Morbus Gaucher is an inherited disease of fat deposition caused by an autosomal recessive defect in the gene encoding the enzyme β-glucocerebrosidase, responsible for the accumulation of glucosylceramides in reticuloendothelial cells, turning this multidimensional disease into a debilitating Gaucher disease and are found mainly in the spleen, liver, bone marrow and rarely in the lung. The level of glucocerebrosidase enzymatic activity in patients with Gaucher is seen to reach around 5–25% of normal activity. Measurement of this level in leukocytes or cutaneous fibroblasts is considered the “Gold Standard” for Gaucher diagnosis. Although Gaucher is the most common lysosomal deposition disease it remains rare and most cases present with a gradual installation of the clinic which explains the delay in diagnosis. It is very important to include Gaucher as a possible diagnosis in cases of splenomegaly and / or thrombocytopenia. The study, "Predicting the probability of Gaucher disease in subjects with splenomegaly and thrombocytopenia," published in Scientific Reports, managed to reconstruct a diagnostic algorithm that managed to identify the relationship between platelet count, ferritin and transferrin saturation, thus making it possible to achieve a possible approach regarding the diagnosis of GD, which for the sake of truth continues to be an undiagnosed / misdiagnosed pathology.
Morbus Gaucher是一种脂肪沉积的遗传性疾病,由编码β-葡糖脑苷酶的基因的常染色体隐性缺陷引起,该酶负责网状内皮细胞中葡糖神经酰胺的积累,将这种多层面的疾病转变为使人衰弱的Gaucher病,主要在脾、肝、骨髓中发现,很少在肺中发现。戈谢患者的葡糖脑苷酶活性水平约为正常活性的5-25%。白细胞或皮肤成纤维细胞中这种水平的测量被认为是戈谢诊断的“黄金标准”。尽管Gaucher是最常见的溶酶体沉积病,但它仍然很罕见,大多数病例都是随着临床的逐步安装而出现的,这解释了诊断的延迟。将Gaucher作为脾肿大和/或血小板减少症的可能诊断是非常重要的。发表在《科学报告》上的这项题为“预测脾肿大和血小板减少症受试者患戈谢病的概率”的研究,成功地重建了一种诊断算法,该算法能够识别血小板计数、铁蛋白和转铁蛋白饱和度之间的关系,从而有可能实现一种诊断GD的可能方法,为了真实起见,它仍然是一种未诊断/误诊的病理。

Why only a man turned out to be the owner of mind? 为什么只有男人才是思想的主人?

It is considered that the main distinguishing feature of Homo sapiens from other living beings is the presence of his mind. There are many hypotheses regarding the origin of the human mind. The complexity of the problem lies in the fact that it is impossible to experimentally test any of the existing hypotheses. Perhaps we will never fully know how the human mind arose, but it is necessary to strive for this. Here we discuss the possible causes of the origin of a large brain in modern man, implying that the mind is ultimately a product of the human brain. We believe that in order for such a large brain to arise, profound and possibly unique changes in the genome and in the human body had to occur, which did not take place in other higher primates. The role of the evolution of the karyotype and heterochromatin part of the genome in the immediate ancestors of Homo s. sapiens, which led to an increase in the level of heat conductivity of their bodies changed the existing mechanisms of thermoregulation and led to the appearance of hairless skin, which, together, led to a sharp increase in the size of the brain, with the ensuing consequences, is discussed. We believe that the increase of the human brain size was not the result of drastically changes of the structural genes. Most likely it was the consequence of more ordinary events, such as evolution of karyotype, constitutive heterochromatin in chromosomes, human body heat conductivity, skin and thermoregulation. An experimental test is proposed to test the hypothesis put forward.
人们认为智人区别于其他生物的主要特征是他的思想的存在。关于人类思维的起源有许多假设。这个问题的复杂性在于不可能用实验来检验任何现有的假设。也许我们永远无法完全了解人类思维是如何产生的,但有必要为此而努力。在这里,我们讨论了现代人大大脑起源的可能原因,这意味着思想最终是人类大脑的产物。我们认为,为了产生如此大的大脑,基因组和人体必须发生深刻而可能独特的变化,这在其他高等灵长类动物中没有发生。讨论了智人直系祖先基因组核型和异染色质部分的进化所起的作用,这导致了他们身体热传导水平的增加,改变了现有的热调节机制,导致了无毛皮肤的出现,这两者一起导致了大脑大小的急剧增加,以及随之而来的后果。我们认为,人类大脑大小的增加并不是结构基因急剧变化的结果。最有可能的是,这是更普通事件的结果,如核型的进化,染色体中的组成异染色质,人体的热传导性,皮肤和体温调节。提出了一个实验检验来检验所提出的假设。

