Hyperuricemia mice model was established with uricase inhibitor (potassium oxonate) and uric acids in serum were observed. Polydatin (5, 10, 20 mg · kg(-1)) and benzbromarone (16.7 mg · kg(-1)) were given ig for 7 d in mice. Kidney tissues were used to detect gene contents ofurate anion transporter 1 (URAT1), organic anion transporter 1 (OAT1) and organic anion transporter 3 (OAT3) by real-time-PCR. The results showed that polydatin and benzbromarone can significantly reduce uric acid in blood of hyperuricemia mice (P < 0.05), compared with the model group. URAT1, OAT1 and OAT3 contents of the kidney in hyperuricemia mice changed significantly (P < 0.05), compared with the blank group. Polydatin can significantly inhibit the changing trends in these genes induced by potassium oxonate in a dose-dependent manner, the difference was significant (P < 0.05), compared with the model group. Those indicated that polysatin could reduce the level of the serum uric acid through promoting uric acid excretion.

Objective To investigate the effect of UCP2 on cell proliferation, apoptosis, metastasis in cervical squamous carcinoma. Methods Plasmid?mediated downregulation of UCP2 was obtained in cervical cancer cell lines. MTT, flow cytometry and transwell chamber assay were conducted to detect the ability of proliferation, apoptosis and metastasis. Characteristics of UCP2 protein was analyzed by bioinformatics methods. Results (1)UCP2 was verified to be downregulated by qRT?PCR and Western blotting assay.(2)MTT, apoptosis assay and transwell chamber assay showed that the proliferation of SiHa cell was significantly inhibited, and the apoptosis rate was significantly increased, and metastasis was markedly deduced (P < 0.05). (3) Bioinformatic analysis showed that UCP2 was located in mitochondria with several phosphorylation sites, and UCP2 interacted with other proteins to produce biological effects. Conclusion UCP2 may play an important role in the occurrence and development of cervical cancer, and it is expected to be a new target for the early diagnosis and treatment of cervical cancer.

Objective:To evaluate the therapeutic effects of sinomenine on T-helper cell type 1-mediated experimental colitis in-duced by 2,4,6-trinitrobenzene sulfonic acid (TNBS) in mice. Methods:Balb/c mice were divided into five groups:ethanol control group, TNBS model group, and sinomenine treatment groups (50, 100 and 200 mg·kg-1 ) with 10 ones in each. Colitis was induced by colonic instillation of TNBS dissolved in 0. 1 ml of 50% ethanol. Seven days after the colonic instillation of TNBS, sinomenine was given by gastric gavage once daily for 21 days. The mice were sacrificed on the 28th day, the injury degree of colonic mucosa was ob-served, the colon myeloperoxidase ( MPO) activity was determined, and the levels of inflammatory cytokines ( TNF-α, IL-17 and IL-23) were determined by ELISA. Results:Compared with those in TNBS model group, the body mass, gross injury score and histologi-cal findings in sinomenine groups at medium dose and high dose were significantly improved (P<0. 05), the activity of MPO signifi-cantly decreased (P<0. 05), and the protein levels of TNF-α, IL-17 and IL-23 in colonic mucosa were lower than those in TNBS group (P<0. 05). Conclusion:Sinomenine has notable therapeutic effect on TNBS-induced chronic colitis in mice, and the mecha-nism is related to the inhibition of Th1 cytokines by sinomenine.

Objective To establish a method of isolating and purifying islets from Wistar rat, and to evaluate the biological characters of the isolated and purified islets. Methods The pancreases were surgically removed from adult Wistar rats, carefully minced with scissors as small as possible prior to incubation in 0.9 mg/ml collagenase (Sigma, type Ⅴ) for 10~17min at 37℃. The digested tissue was filtered through a 60 apertures/cm~2 metal sieve and washed with 10% fetal bovine sera (FBS) in Hank’s solution. Purification was performed using Dextran discontinuous density gradient centrifugation to separate the contents of the postcollagenase pellets. Islet samples were stained with DTZ staining for identification. The viability of the purified islet was determined by acridine orange/propidium iodide (AO/PI) double staining. The in vitro function was assayed by different densities of glucose incubating islets for 45min, respectively. Insulin secretion in the supernatant was assayed by radioimmunoassay. Islets were transplanted under the kidney capsule into recipient SD rats that had been rendered diabetic by injecting streptozotocin 50mg/kg, so as to evaluate the in vivo function of islets. Results The islets were recovered between the 11% and 22% Dextran layers, and between the 11% and 1640 layers. The average number of isolated islets was 2181?14 per rat pancreas. After a discontinuous Dextran density gradient purification, about 1826?24 islets were obtained from per rat pancreas, with an average purity over 95%. Islets showed good response to glucose and high efficiency to invert hyperglycemia 7-10d after transplantation. Conclusion These results showed that the digestion methods and purification procedure which we have developed could provide islets from rats for transplantation studies. The biological characters of islets harvested by our method were very well.

Microbiome is a novel research field related to human health,agriculture,bio-energy and the environment. Gut microbiome has received much attention from researchers recently. Studies have shown that gut flora is related to some diseases,such as digestive disease(inflammatory bowel disease),metabolic disease(type 2 diabetes), cardie-cerebral vascular disease(Parkinson disease). Traditional Chinese materia medica(TCMM) has long been used as a tonic and taken in a large amount. Gut flora has an effect on pharmacology and toxicology of TCMM after entering the gastroin?testinal tract. This article is intended to review recent researches on microbiome,common detection techniques and the relationship with hepatotoxicity induced by Polygonum multiflorum Thunb.,scutel?laria baicalensis that directly affects the intestinal tract,nephrotoxicity induced by Rhizoma Alismatis and pneumonia induced by Xiao-Chaihu-Tang.
