Objective To investigate the changes and significance of the serum myeloperoxidase (MPO) and lipoxin (LXA4) in patients with coronary heart disease (CHD). Methods From December 2010 to February 2011,143 patients with CHD (CHD group) and 44 patients without CHD (control group) were selected. The serum high sensitive C-reactive protein (hs-CRP), MPO and LXA4 levels were assessed, and the ratio of MPO and LXA4 (M/L) was calculated. These indexes were compared between 2 groups. The influencing factors of MPO, LXA4 and M/L levels were analyzed by multifactor Logistic regression analysis. Results The serum levels of hs-CRP, LXA4, MPO, and M/L in CHD group were significantly higher than those in control group: 3.25 mg/L vs. 0.99 mg/L, 229.88 ng/L vs. 178.63 ng/L, 422.58 U/L vs. 186.85 U/L and (1.78 ± 0.52) U/ng vs. (1.02 ± 0.17) U/ng, and there were statistical differences (P<0.05). Multifactor Logistic regression analysis result showed: LXA4 level, unstable angina, acute myocardial infarction and severe elevation of white blood cell count were the impact factors for the elevation of MPO (P<0.01 or<0.05);there were no correlations between MPO level and stable angina, mild and midrange elevation of white blood cell count (P>0.05). MPO was the impact factor for the increase of LXA4 (P<0.01), and stable angina was the impact factor for the decline of LXA4 (P =0.019);there were no correlations between LXA4 level and unstable angina, acute myocardial infarction and other factors (P>0.05). Stable angina, unstable angina and acute myocardial infarction were the impact factors for the elevation of M/L (P<0.01); there were no correlations between M/L and other factors (P>0.05). Conclusions The inflammatory response in patients with CHD is accompanied by the presence of inflammation and resolution imbalance.

Objective To develop a method for the determination of DBP and DEHP in cosmetics by GC-MS. Methods The samples was extracted by methanol or acetic ether, DBP and DEHP were separated by GC and determined by MS. Results The linear range, regression equation of calibration curve and correlation coefficient were 0.5-100.0 ?g/ml, y=2?106 x-2?106, 0.999 6 for DBP respectively and 5.5-110.0 ?g/ml, y=988 223 x-7?106, 0.995 9 for DEHP respectively. Based on threefold ratio of signal and noise, as the sample was 1.0 and 0.2 g respectively, the volume was 10.0 ml, the detection limits were 1.0 and 5.0 mg/kg respectively for both DBP and DEHP. The recovery rates were 90.8%-119.0% for DBP and 90.4%-115.3% for DEHP. Relative standard deviations were 4.8%-9.8% for DBP and 6.0%-8.6% for DEHP. Conclusion This method is sensitive, accurate and high reproducible, and was applicable to the determination of DBP and DEHP in the cosmetics.

Objectives To evaluate the effectiveness of transcarotid artery chemotherapy for gliomas after surgery, and selection of drug, avenue of administration, and optional time for the therapy. Methods Beginning from 4 to 30 days after operation, Nimustine (ACNU, Japan) 2.5mg/kg was injected per carotid artery, once every week for three times as one course. A second course of treatment was given after an interval of 4 to 6 weeks. Results With the above regime, the effect was marked in 39 cases (18.8%), fairly effective in 44 cases (20.8%), only slightly effective in 59 cases (27.8%), no effect in 61 cases (28.8%), and failure in 5 cases (2.4%), the mean survival time was nearly 100 weeks. Conclusion Transcarotid artery chemotherapy for gliomas is helpful in prolonging survival period, with little side effects, easy to carry out, less expensive, and better accepted by the patients.

Objective To apply the Chinese version of Care Transition Measure (C-CTM) in patients with chronic diseases to assess the quality of transitional care and its influencing elements in order to provide reference for improving the quality of transitional care. Methods A total of 210 patients with chronic diseases were telephoned 2 to 4 weeks after discharge using C- CTM. Results The C- CTM score of the 210 study participants was 52.37±15.45. The general self- care preparation scored the highest which was 65.48±15.07, written plan was the lowest with a median score of 16.67. Multiple regression analysis showed that education level, hospital class and Activity of Daily Living (ADL) scores upon admission were significantly positively associated with the C- CTM scores. Conclusions The overall quality of transitional care was poor, especially in written plan. Quality of transitional care was poorer in patients with lower education level, being admitted to lower class hospitals and with lower ADL scores upon admission.

