OBJECTIVETo investigate the association between maternal serum neutrophil-lymphocyte ratio (NLR) and placental inflammatory response (PIR) in late pregnancy.

METHODSWe retrospectively analyzed the clinical and follow-up data of 478 pregnant women undergoing routine prenatal examination and delivery in our hospital in the year 2016. According to the placental pathological results, the women were divided into PIR group (238 cases) and control group (240 cases). The levels of serum inflammatory makers including leukocytes, neutrophils, lymphocytes, C-reactive protein (CRP) and NLR were compared between the two groups to analyze the association of these markers with PIR. Multivariate analysis was performed to identify the independent risk factors of PIR. Logistic regression model was established and the area under the receiver operating characteristic curve (ROC) was used for analyzing the prognostic value of these makers in late pregnancy.

RESULTSThe areas under the curve (AUC) of leukocytes, neutrophils, lymphocytes, CRP and NLR were 0.698 (95%: 0.485-0.766), 0.716 (95%: 0.453-0.783), 0.329 (95%: 0.228-0.431), 0.725 (95%: 0.677-0.765) and 0.801 (95%: 0.742-0.856), respectively. After adjusting the confounders, multivariate logistic regression analysis showed that preterm labor (OR=2.446, 95%: 1.003-4.590), premature rupture of membranes (OR=2.304, 95%: 1.049-4.161), NLR > 7 (OR=3.268, 95%: 2.071-6.920), and CRP > 15 mg/L (OR=2.137, 95%: 1.412-8.236) were independent risk factors for PIR.

CONCLUSIONSAn increased NLR in late pregnancy can serve as an effective indicator for predicting the risk of PIR.

Objective To analysis the common abnormalities in fetus with ventriculomegaly and clinical significance. Methods Collected from March 2010 to December 2016,298 cases of pregnant women whose fetus with ventriculomegaly and accepted the prenatal diagnosis of pregnancy,including 109 cases of isolated cerebral ventriculomegaly(IVM),and 189 cases of non-isolated cerebral ventriculomegaly(NIVM).They were divided into mild groups(10.0-11.9 mm),moderate group(12.0-14.9 mm)and severe group(≥15.0 mm)according to the width of the lateral ventricle. Results(1)The most common abnormality of the NIVM were neurodevelopmental system(37.30%,94/252);The second was ultrasonic soft index(27.78%,70/252).(2)The most frequent combi-nation in mild group was ultrasonographic soft mark anomalies(44.76%,47/105),followed by other ultrasonic indi-cators(18.10%,19/105).The abnormal incidence of central nervous system was higher in middle group(45.16%, 42/93),followed by ultrasonic soft index abnormality(21.51%,20/93).The abnormality of the central nervous sys-tem was 62.96%(34/54)in severe group,followed by an abnormal(14.81%,8/54).(3)There was a difference in the nervous system and the ultrasonic-soft indicator between the non-isolated lateral ventricle dilation with different lateral ventricle widths(P<0.001).There was no difference in cardiovascular abnormalities. Conclusion Prena-tal ultrasound revealed that fetus with cerebral ventriculomegaly should carefully examine whether other abnormali-ties existed to determine the prognosis of the fetus and whether intervention should be taken.There was a difference between the different types of lateral ventricle and the prognosis.

Objective The aim of this study was to investigate the association between maternal serum lev-el of neutrophil-lymphocyte ratio(NLR)and preterm labor in late stage of pregnancy. Methods In this retrospec-tive analysis of 200 pregnant women who underwent routine prenatal examination and delivered from January 12016 to December 312016 in the Maternal and Child Health family planning services,Xinhui District,Jiangmen city. The patients were divided into the PIR group(n = 100)and the control group(n = 100). The levels of leuko-cytes,neutrophils,lymphocytes,CRP and NLR of the two groups were compared. Multivariate analysis was per-formed to identify independent risk factor. Logistic regression model was established and the area under the receiver operating characteristic curve(ROC)was recorded for analysis of the prognostic value of different serum inflamma-tory makers in late stage of pregnancy. Results The NLR predict premature occurrence of AUC,the sensitivity and specificity of which were higher than those of peripheral blood leukocyte,neutrophil count,lymphocyte count and CRP. Conclusion Increased NLR in late stage of pregnancy could serve as an effective factor to predict the risk of preterm labor.

