目的:研究中药当归芍药散对外周血T淋巴细胞转录因子GATA-3和T-bet mRNA表达的影响,初步探讨其用于治疗不明原因反复自然流产的可能性。方法:体外分离提取11例志愿者外周血单核细胞,在含有或不含当归芍药散的培养液中培养24h,用实时定量PCR技术检测GATA-3和T-bet mRNA的表达。结果:用10 μg/mL浓度当归芍药散处理后,单核细胞中GATA-3 mRNA的含量与对照组比较显著增高(P<0.05)。当归芍药散处理细胞后,T-bet mRNA的表达水平呈降低趋势,当浓度为100 μg/mL时,与对照组比较有显著性差异(P<0.05)。结论:当归芍药散可上调转录因子GATA-3 mRNA的表达或下调T-bet mRNA的表达,从而可能通过调节Th2/Th1平衡向Th2偏移、对于Th1反应异常增强的不明原因反复自然流产有一定的治疗潜能。
Objective To evaluate the effectiveness and safety of Chinese angelica decoction (CAD) versus conventional treatment (CT) for chronic urticaria (CU). Methods Systematic searches were conducted in PubMed, The Cochrane Library, SCI, EMbase, VIP, CNKI and CBM to collect randomized controlled trials (RCTs) on CAD treating CU from inception to July 2011. Two reviewers independently screened articles according to the inclusion and exclusion criteria, extracted data and evaluated the quality of the included studies. Then meta-analysis was performed using RevMan 5.0.2. Results A total of 11 RCTs involving 1081 patients were included. The results of meta-analysis demonstrated that compared with the CT group (antihistamine therapy), CAD seemed higher in the cure rate (OR=2.36, 95%CI 1.80 to 3.10, I2=22%, Plt;0.000 01), improvement rate (OR=4.56, 95%CI 2.65 to 7.87, I2=0%, Plt;0.000 01), and lower in the relapse rate at the third month after the treatment (OR=0.43, 95%CI 0.22 to 0.82, I2=0%, P=0.01). No study reported the quality of life and severe adverse reactions after CAD treatment. Conclusion Current evidence shows CAD may be superior to CT in treating CU patients. However, due to lack of enough high-quality studies, CAD has to be further studied by conducting more strictly-designed, multicenter, large-scale and double-blind RCTs.
Objective To study the regulative effect of angelica sinensis on cellular immune function in perioperative patients with obstructive jaundice. Methods Fourteen patients with obstructive jaundice were injected with angelica before and after operation for 14 days. The activity of IL-2 and the expression of IL-2R in lymphocytes in peripheral blood were measured, respectively. Results The activity of IL-2 and the expression of IL-2R decreased significantly in patients with obstructive jaundice (P<0.01). The activity of IL-2 and the expression of IL-2R in peripheral blood lymphocyte increased significantly before and after operations (after treatment using angelica) (P<0.01), though there was a little decrease after operation but they were still higher than that befor using angelica.Conclusion It maybe useful to use angelica to improve the cellular immune function in patients with obstructive jaundice.
