AIM: To observe the synergetic analgesic effects of low dose of haloperidol, a dopamine antagonist and under-threshold dose of morphine on mice induced by thermal and acetic acid, and to analyze the major mechanism of their synergetic actions. METHODS: To examine the analgesic synergetic effect of haloperidol (0.315 mg/kg, 0.625 mg/kg, 1.25 mg/kg, ip respectively), morphine (3.125 mg/kg, 6.25 mg/kg, 12.5 mg/kg ip, respectively) or combining effect of haloperidol (0.3125 mg/kg) with morphine (3.125 mg/kg) on mice, we compared the change of pain threshold stimulated by thermal, latent period of twisting, the number of times of twisting by acetic acid, and we also estimated the antagonistic effect of d -amphetamine (10 mg/kg) and naloxone (5 mg/kg) on haloperidol and morphine group. RESULTS: Combination of haloperidol with morphine significantly enhanced pain threshold of mice induced by thermal, prolonged latent period of twisting and decreased the number of times of twisting. Naloxone markedly antagonized the combination of analgesic action of haloperidol and morphine and not d -amphetamine. CONCLUSION: Combination of haloperidol with morphine have synergetic analgesic effect and morphine is the dominant factor.

OBJECTIVE To explore occurrence, distribution,and resistance profile of ?-lactamases in clinical isolates of Enterobacter cloacae for rational use of antibiotics in clinic. METHODS Susceptibility test to 13 antibiotics was also performed through disk diffusion test.ESBLs were conformed according to NCCLS.DIDST test was adopted to detect AmpC ?-lactamases in E.cloacae isolates. RESULTS Among 78 isolates collected,13(14.9%) produced AmpC ?-lactamases,24(27.6%) produced ESBLs,10(11.5%) produced both ?-lactamases.These produced(?-lactamases) strains resisted to almost all ?-lactams,except for imipenem.The ?-lactamases producers possessed seriously multi-and cross-drug resistance. CONCLUSIONS ESBLs and AmpC ?-lactams are the main mechanism of E.cloacae resistance to antibiotic.

Objective To explore the change of serum sIL-2R and IL-6 levels in patients with Kawasaki disease (KD) and its role in the pathogenesis. Methods The serum slL-2R and IL-6 were detected by sandwich ELISA. The serum hs-CRP level was measured by DADE BEHRING BN ProSpec. Results The serum levels of sIL-2R and hs-CRP in KD before and after high-dose intravenous gama globulin(IVIg) were significantly higher than in healthy controls (P

Estrogen receptor alpha (ERalpha) has been a primary target of treatment as well as a prognostic indicator for breast cancer. The level of human X-box binding protein 1 (XBP-1) mRNA was related with that of ERalpha in breast tumors and was over-expressed in some breast tumors. These previous studies suggested that XBP-1 may interact with ERalpha. XBP-1 has two isoforms, XBP-1S and XBP-1U, as the result of unique splicing. GST pull-down assay showed that both XBP-1S and XBP-1U bound to ERalpha in vitro. The binding of XBP-1S to ERalpha was stronger than that of XBP-1U to ERalpha. Co-immunoprecipitation revealed that the binding was in a ligand-independent manner. XBP-1S and XBP-1U interacted with the region of ERalpha that contains a DNA-binding domain. The ERalpha-interacting regions on XBP-1S and XBP-1U have been mapped to two regions, the N-terminal basic region leucine zipper domain (bzip) and the C-terminal activation domain. These findings suggest that XBP-1S and XBP-1U may participate in ERalpha signaling pathway through the mediation of ERalpha.

OBJECTIVETo investigate the association between cervical curvature and cervical sympathetic symptoms.

METHODSThe clinical data of 318 patients with cervical spondylosis who underwent surgical treatment in our department between July 2003 and December 2007 were retrospectively analyzed. All patients were divided into group without sympathetic symptoms (n = 284) and group with sympathetic symptoms (n = 34) . The curvatures of both groups on cervical lateral radiographs were measured using Borden method and statistical analysis was performed.

RESULTSThe incidence of abnormal cervical curvature in group with cervical sympathetic symptoms were 67.6% (23/34), which was significantly higher than that in group without cervical sympathetic symptoms (50.7%, 144/284) (P < 0.05).

CONCLUSIONCervical curvature abnormality may be an independent factor that affects the cervical sympathetic symptoms.

AIM:To evaluate the recovery about the visual cortex function of stereopsis in anisometropic amblyopia after regular amblyopia treatment 6, 12 and 18mo with blood oxygenation level dependent - function magnetic resonance imaging techniques ( BOLD-fMRI) .
METHODS: In this study, self-controlled study before and after treatment was used, and blocks-designed fMRI was performed on 11 children which was the first phase of research for amblyopic treatment. Functional MRI data were processed by using SPM8 which based on the Matlab 7. 12. 0. 635. Through the hypothesis drive method, the differences range of activated area in each group were compared by before and after amblyopia treatment matched t-test.
RESULTS: The functional area that was left occipital lobe (BA18), middle occipital gyrus (BA19), limbic lobe (BA19), lingualis gyrus of the right occipital lobe (BA17) and the bilateral parietal lobe ( BA7 ) expanded after amblyopia treatment 6, 12mo, compared those treatment phase, mean t value was 1. 5762, 1. 6856 respectively (P<0. 001). However, the difference of activated intensity was lower after 18mo, mean t value was 1. 1473 (0. 001 CONCLUSION: In children anisometropic amblyopia, the speed of function reconstruction about visual cortical functional mediating stereopsis increase slowly after amblyopia treatment 1a.

AlM: To examine the retinal nerve fiber layer ( RNFL ) changes in early primary open angle glaucoma ( POAG ) by comparing the superior half of the optic disc with the inferior disc half.METHODS: lt was a clinical observational study. The study included 30 patients ( 39 eyes ) with POAG and 20 normal subjects ( 40 eyes ) . Visual field was tested by Zeiss Humphrey750 and the optic disc topographic parameters and RNFL thickness were measured by Zeiss Cirru HD-OCT. Collecting information included visual field mean defect ( MD ) , glaucoma hemifield test ( GHT ) , intraocular pressure ( lOP ) , C/D ratio and RNFL thickness. Data were analyzed by statistic software SPSS18. 0. The differences between two groups were assessed using t test.RESULTS: The differences of superior RNFL minus inferior RNFL thichness on the corresponding clock-hour locations were caculated in two groups. There was a significant difference in superonasal- inferonasal RNFL thickness between two groups (t=2. 526, P=0. 014), and there were no significant differences in the others ( all P>0. 05).CONCLUSlON: The asymmetry of optic disc hemifield RNFL is found in early primary open angle glaucoma patients. The superonasal RNFL ( 1 o’clock for right eye, and 11 o’clock for left eye ) is more fragile to loss than inferonasal RNFL (5 o’clock for right eye, and 7 o’clock for left eye) .

Group A,the differences among the three groups were statistically significant(P0.05). TCR,CCR,DAP,OD,BRC in Groups B and C showed trends of increasing,the differences in terms of the contents of BMP-RⅠamong the 3 phases were statistically significant(P0.05);the ER in Group B and C showed a trend of decreasing,thee difference between 4- and 8-week and 4- and 12-week were signifieantly dif- ferent(P0.05).Conclusion After application of glucocorticoid for a short term,pathological changes maintained and showed trends of inereasing in early stage.HBO can reverse these changes.The outcome of 3-course HBO therapy is better than that of 1-course therapy.
