[Rasch analysis on stroke-specific quality of life (SS-QOL) scale of acupuncture intervention on stroke].

OBJECTIVE: To optimize the evaluation level of active motor threshold and the functional domain of upper limbs of stroke-specific quality of life (SS-QOL) scale with Rasch analysis. METHODS: Sixty patients with acute ischemic stroke that were in accord with research criterid were randomly divided into a test group (30 cases) and a control group (30 cases). Acupuncture treatment and routine western medicine were applied on the test group, and single treatment of routine western medicine was applied on the control group. Selected acupoints were MS 5, Fengchi (GB 20), Hegu (LI 4), etc. Active motor threshold and the functional domain of upper limbs of SS-QOL were self-tested by patients after one treating course. The characteristics of the above mentioned items were tested with Rasch model. RESULTS: The statistical result on fitness of active motor threshold and the functional domain of upper limbs of SS-QOL showed that every reference of samples and items wosin accord with the Rasch model and has well inner reliability and validity. The Infit and Outfit MnSq values of active motor threshold and the functional domain of upper limbs of SS-QOL are basically between 0.5 and 1.5. CONCLUSION: The application of Rasch analysis on the assessment of patient reported outcome (PRO) has optimized the PRO scale (the activity and upper limb function domain of SS-QOL scale) and enhanced evaluation level of active motor threshold and the functional domain of upper limbs of SS-QOL scale.

Study on canceration law of gastric mucosal dysplasia based on syndromes of Chinese medicine.

OBJECTIVE: To study the syndrome evolution law of Chinese medicine (CM) in the patients with gastric mucosal dysplasia. METHODS: Three hundred and twenty four gastric mucosal dysplasia patients with deficiency and excess correlation syndromes were enrolled by a multi-center collaboration for two years' clinical follow-up to detect the levels of tumor supplied group of factors (TSGF) and carcino-embryonic antigen (CEA). RESULTS: Among the 324 cases, 29 cases turned cancer in the two years, and the canceration rate was 9.0%. The three syndromes with higher canceration rate were the damp-heat accumulating Wei syndrome concurring or combining with asthenia-cold in Pi and Wei syndrome for 16.7%; stagnation in Wei collaterals syndrome concurring or combining with asthenia of both qi and yin syndrome for 13.2%; stagnation of Gan and Wei qi syndrome concurring or combining with asthenia-cold in Pi and Wei syndrome for 8.0%, respectively. Among the three syndromes, the highest level of TSGF occurred in the former two syndromes. In the half year before carcinogenesis, the syndromes of the patients took on deficiency and excess concurrent syndromes, and the deficiency syndromes involving the qi and blood deficiency syndrome and the Shen deficiency syndrome accounting for 48.0%. CONCLUSIONS: Gastric mucosal dyspalsia canceration syndromes took on the polymorphism of excess and deficiency concurrent syndromes and had the characteristics of deficiency syndromes involving qi and blood deficiency syndrome and Shen-yin-yang deficiency syndrome.
