ObjectiveTo systematically review the value of human epididymis protein 4 (HE4) in early diagnosis of endometrial cancer. MethodsDatabases including The Cochrane Library (Issue 1, 2013), PubMed, MEDLINE (Ovid), CNKI, CBM and WanFang Data were electronically searched for relevant studies on HE4 versus the golden standard (pathological examination) in the diagnosis of endometrial cancer from inception to April 2013. Meanwhile, relevant journals were also manually searched. Two reviewers independently screened literature according to the inclusion and exclusion criteria, and evaluated the included studies using the QUADAS items. Then, meta-analysis was performed using RevMan 5.1 and Meta-DiSc 1.0. ResultsFinally, a total of 16 studies involving 2 299 women (1 088 endometrial cancer patients diagnosed according to the golden standard, of which, 504 with benign uterine disease and 707 with normal cervical) were included. The results of meta-analysis showed that, as for HE4 in early diagnosis of endometrial cancer (SEN=57%, 95%CI 0.54 to 0.60; SPE=92%, 95%CI 0.91 to 0.94; +LR=6.92, 95%CI 5.00 to 9.58;-LR=0.46, 95%CI 0.39 to 0.55; DOR=18.38, 95%CI 12.21 to 27.69; AUC=0.881 7). ConclusionThe current study indicates that serum HE4 is more sensitive and low specific when applied in patients with endometrial cancer, which is worth of being used in clinic. Due to the limitation of low quality of the included studies, more high quality trials are required to verify the above conclusion.
Objective To explore the application value of self-made visual teaching aids in gynecological and obstetrical nursing education. Methods A total of 240 nursing students in grade 2009 from Fujian Medical University and Fujian Health College were selected by cluster sampling and divided by simple randomization into 2 groups (the trial group and the control group). Besides the multimedia combined with traditional teaching adopted in both groups, the visual teaching aids for fetal intrauterine condition was also adopted in the trial group rather than the control group. Questionnaire survey and focus group interview were adopted to appraise the satisfactory degree of all nursing students and the teaching effects evaluation of students in the trial group. Results There were no significant differences between the two groups in education background, and intelligibility evaluation of theoretical study on both the fetal intrauterine condition and the complications in pregnancy and delivery periods (Pgt;0.05), while the difference was statistically significant in the satisfactory degree between different teaching methods (Plt;0.05). 85.0% of nursing students in the trial group thought that visual model could help them to better understand the complications in pregnancy and delivery periods, and the intrauterine condition, 99.17% of students thought that the teaching effect of visual model was better than traditional teaching, and 95.83% of students considered that visual model was favorable for course study. Conclusion The application of self-made visual teaching aids for fetal intrauterine condition makes gynecological and obstetrical nursing education more visual, facilitates students to better understand fetal intrauterine situation and part of the mechanism of pregnancy complications, arouses students’ learning interests, and lays a theory and practice foundation for follow-up internship, so as to enhance the quality of nursing teaching.

Methods Thirty-eight patients with endometrial carcinoma confirmed by surgicopathology undergone dynamic-enhanced MRI scans were analyzed retrospectively. The invasion in myometrium and uterine cervix were analyzed. The tumor and myometrium contrast-to-noise ratios during different phases of dynamic imaging were calculated. MR imaging findings were compared with pathologic findings. Sensitivity, specificity, diagnostic accuracy, positive and negative predictive values of MR imaging in depicting myometrial and cervical infiltration were calculated. Results Respective sensitivity, specificity, and positive and negative predictive values in assessing myometrial infiltration were 968%,85.7%,96.8%,85.7%;those for cervical infiltration were 85.7%,91.7%,85.7%,91.7%,respectively. The diagnostic accuracy (94.7%) of dynamic imaging in depicting deep myometrial infiltration were significantly higher than that of T2WI (78.9%) (Plt;0.05).There was a significant improvement in tumor and myometrium contrast-to-noise ratios during the equilibrium phase compared with the arterial and venous phases (Plt;0.01). Conclusion Dynamic-enhanced MRI is highly accurate in preoperative diagnosis of endometrial carcinoma, which will benefit for the treat of endometrial carcinoma.
