目的探讨2010—2017年中国胆囊癌临床流行病学特征、诊断、治疗与预后情况。方法采用单病种回顾性登记队列研究方法。基于“真实世界研究”理念,收集2010年1月至2017年12月中国胆囊癌研究小组(CRGGC)建立的中国胆囊癌多中心回顾性临床资料数据库中42家医院收治的6159例胆囊癌患者的临床病理资料。观察指标:(1)病例来源情况。(2)年龄与性别分布情况。(3)诊断情况。(4)外科治疗与预后情况。(5)综合治疗与预后情况。随访数据由CRGGC对各协作中心的临床随访数据进行收集整理,主要结局指标为手术治疗患者手术之日或未手术患者确诊之日起,至结局事件发生或随访截至时间的总体生存时间。正态分布的计量资料以x±s表示,组间比较采用t检验;偏态分布的计量资料以M(Q1,Q3)或M(范围)表示,组间比较采用U检验。计数资料以绝对数和(或)百分比表示,组间比较采用χ^(2)检验。单因素分析采用强迫引入Logistic回归模型,将P<0.1的因素引入多因素分析。多因素分析采用逐步后退Logistic回归模型。采用寿命表法计算生存率,采用Kaplan-Meier法绘制生存曲线,采用Log-rank检验进行生存分析。结果(1)病例来源情况:42家医院中,三级甲等医院35家,三级乙等医院7家;胆囊癌收治高流量医院16家,非高流量医院26家。42家医院地域分布:中部地区9家,东北地区5家,东部地区22家,西部地区6家。6159例患者地域分布:2154例(34.973%)来自中部地区,705例(11.447%)来自东北地区,1969例(31.969%)来自东部地区,1331例(21.611%)来自西部地区。6159例患者总体院均诊断与治疗数为(18.3±4.5)例/年;其中4974例(80.760%)来源于高流量医院,院均诊断与治疗患者数为(38.8±8.9)例/年;1185例(19.240%)来源于非高流量医院,院均诊断与治疗患者数为(5.7±1.9)例/年。(2)年龄与性别分布情况:6159例患者确诊年龄为64(56,71)岁;其中男性2247例(36.483%),确诊年龄为64(58,71)岁;女性3912例(63.517%),确诊年龄为63(55,71)岁。性别比例为女性:男性=1.74∶1。3886例(63.095%)患者确诊年龄为56~75岁。不同性别患者确诊年龄比较,差异有统计学意义(Z=-3.99,P<0.001)。(3)诊断情况:6159例患者中,初步诊断为胆囊癌2503例(40.640%),初步诊断非胆囊癌3656例(59.360%)。未手术患者2110例(34.259%),其中初步诊断为胆囊癌200例(9.479%),初步诊断为非胆囊癌1910例(90.521%)。手术患者4049例(65.741%),其中初步诊断为胆囊癌2303例(56.878%),初步诊断为非胆囊癌1746例(43.122%)[术中诊断为胆囊癌774例(19.116%)、术后诊断为胆囊癌972例(24.006%)]。6159例患者中,初步诊断前行超声、CT、磁共振成像(MRI)检查分别为2521例(40.932%)、2335例(37.912%)、1114例(18.087%),行血清癌胚抗原(CEA)、CA19-9、CA125检测分别为3259例(52.914%)、3172例(51.502%)、4016例(65.205%)。同一例患者可行多种检查。单因素分析结果显示:来源医院地区(东部地区、西部地区),年龄(≥72岁),收治医院胆囊癌患者流量,初步诊断前超声检查,初步诊断前CT检查,初步诊断前MRI检查,初步诊断前CEA检测,初步诊断前血清CA19-9检测,初步诊断前血清CA125检测均是影响胆囊癌患者初步诊断为胆囊癌的相关因素(优势比=1.45、1.98,0.69,0.68,2.43,0.41,1.63,0.41,0.39,0.42,95%可信区间为1.21~1.74、1.64~2.40,0.59~0.80,0.60~0.78,2.19~2.70,0.37~0.45,1.43~1.86,0.37~0.45,0.35~0.43,0.38~0.47,P<0.05)。多因素分析结果显示:来源医院地区(东部地区、西部地区),性别,年龄(≥72岁),收治医院胆囊癌患者流量,初步诊断前超声检查,初步诊断前CT检查,初步诊断前血清CA19-9检测是影响胆囊癌患者初步诊断为胆囊癌的独立影响因素(优势比=1.36、1.42,0.89,0.67,1.85,1.56,1.57,0.39,95%可信区间为1.13~1.64、1.16~1.73,0.79~0.99,0.57~0.78,1.60~2.14,1.38~1.77,1.38~1.79,0.35~0.43,P<0.05)。

在兰州重离子研究装置的放射性束流线(HIRFL-RIBLL1)上,使用由三块双面硅微条探测器及环绕它的五个高纯锗探测器组成的探测器阵列,对丰质子核^(29)S的延迟衰变性质展开研究。本次实验获得了^(29)S的半衰期,为183(4)ms。首次实现了^(29)S的延迟测量,准确地获得了4条射线,得到了通过衰变布居到子核^(29)P低激发态的衰变分支比,并由此建立了^(29)S的部分衰变纲图。基于实验数据,研究了^(29)S→^(29)P/^(29)Al→^(29)Si镜像衰变过程中的同位旋对称性破缺。

Using data taken at 29 center-of-mass energies between 4.16 and 4.70 GeV with the BESⅢdetector at the Beijing Electron Positron Collider corresponding to a total integrated luminosity of approximately 18.8 fb^(-1),the process e^(+)e^(-)→pppñπ+*** observed for the first time with a statistical significance of 11.5σ.The average Born cross sections in the energy ranges of(4.160,4.380)GeV,(4.400,4.600)GeV and(4.610,4.700)GeV are measured to be(21.5±5.7±1.2)fb,(46.3±10.6±2.5)fb and(59.0±9.4±3.2)fb,respectively,where the first uncertainties are statistical and the second are *** line shapes of the pñ and ppπ^(-)invariant mass spectra are consistent with phase space distributions,indicating that no hexaquark or di-baryon state is observed.
