2.Metagenome Cloning—A New Approach for Novel Microbial Bioactive Compounds Discovery
Microbiology 1992;0(01):-
It is reported that more than 95% microbe species non-cultured or un-cultured yet in now days by the traditional cultivation approach, which limits discovering novel bioactive compounds from microorganisms. ‘Metagenome’ is the genomes of the total microbiota found in nature. Metagenome libraries were constructed by directly extracting DNA from environmental sample and transforming to surrogate host. The libraries were screened for novel bioactive compounds or genes surrounding their synthase in different strategies of function-driven or sequence-driven. These have enormously amplified the space of microbial resource utilization and enhanced the opportunity of obtain novel bioactive compounds.

Objective To compare the clinical efficacy of manipulative reduction and splint external fixation and open reduction and internal fixation in the treatment of fractures of the proximal humerus .Methods 62 patients with proximal humeral fractures were randomly divided into the two groups .31 cases in the manipulation group re-ceived manual reduction and splint external fixation;31 patients in the open reduction and internal fixation group were treated by open reduction and internal fixation .The clinical efficacy was compared between the two groups .Results The average healing time of the manual reduction group was (98.34 ±0.42) d,which was shorter than (121.53 ± 0.45)d of open reduction and internal fixation group (t=209.76,P<0.05).The incidence rate of pain in the manu-al reduction group was 22.58%,which was lower than 48.39% in the open reduction and internal fixation group (χ2 =4.51,P<0.05).The excellent and good rate of the manual reduction group was 96.77%,which was higher than 80.65%of the open reduction and internal fixation group (χ2 =4.03,P<0.05).Conclusion The clinical curative effect of manual reduction and splint external fixation in the treatment of proximal humerus fractures is better than open reduction and internal fixation ,it is a reliable choice for treatment of fractures of the proximal humerus .
8.Advances in inflammasome and inflammasome-related diseases
Chinese Journal of Immunology 2015;(6):721-727
Inflammasomes are multi-protein complexes that trigger the activation of caspase-1 and the maturation of interleukin-1β ( IL-1β) , which are critical for inflammation and control of pathogen infection. Inflammasomes are involved in and regulate diversified diseases due to its capability to sense multiple danger signals. In this review, we present the activation and regulation mechanisms for different inflammasomes and discuss how genetic mutations in inflammasome-related genes or abnormal activity of in-flammasomes lead to diseases. Insights into the role of inflammasome in various human diseases will provide sound theoretical basis and effective treatment strategy for these disease.
