Objective To investigate the risk factors of reversible posterior leukoencephalopathy syndrome (RPLS) in pre-eclampsia or eclampsia gravida. Methods This study was conducted in the Third Affiliated Hospital of Guangzhou Medical University between January 2013 and March 2016. A total of 100 patients who had no severe neurological diseases and were diagnosed pre-eclampsia or eclampsia, and underwent brain MRI were collected retrospectively. They were divided into 2 groups according to the MRI results, the RPLS group (n=49) and the non-RPLS group (n=51). The medical history, clinical symptoms and the results of laboratory examination were analyzed by the logistic regression, in order to explore the risk factors.Results In single factor analysis, HELLP syndrome, pregnancy associated with other diseases, poor prenatal care, grade 3 hypertension, elevated systolic blood pressure or diastolic blood pressure, elevated WBC, aspartate transaminase (AST), alanine aminotransferase (ALT), uric acid (UA) and lactate dehydrogenase (LDH), decreased platelet (PLT), headache, visual changes, seizures and conscious disturbance were more frequent in the RPLS group than those in the non-RPLS group (all P<0.05). According to the multivariate logistic regression analysis, the elevated WBC (OR=1.291, 95%CI:1.058-1.575, P=0.012), UA (OR=1.008,95%CI:1.001-1.016,P=0.032) and headache (OR=18.260, 95%CI:3.562- 93.607, P=0.000) were the independent risk factors.Conclusions Maternal history, clinical symptoms and some laboratory examinations might help in the early diagnosis of RPLS in pre-eclampsia or eclampsia gravida. Headache, the elevation of WBC and UA were the most significant factors.

plus stented elephant trunk implantation (Bentall+Sun′s surgery), aortic root replacement (Bentall surgery), stent implantation, thoracic and abdominal aorta replacement. The aortic operation time of the 19 patients were 5 gestational weeks to 1 month after delivery. The relation between aortic operation and the termination of pregnancy: 4 patients underwent aorta surgery after termination of pregnancy, 9 patients had cesarean section and aorta surgery at the same time, 6 patients underwent aorta surgery before cesarean section. ②5 patients did not receive arota surgery, 2 patients of type A dissection and 1 patient of type B dissection died before the surgery;2 cases of type B dissection underwent conservative treatment. The termination time of pregnancy was 6-37 gestational weeks, with the average of (26 ± 10) weeks. (3)Maternal and fetal outcomes:20 patients survived after treatment (83%,20/24) and 4 patients died (17%,4/24). 10 cases were live births, including 4 full-term infants and 6 preterm premature infants. The birth weight of the neonates was 1 080-3 800 g, with the average of (2 302±764) g. Three of them were very low birth weight infants and 1 was low birth weight infant;3 neonates had mild asphyxia. The neonates were followed up for 0.5 to 10 years, with the average time of (1.4 ± 1.7) years. So far the infants′ development was good.Conclusions Pregnancy with aortic dissection is pernicious. Early identification, prompt diagnosis and prompt interventing of the vascular surgery are necessary to the safety of mother and fetus.

Objective To estimate the expression of ER and PR in the endometrium of both intrauterine adhesions (IUA) and non-IUA specimens. Methods The endometrium specimens from patients undergoing hysteroscopy for confirmed moderate IUA (n=20: 10 in proliferative phase, and 10 in secretory phase) were enrolled as the IUA group in Beijing Obstetrics and Gynecology Hospital from October 2014 to August 2015. The specimens scheduled for hysteroscopy due to infertility were recruited into the control group (n=26: 13 in proliferative phase, and 13 in secretory phase). Immunohistochemistry and quantificational real-time PCR (qRT-PCR) were used to detect the expression of ER-α, ER-β and PR in endometrium with different menstrual period in both groups. Results (1) Location: in both groups, the expression of ER-α, ER-β and PR appeared in the endometrial glandular epithelial cells and the stromal cells of the endometrium. The positive brown granules of ER-α, ER-β and PR appeared mainly in cell nucleus. (2) ER-α and ER-β in the endometrium:the protein expression of ER-α and ER-β in IUA group (proliferative phase: 0.657 ± 0.028, 0.493 ± 0.023; secretory phase: 0.537 ± 0.020, 0.365 ± 0.031) were significantly higher than those of control group (proliferative phase: 0.586 ± 0.025, 0.437 ± 0.022; secretory phase:0.459 ± 0.025, 0.323 ± 0.017;all P<0.01). And the ER-αand ER-βmRNA expressions in IUA group were 2.524 ± 0.296, 1.947 ± 0.339, higher than those of control group in the proliferative phase (all P<0.01), and in the secretory phase (1.977±0.333, 1.345±0.292) were also higher than those in the control group (all P<0.01). (3) PR in the endometrium: the protein expression of PR was not significantly different between IUA group (proliferative phase:0.248±0.025, secretory phase:0.194±0.024) and control group (proliferative phase: 0.234 ± 0.019, secretory phase: 0.186 ± 0.020; P=0.162, 0.359). Meanwhile, there were no statistical differences in the mRNA expression of PR in both groups with different menstrual period (proliferative phase: 1.144 ± 0.384 versus 0.981 ± 0.306, secretory phase: 0.763 ± 0.237 versus 0.631 ± 0.203; P=0.270, 0.166). (4) ER and PR expression in menstrual cycles: the expression of ER-α, ER-β and PR in the IUA group changed with the menstrual cycles, and their expression in the proliferative phase were higher than those in the secretory phase (all P<0.05). Conclusions The expression of ER-α and ER-β in the endometrium of IUA patients changes with menstrual cycle, and are higher compared with those in normal endometrium. No difference is found in the PR expression between the two groups.

