BACKGROUND: Iron metabolism disorder has been proved to be a key factor of Parkinson's disease, but research on brain iron metabolism is still immature, and the role of glial cells in the brain iron metabolism remains unclear. Many studies have pointed that microglia plays an important role in the pathogenesis of Parkinson's disease, which closely related to iron.OBJECTIVE: To further explore the relationship between microglia and neurons in iron metabolism based on our previous study, and to clarify the role of microglia in iron-induced selective damaged dopaminergic neurons of Parkinson's disease.METHODS: This was an in vitro cellular experiment, which was finished in the Medical College of Qingdao University, Shandong Province, China. The effects of conditioned medium of microglia on the survival rate of mesencephalic neurons and iron metabolism were observed by changing the iron levels in microglia.Lipopolysaccharide was used to activate different iron-loaded microglia, and then the effects of conditioned medium on the survival rate of mesencephalic neurons and iron metabolism were determined. The effects of different iron levels in microglia on microglia and inflammatory factors and lactoferrin released from the activated microglia were detected by siRNA and ELISA. The effects of these inflammatory factors and lactoferrin on the survival of mesencephalic neurons and iron metabolism were observed. The iron levels in mesencephalic neurons were changed, and then added into the above conditioned medium to observe the survival of neurons and iron metabolism. This experimental protocol was approved by the Hospital Ethics Committee (No. 01482311234). All experimental procedures were performed in accordance with the Guide for the Care and Use of Laboratory Animals issued by the United States National Institutes of Health.RESULTS AND CONCLUSION: Our study results show that the function of microglia is closely related to the iron metabolism in nigra dopaminergic neurons. Research on the rational use of microglia to prevent neuronal degeneration gives a strong impetus to the prevention and treatment of Parkinson's disease.

OBJECTIVE: To summarize the clinical datas of thepatients with invasive laryngeal fungal infections in, discuss pathogenesis and treatment methods. METHOD: Eleven cases of invasive laryngeal fmycosis who were collected from September 2006 to February 2010 with electronic laryngoscopy, aspirate smear and culture and tissue biopsy for pathological diagnosis, were restrospectively analyzed. Those patients were received iv fluconazole, treatment of Oxygen Atomization of amphotericin B solution and taking itraconazole orally. The hepatic and renal functions of the patients were monitored in the course of treatment. RESULT: All the cases were diagnosed of invasive laryngeal mycosis. 1 patient showed liver dysfunction in the second week during treatment. And continuing the treatment after using liver protection drugs. All symptoms of the patients were improved and no recurrence happened during the 1-6 years of follow-up. CONCLUSION Invasive laryngeal fmycosis was correlated with occupation exposure, abusing of antibiotics and low immunity. Laryngeal mycosis was Diagnosised mainly depended on the pathological examination. The positive rates of the secretion smear was low. The effects of iv fluconazole, Oxygen Atomization of amphotericin B 2-4 weeks, and 4 weeks of taking itraconazole orally were safety and reliable.
