RESUMEN

BACKGROUND: As the global population ages, we witness a broad scientific and technological revolution tailored to meet the health challenges of older adults. Over the past 25 years, technological innovations, ranging from advanced medical devices to user-friendly mobile apps, are transforming the way we address these challenges, offering new avenues to enhance the quality of life and well-being of the aging demographic. OBJECTIVE: This study aimed to systematically review the development trends in technology for managing and caring for the health of older adults over the past 25 years and to project future development prospects. METHODS: We conducted a comprehensive bibliometric analysis of literatures related to technology-based solutions for health challenges in aging, published up to March 18, 2024. The search was performed using the Web of Science Core Collection, covering a span from 1999 to 2024. Our search strategy was designed to capture a broad spectrum of terms associated with aging, health challenges specific to older adults, and technological interventions. RESULTS: A total of 1133 publications were found in the Web of Science Core Collection. The publication trend over these 25 years showed a gradual but fluctuating increase. The United States was the most productive country and participated in international collaboration most frequently. The predominant keywords identified through this analysis included "dementia," "telemedicine," "older-adults," "telehealth," and "care." The keywords with citation bursts included "telemedicine" and "digital health." CONCLUSIONS: The scientific and technological revolution has significantly improved older adult health management, particularly in chronic disease monitoring, mobility, and social connectivity. The momentum for innovation continues to build, with future research likely to focus on predictive analytics and personalized health care solutions, further enhancing older adults' independence and quality of life.

RESUMEN

BACKGROUND: Chinese patent medicines Compound Danshen Dripping Pills (DSP) and Di'ao Xinxuekang (DXK) capsules were both found effective in treating angina pectoris. However, there is no systematic review comparing their efficacy. OBJECTIVE: This systematic review aims to compare the efficacy of DSP and DXK in treating angina pectoris based on randomized controlled trials (RCTs) comparing their efficacy. SEARCH STRATEGY: RCT reports published between 1994 and 2011 were retrieved from databases including China Doctoral Dissertations Full-text Database, Chinese Journal Full-text Database, China Master's Theses Full-text Database, Wanfang Data, Cochrane Library, Excerpts Medica Database, ScienceDirect, MEDLINE (EBSCOhost) and PubMed. The last retrieval was performed on April 7, 2011. INCLUSION CRITERIA: RCT reports comparing the effects of DSP and DXK were included, regardless publishing language. DATA EXTRACTION AND ANALYSIS: Included RCT reports were assessed for their study quality by using the Jadad scale and the Cochrane risk of bias tool. Data including overall effect and electrocardiography (ECG) improvements were extracted from the included RCTs for meta-analysis. The effect sizes based on overall and ECG diagnosis were measured by odds ratio (OR) and 95% confidence interval (CI). Subgroup analysis and sensitivity analysis were also performed. RESULTS: Nine RCT reports with 926 participants were included. Eight were scored 2 and the other one was scored 4 by using the Jadad scale. The OR between DSP and DXK based on overall diagnosis was 2.06 (95% CI: 1.03-4.12; P(overall)=0.04). Six out of the nine included RCTs reported ECG data. The OR between DSP and DXK based on the ECG diagnosis was 1.92 (95% CI: 1.23-3.00; P(ECG)=0.004). The OR results were stable under subgroup analysis and sensitivity analysis. CONCLUSION: DSP was consistently more effective than DXK according to meta-analysis, which was verified by subgroup analysis and sensitivity analysis. However, more RCTs of higher quality are needed for further confirmation.

RESUMEN

Nowadays, the physicians usually predict functional outcomes of stroke based on clinical experiences and big data, so we wish to develop a model to accurately identify imaging features for predicting functional outcomes of stroke patients. Using magnetic resonance imaging of ischemic and hemorrhagic stroke patients, we developed and trained a VGG-16 convolutional neural network (CNN) to predict functional outcomes after 28-day hospitalization. A total of 44 individuals (24 men and 20 women) were recruited from Taoyuan General Hospital and China Medical University Hsinchu Hospital to enroll in the study. Based on "modified Rankin Scale (mRS)" and "National Institutes of Health Stroke Scale (NIHSS)" assessments, men, women, and mixed men and women were trained separately to evaluate the differences of the results, and we have shown that VGG-16 demonstrated high accuracy in predicting the functional outcomes of stroke patients. The new deep-learning approach has provided an automated decision support system for personalized recommendations and treatments, assisting the physicians to predict functional outcomes of stroke patients in clinical practice.

