Objective:To analyze the abnormal vestibular function of Wernicke encephalopathy (WE) and to explore its diagnostic value.Methods:WE patients who visited the Vertigo Center of the Second Affiliated Hospital of Zhengzhou University from January 2018 to January 2021 were retrospectively collected. All patients were evaluated by clinical neurology. Before treatment, all patients completed video head impulse test (vHIT) and video nystagmusgraphy (VNG) in addition to cranial magnetic resonance and serum thiamine level examination.Results:All 12 patients had a history of eating defects, including 8 cases of alcoholism. All 12 patients had walking instability, 7 cases had dizziness and 8 cases had oscillopsia. Six cases had ophthalmoplegia. All 12 cases showed positive gaze nystagmus. The pathological saccades of bilateral horizontal semicircular canals were found in 12 patients by vHIT before treatment, but there was only 1 patient showing abnormality in vertical semicircular canals, the difference being statistically significant ( P<0.05). All patients could detect bilateral, horizontal, gaze-evoked nystagmus, including 3 cases with vertical nystagmus, 1 case with abnormal saccade test, 3 cases with abnormal smooth tracking test and 1 case with abnormal optokinetic test. There were abnormalities in the caloric test, including 6 cases of bilateral dysfunction and 2 cases of unilateral dysfunction. Conclusions:WE patients may have abnormal vHIT and bilateral, horizontal, gaze-evoked nystagmus, which is similar to the special abnormal signs of simultaneous damage of both peripheral and central vestibular dysfunction.Vestibular function test is valuable for diagnosis of WE, and it is suitable for patients with a history of nutritional disorders who have dizziness or walking instability and suspected WE.

Objective To investigate the effect of urinary kallidinogenase on serum concentrations of hydrogen sulfide (H2S),neuron-specific enolase (NSE),and S100β in patients with cerebral infarction (CI).Methods From June 2011 to June 2014,80 patients with CI were chosen as study objectives.All patients were divided into two groups:40 patients in study group (urinary kallidinogenase group),and 40 patients in control group.The death rate,the rate of complication and National Institute of Health Stroke Scale (NIHSS) were compared between two groups.The concentrations of H2S,NSE,and S100βwas compared between two groups.Results In study group,the death rate was 5.00% (2/40),the rate of complication was 22.50% (9/40);in control group,the death rate was 12.50% (5/40),the rate of complication was 15.00% (6/40);and no significant significance was found between two groups (P > 0.05).The NIHSS was (11.2 ± 3.2) in the study group,and (15.7 ± 2.7) in the control group,with statistically significant difference between two groups (P < 0.05).After treatment,the concentrations of H2 S,NSE,and S100β of two groups were decreased significantly (P <0.05).At 1w,2w,and 3w,the concentrations of H2S,NSE and S100βhad statistically significant difference between two groups (P < 0.05).Conclusions Urinary kallidinogenase has a cerebral protective effect,which can decrease the concentration of H2S,and increase the concentrations of NSE and S100βin CI patients.
