Objective: To study the influence of screening dementia with mini-mental state examination (MMSE) combining with delay memory test . Methods: MMSE and delay memory test are used in screening 301 residents. The diagnosis of dementia is according to the DSM-Ⅲ-R criterion. The validity and reliability were studied when the MMSE and delay memory test were used to screen dementia alone or combined. Results: When MMSE was used to screen dementia alone, the specificity, sensitivity, false positive proportion and false negative proportion were 85.40%, 52.43%, 47.56% and 14.60% respectively. When delay memory test was used to screen dementia alone, the specificity, sensitivity, false positive proportion and false negative proportion were 74.45%, 92.07%, 7.93% and 25.55% respectively. If parallel connection of MMSE and delay memory test were used to screen dementia, the specificity, sensitivity, false positive proportion and false negative proportion were 95.62%, 49.39%, 50.61% and 4.38% respectively. If MMSE was in series with delay memory test, the specificity, sensitivity, false positive proportion and false negative proportion of screening dementia were 64.23%, 95.73%, 4.27% and 35.77% respectively. Conclusion: The parallel connection of MMSE and delay memory test can elevate sensitivity of screening dementia and decrease false negative proportion, so it is important in epidemiologic investigation. MMSE in series with delay memory test will raise specificity of screening dementia and decrease false positive proportion, so it is useful for diagnosing early dementia.

Journal of Acupuncture and Tuina Science 2006;4(5):293-295
Objective: To investigate the therapeutic effect of acupuncture plus hyperbaric oxygen in treating hypoxemic infantile encephalopathy (HIE). Methods: Fifty-nine HIE children were divided into treatment (33 cases) and control (26 cases) groups. Both groups were treated by basic therapy of removing acidosis, controlling cerebral edema and convulsion, and intravenous drip of cerebrolysin or citicoline. The treatment group was treated by acupuncture plus hyperbaric oxygen and the control group was treated by hyperbaric oxygen only. Results: The total effective rate was 97.0% in the treatment group and 73.1% in the control group. Statistical analysis showed a highly significant difference (P<0.01). Conclusion: Acupuncture plus hyperbaric oxygen was better than simple hyperbaric oxygen in treating HIE. Its main manifestations were shortening the course of disease, increasing cure rate, decreasing death rate and reducing the occurrence of sequelae.HIE children should be treated as early as possible.
