Conclusion Compound Uncaria Hypotensive Tablets can reduce the blood pressure of SHR, reduce inflammation reaction, and regulate vascular remodeling, which mechanism may be related to down-regulation of expressions of MCP-1 and MMP-9 in SHR aortic endothelial cells.

Objective To investigate the effect of Xuebijing injection on inflammatory factors in patients with Stanford B aortic dissection (AD) after endovascular repair and approach its clinical significance.Methods Sixty patients with Stanford type B AD for endovascular repair admitted to the Department of Cardiothoracic Surgery of the First Affiliated Hospital of Hunan University of Traditional Chinese Medicine (TCM) from January 2014 to June 2016 were enrolled, and they were divided into a Xuebijing group and a control group according to the random number table method, 30 cases in each group. The patients of Xuebijing group received 100 mL Xuebijing injection+ 50 mL normal saline intravenous drip during operation, while the patients of control group received an equal volume of normal saline, 2 times a day in both groups for consecutive 3 days. Peripheral venous blood was collected before and after treatment for 1, 2, and 3 days, and the levels of C-reactive protein (CRP), tumor necrosis factor-α(TNF-α), interleukin-6 (IL-6) were measured by enzyme-linked immunosorbent assay (ELISA), and the prognosis of the two groups was observed.Results With the prolongation of time, the postoperative levels of CRP, TNF-α and IL-6 in the two groups showed a tendency of first increase and then decrease compared with the preoperative levels, the above indexes of the two groups were all significantly higher, CRP (mg/L) and TNF-α (ng/L) peaked on the 2nd day postoperatively (control group: CRP was 146.34±13.92 and TNF-α was 72.22±7.63, Xuebijing group: CRP was 114.92±9.89 and TNF-α was 53.44±6.80, allP < 0.05), however, IL-6 (ng/L) peaked on the 1st day postoperatively (control group: 146.08±10.29, Xuebijing group: 117.88±8.84), then decreased, all reached the valley on the 3rd day postoperatively (control group: CRP, TNF-α, IL-6 was 112.59±8.54, 43.73±4.10, 70.03±4.66 respectively, Xuebijing group CRP, TNF-α, IL-6 was 87.75±7.67, 39.43±4.63, 56.65±3.27, respectively), and at the same time point, the level of CRP, TNF-α, IL-6 in the Xuebijing group were significant lower than those in the control group, the change were the most significant on 3 days after operation [CRP (mg/L): 87.75±7.67 vs. 112.59±8.54, TNF-α (ng/L): 39.43±4.63 vs. 43.73±4.10, IL-6 (ng/L): 56.65±3.27 vs. 70.03±4.66, P < 0.05]. There were no serious complications such as renal failure, severe hypoxemia, infection, paraplegia, stent shift and so on, no hospital death occurred and all patients were discharged in rehabilitative condition. Conclusions Endovascular repair in patients with Stanford type BAD may activate an inflammatory response inducing the release of a large amount of inflammatory factors during the early postoperative period, Xuebijing injection can inhibit the inflammatory reaction and prevent the occurrence of postoperative complications.

AIM To observe the changes of plasma neuropeptide Y (NPY) levels in patients with essential hypertension(EH) taking Compound Qishao Jiangya Tablets (Radixet Rhizoma Notoginseng, Radix Paeoniae Alba, Rhizoma Gastrodiae, etc) and to investigate the significance of NPY in the pathogenesis of hypertension and the relationship between NPY and platelet disnormal function. METHODS The plasma NPY concentrations of 60 patients with EH and 20 normal ones were determined by radioimmunoassay, at the same time detected platelet aggregation rate and fibrinogen were detected. RESULTS The levels of plasma NPY in patients with EH were higher than that in normal control group. The NPY levels, the platelet aggregation rate, fibrinogen in the three periods of hypertension (period Ⅰ,Ⅱ, Ⅲ) were all significantly different and were increased with the severity of hypertension. CONCLUSION NPY may participate in the pathophysiological course of hypertension, and the plasma NPY, the platelet aggregation rate of the patients with EH were correlative. The plasma NPY should be dynamscally monitored in order to determine the disease degree. During the treatment for EH attention should be taken to decrease the platelet aggregation rate.

AIM: To study the effect of IL-12 on T lymphocytes apoptosis, the expression of Fas/FasL and TNFR/TNF?. METHODS: Terminal dUTP nick end labeling(TUNEL) and Annexin V assay were used. Anti-TNFR were labeled with FITC, anti-CD95 was labeled with PE and Anti-FasL with biotin. Three kinds of T cells (HTB176,TIB152 and human normal T cells) were analysed through flow cytometry. RESULTS: At 1st hour after being treated with IL-12, the expression of FasL protein and FasL mRNA in HTB176 and TIB152 began to increase and reached peak value in 24 hours. In the normal T cells, FasL just began to increase in 1 hour and maintained stability in 6, 12 and 24 hours through the later experiment period. All three kinds of T cells displayed no change in the expression of CD95 and TNFR/TNF? under the stimulation of IL-12. CONCLUSION: Expression of such apoptosis regulating factors were different in the apoptosis of T cells induced by IL-12.
