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.

Objective To compare the difference of procalcitonin (PCT)level between serum and plasma in children so as to in-vestigate whether ethylenediamine tetraacetic acid dipotassium (EDTA-K2 )anti-coagulation plasma could replace serum to be an al-ternative material for PCT testing.Methods The PCT concentrations in the serum and EDTA-K2 anti-coagulation plasma from 90 children patients were detected by using the mini-VIDS-GB automatic enzyme linked fluorescence analyzer and the plasma PCT au-tomatic quantitative detection method.The correlation between the two sets of data was analyzed.And the data were assigned into the 3-level groups for conducting statistic analysis.At the same time the influence of child′s age and gender on the PCT level was al-so discussed.Results The PCT level in serum was well correlated with that in EDTA-K2 anti-coagulation plasma (r=0.812,P <0.05).There were no statistically significant differences in PCT levels between serum and plasma measured in the low level groups (P >0.05).However,the differences of the PCT levels between serum and EDTA-K2 anti-coagulation plasma in the middle level group and high level group were statistically significant (P <0.05).Child′s gender and age have significant effect on the PCT level. Conclusion There is statistically significant difference between serum and plasma PCT detection levels in children,which has an important guiding role for further systematic study of PCT level difference in serum and EDTA-K2 anticoagulation plasma and its clinical significance.

Objective To explore the feasibility of amide proton transfer (APT) MR imaging for the detection of basal ganglia abnormalities in patients with Parkinson' s disease (PD).Methods Twentyseven patients with PD and twenty-three age-matched normal control subjects underwent cerebral APT and structural MR imaging.The magnetic resonance ratio asymmetry (MTRasym) values at 3.5 ppm of bilateral globus pallidus,putamen and caudate were measured on APT images.MTRasym (3.5 ppm) values of cerebral structures between PD patients and control subjects were compared with independent-samples t test.Paired-samples t test was used to compare the difference of MTRasym (3.5 ppm) between the side of onset and contralateral side in patients with PD.The difference of MTRasym (3.5 ppm) among normal controls,early-stage PD,and advanced-stage PD patients was assessed with one-way analysis of variance.Results Compared to normal controls,MTRasym(3.5 ppm) values of globus pallidus,putamen and caudate were significantly increased in PD patients ((0.89 ±0.12)％ vs (0.57 ±0.16)％,(1.05 ± 0.11)％ vs (0.82 ± 0.15)％,(1.15 ±0.13)％ vs (0.78 ±0.19)％; t =3.311,2.562,3.277 respectively,all P values ＜ 0.05).Significant differences in MTRasym (3.5 ppm) values of these cerebral structures were observed among normal controls,early-stage PD and advanced-stage PD patients.And MTRasym (3.5 ppm) values in globus pallidus,putamen and caudate were significantly higher in early-stage PD patients than normal controls.In PD patients,even not statistically significant,MTRasym (3.5 ppm)values of sides of onset were slightly lower than contralateral sides.Conclusions APT MR imaging can sensitively identify the difference of MTRasym (3.5 ppm) in the basal ganglia between PD patients and normal controls.APT might be a useful tool to evaluate abnormal metabolite in basal ganglia of PD patients.

Objective To explore the feasibility of amide proton transfer (APT) MR imaging to detect cerebral abnormality of the substantia nigra and red nucleus in patients with Parkinson disease (PD). Methods Twenty-seven patients with PD and twenty-three age-matched healthy control subjects were recruited in this study. According to Hoehn&Yahr stages, PD group was divided into two subgroups:early-stage(n=14) and advanced-stage(n=13). PD with right limb onset were seen in 14 patients, and PD with left limb onset in 13 patients. All the PD patients and healthy controls underwent brain APT MR imaging. The magnetic resonance ratio asymmetry (MTRasym) values at 3.5 ppm of bilateral substantia nigra and red nucleus were measured on APT images. MTRasym(3.5 ppm)values of substantia nigra and red nucleus between PD patients and control subjects were compared with independent-samples t test. The difference of MTRasym(3.5 ppm)among normal controls, early-stage PD, and advanced-stage PD patients was assessed with one-way analysis of variance. Paired-samples t test was used to compare the difference of MTRasym (3.5 ppm) in substantia nigra and red nucleus between the side of onset and contralateral side in PD patients. Results Compared to normal controls, MTRasym(3.5 ppm) values of substantia nigra significantly decreased in PD patients[(0.96±0.35)%vs. (1.20±0.39)%respectively, t=-2.093 P=0.039]. No significant differences in MTRasym (3.5 ppm) values of red nucleus were observed between normal controls and PD patients[(0.97 ± 0.36)% vs. (1.09 ± 0.38)% respectively, t=-1.148, P=0.254]. Significant differences in MTRasym(3.5ppm) values of these cerebral structures were observed among normal controls, early-stage PD and advanced-stage PD [substantia nigra(1.20±0.30)%,(1.09±0.32)%and(0.81±0.37)%respectively, F=3.954, P=0.022;red nucleus(1.09±0.28)%,(1.21±0.35)%and(0.71±0.33)%respectively, F=7.563, P=0.001]. MTRasym(3.5 ppm) in substantia nigra showed a consistently decreasing tendency from normal controls to early-stage PD, to advanced-stage PD. MTRasym(3.5 ppm) values of sides of onset and contralateral sides of substantia nigra and red nucleus in PD patients had no significant statistically difference (substantia nigra(0.93 ± 0.33)% vs.(0.99 ± 0.30)%, t=-0.660, P=0.515; red nucleus(1.01 ± 0.36)% vs.(0.93 ± 0.29)%, t=0.545, P=0.590). Conclusions APT MR imaging can show sensitively the difference of MTRasym (3.5 ppm) in substantia nigra and red nucleus between early PD patients and normal controls, Thus, APT is a useful tool to diagnose PD and monitor the disease progression.

