Cellular senescence determines endothelial cell damage induced by uremia

Renal dysfunction is closely associated with endothelial damage leading to cardiovascular disease. However, the extent to which endothelial damage induced by uremia is modulated by aging is poorly known. Aging can render endothelial cells more susceptible to apoptosis through an oxidative stress-dependent pathway. We examined whether senescence-associated to oxidative stress determines the injury induced by the uremia in endothelial cells.     

Alcoholics Anonymous

This article explores some of the philosophical roots of Alcoholics Anonymous. Parallels between AA, existentialism and phenomenology are outlined. The success of AA is related to its ability to place the alcoholic's suffering within a meaningful paradigm and to require the alcoholic to accept responsibility and limitations while breaking the pattern of isolation and alienation.

Identification of the potential biomarkers for the metastasis of rectal adenocarcinoma

Rectal cancer is a common malignant tumor of the digestive tract, with a high incidence and high mortality. This study aimed to identify the potential biomarkers and therapeutic targets for rectal adenocarcinoma (RAC) metastasis. The expression profiling of RAC patients with metastasis and RAC patients without metastasis was downloaded from The Cancer Genome Atlas (TCGA) database. The datasets were used to identify the genes associated with RAC metastasis. Fifty up‐regulated genes and seventeen down‐regulated genes were identified in the primary tumor loci of RAC metastasis compared with non‐metastasis. Sixty‐seven dysregulated gens were conducted to construct the protein–protein network, and CCND3 was the hub protein. The dysregulated genes were significantly enriched in pancreatic secretion, cell adhesion molecules pathways, response to vitamin D of biological process, and retinoid binding of molecular function. Quantitative real‐time polymerase chain reaction results demonstrated that CCND3, AQP3, PEG10, and RAB27B had the up‐regulated tendency in RAC metastasis; ADCY1 had the down‐regulated tendency in RAC metastasis. CCND3, AQP3, PEG10, RAB27B, and ADCY1 might play essential roles in the metastasis process of RAC through pancreatic secretion and cell adhesion molecules pathways. The five genes could be potential diagnosis biomarkers or therapeutic targets for RAC metastasis.     

Making a working clinical diagnosis of HIV infection in infants in Zimbabwe

Objectives Clinical algorithms can be helpful in decisions about treatment and feeding options in infancy, but have had limited exposure to real data. This analysis uses data from a large clinical trial to test such algorithms, and thereby develop a successor which performs usefully in poor countries with high HIV‐prevalence. Methods The ZVITAMBO trial followed 14 110 mother‐baby pairs through infancy. 32% of mothers were HIV‐positive. Infants were HIV tested regularly using DNA PCR. Clinical signs were evaluated in terms of identifying HIV‐infection at 6 weeks, 6 and 12 months, using Zimbabwean, South African, and WHO generic adaptations of the WHO integrated management of childhood illness HIV algorithm. A modification, in which HIV‐exposed infants are first divided into being at least or less than median weight‐for‐age, was derived and evaluated. Results At 6 weeks 65% of all infected babies are less than median weight‐for‐age. Adding at least two clinical signs reduces sensitivity to 20% but those identified are 1.5 (95% CI 1.1–2.1) times more likely to die by 6 months than other infected infants. At 6 months, 86% of uninfected babies of HIV‐infected mothers can be identified by selecting those whose weight is greater than median or, if less than median, who exhibit <2 clinical signs. Conclusions In poor settings a simple clinical algorithm can identify children with probable HIV infection, especially those at risk of early death, who can then be referred for further testing and care, including highly active antiretroviral therapy. Most infants who are HIV‐uninfected can be identified at 6 months and provided with support to maintain infection‐free survival, including focussed infant‐feeding counselling.

纤维支气管镜引导双腔气管导管插管和可视双腔气管导管插管的对比研究

目的比较纤维支气管镜引导普通双腔气管导管插管和可视双腔气管导管插管用于开胸手术单肺通气麻醉的临床效果。方法选择需行开胸手术的患者60例,随机均分为两组。分别使用纤维支气管镜引导普通双腔气管导管插管和可视双腔气管导管插管。比较两组双腔气管导管定位时间及观察插管应激的血流动力学反应。结果可视双腔气管导管插管组气管导管定位时间比纤维支气管镜引导普通双腔气管导管插管组短,定位及术中管理便捷;可视双腔气管导管插管组插管引起的血流动力学反应与纤维支气管镜引导普通双腔气管导管插管组也没有差异。结论可视双腔气管导管定位时间短,定位准确,易于术中管理。但是仅有左侧双腔一种类型,应用范围存在一定局限性。
