Objective To analyze the infection of human parvovirus B19 among women of childbearing age in Xiangyang City, and to provide a reference for pregnant women's health care. Methods A total of 303 women of childbearing age in Xiangyang City from 2018 to 2019 were selected as the research subjects. B19 virus DNA in serum of the subjects was detected by nested PCR technology. The differences in the detection rate of B19 viral DNA among normal pregnancy, abnormal pregnancy, and infertility serum were statistically analyzed. The differences in the detection rate of B19 virus DNA among women of childbearing age at different ages were compared. Results The detection rate of B19 viral DNA in all 303 women of child-bearing age was 27.72%. The detection rate of B19 virus DNA in 26-35 year old women was higher than that in other age groups. The detection rate of B19 virus DNA in abnormal pregnancy group was significantly higher than that in normal pregnancy group (P <0.05). Conclusion The detection rate of B19 virus DNA in abnormal pregnancy and infertility group was significantly higher than that in normal pregnancy group, with the detection rate of B19 virus in 26-35 year old women of childbearing age being the highest among all age groups. It is necessary to strengthen the screening of B19 virus in pregnant women of childbearing age in this region to reduce its impact on fetal abortion.

Analysis of pregnancy outcomes in patients with uterine fibroids after high intensity focused ultrasound treatment / 中国实用妇科与产科杂志

OBJECTIVE: To investigate the effect of high intensity focused ultrasound(HIFU)on pregnancy outcomes inpatients with uterine fibroids.METHODS:From October 2010 to October 2017,241 patients with uterine fibroids whowere pregnant after HIFU treatment in Suining Central Hospital and Chongqing Haifu Hospital were retrospectivelyanalyzed.The efficacy of HIFU ablation and the patient′s pregnancy outcomes were investigated.RESULTS:Among thesepatients,9 of them were conceived within 2 month after HIFU,24 were conceived between 2 and 4 months after HIFU,33 patients were conceived between 4 and 6 months,and 175 patients were conceived after 6 months of HIFU treatment.The median conception time was 9 months after HIFU(range:1 to 26 months).Among them,152 patients had deliveredbabies successfully,12 patients are still in pregnancy,3 patients had ectopic pregnancy,2 patients had incisionalpregnancy,72 patients had abortions,including 66 cases of induced abortion and 6 cases of spontaneous abortion.Causesof induced abortion included:embryonic development stopping(8 cases),increased vaginal bleeding(5 cases),hypothyroidism(1 case),use of drugs during pregnancy and being fear of fetal malformation(6 cases),and unplannedpregnancy(52 cases).Of the 152 patients who had delivered,147 had 148 full-term deliveries(1 had full-term deliverytwice)and 5 had preterm birth.No uterine rupture occured during pregnancy or childbirth,and the newborn is healthy.Before HIFU treatment,136 of 241 patients had a history of abnormal pregnancy,and only 17 of these patients hadabnormal pregnancy after HIFU treatment.The incidence of spontaneous abortion in patients after HIFU treatment wassignificantly lower than before treatment(P<0.05).CONCLUSION:HIFU is a safe and effective treatment for patients whowish to have children.It can also improve the fertility of patients with a history of abnormal pregnancy,with no additionalobstetric risks.

Expression of adverse pregnancy in β-HCG,fβ-HCG doubling rate and progesterone levels / 中国基层医药

