ABSTRACT

Objective:To study the risk factors of adverse pregnancy outcomes for induced abortion of cesarean scar pregnancy in midtrimester.Methods:A national multicenter retrospective study was conducted. A total of 154 singletons pregnant women with cesarean scar pregnancy during the second trimester induced abortion by various reasons in 12 tertiary A hospitals were selected, their pregnant outcomes were observed and the risk factors of serious adverse outcomes were analyzed with univariate and multivariate logstic regression; the role of ultrasound and MRI in predicting placenta accreta and severe adverse outcomes was evaluated, the effectiveness of uterine artery embolization (UAE) in preventing hemorrhage in pregnant women with and without placenta accreta was compared.Results:Among 154 subjects, the rate of placenta accreta was 42.2% (65/154), the rate of postpartum hemorrhage≥1 000 ml was 39.0% (60/154), the rate of hysterectomy was 14.9% (23/154), the rate of uterine rupture was 0.6% (1/154). The risk factor of postpartum hemorrhage≥1 000 ml and hysterectomy was placenta accreta ( P<0.01). For each increase in the number of parity, the risk of placenta accreta increased 2.385 times (95% CI: 1.046-5.439; P=0.039); and the risk of placenta accreta decreased with increasing ultrasound measurement of scar myometrium thickness ( OR=0.033, 95% CI: 0.001-0.762; P=0.033). The amount of postpartum hemorrhage and hysterectomy rate in the group with placenta accreta diagnosed by ultrasound combined with MRI were not significantly different from those in the group with placenta accreta diagnosed by ultrasound only or MRI only (all P>0.05). For pregnant women with placenta accreta, there were no significant difference in the amount of bleeding and hysterectomy rate between the UAE group [median: 1 300 ml; 34% (16/47)] and the non-embolization group (all P>0.05); in pregnant women without placenta accreta, the amount of bleeding in the UAE group was lower than that in the non-embolization group (median: 100 vs 600 ml; P<0.01), but there was no significant difference in hysterectomy rate [2% (1/56) vs 9% (3/33); P>0.05]. Conclusions:(1) Placenta accreta is the only risk factor of postpartum hemorrhage≥1 000 ml with hysterectomy for induced abortion of cesarean scar pregnancy in midtrimester; multi-parity and ultrasound measurement of scar myometrium thickness are risk factors for placenta accreta. (2) The technique of using ultrasound and MRI in predicting placenta accreta of cesarean scar pregnancy needs to be improved. (3) It is necessary to discuss of UAE in preventing postpartum hemorrhage for induced abortion of cesarean scar pregnancy in midtrimester.

ABSTRACT

Objective:To evaluate the clinical effectiveness of combining electrical stimulation with manual massage in treating women′s myofascial pelvic pain (MPPS).Methods:A total of 93 MPPS patients were recruited and randomly divided into an infrared irradiation group ( n=30), an electrical stimulation group ( n=31) and a combination group ( n=32). Those in the infrared group and the electrical stimulation group were given 30 minutes of infrared irradiation or electrical stimulation daily for 10 days, while the combined group was given a manual massage with electrical stimulation. The response to treatment was evaluated using a visual analogue scale (VAS) to rate discomfort, plus a physical examination, and surface electromyography results using Glazer′s protocol. The treatments′ efficacy and the recurrence of pain were evaluated 1 month after the treatment. Results:The average VAS ratings, resting potentials and their variability of the three groups all improved significantly after the treatment. The average VAS scores of the combined and electrical stimulation groups after the treatment were significantly lower than that of the infrared group. Moreover, the total effective rates of the combined group (96.87%) and the electrical stimulation group (80.65%) were significantly higher than that of the infrared group (56.67%), and the resting potential and variability of the former two groups were also significantly better. All of the above measurements among the combined group after the treatment were significantly better, on average, than in the electrical stimulation group. A month later the recurrence rate in the combined group (6.25%) was significantly lower than in the electrical stimulation group (25.81%) and the infrared group (56.67%).Conclusion:Electrical stimulation combined with manual massage is effective in relieving myofascial pelvic pain.

