RESUMEN

BACKGROUND: This study aimed to assess family function in home care for older adults. Understanding family dynamics is essential for providing quality care to older adults choosing to age in place. METHODS: In a cross-sectional study, 53 patients aged 65 or older receiving home care were evaluated, along with four home care nurses. The General Function of Family Assessment Device (FAD-GF) was used for self-assessment to examine family resources. RESULTS: Only 5.7% of older adults reported good family function. Strong correlations were found between assessments by nurses and older adults. Among the six aspects of family function, "problem solving," "communication," "affective responsiveness," and the overall results showed no disparities between the evaluations of older adults and nurses. CONCLUSIONS: Home care nurses can effectively assess family function using the FAD-GF, particularly after six months of care. This assessment can help identify family issues and enhance home care quality through nurse training in FAD-GF application.

RESUMEN

Two new rare trachylobane euphoratones A-B (1-2), together with five known diterpenoids (compounds 3-7), were isolated from the aerial parts of Euphorbia atoto. Their structures were unambiguously elucidated through HRESIMS, 1D and 2D NMR spectral analysis. Compounds 1, 3, 4 and 7 showed weak anti-inflammatory activities (IC50 77.49 ± 6.34, 41.61 ± 14.49, 16.00 ± 1.71 and 33.41 ± 4.52 µM, respectively), compared to the positive control quercetin (IC50 15.23 ± 0.65 µM).

RESUMEN

To reduce the mortality and morbidity associated with cancer, new cancer theranostics are in high demand and are an emerging area of research. To achieve this goal, we report the synthesis and characterization of piperazine-linked 1,8-naphthalimide-arylsulfonyl derivatives (SA1-SA7). These compounds were synthesized in good yields following a two-step protocol and characterized using multiple analytical techniques. In vitro cytotoxicity and fluorescent cellular imaging of the compounds were assessed against non-cancerous fibroblast (3T3) and breast cancer (4T1) cell lines. Although the former study indicated the safe nature of the compounds (viability = 82-95% at 1 µg/mL), imaging studies revealed that the designed probes had good membrane permeability and could disperse in the whole cell cytoplasm. In silico studies, including molecular docking, molecular dynamics (MD) simulation, and ADME/Tox results, indicated that the compounds had the ability to target CAIX-expressing cancers. These findings suggest that piperazine-linked 1,8-naphthalimide-arylsulfonyl derivatives are potential candidates for cancer theranostics and a valuable backbone for future research.

RESUMEN

BACKGROUND & PROBLEMS: Patients with liver transplantation must take lifelong immunosuppressant medication to maintain the function of their hepatic graft. Based on clinical experience, we found that these patients were affected by both insufficient and remaining medication when they returned for outpatient service visits. After investigating the current situation, It was found that post-transplantation perceptions regarding medication were low in this patient group. After analysis, the identified causes of this included: (1) poor learning effect due to the interference from the multiple therapeutic catheter placement postoperatively; (2) delayed timing of assessing the awareness of information or perception of medication and lack of a post-operative follow-up mechanism; and (3) insufficient educational tools and materials for patients. PURPOSE: This study was designed to increase medication awareness from the current average of 68.3% to >91% and to increase patient satisfaction with medication guidance from the current 63.0% to >85% in patients who had received liver transplantation. RESOLUTIONS: The improvement strategy included: designing a health education sheet including related medication information and a daily medication record; designing a mnemonic, interactive video, or test to improve medication perception; creating measures associated with a monitor mechanism to assess medication knowledge. RESULTS: After strategy implementation, medication awareness increased from 68.3% to 92.5% and satisfaction with medication guidance increased from 63.0% to 87.2%. CONCLUSIONS: The implementation of several strategies concurrently can enhance medication awareness in patients after liver transplantation and increase patient satisfaction with medication guidance.

RESUMEN

Rheumatoid arthritis(RA), as a chronic autoimmune disease, has a high incidence and disability rate, causing significant suffering to patients. Due to its complex pathogenesis, it has not been fully elucidated to date, and its treatment remains a challenging problem in the medical field. Although western medicine treatment options have certain efficacy, they require prolonged use and are expensive. Additionally, they carry risks of multiple infections and adverse reactions like malignancies. The Chinese herbal medicine Rhododendron molle is commonly used in folk medicine for its properties of dispelling wind, removing dampness, calming nerves, and alleviating pain in the treatment of diseases like rheumatic bone diseases. In recent years, modern clinical and pharmacological studies have shown that the diterpenoids in R. molle are effective components, exhibiting immune-regulatory, anti-inflammatory, and analgesic effects. This makes it a promising candidate for treating RA with a broad range of potential applications. However, R. molle has certain toxic properties that hinder its clinical application and lead to the wastage of its resources. This study reviewed recent research progress on the mechanism of R. molle in preventing and treating RA, focusing on its chemical components, anti-inflammatory and analgesic properties and summarized the adverse reactions associated with R. molle, aiming to offer new ideas for finding natural remedies for RA and methods to reduce toxicity while enhancing the effectiveness of R. molle. The study seeks to clarify the safety and efficacy of R. molle and its extracts, providing a theoretical basis for its application prospects and further promoting the development and utilization of R. molle resources.

