RESUMEN
Objective:To analyze the clinicopathological features of giant ovarian masses(mean diameter≥10 cm)and analyze the clinical characteristics of patients in different age groups.Methods:The clinicopathological characteristics of 311 patients diagnosed with giant ovarian masses by surgery at Nanjing Drum Tower Hospital,Affiliated Hospital of Medical School,Nanjing University from January 2014 to December 2022 were retrospectively analyzed.Patients were further stratified by age and mass size to compare the differences of clinical and patho-logical features among different age groups and different mass diameter groups.Results:①The median age of thepatients were 44(24,60)years old.The first symptoms were as follows:ovarian mass discovered during physi-cal examination,abdominal pain,bloating,conscious abdominal distension,and symptoms of compression.②The surgical methods were as follows:unilateral oophorectomy(30.5％,95/311),ovarian cystectomy(28.9％,90/311),tumor staging or cytoreductive surgery(28.0％,87/311),total hysterectomy with bilateral adnexectomy(12.5％,39/311).③The pathological types were benign(49.5％,154/311),malignant(31.8％,99/311)and borderline(18.7％,58/311).④ Patients complained abdominal distension in＜20 years old group were signifi-cantly higher than the other two groups(P＜0.05).The ovarian resection rate in the＞50-year-old group was higher than that of the other two groups(P＜0.05),and the rate of unilateral ovarian resection in the＜20-year-old group was still as high as 30.1％(15/49).⑤ The size of the mass correlated with the duration of the disease.When the disease course was between 1 to 6 months,the mass diameter line＞30 cm was the most common(P＜0.05).The incidence of borderline tumors in the＞30 cm group was significantly higher than that in the other two groups,and the difference was statistically significant(P＜0.05).Conclusions:Ovarian mucinous and mucinous borderline tumors are the most common types of giant adnexal masses.The size of the mass tends to increase with the prolongation of the disease course.The incidence of borderline tumors increases with the in-crease of mass.Health education for young people should be strengthened.When abdominal pain,abdominal bloating,especially lower abdominal distension occurs,they should seek medical treatment in time to avoid adnex-ectomy due to borderline tumors.
RESUMEN
Objective To preliminarily investigate the effect of ribosomal protein S7 on apoptosis of HeLa cervical cancer cells.Methods The previously constructed recombinant plasmid pIRES2-EGFP-RPS7 was transfected into HeLa cells,the empty vector pIRES2-EGFP transfected cells as control.Enhanced green fluorescent protein(EGFP)expressing cells were quantified by flow cytometry,and RPS7 protein level was also determined by Western blotting.Cell apoptosis of both RPS7 over-expression cells and knockdown cells were evaluated by flow cytometry after staining using allophycocyanin labeled Annexin-V.Results Apoptotic cell level in the obtained RPS7 transient over-expression HeLa cells was significantly higher than that of vector con-trol cells [(1 0.00 ±0.60)% vs (5.73 ±0.61 )%],with a statistic difference (t =8.63,P =0.001 ). Moreover,the apoptotic level in RPS7 knockdown cells was lower than that in control cells [(3.08 ± 0.49)% vs (5.97 ±0.63)%],with a statistic difference (t =6.40,P =0.003).Conclusion Up-regula-tion of RPS7 may promote apoptosis,while down-regulation of RPS7 may inhibit apoptosis of HeLa cells,indi-cating that RPS7 may play roles in regulating cell apoptosis.
RESUMEN
Objective To compare the effectiveness and safety of Foley catheter(FC)and vaginal prostaglandin E2 suppository(PGE2,Propess)for cervical ripening and labor induction in fullterm pregnant women with unfavorable cervix.Methods A prospective randomized controlled trial was conducted.Women with a term or post-term,live,singleton fetus in cephalic presentation,intact membranes,Bishop score＜6,not in labor,medically indicated for labor induction from June 2009 to December 2009 in Drum Tower Hospital of Nanjing University Medical School were randomly divided into two groups:FC group(n=64)and Propess group(n=62).In FC group,a 16-F Foley catheter was inserted into patient's cervical canal; once past the internal os,the balloon was inflated with 80 ml saline.Intravenous oxytocin was initiated after the balloon was spontaneously extruded from the cervix or after 24 hours.In Propess group,vaginal Propess was used.x2 or Fisher's exact test and t test were used to compare the outcomes,delivery mode and induction success rate between the two groups.Results There were no significant differences in gestational weeks,Bishop score,indication of induction,improvement of Bishop score,success rate of induction,rate of vaginal delivery,total duration of labor and volume of postpartum hemorrhage between the two groups(P ＞ 0.05,respectively).Propess group had a higher rate of vaginal birth within 24 hours[56.5％(35/62)vs 28.1％(18/64),t=10.37,P＜0.05],a higher risk for excessively frequent and hard uterine contraction[17.7％(11/62)vs 0.0％(0/64),P＜0.05]and lower incidence of oxytocin induction/augmentation during labor[21.0％(13/62)vs 87.5％(56/64),x2 =56.27,P＜0.05]than those of FC group.There were no differences in neonatal Apgar score,meconium staining and neonatal birth weight between the two groups.Puerperal infection occured in neither group.Conclusions Under strict control of indication and aseptic manipulation,Foley catheter was as effective and safe as Propess for cervical ripening with lower risk of excessive uterine activity.It is suggested that Foley catheter could be used for cervical ripening,especially in patients with economic difficulty.
