ObjectivesTo systematically review the perinatal outcomes after laparoscopic myomectomy versus transabdominal myomectomy.MethodsPubMed, Web of Science, Elsevier, The Cochrane Library, CNKI, VIP and WanFang Data databases were searched from inception to July 2017, to collect randomized controlled trials or cohort studies comparing the perinatal outcomes after laparoscopic myomectomy and transabdominal myomectomy. Two reviewers independently screened literature, extracted data and assessed the risk of bias of include studies. Meta-analysis was then performed by RevMan 5.3 software.ResultsEight randomized controlled trials, twenty-one cohort studies involving 4357 patients were included. The results of meta-analysis showed that: the premature birth rate (OR=0.60, 95%CI 0.38 to 0.95, P=0.03) in the laparoscopic myomectomy was lower than that in the laparotomy group. However, the rate of uterine rupture during pregnancy (OR=3.19, 95%CI 1.29 to 7.89, P=0.01) in the laparoscopic myomectomy was higher than that in the laparotomy group. There were no significant differences between two groups in the myoma residual (OR=1.00, 95%CI 0.37 to 2.65, P=0.99), recurrence (OR=0.92, 95%CI 0.68 to 1.25, P=0.60), abortion (OR=0.90, 95%CI 0.63 to 1.28, P=0.56), ectopic pregnancy (OR=1.11, 95%CI 0.54 to 2.26, P=0.78), pregnancy rate (OR=1.06, 95%CI 0.89 to 1.27, P=0.52), cesarean (OR=0.82, 95%CI 0.57 to 1.19, P=0.31), and pregnancy complications (OR=0.84, 95%CI 0.45 to 1.59, P=0.60).ConclusionsCurrent evidence shows that there are no significant differences between two groups in the myoma residual, myoma recurrence, abortion, ectopic pregnancy, pregnancy rate, cesarean and pregnancy complications. While the rate of uterine rupture during pregnancy in the laparoscopic myomectomy is higher than that in the laparotomy group, the premature birth rate after operation in the laparoscopic myomectomy is lower and shorter than that in the laparotomy group. Due to the limited quantity and quality of the included studies, more high quality studies are required to verify the above conclusion.
Objectives To investigate calcium supplement in pregnancy for prevention of preeclampsia and relevant outcomes. Methods The Cochrane Library, PubMed, EMbase, CBM, WanFang Data, VIP and CNKI databases were searched online to collect randomized controlled trials (RCTs) of calcium supplement in pregnancy for prevention of preeclampsia and relevant outcomes from inception to July 2018. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Meta-analysis was then performed by RevMan 5.3 software. Results A total of 33 RCTs involving 29 234 subjects were included. The results of meta-analysis showed that: compared with control group, the calcium supplement group was associated with lower preeclampsia (RR=0.48, 95%CI 0.38 to 0.62, P<0.000 01) and gestational hypertension (RR=0.65, 95%CI 0.55 to 0.77,P<0.000 01) incidence. The incidence of premature delivery, intrauterine growth retardation and severe preeclampsia in calcium supplement group was lower than that in placebo group, and the neonatal weight in calcium was higher than that in placebo group. However, there was no significant difference in the pregnancy cycle between the two groups. Conclusions Current evidence shows that calcium supplement is associated with lower risk of preeclampsia and gestational hypertension. Due to limited quality and quantity of the included studies, more high quality studies are required to verify the above conclusion.
ObjectiveTo establish a normal reference value range of specific thyroid function in pregnant women corresponding to Beckman reagent in Chengdu.MethodsWe randomly selected 120 non-pregnant women and 445 pregnant women who underwent routine examinations at the First Affiliated Hospital of Chengdu Medical College from November 2016 to June 2017; tested for free triiodothyronine (FT3), free thyroxine (FT4), and thyroid stimulating hormone (TSH) in serum; used SPSS 24.0 to calculate the bilateral limit of each index (Section 2.5, 97. 5 Quot); established the normal range of Beckman reagent.ResultsThe reference ranges of FT3, FT4, and TSH in the first, second, and third trimester of pregnancy were 4.41–6.33, 4.17–6.12, and 3.86–6.39 pmol/L; 7.64–14.63, 6.62–13.69, and 6.62–12.51 pmol/L; 0.21–3.62, 0.16–4.35, and 0.89–4.88 mU/L; respectively. There was no significant difference in serum TSH between the first and second trimester (P>0.05), and neither between the first and second trimesters and the controls in serum FT3 (P>0.05). The differences in serum FT3, FT4, and TSH among the rest of trimesters, and between each trimester and the normal control group were statistically significant (P<0.05). There was a significant correlation between TSH and FT4 in the early and middle stages of pregnancy (r=–0.277, –0.392, P<0.01).ConclusionThe reference value of FT3, FT4, and TSH in pregnant women with Beckman reagent was significantly different from that in non-pregnant women.
