Project description:Treatment options and reliable predictive marker to determine patients at risk to develop postoperative LD and to define the optimal time point of liver resection are limited. Accordingly, there is an urgent need for an easily assessable preoperative test to predict postoperative liver function recovery, specifically as current markers are often expensive, time consuming and sometimes invasive. Emerging evidence suggests that microRNA (miRNA) signatures represent potent diagnostic, prognostic and treatment response biomarkers for several diseases. Using next-generation sequencing as an unbiased systematic approach 554 miRNAs were detected in preoperative plasma of 21 patients suffering from postoperative LD after liver resection and 27 matched controls. Subsequently, we identified a miRNA signature - consisting of miRNAs 151a-5p, 192-5p and 122-5p - that highly correlated with patients developing postoperative LD after liver resection. The predictive potential for postoperative LD was subsequently confirmed using real-time PCR in an independent validation cohort of 98 patients. Ultimately, a regression model of the two miRNA ratios 151a-5p to 192-5p and 122-5p to 151a-5p was found to reliably predict postoperative LD, severe morbidity, prolonged intensive care unit and hospital stay and even mortality prior to surgery with a remarkable accuracy, thereby outperforming established markers of postoperative LD. Ultimately, we documented that miRNA ratios closely followed liver function recovery after partial hepatectomy. Conclusion: Given the clinical relevance of predicting potentially fatal postoperative clinical outcome after liver resection, our data demonstrate the clinical utility of a novel miRNA-based biomarker to support the selection of patients undergoing partial hepatectomy. The dynamical changes during liver function recovery indicate a possible role in tailoring the optimal time point of surgery to each individual patient. Thereby, our data might help to tailor surgical strategies to the specific risk profile of individual patients.

Project description:The electroacupuncture-induced analgesic effect has been used widely to alleviate diverse pains. However, significant individual variations in analgesic effect of EA for both experiments and clinics were reported. According to the sensitivity of the analgesic response to EA stimulation, the subjects could be categorized into high responders (HR) and low responders (LR). However, the molecular mechanism of individual variability in the analgesic response to acupuncture stimulation is still uncertain. This study aims to investigate the potential gene expression in spinal dorsal horn induced by 2Hz/100Hz electroacupuncture in HR and LR rats. Rats were given 2Hz or 100Hz electroacupuncture for 30 min and using cDNA microarrays to compare different gene expression in dorsal horn. Transcriptome profiling analysis found that some co-regulated genes related with electroacupuncture or 2Hz or 100Hz freqencies. These co-regulated genes were plasticity-related by GO analysis. We also found some special regulated genes in HR vs. LR in 2Hz/100Hz electroacupuncture stimulation. These results suggested that neurotransmitter system and cytokine different between HR with LR in 2Hz electroacupuncture. But in 100Hz electroacupunture, there were many different regulated genes related with ribosome between HR with LR, which needs more studies to research the function and may play an important role in HR vs. LR by 100Hz electroacupuncture. Keywords: Transcriptome analysis Rats were exposed to different frequencies (2Hz or 100Hz) electroacupuncture stimlation for 30 min and nociceptive testing and returned to home cages for 1 hours before sacrificed. According to the sensitivity of the analgesic response to 2Hz or 100Hz EA stimulation, the rats divided into four groups: 2Hz-HR group, 2Hz-LR group, 100Hz-HR group and 100Hz-LR group. Subsequently analyzed their dorsal horn transcript profile using cDNA microarrays, the rats were without receiving electroacupuncture as control. The tissue of dorsal horn (DH) of the fifth and sixth lumbar (L5 and L6) of four or five rats were selected for transcript analysis in each group. The five control rats were mixed and labeled with cy5, each rat of experiment groups was labeled with cy3.
