Gastrointestinal duplication is an uncommon congenital abnormality in two-thirds of cases manifesting before the age of 2 years. Ileal duplication is common while colonic duplication, either cystic or tubular, is a rather unusual clinical entity that remains asymptomatic and undiagnosed in most cases. Mostly occurring in pediatric patients,colonic duplication is encountered in adults only in a few cases. This study reports two cases of colonic duplication in adults. Both cases presented with rectal bleeding on admission. The study was focused on clinical, imaging,histological, and therapeutical aspects of the presenting cases. Gastrografin enema established the diagnosis in both cases. The cystic structure and the adjacent part of the colon were excised en-block. The study implies that colonic duplication, though uncommon, should be included in the differential diagnosis of rectal bleeding.

The photoelectrochemical behaviour of the multilayer semiconductive electrode(GaAs/AlxGa1-xAs)with the structure of N+NP and N+NPP was studied in Na2SO4 solution. Compared with single kind semiconductor electrode, the commposite one has broader photoresponse spectral region and larger open-circuit photovoltage,consequently gives higher solar energy conversion efficiency.

The main function of neurons is information transmission in the form of action *** fulfill this duty,neurons are connected functionally with each other via synapses,the microscopic structures where specialized molecular machinery is strategically placed to release and receive neurotransmitters and to generate and extinguish calcium(Ca^(2+))*** synaptic molecular components are highly dynamic and they influence each other to confer structural and functional adaptability(plasticity)to neuronal communication(Biederer et al.,2017).

Intrahepatic cholangiocarcinomas (ICC) are neoplasms that originate from cholangiocytes and can occur at any level of the biliary tree. Surgical resection is the current therapy of choice for this highly aggressive cancer. However, the 5-year survival still is poor, with high recurrence rates. Due to the intrahepatic growth a signifi cant proportion of patients present with advanced disease and are not candidates for curative surgery or transplantation. The existing palliative options are of limited benefit and there is a great necessity for novel therapeutic options. In this article we review the role of the phosphoinositide 3-kinase(PI3K)/ AKT and extracellular regulated kinase (ERK) signaling pathways in ICC and present new data on the prognostic value of these protein kinases. Finally, we discuss future upcoming therapeutic options based on targeting these signaling pathways.

马修·阿诺德是维多利亚时期著名的文学批评家和社会批评家。他认为人文教育和文化熏陶对当时英国日渐兴起的民主格外重要。本文认为,阿诺德其时其地对其国人的忠告对当下的中国仍有重要意义。1867年通过的《第二改革法案》赋予(男性)工人阶级选举权,其时的英国已经成为一个富强的国家,但在阿诺德看来,英国如无远虑,不足以在未来站稳脚跟。阿诺德坚信,无论哪个国家,终将是那部分有奉献精神的、无私的少数人,即那部分“正直的少数者”把国家从庸俗和混乱的状态中拯救出来,他们的存在意义要远远大于那些疲于奔命的芸芸众生。或许,当下的中国有必要呼唤阿诺德力荐的“少数者”,致力于激发和提升人们高雅的心智和品味。

The intramolecular photochedcal interaction of a series of bis-coumarinyl compounds with various alkyl chain lengths (An) has been studied in/without the presence of β-cyclodextrin (β-CD) by fluorescence spectroscopy. The results show that both photedimerization andexcimer formation can occur in the respective favourable microenvironments.
