Salt stress reduces the fresh weight, dry weight, and relative growth rate of cucumber (Cucumis sativus) seedlings and results in serious quality loss in cucumber production. Our previous study indicated that the netting-associated peroxidase (CsaNAPOD) protein in cucumber seedling roots was induced by salt stress. Here, we amplified the coding sequence of CsaNAPOD from a cDNA isolated from the roots of cucumber seedlings. Sequence analysis indicated that the coding sequence of CsaNAPOD is 1035 bp, encoding a deduced protein of 344 amino acids, with a predicated molecular weight of 37.2 kD and theoretical isoelectric point of 5.64. The deduced amino acid sequence of CsaNAPOD showed high sequence similarity to peroxidases (PODs) from other plant species. Moreover, CsaNAPOD possesses the typical sequence structures of class III PODs and indicated that CsaNAPOD belongs to this subfamily. CsaNAPOD was highly expressed in the roots and was weakly expressed in the stems and leaves of cucumber seedlings. Salt stress significantly increased the expression of CsaNAPOD in the leaves during the entire experimental period compared with the control, and the expression of CsaNAPOD in roots was reduced at 6 hours and induced at 48 and 72 hours by salt treatment. In stems, the expression of CsaNAPOD declined at 48 and 72 hours as a result of the salt treatment compared with the control. These results indicate that the expression of CsaNAPOD responded to salt stress in cucumber seedlings, and the expression patterns under salt stress in different tissues were not identical. Our research suggests that CsaNAPOD may have potential function during the plant response to salt stress.

We quantitatively assessed the effects of a six-session edible horticultural therapy (EHT) program on long-term-hospitalized (LTH) female patients with schizophrenia. A total of 60 patients were enrolled in the project and randomly divided into an experimental group (30 patients, received EHT) and a control group (30 patients, did not receive EHT). The two groups were evaluated before and after EHT using the Brief Psychiatric Rating Scale (BPRS), the Chinese version Scale of Social Functioning for Psychotic Inpatients (SSFPI), and the Life Satisfaction Index A (LSIA). The clinical symptoms of patients with schizophrenia improved significantly and they recovered social function, but there was no significant change in life satisfaction. In the control group, clinical symptoms recovered but there was no improvement in social function and life satisfaction significantly decreased. In addition, patients in the EHT group expressed satisfaction with the program. In conclusion, EHT can improve the clinical symptoms of schizophrenia and promote recovery of social function; however, its impact on life satisfaction remains unclear.

Extrapyramidal symptoms (EPSs) are common adverse reactions to antipsychotics in patients with schizophrenia. The purpose of this study was to investigate the effects of edible horticultural therapy (EHT) on EPSs in schizophrenic patients. This study assessed the changes in psychopathological symptoms and extrapyramidal symptoms in patients with schizophrenia before and after participating in a six-session EHT. Forty schizophrenic patients, recruited from Wuhan Wudong Hospital, were randomly assigned to the EHT group (average age: 45.40 ± 13.960 years) or the control group (average age: 49.30 ± 12.516 years). The EHT program held weekly sessions from May 2020 to June 2020. A psychiatrist assessed the psychopathological symptoms and extrapyramidal symptoms of schizophrenic patients in both groups with the Chinese version of the Positive and Negative Syndromes Scale (PANSS) and the Rating Scale for Extrapyramidal Side Effects (RSESE). After six courses of horticultural therapy, the terms of positive, negative, and general symptoms on the PANSS significantly improved in the EHT group. Moreover, the EPSs were also significantly improved in the EHT group. However, there was no change in the PANSS and RSESE scores in the control group. This study shows that EHT has the potential to improve not only psychopathological symptoms but also EPSs in psychiatric patients. This adds new evidence for EHT as an adjunct to treatment for schizophrenia.

The present study aims to reveal the karyotypic characteristics and genetic relationships of apricot (Prunus armeniaca L.) accessions from different ecological groups. Fourteen, 9, and 30 accessions from the Central Asian ecological group, North China ecological group, and Dzhungar-Ili ecological group, respectively, were analyzed according to the conventional pressing plate method. The results showed that all the apricot accessions from the different ecological groups were diploid (2n = 2x = 16). The total haploid length of the chromosome set of the selected accessions ranged from 8.11 to 12.75 μm, which was a small chromosome, and no satellite chromosomes were detected. All accessions had different numbers of median-centromere chromosomes or sub-median-centromere chromosomes. The karyotypes of the selected accessions were classified as 1A or 2A. Principal component analysis revealed that the long-arm/short-arm ratio (0.968) and the karyotype symmetry index (−0.979) were the most valuable parameters, and cluster analysis revealed that the accessions from the Central Asian ecological group and Dzhungar-Ili ecological group clustered together. In terms of karyotypic characteristics, the accessions from the Dzhungar-Ili ecological group and Central Asian ecological group were closely related.
