Objective To evaluate the features of the encapsulated papillary thyroid carcinoma (EPTC) by ultrasound and histopathology.Methods The EPTC were classified into the following two types based on the shape,characteristics of the border,size of the nodule,echogenicity,a hypoechoic halo and microcalcification by ultrasound features:papillary carcinoma (PC) type and follicular tumor (FT) type.Results Of all the 33 cases,21 cases were PC type and 12 cases were FT type.The histopathological result of PC type was papillary carcinoma.PC type had a jagged border,an irregular tumor shape with marked hypoechogenicity by ultrasound.PC type were composed of papillae by histopathology,completely surrounded by a fibrous capsule with tumor cells having the nuclear features of papillary thyroid carcinoma,densely interstitial fibrosis and microcalcification;FT type had a smooth border,a regular shape (spherical to oval),isoechogenicity and a hypoechoic halo by ultrasound.FT type were completely or significantly composed of follicles by histopathology,completely surrounded by a fibrous capsule with tumor cells having the nuclear features of papillary thyroid carcinoma.Hypoechoic halo were more frequently observed in FT type than in PC type.The nodule size of FT type(1.8-7.0 cm)was larger than that of PC type(0.8-5.2 cm).Fine and multiple strong echoes were characteristically present only in PC type.Conclusion The EPTC have characteristic features that are similar to those of the benign follicular thyroid tumor by ultrasound.

Objective To investigate the clinical features and prognostic factors in children with idi-opathic pulmonary arterial hypertension(IPAH). Methods The data of children with IPAH diagnosed in Beijing Children′s Hospital from January 2006 to December 2015 were collected. The cases were divided into survival group and death group according to the prognosis. The risk factors influencing prognosis in children with IPAH were identified by Logistic regression analysis. Results Total 26 patients were enrolled in this study,and 17 of them survived and 9 of them were dead. IPAH was found to be more common in school-age children. The average age of the patients was(6. 6 ± 3. 6)years and the male to female ratio was 1. 17∶1. All of the children had the symptoms with decreased activity tolerance and fatigue. The incidence of syncope and dyspnea and edema of lower extremity were 34. 6%,23. 1%. Accentuated pulmonic second sound(P2) was detected in 92. 3% of patients during physical examination, which was also the most common sign. About 50. 0% patients were functional class Ⅲ-Ⅳ. Echocardiography showed that all childrens′ mean pulmonary artery systolic pressure(PASP) was(79. 0 ± 20. 3) mmHg(1 mmHg=0. 133 kPa) and 16 of them with right ventricular dilatation. Electrocardiogram with ST-T changes and right ventricular high voltage were common. The average plasma level of brain natriuretic peptide(BNP) in all cases was(870. 4 ± 720. 9) pg/ml. The single factor analysis illustrated that syncope(OR=26. 25,95%CI 3. 04 -226. 60,P=0. 003),heart func-tional class Ⅲ-Ⅳ(OR=19. 199,95%CI 1. 88 -196. 53, P=0. 0128), PASP≥70 mmHg(OR =9. 936, 95%CI 1. 81-∞,P=0. 005),BNP≥850 pg/ml(OR=59. 991,95%CI 4. 69-767. 62,P=0. 002) indica-ted the worse outcome. Conclusion IPAH in children is rare and the prognosis is poor. Syncope, cardiac function grade,PASP and the levels of BNP are the main important factors affecting the prognosis of children with IPAH. BNP has important clinical significance for the evaluation of IPAH and the prognosis of the disease.

