Atherosclerosis in elderly patients may be the leading cause of ISR. Therefore, we aim to explore the relationship between vascular calcification-associated factors and ISR occurrence. Elderly patients were enrolled according to standard inclusion and exclusion criteria. The serum fibroblast growth factor 23 (FGF23), hypoxia-inducible factor-1α (HIF-1α), and Klotho levels were determined using an enzyme-linked immunosorbent assay. The degree of coronary artery stenosis of the patients with CAD before operation was assessed using the Gensini score. The correlation was analyzed using Pearson analysis. The prediction value was evaluated using receiver operating characteristic (ROC) curve analysis. The patients with CAD were classified into the ISR group with 97 cases and the non-ISR (NISR) group with 349 cases. The Gensini score, serum FGF23, and HIF-1α levels increased while Klotho levels decreased in patients with CAD of the ISR group compared with those of the NISR group. Pearson analysis showed that FGF23 and HIF-1α positively correlated while Klotho negatively correlated to the Gensini score. ROC analysis showed all three factors could effectively predict the occurrence of ISR. Furthermore, the joint had a more effective prediction value for ISR occurrence. The dynamic analysis presented that the serum FGF23 and HIF-1α levels dramatically increased while Klotho levels decreased in patients with CAD after 1-year follow-up. Serum FGF23 and HIF-1α positively correlated while serum Klotho negatively correlated to ISR. Conclusively, these three factors effectively predicted the occurrence of ISR.</p>","PeriodicalId":94189,"journal":{"name":"Rejuvenation research","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142635251","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study aimed to determine whether predictive nursing, guided by risk assessment, could reduce these risks and improve patient outcomes. A total of 191 elderly patients undergoing total hip arthroplasty were included in the study, with 142 patients randomly assigned to either the control or observation groups. The control group received routine care, while the observation group received predictive nursing based on comprehensive risk assessment. Various assessment tools were employed to evaluate risks such as venous thrombosis, pressure injuries, falls, joint dislocation, infections, and psychological factors. The primary outcomes included functional improvement measured by the Harris Hip Score, Activities of Daily Living (ADL), anxiety levels, and patient satisfaction. Our study demonstrated that predictive nursing interventions, guided by comprehensive risk assessment, yielded significant reductions in postoperative complications, particularly deep vein thrombosis, in elderly patients undergoing total hip arthroplasty. In addition, patients who received predictive nursing care experienced notable benefits, including shorter hospital stays, heightened satisfaction levels, enhanced hip function, improved ADL scores, and reduced anxiety levels compared with those receiving standard care. The study underscores the substantial benefits of predictive nursing interventions guided by risk assessment in improving outcomes for elderly patients undergoing total hip arthroplasty, highlighting the potential of individualized nursing care to optimize postoperative recovery and enhance patient well-being.</p>","PeriodicalId":94189,"journal":{"name":"Rejuvenation research","volume":" ","pages":""},"PeriodicalIF":0.0,"publicationDate":"2024-11-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142635247","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The potential mechanism of ginseng in the context of HF was investigated using systems pharmacology that combined network pharmacology, Gene Expression Omnibus (GEO) analysis, molecular docking, and experimental verification. Network pharmacology was employed to identify drug-disease targets. Core gene targets were subsequently subjected to enrichment analysis by integrating network pharmacology with GEO. Molecular docking was utilized to predict the binding affinities between identified targets and ginseng compounds. Furthermore, the therapeutic efficacy of ginseng was validated in an isoproterenol (ISO)-induced rat model of HF. The modulation of key signaling pathways by ginseng was confirmed through Western blot analysis. A total of 154 potential targets of ginseng in the treatment of HF were identified through network pharmacology analysis. The analysis of GSE71613 revealed that the PI3K-Akt pathway, reactive oxygen species, oxidative phosphorylation, MAPK signaling, and Ras signaling pathways are predominantly associated with patients with HF. By integrating the findings from network pharmacology and GEO analysis, ginsenoside Rg1 and ginsenoside Rb3 were identified as the potential components in ginseng, while <i>FN1</i> and <i>PRKAA2</i> were recognized as key targets involved in the PI3K-AKT and AMPK pathways, respectively. Molecular docking analysis revealed a strong affinity between the potential components and the identified core targets. <i>In vivo</i> experiments indicated that the extract of ginseng (EPG) significantly ameliorated ISO-induced cardiac dysfunction by improving cardiac parameters such as cardiac left ventricular internal systolic diameter, left ventricular end-diastolic volume, left ventricular end systolic volume, and left ventricular ejection fraction, while also reducing malondialdehyde production. In addition, EPG was found to enhance superoxide dismutase activity and ATP levels, while concurrently reducing the levels of interleukin (IL)-1β, IL-6, and TNF-α. The extract also reduced myocardial oxygen consumption, inflammatory cell infiltration, and the number of damaged myocardial fibers. Moreover, EPG was observed to upregulate the expression of p-PI3K, p-AKT, p-AMPK, and Bcl-2, while downregulating the expression of p-NFκB, TGF-β, and Bax. The therapeutic effects of ginseng on HF are primarily mediated through the PI3K-Akt and AMPK pathways.

