晚期肿瘤住院病人护患纠纷的防范

我院肿瘤科是以中医调护来治疗晚期肿瘤患者。大多数病人都已尝试了各种治疗后(如手术、放疗、化疗后)病情仍在恶化。为延长生存、延续生命报有一线希望来向我院中医求治,因此晚期肿瘤病人是一个特殊的群体。在护理管理方式、护理措施上有其特殊性。护患之间在护理措施上常出现不同认识,随着《医疗事故处理条例》的贯彻实施,病人及其家属的维权意识不断增强,易产生护患纠纷。现将护患易发生纠纷的原因及防范措施分析及探讨如下。1原因分析1.1晚期肿瘤病人因长期的病痛折磨,情绪悲观,失去了战胜疾病的信心,许多病人一旦得知自己所患疾病是恶…     

几种中药的灵活应用

中医药文化博大精深,就中药来说,每味都有它特殊的功效主治,同一味药物由于产地不同,炮制不同,往往作用也有差异.下面简单的举四味中药以便说明.     

重症胆管炎23例临床治疗分析

目的：探讨急性重症胆管炎患者的手术时机和死亡原因。方法：回顾性分析23例急性重症胆管炎患者的治疗及预后情况。结果：死亡2例（手术死亡及传统治疗死亡各1例）。早期大剂量短期应用糖皮质激素患者休克得到纠正率85％，明显高于未用糖皮质激素患者休克纠正率50％。结论：急性重症胆管炎患者应在出现休克和（或）精神症状之前手术，对已出现休克的患者，应先给予充分的保守治疗，待病情稳定后再手术。贻误手术时机，严重合并症如多器官功能衰竭及高龄是死亡的主要原因。     

Characterization of a novel metabolite intermediate of ziprasidone in hepatic cytosolic fractions of rat, dog, and human by ESI-MS/MS, hydrogen/deuterium exchange, and chemical derivatization.

Ziprasidone (Geodone), a novel atypical antipsychotic agent, is recently approved for the treatment of schizophrenia. It undergoes extensive metabolism in preclinical species and humans after oral administration, and only a very small amount of administered dose is excreted as unchanged drug. In vitro studies using human liver microsomes have shown that the oxidative metabolism of ziprasidone is mediated primarily by CYP3A4. However, coadministration of ziprasidone with ketoconazole, a CYP3A4 inhibitor, showed only a modest increase in its exposure. Therefore, in vitro metabolism of ziprasidone was investigated in hepatic cytosolic fractions to further understand its clearance mechanisms in preclinical species and humans. The major metabolite from incubation of ziprasidone in cytosolic fractions of rat, dog, and human was characterized by liquid chromatography-tandem mass spectrometry and found to be the product of reductive cleavage. Derivatization and hydrogen/deuterium exchange were used to deduce that the addition of two hydrogen atoms had occurred at the benzisothiazole moiety. Further studies to determine the enzyme involved in the formation of this metabolite are currently in progress. The identification of this novel metabolite in cytosol has clarified the clearance mechanism of ziprasidone in humans and preclinical species.     

PBL在泌尿外科教学查房中的应用

以问题教学为基础的教学(Prob lem-Based Learn ing,PBL)是将整个教学过程纳入到真实的临床问题中,并围绕若干问题,在教师的指导下完成教学的方式[1-2]。长期以来在我国的高等教育中,一直采用“填鸭式”教学,它往往缺乏活力,缺乏时代的气息,教材内容重复,知识成旧,忽视因材施教     

