Journal of Shanghai Jiaotong University(Medical Science) 2017;37(2):155-160
Objective · To understand current smoking status and analyze its influencing factors among university students in Shanghai, and provide reference and guidance for further efforts of tobacco control in campus. Methods · A total of 4816 students from 19 col eges in Shanghai were selected by stratified multi-stage cluster sampling and the sample size in each part was decided by proportion of col eges and types of specialities. Self-administered questionnaire was conducted to understand the current tobacco use and its influencing factors were analyzed. Results · The overal smoking prevalence of col ege students in Shanghai was 5.80%. General y, smoking prevalence of junior col ege students was higher than that of undergraduates (11.27% vs 3.68%, P<0.05) and smoking prevalence of male students was higher than that of females (11.10% vs 0.95%, P<0.05). Nonsmokers endorsed higher awareness on the harm of smoking and second-hand smoking than smokers(P<0.01). Besides, nonsmokers had a more positive attitude towards tobacco control policy than smokers (P<0.01). Students who studied in the junior college, males, in the senior grade, majored in liberal arts, with higher monthly living expenses, held negative attitude in raising cigarette prices and supporting of establishing smoke-free campuses were more likely to be smokers. Conclusion · Tobacco use among university students in Shanghai deserves attention. It is necessary to carry out systematic and in-depth education to prevent and reduce smoking among the university students.
5.Expressions of transcription factor activator protein-2α, estrogen receptor-β and matrixmetalloproteinase-9 in lichen planus lesions
Chinese Journal of Dermatology 2011;44(5):339-342
Objective To determine the expressions of transcription factor activator protein-2α (AP-2α), estrogen receptor-β (ER-β) and matrixmetalloproteinase-9 (MMP-9) in lichen planus (LP) lesions and their significance. Methods Tissue samples were resected from the lesions of 30 patients with LP and normal skin of 30 human controls. An immunohistochemical method using streptavidin-peroxidase (SP) was performed to detect the expression of ER-β and MMP-9, reverse transcription-PCR and Western blot to measure the mRNA and protein expressions of AP-2α, ER-β and MMP-9 in these specimens. Results There was a significant decrease in the mRNA expressions of AP-2α (0.488 ± 0.039 vs. 1.008 ± 0.023, P < 0.01 ) and ER-β (0.365 ± 0.032 vs. 0.998 ± 0.036, P < 0.01), together with an increase in the expression of MMP-9 (1.237 ± 0.027 vs. 0.567 ± 0.015, P< 0.01) in the LP lesions compared with the control specimens; similar results were observed for the protein expressions of AP-2α, ER-β and MMP-9. In LP lesions, the expression of AP-2α was positively correlated with that of ER-β (R = 0.89, P < 0.01), but negatively correlated with that of MMP-9 (r = -0.91, P < 0.01). Conclusions The down-regulation of ER-β expression and up-regulation of MMP-9 expression may be ascribed to the abnormal regulation of upstream target genes mediated by the decreased expression of AP-2α, which may be involved in the pathogenesis of LP.
6.The progress of copy number variation and its measurement methods in autoimmune diseases
Chinese Journal of Laboratory Medicine 2013;36(11):987-991
Copy number variation (CNV) is one kind of structural variations,which exists extensively in human genome.In addition,it is the crucial source of inter-individual gene differences.Recently,with the successful development of gene array and gene sequencing,molecular methods for CNV testing are more and more standardizing and automating.Therefore,ongoing attentions have been attached to the effects and mechanisms of CNV in complicated diseases like autoimmune diseases.Molecular methods for CNV testing can be divided into two categories:target screening and the whole genome scanning platforms.Currently,the studies about CNV and autoimmune diseases mainly focused on systemic lupus erythematosus and rheumatoid arthritis.Considering the limitations of measurement methods and testing costs,it is still in the infant.

In the present study, the regulation of Vitreoscilla hemoglobin (VHb) on astragaloside IV biosynthesis was investigated. An intermediate expression vector consisting of the CaMV35S promoter fused to the vgb and nopaline synthase terminator was transferred into Astragalus membranaceus via Agrobacterium rhizogenes. The transgenic hairy roots were confirmed by PCR amplification and Southern blot hybridization. The expression of vgb in transgenic hairy roots was confirmed by RT-PCR. After 15 days cultivation, the dry weight and growth rate of transgenic hairy roots were higher than that of the non-transgenic hairy root. ELSD-HPLC analysis showed that astragaloside IV content of transgenic hairy roots was 5 to 6 times of non-transgenic hairy root control and 10 to 12 times of Radix Astragali from Shanxi Province. These results suggested that the expression of vgb promoted the growth of transgenic hairy roots, and increased the content of astragaloside IV.

Objective:To examine whether dysfunctional attitudes and cognitive bias change with fluctuations in depressive symptoms. Methods:122 patients with MDD (major depressive disorder) were assessed with DAS (dysfunctional attitude scale),CBQ (cognitive bias questionnaire) ,and HRSD (Hamilton rating scale for depression) before and after the 8-week treatment. 51 normal subjects were assessed with the DAS, CBQ and SDS as controls.Results:(1) Compared with normal controls, at the baseline MDD patients had significantly higher total DAS scores (158.2?34.6 vs. 119.3?23.4,t=8.559, P=0.000) and the score of CBQ (5.19?3.77 vs. 1.69?1.83, t=8.208, P=0.000). (2) After 8 weeks, the HRSD scores of patients reduced to Median 7.0, and the DAS and CBQ scores significantly lower than those in baseline (DAS total score from 158.2?34.6 to 143.3?29.3, t=3.611, P=0.000; the median of CBQ decreased from 5.0 to 3.0;z=4.670, P=0.000). (3) The DAS score (131.1?25.7) and CBQ score (median 3.0) of full recovery patients with full recovery remained higher than those of controls (t=2.397, P=0.018 ;z=3.990, P=0.000).Conclusion:Dysfunctional attitudes and cognitive bias were influenced by fluctuations in stata or demonstrateing stability over time. They were all state-trait features.
