The reverse phase nystagmus is not uncommon in clinical practice.Inadequate understanding brings great confusion to clinical diagnosis and treatment,which leads to misdiagnosis frequently and also increases the eco-nomic burden on patients.The purpose of this paper is to summarize and analyze the mechanism,characteristics and clinical significance of reverse phase nystagmus,to help clinicians better understand the significance of inversion nys-tagmus in benign paroxysmal positional vertigo,in order to achieve accurate and efficient diagnosis and treatment of these patients.

Objective To explore the Effects of nursing model on anxiety and sleep of laparoscope cholecystectomy ( LC) patients based on story theory. Methods Totally 50 cases of LC patients were divided into the observation group and the control group according to convenience sampling method, with 25 cases in each group. Patients in the control group received routine nursing care, while patients in the observation group received nursing intervention based on the the story theory. Self-rating Anxiety Scale ( SAS) and Pittsburgh Sleep Quality Index ( PSQI ) were used to evaluate patients′ anxiety and sleep status before and after the intervention. The plasma cortisol concentration of patients in two groups were compared before and after the intervention.Results The SAS score in the observation group after surgery was (33.76±4.62);the PSQI score was (8.28±1.54);the plasma cortisol concentration was (17.35±6.32) ng/mL, and they were all lower than the data in the control group. Repeated measurement anova showed that the differences of SAS score, PSQI score and plasma cortisol concentration in two groups at different time were significant ( Ftime=12.230,16.512,18.041;P<0.05) , and in a downward trend. The nursing effect in the observation group was superior than that in the control group.Conclusions The nursing model based on story theory could significantly improve the anxiety and sleep of LC patients, which was conducive to the rehabilitation of patients after surgery.
