BACKGROUND It remains unclear whether video aids can improve the quality of bystander cardiopulmonary resuscitation(CPR).AIM To summarize simulation-based studies aiming at improving bystander CPR associated with the quality of chest compression and time-related quality *** The systematic review was conducted according to the PRISMA *** relevant studies were searched through PubMed,EMBASE,Medline and Cochrane Library *** risk of bias was evaluated using the Cochrane collaboration *** A total of 259 studies were eligible for inclusion,and 6 randomised controlled trial studies were ultimately *** results of meta-analysis indicated that video-assisted CPR(V-CPR)was significantly associated with the improved mean chest compression rate[OR=0.66(0.49-0.82),P<0.001],and the proportion of chest compression with correct hand positioning[OR=1.63(0.71-2.55),P<0.001].However,the difference in mean chest compression depth was not statistically significant[OR=0.18(-0.07-0.42),P=0.15],and V-CPR was not associated with the time to first chest compression compared to telecommunicator CPR[OR=-0.12(-0.88-0.63),P=0.75].CONCLUSION Video real-time guidance by the dispatcher can improve the quality of bystander CPR to a certain ***,the quality is still not ideal,and there is a lack of guidance caused by poor video signal or inadequate interaction.

Although recurrent traumatic carotid-cavernous fistula （CCF） and its treatment have beenreported sporadically,^1 a complex cavernous sinus dural arteriovenous fistula （DAVF） secondary to balloon embolization of a direct traumatic CCF is rare. In 2005, we treated such a case via transvenous approach using coils and N-buty-2- cyanoacrylate （NBCA）. The causes of recurrent cavernous sinus DAVF and its endovascular approach are discussed.

Recurrent perimedullary arteriovenous fistula at thoracic level

Chinese Medical Journal 2006年第24期119卷 2138-2140页

作者： HAI Jian CHEN Zuo-quan DENG dong-feng pan Qing-gang LING feng Department of Neurosurgery Tongji Hospital Tongji University Shanghai 200065 China

Perimedullary arteriovenous fistula （PMAVF, type Ⅳ spinal cord arteriovenous malformation,SCAVM） is a direct arteriovenous shunt without abnormal vascular connection between the feeding artery and draining vein. Most patients with PMAVF present with a progressive myelopathy caused by venous hypertension, resulting in disabling deficits and incurable complete transverse myelopathy. The lesion is usually located on the surface of the spinal cord or under the pia mater at the level of the conus medullaris or cauda equina, thoracic PMAVF is rarely encountered. Most PMAVFs are fed by the anterior spinal artery （ASA）, posterior spinal artery （PSA）, or both Multiple arterial feeders from the ASA can make the treatment of the disease difficult From August 2004 to February 2005, we treated a patient with a recurrent PMAVF （type Ⅳb） at the thoracic level with multiple blood supply.

Photocatalytic oxygen reduction for hydrogen peroxide （H2O2） synthesis presents a green and costeffective production ***,achieving highly selective H2O2synthesis remains challenging,necessitating precise control over free radical reaction pathways and minimizing undesirable oxidative ***,we report for the visible light-driven simultaneous co-photocatalytic reduction of O2to H2O2and oxidation of biomass using the atomic rubidium-nitride modified carbon nitride（CNRb）.The optimized CNRb catalyst demonstrates a record photoreduction rate of 8.01 mM h-1for H2O2generation and photooxidation rate of 3.75 mM h-1for furfuryl alcohol to furoic acid,achieving a remarkable solar-to-chemical conversion （SCC） efficiency of up to 2.27%.Experimental characterizations and DFT calculation disclosed that the introducing atomic Rb–N configurations allows for the high-selective generation of superoxide radicals while suppressing hydroxyl free radical *** is because the Rb–N serves as the new alternative site to perceive a stronger connection position for O2adsorption and reinforce the capability to extract protons,thereby triggering a high selective redox product *** study holds great potential in precisely regulating reactive radical processes at the atomic level,thereby paving the way for efficient synthesis of H2O2coupled with biomass valorization.

