Methods: 21 patients with refractory MPTC-NHL were analyzed. 11patients (L-ASP group) received L-asparaginase based salvage chemotherapy consisting of L-asparaginase, vincristine and dexame-thosone. 10 patients (control group) received salvage combination chemotherapy without L-asparaginase. Results: Complete remission rates were 45.6% for L-ASP group and 0.0% for control group (p<0.05). Overall response rates (CR+PR) were 63.6% for L-ASP group and 10.0% for control group, respectively (p<0.05). 2-year survival rates were 45.5% for L-ASP group and 0.0% for control group (p<0.05). The major adverse effects of L-ASP were leukopenia, elevation of serum bilirubin and hyperglycemia. Conclusion: The preliminary clinical study shows that the L-ASP based salvage chemotherapy may improve the response rate and 2-year survival rate of the patients with refractory MPTC-NHL. It is necessary to continue the study further.展开更多

Now, nonoperative management（NOM） is a selective method for liver trauma. The aim of this study was to determine the success rate, mortality and morbidity of NOM for isolated liver trauma.Medical records of 81 patients with isolated liver trauma in our unit were analyzed retrospectively. The success rate, mortality and morbidity of NOM were evaluated. In this series, 9 patients with grade IV-V liver injuries underwent emergent operation due to hemodynamic instability; 72 patients, 6 with grade V, 18 grade IV, 29 grade III, 15 grade II and 4 grade I, with hemodynamic stability received NOM. The overall success rate of NOM was 97.2%（70/72）. The success rates of NOM in the patients with grade I-III, IV and V liver trauma were100%, 94.4% and 83.3%. The complication rates were 10.0%and 45.5% in the patients who underwent NOM and surgical treatment, respectively. No patient with grade I-II liver trauma had complications. All patients who underwent NOM survived.NOM is the first option for the treatment of liver trauma if the patient is hemodynamically stable. The grade of liver injury and the volume of hemoperitoneum are not suitable criteria for selecting NOM. Hepatic angioembolization associated with the correction of hypothermia, coagulopathy and acidosis is important in the conservative treatment for liver trauma.展开更多

文摘目的探讨稳定型胸腰椎爆裂骨折(thoracolumbar burst fractures,TBF)非手术治疗的失败率和预测因素。方法选择2015年1月~2020年12月在该院接受非手术治疗的稳定型TBF患者资料进行回顾性分析,记录患者非手术治疗失败率。观察非手术治疗失败和非手术治疗成功患者的性别、年龄、体质量指数(body mass index,BMI)、个人史、伴随疾病、损伤原因、损伤椎体、疼痛视觉模拟评分(visual analogue scale,VAS)、椎体压缩率(vertebral body compression rate,VBCR)、椎体前缘高度压缩百分比(percentage anterior high compression,PAHC)、Cobb角、椎弓根间距(interpedicular distance,IPD)和椎管压缩程度,采用Logistic回归分析确定影响非手术治疗效果的独立因素。结果71例患者有21例非手术治疗失败,发生率29.58%。非手术治疗失败患者年龄、BMI、糖尿病、VBCR、PAHC、Cobb角、IPD、椎管压缩和VAS均高于非手术治疗成功患者(P<0.05)。多因素Logistic回归分析结果显示,年龄和IPD是影响非手术治疗效果的独立风险因素(P<0.05)。年龄预测非手术治疗失败的灵敏度、特异性、截断值和AUC分别为71.40%、86.00%、47岁、0.811,IPD预测非手术治疗失败的灵敏度、特异性、截断值和AUC分别为71.43%、88.00%、16.7%和0.771。结论年龄和IPD是影响稳定型TBF患者非手术治疗失败的风险因素,对预测手术失败具有一定临床价值。
