Objective To analyze the effect of surgical position nursing for radiofrequency ablation in posterior root ganglion in lumbar spinal nerve guided by MRI in lateral prone position．Methods Sixty-two patients with lumbar disc herniation hospitalized in Liwan Central Hospital of Guangzhou from September 2018 to December 2020 were randomly divided into two groups（the lateral prone position group and the prone position group,31 patients in each group）．The lateral prone position group used the lateral prone position with about 30 degrees elevation of the affected side,and the prone position group used the standard prone position for operation．Operating time,surgical complications,surgical position related complications,and operator satisfaction evaluation of surgical field exposure were recorded in both groups．Results All patients completed the operation successfully．No surgical complications such as bleeding,infection,lower limb paralysis,aggravated nerve injury or organ injury were found in the two groups．No surgical position related complications such as intraocular pressure raising,brachial plexus injury or pressure ulcers in both the groups either．The operation time was（60.65±12.45）min in the lateral prone position group and（70.58±10.25）min in the standard prone position group,respectively,and the difference was statistically significant（t=3.429,P=0.001）．The surgeon’s satisfaction evaluation of the surgical field exposure was much higher in the lateral prone position group（93.55%）compared with the standard prone position group（77.42%）,and the difference was statistically significant（χ²=4.29,P=0.038）．Conclusions Radiofrequency ablation in posterior root ganglion of lumbar spinal nerve guided by MRI in lateral prone position is safe and effective．Good surgical position nursing can effectively prevent complications．

目的 探讨振幅整合脑电图（aEEG）联合头颅磁共振成像（cMRI）对早产儿矫正12月龄时神经发育的预测价值。方法 选取110例早产儿为研究对象,并在矫正12月龄时采用Gesell 发育量表评估发育商（DQ）,依据DQ分为Gesell 正常组（DQ≥85,n=83）、Gesell 异常组（DQ<85,n=27）。采集早产儿及母亲临床资料,对比两组出生后72 h内aEEG、矫正胎龄37周时cMRI检查指标差异。结果 两组早产儿及母亲基线资料比较差异无统计学意义（P>0.05）。相较于Gesell 正常组,Gesell 异常组双顶径（BPW）降低[（70.68±5.32）mm vs（66.54±3.69）mm],睡眠-觉醒周期（SWC）不成熟率（20.48% vs 85.19%）、aEEG异常率（30.12% vs 70.37%）、两半球间距（IHD）增高[（2.95±0.83） mm vs（3.56±0.72）mm]（P<0.05）。Pearson相关分析结果显示,DQ值与IHD呈负相关,DQ值与BPW呈正相关（r=-0.361、0.598,P<0.05）。二元Logistic回归分析结果显示,BPW增高是Gesell 异常的独立保护因素（P<0.05）,IHD增高、SWC不成熟及aEEG异常是Gesell 异常的独立危险因素（P<0.05）。结论 早产儿出生后72 h内aEEG异常、矫正胎龄37周时cMRI异常可能提示矫正12月龄时不良神经发育结局。

Objective To evaluate the predictive value of amplitude-integrated electroencephalogram combined with cranial magnetic resonance on neurodevelopment for preterm infants at corrected age of 12 months．Methods A total of 110 preterm infants were selected as study subjects,and Gesell developmental scale was used to evaluate developmental quotient（DQ）at corrected age of 12 months．According to DQ,they were divided into normal Gesell group（DQ≥85,n=83）and abnormal Gesell group（DQ<85,n=27）．Clinical data of preterm infants and their mothers were collected,and the differences of amplitude-integrated electroencephalogram and cranial MRI（cMRI）were compared between two groups．Results There was no significant difference in baseline data between two groups（P>0.05）．Compared with the normal Gesell group,the biparirtal width（BPW）in the abnormal Gesell group was decreased（70.68±5.32mm vs 66.54±3.69mm）,the immaturity rate of sleep-wake cycle（SWC）（20.48% vs 85.19%）,the abnormal rate of aEEG（30.12% vs 70.37%）,and（IHD）（2.95±0.83mm vs 3.56±0.72mm）were increased（P<0.05）．The results of Pearson correlation analysis showed that DQ was negatively correlated with IHD,and DQ was positively correlated with BPW（r=-0.361、0.598,P<0.05）．Binary Logistic regression analysis showed that increased BPW was an independent protective factor for abnormal Gesell（P<0.05）,and increased IHD,immature SWC and abnormal aEEG were independent risk factors for abnormal Gesell（P<0.05）．Conclusions Abnormal aEEG within 72h after birth and abnormal cMRI at corrected age of 37 weeks may lead to adverse neurodevelopmental outcomes at corrected age of 12 months．

胶质瘤是颅内最常见的原发性恶性肿瘤,其分级对患者治疗方式的选择和预后至关重要。尽管目前组织病理学仍是其最为可靠的分级手段,但需通过有创性手术以获取组织样本,存在一定的风险。相较之下,磁共振成像（MRI）作为一种非侵入性影像诊断工具,在胶质瘤分级中发挥着不可或缺的作用。然而,传统MRI评估受限于医师个体主观性强和可重复性差的问题,一定程度上影响了准确的分级结果。近年来,影像组学技术的崭露头角为解决上述难题开辟了新视角,通过高通量提取影像数据特征捕捉并量化肿瘤的影像学表现,避免因主观因素而导致的不确定性,协助医师更准确地评估肿瘤的恶性程度。本文对近五年来MRI影像组学在胶质瘤术前分级预测方面的相关研究进行了简要综述,旨在为相关领域研究者提供有益的参考和借鉴,以推动MRI影像组学在临床实践中的应用。