Objective To investigate the human chorionic gonadotropin (β-HCG) and its free β-subunit (fβ-HCG) content change,to observe the 48 hours multiplication factor,combined with progesterone value in the diagnosis of adverse pregnancy for clinical diagnosis and treatment of adverse pregnancy to provide guidance.Methods The chemiluminescence technique was used to detect serum β-HCG,fβ-HCG and progesterone levels in early adverse pregnancy.According to pregnancy,the pregnant women were divided into threatened abortion group (65 cases),missed abortion group (43 cases) and ectopic pregnancy group (62 cases),while 60 normal pregnant women were selected as control group.Theβ-HCG,fβ-HCG,progesterone levels and 48 hours multiplication factor were measured.The results combined with the pregnancy outcomes were analyzed.Results The serum β-HCG,fβ-HCG,progesterone levels in the threatened abortion group,missed abortion group and ectopic pregnancy group were (15 385 ± 4 350) IU/L,(77.2 ± 21.3) IU/L,(20.8 ± 6.3) μg/L; (1 584 ± 362) IU/L,(119.3 ± 34.1) IU/L,(6.1 ± 3.7) μg/L; (1 459 ± 493) IU/L,(132.1 ± 35.7) IU/L,(5.7 ± 3.4) μg/L; the β-HCG levels 48 hour doubling rates in three groups were (1.52 ±0.51),(0.21 ±0.26),(0.13 ±0.08) ;threatened abortion group β-HCG and 48 hours multiplication factor,progesterone levels and missed abortion and ectopic pregnancy group were significantly different (t =7.41,5.17,6.89,all P ＜ 0.05) ; there were no significant differences between missed abortion group and ectopic pregnancy group (t =0.851,0.782,0.864,all P ＞ 0.05) ;fβ-HCG in threatened abortion group was average 30mIU/mL lower than the missed abortion group and ectopic pregnancy group,the difference was statistically significant (t =6.18,P ＜ 0.05).With miscarriage success fβ-HCG showed a decreasing trend.Conclusion β-HCG and progesterone combined 48 hours multiphcation ratio values for monitoring miscarriage of important guiding significance for the diagnosis of missed abortion and ectopic pregnancy has important reference value trimester β-HCG 48 hour doubling rate of less than 0.5,abortion increased risk;fβ-HCG data descending indicates miscarriage treatment is effective.

Relationship between folic acid metabolism-related enzyme gene polymorphism and susceptibility of abnormal pregnancy / 重庆医学

Objective To analyze the relationship between methylenetetrahydrofolate reductase (MTHFR)C677T,A1298C and methionine synthase reductase(MTRR)gene polymorphism with abnormal pregnancy history.Methods 549 normal women (control group)and 300 women with the abnormal pregnancy history(observation group)were taken as the subjects by adopting the case control research method.The oral mucosa epithelial cells were collected for extracting genomic DNA.The MTHFR and MTRR gene polymorphisms were detected by the gene sequencing method.Results The distribution frequency of MTHFR 677TT genotype in the abnormal pregnancy group was significantly increased compared with the control group (10.00% vs.3.46%,χ2 =15.25,P <0.01);the distribution frequency of MTHFR-1298CC genotype in the abnormal pregnancy group was significantly in-creased compared with the control group (11.00 vs.4.01%,χ2 =15.66,P <0.01);the distribution frequency of MTRR A66G gen-otype had no statistical difference between the two groups(χ2 =3.02,P =0.082).The interactive analysis of 2 genes indicated that simultaneous carrying the MTHFR A1298C mutation site and MTRR A66G mutation site increased the possibility of abnormal pregnancy occurrence (OR=1.52,P =0.011).Conclusion MTHFR C677T and A1298C have a certain correlation with female ab-normal pregnancy occurrence.

Diagnóstico prénatal: retrospectiva / Diagnóstico prénatal: retrospectiva / Prenatal diagnosis: retrospective

