As a member of nuclear receptor superfamily, farnesoid X receptor (FXR) has been shown to regulate numerous metabolic pathways, which include playing an important role in bile acid metabolism, maintaining lipid and glucose homeostasis when FXR is activated. With the prevalence of the glucose and lipids disorder, FXR attracts increasing attention. It may be a potential target for the treatment of type 2 diabetes mellitus and lipid disorders.

Objective To ascertain the gross α/β levels in drinking water in Inner Mongolia and to estimate the annual effective dose to the local residents from radionuclides in drinking water.Methods A total of 768 water samples were collected from 101 counties distributed over 12 cities of Inner Mongolia.Low background α/β measuring instrument was used to measure the radioactivity level;On this basis,use EPA Federal Guidance Report 11 universal method to estimate the annual effective dose to the local residents via intake of radionuclides from drinking water.Results The gross α radioactivity range was 0.016-1.003 Bq/L for tap water,O.016-0.975 Bq/L for factory water,0.017-1.544 Bq/L for river water,0.120-0.672 Bq/L for lake water,0.016-0.492 Bq/L for reservoir water,0.016-1.139 Bq/L for well water,0.032-3.156 Bq/L for spring water,respectively.The gross β radioactivity range was 0.030-0.828 Bq/L for tap water,0.031-0.571 Bq/L for factory water,0.066-0.873 Bq/L for river water,0.169-2.268 Bq/L for lake water,0.046-0.519 Bq/L for reservoir water,0.071-0.526 Bq/L for well water,0.087-1.063 Bq/L for spring water,respectively.Conclusions In Inner Mongolia,the gross α/β mean value in tap water is less than the World Health Organization-recommended value and the average annual effective dose from tap water is also less than the WHO-recommended value O.1 mSv/a.The gross α/β radioactivity from the other water samples is also within the range of the nationwide average.

Objective To explore the effect of different doses of irbesartan on osteopontin expression and fibrosis in diabetic rat kidney. Methods Sixty-three g-week old male Wistar rat were randomly divided into control group (Ctrl group,n=7),diabetes group (DM group,n=14),30 mg·kg-1d-1 hydralazine administrated group (DM+Hyd group,n=12),25 mg·kg-1·d-1 irbesartan administrated group (DM+Irb25 group,n=10),50 mg·kg-1 ·d-1 irbesartan administrated group(DM+Irb50 group,n=9) and 200 mg·kg-1·d-1 irbesartan administrated group (DM+Irb200 group,n=11).Four weeks after modeling,rats were administered with the corresponding dose of irbesartan.After 12 weeks,urinary albumin excretion rate (UAER),endogenous creatinine clearance rate (Ccr) were measured; morphology and collagen deposition in rat kidney were observed by PAS and Masson staining respectively; Ang Ⅱ content in kidney was measured by ELISA; renal tissue TGF-β1 and OPN mRNA expression were detected by real-time PCR. Results UAER and Ccr in the intervention groups of irbesartan were significantly decreased compared with DM group (P<0.05).UAER and Ccr in DM+Irb200 group were significantly lower than those in DM+Irb25 group and DM + Irb50 group (P<0.05).Glomerular hypertrophy,mesangial matrix expansion,tubular lesions and deposition of collagen fiber were siginficant in diabetic rats compared with Ctrl,and prevented after administration with different doses of irbesartan.Ang Ⅱ protein level and TGF-β1,OPN mRNA expression in renal tissue of diabetic rats were significantly higher than those in Ctrl group.Ang Ⅱ,TGF-β1,and OPN mRNA expression was significantly reduced after administration with different doses of irbesartan,and with the increase of irbesartan,the above indicators were decreased P<0.05).Renal local Ang Ⅱ level was positively correlated with OPN mRNA expression (r=0.74,P<0.01). Conclusion Irbesartan reduces renal TGF-β1,OPN mRNA expression by decreasing kidney local Ang Ⅱ in dose-dependent manner,and eventually reduces tubulointerstitial fibrosis,which plays a role in kidney protection.

