Tissue engineering has evolved as a dynamic research field that encompasses multidisciplinary approaches involving cytology,material science,bioreactor engineering,and medicine.The overarching goal is to construct human tissue and organs in the laboratory for tissue regeneration or replacement.It offers a potential solution to the donor shortage in organ transplantation and to the difficulties in regenerative medicine.The basic components for tissue engineering include seed cell selection,bio-scaffold construction,and ex vivo tissue formation via a bioreactor. Over the past decade,tremendous progress has been made in bioengineering cartilage,trachea,urinary bladder,heart valve and endocrine tissues. However,there remain significant challenges in creating complex and human-sized tissues and organs for clinical use.In this article,we review the basic components and strategies for bioengineering organs. We attempt to provide an overview of current progress and challenges in developing organ-level tissue engineering and in the successful translation of bioengineered tissue and organ products into daily clinical practice.

Objective: To analyze the equity of benefit which residents with different income get from Urban Employee Medical Insurance ( UEMI) and New Rural Cooperative Medical System (NCMS). Methods: Data used in this study is based on the forth household health service survey in Shanxi province. The indirectly standardization method and concentration index were employed to analyze the horizontal inequity index of benefit rate and benefit degree. Results:The horizontal inequity index of benefit rate and benefit degree in UEMI are 0.0524 and 0.0025, and the horizontal inequity index of benefit rate and benefit degree in NCMS are 0.2312 and 0.3228. Conclusion: The urban residents get the equal benefit from UEM, and there were pro-rich horizontal inequities of benefit rate and benefit degree in NCMS.

Objective:To study the effects of vitamin C (VC) on the injury of alveolar macrophages exposed to Ni2O3 in vitro and the expression of inducible nitric oxide synthase (iNOS). Method:The alveolar macrophages were cultured with exposure to Ni2O3 in vitro. Meanwhile,VC with different concentrations (25,50 and 100 ?mol/L) were added to the medium, respectively. The cell activity,nitric oxide(NO),reactive oxygen species (ROS), malondialdehyde (MDA) and activities of SOD, GSH-Px,CAT and iNOS were detected. iNOS mRNA expression was detected by using RT-PCR. Results:VC could decrease mortality and increase survival activity of alveolar macrophages. VC could also decrease ROS,NO and NOS activity,increase SOD,GSH-Px, CAT activities and downregulate the expression of iNOS mRNA. Conclusion:The lipid peroxidation of alveolar macrophage could be induced by Ni2O3. VC could downregulate the expression of iNOS mRNA and reduce the production of ROS and NO through increasing the activity of antioxidative enzymes and antagonize the oxidative damage induced by Ni2O3.

Objective To observing the effects of health education on modified lifestyle and behavior patterns among migrant workers. Methods Individuals from two factories were randomly assigned to the intervention group ( n = 262 ; men 129, women 133 ; mean age 31.8) and the control group ( n = 147 ;men 75, women 72; mean age 31.8). The intervention group received 4-months' health education before changes of awareness of health knowledge, cigarette smoking, alcohol consumption, physical activities,mental health and medical consultation. Results In the intervention group, the awareness of the risk of cigarette smoking and alcohol consumption and normal levels of blood pressure and obesity was significantly improved at 4 months(χ2 =59.65, 47.69, 19.50, and 30. 17; all P＜0. 01 ). However, no significant improvement in awareness of AIDS was found in the intervention group. Of the intervention group, some unfavorable lifestyles and behavior patterns were modified ( cigarette smoking χ2 = 4.50 ; altitude toward clinic visit χ2 = 7.09 ; both P＜0. 05 ). Conclusion Health education could help to improve the awareness of health knowledge and modify lifestyle and behavior patterns of migrant workers.

Objective To study the effects ofautologous bone marrow mononuclear cells (BMMCs)transplantation during coronary artery bypass gafting (CABG) on myocardial infarct size. Methods Forty myocardial infarction patients diagnosed by coronary angiography (CAG) and SPECT and confirmed at surgery were enrolled and randomly assigned CABG alone (group Ⅰ) or CABG with intramyocardial or intracoronary injection of autologous BMMCs (group Ⅱ), 20 cases in each group. Baseline and followed up evaluations included SPECT and NYHA-FC before and after 6 months operation, recorded the major adverse cardiac events (MACE) at the same time. The number of autologous BMMCs injected was (6.84 ± 2.88) ×107 in group Ⅱ. Results There was no procedure-related complication during 6 months followed up in all patients. After 6 months operation,left ventricular ejection fraction in group Ⅱ was significantly higher than that in group Ⅰ [(57.40 ±5.21)% vs. (50.75 ±5.88)%,t =3.79,P＜0.05],NYHA-FC in group Ⅱ was significantly improved than that in group Ⅰ [(1.30 ± 0.47) grades vs. (1.85 ± 0.59) grades, t = 3.27, P ＜0.05],SPECT showed myocardial infarct size in group Ⅱ was significantly lower than that in group Ⅰ[(14.57 ±5.20)% vs. (20.45 ±5.18)% ,P ＜0.05]. Conclusion Autologous BMMCs transplantation during CABG is safe and feasible, which can reduce the myocardial infarct size in patients with myocardial infarction.
