ObjectiveTo explore the therapeutic effects of different surgical strategies on women with mechanical valve dysfunction during pregnancy.MethodsA total of 11 patients with mechanical valve dysfunction during pregnancy who underwent surgeries in our hospital from 2007 to 2017 were retrospectively included. The average age was 27.5±3.7 years. The prognosis of patients was analyzed according to the gestational weeks, cardiac function and the severity of mechanical valve dysfunction.ResultsNo death occurred. Three of them suffered subtotal hysterectomy during the surgery because of uncontrolled bleeding, and the others recovered without complications. Among the 5 patients with pregnancies <28 weeks, 1 patient was found intrauterine death before hospital admission, 2 suffered fetal loss 5 days after the cardiac surgery, and the other 2 patients continued their gestations until deliveries. Among the other 6 patients with pregnancies >28 weeks, 1 fetus died because of intracranial hemorrhage, and the other 5 survived without embryopathy or foetopathy.ConclusionGestation week, cardiac function and severity of mechanical valve dysfunction may be taken into account when making a treatment regimen for women with dysfunctional valve prostheses during pregnancy.
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.

Methods Retrospective analysis was made on 131 FET cycles in 107 patients from March 2007 to August 2009. The relationship between pregnancy rate of FET and following factors were analyzed: age, the method of preparing uterus endometrium. Results ①There was no significant difference in pregnancy rate of FET among ＜29, 30 - 34, and ≥35 years old patients (45.28%, 37.88%, and 33.33%, respectively) (Pgt;0.05). ②There was no significant difference in patients’ age, the average embryo amount, embryo score, the cell amount in every embryo between the FET with hormone replacement therapy (HRT) and the FET with natural cycle (NC). The embryo implantation rate and pregnancy rate of FET with NC were lower significantly than those of FET with HRT (16.78% vs 29.21%; 29.51% vs 50.00%) (P＜0.05). Conclusion Age might not influence pregnancy rate of FET. FET with HRT has higher implantation rate and pregnancy rate than FET with NC.
Objective
To summarize the characteristics and management of pregnancy complicated with aortic dissection, and to explore the reasonable diagnosis and treatment plan.
Methods
The clinical data of 10 patients of pregnancy complicated with aortic dissection in Wuhan Tongji Hospital from January 2011 to June 2017 were collected. Their age was 25.2 (21-29) years.
Results
In the 10 patients, the majority (8 patients) were primipara, and most of them were in the late stages of pregnancy (5 patients) and puerperal (4 patients). Among them, 1 patient had gestational hypertension, and the blood pressure of the left and right upper extremities was significantly abnormal (initial blood pressure: left upper limb blood pressure: 90/60 mm Hg, right upper limb blood pressure: 150/90 mm Hg). The major clinical manifestations were severe chest and back pain which happened suddenly, with D-dimmer and C-creative protein increased which may be associated with inflammatory reaction. All patients were diagnosed by thoracoabdominal aortic CTA, including 5 patients of Stanford type A dissection and 5 patients of Stanford type B dissection. In the 10 patients, 1 patient refused surgery and eventually died of aortic rupture with the death of fetus before birth. And the remaining 9 patients underwent surgical treatment, 3 patients of endovascular graft exclusion for thoracic aortic stent graft, 2 patients underwent Bentall operation, 1 patient with Bentall + total aortic arch replacement + vascular thoracic aortic stent graft, 1 patient with Bentall operation combined with endovascular graft exclusion for thoracic aortic stent graft, 1 patient with Bentall + coronary artery bypass grafting, 1 patient of thoracoabdominal aortic vascular replacement. Among them, 1 patient underwent endovascular graft exclusion for thoracic aortic stent graft died of severe postoperative infection, and the remaining 8 patients were discharged from hospital. Nine patients were single birth, among them 5 newborn patients had severe asphyxia, 4 patients had mild asphyxia. Finally, 3 neonates died of severe complications, and the remaining 6 survived.
Conclusion
The ratio of pregnancy with Stanford type A aortic dissection is far higher than in the general population, the possibility of fetal intrauterine asphyxia is larger, but through active and effective surgical and perioperative treatment, we can effectively save the life of mother and fetus.
