Our previous studies have shown that Lycium barbarum(L. barbarum) polysaccharide(LBP) protects degenerated photoreceptors in rd1, a transgenic mouse model of retinitis pigmentosa. L. barbarum glycopeptide(Lb GP) is an immunoreactive glycoprotein extracted from LBP. In this study, we investigated the potential protective effect of Lb GP on a chemically induced photoreceptor-degenerative mouse model. Wild-type mice received the following: oral administration of Lb GP as a protective pre-treatment on days 1–7;intraperitoneal administration of 40 mg/kg N-methylN-nitrosourea to induce photoreceptor injury on day 7;and continuation of orally administered Lb GP on days 8–14. Treatment with Lb GP increased photoreceptor survival and improved the structure of photoreceptors, retinal photoresponse, and visual behaviors of mice with photoreceptor degeneration. Lb GP was also found to partially inhibit the activation of microglia in N-methyl-N-nitrosourea-injured retinas and significantly decreased the expression of two pro-inflammatory cytokines. In conclusion, Lb GP effectively slowed the rate of photoreceptor degeneration in N-methyl-N-nitrosourea-injured mice, possibly through an anti-inflammatory mechanism, and has potential as a candidate drug for the clinical treatment of photoreceptor degeneration.展开更多

However, evidence is accumulating that genetic background can contribute to urolithiasis formation. Advancements in the identification of monogenic causes using high-throughput sequencing technologies have shown that urolithiasis has a strong heritable component.Methods: This review describes monogenic factors implicated in a genetic predisposition to urolithiasis. Peer-reviewed journals were evaluated by a PubMed search until July 2023 to summarize disorders associated with monogenic traits, and discuss clinical implications of identification of patients genetically susceptible to urolithiasis formation.Results: Given that more than 80% of urolithiases cases are associated with calcium accumulation, studies have focused mainly on monogenetic contributors to hypercalciuric urolithiases, leading to the identification of receptors, channels, and transporters involved in the regulation of calcium renal tubular reabsorption. Nevertheless, available candidate genes and linkage methods have a low resolution for evaluation of the effects of genetic components versus those of environmental, dietary, and hormonal factors, and genotypes remain undetermined in the majority of urolithiasis formers.Conclusion: The pathophysiology underlying urolithiasis formation is complex and multifactorial, but evidence strongly suggests the existence of numerous monogenic causes of urolithiasis in humans.展开更多

This paper explores the impact of NeuroPhysics Treatment (NPT) on patients with HSP and FSHD. Through a series of clinical case reports, I demonstrate how intensive four-day NPT sessions can lead to rapid restoration of lost functions, challenging the conventional view of these disorders. I hypothesize that, by modulating the patient’s perceptual and behavioral frameworks, NPT facilitates the emergence of healthier patterns, suggesting that environmental and psychological factors significantly influence the manifestation and management of these conditions. These findings indicate that the role of genetic inheritance may be overstated and that beliefs and perceptions could play a crucial role in the evolution of psychophysical disorders. The implications of this research extend beyond the traditional treatment paradigms, advocating for a more holistic approach that integrates the psychophysical dimensions of health and challenges the deterministic perspective of genetic inheritance.展开更多

About 30% of sudden deaths is ascribable to genetically determined morbid entities, mostly transmissible with the autosomal dominant pattern of inheritance, so that 50% of the first degree relatives are genetically affected (“carriers”) and exposed at risk;4) If toxic or illicit drug abuse was involved.展开更多

