RESUMO
Information-based teaching was applied in the experimental teaching of nuclear protection medicine based on its own features.The teaching content was sent to students as micro-video via an information platform before class for preview;during the class,the teaching was performed in the form of lectures by students and experiments in groups;after class,students were required to submit reports of experimental improvement or innovative experimental design.A comprehensive assessment was performed for preview,classroom operation,question answering in class,and experimental reports.The results of teaching practice showed that this teaching mode can effectively stimulate the students' interests in learning,enhance their research and innovation abilities,and improve the experimental teaching effect of nuclear protection medicine.
RESUMO
This work was designed to study a novel dry powder inhalation (DPI) carrier for drug loading and release of tiotropium bromide (asthma medicine). The synthesized lactose drug-carrier with a flower shape was crystalline. The carrier with a micro-meso-macroporous structure had advantages of high pore surface area, high capacity of drug loading and fast release of drug. In the study of loading tiotropium bromide, the drug was distributed at the core of carrier using the solution-based method, while the morphology was changed a little and the amount of loaded drug was 5% (w/w). Using the crystallization-based method, the drug was distributed at the shell of carrier, while the morphology was changed a lot and the amount of loaded drug was 49% (w/w). In addition, with the impact of carrier structure, the drug release rate was increased first and then decreased thereafter using the solution-based method, while the drug release rate was decreased first and then increased thereafter using the crystallization-based method. Thus, the lactose microparticles can be used as a novel drug carrier for dry powder inhalation.
RESUMO
【Objective】To observe the therapeutic effect of traditional Chinese comprehensive therapy for the treatment of lumbar disc herniation.【Methods】Forty-one lumbar disc herniation patients received oral use of herbal medicine,external application of herbal medicine,fumigation and steaming with herbal medicine as well as pelvis traction.Fifteen days constituted one treatment course.【Results】After treatment,25 were cured,13 effective,3 ineffective and the total effective rate was 92.68%.【Conclusion】Comprehensive therapy including oral use of herbal medicine,external application of herbal medicine,fumigation and steaming with herbal medicine as well as pelvis traction has a good effect on relieving symptoms.
RESUMO
Objective:To investigate the relationship between blood lead and blood microelements levels and attention-deficit/ hyperactivity disorder.Methods:To compare the children of ADHD and control groups,levels of blood lead were analysised by anodic stripping voltammetry,and blood microelement Levels were detected by atomic absorption spectrophotometry.Results: Blood lead levels were significantly higher in ADHD than that in control group (P
