The current cadaveric report describes an unusual morphology of the sartorius muscle (SM), the biceps-bicaudatus variant. The SM had two (lateral and medial) heads, with distinct tendinous origins from the anterior superior iliac spine. The lateral head was further split into a lateral and a medial bundle. The anterior cutaneous branch of the femoral nerve emerged between the origins of the lateral and medial heads. SM morphological variants are exceedingly uncommon, with only a few documented cases in the literature, and several terms used for their description. Although their rare occurrence, they may play an important role in the differential diagnosis of entrapment syndromes, in cases of neural compressions, such as meralgia paresthetica, while careful dissection during the superficial inter-nervous plane of the direct anterior hip approach is of utmost importance, to avoid adverse effects due to the altered SM morphology.

目前的尸体报告描述了萨尔图里斯肌(Sartorius muscle,SM)的一种不同寻常的形态,即肱二头肌-双头肌变体(biceps-bicaudatus variant)。腓肠肌有两个头(外侧头和内侧头),与髂前上棘有明显的肌腱起源。外侧头又分为外侧束和内侧束。股神经前皮支位于外侧头和内侧头的起源之间。SM形态变异极为罕见,文献中仅有几例记录在案,有多个术语用于描述。尽管其发生率极低,但在神经压迫病例(如麻痹性肢痛症)中,它们可能在夹层综合征的鉴别诊断中发挥重要作用,而在髋关节前方直接入路的浅表神经间平面中进行仔细解剖则至关重要,以避免因 SM 形态改变而产生不良影响。

The world has witnessed tremendous advancements in nano-base applications. Zinc oxide nanoparticles (ZON) are widely used in food industry and medicine. Although their application is of important value, they may cause toxicity to body tissues. Peripheral blood mononuclear cells (PBMCs) proved its efficacy in tissue regeneration especially when it is preconditioned by activated platelet supernatant (APS). The aim of this study is to evaluate the effect of ZON on the gastric mucosa and the therapeutic role of the PBMCs preconditioned by APS in rats. Ten rats were donors and fifty rats were recipients. The recipients were divided into; control group, ZON group (10 mg/kg/day orally for five days) and preconditioned PBMCs group (1×107 once intravenously 24 hours after ZON). Gastric specimens were processed for histological, immunohistochemical, biochemical and quantitative real-time polymerase chain reaction studies. ZON group showed marked structural changes in the gastric mucosa. There was desquamation or deep ulceration of the epithelium. Cytoplasmic vacuoles and pyknotic nuclei were in glandular cells. Reduced proliferating cell nuclear antigen and increased tumor necrosis factor-α were in epithelial cells. There were significant elevation in malondialdahyde and reduction in glutathione, superoxide dismutase, and catalase. Enhancement in mRNA expression of nuclear factor kappa-B and cyclooxygenase-2 was detected. The preconditioned PBMCs group showed significant improvement of all parameters. So, ZON had cytotoxic effects on the gastric mucosa and the preconditioned PBMCs had a therapeutic effect on gastric mucosal damage after ZON.

全球在纳米基础应用方面取得了巨大进步。纳米氧化锌(ZON)被广泛应用于食品工业和医药领域。虽然其应用具有重要价值,但可能会对人体组织造成毒性。事实证明,外周血单核细胞(PBMCs)在组织再生方面具有功效,尤其是在使用活化血小板上清液(APS)进行预处理的情况下。本研究旨在评估 ZON 对大鼠胃黏膜的影响以及经 APS 预处理的 PBMCs 的治疗作用。十只大鼠为供体,五十只大鼠为受体。受体分为:对照组、ZON 组(口服 10 毫克/千克/天,连续五天)和预处理 PBMCs 组(ZON 24 小时后静脉注射一次,每次 1×107)。对胃标本进行组织学、免疫组化、生化和实时定量聚合酶链反应研究。ZON 组的胃黏膜出现了明显的结构变化。上皮出现脱屑或深度溃疡。腺细胞出现胞浆空泡和细胞核萎缩。上皮细胞中的增殖细胞核抗原减少,肿瘤坏死因子-α增加。丙二醛明显升高,谷胱甘肽、超氧化物歧化酶和过氧化氢酶降低。检测到核因子 kappa-beta 和环氧化酶-2 的 mRNA 表达增强。预处理 PBMCs 组的所有参数都有明显改善。因此,ZON 对胃黏膜有细胞毒性作用,而预处理的 PBMCs 对 ZON 后的胃黏膜损伤有治疗作用。

