Smoking and exposure to second hand smoke are the deadly killer of human health. Tobacco kills more than one million people each year in China. According to 2015 Chinese adult tobacco survey, the number of smokers in China increased by 15 million during five years, from 301 million in 2010 to 316 million in 2015. Smoking addiction is a chronic recurrent disease, and its pathogenesis is associated with the mesolimbic dopamine system. In recent years, domestic and overseas scholars studied the brain function of smoking addicts through resting state functional magnetic resonance imaging (fMRI), and found that the brain functional activity of smoking addicts has changed. fMRI can help us understand the mechanism of tobacco dependence, and provide the evidence of diagnosis, treatment and health management of tobacco dependence. In this paper, the present study situation and the application in the field of the treatment and management of smoking cessation of fMRI in smoking addicts are reviewed.

Objective To express the recombinant protein VP1-Z, and investigate whether VLP-Z has the physiological functions like as wild-type VLP. Methods The expression plasmid pET15b-VP1-Z was introduced into competent E. coil BL21 (DF3)/pLys cells by transformation, and the expression of re-combinant protein VP1-Z was induced by incubation of the cells with IPTG. The protein was prepared as pre-viously described for wild-type VLP. The morphous of VLP-Z were observed by electron microscopy, and the physiological functions of VLP-Z were investigated by hemagglutination test and by immunofluorescence. Re-sults The purified VLP-Z composed of VP1-Z possessed hemagglutination activity and yielded a prominent band of 50×10~3 on SDS-PAGE and staining with Coomassie Brilliant Blue. The VLP-Z exhibited virus-like particles structure like as wild-type VLP with a diameter of 45-50 nm, which was slightly bigger than that of wild-type VLP(42-45 nm). In immunofluorescence test, VP1-Z was detected within the cytoplasm and nu-cleus after HeLa cells were inoculated with VLP-Z. Conclusion The physiological functions of recombinat-ed protein VLP-Z were comparable with wild-type VLP.

Objective To explore the relative factors of polycystic ovarian syndrome (PCOS) in infertile women.Methods Ninety-eight infertile women diagnosed PCOS at affiliated hospital of the Chinese People's Armed Force Logistic college from Jan.2008 to Dec.2012 were served as PCOS group.Two hundred and eighty infertile women with normal ovarian structure according to laparoscopic examination result were selected as control group.The general information,factors related infertile and laparoscopic examination of the two groups were recorded.Results Fifty-one cases (52.0％) in PCOS group were with menarche age earlier than 13 years old,higher than that of control group (113 (40.4％),x2 =4.03,P ＜ 0.05).Eleven cases (11.2％) in PCOS group were with abnormal menstruation cycle,higher than that of control group (12 (4.3％),x2 =6.12,P ＜ 0.05).The incidence of pelvic adhesions in PCOS group was lower than the control group(60(21.1％) vs.224(40.4％),x2 =13.70,P ＜0.05).Irregular menstruation cycle was risk factor of PCOS (OR=1.770,95％ CI:1.09-2.88,P =0.002).Conclusion Women with earlier menarche and irregular menstruation cycle should be paid more attention in terms of PCOS,early screening,discovery,prevention and treatment,so as to reduce the incidence of PCOS induced infertility and the long-term complications.
