chloride intravenous injection is used in suicide attempts and lethal procedures for state-sanctioned punishment. Owing to its relatively high concentrations in hemolyzed blood (25-80 mM) compared to serum (about 4 mM), it is difficult to conclude potassium poisoning by postmortem analysis of biologic samples. A 41-year-man was found dead with an injection sign on his foot and a syringe close to the corpse. No particular signs were noted during the autopsy. Blood, bile, and urine were submitted to xenobiotic screening procedures used in the laboratory. Syringe content was found positive to potassium ions. Blood potassium concentration was determined by ion-selective electrode measurement (range 3.0-150 mM). Blood was found positive for diazepam at therapeutic level. Potassium concentration was 160.0 (cardiac) and 87.3 mM (femoral blood). Our results show that potassium concentration was significantly higher in heart blood in a suicide case. Hence, the general issue of considering potassium poisoning hardly demonstrable by toxicology needs to be questioned and thoroughly studied.
