Circannual Variation in the Incidence of Uterine Cervix Cancer

The impact of uterine cervix cancer (UCC) can be greatly reduced by regular vaginal examination and other preventive measures. With this aim, UCC screening programs had been developed and applied for several years in Mexico and elsewhere. One point still to be considered in such preventive programs is the possible circannual pattern in the morbidity or mortality of UCC. With the aim of identifying a possible circannual pattern of variation in the incidence of UCC, we analyzed the monthly totals of positive detected cases of UCC in the state of Nuevo León (Mexico) between 1978 and 1987. For eliminating bias due to the seasonal variation in the number of preventive check-ups, data were first expressed in percentage of tests done in the same month. The least-squares fit of a 1 -year cosine curve to the data reveals a statistically significant circannual pattern (p = 0.013), with a maximum of relative incidence detected in February. Results indicate UCC incidence higher than the yearly average during the winter, with secondary peaks in August and November. This pattern of variation is similar if one considers separately for analysis the relative incidence of type III, IV, or V UCC (relating to cases suggesting, highly suggesting, or concluding a malignant alteration, respectively). For evaluating the cost-effectiveness of the UCC screening campaign providing these data, the monthly totals of screening check-ups done over the same period were also analyzed. Results reveal a statistically significant circannual rhythm (p > 0.001), with a maximum detected in June. This timing seems to be related to the incidence of most common diseases in Mexico, such as giardiasis and salmonellosis, but not to the UCC morbidity rates. Health educational and screening campaigns for prevention of UCC and other major conditions should be timed during the year according to morbidity and mortality statistics, for which a circannual pattern of variation is documented herein.     

Physiological and molecular determinants of embryo implantation

Embryo implantation involves the intimate interaction between an implantation-competent blastocyst and a receptive uterus, which occurs in a limited time period known as the window of implantation. Emerging evidence shows that defects originating during embryo implantation induce ripple effects with adverse consequences on later gestation events, highlighting the significance of this event for pregnancy success. Although a multitude of cellular events and molecular pathways involved in embryo–uterine crosstalk during implantation have been identified through gene expression studies and genetically engineered mouse models, a comprehensive understanding of the nature of embryo implantation is still missing. This review focuses on recent progress with particular attention to physiological and molecular determinants of blastocyst activation, uterine receptivity, blastocyst attachment and uterine decidualization. A better understanding of underlying mechanisms governing embryo implantation should generate new strategies to rectify implantation failure and improve pregnancy rates in women.     

Uterine Transplantation: Ethical Considerations within Middle Eastern Perspectives

The field of reproductive medicine witnessed a breakthrough in September 2014 with the first successful live birth post uterine transplantation. This success represents the culmination of decades' worth of research on infertility and reproductive medicine. This subject of infertility gathers special attention in the Middle East, as childbearing is given paramount importance in the family unit. And as with any new medical advancement, Middle Eastern people look to their religious authorities for guidance. This paper describes the various ethical quandaries related to uterine transplantation, from a perspective of the religious and societal factors that are unique to the Middle East, and embeds them within the conversation of its alternative solutions.     

子宫动脉化疗栓塞术治疗胎盘植入61 例的临床分析

目的:探讨子宫动脉化疗栓塞术治疗胎盘植入的临床疗效及预后。方法:以胎盘植入患者61例为研究对象,按治疗方式不同分为保守治疗组31例和化疗栓塞组30例。保守治疗组仅单纯口服米非司酮治疗,而化疗栓塞组采用子宫动脉化疗栓塞术进行治疗。比较两组患者的临床疗效、手术时间、出血量、输血量、住院时间、胎盘排出和月经复潮时间,术后并发症的发生情况,并随访术后1年患者的月经情况和妊娠情况。结果:经子宫动脉化疗栓塞术后29例成功止血,有1例未能止血而行子宫切除术。栓塞术后未出现器官局部缺血坏死、神经损伤等严重并发症,发热、下腹痛为常见并发症。而保守治疗组的31例患者中,因治疗失败导致切除子宫的7例,仅24例有效保留子宫,成功率仅77.4%,严重影响患者以后的生育能力。6例发生宫腔感染,4例发生宫腔粘连。子宫动脉化疗栓塞组β-HCG恢复正常时间、输血量、胎盘完全清除时间、月经异常的发生情况均优于保守治疗组,差异有统计学意义(P0.05)。对子宫动脉化疗栓塞术组患者进行为期1年的随访,14例患者在术后1个月后有胎盘组织自阴道排出,有11例患者2个月后发现胎盘残留,予以清宫术,除3例失访病例,其余患者在随访时间内恢复正常月经,并有2例再次妊娠者。结论:采用子宫动脉化疗栓塞术治疗胎盘植入,其术前准备时间和手术时间均短,出血控制迅速且并发症少,有助于保留患者的子宫,提高患者的生活质量。

目的:研究血立停胶囊对早孕大鼠Ru486药物流产后对子宫平滑肌收缩频率、收缩幅度及活动力变化的影响,旨在探讨血立停胶囊治疗药物流产后出血的作用机制。方法:选择妊娠Wistar大鼠,随机分为6组,即对照组,米非司酮组,大剂量血立停组,小剂量血立停组,催产素组,止血敏组。于妊娠第7天,开始相应处理,妊娠第14天分别监测以下指标后处死:在体子宫平滑肌收缩力,收缩幅度、收缩频率。结果:大剂量血立停可明显增强大鼠在体子宫平滑肌活动力、提高子宫平滑肌收缩频率、收缩幅度,与对照组比较差异有显著性(p<0.05)。结论:血立停胶囊可增强大鼠子宫平滑肌兴奋性,从而起到对药物流产后阴道出血的治疗作用。     

