Objective To study the relationship of three-dimensional power Doppler ultrasonographic parameters and endocrine profile in different symptoms of patients with polycystic ovary syndrome(PCOS).Methods One hundred and forty nine women with PCOS were divided into two groups,which included obese PCOS(OB-PCOS) group and non-obese PCOS (NOB-PCOS) group.The ultrasonic parameters such as follicle number,ovarian average diameter,ovarian volume,stromal volume,follicle volume,vascularization index(Ⅵ),flow index(FI),vascularization flow index(VFI) were measured and compared.Serum levels of luteinizing hormone (LH),follicle stimulating hormone (FSH),progesterone (P),estradiol (E2),testosterone(T),prolactin (PRL),sex hormone binding globulin (SHBG),free androgen index (FAI),fasting plasma glucose (FPG),fasting insulin (FINS),homeostasis model assessment-IR(HOMA-IR) were also measured and compared.The correlation of the ultrasonic parameters and hormonal factors were analyzed.Results The follicle number,ovarian average diameter,ovarian volume,stromal volume,follicle volume,FI and VFI,FINS,HOMA-IR,FAI of OB-PCOS were significantly higher than those of NOB-PCOS (P ＜0.01 or 0.05),the FSH,SHBG were significantly lower than those of NOB-PCOS (P ＜0.05 or 0.01).In OB-PCOS group,the follicle number was significantly associated with FSH(r =0.771,P ＜0.01).The ovarian volume,stromal volume,FI and VFI were significantly associated with HOMA-IR(r =0.412,0.842,0.389,0.415,P ＜0.05 or 0.01),FI was significantly associated with FAI (r =0.812,P ＜0.01).In NOB-PCOS group,the follicle number,ovarian volume were significantly associated with FAI(r =0.472,0.552,P ＜0.05)..Conclusions There are some different characters in ultrasonography and endocrine parameters between obese and non-obese PCOS patients.

Objective To assess prenatal heart disease screening program by ultrasound. Methods A total of 11 544 second-trimester screening scans were performed before 24 weeks′ gestation on 11 410 women between February 2004 and May 2007 in Obstetrics and Gynecology Hospital of Fudan University. Fetal heart screening was based on four-chamber and outflow tract views( left ventricular outflow + three vessel view). The sensitivity and specificity of different views were evaluated. Follow-up data of newborns was obstained. Results (1) Among 11 544 cases, 48 cases of congenital heart disease (CHD) were diagnosed in utero. Six cases were false negative, and 2 cases were false positive. The incidence of CHD was 0.47% (54/11 544). (2) Thirty-three CHDs were detected based on the four-chamber view, including 18 ventricular septal defect (9 with conotroncal anomalies),6 anomalous atrioventricle valve, 9 disproportion of left/right ventricle. The sensitivity of the four-chamber view alone was 61.11% (33/54), and the specificity was 99. 98% ( 11 488/11 490). Fifteen CHDs were detected based on the left ventricular outflow and three vessel views, including 1 pulmonary atresia, 3 pulmonary valve stenosis, 2 transposition of the great arteries ( TGA ), 1 pulmonary stanosis with TGA, 6 tetralogy of Fallot, and 2 pulmonary stenosis. The sensitivity of the combination of the four-chamber and outflow tract views was 88. 89% (48/54), and the specificity was 99. 98% (11 488/11 490). (3)Of 48 CHDs,11 cases were eceompanied by other malformations. Eleven cases were performed amniocentesis, amony whom 5 cases were trisemy 21. Conclusion The screening program based on four-chamber and outflow tract views shows good sensitivity and excellent specificity. Our prenatal heart screening program is clinically feasible.

Objective To establish the reference ranges for fetal cardiac axis in the mid-second trimester and to evaluate the use of fetal cardiac axis in prenatal diagnosis.Methods 6744 unselected singleton pregnancies were enrolled from September 2008 to October 2010.Routine screening scan of second trimester and fetal echocardiography were performed at 18- 23+6 weeks gestation.Fetal cardiac axis was measured on the four-chamber view of the heart.Results The 6744 fetuses had a mean cardiac axis of (37.03 ± 6.10)°,ranging from 9.80° to 102.41°. Using above or below 95％ range of population (26.63° -49.40°) as a cut-off,there were significant difference of cardiac axis between normal group [(36.96 ± 5.91)°,P ＜0.01] and the group with heart defects [(43.12 ± 15.67)°,P ＜0.01],the group with intrathoricic anomalies or abdominal wall defect [(51.74 ± 15.97)°].ConclusionsThe reference ranges of fetal cardiac axis for local population in mid-second trimester may helpful for detecting congenital defects.Presence of an abnormal cardiac axis in the fetuses is associated with a substantial risk of congenital heart disease and/or other extra cardiac defects.

Objective : To study the effect of crisaborole on imiquimod (IMQ) Ⅳinduced psoriasis in mice. Methods: Forty eight Balb/c mice were randomly divided into crisaborole group (7. 5 , 15 , 30 mg/cm2），halometasone group ( 15 mg/cm2 ) , model group and normal group. IMQ was applied to the back of mice to establish the psoriasis model. Psoriasis area and severity index ( PASI) score was calculated , pathological changes , skin epidermal thickness and inflammatory cell infiltration in the dermis were observed by HE staining. The expressions of keratin (K) 1 , K10 , K6 , K16 and K17 in skin lesions were detected by Western blot and immunohistochemistry. The levels of cyclic adenosine monophosphate ( cAMP) , protein kinase A ( PKA) and phospho⁃cAMP response element binding protein (p⁃CREB) were detected. Results : Compared with the model group , the PASI score of the crisaborole group decreased , the expression levels of proliferative keratin ( K6 , K16 and K17 ) decreased( F = 12. 62、19. 41、28. 39 ,P < 0. 01) , and the expression levels of differentiation keratin (K1 and K10) increased(F = 27. 95、9. 64 , P < 0. 01) . Conclusion Crisaborole plays a therapeutic role in IMQ⁃induced psoriasis in mice by regulating the abnormal proliferation and differentiation of keratinocytes.
