BACKGROUND: Individual three-dimensional (3D) scaffolds can be constructed by 3D printing via Computer Aided Design based on the given anatomical measurements of related tissues. A rapid and accurate reconstruction of bone, cartilage, muscle and vessel also can be achieved by 3D printing; however, many problems still remain unsolved.OBJECTIVE: To summarize the principle and classification of 3D printing, the classification, characteristics and histocompatibility of scaffolds through reviewing the articles addressing 3D printing applied in bone tissue engineering,thereby providing theoretical foundation for the study on the construction of tissue-engineered bone.METHODS: PubMed and CNKI databases were retrieved for the literatures regarding the application of 3D printing technology in bone tissue engineering published from January 2001 to January 2017 using the keywords of three-dimensional printing, rapid prototyping manufacturing, bone tissue engineering in English and Chinese,respectively. Finally, 30 articles were reviewed and discussed in accordance with the inclusion and exclusion criteria.RESULTS AND CONCLUSION: The microstructures of normal tissues can be reconstructed and seed cells are printed on the 3D scaffolds synchronously by 3D printing technology. Moreover, the scaffold degradation and cell differentiation are synchronous, which contributes to tissue repair. Biological ceramics have been widely used in bone tissue engineering because of its good biocompatibility and mechanical properties. However, the urgent problems such as angiogenesis and cellular signal transduction still need to be addressed.

Objective To understand the performance of the basic medical security system in Guangxi for decision-making support on the development planning of the system during the 12th FiveYear Plan in Guangxi.Methods Descriptive statistics were made to analyze the annual report data of Guangxi's basic medical security system during 2009 to 2011,regarding the basic medical security for urban workers and that for urban residents,as well as those of the new rural cooperative medical system.Results The survey found that the three basic medical security systems in Guangxi have almost achieved full coverage; the compensation ratio keeps rising as the inpatient expenses of urban residents was up to 62.21%,64.96% and 66.96% respectively from 2009 to 2011,and that for urban residents up to 34.26%,39.96% and 49.68% respectively; the ratio for those covered by the new rural cooperative medical system has been maintained at 45% for the three years; the coverage of the systems keeps expanding.Conclusion Recommend to integrate pilots of the three security systems and carry out serious diseases pilot programs; encourage reform of the payment system at institutions at or above county level; reform the risk-pooling of disease management of at primary medical institutions; strengthen the information systems of basic medical insurance system,in an effort to ensure the sound development of the basic medical insurance system.

Objective Through studying the effect of Tangnaikang (TNK) on the expression of Smad 2, 3, 7 mRNA of human renal tubular epithelial cells HK-2 induced by transforming growth factor-β1 (TGF-β1), to explore the mechanism of TNK on prevention and treatment of renal fibrosis. Methods The HK-2 cells were cultured by DMEM/F12 (1∶1) with 10% fetal bovine serum and divided into control group, TGF-β1 group (TGF-β1 10 ng/mL), blank serum control group (TGF-β1 10 ng/mL + 10% animal serum), TNK drug-containing serum therapy groups (TGF-β1 10 ng/mL + 5% TNK or + 10% TNK or + 20% TNK). After 24 h, the expression of Smad 2, 3, 7 mRNA were tested by fluorescence quantitatiye PCR assay. Results After the HK-2 cells were induced by TGF-β1, the expression of Smad 2, 3 mRNA were increased and the expression of Smad 7 mRNA was decreased compared with the control group (P<0.05). The expression of Smad 2, 3 mRNA were decreased and the expression of Smad 7 mRNA was increased in TNK drug-containing serum therapy groups compared with TGF-β1 group (P<0.05), but blank serum control group had no such effect. Conclution TNK could prevent the development of renal fibrosis to some extent through regulating the expression of Smads signaling pathway.

Objective To learn the management staff and funds allocation of the NRCMS in Guangxi,and come up with solution accordingly.Methods Collection of the annual report data of NRCMS in Guangxi from 2009 to 2012,and calculation of the management personnel and funds expenditure.Results The management personnel of NRCMS in Guangxi is found with a 1000-person gap between the actual staffing and approved staffing quota; the management funds rise year by year which come mostly from fiscal appropriation.Yet it accounts for less than 2.00% and with a high rate of surplus; per-capita funds for management personnel rise significantly,along with their per-capital salaries,yet the highest fall below 25000 yuan per year per person.Conclusion Staffing quota should be fixed more rationally to ensure the number and competence of NRCMS management staff; more funds and better use of management funds are required.
