Chinese Society of Allergy Guidelines for Diagnosis and Treatment of Allergic Rhinitis
Lei Cheng,Jianjun Chen,Qingling Fu,Shaoheng He,Huabin Li,Zheng Liu,Guolin Tan,Zezhang Tao,Dehui Wang,Weiping Wen,Rui Xu,Yu Xu,Qintai Yang,Chonghua Zhang,Gehua Zhang,Ruxin Zhang,Yuan Zhang,Bing Zhou,Do 대한천식알레르기학회 2018 Allergy, Asthma & Immunology Research Vol.10 No.4
Allergic rhinitis (AR) is a global health problem that causes major illnesses and disabilities worldwide. Epidemiologic studies have demonstrated that the prevalence of AR has increased progressively over the last few decades in more developed countries and currently affects up to 40% of the population worldwide. Likewise, a rising trend of AR has also been observed over the last 2-3 decades in developing countries including China, with the prevalence of AR varying widely in these countries. A survey of self-reported AR over a 6-year period in the general Chinese adult population reported that the standardized prevalence of adult AR increased from 11.1% in 2005 to 17.6% in 2011. An increasing number of original articles and imporclinical trials on the epidemiology, pathophysiologic mechanisms, diagnosis, management and comorbidities of AR in Chinese subjects have been published in international peer-reviewed journals over the past 2 decades, and substantially added to our understanding of this disease as a global problem. Although guidelines for the diagnosis and treatment of AR in Chinese subjects have also been published, they have not been translated into English and therefore not generally accessible for reference to non-Chinese speaking international medical communities. Moreover, methods for the diagnosis and treatment of AR in China have not been standardized entirely and some patients are still treated according to regional preferences. Thus, the present guidelines have been developed by the Chinese Society of Allergy to be accessible to both national and international medical communities involved in the management of AR patients. These guidelines have been prepared in line with existing international guidelines to provide evidence-based recommendations for the diagnosis and management of AR in China.

Self-Organized Synthesis and Mechanism of SnO2@Carbon Tube-Core Nanowire
Minting Luo,Yongjun Ma,Chonghua Pei,Yujing Xing,Lixia Wen,Li Zhang 대한화학회 2012 Bulletin of the Korean Chemical Society Vol.33 No.8
SnO2@carbon tube-core nanowire was synthesized via a facile self-organized method, which was in situ by one step via Chemical Vapor Deposition. The resulting composite was characterized by scanning electron microscopy, X-ray diffraction and transmission electron microscope. The diameter of the single nanowire is between 5 nm and 60 nm, while the length would be several tens to hundreds of micrometers. Then X-ray diffraction pattern shows that the composition is amorphous carbon and tin dioxide. Transmission electron microscope images indicate that the nanowire consists of two parts, the outer carbon tube and the inner tin dioxide core. Meanwhile, the possible growth mechanism of SnO2@carbon tube-core nanowire is also discussed.
