Objective: To perform intrauterine adhesion modeling, and to investigate the repair effect of hypoxic treated bone marrow mesenchymal stem cells (BMSC) and their derived exosomes (BMSC-exo) on endometrial injury. Methods: BMSC and their exosomes BMSC-exo extracted from rats' femur were cultured under conventional oxygen condition (21%O2) or hypoxia condition (1%O2). Intrauterine adhesion modeling was performed on 40 healthy female SD rats by intrauterine injection of bacterial lipopolysaccharide after curettage. On the 28th day of modeling, 40 rat models were randomly divided into five groups, and interventions were performed: (1) NC group: 0.2 ml phosphate buffered solution was injected into each uterine cavity; (2) BMSC group: 0.2 ml BMSC (1×106/ml) with conventional oxygen culture was injected intrauterine; (3) L-BMSC group: 0.2 ml of hypoxic cultured BMSC (1×106/ml) was injected intrauterine; (4) BMSC-exo group: 0.2 ml of BMSC-exo cultured with conventional oxygen at a concentration of 500 μg/ml was injected into the uterine cavity; (5) L-BMSC-exo group: 0.2 ml hypoxic cultured BMSC-exo (500 μg/ml) was injected intrauterine. On the 14th and 28th day of treatment, four rats in each group were sacrificed by cervical dislocation after anesthesia, and endometrial tissues were collected. Then HE and Masson staining were used to observe and calculate the number of glands and fibrosis area in the endometrium. The expressions of angiogenesis related cytokines [vascular endothelial growth factor A (VEGFA) and CD31], and fibrosis-related proteins [collagen-Ⅰ, collagen-Ⅲ, smooth muscle actin α (α-SMA), and transforming growth factor β1 (TGF-β1)] in endometrial tissues were detected by western blot. Results: (1) HE and Masson staining showed that the number of endometrial glands in L-BMSC group, BMSC-exo group and L-BMSC-exo group increased and the fibrosis area decreased compared with NC group on the 14th and 28th day of treatment (all P<0.05). Noteworthily, the changes of L-BMSC-exo group were more significant than those of BMSC-exo group (all P<0.05), and the changes of BMSC-exo group were greater than those of BMSC group (all P<0.05). (2) Western blot analysis showed that, compared with NC group, the expressions of collagen-Ⅲ and TGF-β1 in BMSC group, L-BMSC group, BMSC-exo group and L-BMSC-exo group decreased on the 14th and 28th day of treatment (all P<0.05). As the treatment time went on, the expressions of fibrosis-related proteins were different. Compared with BMSC group, the expressions of collagen-Ⅲ, α-SMA and TGF-β1 in the BMSC-exo group and L-BMSC group decreased on the 28th day (all P<0.05). Moreover, the expressions of collagen-Ⅲ and TGF-β1 in L-BMSC-exo group were lower than those in BMSC-exo group on the 28th day (all P<0.05). And the expressions of collagen-Ⅰ, α-SMA and TGF-β1 in L-BMSC-exo group were lower than those in L-BMSC group on the 28th day (all P<0.05). (3) The results of western blot analysis of VEGFA and CD31 showed that, the expressions of VEGFA and CD31 in BMSC group, L-BMSC group, BMSC-exo group and L-BMSC-exo group increased on the 14th and 28th day of treatment compared with NC group (all P<0.05). Treatment for 28 days, the expressions of VEGFA and CD31 in BMSC-exo group and CD31 in L-BMSC group were higher than those in BMSC group (all P<0.05). Moreover, the expressions of VEGFA and CD31 in L-BMSC-exo group were higher than those in BMSC-exo group and L-BMSC group on the 28th day (all P<0.05). Conclusions: Treatment of BMSC and their exosomes BMSC-exo with hypoxia could promote endometrial gland hyperplasia, inhibit tissue fibrosis, and further repair the damaged endometrium in rats with intrauterine adhesion. Importantly, hypoxic treatment of BMSC-exo is the most effective in intrauterine adhesion rats.

