Objective To investigate the responsiveness of the Burke Lateropulsion Scale (BLS) evaluating Pusher syndrome recovery and the characteristics of BLS. Methods 48 patients diagnosed as Pusher syndrome after stroke were included. All the patients were assessed with BLS to measure the progress at admission, every 2 weeks and at discharge, respectively. The characteristics of BLS score at admission and discharge and the standardized response mean (SRM) were analyzed. Results 56.3% patients were rated as mild and 16.7% were rated as severe at admission; none were classified as severe, 43.8% were not enough to be diagnosed as Pusher syndrome and 47.9% were classified as mild on discharge. SRM was 1.27 during the whole hospitalization, and SRM was 1.41 and 2.18 at 4 and 6 weeks, respectively. Conclusion BLS is an appropriate tool for the evaluation of patients with Pusher syndrome and is responsive to monitor the progress and recovery during rehabilitation.

Objective To explore the role of Toll-like receptor 7 (TLR7) and related signal transduction molecules in mechanisms underlying human papilloma virus (HPV) infection and condyloma acuminatum (CA) recurrence.Methods Peripheral blood was obtained from 30 healthy controls,35 patients with primary CA,32 patiens with recurrent CA and 30 patients with recurrent CA treated by imiquimod and ALA-PDT.Two-color flow cytometric analysis was used to detect TLR7 expression in different peripheral blood T cell subsets,Western blot to determine the expression levels of an adapter protein myeloid differentiation primary response gene 88 (MyD88),and signaling molecules including tumor necrosis factor receptor-associated factor (TRAF6),phosphatidylinositol3-kinase (PI3K),protein kinase B (AKT),p42/44 and nuclear factor-kappa B (NF-κB) in peripheral blood CD3+ T cells,from these subjects.Statistical analysis was carried out by Student's t test using the software SPSS 13.0.Results TLR7 was expressed in peripheral blood CD3+CD4+ T cells and CD3+CD8+ T cells from the healthy controls.Compared with the healthy controls,the patients with primary and recurrent CA showed no significant changes in TLR7 expression in CD3+CD8+ T cells,but a statistical increase in TLR7 expression in CD3+CD4+ T cells (23.3% ± 8.4% and 32.8% ± 8.9% vs.12.6% ± 6.3%,t =4.72,10.76,both P < 0.01).Decreased expression of TLR7 in CD3+CD4+ T cells was observed in patients treated with imiquimod and ALAPDT compared with the patients with recurrent CA (20.3% ± 5.7% vs.32.8% ±8.9%,t =5.41,P < 0.01).The protein expressions of MyD88,TRAF6,PI3K,p42/44 and NF-κB were significantly increased in CD3 + T cells,while the AKT protein expression experienced no significant changes in patients with primary or recurrent CA compared with the healthy controls.A significant decrease was observed in the protein expression of MyD88,TRAF6,p42/44 and NF-κB in the treated patients compared with those with recurrent CA.Conclusions TLR7,which is highly expressed in peripheral blood CD3+CD4+ T cells in patients with CA,may take part in the host immune response against HPV and serve as a recognition receptor for HPV infection.

Objective To study the value of MR diffusion tensor imaging (MR-DTI)using a 3.0 T scanner in anterior ischemic optic neuropathy(AION).Methods A total of 26 patients suffering from unilateral subacute AION were examined using DTI and pattern visual evoked potential(P-VEP).The parameters values of optic nerves including fractional anisotropy (FA),ADC,vertical diffusivity (λ⊥),paralleldiffusion (λ//),P100 value and amplitude were obtained.Paired t-tests were used for comparing the FA,ADC,λ⊥,and λ// values of the two groups.Correlations of DTI parameters and P-VEP parameters were analysed by using the Pearson rank correlation analysis.Results The values of FA,ADC,λ//,and λ_ in the affected nerve were 0.28±0.07,(1.43±0.20) ×103 mm2/s,(1.79±0.16) ×10-3 mm2/s,and (1.25±0.17) ×10-3 mm2/s respectively,and the corresponding values of unaffected nerve were 0.57±0.05,(1.04±0.17) ×10-3 mm2/s,(1.71 ±0.19) × 10-3 mm2/s,and (0.75±0.08) × 10-3 mm2/s respectively.Compared to unaffected contralateral nerves,the mean FA was reduced,the mean ADC,λ⊥ were increased in the affected nerves(t=-19.269,10.537,15.301,P<0.01).However,there were no significant difference of the λ//(t=l.632,P>0.05).There was significant negative correlation between ADC and P-VEP amplitude in affected optic nerves (r=-0.722,P<0.01).There was moderate negative correlation between λ⊥ and P-VEP amplitude in affected optic nerves (r=-0.634,P<0.01).There was moderate correlation between FA and P-VEP amplitude (r=0.539,P<0.01).There was no correlation between λ// and P-VEP amplitude.There was moderate negative correlation between FA and P-VEP P100 latency(r =-0.619,P<0.01).Conclusions DTI can sensitively detect diffusional abnormality of anterior ischemic optic neuropathy.DTI could be used as a supplemental way in the assessment of AION.

