RESUMO
The use of beneficial microbes as inoculants able to improve fitness, growth and health of plants also in stress conditions is an attractive low-cost and eco-friendly alternative strategy to harmful chemical inputs. Thirteen potential plant growth-promoting bacteria were isolated from the rhizosphere of wheat plants cultivated under drought stress and nitrogen deficiency. Among these, the two isolates TL8 and TL13 showed multiple plant growth promotion activities as production of indole-3-acetic acid (IAA), siderophores, ammonia, and 1-aminocyclopropane-1-carboxylic acid (ACC) deaminase production, the ability to solubilize phosphate as well as exerted antimicrobial activity against plant pathogens as Botrytis spp. and Phytophthora spp. The two selected strains were identified as Kosakonia pseudosacchari by sequencing of 16S rRNA gene. They resulted also tolerant to abiotic stress and were able to efficiently colonize plant roots as observed in vitro assay under fluorescence microscope. Based on the best PGP properties, the strain K. pseudosacchari TL13 was selected to develop a new microbial based formulate. A sustainable and environmentally friendly process for inoculant production was developed using agro-industrial by-products for microbial growth. Moreover, the application of K. pseudosacchari TL13- based formulates in pot experiment improved growth performance of maize plants.
RESUMO
Objective To develop an Modified Early Warning Score (MEWS) table suitable for professional characteristics and to predict the occurrence of complications in the percutaneous coronary intervention (PCI). Methods This is a retrospective study. PCI patients in catheter room of Qingdao International Center Hospital from July to December, 2015 and July to December, 2016 were selected as the research object. The former was set as the control group, and the latter as the experimental group, traditional MEWS and modified MEWS were applied in the two groups respectively. The incidence of complications were compared between two groups. Results The incidence rates of cardiac arrest, drop of blood pressure, arrhythmia, slow blood flow or no complex flow, perforation, interlayer were 0.83％(3/362), 0.55％ (2/362), 0.55％ (2/362), was 0.55％ (2/362), 2.21％ (8/362) , 4.42％ (16/362) , and were 2.51％(9/358), 5.31％(19/358), 8.66％(31/358) , 3.07％(11/358) , 2.51％(9/358) , 2.79％(10/358) in the control group, the differences were statistically significant (χ2= 4.603-5.302, P<0.05). Conclusions The MEWS score of PCI can be used to predict the occurrence of complications in PCI, and for the patients with MEWS score above 5, they should be given medical and nursing intervention in order to reduce the complications in the operation.
RESUMO
Technical standards were supports that not only for any profession’s development, but also for the basic means of modern quality control.Forensic clinical medicine has developed nearly 40 years in china, there are 23 normative technical documents at present, the range of its application has been expanding with time, the caseload has been more than 1 million pieces per year all the country. Reviewing these standards, it can be seen: Technital standard of forensic clinical medicine has absorbed a large number of advanced international ideas, assimilating plenty of practice experience at the same time, standard's system has been initially formed, it has become one of the important means to guarantee the quality of medicolegal expertise. Certainly, the construction of forensic clinical standardization in China is still an arduous task, there are also many outstanding contradiction in the existing standards, our studies on international standards were not in-depth, and so on. In the future, forensic science experts still need to strengthen the companion study of technical standards and laws or regulations, intensify tracing and evaluating of international standards in order to form more adaptive and advanced technical standards.
RESUMO
The establishment of national medical ethics committee promoted the construction and development of medical ethics regulation,delivered medical ethics declaration,formulated three key regulations of medical ethics,declared three forms of regulations in medical ethics,collected and discussed a series of regulation drafts in medical ethics.