背景:关节置换后放置引流已经作为一种常规应用于髋、膝关节置换后,然而,引流管作为外界与关节相通的潜在通道,可能成为细菌等病原体入侵关节腔的门户。目的:评价引流管在人工膝关节置换术中的临床意义及安全性。方法:对80例需行人工膝关节置换的患者按照住院号的单双号随机分为引流组(38例)与非引流组(42例),根据公式计算并对关节置换后失血量、需输血人数及输血量、置换后并发症及膝关节功能的恢复情况进行统计分析。结果与结论:出院后继续随访2年,其中非引流组2例失访,78例患者纳入结果分析。关节置换后总失血量、需输血人数、输血量,引流组多于非引流组;置换后第3天膝关节主动活动度,引流组要大于非引流组;置换后血红蛋白变化值及末次随访两组患者KSS评分差异无显著性意义。结果表明人工膝关节置换后放置引流将增加后的失血及输血,但在置换后早期膝关节功能的恢复方面可能存在积极的意义,远期膝关节功能评分及置换后并发症两组差异无显著性意义。

背景:乙醇已成为股骨头缺血性坏死的致病因素,其所致的骨髓内脂质代谢异常可能是股骨头缺血性坏死起病的重要原因,但机制尚未完全明确。目的:从分子水平观察在乙醇作用下脂肪细胞结构功能的变化,以期分析酒精性股骨头坏死的发病机制。方法:采用原代脂肪细胞体外培养技术,取大白兔股骨头髓内脂肪组织,分离获取脂肪细胞,以油红O染色行细胞表型鉴定。取传代稳定的髓内脂肪细胞,将盖玻片切割成10mm×10mm,种植前置入24孔培养板孔内,分为乙醇组和对照组,每组24孔,每孔为1个样本。对照组不加乙醇,乙醇组加入0.15mol/L乙醇,分别于4,6,8,10d更换培养液,换液时不再加入乙醇,均培养至10d。培养终止后,取出盖玻片行油红O染色,光镜下观察脂肪细胞形态并计数。结果与结论:随着时间延长,乙醇组脂肪细胞数量明显多于对照组(P<0.001),2组小脂滴均逐渐增多、增大,但乙醇组更明显。培养4,6,8,10d的髓内脂肪细胞数量乙醇组分别为(200.90±24.60),(1102.30±76.73),(1160.30±28.37),(1199.70±44.74)个/cm^2;对照组分别为(99.80±10.82),(0.40±94.71),(1000.20±41.85),(1059.80±26.79)个/cm^2,脂肪细胞数量随乙醇作用的时间延长而增多。提示乙醇能够促进髓内脂肪细胞增殖肥大,这可能是长期酗酒后股骨头骨髓内脂肪组织增多,骨内压增加,血流灌注减少,导致缺血,从而发生股骨头坏死的主要原因。

The role of axon guidance molecules in the pathogenesis of epilepsy

引用

Neural Regeneration Research 2025年第5期20卷 1244-1257页

作者： Zheng Liu Chunhua pan Hao Huang Department of Neurology Affiliated Hospital of Zunyi Medical UniversityZunyiGuizhou ProvinceChina

Current treatments for epilepsy can only manage the symptoms of the condition but cannot alter the initial onset or halt the progression of the disease. Consequently, it is crucial to identify drugs that can target novel cellular and molecular mechanisms and mechanisms of action. Increasing evidence suggests that axon guidance molecules play a role in the structural and functional modifications of neural networks and that the dysregulation of these molecules is associated with epilepsy susceptibility. In this review, we discuss the essential role of axon guidance molecules in neuronal activity in patients with epilepsy as well as the impact of these molecules on synaptic plasticity and brain tissue remodeling. Furthermore, we examine the relationship between axon guidance molecules and neuroinflammation, as well as the structural changes in specific brain regions that contribute to the development of epilepsy. Ample evidence indicates that axon guidance molecules, including semaphorins and ephrins, play a fundamental role in guiding axon growth and the establishment of synaptic connections. Deviations in their expression or function can disrupt neuronal connections, ultimately leading to epileptic seizures. The remodeling of neural networks is a significant characteristic of epilepsy, with axon guidance molecules playing a role in the dynamic reorganization of neural circuits. This, in turn, affects synapse formation and elimination. Dysregulation of these molecules can upset the delicate balance between excitation and inhibition within a neural network, thereby increasing the risk of overexcitation and the development of epilepsy. Inflammatory signals can regulate the expression and function of axon guidance molecules, thus influencing axonal growth, axon orientation, and synaptic plasticity. The dysregulation of neuroinflammation can intensify neuronal dysfunction and contribute to the occurrence of epilepsy. This review delves into the mechanisms associated with
