Aiming at the problem that existing models in aspect-level sentiment analysis cannot fully and effectively utilize sentence semantic and syntactic structure information, this paper proposes a graph neural network-based aspect-level sentiment classification model. Self-attention, aspectual word multi-head attention and dependent syntactic relations are fused and the node representations are enhanced with graph convolutional networks to enable the model to fully learn the global semantic and syntactic structural information of sentences. Experimental results show that the model performs well on three public benchmark datasets Rest14, Lap14, and Twitter, improving the accuracy of sentiment classification.

Background Self-reflectiveness,one dimension of cognitive insight,plays a protective role in an individual’s mental state.Both high and low levels of self-reflectiveness have been reported in patients with schizophrenia and individuals at clinical high risk for the illness.Aims This study aimed to explore the relationship patterns between self-reflectiveness and clinical symptoms in individuals during the pre-morbid and early clinical stages of psychosis.Methods A total of 181 subjects,including individuals with attenuated positive symptoms(APS,n=122)and patients with first-episode psychosis(FEP,n=59),completed the Beck Cognitive Insight Scale and were evaluated using the Schedule of Assessment of Insight and Positive and Negative Syndrome Scale.All subjects were classified into three groups according to their level of selfreflectiveness:low level(LSR,n=59),medium level(MSR,n=67)and high level(HSR,n=55).Both linear and nonlinear relationships between self-reflectiveness and clinical symptoms were explored.Results More individuals with APS were classified into the MSR group,while more patients with FEP were classified into the LSR group.The LSR group demonstrated less awareness of illness than the MSR and HSR groups,more stereotyped thinking and poorer impulse control but less anxiety than the MSR group,and lower levels of blunted affect and guilt feelings than the HSR group.The MSR group demonstrated lower stereotyped thinking than the HSR group.Compared to the LSR group,the MSR group had increased selfreflectiveness,improved awareness of illness,decreased stereotyped thinking,and better impulse control,but increased feelings of guilt.The HSR group showed increased stereotyped thinking when compared to the MSR group,but the other variables did not change significantly between these two groups.Overall,self-reflectiveness demonstrated an approximately inverse S-shaped relationship with the awareness of illness,a U-shaped relationship with stereotyped thinking and poor impulse control,and an almost linear relationsh

Background Neural oscillations directly reflect the rhythmic changes of brain activities during the resting state or while performing specific tasks.Abnormal neural oscillations have been discovered in patients with schizophrenia.However,there is limited evidence available on abnormal spontaneous neural oscillations in clinical high risk for psychosis(CHR-P).The brain signals recorded by the magnetoencephalography(MEG)technique are not to be disrupted by the skull and scalp.Methods In this study,we applied the MEG technique to record the resting-state neural activities in CHR-P.This was followed by a detailed MEG analysis method including three steps:(1)preprocessing,which was band-pass filtering based on the 0.5-60Hz frequency range,removal of 50Hz power frequency interference,and removal of electrocardiography(ECG)and electrooculography(EOG)artefacts by independent component analysis;(2)time-frequency analysis,a multitaper time-frequency transformation based on the Hanning window,and(3)source localisation.an exact low-resolution brain electromagnetic tomography.The method was verified by comparing aparticipant with CHR-P with a healthy control during the MEG recordings with an eyes-closed resting state.Results Experimental results show that the neural oscillations in CHR-P were significantly abnormal in the theta frequency band(4-7Hz)and the delta frequency band(1-3Hz).Also,relevant brain regions were located in the left occipital lobe and left temporo-occipital junction for the theta band and in the right dorsolateral prefrontal lobe and near orbitofrontal gyrus for the delta band.Conclusions Abnormal neural oscillations based on specific frequency bands and corresponding brain sources may become biomarkers for high-risk groups.Further work will validate these characteristics in CHR-P cohorts.

