The results showed that Wnt5a gene expression level was the highest in Jinhua （JHP） pigs, followed by Zhongbai （ZBP）, DurocxZhongbai （DZB）, and Duroc×Yorkshire×Landrace （DYL） pigs, with significant differences between ZBP, DZB, and DYL （P〈0.05）. This genotypic order was reversed for Wnt7a, Wnt10b, and Wnt11 expression, with JHP and DYL having the lowest and highest expressive levels, respectively. Wnt5a expression was negatively correlated with pH,5 min and ApH （P〈0.01）, some glycolytic markers （P〈0.05）, and positively correlated with meat color （a＊）, shear force （SF） value （P〈0.05）, myosion heavy chain （MyHC） I mRNA proportion （P〈0.01）, turnover ratio of creatine phosphate （CP）, and creatine kinase （CK） activity （P〈0.05）. Opposite correlations were observed for Writ2, Wnt7a, Wnt10b, and Wnt11. These results revealed that Wnt5a, Wnt7a, Wnt10b, and Wnt11 gene expressions in adult porcine muscle contributed to differences between porcine genotypes and affected pork quality. Wnt5a gene expression could be beneficial for the formation of high quality pork by regulating muscle fiber types and postmortem energy metabolism.展开更多

Observation parameters were included numerical rating scale(NRS) scores,analgesic efficacy, initiation effective time, persistent analgesic time, equivalent morphine dose,National Comprehensive Cancer Network(NCCN)grade in Impact of Pain Measurement Scores, and safety and satisfaction extent investigation.RESULTS: NRS scores and NCCN grade in Impact of Pain Measurement Scores decreased significantly after 5-days' treatment in the two groups(P <0.0001). Compared to the control group, initiation effective time was significantly shorter(P < 0.05)and persistent analgesic time was significantly longer(P < 0.01), equivalent oral morphine doses of the first day and the whole treatment course were significantly decreased in the TKXO treatment group(P < 0.01 or P < 0.05). No obvious adverse effects were found in the TKXO group.CONCLUSION: TKXO combined with opioid analgesics possesses the advantages of high efficacy,fast action, long persistent action, safety and convenience in use, and it can reduce the dose of opioid.展开更多
