Tissue engineering provides urologists a new way to fix or reconstruct the impaired organs.Reconstitution of corporal bodies of penis with engineered tissue substitutes has been applied in animal models.In hypospadias reconstruction,the use of engineered tissue substitutes has been applied clinically.The clinical application of bladder tissue substitutes has been ongoing phase II clinical trial.Great progress has been made in renal replacement therapy with clinical application of human progenitor cells in hemofiltration units,and the engineered intracorporeal renal replacement unit will come true by additional studies.The current status of tissue engineering in clinical practice of urology is reviewed in this paper.

Objective To observe the effect of treating acute left heart failure with Shenmai injection and auxiliary conventional western medicine. Methods 132 patients were randomly divided into a control group and a treatment group, with 66 cases in each group. The control group was treated with lanatoside C, captopril, diuretics, and aminophylline. While the treatment group was additionally treated with Shenmai injection on the basis of the control group. Left ventricular ejection fraction(LVEF), left smothering end-diastolic diameter(LVEDD)value, the index of b-type natriuretic peptide(BNP), and 24 h dynamic electrocardiogram(ecg)were observed in both groups after 1 month’s treatment. Results LVEF and BNP were improved in both groups after the treatment[LVEF and BNP were(40.42 ± 4.32)%, (306.57 ± 201.21)pg/ml in the treatment group and(37.92±3.32)%, (451.51±294.23)pg/ml in the control group before the treatment;(35.28±4.15)%, (540.17±382.23)pg/ml in the treatment group and(35.13±2.35)%, (572.35± 422.21)pg/ml in the control group after the treatment], and the curative effect in the treatment group was better than the control group(P<0.05). LVEDD and 24 h average heart rate were also improved in both groups after the treatment [LVEDD and 24 h average heart rate were(59.81±59.81)mm, (79.62±6.38)times/min in the treatment group and(60.91±7.31)mm, (82.61±6.32)times/min in the control group before the treatment;(60.87 ± 7.75)mm, (85.03 ± 7.75)times/min in the treatment group and(61.81 ± 7.35)mm,(86.23 ± 8.35)times/min in the control group after the treatment], but there was no statistical differenc(P>0.05). Conclusion Shenmai injection has good effects in the treatment of acute left heart failure.

Objective The aim of this study was to observe the growth difference and expression of cytochrome C of skin hair follicles in neonatal mice .Methods The morphology of different skin hair follicles of neonatal mice ( postnatal day 1-9)were observed by HE staining histology and cytochrome C was detected by immunohistochemistry .Results The skin hair follicles in different parts of neonatal mice showed differences not only in morphology but also in developmental pe -riods.Hair follicle growth in the back and tail skin had a nonlinear and growing period .After the nonlinear and growing pe-riod they began to grow rapidly .The tail development was slightly slower than that on the back .The hair follicles of vibris-sae were very special , and started to develop without a stable period .Conclusions The results of morphological observa-tion and cytochrome C immunohistochemistry demonstrate that differences exist in the hair follicle morphology and develop -mental times in the skin of different parts of the body in neonatal mice .

Objective To assess prevalence and risk factors of illness within the past 2 weeks among rural residents in Menglian,under the background of essential public health service implemented generally. Methods In February 2012, the questionnaire method was employed to investigate the two-week morbidity in 2011 rural residents sampled by multistage stratified random sampling from Menglian population. Results The prevalence, that of illness within two-week among 2011 rural residents in Menglian, was 97.5‰ (95%CI 84.5‰-110.5‰) . It was lower than that of the rural region IV in China (149.6‰, <0.05) .Its age trend was the same as that of the rural region IV in China,the prevalence in 0-14 years old children,however,was higher than the counterpart in the rural region IV in China. The diseases, which two-week morbidity ranked the top five, were acute upper respiratory infection, acute gastroenteritis, hyperostosis, acute tracheobronchitis and rheumatoid arthritis. The results of multilevel logistic regression model fitted by group-level explanatory variable mountainous area, individual-level random slopes variable gender and other individual background variables indicated that there were across-level interactions between mountainous area and gender ( <0.05), the family income lower than RMB 15000 (odds ration 3.2378, 95%CI 1.9014-5.5130) and age (odds ration 1.0163, 95%CI 1.0002-1.0327) had a positive effect to two-week morbidity, and contrasting to unmarried, married had a negative effect to two-week morbidity (odds ratio 0.4727, 95%CI 0.2534-0.8819) . Conclusions Comparing with that of the rural region IV in China before implementing essential public health service, the two-week morbidity in Menglian was lower. For further elevating the health level of population, the strategies, such as intensifying material and child hygiene in the mountain area, improving sanitary conditions of low income family, and updating health consciousness in single population,would be implemented.