腹腔镜与经腹子宫肌瘤剔除术对有生育要求子宫肌瘤患者妊娠结局的影响及术后妊娠率的影响因素分析

摘要 目的：研究腹腔镜与经腹子宫肌瘤剔除术对有生育要求子宫肌瘤患者妊娠结局的影响及术后妊娠率的影响因素。方法：选取我院2018年4月至2021年4月收治的80例有生育要求的子宫肌瘤患者,其中接受经腹子宫肌瘤剔除术治疗的40例归为经腹组,接受腹腔镜子宫肌瘤剔除术治疗的40例归为腹腔镜组。比较两组手术疗效指标,术后并发症发生率以及术后妊娠率。此外,80例患者根据出院后1年是否妊娠分为妊娠组和未妊娠组,以多因素Logistic回归分析术后妊娠率的影响因素。结果：在术后失血量、肛门恢复排气时间以及住院时间方面比较,腹腔镜组均优于经腹组（P＜0.05）。腹腔镜组术后并发症发生率低于经腹组（P＜0.05）,两组术后妊娠率对比无统计学差异（P＞0.05）。单因素分析结果显示：年龄、肌瘤数目和子宫肌瘤剔除术患者术后是否妊娠有关（P＜0.05）,而孕次、肌瘤类型、肌瘤最大直径以及穿透宫腔与否和子宫肌瘤剔除术患者术后是否妊娠无关（P＞0.05）。多因素Logistic回归分析结果显示：年龄≥35岁以及肌瘤多发是子宫肌瘤剔除术患者术后未妊娠的危险因素（P＜0.05）。结论：腹腔镜与经腹子宫肌瘤剔除术对有生育要求子宫肌瘤患者妊娠结局的影响程度相当,但腹腔镜术式有助于患者术后康复,同时降低并发症发生风险。此外,年龄较大和肌瘤数目较多会使子宫肌瘤剔除术患者术后妊娠难度增加。     

不孕症患者的子宫自然杀伤细胞、浆细胞与子宫内膜异位症的相关性

摘要 目的：探究不孕症患者的子宫自然杀伤细胞、浆细胞与子宫内膜异位症的相关性。方法：选择80例患有子宫内膜异位症的不孕症患者做为本研究的不孕症组和80例正常生育的健康女性做为本研究的健康组,对比分析两组患者人口学基本资料、子宫自然杀伤细胞（uNKs）、浆细胞（PC）水平、血清性激素水平、子宫内膜中血管内皮生长因子（VEGF）表达情况、免疫细胞水平。通过Person法分析不孕症患者的子宫自然杀伤细胞、浆细胞与子宫内膜异位症的相关性。结果：两组的BMI指数、流产史、吸烟史、饮酒史比较,差异有统计学意义（P<0.05）;不孕症组患者uNKs、抗苗勒氏管激素（AMH）和黄体生成素（LH）水平均显著高于健康组;PC、卵泡刺激素（FSH）、雌激素（Estrogen）和性激素结合球蛋白（SHBG）、VEGF阳性表达水平、CD4⁺、CD8⁺和CD4⁺/CD8⁺水平均显著低于健康组,差异有统计学意义（P<0.05）。另外,不孕症患者的uNKs与子宫内膜异位症存在显著的正相关关系（r=1.555,P<0.001）;PC与子宫内膜异位症存在显著的负相关关系（r=-3.778,P<0.001）。结论：不孕症患者的uNKs、PC参与不孕症的发生和发展过程,对女性子宫内膜异位症的诊断具有重要的参考意义。     

腹腔镜下子宫血管阻断术联合子宫肌瘤剜除术治疗子宫肌瘤的回顾性研究

摘要 目的：回顾性分析子宫肌瘤剜除术联合腹腔镜下子宫血管阻断术治疗子宫肌瘤的临床疗效。方法：分析2017年6月~2019年7月期间我院收治的子宫肌瘤患者的临床资料（n=150）。根据手术方法的不同将患者分为A组（腹腔镜下子宫肌瘤剜除术治疗,73例）和B组（腹腔镜下子宫血管阻断术联合子宫肌瘤剜除术治疗,77例）,对比两组术中、内分泌激素、术后恢复指标、妊娠情况、并发症发生率及复发率。结果：两组患者手术时间对比无统计学差异（P>0.05）,B组的术中出血量少于A组,术后排气时间、住院天数、下床活动时间短于A组（P<0.05）。A组术前、术后3个月、术后6个月黄体生成素(LH) 、卵泡刺激素(FSH) 、雌二醇(E₂) 水平组内对比无统计学差异（P>0.05）。B组术前、术后3个月、术后6个月E₂水平呈降低后升高趋势,LH、FSH水平呈升高后降低趋势（P<0.05）。B组术后3个月LH、FSH水平高于A组,E2水平低于A组（P<0.05）。与A组相比,B组的并发症发生率明显下降,组间对比有差异（P<0.05）。B组的妊娠率高于A组,子宫肌瘤复发率低于A组（P<0.05）。两组流产率组间对比无统计学差异（P>0.05）。结论：与单纯子宫肌瘤剜除术相比,结合腹腔镜下子宫血管阻断术治疗子宫肌瘤患者可减少术中出血量,促进患者术后恢复,降低并发症发生率及复发率,虽然其对卵巢功能有轻微、短暂性影响,但可逐步恢复,且有利于提高妊娠率。
