OBJECTIVE: To study the hearing characteristics in patient with posterior circulation transient ischemic attack (PCTIA). METHOD: Sixty-two patients diagnosed by neurologist were selected as experimental group for testing of pure tone audiometry, tympanometry, otoacoustic emissions (OAE) and auditory brainstem response (ABR). Thirty healthy subjects were chosen as control group. The data were compared between the PCTIA groups and the control group using the SPSS 14.0 software. RESULT: (1) The difference in pure tone threshold across 125 to 8000 Hz between the PCTIA group and the control group was not statistically significant (P>0.05); (2) In PCTIA patients, the prevalence of TEOAE was only 42.7%, significantly different from the control group; (3) The patients had longer ABR latency and wave interval than the normal controls (P<0.01). CONCLUSION Brain-stem and cochlear damage can occur in patients with PCTIA. These results suggest that OAE and ABR be used as important diagnostic test for patients with PCTIA, and might be helpful in localizing abnormality in PCTIA.

Objective To investigate the relationship between heme oxygenase-1 (HO-1),glutathione S-transferase (GST) and cerebral atherosclerosis.Methods Cerebralvascular status was assessed with color flow Doppler sonography,transcranial Doppler (TCD),magnetic resonance angiography (MRA)or/and digital subtraction angiography (DSA) in patients with cerebral atherosclerosis (mild,moderate,and severity).Serum HO-1 and GST were measured with enzyme-linked immunosorbent assay (ELISA).Results In comparison between case and control groups,there was significant difference in age,hypertension,cerebral infarction,uric acid,and HO-1 (P =0.041,0.008,0.000,0.036,and 0.001).The level of serum HO-1 in the severe atherosclerosis was lower than that in the mild and moderate atherosclerosis (P =0.000 and 0.002).Logistic regression was used to find the association of HO-1 and the degree of cerebral atherosclerosis (P =0.000).Conclusions HO-1 might be related to cerebral atherosclerosis.

Objective To design a new type of hybrid bioartificial liver (HBAL), evaluate its efficacy in vitro, and explore the feasibility in clinical application.Methods CL-1 human hepatocytes were cultured on microcarriers for 5 days, when cell count reached about 4.0 × 109 with cell density of about 4.0 × 107/ml.CL-1 cells cultured on microcarriers in home-made bioreactor constitute the biological part of the HBAL.The abiotic part included blood perfusion and bilirubin adsorption, and blood pump was employed as the circulation driver, which were parts of HBAL.The changes of the concentrations of indirect bilirubin (UBD), chenodeoxycholic acid (CDCD), cholic acid (CA), blood ammonia (AA), AST, ALT and LDH were observed under the condition of in vitro circulation.Meanwhile, the function, morphology and the cell activity of CL-1 cells were also observed.Results After in vitro circulation for 24 h, the concentrations of UBD, CDCD, CA and AA significantly decreased from (335.3 ± 6.0) μmol/L, (395.0 ± 5.6) μmol/L, (155.7 ± 4.5) μmol/L, (39.0 ± 2.6) μmol/L at 0 h to (106.0 ± 10.9) μmol/L, (131.8 ± 28.7) μmol/L, (42.2 ± 7.3) μmol/L, (3.5 ± 1.0) μmol/L, respectively.At 48 h, ALT, AST and LDH significantly increased from (25.9 ± 4.2) IU/L, (22.0 ± 3.6) IU/L, (0.28 ± 0.09) μmol/L to (31.0 ± 2.6) IU/L,(31.6 ± 8.0) IU/L, (0.41 ± 0.12) μmol/L, meanwhile the count and vitality of CL-1 cells were significant declined.Conclusions (1) In the new HBAL system, CL-1 cells can keep its viability and function in vitro;and (2) the HBAL appears to be effective in purifying the serum in liver failure simulation model by clearing out non-conjugated bilirubin, chenodeoxycholic acid, cholic acid and ammonium chloride, which seems to be a promising therapeutic option.

Objective To study the clinical application of proportional assisted ventilation (PAV) in the treatment of neonatal respiratory failure.Method From March 2011 to October 2013,a retrospective study was conducted on newborns receiving ventilation therapy for respiratory failure.The newborns were assigned into PAV group and synchronized intermittent mandatory ventilation (SIMV) group.Arterial blood pH 、partial pressure of arterial oxygen (PaO2)、partial pressure of arterial carbon dioxide (PaCO2) and oxygenation index (OI) were compared at the time before ventilation and 2 h,6 h,12 h,24 h after ventilation.The frequency of sedative usage and average time of ventilation between the two groups were compared.Result A total of 30 cases were enrolled in the PAV group and the SIMV group respectively.Before ventilation,no statically significant differences existed on blood pH[(7.13 ± 0.12)、(7.14 ±0.11)],PaO2[(41.1 ±8.9),(40.8±8.8) mmHg],PaCO2[(76.4±12.6),(73.2±13.5) mmHg]and OI between the two groups (P ＞ 0.05).2 h after ventilation,the blood pH [(7.25 ± 0.17)、(7.23 ± 0.15)],PaO2 [(51.0 ± 5.6)、(48.6 ± 5.3) mmHg] and OI were significantly improved,while PaCO2 [(66.3 ± 8.7)、(64.0 ± 7.5) mmHg] decreased.Comparing with data before ventilation,those parameters were statistically improved at each time point after ventilation (P ＜ 0.01).But no statistically differences existed between the two groups at the same time (P ＞ 0.05).Sedatives were used (2.3 ± 1.2)times/case in PAV group and (3.9 ± 2.2) in SIMV group,with statistically differences between the two groups (P ＜ 0.05).Average duration of ventilation were (5.1 ± 1.9) d in PAV group and (5.4 ± 2.1) d in SIMV group,with no statistically differences between the two groups (P ＞ 0.05).Conclusion PAV is very effective in treating the neonatal respiratory failure and worth spreading.