Methamphetamine (METH) can potentially disrupt neurotransmitters activities in the central nervous system (CNS) and cause neurotoxicity through various pathways. These pathways include increased production of reactive nitrogen and oxygen species, hypothermia, and induction of mitochondrial apoptosis. In this study, we investigated the long-term effects of METH addiction on the structural changes in the amygdala of postmortem human brains and the involvement of the brain- cAMP response element-binding protein/brain-derived neurotrophic factor (CREB/BDNF) and Akt-1/GSK3 signaling pathways. We examined ten male postmortem brains, comparing control subjects with chronic METH users, using immunohistochemistry, real-time polymerase chain reaction (to measure levels of CREB, BDNF, Akt-1, GSK3, and tumor necrosis factor-α [TNF-α]), Tunnel assay, stereology, and assays for reactive oxygen species (ROS), glutathione disulfide (GSSG), and glutathione peroxidase (GPX). The findings revealed that METH significantly reduced the expression of BDNF, CREB, Akt-1, and GPX while increasing the levels of GSSG, ROS, RIPK3, GSK3, and TNF-α. Furthermore, METH-induced inflammation and neurodegeneration in the amygdala, with ROS production mediated by the CREB/BDNF and Akt-1/GSK3 signaling pathways.

甲基苯丙胺(METH)可以潜在地破坏中枢神经系统(CNS)的神经递质活动,并通过多种途径引起神经毒性。这些途径包括增加活性氮和活性氧的产生、低温和诱导线粒体凋亡。在这项研究中,我们研究了冰毒成瘾对死后人脑杏仁核结构变化的长期影响,以及脑- cAMP反应元件结合蛋白/脑源性神经营养因子(CREB/BDNF)和Akt-1/GSK3信号通路的参与。我们使用免疫组织化学、实时聚合酶链反应(测量CREB、BDNF、Akt-1、GSK3和肿瘤坏死因子-α [TNF-α]的水平)、隧道试验、体视学和活性氧(ROS)、谷胱甘肽二硫(GSSG)和谷胱甘肽过氧化物酶(GPX)的测定,对10个男性死后的大脑进行了检测,并将对照组与慢性冰毒用户进行了比较。结果显示,甲基安非他明显著降低BDNF、CREB、Akt-1和GPX的表达,同时增加GSSG、ROS、RIPK3、GSK3和TNF-α的水平。此外,甲基苯丙胺诱导的杏仁核炎症和神经变性,通过CREB/BDNF和Akt-1/GSK3信号通路介导ROS的产生。

The pterygomandibular raphe (PMR) is a tendinous structure connecting the bucinator and the superior pharyngeal constrictor muscles. With its implications in the spread of oral cancer, the proper treatment of obstructive sleep apnea, and dental procedures, it is important to obtain a thorough understanding of the PMR. We reviewed the existing literature to compile the published information regarding its anatomy, embryology, imaging, variations, functions, pathologies, and clinical relevance of the pterygomandibular raphe.

翼下颌剑突(PMR)是连接颊肌和咽上收缩肌的腱性结构。翼下颌下腺剑突对口腔癌的扩散、阻塞性睡眠呼吸暂停的正确治疗以及牙科手术都有影响,因此全面了解翼下颌下腺剑突非常重要。我们查阅了现有文献,汇编了有关翼下颌剑突的解剖、胚胎学、影像学、变异、功能、病理和临床相关性的已发表信息。

The aim of this study was to identify the anatomical feature of retaining ligament and fat compartment on the lower eyelid and infraorbital region using a histological method, and to investigate clear definitions for them which could be used generally in the clinical area. Eighteen specimens from eight fresh Korean cadavers were stained with Masson trichrome or hematoxylin and eosin. The ligamentous and fascial fibrous tissue were clearly identified. The ligamentous fibrous tissue which traversed in the superficial and deep fat layer was skin ligament and orbicularis retaining ligament (ORL). The fascial fibrous tissue enclosed the orbicularis oculi muscle (OOc) and circumferencial adipose tissue. Based on the ligamentous and fascial structure, three fat compartments, septal, suborbicularis oculi and infraorbital fat compartment, could be identified. The OOc attached to orbital rim and dermis by ORL and skin ligament, and the muscle fascicle and fat fascicle provided the connection point to the ORL and skin ligament as enclosing all muscle and fat tissue. The combination of the force made by the skin ligament in the lower eyelid and ORL may decide the level and form of the infraorbital grooves.

