Objective To evaluate FIB-NLR,a combined neutrophil-lymphocyte ratio (NLR) and fibrinogen concentration (FIB) in predicting the prognosis of gastrointestinal stromal tumors (GIST).Methods Data of 79 GIST patients who underwent surgery from Jun 2010 to Dec 2014 were retrospectively analyzed.Patients were divided into 3 groups:NLR ＜ 2.30 and FIB ＜ 3.85 g/L were defined as group 0,NLR≥2.30 and FIB ＜3.85 g/L or NLR ＜2.30 and FIB≥3.85 g/L as group 1,NLR≥2.30 and FIB≥3.85 g/L as group 2.The clinicopathological features of the three groups and the 5-year recurrence-free survival rate after surgery were compared.Results FIB concentration and NLR were significantly correlated with NIH risk grade and tumor size in GIST patients (x2 =9.517,12.41 1,6.081,20.067,all P ＜ 0.05).FIB-NLR was closely related to tumor size,tumor risk and tumor mitosis (x2 =14.406,12.514,28.225,all P ＜ 0.05).Survival analysis showed that high FIB predicts lower 5-year recurrence-free survival rate,it was 87.4％ for group 0,60.8％ for group 1,21.1％ for group2,x2 =29.617,P＜0.000).Conclusion FIB-NLR independently predicts the prognosis of gastrointestinal stromal tumors.

Objective To investigate the impact of preoperative abdominal aortic balloon occlusion and modified uterine vascular occlusion on repeat cesarean delivery in patients with placenta previa and placenta accreta spectrum disorders.Methods A total of 97 patients with placenta previa and placenta accreta spectrum disorders who underwent repeat cesarean section at Hefei Maternal and Child Health Hospital between April 2016 and Decem-ber 2022 were included in this study.Among them,the control group consisted of 48 cases who underwent abdominal aortic balloon occlusion before the operation,while the observation group comprised 49 cases who underwent modified uterine vascular occlusion during the operation.Intraoperative and postoperative complications were observed and compared between the two groups.Results The number of bilateral uterine artery embolization post-operation and the average hospitalization cost in the observation group were significantly lower compared to those in the control group(P<0.05).However,there were no significant differences observed between the two groups regarding average intraoperative blood loss,red blood cell suspension transfusion volume,hysterectomy rate,and bladder rupture rate(P>0.05).Conclusions Both surgical methods effectively reduce intraoperative bleeding in the treatment of repeat cesarean section in patients with placenta previa and placenta accreta spectrum disorders.However,modified uterine vascular occlusion demonstrates no complications related to vascular intervention or X-ray exposure,ensuring high maternal and child safety while significantly reducing hospitalization costs.Therefore,it is highly recommended for clinical promotion.
