BACKGROUND: Measurement of person-centred care (PCC) outcomes is underdeveloped owing to the complexity of the concept and lack of conceptual clarity. A framework conceptualizing outpatient PCC in rheumatology nurse-led clinics has therefore been suggested and operationalized into the PCC instrument for outpatient care in rheumatology (PCCoc/rheum). OBJECTIVE: The aim of the present study was to test the extent to which the PCCoc/rheum represents the underpinning conceptual outpatient PCC framework, and to assess its measurement properties as applied in nurse-led outpatient rheumatology clinics...

Aseptic loosening due to wear particles is a serious challenge for orthopedic surgeons, sabotaging the long-term success of total joint arthroplasty. The existing treatments for aseptic loosening are still far from satisfactory, necessitating more aggressive drug exploration. Here, we examined the effect of emodin on titanium particle-induced osteolysis and further investigated its underlying mechanism in vivo and in vitro. Thirty-two C57BL/6 mice were randomly assigned into four groups: the Sham group (sham operation with vehicle injection), Vehicle group (titanium particle treatment with vehicle injections), Low group (titanium particle treatment with injections of 10 mg/kg/day emodin) and High group (titanium particle treatment with injections of 50 mg/kg/day emodin)...

Alternatively activated macrophages (AAMs) are not only associated with asthma but also lead to asthmatic airway inflammation and remodeling. Inhibition of AAMs is an alternative therapeutic strategy for treating asthma. In this study we investigated whether emodin (1,3,8-trihydroxy-6-methylanthraquinone), isolated from the rhizome of Rheum palmatum, alleviated asthmatic airway inflammation and reduced AAM polarization in a murine asthma model. Mice were sensitized with a triple allergen mix containing dust mite, ragweed and aspergillus (DRA)...

BACKGROUND: Person-centred care (PCC) is considered a key component of effective illness management and high-quality care. However, the PCC concept is underdeveloped in outpatient care. In rheumatology, PCC is considered an unmet need and its further development and evaluation is of high priority. The aim of the present study was to conceptualize and operationalize PCC, in order to develop an instrument for measuring patient-perceived PCC in nurse-led outpatient rheumatology clinics. METHODS: A conceptual outpatient PCC framework was developed, based on the experiences of people with rheumatoid arthritis (RA), person-centredness principles and existing PCC frameworks...

Potato late blight (PLB) caused by Phytophthora infestans (Pi) is the most harmful disease in potato production worldwide. In organic farming, copper is used despite its persistence in soil and toxicity to soil organisms. To replace copper, suspensions of powders from three promising botanicals, including bark of buckthorn (Frangula alnus, FA), roots of medicinal rhubarb (Rheum palmatum) and galls of the nutgall tree (Galla chinensis), were tested in multi-year field experiments. The current study shows for the first time that botanicals could replace copper under field conditions and best PLB reduction on leaves was achieved with FA, reaching a level close to that of 2 to 3 kg copper per hectare and year...

The separation of polar compounds by high-speed counter-current chromatography is still regarded as a challenge. In this study, an efficient strategy for the separation of three polar compounds from Rheum tanguticum has been successfully conducted by using high-speed counter-current chromatography. X-5 macroporous resin chromatography was used for the fast enrichment of the target compounds. Then, the target fraction was directly introduced into high-speed counter-current chromatography for separation using ethyl acetate/glacial acetic acid/water (100:1:100, v/v) as the solvent system...

Pancreatitis is an inflammatory disease that is responsible for substantial morbidity and mortality, and it can induce pancreatic necrosis that starts within pancreatic acinar cells in severe cases. Emodin, a pleiotropic natural product isolated from the Chinese herb Rheum palmatum L ., has effective anti-inflammatory activities. In this paper, we investigated the protective effects and molecular mechanism of emodin against sodium taurocholate (STC)-induced pancreatic acinar cells injury in vitro and in vivo ; and the results showed that emodin could significantly alleviate STC-induced pancreatic acinar cells injury through decreasing trypsin, amylase and the release of inflammatory factors (tumor necrosis factor alpha, interleukin-1β, and interleukin-6)...

The transcription factor hypoxia-inducible factor-1 (HIF-1) consists of oxygen-sensitive HIF-1α and constitutive HIF-1β. HIF-1α is undetectable in normal cells, but cancer cells frequently express HIF-1α to support their growth, angiogenesis, and high glycolysis (also known as the Warburg effect). The Warburg effect in cancer cells increases energy expenditure and thus participates in cancer-induced metabolic disorder, cancer cachexia. In the present study, we investigated whether two components of Rheum palmatum, emodin and rhein, inhibited HIF-1α expression in human pancreatic cancer cells and whether the inhibiting effect, if any, attenuated cancer cachexia...

Development of multidrug resistance (MDR) is a continuous clinical challenge partially due to the overexpression of P-glycoprotein (P-gp) for chronic myelogenous leukemia (CML) patients. Herein, we evaluated the inhibitory potency of emodin, a natural anthraquinone derivative isolated from Rheum palmatum L, on P-gp in P-gp positive K562/ADM cells. Competition experiments combined with molecular docking analysis were utilized to investigate the binding modes between emodin and binding sites of P-gp. Emodin reversed adriamycin resistance in K562/ADM cells accompanied with the decrease of P-gp protein expression, further increasing the uptake of rhodamine123 in both K562/ADM and Caco-2 cells, indicating the inhibition of P-gp efflux function...

For the European Pharmacopoeia (Ph. Eur.) herbal monograph draft of Cassia angustifolia Vahl. and Cassia senna L. leaves and pods, a safety limitation of aloe-emodin and rhein was proposed, due to toxicological concerns. A quantitative, analytical method of the anthraquinone aglycones in all Ph. Eur. monographed herbal laxatives is of interest. A rational method development for the aglycones aloe-emodin, rhein, emodin, chrysophanol, and physcion in five herbal drugs was realized by using 3D chromatographic modelling (temperature, solvent, and gradient time) and design of experiment (DOE) software (DryLab(®) 4)...

Under the traditional processing theory "wine processing could promote the efficacy", Rhubarb after wine processing could treat the upper energizer diseases such as red swelling, and breath sores. Processing changes the medicinal properties of rhubarb, and thus results in different focuses in clinical application. In this study, a sensitive and specific method was developed for the determination of aloe-emodin, rhein and emodin in rats tissue. Rhubarb raw materials and its wine processed decoction were given to SD rats respectively by gavage administration, and then the contents of aloe-emodin, rhein and emodin in the tissues (heart, lung, brain, liver, kidney) were determined by HPLC-MS to explore the effect of wine processing on free anthraquinones in rat tissues...
