Objective:To evaluate the relationship between the phthalate ester exposure and the population obesity with Meta-analysis, and to provide a new idea for prevention and control of obesity. Methods:A comprehensive search was performed in English databases (Pubmed, Web of Science, The Cochrane Library, Elsevier Science Direct and OVID) and Chinese databases (Sinomed database, CNKI database, VIP database, Wanfang database).The studies about the relationship between phthalate ester exposure and the population obesity were retriveded.The Chinese and English studies were selected according to the inclusion criteria and exclusion criteria.Meta-analysis was performed using RevMan 5.3 software.Results:Six studies were finally obtained, involving 1259 samples.The Meta-analysis results showed that the monobutyl phthalate (MBP) level in urine of the obesity population was increased 4.1 times compared with the normal population (95%CI:1.43-6.76);while the combined effect values of dibutyl phthalate (DBP), di-2-ethylhexyl phthalate (DEHP) and diethyl phthalate (DEP) level in serum of the population in two groups were 1.17 (95%CI:0.64-1.69), 0.80 (95%CI:0.13-1.48), and 0.72 (95%CI:-0.19-1.63);the combined effect values of monoethylhexyl phthalate (MEHP) and monoethyl phthalate (MEP) levels in urine were 1.75 (95%CI:-0.45-3.96) and 2.75 (95%CI: 0.36-5.15);there were no significant differences (P>0.05).Conclusion:The elevated MBP levels in the urine may be a risk factor for obesity in the population, suggesting that MBP may contribute to obesity.

Objective:To explore the category,prevalence and related factors of comorbidities associated with Tourette syndrome.Methods:125 patients with TS according to CCMD-3(Chinese Classification of Mental Disorders,3rd edition)were assessed with a self-designed family circumstance questionnaire,YGTSS,CBCL,Leyton obsessive-compulsive scale,and Conner's Child Behavior Checklist.Results:Of 125 TS patients,the comorbidities included attention deficit and hyperactivity disorder(ADHD,41.6%),obsessive-compulsive disorder(OCD,25.6%), anxiety disorders(8.0%),depressive disorders(4.8%),conduct disorders(8.0%),self-injurious behavior(3.2%),and sleep disorder(2.4%).Conclusion:There are many kinds of comorbid disorders at high prevalence in TS patients. These comorbidities adversely influence the therapy and prognosis of TS and are taken as the possible reasons for social function deficit.

Standardized specialist training is key to postgraduate medical education. China is introducing the specialist training programs, yet without covering specialist training in obstetrics and gynecology(O&G). Shanghai took the lead in 2003 to pilot O&G specialists training programs within the region. This study introduced the specialist training programs in O&G in the US, and compared them with those in Shanghai, and recommending on launching O&G specialist training nationwide based on China′s specifics.
