ABSTRACT
Objective@#To analyze the status and related factors of adverse pregnancy outcomes in pregnant women with syphilis infection in Guangxi Zhuang Autonomous Region.@*Methods@#A total of 9378 pregnant women with syphilis infection who were diagnosed by Guangxi medical and health care institutions at all levels and were registered in the national "Management information system for mother-to-child transmission of AIDS, syphilis and hepatitis B" . The delivery date of these pregnant women were from 1 January 2014 to 31 December 2018, and their demographic characteristics, treatment, non-treponema pallidum titer, and pregnancy outcomes were collected. Multivariate logistic regression model was used to analyze the related factors of adverse pregnancy outcome.@*Results@#The age of the pregnant women with syphilitic infection was (30.05±6.07) years old. There were 1 184 cases with an adverse pregnancy outcome. The incidence of adverse pregnancy outcome was 12.63%, and 83.30% (7 812 cases) of patients received syphilis treatment, of which 50.32% (3 931 cases) were treated with standard treatment. The results of multivariate analysis showed that, the probability of an adverse pregnancy outcome for a 35-year-old was higher than those of the <25 year old [OR (95%CI)=1.37(1.13-1.67)]. The possibility of the occurrence of an adverse pregnancy outcome in 1-2 times of delivery was lower than that of 0 times of delivery in the past, with the OR (95%CI) value was 0.81 (0.70-0.94). Compared with those who tested for syphilis in the early stages of pregnancy, patients with gestational weeks ≥ 28 weeks of initial examination were more likely to have adverse pregnancy outcomes, with the OR (95%CI) value was 1.54 (1.26-1.88). Compared with the first test titer level was <1:8, the probability of an adverse pregnancy outcome was higher in the titer of ≥1:8, with the OR (95%CI) value was 1.33 (1.12-1.57). There was a higher probability of an adverse pregnancy outcome in the untreated patients compared to the treatment of the syphilitic, with the OR (95%CI) value was 1.41(1.19-1.68). Patients with unregulated treatment were more likely to have adverse pregnancy outcomes than those with standardized treatment, with the OR (95%CI) value was 1.27 (1.09-1.47).@*Conclusion@#Gestational weeks of first examination in pregnant women with syphilis infection, the first test titer, and the treatment condition were closely related to the occurrence of the adverse pregnancy outcome. Pregnant women with syphilis infection without treatment and unstandardized treatment were more likely to have adverse pregnancy outcomes than those of treatment and standardized treatment.
ABSTRACT
Objective To investigate the factors associated with the success rate of external cephalic version (ECV) for singleton and non-cephalic presentation pregnancies in the third trimester.Methods A retrospective study of ECV among singleton and non-cephalic presentation pregnant women in 36-40 weeks of gestation at Maternal and Child Health Hospital of Guangxi Zhuang Autonomous Region from January 2016 to June 2018 was analyzed.Results (1) Totally,251 cases of 358 pregnant women who underwent ECV were successful,with a total success rate of 70.1％ (251/358).The success rate of multipara was 79.1％ (129/163),while 62.6％ (122/195) in primipara (P＜0.01).The total vaginal delivery rate was 52.2％ (187/358),the vaginal delivery rate of multipara was 61.3％ (100/163),while 44.6％ (87/195) in primipara (P＜0.01).(2) Spontaneous reversion occurred in 7.6％(19/251) of ECV successful women,the rate of reversion of multipara was 10.9％ (14/129),higher than that of the primipara [4.1％ (5/122);P＜0.01].(3) Among the 232 pregnant women who did not reverted after successful ECV,187 cases of successful vaginal delivery,the vaginal delivery rate was 80.6％ (187/232);the vaginal delivery rate of the multipara was 87.0％(100/115),which was higher than that of the primipara [74.4％(87/117);P＜0.01].(4) The variables significantly associated with ECV success were parity,type of breech,whether fetal presentation was in pelvic or not (all P＜0.05).The complication rate was 2.2％ (8/358),among which the incidence of fetal distress,placental abruption and transient fetal heart abnormalities were 0.6％ (2/358),0.3％ (1/358) and 1.4％ (5/358) respectively.Conclusion By close monitoring,ECV is a safe and effective procedure in selected appropriate cases,and worthy of clinical application.
ABSTRACT
The aim of this article is to study the regulatory feedback loop between β-catenin and IQ motif containing GTPase activating protein 1 (IQGAP1), as well as the effect of this regulation loop in colon cancer cell proliferation. Western blot was used to detect the expression of IQGAP1 and β-catenin after changing their expression respectively by transfection in SW1116 cells. CCK-8 cell proliferation assay was used to detect the effect of IQGAP1 involved in the proliferation of SW1116 cells promoted by β-catenin. The results of Western blot indicated that β-catenin could positively regulate IQGAP1, while IQGAP1 silencing could up-regulate β-catenin, forming a negative feedback loop. The results of CCK-8 showed that IQGAP1 silencing inhibited β-catenin-mediated proliferation in SW1116 cells. In conclusion, our research reveals a negative regulatory feedback loop between β-catenin and IQGAP1 which has a remarkable effect on the proliferation ability of colon cancer cells.
ABSTRACT
Objective:The significant role of long non-coding RNAs (lncRNAs) in early diagnosis and predicting prognosis has been recognized in various cancers recently.However,the prognostic value of HOXA transcript at the distal tip (HOTTIP),a vital lncRNA in tumorigenesis,remains unclear.In this study,we evaluated its prognostic value by analyzing the correlation of HOTTIP expression with overall survival (OS),lymph node metastasis (LNM) and distant metastasis (DM) in different cancer types by meta-analysis.Methods:We performed a systematic search in PUBMED,MEDLINE,Web of Science and Cochrane Library update to November of 2016.A total of 604 patients from 6 studies were included in final analysis and went through a quantitative meta-analysis by Review manager 5.3.Results:We demonstrated that high expression of HOTTIP had a significant correlation with poor OS (hazard ratio [HR] =2.37,95％ confidence interval [CI] =1.81-3.10,p＜0.001),high LNM rate (odds ratio [OR]=2.29,95％CI=1.54-3.40,p＜0.001) as well as more DM occurrence (OR=3.30,95％CI=1.78-6.12,p＜0.001).Conclusion:Our results indicated that long non-coding RNA HOTTIP may serve as a potential prognostic biomarker in cancer progression.
