Objective To evaluate the maternal age at delivery in Beijing and the effect of maternal age on pregnancy outcomes.Methods A retrospective analysis was conducted on 14 970 singleton pregnancies from 15 hospitals in Beijing from June 20th to November 30th in 2013.These hospitals were sorted by the numbers of delivery and chosen as clusters by systemic cluster sampling method.The data of age,diagnosis with gestational diabetes mellitus (GDM) and pre-eclampsia (PE),neonatal birth weight,gestational age at delivery,postpartum hemorrhage and infants admitted to the neonatal ICU (NICU) were collected.The 14 970 women were divided into 5 groups according to their ages at delivery:(1) less than 20 years (n=205),(2)20-＜30 years (n=9 228),(3)30-＜35 years (n=4 365),(4)35-＜40 years (n=1 017),and (5) 40 years and older (n=155).T-test and x2 test were used for between-group comparison,and logistic regression analysis was used to examine the association between age and the risk of adverse pregnancy outcomes.Results (1) The mean maternal age at delivery in 2013 in Beijing was (28±4) years old.Among them,205 (1.4％,205/14 970) delivered under 20 years of age;1 172 (7.8％,1 172/14 970) ≥35 years;and 155 (1.O％,155/14 970) at 40 years and older.(2) The prevalence of diabetes,hypertension,overweight and obesity increased with age,and the incidence of these conditions were 3.4％,4.3％ and 31.4％ in women with advanced age,respectively.(3) Compared with 20-＜30 years group,less than 20 years was associated with significantly lower incidence of GDM [adjust OR (aOR)=0.393,95％ CI:0.222-0.696] and cesarean section rate (aOR=0.549,95％CI:0.391-0.771),and higher incidence of preterm birth (aOR=2.144,95％CI:1.256-3.662).Moreover,30-＜35 years,35-＜40 years and 40 years and older groups all had significantly higher risk of GDM (30-34 years,aOR=1.513,95％CI:1.374-1.666;35-＜40 years,aOR=2.094,95％CI:1.786-2.455;≥40 years,aOR=2.174,95％CI:1.492-3.167),preterm birth (aOR=1.219,95％CI:1.021-1.455;aOR=1.644,95％CI:1.251-2.161;aOR=2.141,95％CI:1.209-3.792),cesarean section (aOR=1.373,95％ CI:1.268-1.486;aOR=2.960,95％ CI:2.550-3.435;aOR=4.332,95％CI:2.920-6.426) and NICU admission rate (aOR=1.236,95％CI:1.059-1.443;aOR=1.337,95％CI:1.018-1.756;aOR=2.389,95％CI:1.385-4.121),when compared to the 20-＜30 years of age group.Higher incidence of PE (aOR=1.292,95％CI:1.007-1.659) and postpartum hemorrhage (aOR=1.224,95％CI:1.048-1.429) were also noted in women of 30-＜35 years,compared to 20-＜30 years group respectively.Conclusion Both advanced maternal age and adolescent pregnancy are associated with increasing risk of adverse pregnancy outcomes.

Clear thermoplastic retainer is one of the most commonly used retention devices in orthodontics.However, studies about the electromyography (EMG) of temporalis muscle (TM) and masseter muscle (MM) in people with clear thermoplastic retainer are few. The purpose of this study was to observe the influence of clear thermoplastic retainer on the EMG of TM and MM in mandible posture position (MPP) , speaking [s] ,[z] and [a]. Choose people according to the standards, decide the situation by preliminary experiment. The EMG of TM, MM was studied before and after clear thermoplastic retainer was worn. Variance analysis was used to evaluate the differences. The results revealed that the EMG activity of TM?MM, viewed in MPP and when people said [s] ,[z] , was higher after clear thermoplastic retainer was worn. When people said [a], there was no significant difference.

Objective To discuss the diagnosis, treatment and following up of the cervical lesions(CIN～cervical carcinoma Ia 1) during pregnancy. Methods Fifteen pregnant women with cervical lesions were reviewed from Jan 1998～Oct 2003 in our hospital. Results Among the fifteen cases, 11 were diagnosed as CIN～ cervical carcinoma Ia 1 based on biopsy results under copolscopy. Ten of the 11 cases had copolscopy repeated every 8 weeks and delivered at term. The left one woman terminated the pregnancy in the first trimester due to carcinoma in situ (CIS) invasion to glands. Among those 10 cases who progressed to term, four were stable during pregnancy (CINⅡ,CINⅢ,CIS and cervical carcinoma Ia1, one for each) and had the same pathology postpartum as antepartum; three had CIN I during pregnancy but changed to inflammation postpartum;one had CIS involved in glands prepartumly while CINⅡ～Ⅲ postpartumly; one had CINⅢ prepartumly and progressed to CIS involved in glands confirmed after conization postpartumly. One woman was missing after delivery. Conclusions Cervical lesions (CIN～Ia 1) less likely get worse during pregnancy. Conservative management is possible if regular cytology, copolscopy and bioposy when necessary are available. Re examination is necessary within two months after birth. Routine examination for women who have no pap smear within the last one year period would be helpful in detecting cervical lesions during pregnancy.