RESUMEN

This study aimed to explore the intervention effect of Chuanxiong-Chishao herb pair(CX-CS) on a myocardial infarction-atherosclerosis(MI-AS) mouse model and investigate its effect on the expression profile of circular RNAs(circRNAs)/long non-coding RNAs(lncRNAs) in ischemic myocardium and aorta. Sixty male ApoE~(-/-) mice were randomly assigned to a model group, high-, medium-, and low-dose CX-CS groups(7.8, 3.9, and 1.95 g·kg~(-1)), and a positive drug group(metoprolol 26 mg·kg~(-1) and simvastatin 5.2 mg·kg~(-1)), with 12 mice in each group. Male C57BL/6J mice were assigned to the sham group. The mice in the model group and the groups with drug intervention were fed on a high-fat diet for 10 weeks, followed by anterior descending coronary artery ligation. After that, the mice were fed on a high-fat diet for another two weeks to induce the MI-AS model. The mice in the sham group received normal feed, followed by sham surgery without coronary artery ligation. Mice in the groups with drug intervention received CX-CS or positive drug by gavage for four weeks from the 9th week of high-fat feeding, and those in the model group and the sham group received an equal volume of normal saline. Whole transcriptome sequencing was performed on the heart and aorta tissues of the medium-dose CX-CS group, the model group, and the sham group after administration. The results showed that the medium-and high-dose CX-CS groups showed improved cardiac function and reduced myocardial fibrosis area, and the medium-dose CX-CS group showed significantly reduced plaque area. CX-CS treatment could reverse the expression of circRNA_07227 and circRNA_11464 in the aorta of AS model and circRNA expression(such as circRNA_11505) in the heart of the MI model. Differentially expressed circRNAs between the CX-CS-treated mice and the model mice were mainly enriched in lipid synthesis, lipid metabolism, lipid transport, inflammation, and angiogenesis in the aorta, and in angiogenesis, blood pressure regulation, and other processes in the heart. CX-CS treatment could reverse the expression of lncRNAs such as ENSMUST00000162209 in the aorta of the AS model and TCONS_00002123 in the heart of the MI model. Differentially expressed lncRNAs between the CX-CS-treated mice and model mice were mainly enriched in lipid metabolism, angiogenesis, autophagy, apoptosis, and iron death in the aorta, and in angiogenesis, autophagy, and iron death in the heart. In summary, CX-CS can regulate the expression of a variety of circRNAs and lncRNAs, and its intervention mechanism in coronary heart disease may be related to the regulation of angiogenesis and inflammation in ischemic myocardium, as well as lipid metabolism, lipid transport, inflammation, angiogenesis in AS aorta.

RESUMEN

INTRODUCTION: Radiofrequency ablation and percutaneous ethanol injection are important treatment modalities for hepatocellular carcinoma patients; Whether a combination treatment yields, additional benefit still remains controversial. METHODS: A systematic review and meta-analysis was concluded. Randomized controlled trials published before January 1, 2022, from PubMed, EMBASE, Scopus, and CNKI were searched. Studies were excluded when patients received different ablative treatment or had serious liver dysfunction. The risk of bias assessment was evaluated using the Cochrane Collaboration's tool. RESULTS: Ten studies, encompassing 854 patients, with histologically proven HCC were finally analyzed. The results demonstrated that patients who received RFA-PEI had slightly improvements in 1-year overall survival (OS) [risk ratio (RR): 1.11; 95% confidence interval (CI): 1.03, 1.19, I2 = 10%], 2-year OS (RR: 1.25; 95% CI: 1.12, 1.40, I2 = 0%), 3-year OS (RR: 1.42; 95% CI: 1.11, 1.83, I2 = 38%), 1-year local recurrence-free (LRF) proportion (RR: 1.2; 95% CI: 1.01, 1.42, I2 = 61%), and complete tumor necrosis (CTN) (RR: 1.32; 95% CI: 1.14, 1.53, I2 = 45%). Nevertheless, common complications, such as fever, were found to be significant (RR: 1.78, 95% CI: 1.13, 2.80). CONCLUSION: Despite RFA-PEI appearing to be superior for HCC patients with a compensated liver in terms of OS, current evidence contained moderate to significant heterogeneity, and it was difficult to draw a definite conclusion regarding the therapeutic management in terms of LRF and CTN.

