Objective To explore the relative factors of polycystic ovarian syndrome (PCOS) in infertile women.Methods Ninety-eight infertile women diagnosed PCOS at affiliated hospital of the Chinese People's Armed Force Logistic college from Jan.2008 to Dec.2012 were served as PCOS group.Two hundred and eighty infertile women with normal ovarian structure according to laparoscopic examination result were selected as control group.The general information,factors related infertile and laparoscopic examination of the two groups were recorded.Results Fifty-one cases (52.0%) in PCOS group were with menarche age earlier than 13 years old,higher than that of control group (113 (40.4%),x2 =4.03,P < 0.05).Eleven cases (11.2%) in PCOS group were with abnormal menstruation cycle,higher than that of control group (12 (4.3%),x2 =6.12,P < 0.05).The incidence of pelvic adhesions in PCOS group was lower than the control group(60(21.1%) vs.224(40.4%),x2 =13.70,P <0.05).Irregular menstruation cycle was risk factor of PCOS (OR=1.770,95% CI:1.09-2.88,P =0.002).Conclusion Women with earlier menarche and irregular menstruation cycle should be paid more attention in terms of PCOS,early screening,discovery,prevention and treatment,so as to reduce the incidence of PCOS induced infertility and the long-term complications.

Objective To investigate relations between villus Benzo (a)pyrene (BaP)-DNA adducts and blighted ovum in early pregnancy, and to explore possible environmental factors influencing embryo development. Methods One hundred and two pregnant women with blighted ovum were selected into this study as research group; and 102 normal pregnant women were taken as control group; the age, gravidity, parity and gestational weeks of the two groups were matched. After artificial abortion, villi of the patients were collected and washed by normal saline. Then, the tissue was homogenated and genome DNA was extracted to detect quantity of the tissue. BaP-DNA adducts levels were examined by high-performance liquid chromatography-fluorescence method (HPLC). The personal information of pregnant women was collected by questionnaire. Logistic regression model was used to investigate the association between BaP-DNA adducts and blighted ovum. Results BaP-DNA adducts level in villi of research group [(8. 9±8. 2) adducts/108 nucleotides] was significantly higher than that of control group [(2. 0±1. 4) adducts/108 nucleotides], P<0.05. The higher the BaP-DNA adducts in villi, the higher risk the blighted ovum; when the BaP-DNA adducts level increased to 6.06 adducts/108 nucleotides, the risk of blighted ovum might increase 59.39 times (95% CI:15.50-227.55). Maternal education level was a protective factor (OR=-0.21, 95%CI:-0. 19--0.03) after controlling potential confounders. Conclusions High level of villi BaP-DNA adducts might increase the risk of blighted ovum in early pregnancy, and could have an adverse effect on embryo development.

