AT2受体诱导新生大鼠肾小管上皮细胞凋亡的研究

目的探讨AT2受体在诱导肾小管上皮细胞凋亡中的作用.方法通过取新生大鼠肾小管上皮细胞体外培养,传代后加入不同浓度的AT2受体兴奋剂CGP-42112A,在不同时间用流式细胞仪测定凋亡细胞比值,并结合TUNEL分析.结果CGP-42112A不同浓度加入细胞24h后,随着剂量的增大,凋亡细胞所占比值逐渐增加,与对照组比较均具有显著差异,P＜0.001.10-5M CGP-42112A作用于细胞,随着时间的延长,凋亡细胞所占比值逐渐增加,与对照组比较有显著差异,P＜0.001.结论AT2受体可诱导新生大鼠肾小管上皮细胞凋亡,凋亡细胞数与受体剂量正相关,与受体兴奋剂作用时间正相关.     

全髋关节置换术治疗强直性脊柱炎致髋关节强直的疗效及康复锻炼的意义

Objective To investigate the clinical effects of total hip arthroplasty (THA) for bony ankylosis in patients with ankylosing spondylitis and the significance of postoperative rehabilitation. Meth-ods From October 1998 to May 2007, 28 patients (46 hips) suffered from ankylosing spondylitis with hip bony ankylosis underwent THA. There were 27 males, 1 female, with the mean age of 38.9 years (range 22 to 58 years). Posterior lateral hip incision was performed in 34 hips, and modified anterior lateral combined with lateral hip incision in 12 hips. Forty hips applied cementless THA and 6 hips applied mixed THA. Har-ris scores, VAS scores and total hip range of motion in all patients were compared pre-and postoperatively to evaluate the clinical effects. Results All patients were followed up from 10 months to 64 months, with the mean time of 38.2 months. No paralysis, decubitus, and lung infection were found. Joint dislocation hap-pened in 1 case 2 weeks after operation, and was cured with close reduction. Heterotopic bone formation with Brooker Ⅰ was found in 6 hips and Brooker Ⅱ in 2 hips. Harris score increased from 28.3±10.3 preop-eratively to 82.7±7.6 postoperatively. VAS score changed from 3.5±1.4 preoperatively to 3.8±1.8 postopera-tively, and no significance was found. The hip movement range increased from 15.6°±9.3° preoperatively to 133.7°±17.6° postoperatively. Bony ankylosis in all patients disappeared and the hip function improved sig-nificantly after operation. Conclusion THA is the optimal method to treat the ankylosing spondylitis with hip bony ankylosis. Early rehabilitation is necessary to improve hip function.     

肌钙蛋白I在诊断急性心肌梗塞即时检测的意义

急性心肌梗塞（AMI）是临床急诊常见的急性多发病，正确诊断及时救治对挽救濒死心肌、改善预后、降低急性期病死率和死亡率具有重要意义。在AMI的生化诊断方面，肌酸激酶（CK）及其同工酶（CK—MB）是目前常用的指标，但是CK—MB并非心脏所特有，在正常人骨骼中也有少量存在。非心脏手术或骨骼肌损伤患常有CK—MB增高，因而临床应用受到限制。     

超声心动图对心肌梗死范围诊断与心电图诊断的对比

目的:为了更准确地定位心肌梗死,为临床提供可靠的治疗依据。方法:对90例患者心电图(ECG)定位与超声心动图的定位进行比较。结果:两者可以相互验证。ECG所示梗死部位与超声心动图出现运动前的室壁节段大致相同,符合率78.9%,其中后壁心肌梗死21例,前间壁心肌梗死30例,广泛前壁心肌梗死16例。结论:超声心动图对心肌梗死诊断高于心电图对心肌梗死的诊断,并且可以弥补心电图对心肌梗死诊断的不足。     

启发式教学在生理学教学中的应用研究

针对生理学课程理论抽象、实验操作复杂等特点,阐述了启发式教学方法取代传统填鸭式教学方法的必然性。因生理学教学难度大、实验操作条件高,故着重介绍了问答式、讨论式、演绎式、归纳式、直观式等五种启发式教学方法在生理学教学中的应用。     

介绍两则组织切片染色小技巧

在常规染色和特殊染色的操作过程中，由于日工作量的巨大．切片染色的种类繁多。常常会使切片或染色剂出现一系列意想不到的问题．如：经典的教学HE切片褪色；短期内特染所用的无色品红液失效等系列问题一直困扰着我们，根据我科多年来积累的经验．现将介绍一种HE切片褪色、无色品红液在短期内失效的补救方法。以供大家参考。     

项灵汤治疗气滞血瘀型颈椎病的作用

应用经验方项灵汤治疗60例气滞血瘀型颈椎病患，并设60例西药治疗对照组。对比两组治疗前后纤维蛋白原(Fg)和超氧化物歧化酶(SOD)的改变情况。结果显示中药治疗组较西药治疗组有更好的治疗效果，能更明显降低血液黏稠度，抑制体内过氧化物生成，从而达到行气活血的目的。