AIM: To investigate the expression and significance of MAPK-interacting kinase-2 ( Mnk2 ) and eukaryotic initiation factor 4E ( eIF4E) in the patients with resected esophageal squamous cell carcinoma ( ESCC ). METHODS:The protein expression of Mnk2 and eIF4E in ESCC tissues (98 cases) and normal esophageal tissues (20 cases) were assessed by immunohistochemistry (IHC), and their correlations with clinicopathological features were statisti-cally analyzed.RESULTS:The over-expression rate of Mnk2 and eIF4E was 68.4%(67/98) and 61.2%(60/98), re-spectively.The expression of Mnk2 had a positive correlation with eIF4E (P<0.05).Clinicopathologic analysis showed that Mnk2 expression was significantly correlated with T classification ( P<0.05 ) and clinical stage ( P<0.05 ) .CON-CLUSION:The over-expression of Mnk2 was significantly related to the tumor invasive depth , TNM stages and expression of eIF4E in ESCC.Expression of Mnk2 and eIF4E may have a cooperative formation mechanism in the development of ESCC.

Objective To obtain a more accurate assessment of prognostic significance of NLR in ovarian cancer. Methods A systematic literature search was conducted using the electronic databases PubMed ,Web of Science,and Embase up to May 2016. Hazard ratio(HR)and odds ratio(OR)with 95% confidence interval (95%CI)were calculated. Statistical analysis was performed using Stata 12.0. Results 12 studies,consisting of 3 ,854 patients ,were selected in this meta-analysis. High NLR level was significantly associated with poorer overall survival(OS)(HR:1.69)and shorter progression free survival(PFS)(HR 1.63). Additionally,increased NLR was significantly correlated with advanced FIGO stage(OR 2.32),higher level of CA-125(OR 3.33),more extensive ascites(OR 3.54)as well as less chemotheraputic response(OR 0.53). Conclusions Elevated pretreat-ment NLR can serve as a predicative factor of poor prognosis for ovarian cancer.

Objective To investigate the synergistic anticancer effect of ATO combined with Rad001 on human ovarian cancer cells in vitro and the underlying mechanisms. Methods SKOV3 cells were treated with Rad001, ATO and a combination of Rad001 and ATO, respectively. Cell relative luminescence units, viability, and combination index were tested. The apoptosis was quantified by Flow cytometry. Autophagy and apoptosis associated proteins were measured with immunoblotting. Results Significant decrease in live cell number were observed in cells treated with combination of Rad001 and ATO , compared with single compound treatment (P <0.05). Moreover, a higher rates of autophagy as well as apoptosis were observed in the combination treatment compared with single compound treatment (P < 0.05). Conclusions combination of Rad001 and ATO can result in synergistic cytotoxicity through activation of the excessive autophagy and apoptotic pathway.

Objective To analyze the GDM of 336 cases with chronic HBV in pregnancy. Methods According to HBV DNA≥1.0 × 103 IU/mL, participants were divided into HBV DNA (+) or (-) group. 409 cases without HBV were selected as control group. Differences on GMD incidence between groups and virus load and OGTT blood sugar correlation were compared. Results The incidence of GDM of HBV DNA (+) or (-) group was 16.77% and 17.71%, which is higher than that in HBV group (10.27%). The difference is significant (P < 0.05). The correlation index between HBV DNA and fasting blood-glucose is r = 0.005, P = 0.610, the result of which is not statistically significant. But correlation index between HBV DNA and blood sugar at 1 h , 2 h are r = 0.082, 0.086; P = 0.000, 0.000, the result of which is statistically significant. Conclusion The oc-currence of GDM were higher in HBV DNA (+) or (-) group. The viral load is positively related with blood sugar of glucose tolerance at 1 h or 2 h.

Objective To investigate the risk of postpartum haemorrhage in HBV-infected pregnant women. Methods Cohort or case-control studies that discussed the relationship between hepatitis b virus infection and pregnancy outcome were searched in PubMed , EMBASE , Wiley Online Library , Cochrane Library , Google Scholar, CBM, WanFang database and CNKI etc. (till August 2015). The quality of included Cohort or case-control studies was evaluated , and Meta-analysis was performed with Rev Man5.2 software. Results Four observational case-control studies and 17 cohort studies , involving 19 549 women in observation , were identifled. Meta-Analysis results displayed that the incidence of postpartum haemorrhage in HBV-infected women was 9.3%, while 2.8% in women without HBV [RR = 2.97, 95% CI (2.25 ~ 3.92),P < 0.01]. Compared with normal-risk women , the incidence of postpartum haemorrhage of HBV-infected women with normal hepatic function was also higher [RR = 2.56, 95% CI (2.01 ~ 3.25),P < 0.01]. HBV-infected women with hepatic dysfunction had higher incidence of postpartum haemorrhage than those with normal hepatic function [RR = 2.67, 95% CI (2.17~ 3.28),P < 0.01]. Conclusions HBV-infected women are at higher risk of postpartum haemorrhage than normal pregnancy women and further hepatic dysfunction would lead to a continuing increase of the risk.
