Recently, many Chinese doctors have treated metabolic syndrome from pathogenic phlegm, dampness, stasis and heat, which not only meets the theory of TCM, but also has achieved good clinical effects, besides the method has been confirmed by animal experiments..

Objective To explore the the influence ofFurong-Tongmai capsules on myocardial expression of LN and CollagenⅢ in diabetes mellitus (DM) rats.Methods A total of 60 rats were randomly divided into the control group, the model group, the low-, middle- high-dosageFurong-Tongmai capsules group (n=10). The low-, middle-high-dosageFurong-Tongmai group was given 1.4, 0.7, 2.8 g/(kg body weight) Furong-Tongmai capsules. The other two groups were given the same dose of purified water. After 8 weeks treatment, the myocardial was taken to make pathology slice with SP immunohistochemistry staining. The expression of LN and CollagenⅢ were detected.Results Compared with model group, the expression of LN (0.67% ± 0.04%,0.65% ± 0.09%vs. 1.08% ± 0.13%) and CollagenⅢ (0.67% ± 0.15%, 0.69% ± 0.13%vs. 1.17% ± 0.12%) in the middle-high-dosageFurong-Tongmai groups significantly decreased (P<0.05). However, there were no statistical differences between the low-, middle- high-dosageFurong-Tongmai groups and the model group (P>0.05).Conclusions TheFurong-Tongmai capsules could inhibit the expression of LN and CollagenⅢ in DM rats.

Objective To investigate the effects of Furong-Tongmai capsules on the expressions of interleukin-1 (IL-1) and tumor necrosis factor-α (TNF-α) in the sciatic nerve in diabetic rats.Methods A total of 50 rats were randomly divided into the normal control group,model group,and low-,medium-,and high-dose of Furong-Tongmai groups,10 rats in each group.Diabetes mellitus in rats were induced by intraperitoneal streptozotocin injection (60 mg/kg).The rats in the low-,medium-,and high-dose of Furong-Tongmai groups were intragastric administrated with Furong-Tongmai suspension 0.7,1.4 and 2.8 g/kg daily for 8 weeks,respectively.The rots in the normal control group and model group were intragastric administrated with equal-volume normal saline daily for 8 weeks.The expression levels of IL-1 and TNF-α in the sciatic nerve were detected with immunohistochemistry staining.Results The expression levels of IL-1 (1.43％ ± 0.17％ vs.0.21％ ± 0.09％;P＜0.05) and TNF-α (1.98％ ± 0.12％ vs.0.35％ ± 0.03％;P＜0.05) in the model group were significantly increased than those in the normal control group.The expression levels of IL-1 (0.54％ ± 0.14％,0.51％ ± 0.13％ vs.1.43％ ± 0.17％;all P＜0.05) and TNF-α (0.57％ ± 0.17％,0.49％ ± 0.15％ vs.1.98％ ± 0.12％;all P＜0.05) in the medium-,and high-dose of Furong-Tongmai groups were significantly decreased than those in the model group and low-dose of Furong-Tongmai group (1.08％ ± 0.18％ in IL-1,1.11％ ± 0.09％ in TNF-α;all P＜0.05).Conclusion Furong-Tongmai capsules can reduce the expressions of IL-1 and TNF-α in sciatic nerve in diabetic rats.

BACKGROUND:The establishment of a safe, reliable and easily repeatable mouse model of nonalcoholic fatty liver disease is the prerequisite for the study of the diagnosis and treatment of the disease.
OBJECTIVE:To establish a C57BL/6 mouse model of nonalcoholic fatty liver disease and observe changes of biochemical indicators, which can provide a theoretical basis for its pathogenesis and drug treatment.
METHODS:Sixty healthy male C57BL/6 mice were randomly divided into a control group of 30 cases (normal diet), and a model group of 30 cases (high fat diet). Models of nonalcoholic fatty liver were established. At 8 weeks, body mass, liver index, and homogenate superoxide dismutase activity in the liver were detected. Changes in serum alanine aminotransferase, aspartate aminotransferase, triglyceride glycerol, cholesterol, high-density lipoprotein cholesterol and low-density lipoprotein cholesterol were observed. Pathological examination was performed.
RESULTS AND CONCLUSION:(1) Pathological sections showed that large droplets and smal lipid droplets in the mouse liver and spread the whole liver. Swel ing of the liver cel s, visible cytoplasmic vacuoles and obviously inflammatory changes in liver cel s were observed in the model group. (2) Body weight and liver index were significantly higher in the model group than in the control group (P<0.05). Superoxide dismutase activity was significantly reduced in the liver (P<0.05). (3) Triglycerides, cholesterol, and low-density lipoprotein cholesterol levels were significantly higher, but high-density lipoprotein cholesterol levels were significantly lower in the model group than in the control group (P<0.05). (4) Nonalcoholic fatty liver mouse model is ideal for high-fat diet-induced animal model. The method is simple, repetitive, and can provide a stable animal model for the study on the mechanism of nonalcoholic fatty liver disease and drug treatment.
