ABSTRACT
To investigate the changes of vedionystamography(VNG)in patients with posterior circulation ischemia vertigo(PCIV).Fifty patients who complained of vertigo and imbalance with PCI were selected as experimental group for testing of visual nystamography(VNG).Thirty normal subjects were chosen as control group.The result was analyzed.The results of VNG in PCIV group and the control group were compared.The abnormal ratio were as follows:(4%,0;>0.05)for Spontaneous nystagmus,(68%,10%;<0.01)for Saccade Test,(42.0%,6.7%;<0.01)for Tracking Test,(44%,0;<0.01)for Optokinetic Test,(78%,10%;<0.01)for Positional Test,respectively.The intensity of positional nystagmus in those patients was(4.12±3.46)°/s,which was much higher than that of the control group(<0.01).One or more abnormal findings for visual-oculomotor system examination were shown in 37 patients(74%).Both vestibular central and peripheral system can be involved in PCIV.VNG test has clinical significance in differential diagnosis and lesion location.The abnormal ratio of visual nystamography in PCIV group reaches 92%(46/50).These results suggest that VNG be used as an important accessory diagnostic tool for patients with PCIV.

Objective To observe the clinical effect of Danshen Chuangxiongqin Injection in treatment of posterior circulation ischemia vertigo.Methods Patients (80 cases) with posterior circulation ischemia vertigo attack in Anhui Hospital of Traditional Chinese from March 2015 to March 2017 were randomly divided into control and treatment groups,and each group had 40 cases.Patients in control group were treated by Betahistine mesylate,6 mg/time (3 times/d) for 2 weeks.Patients in treatment group were iv administered with Danshen Chuangxiongqin Injection (10 mL/d) added into normal saline 250 mL,once daily for 2 weeks.After treatment,the efficacy was evaluated,and the levels of blood viscosity index,fibrinogen in two groups before and after treatment were compared.Results Total effective rate of observation group was 92.5％ which was higher than the control group's 72.5％ with significant difference (P ＜ 0.05).After treatment,the laboratory indexes (levels of blood viscosity,fibrinogen,and so on) were decreased,the improvement degree of these indexes in treatment group were significantly better than those in control group,with significant difference between two groups (P ＜ 0.05).Conclusion Danshen Chuangxiongqin Injection has significant effect in treating posterior circulation ischemia vertigo and it is worthy of clinical application and promotion.
