Objective To explore the efficacy and safety of methotrexate combined with hysteroscopic in treatment of cervical pregnan-cy. Methods The data of 14 patients with cervical pregnancy were analyzed retrospectively. Results All patients were given combination therapy of mifepristone and methotrexate firstly,and they were discharged after bloodβ-HCG logarithmically decreased for further observation. Hysteroscopic surgery were applied whenβ-HCG level decreased to 100 mIU/mL. Conservative treatment received success in all 14 cases. It required 14~35 days,averagely (26. 5 ± 2. 7) days, methotrexate dosage of 50~150 mg,averagely (75. 5 ± 15. 0) mg, and mifepristone of volume 150~450 mg,averagely (275. 0 ± 54. 5) mg to make the bloodβ-HCG level decreased to 100 mIU/mL. The bleeding volume during hysteroscopy surgery was 5~50 mL,an average of (35. 6 ± 5. 2)mL. Conclusion Methotrexate combined with hysteroscopy is safe and fea-sible for treatment of cervical pregnancy.

Objective To examine the frequency of coexisting endometrial carcinoma with preoperative diagnosis of endometrial atypical hyperplasia (EAH).Methods From Apr 2002 to Apr 2007,61 consecutive patients diagnosed as EAH who underwent total hysterectomy in our department were retrospectively analyzed.Patients were stratified as 44 premenopausal cases and 17 menopausal cases.The patients were divided into 2 groups depending on whether or not cancer cells were found by histology in removed uterus (cancer group vs EAH group) to explore valuable predictive risk factors for concomitant endometrial carcinoma through reviewing the clinical data.Logistic regression analysis and logistic regression equation are used to evaluate the risk of coexisting endometrial carcinoma with preoperative diagnosis of endometrial atypical hyperplasia.Results Endometrial thickness and the type of EAH were selected into the equation in premenopausal cases,showing statistically significant differences(P ＜ 0.001) and the overall accuracy was 86.4％.Menopausal years and the type of EAH were selected into the equation in menopausal women,also showing statistically significant differences (P ＜ 0.04)and the overall accuracy was 82.4％.Conclusions Endometrial thickness and the type of EAH are valuable in predicting the risk of endometrial carcinoma in premenopausal women.Menopausal years and the type of EIN are valuable in prediciting the risk of coexistance with endometrial carcinoma in menopausal women.

Objective:To analyze the effect of Doula delivery combined with labor analgesia on the delivery process and delivery outcomes of primiparas.Methods:Retrospectively selected 200 primiparas treated in Beijing Friendship Hospital, Capital Medical University from January 1, 2019 to September 30, 2019 as the research objects.All patients underwent labor analgesia, and were divided into 100 cases in the Doula group and 100 cases in the control group (without Doula delivery) according to whether or not Doula delivery was performed.T test of two independent samples and chi square test were used to compare the labor process and delivery outcome of the two groups.Results:The natural delivery rate in the Doula group was 76%(76/100), which was significantly higher than the control group (61%(61/100)), and the difference was statistically significant (χ 2=5.214, P=0.022). The time of the first, second and third stage of labor in Doula group was (8.35±3.59), (1.07±0.26), (0.54±0.19) h, and that in the control group was (10.94±4.76), (1.86±0.63), (0.78±0.21) h, respectively.There were significant differences between the two groups (t value were 10.354, 5.312 and 8.169, respectively; P value were 0.016, 0.042 and 0.039, respectively). The neonatal asphyxia rates of Doula group and control group were 1% (1/100) and 3% (3/100) respectively, and there was no significant difference between the two groups ( P=0.621). The incidence of postpartum hemorrhage in the Doula group and the control group was 3% (3/100) and 10% (10/100) respectively, and the incidence of postpartum urinary retention was 0 (0/100) and 6% (6/100), respectively.The success rate of early sucking was 98% (98/100) and 90% (90/100) respectively, and the difference between the two groups was statistically significant (P value were 0.045, 0.029 and 0.017, respectively). The hospitalization time of Doula group was (3.17±0.85) d, which was significantly shorter than that of the control group (5.64±1.29) d)( t=6.359, P=0.031). The visual analogue pain score of 2 h postpartum in Doula group was 3.49±0.98, which was significantly lower than the control group (5.82±1.06)( t=9.327, P<0.001). Conclusion:Doula delivery combined with labor analgesia can effectively reduce the pain of uterine contraction, promote natural delivery, reduce the rate of cesarean section, help to improve the quality of obstetric medical service, improve patient satisfaction, it is worth promoting in the condition of the hospital.

Objective To study the effect of thrombin on proliferation and invasion of esophageal cancer cell line Eca109, and to explore its possible mechanism. Methods The proliferation and invasion of Eca 109 cells treated with thrombin were detected by MTT and Transwell assay, respectively. The activity of matrix metalloproteinase 2 (MMP-2) and MMP-9 in the supernatant of Eca109 cells was detected by gelatin zymography. Reverse transcription polymerase chain reaction (PCR) and immunocytochemistry were used to study the mRNA expression of protease-activated receptor 1 (PAR-1), the important receptor of thrombin, and subcellular localization of PAR-1 protein in Eca109 cells, respectively. Results Thrombin could promote Eca109 cells proliferation in a dose-dependent manner. Cell proliferative rates of 0.5 U/ml and 1.0 U/ml thrombin were 34.38 % and 57.19 %, respectively (P< 0.05). Compared to that of control group, the number of Eca109 cells incubated with 1.0 U/ml thrombin invading through the basement membrane of Transwell was increased (303.33 ±6.66 vs. 116.33 ±11.51, P< 0.05). When treated with various concentrations of thrombin for 24 h, the activities of MMP-2 and MMP-9, especially MMP-9, in the supernatant of Eca109 cells were increased in a dose-dependent manner. Eca109 cells expressed PAR-1 mRNA, and PAR-1 protein was mainly located on the cellular membrane. Conclusion Thrombin increases proliferation and invasion of esophageal cancer Eca109 cells and enhances the activities of MMP-2 and MMP-9 in cells supernatant, which might be induced by activation of PAR-1 located on cellular membrane.

Cinobufacini is an aqueous extract of Bufo bufo gargarizans Cantor dried skin, which has been widely used for cancer therapy in China. So far, its active components are still not very clear. In previous reports, bufadienolides with low-concentration were usually studied because of their anticancer effects. However, the high polarity constituents in cinobufacini are less investigated. The present study found that more than 50% contents of cinobufacini were water-soluble peptides. Then, in vitro anticancer experiments were carried out, including human stomach cancer cell lines BGC823 and MCG803, human colon cancer cell lines DLD-1 and HT-29, and human pancreatic cancer cell line MIAPACA-2. The IC50 for these cell lines model were ranged from 25-123 microgmL(-1). The results indicated that these peptides showed similar activity with cinobufacini injection. As a conclusion, this study provides a new and further understanding of anticancer components in cinobufacini injection.
