HIF-1α在子宫内膜异位症中的研究进展

子宫内膜异位症(Endometriosis,EMs)是育龄妇女的常见病,但其发病机制至今仍不清楚。越来越多的证据表明,低氧与EMs发生发展有密切的联系。在EMs异位组织中低氧诱导因子-1α(HIF-1α)的表达明显增高;HIF-1α通过调节雌激素产生、血管生成、细胞增殖和炎症等相关基因,促进EMs发展;HIF-1α是EMs有氧糖酵解过程中关键的调节因子;抑制HIF-1α的表达有助于抑制EMs的发生发展,表明HIF-1α在EMs的病理形成中的作用。本文介绍HIF-1α的研究进展,着重论述其在EMs中的作用。     

Adenomyosis — an unusual cause of sciatic pain

Summary We report the case of a female patient who presented with a 5-month history of sciatic pain. She was referred to us for investigation and eventual surgical treatment of a suspected herniated lumbar intervertebral disc. Because of an ill-defined clinical picture at admission, she was treated conservatively. After 2 weeks without any improvement, imaging of the spine by MR was performed. No signs of a herniated disc or intraspinal, space-occupying lesion were apparent, but a right paramedian pelvic mass was seen. Ultrasonography confirmed an enlarged, irregular uterus. Hysterectomy abolished the symptoms.

Acute small bowel obstruction caused by endometriosis：A case report and review of the literature

Gastrointestinal involvement of endometriosis has been found in 3%-37% of menstruating women and exclusive localization on the ileum is very rare（1%-7%）.Endometriosis of the distal ileum is an infrequent cause of intestinal obstruction,ranging from 7% to 23% of all cases with intestinal involvement.We report a case in which endometrial infiltration of the small bowel caused acute obstruction requiring emergency surgery,in a woman whose symptoms were not related to menses.Histology of the resected specimen showed that endometriosis was mainly prevalent in the muscularis propria and submucosa and that the mucosa was not ulcerated but had inflammation and glandular alteration.Endometrial lymph node involvement,with a cystic glandular pattern was also detected.     

子宫内膜癌合并子宫内膜异位症的临床病理分析

目的通过对子宫内膜癌合并子宫内膜异位症的临床病理分析,探讨子宫内膜异位症和子宫内膜癌的内在联系。方法将2011年3月～2012年9月在我院治疗过的患有子宫内膜癌合并子宫内膜异位症的病例数34例作为组1．同时将患有子宫内膜癌但未合并子宫内膜异位症的78例作为组2,将仅患有子宫内膜异位症的44例作为组3。根据临床病理特征和年龄分布从而对三组进行对照分析。结果组1和组3的病理分期相对于组2的病理分期均较低,且患者年龄均趋向于年轻化,三组的年龄分布以及手术病理分期经比较,差异有统计学意义（P〈0．05）。结论当病例同时患有子宫内膜异位症时,病例趋向于年轻化,子宫内膜癌的病理分期较早,细胞分化较高同时肌层浸润浅,病情恢复快。     

Genetic contribution of tumor necrosis factor (TNF)-alpha gene promoter (-1031, -863 and -857) and TNF receptor 2 gene polymorphisms in endometriosis susceptibility

PROBLEM: Tumor necrosis factor (TNF)-alpha is a major cytokine involved in inflammatory and immune function. The aim of this study was to investigate whether polymorphisms at positions -1031, -863 and -857 in the TNF gene promoter region (TNFA) and TNF receptor type 2 gene (TNFR2) are responsible in part for genetic susceptibility to endometriosis. METHODS OF STUDY: TNFA and TNFR2 polymorphisms were determined in 123 patients with endometriosis and 165 fertile healthy women by the polymerase chain reaction (PCR) - preferential homoduplex formation assay and PCR-restriction fragment length polymorphism, respectively. RESULTS: The frequency of the TNFA-U01 haplotype was increased significantly in patients with endometriosis compared with controls (P = 0.045, OR = 1.45). The TNFA-U01 haplotype was strongly associated with HLA-B*0702. No difference was found in TNFR2 polymorphism between patients and controls. CONCLUSION: Our results indicated that TNFA promoter polymorphism was associated with susceptibility to endometriosis. However, this association was not independent of HLA-class I polymorphisms.     

子宫内膜异位症合并不孕患者经体外受精/卵胞质内单精子注射-胚胎移植治疗后妊娠结局及相关因素的分析

目的探讨子宫内膜异位症(EMS)对不孕患者经体外受精/卵胞质内单精子注射-胚胎移植(IVF/ICSI-ET)治疗后妊娠结局的影响及其与妊娠结局相关的因素。方法选择行IVF/ICSI-ET治疗的46例EMS合并不孕患者的55个取卵周期作为EMS组;选择同期行IVF/ICSI-ET治疗的126例非EMS患者的156个周期作为对照组。回顾性分析患者的临床资料,并进一步分析与妊娠结局相关的因素。结果 EMS组CA-125水平、周期取消率显著高于对照组(P0.05);基础窦卵泡数(AFC)、hCG注射日成熟卵泡数、获卵数、MII卵数、双原核(2PN)数、卵裂数、优质胚胎数、优质胚胎率显著低于对照组(P0.05);hCG注射日成熟卵泡数与EMS患者未妊娠的相关回归系数0。结论 EMS合并不孕患者卵巢储备功能下降,卵子和胚胎质量下降,更易取消周期。但其卵子成熟率、正常受精率及临床结局与非EMS对照组不孕患者相比无统计学差异;hCG注射日成熟卵泡数是EMS患者妊娠的保护因素。     

子宫内膜异位症相关性不孕卵泡液代谢物组初筛及其与卵母细胞质量的关系

目的探讨与子宫内膜异位症(EMS)相关性不孕患者卵母细胞发育潜能相关的代谢物组。方法利用超高效液相色谱-质谱(HPLC-MS)对接受体外受精(IVF)的EMS相关性不孕患者即EMS组(n=27)和同期因男方因素行体外受精的健康妇女即对照组(n=28)进行卵泡液代谢组学分析。结果共观察到与EMS相关性不孕密切相关的差异代谢物28种,主要有脂类、核苷酸类、蛋白降解片段及其它等四大类,其中上调的代谢物主要有Valyl-Arginine、Methyl-15-cyanopentadecanoate、4-Oxo-13-cis-retinoate等15种;下调的代谢物主要有Menadiol dibutyrate、3-hydroxynonanoyl carnitine、Phytosphingosine等13种。结论本研究发现并描绘出两组卵泡液差异性代谢物谱,这28种代谢物组可能成为预测EMS妇女卵母细胞早期发育潜能的重要生物标志物。然而,并未见其与随后的胚胎质量、累积妊娠率以及活产率间明显的相关性。
