A multi-center, randomized, double-blind, double-simulation, positive-controlled and parallel trial was conducted. A total of 136 patients exhibiting clinical symptoms of gingivitis were enrolled. The subjects were randomly assigned to two groups： test group （n=67）, in which rabdosia rubescens drop pill （960 mg） and 4 tablets of simulation agent of rabdosia rubescen were orally given to the subjects three times a day for 5 days; and control group （n=69）, in which the subjects were administered the tablets of rabdosia rubescens （1000 mg） and 24 drop pills of simulation agent of rabdosia rubescens thrice daily for 5 days. The experimental protocols and diagnostic criteria were established by expert panel prior to the experiment. The clinical symptoms were graded according to the severity of the disease and quantified. The total scores and scores for each clinical symptom of gingivitis were assessed at baseline and on the 6th day post-treatment. The therapeutic efficacy was compared between the two groups and in each group itself before and after the treatment. The results showed that in the two groups, the subjects who were given rabdosia rubescens, drop pill or tablet, had a decrease in total scores and scores for each clinical symptom when compared with those before treatment （P〈0.01）. There was significant difference in the therapeutic efficacy between the test group and the control group with the efficacy rate being 92.54% and 79.71% respectively （P〈0.05）. It was concluded that rabdosia rubescens showed great promise in treating gingivitis. And rabdosia rubescens drop pill was more efficacious than rabdosia rubescens tablet.展开更多

The subjects were divided into control group (n=35) and treatment group (n=35) randomly. Patients in the control group were treated with new assistant chemotherapy, while those who were in the treatment group were treated with rabdosia rubescens combined with new assistant chemotherapy. The two groups of patients were treated for 3 periods. The serum CA199, CEA, CA15-3 levels and peripheral blood CD4+, CD8+, CD4+/CD8+ cells of the two groups before and after treatment were compared.Results:There were no significantly differences among the serum CA199, CEA, CA15-3 levels and peripheral blood CD4+, CD8+, CD4+/CD8+ cells of the two groups before treatment. The serum CA199, CEA and CA15-3 levels of the two groups after treatment were significantly lower than those before treatment, besides, the serum CA199, CEA and CA15-3 levels of the treatment group were significantly lower than those of the control group. The peripheral blood CD4+, CD4+/CD8+ cells of the control group after treatment were significantly lower than before treatment, and the peripheral blood CD4+, CD4+/CD8+ cells of the treatment group after treatment were significantly higher than those of the control group.Conclusion:Rabdosia rubescens combined with new assistant chemotherapycan can significantly reduce the serum CA199, CEA and CA15-3 levels, and improve peripheral blood CD4+, CD8+, CD4+/CD8+ levels of patients with breast cancer. It is worthy of clinical application.展开更多
