针刺配合药物治疗甲状腺结节的疗效观察

目的观察针刺配合药物治疗甲状腺结节的临床疗效。方法将116例甲状腺结节患者随机分为治疗组和对照组,每组58例。对照组采用口服加味柴胡桂枝汤配合左甲状腺素钠片治疗,治疗组在对照组基础上采用针刺治疗。观察两组治疗前后各项甲状腺功能指标[游离三碘甲状腺原氨酸(FT3)、游离四碘甲状腺原氨酸(FT4)、促甲状腺激素(TSH)]、甲状腺结节情况(大小、数量及体积)及中医证候评分的变化情况,并比较两组临床疗效。结果两组治疗后TSH水平、甲状腺结节情况及中医证候评分与同组治疗前比较,差异均具有统计学意义(P<0.05)。治疗组治疗后TSH水平、甲状腺结节情况及中医证候评分与对照组比较,差异均具有统计学意义(P<0.05)。治疗组总有效率为93.1%,对照组为79.3%,两组比较差异具有统计学意义(P<0.05)。结论针刺配合药物治疗甲状腺结节疗效确切,能改善患者甲状腺结节的直径、数量、体积。

Multisymplectic Geometry for the Seismic Wave Equation

The multisymplectic geometry for the seismic wave equation is presented in this paper.The local energy conservation law,the local momentum evolution equations,and the multisymplectic form are derived directly from the variational principle.Based on the covariant Legendre transform,the multisymplectic Hamiltonian formulation is developed.Multisymplectic discretization and numerical experiments are also explored.
