A Set of Artificial Pollination Technical Measures: Improved Seed Yields and Active Ingredients of Seeds in Oil Tree Peonies.

The tree peony, a novel woody oil crop extensively cultivated in China, necessitates further investigation into artificial pollination technology to enhance seed yield. In this study, we conducted artificial pollination experiments with 6-year-old Paeonia ostii 'Feng Dan' seedings for suitable pollen sources, pollen concentration, pollination timing, and pollination frequency. By evaluating seed yields, active ingredients, and oil quality, we derived the following significant conclusions. Firstly, compared to natural pollination, artificial pollination could significantly increase the fruit diameter by 13.94-27.58%, seed yields by 35.17-58.99%, and oil content by 6.45-7.52% in tree peonies. In active ingredients, seeds produced by pollen from Hantai County significantly enhanced starch content (by 48.64%), total phenols (by 41.18%) and antioxidant capacity (by 54.39%). In oil quality, seeds produced by pollen from Heyang County exhibited the highest α-linolenic acid and total fatty acid content with enhancements of 1.68%, 7.41%, and 8.48%. Secondly, hand pollination with pure pollen significantly increased seed yield by 58.99%, total phenol content by 40.97%, antioxidant capacity by 54.39%, and oil content by 1.53% compared to natural pollination. Thirdly, pollination at 2/3 bloom range significantly increased seed number by 63.08% and yield by 45.61% compared to natural pollination. Finally, the effect of one, two, and three pollination events had no difference in seed yield. So, to summarize, applying a 100% concentration of allochthonous pollen once is recommended when the bloom range is more than two thirds.

Quality of Life Among Chinese Child Survivors of Heart Failure After Discharge From Pediatric Intensive Care Unit.

INTRODUCTION: This study investigated the current quality of life (QOL) status and related influencing factors in children with heart failure in the pediatric intensive care unit (PICU). METHOD: One hundred eighty-three children admitted to the PICU with heart failure were consecutively sampled. They were assessed 3 months after discharge and compared with a control group of 160 healthy individuals. The Pediatric Quality of Life Inventory (version 4.0) and Children's Revised Impact of Event Scale were completed, and factors influencing QOL were analyzed. RESULTS: Three months after discharge, the PICU group reported lower average scores on the overall QOL and the physical and emotional functioning scales than the control group. In particular, posttraumatic stress disorder status, age, and caregiver educational level greatly influenced the PICU children's QOL. DISCUSSION: More interventions and attention are needed to improve the QOL for PICU heart failure patients after discharge.

Effect of intensive care unit diary on incidence of posttraumatic stress disorder, anxiety, and depression of adult intensive care unit survivors: A systematic review and meta-analysis.

AIM: To systematically evaluate the effect of intensive care unit diary psychotherapy on the incidence of posttraumatic stress disorder, anxiety, and depression after discharge from intensive care unit. BACKGROUND: Many studies have reported the potential advantages and risks of intensive care unit diary psychotherapy in adult patients discharged from intensive care unit, but the results are divergent. DESIGN: Systematic review and meta-analysis of prospective randomized controlled or case-controlled studies. DATA SOURCE: Databases such as Cochran Library, Pubmed, Embase, CINAHL, and ProQuest databases, China national knowledge infrastructure (CNKI) were searched for literatures published from January 2000-March 2020. REVIEW METHODS: We use the Cochrane Risk of Bias Tool for quality assessment and audit manager 5.3 software for meta-analysis. The main result is the incidence of posttraumatic stress disorder, anxiety, and depression. RESULTS: Ten studies meeting the inclusion criteria were identified, including eight randomized controlled studies and two case-controlled studies, with a total of 1,210 patients. The pooled results of this meta-analysis indicated that the intensive care unit diary could reduce the incidence of posttraumatic stress disorder, anxiety, and depression. CONCLUSION: This study showed that an intensive care unit diary could improve the psychological symptoms of adult intensive care unit patients after discharge. However, due to limitations such as publication bias and case sample size, the results should be carefully considered. Researchers need to further clarify the multidisciplinary collaborative process of intensive care unit diary therapy, the real beneficiaries, and its impact on family members' psychological status by conducting large, robust studies in the future. IMPACT: This study's findings suggest that medical staff need to re-examine the role of intensive care unit diary therapy, its standardized implementation and provide effective intervention for reducing psychological stress-related symptoms of intensive care unit patients after discharge.

Psychosocial Assessment of Donors in Pediatric Living Donor Liver Transplantation: A Systematic Review.

BACKGROUND: Pediatric living donor liver transplantation (LDLT) is the only way to save children with end-stage liver disease. The donor for liver transplantation (LT) may have a complicated psychosocial condition. PURPOSE: This review aims to identify the domains of the donor psychosocial questions that should be addressed and summarize the aspects and tools future psychosocial assessments should include. METHODS: We searched the PubMed, Medline, Cochrane Library, Embase, Web of Science, and Google Scholar databases for the terms pediatric, liver transplantation, donor, and psychosocial. We used the Joanna Briggs Institute Critical Appraisal Tool to appraise reporting quality. Two researchers independently selected the papers and performed data extraction and quality appraisal. RESULTS: The articles included in this review contain 26 quantitative studies and 2 qualitative studies. The study quality was moderate to high. Donors have ambivalence, anxiety, the need for family and social support, the need for adequate information, distress, and low self-esteem during the preoperative period. In the postoperative period they have poor psychological condition, panic disorder, conversion disorder and substance use/abuse disorder, abnormal family functioning, better psychosocial outcome, or among others. The assessment methods consisted of the questionnaire survey and semi-structured interview. Among the 28 studies, 17 different psychosocial domains were mentioned. The most frequently referred to was family and social support. CONCLUSION: The contents of the psychosocial assessment must include anxiety or depression, family and social support, ambivalence, information, and positive psychosocial characteristics. Assessment methods should use the questionnaire survey and semi-structured interview. According to this review, future research can develop a specific psychosocial assessment tool for pediatric LT donors.
