METHODS: A total of 60 diarrhea patients with deficiency and cold syndrome were randomly divided into observation group and control group, with 30 cases in each group. The control group was treated with conventional western medicine. The observation group was given the treatment of Zhenren Yangzang Decoction combined with modified Shenling Baizhu Powder on the basis of the same treatment for 4 weeks. The clinical symptoms, fecal flora and immunoglobulin content of the 2 groups were observed and the clinical efficacy was evaluated. RESULTS: After treatment, the symptoms scores of fecal diarrhea, aversion to cold, cold limbs, loss of appetite, cold and painful waist and knee, abdominal fullness, abdominal distension and abdominal pain, and intestinal bacilli contents were significantly decreased(P < 0.05). The contents of lactobacillus, bifidus bacilli, IgG, IgM and IgA were significantly increased(P < 0.05), and the improvement of the above indexes in the observation group was significantly better than that in the control group(P < 0.05). The total effective rate after treatment in the observation group was 93.3%, which was significantly higher than 73.3% of the control group(P < 0.05). CONCLUSION: The treatment of diarrhea patients with deficiency and cold syndrome with Zhenren Yangzang Decoction and modified Shenling Baizhu Powder can effectively improve the intestinal micro-ecological environment, improve the immune function of patients and promote the rapid recovery of patients.展开更多

Through the uEAC mathematical model, the resistance properties of the conductive sheet, several feedback uEAC models, and a more flexible uEAC cell structure with a multi-level hierarchy are discussed. Futhermore, for the dynamic uEAC array with a linear Lukasiewicz function, a nonlinear differential equation description is presented, and then a sufficient global asymptotic stability condition is derived by utilizing a Lyapunov function and a Lipchitz function. Finally, comparative simulations for a cam servo mechanism system are conducted to verify the capability of the uEAC array as an adaptive controller.展开更多

Based on the modified couple stress theory and the principle of minimum potential energy, the governing equations and boundary conditions for a micro-structure-dependent beam theory are derived. The present beam theory incorporates different kinds of higher-order shear assumptions as well as the two familiar beam theories, namely, the Euler-Bernoulli and Timoshenko beam theories. A numerical solu- tion procedure, based on a generalized differential quadrature method （GDQM）, is used to calculate the results of the bi-directional FG beams. The effects of the two exponential FG indexes, the higher-order shear deformations, the length scale parameter, the geomet- ric dimensions, and the different boundary conditions on the critical buckling loads are studied in detail, by assuming that Young＇s modulus obeys an exponential distribution function in both length and thickness directions. To reach the desired critical buckling load, the appropriate exponential FG indexes and geometric shape of micro-beams can be designed according to the proposed theory.展开更多
