An imbalance in osteogenesis and osteoclastogenesis is a crucial pathological factor in the development of osteoporosis. Osteoclasts (OCs) play a pivotal role in osteoporosis, whose new therapy exploration has been focused on the suppression of OC formation. Sophoridine is found from the Chinese traditional food sophora flower to exhibit anti-osteoporosis capacity by screening. This study is focused on its anti-osteoporosis mechanism evaluation. The anti-osteoporosis effect of sophoridine, (15 mg kg-1 body), was evaluated in ovariectomized (OVX) mice by monitoring changes in bone histomorphometry index, formation of osteoclasts from blood-derived mononuclear cells, and changes in the synthesis of pro-osteoclastogenic cytokines. Signal pathways were investigated by QPCR, Western blot, and immunofluorescence. Sophoridine has a significant anti-osteoporosis effect in vivo, which can inhibit RANKL-induced OC formation, the appearance of OC-specific marker genes, and OC marker protein in vitro. Mechanistically, sophoridine dose- and time-dependently blocks the RANKL-induced OC formation and the activation of ERK and c-Fos as well as the induction and nucleus translocation of NFATc1. Sophora flower might be a useful alternative functional food in preventing or treating osteoporosis.
Objective: To establish an HPLC-ELSD fingerprint of the whole herbs of Morina nepalensis and perform the correlation analysis of chemical components of the herb and nitric oxide (NO) production inhibition.; Method: HPLC-ELSD assay was performed to evaluate 10 batches of M. nepalensis herbs. The chromatographic conditions were as following: Eclipse XDB C18 column (4.6 mm x 150 mm, 5 microm), water (A) and acetonitrile (B) as a gradient mobile phases, flow rate 1.0 mL x min(-1), and column temperature at 35 degress C. Evaporative light-detection conditions: atomization temperature at 104 degrees C, the flow rate of N2 2.8 L x min(-1) and 10 microL sample injection. Chromatographic fingerprint was developed, and the inhibition activity of production of NO in lipopolysaccharide-induced macrophages was also analyzed. The similarity and correlation analysis between the HPLC-ELSD fingerprints and NO production inhibition were carried out by PLS method.; Result: The common mode for M. nepalensis herb fingerprint was established, including 15 common characteristic peaks. Among them, 7 peaks were positively correlated with the NO production inhibition. According to the assessment on the similarity of 10 batches of samples, a similarity of over 0.90 were shown in HPLC-ELSD fingerprint and all samples were separated into two groups.; Conclusion: This method can be used to assess the quality of M. nepalensis, which provides a reliable method for scientific assessment and quality control.;
Around 70-80% of drugs used in traditional Tibetan medicine (TTM) come from Qinghai Tibet Plateau, the majority of which are plants. The biological and medicinal culture diversity on Qinghai Tibet Plateau are amazing and constitute a less tapped resource for innovative drug research and development. Meanwhile, the problem of the exhausting Tibetan medicine resources is worrying. Here, the latest awareness, as well as the gaps of the traditional Tibetan medicinal plant issues in drug development and clinical usage of TTM compounds, was systematically reviewed and highlighted. The TTM resource studies should be enhanced within the context of deeper and more extensive investigations of molecular biology and genomics of TTM plants, phytometabolites and metabolomics and ethnopharmacology-based bioactivity, thus enabling the sustainable conservation and exploitation of Tibetan medicinal resource.

BACKGROUND: Despite their high symptom burden and poor prognosis, evidence-based supportive care interventions for adults with high-grade glioma (HGG) and their caregivers are lacking. Thus, we aimed to establish feasibility of a patient-caregiver dyadic yoga program (DYP) for newly diagnosed HGG patients and their family caregivers targeting quality-of-life (QOL) outcomes.METHOD: In this single-arm pilot trial, dyads participated in a 12-session DYP program across the course of patients' radiotherapy. The intervention focused on breathing exercises, gentle movements, and guided meditations. We tracked feasibility data and assessed levels of cancer-related symptoms (MD Anderson Symptom Inventory [MDASI]), depressive symptoms (Centers for Epidemiological Studies-Depression scale), fatigue (Brief Fatigue Inventory), sleep disturbances (Pittsburgh Sleep Quality Index [PSQI]), and overall mental and physical QOL (36-item Short-Form Survey [SF-36]) at baseline and post-DYP, which was at the end of radiotherapy.
RESULTS: We approached 6 dyads of which 5 dyads (86%) consented and completed all 12 sessions and pre/post assessments. All patients (mean age: 52 years, 80% female, 80% grade IV) and caregivers (mean age: 58 years, 80% female, 60% spouses) perceived benefit from the program. Paired t tests revealed a marginally significant, yet clinically meaningful, decrease in patient's cancer symptoms ( t = 2.32, P = .08; MDASI mean; pre = 1.75, post = 1.04). There were clinically significant reductions in patient sleep disturbances (PSQI mean: pre = 10.75, post = 8.00) and improvements in patient and caregiver mental QOL (MCS of SF-36 mean: pre = 42.35, post = 52.34, and pre = 45.14, post = 51.43, respectively).
CONCLUSIONS: This novel supportive care program appears to be safe, feasible, acceptable, and subjectively useful for HGG patients and their caregivers. There was also preliminary evidence regarding QOL treatment gains for both patients and caregivers.