ABSTRACT

Reverse transcription-PCR and methylation-specific PCR (MSP) were used to determine the expression levels of Syk gene and the methylation status of its promoter in tissue samples from 60 patients with cervical cancer, 50 patients with cervical intraepithelial neoplasia (CIN), and 20 normal controls. We also analyzed the association of the methylation status and expression levels of Syk gene with linicopathological features of patients. The expression rates of Syk gene in 20 normal cervical tissue samples and 18 CIN Ⅰ samples were both 100% ; those of CIN Ⅱ- Ⅲ and cervical carcinoma were 56% (18/32)and 35% (21/60) respectively. Among cervical carcinoma patients, the expression of Syk mRNA was detected in one out of 13 cases with lymph node metastasis (1/13) and in 20 out of 47 cases with no lymph node metastasis (43%). The methylation of Syk gene in promoter region was detected in 34 out of 60 cases of cervical carcinoma (57%) ; while there was no methylation in CIN cases. In 13 cases with lymph node metastasis, 11 were found to have the methylation of Syk gene. The methylation rate of Syk promoter in cervical carcinoma was higher than that of CIN tissue( x~2 = 7. 13, P <0. 01 ). The methylation status of Syk gene was correlated with the lymph node metastasis ( P< 0. 05 ), but not with other clinicopathological parameters ( P > 0. 05). There was a significant correlation between methylation status and expression level of Syk gene ( P < 0. 05 ). The hypermethylation leads to silencing of the Syk gene in human cervicalcarcinoma. Syk hypermethylation may be associated with oncngenesis, metastasis of cervical carcinoma.

ABSTRACT

Background and Purpose:Cervical cancer is one of the most common malignant neoplasms among women.The 5-year survival for patients with early stage disease is over 70%.While it is generally accepted that either radical surgery or radiotherapy can achieve cure for the majority of patients with early-stage cervical cancer,there is no standard approach to the patients with bulky disease,whose prognosis remains very poor in spite of the therapeutic advances achieved in recent years.Neoadjuvant chemotherapy has been used as part of the multidisciplinary treatment before either operation or radiation therapy.Although the approach still had many controversies,numerous studies have supported its effectiveness in bulky cervical cancer.The present study was conducted to explore whether neoadjuvant chemotherapy with the combination of vincristine,bleomycin and cisplatin could improve the operability and pathological response rate in Ⅰb_(2)~Ⅱb bulky cervical cancer patients.Methods:A total of fifty-six patients with bulky cervical cancer were histologically diagnosed and staged into Ⅰb_(2)~Ⅱb according to the standards of International Federation of Gynecology and Obstetrics(FIGO) and randomly selected,including 15 cases with Ⅰb_(2),15 with Ⅱa,26 with Ⅱb.They were treated by a regimen of PVB chemotherapy for 2 cycles and followed by operation.The immediate response and adverse effects were analyzed.Results:The overall response rate was 78.6%.The resectability rate for surgery after chemotherapy was 100%.No intolerable toxic and adverse effects were recorded during neoadjuvant chemotherapy.Preoperative neoadjuvant chemotherapy can apparently increase the possibility of resection by operation and enhance the remission rate.The primary tumor sizes were significantly decreased after chemotherapy before surgery(P

ABSTRACT

Background and purpose:Vascular endothelial growth factor-C(VEGF-C) is ranked first as a lymphoangiogenic factor, which induces lymphatic proliferation and spread of solid tumors. Lymph node status remains the strongest prognostic factor in a variety of human malignant tumors including uterine cervical carcinomas and lymphnode metastasis is stimulated by tumor cell aggressiveness, such as abilities of growth and metastases.We examined the correlation between VEGF-C expression and tumor aggressiveness in cervical carcinomas with respect to clinicopathologic features and patient outcome and to see whether the expression of VEGF-C and its receptor in cervical carcinoma tissue and their paratumour tissue had a role in tumor metastasis and other clinical significance. Methods:48 fresh cervical cancer tissues and their paratumour tissue were examined by RT-PCR to detect the VEGF-C/KDR/Flt-4mRNA expression.Results:There was a significant difference of VEGF-C/KDR/Flt-4mRNA expression between the tumor , paratumour tissue and the normal controls. And there was no significant relationship between VEGF-C mRNA, KDR mRNA or flt-4mRNA expression with the pathological types and clinical stage of invasive carcinoma of cervix. However,expression was significantly associated with the grade of tumor pathology, lymph node metastasis, tumor size and the invasion of deep muscular layer(P
