Objective To explore the relationship between the timing of functional training and its therapeutic effects on patients with cerebral infarction. Methods One hundred and fifty-six patients with cerebral infarction of internal carotid artery system were randomly and equally divided into three groups (groups A, B and C), and the functional training was initiated within 7d, 7～30d or over 30d after cerebral infarction in groups A, B, C, respectively. The effects were evaluated at 91d after the functional training. Results Compared with those of group C, the therapeutic effects in groups A and B were significantly better (P

OBJECTIVE: To verify the relationship between THI and VAS scores in patients with sudden hearing loss and tinnitus in a prospective study. METHOD: Forty-four patients classified their tinnitus according to VAS and THI before and after treatment, and both scores were compared through the Pearson's correlation coefficient test and Nonparametric tests. RESULT: There was a correlation between VAS and THI scores in patients with sudden hearing loss and tinnitus. Tinnitus assessment scores were significantly reduced after treatment. Decreasing of THI and VAS scores were not depended on frequency and loudness of tinnitus and severity of deafness, but therapeutic effect of sudden sensorineural hearing loss. CONCLUSION THI and VAS scores are useful for assessment of tinnitus in patients with sudden hearing loss and tinnitus.

OBJECTIVE:To provide reference for the rational clinical prophylactic use of antibiotics. METHODS:The cases in whom the clinical prophylactic use of antibiotics between 2006 and 2007 in our hospital showed failure in efficacy were monitored to analyze the cause of failure,meanwhile the clinical samples were sent for culture,isolation,identification and drug susceptibility tests as well as drug resistance analysis. RESULTS:Cephalosporins,Quinolones,Penicillins,Cefhalosporins + enzyme inhibitor were more commonly used antibiotics in our hospital,with drug resistance rates at 57.21%,65.14%,68.63%,and 18.81% respectively. Among the total 240 cases monitored,the prophylactic use of antibiotics totaled 877 times,of which,388 (44.24%) were non-indicated drug use,459 (52.34%) showed drug resistance,286 (32.61%) involved improper drug choice,and 42 (17.50%) showed dual infection. CONCLUSION:The clinical prophylactic use of antibiotics in our hospital is far from perfect; therefore,it is urgent to tighten control on the standard prophylactic use of antibiotics.

Objective To find out the risk factors of early pulmonary infections after renal transplantatioa Methods The data were collected from 96 patients receiving renal transplantation between Oct. 2006 and Oct 2010, including 48 cases of early lung infection after renal transplantation as infection group, and 48 patients receiving immunosuppressive regimen at the same period as-control group. Taking the factors of lung infecition as variables, t test or chi-square test was used in univariate analyses whereas logistic regression was used in multivariate analyses. Results Single factor analysis showed that induction therapy, albumin levels, dose of steroid in 1 month after operation,family income and prophylactic SMZ treatment were related to lung infectioa Analysis of multiple variables logistic regression revealed that induction therapy, albumin levels, dose of steroid in 1 month after operation and prophylactic SMZ treatment were related to lung infection. Conclusion The correlation analysis indicated that induction therapy and dose of steroid in 1 month after operation have positive correlations with pulmonary infection, while albumin levels and prophylactic SMZ treatment have negative correlations with pulmonary infection.