RESUMEN

PURPOSE: Personality traits often have an impact on the way individuals relate to each other as colleagues and the patients we treat. It is often perceived that distinct personality exist between different specialties and may help predict success during one's training and career. METHODS: Objective of the study was to compare the personality between surgical and medical residents. Thirty-five medical residents and 35 surgical residents completed the Revised NEO Personality Inventory, a validated measure of personality traits. A score was generated for each of the 5 major character traits namely: neuroticism(N), extraversion(E), openness(O), conscientiousness(C), agreeableness(A). Each of these traits were subdivided into 6 component facets. This was compared with sociodemographic characteristics. RESULTS: Medical residents displayed higher scores in the area of overall Agreeableness, with a mean score of 47.4 vs 40.5. Within Agreeableness facets, medical residents also displayed higher scores of straightforwardness, altruism and modesty. Surgical residents displayed higher scores in terms of overall Extraversion (52.4 vs 45.4). Within the Extraversion facets, surgical residents were also more assertive and excitement-seeking. There was no difference in the overall neuroticism domain; however, within the neuroticism facets, surgical residents had statistically higher mean scores in angry hostility and impulsiveness. Gender stratification did not result in any statistically significant difference. CONCLUSION: There are fundamental differences between personalities of medical and surgical residents. Detailed analysis of each individual's data could be useful, with proper assistance and coaching, for residents in learning more about their personalities and how these impact their clinical practice. This can be beneficial in future career counselling and the development of a more holistic medical practitioner.

RESUMEN

Covering: Up to the end of 2019.Agarwood is a resinous portion of Aquilaria trees, which is formed in response to environmental stress factors such as physical injury or microbial attack. It is very sought-after among the natural incenses, as well as for its medicinal properties in traditional Chinese and Ayurvedic medicine. Interestingly, the chemical constituents of agarwood and healthy Aquilaria trees are quite different. Sesquiterpenes and 2-(2-phenethyl)chromones with diverse scaffolds commonly accumulate in agarwood. Similar structures have rarely been reported from the original trees that mainly contain flavonoids, benzophenones, xanthones, lignans, simple phenolic compounds, megastigmanes, diterpenoids, triterpenoids, steroids, alkaloids, etc. This review summarizes the chemical constituents and biological activities both in agarwood and Aquilaria trees, and their biosynthesis is discussed in order to give a comprehensive overview of the research progress on agarwood.

RESUMEN

The G-quadruplex (G4) DNA, which has been developed as a potential anticancer target in drug screening and design, plays a crucial role in the oncogene transcription and translation. Tanshinone IIA derivatives with a planar heterocycle structure may function as G4 stabilizers. We present an innovative case of imidazole-based tanshinone IIA derivatives (1-8) especially compound 4 that improve the selectivity and the binding affinity with G4 DNA and enhance the target tumor inhibition. Cellular and in vivo experiments indicate that the tanshinone IIA derivative 4 inhibits the growth, metastasis, and angiogenesis of triple-negative breast cancer cells possibly through the stabilization of multiple G4 DNAs (e.g., c-myc, K-ras, and VEGF) to induce DNA damage. Further investigation of the intermolecular interaction and the molecular docking indicates that tanshinone IIA derivatives have better selective binding capability to various G4 DNAs than to double-stranded DNA. These findings provide guidance in modifying the molecular structures of tanshinone IIA derivatives and reveal their potential to function as specific G4 stabilizers.

RESUMEN

A series of (E)-N-2(5H)-furanonyl sulfonyl hydrazone derivatives have been rationally designed and efficiently synthesized by one-pot reaction with good yields for the first time. This green approach with wide substrate range and good selectivity can be achieved at room temperature in a short time in the presence of metal-free catalyst. The cytotoxic activities against three human cancer cell lines of all newly obtained compounds have been evaluated by MTT assay. Among them, compound 5 k exhibits high cytotoxic activity against MCF-7 human breast cancer cells with an IC50 value of 14.35 µM. The cytotoxic mechanism may involve G2/M phase arrest pathway, which is probably caused by activating DNA damage. Comet test and immunofluorescence results show that compound 5 k can induce DNA damage in time- and dose-dependent manner. Importantly, 5 k also can effectively inhibit the proliferation of MCF-7 cells and angiogenesis in the zebrafish xenograft model. It is potential to further develop N-2(5H)-furanonyl sulfonyl hydrazone derivatives as potent drugs for breast cancer treatment with higher cytotoxic activity by modifying the structure of the compound.