【Abstract】ObjectiveTo investigate the indications, maternal and fetal/neonatal risks and treatments of pregnancy after liver transplantation. Methods The related published literatures were summarized and reviewed.ResultsMost females can recover a regular menstrual cycle. Hypertension, preeclampsia, bacterial and viral infection resulted from immuno-suppression therapy and increasing rate of caesarian section are the major risks for the mother. Abortion and preterm delivery, premature rupture of fetal membrane, hypoadrenalism, abnormality, immune deficiency, hepatitis virus B and cytomegalovirus and bacterial infection are the major risks for the fetus/neonate.ConclusionSatisfactory results can be obtained in most pregnancies after liver transplantation. Evaluation before gestation and surveillance during gestation by the related departments are mandatory. A guideline based on large cases is necessary for pregnancy after liver transplantation.
Objective To analyze the clinical features and outcomes of pregnant women with acute diarrhea. Methods We collected the clinical data of 133 pregnant women with acute diarrhea (group A) admitted into Tangshan Maternal and Child Health Hospital and Kailuan General Hospital between June 2009 and June 2015. Another 100 acute diarrhea patients without pregnancy (group B) and 100 pregnant women without acute diarrhea (group C) were regarded as controls. All the patients’ medical history, symptoms and signs, laboratory examination results, diagnosis and treatment, termination of pregnancy and pregnancy outcomes were retrospectively analyzed. Results The average age of group A patients was (29.72±5.19) years old, and 83.46% of them came to hospital within 24 hours. There were significant differences in vomiting, abdominal pain, white blood cells, neutrophils, C-reactive protein, white blood cells in the feces, fibrinogen, prothrombin time, activated partial prothrombin time, thrombin time and the recovery time of the laboratory indicators between group A and group B (P<0.05). The neonatal weight of group A was lower than that of group C, and the difference was statistically significant (P<0.05). Regression analysis showed that hemoglobin and albumin had significant influence on acute diarrhea during pregnancy (P<0.05). Conclusion Pregnancy with acute diarrhea is a kind of severe obstetric complication, which may lead to adverse pregnancy.
Objective To study the influence of hyperlipemia on rats with acute pancreatits during pregnancy and its mechanism. Methods Seventy two pregnant Sprague-Dawley rats were randomly divided into the test group and the control group， and then they were fed with high fat diet and balanced diet for 16 days separately. Pregnant rats were given intraperitoneal injection with L-arginine for 2 times (one time is 250 mg/100 g, the other is 200 mg/100 g) at an interval of 1 h. The serum triglyceride (TG), serum amylase (AMS), and lipase (LPS) from blood samples were tested just after injection, and 12 h， 18 h， 24 h， 30 h and 48 h after injection respectively, and wet/dry ratio of pancreas were measured. The histopathological score of pancreatic tissue was evaluated based on microscopic changes, and the expression of TNF-α protein was determined by SP immunohistochemical technique. Results After the last injection, the level of TG in the test group was obviously higher than that in the control group in each time (P＜0.05). The peak values of AMS and LPS in the test group appeared at 24， 18 h respectively, while the peaks appeared at 30， 24 h in the control group, respectively, which were significantly lower than those in the test group (P＜0.05). Compared with the control group, the wet/dry ratio of pancreas in the test group increased at 12, 18 and 24 h after injection (P＜0.05); The pathological changes of pancreas in test group was more serious with higher histopathological score at 0, 12, 18 and 24 h (P＜0.05), and expression of the TNF-α protein was higher at 12, 18 and 24 h (P＜0.05), too. Conclusion Hyperlipemia can make L-arginine-induced-acute-pancreatitis during pregnancy earlier occur and lead to more serious injury in pancreas. This study demonstrates that hyperlipemia may be a high risk factor for acute pancreatitis during pregnancy, making a great amount of free fatty acid released from TG and up-regulated the expression of TNF-α.
