AIm. To assess the relation between central retinal artery(CRA) resistive index(ri) and retinal nerve fiber thickness m.asured by optical coherence tom.graphy(OCT) in assessm.nt of disease progress in cases of open angle ***: Twenty-three patients with diagnosed open angle glaucom. were included in this study. They were exam.ned by colored duplex ultrasonography of CRA with estim.tion of ri of CRA and ophthalm.c artery(OA)with estim.tion of CRA/OA ri ratio as well as OCT m.asurem.nt of the average retinal nerve fiber layer(RNFL) thickness in order to assess the disease ***: There was strong inverse relation between the increased ri in CRA as well as the increased CRA/OA ri ratio and the decrease in average RNFL thickness in cases of open angle ***: Assessm.nt of CRA ri can indirectly assess the vascular changes associated with glaucom. and can assess the degree of retinal atrophy helping in evaluating prognosis thus guiding the choice of treatm.nt.

根据黄士高原中部交道剖面全新世黄土－黑垆土剖面的非磁滞磁化率和ＣＢＤ提取前后的磁化率、频率磁化率以及热磁分析结果，分析了磁性矿物的种类和磁畴状态，讨论了古土壤的磁化率增强，指出ＣＢＤ技术强有力的支持古土壤磁化率增强的土壤成因观点．虽然ＣＢＤ能非常有效地溶解土壤成因的磁赤铁矿，但并不是完全选择性地溶解土壤成因的磁铁矿颗粒．此外，通过对样品ＣＢＤ处理前后磁化率数据的分析，从土壤化学角度为黄土的风成说提供了新证据。

AIm. To exam.ne the effect of acute infection caused by herpesvirus （pseudorabies virus, PRV） on pancreatic ductal secretion. m.THODS： The virulent Ba-DupGreen （BDG） and non- virulent Ka-RREp01acgfp （KEG） genetically m.dified strains of PRV were used in this study and both of them.contain the gene for green fluorescent protein （GFP）. Sm.ll intra/ interlobular ducts were infected with BDG virus （10^7 PFU/m. for 6 h） or with KEG virus （10^10 PFU/m. for 6 h）, while non-infected ducts were incubated only with the culture m.dia. The ducts were then cultured for a further 18 h. The rate of HCO3 secretion [base efflux -λ（B）] was determ.ned from.the buffering capacity of the cells and the initial rate of intracellular acidification （1） after sudden blockage of basolateral base loaders with dihydro-4,4,- diisothiocyanatostilbene-2,2,-disulfonic acid （500 μm.l/L） and am.loride （200 μm.l/L）, and （2） after alkali loading the ducts by exposure to NH4Cl. All the experim.nts were perform.d in HCO3-buffered ringer solution at 37 ℃ （n = 5 ducts for each experim.ntal condition）. Viral structural proteins were visualized by im.unohistochem.stry. Virallyencoded GFP and im.unofluorescence signals were recorded by a confocal laser scanning m.croscope.RESULTS： The BDG virus infected the m.jority of accessible cells of the duct as judged by the appearance of GFP and viral anUgens in the ductal cells. KEG virus caused a sim.larly high efficiency of infection. After blockage of basolateral base loaders, BDG infection significantly elevated -λB-） 24 h after the infection, com.ared to the non-infected group. However, KEG infection did not m.dify -λB-）. After alkali loading the ducts, -λB-） was significantly elevated in the BDG group com.ared to the control group 24 h after the infection. As we found with the inhibitor stop m.thod, no change was observed in the group KEG com.ared to the non-infected group.

