Aim To study the oxygen free radical scavenging activities and antilipid peroxidation of nicotinic acid. Methods High lipid models of quail were induced by high fat diet. Five groups were divided, namely control group, high lipid group, NA group(150 mg?kg-1 and 75 mg?kg-1), and Vit E group (100 mg?kg-1). The contents of TC,TG,MDA and activities of SOD were examined for 3 times in the plasma and liver after administering NA for 9 weeks. Results The results showed the increase of TC,TG and MDA contents and decrease of SOD activities in high lipid groups by 3 weeks high fat diet. After administering NA for 3 weeks, NA reduced TC,TG and MDA contents and increased SOD activities, revealing the relationship to dose-dependence. Conclusion NA is most likely to possess the capabilities of anti-oxygen free radicals and anti-lipoperoxidation to hyperlipodemia quail.

OBJECTIVE:
To observe the expression of IL-9, IL-17 and Foxp3 in nasal polyps,so that to explore the role of Th9, Th17/Treg cells imbalance in pathogenesis of nasal polyposis.
METHOD:
Forty cases of nasal polyps and 20 cases of normal middle turbinate mucosa (controls) were involved in this study. The expression patterns of IL-9, IL-17 and Foxp3 were detected by immunohistochemistry.
RESULT:
The positive rates of IL-9 and IL-17 in nasal polyps tissues were respectively 75.0% and 80.0%, which were both significantly higher than those in the controls (positive rates were 35.0% and 50.0%, respectively), but the Foxp3 expression was downregulated in nasal polyps tissues (37.5%) compared to the controls (80.0%), P < 0.05 respectively.
CONCLUSION
The cytokines IL-9 and IL-17 are obviously involved in the occurrence and development of nasal polyposis, suggesting remarkable infiltration of Th9 and Th17/Treg imbalance exist in nasal polyps, both of which may play important roles in pathogenesis of nasal polyposis.

Radiation-induced skin injury refers to the acute and chronic skin damage caused when skin is exposed to radiation. Radiation-induced skin damage may be created by nuclear disaster, radiation accident, radiation therapy, occupational exposure and so on. Approximately 95% of patients receiving radiotherapy will eventually develop into radiation-induced dermatitis during or after the treatment. As a consequence, how to appropriately prevent and remedy radiation-induced skin injury is of great practical significance. According to traditional Chinese medicine, radiation-induced skin injury belongs to fire, heat and toxin, blocking Qi and blood, injuring the muscle surface, affecting the distribution of Qi, blood and body fluid in the body, and damaging the function of viscera. This paper summarizes the cognition and development of traditional Chinese medicine theory of radiation-induced skin injury, as well as the research progress of internal and external treatment of traditional Chinese medicine, so as to provide a basis for the research and treatment of radiation-induced skin injury with traditional Chinese medicine.

OBJECTIVETo observe the expression of Ginkgo biloba Tablet (GbT) on scavenger receptor A (SRA) of the aortic wall and changes of serum inflammatory factors in atherosclerotic rats, and to explore its new mechanism for fighting against atherosclerosis (AS).
METHODSTotally 45 male Wistar rats were randomly divided into the control group, the model group, the GbT group, 15 rats in each group. Levels of blood glucose, blood lipids, blood calcium, serum C-reactive protein (CRP), soluble intercellular adhesion molecule-1 (slCAM-1), and soluble vascular cell adhesion molecule-1 (sVCAM-1) were measured in all rats. The expression of SRA in the aortic wall of atherosclerotic rats was observed by immunohistochemical assay. The correlation between the expression of SRA and levels of in-flammatory factors was also observed.
RESULTSCompared with the control group, blood glucose and blood calcium obviously increased (P < 0.05); levels of TG, TC, and LDL-C were significantly elevated (P < 0.01); neointimal areas were significantly thickened, increased intima percentage was significantly enlarged, narrowed lumen index was significantly reduced; levels of CRP, sICAM-1, and sVCAM-1 were significantly elevated in the model group (all P < 0.01). Compared with the model group, blood glucose and blood calcium obviously decreased (P < 0.05); levels of TG, TC, and LDL-C significantly decreased (P < 0.01) in the GbT group. Aortic lumens were obviously narrower in the model group than in the GbT group (P < 0.05). SRA expressed at the aortic wall. The aforesaid 3 indices were significantly improved in the GbT group than in the model group (P < 0.01). Serum levels of CRP, sICAM-1, and sVCAM-1 were significantly decreased in the GbT group than in the model group (P < 0.01). Serum levels of CRP, sICAM-1, and sVCAM-1 were positively correlated with the percentage of SRA positive expression area (r = 0.701, 0.604, 0.581, all P < 0.01).
CONCLUSIONSSerum levels of inflammatory factors in atherosclerotic rats were elevated, and the expression of SRA in the aortic wall was enhanced. The expression of SRA was closely correlated with serum levels of inflammatory factors. GbT could decrease serum levels of inflammatory factors and inhibit the expression of SRA.
