糖尿病药物的分类按作用机制分类：常用口服抗糖尿病药物的分类1.促进胰岛β细胞分泌胰岛素的制剂磺脲类降糖药（SUs）餐时血糖调节剂（瑞格列奈、那格列奈）2.促进外周组织增加葡萄糖利用的药物双胍类（二甲双胍）3.抑制肠道葡萄糖吸收的药物α-糖苷酶抑制剂4.胰岛素增敏剂（TZDs）噻唑烷二酮类，双胍类1.1胰岛素促泌剂通过作用于胰岛β细胞膜受体，促使胰岛素释放，从而产生降糖效果，SUsSU是治疗T2DM的主要药物之一。餐时血糖调节剂新型降糖药----那格列奈、瑞格列奈1.1.1磺脲类药物的降糖机制胰腺内作用机制：促使β细胞ATP敏感的钾离子通道关闭，刺激胰腺β细胞释放胰岛素；胰腺外作用机制：增加外周葡萄糖利用，第1、2代可能继发于葡萄糖毒性作用的改善。第三代亚莫利可增加胰岛素敏感性。couplingCentreshallbechecked,thesecondpouredconcretestrengthofmorethan70%.Intheprocessofreamingorboring,apartfromthespecialprovisionsinfactory,doesnotallowanyworkthatmayaffectthecouplingCentre,suchasirrigation,tocylinderconnectionstofloodthecondenserpipesandsoon.Wellboring,hingeboltholeflangewithcouplingofvertical,notoblique.Mountingboltsshouldbeaddedlubricants,typinggentlywithasmallhammer,nottoolooseortootight,packedtheboltswiththecorrespondingsealscrewholeshouldbemarked.6.4.5.4.2couplingreamedandpairingsisclosetothediameterofboltbearinggoodhingeholes,dressedwithagoodtwocouplingboltsbeforeyoucanmovetherotor,boring-reamingholeinturn.Couplingboltsmustbetightcouplingissymmetricaldiameter,inboring,reaming,twoboltsout.Wellboring,hingeboltholeflangewithcouplingofvertical,notoblique.Duetothecouplingboltsinaccordancewithhingeholescorrespondingtothediameterofthescrewholesonebyoneafterprocessing,processingbackboltinstallationlocationcannotbechanged,soaccordingtoboltaftertheactualweightdifferenceofnutandlockwashertomatch.Generalrequirementsforcouplingtwosymmetricaldiameterbolt,nutandlockwasher'stotalweightdifferenceshouldnotbegreaterthan10gandknocksstampedmark.(SeFigure18)Thecouplingboltsapplylubricant,andthengentlywithcopperhome,nottoolooseortootight.BoltAssemblyisfinished,symmetricaltighteningallboltsto30%,50%,70%,10%force,andcheckthecouplingflutterandbeforeconnectingthecirclegraduallychangesitsvalueshouldbelessthan0.02mm.Tighteningtorqueofthecouplingboltsshallcomplywiththetechnicalrequirementsmanufacturersdrawings,withadynamometricwrenchorlogtensiontools.Threwhelrotorswingtestcouplingconnectionsshouldbechecked:takingleave,1.1.2磺脲类药物适应症可作为非肥胖2型糖尿病的一线用药（首选）；老年患者或以餐后血糖升高为主者宜选用短效类，如格列吡嗪、格列喹酮；轻－中度肾功能不全患者可选用格列喹酮；病程较长，空腹血糖较高的2型糖尿病患者可选用中－长效类药物（如格列本脲、格列美脲、格列齐特、格列吡嗪控释片）。FPG＜13.9mmol/L、有较好的胰岛功能、新诊断糖尿病、胰岛细胞抗体(ICA)或谷氨酸脱羧酶抗体(GADA)阴性的糖尿病患者对磺脲药物反应良好。1.1.3禁忌症1型糖尿病患者；妊娠糖尿病或其他特殊类型糖尿病；2型糖尿病患者有严重肝肾功能异常者；对磺脲类降糖药物过敏者；在发生糖尿病急性合并症如糖尿病酮症酸中毒时，或并有严重慢性合并症者；在有应激情况下，如有严重创伤、大手术、严重感染等。1.1.4副作用couplingCentreshallbechecked,thesecondpouredconcretestrengthofmorethan70%.Intheprocessofreamingorboring,apartfromthespecialprovisionsinfactory,doesnotallowanyworkthatmayaffectthecouplingCentre,suchasirrigation,tocylinderconnectionstofloodthecondenserpipesandsoon.Wellboring,hingeboltholeflangewithcouplingofvertical,notoblique.Mountingboltsshouldbeaddedlubricants,...