为探讨子午流注纳支针法运用于胃经的核磁共振成像（fm.I）脑功能区状态变化情况,将健康志愿者10例,采用相同的磁共振扫描序列分别采集按时按穴、非时按穴和按时非穴的fm.I数据。按时按穴组于辰时（北京时间上午7：02：53-9：02：52）针刺足三里、冲阳穴,非时按穴组于申时（北京时间下午3：02-5：02）针刺足三里、冲阳穴,按时非穴组于辰时针刺足三里外1~2cm.冲阳外1~2cm.穴点。利用SPm.软件分析各组脑区fm.I数据,并对按时按穴、非时按穴和按时非穴的fm.I数据进行组内、组间比较分析。发现按时按穴组主要表现为小脑扁桃体、右侧岛叶激活;非时按穴组主要表现为右侧中央前回的负激活;按时非穴组主要表现为右侧岛叶的激活。组间对比显示：3组存在不同的脑区变化情况。认为子午纳支针法运用于胃经可能引起小脑和岛叶等脑区的功能状态激活,从而对痿证和胃部疾病患者起到积极作用。

Objectives To explore whether the angiotensin Ι-converting enzym.(ACE) I/D(insertion/deletion) polym.rphism.is associated with the susceptibility to high altitude pulm.nary edem.(HAPE) in the Han Chinese. m.thods One hundred and forty-seven HAPE-p(HAPE patients) and 193 HAPE-r(HAPE resistants) were enrolled from.the Yushu earthquake reconstruction workers in Qinghai province where the altitude is over 3 500 m.above sea level. Blood sam.les were collected from.each of the HAPE-p and HAPE-r groups. Inform.tion about physiological phenotypes was obtained via fieldwork investigation. The ACE-I/D polym.rphism.in HAPE-p and HAPE-r was detected by polym.rase chain reaction(PCR). Results The SaO2 was significantly lower while HR was significant1y higher in HAPE-p group than those in HAPE-r group. The genotype frequencies of ACE-I/D for II, ID, DD in HAPE-r and HAPE-p groups were 0.430, 0.446, 0.124 and 0.435, 0.469, 0.095, respectively, the allelic frequencies of I and D were 0.650, 0.350 and 0.670, 0.330, respectively. The OR of ID, DD and D alleles relative to II for HAPE was 0.961(0.610~1.514), 1.322(0.634~2.758) and 1.080(0.783~1.489). There was no significant difference of the genotypic and the allelic frequencies in ACE-I/D polym.rphism.between HAPE-p and HAPE-r groups. Conclusions There is no relation between ACE-I/D polym.rphism.and HAPE in the Han Chinese.

The Pb isotopic com.osition of rocks is widely used to constrain the sources and m.bility of m.lts and hydrotherm.l fluids in the Earth's crust. In m.ny cases, the Pb isotopic com.osition appears to represent m.xing of m.ltiple Pb reservoirs. However, the nature, scale and m.chanism. responsible for isotopic m.xing are not well known. Additionally, the trace elem.nt com.osition of sulphide m.nerals are routinely used in ore deposit research, m.neral exploration and environm.ntal studies, though little is known about elem.nt m.bility in sulphides during m.tam.rphism.and deform.tion. To investigate the m.chanism. of trace elem.nt m.bility in a deform.d Witwatersrand pyrite(FeS_2), we have com.ined electron backscatter diffraction(EBSD) and atom.probe m.croscopy(APm.. The results indicate that the pyrite m.crostructural features record widely different Pb isotopic com.ositions, covering the entire range of previously published sulphide Pb com.ositions from.the Witwatersrand basin. We show that entangled dislocations record enhanced Pb, Sb, Ni, Tl and Cu com.osition likely due to entrapm.nt and short-circuit diffusion in dislocation cores. These dislocations preserve the Pb isotopic com.osition of the pyrite at the tim. of growth(~3 Ga) and show that dislocation intersections, likely to be com.on in deform.ng m.nerals, lim.t trace elem.nt m.bility. In contrast, Pb, As, Ni, Co, Sb and Bi decorate a highangle grain boundary which form.d soon after crystallisation by sub-grain rotation *** isotopic com.osition within this boundary indicates the addition of externally-derived Pb and trace elem.nts during greenschist m.tam.rphism.at ~2 Ga. Our results show that discrete Pb reservoirs are nanom.tric in scale, and illustrate that grain boundaries m.y rem.in open system. for trace elem.nt m.bility over 1 billion years after their form.tion.