RESUMEN

Previous studies have suggested that microsomal prostaglandin E synthase-1 (mPGES-1) is highly expressed and closely associated with mitogen-activated protein kinase (MAPK) signaling pathways in various types of malignant cells. However, their expression patterns and function with respect to T-cell acute lymphoblastic leukemia (T-ALL) remain largely unknown. The present study investigated whether mPGES-1 served a crucial role in T-ALL and aimed to identify interactions between mPGES-1 and the MAPK signaling pathway in T-ALL. The results indicated that mPGES-1 overexpression in T-ALL jurkat cells was significantly decreased by RNA silencing. Decreasing mPGES-1 on a consistent basis may inhibit cell proliferation, induce apoptosis and arrest the cell cycle in T-ALL jurkat cells. Microarray and western blot analyses revealed that c-Jun N-terminal kinase served a role in the mPGES-1/prostaglandin E2/EP4/MAPK positive feedback loops. In addition, P38 and extracellular signal-regulated kinase 1/2 exhibited negative feedback effects on mPGES-1. In conclusion, the results suggested that cross-talk between mPGES-1 and the MAPK signaling pathway was very complex. Therefore, the combined regulation of mPGES-1 and the MAPK signaling pathway may be developed into a new candidate therapy for T-ALL in the future.

RESUMEN

OBJECTIVE: To investigate the effects of shRNA targeting mPGES-1 on tumorigenicity of human acute leukemia K562 cells in nude mice in vivo and its mechanisms. METHODS: For experiment 3 groups including KD group(expression of mPGES-1 in K562 cells was down-regulated by shRNA), CON (cells without any treatment) and NC group (cells treated with nonspecific-sequence shRNA) were set-up. Western blot was used to test the expression of ß-catenin and cyclinD1 in cells. Then the cells of 3 groups were implanted into BALB/c nude mice subcutaneously to establish murine xenograft model. The growth state of the mice and the size of the xenograft tumor were recorded. HE staining was used to observe the morphology of xenograft tumor. Expressions of ß-catenin and cyclinD1 in xenograft tumor were detected by immunohistochemical staining. RESULTS: In vitro the expression of ß-catenin and cyclinD1 in KD group were lower than the CON group and NC group (P<0.05). In vivo the tumor volume and weight of KD group were significant smaller than the other two groups (P<0.01). HE staining showed that tissues in the KD group were relatively looser in arrangement with smaller cell nucleus and less cytoplasm. The expression of ß-catenin and cyclinD1 in the KD group were remarkable weak as compared with that in CON group and NC group (P<0.05). CONCLUSION: Down-regulating the expression of mPGES-1 by shRNA may significantly inhibit the tumorigenicity of K562 cells in nude mice in vivo and its mechanism may be related with the inhibition of expression of ß-catenin and cyclinD1.

RESUMEN

OBJECTIVE: To explore the role of Treg cells in the pathogenesis of idiopathic thrombocytopenic purpura (ITP). METHODS: The ITP mouse model was established, the Treg cell ratio in peripheral blood and spleen was detected by flow cytometry, the CD4+ CD25+ T cells were sorted by immunomagnetic beads, the Treg cell associated transcription factors (Foxp3, Smad7, STAT5 and Akt-1) and cytokines (IL-10, TGF-ß) in CD4+ CD25+ T cells were enriched from spleen mononuclear cells, and the mRNA expression of Treg cell was measured by real-time PCR. RESULTS: The ratio of Tregs in peripheral blood and spleen decreased significantly in ITP mouse, as compared with the controls (P<0.01). In addition, the mRNA expression of IL-10, TGF-ß and Foxp3 decreased significantly in spleen CD4+ CD25+ T cells (P<0.05). Expression of Smad 7 mRNA was higher than that of controls. CONCLUSION: The alteration in Treg frequency and function may be responsible for the immune dysfunction in ITP disease. It is also speculated that the lower mRNA expression of Foxp3 and higher mRNA expression of Smad 7 may inhibit the proliferation and differentiation of Treg cells.

RESUMEN

OBJECTIVE: To investigate the platelet activity and function in pregnancy induced hypertension (PIH) and gestational diabetes mellitus (GDM). METHODS: Twenty-one patients with GDM and 23 patients with PIH in third-trimester were included. Twenty normal pregnant women in third-trimester served as controls. Platelet count (PC), mean platelet volume (MPV) were determined on Cell-DYN 1600 and the expression of CD62P was analyzed on FACSC alibur. RESULTS: (1) PC was (181 +/- 56) x 10(9)/L in PIH, (206 +/- 60) x 10(9)/L in GDM and (229 +/- 56) x 10(9)/L in controls, respectively. PC in PIH was lower than that of controls (P < 0.01), but there was no significant difference between GDM and controls. (2) MPV was (11.2 +/- 2.0) fl in PIH, significantly higher than that of controls (8.7 +/- 1.6) fl (P < 0.001). In GDM, MPV was (9.5 +/- 1.6) fl, without significant difference compared with that of controls. (3) The expression of CD62P increased significantly in PIH compared with controls [CD62P: (42 +/- 13)% vs (26 +/- 7)%, P < 0.001; CD62P(I): 109 +/- 39 vs 75 +/- 13, P < 0.01]. In GDM, the expression of CD62P also increased significantly compared with the normal pregnancy [CD62P(%): (42 +/- 14)% vs (26 +/- 7), P < 0.001; CD62P(I): 100 +/- 42 vs 75 +/- 13, P < 0.05]. (4) All parameters had no significant difference between PIH and GDM. CONCLUSION: Platelet activity is enhanced in PIH and GDM. It may play an important role in the pathogenesis and development of the two diseases.