目的研究T淋巴细胞免疫缺陷在百草枯所致肺纤维化中的作用。方法选择BALB/C(nu/nu)裸鼠与BALB/C(nu/+)小鼠作为实验动物模型,按照20 mg/kg的百草枯一次性灌胃,灌胃1 h后用GC-MS检测血浆中百草枯的药物浓度,在小鼠中毒第7天和第28天取肺组织做病理切片,H&E,MASSON染色。结果2个品系的小鼠在染毒1 h后血浆中的百草枯药物浓度,差异无统计学意义(P>0.05)。第28天的病理切片H&E、MASSON染色显示出2个品系的小鼠在肺纤维化程度方面,差异有统计学意义(P<0.05)。结论T淋巴细胞参与了百草枯所致的肺纤维化的过程,但是T淋巴细胞的缺失没有完全避免百草枯诱导的肺纤维化。T淋巴细胞免疫缺陷不是百草枯所致肺纤维化的决定性因素。

Designing with Nature is an approach linking design and ecology,which focuses on living with nature,caring for nature,and aiming for a sustainable society.China has made eco-city development,eco-restoration,and eco-civilization its legislative priority and its national strategy,investing a US$618 billion in a 5-year period from 2011–2015 that could reach as high as US$1,124 billion dollars in the period of 2016–2020.“Designing with nature”also means that we must,as we are dealing with resources,consider and understand all the impacting factors and ecosystem capacities.China’s biggest challenge has been to restore water quality,aquatic ecosystems,and landscape patterns.Alongside its natural resources and eco-city development,China possesses a solar energy capacity higher than that of any other country in the world,reaching 174 gigawatts by 2018.Solar power is now cheaper than fossil fuels in hundreds of Chinese cities.In this review,we affirm that the nature-driven design put forth by McHarg’s Design with Nature has withstood the test of time,and we aim to renew interest in McHarg’s ideas by arguing for a design of Chinese cities that is,in keeping with Design with Nature,future-oriented,nature-oriented,and sustainability-oriented.

目的探究精神分裂症患者的阴性症状与静息状态下alpha波能量的关系。方法对符合ICD-10诊断标准的13例精神分裂症患者进行静息态(闭眼、清醒)下脑磁图扫描,通过时域下滑动窗短时能量方法计算alpha频段的能量,分别计算出左额叶、右额叶、左颞叶、右颞叶、左顶叶、右顶叶、左枕叶、右枕叶共8个脑区alpha能量值及其能量平均值;采用阳性与阴性症状量表评估精神分裂症患者的临床症状,并根据阴性症状得分将患者分为低阴性症状组(低于中位数)和高阴性症状组(高于中位数)。采用非参数秩和检验(Wilcoxon两样本秩和检验)比较2组alpha波总能量值及8个脑区alpha能量值的差异,采用多因素线性回归分析方法探索右颞区alpha能量与阴性症状的关系,采用协方差分析控制焦虑抑郁因子、受教育年限对阴性症状的影响,采用kendall′s tau-b进行相关分析,分析阴性症状与各脑区能量值的相关性。结果2组右颞叶alpha波能量值比较差异有统计学意义(Z=-2.143,P=0.032)。阴性症状量表分可由右颞叶能量、受教育年限、焦虑抑郁因子分、阳性症状量表分的变化表示(校正r2=0.894),而右颞叶能量值影响显著(t=3.965,P=0.004)。结论精神分裂症患者阴性症状可能与右颞叶能量异常有关。

棘波是癫痫疾病诊断和癫痫灶评估的重要标志,脑磁图设备能更精确地捕捉到癫痫患者在发作间期的棘波信号。然而,目前临床医生仍依赖于手动方法标记棘波信号,缺少便捷离线的多通道棘波检测方法。提出一种脑磁图的多通道棘波检测方法,针对给定时间宽度的多通道脑磁图信号的时间序列可以看作为一个二维矩阵,利用二维主成分分析(2DPCA)方法提取该矩阵的本征特征,再结合最近邻分类器实现离线的多通道棘波信号检测。通过临床癫痫患者的脑磁图信号验证表明,提出的方法棘波信号检测率高达93.23%,且该方法是有效的。

在中国旧时期的发展历程中,唐代是此阶段发展最辉煌的时期,科技、经济、政治、文化等都达到了饱和的地步。正是因为受到政治文化的影响,社会经济得到进一步提高,使得手工业工艺随之进步,因此装饰纹样也受到这些影响产生很大变化,变得丰富多样,种类繁多,主要有动物、植物和几何纹样,其色彩丰富浓艳、华而美丽,给人以典雅和谐的感受。根据当时人类的追求理念,唐代时期将这些装饰纹样运用于家具设计当中。文章中主要分析了唐代的装饰纹样的起源、种类,研究这些装饰纹样如何运用于唐代家具的设计当中,以及唐代家具中装饰纹样的一些装饰特点、工艺和方法等。
