Echinococcosis is a severe zoonosis parasitic disease and mainly caused by the larvae of Echinococcus granulosus and E. multilocularis. Because of the limitation of operation level,such as recurrence and death,the drug treatment is still the most important method in our country. Meanwhile,the annual number of drug treatments is far greater than surgical treatments. Drugs play a significant role in the preoperative reduction of lesions,reducing pain,extending the life of patients .This article re-views the status of animals treatment and clinical treatment of echinococcosis treated by the benzimidazole drugs and their new formulations,provides the basis for exploring the development direction of anti-echinococcosis drug treatment research.

Objective To investigate the relationship between diabetes and bone metabolism and the potential epigenetic mechanisms. Methods BMSCs were cultured for 7 and 15 days in cell culture medium with different concentrations of glucose. The mRNA and protein expression of HDACs and osteogenesis-related genes were detected by RT-PCR and Western blot assay ,respectively. Moreover ,the combination of HDAC to the promoter region of Runx2 was tested by the chromatin immunoprecipitation (ChIP) assay. Results ThemRNA expression of osteogenesis-related genes ,incuding OCN(P < 0.05)and Col1(P < 0.05),in the bone marrow of diabetic mice was significantly reduced compared with the control mice. The mRNA and protein expression of ALP ,OCN ,Runx2 and OSX was gradually reduced with the increasing concentration of glucose ,while HDAC2 mRNA and protein expression was increased. The binding activity of HDAC2 to the upstream and downstream of Runx2 promoter region in 25mM glucose-treated BMSCs was higher than the control group(P < 0.05). Conclusoins Diabetes might repress osteogenesis of BMSCs via inhibiting the activity of Runx2 through upregu-lating the expression of HDAC2.

Purpose Dual-energy coronary artery CT angiography (CTA) is a very promising one-stop examine, but the radiation dose is too high to hinder the development of the technology. The aim of this article is to explore the feasibility of low tube current combined with sonogram-affirmed iterative reconstruction (SAFIRE) technology in dual energy coronary artery CTA scan. Materials and Methods One hundred and twenty patients were randomly divided into four groups according to the tube current of A ball:conventional group (180 mAs) and low-dose groups (150 mAs, 120 mAs, 90 mAs). The SAFIRE 3 reconstruction method was used in the low-dose groups. The differences of mean CT values, image noise, signal-to-noise ratio (SNR), contrast-to-noise ratio (CNR), image quality score and effective dose (ED) of the four groups were compared. Results The coronary artery segment display and the mean CT value of the four groups showed no statistic difference (P>0.05), while the image quality score, noise, SNR, and CNR showed statistic difference (P<0.05). The image quality score, SNR, and CNR was highest in the 150 mAs group, but noise was the lowest. There were no statistic difference of the image quality score, SNR, and CNR between the 180 mAs group and 90 mAs group (P>0.05). The ED was (5.50±1.47) mSv, (4.55±1.16) mSv, (3.41±0.77) mSv and (2.44±0.67) mSv, respectively for the four groups, and there was statistical difference (P<0.05). ED of 90 mAs group decreased 55.62% than that of 180 mAs group. Conclusion Coronary artery CTA using 90 mAs combined with SAFIRE can significantly reduce the radiation dose without losing image quality, thus it has a good prospect of clinical application.

Objective To investigate the expression of Erbin in renal interstitial fibrosis (RIF) and the effect of over-expression of Erbin on transforming growth factor β1 (TGF-(β1)-induced epithelial-mesenchymal transition (EMT) in NRK52E cells. Methods In vivo, the model of renal fibrosis was induced by 5/6 subtotal nephrectomy in rat. Scr and BUN was detected and Masson staining was used to evaluate the level of renal tissue fibrosis. The location and expression of Erbin in renal tissue were detected by immunohistochemistry and Western blotting. In vitro, after NRK52E cells were treated by TGF-β1 (10 μg/L) for 72 h, immunofluorescence and Western blotting were used to obverse the expression and distribution of E-cadherin and α-SMA. The expression of Erbin mRNA and protein were detected by RT-PCR and Western blotting respectively. NRK52E cells were transiently transfected with Prk5-myc-Erbin plasmid via lipofectamine 2000, then the expressions of Erbin, E-cadherin and α-SMA were detected by Western blotting. Results (l)Compared to sham group with Scr (33.96±7.28) μmol/L and BUN (8.11±2.55) mmol/L, rats in 5/6 nephrectomy model with Scr (140.52±61.11) μmol/L and BUN (34.23±7.66) mmol/L revealed renal dysfunction. Masson staining indicated kidney interstitial fibrosis, and the expression of Erbin was significantly increased in renal tissue(2.9 folds), especially in tubular epithelia. (2)In vitro, the expressions of Erbin and α-SMA were markedly increased (2.3 folds and 2.1 folds, P<0.05, respectively) and the expression of E-cadherin was dramatically decreased in NRK52E cells stimulated by TGF-β1, which were consistent with immunofluorescence results. TGF-β1-induced E-cadherin suppression and a-SMA induction could be efficiently blocked by over-expression of Erbin (all P <0.05). Conclusions Erbin is up-regulated in renal interstitial fibrosis, and over-expression of Erbin can partly inhibit renal EMT induced by TGF-β1, which indicates Erbin playing an protective role in renal fibrosis.
