[Method] Eighteen mid-season hybrid rice cultivators approved recently were taken as materials and relationship of plant characters including bud living rate and moth- er stem emergence rate of ratoon rice before harvest was explored, based on relat- ed data. [Result] The shorter rice with lower harvesting index is the main character of high emergence rate for first cropping rice; decline of plant height and increase of ear-bearing percentage would improve emergence of regenerative seedlings. [Conclusion] The research provided scientific reference for breeding of rice cultivars with high regenerative capacity.展开更多

Nonoclonal antibody specifically against PRL-3, 3B6, was obtained with hybridoma technique.RESULTS： Positive PRL-3 expression was detected in 43.3% （227 of 293） of gastric cancer cases. High expression of PRL-3 was positively correlated with tumor size, depth of invasion, vascular/lymphatic invasion, lymph node metastasis, high TNM stage and tumor recurrence. Patients with positive PRL-3 expression had a significantly lower 5-year survival rate than those with negative expression （28.3% vs 52.9%, P 〈 0.0001）. Patients who received curative surgery, and with positive PRL-3 expression had a significant shorter overall survival and disease-free disadvantage over patients with negative expression （hazard ratio of 16.7 and 16.6, respectively; P 〈 0.0001 for both）. Multivariate analysis revealed that PRL-3 expression was an independent prognostic indicator for overall and disease-free survival of gastric cancer patients, particularly for survival in TNM stage Ⅲ patients. CONCLUSION： PRL-3 expression is a new independent prognostic indicator to predict the potential of recurrence and survival in patients with gastric cancer at the time of tumor resection,展开更多

The second is to explore the flower forcing peony after anthesis regeneration technique. The main research results： comprehensive gibberellin peony flower induction of morphological and physiological indexes, such as gibberellin concentration of 150 mgFL and 200 mg/L the effect of flower induction was better than the other treatments; gibberelin （GA3） breaking the dormancy of the peony to blossom ahead of time has the promoter action, also has certain effect on nutritional growth; to premature flowering the abscisic acid （ABA） has opposite effect; whereas auxin （IAA） and corn （ZT） effect was not obvious; rejuvenation results showed that after a year of conservation and managemental measures, flower induction after the flower of peony played a very important role in the restoration. After the winter flower induction, peony flowerpot of soil hardening, through the soil replacement, repair of roots, flower peony recovery showed a very significant effect.展开更多

There was a significant correlation between TNF-αand IL-6 （P〈0.001）.CONCLUSION This research into the effects of the proinflammatory cytokines on liver transplantation has provided new insights into the mechanisms of ischemia and reperfusion injury to OLT.展开更多
