Objective To determine the level of awareness of the hazards of tobacco smoking and secondhand smoke inhalation among adults in China. Methods Household surveys were conducted with a total of 13 354 respondents aged 15 years or over from 100 counties of 28 Chinese provinces using a stratified multi-stage geographically clustered sample design. Results The findings revealed that 81.8% of the population was aware that smoking causes serious diseases, and 27.2% and 38.7% were aware that smoking causes stroke and heart attack, respectively. Only 64.3% of respondents were aware that secondhand smoke can cause serious diseases, and 27.5%, 51.0%, and 52.6% were aware that secondhand smoke causes heart disease in adults, lung disease in children and lung cancer in adults, respectively. Awareness regarding smoking-related hazards across all participants was significantly associated with several factors, including gender, smoking status, urban/rural residency, education level and exposure to tobacco control publicity in the last 30 days. Awareness regarding tobacco-related hazards in smokers was significantly associated with urban/rural residency, education level, exposure to tobacco control publicity in the last 30 days, and physician＇s advice. Awareness relating to the hazards of inhaling secondhand smoke was associated with smoking status, urban/rural residency, age, education level, and exposure to tobacco control publicity in the last 30 days. Medical professionals were found to know more about the health hazards of tobacco compared with people in other types of employment. Conclusions Overall awareness of the health hazards of tobacco has improved in the last 15 years in China, but is still relatively poor. Improved means of communicating information and more effective warning labels on cigarette packaging are necessary for increasing public awareness of tobacco hazards, particularly among rural residents and people with less education.

Do rice water weevils and rice stem borers compete when sharing a host plant?

Journal of Zhejiang University-Science B(Biomedicine & Biotechnology) 2008年第7期9卷 572-577页

The rice water weevil （RWW） Lissorhoptrus oryzophilus Kuschel （Coleoptera： Curculionidae） is an invasive insect pest office Oryza sativa L. in China. Little is known about the interactions of this weevil with indigenous herbivores. In the present study, adult feeding and population density of the weevil, injury level of striped stem borer Chilo suppressalis （Walker）（Lepidoptera： Pyralidae） and pink stem borer Sesamia inferens （Walker）（Lepidoptera： Noctuidae） to flee, as well as growth status of their host plants were surveyed in a rice field located in Southeastern Zhejiang, China, in 2004 with the objective to discover interspecific interactions on the flee. At tillefing stage, both adult feeding of the weevil and injury of the stem borers tended to occur on larger tillers （bearing 5 leaves） compared with small tillers （bearing 2-4 leaves）, but the insects showed no evident competition with each other. At booting stage, the stem borers caused more withering/dead hearts and the weevil reached a higher density on the plants which had more productive tillers and larger root system; the number of weevils per tiller correlated negatively with the percentage of withering/dead hearts of plants in a hill. These observations indicate that interspecific interactions exist between the rice water weevil and the rice stem borers with negative relations occurring at booting or earlier developmental stages of rice.

BACKGROUND The Janus kinase 2(JAK2) V617 F mutation is common in patients with breakpoint cluster region-Abelson1(BCR-ABL1)-negative myeloproliferative neoplasms,including polycythemia vera, essential thrombocythemia and primary myelofibrosis, but is rarely detected in BCR-ABL1-positive chronic myeloid leukemia(CML) patients. Here, we report a CML patient with both a BCR-ABL1 rearrangement and JAK2 V617 F *** SUMMARY A 45-year-old Chinese woman was admitted to our department with a history of significant thrombocytosis for 20 d. Color Doppler ultrasound examination showed mild splenomegaly. Bone marrow aspiration revealed a karyotype of 46,XX, t(9;22)(q34;q11.2) in 20/20 metaphases by cytogenetic analysis,rearrangement of BCR-ABL1(32.31%) by fluorescent polymerase chain reaction(PCR) and mutation of JAK2 V617 F(10%) by PCR and Sanger DNA *** patient was diagnosed with CML and JAK2 V617 F mutation. Following treatment with imatinib for 3 mo, the patient had an optimal response and BCRABL1(IS) was 0.143%, while the mutation rate of JAK2 V617 F rose to 15%.CONCLUSION Emphasis should be placed on the detection of JAK2 mutation when CML is diagnosed to distinguish JAK2 mutation-positive CML and formulate treatment strategies.

Multicolor photometry of the galaxy cluster A98: substructures and star formation properties

引用

Research in Astronomy and Astrophysics 2010年第1期10卷 1-21页

作者： Li Zhang Qi-Rong Yuan Xu Zhou Zhao-ji jiang Yan-Bin Yang Jun Ma jiang-Hua Wu Zhen-Yu Wu Department of Physics Nanjing Normal University Nanjing 210046 China National Astronomical Observatories Chinese Academy of Sciences Beijing 100012 China

An optical photometric observation with the Beijing-Arizona-Taiwan- Connecticut （BATC） multicolor system is carried out for A98 （z =0.104）, a galaxy cluster with two large enhancements in X-ray surface brightness. Spectral energy distributions （SEDs） covering 15 intermediate bands are obtained for all sources detected down to V - 20 mag in a field of 58′× 58′. After star-galaxy separation with colorcolor diagrams, a photometric redshift technique is applied to the galaxy sample for further membership determination. The color-magnitude relation is taken as a further restriction of the early-type cluster galaxies. As a result, a list of 198 faint member galaxies is achieved. Based on the newly generated sample of member galaxies, the dynamical substructures, A98N, A98S, and A98W, are investigated in detail. A separate galaxy group, A98X, is also found to the south of the main concentration of A98, which is gravitationally unbound to A98. For 74 spectroscopically confirmed member galaxies, the environmental effect on the star formation history is investigated. The bright galaxies in the core region are found to have shorter time scales of star formation, longer mean stellar ages, and higher interstellar medium metallicities, which can be interpreted in the context of the hierarchical cosmological scenario.

Late-time photometry of two nearby type II-P supernovae: 2004dj and 2004et

Research in Astronomy and Astrophysics 2009年第7期9卷 783-790页

作者： Tian-Meng Zhang Xiao-Feng Wang Xu Zhou Jun Ma Zhao-ji jiang jiang-Hua Wu Zhen-Yu Wu Stephane Basa NationalAstronomicalObservatories Chinese Academy of Sciences Beijing 100012 China Observatoire Astronomique de Marseille-Provence 38 rue Fric Joliot-Curie 13388 Marseille Cedex 13 France Physics Department and Tsinghua Center for Astrophysics （THCA） Tsinghua University Beijing 100084 China Graduate University of Chinese Academy of Sciences Beijing 100049 China Department of Astronomy University of California Berkeley CA 94720-3411 USA

We present late-time photometry for two bright type II-P supernovae （SNe） 2004dj and 2004et, extending over 400 d after the explosion, which are measured with a set of intermediate-band filters that have the advantage of tracing the strength variations of some spectral features. Although these two SNe II-P exhibit similar photometric evolution at earlier times, they diverge during the nebular phase. SN 2004dj shows a slow late-time decline rate with - 0.7 ±0.1 mag （100d）^-1 during the period ranging from t ≈ 200 - 300 d after the explosion, while SN 2004et shows a much faster decline rate at a comparable phase, e.g., 1.3 ± 0.1 mag （100d）^-1. The steeper decay rate seen in SN 2004et is likely due to dust formation in the explosion ejecta. Based on intermediate-band photometry, we derived the evolution of the feature lines [e.g., Hα] of SNe 2004dj and 2004et which are similar in flux at comparable phases but perhaps with significantly different decay rates. The origin of the observed variations in the continuum and the feature lines is briefly discussed.
