Objective To investigate the prevalence of fatigue in AS and its relationship with other clinical and functional parameters used for the evaluation of disease activity. Methods The fatigue was assessed in 73 patients with active AS using a single-item fatigue question of BASDAI. The correlation between fatigue and the clinical parameters of disease including the Bath AS disease activity index(BASDAI), Bath AS functional index (BASFI), Bath AS metrology index(BASMI), night pain, spinal inflammation, patient's global assessment(PGA) and enthesis index(EI) were determined. Results A total of 73 patients with ankylosing spondylitis were recruited. The prevalence of fatigue was 90.4% and the fatigue score of 68.5% patients was higher than 5. After controlled for the possible confounding factors such as age, gender, age and disease duration, it was found that fatigue was highly correlated with disease activity, pain and functional disability, BASMI,physical health and mental health. Conclusion Fatigue is an important symptom in AS. Fatigue can be measured with a single-item fatigue question of BASDAI.

OBJECTIVE: To compare the acute toxicity of common injection and sustained-release preparation of norcantharidin for mice so as to identify the attenuation of the sustained-release preparation of norcantharidin. METHODS: The poloxamer 407 was used as a sustained-release vehicle for topical administration of norcantharidin, and the acute toxicity of mice treated with common injection and sustained-release preparation of norcantharidin was observed. The median lethal dose (LD(50)) was calculated by Bliss software. RESULTS: The symptoms of mice were similar between the two groups, but the appearance of symptoms in norcantharidin/poloxamer 407 group was 4 hours later than that in norcantharidin group. The LD(50) of norcantharidin administered through vein injection was 12.6 mg/kg. The LD(50) of norcantharidin/poloxamer 407 administered through intraperitoneal injection, intrahepatic injection and intramuscular injection were 19.9, 19.1 and 20.9 mg/kg, respectively, and the LD(50) of the common preparation were 13.0, 13.1 and 15.1 mg/kg, respectively. CONCLUSION: The norcantharidin/poloxamer 407 is less toxic than the equivalent dose of norcantharidin, mainly because norcantharidin/poloxamer 407 may release norcantharidin sustainedly, thus reducing norcantharidin concentration in blood.
