Effect of hyperbaric oxygen therapy on BI index, GCS, SAS and SDS in patients with craniocerebral injury

Objective: To research and analyze the effect of psychological nursing intervention on self-rating depression (SDS), self-rating anxiety scale (SAS), Glasgow Score (GCS), Barthel index (Barthel, index, BI) of patients. Methods: From September 2015 to September 2016, 84 patients with craniocerebral injury admitted to our hospital were divided into observation group (n = 42) and control group (n = 42) according to randomized single blindness method. All patients were treated with hyperbaric oxygen therapy. The control group was given routine nursing care, while the observation group was treated by psychological nursing intervention. Results: The scores of GCS in the observation group after 2 weeks and 8 weeks of treatment were respectively (7.79±1.42), (11.86±2.56) which were higher than those in the control group (6.23±1.01), (8.21±1.65) the data show significant difference. After treatment, the scores of SDS and SAS in the observation group were respectively (39.14±1.21), (41.67±1.12) which were lower than those in the control group (45.56±2.50), (56.89±2.47) the data show significant difference. The BI index of the observation group was (43.29±4.63), which was higher than that of the control group (36.83±3.10), the scores of NFD was (23.12±1.01) in the observation group, which was lower than that in the control group (28.45±1.67), the data were statistically significant. Conclusion: Psychological care intervention in patients with craniocerebral injury treated by hyperbaric oxygen therapy is helpful to improve the adverse psychological state and consciousness state, improve the ability of daily living activities and promote the recovery of neurological function. It can be actively promoted and applied in clinical practice.

Negative Phase Time Effectin Potential-Well Passing

The properties of phase time taken for particles to pass through a quantum potential well are investigated. It is found in a 1 dimensional quantum mechanical problem that the phase time is negative when the incident energy and the thickness of potential well satisfy certain conditions. Similar results are also found in a 2 dimensional fully relativistic optical analog. It is shown that the expression of the la teral shift of transmitted optical waves is similar to that of the phase time in the 1 dimensional quantum mechanical problem. The phase time in the 2 dimensional optical problem is also shown to be negative under certain conditions.

Effect of hyperbaric oxygen therapy on SAS and SDS in children with ischemic encephalopathy

Objective: To study and analyze the effect of early psychological intervention on the scores of SAS and SDS in children with hypoxic-ischemic encephalopathy undergoing hyperbaric oxygen therapy. Methods: A total of 64 children with hypoxic - ischemic encephalopathy enrolled in our hospital from July 2015 to July 2016 and their parents were selected as study subjects. The patients were treated with hyperbaric oxygen therapy, while their parents were given early psychological intervention. By the way of increasing parents' awareness of the disease, helping parents build confidence in their children's treatment and encouraging them to participate in daily training for their children to relieve their anxiety and depression. The parents' knowledge of the disease before and during treatment, the treatment of hyperbaric oxygen therapy and the change of SAS and SDS were observed. Results: After effective intervention, the scores of SAS and SDS of 64 patients' parents were significantly lower than those before treatment. After 1 courses of intervention, the score of SAS was (43.36 ± 1.27) points, and the score of SDS was (45.22 ± 8.13) points. After 2 courses of intervention, the score of SAS was (41.07 ± 1.21) and the score of SDS was (42.35 ± 7.44) points, and parents' awareness of hypoxic-ischemic encephalopathy was significantly increased, and the differences between the two groups were statistically significant. Conclusion: Early psychological intervention on parents of children with hypoxic-ischemic encephalopathy can effectively improve the awareness of parents on the disease, so as to improve their acceptance of hyperbaric oxygen therapy;significantly reduce the parents' SAS, SDS score. It is beneficial to build a good doctor-patient and nurse-patient relationship, improve the treatment effect and shorten the treatment time.

On the Strong n-partite Tournaments with Exactly Two Cycles of Length n-1

Gutin and Rafiey（Australas J. Combin. 34（2006）, 17-21） provided an example of an n-partite tournament with exactly n-m ＋ 1 cycles of length of m for any given m with 4 ≤ m ≤ n, and posed the following question. Let 3 ≤ m ≤n and n ≥ 4. Are there strong n-partite tournaments, which are not themselves tournaments, with exactly n-m ＋ 1 cycles of length m for two values of m？ In the same paper,they showed that this question has a negative answer for two values n-1 and n. In this paper, we prove that a strong n-partite tournament with exactly two cycles of length n-1 must contain some given multipartite tournament as subdigraph. As a corollary, we also show that the above question has a negative answer for two values n-1 and any l with 3 ≤ l ≤ n and l ≠n-1.