ObjectiveSummary of Integrative traditional Chinese and Western medicine nursing management and their effects for acute pancreatitis in pregnancycare. MethodFrom January, 2010 to July, 2014, 17 patients of acute pancreatitis in pregnancy were retrospectively analyzed. The integrative traditional Chinese and Western medicine nursing management includes general nursing, critical care, Chinese medicine nursing [oral or nasogastric feeding of traditional Chinese medicine (TCM), TCM enema, Liuhedan abdominal external treatment, acupuncture care], puerperium care and discharge guidance. ResultsAll 17 patients using the integrative traditional Chinese and Western medicine nursing management were recovered from the attack of acute pancreatitis. Two out of 17 patients underwent cesarean delivery, 2 with natural birth during the course of acute pancreatitis and the rest 13 patients continued pregnancy. ConclusionsThe integrative traditional Chinese and Western medicine nursing management have certain advantages for managing acute pancreatitis in pregnancy, together with the maternal line puerperium care and healthy eating guidance can obtain satisfactory curative effects.
ObjectiveTo systematically review the association between maternal folate supplementation during pregnancy and the risk of autism spectrum disorder (ASD) in the offspring.MethodsPubMed, EMbase, Web of Science, The Cochrane Library, Scopus, CNKI, WanFang Data, VIP and CBM databases were electronically searched to collect case-control and cohort studies on the association between maternal folate supplementation during pregnancy and the risk of ASD in the offspring from inception to December 2020. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies. Meta-analysis was then performed using RevMan 5.3 and Stata 14.0 software.ResultsA total of 17 studies involving 10 812 cases and 876 241 controls were included. The results of meta-analysis showed that there was no significant association between maternal folate supplementation during pregnancy and the risk of ASD in the offspring in the total population. The subgroup analysis revealed that maternal folate supplementation during pregnancy was statistically associated with a reduced risk of ASD in the offspring in the Asian population (OR=0.71, 95%CI 0.53 to 0.96, P=0.03). However, there were no statistical correlations in European and American populations.ConclusionsCurrent evidence shows that maternal folate supplementation during pregnancy may reduce the risk of ASD in the offspring in the Asian population. Due to limited quality and quantity of the included studies, more high-quality studies are required to verify the above conclusions.
ObjectivesTo systematically review the association between pregnancy-induced hypertension (PIH) and preterm birth in mainland China.MethodsPubMed, The Cochrane Library, ScienceDirect, Web of Science, CBM, CNKI, WanFang Data and VIP databases were electronically searched to collect studies on the association between PIH and preterm birth in mainland China from January, 2007 to March, 2019. Two reviewers independently screened literature, extracted data and assessed risk of bias of included studies; then, meta-analysis was performed by using Stata 12.0 software.ResultsA total of 48 studies were included, involving 43 276 cases of premature birth, 527 995 cases of full-term control group, in which there were 3 446 cases of PIH in premature delivery, with a prevalence rate of 7.96%. There were 14 099 cases of PIH in the full-term control group, with a prevalence rate of 2.67%. The results of meta-analysis showed that PIH was associated with preterm birth (OR=3.27, 95%CI 2.64 to 4.05, P<0.001). The overall population attributable risk was 13.0%. Subgroup analysis was conducted for different study types, and the results were unaltered.ConclusionsThe current evidence shows that PIH is associated with preterm birth. During pregnancy, the management and intervention of pregnant females with gestational hypertension should be strengthened, and active treatment should be supervised to prevent the occurrence of premature birth.
ObjectiveTo explore the influence of treatment against syphilis on pregnancy outcome and neonatal prognosis. MethodsThe data of 5224 cases of pregnant women from January to December 2013 were analyzed. All the pregnant women were screened by toluidine red unheated serum test (TRUST) method. Then, T.pallidum passive partideag glutining assay (TPPA) was used to confirm those positive cases from TRUST. At last, 128 cases of syphilis in those pregnant women were confirmed. According to whether the pregnant women accepted antenatal examination and treatment, they were divided into treatment group and non-treatment group. The pregnancy outcome and neonatal prognosis of these two groups of women were then compared and analyzed. ResultsThe pregnancy outcome of these two groups had comparatively big difference, but without significant difference (χ2=3.34, P>0.05). The neonatal prognosis of the two groups was significantly different (χ2=9.14, P<0.05). Moreover, TPPA showed positive in all newborn infants, and TURST showed 85 positive cases. ConclusionEarly finding and treatment of pregnant women with syphilis by screening before pregnancy or during the early period of pregnancy can reduce abortion, stillbirth, fetal abnormalities, and the incidence of neonatal congenital syphilis.
