[The sampling survey of denture restoration situation and its influence factors of the elders in Shanghai].

PURPOSE: The prosthetic status and associated factors of the elders in Shanghai were evaluated to provide references for the government to issue related policies. METHODS: The multi-stage stratified and isometric random sampling was used.The information of tooth loss and prosthodontic restoration was collected by oral examination in 788 elder residents aged between 65 to 74 years in Shanghai, and 325 subjects was randomly drawn from the given group to collect the information concerning socioeconomic factors and life health situation by means of interviewer administered questionnaire. A Logistic regression model(Stata.7.0) was used to analyze the related factors that have effects on whether or not those elders would choose to do the restoration. RESULTS: The restoration rate of the patient was 61.73%. The restoration rate of the patients with the defect of dentition was significantly lower than that of the edentulous(P<0.01).The constituent ratio of the denture restoration with fixed denture, the removable denture, the fixed denture and removable denture, the full denture, the informal fixed bridge was 21.94%, 41.58%, 5.87%, 20.92%, 9.69%, respectively. The ratio of full denture, fixed denture and informal fixed bridge of the suburb elders was significantly higher than that of the urban ones(P<0.01). Logistic regression analysis revealed that the position of teeth defect, the gender and the number of missing teeth were significant predictors of denture or non-denture wearers. CONCLUSIONS: Ratio of denture wearers is low in the older individuals with missing teeth in Shanghai. It is suggested that the government should take effective efforts to strengthen the people's oral health consciousness so that the elder patients could restore their lost teeth in time and more effectively.

[The sampling survey of teeth defect and denture restoration among 1579 middle aged and elder people in Shanghai].

PURPOSE: To investigate the condition of teeth defect and denture restoration among the middle aged and elder people in Shanghai and to analyse the variation tendency so as to provide relevant policy basis for the government. METHODS: Multistage stratification isasteric random sample was used to acquire the teeth defect and denture restoration information among 791 people from 35 to 44 and 788 people from 65 to 74 years old, respectively. SPSS13.0 software package was used for data analysis. RESULTS: The teeth defect rate of the middle aged and elder people in Shanghai was 21.0% and 81.0%, respectively. The mean permanent teeth number was 28.9 and 19.5. The edentulous rate of the elder people was 10.8%. The defect rate was highest in the molar area, and lowest in the canine agra. The denture restoration rate of the middle aged and elder people was 59.6% and 61.7%, respectively. The rate of the removable denture restoration was higher than that of the fixed denture. The rate of full denture, fixed denture and informal fixed bridge restoration in the suburb area was higher than that in the urban area(P<0.01). CONCLUSIONS: The condition of teeth defect and denture restoration among middle aged and elder people in Shanghai is still unsatisfactory even though it has been getting better in the last decade. It is suggested that the government take efforts to lessen the teeth defect by control of caries and periodontal disease, and to improve the restoration level of the middle aged and elder people.

[Clinical investigation on characteristics of traditional Chinese medical syndrome of hepatocirrhosis].

OBJECTIVE: To explore the characteristics of traditional Chinese medical syndrome (TCM syndrome) of hepatocirrhosis. METHODS: Clinical information from the four diagnosis methods of traditional Chinese medicine (TCM) and related laboratorial indexes were systematically collected from 223 hepatocirrhosis cases, and the multi-statistical methods including systematic cluster analysis, principal component analysis, stepwise discrimination and variance analysis were made with the software SAS 6.11. RESULTS: Multi-analysis showed that there were 3 categories of syndrome characteristics. Type 1 (134 cases): damp heat, blood stasis, deficiency of liver and spleen Qi; Type 2 (62 cases): deficiency of both Qi and Yin with severe deficiency of Qi, heat with severe dampness, blood stasis; Type 3 (27 cases): deficiency of both Qi and Yin with severe deficiency of Yin, stasis and heat or dampness. Analysis of the changes of the related laboratorial indexes among the three types of syndrome showed that Type 1 mainly manifested asthenia syndrome with sthenia syndrome, and its indexes of AST, ALT, GGT levels were markedly higher than those of Type 2 and Type 3, both of which mainly showed sthenia syndrome with asthenia syndrome, and that Type 3 was in active inflammation, deficiency of both Qi and Yin (deficiency of Yin > deficiency of Qi), and its FN, Alb, FV, FVII, PLT, PCT levels were obviously reduced. CONCLUSION: The multi-statistical methods can reveal the characteristics and regularity of TCM syndrome of hepatocirrhosis, and the 3 categories of syndrome characteristics basically conform to clinical manifestations. The result of TCM syndrome distribution and laboratorial indexes infer that damp heat is the pathological basis of hepatocirrhosis, and the degree of liver function disorder and liver damage may be the pathological basis of deficiency of Yin of both liver and kidney.
