Objective To evaluate different angiocardiographic techniques of congenital heart disease in children. Methods 11045 pediatric patients with congenital heart disease were performed angiocardiography using cut film, cine film and digital subtraction angiography(DSA) equipments. Different angiocardiographic techniques were used. Results The diagnostic accuracy of cut film with conventional AP and lateral views was 80.5%,the diagnostic accuracy of cine film with angulated views was 90.0% and the diagnostic accuracy of DSA using non-ionic contrast medium with angulated views was 96.5%. Conclusion Dynamic picture angiography with digital subtraction using non-ionic contrast medium under rapid injection is the key for claiming the high quality imaging diaguosis of congenital heart disease in children.

Objective:The occurrence of numerous tumors, particularly classical Hodgkin's lymphoma (CHL), is related with Ep-stein-Barr virus (EBV) infection. However, the incidence of CHL and its association with EBV varies significantly with ethnicity, geo-graphic location, sex, and age. This study investigated the association of EBV infection with CHL in Northern Chinese Han population. Methods:EBV-encoded small RNA (EBER) was detected in 136 cases of CHL through in situ hybridization. Results:A total of 37 cas-es were EBER positive (28%). The mixed cellularity (MC) subtype had the highest positive EBER rate of 49%(23/47;P<0.001), fol-lowed by lymphocyte-rich subtype with 30%(3/10), nodular sclerosis (NS) subtype with 14%(10/73), and 1ymphocyte depletion with 0%(0/2). Our study identified a single age distribution in the third decade. Moreover, NS subtype showed an evident single peak in the third decade. However, MC subtype had a lower peak in the fifth decade. The incidence of EBER showed a bimodal age distribution with two peaks in the first and fifth decades (21.6%and 24.3%, respectively). Conclusion:CHL in Northern Chinese Han population was associated with EBV infection, particularly the MC subtype.

Objective To investigate the prevalence of nutritional risk and malnutrition,and the application of nutrition support in hospitalized patients with surgically treated gynecologic malignant tumors.Methods 237 hospitalized patients with malignant tumors receiving surgery in Department of Gynecology of Beijing Hospital from January 1 to December 31,2013 were continuously sampled.Nutritional Risk Screening 2002 (NRS 2002) was performed in the morning the day after admission.NRS 2002 score ≥ 3 was considered indicating nutritional risk.Malnutrition was judged in accordance with NRS 2002.The application of postoperative nutrition support was recorded.Results The nutritional risk screening was applicable in all the patients (100％).The prevalence of malnutrition was 5.1％ (12/237) in the whole study population,9.2％ in the elderly (≥65 years),significantly higher than that in the patients ＜ 65 years (2.7％) (P =0.034).The nutritional risk rate was 21.1％ (50/237),which was 29.9％ in the patients ≥ 65 years and significantly lower in the patients ＜ 65 years (16.0％) (P =0.014).The nutritional risk rate in the patients with ovarian and endometrial cancers was higher the rate in those patients with vaginal and vulvar cancer was lower.47 patients (19.8％)received postoperative nutrition support,all being parenteral nutrition,including total parenteral nutrition in 13 patients (5.5％) and single transfusion (providing two or more than two amongs glucose,fat emulsion,andi amino acids) in 34 (14.3％).Tube feeding was not applied in all the patients.33 cases (66％) in the 50 patients with nutritional risk were supported by parenteral nutrition,while 14 cases (7.5％) in the 187 patients without nutritional risk were supported by parenteral nutrition.Conclusions There is nutritional risk in the patients with gynecology malignant tumors,the rate of which is higher in elderly patents (≥ 65 years) than in the patients of other age groups.Therefore,attention must be paid to ensure adequate postoperative nutrition support in the elderly patients.
