Background There are few reviews on the clinical features and prognosis of young patients with papillary thyroid cancer and bilateral cervical metastases. We have investigated the long-term impact of initial surgical and medical therapy on such patients. Methods A retrospective study was performed on 24 young patients （11 females and 13 males） with papillary thyroid cancer and bilateral cervical lymph node metastases, ranging in age from 11 to 20 years （mean age, 16.6 years）, who were treated in our institution from 1 January 1970 to 31 December 1985. Results All the patients in this group were followed up for 20 years. The survival of the patients at 20 years was 91.7%. The recurrence of local tumor and distant metastases was 20.8% and 12.5%, respectively. Based on analysis of the clinical data, we determined that the completeness of the surgical excision had a significant correlation with tumor recurrence. Conclusion These young patients with papillary thyroid cancer and cervical metastases have a good prognosis after suitable treatment.

目的寻找临床颈侧区淋巴结阴性（cN0）甲状腺乳头状微癌（PTMC）患者Ⅵ区淋巴结转移的风险因素。方法回顾分析2005年11月至2007年1月初治的86例颈侧区cN0 PTMC患者的资料，探讨与PTMCVI区淋巴结转移相关的临床病理因素。结果86例PTMC患者中Ⅵ区淋巴结转移率为46．5％（40／86）。单因素分析发现肿瘤最大径（≥5mm）、甲状腺包膜或包膜外侵犯、Ⅵ区淋巴结最大径（≥4mm）与PTMCⅥ区淋巴结转移显著相关（P〈0．05）；logistic回归模型多因素分析发现仅肿瘤最大径（≥5mm）、甲状腺包膜或包膜外侵犯为PTMCⅥ区淋巴结转移的独立预测因子（P〈0．05）。结论颈侧区cN0的PTMC中原发灶大小（≥5mm）、甲状腺包膜或包膜外侵犯与肿瘤Ⅵ区淋巴结转移显著相关。对于病理证实的PTMC，特别对于肿瘤最大径≥5mm或者病灶位于浅表与周围组织粘连甚至侵犯者需常规行Ⅵ区淋巴结清扫。

背景与目的:甲状腺特别是甲状腺癌手术常会意外切除甲状旁腺(inadvertent parathyroidectomy,IPE),而IPE可能会影响患者的钙磷代谢。本研究试图分析甲状腺癌手术中甲状旁腺意外切除的风险因素。方法:回顾分析2004-2007年头颈外科实施单侧甲状腺手术的418例甲状腺癌患者,收集相关临床病理资料进行统计学分析。研究患者性别、Ⅵ区清扫、肿瘤大小、病理类型、肿瘤外侵、伴发甲状腺炎与IPE的相关性。结果:甲状腺癌患者中IPE发生率为22.5%(94/418),所有患者均未出现永久性低钙血症。在与IPE相关的单因素及多因素分析中仅Ⅵ区清扫差异有显著性(P<0.001;P=0.02),相对危险度为11.90。患者性别、肿瘤大小、病理类型、肿瘤外侵、伴发甲状腺炎在单因素及多因素分析中均未发现差异有显著性。结论:单侧甲状腺癌手术中,Ⅵ区清扫是IPE的风险因素,必须掌握Ⅵ区清扫指征,掌握保护旁腺手术技巧。

To verify the performance of the neutron total cross-sectional spectrometer, the neutron total cross section of carbon is initially measured in the energy range of 1 eV to 20 MeV using the time-of-flight method. The measurement is performed at the Back-n white neutron source with a 76-m time-of-flight path using the China Spallation Neutron Source. A multilayer fast fission chamber with 235U and 238U is employed as the neutron detector. The diameter and thickness of the natural graphite sample are 70 mm and 40 mm, respectively. Signal waveforms are collected using a data acquisition system. Off-line data processing was used to obtain the neutron time-of-flight spectra and transmissions. The uncertainty of the counting statistics is generally approximately 3% for each bin in the energy range of 1–20 MeV. It is determined that the results for the neutron total cross section of carbon obtained using ^235U cells are in good agreement with the results obtained using 238U cells within limits of statistical uncertainty. Moreover, the measured total cross sections show good agreement with the broadening evaluated data.
