[Prognostic factors of myasthenic crisis after extended thymectomy in patients with generalized myasthenia gravis].
To investigate the prognostic factors of myasthenic crisis after extended thymectomy in patients with generalized myasthenia gravis (MG). ⋯ Preoperative bulbar symptoms, history of preoperative myasthenic crisis, history of preoperative infection, and large preoperative dose of, pyridostigmine are all independent influencing factors of postoperative myasthenic crisis. Ample preoperative care may prevent postoperative myasthenic crisis in the patients with such factors.

[Effects of transcranial magnetic stimulation on recovery of neural functions and changes of synaptic interface and dendritic structure in the contralateral brain area after cerebral infarction: experiment with rats].
To evaluate the effects of transcranial magnetic stimulation (TMS) on the brain plasticity and its role in functional outcome in cerebral infarction. ⋯ TMS promotes the improvement of neural functions of the rats with cerebral ischemia by the potential mechanism that TMS strengthen the compensatory roles of the synaptic interface and dendritic structure in the undamaged sensorimotor cortex area and increase synaptic plasticity.

[Effects of Ginkgo biloba extract against excitotoxicity induced by NMDA receptors and mechanism thereof].
To observe the effects of Ginkgo biloba extract (GBE) on N-methyl-D-aspartate (NMDA) excitotoxicity and focal cerebral ischemia, and further explore the neuroprotective mechanisms of GBE. ⋯ GBE pretreatment protects the neurons from excitotoxicity induced by over-activated NMDA receptor and focal cerebral ischemia, which can be explained by the mild blocking effect of GBE on NMDA receptor with low affinity, comparing with MK-801, and GBE is expected to interfere in excitotoxicity in clinic without neurotoxic behaviors.

Randomized Controlled Trial Multicenter Study[A comparison of T3 sympathectomy versus T4 sympathectomy in the treatment of primary palmer hyperhidrosis].
To evaluate the effect and side effect of T(3) versus T(4) sympathectomy in the surgical management of primary palmar hyperhidrosis through prospective multi-center randomized controlled trial. ⋯ The procedure of T(3) or T(4) sympathectomy, both transecting the sympathetic chain in one single position in relatively lower segment, are comparatively effective in the treatment of primary palmar hyperhidrosis, but T(4) sympathectomy shows less side effect.
