Objective To study the relationship between the level of serum epithelial fatty acid binding protein (E-FABP) and cardiovascular disease in obese children. Methods Thirty children with metabolic syndrome (MS), 32 obesity children with no MS and 50 healthy children were recruited. Serum E-FABP and glucose/lipid metabolic indices were measured. Results Com-pared with the healthy children, levels of serum E-FABP in MS children were signiifcantly elevated (P=0.001). Compared with obesity children, levels of serum E-FABP of MS children were elevated, but the difference was not signiifcant (P>0.05). The cor-relations of E-FABP with waist to hip ratio, waist-to-height ratio, atherogenic index, fasting insulin, insulin resistance index were positive (P<0.05). According to the multivariate stepwise regression analysis, E-FABP was the independent risk of atherogenic index (P=0.018). Conclusions E-FABP plays a role in the development of atherosclerosis in obesity and MS.

Objective:To assess the prognostic value of modified Charlson comorbidity index (mCCI) combined with serum albumin for long-term prognosis in peritoneal dialysis (PD) patients.Methods:From January 1, 2007 to June 30, 2015, patients who started PD in Nanjing Drum Tower Hospital were enrolled in this retrospective cohort study. Clinical data including gender, age, underlying diseases, laboratory examination and prognosis were collected. The mCCI at the beginning of PD was calculated. Whether the duration of PD exceeded 5 years was used as an indicator to evaluate the prognosis. The patients were divided into≥5 years group and<5 years group according to the duration of PD, and the data were compared between the two groups. Cox regression model was constructed to analyze the influencing factors of all-cause death in PD patients. Multivariate logistic regression model and receiver operating characteristic (ROC) curve were used to analyze the predictive value of mCCI and serum albumin levels on whether patients could maintain long-term PD.Results:Of the 183 patients included [males 106(57.9%), females 77(42.1%); (53.35±16.50) years old; 162 cases (88.5%) with hypertension, 55 cases (30.1%) with diabetes], 97 cases had PD duration for ≥5 years and 86 cases less than 5 years. The overall 5-year technical survival rate was 65.1%. At the beginning of PD, compared with the dialysis age≥5 years group, the patients in the dialysis age less than 5 years group had older age, higher mCCI, lower serum albumin level, and higher C-reactive protein (CRP) level (all P<0.05), but there were no significant differences in gender, education level, electrolyte, mean arterial pressure, high densitv lipoprotein (HDL), low-density lipoprotein (LDL) and PD adequacy index between the two groups (all P>0.05). Multivariate logistic regression analysis showed that increased age ( OR=1.022, 95% CI 1.000-1.043, P=0.046), increased mCCI ( OR=1.620, 95% CI 1.300-2.018, P<0.001) and decreased serum albumin ( OR=0.807, 95% CI 0.730-0.893, P<0.001) were independent predictors for the duration of PD<5 years. ROC curve analysis showed that the area under ROC curves ( AUC) of mCCI, serum albumin level and combined prediction probability of the two for the duration of PD<5 years were 0.647(95% CI 0.568-0.727), 0.655(95% CI 0.577-0.734), and 0.767(95% CI 0.700-0.835), respectively, indicating that the accuracy of combined parameters to predict survival outcome was higher than that of any single parameter. Multivariate Cox analysis showed that increased age ( HR=1.073, 95% CI 1.046-1.100, P<0.001), increased mCCI ( HR=1.198, 95% CI 1.044-1.375, P=0.010) and decreased serum albumin ( HR=0.904, 95% CI 0.843-0.969, P=0.004) were independent influencing factors for all-cause death in PD patients. Conclusions:Old age, high mCCI and low serum albumin level are influencing factors for dialysis age<5 years and all-cause death in PD patients. mCCI combined with serum albumin level can improve the accuracy of predicting the long-term dialysis in PD patients.

