Culture conditions and extracellular enzyme activities were optimized. The growth curves of the strains were determined to study mycelium dry weight and protein content changes. Gas chromatography and infrared spectroscopy were used to detect changes of functional groups before and after the action of the fungi on the model compounds. Possible decomposition products and degrada-tion mechanisms were proposed. The research findings show that C. Versicolor and Golden Mushroom can grow in presence of the model compounds. The optimum culture conditions were a pH of 6.0, a carbon-nitrogen ratio of five and a Tween-80 concentration of 0.1%. Newly produced substances were found by gas chromatography. Infrared analysis showed that the model compounds degraded under the action of the microorganisms.展开更多

Methods Databases articles about YYHT in treating IgAN patients were searched through February 2018. Comparisons were YYHT alone or YYHT in combination with western medicine as experimental intervention, and western medicine as the control. Randomized controlled trials (RCTs) were selected. Cochrane collaboration tool was used for assessing risk of bias to evaluate methodologies. RevMan 5.3 software was applied to analyze the data of included trials. Results A total of 21 studies involving 1473 patients were included. Meta-analysis results demonstrated that YYHT alone or YYHT in combination with western medicine were more efficacious than only western medicine in decreasing proteinuria [MD =-0.41, 95% CI (-0.53,-0.29), P < 0.00001] and the urine red blood cells [MD =-7.46, 95% CI (-9.28,-5.64), P < 0.00001]. There also showed improvement in the clinical total effective rate [OR = 2.78, 95% CI (2.14, 3.61), P < 0.00001] between the two groups. Some of the included trials did not report the adverse events. Conclusions Current evidence shows that YYHT can reduce proteinuria and urine red blood cells and improve the total efficacy rate. Since poor quality and publication bias of some included trials, more evidence-based medicine studies needed to define the role of YYHT in the treatment of IgAN.展开更多

Methods： Searching the randomized controlled trials （RCT） studies from the databases （China HowNet database, Wan Fang database, VIP database, Master Thesis and Pubmed） between January 2013 and January 2017. RevMan 5.3 software was used to evaluate the quality of these collected papers. Results： Of 48 potentially relevant publications, 10 randomized studies representing 691 patients met inclusion criteria with 369 cases in the supplementing Qi and nourishing Yin plus Chemotherapy group （Herbs ＋ Chem group） and 322 cases in Chemotherapy group （Chem only group）. There were significant differences between Herbs ＋ Chem group and Chem only group in improving the treatment efficacy and reducing the side effects of chemotherapy （P 〈 0.001 for all）. There were also significant differences between the two groups in tumor response and quality of life （P 〈 0.001 for all）. Conclusion： Herbs of supplementing Qi and nourishing Yin may increase chemotherapy effectiveness, reduce chemotherapy toxicity and improve the quality of life of patients with lung cancer when combined with chemotherapy.展开更多
