RESUMEN
ObjectiveTo explore the clinical efficacy of Gouteng prescription in treating the patients with primary hypertension with anxiety disorder due to yang hyperactivity and heat toxin and the impact of the formula on the balance of inflammatory cytokines. MethodA total of 98 patients diagnosed with primary hypertension and anxiety disorder were randomized into control and observation groups. On the basis of conventional western medicine treatment for hypertension， the control group （47 patients） was treated with Shugan Jieyu capsules for 8 weeks， while the treatment group （51 patients） with Gouteng prescription for 8 weeks. The two groups were compared in terms of the blood pressure level， 24-hour blood pressure variability， Hamilton anxiety scale （HAMA） score， Pittsburgh sleep quality index （PSQI） score， quality of life （SF-36 scale） score， traditional Chinese medicine （TCM） syndrome score and efficacy， incidence of adverse reactions， and the levels of interleukin （IL）-1β， IL-6， IL-10， and IL-4 in the serum of peripheral blood. ResultThe final trial was completed with 95 patients， including 46 in the control group and 49 in the observation group. The treatment in both groups lowered the blood pressure and blood pressure variability （P<0.05， P<0.01）. The observation group outperformed the control group in recovering the systolic blood pressure （SBP）， 24-hour mean systolic blood pressure （24 h SBP）， 24-hour systolic blood pressure variability （24 h SBPV）， and 24-hour diastolic blood pressure variability （24 h DBPV） （P<0.05）. After treatment， the HAMA and PSQI scores in both groups decreased （P<0.05， P<0.01）， and the observation group had lower HAMA and PSQI scores than the control group （P<0.05）. Compared with those before treatment， the SF-36 scores in both groups increased （P<0.05， P<0.01）. After treatment， the observation group had higher scores of physiological function （PF）， bodily pain （BP）， social function （SF）， role-emotional （RE）， and mental health （MH） indicators than the control group （P<0.05）. After treatment， the TCM syndrome scores in both groups decreased （P<0.05， P<0.01）， and the observation group had lower score than the control group （P<0.05）. The total response rate regarding TCM syndrome in the observation group was 85.71% （42/49）， which was higher than that （63.04%， 29/46） in the control group （χ2=6.621， P<0.05）. The treatment in both groups lowered the levels of pro-inflammatory cytokines （IL-1β， IL-6） and elevated the levels of anti-inflammatory cytokines （IL-10， IL-4） （P<0.05， P<0.01）， and the changes were more obvious in the observation group than in the control group （P<0.05）. There were no adverse events during the research process. ConclusionGouteng prescription can recover the blood pressure level， reduce blood pressure variability， suppress anxiety state， improve sleep and quality of life， decrease TCM syndrome score， increase total response rate， lower serum IL-1β and IL-6 levels， and elevate serum IL-10 and IL-4 levels in the patients with primary hypertension complicated with anxiety disorder due to yang hyperactivity and heat toxin. It may exert the effects by regulating the balance of pro-inflammatory and anti-inflammatory cytokines.
RESUMEN
Objective To study the antitumor effects of dendritic cell vaccine induced by astragalus polysaccha?rides on S180 tumor-bearing mice, and its possible mechanism. Methods Dendritic cells derived from mouse bone marrow were induced maturation by astragalus polysaccharides and loaded with S180 tumor antigen to prepare tumor vaccine. Tu?mor-bearing mice were divided into four groups and treated on day-5 and day-10 respectively. Group A was injected with NS, Group B with CTX (50 mg/kg), Group C with dendritic cells induced by astragalus polysaccharides and Group D with dendritic cells induced by tumor necrosis factor (TNF)-α. After 12 days of tumor-bearing, the animals were killed. The sub?cutaneous sarcoma, thymus and spleen were separated and weighted. The inhibitory rate, thymus index and spleen index were then calculated. ELISA assay was used to detect the levels of interleukin (IL)-4, interferon (IFN)-γin serum of tumor bearing mice. Results The tumor inhibition rate was higher in astragalus polysaccharide group and cytokine group than that of CTX group (64.25%, 64.10%vs 35.11%). The thymus index was higher in astragalus polysaccharide group and cyto?kine group than that of CTX group (1.69 ± 0.26, 1.74 ± 0.38 vs 1.45 ± 0.22). The spleen index was higher in astragalus poly?saccharide group and cytokine group than that of CTX group (5.44 ± 0.76, 5.31 ± 0.81 vs 3.54 ± 0.52). The level of IL-4 was lower in astragalus polysaccharide group and cytokine group than that of CTX group (15.66±2.57, 14.72 ± 4.84 vs 23.95 ± 6.07). The level of IFN-γwas higher in astragalus polysaccharide group and cytokine group than that of CTX group (16.54 ± 3.71, 17.20 ± 2.03 vs 10.37 ± 2.19). All the differences were statistically significant (P<0.05). Conclusion Dendritic cell vaccine induced by astragalus polysaccharides can effectively inhibit tumor growth. Its mechanism may be associated with the promotion spleen index and thymus index of S180 tumor-bearing mice, the effective correction of Th1/Th2 imbalance in?duced by tumor, and the enhancement of antitumor immune responses.
RESUMEN
Purpose To observe the effect of paeonol on inflammatory factors after focal cerebral ischemiareperfusion injury in rats and its possible mechanism of paeonol.Methods Focal cerebral ischemic model was established by MCAO in rats.After 2 hours of cerebral ischemia and 22 hours of reperfusion,the expression of TNF-α and IL-1β in brain was determined by immunohistochemistry.The content of TNF-α and IL-1β in serum was measured by ELISA.Results Compared with model group,the levels of TNF-α and IL-1β in brain and serum in rats in the paeonol groups were obviously decreased.Conclusion Paeonol could relieve brain damage induced by focal cerebral ischemia-reperfusion,which may be related to inhibiting the production of inflammatory factors.
