住院病例抗菌药物临床应用情况分析

抗菌药物是临床应用最广泛的、同时也是滥用最严重的种类之一。抗菌药的不合理应用，是导致细菌耐药和住院费用居高不下的主要原因。参照卫生部新制订的《抗菌药物临床应用指导原则》，调查了解该院临床抗菌药物的使用情况，收集该院2005年2月全部出院病例共471份，对抗菌药物的使用情况进行统计分析。     

氧浓度对关节软骨细胞体外培养的影响

关节软骨在体内属缺氧组织,且组织内氧浓度水平呈现梯度,表现为软骨组织表层为10%,而至深层则下降到1%,因此采用空气中20%氧浓度对软骨细胞进行体外培养,显然不适宜。通过对关节软骨组织的生物学特性、生存环境以及不同氧浓度下软骨细胞体外培养的实验研究分析,认为5%氧浓度是体外培养关节软骨细胞的适宜浓度,同时在软骨细胞的不同生长时期对培养基氧浓度进行控制,可将软骨细胞处于较好的生长增殖状态。     

血液透析治疗重症急性胰腺炎21例疗效观察

重症急性胰腺炎(原称急性出血坏死性胰腺炎,现已弃用)是一个病情重、来势凶险、并发症多、死亡率高的消化系统重症,死亡率达40%~70%。近几年对它的认识和治疗有所提高,也涌现一些新的药物和治疗方法,死亡率下降致20%~40%。血液透析治疗方法就是一个疗效明显的、显著降低死亡率的、普遍被肯定的治疗方法。现将我们对血液透析治疗重症急性胰腺炎的总结和体会介绍如下。1资料与方法1.1一般资料收集本院2003年1月至2005年3月重症急性胰腺炎病例42例,男性22例,女性20例,年龄20~70岁,胆源性占50%,酒精源性占40.4%,不明原因占9.6%。将42例病人分成…     

Effect of Electromagnetic Fields on Proliferation and Differentiation of Cultured Mouse Bone Marrow Mesenchymal Stem Cells

Previous clinical observations and animal ex periments showed that EMFs could stimulate newbone formation of the fractures and increase thebone mineral density[1], but the manner in whichEMFs influence the behavior of bone remains poor ly understood. Recent studies[2] found that signaltransduction system plays an important role in thebiological effect of EMFs. Intracellular cAMP wasan important second messenger in signal transduc tion pathway. The cellular proliferation …     

放疗联合紫杉醇化疗治疗中晚期鼻咽癌的疗效观察

目的观察放疗联合紫杉醇治疗中晚期鼻咽癌患者的疗效。方法分析放疗联合紫杉醇治疗58例中晚期鼻咽癌的局控率、生存率和毒副反应,并与57例单纯放疗相比较。结果综合组和单放组的治疗有效率为87.9%、71.9%,颈部淋巴结有效率91.5%、75.4%,差异均有统计学意义(P<0.05)。综合组的远处转移率低于单放组(P<0.05)。两组1~3年生存率均无统计学意义(P>0.05)。综合组主要不良反应为白细胞下降、胃肠道反应等,经治疗可改善。结论放疗联合紫杉醇可提高中晚期鼻咽癌的近期疗效,毒副反应可耐受,长期疗效有待于临床进一步观察。     

Treatment of Thoracolumbar Vertebrate Fracture by Transpedicular Morselized Bone Grafting in Vertebrae for Spinal Fusion and Pedicle Screw Fixation

To enhance the fusion of graft bone in thoracolumbar vertebrae and minimize the postoperative loss of correction, short-segment pedicle screw fixation was reinforced with posterior moselizee bone grafting in vertebrae for spinal fusion in patients with thoracrolumbar vertebrate fractures. Seventy patients with thoracrolumbar vertebrate fractures were treated by short-segment pedicle screw fixation and were randomly divided into two groups. Fractures in group A （n=20） were rein-forced with posterior morselized bone grafting in vertebrae for spinal fusion, while patients group B （n=50） did not receive the morselized bone grafting for bone fusion. The two groups were compared in terms of kyphotic deformity, anterior vertebral height, instrument failure and neurological functions after the treatment. Frankel grading system was used for the evaluation of neurological evaluation and Denis scoring scale was employed for pain assessment. The results showed that the kyphosis correction was achieved in both group A and group B （group A： 6.4 degree; group B： 5.4 degree）/At the end of follow-up, kyphosis correction was maintained in group A but lost in group B （P=0.0001）. Postoperatively, greater anterior height was achieved in group A than in group B （P〈0.01）. During follow-up study, anterior vertebral height was maintained only in Group A （P〈0.001）. Both group A and group B showed good Denis pain scores （P1 and P2） but group A outdid group B in terms of control of severe and constant pain （P4 and P5）. By Frankel criteria, the changes in neurological functions in group A was better than those of group B （P〈0.001）. It is concluded that reinforcement of short-segment pedicle fixation with morselized bone grafting for the treatment of patients with thoracolumbar vertebrae fracture could achieve and maintain kyphosis correction, and it may also increase and maintain anterior vertebral height. Morselized bone grafting in vertebrae offers immediate spinal stability in patients with th

放射性核素显像在小儿下消化道出血诊断中的应用

应用99mTcO及99mTc-RBC动态显像诊断消化道出血20例，结果阳性18例（美克尔憩室11例，肠重复畸形5例，克隆氏病1例，溃疡性回肠炎1例均被手术证实），阴性2例（肠息肉2例，内窥镜证实）。认为此种检查操作简单，损伤小，安全，灵敏度高，可提示出血部位及原因，对诊断及治疗有极大帮助。
