This study is to provide reference for the proper understanding of the content of " Promoting innovation and access to quality, safe, efficacious, and affordable medicines for children” resolution of 69th World Health Assembly (WHA), and facilitate the policy making and implication of the Resolution. Through descriptive analysis, the author introduce the proposal background and approving process of the resolution, and interpret the resolution content. The approval of " Promoting innovation and access to quality, safe, efficacious, and affordable medicines for children” at WHA represents China's international discourse right on improving the basic medical service among children, the most vulnerable population; highlights China's responsibility and magnitude of a great nation. It is an effective promotion for China's new medical reform and the implication of the Millennium Development Goals (MDGs), as well as a great contribution to the global health of children from China.
Objective To investigate the lung involvement in Chinese patients with systemic sclerosis ( SSc) and its functional impact. Methods 68 patients with SSc were enrolled in Scleroderma study of PUMCH ( Peking Union Medical College Hospital) . All the patients underwent high resolution computed tomography ( HRCT) , pulmonary function testing, 6-minute walk testing, and echocardiography. And 36 patients filled in the Saint George’s Respiratory Questionnaire ( SGRQ) for assessment of healthrelated quality of life. Results HRCT revealed interstitial lung disease ( ILD) in 52 ( 76. 5% ) patients, 20 out of them without respiratory symptoms. Reticular opacification, ground-glass opacity ( GGO) , traction bronchiectasis, and honeycomb were presented respectively in 80.8% , 73.1% , 59.6% , and 30.8% of patients with SSc-ILD. Fibrosis was the predominant HRCT finding, and pure GGO ( in the absence of reticulation or architectural distortion) was only present in 8 ( 15. 7% ) patients. 57 (83.8% ) patients presented with diffusion defect, with most of them having moderate to severe impairent. Reduced FVC or TLC presented in 20 ( 29.4% ) and 28 ( 41.2% ) of patients respectively. The significant correlation was observed between the DLCO and the extent of ILD on HRCT ( rs = -0.476, P =0.000) . DLCO showed significant correlations with all the four components of the SGRQ ( Plt;0.05) . Significant correlations were also observed among the SGRQ scores and SpO2 ( maximum desaturation) or Borg index. Stepwise multiple regression analysis confirmed that the DLCO, SpO2 , and Borg index contributed to the SGRQ. Conclusions Lung involvement in Chinese SSc patients is common and insidious. The HRCT features of SSc-ILD are predominant fibrosis plus GGO, indicating little reversibility. Thus HRCT should be performed routinely in newly diagnosed SSc patients for early screening of lung involvement. The lung function defect of SSc is characterized by reduced diffusing capacity, and DLCO show better correlations with HRCT abnormities or SGRQ than FVC or TLC. Thus DLCO is of great value for early detection or severity assessment of SSc-ILD. SGRQ can be used to examine the health related quality of life of SSc patients and may reflect severity of lung involvement.
