Objective To investigate the status of deciduous caries and early childhood caries among 3-5 year-old children of Uyghur and Chinese in Urumqi, and to explore the correlative factors of early childhood caries. Methods According to the criteria recommended by the Third National Oral Health Investigation, and Oral Health Surveys: Basic Methods of World Health Organization, the deciduous caries of 474 Urghur and Chinese children aged from three to five in nine kindergartens were clinically examined. Data were collected by questionnaire from their parents, and the result waw analyzed using Logistic regression analysis. Results The result of logistic regression analysis showed that the variables including nationality, frequency of drinking milk, eating cookie or drinking sweet beverage before sleep, brushing teeth with help, and educational background of the mother were closely related to the incidence of infantile caries. Conclusion The nationality, frequency of drinking milk, eating cookie or drinking sweet beverage before sleep, brushing teeth with help, and educational background of the mother are correlative factors of early childhood caries. Necessary methods for prevention of deciduous caries must be taken into consideration as early as possible, and the bilingual propaganda for preventing and treating caries should be also highly emphasized.

Methods Self-made questionnaire was applied in the investigation on 336 students who attended the MBA program of Sichuan University from 2006 to 2010. The investigation results were collected and analyzed by using logistic regression analysis. Results A total of 320 (89.65%) valid questionnaires were retrieved among all the 336 questionnaires assigned. In all the students, 86.2% were contented with the current situation of scientific training program. The content of the course practice, management of training mode and whether there was a rich case analysis were influential factors for students′ satisfaction degree (Plt;0.05). Conclusions The influential factors for students’ satisfaction degree should be taken into consideration in order to better carry out the MBA hospital management training program. More emphasis should be paid on the course design, training mode adjustment and selection of cases, in order to cater for modern hospital managers.
ObjectiveTo investigate the correlative factors for the efficacy of surgical treatment for single segment degenerative lumbar spinal disorders. MethodsFrom October 2008 to November 2010, a prospective non-randomized controlled study was carried out on 179 patients who were diagnosed to have L4-5 degenerative lumbar spinal disorders and underwent surgical treatment. Ninety-seven patients were included in our study, including 64 males and 33 females, aged between 21 and 86 years old, averaging 49.0. The follow up lasted for an average of 18.9 (12-27) months. The correlative factors including age, sex, body mass index, preoperative psychological state and degree of low back pain, surgical methods, combination with adjacent segment degeneration and recurrence state were analyzed. Single and multiple-factor Logistic regression analysis was used to determine the relationship between independent factors and surgical results of lumbar degenerative disease. ResultsAt the last follow-up, Japanese Orthopaedic Association scores were improved to 22.40±3.18 with an improving rate of (68.5±15.7)% compared with the preoperative condition (7.61±3.09), and the difference was significant (t=-33.031, P<0.001). Univariate analysis showed that all factors were variables associated with the surgical results excluding sex and age (P<0.05). Multiple-factor logistic regression analysis showed that the preoperative psychological state, combination with adjacent segment degeneration and surgical methods had important impact on the surgical results (P<0.05). ConclusionSurgical treatment of lumbar degenerative disease is effective. The preoperative psychological state, combination with adjacent segment degeneration and surgical methods are important factors associated with the surgical results.
ObjectiveTo learn the outcomes of hepatitis B virus (HBV)-related acute-on-chronic liver failure (ACLF) cases after artificial liver support system (ALSS) treatment and the relevant factors correlated with the clinical outcomes. MethodsIn the period from January 2011 to June 2014, 321 patients with HBV-ACLF were admitted to West China Hospital. The clinical data at baseline, before and after treatment were analyzed by univariate and multivariate logistic regressions to identify the independent risk factors correlated with 30-day outcomes. ResultsOf all the 321 patients, 233 survived and 88 died by the end of a 30-day observation. The univariate analysis identified that the incidences of cirrhosis, hepatorenal syndrome and peritonitis in the death group were significantly higher (P<0.05). The model for end-stage liver disease values, white blood cells (WBC), blood ammonia, creatinine and total bilirubin (TBIL) at different stages in the death group were significantly higher than those in the survival group (P<0.05). In the death group, the HBV-DNA, TBIL decrease after triple ALSS treatments, baseline prothrombin time activity (PTA) and PTA level after triple ALSS treatments were significantly lower (P<0.05). The multivariate logistic regression indicated that WBC (OR=2.337, P<0.001) and TBIL level after triple ALSS treatments (OR=4.935, P<0.001) were independent predicting factors for death within 30 days after ALSS treatment; HBV-DNA (OR=0.403, P<0.001), the decrease of TBIL after triple ALSS treatments (OR=0.447, P<0.001) and PTA level after triple ALSS treatments (OR=0.332, P<0.001) were protecting factors for the 30-day prognosis. ConclusionThese five factors including WBC, HBV-DNA, PTA, TBIL and TBIL decrease after triple ALSS treatments influence the short-term prognosis for HBV-ACLF patients, which are valuable for decision making in clinical practices.
