Objective:To study central functional network connections and their alterations in tinnitus patients using ***:Regional homogeneity(ReHo) values on fMRI were obtained from 18 tinnitus patients and 20 age and gender-matched control *** values were compared between tinnitus patients and control subjects to evaluate functional network connection ***:Tinnitus patients showed increased ReHo values in gyrus frontalis inferior and decreased ReHo values in the anterior lobe of cerebellum in comparison with the *** of functional network connection from the gyrus frontalis interior shows stronger connections to the middle brain(FWE,P < 0.001) and right ventral striatum(FEW,P < 0.05,small volume correction).Conclusions:The fMRI results indicate that both auditory and non-auditory centers play important roles in *** connections among the auditory cortex,thalamus,medial temporal gyrus,parahippocampal gyrus and insula may be an underlying cause for the development of tinnitus.

Objective:Subjective tinnitus is characterized by the perception of sound in the absence of any external auditory *** perceived sound may be related to altered intrinsic neural activity generated along the central auditory *** retrospective study was designed to investigate regional homogeneity and functional connectivity in the resting-state brain activity of patients with ***:We recruited tinnitus patients with normal hearing or mild hearing loss(n=17)and age-matched healthy controls(n=20),and examined regional homogeneity and functional connectivity in resting-state brain activity using resting-state functional magnetic resonance imaging *** present study protocol was approved by the Institutional Review Board on Experimental Ethics at Sun Yat-sen University,China(approval ***-KY-KS-2019-083).Results:Compared with normal controls,patients with tinnitus had significantly decreased regional homogeneity in the anterior lobe of the cerebellum and increased homogeneity in the inferior frontal gyrus(P<0.05 corrected at a cluster-level).In addition,tinnitus patients showed enhanced functional connectivity between the inferior frontal gyrus and the ventral striatum and midbrain,as well as increased connectivity between the cerebellum and ventromedial prefrontal cortex(P<0.05 corrected at a cluster-level).We also found decreased connectivity between the cerebellum and the anterior insula compared with controls(P<0.05 corrected at a cluster-level).Conclusion:Abnormal connectivity in non-auditory brain structures,particularly those related to emotion processing,may be associated with tinnitus persistence.

如何计算多孔介质内的应力,能否仅用岩石孔隙度关联岩石孔隙鼓胀系数与岩石骨架压缩系数,一直存在争论。在对这两个问题的争论情况进行总结分析后发现,概念混乱、对工程和力学问题认识不清、数学推导错误是产生争论的主要原因,并指出Terzaghi公式是错误的、不可仅用岩石孔隙度关联岩石孔隙鼓胀系数与岩石骨架压缩系数。同时,提出了岩石鼓胀系数、岩石孔隙鼓胀系数、岩石渗透率鼓增系数、岩石压缩系数、岩石孔隙压缩系数和岩石渗透率压减系数等6个概念,并给出了其物理意义及表达式。讨论认为,用这6个概念可以解决多孔岩石鼓胀压缩特性表征方面出现的混乱现象。

莓叶委陵菜(Potentilla fragarioidis)作为我国北方地区极具开发潜力的乡土地被植物,存在着有性繁殖材料不易获得且繁殖系数较低的问题。而扦插繁殖作为一种无性繁殖手段,能为莓叶委陵菜的快速繁殖提供新的途径。本研究以莓叶委陵菜生长健壮、无病虫害的叶为试验材料,通过正交试验针对不同扦插基质、激素种类及其浓度对莓叶委陵菜叶插生根效果的影响进行探究。结果表明,莓叶委陵菜插穗在扦插45 d后能够形成根系,不同处理水平的扦插基质、激素种类及其浓度间的交互效应对插穗生根效果的影响具有显著差异(P<0.05)。扦插基质是影响莓叶委陵菜叶插生根率的主导因子,而激素种类是影响平均单株生根数、平均单株总根长、最长根长和根系效果指数的主要因素。以草炭+珍珠岩+蛭石(1:1:1)为基质,扦插前使用300 mg·L^(-1)的IBA对插穗进行处理生根效果最佳,该处理方式下扦插生根率达63.33%,平均单株生根数为6.90条,平均单株总根长为27.98 cm,最长根长13.83 cm,根系效果指数达20.50。本研究结果可为莓叶委陵菜无性系繁殖体系的快速建立提供理论依据。

化学观念的建立需要基于化学知识，而初中化学许多知识的呈现是分散的、碎片化的。因此，以观念建构为本的教学已成为以素养导向为目标的初中化学教学的关键问题之一。指向化学观念形成的教学首先需要基于事实形成概念，然后经过深度学习对概念进行关联、抽象概括，形成化学观念。概念图是有相互关联的知识的结构化组合，从概念到运用概念图建立知识内容的结构，再概括抽象形成化学观念，是一个对概念不断加深理解的认识水平结构化发展过程，是实现化学教学素养化的重要途径之一。