Ischemic heart disease is the leading cause of death worldwide, its frequency has increased in recent years. Right bundle branch block occurs in the general population and may be an incidental finding on the electrocardiogram or a manifestation of heart or lung disease with or without associated symptoms. A case of a 57-year-old man with a health history that begins with epigastric pain and an Electrocardiogram with right bundle branch block is presented. He is diagnosed with acute myocardial infarction and is treated urgently. Within two hours of the start of the event, the patient dies. Right bundle branch block can be the debut of an acute myocardial infarction while it casts a shadow over its prognosis.
缺血性心脏病是全球死亡的主要原因,近年来其发病率有所上升。右束支传导阻滞发生在普通人群中,可能是心电图上的偶然发现,也可能是伴有或不伴有相关症状的心脏或肺部疾病的表现。一例57岁男性,其健康史始于上腹痛,心电图显示右束支传导阻滞。他被诊断为急性心肌梗死,正在接受紧急治疗。事件开始后两小时内,患者死亡。右束支传导阻滞可能是急性心肌梗死的首次出现,但它给其预后蒙上了阴影。

Background and aim: Glucose-6-Phosphate Dehydrogenase (G6PD) deficiency and sickle cell disease are two genetic diseases of the red blood cell that both cause hemolytic anemia. The objective of this study is to determine the clinico- biological impact of G6PD deficiency on sickle cell disease in childrenin Kinshasa. Materials and method: This is a case-control analytical study of 103 G6PD-deficient sickle cell patientsand 309 non-G6PD- deficientsickle cell patients. Analysis of G6PD activitywas performed by ELISA, and hemoglobin electrophoresis by capillaris to confirm sickle cell disease.For all children, sociodemographic, clinical and biological variables were analyzed. Results: The mean age of sickle cell deficient and non-deficient patients was 9.82±4.5 years and 9.48±3.8 years respectively. There were slightly more female sickle cell deficient patients (55.2%) while in the non- deficient group, there was a male predominance (51.8%) but no statistically significant difference (p>0.05). All morbid events occurring in sickle cell patients were greater in the G6PD deficiency group (p˂0.05). Evaluated antecedent complications occurringin sickle cell patients wereassociated with G6PD deficiency (p˂0.05),except for stroke.No statistically significant difference was noted in physicalsigns between sicklecell deficient and non-deficient groups(p>0.05). The hemogramshowed no difference between the two groups in steady state and the hemolysis markers evaluated also showed no significant differences in steady state (p>0.05) between the two groups. Conclusion: G6PD deficiency aggravates the acute clinical manifestations and complications of sickle cell disease withoutaffecting the occurrence of stroke. And has no impact on the hematological parameters of sickle cell disease children in stationary phase.

Why are there so Many non-coding DNAs with Repeating Sequences of Nucleotides in the Genome of Higher Eukaryotes? 为什么在高等真核生物的基因组中有这么多具有重复核苷酸序列的非编码dna ?