Glioma is the most common primary malignant brain tumor,and its grading is crucial for treatment decisions and prognosis．Currently,histopathology remains the gold standard for grading,but it requires invasive procedures and carries inherent risks．In contrast,magnetic resonance imaging（MRI）,a non-invasive diagnostic tool,plays an indispensable role in glioma grading．However,traditional MRI assessment is hampered by interobserver subjectivity and limited repeatability,which compromise grading accuracy．In recent years,radiomics,a burgeoning field,has offered a promising solution to address these challenges．By extracting high-dimensional imaging data features,radiomics enables the quantification of tumor radiological characteristics and elimination of subjectivity-related discrepancies．This technology assists clinicians in more precisely assessing the malignancy of gliomas．This article summarizes relevant studies in the past five years on the application of MRI radiomics in preoperative glioma grading,aiming to provide valuable insights and guidance to researchers in the field and promote the clinician implementation of MRI radiomics．

Objective To investigate the predictive value of multi-parameter quantitative features of dynamic contrast-enhanced magnetic resonance imaging（DCE-MRI）in the risk of axillary lymph node metastasis（ALNM）in breast cancer．Methods Clinical data of 155 patients with breast cancer diagnosed by surgery and pathology in Foshan Gaoming District People's hospital from March 2020 to November 2022 were retrospectively collected．According to whether the patients had ALNM,they were divided into ALNM group（n=39）and non-ALNM group（n=116）．Univariate analysis and multiple Logistic regression models were used to explore the influencing factors of ALNM in breast cancer．Results There was no significant difference in mass texture,mass diameter,mass location,mass shape and internal enhancement between the ALNM group and the non-ALNM group（t/χ²=2.249,0.977,1.369,0.524,2.158,P>0.05）．There were significant differences in ADC value,ALN short diameter,tumor margin and TIC curve between the two groups（t/χ²=6.573,9.873,29.441,2.031,P<0.05）．Binary Logistic regression model showed that ADC value,ALN short diameter（≥5 mm）and tumor margin（blur）were risk factors for the occurrence of breast cancer ALNM（OR=0.251,0.106,0.002,P<0.05）．Conclusions Among the multi-parameter quantitative features of DCE-MRI,the ADC value of breast cancer,the short diameter of ALN（≥5 mm）,and the edge of the tumor（blur）are the risk factors for the occurrence of ALNM in breast cancer．

乳腺癌是女性最常见的原发恶性肿瘤之一。目前,通过采用综合治疗手段,包括手术、新辅助治疗、辅助放化疗等多种手段,乳腺癌已成为疗效最佳的实体肿瘤之一。其中,新辅助治疗（NAT）包括新辅助化疗、靶向治疗和内分泌治疗,目的是使肿瘤降期、保乳、保腋窝,并可观察药物敏感性,是当前乳腺癌综合治疗中非常重要的组成部分,其治疗疗效对患者手术方式的选择和预后至关重要。尽管病理学评价在评估NAT疗效方面被公认为金标准,但其局限性在于只能通过有创手段在治疗后进行,无法在治疗前对患者做出准确预测。磁共振成像（MRI）作为一项广泛使用的乳腺成像技术,在评估NAT疗效中扮演着关键角色。近年来,人工智能技术,尤其是影像组学（Radiomics）和深度学习（Deep Learning）,在医学影像分析领域取得了显著进展。这些技术能够从医学图像中提取大量肉眼难以识别的特征,揭示病变内部的微观结构和生物学行为,全面反映肿瘤的异质性,这不仅有助于临床医生更准确地区分良、恶性肿瘤,还能对恶性肿瘤的预后进行更为精确的评估。本文系统综述了近年来基于MRI的人工智能技术在乳腺癌新辅助治疗疗效评估中的应用研究,旨在促进人工智能在NAT临床实践中的应用和发展,为乳腺癌NAT治疗策略的优化和个性化医疗的实现提供科学依据。

Breast cancer is one of the most common primary malignant tumors in women．Currently,breast cancer has become one of the most effective solid tumors by using comprehensive treatment methods,including surgery,neoadjuvant therapy,adjuvant radiotherapy and chemotherapy．Among them,neoadjuvant therapy（NAT）,including neoadjuvant chemotherapy,targeted therapy and endocrine therapy,is a very important part of the current comprehensive treatment of breast cancer．It aims to reduce the tumor stage,preserve the breast,preserve the armpit,and observe the drug sensitivity．Its therapeutic effect is crucial to the choice of surgical methods and prognosis of patients．Although pathological evaluation is recognized as the gold standard in evaluating the response to NAT,its limitation is that it can only be performed after treatment by invasive means,and cannot accurately predict response before treatment．As a widely used breast imaging technology,magnetic resonance imaging（MRI）plays a key role in evaluating the response to NAT．However,traditional MRI evaluation methods are limited by the individual differences of interobserver and the low repeatability of evaluation results,which affects the accuracy of efficacy evaluation to a certain extent．In recent years,artificial intelligence technology,especially radiomics and deep learning,has made significant progress in the field of medical image analysis．These techniques can extract a large number of features that are difficult to be recognized by the naked eye from medical images,reveal the internal microstructure and biological behavior of the lesion,and fully reflect the heterogeneity of the tumor．This not only helps clinicians to distinguish benign and malignant tumors more accurately,but also makes a more accurate assessment of the prognosis of malignant tumors．This article reviews the application and progress of MRI-based artificial intelligence technology in evaluating the response to neoadjuvant therapy for breast cancer in the past five years,aiming to promote the application and development of artificial intelligence in NAT clinical practice,and provide a scientific basis for the optimization of NAT treatment strategy and the realization of personalized medicine for breast cancer．
