Objective To evaluate the imaging features of patients with vascular cognitive impairment (VCI) induced by Subcortical Ischemic Vascular Disease (SIVD), through magnetic resonance diffusion tensor imaging ( DTI ) and proton spectroscopy ( MRS ) technology. Methods A total of 52 patients with SIVD were enrolled. After analysis of scale score, 32 patients with cognitive impairment were assigned to VCI group and 20 patients with no cognitive impairment were assigned to control group. Both group received DTI and MRS examination. The mean values of apparent diffusion coefficient (ADC) and fractional anisotropy (FA) of the bilateral temporal, frontal, parietal and occipital white matter regions as well as in the bilateral centrum semiovale were calculated. The peak value of MRS of N-acetyl aspartate (NAA) , choline ( Cho), creatine (Cr) and phaseomannite ( mI ) were calculated. Results Compared with control group, FA decreased in the region of temporal, frontal, parietal as well as in the centrum semiovale , and ADC increased in VC[group ( P < 0.05 ) . In the frontal regions and centrum semiovale,the VCI patients had a significant FA decrease. The ADC value increased obviously in the temperal lobe.Spectrum analysis results showed, NAA/Cr was lower than control group in VCI group in the frontal lobe (1.43 ±0.08 vs 1.53 ± 0. 92), while mI/Cr was higher than control group in the temporal lobe(0. 51 ±0. 06 vs 0. 46 ± 0. 07 ) ( P < 0. 05 ). Conclusion FA in the temporal and centrum semiovale regions of VCI group and NAA in the temporal white matter regions decreased obviously. DTI and MRS could provide a reference value for early diagnosis and assessment of VCI.

Our laboratory isolated three defensin molecules from the circulating neutrophils of healthydonors.The three molecule mixture was conjugated with BSA and immunized New Zealand rab-bit.ELISA showed that the rabbit antisera was of a very high titters,which were specific for hu-man defensins.Immunoperoxidase staining with this rabbit antisera indicated that normal humanneutrophils,acute myeloid leukemia cell lines KG1 and HL-60 were highly positive.In con-trast,normal mononuclear leukocytes,erythrocytes,erythroleukemia cell line K562 were all neg-ative,even rabbit and guinea pig neutrophils had no response to this rabbit anti-human de-fensins antisera.Our preliminary experiments suggested that the rabbit antisera was highly spe-cific for human defensins.Probably,defensin is a differentiation antigen of granunocyte lineage,and antibody against human defensins would be a candidate immunological reagent specific for a-cute myeloid leukemia.Further work for this should be done.

Objective To analyze the genetic characterizations of wild type measles viruses caused the measles outbreak in Xinjiang. Methods Vero/Slam cell were used for measles viruses isolation from the specimens collected from measles outbreaks patients. Fragment of 676 nucleotide acids of the carboxylend of nucleoprotein gene were amplified using reverse transcription-polymerase chain reation (RT-PCR) method and then the PCR products were directly sequenced and analyzed. Phylogenetic tree was constructed based on 450 nucleotide acids of the N-terminus of nucleoprotein gene, and homological analysis was performed at nucleotide acid level. Results 11 measles viruses were sequenced and all belonged to H1a subgenotype.The nucleotide difference was 0-0. 2% between 11 Xinjiang isolates. And the nucleotide difference was 2.2%-2.4% between Xinjiang isolates and H1 genotype reference strain. Conclusion The Measles viruses causing the measles outbreak in Xinjiang were H1a subgenotype.

OBJECTIVETo compare the difference in clinical efficacy on children attention deficit hyperactivity disorder (ADHD) between the combined therapy of scalp acupuncture and EGG biofeedback and the simple EEG biofeedback therapy so as to search the better therapeutic method for ADHD.
METHODSOne hundred patients were randomized into an observation group and a control group, 50 cases in each one. In the control group, the simple EEG biofeedback therapy was adopted. In the observation group, on the basis of biofeedback therapy, scalp acupuncture was added and applied to Dingzhongxian (MS 5), Dingpangyixian (MS 8), Baihui (GV 20), Sishencong (EX-HN 1), etc. The ten treatments made one session. After four sessions of treatment, FIQ value in Wechsler intelligence scale, CIH score in Conners children behavior questionnaire, the ratio of 0 wave and p wave in EEG, FRCQ and FAQ in the integrated visual and auditory continuous performance test (IVA-CPT) and clinical comprehensive efficacy were observed before and after treatment in the two groups separately.
RESULTSThree cases were dropped out in the observation group and 2 cases were out in the control group. In the two groups, FIQ, FRCQ and FAQ were all increased after treatment (P < 0.01, P < 0.05); the increases in the observation group were much more significant than those in the control group after treatment (all P < 0.05). In the two groups, CIH score and the ratio of 0 wave and p wave were all reduced after treatment (P < 0.01, P < 0.05); the reduction in the observation group were much more apparent as compared with those in the control group (both P< 0.05). The total effective rate was 91.5% (43/47) in the observation group and better than 83. 3% (40/48, P < 0.01) in the control group.
CONCLUSIONThe combined therapy of scalp acupuncture and EEG biofeedback achieves the superior efficacy on children ADHD as compared with the simple biofeedback therapy. This combined therapy rapidly relieves the essential symptoms of ADHD and improves EEG waveform in children patients. Importantly, this therapy obtains and consolidates the significant efficacy.

AIM: To evaluate the ability of spectral domain optic coherence tomography ( SD-OCT ) parameters to detect progressive structural damage in primary open angle glaucoma ( POAG) by contrasting with visual field. ·METHODS: Retrospectively we evaluated 48 subjects (48 eyes ) of POAG, followed up 14 to 62mo. The parameters of SD-OCT and visual field were obtained. The correlation between the change of visual field measurements and OCT measurements were analyzed. Visual field progression was defined as reproducible drop of at least 2dB of mean deviation (MD) from the baseline visit. ROC curve was made to evaluated the ability of OCT parameters in detect progression of POAG. ·RESULTS: The 25 eyes were classified in progression group and 23 eyes were in non-progression group. No significant correlation was seen between OCT parameters and visual field in non-progression group. In progression group, OCT parameters which were significantly correlated with MD reduce were rim volume ( r=-0. 5997, P=0. 0007), C/D vertical ratio (r=-0. 6309, P=0. 0003), RNFL(r= 0. 4201, P= 0. 0260), and GCC(r= 0. 7080,P<0. 01). ROC curves showed the GCC reflected the reduce of MD accurately (P=0. 013). ·CONCLUSION: Part parameters of SD-OCT can reflect the progression of POAG accurately and provided a new method to detect the damage of visual function of POAG.