Objective:To explore the resource of rice bran by comparing antioxidative activities and growth promotion of Bacillus bifidus between supernatant of formented rice bran(RBF) by Bacillus natto and water extract of rice bran(RBW) . Method:The reducing capacity the?OH and ??O 2 scavenging capacity and the inhibitory effect to oxidize lard were determined in vitro. The growth promotion for Bacillus bifidus by photodensity with simulated condition was investigated in vivo. Results:RBF and RBW had antioxidant activity in vitro. The IC50 of scavenging?OH and ??O 250 of RBF was 3.55 mg/ml and 23.5 mg/ml,0.3 and 10 folds higher than that of RBW respectively. In inhibiting oxidation of lard,RBF had a little higher antioxidative activities than RBW,near VE. RBF and RBW could promot growth of Bacillus bifidus by 65.2% and 17.8% respectively. By enzymatic digestion,the promotive rate of RBF was still 51.6%. Conclusion:RBF had higher antioxidant activity and growth promotion to Bacillus bifidus.

Cartilage antuumor component (CATC) was isolated from a 1 mol/L guanidine hydrochloride extract of bovine cartilage by acetone fractioned precipitation and superfiltration. Using human skin fibroblasts as a normal control, it was demonstrated that CATC inhibited the DNA synthesis of Hela, QGY7703 tumor cell lines and bovine artery endothelial cells, but accelerated the normal cells, when the concentration was below 1250 ?g/ml. At the concentration of 5 000 ?g/ml, CATC inhibited the two cell lines. With human tumor stem cell assay, CATC inhibited the stem cell growth of Hela and QGY7703 cell lines. These suggest that CATC has the effects of inhibiting angiogenesis and tumor cells.

Objective To observe the effects of butylphthalide on the expression of autophagy-related protein and mRNA in l-meth-yl-4-phenyl-pyridiniumion (MPP+)-induced SH-SY5Y cells, and to explore the protective effect and possible mechanism of butylphthalide to the cell model of Parkinson's disease. Methods The SH-SY5Y cells were divided into control group (A), MPP+group (B), rapamycin pre-treated+MPP+group (C) and Butylphthalide pretreated+MPP+group (D). The relative viability of SH-SY5Y cells induced by MPP+was measured with MTT assay, the morphology of SH-SY5Y cells was observed. The expression of microtubule associated protein 1 light chain 3 (LC3)-II/I and Beclin 1 protein was detected by Western blotting. And the expression of LC3-II/I and Beclin 1 mRNA were assayed by re-al-time quantitative reverse transcription-PCR (RT-PCR). Results The viability rates of cells were significantly lower in group B than in group A (t=20.270, P<0.001), and were significantly higher in groups C and D than in group B (t>8.770, P<0.001), however, there was no significantly difference between groups C and D (t=2.270, P=0.064). The expression of LC3-II/I and Beclin 1 was higher in group B than in group A (t>6.647, P<0.01), and was higher in groups C and D than in group B (t>3.630, P<0.01), however, there was no significantly differ-ence between groups C and D (t<2.238, P≥0.05). Conclusion Butylphthalide could prevent the injury of SH-SY5Y cells induced by MPP+, which may affect Parkinson's disease by inducing autophagy.
