2
S的供体，检测H
2
S对血管紧张素Ⅱ（Ang Ⅱ）诱导心肌成纤维细胞增殖、羟脯氨酸含量以及去乙酰化酶3（SIRT3）蛋白表达的影响。用干扰RNA技术下调SIRT3表达后，观察H

结果
2
H
2
S可抑制Ang Ⅱ诱导的心肌成纤维细胞增殖，降低羟脯氨酸含量，增强SIRT3蛋白表达（

2
H
2
S依赖增加SIRT3表达来抑制Ang Ⅱ诱导的心肌成纤维细胞增殖。
Abstract
OBJECTIVE
2
To investigate the inhibitory effect and the possible mechanism of hydrogen sulfide （H
2
S） on the proliferation of cardiac fibroblasts.
METHODS
2
The heart of neonatal SD rats was collected， and cardiac fibroblasts were separated with differential centrifugation. Using sodium hydrosulfide as the donor of H
2
S， the effects of H
2
S on the proliferation of cardiac fibroblasts induced by angiotensin Ⅱ （Ang Ⅱ）， hydroxyproline content and the expression of sirtuin 3 （SIRT3） protein were detected. After SIRT3 knockdown with siRNA technology， the effects of H
2
S on the proliferation of cardiac fibroblasts induced by Ang Ⅱ， hydroxyproline content， the expressions of collagen Ⅰ （Col Ⅰ）， collagen Ⅲ （Col Ⅲ ） and optic atrophy protein 1 （OPA1） were detected.
RESULTS
2
H
2
S could inhibit the proliferation of Ang Ⅱ-induced cardiac fibroblasts， reduce the content of hydroxyproline and increase the expression of SIRT3 （
P
＜0.05）. After down-regulating the expression of SIRT3 with siRNA technology， the inhibition of H
2
S on the proliferation of Ang Ⅱ-induced cardiac fibroblasts and the reduction of hydroxyproline content were both inhibited， and the effect of H
2
S on reducing the expression of Col Ⅰ and Col Ⅲ and enhancing the expression of OPA1 was also significantly weakened.
CONCLUSIONS
2
H
2
S inhibits the proliferation of Ang Ⅱ-induced cardiac fibroblasts through increasing the expression of SIRT3.