The validity of the recently recommended HbA1C criterion by the American Diabetes Association (ADA) in identification of dysglycemia in children with obesity was evaluated. 293 obese children underwent oral glucose tolerance test. Receiver operating characteristic ( ROC ) curve analysis was used to examine the sensitivity and specificity of fasting plasma glucose (FPG) and HbA1C in identifying dysglycemia. The results showed that the prevalence of type 2 diabetes mellitus (T2DM) was 3.8％ and prediabetes 16. 0％ based on plasma glucose standard. 4. 1％ and 25.6％ were categorized as T2DM and “at high risk of diabetes mellitus” based on both HbA1C and plasma glucose criteria. HbA1C was more efficacious than FPG in detecting abnormal glucose tolerance as shown by the areas under the curve in ROC of 0. 875 and 0. 713 respectively (P＜0. 01 ). The sensitivity and specificity were 60. 5％ and 86. 8％ at HbA1C ≥5.7％, and 30. 5％ and 94.0％ at FPG ≥ 5.6 mmol/L.

Objective To study the diagnostic value of glycosylated hemoglobin(HbA1c)combined with ho-meostasis model assessment of insulin resistance( HOMA-IR)in obese children with prediabetes. Methods Five hundred and ninety-five obese children diagnosed at Outpatient Department of Pediatrics,Tianjin Medical University General Hospital were enrolled in the study from October 2012 to March 2016. Oral glucose tolerance test(OGTT)and HbA1c test were performed after fasting 8 to 10 hours for all the subjects. According to the World Health Organization (WHO)criteria,the obese children were divided into non-prediabetes group(483 cases)and prediabetes group(112 cases). The levels of HOMA-IR and HbA1c were compared between 2 groups. The receiver operating characteristic (ROC)curve was drawn for screening prediabetes,and the diagnosis value of area under curve( AUC)and different cutoff value were calculated. Logistic regression model was used to analyze the combined diagnosis of prediabetic AUC with preserved probability as a single variable and ROC curve. Z test was used to compare the statistical differences of each AUC. Results The levels of HbA1c and HOMA-IR of the prediabetes obese children group[(5. 65 ± 0. 36)%and 11. 60 ± 8. 86]were all higher than those of the non-prediabetes obese children group[(5. 47 ± 0. 32)% and 6. 49 ± 4. 61],and there were significant differences between 2 groups(all P<0. 01). The AUC of HbA1c ROC for prediabetes was 0. 633. When the cutoff was 5. 585%,the sensitivity and specificity were 0. 584 and 0. 601,respective-ly. The AUC of HOMA-IR ROC for prediabetes was 0. 758. When the cutoff was 7. 244,the sensitivity and specificity were 0. 779 and 0. 669,respectively. When combined with HOMA-IR and HbA1c,the AUC was 0. 764. Compared with HbA1c,there were significant differences in AUC of ROC curve between HOMA-IR alone or HOMA-IR com-bined with HbA1c in the diagnosis of prediabetes mellitus(all P<0. 01). There was no significant difference in AUC of ROC curve between HOMA-IR alone and HOMA-IR combined with HbA1c in the diagnosis of prediabetes melli-tus(P>0. 05). Conclusions Only HOMA-IR or HOMA-IR combined with HbA1c may be the optimal indexes for diagnosing obese children with prediabetes.

We studied the effects of simulated microgravity on mouse oocytes maturation, and analyzed whether the tail-suspended model can be applied to investigate simulated microgravity effects on reproductive processes in female mice. Mouse oocytes were cultured in vitro with microgravity simulated by a rotating wall vessel bioreactor and by tail-suspended model, and the maturation rate of the mouse oocytes in the two models were examined in vivo. The maturation rate of mouse oocytes cultured in simulated microgravity was 8.93%, and that was 72.33% in 1g gravity. In ratio, oocyte maturation rate had no significant difference between the rotational group and control group. Microgravity simulated by the tail-suspended model inhibited mouse oocytes maturation and increased the rate of oocytes abnormity. The maturation rate of tail-suspended mouse oocytes was 14.54%, which was significantly lower than that of control group. Tail-suspended model should be an ideal model to investigate simulated microgravity effects on reproductive processes of female mice.
