Objective To investigate the risk factors of hyperthermia in early period of an acute cerebral infarction.Methods 299 patients admitted to hospital from January 2003 to December 2004 with a diagnosis of cerebral infartion by CT or MRI,were retrospectively studied.The risks of hyperthermia in the early period for stroke,such as admission conscious level,bulbar palsy,emphysema,atrial fibrillation,multi-cerebral infarction,diabetes mellitus and chronic heart failure were analyzed,Logistic regression analysis was used to determine the factors that were associated with hyperthermia in the early period of stroke.Results 71 patients had fever in early period of an acute cerebral infarction(23.7%).The most common infection was pneumonia(18.4%).The analysis showed that the admission conscious level and atrial fibrillation were the risks of early hyperthermia of an acute cerebral infarction.Conclusion Admission conscious level(subconscious or unconscious/coma) and atrial fibrillation and chronic heart failure are independent risk factors for development of early hyperthermia for acute stroke.

Nano-metallic materials are playing an important role in the application of medicine, catalysis, antibacterial and anti-toxin due to their obvious advantages, including nanocrystalline strengthening effect, high photo-absorptivity, high surface energy and single magnetic region performance. In recent years, with the increasing consumption of global petrochemical resources and the aggravation of environmental pollution, nanomaterials based on bio-based molecules have aroused great concern. Bio-based molecules refer to small molecules and macromolecules directly or indirectly derived from biomass. They usually have good biocompatibility, low toxicity, degradability, wide source and low price. Besides, most bio-based molecules have unique physical, chemical properties and physiological activity, such as optical activity, acid/alkali amphoteric property, hydrophilic property and easy coordination with metal ions. Thus, the corresponding nano-materials based on bio-based molecules also have unique functions, such as anti-inflammatory, anti-cancer, anti-oxidation, antiviral fall blood sugar and blood fat etc. In this paper, we give a comprehensive overview of the preparation and application of nano-metallic materials based on bio-based molecules in recent years.