本研究的目的是利用组织学方法确定下眼睑和眶下区保留韧带和脂肪区的解剖特征,并研究可在临床上普遍使用的明确定义。研究人员用 Masson 三色或苏木精和伊红对来自 8 具新鲜韩国尸体的 18 份标本进行了染色。韧带纤维组织和筋膜纤维组织清晰可辨。穿过浅层和深层脂肪的韧带纤维组织是皮肤韧带和眼轮匝肌固定韧带(ORL)。筋膜纤维组织包裹着眼轮匝肌和眼周脂肪组织。根据韧带和筋膜结构,可以确定三个脂肪区,即眼轮匝肌间隔、眼轮匝肌下和眶下脂肪区。眼轮匝肌通过眼轮匝肌韧带和皮肤韧带与眼眶边缘和真皮相连,肌肉筋膜和脂肪筋膜提供了与眼轮匝肌韧带和皮肤韧带的连接点,将所有肌肉和脂肪组织包围起来。下眼睑皮肤韧带和眼轮匝肌所受的力可决定眶下沟的水平和形态。

Knowledge of anatomical variations is important so as to avoid potential iatrogenic injury or misdiagnosis on imaging. Here we report an unusual finding and relationship between the tibial nerve and popliteal vein. During the routine dissection of an adult cadaver, it was noted that a branch of the tibial nerve in the popliteal fossa pierced the most distal part of the popliteal vein. This unusual finding is described and relevant reports in the literature discussed. Our hopes are that such a report might help surgeons avoid injury to such a fenestrated popliteal vein and the tibial nerve branch traveling through it therefore decreasing patient morbidity.

对解剖变异的了解非常重要,可避免潜在的先天性损伤或影像学误诊。在此,我们报告了一个不寻常的发现以及胫神经和腘静脉之间的关系。在对一具成人尸体进行常规解剖时,我们发现腘窝中的胫神经分支刺穿了腘静脉的最远处。本文对这一不寻常的发现进行了描述,并讨论了文献中的相关报道。我们希望这样的报告可以帮助外科医生避免损伤这种腘静脉瘘管和穿过瘘管的胫神经分支,从而降低患者的发病率。

Bladder exstrophy is a rare congenital condition of the pelvis, bladder, and lower abdomen that opens the bladder against the abdominal wall, produces aberrant growth, short penis, upward curvature during erection, wide penis, and undescended testes. Exstrophy affects 1/30,000 newborns. The bladder opens against the abdominal wall in bladder exstrophy, a rare genitourinary condition. This study is vital to provide appropriate therapy choices as a basis to improve patient outcomes. This study may explain bladder exstrophy and provide treatment.

膀胱萎缩是一种罕见的先天性骨盆、膀胱和下腹部疾病,会使膀胱紧贴腹壁开放,导致发育畸形、阴茎短小、勃起时向上弯曲、阴茎宽大和睾丸下垂。每 30,000 名新生儿中就有 1 人患有睾丸萎缩症。膀胱萎缩症是一种罕见的泌尿生殖系统疾病,患者的膀胱紧贴腹壁开放。这项研究对于提供适当的治疗选择至关重要,是改善患者预后的基础。这项研究可以解释膀胱外翻并提供治疗方法。膀胱外翻、分泌性胎盘、泄殖腔外翻和其他胚胎畸形构成了膀胱外翻-黑桃复合体。间质层在妊娠头三个月不会从外胚层和内胚层移出,从而影响泄殖腔膜。胚胎学问题决定了膀胱外翻-膀胱外翻复合体,它类似于膀胱外翻、典型膀胱外翻、泄殖腔外翻和其他疾病。泌尿生殖器腹侧体壁异常会暴露膀胱粘膜,导致膀胱萎缩。刺猬级联通路、Wnt 信号、FGF、BMP4、Alx4、Gli3 和 ISL1 的基因突变会导致腹侧体壁闭合和膀胱功能衰竭。高龄产妇、吸烟妈妈和高体重指数等外部因素也与膀胱外翻有关。丙戊酸会增加膀胱外翻的风险;怀孕期间的化学物质和污染物可能会增加膀胱外翻的风险。尽管存在这些风险因素,但膀胱萎缩并没有确定的原因。膀胱萎缩再造术可封闭膀胱、改善肠道功能、重建阴道区域并恢复排尿功能。

