Objective To investigate the effect of rosiglitazone on the epithelial-mesenchymal transition process of renal tubular epithelial cell induced by transforming growth factor-β(TGF-β). Methods The human renal tubular epithelial cell line HK-2 was cultured in vitro and treated with TGF-β at the presence or absence of rosiglitazone, and the morphological changes of HK-2 cells were observed. Then PPARγ,SMAD family number 2/ 3,E-cadherin and Vimentin were detected by western blot, and the mRNA expression of PPARγ, E-cadherin, Vimentin, zinc finger transcription factor Snail and Slug were measured by realtime quantitative PCR. Finally,dual luciferase reporter assay was performed to detect the effect of TGF-β and rosiglitazone on the tran-scription activity of E-cadherin promoter. Results TGF-β could induce the EMT process of HK-2, including morphological changes such as longer pseudopod and broader cell space. TGF-β also activated the SMAD2/ 3 signaling pathway, with expression changes of E-cadherin and Vimentin. Rosiglitazone reversed the morphological changes of HK-2 cells induced by TGF-β, with shor-ter pseudopod and narrower cell space. Rosiglitazone also inhibited the mRNA and protein expressions of Vimentin, and restored the mRNA and protein expression of E-cadherin by up-regulating PPARγ. The activity of E-cadherin promoter was enhanced under the treatment of rosiglitazone. Conclusion Rosiglitazone can antagonize the EMT process of renal tubular epithelial cell induced by TGF-β, through the activation of PPARγ and stimulating transcription and protein expression of E-cadherin.

BACKGROUND:We have successfuly prepared digital coraline hydroxyapatite artificial bone scaffold in previous experiments, and it has been confirmed that it has the necessary physical and chemical properties of bone tissue engineering scaffolds. OBJECTIVE: To evaluate the sensitization of digital coraline hydroxyapatite artificial bone scaffold. METHODS:A total of 32 guinea pigs were randomly divided into saline group (negative control group, n=8), 5% formaldehyde group (positive control group,n=8), experimental A group (the mass ratio of 3:1,n=8), and experimental B group (the mass ratio of 4:1,n=8). Sensitization test at the maximal dosage was performed according toBiological Evaluation of Medical Devices-Part 10: Tests for Irritation and Delayed-Type Hypersensitivity, including intracutaneous induction, local induction, and provocation. Patch was removed after 24 and 48 hours, and the skin response was classified according to Magnusson and Kligman criteria. Patch was removed after 48 hours, and the skin was performed with biopsy, stained with hematoxylin-eosin, and observed under optical microscope. RESULTS AND CONCLUSION: Sensitization response was not tested in the negative control group, experimental A group and experimental B group at 24 and 48 hours after patch removal; however, moderate erythema was observed in the positive control group. Optical microscope demonstrated that spongiosis, edema, diffuse or perivascular mononuclear infiltration was not observed, and only a smal number of basicytes were seen in the experimental A and B groups. These findings indicate that the digital coral hydroxyapatite artificial bone scaffolds, with the mass ratio of 3:1 and 4:1, are biologicaly safe for sensitization.

Objective: To evaluate the influence of metabolic syndrome (MS) on coronary lesions in elder patients with hypertension.
Methods: A cohort of 210 hypertensive patients at the age of 60 years or elder who received coronary angiography in our hospital from 2012-06 to 2013-01 were studied. The patients were divided into 2 groups, MS group,n=85 and Non-MS group,n=125 patients without MS. The coronary lesion distribution, number and Gensini score were analyzed and compared between 2 groups.
Results: Compared with Non-MS group, MS group showed increased BMI, TG, HDL-C and fasting blood glucose, allP<0.001. There were no real differences for lesion distribution in left main, left anterior descending branch and the number of patients with normal coronary artery between 2 groups, allP>0.05. MS group had higher Gensini score, more lesions at left circumlfex and right coronary artery, more patients with coronary lesions and more patients with 3-branch disease,P<0.05. Logistic regression analysis indicated that MS is the independent risk factor for coronary lesions and the risk is higher than any single components of MS.
Conclusion: MS is related to the severity of coronary lesions in elder patients with hypertension.

After the structural reform in the food and drug supervision system, the knowledge structure and the professional re-quirements of the supervisors is unmatched, which hinder the fulfillment of regulatory responsibilities and the performance of adminis-trative efficacy. Effective ways for team building are actively explored throughout the country. The paper introduced the adult corre-spondence education of the supervisors in Zhejiang Ningbo food and drug supervision system to provide a good example for training work throughout the country and some useful suggestions for the quality improvement of the supervision team.

Food and drug supervision is a specialized job. However, the present supervisors coming from various departments have differences in supervision concepts, professional background, knowledge structure and work experience, which shows large gap with the requirements of supervision work. Therefore, it is urgent to strengthen the classified training for the improvement of quality construction and specialization. The article provided the curriculum system, teaching explanation and ideas about the classified training for all supervisors in the whole system, which may be beneficial to the training of food and drug supervisors.