O Diagnóstico Pré-Natal (DPN) é um conjunto de técnicas destinado a investigar a saúde fetal ainda no período de vida intrauterina. é dirigido principalmente a casais com risco aumentado de gerar uma criança com uma anomalia genética ou congenita. Seu objetivo fundamental pressupõe a identificação de anomalias cromossômicas, malformações, doenças metabólicas mendelianas e outras alterações circunstancialmente adquiridas durante a gestação e com repercussões sobre o feto (1-4). O DPN tem sido usado como um método formal de diagnóstico por mais de 45 anos, passando por diferentes fases no seu desenvolvimento. A história do DPN está relacionada com a introdução e o aprimoramento de novas técnicas laboratoriais e diagnósticas. O primeiro passo para o conhecimento do compartimento feto-placentário foi dado por Bevis, em 1952, quando realizou uma amniocentese com fins propedeuticos: o estudo da doença hemolítica fetal. Nos seguintes anos, vários pesquisadores demostraram que é possível determinar o sexo fetal mediante o estudo da cromatina sexual em células de líquido amniótico (5- 8). O desenvolvimento das técnicas cito-genéticas (9) levou a Fuchs e Philips (10) a demonstrar a viabilidade de se cultivar células obtidas no Líquido Amniótico (LA) para posterior análise do cariótipo fetal. Desse modo, obtiveramse os primeiros cariótipos fetais a partir de células de LA entre 1965 e 1967 (11-13). Valenti (14) e Nadler (15) descreveram o primeiro DPN de uma anomalia cromossômica: a trissomia do cromossomo 21. No mesmo ano, diagnosticouse uma anomalia por erro inato do metabolismo (galactosemia) mediante a análise do LA (15). Quatro anos depois, altas dosagens de alfafetoproteína (AFP) no soro materno foram correlacionadas com o aumento da probabilidade de ocorrencia de erros no fechamento do tubo neural (16).

El Diagnóstico Prenatal (DPN) es un conjunto de técnicas destinadas a establecer un diagnóstico fetal aún en el periodo de vida intra-uterina. Está dirigido principalmente a parejas con mayor riesgo de presentar un embarazo de un hijo con una anomalía genética o congénita. Su objetivo fundamental es lograr la identificación de anomalías cromosómicas, malformaciones, enfermedades metabólicas, mendelianas y otras alteraciones eventualmente adquiridas durante la gestación y con repercusiones sobre el feto. El DPN ha sido usado como un método formal de diagnóstico desde hace más de 45 años, pasando por las diferentes fases de su evolución. Esta revisión describe estas fases abordando las realizaciones científicas que permitieron su implementación y mejoramiento continuo.

Prenatal diagnosis is a set of techniques intended to establish a fetal diagnosis even in the period of intrauterine life. It is aimed primarily at couples with higher risk of having a genetic or congenital abnormal pregnancy. Its basic aim is to ensure the identification of chromosomal anomalies, malformations, metabolic and Mendelian diseases, and other alterations eventually acquired during pregnancy which have an impact on the fetus.Prenatal diagnosis has been used as a formal diagnosis method for more than 45 years, going through the various stages of its evolution. This text revises these phases by addressing the scientific and technological developments that have led to its implementation and continuous improvement.

Objective To understand the status of Toxoplasma gondii(TOX)infection in pregnant women in Qingdao area. Methods Antibody capture ELISA was used to detect the TOX-IgM,IgG and TOX-DNA in 1 341 pregnant women and 201 infer-tility,miscarriage,stillbirth pregnant women from June 2011 to July 2013. Results Among 201 abnormal pregnant women,43 cases were TOX antibody positive,accounting for 22.39%,and among the normal pregnant women,84 cases were TOX antibody positive,accounting for 6.26%,and there was a significant difference(χ2 =10.60,P<0.05). The TOX positive rate of 20-29 years old women was higher than that of the women aged over 30 years(χ2=21.9,P<0.05). The TOX antibody positive rates of families with pets and families without pets were 26.63%and 8.77%respectively(χ2=10.93,P<0.05). The TOX antibody posi-tive rates were 10.94%(22/201)in unemployed women,3.98%(8/201)in farmers,3.98%(8/201)in staff,and 3.48%(7/201)in workers. Conclusions The TOX infection rate in abnormal pregnant women is significantly higher than that in normal pregnancy women;therefore,the health education should be strengthened. In addition,in young women,especially 20-29 years old women, and some special occupation women,the control measures should be enhanced.