There are many questions regarding the biological roles of non-coding DNAs (ncDNAs) in the eukaryotic genome. It is noteworthy that ncDNAs, despite the overwhelming majority in the genome is still a mysterious object. From simple theoretical considerations, it follows that this vast class of ncDNAs should play some important role in the vital activity of higher eukaryotes. If by their nature they are not capable create specific biological products (proteins, enzymes or RNAs), then they must form some non-specific structures in the cell that are important in the vital activity of higher eukaryotes. Thus, from our point of view, excess ncDNAs were fixed in the genome of higher eukaryotes mainly due to the presence in their composition of sites with repetitive sequences of nucleotides and their wide variability in the population, which ultimately played a decisive role in the emergence of the eukaryotic nucleus and cells, biological sex and species, large multicellular and warm-blooded organisms, up to modern humans.
关于非编码dna (ncdna)在真核生物基因组中的生物学作用存在许多问题。值得注意的是,尽管ncdna在基因组中占绝大多数,但它仍然是一个神秘的物体。从简单的理论考虑,这类庞大的ncdna应该在高等真核生物的生命活动中发挥重要作用。如果它们的性质不能产生特定的生物产物(蛋白质、酶或rna),那么它们必须在细胞中形成一些非特异性结构,这些结构在高级真核生物的重要活动中很重要。因此,从我们的角度来看,过量的ncdna被固定在高等真核生物的基因组中,主要是由于它们的核苷酸重复序列位点的组成以及它们在种群中的广泛变异性,这最终在真核细胞核和细胞、生物性别和物种、大型多细胞和温血生物,直到现代人类的出现中发挥了决定性作用。

Chronic neuro-inflammation cause the neural cell death including dopaminergic cells and ultimate results Parkinson’s disease (PD). In an MPTP-induced PD animal model an increased peripheral pro-inflammatory M1 macrophages (M1- MFs) were found. Polarization of this M1-type of MFs to anti-inflammatory M2-type revealed a potential therapeutic benefit for PD patients. Here we highlight the concept of MFs re-education as a method of PD therapies, and how we can deploy our knowledge to find out therapeutic regimen for PD treatment.

As is known Homo s. sapiens is the only living creature that has managed to inhabit the whole of the Earth, while remaining a single tropical biological species. The case is really unique considering that all this happened in an unprecedentedly short (by evolutionary scale) period of time, if the beginning of this process is considered to be its exit outside of East Africa about 30 000 - 50 000 years ago. However, science does not know everything about how all this happened to a species that itself emerged relatively recently (130 000 - 200 000 year ago) and nevertheless managed to do what other species failed to do. One of the important questions that arises when comprehending this phenomenon is reduced to the following: what features of a human him to make such an unprecedented breakthrough in the settlement of the planet? In particular, what biological advantages or prerequisites did the ancestors of modern man possess when they decided to leave Africa? Usually, such advantages include its large neocortex with a high-functioning mind, high physiological plasticity, perfect system of physiological thermoregulation, the structural features of the upper limbs, unique sexual and reproductive behavior, etc., etc. Without disputing the importance of these well-studied advantages, we would like to add to this list two more that could play an important role in the settlement of all climatogeographic zones of Africa and Eurasia by man: variability of the skin color and the level of heat conductivity of his body. We believe that the skin color and the heat-conducting ability of the human body are involved in his adaptation to heat and cold climates through thermoregulation systems. After all, the skin is the largest human organ that is in direct contact with the ambient temperature.
众所周知,智人是唯一一种能够在整个地球上生存的生物,同时仍然是一个单一的热带生物物种。考虑到这一切发生在前所未有的短时间内(从进化的角度来看),如果这一过程的开始被认为是大约3万至5万年前它离开东非,那么这种情况真的很独特。然而,科学并不完全了解这一切是如何发生在一个相对较新(13万至20万年前)出现的物种身上的,尽管如此,它还是成功地做到了其他物种没有做到的事情。在理解这一现象时,出现的一个重要问题可以归结为以下几个问题:人类的哪些特征能够在地球定居方面取得如此前所未有的突破?特别是,当现代人的祖先决定离开非洲时,他们拥有什么生物学优势或先决条件?通常,这些优势包括其巨大的新皮层,具有高功能的心智、高生理可塑性、完善的生理体温调节系统、上肢的结构特征、独特的性行为和生殖行为等,我们想在这个列表中再添加两个可能在人类定居非洲和欧亚大陆所有气候地理区域中发挥重要作用的因素:皮肤颜色的可变性和身体的导热水平。我们认为,肤色和人体的导热能力与他通过体温调节系统适应冷热气候有关。毕竟,皮肤是与环境温度直接接触的最大人体器官。