Objective:To investigate the antimicrobial resistance spectrum of Escherichia coli isolated from different clinical sam-ples to guide the nosocomial infection control and rational use of antibiotics. Methods:Escherichia coli from clinical samples were isola-ted and tested by microbiological assay system of BD Phoenix 100 and susceptibility test card in 2013. The drug resistance was analyzed and compared retrospectively. Results: There were 936 strains of Escherichia coli isolated from our hospital in 2013. Escherichia coli was resistant to common antibiotics at high level. Escherichia coli strains isolated from different samples varied in the drug susceptibili-ty. The resistance rate of the strains from sputum samples was higher than that from the other samples. Conclusion:The status of drug resistance of clinical isolated Escherichia coli to antibiotics is very serious. Escherichia coli isolated from different samples show different drug resistant features, and the antimicrobial therapy should be considered according to the antimicrobial susceptibility tests.

OBJECTIVETo compare the effectiveness of percutaneous microwave ablation ( MWA) versus hepatectomy for multifocal hepatocellular carcinoma.
METHODSFrom August 2002 to March 2012, one hundred and twenty-two patients with multifocal hepatocellular carcinoma (diameters 1 to 7 cm, 2 to 4 lesions) were treated by either complete MWA or radical hepatectomy, and their clinical data were collected and analyzed.The patients were divided into MWA group (n = 50) and resection group (n = 72), and the resection group was matched by MWA group based on clinical parameters. The survival and complications in the two groups were compared.
RESULTSThe overall 1-, 3- and 5-year survival rates were 100.0%, 73.0% and 62.0%, respectively, in the MWA group, and 80.0%, 56.0%, and 41.0%, respectively, in the resection group (P < 0.05). The corresponding recurrence-free survival rates were 88.0%, 63.0%, and 52.0% in the MWA group, and 68.0%, 45.0%, and 36.0%, respectively, in the resection group (P< 0.05). The multivariate Cox regression analysis indicated that albumin level, performance status, treatment modality, and tumor size were independent prognostic factors.
CONCLUSIONCompared with hepatectomy, percutaneous microwave ablation is a minimally invasive and reproducible procedure, and can improve the survival in patients with multifocal hepatocellular carcinoma.

Objective To study the CT findings of pulmonary mucosa-associated lymphoid tissue (MALT) lymphoma. Methods The CT examinations of 12 patients with pathologically proven pulmonary MALT lymphoma were reviewed retrospectively. Evaluated imaging findings included number, distribution,shape, attenuation and other associated findings of each lesion were evaluated. Results Thirty-two pulmonary lesions, including consolidations, masses, nodules and lesions with ground glass attenuation,were identified in 12 patients. Multiple lesions were founded in 10 of 12 patients and solitary lesion in 2 patients. Multiple lesions found in one lung in 2 patients, and multiple lesions found in both lungs in 8 patients. Ten cases demonstrated 21 consolidation lesions with air bronchogram, and one of the ten cases demonstrated two lesions with airway dilatation. Three cases demonstrated 5 masses or nodular lesions, 3 of these 5 lesions showed air bronchogram. Two cases demonstrated 6 ground glass attenuation lesions. One case showed mediastinal and hilar lymphadenopathy. Conclusion Pulmonary MALT lymphoma usually appears as multiple bilateral consolidations, masses, nodules with air bronchogram or lesions with groundglass attenuation at CT imaging. The imaging findings described above and with an indolent clinical course may suggest the diagnosis of pulmonary MALT lymphoma.
