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.

Methods : Fifteen cases with cesarean scar pregnancy performed with uterine artery interventional therapy were retrospectively analyzed from July, 2006 to December, 2007 in our hospital. Results : All cases were treated successfully by uterine artery chemotherapy and embolism. All cases were embolized with gelatin sponge after chemotherapy, and eight with spring ring additionally. Vaginal bleedings were stopped after uterine artery embolization. Gestation sacculi deflated obviously. Serum human chorionic gonadotrophin descended dramatically. There was no severe vaginal bleeding by curettage after interventional therapy. The villi, decidua, or placental tissues were observed with degeneration and necrosis by pathology. Conclusion : Uterine artery chemotherapy and embolization was proved to be a safe and useful procedure for preventing and controlling vaginal bleeding, diminishing the risk of curettage and avoiding the loss of uterus.
ObjectiveThis study aims to compare different references for the fetal risk of drugs used in pregnancy to provide evidence for the safety of drug use in pregnancy.MethodsFour drug databases, including Lexicomp, Micromedex, TERIS, and Reprotox, as well as two books of drugs in pregnancy edited by Briggs and Schaefer, were searched. Descriptive analysis was performed regarding the definition of pregnancy recommendations and the specific content of medication.ResultsThe six references employed slightly different approaches to drugs in pregnancy, however, all of them included summaries of the risk in pregnancy, data of crossing the placenta, and human and animal data. The databases of Micromedex, TERIS, and a book edited by Briggs had their risk classification systems for drug use during pregnancy. For specific drugs, the summary of different information in pregnancy was different, the amount and content of listed evidence varied, and there was no evaluation of the quality and relevance of evidence among the references.ConclusionsThere is no consensus on the risk assessment of drugs in pregnancy. Risk classification systems for drugs in pregnancy are still an important method for determining the fetal risk of drugs. The existing references merely list studies of drugs in pregnancy, without comprehensive quality assessment. A methodological study of assessment of the risk of drugs in pregnancy is required.
Objective To discuss the characteristics of delivery and anesthesia management of pregnant women with moderate to severe scoliosis, and to summarize the anesthesia implementation strategies for pregnant women with scoliosis. Methods Pregnant women with moderate to severe scoliosis admitted to West China Second University Hospital, Sichuan University between January 2020 and January 2022 were retrospectively included. The demography information, delivery mode, anesthesia implementation plan and other relevant data of the women were analyzed. Results A total of 9 women with moderate to severe scoliosis were included, with an average age of 29.9 years. The median (lower quartile, upper quartile) of the Cobb angle of the women was 42° (35°, 54°). There were 5 women with moderate to severe impairment of lung ventilation function, 1 woman with grade Ⅲ heart function, and 8 women with comorbidities. Among the 8 women who underwent cesarean section, 3 underwent general anesthesia, 4 underwent epidural block, and 1 underwent local anesthesia with enhanced sedation. One woman who chose vaginal delivery underwent epidural labor analgesia. All women passed the surgery or delivery period safely, with 5 transferred to the intensive care unit for further treatment after surgery, and 4 safely returned to the ward after surgery. All women recovered and were discharged. Eight fetuses survived, and 1 fetus underwent lethal induced abortion. Conclusions Pregnant women with moderate to severe scoliosis during pregnancy have poor tolerance to vaginal delivery due to severe malformations and organ dysfunction, especially cardiopulmonary dysfunction. Most of them terminate pregnancy through cesarean section. When making anesthesia decisions, it is important to carefully consider the women’s own condition and surgical risks.
Objective To analyze the effectiveness of conservative medical treatments for ectopic pregnancy (EP): methotrexate (MTX) + mifepristone + Ectopic Pregnancy II decoction (EP-II) vs. methotrexate + mifepristone. Methods A total of 95 patients with EP in Shenzhen Shajing Affiliated Hospital of Guangzhou Medical University from January 2009 to January 2011 were randomly divided into two groups: 45 patients in the experimental group were treated with MTX, mifepristone and EP II decoction, while the other 50 patients in the control group were treated with MTX and mifepristone. The effectiveness of the two groups was analyzed with SPSS 13.0 software. Results There were significant differences in the time of serum β-HCG return to normal (16.13±8.13 ds vs. 22.05±7.15 ds, Plt;0.05), time of EP mass absorption (30.46±7.56 ds vs. 39.99±18.26 ds, Plt;0.05) and tubal patency rate (80% vs. 75%, Plt;0.05) between the two groups. But there were no significant differences in effective rate (95.56%, 43/45 vs. 94%, 47/50, χ2=0.0809, Pgt;0.05) and side effects. Conclusion The combination of methotrexate, mifepristone and EP II decoction for ectopic pregnancy is more effective than mifepristone and methotrexate in coordinately killing the embryo, shortening the time of serum β-HCG return to normal and the time of EP mass absorption, and improving the function of oviducts.