Objective To explore the correlation between the two methods of pulmonary arterial thermodilution technique(ThDCO)and pulse indicator continuous cardiac output(PiCCO)in determining hemodynamic changes in patients undergoing orthotopic liver transplantation(OLT).Methods Eighteen patients with end-stage liver disease(ASAⅡ-IV)were performed OLT and monitored hemodynamic changes by PiCCO method and ThDCO method simultaneously.The hemodynamic parameters including mean arterial pressure(MAP),cardiac output(CO)and systemic vascular resistance(SVR)were measured at different time points before anesthesia induction,after tracheal intubation,after the beginning of operation,at anhepatic phase,at neohepatic phase,at the end of operation,and after operation.Results Good correlation was found between the two methods for the determination of CO and SVR(r=0.987,P0.05).Conclusion The hemodynamics change dramatically in patients undergoing OLT.There is good correlation between the two methods of PiCCO and ThDCO for perioperative hemodynamic monitoring in patients undergone OLT,and PiCCO detection can be used conveniently for real-time continuous monitoring.

Objective To investigate the standardized treatment of 33 children with thalassemia and their family financial burden registered in Bao'an district, Shenzhen city, and to provide basic information for formulating health policy for the government. Methods In 2009, preliminary investigations on 39 registered families with thalassemia children were conducted by telephone, and a household survey was made to collect treatment and economic status by questionnaire on 33 children. Results Among 33 cases of thalassemia children, 21 cases(63.7%) were severe anemia, 5 cases( 15.1%) in need of care or special care, and 25 cases(75.8%) were difficult or unable to maintain standardized treatment. The average family monthly income and expenditure was (4060 ± 2002) and (4926 ± 2991) yuan, respectively. The average monthly treatment costs were (2665 ± 1872) yuan, and the average debt amounted to (64 600 ± 53 940) yuan. Fifteen families[60.0%(15/25)] would reduce the times of blood transfusions or iron transpirations when they encountered revenue deficiency. Conclusions The heavy economic burdens on families with children thalassemia result in inadequate or interrupted treatment on sick children and affect their survival and quality of life, which should be taken more attention and social care.

OBJECTIV: e To find the correlation between real best corrected visual acuity (BCVA) and testing results of microperimetry and visual evoked potential (VEP) and to explore a new method in recording BCVA in macular disease. METHODS: Sixty-two patients with macular disease (macular disease group, 62 eyes) and eighteen healthy volunteers (control group, 36 eyes) had BCVA, microperimetry and VEP recorded. RESULTS: (1) By microperimetry, the values of retinal mean sensitivity and fixation percentage in macular disease group were lower than that in control group. The bicurve ellipse area in macular disease group was higher than that in control group. By VEP, P100 amplitude under 0.5 cpd and 2 cpd in macular disease group were significantly higher than that in control group and the latency was prolonged (P < 0.05). (2) In macular disease group, BCVA had significant positive correlation with retinal mean sensitivity, bicurve ellipse area, macular central 2 degrees and 4 degrees fixation percentage, respectively (P < 0.05). There was a significant correlation between retinal mean sensitivity and P100 amplitude (P < 0.05). (3) Multiple linear regression equation was y = 0.053 x1+0.008 x3+3.897 (y was BCVA, while x1 was retinal mean sensitivity and x3 was P100 amplitude under 2 cpd). CONCLUSION Combined use of microperimetry and VEP is useful in the assessment of BCVA in macular disease.
