Twenty-seven ERF transcription factor family genes were isolated from Arnebia euchroma, with an average size of 1,010 bp, each gene encoded a 212 amino acids on average. The gene structure and expression of physicochemical properties, subcellular localization, signal peptides, senior structural domains and conservative forecasting, and analysis of A. euchroma were studied comparing with ERF gene gi261363612 of Lithospermum erythrorhizon, and phylogenetic analysis of A. euchroma ERF family was carried out. The results showed the existence of three conserved domains in this family, the senior structure based on random coil and it clustered into CBF/DREB and ERF subfamilies.

OBJECTIVE To study the mechanism of loganin,the effective componet of Cornus officinalis,on protecting the glomerulus mesangial cell (GMCs) injured by advanced glycation end products (AGEs).METHODS GMCs were divided into control,model (AGEs: 200mg/L),loganin (0.1,1,10μmol/L) groups.The cell proliferation,FN and COL-Ⅳ secretion,microstructure lesions,RAGE,SphK1,S1P and TGF-β protein expressions were measured.RESULTS AGEs induced cell proliferation,FN and COL-Ⅳ secretions,microstructure lesions,RAGE,SphK1,S1P and TGF-β protein expressions were suppressed by loganin.CONCLUSION Loganin can improve the AGEs induced GMCs injury by regulating the AGEs/RAGE/SphK1 signal pathway,and then ameliorate the diabetic nephropathy.

Objective To investigate the status quo of smoking cessation and analyze factors influencing smoking cessation in cigarette smoking patients with coronary artery disease(CAD).Method A total of 350 smoking patients with CAD was surveyed by questionnaire,logistic regression analysis was performed to analyze factors influencing smoking cessation.Results Incidence of smoking cessation was 57.1%(200/350)in this cohort.Patients were divided into two groups,the elderlv(>65 years old,n=111)and the young group(≤65 years old,n=239).The smoking cessation rate in the elderlv group is significantly higher than in the young group(71.2%vs.50.6%,P<0.001).Aged patients and patients with high cultural level are easier to give up smoking.Logistic analysis showed that age≤65 years old (OR=2.336,P=0.004),low cultural level(OR=1.310,P=0.028),PCI(OR=0.261.P<0.001).coronary artery bypass graft(OR=0.107,P=0.004),total family income>4000 RMB/month (OR=1.828,P=0.003)are risk factors for failed smoking cessation.There are 76 patients smoking again in current smokers,most due to lack of self-control(76.3%).Compared to the elderly group,there is a higher proportion of smoking again due to the need of daily communication and work in the young group.Conclusions We still need to raise the awareness of smoking cessation for smoking patients with CAD.Following factors should be focused for tobacco control in CAD patients:younger age,lower cuItural level,not treated with PCI or CABG,patients with smoking family members.higher body mass index and higher total family income.

Objective To analyze the status of quality indicators(QI) on specimen acceptability and establish preliminary qual ity specification.Methods Web based External Quality Assessment system was used to collect data of laboratories partici pated in "Medical quality control indicators in clinical laboratory" from 2015 to 2017,including once in 2015 and 2017 and twice in 2016.Rate and sigma scales were used to evaluate incorrect sample type,incorrect sample container,incorrect fill level and anticoagulant sample clotted.The 25th percentile (P25) and 75th percentile (P75) of the distribution of each QI were employed to establish the high,medium and low specification.Results 5 346,7 593,5 950 and 6 874 laboratories sub mitted the survey results respectively.The P50 of biochemistry (except incorrect fill level),immunology and microbiology reach to 6σ.The P50 of clinical laboratory is 4 to 6σ except for incorrect sample container.There is no significant change of the continuous survey results.Based on results in 2017 to establish the quality specification,the P25 and P75 of the four QIs is 0 and 0.084 4 ％,0 and 0.047 6 ％,0 and 0.114 2 ％,0 and 0.078 4 ％,respectively.Conclusion According to the results of the survey,most laboratories had a faire performance in biochemistry,immunology and microbiology,and clinical laboratory needs to be strengthened.Laboratories should strengthen the laboratory information system construction to ensure the actual and reliable data collection,and make a long time monitoring to achieve a better quality.

Chinese Pharmacopoeia provides nine pesticide Maximum Residual Limits(MRLs) of traditional Chinese medicines(TCMs), The number of pesticides used in production are far more than those listed in pharmacopoeia. The lack of the standards make it's hard to reflect the real situation of pesticide residues in TCMs correctly. The paper is aimed to analyze the data of pesticide residues in TCMs from 7 089 items in 140 reports, and judging the exceedance rate of pesticides in TCMs using the MRLs of European pharmacopoeia，which is widely accepted in many countries. The results show that：①Pesticide residues in 18 kinds of TCMs are higher than MRLs，while in 137 kinds are below MRLs, such as Atractylodis Macrocephalae Rhizoma, Menthae Haplocalycis Herba and Fritillariae Thunbergii Bulbus. The average exceedance rate of all TCMs is 1.72%. The average exceedance rates of organochlorine, organophosphorus and pyrethroid are 2.26%, 1.51%, 0.37%，respectively. ②The average exceedance rate of pesticides is 2.00%, and the exceedance rate is more than 5%, accounting for 8.33%, the exceedance rate is between 1%-5%, accounting for 18.75%. the exceedance rate is between 0%-1%, accounting for 18.75%. The remaining 29 kinds of pesticides were not exceeded, accounting for 60.42%.Some reports like Greenpeace's organization exaggerated the pesticide residues in TCMs.But the pesticide residue question is still worthy of attention, so we proposed to amend the Chinese Pharmacopoeia pesticide residues standards, to increase the pesticide species of traditional Chinese medicine in production on the basis of retaining the existing types of pesticide residues, to strengthen the system research of pesticide residues in TCMs, providing a basis for making standard and promoting import and export trade in TCMs.
