ABSTRACT
Purpose: To investigate the clinical value of adding Jin-gu-lian (JGL) capsules into rheumatoid arthritis (RA) treatment by examining its impact on disease activity and quality of life (QoL) through a real-world study (RWS). Patients and methods: RWS was conducted to compare the inflammatory markers, including IgM-RF, ESR, and CRP, between RA patients treated with only Western medicine (reference group) and Western medicine plus JGL (study group) during one-year follow-up. The clinical data was acquired from the hospital information system (HIS). Telephone call-based follow-up on QoL (SF-36) and accompanying symptoms, including gastrointestinal complaints, attacks of pneumonia, herpes zoster, URTIs, UTIs, and LTBIs. Finally, the anti-rheumatic drugs given to both groups were also compared. RWS was further validated for its feasibility by performing studies with hydroxychloroquine (HCQ) treatment, which is a commonly used anti-rheumatic drug for RA with mild effect. Results: The study group failed to show a significant effect on inflammatory markers, especially on the CRP levels, indicating no additional clinical value of supplementing with JGL. Similarly, at the endpoint, no significant differences between the two groups on QoL and related symptoms were observed. Our study suggests that the patients in the study group might need more anti-rheumatic drugs to fill the treatment insufficiency, and the application ratio of NSAIDs would be significantly higher than the reference group. By conducting this study on HCQ treatment, the positive aspects of controlling disease activity and reducing NSAIDs application were found, which demonstrates the utility of performing the RWS to evaluate the effect of JGL. Conclusion: Adding JGL did not significantly improve the clinical efficacy of RA treatment by this RWS. Folk herbal prescriptions such as JGL are suggested to underwent strict clinical trials before application.
ABSTRACT
BACKGROUND: Elderly rheumatoid arthritis (ERA) population faces multiple treatment dilemma. Here we aim to investigate if Gancao Nourishing-Yin decoction (GCNY) added to methotrexate (MTX) exhibit better effects in an ERA mice model. METHODS: ERA mice model was established by adding D-galactose (Dgal) to collagen-induced arthritis (CIA) mice. The model was then assigned into control group (CIA + Dgal), MTX treatment group (MTX), GCNY treatment group (GCNY), and integrative treatment group (MTX + GCNY). Pathological scoring was performed to evaluate the severity between the groups. Proteomic analysis was applied to investigate the secretory phenotype of the ERA mouse model and the underlying mechanism of GCNY, MTX and their combination. Representative cytokines related to proteomic results were further validated by ELISAs. RESULTS: CIA + Dgal mice showed more aggressive joints damage than the CIA mice. Besides changes in the inflammatory pathway such as Pi3k-Akt signaling pathway in both model, differential expressed proteins (DEPs) indicated metabolism-related pathways were more obvious in CIA + Dgal mice. Low-dose MTX failed to show pathological improvement in CIA + Dgal mice, while GCNY improved joints damage significantly. Besides down-regulated inflammation-related targets, GCNY-regulated DEPs (such as Apoc1 ~ 3, Grk2 and Creb3l3) were broadly enriched in metabolism-related pathways. MTX + GCNY showed the best therapeutic effect, and the DEPs enriched in a variety of inflammatory,metabolism and osteoclast differentiation signaling pathway. Notably, MTX + GCNY treatment up-regulated Dhfr, Cbr1, Shmt1 involved in folic acid biosynthesis and anti-folate resistance pathways indicated a coincidence synergic action. ELISAs confirmed CPR and Akt that elevated in CIA + Dgal mice were significantly ameliorated by treatments, and adding on GCNY elevated folic acid levels and its regulator Dhfr. CONCLUSION: Aging aggravated joints damage in CIA, which probably due to metabolic changes rather than more severe inflammation. GCNY showed significant effects in the ERA mice model especially when integrated with MTX to obtain a synergic action.
ABSTRACT
PURPOSE: To investigate the coverage of pit and fissure sealants in primary and middle school students of Hangzhou city, and to explore the causes of unsealing students. METHODS: An analysis of sealing rate and unsealing causes of eligible children in Hangzhou city was carried out, using 3-year data of pit and fissure sealants program sponsored by the government. Based on the results, the validity of pit and fissure sealants as a government-sponsored public health program was evaluated. RESULTS: The sealing rate was 52.89%. The main reasons of unsealing were uneruption and incomplete eruption of teeth when the medical teams went to school for pit and fissure sealing. CONCLUSIONS: The main reason of unsealing is eruption issue, which can be controllable. Some scientific adjustments need to be made to improve the coverage, such as increasing sealing times considering the difference of teeth eruption.
