To explore the pharmacogenomic markers that affect the platinum-based chemotherapy response in non-small-cell lung carcinoma (NSCLC), we performed a two-cohort of genome-wide association studies (GWAS), including 34 for WES-based and 433 for microarray-based analyses, as well as two independent validation cohorts. After integrating the results of two studies, the genetic variations related to the platinum-based chemotherapy response were further determined by fine-mapping in 838 samples, and their potential functional impact were investigated by eQTL analysis and in vitro cell experiments. We found that a total of 68 variations were significant at P < 1 × 10-3 in cohort 1 discovery stage, of which 3 SNPs were verified in 262 independent samples. A total of 541 SNPs were significant at P < 1 × 10-4 in cohort 2 discovery stage, of which 8 SNPs were verified in 347 independent samples. Comparing the validated SNPs in two GWAS, ADCY1 gene was verified in both independent studies. The results of fine-mapping showed that the G allele carriers of ADCY1 rs2280496 and C allele carriers of rs189178649 were more likely to be resistant to platinum-based chemotherapy. In conclusion, our study found that rs2280496 and rs189178649 in ADCY1 gene were associated the sensitivity of platinum-based chemotherapy in NSCLC patients.

Objective: To explore the change of fractional exhaled nitric oxide (FeNO) and its correlation with forced expiratory volume in the ifrst second (FEV1), the ifrst second forced expiratory volume percentage of forced vital capacity (FEV1/FVC) in bronchial asthma and chronic obstructive pulmonary disease (COPD). Methods: FeNO, FEV1 and FEV1/FVC were measured in 57 suspected asthmatics (21 acute onsets, 12 non-acute and 24 non-asthma), 38 COPD patients (25 acute exacerbations and 13 stable stages) and 26 healthy subjects. Results: In the 57 suspected asthmatic patients, when the optimal cut off value of FeNO was 20.15 PPb, which was used to diagnose asthma and differentiate asthma and non-asthma, the positive predictive value, the negative predictive value, the sensitivity and the speciifcity was 94.1%, 95.7%, 97.0%, and 91.7% respectively. hTere was signiifcant difference in the FeNO level between the 33 asthmatics and 26 healthy subjects (P<0.05). There was also significant difference in the FeNO level between the acute onset and the non-acute (P<0.05), but not in the FEV1 and FEV1/FVC level (bothP>0.05). hTere was no signiifcant correlation between FeNO and FEV1, FEV1/FVC in patients with asthma (r=-0.186,-0.236, bothP>0.05). hTere was signiifcant difference in the levels of FeNO, FEV1 and FEV1/FVC between the 38 COPD patients and the 26 healthy subjects (all P<0.05), and also between the 25 acute exacerbations and 13 stable COPDs (allP<0.05), but not between the 13 stable COPDs and 26 healthy subjects (allP>0.05). FeNO was not correlated with FEV1 and FEV1/FVC level in COPD patients (r=-0.167,-0.285, bothP>0.05). Conclusion: FeNO level is increased obviously in patients with asthma. hTe optimal cut off value of FeNO at 20.15 PPb can differentiate asthma and non-asthma with high sensitivity and speciifcity. FeNO is higher for the acute onset than non-acute, which may be useful to evaluate the control degree. FeNO level is increased in COPD patients in the acute exacerbations, but there is no change in stable COPD patients compared with the healthy subjects.

Objective To elucidate intracellular transcription factor activation of C_7~T_5 dorsal root ganglia in rats recurrently infected with respiratory syncytial virus (RSV). Methods Eighty 1~2 weeks old Sprague-Dawley rats were randomly divided into 2 groups: a control group and a RSV-infection group. The rats in the RSV-infection group were infected with 5 ×10~5 U/mL RSV once a week and the rats in the control group were treated with culture medium without RSV. Airway response was measured after 8 weeks. Lung tissue was submitted for HE staining and in situ hybridization. The C_7~T_5 dorsal root ganglia were obtained for the preliminary screening of the intracellular transcription factors by TranSignal~(TM) protein/DNA combo array. Nuclear protein of C_7~T_5 dorsal root ganglia were extracted and submitted to Western blot. Results Airway response in the RSV-infection group was higher than that in the control group (P<0.05). HE staining showed inflammatory cell infiltration, and in situ hybridization demonstrated positive RSV RNA in the RSV-infection rat lung which was not present in the control group, thus validating the efficacy of our model. TranSignalTM protein/DNA combo array screening showed that 55 transcription factors increased by at least 2 folds in the C_7~T_5 DRG cells of the RSV-infection group. The transcription factors Smad and interferon regulatory factor (1 or 2) were the 2 most upregulated transcription factors identified by combo array screening (59 and 43 fold increase compared with the control, respectively). Western blot confirmed Smad(1/2/3) and IRF-1 upregulate while IRF-2 remained unchanged. Conclusion Respiratory syncytial virus infection results in airway hyperresponsiveness and transcription factor activation in C7~T5 spinal adorsal root ganglia in rats, which may contribute to airway nerve network dysfunction and airway hyperresponsiveness.