文摘BACKGROUND Hypoparathyroidism(HP)is a rare endocrine disorder,while situs inversus totalis(SIT)is a rare condition in which the internal organs are positioned in a mirrored pattern compared to their usual positions.This case illustrates some potential shared mechanisms between HP and SIT,highlighting the importance of accurate identification and prompt first emergency,offering insights for future research.CASE SUMMARY This report discusses a case of a middle-aged patient with adolescent-onset HP with concurrent SIT.The patient experienced recurrent episodes of increased neuromuscular excitability(manifesting as spasms in the hands and feet and laryngospasms)and even periods of unconsciousness.Initially,these symptoms led to a misdiagnosis of epilepsy.Nevertheless,upon thorough examination and treatment in the general medicine ward,the correct diagnosis was established.Corresponding treatment resulted in improved management of the patient’s symptoms.CONCLUSION Co-occurrence of HP and SIT may be associated with genetic mutations,chromosomal anomalies,or hereditary factors,as may other similar conditions.
文摘Intangible cultural heritage is an important part of human civilization,and its protection and inheritance are of great significance for maintaining the diversity of national culture and the continuity of traditional culture.In order to better protect intangible cultural heritage,many countries have formulated corresponding protection standards and policies.This paper summarizes and studies the current standardization development of intangible cultural heritage protection in various countries,explores its significance,current situation,and development trends,and provides suggestions for the standardization of intangible cultural heritage protection in China.
文摘In accounts of the development and progression of psychophysical disorders such as Hereditary Spastic Paraplegia (HSP) and Facioscapulohumeral Muscular Dystrophy (FSHD), the role of beliefs, perceptions, and behavioral patterns has often been overlooked in favor of a genetically determinist paradigm. This paper explores the impact of NeuroPhysics Treatment (NPT) on patients with HSP and FSHD. Through a series of clinical case reports, I demonstrate how intensive four-day NPT sessions can lead to rapid restoration of lost functions, challenging the conventional view of these disorders. I hypothesize that, by modulating the patient’s perceptual and behavioral frameworks, NPT facilitates the emergence of healthier patterns, suggesting that environmental and psychological factors significantly influence the manifestation and management of these conditions. These findings indicate that the role of genetic inheritance may be overstated and that beliefs and perceptions could play a crucial role in the evolution of psychophysical disorders. The implications of this research extend beyond the traditional treatment paradigms, advocating for a more holistic approach that integrates the psychophysical dimensions of health and challenges the deterministic perspective of genetic inheritance.
文摘The role of the autopsy: 1) Whether the death is ascribable to a natural or unnatural cause and when natural, if cardiac or extra-cardiac;2) The nosology of the cardiac diseases and the mechanism of cardiac death, whether arrhythmic or mechanical;3) If the cardiac disease is inherited, screening and counselling of the next of kin is required. About 30% of sudden deaths is ascribable to genetically determined morbid entities, mostly transmissible with the autosomal dominant pattern of inheritance, so that 50% of the first degree relatives are genetically affected (“carriers”) and exposed at risk;4) If toxic or illicit drug abuse was involved.

文摘BACKGROUND Genetic factors play an important role in neonatal hyperbilirubinemia(NH)caused by genetic diseases.AIM To explore the characteristics of genetic mutations associated with NH and analyze the correlation with genetic diseases.METHODS This was a retrospective cohort study.One hundred and five newborn patients diagnosed with NH caused by genetic diseases were enrolled in this study between September 2020 and June 2023 at the Second Affiliated Hospital of Xiamen Medical College.A 24-gene panel was used for gene sequencing to analyze gene mutations in patients.The data were analyzed via Statistical Package for the Social Sciences 20.0 software.RESULTS Seventeen frequently mutated genes were found in the 105 patients.Uridine 5'-diphospho-glucuronosyltransferase 1A1(UGT1A1)variants were identified among the 68 cases of neonatal Gilbert syndrome.In patients with sodium taurocholate cotransporting polypeptide deficiency,the primary mutation identified was Na+/taurocholate cotransporting polypeptide Ntcp(SLC10A1).Adenosine triphosphatase 7B(ATP7B)mutations primarily occur in patients with hepatolenticular degeneration(Wilson's disease).In addition,we found that UGT1A1 and glucose-6-phosphate dehydrogenase mutations were more common in the high-risk group than in the low-risk group,whereas mutations in SLC10A1,ATP7B,and heterozygous 851del4 mutation were more common in the low-risk group.CONCLUSION Genetic mutations are associated with NH and significantly increase the risk of disease in affected newborns.
文摘The physical mechanism of heredity or inheritance of genes is a quantum mechanical and/or quantum computational process. A theory of bio-quantum genetics is established in this paper. Principle of Bio-quantum Genetics is suggested. I propose and define the soft-genes of genetics controlling the processes of heredity or inheritance of genes. This research deals with the quantum mechanisms of Mendel plant heredity and family inheritance as examples of bio-quantum genetics, deepening our understanding of heredity or inheritance. I believe that more contributions will be made to promote researches of bio-quantum genetics or quantum biology at large.