OBJECTIVE:To evaluate the content validity and interrater reliability of the modified medication discrepancy tool (MDT). METHODS:According to the structure of MDT(English edition),the terms of MDT were modified,and 5 invited ex-perts used content validity indicator to test the content validity of MDT. The interrater reliability method was adopted to test the reli-ability of MDT. The interrater reliability was performed by 2 evaluators to same 20 research objects with modified MDT. RE-SULTS:Average item-level content validity index was over 0.800,and scale-level content validity index was 0.970. The item-level interrater reliability was between 0.667 and 1.000(P<0.01). The scale-level interrater reliability was 0.840(P<0.01). CONCLU-SIONS:The modified MDT has good content validity and interrater reliability,and can be used to evaluate discharged medication discrepancies in China.

Objective To investigate the serotypes of human enterovirus B ( HEV-B) species cau-sing hand, foot and mouth disease ( HFMD) and to analyze the genetic characteristics of VP1 region in cox-sackievirus B2 ( CVB2 ) and coxsackievirus B5 ( CVB5 ) strains circulating in Anyang area during 2011 to 2015. Methods Real-time RT-PCR and semi-nested RT-PCR were performed to identify coxsackievirus A16 (CVA16), enterovirus 71 (EV71) and other serotypes of enterovirus in order to obtain the complete etiologic composition of HFMD. The numbers of HEV-B serotypes and the percentages of specimens positive for every serotype in all enterovirus-positive specimens were calculated. As CVB2 and CVB5 were the pre-dominant serotypes of HEV-B species, five pairs of primers targeting the VP1 regions of CVB2 and CVB5 were designed to obtain the complete nucleotide sequences of CVB2 and CVB5 VP1 regions. The phylogenet-ic trees were constructed based on the VP1 sequences obtained in this study and those submitted to GenBank by using MEGA7. 0 and BioEdit7. 2. The selection pressures on VP1 regions of CVB2 and CVB5 strains cir-culating in China in recent years were evaluated with the online program of DataMonkey. Results A total of 57 specimens that belonged to 14 serotypes of HEV-B species were detected in Anyang area from 2011 to 2015. The 14 serotypes of HEV-B species accounted for 56% of all serotypes of enterovirus and the speci-mens positive for HEV-B species accounted for 3. 06% of all enterovirus-positive specimens. The HFMD ca-ses caused by most of the HEV-B serotypes were sporadic cases. Small outbreaks of HFMD could also be caused by some serotypes of HEV-B such as CVB2 and CVB5. The complete sequences of VP1 region were obtained from 8 CVB2 strains and 9 CVB5 strains. The phylogenetic trees based on the VP1 sequences dem-onstrated that the CVB2 strains were classified into four genotypes ( A-D) . The mean evolutionary distances between different genotypes ranged from 0. 191 to 0. 208 and the similarities in nucleotide sequences ranged from 79. 7% to 85. 8%. The CVB5 strains were classified into 6 genotypes (A-F). The mean evolutionary distances and the similarities in nucleotide sequences between different genotypes of CVB5 strains ranged from 0. 170 to 0. 285 and 76. 0% to 86. 8%, respectively. Strains of different genotypes varied significantly in the residues on positons 157 and 263 in the VP1 region of CVB2 strains and on positions 75, 90 and 95 in the VP1 region of CVB5 strains. All of the CVB2 strains isolated in Anyang area belonged to D genotype and located intensively in one lineage. The CVB5 strains circulated in Anyang area belonged to F genotype and located in two lineages. The selection pressures on CVB2 strains of D genotype and CVB5 strains of F geno-type circulating in China in recent years were 0. 037 and 0. 036, respectively. Six positively selected amino acid sites were found in the VP1 region of CVB5 strains, but no positively selected amino acid site was found in the VP1 region of CVB2 strains. Conclusion HEV-B species was an essential component of the etiologic spectrum of HFMD in Anyang area during 2011 to 2015, of which CVB5 and CVB2 were the predominant se-rotypes. The VP1 region of CVB5 was more complex and active than that of CVB2 over the course of evolution.