RESUMEN

Two new 2-(2-phenylethyl)chromone derivatives (1-2) were isolated from the ethyl acetate extract of artificial agarwood induced by holing method originating from Aquilaria sinensis (Lour.) Gilg, and they were isolated from this genus for the first time. The structures of these two new compounds were elucidated by extensive spectroscopic analyses, including UV, IR, one- and two-dimensional NMR and HRESIMS measurements. Bioassay tests of these two new compounds showed compounds 1 and 2 had weak inhibitory activity against acetylcholinesterase at a concentration of 50.0 µg/ml.

RESUMEN

Recently, cultivated "Qi-Nan" (CQN) agarwood has emerged as a new high-quality agarwood in the agarwood market owing to its similar characteristics, such as high content of resin and richness in two 2-(2-phenylethyl)chromone derivatives, 2-(2-phenylethyl)chromone (59) and 2-[2-(4-methoxyphenyl)ethyl]chromone (60), to the wild harvested "Qi-Nan" (WQN) agarwood. In this study, we compared the chemical constituents and fragrant components of two types of WQN agarwood from A. agallocha Roxb. and A. sinensis, respectively, with CQN agarwood and ordinary agarwood varieties. Additionally, we analyzed different samples of WQN agarwood and CQN agarwood by GC-MS, which revealed several noteworthy differences between WQN and CQN agarwood. The chemical diversity of WQN was greater than that of CQN agarwood. The content of (59) and (60) was higher in CQN agarwood than in WQN agarwood. For the sesquiterpenes, the richness and diversity of sesquiterpenes in WQN agarwood, particularly guaiane and agarofuran sesquiterpenes, were higher than those in CQN. Moreover, guaiane-furans sesquiterpenes were only detected by GC-MS in WQN agarwood of A. sinensis and could be a chemical marker for the WQN agarwood of A. sinensis. In addition, we summarized the odor descriptions of the constituents and established the correlation of scents and chemical constituents in the agarwood.

RESUMEN

Rhus chinensis is an important resource plant. The aqueous extract of R. chinensis roots or stems was to produce Shuguantong Syrup, which is mainly used for the treatment of coronary heart disease and angina pectoris with definite curative effect. On this basis, the crude phenolic part of R. chinensis prepared by macroporous resin was evaluated for the cardio protective effect against myocardial ischemia in mice. The results showed that the phenolic part group with oral administration at the dosages of 190.8-381.6 mg·kg~(-1), compared with the model group, reduced the values of left ventricular end systolic diameter(LVEDs) and the left ventricular end diastolic diameter(LVEDd), and increased the cardiac ejection fraction(EF) and left ventricular fractional shortening(FS) rate, which could effectively improve cardiac function and exert its anti-myocardial ischemia effect, and reduce the rising levels of creatine kinase isoenzyme(CK-MB) and lactate dehydrogenase(LDH) in serum. HE staining showed that the phenolic part group reduced the infiltration of myocardial inflammatory cells and alleviated the degree of myocardial fibrosis and collagen deposition. TUNEL staining showed that the blue-green fluorescence of the phenolic part group decreased successively, and the degree of myocardial cell apoptosis was reduced. Immunohistochemical staining suggested that it could reduce the number of positive cells for p53 protein expression and significantly improve myocardial cell damage. All above data suggested that the phenolic part group had an anti-mycardial ischemis effect. Related mechanism studies revealed that the crude phenolic part could regulate the expressions of the p53 gene(p53), Bcl-2-associated X protein(Bax), B lymphoma-2 gene(Bcl-2), and caspase-3 protein(caspase-3) in myocardial tissue, suggesting that it could reduce cardiac remodeling and myocardial ischemic damage, and improve cardiac function by inhibiting myocardial apoptosis.This research laid a foundation for the elucidation of the pharmacological ingredients R. chinensis.

