Affine vector fields on Finsle manifolds

We give characterizations of affine transformations and affine vector fields in terms of the spray. By utilizing the Jacobi type equation that characterizes affine vector fields, we prove some rigidity theorems of affine vector fields on compact or forward complete non-compact Finsler manifolds with non-positive total Ricci curvature.Comment: 9 page

Efficacy of co-administration of oxiracetam and butylphthalide in the treatment of elderly patients with hypertensive intracerebral hemorrhage, and its effect on NIHSS and ADL scores

Purpose: To investigate the effect of combined use of oxiracetam and butylphthalide on hypertensive intracerebral hemorrhage (HICH) in elderly patients, and its influence on NIHSS and activities of daily living (ADL) scores of patients.Methods: Ninety (90) elderly patients with HICH who were admitted to Renmin Hospital of Wuhan University, Wuhan, China served as study subjects, and were randomly assigned to control and study groups, with 45 patients per group. The patients in the control group were treated with oxiracetam alone, while patients in the study group received a combination of oxiracetam and butylphthalide. Clinical efficacy, undesirable side effects and serum indices were determined. The NIHSS and ADL rating scales were used to evaluate cerebral nerve function and ADL score before and after treatment.Results: There were significantly higher total treatment effectiveness and lower incidence of adverse reactions in the study group than in control group, while tissue inhibitor of metalloproteinase-1 (TIMP-1) index, matrix metalloproteinase-9 (MMP-9) index and NIHSS score were reduced in study patients, relative to controls (p < 0.001). However, ADL score in the study group was higher than that in the control group (p < 0.001).Conclusion: Treatment of elderly patients with HICH using a combination of oxiracetam and butylphthalide improves various serum indices, cerebral nerve function and ADL, as well as clinical efficacy. Further research on the combined medication will help to establish a reliable treatment plan for these patients

EFFECTS OF HEALTH EDUCATION BASED ON OMAHA SYSTEM ON ANXIETY, DEPRESSION AND SELF-MANAGEMENT ABILITY OF PRIMIPARA

Background: Primiparas are prone to tension, anxiety, depression and other emotions due to their lack of experience related to delivery and fear of the unknown during pregnancy. Meanwhile, their self-management ability decreases because of their failure to immediately adapt to the transformation of their roles in a short time. A nursing model was constructed in this study based on the combination of the Omaha System with PBL health education to examine the effect of this model on the anxiety, depression, quality of life and self-management ability of primiparas. Subjects and methods: From January to December 2020, 170 primiparas were recruited as volunteers in this study by means of voluntary registration. They were randomly divided into the observation group and the control group, with 85 members in each group. The intervention lasted 6 weeks. SDS, SAS, WHOQOL-BREF scale and ESCA scale were used to compare the scores of the two groups before and after the intervention. Results: (1) After the intervention, the changes of the observation group in self-management ability and its four dimensions are higher than those of the control group, with the differences being statistically significant (P<0.05). (2) After the intervention, the changes of the observation group in quality of life and its four dimensions are higher than those of the control group, with the differences being statistically significant (P<0.05). (3) The changes of the observation group in anxiety and depression are higher than those of the control group. Specifically, the change of the observation group in anxiety before and after the intervention is 6.40+5.61, in comparison with 2.67+3.71 in the control group; the change of the observation group in depression before and after the intervention is 9.07+8.42 in comparison with 3.19+7.06 in the control group. Conclusion: the new nursing method proposed in this study effectively improves the self-management ability and quality of life of primiparas, significantly reduces their anxiety and depression, has a high application value in obstetric nursing and also provides a new idea for the implementation of scientific and efficient nursing for primiparas
