Objective:To report the clinical features of pulmonary hypertension diagnosed by echocardiography in 5 patients with novel coronavirus pneumonia (COVID-19) in order to understand the special clinical manifestations of COVID-19 and explore the possible mechanism.Methods:The echocardiographic data and clinical characteristics of COVID-19 patients complicated with pulmonary hypertension diagnosed by echocardiography in Beijing Ditan Hospital, Capital Medical University were analyzed descriptively from February 5 to March 31, 2020.Results:A total of 15 patients with severe and critical COVID-19 patients underwent echocardiography. Of them, 7 patients were diagnosed with pulmonary hypertension, 5 of which were confirmed as complications of COVID-19. Among the 5 patients, 4 were female and 1 was male, aged 62-78 years; 4 were with hypertension, 3 were with diabetes, and 1 was with coronary atherosclerotic heart disease. All 5 critically ill patients with COVID-19 were given ventilator-assisted breathing, 2 of which were given extracorporeal membrane oxygenation at the same time. According to echocardiography, the systolic pressure of pulmonary artery in 5 patients was 43-65 mmHg, with an average of 54 mmHg. The severity of pulmonary hypertension was graded as mild in 1 patient and moderate in 4 patients. During the follow-up, pulmonary artery systolic pressure gradually decreased to normal in 4 patients, and then ventilator and ECMO were withdrawn; 1 patient died due to respiratory failure and persistent pulmonary hypertension.Conclusions:Patients with COVID-19 may be complicated by pulmonary hypertension, which is often found in the critical patients. Echocardiography is an important imagingdiagnostic method for pulmonary hypertension in patients with COVID-19.

目的:探讨速度向量成像技术(VVI)监测妊娠期肝内胆汁淤积症(ICP)孕妇胎儿左右心纵向整体心功能的临床价值.方法:以2016年11月至2017年11月,于首都医科大学附属北京地坛医院超声科检查发现的ICP胎儿为研究对象.母体血清总胆汁酸浓度10≤TBA＜ 40μmol/L为ICP轻度组,入组28例;TBA ≥40 μmol/L为ICP重度组,入组28例;选择同孕周的正常孕妇胎儿,为正常对照组,入组56例.对所有入组胎儿行超声心动图检查,留存动态四腔心声像图,将图像导入VVI处理软件脱机分析,获得左右心室VVI参数,包括收缩期峰值速度(Vs)、舒张期峰值速度(Vd)、收缩期峰值应变(S)、收缩期峰值应变率(SRs)、舒张期峰值应变率(SRd).结果:ICP重度组胎儿左心室整体SRs、SRd及S较ICP轻度组和对照组减低(P＜0.01),但左心室整体SRs、SRd及S于ICP轻度组和对照组间,差异无统计学意义(P ＞0.05);ICP重度组胎儿右室整体Vd较ICP轻度组、对照组减低(P＜0.01),但于ICP轻度组和对照组间,差异无统计学意义(P ＞0.05);ICP重度组胎儿右心室整体SRs、SRd及S较ICP轻度组和对照组减低(P＜0.01),但于ICP轻度组和对照组间,差异无统计学意义(P＞0.05).结论:母体重度胆汁酸增高损害胎儿左心及右心整体收缩及舒张功能;母体轻度胆汁酸增高对胎儿左右心整体心功能无明确影响.

