RESUMO

BACKGROUND: Non-pharmacological interventions have a myriad of available intervention options and contain multiple components. Whether specific components of non-pharmacological interventions or combinations are superior to others remains unclear. The main aim of this study is to compare the effects of different combinations of non-pharmacological interventions and their specific components on health-related outcomes in adults with subjective cognitive decline. METHODS: PubMed, Embase, Cochrane, CINAHL, PsycINFO, CENTRAL, Web of Science, and China's two largest databases, CNKI and Wanfang, were searched from inception to 22nd, January 2023. Randomized controlled trials using non-pharmacological interventions and reporting health outcomes in adults with subjective cognitive decline were included. Two independent reviewers screened studies, extracted data, and assessed risk of bias. Component network meta-analysis was conducted employing an additive component model for network meta-analysis. This study followed the PRISMA reporting guideline and the PRISMA checklist is presented in Additional file 2. RESULTS: A total of 39 trials with 2959 patients were included (range of mean ages, 58.79-77.41 years). Resistance exercise might be the optimal intervention for reducing memory complaints in adults with subjective cognitive decline; the surface under the cumulative ranking p score was 0.888, followed by balance exercise (p = 0.859), aerobic exercise (p = 0.832), and cognitive interventions (p = 0.618). Music therapy, cognitive training, transcranial direct current stimulation, mindfulness therapy, and balance exercises might be the most effective intervention components for improving global cognitive function (iSMD, 0.83; 95% CI, 0.36 to 1.29), language (iSMD, 0.31; 95% CI, 0.24 to 0.38), ability to perform activities of daily living (iSMD, 0.55; 95% CI, 0.21 to 0.89), physical health (iSMD, 3.29; 95% CI, 2.57 to 4.00), and anxiety relief (iSMD, 0.71; 95% CI, 0.26 to 1.16), respectively. CONCLUSIONS: The form of physical activity performed appears to be more beneficial than cognitive interventions in reducing subjective memory complaints for adults with subjective cognitive decline, and this difference was reflected in resistance, aerobic, and balance exercises. Randomized clinical trials with high-quality and large-scale are warranted to validate the findings. TRIAL REGISTRATION: PROSPERO registry number. CRD42022355363.

RESUMO

Twelve new diterpenoids based on two rare skeletal types, namely, paralianones A-D (1-4) and pepluanols A-H (5-12), along with five known compounds, were isolated from an acetone extract of Euphorbia peplus. Their structures were proposed based on 1D and 2D NMR spectroscopic data analysis. These diterpenoids were evaluated for potential anti-inflammatory activity in a lipopolysaccharide-stimulated mouse macrophage cellular model. Compounds 3, 4, 11, 13, and 16 displayed moderate inhibitory effects on NO inhibition, with IC50 values ranging from 29.9 to 38.3 µM.

RESUMO

Although adsorbents are good candidates for removing phosphorus and heavy metals from wastewater, the use of biosorbents for the sequential treatment of phosphorus and copper has not yet been studied. Porous chitosan (CS)-based biosorbents (CGBs) were developed to adsorb phytic acid (PA), a major form of organic phosphate. This first adsorbate (PA) further served as an additional ligand (P-type ligand) for the CGBs (N-type ligand) to form a complex with the second adsorbate (copper). After the adsorption of PA (the first adsorbate), the spent CGBs were recycled and used as a new adsorbent to adsorb Cu(II) ions (the second adsorbate), which was expected to have a dual coordination effect through P, N-ligand complexation with copper. The interactions and complexation between CS, PA and Cu(II) ions on the PA-adsorbed CGBs (PACGBs) were investigated by performing FTIR, XPS, XRD, and SEM-EDS analyses. The PACGBs exhibited fast and enhanced adsorption of Cu(II) ions, owing to the synergistic effect of the amino groups of CS (the original ligand, N-type) and the phosphate groups of PA (an additional ligand, P-type) on the adsorption of Cu(II) ions. This is the first time that sequential removal of phosphorus and heavy metals by biosorbents has been performed using biosorbents.

