Portal hypertension is a major complication of cirrhosis. The current gold standard for diagnosis is the hepatic venous pressure gradient, but it possesses limitations such as invasiveness. In recent years, non-invasive tests have made significant progress in terms of evaluating and prognostication of portal hypertension. This article reviews the diagnostic value and related research advancements of different non-invasive tests in assessing portal hypertension in patients with cirrhosis.

During the epidemic of COVID-19, The Fifth Hospital of Harbin Medical University organized and operated online blended teaching based on BOPPPS teaching mode. Before the opening of the school, the college concentrated on theoretical learning and online practice in BOPPPS teaching mode to ensure that teachers mastered online teaching methods before teaching. In the course of teaching, various means were used to strengthen the application of six modules in BOPPPS teaching mode. A multilevel online teaching supervision and feedback mechanism for colleges, teaching and research sections, teachers and students, and continuously improve the quality of teaching. The teaching practice of the first four weeks have shown that through the unified organization and implementation of the college, online teaching based on BOPPPS teaching mode can be realized efficiently, student-centered and participatory learning can be realized, and the online teaching ability of teachers can also be improved with satisfactory results.

Pulmonary hypertension (PAH) is a common pathological stats disease in clinic, it has a high morbidity and mortality.It was found that abnormal of endothelial growth factor, coagulation-related factors, 5-hydroxytryptamine, interleukin-6 and other inflammatory factors, hypoxia-inducible factors, transforming growth factor-β1 and connective tissue growth factor(CTGF) and so on were involved in the occurrence and development of PAH, but the specific mechanism was still unclear.In recent years, in monocrotaline(MCT) induced PAH rats model, they found that MCT rats had a significant higher concentration of mitochondrial coupling factor 6 (CF6) in both plasma and lung tissue than control group, which inhibited the activity of prostacyclin (PGI2), suggesting that CF6 may be involved in the occurrence and development of PAH.This paper will discuss the characteristics of CF6, the relationship between PGI2 and CF6, the relationship between PAH and CF6.
