Objective: To evaluate the the effect of two blood purification in patients with chronic renal failure uremia. Methods: One hundred cases of patients from April 2012 to February 2014 in our hospital were chosen as the experimental object, and were divided into experimental group and control group, control group were treated with hemodiafiltration, and the experimental group were treated with high-flux hemodialysis,the serum medium and small molecule toxins and cognitive function improvement were compared. Results:The serum medium and small molecule toxins and cognitive function of two group were greatly improved, there were significant differences(t=4.113, t=0.430, t=1.038, t=0.346; P<0.05).The experimental group after treatment, serum phosphorus, parathyroid hormone was lower than the control group, the difference was statistically significant (t=-4.189, t=4.113;P<0.05). The experimental group PL and Amp were better than the patients in the control group, the difference was statistically significant (t=15.023, t=3.428; P<0.05). Conclusion: Two blood purification has good effect on treating patients with chronic renal failure uremia, but the improving effect of high flux hemodialysis scavenging effect on cysC, parathyroid hormone and serum phosphorus and cognitive function are better than that of hemodiafiltration.

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.

ObjectiveTo study the effects of Epimedii Folium polysaccharides on mice with exercise-induced fatigue and explore its possible mechanism of action. MethodICR male mice screened by swimming training were randomly divided into a control group， model group， vitamin C group， and low， medium， and high dose groups of Epimedii Folium polysaccharides， with eight mice in each group. The exercise-induced fatigue model was established by weight-bearing swimming training in each group except for the control group. After two weeks of weight-bearing swimming， the Epimedii Folium polysaccharide groups were given 100， 200， 400 mg∙kg^-1 of Epimedii Folium polysaccharides by gavage， and the vitamin C group was given 200 mg∙kg^-1 of vitamin C by gavage. The control group and the model group were given equal amounts of saline for 14 d. At the end of the experimental period， the body mass of the mice in each group and the time of last swimming due to exhaustion were recorded. Serum urea nitrogen （BUN）， lactic acid （LA）， lactate dehydrogenase （LDH）， malondialdehyde （MDA）， superoxide dismutase （SOD）， glutathione peroxidation （GSH-Px）， myoglycogen （MG） in skeletal muscle， hepatic glycogen （HG） in the liver were detected by kits. Hematoxylin-eosin （HE） staining was used to observe the pathological changes in muscle tissue. Western blot was used to detect the protein expression of p38 mitogen-activated protein kinase （p38 MAPK）， phosphorylation （p）-p38 MAPK， extracellular signal-regulated kinase1/2 （ERK1/2）， nuclear factor-κB （NF-κB）， p-NF-κB， interleukin-1β （IL-1β）， and interleukin-6 （IL-6） in muscle tissue. The immunofluorescence （IF） method was used to detect the expression of tumor necrosis factor-α （TNF-α） in skeletal muscle tissue of mice in each group. ResultCompared with the control group， the body mass of mice in the model group decreased， and the time of last swimming due to exhaustion decreased （P<0.01）. In addition， there were significantly higher serum levels of the fatigue metabolites LA， LDH， BUN， and lipid peroxidation product MDA （P<0.01） and decreased levels of MG， HG， SOD， and GSH-Px （P<0.01）. The protein expressions of p-p38 MAPK， ERK1/2， p-NF-κB， IL-1β， IL-6， and TNF-α in skeletal muscle tissue were significantly higher than those of the control group （P<0.01）. Compared with the model group， the body mass and time of last swimming due to exhaustion of the mice in the low， medium， and high dose groups of Epimedii Folium polysaccharides and the vitamin C group were increased （P<0.05， P<0.01）， and the contents of LA， LDH， BUN， and MDA were significantly decreased （P<0.05， P<0.01）. The levels of MG， HG， SOD， and GSH-Px increased （P<0.05， P<0.01）， and the protein expression levels of p-p38 MAPK， ERK， p-NF-κB， IL-1β， IL-6， and TNF-α in skeletal muscle tissue decreased （P<0.05， P<0.01）. ConclusionEpimedii Folium polysaccharides can play a role in alleviating exercise-induced fatigue by inhibiting the p38 MARK/NF-κB signaling pathway， thereby reducing the accumulation of metabolites， improving the activity of antioxidant enzymes， increasing the glycogen content of the body， and reducing inflammation in skeletal muscle.

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.
