子痫前期患者血清微小RNAs的差异表达研究

目的探讨子痫前期患者血清微小RNAs(miRNAs)不同的表达水平,分析子痫前期相关标志物。方法选择10个子痫前期患者胎盘中差异表达的miRNA,分别收集该院30例子痫前期患者和30例正常妊娠孕妇孕早期(12~14周)、孕中期(20~24周)和孕晚期(28~32周)血清miRNAs,采用SYBR Green qRT-PCR法检测血清中10个miRNAs的表达量。结果子痫前期胎盘中高表达的3个miRNAs(miR-152、miR-183、miR-210)在子痫前期孕中、晚期血清中表达显著升高,而胎盘中高表达的miR-182仅在子痫前期孕晚期表达显著升高;子痫前期胎盘中低表达的6个miRNAs(miR-1、miR-328、miR-363、miR-377、miR-500、miR-584)在子痫前期各个孕期的表达,差异均无统计学意义(P0.05)。结论 miR-152、miR-183、miR-210在子痫前期孕中、晚期血清中表达显著升高,可能是预测子痫前期发生的良好生物标志物。     

HBsAg弱阳性及HBsAg和HBsAb同时阳性的结果分析

目的对ELISA法检测乙肝五项结果中的HBsAg弱阳性结果及乙型肝炎HBsAg和HBsAb同时阳性的结果进行分析。方法从35 280例乙肝五项ELISA法检测结果中筛出HBsAg弱阳性115例,HBsAg和HBsAb双阳性结果95例,对筛出的210例标本再进行电化学发光(ECLIA)定量检测。结果 115例HBsAg弱阳性结果用ECLIA检测,结果一致为90例。符合率为78.3%。HBsAg和HBsAb双阳性结果95例用ECLIA检测,结果一致为11例。符合率为11.6%。结论 ELISA法检测乙肝五项对HBsAg弱阳性及HBsAg和HBsAb双阳性结果要慎重。HBsAg弱阳性结果中以HBsAg、HBeAb、HBcAb阳性和HBsAg、HBcAb阳性标本占大多数。HBsAg和HBsAb同时阳性的结果可靠性差,要慎重发出报告。     

联合肝叶及入肝血管切除和重建治疗肝门部胆管癌的临床研究

目的探讨侵犯血管的肝门部胆管癌(HCCA)根治术同时联合肝叶及入肝血管切除和重建的临床意义。方法选取徐州医学院附属宿迁医院/南京鼓楼医院集团宿迁市人民医院普外科2006年1月至2014年1月期间收治的62例同时侵犯肝门部肝动脉和门静脉的HCCA患者,根据对患者手术创伤耐受程度的评估、营养状况及家属的意愿,其中33例行HCCA根治术+肝叶切除+肝动脉和门静脉联合切除重建术即R0切除(简称联合切除组),29例仅行姑息性胆管肿瘤切除和(或)内引流减黄手术即R1~2切除(简称姑息手术组)。结果联合切除组和姑息手术组患者的中位生存期分别为26.3个月和9.6个月,1、2、3年生存率分别为84.85%比26.32%、66.67%比15.79%和42.42%比0,联合切除组患者的中位生存时间和1、2、3年生存率长于或高于姑息手术组(t=4.470、P=0.000。χ2值分别为28.338、20.348和15.891,均P=0.000)。联合切除组33例患者中,术后出现并发症9例(27.27%),姑息手术组术后出现并发症5例(17.24%),2组间的差异无统计学意义(χ2=0.888,P=0.346)。联合切除组术后第12天有1例死于肝功能衰竭,围手术期死亡率为3.03%,姑息手术组围手术期无死亡者,围手术期死亡率为0,2组间的差异无统计学意义(χ2=0.893,P=0.345)。结论联合肝叶切除及血管切除重建可明显提高HCCA根治性(R0)切除率,并能提高HCCA患者的1、2、3年生存率。联合血管切除重建和联合肝叶切除的并发症是可控的,不增加围手术期死亡率。     

A Comparison of Single-, Two- and Three-Port Laparoscopic Myomectomy

Background and Objective:

A recent FDA safety communication has discouraged the use of a power morcellator for myoma extraction and has called for a change in surgical techniques for myomectomy. The objective of this study was to compare surgical outcomes of laparoscopic single-, two-, and conventional three-port myomectomy and to evaluate the feasibility of contained manual morcellation for uterine myoma.

Methods:

This retrospective study was a review and analysis of data from 191 consecutive women who underwent single-, two-, or three-port myomectomy for the management of uterine myoma from January 1, 2009, through December 31, 2014.

Results:

The 3 study groups did not differ demographically. Apart from operative time, the single- and two-port groups showed operative outcomes comparable to those of the multiport group. The single-port group had significantly longer operative times (P = .0053) than the two- and three-port groups. However, in the latter half of the single-port cases, the operative time was similar to those in the three-port group. The two-port surgery group showed a consistent operative time without a learning period.

Conclusion:

Single- or two-port myomectomy with transumbilical myoma morcellation is feasible and safe, with outcomes comparable to those of three-port myomectomy. These results suggest the potential for minimally invasive management of symptomatic uterine myoma, without the use of a power morcellator.
