BACKGROUND:Along with the increasing improvement of bladder tissue engineering research, the vascularization of tissue-engineered bladder after implantation becomes an issue of concern. OBJECTIVE: Combined with relevant literature in recent years, to review the choice, design and application of scaffold materials for bladder tissue engineering as wel as vascularized strategies folowing implantation. METHODS:The first author retrieved PubMed database and CNKI databases for articles relevant to biological scaffold materials in bladder tissue engineering and vascularization of tissue-engineered bladder published between January 2000 to September 2014 using the keywords of “tissue engineering; bladder; biomaterials/scaffolds; vascularization” in English and Chinese, respectively. RESULTS AND CONCLUSION: Recently, the biological scaffolds for bladder tissue engineering include two main categories: natural biomaterials and synthetic polymers. The major target of bladder tissue engineering remains to prepare the best cel-seeded scaffolds, to determine the best source of stem cels, to explore the best differentiation way of stem cels, and to promote angiogenesis and nerve regeneration of implanted scaffolds. Thereinto, promoting vascularization of scaffold materials and building complex tissues is most chalenging. At present, it is stil difficult to precisely control the directional proliferation, migration and differentiation of the attached endometrial cels. Although the vascular network is necessary for the nutrient supply and metabolic waste removal of cels or tissues, strategies to promote angiogenesis or vasculogenesis are stil limited.

Objective To study the risk factors which lead to increase in the incidence rate of hypospadias. Methods A case-control design was used.The mothers of 210 cases and 420 controls were interviewed by telephone or face-to-face,and the questionnaires were answered.Thirty probable risk factors were investigated.Statistical analysis was performed using univariate and multivariate unconditional Logistic regression analyses for evaluation of the data. Results All boys with hypospadias in the case group were of Han nationality.Only 5 cases had positive family history.Odds ratio (OR) of the factors investigated were:pregnant age (OR,38.63),threatened abortion (OR,4.71),progestin (OR,3.64),estrogen (OR,5.1),pesticide (OR,2.39),organic solvents (OR,2.12),season of pregnancy (OR,1.86) and detergent (OR, 1.87).But OR of frequency of abortion,weeks of gestation and birth weight were less than 1.The results of other 17 investigated factors were negative. Conclusions Threatened abortion,nonfull-term fetus,low birth weight and some environmental endocrine-disturbing chemicals ( pesticide,detergent,organic solvents,progestin and estrogen) may be risk factors associated with hypospadias.These environmental endocrine-disturbing chemicals may increase the incidence rate of hypospadias.

Objective To evaluate the association between cytomegalovirus (HCMV) infection and atherosclerosis (AS) and explore the possible role of endothelin (ET) and serum tumor necrosis factor(TNF ?) in the pathogenesis of AS in diabetic patients and the relationship between HCMV infection and concentrations of ET and TNF ?. Methods Blood samples were collected from 21 patients with AS of type 2 DM, 47 patients with non AS of type 2 DM and 20 controls. Special antibodies to HCMV (IgM,IgG) were measured by enzyme linked immunosorbent assay (ELISA) . The concentrations of serum TNF ? and plasma ET were determined by RIA. Results (1) Type 2 diabetic patients, especially those with established AS, had a higher prevalence of active infection of HCMV. (2) The levels of plasma ET and serum TNF ? in type 2 diabetic patients were higher than those in normal people. In the pathogenesis of AS in diabetic patients, the ET played more important role than the TNF ?.(3) There was a significantly positive correlation between anti IgM to HCMV and the level of plasma ET in type 2 DM patients. It suggested that the injury of endothelium cell was related to the active infection of HCMV. Conclusion The study suggests that HCMV infection may be important in the pathogenesis of AS in type 2 diabetic patients and ET possibly plays an important role on the pathological course of AS.

ObjectiveTo observe the effect of long-term fluoride excess on rat thyroid morphology,thyroid peroxidase(TPO) activity and the expression of TPO protein,and to explore its possible mechanism of action.MethodsForty male SD rats were randomly divided into four groups by weight:control group,low-fluoride group,moderate-fluoride group and high-fluoride group(n =10),and they were fed with ordinary tap water containing fluorine 0.40,15.00,30.00,60.00 mg/L,respectively,and ate ordinary food prepared feed.After fed for 180 days,rats were anesthetized,and thyroid was taken.The morphology of thyroid was observed under light microscope.TPO activity was measured with improved guaiacol method.The expression of TPO protein was evaluated by Western blotting.ResultsThe thyroid histopathology results show:in control group,the thyroid follicular epithelial cells were columnar or cuboidal,with the follicular cavity filled with pink gum; in low-fluoride group,the thyroid follicular epithelial cell presented active hyperplasia; in moderate-fluoride group,the size of follicular increased,and follicular cavity was filled with dark,sticky colloid follicular; follicular increases,follicular cavity filled with dark,sticky colloid follicular; in high-fluoride group,the follicular epithelial cells showed apparent flat shape and excessive concentration of follicular colloid,a small amount of follicular lumen even showed the phenomenon of fusion,forming a giant follicular or cystic cavity.Among the four groups of control group,low-fluoride group,moderate-fluoride group and high-fluoride group,with increased fluoride,TPO activity [ ( 1.572 ± 0.046), ( 1.414 ± 0.086), (1.322 ± 0.049), (0.960 ± 0.083)U/L] decreased,and the differences were statistically significant between the two groups(all P ＜ 0.05).With increased fluoride,the expression of TPO protein (0.335 ± 0.011,0.156 ± 0.027,0.084 ± 0.020,0.045 ± 0.002) decreased,and the differences were statistically significant between the two groups(all P ＜ 0.05).Conclusioons Long-term intake of excessive fluoride can inhibit the thyroid TPO activity and the expressions of TPO as well as thyroid hormone synthesis,and leads to histological changes in rat thyroid.
