[Efficacy and safety of ropinirole in the treatment of Parkinson's disease: a multi-center, randomized, double-blind and bromocriptine-controlled trial].

Objective: To explore the efficacy and safety of ropinirole in the treatment of Parkinson's disease.

Methods: From November 2005 to April 2007, a total of 221 subjects from 7 hospitals of Beijing, Lanzhou and Wuhan participated in a 12-week multi-center, randomized, bromocriptine-controlled, double-blind, double-dummy and parallel-group trial. The efficacy of ropinirole was assessed with the unified Parkinson's disease rating scale (UPDRS) score, "off" time according to the patient's diary and the overall evolution of clinical efficacy.

[Significance of sympathetic skin response in diagnosis diabetic small fiber neuropathy].

Objective: To investigate the significance of sympathetic skin response (SSR) in the diagnosis of diabetic small fiber neuropathy.

Methods: 38 diabetic patients with paraesthesia and 30 healthy controls underwent SSR test on the 4 limbs. The latencies of the initiation and waves N and P of SSR were analyzed.

Value of sympathetic skin response test in the early diagnosis of diabetic neuropathy.

Background: Diabetic neuropathy is common in diabetes mellitus. The early stage of diabetic neuropathy is often symptomless and difficult to be treated. The aim of this study was to assess the correlation between the results of the sympathetic skin response (SSR) test and the development of diabetic neuropathy, and explore the use of SSR as an objective basis for the early diagnosis of diabetic neuropathy.

Pathogenesis and electrodiagnosis of cubital tunnel syndrome.

Background: Cubital tunnel syndrome is a well-recognized clinical condition and is the second most common peripheral compression neuropathy. This study was designed to investigate the causes of cubital tunnel syndrome by surgical means and to assess the clinical value of the neurophysiological diagnosis of cubital tunnel syndrome.

Methods: Twenty-one patients (involving a total of 22 limbs from 16 men and 5 women, aged 22 to 63, with a mean age of 49 years) with clinical symptoms and signs indicating a problem with their ulnar nerve underwent motor conduction velocity examinations at different sites along the ulnar nerve and examinations of sensory conduction velocity in the hand, before undergoing anterior transposition of the ulnar nerve.
