Objective To investigate the influence of nursing intervention on perioperative psychological status and treatment compliance of patients undergoing breast augmentation. Methods 82 patients were investigated with self-rating anxiety scale (SAS), self-rating depression scale (SDS), self-designed mental activity questionnaire on patients with breast augmentation. And they were divided into the intervention group(42 patients) and the control group(40 patients) randomly. The control group was given routine treatment and nursing. The intervention group received systematic nursing intervention such as psychological needs,confidentiality, the relevant specialist knowledge and explanation and prevention o complications besides routine treatment and nursing care. The perioperative psychological status and treatment efficacy were compared between the two groups. Results The worrying degree about operation - related problems was lower in the intervention group compared with that of the control group, but SAS and SDS score showed no significant difference one day before operation between the two groups. SAS and SDS score of the intervention group were improved before discharge compared with those before operation and were also better than those of the control group. Conclusions Patients undergoing breast augmentation surgery subject to a variety of perioperative psychological barriers, systematic nursing intervention can significantly improve the psychological state and treatment compliance, make them to acquire the unification of perfect body shape and psychology with best physical and mental status during perioperative stage.

Objective To study the topical application of Tuhuai decoction and its disassembled prescriptions on skin function of mice with epidermal hyperplasia, and to provide a theoretical basis for the treatment of psoriasis. Methods According to the Denda method, skin barrier function in mice was destructed with tape, to produce epidermal hyperplasia model. Tuhuai decoction and its disassembled prescriptions with different concentrations of water and alcohol extracts were external applied on the mice. Since the beginning of the treatment, loss of skin moisture of both sides the trunk was detected with Multi-functional instrument at every day before using the medicine. Results Tuhuai decoction had function of reducing the amount of water loss of skin. The disassembled prescriptions, such as Angelica group, safflower group, Danshen root group, and water and ethanol extracts of Prtmella group can reduce the amount of water loss of skin effect. Conclusion Water and ethanol extracts of Tuhuai decoction has the functions of reducing water loss of skin and resisting hyperplasia,suitable for treating psoriasis by external application, setting a foundation for clinical treatment of psoriasis.

A method for residual determination of 5 pyrethroid pesticides in Anoectochilus roxburghii by cloud point extraction-back extraction-GC-MS was established. PEG 6000 was used as extraction agent and isooctane was used for back-extractant. The con- tent was calculated by external standard method. The linear range was from 15 to 2 000 μg x kg(-1) with the good correlation coefficients (0.955-0.999). The recoveries at spiked concentrations of 50-500 μg x kg(-1) ranged from 85.12% to 101.6%. The limit of detection and quantification of 5 pyrethroid pesticides were in the range of 0.63-3.10 μg x kg(-1) and 2.10-10.31 μg x kg(-1), respectively. The proposed method can be applied to the determination of pyrethroid pesticides residues in A. roxburghii.
