Background Monteggia equivalent lesion represents a group of injury or combined injury patterns that resemble the Monteggia lesion in its presentations and *** Monteggia lesions,the equivalent ones,which share vague definitions and mostly occur as sporadic single case reports in the literature,have not been thoroughly reviewed since Bado first proposed the term,especially in the pediatric *** objective of this review was to elucidate the definition by elaborating on its clinical styles and thus analyzing the mechanism,diagnosis,and management through related *** sources Based on the terms of‘Monteggia equivalent’,‘radial neck fracture’and‘pediatric’,all of the related literature was searched on the PubMed and Google Scholar search *** The advance of the definitions for pediatric Monteggia equivalent lesion(PMEL)was *** functional roles of the ulnar and the related mechanism theories in this injury were *** status of the radiocapitellar joint in this injury was *** to the previous statements,a new classification model was proposed and proper diagnosis and treatment approaches were *** PMEL should be defined as an ulnar fracture at any level combined with a proximal radial *** to the status of the radiocapitellar joint,it could be divided into three *** occult ulnar bowing and delayed radial head dislocation should be a serious concern of *** need is usually *** the ulnar length and securing the radiocapitellar joint are highly recommended.

Objective: To investigate the effect of 5-aminolevulinic(ALA)-photodynamic therapy(PDT) on the expressions of MMP-9, MMP-13 and TIMP-1 of hypertrophic scar model in rabbit ears, and analyze the possible therapeutic mechanisms of ALA-PDT treatment to hypertrophic scars of rabbit ears. Methods: The experimental animals were randomly divided into normal control, negative control, high concentration of ALA-PDT, low concentration of ALA-PDT and PDT groups. The latter three groups received ALA-PDT treatment or PDT treatment once a week for 3 weeks. The specimens of the rabbits were collected respectively 1, 2 and 3 months after treatment to be used for RT-PCR and Western-blot test. Results: 1, 2 and 3 months after PDT treatment, the expressions of MMP-9 and MMP-13(including mRNA and protein) in hypertrophic scar tissues of three treatment groups were significantly higher than those of the negative control group(P<0.01), and the expression of TIMP-1 mRNA and protein of three treatment groups were significantly lower than that of the negative control group(P<0.01). There were also significant differences between high-concentration ALA-PDT treatment group and the low one(P<0.05). Conclusion: ALA-PDT is effective in treating hypertrophic scars of rabbit ears, and its possible therapeutic mechanisms are that ALA-PDT treatment generates oxidation activation effect to activate the activity of MMPs and induces the photoaging of fibroblasts of hypertrophic scar tissues of rabbit ears to inhibit the activity of TIMPs, which causes the up-regulation of MMPs and the down-regulation of TIMPs. Because of this, the degradation of collagen and ECM is accelerated and the formation of scars is suppressed.

In this work,β-Ga_(2)O_(3)thin films were grown on SiO_(2)substrate by atomic layer deposition(ALD)and annealed in N_(2)atmosphere to enhance the crystallization quality of the thin films,which were verified from X-rays diffraction(XRD).Based on the grownβ-Ga_(2)O_(3)thin films,vertical metal-semiconductor-metal(MSM)interdigital photodetectors(PDs)were fabricated and *** PDs have an ultralow dark current of 1.92 pA,ultra-high photo-to-dark current ratio(PDCR)of 1.7×10^(6),and ultra-high detectivity of 4.25×10^(14)Jones at a bias voltage of 10 V under 254 nm deep ultraviolet(DUV).Compared with the horizontal MSM PDs under the same process,the PDCR and detectivity of the fabricated vertical PDs are increased by 1000 times and 100 times,*** addition,the vertical PDs possess a high responsivity of 34.24 A/W and an external quantum efficiency of 1.67×10^(4)%,and also exhibit robustness and repeatability,which indicate excellent *** the effects of electrode size and external irradiation conditions on the performance of the vertical PDs continued to be investigated.

积极交往和消极交往分别会对老年人的心理健康产生有利和不利影响,然而,探讨消极交往的负面作用及其机制的研究相对较少。目前研究主要涉及消极交往的类型(社会隔离、丧偶或离婚)、来源(配偶、子女或朋友)及强度,并探讨感知评估、自尊的中介作用及性别、婚姻、受教育水平等变量的调节作用。社会情感选择理论、优劣势整合理论、社会交换理论及镜中我理论在一定范围内对消极交往的负面作用做出了合理解释。采取"原谅"或"认知疏远"的应对策略能有效缓解消极交往的负面影响。未来研究应进一步考察不同文化背景及社会网络背景下消极交往对老年人心理健康的影响,同时加强对消极交往的理论研究和线上研究,并关注相关的干预研究。

研究硫化氢(H2S)对小鼠背根神经节(DRG)细胞河豚毒素敏感型(TTX-S)钠电流的影响。急性分离小鼠DRG细胞,应用全细胞膜片钳技术,观察H2S供体NaHS对TTX-S钠电流的影响。结果显示,NaHS浓度依赖性地增加TTX-S钠电流,其半数最大激活浓度(EC50)为119μmol/L,Hill系数为1.105;100μmol/L NaHS可使TTX-S钠电流激活曲线向去极化移动约9.8 mV,稳态失活曲线向去级化方向移动约10.4 mV,但对恢复曲线无明显影响。因此,H2S能增加TTX-S钠通道电流,并改变TTX-S钠通道稳态激活和失活动力学特征,这可能是H2S参与疼痛发生发展的机制之一。
