ABSTRACT
Objective:To determine the gestational weight gain and its risk factors and adverse effects among pregnant women in Beijing.Methods:Between June 2018 and June 2019, all registered infants and their mothers in a child care center of a third-tier-class hospital in Beijing were selected. A self-made questionnaire was used to collect the basic information of the maternal mothers. Chi-square test and analysis of variance were used to describe the basic characteristics of the study subjects and clarify the harmful effect of gestational weight gain for maternal and infant health. Multiple logistic regression analysis was used to analyze the risk factors of both insufficient and excessive weight gain during pregnancy.Results:A total of 3732 maternal mothers and their babies were included. The average weight gain of maternal mothers during pregnancy was 13.0 kg. The results of this study showed that the proportion of insufficient weight gain during pregnancy was 31.8% and the proportion of excessive weight gain was 24.1%. It was further found that young age, pre-pregnancy body mass index indicating overweight and obesity, primipara, and low education were independent risk factors for excessive weight gain during pregnancy. The risk of excessive weight gain of pre-pregnancy overweight and obesity was 2.40 times ( OR=2.40, 95% CI=1.91-3.03, P<0.001) and 2.90 times higher, respectively, ( OR=2.90, 95% CI=1.59-5.27, P<0.001) when compared with that of pre-pregnancy normal weight. In addition, our results suggested that excessive weight gain significantly increased the risk of macrosomia for the infant and the risk of cesarean section, gestational hypertension, and postpartum weight retention for maternal mothers. Conclusions:Age, pre-pregnancy BMI, primipara, and education level were the influencing factors for gestational weight gain. Considering the serious harmful effects of both insufficient and excessive weight gain for maternal and infant health, weight management during pregnancy should be strengthened for these high-risk populations in the future.

ABSTRACT
Objective To explore the value of ultrasound in the differential diagnosis of neonatal upper and lower gastrointestinal tract ( GIT) perforation. Methods We retrospectively reviewed the ultra-sound findings of 42 neonates of surgery-confirmed neonatal GIT perforation in our hospital from January 1, 2015 to December 31,2018. The accuracy of ultrasound for detecting GIT perforation and the ultrasound fea-tures of upper and lower GIT perforation were evaluated. Results (1)Of the 42 neonates with GIT perfora-tion,1 case didn′t undergo ultrasound,2 cases were missed,and 1 case was misdiagnosed. Thirty-eight neo-nates were diagnosed of GIT perforation by ultrasound preoperatively,with a detection rate of 92. 7%(38/41). The locations of GIT perforation were identified by ultrasound in 30 cases(78. 9%,30/38),including 11 cases of upper GIT perforation and 19 cases of lower GIT perforation. (2)A common sonographic finding of GIT perforation in 38 cases was pneumoperitoneum,which appeared as an echogenic line with posterior rever-beration artifact under diaphragm or anterior to hepatic/splenic surface and a "stratosphere" sign in M-mode sonography. Free gas changed position when the patient′s position was changed,and didn′t change due to re-spiratory change. Besides,free gas dispersed with compression on abdomen,and gathered without compres-sion. (3)Upper GIT perforation was showed that poor filling of the stomach cavity,and the abdominal free gas sharply increased. Lower GIT perforation was characterized by collapsed bowel,blurred and interrupted intestinal wall structure, and more accompanied with intestinal obstruction. ( 4 ) There was no significant difference of detection rate between ultrasound and X-ray in diagnosing GIT perforation [92. 7%(38/41) vs. 83. 3%(35/42)]( P>0. 05),whereas ultrasound more sensitive for a very small amount of free gas in the early stage of perforation. (5) Helicobacter pylori infection was found in two cases of GIT perforation. Conclusion Ultrasound can be used for differential diagnosis of upper and lower GIT perforation,and could be recommended as the first choice for detecting GIT perforation in neonatal patients.