RESUMEN

In this study, the compound search was completed through SciFinder and CNKI databases, and the drug-like properties were screened in FAFdrugs4 and SEA Search Server databases. In addition, based on the target sets related to acute myocardial ischemia(AMI) searched in disease target databases such as OMIM database, GeneCards database and DrugBank, a network diagram of chemical component-target-pathway-disease was established via Cytoscape to predict the potential active components of Corydalis Herba, a traditional Tibetan herbal medicine which derived from the aerial parts of Corydalis hendersonii and C. mucronifera against AMI. A protein-protein interaction(PPI) network was constructed through the STRING database and the core targets in the network were predicted. And the enrichment analyses of core targets were completed by DAVID database and R software. Furthermore, a molecular docking method was used to verify the binding of the components with core targets using softwares such as Autodock Vina. The present results showed that there were 60 compounds related to AMI in Corydalis Herba, involving 73 potential targets. The GO functional enrichment analysis obtained 282 biological processes(BP), 49 cell components(CC) and 78 molecular functions(MF). KEGG was enriched into 85 pathways, including alcoholism pathway, endocrine resistance pathway, calcium signaling pathway, cAMP signaling pathway, vascular endothelial growth factor signaling pathway and adrenergic signaling transduction pathway of myocardial cells. The results of network topology analysis showed that the key components of anti-AMI of Corydalis Herba might be tetrahydropalmatine, etrahydrocolumbamine, N-trans-feruloyloctopamine, N-cis-p-coumaroyloctopamine, N-trans-p-coumaroylnoradrenline and N-trans-p-coumaroyloctopamine, and their core targets might be CDH23, SCN4 B and NFASC. The results of molecular docking showed that the key components of Corydalis Herba had stable binding activity with the core targets. This study provides reference for further elucidation of the pharmacological effects of Corydalis Herba against AMI, subsequent clinical application, and development.

RESUMEN

AIMS/HYPOTHESIS: Myeloid-derived growth factor (MYDGF), mainly secreted by bone marrow-derived cells, has been known to promote glucagon-like peptide-1 production and improve glucose/lipid metabolism in mouse models of diabetes, but little is known about the functions of MYDGF in diabetic kidney disease (DKD). Here, we investigated whether MYDGF can prevent the progression of DKD. METHODS: In vivo experiments, both loss- and gain-of-function strategies were used to evaluate the effect of MYDGF on albuminuria and pathological glomerular lesions. We used streptozotocin-treated Mydgf knockout and wild-type mice on high fat diets to induce a model of DKD. Then, albuminuria, glomerular lesions and podocyte injury were evaluated in Mydgf knockout and wild-type DKD mice treated with adeno-associated virus-mediated Mydgf gene transfer. In vitro and ex vivo experiments, the expression of slit diaphragm protein nephrin and podocyte apoptosis were evaluated in conditionally immortalised mouse podocytes and isolated glomeruli from non-diabetic wild-type mice treated with recombinant MYDGF. RESULTS: MYDGF deficiency caused more severe podocyte injury in DKD mice, including the disruption of slit diaphragm proteins (nephrin and podocin) and an increase in desmin expression and podocyte apoptosis, and subsequently caused more severe glomerular injury and increased albuminuria by 39.6% compared with those of wild-type DKD mice (p < 0.01). Inversely, MYDGF replenishment attenuated podocyte and glomerular injury in both wild-type and Mydgf knockout DKD mice and then decreased albuminuria by 36.7% in wild-type DKD mice (p < 0.01) and 34.9% in Mydgf knockout DKD mice (p < 0.01). Moreover, recombinant MYDGF preserved nephrin expression and inhibited podocyte apoptosis in vitro and ex vivo. Mechanistically, the renoprotection of MYDGF was attributed to the activation of the Akt/Bcl-2-associated death promoter (BAD) pathway. CONCLUSIONS/INTERPRETATION: The study demonstrates that MYDGF protects podocytes from injury and prevents the progression of DKD, providing a novel strategy for the treatment of DKD.

RESUMEN

BACKGROUND: Reablement is a philosophy of change in long-term care (LTC). Assessing the knowledge and competence of LTC professionals who provide reablement services is vital in LTC research. This study aimed to develop a scale for the assessment of long-term care reablement literacy (LTCRL) and employ this scale to assess the performance of home care workers in Taiwan. METHODS: To develop this scale, we employed the modified Delphi technique based on the theoretical framework of health literacy and the content of service delivery in reablement. Home care workers from northern, central, and southern Taiwan were selected through purposive sampling (N = 119). Participants answered a self-administered questionnaire that included items related to basic demographic characteristics and questions to assess LTCRL. RESULTS: Based on the experts' consensus on the procedure of the modified Delphi technique, the LTCRL assessment sale consists of 29 questions on four aspects of knowledge acquisition: the abilities to access/obtain, understand, process/appraise, and apply/use. The results revealed that higher education levels and better Chinese language proficiency are associated with higher LTCRL outcomes among home care workers. CONCLUSIONS: The LTCRL assessment scale based on a modified Delphi technique is useful and feasible for evaluating LTCRL in home care workers who provide reablement services in Taiwan.
