    • 摘要: 目的 通过荟萃分析探究肝细胞癌自发性破裂出血患者的最佳手术治疗策略.方法 系统检索PubMed、Web of Science、Embase以及Cochrane Library数据库,通过纳入和排除标准筛选出比较急诊肝部分切除(ER)和经肝动脉栓塞术后二期手术(SH)的合格研究,并使用Review Manager 5.3软件对报告的围手术期指标和生存数据进行统计汇总及分析.结果 共纳入8篇回顾性研究,总样本量556例,其中ER组285例(51.3%),SH组271例(48.7%).荟萃分析结果显示,SH组的围手术期失血量(WMD=683.61,95% CI:283.36~1083.86,P=0.0008)及输血量(WMD=453.43,95% CI:250.27~656.58,P<0.0001)均少于ER组,差异有统计学意义;两组之间的手术时间、并发症发生率、病死率以及肿瘤复发率差异无统计学意义(均P>0.05).ER组的1、2、3年总生存率和1、2、3、5年无病生存期与SH组比较差异无统计学意义(均P>0.05),但ER组5年总生存率低于SH组(HR=1.52,95% CI:1.14~2.03,P=0.005).结论 ER或SH在治疗肝癌破裂出血的近期疗效方面无明显差别,SH在远期生存方面优于ER.

    • 摘要: 目的 探讨初诊破裂出血肝癌的治疗策略选择及影响预后的相关因素.方法 回顾性分析2012年1月至2016年12月,107例初诊不可切除的肝癌自发破裂出血患者治疗的临床资料.治疗方式包括保守治疗,肝动脉栓塞术,外科止血及分期肝切除术.采用Kaplan-Meier法计算累积生存率,Cox回归模型分析生存预后因素.结果 107例患者,中位生存期为135 d,6个月、1年、2年和3年的累积生存率分别为44%、32%、19%和16%.多因素Cox回归分析显示:肿瘤直径(P=0.020)、Child-Pugh评分(P=0.018)、改良日本肝癌学组(LCSGJ)分期(P<0.001)以及治疗方式(P<0.001)是患者预后的独立相关因素.结论 本研究显示,对于初诊肝癌破裂出血患者,较大的肿瘤直径,较差的Child-Pugh评分及较晚的改良LCSGJ分期与患者预后不良有关;而发病初期积极介入栓塞等止血治疗联合分步肝切除能显著改善部分患者的预后.

    • 摘要: 从弹性动力学方程出发模拟了鲁甸地震在包谷垴—小河断裂地震自发破裂过程,探讨影响鲁甸地震破裂的因素.研究结果表明:鲁甸地震的左旋走滑的震源机制以及震级主要是受背景应力场的影响,断层滑移分布受到断层几何结构、水平应力场方向及相对大小的影响,非平面复杂断层几何结构是导致鲁甸地震复杂的滑动位移分布的原因.

    • 摘要: Objective:To identify the risk factors for early mortality (≤30 days) in patients with ruptured naive hepatocellular carcinoma (HCC), including treatment modality. Methods:Between Jun 2012 and Dec 2016, the medical records of 80 ruptured naive HCC patients who received conservative treatment or transarterial embolization (TAE) as initial therapy from the authors' affiliated hospital were retrospectively analyzed. According to the survival state within 30 days, the selected patients were divided into the survival group and the dead group. An independent sample t-test was used for the continuity variables between the two groups, and the constituent ratios and rates were tested using the χ2 test. The possible risk factors related to early mortality were analyzed by using univariate and multivariate logistic regression model (P< 0. 05). Results:Of 80 patients, the early mortality was 28. 8%. Univariate analysis showed that the proportion of patients with shock on admission (P=0. 008), conservative treatment (P< 0. 001), poor Child-Pugh class (P< 0. 001) and advanced modified tumor stage of the liver cancer study group of Japan (LCSGJ) (P< 0. 001) in the dead group was significantly higher than those in the survival group, and the patients' initial hemoglobin level of the dead group (P< 0. 001) was also significantly lower than that of the survival group. Multivariate Logistic regression analysis indicated that patients with shock on admission (OR=5. 543, P=0. 026), poor Child-Pugh class[class B (OR=10. 395, P=0. 009) and class C (OR=23. 633, P=0. 006) ]and conservative treatment (OR=8. 576, P=0. 002) were independent risk factors for early mortality. Conclusion:Among ruptured naive HCC patients, the early mortality is high. For such patients, actively correcting shock while improving liver function as early as possible should undoubtedly have great significance for improving the prognosis. Additionally, reasonably expanding the indications of interventional therapy is essential.%目的:探讨初诊肝癌合并自发破裂出血患者早期死亡(生存期≤30 d)的危险因素及治疗方式的选择.方法:回顾性分析南京医科大学第一附属医院2012年6月—2016年12月,80例接受保守治疗或选择性动脉栓塞治疗的初诊肝癌自发破裂出血患者,根据患者30 d生存状态分成生存组及死亡组.两组间连续性变量采用独立样本t检验,构成比和率采用χ2检验,并将单因素分析阳性因素代入多变量Logistic回归模型,分析患者早期死亡的独立危险因素.结果:80例患者,早期病死率为28.8%.单因素分析显示死亡组患者休克比例(P=0.008)、初诊保守治疗比例(P<0.001)、Child-Pugh分级(P<0.001)、改良日本肝癌学组(LCSGJ)肿瘤分期(P<0.001)明显高于生存组,死亡组患者初始血清血红蛋白水平(P<0.001)明显低于生存组.多变量Logistic回归分析显示休克史(OR=5.543,P=0.026)、Child-Pugh分级较高[B级(OR=10.395,P=0.009)、C级(OR=23.633,P=0.006)]、初诊保守治疗(OR=8.576,P=0.002)是患者早期死亡的独立危险因素.结论:初诊肝癌合并破裂出血患者早期病死率高.在积极抗休克、尽可能挽救患者肝功能储备的同时,合理扩大介入治疗的适应证,可能为患者生存带来更多获益.

