PurposeTo measure the areas and diameter lines of bronchi at acute exacerbation and at remission period in patients with chronic obstructive pulmonary disease (COPD) using CT, and to explore the correlation between the two periods and evaluate the comprehensive assessment in diagnosing COPD exacerbation.Materials and Methods Fifty-two COPD patients were scanned with 64-row spiral CT on chest and PFT at acute exacerbation and at remission period. The areas and diameter lines of apical segmental and the sub-segmental bronchi of the right upper lobe in the patients were measured at the two periods, including indicators such as wall thickness (WT), thickness-diameter ratio (TDR), wall area (WA), percentage of wall area (WA%). The differences of those indicators at the two periods were compared with such factors of COPD comprehensive assessment as forced expiratory volume at the first second% (FEV1%), percentage of forced expiratory volume in first second to forced vital capacity (FEV1/FVC), COPD assessment test (CAT), modified medical research council questionnaire (mMRC) for assessing the severity of breathlessness, 6-minute walking distance (6MWD). Results The patients had significant differences between acute exacerbation period and remission period in the indicators of COPD comprehensive assessment like FEV1%, FEV1/FVC, CAT, mMRC and 6MWD (t=-4.119,-2.583, 4.012, 3.321 and-3.892,P<0.05). Compared with those at remission period, the WT, TDR, WA and WA% of sub-segmental bronchi were all higher at acute exacerbation period (t=3.025, 2.341, 2.204 and 2.124, P<0.05); only TDR of segmental bronchi showed significant difference between the two periods (t=2.990,P<0.05). The correlation of sub-segmental bronchi with FEV1%, FEV1/FVC, CAT, mMRC and 6MWD was more significant than that of segmental bronchi with those indicators at the two periods.Conclusion The COPD comprehensive assessment can help diagnose COPD at acute exacerbation period; MSCT shows the remodeling of segmental and sub-segmental bronchi and the changes on the airway wall, and the quantitative measurement of sub-segmental bronchi has correlation with the differences of indicators in the comprehensive assessment; COPD comprehensive assessment seems to be more valuable than PFT in the estimation of COPD at acute exacerbation.

OBJECTIVE: Chengde is a city with many corneal blindness patients In north China. Lacking of corneas donation is the main reason which prevents corneal transplantation. Survey was made by questionnaire in Chengde to evaluate the current situation and the influential factors of corneal donation.METHODS: Survey was made in 3 200 Chengde residents aged 18 years or older, includes outpatients and inpatients of ophthalmology, some undergraduate students and people met accidentally in park, supermarket, station and centre for elders.48.6% are male and 51.4% are female. Self-made questionnaire includes general state, questions about cornea donation and factors influencing cornea donation.RESULTS: Among 3 200 questionnaires, 2 971 were valid. The effective rate was 92.84%. Over 50% people support donating cornea. More than 40% people intend to donate their corneas and support their relatives to donate. Among the factors for not intending to donate cornea, lacking knowledge of cornea donation was the main reason accounting for 42.81%, and worrying about the misusage of donating cornea without corresponding law became the second factor, which accounting for 21.07%. It has no influence on the consciousness of cornea donation by the difference of sex and location between city and countryside.Whereasfession and level of education indeed influence the consciousness of cornea donation, which of the people from 18 to 40 years old was greater than those of over 40, medical workers was greater than those from other fields, the people graduating from secondary specialized school or higher was greater than those graduating under secondary specialized school.CONCLUSION: People in Chengde have a positive attitude towards cornea donation. It is very necessary to enhance the education of cornea donation, establish an easy and smooth way for donation may promote cornea donating. Consummate legislation is also needed for cornea donation.
