Articles about vertebral artery injuries secondary to blunt cervical spine trauma are increasing recently. The incidence of the disorder is reported from 19.4% to 46% in the literature. It has been found that unilate ral facet dislocations and bone fragments in the foraminal canal (comminuted fr acture of the foramen transversarium) have a significant association with the vertebral artery injuries,and that rotational violence may be a significant fac tor in causing vertebral artery occlusion. Patients with vertebral artery injuri es may have such symptoms as blurry vision, syncope, dysphagia and Wallenbergs syndrome. MRA(magnetic resonance angiography) is noninvasive and easy to per form at the time of initial MR. A routine evaluation of the extracranial circula tion with MRA should be performed as an additional sequence to all initial MR of the cervical spinal cord injury. Conventional angiography may be indicated only if the patient develops symptoms of cerebral ischemia. The benefit of antithrom botic therapy in reducing neurological morbidity and improving outcome has not y et been established and needs long-term follow-up. Operative management should be reserved only for patients with severe active bleeding or when interventiona l radiology fails. The surgical exposure is complex and demands excellent knowle dge of the local anatomy.

Objective To explore the therapeutic effect of drug combined with psychological intervention on the patients with chronic urticaria.Methods 119 patients who were diagnosed and diagnosed in our hospital from October 2015 to November 2016 were randomly divided into experimental group and control group according to the time of hospitalization.example.The experimental group for drug and psychological intervention in the double treatment;the control group for simple drug treatment.Results There were different degrees of mental health problems in patients with chronic urticaria, and there were many significant differences in mental health problems, such as tension, insomnia, anxiety and mood, muscle system symptoms.In the experimental group and the control group, there was no significant difference between the experimental group and the control group.However, the data of the experimental group and the control group were statistically significant (P<0.05), but there was no significant difference between the experimental group and the control group.In addition, after 4 weeks of treatment, the experimental group and the control group of patients with significant differences in treatment, respectively, 91.53% and 79.66%.There was significant difference between the two groups (P<0.05).Conclusion Compared with the single drug treatment, the effect is more significant which drug combined with psychological intervention was used on the treatment of the patients with chronic urticaria, and has certain positive significance.It can be popularized in clinical practice according to the actual situation.
