叶酸代谢关键限速酶亚甲基四氢叶酸还原酶基因多态性与宫颈癌的关系

宫颈癌是影响女性生活健康最常见的生殖系统恶性肿瘤之一,其发生、发展与多种因素相关,除环境危险因素(如人乳头瘤病毒感染、多个性伴侣、不良生活习惯等)外,遗传易患因素也发挥着至关重要的作用。叶酸水平及其代谢关键酶亚甲基四氢叶酸还原酶(MTHFR)基因多态性与宫颈癌关系密切,叶酸水平的改变、MTHFR基因多态性可通过影响体内多种甲基化过程,从而改变不同个体的癌易患性,导致肿瘤的发生。然而,这种改变存在种族、地域等差异,且受多种环境因素及其他代谢途径的影响,目前尚无定论。     

13例新生儿红斑狼疮的临床特征、皮损后遗表现

【摘要】 目的 探讨新生儿红斑狼疮（NLE）的皮损后遗表现，分析可能的相关因素。方法 回顾2016—2020年首都儿科研究所附属儿童医院皮肤科收集并长期随访的13例NLE，分析患儿及母亲临床特征、患儿皮损后遗表现。结果 13例皮损发病时间为出生后0 ~ 120 d，平均15 d，随访时间15 ~ 43个月，皮损形态主要为环状红斑、斑丘疹、鳞屑，皮损消退时间2 ~ 18个月（平均7.4个月）。6例皮损消退后出现色素异常表现，3例同时出现色素减退和色素沉着，2例仅有色素减退，1例仅有色素沉着，1例色素减退患儿在随访18个月后色素减退复色，未见毛细血管扩张以及萎缩或瘢痕。8例患儿母亲孕前无异常，4例患儿母亲抗ANA、抗SSA/Ro、抗SSB/La抗体均阳性。结论 NLE的皮肤受累可出现后遗皮肤表现，常见为色素异常，多数长期未消退，应注意患儿母亲可能存在的潜在性免疫系统异常。     

单中心559例卵巢癌患者淋巴结转移的危险因素分析与淋巴结切除术临床决策探讨#br#

【Abstract】?Objective?To review the data of patients with ovarian cancer, analyze the related factors of pelvic lymph node metastasis (PLNM) and para-aortic lymph node metastasis (PALNM), and establish a predictive model, so as to provide suggestions for clinical practice. Methods?The clinicopathological data of 559 patients with ovarian cancer treated in Chinese PLA General Hospital from January 2014 to January 2019 were retrospectively analyzed. The risk factors affecting PLNM and PALNM were analyzed by univariate and logistic regression, and the prediction model was established. Results?Among 559 ovarian cancer patients, pelvic lymph node metastasis was found in 205 cases (36.67%) and abdominal para-aortic lymph node metastasis in 117 cases (20.93%). The independent risk factors affecting PLNM were bilateral lesions (OR=2.278, 95%CI: 1.433~3.621), pelvic metastases (OR=1.801, 95%CI: 1.154~2.810), and abdominal metastases (OR=4.177, 95%CI: 2.597~6.717) and appendiceal metastasis (OR=2.332, 95%CI: 1.389~3.915); The independent risk factors affecting PALNM were appendiceal metastasis (OR=2.324, 95%CI: 1.383~3.906) and PLNM (OR=7.629, 95%CI: 4.615~12.610). Age (≥55 years) (OR=0.566, 95%CI: 0.350~0.915) was the protective factor. The ROC curve AUC of PLNM and PALNM was 0.803 (95%CI: 0.767~0.840) and 0.793 (95%CI: 0.745~0.841), respectively. Conclusion?Bilateral lesions, pelvic metastases, intraperitoneal metastases and appendiceal metastases were independent risk factors for PLNM in ovarian cancer patients. Appendiceal metastasis and PLNM were independent risk factors for PALNM, and age (≥55 years) was the protective factor.     

人类白细胞抗原-G与移植免疫

人类白细胞抗原-G(human leucocyte antigen G,HLA-G)属于非经典的主要组织相容性复合物Ⅰ类分子(major histocompatibility complex,MHC-Ⅰ),在妊娠期作为免疫耐受分子表达于胎盘滋养层细胞,促进母胎免疫耐受.近年来研究表明HLA-G在移植免疫中发挥重要作用,HLA-G通过多种途径参与免疫调控,诱导移植免疫耐受.笔者就HLA-G抑制移植免疫排斥的机制、功能及临床意义做一综述.     

机器人荧光显影深部浸润型子宫内膜异位症手术一例并文献回顾

目的探讨吲哚菁绿荧光显影技术在机器人深部浸润型子宫内膜异位症手术中指导手术范围的可行性。 方法选取解放军总医院第一医学中心妇产科的深部浸润型子宫内膜异位患者1例,术前完善检查,无手术禁忌,拟行机器人全子宫双附件切除＋子宫内膜异位病灶切除术。术中利用吲哚菁绿荧光显影技术指示子宫内膜异位病灶进而对病灶进行切除。 结果病变定位准确,患者术后顺利出院。 结论机器人荧光显影技术能够清晰识别子宫内膜异位病灶。这项技术简单、快速,且能够在术中实现实时定位,指导手术范围。
