我校资产管理网络化的初步实现

1背景随着国家对教育投入逐年增加,特别是近年来重大科研项目如211工程、985项目等大批经费用于设备添置,学校固定资产急剧膨胀。同时高校规模不断拓展,综合性高校拥有2个以上校区的情况非常普遍。在这种情况下沿用旧的单机管理模式,     

Sympathoadrenal excitation and inhibition by lower brainstem stimulation in cats

Effects of stimulation of brainstem sites on hemodynamics and plasma catecholamine levels were assessed in cats under chloralose-urethane anesthesia. Pressor areas of the dorsal medulla (DM) and ventrolateral medulla (VLM) and the depressor area of the paramedian reticular nucleus (PRN) were stimulated electrically using a monopolar electrode, or chemically using sodium glutamate microinjection. Plasma levels of norepinephrine (NE) and epinephrine (EPI) were measured in caval blood above the adrenal veins. Electrical stimulation of the DM and VLM produced increases in blood pressure and in plasma NE and EPI levels that were enhanced after acute vagotomies. The NE and EPI responses were attenuated after acute, bilateral adrenalectomies, confirming augmented adrenomedullary secretion, whereas the pressor responses were intact. Injection of sodium glutamate into the same pressor regions of the DM or VLM also produced pressor responses and elevated plasma catecholamine levels, indicating that the responses resulted from activation of neuronal perikarya. Stimulation of the PRN attenuated pressor and catecholamine responses during stimulation of the DM and VLM. The results indicate that pressor responses during stimulation of the DM and VLM are due at least partly to activation of perikarya in these regions, are associated with but not dependent on adrenomedullary activation, and are enhanced after vagotomy; and that neurons of the PRN exert inhibitory modulation of the pressor and adrenomedullary responses during stimulation of VLM and DM.

高血压病人药物治疗期间动态血压变化

目的评价高血压病人药物治疗期间２４ｈ动态血压变化。方法２６例住院的高血压病人经药物治疗４周连续３ｄ随测血压，血压正常后进入本研究。治疗前后进行２４ｈ动态血压监测。结果患者随测血压（８～９ＡＭ，３～４ＰＭ）血压恢复到正常水平，但动态血压显示在一段时间内（６～８ＡＭ，６～１１ＰＭ）平均收缩和舒张压仍明显高于正常人平均水平（Ｐ＜０．０１），而该时间段易被临床医生忽视。结论随测血压不能实际全面反映高血压病人药物治疗的疗效，２４ｈ动态血压的监测可以正确评价高血压病人药物治疗的效果并根据高血压分布的时间来调整降压药的种类和剂量。     

奶茶对大鼠体重和血清胆固醇含量的影响

目的 :探讨奶茶对大鼠体重和血清胆固醇含量的影响。方法 :将大鼠随机分为对照、脂对照、奶、茶和奶茶五组 ;高脂饲养的同时分别用水、奶、茶和奶茶进行灌胃 ,定期测定大鼠的血清胆固醇 (TC)。结果 :实验期间奶茶组大鼠体重的增长量高于其他三个高脂饲料组 ,且明显高于对照组 (P <0 .0 5 ) ;高脂饲料组大鼠的血清胆固醇含量明显增加 ,但增长量在高脂饲料组间差异无显著性 (P >0 .0 5 )。结论 :本实验浓度的奶茶对高脂饲料诱导的大鼠血清胆固醇升高未见有降低作用

Acute pericarditis as initial clinical manifestation of hypereosinophilia syndrome]

The case of a patient in whom acute pericarditis was the initial manifestation of an idiopathic hypereosinophilia is reported. Endomyocardial abnormalities were not found by echocardiography. Response to prednisone therapy was good; symptoms, pericardial effusion and eosinophilia early disappeared after therapy. Some clinical aspects of this uncommon disease are discussed.

A mixing model for polychlorinated dibenzo-p-dioxins and dibenzofurans in surface sediments from Newark Bay,New Jersey using polytopic vector analysis

The identity and relative contributions of various sources of polychlorinated dibenzo-p-dioxins (PCDDs) and dibenzofurans (PCDFs) to recently deposited sediments collected in Newark Bay and its major tributaries were determined using polytopic vector analysis (PVA), a multivariate statistical technique relatively new in the chemometric literature. The concentrations of 2,3,7,8-substituted PCDD/Fs were assayed in eighty-one surface and near-surface sediment samples collected from the Passaic River, Hackensack River, Arthur Kill, Elizabeth River, Kill Van Kull, Port Elizabeth, and Port Newark navigation channels and Robins Reef, which is located in New York Harbor. PVA modeling revealed five predominant 2,3,7,8-substituted PCDD/F fingerprint patterns in geographically plausible distributions throughout the estuary. This was consistent with the current understanding of hydrodynamic and sedimentation conditions reported in the literature for Newark Bay. Three patterns contained 2,3,7,8-tetrachlorodibenzo-p-dioxin (2,3,7,8-TCDD), which is alleged to originate from a single industrial source on the lower Passaic River. One of the fingerprints containing 2,3,7,8-TCDD was present in moderate proportions (10–20%) in surface sediments near the site, but was generally observed in low abundance (<5%) elsewhere in the estuary. A fingerprint pattern characteristic of PCDD/F profiles in effluents from municipal sewage and waste water treatment plants was widely distributed in the estuary, but reached its highest relative proportions in the Elizabeth River. A third fingerprint pattern was highest in the Arthur Kill and lower Passaic River and closely matched the residue patterns found in several types of combustion sources. A fourth finger-print pattern in Hackensack River and lower Passaic River sediment matched the PCDD/F profile reported in PCB Aroclor^® formulations. A fifth fingerprint pattern matched the profile in recycled pulp and paper mill effluents and was highest in Kill van Kull and upper Passaic River sediment. The majority of PCDD/Fs in sediment from Reaches B, C, and D of Port Newark and Port Elizabeth were attributable to sediments transported via the Arthur Kill and the Kill Van Kull. These results are consistent with those previously reported using principal components analysis, which indicated that 2,3,7,8-substituted PCDD/F patterns in the sediments of Newark Bay are consistent with discharges from multiple sources.