Vascular dementia (VaD) is characterized by progressive memory impairment, which is associated with microglia-mediated neuroinflammation. Polyphenol-rich natural plants, which possess anti-inflammatory activities, have attracted scientific interest worldwide. This study investigated whether Rubus fruticosus leaf extract (RFLE) can attenuate VaD. Sprague-Dawley rats were separated into five groups: SO, sham-operated and treated with vehicle; OP, operated and treated with vehicle; RFLE-L, operated and treated with low dose (30 mg/kg) of RFLE; RFLE-M, operated and treated with medium dose (60 mg/kg) of RFLE; and RFLE-H, operated and treated with high dose (90 mg/kg) of RFLE. Bilateral common carotid artery and hypotension were used as a modeling procedure, and the RFLE were intraorally administered for 5 days (preoperative 2 and postoperative 3 days). The rats then underwent memory tests including the novel object recognition, Y-maze, Barnes maze, and passive avoidance tests, and neuronal viability and neuroinflammation were quantified in their hippocampi. The results showed that the OP group exhibited VaD-associated memory deficits, neuronal death, and microglial activation in hippocampi, while the RFLE-treated groups showed significant attenuation in all above parameters. Next, using BV-2 microglial cells challenged with lipopolysaccharide (LPS), we evaluated the effects of RFLE in dynamics of proinflammatory mediators and the upstream signaling pathway. RFLE pretreatment significantly inhibited the LPS-induced release of nitric oxide, TNF-α, and IL-6 and upregulation of the MAPKs/NF-κB/iNOS pathway. Collectively, we suggest that RFLE can attenuate the histologic alterations and memory deficits accompanied by VaD, and these roles are, partly due to the attenuation of microglial activation.

血管性痴呆(VaD)的特征是进行性记忆障碍,这与小胶质细胞介导的神经炎症有关。富含多酚的天然植物具有抗炎活性,引起了全世界的科学兴趣。本研究探讨了悬钩子叶提取物(RFLE)是否能减轻VaD。将Sprague-Dawley大鼠分为5组:SO组、假手术组和赋形剂组;OP,与车辆一起操作和处理;RFLE-L,用低剂量(30mg/kg)RFLE操作和治疗;RFLE-M,用中等剂量(60mg/kg)的RFLE进行手术和治疗;和RFLE-H,用高剂量(90mg/kg)的RFLE操作和治疗。采用双侧颈总动脉和低血压作为建模程序,术中给予RFLE 5天(术前2天和术后3天)。然后,大鼠接受了记忆测试,包括新型物体识别、Y迷宫、巴恩斯迷宫和被动回避测试,并对其海马中的神经元活力和神经炎症进行了量化。结果显示,OP组在海马中表现出与VaD相关的记忆缺陷、神经元死亡和小胶质细胞活化,而RFLE治疗组在所有上述参数上都表现出显著的衰减。接下来,使用脂多糖(LPS)攻击的BV-2小胶质细胞,我们评估了RFLE在促炎介质动力学和上游信号通路中的作用。RFLE预处理显著抑制LPS诱导的一氧化氮、TNF-α和IL-6的释放,并上调MAPKs/NF-κB/iNOS通路。总之,我们认为RFLE可以减轻VaD引起的组织学改变和记忆缺陷,这些作用部分是由于小胶质细胞激活的减弱。

The intercostobrachial nerve (ICBN) originates from the second intercostal nerve's lateral cutaneous branch, while the median nerve (MN) typically arises from the brachial plexus's lateral and medial roots. The medial cutaneous nerve of the arm, a branch of the medial cord of the brachial plexus, often connects with the ICBN. Variations were observed during the dissection of a 50-year-old male cadaver, including MN having two lateral roots (LR), LR1 and LR2, joining at different levels. Three ICBNs innervated the arm in this case, with the absence of the medial cutaneous nerve of the arm compensated by branches from the medial cutaneous nerve of the forearm. Understanding these anatomical variations is crucial for surgical procedures like brachioplasty, breast augmentation, axillary lymph node dissection, and orthopedic surgery. Surgeons and medical professionals must be aware of these variations to enhance preoperative planning, minimize complications, and improve patient outcomes in these procedures.

肋间臂神经(ICBN)起源于第二肋间神经的外侧皮支,而正中神经(MN)通常起源于臂丛神经的外侧和内侧根。臂内侧皮神经是臂丛内侧索的一个分支,通常与ICBN相连。在解剖一具50岁男性尸体的过程中观察到了变化,包括具有两个侧根(LR)的MN,LR1和LR2,在不同水平连接。在这种情况下,三个ICBN支配手臂,手臂内侧皮神经的缺失由前臂内侧皮神经分支补偿。了解这些解剖变异对于腕骨成形术、隆胸术、腋窝淋巴结清扫术和骨科手术等外科手术至关重要。外科医生和医疗专业人员必须意识到这些变化,以加强术前计划,最大限度地减少并发症,并在这些手术中改善患者的预后。
