Abstract

Introduction: This study evaluated algorithm-based qualitative (ABQ) method for vertebral fracture (VF) evaluation with reference to semi-quantitative (SQ) method and bone mineral density (BMD) measurement. Methods: Mr. OS (Hong Kong) and Ms. OS (Hong Kong) represent the first large-scale cohort studies on bone health in elderly Chinese men and women. The current study compared Genant's SQ method and ABQ method in these two cohorts. Based on quantitative measurement, the severity of ABQ method detected fractures was additionally classified into grade-1, grad-2, and grade-3 according to SQ's deformity criteria. The radiographs of 1,954 elderly Chinese men (mean: 72.3 years) and 1,953 elderly Chinese women (mean: 72.5 years) were evaluated. Results: according to ABQ, grade-1,-2,-3 VFs accounted for 1.89%, 1.74%, 2.25% in men, and 3.33%, 3.07%, and 5.53% in women. In men and women, 15.7% (35/223) and 34.5% (48/139) of vertebrae with SQ grade-1 deformity were ABQ(+, with fracture) respectively. In men and women, 89.7% (35/39) and 66.7% (48/72) of vertebrae with ABQ grade-1 fracture had SQ grade-1 deformity. For grade-1 change, SQ (-, negative without fracture) & ABQ (+, positive with vertebral cortex line fracture) subjects tend to have a lower BMD than the SQ(+)& ABQ(-) subjects. In subjects with SQ grade-2 deformity, those were also ABQ(+) tended to have a lower BMD than those were ABQ(-). In all grades, SQ(-)&ABQ(-) subjects tended to have highest BMD, while SQ(+)&ABQ(+)subjects tended to have lowest BMD. Conclusion: ABQ method may be more sensitive to VF associated mild lower BMD than SQ method., Comment: 26 pages,4 figures, 6 tables

Abstract

Artemisinin is a natural sesquiterpene lactone obtained from the traditional Chinese medicinal herb Artemisia annua L. (qinghao). Artemisinin and its derivatives share an unusual endoperoxide bridge and are extensively used for malaria treatment worldwide. In addition to antimalarial activities, artemisinin and its derivatives have been reported to exhibit promising anticancer effects in recent decades. In this review, we focused on the research progress of artemisinin and its derivatives with potential anticancer activities. The pharmacological effects, potential mechanisms, and clinical trials in cancer therapy of artemisinin and its derivatives were discussed. This review may facilitate the future exploration of artemisinin and its derivatives as effective anticancer agents. [ABSTRACT FROM AUTHOR]

Abstract

Allergic rhinitis (AR) is a series of allergic reactions to allergens in the nasal mucosa and is one of the most common allergic diseases that affect both children and adults. Shi-Bi-Lin (SBL) is the modified formula of Cang Er Zi San (CEZS), a traditional Chinese herbal formula used for treating AR. Our study aims to elucidate the anti-inflammatory effects and mechanisms of SBL in house dust mite-induced AR by regulating gut microflora metabolism. In vivo studies showed that nasal allergies and the infiltration of inflammatory cells in the nasal epithelium were significantly suppressed by SBL. Moreover, SBL restored the impaired nasal epithelial barrier function with an increased tight junction protein expression and reduced the endothelial nitric oxide synthase (eNOS). Interestingly, SBL significantly reconstituted the abundance and composition of gut microbiota in AR mice; it increased the relative abundance of potentially beneficial genera and decreased the relative abundance of harmful genera. SBL also restored immune-related metabolisms, which were significantly increased and correlated with suppressing inflammatory cytokines. Furthermore, a network analysis and molecular docking indicated IL-6 was a possible target drug candidate for the SBL treatment. SBL dramatically reduced the IL-6 level in the nasal lavage fluid (NALF), suppressing the IL-6 downstream Erk1/2 and AKT/PI3K signaling pathways. In conclusion, our study integrates 16S rRNA sequencing, microflora metabolism, and network pharmacology to explain the immune mechanism of SBL in alleviating HDM-induced allergic rhinitis.

Abstract

A simple setup for rehabilitation training was established in 2007 in a rural area of Shanxi Province, China. It made use of an underused facility created for elderly people’s leisure time. Simple equipment for rehabilitation training was provided free for the users, and instructions were given by rehab experts, Traditional medical doctors, and social workers. This rural Service Station must be the first of its kind in rural China and deserves scrutinizes for its unique nature. After 5 years of service, a service evaluation of its service nature, service providers, users, and special orientations was completed. It is hoped that this Service Station could be taken as a model of similar rural development in China.

Abstract

The global pandemic of COVID-19, caused by severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) has been developing all over the world for more than 3 years. In late 2020, several variants of concern of SARS-CoV-2 virus emerged, with increased viral fitness and transmissibility by mutations of the spike proteins of the viral particle, denting hopes of the use of early-generation vaccines for a widespread protective immunity against viral infection. The use of adjuvants may enhance the immune responses of the conventional application of the COVID-19 vaccine. We have shown that the water extract of 2 β-glucan–enriched immunostimulating natural products, Astragalus membranaceus (Fisch.) Bge. (AM) and Coriolus versicolor (CV), could induce innate immunity-related cytokines from human monocytes (CCL5, interleukin [IL]-6, IL-10, and tumor necrosis factor α) and monocyte-derived dendritic cells (IL-1β, IL-10, IL-12, and tumor necrosis factor α). Using BALB/c mice, orally administrated AM and CV (1,384 and 742 mg/kg/d) for 4 d after vaccination, respectively, could enhance (1) the immunoglobulin G binding activities of BNT162b2 vaccination against ancestral and Delta SARS-CoV-2 spike proteins by 5.8- and 4.3-fold, respectively; (2) the immunoglobulin G3 subclass production of BNT162b2 vaccination against ancestral and variant SARS-CoV-2 spike proteins; and (3) the in vitro antibody-neutralizing activities of BNT162b2 vaccinated mice. In conclusion, combining AM and CV was effective in acting as an oral adjuvant with the messenger RNA vaccine BNT162b2 to improve the antigen binding activities against SARS-CoV-2 ancestral and variant SARS-CoV-2 spike proteins, probably via trained immunity of macrophages and dendritic cells.