OBJECTIVES: To perform a systematic review and meta-analysis of the prognostic value of post-treatment 18F-fluorodeoxyglucose positron emission tomography (¹⁸F-FDG PET) in uterine cervical cancer patients treated with radiotherapy (RT) with or without chemotherapy. METHODS: PubMed and Embase databases were searched up to July 22, 2018, for studies which evaluated the response outcomes of ¹⁸F-FDG PET following RT, and their prognostic significance in uterine cervical cancer was assessed with overall survival (OS) or progression-free survival (PFS) as endpoints. Hazard ratios (HRs) were meta-analytically pooled using the random-effects model. RESULTS: Eleven studies with 12 patient cohorts including 1,104 patients were included. For a quantitative synthesis of OS, 7 cohorts were included. Two cohorts which reported disease-specific survival instead of OS were also included with flexibility. Pooled HR of complete metabolic response (CMR) compared to partial metabolic response (PMR) was 0.19 (95% confidence interval [CI]=0.11–0.31). Pooled HR of CMR compared to progressive metabolic disease (PMD) was more evident at 0.07 (95% CI=0.04–0.12), and that of CMR compared to both PMR and PMD was 0.20 (95% CI=0.12–0.34). Quantitative synthesis for PFS was performed with a total of 8 cohorts. Pooled HR of CMR was 0.17 (95% CI=0.10–0.29) compared to PMR, 0.02 (95% CI=0.01–0.06) compared to PMD and 0.12 (95% CI=0.07–0.19) compared to both PMR and PMD. CONCLUSION: Response results of post-RT ¹⁸F-FDG PET were significant prognostic factors in patients with uterine cervical cancer, and ¹⁸F-FDG PET could be a reasonable follow-up imaging modality.

The pathogenesis and therapeutic treatment of intrauterine adhesions (IUAs) remain unsolved, highlighting the need for stable and effective experimental animal models. In this study, uterine electrocoagulation of twenty-one female New Zealand White rabbits was carried out to establish an IUA model. As rabbits have two completely separate uterine horns, each rabbit had its own internal control: one uterine horn was given an electrothermal injury (Group A, n=21), and the contralateral uterine horn received no treatment and served as the control (Group B, n=21). The endometrial morphology, number of endometrial glands, area of endometrial fibrosis, and number of implanted fetuses were compared between the two groups. In Group A, the numbers of endometrial glands on Days 7 and 14 and the number of implanted fetuses were significantly lower than those in Group B (P<0.05, P<0.05, and P<0.01, respectively), while the ratio of the area with endometrial stromal fibrosis to the total endometrial area was significantly increased (P<0.01). These results suggest that this method of electrothermal injury is effective for the establishment of a rabbit IUA model between 7 and 14 d after surgery.

INTRODUCTIONWe aimed to evaluate the local incidences of hydronephrosis and renal impairment in the presence of severe uterovaginal or vault prolapse, and determine whether treatment by surgery or ring pessary resulted in the resolution of hydronephrosis in these patients.
METHODSThis was a retrospective case study of 121 patients who presented with severe uterovaginal or vault prolapse. All patients who had fourth degree uterovaginal or vault prolapse, and underwent renal ultrasonography and renal function blood tests were included in the study. Follow-up imaging for hydronephrosis was performed to determine the outcome after patients received treatment.
RESULTSThe mean age of the study population was 66.1 years. The overall incidence of hydronephrosis was 20.6%. The incidence of hydronephrosis in patients with severe vault prolapse was 7.1%, while that in patients with severe uterovaginal prolapse was 22.4%. Of the 25 patients with hydronephrosis, 16 (64.0%) had complete resolution of hydronephrosis after treatment, 5 (20.0%) had residual but smaller degrees of hydronephrosis, and 4 (16.0%) were lost to follow-up. The incidence of renal impairment was 3.3%.
CONCLUSIONThe local incidence of hydronephrosis in patients with severe uterovaginal or vault prolapse was 20.6% in our study. We established that 3.3% of women with severe uterovaginal or vault prolapse had mild renal impairment. Treatment by vaginal surgery for severe uterovaginal or vault prolapse appears to result in either complete resolution or improvement of hydronephrosis in the majority of patients.

OBJECTIVETo compare the efficacy, side effects and influence of two chemotherapy regimens, paclitaxel liposome combined with platinum and paclitaxel combined with platinum, on the survival rate in patients with cervical carcinoma receiving concurrent chemoradiotherapy.
METHODSOne hundred and sixty two cases with primary cervical carcinoma diagnosed and treated in the Jiangxi Maternal and Children Hospital between January 2008 and November 2009 were enrolled in this randomized controlled trial. Seventy one cases were included in the paclitaxel group and 91 in the paclitaxel liposome group. The chemotherapy doses were as followings: paclitaxel liposome and paclitaxel 135 mg/m(2); cisplatin 80 mg/m(2) or carboplatin AUC 4 - 6, repeated every 21 days for two or three times. Radical radiotherapy was given to both groups at the same time. The efficacy was evaluated by the tumor regression and the patients were followed-up for six months.
RESULTSThe overall response rates of paclitaxel group and paclitaxel liposome group were 90.1% and 89.0%, respectively (P > 0.05). The 1-year cumulative survival rate was 91.4% for the paclitaxel group and 89.2% for the paclitaxel liposom group (P > 0.05). The incidence rate of adverse effects such as rash, gastrointestinal toxicity, bone marrow suppression and muscle/joint pain in the paclitaxel liposome group was significantly lower than that in the paclitaxel group (P < 0.05), while there was no significant difference regarding the hair loss, liver damage, and peripheral neuritis (P > 0.05).
CONCLUSIONSPaclitaxel liposome plus platinum is a safe and effective therapeutic regimen for stage IIa-IV cervical carcinoma. However, the long-term efficacy of this regimen should be further observed.

