The armadillo repeat containing 5 (ARMC5) gene is part of a family of protein-coding genes that are rich in armadillo repeat sequences, are ubiquitously present in eukaryotes, and mediate interactions between proteins, playing roles in various cellular processes. Current research has demonstrated that reduced expression or absence of the ARMC5 gene in various tumor tissues can lead to uncontrolled cell proliferation, thereby inducing a range of diseases. The ARMC5 gene was initially extensively studied in the context of bilateral macronodular adrenocortical disease (BMAD), with harmful pathogenic variants in ARMC5 identified in approximately 50% of BMAD patients. With advancing research, scientists have discovered that ARMC5 pathogenic variants may also have potential effects on other diseases and could be associated with increased susceptibility to certain cancers. This review aims to present the latest research progress on how the ARMC5 gene plays its role in tumors. It outlines the basic structure of ARMC5 and the regions where it functions, as well as the diseases currently proven to be associated with ARMC5. Moreover, some evidence suggests its relation to embryonic development and the regulation of immune system activity. In conclusion, the ARMC5 gene is a crucial focal point in genetic and medical research. Understanding its function and regulation is of great importance for the development of new therapeutic strategies related to diseases associated with its pathogenic variants.

From the natural-philosophical model of medicine in ancient Greece to the modern bio-psycho-social par-adigm,the evolution of medical models has always been shaped by philosophy.In classical antiquity,medicine and philosophy were closely intertwined;the natural-philosophical model,exemplified by Hippocrates,emphasized the human body as an integrated whole.During the Renaissance,the rise of experimental science challenged traditional philosophical systems and pushed medicine toward empirical investigation.In the late twentieth century,the bio-psycho-social model emerged to address the limitations of the purely biomedical approach.In the twenty-first centu-ry,the advent of artificial intelligence is driving a new transformation in medicine and continually prompting reflec-tion on the future direction of medical models and their underlying philosophical significance.

Objective To observe the clinical efficacy of Ginkgo Diterpene Lactone Meglumine Injection combined with alteplase(rt-PA)in the treatment of acute ischemic stroke with large vessel occlusion.Methods A total of 170 patients with acute ischemic stroke with large vessel occlusion were selected as the study subjects and randomly divided into control group(receiving intravenous rt-PA thrombolytic therapy)and observation group(receiving Ginkgo Diterpene Lactone Meglumine In-jection in addition to the treatment in the control group),with 85 cases in each group.Serological in-dicators[neuron-specific enolase(NSE),vascular endothelial growth factor(VEGF),homocysteine(Hcy),high-sensitivity C-reactive protein(hs-CRP),matrix metalloproteinase-9(MMP-9)],cere-bral blood flow velocity in the middle cerebral artery[end-diastolic velocity(EDV),peak systolic ve-locity(PSV),mean velocity(Vm)],neurological function[National Institutes of Health Stroke Scale(NIHSS)score],cognitive function[Mini-mental State Examination(MMSE)score],modi-fied Rankin Scale(mRS)score,and the incidence of complications were compared between the two groups.Results After treatment,the serum levels of NSE,Hcy,hs-CRP,MMP-9,and the NIHSS and mRS scores in both groups were lower than those before treatment,while the serum level of VEGF and the MMSE score were higher than those before treatment(P＜0.05).Moreover,the serum lev-els of NSE,Hcy,hs-CRP,MMP-9,and the NIHSS and mRS scores in the observation group were lower than those in the control group,and the serum level of VEGF and the MMSE score were higher than those in the control group,with statistically significant differences(P＜0.05).After treat-ment,the EDV,PSV and Vm in both groups were higher than those before treatment,and those in the observation group were higher than those in the control group,with statistically significant differ-ences(P＜0.05).There was no statistically significant difference in the overall incidence of com-plications between the two groups(P＞0.05).Conclusion Ginkgo Diterpene Lactone Meglumine Injection combined with rt-PA can effectively improve the neurological and cognitive functions of a-cute ischemic stroke patients with large vessel occlusion.

The monitoring of the construction indexes of NRMCs could provide a basis and support for hospitals to identify problems in time, seek government support, and carry out target management, and has reference for promoting the effective construction of NRMCs.

OBJECTIVE To investigate the improvement effects of Arisaema Cum Bile on Parkinson’s disease （PD） model mice and its potential mechanism. METHODS Sixty male C57BL/6J mice were randomly divided into normal group， model group， Arisaema Cum Bile low-dose group [0.39 g/（kg·d）]， Arisaema Cum Bile high-dose group [1.56 g/（kg·d）] and positive control drug Levodopa tablet group [80 mg/（kg·d）]， with 12 mice in each group. Except that normal group was given constant volume of normal saline， other groups were given 1-methyl-4-phenyl-1，2，3，6-tetrahydropyridine [MPTP，35 mg/（kg·d）] intraperitoneally for 5 consecutive days to induce subacute PD model； after modeling， they were given relevant medicine continuously for 7 d； rod climbing test and line suspension test were performed 1 d before modeling， on the 5th day of modeling and after the last medication. The number of tyrosine hydroxylase （TH）-positive neurons in the substantia nigra of mice were measured by immunofluorescence； the levels of interleukin 1β （IL-1β） and tumor necrosis factor α（ TNF-α） in serum and the levels of IL- E-mail：qhwang668@sina.com 1β， TNF-α， cyclooxygenase-2 （COX-2） and inducible nitric oxide synthase （iNOS） in the substantia nigra of mice were measured by enzyme-linked immunosorbent assay. The expression levels of cAMP-dependent protein kinase catalytic subunit α （PKA C-α）， glutathione peroxidase 4 （GPX4） and ferritin heavy chain polypeptide 1 （FTH1） proteins in the substantia nigra of mice was measured by Western blot. RESULTS After last medicine， compared with the normal group， mice in the model group had significantly longer pole-climbing time （P＜0.01）， significantly lower line suspension scores （P＜0.01）， significantly fewer TH-positive neurons in the substantia nigra （P＜0.01）， significantly higher serum concentrations of IL-1β and TNF-α and nigrostriatal concentrations of IL-1β， TNF-α， COX-2 and iNOS （P＜0.01）， while lower protein expression levels of GPX4， PKA C-α and FTH1 in the substantia nigra （P＜0.05 or P＜0.01）. Compared with the model group， the above indexes of mice were significantly returned in Arisaema Cum Bile high-dose group （P＜0.05 or P＜ 0.01）. CONCLUSIONS Arisaema Cum Bile can improve motor impairment and reduce apoptosis of nigrostriatal TH neurons in MPTP-induced PD mice， and has neuroprotective effects on model mice； this may be related to its inhibition of neuroinflammation and the inhibition of ferroptosis by up-regulating PKA signaling pathway.
