ABSTRACT
Objective:To evaluate the effect of resveratrol combined with γ-ray irradiation on the biological behavior of cervical cancer cells, and to explore its possible mechanism.Methods:The proliferation of cell populations after different concentrations of resveratrol solution±γ-ray irradiation was detected by CCK-8 assay. Scratch test and Transwell chamber test were used to detect cell migration and invasion. Flow cytometry and Annexin V-FITC/PI double staining were employed to assess cell apoptosis. Western blot was performed to measure the expression levels of PI3K, Akt, p-Akt, mTOR and p-mTOR proteins.Results:Compared with the normal control (NC) group, the resveratrol group±γ-ray irradiation could inhibit the proliferation, migration, and invasion and promote cell apoptosis of human cervical cancer Hela cells, and the combined effect was more obvious. Compared with the NC group, resveratrol and γ-ray irradiation could significantly down-regulate the expression levels of Bcl-2, PI3K, p-Akt and p-mTOR proteins, up-regulate the expression level of Bax protein, but did not significantly alter the expression levels of Akt and mTOR proteins in human cervic1 255al cancer Hela cells.Conclusions:Resveratrol combined with γ-ray irradiation can dramatically inhibit the proliferation, migration, invasion, and promote the apoptosis of cervical cancer Hela cells. The mechanism may be related to the inhibition of the PI3K/Akt/mTOR signaling pathway and down-regulating the expression levels of downstream related proteins.
ABSTRACT
Objective To investigate the clinical value of uterine artery embolization on the treatment of cesarean scar pregnancy(CSP).Methods Clinical data of 112 cases of CSP patient underwent uterine artery embolization in Ningbo Women and Children's Hospital from January to December 2012 were enrolled for retrospectively analysis.Results All 112 patients underwent transvaginal ultrasound examination before admitted to hospital and among them 101 cases were diagnosed as CSP and 11 cases were suspected of CSP.Ninety-four cases were checked by magnetic resonance imaging (MRI) to measure the muscular thickness of uterine scar and the size of pregnant bursa.All patients received bilateral uterine artery embolization successfully,50-100 mg Methotrexat (MTX) were injected into uterine artery during this procedure.After uterine artery embolization,95 cases received curettage under ultrasound guidance,while 17 cases received curettage under hysteroscopy.All patients recovered as schedule.During the follow-up,no serious complication was found.Conclusion The use of uterine artery embolization in the treatment of CSP is safe and effective,and it can preserve patients' fertile ability.It is worthy recommended in the clinical application.
ABSTRACT
Objective To investigate blocking ascending branch of uterine arteries in operation of hysteromyomas rejecting by laparoscope.Methods 60 petients(except cervix myoma,intraligamentary myoma,submucosa myoma),randomly devided to reseach group(30 cases)and control group(30 cases).Blocking ascending branch of uterine arteries before rejecting hysteromyomas by laparoscope in reseach group,directly rejecting hysteromyomas by laparoscope in control group.The volumes of blood loss in operation,the duration of operation,postoperative recovery(Time of passing flatus,wound healing,length of stay)were compared between two groups.During the follow-up months,observing hysteromyoma recidivism and improvement of menstruation.Results All patient were rejected hysteromyomas by laparoscope.The volumes of blood loss in research group were less than that in control group(P0.05),All wounds were well healed in both groups,the rate of hypermenorrhea improvement was 100%(26/26)in research group,but That in control group was 80%(16/20),There was significant difference between two group.Conclusions Blocking ascending branch of uterine arteries may obviously decrease the volumes of blood loss in operation of hysteromyomas rejecting by laparoscope,It presents rapider convalescence,higher rate of symptom improvement and less complication operation.
