Aim To discuss the repairing mechanism of Qinbai Qingfei Concentrated pellets to lung tissue of rats infected by mycoplasma. Method 60 Wistar rats weighting 80~100 g, male to female:1 ∶ 1) were di-vided into six groups randomly ( 10 rats in each group): blank group, model group, positive group, the high、middle and low dose groups of Qinbai Qingfei Concentrated pellets. Rats were infected through nasal intubation drip of MP. After 10 days of administration, concentrations of IL-6 , IL-8 AND TNF-α in serum of MPP rats were detected. Left pulmonary tissues of rats were collected to observe the lung tissue pathological change by HE staining and right pulmonary tissues were used to detect the transforming growth factor-beta ( TGF-β) and surface activity related protein A( SP-A) mRNA expression level by real-time quantitative PCR ( RT-PCR) and TGF-βand SP-A protein expression by (Western blot. Result Qinbai Qingfei Concentrated) pellets significantly inhibited inflammation of lung tis-sue, reduced the expression of TGF-β and increased the expression of SP-A in the lung tissue of rats infec-ted by mycoplasma. Conclusion Qinbai Qingfei Con-centrated pellets can inhibit epithelial-mesenchymal transition ( EMT ) , of alveolar type Ⅱ epithelial cells by reducing the content of TGF-β and restore the nor-mal morphology and function of the lung by increasing the expression of SP-A.

Objective To observe the clinical effect of artificial ventilation combined continuous positive airway pressure(CPAP) with removal of tracheobronchial foreign bodies for children and to explore the possibility and security of the method. Methods 60 children with tracheobronchial foreign body, underwent total intravenous anesthesia ,were randomly divided into A group and B group. Each group had 30 cases. A group was given artificial ventilation with CPAP. The bronchofibroscope was connected to anesthesia machine with side hole after induction for 3 minutes,and high fresh gas flow(10 ～ 15L/min) was given to maintain continuous positive airway pressure. B group were given high frequency jet ventilation(HFJV) ,60 ～ 100 bpm. The mask ventilation was given in stand of bronchofibroscope when SpO2 ＜ 90% and until SpO2 improved. MAP, HR, ECG, SpO2, PaO2, PaCO2 were monitored and recorded at time points: T0 (entered operation room), T1 (beginning of bronchofibroscopy), T2 (5 min after bronchofibroscopy), T3 (10 min after bronchofibroscopy), T4 (end of operation). The side effects, the rate of fail to bronchofibroscopy and the rate of intubations after operation in two groups were observed and recorded. Results The HR of post-anesthesia in two groups significantly decreased than those at T0 (P ＜ 0.01), but no difference showed in HR between two groups(P ＞ 0.05). SpO2 and PaO2 of post-anesthesia in two groups significantly increased than those at T0 (P ＜0. 01) ,PaO2 at T1 ,T2 ,T3 in A group were significantly higher than those in B group(P ＜0.05). PaCO2 gradually increased after bronchofibroscopy in two groups ,and the values in A group was significantly lower than in B group(P ＜0.05 or 0. 01). There were no significant differences in the rates of fail to bronchofibroscopy and of intubations after operation between two groups, but the total number of B group was higher. Conclusion Artificial ventilation with CPAP for children with removal of tracheobronchial foreign bodies was safe and practical, and has a better controllability, a minor effect to respiratory function, deserve popularizing.
