为精准识别台区的线损异常,保证配电网经济、稳定运行,针对台区线损的异常情况,提出一种基于二阶聚类和鲁棒性随机分割森林(robust random cut forest,RRCF)算法的台区线损异常检测方法。首先,运用二阶聚类将台区不同的运行工况进行聚类,将相同工况的线损节点归并,然后将各类工况的节点线损数据导入RRCF算法中分析,通过删除和插入样本节点,并对插入节点后评判模型的复杂度进行计算,得到线损异常节点的评分值,进一步找出线损异常的节点。最终,通过有关实例验证所提方法的准确性与有效性。

背景:糖皮质激素有减轻炎症反应、缓解术后疼痛等作用,但对于将糖皮质激素加入鸡尾酒中注射对全膝关节置换术(TKA)相关临床疗效的研究较少。目的:评估接受含糖皮质激素的鸡尾酒注射对TKA患者的术后疼痛和皮温的影响和安全性。方法:选取2016年9月至2017年9月在我院接受单侧TKA的膝骨关节炎患者80例,年龄54~83岁,平均(66.9±10.6)岁,随机术中给予含或不含糖皮质激素的鸡尾酒注射治疗。研究组使用含有4 ml复方倍他米松配方的鸡尾酒注射。对照组接受含有等量生理盐水的鸡尾酒注射。术后记录疼痛、皮温、炎症因子变化和相关并发症。结果:术后1~3 d内研究组疼痛评分低于对照组,两组间差异在术后第2天最大(静息状态下:2.9±1.5 vs 3.6±1.7;活动状态下:3.8±1.7 vs 4.5±2.0;P<0.05),1周后两组疼痛水平逐渐相同。研究组术后切口周围皮温低于对照组,两组差异以术后第3天最明显(34.0℃±0.9℃vs 34.6℃±1.0℃,P<0.05)。研究组术后6 d内C反应蛋白、白细胞介素6水平低于对照组(P<0.05)。随访期内未见切口感染、假体周围感染等并发症。结论:含有糖皮质激素的鸡尾酒注射术后可提供额外的镇痛、抑制炎症反应作用,并加速皮温下降,有利于患者术后康复,且未增加围手术期并发症的发生。

This study addresses the problem of two-stage scheduling on batch and single machines with limited waiting time constraint; thus, the makespan is minimized.A mixed-integer linear programming model is proposed for this problem. Three tight lower bounds and a heuristic algorithm are developed. The worst-case performance of the proposed algorithm is discussed. A hybrid differential evolution algorithm is also developed to improve the solution quantity. Numerical results show that the hybrid algorithm is capable of obtaining high-quality solutions and exhibits a competitive

Cancer is a major threat to human health and causes death *** on the role of radiotherapy(RT)in the treatment of cancer is progressing;however,RT not only causes fatal DNA damage to tumor cells,but also affects the interactions between tumor cells and different components of the tumor microenvironment(TME),including immune cells,fibroblasts,macrophages,extracellular matrix,and some soluble *** cancer cells can survive radiation and have shown strong resistance to radiation through interaction with the ***,the complex relationships between the tumor cells and cellular components that play major roles in various TMEs are poorly *** review explores the relationship between RT and cell-cell communication in the TME from the perspective of immunity and hypoxia and aims to identify new RT biomarkers and treatment methods in lung cancer to improve the current status of unstable RT effect and provide a theoretical basis for further lung cancer RT sensitization research in the future.

该试验旨在揭示张掖肉牛体尺性状、胴体性状和肉质性状三组性状间的相互关系。采用简单相关分析法和典型相关分析法对三组性状24个变量进行分析。简单相关分析的结果表明:宰前重、胴体重、净肉重分别与体高、十字部高、体斜长、胸围、腹围、管围呈极显著正相关关系(P<0.05)。眼肌面积与胸围、屠宰率呈极显著正相关关系(P<0.01),与肉骨比、胴体产肉率、肌肉颜色、系水力呈极显著负相关关系(P<0.01)。典型相关分析的结果表明:体尺性状与胴体性状的第一典型相关系数达显著相关水平(P<0.05);体尺性状与肉质性状的第一典型相关系数达到极显著相关水平(P<0.01);胴体性状与肉质性状的第一典型相关系数达到极显著相关水平(P<0.01)。体尺性状与胴体性状的第1对典型变量的相关是由管围(X_(6))与胴体重(Y_(2))的相关引起的,第2对典型变量的相关主要由管围(X_(6))和净肉重(Y_(4))引起的。体尺性状与肉质性状的第1对典型变量的相关是由体高(X_(1))与剪切力(Z_(3))的相关引起的,第2对典型变量的相关主要由管围(X_(6))和粗蛋白质(Z_(7))引起的胴体性状与肉质性状第1对典型变量的相关是由胴体产肉率(Y_(8))与蒸煮损失(Z_(10))的相关引起的,第2对典型变量的相关主要由净肉重(Y_(4))和眼肌面积(Z_(6))引起的。可见,体尺性状可以较好地预测部分胴体性状和肉质性状,加速肉牛新品种培育进程。

A phase Ⅰ/Ⅱ clinical trial for treating malignant melanoma by boron neutron capture therapy（BNCT） was designed to evaluate whether the world＇s first in-hospital neutron irradiator（IHNI） was qualified for BNCT. In this clinical trial planning to enroll 30 patients, the first case was treated on August 19, 2014. We present the protocol of this clinical trial, the treating procedure, and the clinical outcome of this first case. Only grade 2 acute radiation injury was observed during the first four weeks after BNCT and the injury healed after treatment. No late radiation injury was found during the 24-month follow-up. Based on positron emission tomography-computed tomography（PET/CT） scan, pathological analysis and gross examination, the patient showed a complete response to BNCT,indicating that BNCT is a potent therapy against malignant melanoma and IHNI has the potential to enable the delivery of BNCT in hospitals.
