A method was developed for the determination of 39 polybrominated diphenyl ethers(PBDEs) from mono- to hepta-brominated in coastal sediment by gas chromatography/mass spectrometry. The sample was extracted with a solution of dichloromethane: n-hexane( 1:1,V/V) ,followed by ultrasonic extraction for 60 min at 25℃. The clean-up step was optimized using silica gel and alumina. The detection limit of the method was in the range of 0.003 - 0.10μg/kg. The results indicate that the average recovery of the internal standard was from 66.2% to 118. 6%. The relative standard deviation RSD( % ) was from 0. 8 % to 18. 2%. The method for the detection of 39 PBDE congeners in coastal sediment was sensitive,high reproducible with satisfactory recoveries.

Psychological disorder has a high morbidity rate among patients with cardiovascular disease. Patients with cardiovascular disease associated with depression, especially post myocardial infarction and acute coronary syndromes associated with psychological disorder, have not only a poor prognosis, but also a high mortality . Therefore, comprehensive and perfect intervention is extremely important for patients with cardiovascular disease associated with psychological disorder. The intervention for such kind patients needs an integrated disease management. It needs to consolidate the treatment of body's disease to strengthen second-level prevention of heart disease, and pay attention to the intervention for psychological disorder as well.This paper aims to provide reference for reducing the negative effects of psychological illness in patients with cardiovascular disease during clinical treatment process, and make prospects about the significance of double heart medical model, through summarizing the interaction effects of psychological factors on patients with coronary heart disease, the significance ofdouble heartnursing mode and the specific nursing measures.

Objective To observe and compare the clinical effect of treating benign primary blepharospasm(BPB)with acupuncture and injection of type A botulinum toxin. Methods Between January 2012 to July 2013, 80 cases of BPB patients in ophthalmology of Tongren hospital were randomly recruited into a acupuncture group and a control group, with 40 cases in either group. The acupuncture group was treated with acupuncture on points of strengthening spleen and distributing liver and the control group was treated by type A botulinum toxin injection around effected eyes. Then effective rate, visual impairment of quality of life scale and self-rating depressive scale were tested after the treatments. Results The total effective rate of acupuncture was 95%, which was better than injection with type A botulinum toxin, with statistical difference(P<0.01). There was no statistical difference in visual impairment of quality of life scale in both groups after the treatment compared with before treatment(P>0.05). Visual impairment score was (121.88±30.16) and (121.00±28.72) in the acupuncture group and control group respectively before the treatment, However, acupuncture group(70.00±22.88)reduced less than control group(95.25±28.39)after the treatment, and there was statistical difference(P<0.01). There was no statistical difference in self-rating depressive scale in groups before treatments(P>0.05), (acupuncture group was(15.90±7.99) and control group was(15.75±6.26). However, acupuncture group(10.40±4.95)reduced less than control group(13.38±6.32)after the treatment, and there was statistical difference(P<0.01). Conclusion It proved that the therapy of acupuncture with strengthening spleen and distributing liver method for benign primary blepharospasm has a better result than injection with type A Botulinum toxin. Moreover, acupuncture can promote optical function and prevent depression for BPB patients.
