Background Asthma is a significant chronic health problem worldwide. Management aims at disease control by reducing functional impairment and exacerbations and improving quality of life (QoL). We report a multi-center study to survey asthma control and QoL in four cities in the Pearl River Delta. Methods The conjoint survey involved ten Hong Kong pediatric hospitals/units, two Shenzhen hospitals, two Macao hos-pitals, and two Guangzhou hospitals on asthma control (using Asthma Control Test) and QoL (Pediatric Allergic Disease Quality of Life Questionnaire, PADQLQ). Acceptability of a treatment is graded as very good/good/fair/poor. Results Good asthma control was only reported in 80% subjects in Hong Kong, but higher in sister cities (85–94%, P<0.001). Allergic rhinitis, 'incense burning', and 'smoker in family' were prevalent among the four cities. Logistic regres-sion showed better control of asthma was associated with better PADQLQ (B=?0.029, P < 0.001), better acceptability of bronchodilator (B=?1.488, P = 0.025), negatively with 'smoker in family' (B=?0.83, P = 0.015) and various PADQLQ domains. Conversely, worse PADQLQ was associated with allergic rhinitis severity (B=4.77, P <0.001), poor control of asthma (B=7.56, P <0.001), increased frequency of traditional Chinese medicine use (B=1.7, P < 0.05), increased fre-quency of bronchodilator usage (B=1.05, P < 0.05), 'smoker in family' (B=4.05, P < 0.05), and incense burning at home (B=3.9, P < 0.05). Conclusions There are some clinical and cultural differences among the four southern Chinese cities within the Guangdong province. This study identifies potentially modifiable environmental and treatment factors associated with poor asthma control and QoL for health-care interventions. Having a smoker in the family is independently associated with poor asthma control and QoL.

李炳宪、宋慧乔“今年的”掀狂潮

疯狂英语（初中天地） 2003年第20期 26-26页

作者： maggie

Viewership ratings for the drama serial"All-In"were initially lagging behind all-time favourite "Betrayal of Love". Fortunately, it garnered a strong following in Korea when the focus of the story shifted to Las Vegas, where beautiful sights and sounds were believed to have captured the attention of the audience. In a bid to stimulate viewership, broadcaster SBS had also created much hype over the love scene between lee Byung Hun and Song Hye Kyo, calling it the latter’s sexiest outing ever. The news, however, annoyed quite a number of Hye Kyo’s fans, who kept calling up the station to complain about the way their idol’s innocent image was being destroyed.