胰岛素强化治疗在2型糖尿病骨折患者围手术期的应用

Objective To investigate the best way to control the blood sugar level during the perioperation of bone fracture patients with type 2 diabetes(T2DM).Methods Bone fracture patients with T2DM were randomly divided into three groups:continuous subcutaneous insulin infusion group(insulin aspart,group CSII,n=20),glargine treatment group(insulin aspart+insulin glargine,group GA,n=20),and NPH treatment(insulin aspart+rh-insulin,group NA,n=20).The levels of fasting plasma glucose(FPG)and the 2 hours postprandial glucose(2h PG),blood glucose fluctuation(BGF),insulin dosage(ID),good effective time(GET),incidence of hypoglycemia,dawn phenomenon and infection,average time of stitches removal(ATSR),average hospitalized length(AHL)of three groups were compared.Results FPG and 2hPG,ID in group CSII[(6.32±1.18)mmol/L,(7.72±1.53)mmol/L,(35.40±1.60)IU]and group GA [(6.25±0.88)mmol/L,(7.32±1.17)mmol/L,(36.20±0.80)IU]were significantly lower than those of group NA [(7.44±1.36)mmol/L,(8.52±0.76)mmol/L,(40.50±2.40)IU,all P<0.05],simulaneously,BGF,GET incidence of complications,ATSR,AHL of group CSII and GA were significantly lower than those of group NA(all P<0.05).There were not significant difference between group CSII and group GA.Compared with group CSII,group GA had less costs in-hospital and better practicability.Conclusion Both CSII and insulin glargine combined with insulin aspart can effectively,safely,rapidly and stablely control hyperglycemia.and might be the first choice to control blood sugar for bone fracture patients with T2DM in perioperation.     

神经内结缔组织增生与三叉神经脱髓鞘的关系

目的探讨三叉神经痛（trigeminal neuralgia，TN）患者三叉神经患支内结缔组织改变与神经脱髓鞘的关系。方法对手术切取的TN患者三又神经患支标本及对照标本行髓鞘染色，在光镜及电镜下观察神经横截面形态改变，并采用图像分析仪进行半定量测量。结果形态观察及图像分析结果都显示TN患者三叉神经患支明显脱髓鞘，神经内结缔组织显著增生，F检验证实二者存在显著线性正相关。结论TN患者三叉神经惠支内神经内结缔组织增生，可能是TN发生的重要机制之一。     

早期短程应用美洛培南治疗严重烧伤的临床对比研究

目的研究早期短程应用美洛培南对严重烧伤的治疗效果。方法前瞻性地选择特重度以上烧伤患者49名。治疗组21名伤后24h应用美洛培南3～5天。对照组28名，伤后24h应用头孢三、四代抗生素3～5天。观察患者SIRS、创面脓毒血症、MODS发生率，死亡率及治愈好转率。结果治疗组SIRS发生率与对照组比较无差异，创面脓毒血症、MODS发生率及死亡率显著低于对照组，治愈好转率明显高于对照组。结论早期短程应用美洛培南可以减少创面脓毒血症、MODS的发生，降低死亡率，提高严重烧伤患者的治愈好转率，对SIRS的发生率影响不大。

肱骨近端骨密度的测量及其与年龄和体质量指数的相关性研究

目的 建立一种肱骨近端骨密度(BMD)的测量方法,研究肱骨近端BMD与年龄和体质量指数(BMI)的关系,探讨肱骨近端BMD在预报骨质疏松症的敏感性.方法 选择绝经后健康女性志愿者,使用Hologie DELPHI-A双能X射线骨密度仪及本研究设计的肩部定位器和前臂定位器测虽肱骨近端BMD.研究第一部分包括30名忐愿者,每人连续测量右侧肱骨近端BMD 2次,根据测量结果计算短期精密度RMS SD和RMS CV;第二部分包括92名志愿者,记录其年龄、身高、体重,测量右侧肱骨近端BMD,分析肱骨近端BMD与年龄和BMl的相关性.结果 本研究肱骨近端BMD测量方法的短期精密度:RMS SD=0.011 g/cm2,RMS CV=2.4%.本研究92名志愿者平均(60.2±6.4)岁,平均身高(159.5±5.4)cm,平均体质晕(59.4±7.5)kg,平均BMI 23.3±2.7,平均肱骨近端BMD(0.543±0.083)g/cm2,肱骨近端BMD 同年龄呈负相关,同BMI无显著相关.结论 本研究建立了一种测苗肱骨近端BMD的方法;年龄越人肱骨近端BMD越低;由于BMI对BMD的影响会掩盖骨质的丢失,而非负重区域即肱骨近端会最大程度地减少BMI对BMD的影响程度.
