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.

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.

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.

Background Retinal development continues during the early postnatal period in mammals.Correct arrangement of layers and precise location of various cells in the retina are vital for forming normal visual function during critical period plasticity.Spectral-domain optical coherence tomography(SD-OCT)provides highquality in vivo retinal imaging and the possibility to measure retinal thickness longitudinally. Objective The present study was to investigate the changes of retinal thickness during critical period plasticity in rats. Methods In vivo consecutive scanning of retinal image was performed in 10 SPF Sprague-Dawley rats at postnatal day 14(P14),P18,P21,P24 and P42 with SD-OCT,and retinal histopathological examination was used to detect retinal morphologic changes at the same postnatal ages in 20 matched rats.The whole retinal thickness,the thickness from inner limiting membrane(ILM)to inner plexiform layer(IPL),the thickness of inner nuclear layer(INL)and the thickness from outer nuclear layer(ONL)to retinal pigment epithelium(RPE)were measured using Cirrus HD-OCT system and HMIAS-2000 Imaging System in retinal sections.The measurement parameters by Cirrus HD-OCT and those by hematoxylin-eosin staining were compared.The use of animals followed the Statement of National Institute of Health (USA). Results In vivo high-resolution images of rat retinas with SD-OCT compared well with histology,which enabled quantitative comparison of the SD-OCT and histological data during critical period plasticity in rats.From P14 to P42,the retinal thickness gradually decreased with the increase of rat ages(F=15.425,P=0.000),and so were the thickness from ILM to IPL,the thickness of INL and the thickness from ONL to RPE(F=3.973,P=0.007;F=17.529,P=0.000;F=7.038,P=0.000).The retinal thickness,thickness of INL.thickness from ONL to RPE measured by Cirrus HD-OCT were significantly correlated with those measured by retinal sections among P14,P18,P21,P24 and P42 rats(r=0.794,P=0.000;r=0.784,P=0.000;r=0.681,P=0.000). Conclusion SD-OCT is a demonstratably valuable technology to study the structure of retinas in rats.The retinal thickness is shown to reduce in thickness throughout the development of the retina during critical period plasticity due to the decrease in thickness of INL and the distance from the ONL to RPE,as illustrated by OCT scanning.
