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 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.

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

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 evaluate the value and the expression of Axl receptor tyrosine kinase (AxlTK) in renal pathology of lupus nephritis (LN) patients. Methods The expression of AxlTK were detected in 29 LN and 10 primary nephritic syndrome (NS) patients using immunohistochemistry in renal tissue. The correlations between the levels of AxlTK on glomeruli and clinical manifestations, laboratory parameters, disease activity, and renal pathology in LN patients were investigated. T test and single factor analysis of variance were used tp compare between groups, and Pearson or Spearman test was used for correlation analysis. Results AxlTK was extensively expressed on surface of mesangial cells, endothelial cells in glomeruli. There was more expression of AxlTK on mesangial cells in LN patients [(7.0 ±2.2)×10-2] than that in primary NS patients [(3.1 ±1.2) ×10-2] (t=5.382, P<0.01). The expression of AxlTK in the glomeruli of LN patients with oral ulcers is higher than that in patients without of ulcers (t=2.259, P=0.032), and it was positively correlated with the anti-nucleosome antibody (AnuA) level in patients (r=0.488, P=0.017). The expression of AxlTK on glomeruli were higher in class Ⅳ and classⅢ of LN patients than that of class Ⅴ, but there was no statistically significant difference between them (P>0.05). Conclusion The expression of Axl TK in glomerular is significantly increased in glomeruli in LN patients. The expression level of AxlTK on glomeruli is correlated with the occurrence of oral ulcers and AnuA. The level of AxlTK expression is related to pathological categories of kidney in LN patients. The results of this study suggest that AxlTK might participate in the pathogenesis of LN.

The relationship between 5-HT receptor and a-adrenoceptor was investigated in rat medullary slice preparations. In 57 nucleus tractus solitarii (NTS) neurons, 47 (82.5%) responded to both serotonin (5-HT) and norepinephrine (NE). After synapse transmission was blocked by perfusion of artificial cerebrospinal fluid (ACSF) with low calcium and high magnesium, 5 in 8 neurons were still sensitive to both 5-HT and NE. On the other hand, 3 in 5 neurons responding only to 5-HT or NA were sensitive to both 5-HT and NE after the synapse transmission blockage. In some neurons which exhibited excitatory or inhibitory responses to 5-HT or NE alone, the responses were inversed when perfused with 5-HT and NE in combination. These results suggest that there may exist an inhibitory interaction between 5-HT receptors and a-adrenoceptors in NTS and that most 5-NT and a-adrenoceptors coexist in the same NTS neurons.

This article described the application of the phantom system in the experiment teaching of Endodontics.Through the process of teaching,we realized that the way of simulation in the experiment teaching not only can enhance the enthusiasm of students,but also can consolidate the basis of theoretical knowledge and improve the clinical skills of students.The system has become the necessary equipment and means in experimental teaching of modern stomatology.It is worth further promotion and application in dental teaching.
