[Summary] A 32 year-old woman in the third trimester of pregnancy was admitted for severe acute pancreatitis due to hypertriglyceridemia . During hospitalization she developed multiorgan dysfunction , infected pancreatic necrosis , abdominal compartment syndrome and intrauterine fetal death . She was successfully treated by multidisciplinary team including department of emergency medicine , ICU, gastroenterology, obstetrics, endocrinology, ultrasonography, radiology, infectious disease, nutrition and surgery.

Immune cells interact with their secreted cytokines forming immune microenvironment that plays an important role in the treatment resistance.Immune microenvironment induces tumor tolerance by reducing the anti-apoptotic pathway,mediating immune tolerance,inducing epithelial mesenchymal transformation and the formation of tumor stem cells,reducing the curative effect.Tumor immunotherapy has become a hot topic in the field of tumor therapy research.

Objective To evaluate changes in morphology of the cesarean scar and uterus between one and two years after cesarean section using high-resolution, three dimensional T2-weighted sampling perfection with application optimized contrast using different flip angle evolutions Magnetic Resonance Imaging (3D T2w SPACE MRI). Methods This prospective study was performed to investigate morphological changes in the cesarean scars and uterus from one to two years after cesarean section using high-resolution, 3D T2w SPACE MRI. The healthy volunteers having no childbearing history were recruited as the controls. All data were measured by two experienced radiologists. All data with normal distribution between the one-year and two-year groups were compared using a paired-sample t test or independent t test. Results Finally, 46 women took a pelvic MR examination one year after cesarean section, and a subset of 15 completed the same examination again after two years of cesarean section. Both the uterine length and the anterior wall thickness after two years of cesarean section (5.75 ± 0.46 and 1.45 ± 0.35 cm) were significantly greater than those measured at one year (5.33 ± 0.59 and 1.25 ± 0.27 cm) (t = -2.363 and -2.175, P= 0.033 and 0.048). No significant difference was shown in myometrial thickness two years after cesarean section (1.45 ± 0.35 cm) with respect to the control group (1.58 ± 0.21 cm, P = 0.170). Nine women who underwent MRI twice were considered to have scar diverticula one year after cesarean section, and still had diverticula two years after cesarean section. The thickness, height, and width of the uterine scar showed no significant change from one to two years (all P > 0.05). Conclusions 3D T2w SPACE MRI provides overall morphologic details and shows dynamic changes in the scar and the uterus between one and two years after cesarean section. Scar morphology after cesarean section reached relatively stable one year after cesarean section, and uterine morphology was closer to normal two years after cesarean section.

Through literature study,this paper summarizes the current status ofreseareh on the relationship between maternal exposure factors and small for gestational age infant both in China and abroad.And at the same time,the relationship between pregnancy outcome of small for gestational age and maternal exposure factors was analyzed.This might contribute to reduce the incidence of small for gestational age infant and provide important guidance and references for perinatal care.

Objective To access the current status of folic acid supplementation in women at childbearing age in suburban area of Beijing,2016.Methods In this cross-sectional study,a total of 722 women aged 17-41 years from six hospitals in suburban areas of Beijing were selected through cluster sampling.A questionnaire survey was conducted.Results The rates of folic acid intake and regular folic acid intake among women under survey were 63.9％ (456/714) and 83.3％ (380/456).In women who remembered the duration of folic acid supplementation,the overall rate of preconceptional folic acid supplementation was 35.5％ (159/450),in whom 27.3％ (123/450) began to take folic acid 0-3 months before pregnancy;8.0％ (36/450) began to take folic acid 3 months before pregnancy.Multivariate logistic regression analysis indicated that household registering type,preparation for pregnancy or pregnancy,parity,smoking and alcohol use were the influencing factors for folic acid supplementation.Conclusions The rate of folic acid supplementation remained low in childbearing aged women in suburban area of Beijing.It is necessary to further strengthen the health education about the importance of folic acid supplementation to improve the intake rate and the regular intake rate of folic acid in pregnant women and to promote maternal infant health and reduce the related complications.
