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 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.

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 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.