ObjectiveTo investigate the effect of laparoscopic surgery combined with the following treatment of gonadotropin-releasing hormone agonist (GnRH-a) on the patients with endometriotic infertility and the value of endometriosis fertility index (EFI) system on forecasting the pregnancy outcome. MethodsFrom January 2005 to July 2011, the clinical data of 15 patients with endometriotic infertility patients were analyzed retrospectively. All the patients underwent laparoscopic surgery, and the effect was evaluated according to the endometriosis fertility index (EFI). Then all the patients were divided randomly into two groups on the basis of the different assisted treatment after the laparoscopic surgery:the control group (without any other therapy) and the GnRh-a group (combined with GnRH-a). Eventually, the pregnant rates were calculated respectively in the different groups or according to the different EFI. ResultsAt last, 103 cases finished the follow-up. The pregnancy rate in the control group after 6 months, 1 year and 3 years therapy were 12.5%, 31.2%, and 41.7%, respectively; while in the GnRh-a group were 0%, 16.3%, and 40.0%, respectively. There were no difference between the two groups after the 1 year and 3 years therapy (P>0.05). Besides, all of the 55 cases in the GnRh-a group had side-effects, but no severe adverse effect was encountered. All the side-effects were disappeared after stopping the treatment. The pregnancy rate of the patients with the EFI score of 8-10 was respectively 31.3% 1 year and 62.5% 3 years after the treatment. However, the pregnancy rate of the patients with the EFI score of 5-7 was respectively 15.2% 1 year and 26.0% 3 years after the treatment. There were only 9 patients with the EFI score of 0-4, and all of them were not pregnant. The EFI score had positive correlation with the pregnancy rate 1 year and 3 years after the treatment (rs=0.204, P=0.039; rs=0.437, P<0.001). ConclusionThe treatment of GnRh-a after the laparoscopic surgery can not only increase the rate of the pregnancy, but also delay the pregnancy occasion and increase the occurrence of the side-effects. The EFI may be valuable for forecasting the rate of pregnancy in patients with endometriotic infertility. The patients with EFI score higher than 8 may expect the pregnancy, while the ones with below 7 probably have much lower rate of natural pregnancy rate.
ObjectiveTo systematically review the effectiveness and safety of laparoscopy with postoperative gonadotropin releasing hormone agonist (GnRH-a) versus laparoscopy alone for endometriosis. MethodsRandomized controlled trials (RCTs) on laparoscopy with postopertative GnRH-a versus laparoscopy alone in treatment of endometriosis were retrieved in the following databases:the Cochrane Library (Issue 3, 2013), PubMed, EMbase, WanFang Data, CNKI, and CBM from inception to February, 2013. According to the inclusion and exclusion criteria, the literature were screened, the data was extracted and the methodological quality of the included studies was also assessed by two reviewers independently. Then, meta-analysis was performed using RevMan 5.1.7 software. ResultsA total of 15 RCTs involving 1 761 patients were included. There were statistically significant differences between the laparoscopy with postoperative GnRH-a group and the laparoscopy alone group in the following 4 aspects:the symptom relief rate (RR=1.24, 95%CI 1.16 to 1.33, P < 0.000 01), the recurrence of lesion (RR=0.35, 95%CI 0.24 to 0.51, P < 0.000 01), the recurrence of pain (RR=0.70, 95%CI 0.53 to 0.92, P=0.01), and the pregnancy rate (RR=1.43, 95%CI 1.25 to 1.65, P < 0.000 01). ConclusionLaparoscopy postoperative GnRH-a for endometriosis can enhance the symptom relief rate, reduce the recurrence of lesion and the recurrence of pain, and increase the pregnancy rate. But because of the limitation of the quality of the included studies and publication bias, the above conclusion should be verified by conducting more high quality RCTs.
Pulmonary endometriosis (PEM) is a rare disease with diverse clinical manifestations, most commonly presenting as hemoptysis, while patients presenting solely with pulmonary nodules are less common. Here, we report three female patients (aged 32, 19, and 46 years, respectively). One patient sought medical attention due to hemoptysis during menstruation, while the other two had no obvious symptoms and were found to have pulmonary nodules during routine physical examinations. Two patients had a history of cesarean section, and one had a history of miscarriage. Pathologically, one patient of PEM showed extensive hemorrhage in the alveolar spaces, with fragmented endometrial glandular epithelium observed within the hemorrhagic foci. The other two patients exhibited proliferative endometrial glands and stroma, surrounded by old hemorrhage. Immunohistochemistry revealed that the endometrial glands and stroma in all three patients were positive for estrogen receptor, progesterone receptor, and vimentin, with CD10 positivity in the endometrial stroma. All three patients were definitively diagnosed as PEM by pathology and underwent thoracoscopic pulmonary wedge resection. Follow-up periods were 18, 31, and 49 months, respectively, with no recurrence observed in any of the patients.
Objective To investigate the endometrial thickness and echo patterns of healthy women, so as to provide a basis for the formulation of a standard to define normal endometrium in Chinese women. Method A total of 1872 married healthy women in Yongchuan District received transvaginal ultrasound examination. The endometrial sonograph was observed and endometrial thickness was measured for statistical analyses. Results In pre-menopausal women of different age groups, the endometrial thickness was increased and the endometrial echo was enhanced from the proliferative phase, ovulatory phase and secretory phase. The endometrial thickness varied significantly among different menstrual cycles, while no significant difference was observed in the endometrial thickness of a same menstrual cycle among women of different age groups. Pre-menopausal women had significantly different endometrial thickness when compared with post-menopausal women. Conclusion Through a general survey of women by transvaginal ultrasound, a large sample database can be established, which may contribute to the formulation of a standard to define normal endometrium in Chinese women and to help identify abnormal endometrium.