Background: In children, Staphylococcus aureus infects growing, long bones causing osteomyelitis. While the symptoms are recognizable, its occurrence in children is quite rare. Purpose: To highlight a novel case of pediatric osteomyelitis with delirium. Presentation: A 10-year old male presented to the emergency room with a fever and limited range of motion, swelling, and pain in the right clavicular region. His condition declined over two days, developing tachycardia and delirium. Laboratory and imaging studies revealed an abscess in the chest wall as well as severe myositis and cellulitis. The patient was treated with surgical drainage and IV antibiotics, leading to resolution of the patient’s condition. Conclusion: This case report will help physicians in the pediatric or emergency department settings consider, identify, and accurately assess patients for osteomyelitis in developing treatment plans to resolve their patients’ conditions.

Primary CNS lymphoma presents unique challenges for the clinician. New evidence has emerged regarding the appropriate workup, management considerations, and treatment. In this paper, we highlight the clinical presentations, disease prognosis, and management considerations. We place specific emphasis on the decision tree for immunocompetent and immunocompromised. The key imaging characteristics are discussed. Once biopsy prove lymphoma, important management considerations are addressed. We highlight need for follow up and role for surgery verse radiation. Finally, we present emerging treatment options and pre-clinical work that will be making its way through the pipeline. This up-to-date review will serve as a key learning tool for clinicians and researchers
原发性中枢神经系统淋巴瘤对临床医生提出了独特的挑战。关于适当的检查、管理考虑和治疗的新证据已经出现。在本文中,我们强调临床表现,疾病预后和管理注意事项。我们特别强调免疫功能正常和免疫功能低下的决策树。讨论了关键的成像特征。一旦活检证实淋巴瘤,重要的管理注意事项被解决。我们强调随访的必要性和手术与放疗的作用。最后,我们提出了新兴的治疗方案和临床前工作,将使其通过管道。这篇最新的综述将作为临床医生和研究人员的重要学习工具

Background:Congenital chylous ascites is a very rare condition that has been well recognized as early as the 1950s, and was mostly called “Congenital chyloperitoneum” during that time. Few cases have been reported during the 1960s, and in 1967, Craven et al attributed the development of congenital chylous ascites to obstruction of the cisterna chyli and chylous reflux into the peritoneal space and small intestine and they demonstrated lymphangiographically. Patients and methods: The use of a unique dietary therapy for the treatment of congenital chylous ascites is briefly described and the relevant literature is described. Results:An infant with congenital chylous ascites was seen at about the age of two and half months. He was initially treated with intravenous somatostatin infusion, and thereafter by repeated paracentesis, and continued to receive breast and bottle milk feedings. However, when he was first seen, ultrasound was still showing moderate ascites. The boy was successfully treated a combination of a unique form of very low-fat diet and octreotide acetate subcutaneous injections. Treatment was not associated with a negative effect on growth or development, and no evidence of nutritional deficiency was observed. Conclusion: The case number 112 of congenital chylous ascites is reported and its unique therapeutic approach is described.
背景:先天性乳糜腹水是一种非常罕见的疾病,早在20世纪50年代就已被广泛认识,在当时大多被称为“先天性乳腺炎”。在20世纪60年代,很少有病例报道,1967年,Craven等人将先天性乳糜腹水的发展归因于乳糜池阻塞和乳糜回流到腹膜间隙和小肠,并在淋巴管造影中证实了这一点。患者和方法:简要介绍一种独特的饮食疗法治疗先天性乳糜性腹水,并介绍相关文献。结果:一名婴儿在大约两个半月大时出现先天性乳糜腹水。他最初接受了静脉注射生长抑素的治疗,之后进行了反复的穿刺,并继续接受母乳和奶瓶喂养。然而,当他第一次被看到时,超声波仍然显示出中度腹水。这名男孩成功地接受了一种独特的低脂饮食和醋酸奥曲肽皮下注射相结合的治疗。治疗对生长发育没有负面影响,也没有观察到营养缺乏的证据。结论:报告112例先天性乳糜性腹水,并介绍其独特的治疗方法。
