Objective: To investigate the protective effect of shenduqing Granules on chronic renal insufficiency in rats. Methods: The rat model of chronic renal insufficiency was made by feeding 0.75% adenine forage. The blood biochemical indexes, ion concentration in serum of rat was measured and the pathological changes of rat kidney were observed. Results: Shenduqing Granules obviously increased thymus index (TI). The weight of rat kidney in the treatment group was lighter than that of the model group. The kidney histomorphological study showed that Shenduqing Granules obvionsly reduce the pathological changes. The drug crystals were also reduced. Conclusion: Shenduqing Granules has the potential protection against chronic renal insufficiency in rats.

Objective To investigate the drug resistance of bacteria clinically isolated from Yuyao people's hospital and its relationship with antibiotic consumption, in order to provide basis for rational use of antibiotics in clinic.MethodsA total of 3178 strains of bacteria were detected in our hospital from the third quarter of 2015 to the second quarter of 2016.The drug resistance of bacteria, the consumption of antibacterial agents in each quarter, and their relationships were analyzed.ResultsThe major isolated bacteria was gram-negative bacteria, among which constituent ratio of Escherichia coli, Klebsiella pneumoniae, Acinetobacter baumannii and Pseudomonas aeruginosa ranked the top 4.Gram-negative bacteria's resistance rates of several antibiotics were positively correlated with the utility rate of quinolones, and also had a different degree of positive correlation with the use of beta lactamase/inhibitor, aminoglycosides and carbapenems.Staphylococcus were the mainly gram positive bacteria, whose resistance rates to penicillin, ciprofloxacin, levofloxacin and erythromycin were positively correlated with the usage of the same type of antibiotics.ConclusionBacterial resistance rates are closely associated with the consumption of antimicrobials.Selecting antibacterial agents reasonably according to the results of drug susceptibility test is important to control the drug resistance of bacterial.

Objective To investigate the protective and therapeutic effect of chalcone ketones compound(code:L2H17,hereinafter referred to as L2)on mice infected with influenza A virus.Methods BALB/c mice were randomly divided into six groups:normal group,model group,positive drug-treated group,L2 treated groups (3 different concentrations).The mice were adapted for 72 hours,before a model was established by intranasal infection.Mice in each group were given medicine by i.g once daily for 6 days starting 24 h before virus challenge.Survival was observed daily for 14 days.The mortality,median survival time,rate of death protection and rate of prolonging life were determined to observe the therapeutic effect of chalcone(L2) against influenza virus infection.The whole lungs were taken under aseptic conditions on days 3 and 5 post-infection to calculat lung indexes and lung index inhibition.The left lung was fixed with 4% formaldehyde for pathological biopsy,the right lung was soaked in RNAstore to detect lung tissue viral load,and the double antibody sandwich ELISA method was used to detect the expression of inflammatory cytokines IL-6 and TNF-α in order to observe the therapeutic effect of L2 on viral pneumonia caused by influenza virus infection.Results Compared with the model group,the L2 80 mg/kg treatment group exhibited significant increases in median survival time(11 d),the rate of death protection (50%),and the rate of prolonging life(24.1%)but a moderate 50% decrease in mortality.In addition,the lung index decreased significantly both on d 3 and 5 after virus infection (P<0.05).The pathological results also improved significantly.The L2 80 mg/kg dose group had a significantly lower viral load of lung tissue on d 3 and 5 post-infection(P<0.05).Compared with model group,the expression of inflammatory factor IL-6 became lower to different degrees.Conclusion L2 has a protective effect on mice infected with influenza virus by reducing the degree of pathological changes of pneumonia caused by influenza viruses.

Objective To optimize the enamel electron paramagnetic resonance (EPR) spectral processing by using the EPR spectral simulation method to improve the accuracy of enamel EPR dosimetry and reduce artificial error.Methods The multi-component superimposed EPR powder spectral simulation software was developed to simulate EPR spectrum models of the background signal(BS) and the radiation- induced signal (RS) of irradiated enamel respectively.RS was extracted from the multi-component superimposed spectrum of irradiated enamel and its amplitude was calculated.The dose-response curve was then established for calculating the doses of a group of enamel samples.The result of estimated dose was compared with that calculated by traditional method.Results BS was simulated as a powder spectrum of gaussian line shape with the following spectrum parameters:g =2.00 35 and Hpp =0.65 - 1.1 mT,RS signal was also simulated as a powder spectrum but with axi-symmetric spectrum characteristics.The spectrum parameters of RS were:g(1) =2.0018,g (11) =1.996 5,Hpp =0.335 - 0.4 mT.The amplitude of RS had a linear response to radiation dose with the regression equation as y =240.74x + 76 724 ( R2 =0.9947 ).The expectation of relative error of dose estimation was 0.13.Conclusions EPR simulation method has improved somehow the accuracy and reliability of enamel EPR dose estimation.