    • 摘要: 首先利用地震地质调查、地震剖面探测结果对汶川地震的发震断层几何形态及周边块体介质参数进行约束,建立了3个包含有不同主断层的龙门山断裂带二维黏弹性有限元模型;然后基于连续-离散单元法对汶川地震的孕育与发生进行了全周期模拟,包括震间应力积累阶段、同震应力释放阶段及震后恢复调整阶段.模型对比研究结果表明,龙门山断裂带中由于断层几何结构及断层面剪切应力与正应力的综合作用,使得最先达到断层破裂准则阈值的灌县-江油断层率先破裂,初始破裂在深度15~20km处,破裂进一步传导至映秀-北川断层;同时由于灌县-江油断层与映秀-北川断层的破裂导致系统内应力大幅度降低,使得灌县-江油断层不具备产生同震破裂的应力条件.然而,尽管汶川-茂汶断层上的应力水平与汶川地震前相比有所减弱,但仍积累了较高的震间应力,可能预示其在汶川地震后具有较高的地震危险性.模拟结果还表明,铲型逆冲断层系统的深部断层破裂能够推动浅部高倾角区域发生被动破裂,因而其发震断层的倾角上限很可能比传统认识的大.%The May 12,2008 MS7.9 Wenchuan earthquake is ranked as one of the most devastating natural disasters ever occurred in modern Chinese history.The Longmenshan Fault(LMSF)zone is the seismogenic source structure,which consists of three sub-parallel faults,i.e.,the Guanxian-Jiangyou Fault(GJF)in the frontal,the Yingxiu-Beichuan Fault(YBF)in the central fault and the Wenchuan-Maowen Fault(WMF)in the back of the LMSF.In this study,geological survey and seismic profiles are used to constrain the faults geometry and medium parameters.Three visco-elastic finite element models of the LMSF with different main faults are established.From the phase of interseismic stress accumulation to coseismic stress release and postseismic adjustment,the Wenchuan earthquake is simulated using Continuous-Discrete Element Method(CDEM).Modeling results show that before the 2008 Wenchuan earthquake,the GJF becomes unstable due to the interaction between its unique fault geometry and the tectonic stress loading.In the fault geometry model,the GJF is the most gently dipped fault among the three faults,which in return makes it having the smallest normal stress and the greatest shear stress.The continuous shear stress loading finally meets the fault failure criteria and the Wenchuan earthquake starts to initiate on the GJF at the depth of 15~20km.The earthquake rupture then propagated to the YBF.At the same time,due to the GJF and YBF rupture,the interseismic stress accumulation has been greatly reduced,causing the WMF failed to rupture.Although the stress accumulation in the WMF has been reduced significantly after the earthquake,yet it has not been released completely,which means that the WMF likely has with high seismic risk after the 2008 Wenchuan earthquake.We also find that the stress perturbation caused by gently dipping segment of the fault can promote the passive rupture in the steeply dipping segment,making the upper limit of dip angles larger than traditional assumption.
