RESUMEN
Objective To investigate value of peripheral NLR and PLR for the survival of patients with neuroblastoma.Methods The clinical data of 41 neuroblastoma patients were analyzed by the Kaplan-Meier,Log-rank test,and multivariate COX regression.Results NLR,PLR levels of neuroblastoma patients were significantly higher than that in the healthy control group (1.81 ±0.29 vs.1.07 ±0.29,P ＜ 0.01) (169 ± 23 vs.76 ± 3,P ＜ 0.01);The elder the age,the higher the clinical stages,the higher the serum levels of NSE,and urine VMA were,the higher was the NLR (x2 =3.93,6.286,7.676,6.689,all P＜0.05) and PLR (x2 =4.111,5.707,8.019,8.922,all P ＜0.05).The higher the serum level of LDH,the higher was the NLR (x2 =7.769,P =0.02).3-year overall survival in low NLR group was 84％ and that in high NLR group was 73％ (x2 =4.002,P =0.045);3-year progression-free survival in low NLR group was 74％ and that in high NLR group was 50％ (x2 =4.082,P =0.043);3-year progression-free survival of low PLR group was 85％ and high PLR group was 38％ (x2 =9.388,P =0.002).The clinical stages,MYCN genetic expression,NLR levels were independent factors for the overall survial in patients with neuroblastoma (P ＜ 0.05).Conclusion Pretreatment NLR level can effectively predict the prognosis of neuroblastoma.
RESUMEN
Objective:To evaluate the efficacy of allicin combined with cyclophosphamide on neuroblastoma (NB)-bearing mice and explore the immunological mechanism in it.Methods:A total of30 NB-bearing mice were equally randomized into model group, cyclophosphamide group and combined therapy group,10 nudemice were set as normal saline(NS) group.Cyclophosphamide group and combined therapy group were weekly injected with60 mg/kg cyclophosphamide for four weeks; besides, combined therapy group was given with allicin(10 mg/kg/d) by gastric perfusion for4 weeks; model group and NS group were given with the same volume of NS.Serum VEGF content was detected byELISA pre-treating(0 d) and on the3rd d,14th d and28th d; on 29th d, all mice were sacrificed and the tumor, liver, spleen and thymic tissues were weighted. Tumors were made into paraffin section for detecting tumor cell apoptosis and proliferation by TUNEL and BrdU method, respectively.Survival curves were drawn byKaplan-Meier method. Results:After treatment, both treatment groups relieved on viscera indexes,VEGF level,T cell subsets distribution and tumor growth and each index of combined therapy group was better than cyclophosphamide group(P<0.05 or0.01); only combined therapy group could significantly increase the lifetime of NB-bearing mice(χ2=5.667,P=0.017).Conclusions:Allicin can improve T cell subsets distribution and inhibitVEGF expression through its immunomodulatory activity, thereby improve the efficiency onNB in coordination with cyclophosphamide.
RESUMEN
Objective To investigate the clinical diagnosis and treatment of children's relapsesable intussusception by Peutz-Jeghers syndrome.Methods 5 cases of relapsesable intussusception result from Peutz-Jeghers syndrome which confirmed by operation and pathological diagnosis in children were analyzed retrospectively.Results All patients were diagnosed definitely by operation and pathological diagnosis and recovered well postoperatively.Conclusions Treated with the intussusception and resected polypus is effect to Peutz-Jeghers syndrome because it caused intussusception recurred easily,and patients should be followed up and examined regularly.
RESUMEN
Objective To evaluate the clinical value of laparoscopy in the diagnosis and treatment of intestinal duplication for children. Methods From June 2002 to May 2007, 15 children (aged 27 days to 10 years) with intestinal duplication were treated by laparoscopy in our hospital. The lesions were explored by laparoscopy, and then pulled out through the umbilical hole or the trocar hole at the right lower abdomen. The anastomosis was performed outside the abdominal cavity. Results The operation was successfully accomplished in all the patients. No serious postoperative complications occurred. Among the cases, end-to-end anastomosis was performed on 12 patients, resection of the duplicated intestine on 2, and demucosation on 1. Simultaneously, appendectomy was performed on 2 cases, and ring suturing for inguinal hernia on 1. The patients were followed up for 3-18 months (mean, 12 months), during which no patients had symptoms of intestinal adhesion (abdominal distension, vomiting), hemorrhage, or incisional hernia. Conclusions Laparoscopy is effective and reliable with a high diagnostic rate and low complication rate in the diagnosis and treatment of intestinal duplication for children.
