Objective To investigate the differences and significance of blood levels of T helper 17 (Th17) cell and interleukin17 (IL-17) between peripheral and culprit vessels in patients with acute coronary syndrome.Methods A total of 76 patients recruited in 2012 were divided into three groups according to the coronary angiography and clinical manifestations:acute coronary syndrome,stable angina and control groups.The blood samples were taken from cubital vein and culprit coronary artery after coronary angiography.The percentage of Th17s among CD4+ T cells was detected by flow cytometric analysis and the IL-t7 levels were measured by enzyme-linked immunosorbent assay.Results There was no significant difference in the percentages of Th17 cells between peripheral blood and culprit artery blood [(3.18 ± 0.29) ％ vs.(3.17 ±0.30)％,(P =0.919)];but the perecentages of Th17 in peripheral blood were found to be significantly higher in patients with acute coronary syndrome (3.18 ± 0.29)％ than those with stable angina (1.32 ± 0.31) ％ and those without coronary heart disease (1.28 ± 0.33) ％,(P ＜ 0.01).There was no significant difference in the level of IL-17 between peripheral blood and culprit artery blood [(81.23 ± 18.63) vs.(82.37 ±20.51) pg/mL,P =0.573];but the level of IL-17 in peripheral blood was also significantly higher in patients with acute coronary syndrome than those with stable angina and those without coronary heart disease [(81.23 ± 18.63) vs.(25.96 ± 14.58) pg/mL or (23.75 ± 13.64) pg/mL,P ＜0.01].Conclution There were no significant differences in percentage of Th17 cell among CD4 + T cells and levels of IL-17 in blood between peripheral and culprit vessels in patients with acute coronary syndrome.The percentage of Th17 among CD4 + T cells and the levels of IL-17 in blood increase in patients with acute coronary syndrome suggesting a potential role of Th17 and IL-17 in the development and instability of the atheroma.

Objective:To observe the clinical effect of modified Shishi Niubangzi Decoction combined with strengthening muscle-waist exercise on lumbar disc herniation (LDH).Methods:Randomized controlled trial. A total of 60 patients with LDH admitted to the Pinggu Hospital, Beijing Traditional Chinese Medicine Hospital, were enrolled as the research objects between September 2020 and September 2021. According to the random number table, they were randomly divided into the treatment group and control group, 30 in each group. Both groups were given routine basic treatments (strengthening tendons-waist exercise and three-position six-step manipulation). On this basis, the treatment group was treated with modified Shishi Niubangzi Decoction, while the control group was treated with non-steroidal anti-inflammatory drugs (ibuprofen codeine sustained-release tablets). Both groups were treated for 4 weeks. The responsive rates, back pain intensity, leg pain and numbness by Visual Analogue Scale (VAS) and lumbar function by Oswestry Disability Index (ODI), and Japanese Orthopaedic Association (JOA) were compared between the two groups.Results:The response rate of treatment group was significantly higher than that of control group (93.3% vs. 73.3%; χ2=4.32, P=0.038). After treatment, scores of JOA (subjective symptoms, signs, activities of daily living) in the treatment group were significantly higher than those in the control group ( t=3.86, 2.71, 2.21, P<0.05). After treatment, scores of back pain (2.12±0.21 vs. 3.02±0.32, t=12.88), leg pain (2.04±0.64 vs. 2.64±0.66, t=3.58), lower limb numbness (1.75±0.24 vs. 2.41±0.70, t=4.89) in the treatment group were significantly lower than those in the control group ( P<0.01). At 1 week and 1 month after treatment, ODI scores in treatment group were significantly lower than those in control group ( t=10.22, 5.59; P<0.05). Conclusion:The modified Shishi Niubangzi Decoction combined with strengthening tendons-waist exercise can improve responsive rates, improve lumbar pain and function in LDH patients.
