LEEP术对绝经后妇女高级别宫颈上皮内瘤变的诊治

目的:探讨绝经后妇女高级别宫颈上皮内瘤变行宫颈环形电切术(LEEP)诊治的临床价值。方法:选择2017年2月-2018年12月于北京妇产医院妇科微创中心因宫颈高级别鳞状上皮内病变(HSIL)行LEEP术的患者共142例,其中绝经组40例,未绝经组102例。收集2组患者的液基薄层细胞学检查(TCT)、高危型人乳头瘤病毒(HPV)检测、阴道镜检查及其活检病理结果、LEEP术后病理结果、切缘病变情况,并将上述检查结果进行组间比较。结果:2组患者阴道镜下宫颈转化区类型比较,差异有统计学意义(χ~2=28.658,P=0.000)。绝经组阴道镜活检与LEEP术后病理符合率为50.00%(20/40),未绝经组符合率为51.96%(53/102),2组差异无统计学意义(χ~2=0.044,P=0.854)。绝经组1例LEEP术后病理升级为宫颈癌,未绝经组1例LEEP术后病理升级为原位腺癌。绝经组术后病理切缘阳性8例(20.00%),未绝经组术后病理切缘阳性16例(15.69%),2组比较差异无统计学意义(χ~2=0.381,P=0.537)。2组患者术后TCT检查比较及高危型HPV感染情况比较,差异均无统计学意义(均P>0.05)。结论:LEEP手术适用于宫颈无明显萎缩的绝经后妇女高级别宫颈上皮内瘤变的诊治,以避免对宫颈病变的漏诊和过度治疗。     

Effect of Race and Ethnicity on Risk of Radiotherapy Toxicity and Implications for Radiogenomics

AimsPatient factors affect the risk of radiotherapy toxicity, but many are poorly defined. Studies have shown that race affects cancer incidence, survival, drug response, molecular pathways and epigenetics. Effects on radiosensitivity and radiotherapy toxicity are not well studied. The aim of the present study was to identify the effects of race and ethnicity on the risk of radiotherapy toxicity.Materials and methodsA systematic review was carried out of PubMed, Ovid Medline and Ovid Embase with no year limit. PRISMA 2020 guidelines were followed. Two independent assessors reviewed papers.ResultsOf 607 papers screened, 46 fulfilled the inclusion criteria. Papers were published between 1996 and 2021 and involved 30–28,354 individuals (median 433). Most involved patients with prostate (33%), breast (26%) and lung (9%) cancer. Both early and late toxicities were studied. Some studies reported a higher risk of toxicity in White men with prostate cancer compared with other races and ethnicities. For breast cancer patients, some reported an increased risk of toxicity in White women compared with other race and ethnic groups. In general, it was difficult to draw conclusions due to insufficient reporting and analysis of race and ethnicity in published literature.ConclusionsReporting of race and ethnicity in radiotherapy studies must be harmonised and improved and frameworks are needed to improve the quality of reporting. Further research is needed to understand how ancestral heritage might affect radiosensitivity and risk of radiotherapy toxicity.     

