Objective: To develop the native Chinese Affective Picture System (CAPS) for future research on emotion. Methods: 852 pictures were screened out to make up of CAPS. 46 Chinese university students were collected to rate the valence, arousal and dominance by self-report in a 9-point rating scale for CAPS. Results: The standard deviations of scores on valence and dominance were greater than that on arousal. Scatter plot showed that the score distribution on the dimension of valence and arousal was wide in CAPS. Conclusion: Though IAPS (International Affective Picture System) is highly internationally-accessible, there are still significant differences between the two sources. The native Chinese Affective Picture System is necessary.

Polycyclic aromatic hydrocarbons ( PAHs) are ubiquitous environmental pollutants, whose carcinogenicity is determinated.The mechanism of their carcinogenicity: PAHs are able to combine with aryl hydrocarbon hydrocarbon receptor ( AhR ) , resulting in some toxicity and carcinogenicity.AhR is a ligand-dependent activation transcription factor, which is activated by a large variety of ligands, regulating the expression of a series of gene involved in metabolism, and participating in important biological processes, such as singal transduction, cell proliferation,differentiation and apoptosis,and so on.Besides, it's closely related with the tumor development.Thus, it will provide a new approach for cancer prevention and treatment to study the role of PAHs and AhR in the development of tumor.

Objective To investigate the association of transforming growth factor (TGF) gene rs1800469 (TGF1-509C/T) and rs1982073 (TGF1+869T/C) single nucleotide polymorphisms (SNP) with susceptibility of lung cancer. Methods The case group consisted of 193 histologically diagnosed lung cancer patients, and control group of 211 controls were selected from cancer-free patients at the same time. The single nucleotide polymorphisms of rs1800469 (TGF1-509C/T) and rs1982073(TGF1+869T/C) were analyzed by real-time fluorescent quantitative reverse transcription polymerase chain reaction method. The demographic characteristics, correlated risk factors of exposure and SNP between 2 groups were compared. Results The genotype distribution frequency of TGF1+869T/C and TGF1-509C/T in control group was accorded with Hardy-Weinberg law (P>0.05). The TT, TC and CC genotype distribution frequency in TGF1+869T/C in case group were 16.1%(31/193), 55.4%(107/193) and 28.5%(55/193), while these in control group were 22.3% (47/211), 50.2% (106/211) and 27.5% (58/211), and there were no statistical differences (P>0.05). The TT, TC and CC genotype distribution frequency in TGF1-509C/T in case group were 28.0%(54/193), 56.0%(108/193) and 16.1%(31/193), while these in control group were 27.0% (57/211), 51.2% (108/211) and 21.8% (46/211), and there were no statistical differences (P>0.05). The allele in rs1800469 (TGF1-509C/T) and rs1982073 (TGF1+869T/C) showed no association with lung cancer (P>0.05). Conclusions TGF gene SNP may not be associated with susceptibility to lung cancer in Han Chinese in North China.

CONCLUSION: We can discriminate chrysanthemums from the different producing areas macroscopically and holistically by IR spectroscopy.IR spectroscopy can give us the digital descriptions of TCM,so it is a new analytical method to discriminate TCM.

Objective To investigate the relationship between hyperhomocysteinaemia and unstable angina pectoris (UAP). Methods Selected 159 patients with senile hypertension combined with angina pectoris from April 2013 to April 2014, 78 cases of hyperhomocysteinaemia patients as observation group, 81 cases of simple hypertension patients as control group. All of the patients were performed coronary angiography examination, using the Gensini score method calculated the integral of the coronary lesions (CAS). Detected the level of the serum homocysteine (Hcy), hypersensitive C-reactive protein (hs-CRP), fasting blood glucose (FBG) and blood lipid levels. Results The gender, age, the levels of FBG and lipid in two groups had no significant differences ( P>0.05). The incidence of UAP,CAS and hs-CRP in observation group were 44.9%(35/78), (44.34±10.67) scores,(4.31±1.01)μg/L, in control group were14.8%(12/81), (30.24±8.76) scores, (2.13±0.95)μg/L. The incidence of UAP, CAS and hs-CRP in observation group were significantly higher than those in control group ( P<0.05). The levels of serum Hcy,TC,TG,LDL-C, hs-CRP, HDL-C in UAP patients of observation group and control group were (23.21 ± 7.35) and (8.86 ±2.43) μmol/L, (6.54 ±0.75) and (6.67 ±0.82) mmol/L, (1.84 ±0.95) and (1.62 ±0.83) mmol/L, (4.65±0.78) and (4.42±0.72)mmol/L,(5.15±1.24) and(3.21±1.15) mg/L, (1.02±0.32) and(1.01±0.35) mmol/L. The levels of serum Hcy,TC,TG,LDL-C, hs-CRP, HDL-C in SAP patients of observation group and control group were (12.54±4.37) and (6.52±1.36)μmol/L, (4.23±0.54) and (4.43±0.57) mmol/L, (1.45 ±0.76) and (1.25 ±0.68) mmol/L, (2.67 ±0.45) and (2.43 ±0.43) mmol/L, (3.02 ±1.13) and (1.52±0.98) mg/L, (1.24±0.36) and (1.26±0.34) mmol/L.There were significant differences (P<0.05). Multi-factor Logistic regression analysis showed that the senile H-type hypertension was independent risk factor of UAP (OR=4.324, 95%CI 2.463-6.874, P=0.001). Conclusions The levels of serum Hcy is closely related to the stability of the coronary artery atheromatous plaque and lesion severity of coronary artery. The senile H-type hypertension is independent risk factor of UAP.