Objective To investigate the mutations of BRCA genes in sporadic high grade serous ovarian cancer (HGSOC) and study its clinical significance. Methods Sixty-eight patients between January 2015 and January 2016 from the Affiliated Cancer Hospital of Zhengzhou University were collected who were based on pathological diagnosis of ovarian cancer and had no reported family history, and all patients firstly hospitalized were untreated in other hospitals before. (1)The BRCA genes were detected by next-generation sequencing (NGS) method. (2)The serum tumor markers included carcinoembryonic antigen (CEA), CA125, CA199, and human epididymis protein 4 (HE4) were detected by the chemiluminescence methods, and their correlation was analyzed by Pearson linear correlation. Descriptive statistics and comparisons were performed using two-tailed t-tests, Pearson′s chi square test, Fisher′s exact tests or logistic regression analysis as appropriate to research the clinicopathologic features associated with BRCA mutations, including age, International Federation of Gynecology and Obstetrics(FIGO)stage, platinum-based chemotherapy sensitivity, distant metastases, serum tumor markers (STM). Results (1) Fifteen cases (22%, 15/68) BRCA mutations were identified (BRCA1: 11 cases; BRCA2: 4 cases), and four novel mutations were observed. (2) The levels of CEA, CA199, and HE4 were lower in BRCA mutations compared to that in control group, while no significant differences were found (P>0.05), but the level of CA125 was much higher in BRCA mutation group than that in controls (t=-3.536,P=0.003). Further linear regression analysis found that there was a significant linear correlation between CA125 and HE4 group (r=0.494,P<0.01), and the same correlation as CEA and CA199 group (r=0.897,P<0.01). (3) Single factor analysis showed that no significant differences were observed in onset age, FIGO stage, distant metastasis, and STM between BRCA+and BRCA- group (P>0.05), while significant differences were found in CA125 and sensitivity to platinum-based chemotherapy between the patients with BRCA mutation and wild type (P<0.05). The multiple factors analysis showed that the high level of CA125 was a independent risk factor of BRCA mutations in sporadic HGSOC (P=0.007). Conclusion The combination of CA125 with BRCA have great clinical significance, the mutation of BRCA gene could guild the clinical chemotherapy regiments.

Objective To compare the clinical and histological features and prognosis of patients with ovarian cancer from different genetic background, and to make further understanding of the genetic model of BRCA genes used pedigree analysis. Methods There were 71 patients from 67 independent families enrolled in our study from Apr. 2000 to Jun. 2009 in Peking Union Medical College Hospital. All exons of BRCA1/2 genes were analyzed using denaturing high-performance liquid chromatography(DHPLC) followed by direct sequencing, and clinical features of patients were compared by statistical analysis. Pedigree analysis of two families with BRCA genes mutation were performed. Results The mutation rate of BRCA genes was 28%(20/71). The frequency of BRCA1 and BRCA2 gene mutation was 23%(16/71) and 6%(4/71), respectively (P=0.004). Histology types of patients with and without BRCA genes mutation were different. The onset age between patients with and without BRCA genes mutation was similar (52.6 versus 54.6 years old, P=0.393), and tend to be early-onset breast or ovarian cancer in high-risk group. There was no significant difference of platinum-resistant rate, disease free survival and overall survival rate between patients with and without BRCA genes mutation (all P>0.05). According to the pedigree analysis, up to 100% of female offspring inherited pathogenic mutations, and male offspring could be a mutation carrier. Conclusions The genetic screening and clinical intervention should be performed as early as possible for the members from families at risk of hereditary ovarian cancer. Genetic consulting is important for patients with high-grade papillary serous adenocarcinoma of ovary. It is still unknown that whether the patients with BRCA gene mutations have better prognosis than sporadic ones, and further perspective, randomized controlled trial is still needed.

Combined detection six biomarkers to diagnose serous and mucinous ovarian tumors is better than that of CA125.

