In this paper, the new carbon nanotube modified glassy carbon electrode (F-CNTs/GCE) was prepared to establish a new method for studying the molecular interaction mechanism between baicalin metal complexes (BMC) and bovine serum album (BSA), and the principle of this method was discussed deeply. Under the physiological condition, the thermodynamics and kinetics properties of interaction between BMC and BSA were studied by cyclic voltammetry (CV) to inference their molecular effective mechanism. The results show that the presence of F-CNTs can accelerate the electron transfer, and better response signal was showed in the BMC/BMC-BSA system. The detection of interaction of BMC-BSA used new method show that BMC-BSA generates stable thermodynamically non-covalent compounds, and the obtained average binding sites of BMC-BSA were 1.7; the number of electron transfer in BMC/BMC-BSA reaction process was 2, and non electroactive supramolecular compounds of BMC-BSA were generated by this interacting reaction. The relevant research work provides a new way to study the molecular mechanism for the interaction of drugs with protein, and with a certain reference value for discussion on the non covalent interactions.

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.

Objective To discuss the optimalselection of the puncture path in performing CT-guided pericardial drainage,and to evaluate its clinical feasibility and safety.Methods A total of 114 patients with pericardial effusion,who were admitted to authors' hospital during the period from May 2013 to March 2016,were enrolledin this study.The appropriate body position and suitable needle-puncturing route were selected,and CT-guided pericardial drainage with Seldinger'stechnique was performed.Results Successful puncturing and catheter drainage was obtained in all 114 patients,no any serious complication occurred.The time used for manipulation was 18-30 min.Conclusion The use of right puncture path is of great importance for the performance of CT-guided pericardial drainage for pericardial effusion,this technique is highly feasible and safe for relieving the clinical symptoms of pericardial tamponade.

In this study, prescriptions were collected to establish a database based on the traditional Chinese medicine inheritance support system (TCMISS). Such data-mining methods as software's statistical statement module, data analysis module and apriori algorithm were used to analyze the frequency of single drug, the frequency of drug combination, the association rules and the core drug combinations of ostreae concha-containing prescriptions. The results showed that Ostreae Concha-containing prescriptions were frequently used to treat insomnia, vertigo, stomach-ache and other syndromes. The frequently used drugs included Ossis Mastodi Fossilia, Parched Ziziphi Spinosae Semen, Polygoni Multiflori Caulis, Salviae Miltiorrhizae Radix and Paeoniae Rubra Radix. The frequently used drug combinations included "Ostreae Concha and Ossis Mastodi Fossilia", "Ostreae Concha and Parched Ziziphi Spinosae Semen", and "Ostreae Concha and Polygoni Multiflori Caulis". The drug association rules with the confidence coefficient of more than 0. 95 included "Ossis Mastodi Fossilia-->Ostreae Concha", "Cocos Poria-Ossis Mastodi Fossilia-Ostreae Concha", "Ossis Mastodi Fossilia-Parched Ziziphi Spinosae Semen-->Ostreae Concha", and "Salviae Miltiorrhizae Radix-Ossis Mastodi Fossilia--Ostreae Concha".

Analyzed the prescriptions for phlegm retention syndrome that built by Ma Peizhi by the association rules and clustering algorithm, the frequency of drug usage and the relationship between drugs could be get. And from that we could conclude the experiences for phlegm retention syndrome of Ma Peizhi of menghe medical genre. The results of the analysis were that 18 core combinations were dig out, such as Citri Exocarpium Rubrum-Eriobotryae Folium-Citri Reticulatae Pericarpium. And there were 9 new prescriptions were found out such as Aurantii Fructus-Citri Exocarpium Rubium-Eriobotryae Folium-Citri Reticulatae Pericarpium. The results of the analysis were proved that Ma Peizhi of Menghe Medical Genre was good at curing phlegm retention syndrome by using the traditional Chinese medicine of mild and light, such as the medicines of mild tonification, and clearing damp and promoting diuresis.
