ABSTRACT
Objective To investigate the prevalence of dyspepsia and the relationship between dyspepsia,psychological and social factors among the college students in Naning city,and to improve the prevention and treatment of dyspepsia in this region.Methods Rome Ⅲ diagnostic questionnaire for adult dyspepsia,Chinese college student mental health scale (CCSMHS),Chinese college student psychological stress scale (CCSPSS),Chinese college student adaptation scale (CCSAS) and Chinese college student personality scale (CCSPS) were performed through interview survey in 2 580 Nanning college students.Chi square test and rank sum test were used to compared differences between groups.Correlation analysis was performed by Pearson correlation and Logisitic regression analysis.Results A total of 2 520 qualified Rome m questionnaires were recovered.The prevalence of dyspepsia in Nanning college students was 5.36％(135/2 520).The most common appearance of dyspepsia in college students were dislike of drinking tea (86.96％(100/115) vs 79.10％(1 605/2 029)),dislike of pickled food (85.22％(98/115) vs 76.29％(1 548/2 029)) and missing meals (40.87％(47/115) vs 30.31％(615/2 029)),the differences were statistically significant (x2 =4.122,4.860,5.685;all P＜0.05),while the dyspepsia was not related with drinking,smoking and taking raw,cold or spicy food (all P＞0.05).The results of multifactor regression analysis showed that the prevalence of dyspepsia was not correlated with diet.Among the twelve dimensions of psychological health,the somatization,anxiety,depression,low self-esteem,social withdrawal,sexual psychology,paranoia,force,dependency,psychotic tendencies of dyspepsia group were significantly higher than those with non-dyspepsia group (x2 =16.981,21.805,12.520,13.539,6.998,6.154,15.013,9.457,10.715,4.260,all P＜0.05).Among the seven dimensions of psychological stress,study pressure and development pressure were negative life events,and their of dyspepsia group were significantly higher than those with non-dyspepsia group (x2 =6.216,Fisher exact probability test,both P＜0.05).There was no statistically significant difference between two groups in the seven personality,such as active,outgoing,tenacity,rigorous,altruism,affectionate and easy-going (all P＞0.05).Among the seven dimensions of adaptation,the adaptation to campus life,emotion and career choice of dyspepsia group were significantly lower than those with non-dyspepsia group (x2 =8.223,8.148,5.713,all P＜0.05).While there was no statistically significant difference between two groups in the other four dimensions of adaption,such as relationships,learning,ego and satisfaction (all P＞0.05).The results of Logistic regression analysis in psychological health,stress and adaption of dyspepsia group and non-dyspepsia group indicated that dyspepsia was associated with somatization (odds ration (OR) =1.610,95％ confidence interval (CI) 1.012-2.559),anxiety (OR=1.955,95％CI 1.216-3.142) and the study pressure (OR=2.159,95％CI 1.106-4.213).The results of Pearson correlation analysis in study pressure,somatization and anxiety of dyspepsia group showed that both somatization and anxiety were correlated with study stress in dyspepsia group (r=0.314,0.323;both P＜0.05).Conclusions Dyspepsia is a common symptom in Nanning college students.Students with dyspepsia have different degrees of psychological problems which are mostly anxiety and somatization.And study stress as a negative event is the major stress factor.
ABSTRACT
Objective To analyze the living polymerization porcelain inlay restoration dental pulp large clinical efficacy of dental defects and infection prevention. Methods Forty-two cases patients with dental defects after the live pulp tooth of large teeth 48, were randomly divided into experimental group (24 teeth) and the control group (24 teeth). The experimental group tooth preparation, polymerization porcelain inlay restoration; Control group metal ceramic crowns, resin adhesive application RelyX Unicem 2-year follow-up and evaluated of the efficacy analysis infection prevention methods. Results The color matching, shape matching, secondary caries, marginal fit, wear and fracture strengths in the experimental group were better than the control group, the difference was statistically significant (P<0.05). Conclusion Living polymerization porcelain inlay restoration dental pulp excellent clinical efficacy large area of dental defects, pa-tients followed up show functions fine roles in shape, color matching after 2 years.
