With homology cloning approaches coupling with RACE (rapid-amplification of cDNA ends) techniques, the full-length coding sequence of pathogenesis-related protein PR10-1 with differential expression was cloned from the total RNA of the root of Panax notoginseng, and its function was explored furtherly. As a result, the longest 465 bp ORF (named as PnPR10-1 with the Accession No. KJ741402 in GenBank) was detected from the cloned sequence with full-length of cDNA of 863 bp. The corresponding peptide encoded consisted of 155 amino acids, contained some domains such as Bet-v-I, and showed high similarity with that from Panax ginseng by analysis of phylogenetic trees created from the alignments. Real-time quantitative PCR showed that the expression of PnPR10-1 gene was constitutive in different tissues of 1-3 year old plant, suggesting that it might be involved in growth, development, and secondary metabolism; yet it was up-regulated significantly with the infection of Fusarium oxysporum in root, suggesting that it might be involved in defense against many diseases including root rot in P. notoginseng.

Objective:To analyze post-discharge coping difficulty of delivery women based on social ecosystem theory.Methods:From March to May 2022, 23 delivery women from Affiliated Hospital of Guilin Medical University were selected as research objects by the purpose sampling method. The phenomenological research method was used to conduct face-to-face semi-structured interview. The content analysis method was used to analyze the data and extract the theme.Results:A total of 3 themes and 11 sub-themes were extracted. The micro level included 1 theme, namely care stress and self recovery problems coexist, including difficulty in breastfeeding, feeling powerless to raise children, anxiety, disturbance in body recovery of delivery women, prominent sense of sleep deprivation, insufficient knowledge of infant care and body recovery. The mesoscopic level included 1 theme, namely changes in life atmosphere, including caregiver relationship conflict, lack of family support and sense of connection. The macro level included 1 theme, namely interaction of social environment, including living environment not meeting expectations, sense of economic burden, expectation of instant professional guidance.Conclusions:The post-discharge coping difficulty of delivery women is complex and varied. Medical staff should use information technology, family synchronous empowerment, social worker intervention and other methods to meet the needs of delivery women, reduce their post-discharge coping difficulties.
