Electroacupuncture （EA） at Zhongliao （BL33） can improve the symptoms of overactive bladder （OAB）, such as urinary frequency, urgency, and incontinence. However, its performance compared with other acupoints remains unclear. This study investigated the effects of EA at BL33 with deep needling on rats with OAB by detecting urodynamics in eight groups： no intervention group, d-BL33 group （deep needling at BL33）, S-BL33 group （shallow needling at BL33）, non-acupoint group （needling at the non-acupoint next to BL33）, Weizhong （BL40） group, Sanyinjiao （SP6） group, Tongtian （BL7） group, and Hegu （LI4） group. Results revealed that EA at BL33 with deep needling, BL40, and SP6 prolonged the intercontraction interval （ICI） of rats with OAB （P= 0.001, P = 0.005, P = 0.046, respectively, post-treatment vs. post-modeling）. Furthermore, the change in ICI from post-modeling in the d-BL33 group was significantly greater than those of the no intervention and other EA groups （all P 〈 0.01）. Significantly shortened vesical micturition time （VMT） and elevated maximum detrusor pressure （MdP） were also observed in the d-BL33 group （P = 0.017 and P = 0.024, respectively, post-treatment vs. post-modeling）. However, no statistically significant differences in the changes of VMT and MdP from post- modeling were observed between d-BL33 and the other EA groups. In conclusion, EA at BL33 with deep needling may inhibit acetic-acid-induced OAB more effectively.

El Nifio and Southern Oscillation （ENSO） is an interannual phenomenon involved in the tropical Pacific sea-air interactions. An asymptotic method of solving equations for the ENSO model is proposed. Based on a class of oscillator of ENSO model and by employing a simple and valid method of the variational iteration, the coupled system for a sea-air oscillator model of interdecadal climate fluctuations is studied. Firstly, by introducing a set of functionals and computing the variationals, the Lagrange multipliers are obtained. And then, the generalized variational iteration expressions are constructed. Finally, by selecting appropriate initial iteration, and from the iterations expressions, the approximations of solution for the sea-air oscillator ENSO model are solved successively. The approximate dissipative travelling wave solution of equations for corresponding ENSO model is studied. It is proved from the results that the method of the variational iteration can be used for analyzing the sea surface temperature anomaly in the equatorial Pacific of the sea-air oscillator for ENSO model.
