ABSTRACT
Objective to investigate the efficacy of moxibustion treatment to rheumatoid arthritis(RA) patients and the impact to blood levels of rheumatoid factor(RF) ,C reactive protein(CRP) ,and interleukin-6(IL-6) .Methods RA patients were divided in-to treatment group and comfort group .The two groups were treated by moxibustion and sham-moxibustion for 2 courses ,respec-tievely .Results Overall clinical efficacy rate was higher in treatment group than in comfort group(P<0 .01) .The arthralgia ,ar-throcele ,tenderness and its degrees ,and morning stiffness time were significant improved in both groups(P<0 .05) ,and the indexes were better in treatment group than comfort group(P<0 .05) .The blood levels of RF ,IL-6 and CRP were reduced after treatment in both groups(P<0 .05) ,and which of treatment group reduced more than those of comfort group(P<0 .05) .Conclusion Moxi-bustion treatment can significantly improve clinical outcomes of RA and markedly reduce the blood levels of RF ,IL-6 and CRP of RA patients .
ABSTRACT
Objective:To prepare dexketoprofen enteric-coated pellets and explore the drug release rate respectively in 0. 1 mol· L-1 hydrochloric acid and phosphate buffered saline(PBS,pH 6. 8). Methods:Dexketoprofen enteric-coated pellets were prepared u-sing fluid-bed coating technology, the blank sugar pellets were coated with drug layer, isolation layer and enteric layer in order. Drug-loading rate as the index, the optimal concentrations of HPMC and drug were screened. Such indicators as adhesion, pellet uniform and surface color as the indices, the coating process was optimized by orthogonal experiment. Drug release in PBS of the enteric-coated pel-lets and the common enteric-coated tablets were compared. Results:The prepared pellets showed the properties of uniform drug load-ing, high drug-loading rate, complete round shape and lustrous appearance. The concentration of HPMC and drug was 5% and 15%, respectively. The optimal coating process was as follows:the material temperature was 36℃, the atomization pressure was 1. 0 bar and the airbrush rate was 0. 8 ml·min-1 . The drug release of the pellets in hydrochloric acid was below 10% in 2 hours, while the release in PBS was greater than that of the common enteric-coated tablets. Conclusion: The prepared enteric-coated pellets are feasible in technology, and exhibit satisfactory acid endurance and drug release in vitro.
