To study the protective effect of astragalus saponin extracts (AS) on kidneys of diabetic rats. Totally 32 diabetic rats induced by streptozotocin (STZ) were divided into AS high and low dose groups, the positive control group and the model group (DM group) and orally administered with 50 mg x- kg(-1) x d(-1) AS 200, 25 mg x kg(-1) x d(-1) valsartan, 10 mL x kg(-1) x d(1) physiological saline, respectively. Another 8 healthy rats were collected in the normal control group (NC group, physiological saline 10 mL x kg(-1). d(-1)). All rats were treated for consecutively 6 weeks. After the administration, the body weight was measured every week, the concentration of blood glucose was monitored on week 2, 4 and 6. The total urine and total urinary protein (U-TP) in 24 h were measured by the metabolic cage method on week 6; At the end of week 6, blood samples were collected from hearts to detect blood urea nitrogen (BUN), serum creatinine (Scr), uric acid (UA) , total cholesterol (CH) triglyceride (TG) by biochemical methods. Kidneys were collect to calculate the kidney hypertrophy index and observe the pathological sections. The laboratory results show that in the DM group, the blood glucose, metabolic cost in 24 h, kidney hypertrophy index, U-TP, BUN, Scr, UA, TG were significantly higher than that in the NC group (P < 0.01, P < 0.05) , with significant pathological changes; After the intervention with AS, the metabolic value in 24 h, kidney hypertrophy index, U-TP, BUN, Scr, UA, TG were significantly lower in the high dose group (P < 0.01, P < 0.05), and the kidney hypertrophy index, BUN, Scr, UA, TG in the low dose group were also significantly lower (P < 0.05), with slight reduction in renal pathological changes in both groups. In conclusion, Astragalus saponin extracts have a certain protective effect on kidneys of diabetic rats.

Microbial contamination, growth and reproduction have a great influence on the quality of traditional Chinese medicine (TCM) and its preparation. TCM may be polluted by microbial in the production process due to ambient air, facilities and appliances and operating personnel, which affects the quality and efficacy of the final product. The GMP certification inspection standard of TCM manufacturing enterprises clearly established: "Sterilization methods of Chinese herbal medicine, intermediate products, finished products should follow the principle whether or not to change its quality", "TCM powder that used as medicine directly should follow the principle whether to do microbiological examinations". So it's particularly important for product quality, corporate energy consumption and its efficiency to choose the scientific and effective sterilization techniques and methods. Ozone is a kind of safe, environmentally friendly, efficient and no residue emerging sterilization technology. It has been widely applied in various fields of medical and health care and production and living. This paper mainly analyzed the ozone sterilization technology of TCM, aiming to explore the principle of ozone sterilization, the advantages, application status and existing problems and so on. The management regulations and implementation rules of ozone sterilization were summarized to make sterilization of Chinese medicine in the production, management, quality control and other aspects standardized, reasonable and scientific, and to provide the theoretical reference of the ozone sterilization technology for TCM and its preparation.

The aryl hydrocarbon receptor (AhR) is a ligand-activated transcription factor that regulates gene expression in a range of cells, including immune and epithelial cells. AhR signaling plays important roles in the immune system in both health and disease states. Tapinarof is a first-in-class small-molecule topical therapeutic AhR modulating agent launched for the treatment of psoriasis. To improve the activity and chemical stability of Tapinarof, a series of 2-phenylchromen-4-one derivatives were designed, synthesized and evaluated as novel AhR agonists. Compounds 5a, 5c, 5e and 5f potently activated AhR with an EC₅₀ value of 7, 9, 6 and 6 nmol·L^-1, respectively, which are 10-14 fold more potent than Tapinarof. Compounds 5a and 5e exhibit comparable inhibitory effects on IFN-γ production as Tapinarof. Furthermore, compounds 5a-5f exhibited favorable photochemical stability compared to Tapinarof. The compounds may eventually serve as lead compounds for the development of new AhR agonists.

Objective To investigate the effect of high power microwave(HPM) irradiation on neuropeptide Y (NPY) and neural nitric oxide synthase (nNOS) expression in the cerebral cortex and hippoeampus of Wistar rats. Methods A total of 110 Wistar rats were used for this study.Three groups of 30 Wistar rats were exposed to HPM irradiation at intensities of 3,10,30 and 100 mW/cm~2,respectively.Twenty rats served as controls and were ex- posed to sham HPM irradiation.At 6 h,and at 1,3,7,14 and 28 d after irradiation,five rats from each group were sacrificed,and their cerebral cortices and hippocampi were harvested.HE staining was used to highlight any change in the structure of the cerebral cortex or hippocampus.Immunohistochemistry techniques and image analysis were used to study the changes in NPY and nNOS expression.Results 10 to 100 mW/cm~2 HPM irradiation caused pyc- nosis and deep staining of some neurons in the cerebral cortex and hippocampus.The increase in nNOS expression and decrease in NPY expression observed were significant at 3 days after irradiation.Conclusion HPM irradiation can induce injury in neurons of the cerebral cortex and hippoeampus,and abnormal NPY and nNOS expression.
