Thoracic aortic aneurysm is associated with increased morbidity and mortality in pregnancy. Various pregnancy-related physiologic changes appear to make pregnancy a high risk situation for rupture of an arterial aneurysm. The hemodynamic and endocrine changes of pregnancy appear to be the cause of arterial alterations which may lead to new aneurysm formation and/or weakening of preexisting aneurysms. Successful term pregnancy and cesarean delivery of a patient with aortic aneurysm is presented.

Background/Aims: In recent years, intravenous catheters have been used in the hospitalized patients requiring fluids and medications, monitoring of the central venous pressure, and receiving the hyperalimentation. In spite of their usefulness in the management of the critically ill patients, the complications related to the intravenous catheters such as thrombosis, phlebitis, and sepsis have been well known. However, the actual incidence and bacterial pattern have not been well studied. This study was to investigate the difference in clinical way between colonized catheters and catheter-related bloodstream infections. Methods: From January 2004 to January 2005, 89 patients had done central venous catheters(CVC), receiving total parenteral nutrition(TPN) 51 and CVC for venous access 56 patients were included in this study. The patients ranged in age from 49 to 80 years, We evaluated 89 central venous catheterization patients were analyzed for blood culture, fever and catheter tip culture to identify the relationship between infectious complication and various clinical characteristics. Results: TPN formulas, indications of CVC, underlying diseases were associated with highter rates of positivity of blood cultures (P<0.05). Duration of CVC was related to the fever (P<0.05). No significant correlation was observed between duration of TPN and fever or blood cultures. Conclusions: TPN formulas and the duration of catheter dwelling time are associated with bacteremia and fever respectively. But this is more likely to be secondary to underlying diseases. Further study needs to be conducted in order to establish whether infectious complications are more related to TPN via CVC itself.

Tocopherols (α-, β-, γ- and δ-tocopherols) represent a group of lipophilic antioxidants which are synthesized only by photosynthetic organisms. It is widely believed that protection of pigments and proteins of photosynthetic system and polyunsaturated fatty acids from oxidative damage caused by reactive oxygen species (ROS) is the main function of tocopherols. In the present study, NtTC, which encodes a tobacco tocopherol cyclase ortholog, was cloned and characterized. Compared with control plants, NtTC transgenic rice showed higher tolerance to drought stress, and total tocopherol content increased by 52 % in leaf. Additionally, total antioxitant activity of NtTC transgenic lines was increased significantly by 19%. These results demonstrate that over-expressing NtTC could improve the tolerance to abiotic stress in rice, and tocopherols play a crucial role in the protection of oxidative stress.