Objective To analyze the variations of PTPS gene in patients with suspected 6-pyruvoyl-tetra hydropterin synthase deficiency (PTPSD) and to make prenatal diagnosis in high-risk families. Methods Chemiluminescence was used for phenylalanine detection in blood or dried blood spots.Patients with phenylalanine concentration over 120μmol/L were detected by urine pterin analysis, and the activity of dihydropteridine reductase (DHPR) was detected. tetrahydrobiopterin loading tests were performed in suspected patients with abnormal urinary pterin profiles. PTPS gene variation analysis was performed by direct Sanger sequencing based on PCR amplification. Prenatal diagnosis in 7 high-risk families was performed by chorionic villus sampling when the genotype was identified. Results In 656 patients with hyperphenylalanine, 22 cases were diagnosed as PTPSD clinically. 16 variations were detected in the 22 PTPSD cases. The 5 variations, p.Lys77Arg, p.Ile84Phe, c.315-2A>G, c.244-2A>T, c.187-1G>T, were identified as novel variations. Two fetuses carried the same mutation with the proband and therefore were thought to be PTPSD fetuses. Three fetuses carried only one mutant allele and thus were thought to be PTPSD carriers.

Objective To explore the expression of Ras-related protein 11(Rab11)in hypoxia, the effect of Rab11 on the invasion and migration of cervical cancer cell line SiHa and its possible mechanism. Methods SiHa cells were divided into 4 groups, the normoxic blank group (normal culture in normoxia), the hypoxic blank group (normal culture in hypoxia), the negative control group [transfection of negative control small interfering RNA(siRNA)in hypoxia], the Rab11-siRNA group (transfection of Rab11 siRNA in hypoxia). Western blot was used to examine the expression of Rab11, integrin α5, integrin β3, phosphorylated focal adhesion kinase(p-FAK), phosphorylated phosphatidylinositol 3 kinase(p-PI3K) protein, together with the expression of Ras correlative C3 creotoxin substrate 1(Rac1), which was critical in regulating cell invasion. The mRNA expression of Rab11 in the 4 groups was detected by realtime-qPCR. The cell invasion was detected by matrigel assay, while the cell migration was detected by transwell assay. Immunofluorescence was used to identify intracellular location of Rac1 in SiHa cell. Results (1) The expression of Rab11, intergrin α5, intergrin β3, p-FAK, p-PI3K and Rac1 in the normoxic blank group were 0.56±0.04, 0.33±0.03, 0.32±0.03, 0.36±0.03, 0.35±0.03 and 0.47±0.03, respectively. In the hypoxic blank group, they were 0.73±0.03, 0.74±0.03, 0.61±0.03, 0.62±0.03, 0.60±0.03 and 0.73±0.03, respectively. In the negative control group, their expressions were 0.72±0.03, 0.73±0.03, 0.59±0.03, 0.61±0.03, 0.59±0.03 and 0.72±0.03, respectively. While in the Rab11-siRNA group, they were 0.44±0.03, 0.30±0.03, 0.29±0.03, 0.30±0.03, 0.30±0.03 and 0.34±0.04, respectively. The expressions of Rab11, α5, β3, p-FAK, p-PI3K and Rac1 were significantly higher in the hypoxic blank group than in the normoxic blank group(P<0.05), and were significantly lower in the Rab11-siRNA group than in the hypoxic blank group and the negative control group(P<0.05). (2) The expressions of Rab11-mRNA were 1.000±0.000, 1.454±0.114, 1.442±0.101, 0.570± 0.046 in the normoxic blank group, the hypoxic blank group, the negative control group and the Rab11- siRNA group, respectively. It was significantly higher in the hypoxic blank group than in the normoxic blank group(P<0.05), and was significantly lower in the Rab11-siRNA group than in the hypoxic blank group and the negative control group(P<0.05). (3) By Matrigel, the invasion cell number in the normoxic blank group, the hypoxic blank group,the negative control group and the Rab11-siRNA group were 65±12, 106±16, 104± 17 and 50±11, respectively. The invasion capacity was significantly higher in the hypoxic blank group than in the normoxic blank group(P<0.05), and was significantly lower in the Rab11- siRNA group than in the hypoxic blank group and the negative control group(P<0.05). (4) By transwell assay, the migration cells in the normoxic blank group, the hypoxic blank group, the negative control group and the Rab11-siRNA group were 127±12, 169±15, 161±13 and 77±13, respectively. The capacity of invasion was significantly higher in the hypoxic blank group than in the normoxic blank group(P<0.05), and was significantly lower in the Rab11- siRNA group than in the hypoxic blank group and the negative control group(P<0.05). (5) The immunofluorescence showed that the red fluorescence intensity around nucleus was significantly increased in the normoxic blank group, the hypoxic blank group and the negative control group than in the Rab11- siRNA group. Conclusions Hypoxia could promote the invasion and migration of SiHa cells. In hypoxia, the down regulation of Rab11 expression could inhibit the invasion and migration of SiHa cells. This might be due to the decreased expression of the intergrin α5, intergrin β3, p-FAK, p-PI3K and Rac1 protein.