RESUMO

BACKGROUND AND PURPOSE: Mistletoe lectin-I (ML-I), the main anti-cancer component of mistletoe extracts, was originally thought to act exclusively on 28S rRNA. Here, we investigate the down-regulating effect and mechanism of CM-1, an ML-I isolated from Chinese mistletoe, on some miRNAs. EXPERIMENTAL APPROACH: The anti-cancer effects of CM-1 were assessed in vitro and in vivo in colorectal cancer cells. The miRNAs down-regulated by CM-1 were identified by miRNA microarray assay and validated by qRT-PCR analysis. The suppression of host gene transcription or by degradation of precursors was determined by qRT-PCR and enzyme activity assays respectively. The qRT-PCR, Western blot and immunohistochemistry were used to examine the expression of their target gene and related downstream effector. Cell proliferation was assayed in stably transfected HEK-293 cells with different levels of these miRNAs. KEY RESULTS: CM-1 showed prominent anti-neoplastic activity towards CLY and HT-29 cells both in vitro and in vivo. The miR-135a&b were the miRNAs most down-regulated by CM-1. Their host gene transcription was largely up-regulated, while their precursors were degraded directly by CM-1. The expression of their target gene adenomatous polyposis coli and the phosphorylation of related effector ß-catenin were both significantly up-regulated. The IC(50) values of CM-1 on derivative HEK-293 cells with high miR-135a&b levels were 2-4 times lower than that of control cells. CONCLUSIONS AND IMPLICATIONS: CM-1 down-regulated some miRNAs by degrading their precursors, which contributes to its prominent anti-cancer activity.

RESUMO

OBJECTIVE: To evaluate the clinical outcome of surgical treatment of the posterior dislocation of the elbow with coroniod and radial head fractures. METHODS: From January 2004 to March 2009, 9 patients with terrible triad of the elbow were reviewed. There were 7 males and 2 females (4 left elbows and 5 right elbows), with an average age of 41.2 years, ranged from 21 to 67 years. The radial head fractures were classified according to the Schatzker-Tile criteria: 4 patients had the fractures of type I, 3 patients had type II and 2 patients had type III. The ulnar coronoid fractures were classified according to the Regan-Morrey criteria: 2 patients had the fractures of type I, 5 patients had type II and 2 patients had type III. The general approach was used to repair the damaged structures sequentially from deep to superficial, through coronoid, anterior capsule, radial head, and lateral ligament complex to common extensor origin. If there was valgus instability in the elbow after the operation, the medial collateral ligament should be repaired with nonabsorption sutures. The plaster was applied for 7 to 10 days with elbow flexion in 90 degrees and the forearm in full pronation. Unrestricted motions and rehabilitation began at the 8th week after operation. Recovery of regular occupation depended on the degree of physical activity required, and it typically took 3 months for heavy physical laborers to return to work. RESULTS: All the patients were followed up from 6 months to 5 years, with a mean duration of (31 +/- 6) months. At the 3rd month after operation, the mean rang of motion in flexion and extension of the elbow was (102 +/- 3) degrees (ranged from 80 degrees to 110 degrees), and the mean range of motion in pronation and supination of the forearm was (135 +/- 6) degrees (100 degrees to 150 degrees). According to the criteria of the Mayo scoreing system, the results were excellent in 5 cases, good in 3 cases, and fair in 1 case. Three patients had heterotopic ossification at the 6th month after operation. Among them, 2 patients had no effects on elbow function and were not treated, 1 patient had effects on flexion-extension of the elbow and was treated with resection of heterotopic ossification through lateral approach combined with early rehabilitation, the MEP score of the patient improved from fair to good. CONCLUSION: The key points for treating the terrible triad of the elbow are to restore the elbow normal anatomy and early rehabilitation to avoid the elbow stiff.
