Objective To study the protective effect of resveratrol on lung tissue of respiratory syncytial virus(RSV) bronchiolitis mice by regulating TLR4/NF-κB pathway. Methods Thirty mice were randomly divided into control group, RSV group and resveratrol group. The mice models of RSV bronchiolitis were established, and the changes of TLR4 and NF-κB levels in lung tissues of mice were detected. HE staining and ELISA were used to detect airway inflammation, IL-6 and TNF-α levels before and after resveratrol administration. TLR4 and NF-κB protein and gene expressions were detected by Western Blot and real-time quantitative PCR. Results Compared with the control group, the levels of TLR4 and NF-κB in the lung tissues of mice with bronchiolitis were significantly increased. Airway inflammatory cell infiltration was aggravated in HE staining of lung tissue sections, and inflammatory factors IL-6 and TNF-α were significantly increased showing by ELISA. The expressions of TLR4 and NF-κB in resveratrol group were down-regulated after treatment. Conclusions Resveratrol can inhibit the release of inflammatory factors by inhibiting the TLR4/NF-κB pathway, play a protective role in mice with bronchiolitis.

Methods Ninety-eight patients with locally advanced lung cancer in radiotherapy were randomized into treatment and control groups.Patients in the treatment group took ambroxol orally at a dosage of 60 mg,three times per day for 3 months from the beginning of radiotherapy.The expression of TGF-β1 and TNF-αin plasma was analyzed.The clinical symptoms and lung diffusing capacity were monitored using high resolving power computed tomography.
