Objective To investigate the effects of dexmedetomidine preconditioning on nitric oxide (NO)/endothelin (ET)-1 imbalance and remote lung injury induced by lower limb ischemia-reperfusion (LIR). Methods Sixty patients who scheduled for unilateral lower extremity surgery matched American Society of Anesthesiologists (ASA) Ⅰ-Ⅱ, were randomized into two groups:control group (R group, n=30) and dexmedetomidine preconditioning group (PD group, n=30). Lumbar plexus combined with sciatic nerve block was performed guided by a nerve stimulator in both groups. In group PD, dexmedetomidine intravenous infusion was started at a dose of 0.125 mL/kg (4 mg/L) for 10 minutes before using tourniquet, whereas group R received an equivalent volume of normal saline. Artery blood gas analysis, respiratory index and oxygenation index were measured, and NO, ET-1, interleukin-8 (IL-8) and malondialdehyde (MDA) concentrations were determined from plasma samples 10 minutes before tourniquet inflation (T0), 15 minutes (T1), 2 h (T2), 6 h (T3) and 24 h (T4) after tourniquet deflation. Results Compared with T0, RI was higher at T3 in group R and OI was lower at T2-4 (P＜0.01). There were no significant differences in RI and OI of group PD between different time points (P＞0.05). In R and PD groups, ET-1, IL-8 and MDA concentrations were increased, while NO level and NO/ET-1 ratio were significantly decreased after tourniquet deflation (P＜0.05). Compared with group R, RI was lower and OI was higher at T3 in group PD (P＜0.01). The levels of ET-1, IL-8, MDA, NO and NO/ET-1 ratio were significantly different after tourniquet deflation between group PD and group R (P＜0.05). In group R, there was positive correlation between ET-1 and IL-8 levels with RI, and negative correlation between ET-1 and IL-8 levels with OI (P＜0.01). There was positive correlation between NO level, NO/ET-1 ratio and RI level (P＜0.01). Conclusion Lung function impairment induced by tourniquet application could be attenuated by dexmedetomidine preconditioning based on protecting endothelial cells and inhibiting lipid peroxidation.

Objective By studying the prescriptions and medicines for treating rheumatoid arthritis (RA) prescribed by modem doctors, we tried to provide new ideas for developing the new medicines for treating rheumatoid arthritis. Methods 340 prescriptions on treating rheumatoid arthritis were collected from core medical periodicals and books published in the recent 20 years. Make a statistical analysis to the medicines in these prescriptions according to TCM etiological and pharmaceutical theories and modern researching foundlings. Results Among all 254 Chinese medicines used for treating RA, 32 medicines belong to worm and vine medicines, being used for 806 times. Conclusion The worm and vine medicines are frequently used in treating RA with good therapeutic effects combined with other kinds of medicines.

OBJECTIVETo perform a transcriptomics study in differential genes after Xianglian External Lotion (XEL) induced the recovery of drug-resistant Candida albicans strains sensitive to Fluconazole.

METHODSBroth microdilution antifungal susceptibility test was used to detect minimal inhibitory concentration (MIC) of drug-resistant Candida albicans strains induced by XEL. Transcriptome sequencing (RNA-Seq) was used to determine and compare the transcription of primary drug-resistant Candida aIbicans strains and sensitive strains induced by XEL. High expressed genes and signaling pathways strains were analyzed by gene ontology (GO) method.

RESULTSXEL could induce drug-resistant strains of the 6th generations to recover sensitivity. Transcriptome sequencing showed that, as compared with primary drug-resistant strains, there were 165 genes with up-regulated RPKM index and 144 genes with down-regulated RPKM index after XEL induction. GO analyses found that all genes were mainly classified as GO:0015903 (fluconazole transport).

CONCLUSIONSXEL could induce the recovery of drug-resistant Candida albicans strains sensitive to Fluconazole. By analyzing transcriptomes, authors speculated that XEL could recover strain sensitivity to fluconazole by opening fluconazole transport pathway.
