OBJECTIVE： There are no convenient techniques to evaluate the degree of facial nerve injury during a course of acupuncture treatment for Bell＇s palsy. Our previous studies found that observing the electrical response of specific facial muscles provided reasonable correlation with the prognosis of electroacupuncture treatment. Hence, we used the new method to evaluate the degree of facial nerve injury in patients with Bell＇s palsy in comparison with the House-Brackmann scale. The relationship between therapeutic effects and prognosis was analyzed to explore an objective method for evaluating Bell＇s palsy. METHODS： The facial nerve function of 68 patients with Bell＇s palsy was assessed with both electrical response grading and the House-Brackmann scale before treatment. Then differences in evaluation results of the two methods were compared. All enrolled patients received electroacupuncture treatment with disperse-dense wave at 1/100 Hz for 4 weeks. After treatment, correlation analysis was conducted to find the relationship between electrical response and therapeutic effects or prognosis. RESULTS： Checking consistency between electrical response grading and House-Brackmann scale： Kappa value 0.028 （P = 0.578）. Correlation analysis： the two methods were correlated with the prognosis, and electrical response grading （rER = 0.789） was better than the House-Brackmann scale （rHB = 0.423）. CONCLUSION： electrical response grading is superior to the House-Brackmann scale in efficacy and reliability, and can conveniently assess the degree of facial nerve injury. The House-Brackmann scale is suitable for the patients with mild facial nerve injury, but its evaluation quality for severe facial nerve injury is poor.

electrical response of Silanization of Rubber Mixtures

There are a number of experimental methods aimed at the investigation of structural transformations. These methods differ from each other by a spectrum of quantitative indicators and their application is limited by the nature of investigated structures and processes. In a sense, it is also possible to consider the silanization of rubber mixtures as a structural transformation. Experimental observation of transformations of disordered rubber mixtures type structures can be quite difficult. The contribution deals with the theoretical principles of experimental methodology oriented on the investigation of silanization of rubber mixtures. We analyze the electrical response of rubber mixtures silanization. Our attention is focused on the modeling of a possible electrical response of a chemical reaction in a system consisting of several components. The results of the model are compared with experimental data measured during the silanization reaction in rubber mixtures.

electrical responses and Stable Behavior of Polyaniline-polyurethane Concave Lens Array Film in Electrolyte

引用

Chemical Research in Chinese Universities 2015年第4期31卷 680-684页

作者： MENG Xiaomin YANG Xiaohang WANG Hongjuan JIA Ruokun College of Chemical Engineering Northeast Dianli University Jilin 132012 P. R. China

We present a synthetic methodology of polyaniline-polyurethane（PANI-PU） copolymer using interfacial in situ polymerization. PANI-PU copolymer was obtained through in situ polymerization of aniline precursor and the concave lens array film was molded by water drops. The fabrication of unique structured film was obtained through a solvent evaporation self-formed system. The detailed nanostructures of the film were illustrated by scanning electron microscopy（SEM） images, which showed homogeneous structure in a close-packed hexagonal arrangement. The di- mension of well-structured hexagon ranged from 10.8 ~tm to 12.9 lxm. Sensitive electrical responses of the concave lens array film resulted in the changes of swelling/shrinkage ratio in electrolyte under various conditions. Dimen- sional control of the film was achieved via adjusting a series of parameters including time, voltage, concentration and type of electrolyte. The electrical responses resulted rearranged molecular chain caused by redox reaction via powered PANI. Most importantly, the film maintained its response characteristics after 16 cycles. The high stability of film could be directly attributed to PU doping, which could help the PANI enhancing the mechanical strength and chemical solubility in solution.