中国经肛全直肠系膜切除结构化培训尸体手术训练中学员表现分析

目的 分析参加经肛全直肠系膜切除（taTME）结构化培训尸体手术训练中学员表现。方法 针对2018年4月至2019年7月参加taTME结构化培训研讨会的学员，通过问卷调查获取数据，分析学员在尸体手术训练过程中各步骤的技术表现、术中困难及并发症以及术后标本直肠系膜完整度等结果。结果 共45名学员参加taTME结构化培训研讨会，其中39名学员返回问卷。荷包缝合方面，5名（12.8%）学员未能独立完成，7名（17.9%）学员需要经过两次或以上尝试来完成荷包缝合。在各方向直肠系膜间隙的切开分离过程中，85%～90%学员能在教员不同程度上的口头指导下亲自完成。最终标本直肠系膜完整性的评价中，系膜不完整的标本共5例（12.8%），系膜近乎完整的标本共18例（46.2%），系膜完整的标本共16例（41.0%）。术中并发症及遇到困难方面，18名（46.2%）学员进入错误间隙，1名（2.6%）学员出现直肠穿孔，4名（10.3%）学员出现荷包失败，2名（5.1%）学员出现尿道损伤。单因素分析发现只有学员培训前独立完成taTME手术的例数≥1例为术中不出现并发症的影响因素。结论 参加培训的学员在荷包缝合、直肠全层切开以及直肠系膜间隙的分离等各重要手术步骤中获得较为充足的亲自上手练习机会，较丰富的工作经验以及腹腔镜全直肠系膜切除术（TME），经肛门内镜微创手术（TEM）、经肛门微创手术（TAMIS）的手术经验并不能降低taTME手术经肛操作部分的术中并发症发生率。参加包含尸体手术训练的taTME结构化培训有助于降低术中并发症发生率并提高手术安全性。     

原发性肝癌患者手术切除术后早期复发影响因素分析

目的:探究原发性肝癌患者手术切除术后早期复发影响因素分析。方法:对广州市番禺区中医院2017年2月-2019年2月收治的原发性肝癌患者98例进行回顾性分析,依据各项临床指标分析手术切除术后早期复发的影响因素。结果:原发性肝癌患者经由手术切除后出现复发的可能性较高,同时手术切缘有残留、包膜不完整、肿瘤结节、心理因素、甲胎蛋白、血管侵犯、肝硬化及肿瘤直径等均是影响原发性肝癌手术期后再复发的高危因素。结论:原发性肝癌通常具有术后复发的生物学特性,依据对手术切除术之后早期复发因素的分析,对手术风险与治疗方案进行充分评估,同时要求患者进行定期复查及随访等工作,可对患者手术成功以及并发症的防治等均具有积极意义。     

从TaTME发展看直肠癌微创外科治疗进步

随着科学技术的进步和对疾病本身认识的深入，直肠癌的外科治疗从局部切除到全直肠系膜切除（TME），从开放手术到腹腔镜手术，再从腹腔镜手术到机器人手术，目前已经进入微创时代。在此时代背景下，经肛门全直肠系膜切除（TaTME） 应运而生。正如TME的提出者Heald所言：“TaTME是近30年直肠癌外科治疗技术的集大成者”，其发展的每一个阶段都有很强的代表性，已成为直肠癌微创外科治疗技术进步发展的一个缩影。     

A genome wide association study identifies new genes potentially associated with eyelid sagging

Sagging eyelid is considered as an outward of skin ageing and may cause medical issues. However, little is known about the factors involved in sagging eyelid. The study, which aims at determining genetic risk factors for eyelid sagging, was conducted in a cohort of 502 unrelated Caucasian women living in the Paris region. All included participants were aged between 44 and 70 years old (mean age, 57.6 years old). The severity of sagging eyelid was graded in 6 categories by a dermatologist using standardized photographs of the face. A genome wide association study adjusted on potential risk factors (including age and smoking habits) was conducted to identify genetic associations. Two single nucleotide polymorphisms in total linkage disequilibrium on chromosome 10, rs16927253 (P = 7.07 × 10^‐10) and rs4746957 (P = 1.06 × 10^‐8), were significantly associated with eyelid sagging severity. The rs16927253‐T and rs4746957‐A alleles showed a dominant protective effect towards eyelid sagging. These polymorphisms are located in intronic parts of the H2AFY2 gene which encodes a member of the H2A histone family and very close to the AIFM2 gene that induces apoptosis. Additionally, single nucleotide polymorphisms with a false discovery rate below 0.25 were located nearby the type XIII collagen COL13A1 gene on chromosome 10 and in the ADAMTS18 gene on chromosome 16. Several relevant genes were identified by the genome wide association study for their potential role in the sagging eyelid severity.