Effect of infection with Toxoplasma gondii on the complement regulatory proteins in the mouse placenta / 中华微生物学和免疫学杂志

Objective To investigate the expression of complement regulatory proteins on placentas of pregnant C57BL/6 mice infected with Toxoplasma gondii in order to explore the molecular immunological mechanism for abnormal pregnancy induced by T. gondii infection. Methods Twenty-four pregnant C57BL/6 mice were randomly divided into two groups equally. The infection group was intraperitoneally injected with 200 of living T, gondii RH strain tachyzoites on the 8th day of gestation, and the normal group of mice was injected with physiological saline. All mice were killed on day 14 after gestation and placentas were collected. The expression levels of Crry, GPI-DAF and CD59a mRNA were analyzed by real-time quantitative PCR, and the positive rates of Crry and GPI-DAF were measured with flow cytometry. Results The died fetus rates of infected group and control were 80. 95% and 4. 41% , respectively. The infected group was significantly higher than of that the control group (P＜0.01). The expression levels of Crry, GPT-DAF and CD59a mRNA in the infected and control group were 0.786 ±0. 199, 0.594 ±0.096, 0.880 ±0. 179 and 0.550 ±0.077, 0.221 ±0.074, 0.591 ± 0.075 , respectively, and the difference of three kind of complement regulation proteins between two groups was all significant (P＜0.01). The positive percentages of Crry and GPI-DAF cells of infected and control group were (10. 03 ± 2. 11) % , (2.95 ±1.04)% and (3. 15 ± 1. 32) % , (0. 66 ±0. 26) % , respectively, and the difference of the two kind complement regulation proteins between two groups was also significant ( P ＜ 0. 01). Conclusion The expression level of mouse placental complement regulatory proteins was increased after infection with T. gondii, and then immunological microenvironment at the fetomaternal interface was destroyed. It may be one of important immunological mechanism for abnormal pregnancy induced by T. gondii infection.

Clinical Outcomes of Increased Nuchal Translucency in Three Years / 대한산부인과학회잡지

OBJECTIVE: To evaluate the relationship between increased nuchal translucency (NT) and abnormal pregnancy outcomes. METHODS: From January 1999 to December 2001, The 298 fetuses of increased nuchal translucency (>or=2.5 mm) in period of 10-14 weeks gestation were reviewed retrospectively. Amniocentesis and high resolution ultrasonography during second trimester were done for all cases. We analyzed septation within NT, karyotypes, structural anomalies, and adverse pregnancy outcomes such as spontaneous abortion, intrauterine fetal death and preterm delivery. RESULTS: The mean age of the patients was 30.5 +/- 3.5 years. The mean gestational age and CRL were 12.5 +/- 0.95 weeks and 6.5 +/- 1.15 mm. We observed 18 (6%) cases of abnormal karyotypes. 7/46 (15.2%) fetuses with internal septation had abnormal karyotype and 11/252 (4.4%) fetuses without internal septation had abnormal karyotype (p=0.013). Among the 280 fetuses with normal karyotype, 8 (2.8%) fetuses had structural anomalies and 18 (6.4%) fetuses had adverse pregnancy outcomes. The chromosomal abnormality and structural anomaly were significantly increased in the group of nuchal translucency thickness above 3.5 mm (p=0.001). CONCLUSION: Increased nuchal translucency is related with chromosomal abnormality and abnormal pregnancy outcomes.

If you get pregnant in the 90s what are the chances that you will have a normal pregnancy and a normal baby?

What are the chances of a pregnant woman having a normal pregnancy and a normal baby in the 90s. This is an assessment after regionalization of perinatal care was established in Quezon City in 1986 through the setting up of a Q.C. Perinatal Council. The Council is composed of the Perinatal Center, Philippine Childrens Medical Center, Quezon City General Hospital, Veterans Memorial Medical Center and Quirino Memorial Medical Center. One thousand consecutive, unselected pregnancies were followed up from the first trimester until delivery. Eight hundred sixty eight (86.8%) had a normal pregnancy and baby; one hundred seven (10.7%) had premature deliveries. There were 4 stillbirths, 9 neonatal deaths and 18 NICU admissions. The perinatal mortality rate was 13 per 1000 pregnancies. There were 32 who developed hypertensive complications of pregnancy. Chance of developing a normal pregnancy is 6 out of 10, an abnormal pregnancy is 2 out of 10 and ending in an abortion is 2 per 100.