RESUMEN

AIM: To study the effects of hypoxia-inducible factor-1α (HIF-1α) silencing on the proliferation of hypoxic CBRH-7919 rat hepatoma cells. METHODS: The CBRH-7919 rat hepatoma cell line was used in this study and the hypoxic model was constructed using CoCl2. The HIF-1α-specific RNAi sequences were designed according to the gene coding sequence of rat HIF-1α obtained from GeneBank. The secondary structure of the HIF-1α gene sequence was analyzed using RNA draw software. The small interfering RNA (siRNA) transfection mixture was produced by mixing the siRNA and Lipofectamine2000(TM), and transfected into the hypoxic hepatoma cells. Real time reverse transcription-polymerase chain reaction (RT-PCR) and Western blotting assay were used to detect the expression levels of mRNA and protein. HIF-1α and vascular endothelial growth factor (VEGF) mRNA was determined using real time RT-PCR; the protein expression levels of AKT, p-AKT, p21 and cyclinD1 were determined using Western blotting. The proliferation of hepatoma cells was observed using the methyl thiazolyl tetrazolium (MTT) assay and the bromodeoxyuridine (BrdU) incorporation cell proliferation assay. RESULTS: Under induced hypoxia, the viability of the hepatoma cells reached a minimum at 800 µmol/L CoCl2; the viability of the cells was relatively high at CoCl2 concentrations between 100 µmol/L and 200 µmol/L. Under hypoxia, the mRNA and protein expression levels of HIF-1α and VEGF were significantly higher than that of hepatoma cells that were cultured in normaxia. HIF-1α-specific RNAi sequences were successfully transfected into hepatoma cells. The transfection of specific siRNAs significantly inhibited the mRNA and protein expression levels of HIF-1α and VEGF, along with the protein expression levels of p-AKT and cyclinD1; the protein expression of p21 was significantly increased, and there was no significant difference in the expression of AKT. The MTT assay showed that the amount of hepatoma cells in S phase in the siRNA transfection group was obviously smaller than that in the control group; in the siRNA transfection group, the amount of hepatoma cells in G1 phase was more than that in the control group. The BrdU incorporation assay showed that the number of BrdU positive hepatoma cells in the siRNA transfection group was less than that in the control group. The data of the MTT assay and BrdU incorporation assay suggested that HIF-1α silencing using siRNAs significantly inhibited the proliferation of hepatoma cells. CONCLUSION: Hypoxia increases the expression of HIF-1α, and HIF-1α silencing significantly inhibits the proliferation of hypoxic CBRH-7919 rat hepatoma cells.

RESUMEN

To investigate the effect of a microsomal prostaglandin E synthase-1 (mPGES-1) inhibitor MK886 on cell cycle of the human acute myeloid leukemia HL-60 cells. HL-60 cells were treated with different concentration of MK886 (10, 25, 50 µmol/L) for 24 h. Flow cytometry, Western blot and ELISA were used to measure cell cycle, cyclin D1, mPGES-1, PGE(2), Akt, P-Akt and C-MYC. The results indicated that after treated with MK886, the percentage of HL-60 cells decreased in G(0)/G(1) phase and increased in S phase, and expressions of mPGES-1, cyclin D1, P-Akt and C-MYC and synthesis of PGE(2) decreased significantly. It is concluded that MK886 can arrest HL-60 cells in G(0)/G(1) phase, the mechanism of which is possibly associated to inhibition of mPGES-1 expression, reduction of PGE(2) synthesis, suppression of Akt phosphorylation and C-MYC expression, down-regulation of cyclin D1 expression.

RESUMEN

This study was aimed to investigate the effect of MK886, a mPGES-1 inhibitor, on apoptosis and drug resistance of leukemia HL-60/A cell line. Expression of mPGES-1 was assayed by QT-PCR and Western blot. The effect of MK886 on HL-60/A cell proliferation was assayed by CCK-8 method, and flow cytometry was used to detect cell apoptosis. The expression of Akt and P-Akt was detected by Western blot. PGE2 was measured by ELISA. Effect of MK886 (10 µmol/L) on the chemotherapeutic sensitivity of HL-60/A cells and expression of mdr-1 mRNA and P170 protein were investigated too. The results indicated the expression of mPGES-1 was higher in HL-60/A cells. MK886 inhibited HL-60/A cell proliferation and induced apoptosis in a time- and concentration-dependent manner. Expression of mPGES-1 and P-Akt and synthesis of PGE2 decreased significantly. MK886 reduced expression of mdr-1 and P170 protein and enhanced the sensitivity of HL-60/A cells to chemotherapeutic drugs. It is concluded that MK886 can inhibit HL-60/A cell proliferation, induce apoptosis and enhance sensitivity to chemotherapeutic drugs, the mechanism of which possibly associates to down-regulation of mPGES-1/PGE2 synthesis, reduction P-Akt expression and decreasing mdr-1 and P170 protein expression.