Objective To evaluate the standard specification in liver biopsy guided by the color Doppler sonography through comparing the rate of complications between the two periods (January 2009 to March 2012 and April 2012 to June 2015).MethodsMedical records of all patients undergoing percutaneous liver biopsy guided by color Doppler sonography from January 2009 to June 2015 in Beijing Ditan Hospital, Capital Medical University were reviewed retrospectively. Patients were divided into treatment group (from April 2012 to June 2015) and control group (from January 2009 to March 2012) based on whether the standard specification was applied when patients undergoing liver biopsy guided by color Doppler sonography. The rates of complications were compared and further furtherly analyzed between the two groups.ResultsTotal of 5107 cases were given liver biopsy guided by the color Doppler sonography, among whom 2585 cases were in treatment group and 2522 cases were in control group. The total complication rate was 4.8 % (245/5107). In treatment group, bleeding was identiifed in 6 patients (0.23%), including one case (0.04%) with free intraperitoneal hemorrhage and 5 cases (0.19%) with subcapsular hematoma. Adjacent organ (kidney) injury was identiifed in 1 case (0.04%). Total of 86 patients (3.32%) occured the symptoms of pain. In control group, bleeding was identiifed in 22 cases (0.97%), including 2 cases (0.08%) with free hemorrhage, 18 cases (0.71%) with subcapsular hematoma, 1 case (0.04%) with hemobilia, 1 case (0.04%) with delayed bleeding and 130 patients (5.15%) occured the symptoms of pain. There were significant differences in complication rate (3.6% vs. 6.0%), bleeding rate (0.23% vs. 0.87%),incidence rate of hepatic capsular hematoma (0.19% vs. 0.71%) and rate of pain (3.32% vs. 5.15%) between treatment group and control group, respectively (P = 0.001, 0.002, 0.006, 0.001).ConclusionThe complication rate of liver biopsy guided by color Doppler sonography could be reduced by establishing reasonable standard speciifcation.

Objective To investigate the ultrasonographic appearance of alcohol-related pancreas injuries,and to provide reliable information for clinical diagnosis.Methods Ultrasund examination was performed on 480 patients of alcohol abuse,163 patients with pancreas injuries were divided into long-term alcohol abuse group(35 cases) and short-term alcohol abuse group(128 cases)according to alcohol abuse time,then the pancreas structure were analyzed.Ultrasonography was utilized to evaluate the effect on pancreas size,based on the factors of time period of intoxication,the age of the individuals and quantity of alcohol consumed.Results Pancreas size of long-term alcohol abuse group was smaller than that of short-term alcohol abuse group(t=13.572,P=0.000;t=-10.010,P=0.001;t=-10.700,P=0.001).Atrophy of pancreas,strengthened echo were correlated with the patient's age and length of time intoxicated(t=2.563,P=0.012;t=3.302,P=0.001).Conclusion Ultrasonography has important value in diagnosis of alcohol-related pancreas injuries,it can provide reliable information for clinical diagnosis.

Objective To evaluate the left ventricular function of patients with liver cirrhosis by tissue velocity imaging (TVI) and pulsed wave Doppler flow imaging (PW)with Tei index. Methods A total of 150 patients with liver cirrhosis and 180 patients with chronic hepatitis (control group) were enrolled in this study. Their LV Tei index was measured by TVI and PW. Results LV Tei index in liver cirrhosis group was higher than that in control group (P0. 01) , there was no significant difference of Tei index among the Child A and Child B liver cirrhosis patients and chronic hepatitis patients by TVI and PW( P0.05). There was significant difference of Tei index among Child C liver cirrhosis patients, Child A and Child B liver cirrhosis patients and chronic hepatitis patients (P0. 01). TVI showed there was significant difference of Tei index between child B liver cirrhosis patients and chronic hepatitis patients (P0.05) , while there was no significant difference by PW(P0. 05). When the patients with liver cirrhosis were classified according to abdominal dropsy, there was no significant difference of Tei index among the groups ( P0. 05). Conclusion The LV functions of patients with liver cirrhosis is abnormal, there is relations between the cardiac function of liver cirrhosis patients and the degrees of hepatic dysfunction, and no obvious correlation with abdominal dropsy. TVI can measure Tei index conveniently and sensitively.

Objective To investigate the ultrasound imaging characteristics of lymph node lesions in AIDS patients and the clinical application. Method A retrospective analysis of ultrasound imaging of 230 pathologically proved lymph node lesions in 77 patients was carried out. Results In 77 AIDS patients with lymph node lesions,lymph node tuberculosis was the most commonly prevalent,and fungal infection the second (penicilliosis marneffei was characteristic of AIDS); malignant lymphoma and Kaposi sar-coma were found in patients with tumors; many kinds of lymph node lesions were concurrent and easy to spread; the most common parts involved were cervix,abdomen,groin and armpit. Conclusion Ultrasound can be considered as the first imaging choice for the diagnosis and differential diagnosis of lymph node lesions in AIDS patients.
