ABSTRACT
Objective: To investigate the effects of traditional Chinese medicine, Danzhi decoction, on the expression angiogenesis factors in human endometrial cells during the sequelae of pelvic inflammatory disease (SPID) and explore the role of Danzhi decction in improving the blood stasis microenvironment of SPID. Methods: A three-dimensional (3D) co-culture system including human vascular endothelial cells (VECs), endometrial stromal cells and glandular epithelial cells was established in vitro and treated with Danzhi decoction, sterilized water and aspirin respectively. A Milliplex multifunctional liquid chip technique was used to measure the expression levels of vascular endothelial growth factor (VEGF)-A/C/D, fibroblast growth factor -1/2, angiopoietin-2, epidermal growth factor (EGF), HB-EGF, bone morphogenetic protein-9, endoglin, endothelin-1, granulocyte colony stimulating factor, hepatocyte growth factor, interleukin-8, follistatin, placenta growth factor and leptin. The location of angiogenesis factors was monitored by immunofluorescence labeling and confocal laser scanning microscope 3D reconstruction. Results: Endometrial stromal cells and glandular epithelial cells were isolated and primary cultured for establishing a 3D co-culture system. The levels of VEGF-A/C/D in Danzhi decoction group and aspirin group were significantly lower than those in mock group (. P0.05). Furthermore, the alterative location of VEGF-A/C/D was observed in the cytoplasm of endometrial glandular epithelial cells. Conclusions: Danzhi decoction may inhibit the expression of VEGF in the blood stasis microenvironment of SPID by targeting the cytoplasm of endometrial glandular epithelial cell.

ABSTRACT
Objective To learn the influence of density of LPS and LPS + PDTC on the concentration of IL -1? of endometrial cells. Method We used LPS and LPS + PDTC to intervene normal and endometriosis patients, and obtain cultivate supernatant,then detected the concentration density of IL - 1?with ELISA. Result The of IL - 1? had no statistical signifiance in normal endometrial cells, but there was notable change in eutopic and ectopic endometrial cells. Conclusion Activating and refrainning NF -?B through LPS and PDTC, then decteting the change of the ancentration of IL - 1?, understanding the relation between NF -?B and endometriosis are all important in pathogenesis.
ABSTRACT
The significance of endometrial cells on cervicovaginal smears is underestimated. The aim of this study is to evaluate the detection rate of endometrial cells on cervicovaginal smears. The materials consisted of two groups. Group I was 701 cervicovaginal smears from patients with no gynecological problems. Group II was 208 cervicovaginal smears from patients with abnormal uterine bleeding followed by endometrial curettage; 31 cases of endometrial adenocarcinoma(CA), 19 cases of endometrial hyperplasia(HP), 83 cases of dysfunctional uterine bleeding(DUB), and 75 cases of normal endometrium. Cervicovaginal smears were reviewed according to the criteria of The Bethesda System. Endometrial cells were identified in 15 of 701 cases(2.1%) in group I and 64 of 208 cases(30.8%) in group II. Among group II, detection rate of endometrial cells was the highest in CA (51.6%) compared to HP(26.3%), DUB(41.0%), and normal endometrium(12.0%) ( p<0.05). Cytologic atypia of endometrial cells was not found in group I, but was more frequently identified in CA(87.5%) than in HP(10.5%) or DUB(14.7%) ( p<0.05). Exfoliation of endometrial cells might be related to abnormal endometrial lesion, and reporting of endometrial cells in the cervicovaginal smear may increase a chance to detect endometrial lesions especially in patients with abnormal uterine bleeding.

OBJECTIVE: The purpose of this study is to evaluate the histologic correlations and the clinical significance among patients with atypical squamous cells of undetermined significance (ASCUS), atypical glandular cells of undetermined significance(AGUS) and benign endometrial cells identified on cervical Pap smear screening. MATERIALS & METHODS: The computerized files of the Department of Pathology at Samsung Cheil Hospital were searched from 1991 to 1997 to evaluate the annual statistics of cytologic diagnoses including normal/benign, ASCUS, AGUS, low-grade squamous intraepithelial lesion (LSIL), high-grade squamous intraepithelial lesion(HSIL) and cancer classified by the Bethesda System(TBS). Cytohistologic correlations on follow-up were separately analysed in ASCUS(190 cases), AGUS(268 cases) and benign endometrial cells(169 cases), respectively. Additionally, post-menopausal squamous atypia(83 cases) were also included in this study. TBS terminology was used in both cytologic and histologic diagnoses. RESULTS: During 7-year period (1991-1997), 447,049 cervicovaginal smears were evaluated. The median rate of abnormal cytology was 4.4%, with 2.1% of ASCUS, 2.06% of squamous intraepithelial lesion(SIL), and 0.08% of AGUS. The median ratio of ASCUS versus SIL was 1.24. Specimen adequacy was evaluated on 47,525 cases, of which categories of "satisfactory for evaluation but limited by" and "unsatisfactory for evaluation" were 28.3% and 0.03%, res-pectively. Follow-up of 190 patients with ASCUS cytology showed 30%(57 cases) with SIL on biopsy; 18%(35cases) with LSIL, 11%(21cases) with HSIL, and 1%(1case) with microinvasive squamous cell carcinoma. On histologic examination, 77%(37/48cases) with ASCUS favoring SIL revealed SIL in contrast to 14%(20/142cases) with ASCUS favoring reactive change, which is statistically significant.(Chi-Square test, P<0.0001). Of 83 cases of post-menopausal squamous atypia(PSA), smears with LSIL showed 34.9%(15/43cases) with LSIL on biopsy. 268 patients with AGUS smears had 25%(67cases) with clinically significant cervical or endometrial lesions on histologic examinations. Among 17.9%(48cases) with cervical lesions, squamous abnormalities were 10.5%(28cases); including 1.5%(4cases) with LSIL and 9.0%(24cases) with HSIL. Glandular lesions in cervix were 7.5%(20cases); 3.0%(8cases) of glandular atypia or dysplasia, 1.9%(5cases of adenocarcinoma in situ, 1.1%(3cases) of microinvasive adenocarcinoma and 1.5%(4cases) of adenocarcinoma. Of 7.1%(19cases) of endometrial lesions, 2.2%(6cases) was endometrial hy-perplasia, 4.1%(11cases) endometrial carcinoma, 0.4%(1case) MMMT and 0.4%(1case) metastatic adenocarcinoma from stomach were verified. The pathologies of 169 cases with benign endometrial cells shed in cervicovaginal smears were confirmed to be endometrial polyp(8.3%), endometrial hyperplasia(4.1%) and endometrial carcinoma(5.9%). CONCLUSION: The results of this study indicates that clinicians should communicate with pathologists for proper management of abnormal cytology. Further evaluation and decision of management should be made based on input from pathologists as well as on clinical setting and professional guidelines.
