The Effects of Modified Simiao Decoction in the Treatment of Gouty Arthritis: A Systematic Review and Meta-Analysis.

The modified Simiao decoctions (MSD) have been wildly applied in the treatment of gouty arthritis in China. However, the evidence needs to be evaluated by a systematic review and meta-analysis. After filtering, twenty-four randomised, controlled trials (RCTs) comparing the effects of MSD and anti-inflammation medications and/or urate-lowering therapies in patients with gouty arthritis were included. In comparison with anti-inflammation medications, urate-lowering therapies, or coadministration of anti-inflammation medications and urate-lowering therapies, MSD monotherapy significantly lowered serum uric acid (p < 0.00001, mean difference = -90.62, and 95% CI [-128.38, -52.86]; p < 0.00001, mean difference = -91.43, and 95% CI [-122.38, -60.49]; p = 0.02, mean difference = -40.30, and 95% CI [-74.24, -6.36], resp.). Compared with anti-inflammation medications and/or urate-lowering therapies, MSD monotherapy significantly decreased ESR (p < 0.00001; mean difference = -8.11; 95% CI [-12.53, -3.69]) and CRP (p = 0.03; mean difference = -3.21; 95% CI [-6.07, -0.36]). Additionally, the adverse effects (AEs) of MSD were fewer (p < 0.00001; OR = 0.08; 95% CI [0.05, 0.16]). MSD are effective in the treatment of gouty arthritis through anti-inflammation and lowering urate. However, the efficacy of MSD should be estimated with more RCTs.

Perioperative risk factors and cumulative duration of "triple-low" state associated with worse 30-day mortality of cardiac valvular surgery.

ABSRACT: Hospital stay and mortality in high-risk patients after noncardiac surgery has been associated with a triple low anesthesia. However, the association between anesthesia-related factors and perioperative outcome after cardiac surgery remains unclear.We tested the effect of a novel triple low state: low mean arterial pressure (MAP) <65 mmHg and low bispectral index (BIS) <45 during a low target effect-site concentration (Ce) <1.5 µg ml-1 of propofol anesthesia on postoperative duration of hospitalization and 30-day mortality in cardiac valvular patients. In this prospective observational study, univariable and multivariable logistic regression analyses were used to determine whether perioperative factors, in particular, cumulative duration of triple low state were independently associated with duration of hospitalization and 30-day mortality among patients who underwent elective valvular replacement. 489 patients were included in the final analysis. After adjusting for related covariates, cumulative duration of the triple-low state was not associated with prolonged hospitalization (multivariable odds ratio: 1.007; 95 % confidence interval 0.997-1.017; P = 0.564), but was a significant predictor of 30-day mortality (multivariable odds ratio: 1.016; 95 % confidence interval 1.002-1.031; P = 0.030). Compared to a triple-low duration of <15 min, a duration >60 min increased the 30-day mortality rate by 8 times. After adjusting for patient- and procedure-related characteristics, the cumulative duration of a triple-low state (intraoperative low MAP, low BIS, and low Ce) was associated with poorer 30-day mortality, but not with prolonged duration of hospital stay.The mortality risk was even greater when a cumulative time >60 min.

Effects of Berberine on NLRP3 and IL-1ß Expressions in Monocytic THP-1 Cells with Monosodium Urate Crystals-Induced Inflammation.

Background. Urate crystals-induced inflammation is a critical factor during the initiation of gouty arthritis. Berberine is well known for its anti-inflammatory activity. However, the underlying effects of berberine on monosodium urate crystals-induced inflammation remain obscure. Objectives. This study is set to explore the protective effect and mechanism of berberine on monosodium urate crystals-induced inflammation in human monocytic THP-1 cells. Methods. The mRNA levels of NLRP3 and IL-1ß were measured by Real-Time PCR, and the protein levels of NLRP3 and IL-1ß were determined by ELISA, Western blot, and immunofluorescence. Results. The NLRP3 and IL-1ß expressions were significantly increased in model group compared to that in normal group (P < 0.05). Meanwhile, there was significant reduction in the expressions of NLRP3 and IL-1ß mRNA in groups 6.25 µM berberine and 25 µM berberine when compared with model group (P < 0.05). Conclusions. Therefore, berberine alleviates monosodium urate crystals-induced inflammation by downregulating NLRP3 and IL-1ß expressions. The regulatory effects of berberine may be related to the inactivation of NLRP3 inflammasome.

Effects of Wutou Decoction on DNA Methylation and Histone Modifications in Rats with Collagen-Induced Arthritis.

Background. Wutou decoction (WTD) has been wildly applied in the treatment of rheumatoid arthritis and experimental arthritis in rats for many years. Epigenetic deregulation is associated with the aetiology of rheumatoid arthritis; however, the effects of WTD on epigenetic changes are unclear. This study is set to explore the effects of WTD on DNA methylation and histone modifications in rats with collagen-induced arthritis (CIA). Methods. The CIA model was established by the stimulation of collagen and adjuvant. The knee synovium was stained with hematoxylin and eosin. The DNA methyltransferase 1 (DNMT1) and methylated CpG binding domain 2 (MBD2) expression of peripheral blood mononuclear cells (PBMCs) were determined by Real-Time PCR. The global DNA histone H3-K4/H3-K27 methylation and total histones H3 and H4 acetylation of PBMCs were detected. Results. Our data demonstrated that the DNMT1 mRNA expression was significantly lowered in group WTD compared to that in group CIA (P < 0.05). The DNA methylation level was significantly reduced in group WTD compared to that in group CIA (P < 0.05). Moreover, H3 acetylation of PBMCs was overexpressed in WTD compared with CIA (P < 0.05). Conclusions. WTD may modulate DNA methylation and histone modifications, functioning as anti-inflammatory potential.

A Systematic and Narrative Review of Acupuncture Point Application Therapies in the Treatment of Allergic Rhinitis and Asthma during Dog Days.

Acupuncture point application therapies, including San-Fu-Tie and San-Fu-Jiu, have been widely employed to treat diseases with attacks in winter during dog days in China. The therapies combine Chinese herbal medicine and acupuncture points with the nature. However, the previous studies were reported to be unsystematic and incomplete. To develop a more comprehensive understanding of the effects of acupuncture point application therapies on allergic rhinitis and asthma, a systematic review of the literature up to 2015 was conducted. After filtering, eighteen randomized controlled trials (RCTs) involving 1,785 subjects were included. This systematic and narrative review shows that acupuncture point application therapies have been extensively applied in the treatment of allergic rhinitis and asthma with advantages of favorable treatment effect, convenient operation, receiving patients' good acceptability and compliance, and few side effects. Meanwhile, the study elaborated the operating process of San-Fu-Tie and San-Fu-Jiu in detail. The review may provide a reference for clinical application in future. However, the efficacy, safety, and mechanisms of San-Fu-Tie and San-Fu-Jiu in treating the above diseases need to be validated by more well-designed and fully powered RCTs in a larger population of patients.
