1Effect of Combined Chilling and GA_3 Treatment on Bud Abortion in Forced ‘Luoyanghong' Tree Peony(Paeonia suffruticosa Andr.)显示文摘This research investigated the effect of combined chilling and GA_3 treatment on bud abortion of tree peony under greenhouse conditions to determine the dynamics of exogenous hormones and chilling effects on bud abortion. Research of such nature will increase the understanding of the effects of GA_3 and chilling level on flower development thereby, promoting off-season cultivation techniques in tree peonies to increase production that meets market demand. Hormone and sugar levels in the ‘Luoyanghong' tree peony were respectively determined using High-Performance Liquid Chromatography(HPLC) and spectrophotometer. Non-potted chilling with 200 mg·L^(-1) GA_3 treatment reduced bud abortion rate. Flowering rate in non-potted chilling with 200 mg·L^(-1) GA_3 plants was 58%, as against 21% in potted chilling plants with 200 mg·L^(-1) GA_3 treatment. Sugar accumulation in retained or aborted flower buds was conversely related to ABA level. Low ABA and high sugar levels were noted in retained buds whereas the reverse induced bud abortion. ABA level apparently inhibited sucrose and reducing sugar uptake in aborted buds whereas GA_3 enhanced sucrose uptake in retained buds. GA_3 and IAA levels were higher in retained than in aborted buds, which made plants with retained bud more competitive in nutrient uptake(by root)for growth and development. Overall, combined chilling and GA_3 treatment enhanced plant growth and development, particularly bud sprouting, growth and flowering.MORNYA Philip M.P.

2Nano-selenium controlled cadmium accumulation and improved photosynthesis in indica rice cultivated in lead and cadmium combined paddy soils显示文摘Selenium nanoparticles(Se NPs) are less toxic and more biocompatible than selenite or selenate. However, studies involving spraying with Se NPs for reducing accumulation of cadmium(Cd) and lead(Pb) in rice grains have been rarely reported as yet. Herein, indica rice seedlings cultivated in Cd + Pb-spiked paddy soils(denoted as positive control) were sprayed with Se NPs sols for four times from tillering to booting stage. Compared to positive control, 50–100 μmol/L Se NPs downregulated Cd transporters-related genes such as Os LCT 1, OsH MA 2 and Os CCX2 in leaves and OsLCT1, Os PCR1 and Os CCX2 genes in node I at filling stage. Meanwhile, Se-binding protein 1 was distinctly elevated, involving the repression of Cd and Pb transportation to rice grains. Se NPs also differentially improved RuBP carboxylase and chlorophylls especially some key genes and proteins involving photosynthetic system. Besides, 25–50 μmol/L Se NPs diminished reactive oxygen species overproduction from NADPH oxidases whereas boosted glutathione peroxidase, reducing protein carbonylation in rice seedlings. However, the antioxidant isozymes and oxidatively modified proteins were slightly rebounded at 100 μmol/L. Se contents were noticeably elevated and confirmed to exist as selenomethionine in the rice grains following all the treatments by Se NPs. Thus, the optimal dosage of Se NPs for foliar application is 50 μmol/L, which significantly decreased Cd accumulation, improved photosynthesis and Se enrichment whereas caused no distinct reduction of Pb in the grains. Thus, an appropriate dosage of Se NPs can be conducted to decrease Cd accumulation, improve photosynthesis, and organic Se contents in rice grains.Chengrun Wang Tingting Cheng Haitao Liu Fangyun Zhou JifengZhang Min Zhang Xinya Liu Wenjun Shi Tong Cao 2021Journal of Environmental Sciences2021,33,5:5
3Clinical observation on pericardial effusion in patients with lung cancer treated by intrapericardial catheterization and infusion of highly agglutinative staphylococcin and cisplatin显示文摘Objective: To evaluate the therapeutic efficacy of injecting highly agglutinative staphylococcin (HASL) and cisplatin into pericardial cavity of lung cancer patients with pericardial effusion. Methods: 81 patients were randomized into two groups: 45 in the experimental group (HASL and Cisplatin) and 36 in the control group (Cisplatin). At first pericardial effusion was drained out from a intrapericardial catheter and then different drugs were infused, respectively. 24 h after perfusion the draining continued again until drainage quantity was less than 30 mL every day. The draining lasted 10–15 days. Results: The response rate was 91.1% for the experimental group and 80.6% for the control group. There was no significant difference between the two groups (P>0.05). The complete remission was 77.8% for the experimental group and 52.8% for the control group, which was statistically significant difference (P<0.05). The adverse effects were myelosuppression and nausea and vomiting, which were 35.6% and 40.0% in the experimental group and 72.2% and 66.7% in the control group, respectively (P<0.01, P<0.05). Conclusion: Inject- ing HASL and cisplatin into pericardial cavity may be a better way to control pericardial effusion of lung cancer.Qi'an Jiang Yide Zhou Gui'e Cheng Fangyun Gong Shuyan Zhang Fengping Lang Meihong Zhao 2006The Chinese-German Journal of Clinical Oncology2006,5,5:3
