ABSTRACT

Peanut yield and quality are seriously affected by pod rot pathogens worldwide, especially in China in recent years. The goals of this study are to analyze the structure of fungal communities of peanut pod rot in soil in three peanut cultivars and the correlation of pod rot with environmental variables using 454 pyrosequencing. A total of 46,723 internal transcribed spacer high-quality sequences were obtained and grouped into 1,706 operational taxonomic units at the 97% similarity cut-off level. The coverage, rank abundance, and the Chao 1 and Shannon diversity indices of the operational taxonomic units were analyzed. Members of the phylum Ascomycota were dominant, such as Fusarium, Chaetomium, Alternaria, and Sordariomycetes, followed by Basidiomycota. The results of the heatmap and redundancy analysis revealed significant variation in the composition of the fungal community among the three cultivar samples. The environmental conditions in different peanut cultivars may also influence on the structure of the fungal community. The results of this study suggest that the causal agent of peanut pod rot may be more complex, and cultivars and environmental conditions are both important contributors to the community structure of peanut pod rot fungi.

ABSTRACT

Objective To analyze computed tomography imaging features of primary adrenal schwannoma.Methods The clinical and radiological data of six cases of adrenal schwannoma confirmed by histopathology were analyzed in this study.Results All six cases of adrenal schwannoma were well-circumscribed,round-like or oval-like,solid and cystic tumors,in which two cases were with calcification,and three cases with septations.On the enhanced CT images,all six tumors displayed progressive enhancement.Conclusion Adrenal schwannoma usually presents a well-defined heterogeneous mass with cystic degeneration,sepations,calcification and characteristic progressive contrast enhancement.

ABSTRACT

Objective To analyze the different spreading patterns and the prognostic factors of nasopharyngeal adenocarcinoma (NPAC).Methods The clinical and radiological data of 39 pathologically confirmed consecutive cases of NPAC were retrospectively reviewed.Results In the 1 1 patients with CT/MRI-detected cranial nerve (CN)involvement,there were ACC (n=7),CAC (n=2)and MEC (n=2)(P <0.05).Lymph node metastasis occurred in 40% of CAC,7.7% of ACC and 1 6.7% of MEC (P =0.035). Significant differences were observed in 5 year OS and DFS rates between patients with and without CT/MRI-detected CN involve-ment (P <0.001;P =0.001).In 1 9 patients with early stage disease (stageⅠ-Ⅱ),significant difference was observed in 5 year OS rate between the surgical treatment group and non-surgical treatment group (P =0.038),and the difference was not significant in DFS (P =0.056).Conclusion CT and MRI are valuable tools not only for discovering the different spreading patterns of NPAC, but also for its prognosis.

ABSTRACT

Objective To investigate the effect of curosurf in treatment of children with hyaline membrane disease and the nursing. Methods 56 cases of children patients with hyaline membrane disease from June 2008 to June 2010 admitted to neonatal wards were selected. The control group (26 cases)treated with mechanical ventilation alone and corresponding conventional care, on this basis, the treatment group (30 cases) was treated with curosurf and give systemic nursing intervention. Symptomatic relief time, mechanical ventilation time, length of stay, complication incidence rate, death rate, PaO2 and PaCO2 before and after treatment were observed in two groups. Results Symptomatic relief time, mechanical ventilation time, length of stay, complication incidence rate in the treatment group was significantly lower than that in the control group; PaO2 and PaCO2 amelioration in the treatment group was better than the control group. Conclusions Children with hyaline membrane disease should be treated with curosurf and given systemic nursing intervention as early as possible, it can rapidly improve the symptoms of hypoxia, reduce complications, decrease mortality, accelerate the recovery of disease.
