Abstract:
Objective To explore the relationship between carotid intima-media thickness (CIMT) and glycemic control in community type 2 diabetes mellitus (T2DM) patients. Methods A community-based study for T2DM patients aged over 40 years was conducted in three rural communities in Beijing. Every participant underwent hemoglobin A1c (HbA1c) assessment, CIMT measurement, physical examination, biochemical test and a questionnaire investigation. According to the level of HbA1c, T2DM patients were divided into well-controlled group, moderately controlled group and poorly controlled group and then the association between CIMT and glycemic control among T2DM patient was analyzed. Results A total of 720 T2DM patients were recruited. The average age was 59.06±7.50 years old and the mean T2DM duration was 6.3 years. Correlation analysis showed CIMT was positively associated with HbA1c (rs=0.182, P<0.001). The thickness increase rate of CIMT for well-controlled (HbA1c<6.5%), moderately controlled (6.5%≤HbA1c<8.0%), and poorly controlled (HbA1c≥8.0%) groups were 21.98%, 28.94% and 38.11% respectively (χ2=13.78, P=0.001). Logistic regression analysis showed that after adjusting for age, sex, cardio-cerebral vascular disease history, anti-diabetic drug use, T2DM duration, indexes of blood pressure and lipids, the thickness increase rate of CIMT was associated with HbA1c (OR=1.18,95% CI:1.07-1.31). Compared with the well-controlled group, poor glycemic control remained a risk factor for the elevation of CIMT (OR=2.17, 95% CI:1.34-3.51). Conclusions The level of glycemic control among T2DM patients was associated with CIMT. Poor glycemic control (HbA1c≥8.0%) might be a risk factor for the development of atherosclerosis among T2DM patients and its function is independent of blood pressure and lipid level.

Abstract:
Objective To investigate the prevalence and influencing factors of dyslipidemia in the elderly with prediabetes in rural areas in Yiyang. Methods The background characteritics and laboratory results of the elderly with prediabetes were collected by questionnaire and laboratory testing after screening prediabetes in rural areas during April to July 2015. Binary unconditional logistic regression was used to analyse the influencing factors of dyslipidemia among the elderly with prediabetes. Results The prevalence of dyslipidemia in the elderly with prediabetes in rural areas was 28.3% (95% CI: 24.2%-32.5%). The prevalence of males was 25.6% (95% CI: 19.1%-32.0%), and the prevalence of females was 30.3% (95% CI: 24.6%-36.0%). Results from the binary unconditional logistic regression indicated that increasing age, high body mass index, high waist to hip ratio, hypertension, smoking, lack of exercise, poor diet were risk factors of dyslipidemia in the elderly with prediabetes. Conclusions The prevalence of dyslipidemia in the elderly with prediabetes in rural areas in Yiyang is higher than that in general population. In order to control risk factors of dyslipidemia, and to reduce the incidence of dyslipidemia among this population, health monitoring and health education should be improved in future.

Abstract:
Objective To understand the awareness of risk factors for hypertension and diabetes among urban community residents and it's influencing factors, in order to further provide basis and references for health education and health promotion based on community centers. Methods Fourteen community health service centers were selected from twelve provinces in China using convenience sampling method. Informed written consent was also obtained from all participants involved in this study. Results Of 6 620 residents, the higher age of community residents had the lower awareness rate of risk factors for hypertension and diabetes(χ2=131.382,P<0.001). The awareness rate was much higher among residents with hypertension or diabetes than those without disease (χ2=8.962, P=0.003). Moreover, multivariate Logistic analysis indicated that monthly family income, work status and suffering hypertension or diabetes were important determinants of the awareness. Conclusions The awareness rate of risk factors for hypertension and diabetes among community residents was low, and it's very crucial to strengthen the health education to elderly in community.

Abstract:
Objective To describe the mental health status of elderly patients with chronic diseases and identify associated influencing factors, also to evaluate the association between mental health status and coping modes and propose some suggestions to improve their mental health. Methods Self-designed questionnaire, self-reporting inventory (SCL-90) and simplified coping style questionnaire (SCSQ) were used to investigate the elderly patients with chronic diseases. Results 513 cases (40.6%) were screened as positive. Except interpersonal relationship sensitiveness, the scores of other factors were higher than the average score of normal Chinese people. Apart from marital status and residence areas, the other demographic characteristics, physical health indicators and economic variables were all influencing factors for SCL-90 scores. The correlation coefficient between positive coping mode and SCL-90 score was -0.120 (P<0.001), the correlation coefficient between negative coping mode and SCL-90 score was 0.131 (P<0.001). Conclusions The elderly patients with chronic diseases have serious psychological problems, its influencing factors are complex and their coping modes tend to be negative. Reasonable guidance is also needed to improve their mental health status.

Abstract:
Objective To analyze the relationship between co-expression of MYC/Bcl-2 proteins and clinical features and prognosis of diffuse large B-cell lymphoma(DLBCL), so as to explore the significance of MYC/Bcl-2 protein co-expression in DLBCL. Methods The immunohistochemical examination of MYC/Bcl-2 protein expression was conducted for lymphoma tissue samples of 89 cases of DLBCL patients who were pathologically confirmed. Next, a single factor comparison with progression free survival was made to such factors as whether to apply rituximab, primary sites,ages,genders,Ann Arbor stage,international prognostic index,immunohistochemistry Hans typing, Ki-67 expression and MYC/Bcl-2 protein co-expression. Then the factors having a statistically significant difference were included for multi-factor regression analysis. Results There were 29 cases of MYC/Bcl-2 co-expression patients, accounting for 32.6%. Through single factor comparison, the factors of whether to apply rituximab, age> 60 years, stages Ⅲ-Ⅳ, international prognostic index =3-5 scores, and MYC/Bcl -2 coexpression were adverse prognostic factors (all P<0.05); and the factors of whether to apply rituximab, age>60 years, stages Ⅲ-Ⅳ, international prognostic index=3-5 scores, and MYC/Bcl-2 co-expression had statistical significance (all P<0.05) through multi-factor regression analysis. Conclusions MYC/Bcl-2 co-expression is an independent prognostic risk factor for DLBCL.

