Efficacy and safety of Jiawei Simiao powder combined with celecoxib for acute gouty arthritis:A meta-analysis

Objective:To evaluate the efficacy and safety of Jiawei Simiao powder(JWSMP)combined with celecoxib for the treatment of acute gouty arthritis by conducting a meta-analysis of randomized controlled trials(RCTs).Methods: The Chinese National Knowledge Infrastructure Databases,Chinese Scientific Journal Database,Wanfang,Cochrane Library,EMBASE,PubMed,and Web of Science databases were searched from inception until December 2023.Continuous variables were analyzed using the mean difference(MD)for analysis,and dichotomous variables were used as risk ratios.Data with similar characteristics were pooled for meta-analysis,and heterogeneity was assessed using I2.The Cochrane Handbook was used to assess the risk of bias and quality.RevMan 5.3 software was used to perform the meta-analysis.Results: Thirteen RCTs involving 1007 patients were included in the study.The quality of the included studies was low(unclear randomization processes and insufficient blinding reporting).The group receiving JWSMP combined with celecoxib showed significantly lower levels of serum uric acid(SUA,MD=−66.32,95%confidence interval(CI):−80.97 to−51.67,P<.001),erythrocyte sedimentation rate(ESR,MD=−6.05,95%CI:−8.29 to−3.82,P<.001),C-reactive protein(CRP,MD=−7.39,95%CI:−11.15,−3.63,P<.001),and joint pain score(VAS score,MD=−2.14,95%CI:−2.4 to−1.88,P<.001)compared to celecoxib alone.Additionally,the JWSMP combined group had a higher total effective rate(risk ratio=1.22,95%CI:1.14 to 1.29,P<.001)and fewer adverse compared to celecoxib alone.Conclusions: JWSMP combined with celecoxib is more effective than celecoxib alone in improving the total efficacy rate,alleviating joint pain,and improving SUA,ESR,and CRP levels.JWSMP also reduced the occurrence of adverse events caused by celecoxib.However,the quality of the included studies was low,highlighting the need for further high-quality research with larger sample sizes and robust methodologies,such as double-blind randomization,to confirm these findings.

Simiao Wan alleviates obesity-associated insulin resistance via PKCε/IRS-1/PI3K/Akt signaling pathway based on network pharmacology analysis and experimental validation

Background:The purpose of the study was to investigatethe active ingredients and potential biochemicalmechanisms of Simiao Wan(SMW)in obesity-associated insulin resistance.Methods:An integrated network pharmacology method to screen the active compoundsand candidate targets,construct the protein-protein-interaction network,and ingredients-targets-pathways network was constructed for topological analysis to identify core targets and main ingredients.To find the possible signaling pathways,enrichment analysis was performed.Further,a model of insulin resistance in HL-7702 cells was established to verify the impact of SMW and the regulatory processes.Results:An overall of 63 active components and 151 candidate targets were obtained,in which flavonoids were the main ingredients.Enrichment analysis indicated that the PI3K-Akt signaling pathway was the potential pathway regulated by SMW in obesity-associated insulin resistance treatment.The result showed that SMW could significantly ameliorate insulin sensitivity,increase glucose synthesis and glucose utilization and reduce intracellular lipids accumulation in hepatocytes.Also,SMW inhibited diacylglycerols accumulation-induced PKCεactivity and decreased its translocation to the membrane.Conclusion:SMW ameliorated obesity-associated insulin resistance through PKCε/IRS-1/PI3K/Akt signaling axis in hepatocytes,providing a new strategy for metabolic disease treatment.

Treatment of 60 Cases of Gouty Arthritis with Modified Simiao Tang

Objective:To observe the clinical effect of a modified Simiao Tang (加味四妙汤 Modified Decoction of Four Wonderful Drugs) for gouty arthritis and its influence on uric acid in blood. Methods: 120 cases of gouty arthritis were randomly divided into the treatment group and control group with 60 cases in each group. Modified Simiao Tang (MST) was orally administered to the patients in the treatment group and allopurinol tablet was orally administered to the patients in the control group. The clinical effects of two groups were evaluated after one-week treatment and uric acid (UA) and C-reactive protein (CRP) levels in blood were determined after 1-month treatment. Results: The total effective rate in the treatment group was significantly higher than in the control group, 86.7% vs. 68.3% (P< 0.01). And the treatment group was also significantly better than the control group in decreasing UA and CRP (P<0.05 or P<0.01). Conclusions: MST can significantly improve the symptoms and signs of gouty arthritis and decrease the levels of UA and CRP. It is good for gouty arthritis.

Effect of the degree of milling on the physicochemical properties,pasting properties and in vitro digestibility of Simiao rice

Simiao rice is a variety of long-grain Indica rice popular in South China.However,researches on the milling technology of Simiao rice are limited.The effect of different degrees of milling(DOMs)of Simiao rice(0-12%)were evaluated in terms of the physicochemical properties and in vitro starch digestibility of the rice.The results showed that,as the DOM increased from 0 to 12%,the head rice yield(HRY)and the content of protein,lipid,dietary fiber,vitamin B1,vitamin E and niacin nonlinearly decreased,while the content of total starch and amylose and paste viscosity parameters nonlinearly increased.The differences in chemical constituents between the brown and milled Simiao rice with different DOMs lead to the variation in their pasting properties and in vitro digestibility.Because of lower content of slowly digestible starch(SDS)and resistant starch(RS),milled Simiao rice exhibited greater digestibility and a higher estimated glycaemic index(EGI).The EGI of Simiao rice ranged from 77.98 to 85.55,and remained almost constant(approximately 84)when the DOM was above 4%.Correlation analysis indicated that the EGI had strong negative correlations with lipid,protein,dietary fiber and RS,but a positive correlation with amylose.These results provide theoretical guidance for the production of Simiao rice with desired physicochemical properties and digestibility by adjusting the DOM.