Hypertensive disorder of pregnancy (HDP) is a type of disease unique to women during pregnancy. The most common clinical types are gestational hypertension and preeclampsia, which seriously threaten the health of pregnant women and fetuses. At present, there are no established criteria for the prediction and prevention of HDP. In recent years, a large number of studies have been carried out on HDP around the world, and many studies have shown a close correlation between serum uric acid and HDP. This article reviews the results of existing literature, elucidates the relationship between serum uric acid and the pathogenesis of HDP, prediction of HDP occurrence and development, and adverse pregnancy outcomes.
ObjectivesTo systematically review the efficacy and safety of local endometrial mechanical stimulation in patients with recurrent embryo implantation failure in vitro fertilization.MethodsPubMed, EMbase, The Cochrane Library, CNKI, WanFang Data and VIP databases were electronically searched to collect clinical controlled studies on the efficacy and safety of local endometrial mechanical stimulation in patients with recurrent embryo implantation failure from inception to March 2018. Two reviewers independently screened literature, extracted data and assessed the risk of bias of included studies, then, meta-analysis was performed by using RevMan 5.3 software.ResultsA total of 10 studies, including 8 randomized controlled trials and 2 case-control studies, and involving 1 274 patients were included. The results of meta-analysis showed that: the clinical pregnancy rate of endometrial mechanical stimulation group was higher than that of control group (RR=1.40, 95%CI 1.04 to 1.89, P=0.03). However, no significant differences were found in implantation rate (RR=0.75, 95%CI 0.50 to 1.13, P=0.17), live births rate (RR=1.38, 95%CI 0.99 to 1.93, P=0.06), miscarriage rate (RR=0.83, 95%CI 0.55 to 1.24, P=0.36) and rate of multiple pregnancy (RR=0.90, 95%CI 0.61 to 1.35, P=0.63).ConclusionCurrent evidence shows that, for patients with repeated implantation failure, mechanical endometrial stimulation before re-transplantation may help to improve the clinical pregnancy rate of test-tube infants, however, it has no significant effects on implantation rate, live birth rate, abortion rate, multiple pregnancy rate and ectopic pregnancy rate. Due to limited quality and quantity of the included studies, more high quality studies are needed required to verify above conclusions.
ObjectiveTo observe the image characteristics of multispectral scanning laser imaging (MSLI) and OCT in patients with pregnancy induced hypertension syndrome (PIHS).MethodsA total of 112 patients (224 eyes) of PIHS patients diagnosed in Obstetrics Department of Tianjin First Central Hospital from May 2016 to May 2017 were included in this study. The average age of the patients was 27.00±2.14 years. The average course of the disease was 15.00±8.27 days. There were 174 eyes in 87 patients of blurred vision, dazzling and visual fatigue consciously. All patients performed BCVA, direct ophthalmoscope, B ultrasound, confocal scanning laser Ophthalmoscope (cSLO) and spectral-domain OCT (SD-OCT). SD-OCT was performed with Spectralis HRA+OCT from Heidelberg Company in Germany to acquire tomographic images. Using Herdelberg's colorful program (MultiColor) based on cSLO and operating in accordance with standard methods, one scan simultaneously obtained blue light reflection based on 488 nm, green light reflection based on 515 nm, and infrared reflection based on 820 nm, synthesis to MSLI. Fundus abnormalities were classified into arterial spasm (stage Ⅰ), arteriosclerosis (stage Ⅱ), and retinopathy (stage Ⅲ). OCT examination was divided into normal and abnormal cases according to the abnormality of retinal morphology and thickness.ResultsOf the 224 eyes, 68 eyes (30.36%) showed normal fundus examination and 156 eyes (69.64%) showed abnormal fundus performance. Among them, 28 eyes were stage Ⅰ (17.95%); 40 eyes were stage Ⅱ (25.64%); 88 eyes were stage Ⅲ (56.41%). Thirty-six eyes (16.07%) showed normal fundus and 188 eyes (83.93%) showed abnormal performance with OCT. Of the 188 eyes with abnormal fundus performance, 86 eyes (45.74%) had retinal neuroepithelial serous detachment; 56 eyes (29.79%) had RPE detachment; optic disc edema, bulge, and local reflexes in the retinal nerve fiber layer were enhanced and/or the thickness increased in 46 eyes (24.47%). In MSLI, 48 eyes (21.43%) showed normal fundus; 176 eyes (78.57%) showed abnormal performance. Retinal edema was showed in green on MSLI, serous retinal neuroepithelial layer detachment, RPE layer detachment, retinal nerve fiber layer thickening, accompanied by changes in local retinal structure. The higher the degree of bulge, the darker the color. Consistent with the range of retinal edema revealed by SD-OCT.ConclusionsMSLI and SD-OCT images show highly consistent lesions in PIHS patients. MSLI can more clearly show superficial and deep retinal lesions.