Objective To observe the clinical characteristics and prognosis in children with high take -off coronary artery.Methods The clinical characteristics,laboratory examinations and prognosis were retrospectively ana-lyzed in 49 children with high take -off coronary artery who had been admitted to Beijing Children′s Hospital Affiliated to Capital Medical University from April 2009 to December 201 2.Results Among 49 medical records of children with high take -off coronary artery,34 cases were male and 1 5 cases were female,with a mean age of (9.28 ±4.42)years old,and the youngest patient was 1 3 months old,and the oldest patient was 1 7 years and 2 months old.The 64 -section multidetector CT angiography of all patients showed one or both coronary arteries originated from 1 .0 cm higher than the junction area of sinus and aorta,including 38 high take -off of the left coronary artery,7 high take -off of the right coronary artery and 4 high take -off of both coronary arteries.The chief complaints of the patients included chest pain (22 cases,44.90%),chest tightness(1 3 cases,26.53%),declining of exercise tolerance(7 cases,1 4.29%),fatigue (5 cases,1 0.20%),palpitation(3 cases,6.21 %),syncope(1 case,2.04%).Electrocardiogram(ECG)of those pa-tients showed ST -T changes,atrioventricular block,sinus tachycardia,pathological Q -wave,proiosystole and bundle branch block.Ultrasonic cardiogram(UCG)indicated 1 4 patients with the enlarged left ventricle,including 2 patients with ejection fraction lower than 60%.After 1 0 days hospitalization,the anesis of chest pain and chest tightness were significantly different statistically(P <0.05),but there was no significant difference in ECG and UCG.Thirty -nine out of 49 children were followed for 1 year.After 3 months,6 patients with ST -T problem showed normal ST -T segment. After 6 months,1 0 patients with ST -T problem showed normal ST -T segment.After 1 year,1 7 patients with ST -T problem showed normal ST -T segment.Conclusions High take -off coronary artery is a rare malformation of the coronary artery,which can cause myocardial ischemic,leading to multiple clinical manifestations and may result in ECG changes and the left ventricle enlargement.High take -off coronary artery can be confused with myocarditis and myocar-dial lesion clinically.Patients receiving systemic treatment may have their symptoms released,but ECG and UCG may not relieve in a short term.Patients with high take -off coronary artery need long -term observation.

Objective To observe the therapeutic effect of Lai's acupuncture therapy combined with Chinese herbal decoction for the treatment of infertility with ovulatory dysfunction, and to summarize the experience of Professor Lai Xin-Sheng in treating infertility. Methods Ninety-six infertility patients with ovulatory dysfunction were randomized into treatment group and control group, 48 cases in each group. The treatment group was treated with Lai's Tongyuan acupuncture therapy for regulating Governor Vessel to tranquilize mind, inducing meridian Qi to original Qi, and was also given oral use of Chinese herbal decoction of Lai's Yiyun Recipe for promoting gestation. The control group was treated with Chinese herbal decoction alone. The treatment began exactly after the completion of menstruation period and lasted 15 days for one treatment course, covering 3 courses. And then the patients of the two groups were followed-up for 3 months. Therapeutic effect and pregnancy rate were evaluated after treatment, serum levels of estradiol and progesterone were examined, and abdominal ultrasonography was used for monitoring the maximum diameter of the dominant follicles and endometrial thickness before and after treatment. Results (1) Three cases from the treatment group and 5 cases from the control group were dropped out, and the final case number in the treatment group and control group was 45, 43 respectively. (2) The total efficiency of the treatment group was 88.9％, and that of the control group was 81.4％. The effect of the treatment group was better than that of the control group (P < 0.05). (3) The pregnancy rate of the treatment group was 73.3％, higher than that of the control group (51.2％), the difference being significant (P < 0.05). (4) After treatment, the maximum diameter of the dominant follicles and endometrial thickness in the two groups were obviously improved(P < 0.05 compared with those before treatment), and the improvement in the treatment group was superior to that in the control group (P < 0.05). (5) After treatment, the serum levels of estradiol and progesterone in the two groups were obviously improved(P < 0.05 compared with those before treatment) , and the improvement in the treatment group was superior to that in the control group(P < 0.05). Conclusion The therapeutic effect of Lai's acupuncture therapy combined with Chinese herbal decoction is superior to that of Chinese herbal decoction alone, showing an obvious synergistic effect by shortening the course of treatment and enhancing pregnancy rate.
