ObjectiveTo evaluate the clinical efficiency of 0.1％ tacrolimus ointment combined with paroxetine in patients with neurodermatitis associated with insomnia.MethodsTotally,74 patients suffering from neurodermatitis and insomnia were consecutively enrolled in this study,and randomly assigned into the combination group and control group according to their number(odd or even).Both groups were given topical 0.1％ tacrolimus ointment twice a day,and the combination group was additionally given oral paroxetine 10 mg once a day,for 8 weeks.The outcome parameters included main symptoms of neurodermatitis and Pittsburgh sleep quality index(PSQI) score.ResultsNo significant difference was observed in the cure rate (54.3％(19/35) vs.53.1％ (17/32),P＞ 0.05) or response rate (82.9％ (29/35) vs.81.3％ (26/32),P＞ 0.05),between the combination group and control group.PSQI score was significantly lower in the combination group than in the control group after 8 weeks of treatment(P ＜ 0.05).ConclusionsThe 0.1％ tacrolimus ointment can be used to treat neurodermatitis safely.Antianxiety treatment can reduce the recurrence of neurodermatitis associated with insomnia,and improve the quality of sleep in patients.

OBJECTIVE:To determine the contents of Icariin,Psoralen and Isopsoralen in Yishenling granule by HPLC. METHODS: The chromatographic separation was performed on Phenomenex luna C18 column (250 mm?4.6 mm, 5?m) with mobile phase consisted of acetonitrile-0.1% acetic acid solution (gradient elution) at a flow rate of 1.0 mL?min-1.The UV detection wavelength was set at 310 nm, and the column temperature was 20 ℃. RESULTS: Icariin,Psoralen and Isopsoralen in Yishenling granules were well-separated with good linearity within their respective concentration range. And the average recoveries for the three constituents were all within 99%～101% with RSD all less than 1.20%. CONCLUSION: The method is simple, feasible and reproducible, and it can be used for the quality control of Yishenling granule.

A PCR assay used for detection and quantification of Neotyphodium lolii in tissues of the grass Lolium perenne L. was developed. Compared with the Microscopic analysis of stained tissues, this method was more accurate. For quantitative applications, real time PCR was used to quantify Neotyphodium lolii in Lolium perenne L.. The results showed that there were some variations between different individuals, but no variance existed between different tillers from the same plant. Thus it can be concluded that fungal content in the plant is not only associated with species/variety specific, but also with the genotype of the host plant as well.

Objective To investigate the changes in hydrogen sulfide(H_2S) level in plasma and myocardial tissues of doxorubicin-induced heart failure rats,and to study the role of H_2S in the development of doxorubicin-induced heart failure.Methods Male Wistar rats were randomly divided into 2 groups as follows:the doxorubicin group(n=12),in which 2.5 mg/kg of doxorubicin was injected intraperitoneal once a week for 10 weeks(total dose of 25 mg/kg);the control group(n=9),in which an(equivalent) volume of physiological saline was administered weekly for a total of 10 weeks.The observation of behavior was taken at the same time.Hemodynamic and echocardiographic measurements were obtained 10 weeks after treatment.Meanwhile,H_2S concentrations in serum and myocardial tissues were evaluated by modified sulfide electrode method.The changes of H_2S level between 2 groups were analyzed.Results The rats treated with doxorubicin showed inanimate behavior,decrease of the body temperature,activities and food intake,faster breathing,significant loss of weight,the cumulative mortality was 33%.Left ventricular systolic pressure(LVSP),difference of left ventricular pressure[△LVP=LVSP-left ventricular diastolic pressure(LVDP)] and left ventricular peak rate of contraction(+LV dp/dtmax),left ventricular peak rate of relaxation(-LV dp/dtmax)were significantly reduced in the group of doxorubicin rats(P

OBJECTIVEThis study is performed to investigate the cell topographies and biomechanical properties of two different types of temporomandibular joint (TMJ) discs from goats by using JPK Nano Wizard 3 biological atomic force microscopy (AFM). This process provides a guideline for selecting seed cells for TMJ disc tissue engineering.

METHODSTMJ disc cells from primary goats were cultured by monolayer culture method. AFM was used to contact scan the topographies of the two types of TMJ disc cells under physiological environment. Approximately 20 chondrocyte-like and fibroblast-like cells were selected randomly to plot the force-versus-distance curves of the cytoplasm and nucleus. Young's modulus and adhesion were analyzed by JPK Data Processing.

RESULTSThe triangle-shapednucleus of the chondrocyte-like cell occupied a large portion of the cell. Cytoskeleton was arranged dendritically on the surface. Pseudopodia were extended from cell edges. The spindle-shaped nucleus of the fibroblast-like cell occupied a significantly larger region compared with the cytoplasmic region. Cytoskeleton was arranged regularly. Cell edges were smooth with less pseudopodia extended. No difference was found in the surface roughness between the two types of cells. According to the force-versus-distance curves, the Young's moduli of the two types of cells were not statistically different (P>0.05), but differences were found in the cytoplasmic regions (P=0.047). No statistical difference was found in the adhesions between the two types of cells (P>0.05).

CONCLUSIONThe AFM topography and curves were compared and analyzed. The two types of TMJ disc cells exhibited significantly different topographies, but only slight difference in their mechanical abilities.
