Metaanalysis of effectiveness of different exercises on inflammatory response in obese adolescents / 中国学校卫生

Objective@#To systematically evaluate effectiveness of exercises on inflammatory response among obese adolescents.@*Methods@#By searching CNKI, PubMed, Web of Science, EBSCOhost and other databases, randomized controlled trials (RCTs) on the influence of different exercises on inflammatory indicators in obese adolescents were collected according to the inclusion and exclusion criteria. Cochrane evaluation tools were conducted methodological studies on the included literature quality evaluation, and RevMan 5.3 analysis software was used for statistical analysis.@*Results@#A total of 21 RCTs were included, involving 1 020 subjects. The results of Meta analysis showed that aerobic training (AT) and aerobic plus resistance training (AT+RT) could significantly reduce BMI, serum C reactive protein (CRP) and leptin levels in obese adolescents. In addition, the effects of AT+RT on pro inflammatory CRP ( MD=-0.52, 95%CI=-0.75--0.30, P <0.01), leptin ( MD=-7.20, 95%CI=-10.45--3.94, P <0.01) and anti inflammatory adiponectin ( MD=1.28, 95%CI=1.01-1.55, P <0.01) were stronger than AT. High intensity interval training (HIIT) was associated with BMI reduction ( MD=-1.14, 95%CI=-1.92--0.36, P <0.01) and increased adiponectin in obese adolescents ( MD=1.79, 95%CI=1.09-2.50, P <0.01), and HIIT was superior in improving adiponectin level in obese adolescents than AT and AT+RT.@*Conclusion@#Long term and regular AT, AT+RT and HIIT can reduce inflammation in obese adolescents. HIIT is a notable exercise method for obese adolescents to resist inflammation.

Cluster analysis on hypocrellin A content in anamorphs of Shiraia bambusicola / 中国中药杂志

<p><b>OBJECTIVE</b>By examining the colony growth rate, colony texture, substrate mycelium color and separation method of 40 anamorph strains of Shiraia bambusicola to investigate the relationship between these indexes and content of hypocrellin A.</p><p><b>METHOD</b>In UV-spectrophotometry and microscopic observation were applied in the experiments. The results were analyzed by the clustering and variance analysis.</p><p><b>RESULT</b>SPSS clustering analysis showed that the colony characters of S. bambusicola anamorph strains had significant differences with hypocrellin A content.</p><p><b>CONCLUSION</b>In the tested conditions, substrate mycelium color of S. bambusicola anamophs has the most distinct correlation with the yield of hypocrellin A.</p>

Isolation and determination of anamorph of Shiraia bambusicola / 中国中药杂志

<p><b>OBJECTIVE</b>To isolate and identify the anamorph of Shiraia bambusicola.</p><p><b>METHOD</b>Fungus strains were isolated from mature ascospores and stroma. They were identified by means of morphological identification including colony and microscope characteristic, the molecular identification was done by 5.8S-ITS rDNA.</p><p><b>RESULT</b>The strains GZDXIFR-171 and GZDXIFR-181 were isolated and obtained with the separation of different methods, which had the same colony morphology. With the universal primers of the ITS1-5.8S rDNA-ITS2, the 5.8S-ITS rDNA sequence of GZDXIFR-171 and GZDXIFR-181 were obtained by the PCR amplification and sequencing. Compared with the published nucleotide sequence of 5.8S-ITS rDNA in NCBI (National Center for Biotechnology Information), GZDXIFR-171 and GZDXIFR-181 were highly identical with S. bambusicola.</p><p><b>CONCLUSION</b>The isolated strains GZDXIFR-171 and GZDXIFR-181 were confirmed to be the true anamorph of S. bambusicola.</p>
