OC-STAMP Overexpression Drives Lung Alveolar Epithelial Cell Type II Senescence in Silicosis.

Cellular senescence has been considered an important driver of many chronic lung diseases. However, the specific mechanism of cellular senescence in silicosis is still unknown. In the present study, silicotic rats and osteoclast stimulatory transmembrane protein () overexpression of MLE-12 cells were used to explore the mechanism of OC-STAMP in cellular senescence in alveolar epithelial cell type II (AEC2).

[Effect of N-acetyl-seryl-aspartyl-lysyl-proline on differentiation from pulmonary fibroblast to myofibroblast mediated by Rho-associated coiled-coil forming protein kinase pathway].

Objective: To investigate whether N-acetyl-seryl-aspartyl-lysyl-proline (Ac-SDKP) can inhibit the differentiation of pulmonary fibroblasts into myofibroblasts by regulating Rho-associated coiled-coil forming protein kinase (ROCK) pathway mediated by transforming growth factor-β1 (TGF-β1).

Methods: Primary culture of pulmonary fibroblasts was performed by trypsinization method. Four generations of pulmonary fibroblasts were divided into control group, TGF-β-induced differentiation group, Y-27632 treatment group, and Ac-SDKP treatment group.

[Regulating effect of N-acetyl-seryl-aspartyl-lysyl-proline on activation of c-jun N-terminal kinase pathway in rats with silicosis].

Objective: To investigate the regulatory effect of N-acetyl-seryl-aspartyl-lysyl-proline (AcSDKP) on the activation of c-jun N-terminal kinase (JNK) signal transduction pathway and its role in silicotic fibrosis.

Methods: A rat model of silicosis was developed by intratracheal instillation. Sixty rats were randomly divided into 4-week control group (n = 10), 8-week control group (n = 10), 4-week silicosis model group (n = 10), 8-week silicosis model group (n = 10), AcSDKP treatment group (n = 10), and AcSDKP prevention group (n = 10).

Isolated splenic tuberculosis: A case report.

We present a rare case of a 36 year old man who presented with recurrent fever but no other symptoms. Laboratory data provided no specific information for diagnosis. Abdominal ultrasonography revealed splenomegaly with multiple small hypoechoic lesions within the spleen.

[Effect of N-acetyl-seryl-aspartyl-lysyl-proline on regulation of expression of ras-raf-ERK1/2 signal transduction pathway in lung of rats with silicosis].

Objective: to investigate the effect of N-acetyl-seryl-aspartyl-lysyl-proline (AcSDKP) on the expressions of c-Raf, ERK1/2 and TGF-β1 in the lung of rats with silicosis, thus to investigate the regulating of AcSDKP on the Ras-Raf-ERK1/2 signal transduction pathway.

Methods: rats were instilled with silica through trachea as silicotic models and administered AcSDKP in the experiment. Rats were divided into 6 groups randomly, 10 rats in each group: Control 1 and 2 of silicotic model: each rat was intratracheally instilled with 1.

[Effect of paeonol on protecting endothelial cells of diabetic rats].

Objective: To study the effect of paeonol on protecting endothelial cells of diabetic rats.

Methods: Streptozocin was used on rats to make diabetic models. Different dosages of paeonol were fed on all the model rats.

[The summary of the clinic study of Zhi-Xin-Fang treating the heart failure resulting from cardiomyopathy].

Objective: To observe the therapeutic and prognostic effects and to evaluate the safety of Zhi-Xin-Fang on heart failure resulting from cardiomyopathy.

Methods: 62 patients with cardiomyopathy combined with heart failure were treated with standard western medical therapy as treatment group. The other 60 patients with the same diseases were administered with both Zhi-Xin-Fang and standard western medicines as control.

[Effect of cortex moutan on PGI2, TXA2, ET and NO in diabetic rats].

Objective: To study the effect of Paeonol on PGI2, TXA2, ET and NO in diabetic rats.

Methods: Streptozocin was used on rats to make diabetic animal models. Different dosage of Paeonol were used on diabetic animal models.
