[Controlled study on needle-pricking therapy combined with spinal massage for treatment of ankylosing spondylitis].

Objective: To observe the therapeutic effect of needle-pricking therapy combined with spinal massage on ankylosing spondylitis and to probe into the mechanism.

Methods: Ninety-three cases who were definitely diagnosed as having ankylosing spondylitis at active stage were randomly divided into a medication group (n=46) and an observation group (n=47). The observation group were treated by needle-pricking the main points, Neck No.

[Sensory gating of patients with first-episode schizophrenia].

Objective: To investigate the characteristics of sensory gating P50 of patients with first-episode schizophrenia.

Methods: The auditory evoked potentials P50 were recorded in 66 patients (Group Sch) with first-episode schizophrenia and 92 normal controls (Group NC) by using conditioning/testing paradigm presented with auditory double click stimuli.

Results: The value of S1-P50 of Group Sch was 3 microV +/- 2 microV, significantly lower than that of Group NC (6 microV +/- 3 microV, P <0.
