| 摘要 目的： 通过观察血必净干预对慢性阻塞性肺疾病 （COPD ） 大鼠体内炎症因子的影响， 探讨血必净治疗 COPD 的机制。方法：
36 只 Wistar 雄性大鼠随机分为对照组、 COPD 型组 （ 简称型组 ） 、 血必净干预组 （简称干预组）， 每组 12 只。 采用香烟烟雾暴露
加气管内滴注脂多糖法建立 COPD 大鼠型。 造模时间共 30 天， 其中干预组在后 15 天给予血必净 4 ml/Kg 体重尾静脉注射。 分

大鼠血清及肺泡灌洗液中炎症因子 TNF-琢、 IL-6、 IL-8 的浓度均显著增高， 血必净干预能显著下调上述关键致炎因子的表达， 并与
其临床症状、 肺功能、 病理学改变相印证。因此， 我们推测： 血必净可能通过下调 COPD 炎症时 TNF-α、 IL-6、 IL-8 等关键致炎因子
的表达， 进一步抑制气道炎症的级联效应来发挥其强大的抗炎作用。 |

| ABSTRACT Objective:To explore the mechanism of Xuebijing treatment by observing the effect on inflammatory cytokine in rat
with chronic obstructive pulmonary disease (COPD) after Xuebijing dealing.Methods: Tirty-six Wister rats were divided intoa control
group,a COPD group and a dealing group at random. The COPD rat model was established by intratracheal instillation of
lipopolysaccharide (LPS) twice and exposuring to cigarette smoke daily for 30 days, and the dealing group was given Xuebijing injection
for dose of 4 mL/Kg weight every day in last 15 days. The spirometry was conducted and the pathological changes were observed after
the model was established. The concentration of tumor necrosis factor (TNF-α), interleukin-6 (IL-6), interleukin-8 (IL-8) in serum and
bronchoalveolar lavage fluid was detected by enzyme-linked immunosorbent assay.Results: Significant decrease of FEV0.3/FVC[(57.8±
5.6) %] and dynamic compliance of lung (Cdyn) [(0.098 ± 0.006) cmH2 O · mL
-1
· s

] , and increase of airway resistance (RI) [(0.802 ±
0.070) mL/cmH2 O] were found in the COPD group compared with the control group [(81.4± 3.1) %, (0.195± 0.012) cmH2 O · mL

,
(0.224 ± 0.069) mL/cmH2O] (t=-13.940, -15.165, -22.389,P＜ 0.01). Significant increase of FEV0.3/FVC [(67.2 ± 3.2) %] and dynamic
compliance of lung (Cdyn) [(0.142± 0.024) cmH2 O · mL · s
-1
], and decrease of airway resistance (RI) [(0.475± 0.050) mL/cmH2O] were
found in the dealing group compared with the COPD group (t=-5.552, -6.927, -12.658,P＜ 0.01). Conclusion:The concentration of TNF-α, IL-6, IL-8
[(27.8 ± 7.4) pg/mL, (340.0 ± 79.6) pg/mL, (209.9 ± 82.1) pg/mL, (337.3 ± 96.4) pg/mL, (37.7 ± 11.4) pg/mL, (69.6 ± 18.9) pg/mL]in
serum and bronchoalveolar lavage fluid of the COPD rats were found to significantly increase compared with the control rats(t=-12.466,
-19.648, -11.749, -16.364, 12.550, 14.834,P＜ 0.01), while the concentration of TNF-α, IL-6, IL-8 [(9.6± 5. 6) pg/mL, (45.6± 22.9) pg/mL,(36.3± 17.9) pg/mL, (42.9± 20.5) pg/mL, (10.3± 5.6) pg/mL, (15.7± 8.0)pg/mL] in the dealing rats were found to singificantly decrease
compared with the COPD rats (t=-9.367, -17.390, -10.106, -14.631, 10.475, 12.772,P＜ 0.01). The concentration of TNF-α,
IL-6, IL-8 in serum and bronchoalveolar lavage fluid of the COPD rats were found to significantly increase, which can significantly
decrease by Xuebijing treatment. Those changes confirmed with their clinical symptoms, lung function and pathological changes. So we
speculated that Xuebijing may downgrade expression of key proinflammatory cytokines in COPD inflammatory, including TNF-α, IL-6
and IL-8, further inhibit the cascade effect of airway inflammation, by which it played strong anti-inflammatory effects. |
