Alzheimer' s disease (AD) is the most common form of dementia in the elderly. AD is an invariably fatal neurodegenerative disorder with no effective treatment. Senescence-accelerated mouse prone 8 (SAMP8) is a model for studying age-related cognitive impairments and also is a good model to study brain aging and one of mouse model of AD. The technique of cDNA microarray can monitor the expression levels of thousands of genes simultaneously and can be used to study AD with the character of multi-mechanism, multi-targets and multi-pathway. In order to disclose the mechanism of AD and find the drug targets of AD, cDNA microarray containing 3136 cDNAs amplified from the suppression subtracted cDNA library of hippocampus of SAMP8 and SAMR1 was prepared with 16 blocks and 14 x 14 pins, the housekeeping gene beta-actin and G3PDH as inner conference. The background of this microarray was low and unanimous, and dots divided evenly. The conditions of hybridization and washing were optimized during the hybridization of probe and target molecule. After the data of hybridization analysis, the differential expressed cDNAs were sequenced and analyzed by the bioinformatics, and some of genes were quantified by the real time RT-PCR and the reliability of this cDNA microarray were validated. This cDNA microarray may be the good means to select the differential expressed genes and disclose the molecular mechanism of SAMP8's brain aging and AD.

METHODSFrom January 2011 to October 2013, 90 patients with cervicogenic sudden hearing loss were randomly divided into treatment group and control group according to the random number table produced by SPSS 19.0 software. In the treatment group, there were 17 males and 28 females, aged from 31 to 62 years old with an average of (47.57±9.43) years; course of disease was from 1 to 3 days with an average of (1.43±0.68) days; pure-tone audiometry score was from 46.5 to 77.8 dB with the mean of (61.20±9.83) dB; Northwick Park Neck Pain Questionnaire (NPQ) score was from 17 to 31 scores with an average of (23.46±7.18) scores. In the control group, there were 15 males and 30 females, aged from 28 to 64 years old with an average of (45.77±6.99) years; course of disease was from 1 to 3 days with an average of (1.50±0.73) days; pure-tone audiometry score was from 48.1 to 75.0 dB with the mean of (63.91±8.05) dB; Northwick Park Neck Pain Questionnaire (NPQ) score was from 20 to 29 scores with an average of (25.61±10.43) scores. The patients of control group were treated with dexamethasone intravenous drip of 10 mg, 3 days later, decreased to 5 mg, 3 days again. And with the methycobal intravenous drip of 500 μg, treatment continued for 10 days. The patients of treatment group were treated with chiropractic additionally except for the therapeutic methods of control group. Chiropractic included local muscle loosening, attacking point, bilateral pulling atlanto-axial joint, and continuous treatment for 10 days. The pure-tone audiometry score and NPQ score were compared between two groups after treatment.

RESULTSAfter the treatment, pure-tone audiometry score and NPQ score in treatment group improved to (40.23± 8.14) dB and (12.70±8.29) scores respectively, which were obviously better than that of control group's (37.70±10.61) dB and (21.24±11.13) scores (P<0.05).

Objective To evaluate the usefulness of serum galactemannan(GM) for the diagnosis of invasive pulmonary aspergillosis (IPA) in critically ill patients. Methods Study was conducted between February 2007 and July 2008. Included patients on admission ICU who suffer from suspected IPA. GM test and culture were collected 2 weekly. Chnical feature, mycological evidence and optical density index (ODI) were noted. Clinically invasive fungal infection(IFI) were defined proven, probable and possible. The patients were classified into neutropenia, non-neutropenia and treated with immunosuppressive agents, non-neutropenia and non-immunosuppressive agents. To compared of the sensitivity and specificity of GM in different patients. Results 94 patients were included, 4 patients were proven, 29 patients were probable, 34 patients were possible IFI, 27 patients were non-IPA. The positive rate of the GM was 31.9% (30/94). The sensitivity and specificity of GM in proven cases and probable cases are 66.7% and 92.6%. GM assay tended to become positive earlier than the culture 2-10(5.33±2.17)d. We found that differences in patient diagnosis and selection might account for the disparities seen for positive rate for the GM test. There was positive in three of the four patients with proven, the positive rate of GM was 65.5% for probable cases, for possible cases was 17.6%, for non-IPA cases was 7.4% (P=0.001). For patient with neutropenia , treated with immunosuppressive agents and without immunosuppressive agents, the positive rate of GM was 52.9%vs 41.7% vs 34. 6% (P=0.015) ;the sensitivity was 80.0% vs 70. 0% vs 53.8% (P=0.011), the ODI was 1.365 (0.582-6.736) vs 1. 123 (0. 623-6.868) vs 0.554 (0.522-0.823), P=0. 005, respectively. Conclusion These results show that GM test is useful for early diagnosis IPA in critically ill patients. Differences in patient selection and diagnosis might account for the disparities seen for positive rate and sensitivity for the GM test. It has been higher sensitivity and ODI in the patient treated by immunosuppressive agents.

Objective To identify the genotypos of extended spectrum β-1actamase (ESBLs)-producing of Escherichia coli ( E. coli) clinical strains isolated from the Macao and compare the results with the genotypes of clinical strains collected in the first Clinical College, China Medical University (CMU) in Shengyang. Methods The clinically isolated E. coli strains including 209 strains from Macao and 150 strains from CMU were collected. Based on the standard of CLSI2006, the ESBLs-producing strains was identified and its isoelectric point(pI) value was detected by isoelectric focusing (IEF) method. The pI values were used to design the primers for PCR amplification. The amplified DNA sequences were then compared with the GenBank and the ESBL genotypes were confirmed. Results ( 1 ) The positive rate of ESBLs-producing strains of E. coli was 30. 1% (62/209) from Macao and 54. 0% (81/150)from CMU.
