Oral frailty: a concept analysis.

BACKGROUND: Oral frailty has become a worldwide problem among older adults. Although researchers have conducted various studies on oral frailty, its definition remains controversial. PURPOSE: To clarify the concept of oral frailty. METHODS: Online databases PubMed, Web of Science, CINAHL, Cochrane Library, ProQuest, China National Knowledge Infrastructure (CNKI), China Science and Technology Journal Database (VIP), and Wanfang database were searched from inception to September 20, 2023. The reference lists of relevant studies were searched manually. Eligible articles, theses, and books were analyzed using Walker & Avant's concept analysis model. RESULTS: The attributes of oral frailty were abnormal oral structure and/or decline in multi-faceted oral function and coexisting decline in physical, cognitive and social functions. Its antecedents were aging, social frailty, and severe periodontitis, whereas its consequences were decline in physical health and mental health, social withdrawal, lower quality of life and systemic frailty. CONCLUSION: Oral frailty could result in worse conditions among older adults physically, psychologically and socially. Tools based on the concept analysis need to be developed to comprehensively assess oral frailty.

Efficacy of Huoxiang Zhengqi dropping pills and Lianhua Qingwen granules in treatment of COVID-19: A randomized controlled trial.

BACKGROUND: With the global epidemic of coronavirus disease (COVID-19), China has made progress in the prevention and control of the epidemic, and traditional Chinese medicine (TCM) has played a key role in dealing with the disease's effects on the respiratory system. This randomized controlled clinical trial evaluated the clinical efficacy and prognosis of Huoxiang Zhengqi dropping pills and Lianhua Qingwen granules in patients with COVID-19. METHODS: A total of 283 patients participated in this clinical trial, and participants were randomly assigned to receive either 1) Huoxiang Zhengqi dropping pills and Lianhua Qingwen granules or 2) Linahua granules, both combined with western medicine, or 3) western medicine alone for 14 days. At the end of the trial, the improvement and resolution rates of clinical symptoms and the rate of patients who progressed to severe disease status were evaluated. RESULTS: After 14 days of treatment, there was no significant difference in the improvement rate of clinical symptoms among the three groups (P > 0.05). Huoxiang Zhengqi dropping pills combined with Lianhua Qingwen granules has advantages in the treatment of nausea, vomiting and limb soreness. During treatment, all participants were treated with western medicine, and there was a significant difference in the use of macrolides among the three groups (P < 0.05). Specifically, the utilization rate of antibiotics in the western medicine group was significantly greater than that of the other two groups. Among the 182 diagnosed patients who completed this clinical trial, 13 patients progressed to severe disease, including one case in the Huoxiang + Lianhua group (1.6 %), five cases in the Lianhua group (8.6 %), and seven cases in the western medicine group (11.1 %). There was no statistical differences in this rate among the three groups (P > 0.05). However, the proportion of patients who progressed to severe disease in the Huoxiang + Lianhua group was the lowest, suggesting that the combination of TCM with western medicine has a potential advantage in improving the prognosis of patients with COVID-19. CONCLUSION: The use of Huoxiang Zhengqi dropping pills and Lianhua Qingwen granules combined with western medicine may have clinical advantages for COVID-19 patients in improving clinical symptoms, reducing utilization rate of anti-infective drugs, and improving patient prognosis, which could pave the way for the use of complementary medicine in treating this infection.

GAS6-AS2 Promotes Hepatocellular Carcinoma via miR-3619-5p/ARL2 Axis Under Insufficient Radiofrequency Ablation Condition.

Background: Hepatocellular carcinoma (HCC) is a common malignancy worldwide. Radiofrequency ablation (RFA) is applied for treating HCC; however, insufficient RFA promotes HCC development and accelerates HCC recurrence. Therefore, the molecular functions underlying this process have gradually attracted attention. Objective: We sought to examine whether GAS6-AS2 (also known as GAS6-DT: growth arrest specific 6 divergent transcript) played a role in the development of HCC after insufficient RFA. Materials and Methods: The in vitro model was established by heating Huh7 and MHCC97 cells in water bath at 47°C, named as Huh7-H and MHCC97-H. Colony formation, transwell and Western blot assays were conducted for functional analysis. Results: GAS6-AS2 was upregulated in Huh7-H and MHCC97-H cells relative to Huh7 and MHCC97 cells. GAS6-AS2 deficiency hampered cell proliferation, migration, invasion, epithelial-mesenchymal transition, and stemness in Huh7-H and MHCC97-H cells. Moreover, microRNA-3619-5p (miR-3619-5p) combined with GAS6-AS2 and ARL2 (ADP ribosylation factor-like GTPase 2) was the target gene of miR-3619-5p. GAS6-AS2 served as the competing endogenous RNA (ceRNA) of ARL2 via absorbing miR-3619-5p. Conclusion: On the whole, present study uncovered a novel ceRNA mechanism of GAS6-AS2/miR-3619-5p/ARL2 in HCC after insufficient RFA, which might shed a new insight into treatment of HCC after insufficient RFA.