Abstract:
Objective To explore factors influencing the discrepancy between clinical and pathological lymphoma diagnosis and their effects on the lymphoma treatment. Methods 232 hospitalized patients clinically or pathologically diagnosed with lymphoma between January 1st, 2012 and December 31st, 2014 were included in this study. The discrepancy between clinical and pathological diagnosis was assessed and the effects on the lymphoma treatment was evaluted. Results The diagnostic reliabilities of nodal lymphoma and diffuse large B-cell lymphoma were higher than those in extra-nodal lymphoma and non-diffuse large B cell lymphoma respectively. Reliability of pathological diagnosis was affected by diagnostic methods whereby the highest reliability incision biopsy could be 73.7%. There were 14(6.0%) inconsistent cases between clinical and pathological diagnosis, three cases resulted in moderate effects and 11 cases lead to mild effects on treatment. Inconsistencies were mainly due to lesion locations, different pathological diagnostic methods and pathological types of lymphoma. Conclusions The difficulty of lymphoma diagnosis, the locations and pathological diagnostic methods of lymphoma may contribute to the discrepancy between clinical and pathological diagnosis of lymphoma. Effective communication between clinicians and pathologist is required to get a more accurate diagnosis of lymphoma.

Abstract:
Objective To establish a relative predictive model of pathology of lupus nephritis based on clinical and laboratory results. Methods Lupus nephritis patients who had renal biopsies were consecutⅣely recruited in our hospital from 2011 to 2015. 201 patients had already received an over two months treatment with glucocorticoid, but they still had positive proteinuria. The clinical manifestations and laboratory indexes of these patients were analyzed. Epi Data 3.1 and SPSS 21.0 were used for statistical analysis. Results Seventeen cases with class Ⅱ lupus nephritis, 26 cases with class Ⅲ lupus nephritis, 135 cases with class iv lupus nephritis and 23 cases with classⅤ lupus nephritis. In single analysis, patients with proliferative lupus nephritis were younger and had earlier first-onset age, higher SLEDAI, more anemia, lower serum levels of C3 complement components, higher positive rate of anti-C1q antibody (64.0%) and anti-dsDNA antibody (53.4%). Patients with membranous lupus nephritis had older first onset age and lower positive rate of anti-dsDNA antibody (13.0%). Proteinuria turned negative rate was 67.4% in the supine position in patients with mesangioproliferative lupus nephritis. In logistic regression anlysis, patients with mesangioproliferative lupus nephritis had lower SLEDAI and higher incidence of disappearance of the protein loss in the supine position. Patients with proliferative lupus nephritis had higher SLEDAI, positive rate of proteinuria and anti-dsDNA antibody. Patients with membranous lupus nephritis had later first-onset age and lower positive rate of anti-dsDNA antibody. Conclusions The predictive model of pathological classifications of lupus nephritis has been established. Lower SLEDAI and higher incidence of negative proteinuria test in the supine position could be the strong predictors for class Ⅱ lupus nephritis. Higher SLEDAI, positive rate of proteinuria and anti-dsDNA antibody may predict class Ⅲ or iv lupus nephritis. Later first-onset age and lower positive rate of anti-dsDNA antibody may predict class Ⅴ lupus nephritis.

Abstract:
Objective To discuss how to deal with missing data and intra-class correlation in longitudinal follow-up data, and fully use the collected data to reflect the overall information.Methods Firstly, longitudinal complete data and missing data were simulated; Secondly, apply multiple imputation methods(MI) and multilevel model(MLM) were applied to deal with these data sets; Moreover, randomized block analyze of variance was used to analysis each data sets; Finally, an example was used to validate the simulation results.Results The results of different missing type coincided with those of different missing proportion: the deviation of MI with MLM was less than simple MLM. The more filling times, the smaller the deviation. As the missing rate increased, deviation of all methods became larger. The results got more stable in the present of large sample size. The simulation results were also verified by example analysis.Conclusions MI with MLM can provide effective and reasonable results in the longitudinal follow-up data.

Abstract:
Objective To explore the application of ARIMA-GRNN hybrid model, ARIMA model and BPNN model in the prediction on incidence of hepatitis A in China and compare the predicative effect among them. Methods The data of incidence of hepatitis A from January 2004 to December 2014 in China was collected and SPSS 13.0 was used to construct ARIMA model, Matlab 8.0 was used to establish BPNN model and ARIMA-GRNN hybrid model, afterwards the data in 2014 was used to evaluate the effect of prediction. Results The average relative error of the three models, which was established to predict the incidence of hepatitis A sequence in China, fitness was 7.29785, 5.86174 and 4.91063 for ARIMA model, BP network model and ARIMA-GRNN hybrid model, respectively. The average relative error of accuracy predicted by ARIMA model, BP network model and ARIMA-GRNN hybrid model in 2014 was 6.44 067, 5.74 400 and 4.86 292, respectively. The results of other model evaluation indices, such as average error rate, mean square predict error and mean absolute error, also showed that ARIMA-GRNN hybrid model had the minimum error. Conclusions ARIMA-GRNN combination model is superior to the ARIMA model and BPNN model.
