Effects of Evidence-Based Continuing Care Bundle on Health Outcomes in Rectal Cancer Patients With Temporary Stomas: A Multicenter Randomized Controlled Trial.

BACKGROUND: The patients with temporary stomas after anterior resection for rectal cancer may experience significant impact on their health outcomes, and hence continuing care is necessary and important for these patients. However, the effects of some single continuing care interventions remain unclear. Continuing care bundle may be an effective approach to address this uncertainty. OBJECTIVE: The aim of this study was to investigate the effects of an evidence-based continuing care bundle on selected health outcomes in patients with temporary stomas after anterior resection for rectal cancer. METHODS: This was a multicenter randomized controlled trial. A total of 124 patients with temporary stomas after anterior resection for rectal cancer were recruited from 4 general tertiary hospitals in Guangzhou, China, and were randomly assigned to a control group or an intervention group. Both groups received usual care, whereas the intervention group additionally received evidence-based continuing care bundle. Self-efficacy, quality of life, and stoma-related complications were collected at baseline and 4 and 12 weeks after surgery. Satisfaction and outcomes of stoma reversal were collected at the end of the observation. RESULTS: The intervention group had significantly improved the self-efficacy (F = 11.88, P = .001), quality of life (F = 17.99, P < .001) over time, satisfaction (t = 4.08, P < .001), and outcomes of stoma reversal (χ2 = 5.93, P = .015) and reduced the incidence of complications (P < .05). CONCLUSIONS: Evidence-based continuing care bundle can be an effective method to improve the health outcomes among these patients. IMPLICATION FOR PRACTICE: By using the evidence-based continuing care bundle, nurses can help these patients improve their health outcomes in stoma-specific nursing.

[Analysis of differential protein expression of REMI mutant of Trichoderma koningii].

On purpose of expounding the phenotype change of Trichoderma mutant which produces cellulase, protein profiles of T. koningii CICC and its mutant TK-2R-1 were detected by 2-DE. Eight unique spots were found and four of them were identified and their functions by MS-TOF-TOF were connected with growth and metabolization of Trichoderma spp. The research provides a new theoretical basis and methods for the construction of Trichoderma mutant which is used to produce efficient cellulase.

[Cotton laccase gene overexpression in transgenic Populus alba var. pyramidalis and its effects on the lignin biosynthesis in transgenic plants].

Using petioles as explants, a cotton laccase cDNA (GaLA C1) was introduced into Populus alba var. pyramidalis by A. tumefaciens-mediated transformation. PCR and Southern blot analysis indicated that transgene was stably integrated into the genome of transformants. Enzyme assay showed that laccase activity was obviously increased in transformants. As compared with untransformed control, total lignin content in all tested transgenic lines was elevated in varying degrees (as highest as 21.5%). Histochemical staining of lignin further confirmed that overexpressing GaLA C1 could result in increased lignin content in transformants. Together, our data strongly suggested that GaLA C1 may participate in lignin synthesis and this is the first direct transgenic evidence for the involvement of plant laccases in lignification.

[Comparative study on regeneration systems of Cunninghamia lanceolata hook].

Four regeneration systems derived from cotyledon, hypocotyls, stem and needle explants have been established in the comparative researches of regeneration systems in Cunninghamia lanceolata Hook. A high frequency (93.7% +/- 0.45%) of adventitious buds were induced from cotyledons on DCR medium supplemented with 1 mg/L BA and 0.1 mg/L NAA, with a maximum mean number buds of 3.76 +/- 0.25. A higher frequency (96.2% +/- 0.35%) of adventitious buds were induced from hypocotyls on DCR medium supplemented with 2 mg/L BA and 0.2 mg/L NAA, with a maximum mean number buds of 17.4 +/- 0.18. A highest frequency (100%) of adventitious buds were induced from stem segments on DCR medium supplemented with 1 mg/L BA and 0.1 mg/L NAA, with a maximum mean number buds of 3.28 +/- 0.11. A low frequency (84.5% +/- 0.45%) of adventitious buds were induced from needles on DCR medium supplemented with 1.5 mg/L BA and 0.1 mg/L NAA, with a maximum mean number buds of 1.42 +/- 0.08. Buds were elongated on DCR medium supplemented with 0.2 mg/L BA and 0.02 mg/L NAA. After pre-treating shoots, best rooting result was produced on 1/2 DCR medium supplemented with 0.3 mg/L IBA.