Objective To investigate factors with pelvic adhesions and the effect of different degrees pelvic adhesions on fallopian tube recanalization in infertile patients.Methods Total of 527 infertile patients undergoing hysteroscopy and laparoscopic surgery in Affiliated Hospital of Chinese People's Armed Police Forccs Logistics College were studied retrospectively.According to the extent of pelvic adhesions,tubal umbrella adhesions and atresia,377 cases were classified into adhesion groups,including 73 cases in grade Ⅰ,221 cases in grade Ⅱ,75 cases in grade Ⅲ and 8 cases in grade Ⅳ based on adhesion score.The 150 cases with no obvious pelvic adhesion were matched as control group.Among 8 cases with grade Ⅳ ahesion were exluded from ahesion group the relationship between pelvic adhesions and related history,abdominal lesions,tubal patency and the prognosis were studied.Results(1)Related factors:the frequency of pelvic adhesion and more than 7 years of infertility of 23.9%(88/369)in adhesion group were significantly higher than 12.0%(18/150)in control groups.(2)History:compared with the control group(12.7 %,19/150;28.7%,43/150;11.3%,17/150;12.0%,18/150;17.3%,26/150),patients with pelvic adhesions present more incidence abortion(23.6%,87/369),uterine cavity operation(38.2%,141/369),ectopic pregnancy(20.9%,77/369),pelvic inflammatory disease(25.5%,94/369)and abdominopelvic surgery (31.4%,116/369).(3)Endoscopy exploration:the incidence of hydrosalpinx(24.7%,91/369),tube distorted(15.7%,58/369)and salpingostomy(72.9%,269/369)in adhesion group were higher than those in control group(2.0%,3/150;4.0%,6/150;12.0%,18/150),but relatively lower incidence of pelvic endometriosis lesions(5.7%,21/369)and mesosalpinx cysts(16.3%,60/369)than those in control group(16.0%,24/150;30.0%,45/150).The rate of proximal tubal recanalization(59.5%,91/153)in adhesion group was lower than 75.4%(52/69)in control group.However,the rate of distant tubal recanalization of 84.4%,(281/333)in adhesion group and;13/15 in control group didn't show statistical difference.(4)Prognosis:the rate of ectopic pregnancy of 9.7%(29/299)in adhesion group was significantly higher than 3.1%(4/128)in control group.Among cases with grade Ⅲ adhesion exhibited the highest rate of ectopic pregnancy(13.0%,7/54;OR =4.62,95% CI:1.29-16.50).(5)Multivariate analysis:it was found that more than two drug abortions(OR =3.29,95% CI:1.34-8.07),pelvic and (or)abdominal surgery history(OR =2.20,95% CI:1.35-3.57)and pelvic inflammatory disease history (OR =1.54,95% CI:1.21-1.97)were risk factors with pelvic adhesions.Conclusion More than or equal to two drug abortion history,pelvic inflammatory disease and pelvic and abdominal surgery damage were important factors for pelvic adhesions of infertility patients,which may decrease the possibility of proximal tubal recanalization and increase ectopic pregnancy risk.

Objective:
To examine the relationship between 7, 8-dihydrodio1-9.10-epoxide benzo[a] pyrene-DNA adducts (BPDE-DNA adducts) in the blood of pregnant women and gestational diabetes mellitus (GDM) and explore the environmental factors of the formation of GDM.
Methods:
Forty pregnant women who were diagnosed GDM (case group) and 40 pair-matched normal pregnantwomen who had no complications accordingto age, gravidity, parity and gestational weeks(normal control group) were enrolled in this study. Questionnaire survey was used to obtain personal information, and BPDE-DNA adducts was examined by high performance liquid chromatography. Logistic regression model was used to analyze the relationship between BPDE-DNA adductsand GDM.
Results:
The concentration of BPDE-DNA adducts in peripheral blood of case group [(6.1 ± 2.9) adducts/108nucleotides] was significantly higher than that of normal control group [(3.0 ± 1.7) adducts/108nucleotides] (

Objective :
To evaluate the prognostic value of a radiomics model based on the peritumoral region of gli- oma.
Methods :
138 patients with glioma were retrospectively analyzed ,medical imaging interaction toolkit ( MITK) software was used to obtain the magnetic resonance imaging (MRI) images of peritumoral area 5 mm,10 mm and 20 mm from the tumor edge and extract texture features.The texture features were screened the radiomics model was established and the radiomic score was calculated.A clinical prediction model and a combined predic- tion model along with Rad-score and clinical risk factors were established.The combined prediction model was dis- played as a nomogram,and the predictive performance of the model for survival in glioma patients was evaluated.
Results :
In the validation set,the C-index value of the radiomics model based on the peritumoral region 10 mm a- way from the tumor edge based on T2 weighted image (T2WI) images was 0. 663 (95% CI = 0. 72-0. 78) ,resul- ting in the best prediction performance.On the training set and validation set,the C-index of the nomogram was 0. 770 and 0. 730,respectively,indicating that the prediction performance of nomogram was better than those of the radiomics model and clinical prediction model.The model had the highest prediction effect on the 3-year survival rate of glioma patients (training set area under curve (AUC) = 0. 93,95% CI = 0. 83 - 0. 98 ; validation set AUC = 0. 88,95% CI = 0. 76 -0. 99) .The calibration curve showed that the joint prediction nomogram in both the training set and the validation set had good performance.
Conclusion
The combined prediction model based on the preoperative T2WI images in the peritumoral region 10 mm from the tumor edge and the clinicopathological risk factors can accurately predict the prognosis of glioma,providing the best effect of prediction on the 3-year survival rate of glioma.
