Moral Defense for Ethical Review of Medical Technology Clinical Admittance / 中国医学伦理学

This paper discussed the main point specifically from the three aspects which are the certainty and uncertainty of technological function , the predictability and unpredictability of technological efficiency , and“should do”or“not should do”of technological application .It presented an ethics argument of medical technology clinical admittance restriction and defends the standpoint -what we can do does not mean what we should do , aiming to provide moral theoretical support of ethical review of medical technology application .

Enrichment and Molecular Characterization of a Bacterial Culture Involved in Lysis of Microcystis aeruginosa / 微生物学通报

An enrichment culture showing specific algae-lysing activity was isolated from the mixtures of different samples and Microcystis aeruginosa. The process of algal lysis was monitored by chlorophyll measurement, PCR, and denaturing gradient gel electrophoresis (DGGE). The result showed that the enrichment culture had still high algicidal activity against M. aeruginosa after 1/100000 dilution. Rubritepida sp. C1, Pseudomonas sp. C2 and Sphingomonas sp. C3, as accompanying bacteria, existed in M.aeruginosa. The bacterial community in M. aeruginosa showed significant change after adding the enrichment culture, where uncultured Flavorbacterium sp. A2, Sphingomonas sp. C3 and Hydrogenophaga sp. A3 were observed, and A2 became a dominant species. The obvious correlation can be seen between change of bacterial population and extinction of M. aeruginosa. Compared identification of pure bacterium with sequencing of DGGE band, it was inferred that uncultured bacteria were probably play an important role in controlling the growth and abundance of M. aeruginosa.

Establishment of Ethical Assessment System in the Admittance of the Limitative Medical Technologies / 中国医学伦理学

Objective to establish an ethical assessment system in the admittance of the limitative medical technologies.Method:literature review and Delphi method are employed to adjust and set the structure,index numbers,and index weights of ethical assessment system of the limitative medical technologies.Result:An ethical assessment system in the admittance of the limitative medical technologies was established,which included 3 primary indices,11 secondary indices and 35 tertiary indices.There were 4 qualitative levels with different weights in tertiary indices,based on which the global grade and proposed-admittance criterion were obtained.Conclusion:Establishment of ethical assessment system in the admittance of the limitative medical technologies provides an ethical evidence for the assessment of clinical admittance of the limitative medical technologies with qualitative and quantitative approaches and class-setting evidence.