ObjectiveTo explored the influence of disease changes, weight gain, eosinophil levels and other factor in pregnancy women with asthma. MethodsCase records of gestational asthma patients produced in the obstetrics department of Peking University People's Hospital from October 2010 to October 2020 were collected, and refer to electronic medical records of clinics (pre-pregnancy and pregnancy). According to the disease control (asthma related unplanned respiratory clinics, emergency or hospitalization), patients were divided into pregnancy stable group and pregnancy fluctuation group. The basic characteristics, pre-pregnancy asthma control, weight gain during pregnancy and peripheral blood eosinophil level before labor were retrospectively analyzed. The cause of asthma attacks, clinical characteristics and distribution of gestational time in pregnancy fluctuations were described. Peripheral blood eosinophil levels in different period during pregnancy in the stable group were analyzed. ResultsTotally 124 cases of natural pregnancy singleton were enrolled in the study. The age was (32.3±3.9) years old. There were 71 patients in stable group and 53 patients in fluctuation group. The proportion of pre-pregnancy instability in the fluctuating pregnancy group was higher than that in the stable pregnancy group (P<0.05). The proportion of intermittent medication before pregnancy was higher in the fluctuating pregnancy group than in the stable pregnancy group (P<0.05). Peripheral blood eosinophil count before labor and the number of cases with eosinophil count≥0.15×109/L before labor were higher in the fluctuation group (all P<0.05). The proportion of hypertentive diseases in pregnancy and fetal distress in uterus were higher in the fluctuation group (all P<0.05). The common cold was the common trigger factor (38.2%) and asthma recurrences occur between 13 and 36 weeks of gestation (65.8%) in fluctuation group. In further analysis of subgroup (the stable group), peripheral blood eosinophil count in early pregnancy (P<0.05) and pregnant metaphase (P<0.05) were higher than before delivery. The number of cases with eosinophil count>0.15×109/L in pregnant metaphase (P<0.05) was higher than before delivery. ConclusionsAsthma fluctuates during pregnancy is associated with adverse maternal and fetal outcomes. It is very important and critical that asthma control before pregnancy, weight gain management and eosinophil level monitoring of patients with asthma during pregnancy. The whole management is imperative in women with asthma during pregnancy.
Objective To assess the effect of pregnant rat adipose-derived stem cells (ADSCs) on repair of acute liver injury. Methods ADSCs were isolated from 18-week pregnant Sprague Dawley rats and were identified by flow cytometry. Twenty Sprague Dawley rats were randomly divided into groups A, B, C, and D (n=5); rats in group A were not treated as normal controls; rats in groups B, C, and D were injected intraperitoneally with CCl4 to establish the acute liver injury model. At 2 hours after modeling, DPBS, 0.1 mL normal rat ADSCs (2×106cells/mL), and pregnant rat ADSCs (2×106cells/mL) were injected into the spleen in groups A, C, and D respectively; rats in group B was not treated. After 7 days, total bilirubin (TBIL), alanine aminotransferase (ALT), aspartic acid transaminase (AST), albumin (ALB), and total protein (TP) in serum were measured. The liver tissue sections were stained with HE. The expressions of Ki67, alpha-fetoprotein (AFP), and ALB were measured by immunohistochemistry. Results The serum levels of TBIL, ALT, and AST in group B were significantly higher than those in groups A, C, and D (P<0.05), but ALB and TP were significantly lower than those in groups A, C, and D (P<0.05). The levels of TBIL, ALT, and AST were significantly higher in groups C and D than group A, and in group C than group D (P<0.05). There was no significant difference in serum levels of ALB among groups A, C, and D (P>0.05). The serum level of TP in groups C and D was significantly lower than that in group A (P<0.05), but no significant difference was found between group C and group D (P>0.05). HE staining showed that the liver tissue of group A had clear structure; the cells arranged neatly with uniform size. The hepatocytes in group B showed obvious edema, disorderly arrangement, dot necrosis in liver lobules, and diffuse infiltration of inflammatory cells. In groups C and D, the inflammation and hepatocellular necrosis were obviously reduced when compared with group B, and the number of vacuoles caused by dilation of mitochondria and rough endoplasmic reticulum was decreased; especially in group D, improvement of liver injury was more effective. The Ki67 positive cell rate was significantly higher in groups C and D than groups A and B (P<0.05), in group B than group A (P<0.05), and in group D than group C (P<0.05). There was no expression of AFP in groups A and B, but positive expression was observed in groups C and D, and AFP positive cell rate of group D was significantly higher than that of group C (t=3.006,P=0.017). ALB expression was significantly higher in groups C and D than groups A and B (P<0.05), and in group D than group C (P<0.05). Conclusion Pregnant rat ADSCs could promote repair of liver injury induced by CCl4.
