标题:Surgical Treatment Of Severe Acute Pancreatitis: Timing Of Operation Is Crucial For Survival
摘要:Background: In Patients Operated On For Severe Acute Pancreatitis (Sap) The Impact Of The Timing Of Operation On Outcome Is Controversial. Materials And Methods: In A Retrospective Analysis Of A Prospectively Documented Database,We Studied 250 Patients Suffering From Sap,Who Were In Need For Surgical Treatment During Their Course Of Disease. Results: From 1982 To 1998,250 Patients With The Diagnosis Of Sap Who Required Operative Treatment Were Admitted To The Intensive Care Unit (Icu) Of A University Hospital. The Mean Apache Ii Score On The Day Of Admission Was 16.1 (8-35). One Hundred Eighty-Five Patients (74%) Required Reoperation,Of Whom 111 Patients (60%) Underwent Reoperation On Demand And 74 (40%) Patients A Pre-Planned Reoperation. Overall Mortality Was 38.8% (97 Patients). In Patients Who Were Operated During The First Three Weeks After Onset Of Disease,Mortality Was Significantly Higher Than In Patients Who Were Operated After Three Weeks (46% Vs. 25%,P < 0.01). Besides Patient Age (P < 0.05),Apache Ii Score At Admission (P < 0.01),Multiple Organ Dysfunction (P < 0.01),Infection Of Pancreatic Necrosis (P < 0.05),Surgical Control Of Pancreatic Necrosis (P < 0.0001),And The Time Of Surgical Intervention (P < 0.05) Determined Survival Significantly. Conclusion: Patients Who Were Operated Later Than Three Weeks After Onset Of Disease Had A Significantly Better Outcome. In Patients Suffering From Sap Who Required Surgical Treatment,The Timing Of Operation Is Crucial For Survival.

摘要:The disclosure generally relates to rechargeable batteries, for example, lithium-ion batteries including electrolytes with deuterated solvents. The use of deuterated solvents in the synthesis of lithium-ion electrolytes in rechargeable cells or batteries increases the chemical stability of the cell or batteries by reducing the rate of hydrogen related reactions during decomposition or inhibiting some of these parasitic reactions.

摘要:The present application relates to the technical field of batteries, and in particular to a carbon/Berlin blue-like composite material and a preparation method therefor and use thereof. The preparation method comprises the following steps: preparing a carbon material, a chelating agent and a transition metal salt into a first mixture dispersion liquid, and carrying out a first hydrothermal reaction to obtain a carbon-transition metal composite precursor; and preparing alkali metal-ferrocyanide and the carbon-transition metal composite precursor into a second mixture dispersion liquid, carrying out a second hydrothermal reaction, and carrying out post-treatment to obtain the carbon/Berlin blue-like composite material. According to the preparation method, by means of a hydrothermal method, a solid-phase precursor is firstly synthesized. The rate of the carbon-transition metal composite precursor in the conversion process is relatively low, facilitating the slow formation of Berlin blue-like crystal lattices, and reducing the structural defects of ferrocyanide vacancy and crystal water easily occurring in the Berlin blue-like synthesis process. Meanwhile, the carbon material is provided for uniform compounding, so that the electrical conductivity is improved, the cycle performance and the stability are improved, and the method is suitable for large-scale production.

摘要:The present invention provides an industrial process for effectively and advantageously preparing optically active 1-substituted amino-2,3-epoxypropanes useful as intermediates for preparing agricultural chemicals and medical products from optically active 1-substituted amino-2,3-propanediols used as raw materials. The present invention also provides useful intermediates. Specifically, an optically active 1-substituted amino-2,3-propanediol (1) is reacted with an orthoacid ester (2) or thionyl chloride (3) to produce a cyclic optically active compound (4), and then a compound (5) containing a halogen atom is prepared by reaction with a ring-opening reaction agent having an ability to introduce a halogen atom X. Finally, an optical active 1-substituted amino-2,3-epoxypropane is prepared by ring-closure reaction in the presence of a base.

摘要:Compounds of formula (I)n having only two optically active centres, may exist as four isomers, each of which may be prepared by resolving a racemic amino-diester intermediate in the preparation thereof. The racemic amino-diester is selectively hydrolysed to the corresponding mono-ester which is acylated and subsequently selectively deacylated to produce the resolved mono-ester. n Isomers of compounds of formula (I) having a particular configuration are biologically more active than the corresponding isomers having other configurations and are useful in medicine, either as the raw compound or in a pharmaceutical formulation, for example in inhibiting platelet aggregation.