Objective To explore if Ulinastai reverses hepatofibrosis in rats.Method Rat hepatofibrosis models were induced by TAA subcutaneously injection.18 rats with hepatofibrosis were divided into 2 groups,Ulinastai treatment group (9 rats),normal saline control group (9 rats).AST,ALT,HA,SOD,MDA,LN level were measured and compared between the 2 groups and that of healthy rats (3 rats).Rats liver morphology was observed using HE,Masson stain and type-B ultrasonic.TGF-β1、caspase-3 were detected by immunohistochemistry.Result After 3 weeks Ulinastai treatment,elastic index and SSS score in Ulinastai group decreased significantly compared to pretreatment (t =2.472,P <0.05).ALT,AST,SOD,MDA,HA and LN level significantly improved (F =3.862,5.774,3.442,4.157,4.173,3.674,P < 0.05).Compared with NS treatment group HE and Masson staining showed fewer inflammatory cells infiltration in central vein,ballooning degeneration of liver cells,collagen proliferated,hepatic lobules degradation and pseudolobule arise after 3 weeks intervenion.Also in Ulinastai group,TGF-β1、caspase-3 positive cells were much less than that in NS treatment group.Conclusions Ulinastai can reverse rat hepatic fibrosis and alleviate fibrosis degree and collagen fiber deposit.

AIM: To investigate the effect of aminoguanidine (AG) on plasma and renal levels of angiogenesis Ⅱ (AngⅡ), and to identify the relationship of AGEs with AngⅡ in STZ-induced diabetic rats. METHODS: Wistar rats were randomly assigned to three groups. Diabetes was induced, rats were then received AG in treatment group. At the end of 12th week, urine albumin excretion rate (UAER) and calculate creatinine clearance (Ccr) were detected. Periodic acid-Schiff reagent was used to evaluate renal pathology. Plasma and renal AngⅡ were analyzed by radioimmunoassay and immunohistochemistry, respectively. RESULTS: AG treatment significantly prevented the increase in UAER (P<0.01), renal pathology (P<0.01), and level of renal AngⅡ (P<0.01). However, plasma concentration of AngⅡ was higher than that in diabetic rats without AG treatment (P<0.01). CONCLUSION: AG down-regulates renal Ang Ⅱ level, probably by reducing the formation of AGEs, which may be one of the renoprotective factors in diabetic nephropathy. More proofs are needed to identify the result that plasma AngⅡ concentration increases in DMA group.

BACKGROUND: Bushen Huogu decoction can effectively prevent and treat osteoporosis, but the concrete mechanism of pharmacology is still not clear. 25-hydroxy vitamin D3 and 1, 25-dihydroxyvitamin D3 are important coupling factors, which can regulate bone resorption and formation.OBJECTIVE: To investigate the curative effects of Bushen Huogu decoction on the bone mineral density, bone biomechanics, and level of 25-hydroxy vitamin D3 and 1, 25-dihydroxyvitamin D3 in blood serum, liver and kidney in the ovariectomized osteoporotic rats.METHODS: Totally 108 healthy female Sprague-Dawley rats were randomly divided into model group, sham-operated group, andtreatment group. All rats had been ovariectomized to induce estrogen absence and further establish osteoporotic models, except those in sham-operated group. Treatment group of rats were intragastrically administrated with 2 mL Bushen Huogu decoction,twice a day.RESULTS AND CONCLUSION: Compared with model group, the bone mineral density in the rat femur was significantly increased in the treatment group (P < 0.05), the index of maximal stress and maximal loading of the femoral head were also increased (P <0.05). The concentration of 25-hydroxy vitamin D3 and 1, 25-dihydroxyvitamin D3 in blood serum, liver and kidney were significant higher in the treatment group than those in the model group, and the levels were similar with those in sham-operated group (P >0.05). In the early period of estrogenic hormone absence, the Chinese kidney-tonifying drugs could activate bone metabolism, raise bone mineral density and reinforce quality of bone through up-regulating expression of 25-hydroxy vitamin D3 and 1,25-dihydroxyvitamin D3.
