RESUMEN
Objective To analyze the early risk factors of overweight and obesity in preschool children.Methods Using stratified cluster sampling,the data of 1 335 preschool children's physical examination in High-tech Zone,Urumqi,Xinjiang were collected,and the case group had 153 overweight and obese children,the control group had 1 182 non-overweight and obese children;a case-control study was conducted.The basic data of mothers and the basic data of neonatal birth were analyzed retrospectively.The univariate and unconditional multivariate logistic regression analysis was performed.Results The prevalence of overweight and obesity in preschool children in High-tech Zone in Urumqi was 11.5％.Non-conditional multivariate logistic regression analysis showed that children's age (OR=1.31,95％ CI:1.07-1.61),mother's pre-pregnancy BMI (OR=1.11 95 ％,CI:1.06-1.17) and whether mothers had gestational hypertension (OR=1.99 95％,CI:1.03-3.85) were the risk factors for overweight and obesity in preschool children (P＜0.05).Conclusion In Urumqi high school district preschool children's overweight and obesity rate was high;mothers with high BMI before pregnancy,and those with high blood pressure during pregnancy can increase the risk of overweight and obesity in children,preschool children's increased age may increase the risk of overweight and obesity in children.
RESUMEN
Objective: To examine the correlation between paliperidone plasma concentration and clinical efficacy in the patients with schizophrenia. Methods:Totally 50 schizophrenia patients were treated by paliperidone. The plasma concentration of paliperidone was monitored by RP-HPLC at the weekend of the 2 nd, 4 th and 6 th week, the clinical efficacy was evaluated using the positive and negative syndrome scale ( PANSS) , and the correlation between paliperidone plasma concentration and clinical efficacy was analyzed. Results:The mean plasma concentration of paliperidone was (31. 89 ± 17. 36) ng·ml-1 at the weekend of the 6th week, and no cor-relation was found between paliperidone plasma concentration and the clinical efficacy (r=0. 146,P=0. 074). Paliperidone plasma concentration in 12 patients with adverse drug reactions (ADR) was higher than that in the patients without ADR [(45. 87 ± 19. 21)ng ·ml-1 vs (27. 06 ± 11. 13) ng·ml-1, P <0. 01]. Conclusion: Paliperidone plasma concentration shows significant individual differences. With the increase of paliperidone plasma concentration, clinical efficacy isn't necessarily improved, while the incidence of ADR may be increased. Therefore, the monitoring of paliperidone plasma concentration is recommended to optimize the therapeutic reg-imen.