Thirty Sprague Dawley rats were randomly divided into three groups, including a control group, an RA model group, and a moxibustion group. An RA model was created through the injection of Freund's complete adjuvant. In the moxibustion group, rats were treated with moxibustion at acupoints of \"Shenshu\" and \"Zusanli.\" A total of three courses of treatment were conducted. Then the thickness of foot pad was measured, joint pathological changes were observed by hematoxylin-eosin (HE) staining, the proportion of CD4⁺T and CD8⁺T in peripheral blood was detected by flow cytometry, the expression levels of Tim-3 and Gal-9 in synovium were detected by polymerase chain reaction (PCR), and the expressions of CD4⁺T and CD8⁺T in synovium were detected by immunofluorescence. HE staining showed that the synovial tissue of the control group was smooth and neatly arranged without inflammatory cell infiltration. In the model group, the joint space was narrowed, the synovial tissue had congestion and edema, and a large number of inflammatory cells infiltrated. Compared with the model group, in the moxibustion group, the joint space narrowed with synovium hyperemia and edema, and the level of inflammatory cell infiltration decreased. Flow cytometry showed that compared with the model group, CD4⁺T expression in the moxibustion group was downregulated, while CD8⁺T expression was upregulated. PCR results showed that compared with the model group, the expressions of Tim-3 and Gal-9 in the moxibustion group were upregulated. Immunofluorescence results showed that compared with the model group, CD4⁺T expression in the moxibustion group was decreased, while CD8⁺T expression was increased. The results demonstrate that moxibustion not only suppressed the expression of CD4⁺T but also promoted the expression of CD8⁺T.

Oxidative stress has been linked to several symptoms, including hyperglycemia, reactive oxygen species buildup, high blood pressure, and the expression of inflammatory markers. Therefore, the present research aimed to evaluate the genetic abnormality of NQO1 (rs1800566, C609T) gene polymorphism, expression, and vitamin-D level assessment among Type 2 diabetes mellitus (T2DM) patients. The study included 100 newly diagnosed T2DM cases and 100 healthy individuals as healthy controls. Total RNA was extracted from the whole blood using the TRIzol method, and further cDNA was synthesized, and expression was evaluated. There is a significant difference in NQO1 (rs1800566, C609T) genotype distribution among the T2DM patients and healthy controls (<i>p</i> = 0.04). Compared with the NQO1 CC wild-type genotype, the NQO1 CT heterozygous genotype had an odds ratio of 1.96 (1.08-3.55), and the NQO1 TT mutant type genotype had an odds ratio of 3.31 (0.61-17.77). Significantly decreased expression of NQO1 mRNA was observed with heterozygous CT (<i>p</i> < 0.0001) and homozygous mutant TT genotype (<i>p</i> = 0.0004), compared with homozygous wild-type CC genotype. NQO1 mRNA expression level was also compared with vitamin D levels among the T2DM patients. T2DM patients with vitamin D deficiency had 1.83-fold NQO1 mRNA expression, while vitamin D insufficient and sufficient T2DM cases had 3.31-fold (<i>p</i> < 0.0001) and 3.70-fold (<i>p</i> < 0.0001) NQO1 mRNA expression. It was concluded that NQO1 (rs1800566, C609T) CT and TT genotypes played a significant role in the worseness of type II diabetes mellitus, and decreased expression of NQO1 mRNA expression could be an essential factor for disease worseness as well as hypermethylation could be a factor for reduced expression leading to disease severity.