Objective To investigate the expression of long intergenic non-protein coding RNA-regulator of reprogramming (Linc-ROR) in high-grade ovarian serous cancer, and explore the relationship between Linc-ROR expression and biological function of high-grade ovarian serous cancer. Methods A total of 34 high-grade ovarian serous cancer tissue samples and 19 normal fallopian tube tissue samples were collected between June 2014 and February 2016. Real-time reverse transcription (RT)-PCR was used to detect the Linc-ROR mRNA expression in different samples. The relationship between Linc-ROR expression level and ovarian cancer International Federation of Gynecology and Obstetrics (FIGO) stage, lymph node metastasis was analyzed. Constructed Linc-ROR small interference RNA (siRNA) and pIRES2-EGFP-Linc-ROR plasmid, then Linc-ROR siRNA and pIRES2-EGFP-Linc-ROR plasmid were respectively transfected into SKOV3 cells. Cell proliferation, migration and invasion ability were assessed by cell counting kit-8 (CCK-8), wound healing assay and transwell invasion assay. Results (1) The expression level of Linc-ROR mRNA was significantly higher in high-grade ovarian serous cancer than normal fallopian tube tissues (4.31± 0.38 vs 1.03 ± 0.21; t=25.842, P<0.01). With the progression of FIGO stages, the expression of Linc-ROR was increased (F=95.702, P<0.01), and it was associated with lymph node metastasis (t=7.397, P<0.01). (2) The results of RT-PCR showed that the expression level of linc-ROR in Linc-ROR-i group was significantly lower than that in Linc-ROR-NC-i group (0.30 ± 0.11 vs 1.02 ± 0.10; t=15.269, P<0.01). The expression level in Linc-ROR-p group was significantly higher than that in Linc-ROR-NC-p group (8.90 ± 0.45 vs 1.03 ± 0.17;t=21.934, P<0.01). The CCK-8 assay showed that when the cells were cultured for 3, 4, 5 and 6 days, the A value in Linc-ROR-i group was significantly lower than that in Linc-ROR-NC-i group (P<0.05). And the A value in Linc-ROR-p group was significantly higher than that in Linc-ROR-NC-p group (P<0.05). Wound healing assay showed that, after 48 hours incubation, migration rate of cells in Linc-ROR-i group was significantly less than that in the Linc-ROR-NC-i group [(52±4)%vs(67±5)%;t=5.720,P<0.01]. The migration of cells in Linc-ROR-p group was significantly greater than that in the Linc-ROR-NC-p group [(84±4)%vs(66±4)%;t=7.330,P<0.01]. Cell transwell invasion assay showed that, after 48 hours of incubation, the number of invasive cells in Linc-ROR-i group was lower than that in Linc-ROR-NC-i group (74 ± 3 vs 104 ± 3; t=15.810,P<0.01). And the number of invasive cells in Linc-ROR-p group was higher than that in Linc-ROR-NC-p group (217 ± 4 vs 108 ± 5; t=38.060, P<0.01). Conclusion Highly expressed Linc-ROR could enhance the proliferation, migration and invasion ability of high-grade ovarian serous cancer cells, which may be one of the important molecules in the occurrence and development, invasion and metastasis of high-grade ovarian serous cancer.

Objective To estimate the prevalence and associated factors of adult female urinary incontinence in Hebei province. Methods Stratified and multistage sampling method was used, between January 2016 to May 2016, to investigate the target population in Hebei province. While, logistic regression was used to analyse datas. Results A population-based survey was conducted in 2 450 women in Hebei province, there were 2 408 effective questionnaires after deleting 48 invalid questionnaires. According to the results, the average age of subjects was (56±15) years old, and the urinary incontinence prevalence of adult female in Hebei province was 27.70%(667/2 408). Stress urinary incontinence, urge urinary incontinence and mixed urinary incontinence were diagnosed as 23.13%(557/2 408), 1.58%(38/2 408) and 2.99%(72/2 408), respectively. There were only 2.85% (19/667) urinary incontinence patients seeking medical help. The results of logistic regression analysis showed that age, daily water intake, pulmonary diseases, urinary tract infection, hypertension, chronic low back pain, dysmenorrhea, vaginitis, abortion, mode of delivery, postpartum infection were statistically significant (all P≤0.05). Among these factors, cesarean section was the protective factor for urinary incontinence (OR=0.365, 95%CI: 0.195-0.685, P<0.01). Conclusions The prevalence of urinary incontinence in adult female in Hebei province is high, and there are few patients seeking medical help. It is a common disorder in women and is associated with many factors;among these factors, cesarean section is the protective factor for urinary incontinence.
