RESUMEN
OBJECTIVE: To understand the effect of evidence-based nursing on diet and pain after subtotal gastrectomy. METHODS: From June 2014 to May 2016, 68 patients with gastric cancer undergoing subtotal gastrectomy were selected as the research group (RG) and 57 patients with routine nursing as the control group (CG). The incidence of complications and recovery time were compared between the two groups. The pain and sleep were evaluated by visual analogue scale (VAS) and Pittsburgh Sleep Quality Index (PSQI). The survival condition of the two groups after 3 years of prognosis was observed. RESULTS: The incidence of complications and recovery time in RG were less than those in CG (P < 0.05), and the VAS and PSQI scores in RG were lower than those in CG on the 3rd and 7th day after operation (P < 0.01). However, the nursing satisfaction and 3-year survival rate of RG were higher than those of CG (P < 0.05). CONCLUSION: Evidence-based nursing can effectively reduce postoperative complications and pain in patients with gastric cancer undergoing subtotal gastrectomy.
RESUMEN
A cotyledon bioassay was conducted to assess the activity of isopyrazam against Podosphaera xanthii (Castagne) U. Braun & N. Shishkoff, causal agent of cucumber powdery mildew. Results showed that isopyrazam has protective and curative activity against P. xanthii, with EC50 values of 0.04 and 0.05 mg liter-1, respectively. These activities are higher than those for hexaconazole, difenoconazole, pyraclostrobin, kresoxim-methyl, and azoxystrobin, fungicides currently used against cucumber powdery mildew. Isopyrazam at 0.5 mg liter-1 damaged conidiophores. Results of inoculation tests in greenhouse pots indicate that isopyrazam demonstrates a level of systemic movement in cucumber plants, especially regarding translaminar and transverse translocation. Efficacy following translaminar and transverse translocations on cotyledons and leaves treated with 60 mg liter-1 was 94.40% and 88.96%, and 95.26% and 82.83%, respectively. In addition, isopyrazam at 60 mg liter-1 exhibited a long duration of efficacy against cucumber powdery mildew, almost 2 to 3 weeks longer than that of triazoles and strobilurins. Similar trends in residual durations were observed during 2014 and 2015 greenhouse trials. Isopyrazam at 30 and 60 a.i. g ha-1 provided efficacy ranging from 83.27 to 90.83% 20 days following treatment. In conclusion, isopyrazam has translaminar and transverse translocation in cucumber leaves, and long duration of activity against cucumber powdery mildew.
