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 study the relationships between neutralizing antibody response against autologous virus and disease progression of HIV-1 B'/C infected individuals in China.Methods:Twenty-four primary HIV-1 isolates were incubated with autologous plasma collected either freshly or at approximately six months intervals thereafter.Normal human peripheral blood mononuclear cells were incubated with the virus-serum mixtures for 7 days and then the production of p24 antigen was measured.The neutralizing titer of a particular plasma and virus was defined as the reciprocal of the highest dilution giving a 50% reduction in p24 Ag compared with NHP control wells.More than 1∶8 were considered significant and were scored as positive.Results:In neutralizing antibody(Nabs) response against contemporaneous virus,Nabs were produced in all slow progressors(SP) individuals,while only four in 21 of HIV group had.There was statistically significance of the neutralizing antibody titers between SP and HIV.When plasma samples of six months later were tested for their ability to neutralize autologous virus,all of SPs had higher neutralizing antibody titers and the titers of neutralizing antibody in HIV group had increased in different rate.Among the twenty-one individuals of HIV group,12 of these individuals had neutralizing antibody response against autologous virus and other 9 of these individuals had not.NAb titers of SP in six months later plasma were higher than those of HIV.There was a negative correlation between the generation of the neutralizing titer against autologous virus and the plasma HIV RNA level in HIV-1 B'/C infected individuals(including SP,HIV).Conclusion:Neutralizing antibody against autologous viruses in HIV-1 B'/C infected SP is higher than those of HIV group,suggesting that neutralizing antibodies play a vital role in delaying disease progression in these individuals.

Objective To study the amino acid mutations in neutralizing antibody 2F5 and 4E10 conserved epitopes ELDKWA and NWFDIT of HIV-1 membrane proximal external region(MPER)in 92 HIV-infected individuals and AIDS patients in China,and to provide a basis for the neutralizing antobodies immunotherapy and a design of vaccines. Methods Nest-PCR methods were used to amplity genes of the HIV-1 env gp41 region.The amplified fragments were sequenced by double-deoxygen terminal method and translated into amino acids for analysis.The mutations of 2F5 and 4E10 neutralizing epitopes were identified by comparison with the epitopes reference data in HIV-1 Sequence Database.Results There were mutations on both 2F5 and 4E10 neutralizing epitopes.2F5 conserved neutralizing epitopes major mutations tocused on E662A(14.1%),K665S(17.4%),A667K(16.3%),and 4E10 conserved neutralizing epltopes major mutations included N671S(13.0%),D674S(3.3%),T676S(16.3%).The mutation rates of 2F5 and 4E10 epitopes were significanfly different between CRF_B'C-clade and B'-clade(P<0.05).The mutata rates of CRF_B'C-clade were higher than that of CRFOI_AE-clade in 2F5 epitopes(P<0.05).The mutation rates of B'-clade in 4E10 eiptopes showed significant difference in slow progressors,HIV-infected individuals and AIDS patients,respectively(P<0.05).Conclusion The HIV-1 patients in China are demonstrated diversified mutations in 2F5 and 4E10 neutralizing epitopes.The mutation degrees of amlno acids in conserved neutralizing epitopes are different in different subtypes.There may be a correlation between neutralizing epitopes mutations of 4E10 with disease progression.

Objective To study the relationships between neutralizing antibody response against heterologous virus and disease progression in Chinese HIV-1 B'/C infected individuals. Methods Plasmas from HIV-1-infected individuals, grouped as HIV chronically infected or AIDS according to CD4+ count and clinical symptom, were tested for neutralizing activity against the three HIV-1 isolates with very low homology in vitro. Six two-fold dilutions of each plasma sample (from 1/10 to 1/320) were tested against each virus from the panel. Giving a 50% reduction in p24Ag compared with normal human plasma control wells was defined as positive. The breadth of the cross-neutralizing response was defined based on the number of viruses that were effectively neutralized by any given patient-derived plasma sample. The magnitude of the crossneutralizing response was defined based on the average neutralizing titer against all heterologous viruses. Resuits We found that there revealed a significant difference between HIV chronically infected and AIDS group in the breaths and magnitudes of neutralizing heterologous virus. There was higher prevalence for the frequency of neutralizing heterologous virus in HIV chronically infected than AIDS. The results showed that there was positive correlation between the breadths and magnitudes of neutralizing response against heterologous virus and the plasma HIV RNA level in HIV chronically infected group, while not in AIDS group. There was no association between the breadth of the neutralizing responses against heterologous virus and CD4 T cell counts. Conclusion The capacity of neutralizing antibodies against heterologous virus varied among different disease stage. There were higher titers of neutralizing antibodies in HIV chronically infected than AIDS group. The loss of neutralizing antibodies in plasma from AIDS group appears to be associated with a narrowing of the antibody response during disease progression. These suggest that the presence of neutralizing antibodies against hetreologous virus was associated with disease progression.

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.
