本研究的目的为前瞻性评价MR扩散加权成像在区分复杂附件肿块中的作用。77例（22～87岁）复杂性附件肿块病人（30例良性,47例恶性）均于术前行包括扩散加权成像的MRi检查。除分析常规MRi表现外,还测量了b值为1000的囊性及实性部分的表观扩散系数（ADC）值。计算预测良恶性病变的阳性似然比（PRL）。预测良性最有意义的标准为实性部分在b值为1000条件下呈低信号（PRL=10．9）,T2低信号（PRL=5．7）,无实性成分（PRL=3．1）,无腹水或腹膜种植（PRL=2-3）和无乳头状突起（PRL=2．3）。

摘要目的回顾性评价MRi鉴别子宫肌层良性与恶性肿瘤的能力。方法 51例女性在手术前行MRi检查以评价子宫肌层单发的肿瘤。组织病理学证实其中25例为不确定或恶性间质性肿瘤,26例为良性平滑肌瘤。除常规MRi形态学标准以外还记录b1 000信号强度及其表观扩散系数(ADC)。并将各数据转化为优势比(OR)作为统一标准。一个多变量分析,构建成一个解释模型。结果提示子宫恶性肿瘤的标准是b1 000信号呈高强度(OR=+∞),T2Wi呈等信号(OR=+∞),

Arctic sea-ice extent reaches its minimum each year in September. On 11 September 2023 the minimum was 4.969 million square kilometers(***^(2)). This was not a record low, which occurred in 2012, when the minimum was 4.175 ***^(2), 0.794 ***^(2) less than the minimum in 2023. However, the ice extent had decreased by 0.432 ***^(2) compared with 2022. Nevertheless, the summer melting in 2023 was remarkably less than expected when considering the strong heat waves in the atmosphere and ocean, with record temperatures set around the world. in general, there is a high correlation between the long-term decrease in sea-ice extent and the increasing CO_(2) in the atmosphere, where the increase of CO_(2) in recent decades explains about 80% of the decrease in sea ice in September, while the remainder is caused by natural variability.

A case of septic expulsion of a leiomyoma is reported 18 weeks after uterine artery embolisation (UAE). The patient underwent UAE for a symptomatic sub- mucous leiomyoma (type 2) of 5 cm. She was feverish and presented pelvic pain and purulent vaginal discharges. Vaginal examination revealed a necrotic mass prolapsed through the cervix that was carefully twisted out. Histopathologic examination showed extensive necrosis of the myomatous tissue. Microbiologic cultures showed heavy growth of Escherichia coli. Such findings challenge the interest and the safety of UAE for submucous fibroids. Our case report stresses that uterine artery embolisation for submucous fibroids does not constitute, because of its risks, an alternative to conventional surgical treatment represented mainly by hysteroscopic resection.
