BACKGROUND: MicroRNAs (miRNAs) play a key role in various biological processes by influencing the translation of target messenger RNAs (mRNAs) through post‐transcriptional regulation. The miR‐184‐3p has been identified as an abundant conserved miRNA in insects. However, less is known about its functions in insect–plant virus interactions. RESULTS: The function of miR‐184‐3p in regulation of plant viral infection in insects was investigated using a rice black‐streaked dwarf virus (RBSDV) and Laodelphax striatellus (Fallén) interaction system. We found that the expression of miR‐184‐3p increased in L. striatellus after RBSDV infection. Injection of miR‐184‐3p mimics increased RBSDV accumulation, while treatment with miR‐184‐3p antagomirs inhibits the viral accumulation in L. striatellus. Ken, a zinc finger protein, was identified as a target of miR‐184‐3p. Knockdown of Ken increased the virus accumulation and promoted RBSDV transmission by L. striatellus. CONCLUSION: This study demonstrates that RBSDV infection induces the expression of miR‐184‐3p in its insect vector L. striatellus. The miR‐184‐3p targets Ken to promote RBSDV accumulation and transmission. These findings provide a new insight into the function of the miRNAs in regulating plant viral infection in its insect vector. © 2023 Society of Chemical Industry. [ABSTRACT FROM AUTHOR]

Background: Allogeneic hematopoietic stem cell transplantation stands as a vital treatment for leukemia, yet its implementation poses considerable challenges and complications. A comprehensive understanding of these challenges is crucial for appreciating the significance of enhanced nursing care., Objective: To explore and summarise the nursing experience of allogeneic haematopoietic stem cell transplantation for acute lymphoblastic leukaemia. The significance of this objective lies in the potential transformative impact that enhanced nursing care can have on overall patient outcomes within the context of allogeneic hematopoietic stem cell transplantation., Methods: Patients with acute lymphoblastic leukaemia treated with allogeneic haematopoietic stem cell transplantation in our hospital between August 2020 and January 2022 were recruited for this study. A total of 50 patients who met the complete inclusion criteria were enrolled and included in this study. Patients in the traditional group were given traditional nursing interventions, while patients in the exploration group were offered individualized interventions according to their personalized plans. In the traditional group, standard nursing care involved routine health education, vital signs monitoring, and sterile care in a laminar flow ward. Post-transplantation changes were observed, and patients were encouraged to engage in suitable exercises. The exploration group received enhanced infection control measures, including regular disinfection and cleaning of patient wards. Individualized care plans, collaborative chemotherapy consultations, and extensive patient and family education were implemented. Clinical data of all patients were collected, and their nursing experience was summarized and analyzed by comparing the incidence of adverse reactions and evaluating nursing satisfaction., Results: The analysis group demonstrated a significantly lower incidence of adverse reactions compared to the traditional group. Specifically, the total adverse reaction rate in the analysis group was 8.00%, markedly lower than the traditional group's 48.00% (P < .05). Moreover, patient satisfaction in the exploration group was significantly higher than that observed in the traditional group (P < .05). In detail, the satisfaction level in the exploration group reached 92.67%, while the traditional group reported a satisfaction level of 77.56%., Conclusion: For patients with acute lymphoblastic leukaemia who received allogeneic haematopoietic stem cell transplantation, a personalized care intervention plan involving careful primary nursing, full protection and enhanced psychological care can It can effectively improve the adverse effects of sleep, thus increasing their satisfaction with nursing.
