Objective To explore the relationships among pulmonary function,DVH and acute radiation pneumonitis after three-dimensional conformal radiation treatment in patients with non-small-cell lung cancer.MethodsPulmonary function tests were conducted on 68 inoperable patients (male 42,female 26,median age 52,KPS≥80) before and after three months radiotherapy respectively.After 3 months of follow-up,radiation pneumonitis were graded,and V20,V30 and MLD were derived from dose volume histogram (DVH).ResultsAll patients were treated with radiotherapy at the irradiation dose of 60~70Gy.Acute radiation pneumonitis occurred in 24 patients with 11 Grade Ⅰ,7 Grade Ⅱ,3 Grade Ⅲ,3 Grade Ⅳ.There were no significant difference between the pre-irradiation and the three months after irradiation for FVC (P>0.05).But there were significant different between pre-irradiation and three months after irradiation for FEV1.0 and DLCO (P<0.05).V20,V30 and MLD were observed in patients treated with high radiation pneumonitis.ConclusionsThere were close relationships among pulmonary function,DVH and radiation pneumonitis in patients with non-small cell lung cancer.

BACKGROUND/AIMS: Several studies have demonstrated that sleep problems are associated with functional gastrointestinal disorders (FGIDs): irritable bowel syndrome (IBS), functional dyspepsia, etc, but the relationship between excessive daytime sleepiness (EDS) and FGIDs has not been systematically studied in the general population. This study aims to explore the relationship between EDS and specific types of FGIDs and the effect of the number of FGIDs on EDS. METHODS: A sample of 3600 individuals (aged 18–80 years) was selected from 5 regions in China using a randomized, stratified, multi-stage sampling method. EDS was measured by the Epworth Sleepiness Scale, while gastroesophageal reflux disease (GERD) and other FGIDs were assessed by Reflux Disease Questionnaire and the Rome II diagnostic criteria, respectively. RESULTS: The survey was completed by 2906 individuals (response rate: 80.72%), and 644 individuals (22.16%) had EDS. EDS was significantly associated with ulcer-like dyspepsia (OR, 2.50; 95% CI, 1.08–5.79), diarrhea-predominant IBS (OR, 2.00; 95% CI, 1.09–3.66), alternating IBS (OR, 2.32; 95% CI, 1.30–4.13), functional constipation (OR, 1.68; 95% CI, 1.20–2.35), and GERD (OR, 1.72; 95% CI, 1.08–2.72). Risk of EDS increased along with the increasing numbers of FGIDs: with 1 FGID (OR, 1.72; 95% CI, 1.37–2.15); with 2 FGIDs (OR, 2.43; 95% CI, 1.63–3.62); and with 3 or more FGIDs (OR, 3.26; 95% CI, 1.37–7.78). CONCLUSIONS: FGIDs, such as ulcer-like dyspepsia, diarrhea-predominant IBS, alternating IBS, functional constipation, and GERD, were significantly associated with EDS. Those who suffered from more kinds of FGIDs were more susceptible to EDS.