OBJECTIVETo evaluate the effects of levonorgestrel-releasing intrauterine system (LNG-IUS) combined with GnRH analogue (GnRH-a) in the treatment of adenomyosis with uterine body enlargement.
METHODSTwelve women (mane age 40.3 years) with adenomyosis and uterine cavity depth over 11 cm received injections of GnRH-a every 4 weeks, and after the uterine cavity depth was reduced to below 10 cm, LNG-IUS was deployed. VAS pain score, PBAC bleeding score, uterine volume, and hemoglobin levels of the women were measured before the treatment and at 6 and 12 months after LNG-IUS placement.
RESULTSThe VAS pain score was significantly lowered at 6 and 12 month after LNG-IUS placement (P<0.05), and the PBAC bleeding score also showed significant reductions (P<0.05). The uterine volume decreased significantly at 6 and 12 months after LNG-IUS placement as compared with that before the treatment, but was significantly greater at 6 month in comparison with that at the time of LNG-IUS placement (P<0.05). Serum hemoglobin levels underwent significant increments after LNG-IUS placement (P<0.05).
CONCLUSIONLNG-IUS combined with GnRH analogue injection can be effective in the treatment of adenomyosis with dysmenorrhea and hypermenorrhea.

Pulmonary toxicity is one of the most serious adverse effects associated with a quick course of vincristine, bleomycin, and cisplatin neoadjuvant chemotherapy (NAC-VBP). The aim of this study was to evaluate pulmonary toxicity related to a quick course NAC-VBP. A total of consecutive 61 patients, who underwent at most 3 cycles of NAC-VBP every 10 days in the International Federation of Gynecology and Obstetrics (FIGO) stage IB-IIB cervical cancer from 1995 to 2007, were retrospectively analyzed. Of the 61 study subjects, 7 (11.5%) were identified to have pulmonary toxicity and 2 (3.3%) died of pulmonary fibrosis progression despite aggressive treatment and the use of a multidisciplinary approach. No factor predisposing pulmonary toxicity was identified. Initial symptoms were non-specific, but bronchiolitis obliterans organizing pneumonia and interstitial pneumonitis were characteristic findings by high-resolution computed tomography of the chest. The benefit of steroid therapy was uncertain and was associated with steroid-induced diabetes mellitus requiring insulin therapy in two patients. Fatal pulmonary toxicity is a major concern of a quick course NAC-VBP. In conclusion, these patients require special monitoring for bleomycin-induced pulmonary toxicity.

OBJECTIVETo investigate the efficacy and safety of photodynamic therapy (PDT) with topical 5-aminolaevulinic acid (ALA) on cervical condylomata acuminata.
METHODSPatients with cervical condylomata (n=30) were allocated into primary and recurrent group, and were given topical ALA under occlusive dressing for 3 hours followed by irradiation with semiconductor laser at a dose of 100 Jcm(-2) and a power of 100 mW. The treatment was repeated 7 days later if the lesion was not completely removed after the first treatment. Complete response rate and recurrence rate of wart lesions as well as rate of adverse reaction were analyzed.
RESULTSThe total complete response rate of PDT was 100% and the total recurrence rate was 5% after 3 months of follow-up. Recurrence rate of recurrent group was significantly lower than that of prior managements (100%, P<0.01). The side effects of PDT in patients mainly included mild burning and/or stinging restricted to the illuminated areas, and was significant lower than their own control (25% vs. 100%, P<0.05).
CONCLUSIONCompared with conventional therapies, topical application of ALA-PDT is a simple, effective, safe, well-tolerated, and low recurrence rate treatment for cervical condylomata acuminata.

OBJECTIVETo explore the therapeutic effect of acupuncture on disorders of myometrial gland and the mechanism.
METHODSSixty-six cases were randomly divided into an acupuncture group and a medication group, 33 cases in each group. The acupuncture group were treated with acupuncture at Zhongji (CV 3), Shuidao (ST 28), Tainshu (ST 25), Qugu (CV 2), Zigong (EX-CA 1) as main; the medication group were treated with oral administration of Danazol. Changes of estradiol (E2) level, hemoglobin (Hb) and blood platelet counter (BPC) were observed in the acupuncture group, and the therapeutic effects of the two group were compared.
RESULTSThe total effective rate was 97.0% in the acupuncture group and 72.7% in the medication group, the former being better than the latter (P<0.05). After treatment, E2 level decreased and Hb and BPC increased in the acupuncture group.
CONCLUSIONAcupuncture has obvious therapeutic effect, which is better than that of simple western medicine. Acupuncture can decrease E2 level.
