盆腔器官脱垂(pelvic organ prolapse,POP)和压力性尿失禁(stress urinary incontinence,SUI)是严重影响女性生活质量的盆底功能障碍性疾病。我国流行病学资料显示,成年女性中有9.6%患有症状性POP[1],绝经后患病比例则上升到14.8%[2];SUI的患病率高达18.9%[3]。20%的女性一生中可能需要接受手术治疗POP或SUI[4]。盆底重建手术术中使用植入物(网片/吊带)的术式主要包括治疗盆腔器官脱垂的骶骨固定术(sacrocolpopexy,SC)、经阴道植入网片手术(transvaginal mesh,TVM)和尿道中段悬吊术(midurethral sling,MUS)三大类。

网片感染是盆底重建手术术后较为罕见的并发症,起病隐匿,常合并网片暴露、侵蚀或器官穿孔。其发生与网片的材质、网片与机体的相互作用、阴道细菌菌落定植以及术者的操作有关。一旦出现蜂窝织炎、脓肿、窦道/瘘管形成,处理困难,需要全面评估,首选盆腔磁共振成像(MRI)检查,并进行积极的手术处理和多学科诊疗团队支持。文章介绍了盆底重建手术术后网片感染的发病率、病因、临床表现、诊断与处理方法。选择合适的网片和术式、避免术中损伤、确切止血、应用抗生素以及尽可能避免子宫切除是较为有效的预防措施。

针对烟草领域中问句意图识别存在的特征稀疏、术语繁多和捕捉文本内部的语义关联困难等问题,提出了一种基于SBERT-Attention-LDA(Sentence-bidirectional encoder representational from transformers-Attention mechanism-Latent dirichlet allocation)与ML-LSTM(Multi layers-Long short term memory)特征融合的问句意图识别方法。该方法首先基于SBERT预训练模型和Attention机制对烟草问句进行动态编码,转换为富含语义信息的特征向量,同时利用LDA模型建模出问句的主题向量,捕捉问句中的主题信息;然后通过更改后的模型级特征融合方法ML-LSTM获得具有更为完整、准确问句语义的联合特征表示;再使用3通道的卷积神经网络(Convolutional neural network,CNN)提取问句混合语义表示中隐藏特征,输入到全连接层和Softmax函数中实现对问句意图的分类。基于烟草行业权威网站上获取的数据集开展了实验验证,实验结果表明,所提方法相比其他几种深度学习结合注意力机制的方法精确率、召回率和F1值上有显著提升,与BERT和ERNIE(Enhanced representation through knowledge integration and embedding)-CNN模型相比提升明显,F1值分别提升2.07、2.88个百分点。

We report a new high-sensitivity HⅠmapping observation of the NGC 5055 galaxy group over an area of 1°.5×0°.75 with the Five-hundred-meter Aperture Spherical radio Telescope(FAST).Our observation reveals that the warped HⅠdisk of NGC 5055 is more extended than what was previously observed by WSRT,out to239(61.7 kpc).The total HⅠmass of NGC 5055 is determined to be~1.1×10^(10)M_Θ.We identified three HⅠclouds with HⅠmasses of the order of~10^(7)M_Θat the southeastern edge of the HⅠdisk,as well as a candidate high-velocity cloud with an HⅠmass of(1.2±0.5)×10^(6)M_Θto the north of NGC *** HⅠcontent of UGCA337 is robustly detected for the first time by the FAST *** has a narrow HⅠlinewidth of W_(50)=17.4±3.8 km s^(-1)with a total HⅠmass of(3.5±0.3)×10^(6)M_Θ.Comparing the gas content and g-r color of UGCA 337 with typical low-mass dwarf galaxies,UGCA 337 appears relatively gas-poor despite its blue *** suggests that UGCA 337 may have undergone gas stripping in the *** also analyzed the possible origin of the diffuse HⅠclouds located at the outskirts of NGC 5055,and speculate that they might be the remnant features of a merger event in the past.
