七氟醚對哮喘小鼠氣道炎癥的影響及其作用機制研究
[Abstract]:Background asthma is a complicated and complicated chronic airway inflammatory disease, which is involved in many different inflammatory cells and cellular components. The main clinical and pathological features include airway chronic inflammation, airway hyperresponsiveness, mucus hypersecretion, and airway remodeling. Sevoflurane (SEV) is a commonly used inhalation anesthetic, and it has been reported that sevoflurane can alleviate the clinical symptoms of critically ill patients with asthma. The exact mechanism of sevoflurane has yet to be further explored. Aquaporin 5 (AQP5) is mainly expressed in lung tissue, and is a kind of channel protein which plays an important role in maintaining the balance of water metabolism of lung tissue. The study has shown that the inflammatory state of the airway can change the expression level of AQP5 in the lung tissue. The effect of sevoflurane on airway inflammation in asthmatic mice and the role of AQP5 were studied in this study. Method 1. The model of acute asthma mice was established in 24 SPF C57BL/6 mice, female, body weight 23-27 g,6-8 weeks old. In the control group, the asthma group and the sevoflurane group were divided into three groups (n = 8). In the asthma group, the sensitization was started on the first day of the model:10. mu. g of ovalbumin and 1 mg of potassium sulfate were dissolved in 0.5 ml of physiological saline solution and injected into the abdominal cavity of the mice. Excitation was started on the 14th day of the model:50 ml of 1% ovalbumin physiological saline solution was taken in 50 ml for 7 days by means of an ultrasonic atomizer and 0.5 h for each time. The model of the sevoflurane group was the same as the above, and the inhalation time was 1 hour. The control group injected 0.5 ml of the saline solution containing 1 mg of potassium sulfate in the abdominal cavity of the day 0 of the model, and started on the 14th day. The inhalation of 0.9% normal saline (50 ml) was repeated for 7 consecutive days, and once a day, 0.5 h each time. The number of inflammatory cells in BALF was measured by bronchoalveolar lavage, recovery and irrigation, and the total number of inflammatory cells in the alveolar lavage fluid (BALF) was counted, and the inflammatory mediators in BALF were determined by ELISA. IL-13 and IL-10 concentrations. An appropriate amount of the lung tissue sections, HE staining, PAS staining, the infiltration of inflammatory cells in the lung tissue, the damage of the bronchial epithelium and the alveolar structure, and the mucus secretion were observed. The expression of AQP5 in lung tissue was detected by Western blot. Establishment of a mouse model for acute asthma. Compared with the control group, the behavior of the mouse behavior of the asthma group was increased, the restlessness, the shortness of breath, and so on. Histopathology and molecular biological tests showed that the structure of the alveolar wall in the lung tissue of the asthma group was destroyed, and a large amount of inflammatory cells were infiltrated around the blood vessel and the bronchi, the wall of the air tube was increased in thickness, the epithelial cells were necrotic and the secretion of mucus increased. The total number of inflammatory cells in BALF of asthmatic group and the number of inflammatory cells, interleukin-13 (IL-13), tumor necrosis factor (TNF-1) content increased (P0.05), and the content of interleukin-10 (IL-10) was increased (P0.05). Sevoflurane inhibits airway inflammation in asthma mice. Compared with the asthma group, the damage of the lung tissue in the sevoflurane group was significantly reduced, the number of infiltration of the inflammatory cells and the amount of mucus secretion were significantly reduced, the total number of inflammatory cells in the BALF and the number of the inflammatory cells were significantly reduced, and the level of the expression of the cytokines TNF-1 and IL-13 decreased. The level of IL-10 expression was significantly increased (P0.05). The expression of AQP5 in the lung of asthmatic mice was increased by sevoflurane. Compared with the control group, the expression of AQP5 in the asthmatic group was significantly decreased, and the expression of AQP5 in the sevoflurane group was significantly increased compared with the control group (P0.05). Conclusion Sevoflurane can inhibit the airway inflammation of asthmatic mice, and its inhibitory effect on airway inflammation may be achieved by up-regulating the expression of AQP5.
