Objective To observe the effects of Dengzhanhua Capsule on kidney tissue inflammatory cytokines in chronic renal failure rats;To explore its possible mechanism for the efficacy in chronic renal failure. Methods Sixty SD rats were randomly divided into normal control group, model group, benazepril group and Dengzhanhua group, 15 rats in each group. Chronic renal failure rat model was established by Platt 5/6 nephrectomized. Benazepril (0.29 mg/100 g) was given to rats in the benazepril group by gastrogavage. Dengzhanhua Capsule (0.3 g/100 g) was given to rats in the Dengzhanhua group by gastrogavage. Normal saline was given to rats in the normal group and the model group by gastrogavage. The whole treatment period was twelve weeks. Expressions of TGF-β1 and PAI-1 were determined by semi-quantitative RT-PCR after treatment. Concentrations of kidney tissue inflammatory cytokines IL-6 and TNF-α were determined by ELISA. Results Expressions of TGF-β, PAI-1 and IL-6, TNF-αin benazepril group and Dengzhanhua group were significantly lower than those in model group (P<0.05). Compared with benazepril group, it was significantly lower in Dengzhanhua group (P<0.05). Conclusion Dengzhanhua Capsule can reduce kidney tissue inflammatory in chronic renal failure rats, and inhibit renal fibrosis.

As a Chinese saying goes， "good Chinese medicinal material makes good medicine"， the quality of Chinese herbal medicines is related to the development prospect of Chinese medicine industry in China. With the rapid development of new technologies such as traceability methods and monitoring instruments， it is imperative to integrate and innovate traditional Chinese herbal medicines with new-generation information technology in view of the quality problems existing in the current production and circulation of Chinese herbal medicines， and it is of great significance for the construction of traceability system to ensure the quality and safety of Chinese herbal medicines and to promote the industry of Chinese herbal medicines to move towards high-quality development. This paper reviews the development history of the traceability system of Chinese herbal medicines in China， takes the influencing factors of the quality of Chinese herbal medicines as the entry point， and proposes that the construction of the traceability system should satisfy the traceability requirements of the characteristics of Chinese herbal medicines and their traditional medication experience. By analyzing the influencing factors of the quality of Chinese herbal medicines， it is pointed out that focusing on the influencing factors to build a traceability system is of great significance for targeting the problematic links at a later stage and exploring the interrelationship between environmental factors and the quality of Chinese herbal medicines. Based on the previous explorations， the author summarizes the system framework， functional modules and practical applications of the traceability system of Chinese herbal medicines， and looks forward to the development of a traceability system with risk early warning function and expert decision-making function in its functional development. Finally， based on the factors affecting the quality of Chinese herbal medicines， the author puts forward several thoughts on construction of the traceability system， and makes an in-depth analysis and puts forward a solution for the current situation that a unified， standardized and universal traceability system has not yet been built， with a view to providing ideas and references for the construction of traceability system of Chinese herbal medicines.
