This study deals with colony expansion characteristics, biomass increment and Na accumulation in mycelia of three ectomycorrhizal fungi ( Boletus edulis, Xerocomus chrysenteron and Gomphidius viscidus ) under treatment of Na2SO4 and NaCl. The experimental results showed that no impact was observed from Na2SO4 and NaCl treatments on the growth mode of the mycelia, but the biomass increment of X. chrysenteron and G. viscidus was significantly restrained under 0.1 mol/L Nacl. Under the treatment of Na2SO4, biomass increment of X. chrysenteron is significantly higher than the control, but the biomass of G. viscidus is lower than that of the control, and no significant impact was measured on growth of B. edulis under both treatments of Na2 SO4 and NaCl. The experiment also indicated that Na accumulation in mycelia varied significantly among the three tested strains, highest Na accumulation was measured in X. chrysenteron under treatment of NaCl, while under the treatment of Na2SO4 , accumulation of Na in B. edulis is much higher than the other two strains.

Objective To investigate the effect of all-in-one nursing intervention on esophageal carcinoma patients with bad emotion and immune function. Methods From the October, 2012 to the October, 2013, 102 patients with radical operation of esophageal carcinoma were divided into all-in-one nursing intervention group (research group, 52cases) and routine nursing group (control group, 50 cases) according to the random number table method.Two groups of patients were evaluated before and after operation of anxiety and depression emotion scores, with the Self-rating Anxiety Scale (SAS) and Self-rating Depression Scale (SDS) .At the same time, two groups of patients were detected the stress and immune index before and after the operation. Results Before operation, two groups of patients with anxiety, depression, stress reaction and immune index were not significantly different (P>0.05).After operation, the study group patients with anxiety and depression scores were significantly lower than those in the control group [(34.6+6.7) points vs. (44.8+7.5) points, (33.7+6.9) points vs. (40.6+7.3) points], the difference was statistically significant (t values were 7.234, 4.902, P<0.05). Eighth days after operation, patients in the control group FBG, CRP and Cor levels were significantly higher in the study group [(6.98±1.12)mmol/L vs.(6.09±0.85)mmol/L,(18.11±5.93) mg/L vs.(9.24±3.22)mg/L,(293.98±69.09)nmol/L vs.(221.97±67.94)nmol/L],the difference was statistically significant (t values were 4.532, 9.336, 5.307, P<0.05). Eighth days after operation, two groups of patients with IgA, IgM were higher than first days after operation [(2.41±0.46)g/L vs.(1.89±0.56)g/L,(2.51±0.58) g/L vs.(1.35±0.67)g/L and (2.36±0.53)g/L vs.(1.82±0.46)g/L, (2.34±0.62)g/L vs. (1.37±0.64) g/L], the difference was statistically significant (t values were 5.174, 9.439, 5.549, 7.850, P<0.05).The total number of patients blood lymphocytes (LYM) and cytokines (CD3, CD4, CD8, CD4/CD8) were significantly higher than the control group [(2.87±0.65)×109/L vs.(1.98±0.58)×109/L, 0.62±0.10 vs. 0.57±0.07, 0.41±0.08 vs. 0.35 ±0.08, 0.24 ±0.04 vs. 0.26 ±0.05, 2.06 ±0.44 vs. 1.65 ±0.46], the difference was statistically significant (t values were 7.286, 2.915, 6.942, 2.225, 4.601, P<0.05).
