To better understand the etiology of begomovirus epidemics in regions under invasion we need to know how indigenous and invasive whitefly vectors respond to virus infection. We investigated both direct and indirect effects of infection with Tomato yellow leaf curl virus （TYLCV） on the performance of the invasive Q biotype and the indigenous Asian ZHJ2 biotype of whitefly Bemisia tabaci. The Q biotype performed better than the ZHJ2 biotype on either uninfected or virus-infected tomato plants. However, virus-infection of host plants did not, or only marginally affected, the performance of either biotype of whiteflies in terms of fecundity, longevity, survival, development and population increase. Likewise, association of the vectors with TYLCV did not affect fecundity and longevity of the Q or ZHJ2 biotypes on cotton, a non-host of TYLCV. These results indicate that the alien Q biotype whitefly, but not the indigenous ZHJ2 biotype, is likely to become the major vector of TYLCV in the field and facilitate virus epidemics.

Background Chronic obstructive pulmonary disease （COPD） is thought to be an inflammatory immune response disease. In most cases, the disease is caused by cigarette smoke, but it has been demonstrated that only 10% to 20% of smokers will definitely suffer from COPD. Dendritic cells （DCs） are considered to be the promoter of immune ***, the underlying mechanisms involved are still unrevealed. In this study, we aimed to investigate the quantitative differentiation of pulmonary DC in smokers with or without COPD to explore the possible role of DCs in smokers suffering *** Peripheral lung specimens from non-smokers without airflow obstruction （control group, n=7）, smokers without airflow obstruction （smoker group, n=7） and patients with COPD （COPD group, n=7） were investigated to detect the quantity of S-100 and CD1a positive cells by immunohistochemical or immunofluorescent *** In smokers with COPD, the number of S-100＋ DCs was higher than in the controls and smokers without COPD （P 〈0.01 and P 〈0.05） and there was a higher number of S-100＋ DCs in smokers with COPD than in smokers without COPD, but without a significant difference （P 〉0.05）. An inverse correlation was found between the number of DCs and forced expiratory volume in the first second （FEV1）% pred （r=-0.75, P 〈0.05）, which was also found between the number of DCs and FEV1/forced vital capacity （FVC）（r=-0.72, P 〈0.05）. The mean number of CD1a＋ DCs, increased from non-smokers to non-COPD smokers to COPD patients, with significant differences between each group （P 〈0.01）.Conclusions The quantity of DCs significantly increased in smokers with COPD compared with non-smokers or smokers without COPD. The results suggest that DCs may play an important role in the pathogenesis of smoking-induced COPD, and the upregulation of DCs may be a potential maker to identify the smokers who have more liability to suffer from COPD.

Background Exposure to cigarette smoke stimulates the proliferation of human pulmonary artery smooth muscle cells （HPASMCs） in vivo and in vitro. However, the molecular mechanism remains unclear. This study aimed at investigating the role of signaling pathways involving protein kinase C alpha （PKCα） and cyclin D1 in the cigarette smoke extract （CSE）-induced HPASMCs *** Synchronized HPASMCs were treated with different concentrations of CSE. Cell proliferation was evaluated by 3-（4,5-dimethylthiazol-2-yl）-2,5-diphenyttetrazolium bromide （MTT） assay and cell counting. Cell cycle was analyzed by flow cytometry with propidium iodide staining. Activation of PKCα was measured by detecting the expression of PKCαprotein in the cytosolic and membrane fractions using Western blotting analysis. Small interfering RNA （siRNA） was used to knockdown PKCα and cyclin D1. The cyclin D1 mRNA was assessed by real-time RT-PCR. The PKCα and cyclin D1protein levels were detected by Western *** Low concentrations of CSE （1%-10%） stimulated proliferation of HPASMCs, with its maximal effect at 5%.CSE （5%） led to PKCα activation. Inhibition of PKCα activity using G（o） 6976 or siRNA-mediated knockdown of PKCα significantly attenuated CSE-induced cell proliferation and G1/S transition. Cyclin D1, one of key regulators of G1/S transition, was found to be upregulated by 5% CSE at both the mRNA and protein levels. CSE-stimulated cellproliferation and G1/S transition was abolished by cyclin D1 siRNA. Moreover, G（o） 6976 or PKCα siRNA significantlysuppressed CSE-induced upregulation of cyclin D1 at both the mRNA and protein *** PKCα-cyclin D1 pathway at least partially mediates the CSE-induced proliferation in HPASMCs.

利用Gleeble-1500D热力模拟试验机,对316LN钢进行温度为950~1200℃,应变速率分别为0.005、0.05、0.5和1s-1的热力模拟试验。借助扫描电镜（SEM）对断口进行观察,研究316LN钢的高温塑性及高温断裂机制。结果表明：316LN钢高温断裂为韧性断裂,随着温度和应变速率的增加,韧窝尺寸增大,深度增加,塑性增加。同时,采用回归方法构建了断裂应变、塑性指标（延伸率和断面收缩率）分别与变形条件（温度和应变速率）的关系模型,应用这些模型可以计算一定条件下316LN钢的断裂应变、延伸率和断面收缩率,对制定316LN钢的锻造工艺有一定的指导作用。
