The practical course of medical English for academic purpose is the academic module of medical English teaching system. Based on the target situation analysis, the course consists of reading and writing of scientific papers, design of academic posters, and oral presentation in academic conferences, all of which focus on the selected key literature. During the course, the genre analysis theory, task-based teaching and situational teaching were applied to help students to improve their practical competence of academic English through accomplishing different kinds of academic communicative activities.

Textbook construction is an important part of building TCM English teaching system and its key research point is summarizing and exploring the basic principles and laws for guiding the compilation practice. This article tried to apply the theory of English for Specific Purpose and combine the compilation practice of English for TCM to explore the particular principles for compiling TCM English textbook.

OBJECTIVE: To explore the characteristics of the sublingual venae in patients with primary liver cancer (PLC). METHODS: The shape, color and the red, green and blue values of the sublingual venae were analyzed quantitatively for PLC patients in different clinical stages by analysis system for comprehensive information of tongue diagnosis. RESULTS: With the aggravating of the disease, the patients' sublingual venae became wide and tortuous, and their color became blue and purple. The abnormality of the sublingual venae was more serious in clinical stage III than in stages I and II (P < 0.05). CONCLUSION: The shape, color and abnormality degree of the sublingual venae in patients with PLC in different clinical stages are distinct.

OBJECTIVE: To explore the characteristics of tongue color in patients with primary liver cancer (PLC). METHODS: Tongue color and its RGB value were analyzed quantitatively for PLC patients in different clinical periods and other cancer patients by analysis system for comprehensive information of tongue diagnosis. RESULTS: The rate of blue and purple tongue was higher (P<0.05) and all the values of RGB were lower (P<0.01) in PLC patients compared with other cancer patients. In different clinical periods, the rate of blue and purple tongue in stage III was the highest (P<0.05). CONCLUSION: The blue and purple tongue is one of the most important tongue characteristics of PLC patients.

OBJECTIVE: To find out some microscopically visible morphological differences in normal tongue manifestation between patients with primary liver cancer and healthy adults, and provide some beneficial evidences for microcosmic syndrome differentiation of tongue inspection. METHODS: Microcirculations of the tongue tip, which represented the macroscopical normal tongue manifestation, were observed under an optical microscope in patients with primary liver cancer and healthy adults. Exfoliated cells from tongue coating were examined by hematoxylin-eosin staining. RESULTS: The proportion of normal tongue manifestation was larger in healthy adults (38.89%) than that in patients with primary liver cancer (2.32%). The total score of microcirculation of tongue tip and the maturation index of exfoliated cells from tongue coating were both higher in patients with primary liver cancer than those in healthy adults with normal tongue manifestation (P<0.01, P<0.05). CONCLUSION: Normal tongue manifestation, which is macroscopically visible, can be observed in both patients with primary liver cancer and healthy adults, but there exists obvious difference in microcosmic view.

Objective To evaluate the effect of anticoagulant therapy by pulmonary ventilation/perfusion (V/Q) imaging in chronic thromboembolic pulmonary hypertension (CTEPH) patients.Methods Thirtysix CTEPH patients (16 males,20 females,average age:(53.8±13.8) years) diagnosed by pulmonary angiography from January 2013 to December 2015 were included in this retrospective study.All patients received anticoagulant therapy for more than 6 months.They underwent pulmonary V/Q imaging before and 6 months after anticoagulant therapy.The numbers of pulmonary segments with perfusion defect,percentage of perfusion defect score (PPDs) and pulmonary arterial systolic pressure (PASP) before and after anticoagulant therapy were measured by echocardiography.Pair t test was used for data analysis.Results Before anticoagulant therapy,there were 319 pulmonary segments with perfusion defect in 36 CTEPH patients,8.9± 3.4 on average,and reduced to 8.4+3.6 after anticoagulant therapy (t =3.101,P＜0.01).The PPDs before and after anticoagulant therapy were (43.3±19.7)％ and (40.8±+20.5)％ (t=2.364,P＜0.05).In the subgroup of 9 patients with improved pulmonary perfusion,the PASP significantly decreased from (68.7±27.3)to (56.1 +±34.8) mmHg (1 mm Hg =0.133 kPa;t =2.465,P＜ 0.05) after anticoagulant therapy.In contrast,in the subgroup of 27 patients with no improved pulmonary perfusion,the PASP before and after anticoagulant therapy were (71.3±26.9) and (76.7±35.0) mmHg respectively (t=-1.511,P＞0.05).Conclusion Pulmonary V/Q imaging is a reliable method for evaluating the changes of pulmonary perfusion before and after anticoagulant therapy,and it is valuable for assessing the effect of anticoagulant therapy in CTEPH patients.
