目的:观察并探讨下肢深静脉血栓彩色超声影像的特点.方法:随机选取2014年10月—2017年2月我院接收的患有下肢深静脉血拴的病人70例进行研究,所有病人全都进行彩色超声检测,分析彩色超声影像检测结果.结果:彩色超声检测下肢深静脉血栓的准确度为90.55％;病人侧血管腔直径显著比健侧高,血流速度和健侧相比也较慢.结论:彩色超声对于检测下肢深静脉血拴几乎不会造成创伤,可以反复进行,检测准确度较高,可以随时了解血栓的状况,值得被较大范围应用.

目的:主要针对超声造影在子宫内膜癌与黏膜下肌瘤鉴别诊断中应用情况进行研究.方法:将造影剂灌注于患者患处,通过造影仪图像分析22名子宫内膜癌患者与30名黏膜下肌瘤患者患处组织特点.结果:子宫内膜癌患者患处组织当中的造影剂在出现时间(7.45±3.02)、达峰时间(15.49±5.68)、减退时间均比子宫内膜层用时少;黏膜下肌瘤患者患处瘤体结构中造影剂的出现时间(5.32±2.32)、达峰时间(15.49±5.68)比子宫基层用时少但也出现同步情况,子宫肌层的造影剂减退时间比瘤体患处减退速度慢.子宫内膜癌通过造影术检查报告中显示造影出现时间,强度曲线呈下降图像,强度值呈单项,黏膜下肌瘤则是呈双相模式.结论:超声造影术对鉴别子宫内膜癌和黏膜下肌瘤有着重要的参考价值.

目的:分析彩色多普勒超声诊断高血压性心脏病临床应用.方法:随机抽取70名在我院治疗高血压性心脏病患者作为研究对象,分成对照组和观察组两组,其中对照组35人,采用心电图行检查.观察组35人,采用彩色多普勒超声仪(心脏彩超)检查,分析两种检查方法对高血压性心脏病的检查结果.结果:观察组患者通过检查分析左心房内径、主动脉内径结果为(4.15mm±0.36mm)、(1.26±0.18),对照组患者通过检查分析左心房内径、主动脉内径结果为(3.25mm±0.32mm)、(1.21±0.12),观察组指标明显高于对照组.在左心室肥厚、左心房增大、主动脉扩张、主动脉弹性下降等心脏病类型检测率方面观察组高于对照组,两者对比具有统计学意义.结论:心脏彩超对高血压性心脏病检测具有:敏感性高、准确率高、检测方便快捷等优点,可以被医学界广泛应用.

近年来,超声造影医疗技术快速发展,被医学界广泛应用,超声造影技术对临床诊断起重要作用.尤其是对妇科疾病,大部分妇科疾病患者病原体出现在子宫,难以诊断疾病类型.通过造影剂介入患者体内方式,可以通过检测仪显示的图像对患者子宫情况进行绘制,从而掌握患者子宫具体情况,使医生可以准确鉴别患者疾病情况.现阶段,主要是通过将造影剂灌注于患者子宫或者其输卵管对患者病情进行观察、鉴别.

Objective It is to approach the correlation of ultrasonographic grading of varicocele(VC) with the changes of the concentration of nitric oxide(NO) and α-glycosidase(NAG) in semen after varicocelectomy.Methods 150 patients with VC were diagnosed by color doppler ultrasonography(CDU) and graded into 3 groups as VCI,VCII and VCIII,according to three different grading indexes the regurgitant volume of pampiniform plexus veins(PPV),the maximum diameter of PPV and the combination of the regurgitant volume and the maximum diameter of PPV.All patients were underwent high ligation of the spermatic vein.And the concentration of NO and the activity of NAG in semen were detected before and after varicocelectomy according to the WHO guidelines.Results With the maximum diameter of PPV as the grading index,there were significant differences in the seminal NO and NAG of VCII and VCIII(P<0.05),but not of VCI(P>0.05) before and after varicocelectomy,while based on the regurgitant volume of PPV or the combination of the regurgitant volume and the maximum diameter of PPV,there were insignificant differences in VCI(P>0.05),but there was no significant difference in VCⅡ and VCⅢ(P<0.05).Conclusion Different grading indexes influence the changes of the concentration of NO and activity of NAG in semen before and after varicocelectomy.Different grades of VC respond differently to varicocelectomy.Whether VCI necessitate varicocelectomy needs to be further investigated.

Objective It is to study the correlation of testicular microlithiasis(TM) with the change content of nitric oxide and α-glycosidase(NAG) in semen in patients with infertility.Methods 59 patients with testicular microlithiasis were found by high-frequency ultrasound and the content of nitric oxide and α-glycosidase in semen in these patients were measured.Results 43 patients of testicular microlithiasis were found in two sides and 16 patients were found in one side,including 43 varicocele,6 cryptorchidism,4 testicular hydrocele and 6 testicular.Class testicular microlithiasis(CTM)in 25(42%)cases and limited testicular microlithiasis(LTM)in 34(58%)cases.NO,NAG in semen and bilateral testicular peak systolic velocity(PSV) had significantly differences in CTM(P<0.05).No significantly differences was found in LTM and normal.No significantly differences were observed in the age of onset,bilateral testicular volume,resistance index(RI)of bilateral testicular arteries.Conclusion The sonographic appearance of TM is conductive to the definite diagnosis of the disease.TM is correlated with NO and NAG in semen criterion,but 73% patients have VC,mechanism study is further need.
