超声心动图诊断原发性心脏肿瘤

目的：探讨原发性心脏肿瘤超声心动图(ECG)特征。方法：利用ECG检查42例心脏肿瘤。其中粘液瘤38例，恶性肉瘤2例，均经手术病理证实。横纹肌瘤2例，经随访证实。结果：ECG对38例粘液瘤，2例横纹肌瘤全部做出正确诊断。2例恶性肿瘤提示相应部位占位病变。粘液瘤多发生在左房，有明确的瘤蒂，肿瘤回声稀疏，活动度大。恶性肿瘤回声较强、无蒂，活动度小。横纹肌瘤多发生在室壁心肌内，呈结节状，与正常心肌间有明确的界限。结论：ECG对原发心脏肿瘤的诊断具有重要意义，可初步区分良、恶性肿瘤。     

RETINOBLASTOMALACTIC DEHYDROGENASE OF AQUEOUS HUMOUR AND ITS ISOENZYMES

Lactic dehydrogenase (LDH) activity in aqueoushumour and serum was measured of 24 patients withretinoblastoma, senile cataract, glaucoma, and cho-roid melanoma in addition to LDH isoenzyme fractions. The results were compared with those of the20 normal children. The ratio of aqueous humourLDH to serum LDH was 4.32+2.80, and that ofisoenzymes LDH4 to LDHl was greater than l. Theresults of our study suggested that the total LDHactivity and isoenzyme fractions in the aqueoushumour is of value in the diagnosis of retinobla&toma.     

活动翼矫治器的研制与初步应用

目的评价活动翼矫治器的设计原理与矫治效能。方法应用活动翼矫治器对588例错畸形病例进行矫治。对2001年～2004年的389例进行研究,分析其疗效、疗程、复诊次数、弓丝使用等情况。结果病例完成时间为4～15个月,平均为8.13个月。复诊次数4～13次,平均7.55次。平均每例上颌使用弓丝1.95根、下颌1.98根。仅11例病例使用口外支抗。结论活动翼矫治器是一种新研发的高效能矫治器,能够明显缩短疗程、减少复诊次数、减少弓丝用量

乳腺三角瓣交叉支撑法矫治乳头内陷

目的介绍一种矫治乳头内陷的新方法。方法采用乳头基底部乳腺组织三角瓣,交叉缝合支撑乳头基底,防止乳头内陷,保持乳头外凸形态。结果应用本方法矫治乳头内陷13例24侧,效果满意。随访2~8个月,乳头功能正常,外形、高度均理想,无回缩。结论本方法简单安全,效果持久,均能获得满意的效果。     

TNF-α、IL-6与进展期结直肠癌低白蛋白血症的相关性研究

目的:探讨进展期结直肠癌患者血清肿瘤坏死因子(TNF-α)、白细胞介素-6(IL-6)与并发低白蛋白血症的关系. 方法:根据血清白蛋白(albumin,Alb)值将59例进展期结直肠癌患者分两组:伴低白蛋白血症(Alb≤35 g/L)组35例和白蛋白正常组(Alb＞35 g/L)患者24例,并以15例健康体检者作为正常对照组,应用双抗体夹心酶联免疫吸附法(ELISA)定量测定各组血清TNF-α、IL-6水平.结果:①病例组患者血清TNF-α和IL-6水平明显高于正常对照组(P=0.001,P=0.034);②肿瘤病例中,低白蛋白血症组血清TNF-α、IL-6水平明显高于白蛋白正常组(P=0.000,P=0.002);③病例组血清Alb与TNF-α、IL-6浓度均呈显著负相关(Alb与TNF-α:r=-0.606,P=0.000;Alb与IL-6:r=-0.439,P=0.001).结论:进展期结直肠癌患者并发低白蛋白血症与血清TNF-α、IL-6浓度的升高相关.     

微创经皮锁定加压钢板内固定治疗胫骨远端骨折

目的探讨微创经皮锁定加压钢板内固定治疗胫骨远端骨折的效果。方法自2003年6月～2005年5月微创经皮锁定加压钢板内固定治疗胫骨远端骨折56例。按AO分类标准:A型20例,B型19例,C型17例。结果48例获得随访,平均11个月(8～21个月)。X线片显示骨折全部一期愈合,平均愈合时间为13周,均无感染、骨不连、钢板松动等并发症。按照Mazur踝关节功能评分:优38例,良6例,可4例,优良率为91.7%。结论微创经皮锁定加压钢板内固定治疗胫骨远端骨折符合生物力学固定(BO)原则,内固定牢靠,有利于骨折的愈合及软组织的修复。     

Comparison of clinical outcomes of frozen-thawed blastocysts transfer in natural and hormonally controlled cycles

Objectives:To assess the clinical outcomes of frozen-thawed blastocysts transfer in natural and hormonally controlled cycles.Methods:A retrospective analysis of natural and hormonally controlled cycle for 246 frozen-thawed blastocyst transfer cycles,the clinical pregnancy rate,implantation rate,early abortion rate were compared.Results:Of the 192 hormonally controlled cycles,the cancel rate,clinical pregnancy rate per ET,implantation rate and abortion rate were 7.3%(14/192),53.9%(96/178),38.8%(131/338)and 11.5%(11/96)respectively,whereas in 54 natural cycles,these rates were 16.7%(9/54),68.9%(31/45),52.9%(45/85)and 16.1%(5/31)respectively.There was no significant difference between the two groups with regard to the clinical pregnancy and abortion rate per ET,but the cancel rate and implantation rate were higher in natural cycles.However,the pregnancy and implantation rates of patients without PCOS in hormonal control cycles(57.2%,40.9%)were similar with those in natural cycles(P>0.05).Conclusion:These findings suggested that both hormonally controlled and natural cycles had similar pregnancy outcomes in frozen-thawed blastocysts transfer.
