Clinical research on postoperative efficacy and related factors of early simulation hyperbaric oxygen therapy for severe craniocerebral injury.

In order to discuss the clinical efficacy of simulation hyperbaric oxygen therapy (HBOT) for severe craniocerebral injury and analyze the related factors of it, 108 patients who transferred to our department during December 2010 - December 2014 for ventilator treatment after operation of severe craniocerebral injury were taken as the subjects of the study. These patients were divided into conventional treatment group and simulation hyperbaric oxygen therapy group to contrast the curative effects. At the meantime, GOS score and length of stay in intensive care unit (ICU) of two groups 6 months after treatment, as well as changes in the indexes of the HBO group during treatment were performed statistical analysis.

[Effects of different NO3- concentrations on the growth and antioxidant enzyme systems of strawberry seedlings].

The effects of different NO3- concentrations (CK, 16 mmol x L(-1) NO3-; T1, 48 mmol x L(-1) NO3-; T2, 96 mmol x L(-1) NO3-; T3, 144 mmol x L(-1) NO3-) on the growth properties and antioxidant enzymes activities of strawberry seedlings were studied by sand culture. The results indicated that the plant height, leaf area, dry matter accumulation and root/shoot ratio of strawberry seedlings in T1, T2 and T3 were significantly decreased compared to the control (CK) after 15 days of treatment. The plant heights in T1, T2 and T3 decreased by 16.
