OBJECTIVE To study the strategies for treatment,nursing and prevention of monkeypox so as to opti-mize the nursing practice and improve the prognosis of patients.METHODS A total of 4 patients with monkeypox who were treated in the Fifth Affiliated Hospital,SunYat-sen University in Jul.2023 were enrolled in the study.The clinical data and results of laboratory tests and nursing evaluation were collected from the patients.The comprehensive nursing strategies were carried out for the nursing of monkeypox skin pustules,observation of complications,psychological support and control of hospital-acquired infections.RESULTS No secondary skin in-fections or complications occurred among the patients during the hospital stay after the multiple nursing strategies,including skin nursing,prevention of complications,psychological support and control of infections,were carried out for the patients,the condition of anxiety and depression was improved,and hospital-acquired cross-infections did not occur.CONCLUSIONS The nursing of monkeypox involves multiple aspects,the secondary skin infections and ocular complications are the common problems,to which close attention should be paid and standard-ized nursing should be carried out.The psychological support is extremely important for the populations that are vulnera-ble to be stigmatized such as men who have sex with men(MSM)and human immunodeficiency virus(HIV)infection.The psychological interventions such as mindfulness therapy show great potential in relieving the anxiety and de-pression.In addition,rigid infection control measures,including early identification,epidemiological survey and medical separation,can effectively reduce the risk of hospital-acquired transmission.Future studies should be focused on explora-tion of individualized nursing strategies targeting certain populations and development of evidence-based nursing guidelines so as to raise the nursing quality,improve the prognosis of the patients and effectively respond to the challenge.

Carotenoid cleavage dioxygenase (CCD) family is important for production of volatile aromatic compounds and synthesis of plant hormones. To explore the biological functions and gene expression patterns of CsCCD gene family in tea plant, genome-wide identification of CsCCD gene family was performed. The gene structures, conserved motifs, chromosome locations, protein physicochemical properties, evolutionary characteristics, interaction network and cis-acting regulatory elements were predicted and analyzed. Real time-quantitative reverse transcription PCR (RT-qPCR) was used to detect the relative expression level of CsCCD gene family members under different leaf positions and light treatments during processing. A total of 11 CsCCD gene family members, each containing exons ranging from 1 to 11 and introns ranging from 0 to 10, were identified. The average number of amino acids and molecular weight were 519 aa and 57 643.35 Da, respectively. Phylogenetic analysis showed the CsCCD gene family was clustered into 5 major groups (CCD1, CCD4, CCD7, CCD8 and NCED). The CsCCD gene family mainly contained stress response elements, hormone response elements, light response elements and multi-factor response elements, and light response elements was the most abundant (142 elements). Expression analysis showed that the expression levels of CsCCD1 and CsCCD4 in elder leaves were higher than those in younger leaves and stems. With the increase of turning over times, the expression levels of CsCCD1 and CsCCD4 decreased, while supplementary LED light strongly promoted their expression levels in the early stage. The expression level of NCED in younger leaves was higher than that in elder leaves and stems on average, and the expression trend varied in the process of turning over. NCED3 first increased and then decreased, with an expression level 15 times higher than that in fresh leaves. In the late stage of turning over, supplementary LED light significantly promoted its gene expression. In conclusion, CsCCD gene family member expressions were regulated by mechanical force and light. These understandings may help to optimize tea processing techniques and improve tea quality.

OBJECTIVETo transform the antimicrobial peptide fusion gene of cecropin B and rabbit NP-1(CN) into Houttuynia cordata to improve its antimicrobic capability.

METHODThe fusion gene of CN designed and synthesized artificially was recombined with expression vector pBI121. The recombined vector was transformed to Agrobacterium tumefaciens LBA4404, by which CN gene was transformed to the explants of H. cordata. The transgenic regeneration plantlets were selected by kanamycin and rapid screening PCR. The transgenic plants were identified by PCR-Southern of genomic DNA and RT-PCR. The disease resistances were detected by antibacterial zone trail of leaf extracts to E. coli K12 and infection by Rhizoctonia solani.

RESULTGene of interesting CN was inserted into genomic DNA and expressed in transformed H, cordata, whose resistance to E. coli K12 and Rh. solani was stronger than that of the non-transformed control.

CONCLUSIONThe fusion gene CN can improve antimicrobic capability of transformed H. cordata.
