In the present study, using specific antibody against D1 protein, we detected four ag- gregates of D1 protein in thylakoid membranes from spinach leaves illuminated at high light (800―2500 μmol photons·m?2·s?1) for 3 h. Their accumulations were dependent on the light intensity to which the leaves had been subjected. Further immunoblot analysis indicated that 70 kD aggregate was a prod- uct of D1 protein cross-linked with CP43, 65 and 60 kD aggregate were two cross-linked products be- tween D1 and D2 proteins, and 41 kD aggregate was one cross-linked D1 with α-subunit of cytochrome b559 (Cyt b559). This result provided the evidence for the existence of the aggregation of the D1 protein in vivo. The maximal level of D1/Cyt b559 aggregate occurred at 1000 μmol photons·m?2·s?1 but drastically decreased with further increasing light intensity. Im- munoblot analysis with phosphothreonine (Thr (P)) antibody indicated that D1/CP43 and D1/Cyt b559 aggregates contained the phosphorylated protein(s). In vitro dephosphorylation experiment also showed that D1/Cyt b559 and D1/CP43 aggregates lost the immunoreactivity with Thr (P) antibody after the phosphatase treatment of the membranes from high-light-illuminated leaves. Our results demon- strated that strong illumination of spinach leaves in- duced cross-linked products of D1 protein with its nearby polypeptides of PS Ⅱ , some of which con- tained the phosphorylated D1 protein.

Objective: To investigate the impact of excellent event management in improving patient safety and nursing staff care satisfaction. Methods: The study was analyzed by retrospective comparison, and routine management from January 2022 to December 2022 was set as the control group, and excellent event management from January 2023 to January 2024 was set as the study group. The differences in nursing outcomes between both groups were compared. Results: The rate of adverse events in the study group (0.61%) was lower than that in the control group (0.96%), and the rate of excellent events in the study group (2.57%) was higher than that in the control group (0.97%) (P < 0.05). Meanwhile, the satisfaction level of nursing safety in the study group reached 98.81%, which was much higher than in the control group (92.21%) (P < 0.05). Conclusion: Nursing excellent event management had a positive impact on improving patient care safety satisfaction, reducing the rate of adverse events, and increasing the rate of reporting excellent events.

According to different planting test data,meteorological data,field planting survey and expert interview data in recent years,frost prevention and drought resistance effect of potato under different planting methods were studied using agro-meteorological disaster risk index analysis method. The results showed that the risk index of potato with the full-film planting was small due to good thermal insulation and soil moisture conservation performance. The risk index of potato with half-film planting( flat mulching,ridging planting and furrow planting) was moderate,while that of ridge tillage without mulching,double rows,full of stars and flat planting was large,and their frost prevention and drought resistance effect were poor. It provides support and reference for understanding the frost and drought conditions of potatoes under different planting methods and carrying out insurance weather services for farmers and production managers.
