We have made a cheap microsystem of capillary electrophoresis with a new method, integrating the electrodes, injection channel, separation channel, buffer reservoirs and detection cell on a polymethylmethacrylate (PMMA) chip. Using an integrated micro carbon fiber disk electrode as the working electrode in three electrodes system, 1 × 10-4 mol/L dopamine (DA) could be detected with end-column amperometric detection. The reproducibility was good. Peak current was 6.73 nA、theoretical plate numher was 71300/m and height equivalent of one theoretical plate height was 14.0 μm for 1 × 10-4 mol/L DA. The limit of detection was 3.6× 10-8mol/L and the linear range was extended from 5 × 10-7 mol/L to 1 × 10-4 mol/L for DA. 1 × 10-4 mol/L catechol (CA) and 5× 10- 5 mol/L DA were also separated completely with R. = 10.1.

An online questionnaire to 103 professionals of traditional Chinese medicine (TCM) was conducted to acquire their recognition and understanding of international communicative competence. The results showed that foreign language communicative competence and solid medical knowledge are considered the most important qualities while the importance of global vision, strategic thinking, cross-cultural awareness/sensitivity and communicative strategy is comparatively underestimated. It was proposed that domestic TCM universities and colleges strive to improve the soft skills for TCM professionals and cultivate more interdisciplinary TCM talents armed with professional expertise, foreign language communicative competence as well as international and multicultural awareness.

International communication capabilities of traditional Chinese medicine professionals are closely related to the publicity of Chinese medical culture and know-how.Based on the interview results as well as literature research,this paper discusses the qualification of traditional Chinese medicine professionals and proposes five essential elements constituting their international communication capabilities:knowledge and skills of Chinese medicine,foreign language proficiency,knowledge and skills of international communication,a global perspective as well as personal traits.It is expected that it may contribute to the syllabus design,in-service training and talents cultivation in Chinese medical colleges and universities.

Objective To evaluate the feasibility and efficacy of preoperative sequential transcatheter arterial chemoembolization (TACE) followed by selective portal venous embolization (PVE) in patients with marginally resectable hepatocellular carcinoma (HCC).The aim was to find out whether this combined procedure helped to increase the rate of extended radical liver resection.Methods From March 2009 to November 2016,29 patients with HCC which were marginally resectable underwent preoperative TACE combined with PVE were included into this study.All these patients were subsequently assessed to undergo radical hepatectomy.The complications,laboratory results,volume changes of each liver lobe and patient survival were analyzed.Results TACE combined with PVE was successful in all the 29 patients.There were no major complications.After the procedure,the volumes of the tumor and the part of the liver to be resected decreased to certain degree.The remnant liver volume (RLV) increased remarkably.The RLV were (395.4 ±58.7) cm3 and (599.2 ±75.2) cm3 before and after the procedure,respectively.The difference was significant (P ＜ 0.05).19 patients underwent radical hemihepatectomy or trisectionectomy,with a resection rate of 65.5％ (19/29).There were sufficient surgical margins in all the resected tumors.After operation,the 1-,3-,and 5-year survival rates were 58.8％,35.5％ and 17.6％,respectively.Conclusion For HCC patients who had marginally resectable HCC,preoperative TACE combined with PVE efficiently controlled the growth of the tumors,decreased the volume of the liver lobe with tumor,increased the RLV,and made it possible for a planned two-stage radical hepatectomy with sufficient surgical margin and better survival in a significant proportion of patients.
