The paper provides a critical comparison between mesophilic and thermophilic anaerobic treatment of pta wastewater through diagnosis of a case study. Aspects covered are bioavailability, biodegradability, microbial population, thermodynamics, kinetics involved and bio-reactor design for pta wastewater treatment. The results of the case study suggests that one- stage thermophilic anaerobic reactor coupled with coagulation-flocculation pre-treatment unit and an aerobic post treatment unit could be techno-economically viable for pta wastewater treatment to ensure that the final effluent quality conforms to the international standard. The in-formation emanated from this study could be useful and thought provoking to the professionals and academia in the area of pta wastewater treatment and can serve as impetus toward the development of research lines in similar problems like the treatment of other petrochemical wastewater such as phenol-con- taining wastewater, benzene/benzoic acid-con- taining wastewater or wastewater from other similar industrial settings.

目的TRIO基因位于染色体5p扩增区、编码1种在细胞周期调节中起主导作用的蛋白,本研究旨在了解TRIO的扩增和表达是否与膀胱肿瘤细胞的快速增殖有关。方法Ki67标记染色(Ki67LI)、荧光原位杂交(FISH)和定量PCR法(LightCyclerTMPCR)被用于研究。结果TRIO基因扩增与膀胱肿瘤细胞的快速生长相关(Ppta)(9例/499例),而在膀胱癌(pT1-4)高达12.8%(62例/485例)。定量PCR法进一步证实TRIO在显示5p扩增的膀胱癌组织高表达。结论TRIO扩增与膀胱肿瘤细胞的快速增殖有关,TRIO扩增和高表达可能在膀胱癌的发展过程中发挥重要作用。

Rice is largely self-fertilized and accordingly a field population of rice is completely composed of near homozygotes. Due to the emergence of off-types, homozygosity will be affected. With the time, this will cause the reduction of genetic purity in some rice varieties. One of the reasons has been suspected to be the high out-crossing frequencies of such varieties. Studies were conducted at the Rice Research and Development Institute, Batalagoda, Sri Lanka to estimate the out-crossing rate of Bg 379-2, a variety having the problem of maintaining genetic purity. Bg 379-2 was allowed to out-cross with Bg 450 and the number of out- crossed plants were counted using dominant morphological markers such as short-round grain and purple culm of pollen donor. A molecular confirmation of out-crossing was also performed using sequence tagged site （STS） molecular marker pta248. The variety Bg 379-2 showed a potential out-crossing rate of 3.41% and an average out-crossing rate of 1.29% using dominant morphological markers. Polymorphism was cleady detected between parents and out-crossed plants as well as selfed plants of Bg 379-2 using their banding patterns. A similar study can be performed to determine the out-crossing rates of other varieties which show high percentage of off-types in the population for the better understanding of the breeding behavior of the varieties.

目的评估经皮再通术的长期效果,确定在大样本的Budd-Chiari（BCS）综合征中国病人中对通畅性和生存的预测因素。材料与方法机构伦理委员会批准了该项回顾性研究。所有病人在参加本研究前均签订知情同意书。在1999年7月—2010年8月,177例连续原发BCS中国病人接收了经皮再通术,随访至死亡或至最后一次临床评估。记录再通治疗策略和并发症。累积的通畅性和生存率通过Kaplan-Meier曲线进行分析。使用Cox回归分析模型来计算通畅和生存的独立预测因素。结果 177例病人中有168例（95%）接受经皮再通术获得成功。168例病人中有51例（30%）单独接收了经皮腔内血管成形术（pta）,117例病人接收了pta和支架植入术。168例病人中有7例出现了与该治疗有关的并发症。1、5、10年累积的初始通畅率分别为95%、77%、58%。闭塞的独立预测因素为白细胞计数的增加和单独使用pta。1、5、10年累积的二次通畅率分别为97%、90%、86%。在中位值30个月的随访中有22例病人死亡（范围0.25;37个月）。1、5、10年累积的生存率分别为96%、83%、73%。与生存有关的独立预测因素为静脉曲张性出血、碱性磷酸酶及血尿素氮水平升高、再闭塞。结论在有BCS的大部分中国病人中经皮再通术可以达到很好的长期通畅性和生存效果。pta联合支架植入可以减少再次闭塞的发生率和与其相关的死亡率。
