With the further development of clinical modernization of traditional Chinese medicine (TCM), new request to tongue diagnosis for objectivity and quantification is raised. Many researchers have devoted themselves to this field and have achieved some accomplishments since 1950's. Especially in recent years, the revolution of information technique derived from computer industry brings the research new chances. The research history of the past five decades can be divided into three stages: (1) looking for micro-markers by newly-developed medical technique; (2) quantifying traditional markers by new technique; (3) further development based on information technique and corporation of multiple subjects. This article reviewed the three stages and described its prospect.

Objective: [WT5”,6BZ]To investigate the anti tumor effects of melittin in vitro . Methods: Melittin was isolated and purified from bee venom by gel filtration. The cytotoxicity of melittin against established cell lines(SMMC 7721,BEL 7402 and Hep 3B cell) was determined using by MTT assays. Mitomycin, vincristine and cinobu facini were used as control. The time effect relationship of melittin against SMMC 7721 cell line was studied. Results: Melittin showed the anti tumor effect in a dose dependent matter for tumor cells in vitro ,but there was no time effect relationship. The anti tumor effect of melittin was better than the control. Conclusion: Melittin has marked and quick anti tumor activity in vitro against established cell lines. [

Objective:To examine the relationship between cross-ethnic friendship and cross-ethnic face perceptual memory in the regions where the population ratios of the Uygurs and the Hans are different.Methods:According to demographic criteria,33 Han college students with lower contact with Uygurs from the area where Uygur and Han population ratio was 1 ∶ 9,32 Uygur college students with lower contact with Hans from the area where Uygur and Han population ratio was 9∶1,and 32 Uygur with higher contact with Hans and 34 Han students with higher contact with Uygurs from the area where Uygur and Han population ratio was 4∶6 were recruited in the study.Relying on E-prime program,the learning-recognition paradigm was adopted to compare the difference between the participants'recognition for faces of one's own race and others.Meanwhile,based on self-reported Friendship Quality Questionnaires,participants'Time Spent and Intimacy with out-group friends were assessed as the measurement of inter-group friendship.Results:The accurate rate,false alarm rate and discrimination accuracy demonstrated a significant own-race advantage for the Uygurs with lower contact and higher contact with the Hans (Ps ＜ 0.01),whereas the Hans with higher contact and lower contact with the Uygurs did not show significant difference between own-race faces and other-race faces on these variables (Ps ＞ 0.05).Stepwise regression analysis showed that the regression coefficients of the interracial intimacy and time spent with out-group friends toward the magnitude of crossrace effect were stably significant (β =-0.87,-0.56,Ps ＜ 0.01).Conclusion:The Uygur and Han students may prefer different encoding strategies in face recognition,and inter-group friendship experience may be an appropriate variable for predicting the ability to recognize other-race faces with good reliability and validity.

OBJECTIVE: To find out the rules of therapeutic methods, formulas and medicines of traditional Chinese medicine (TCM) for primary liver cancer (PLC). METHODS: The frequencies of treatments and medicines of TCM in 978 pieces of documents concerning PLC were analyzed. RESULTS: Among the 165 therapeutic methods, 277 formulas and 459 kinds of herbs, the methods for activating blood circulation, the formulas for regulating qi-flowing and the herbs for invigorating qi are the most commonly used. CONCLUSION: Therapeutic methods such as invigorating qi, regulating qi-flowing and activating blood circulation are the main choices for PLC, and the methods such as clearing heat, removing dampness and nourishing yin are used as supplements.

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 discover the connection between migraine and Tianmashouwu Tablet (TMT) in endothelial cell perspective. Methods: Serum containing TMT was added to rat's cerebral capilary endothelial cell's culture to observe the changes of NO and ET, and effect on express of ETmRNA and iNOSmRNA. Results: Levels of iNOSmRNA, rCMECs and ETmRNA were all downregulated, and contents of both NO and ET were decreased. Conclusions: TMT is effective in protection against rCMECs induced apoptosis, and has a therapeutic effect on migraine.

Object To establish a SDS PAGE method on quality control of melittin. Methods Melittin was extracted and purified from bee venom by gel chromatography. Purity and molecular mass of melittin were determined by SDS PAGE. Results In the gelatinous board, the sample was a single peptide chain with a molecular mass of about 2 800 dalton as revealed by SDS PAGE. The purity was (90 59?0 85)%, which was in parallel with the result tested by HPLC. Conclusion SDS PAGE is accurate, reliable and simple for the determination of melittin.

Objective:To isolate and purify melittin from bee venom and to establish an SDS PAGE and HPLC method for the determination of melittin content.Methods:Melittin was isolated and purified from bee venom by gel filtration on Sephadex G 25,Sephadex G 50 and Sephadex G 75.Homogenicity and molecular weight of melittin were determined by SDS PAGE and HPLC.Results:The sample was a single peptide chain with a molecular mass of about 3 000 dalton as revealed by SDS PAGE.The average recovery was 95.97% and RSD was 1.07%.Conclusion:Melittin prepared by a combination of gel filtration has high purity.The method for the determination of melittin with SDS PAGE and HPLC is accurate,reliable and simple.

Objective: To investigate the relationships between constitutional types of traditional Chinese medicine (TCM) and motion sickness. Methods: A survey of TCM constitutions in ocean sailors participating in a voyage was performed by using the TCM Constitution Questionnaire developed by Beijing University of Traditional Chinese Medicine, while the survey of motion sickness was operated by Graybiel's diagnostic criteria. The incidences of motion sickness among sailors with different types of constitutions were compared. Results: Prior to the voyage, 50.3% of sailors exhibited a gentleness constitution, 14.5% were of dampness-heat constitution, 10.3% were of qi-stagnation constitution, whereas the percentages of qi-deficiency, yang-deficiency, yin-deficiency, blood-stasis and special diathesis constitutions were 6.2%, 7.6%, 6.2%, 4.1% and 0.7%, respectively. None exhibited a phlegm-dampness constitution. By the end of the 176-day voyage, the percentages of gentleness, dampness-heat, qi-depression, qi-deficiency, yang-deficiency, yin-deficiency, blood-stasis, special diathesis and phlegm-dampness constitutions were 33.8%, 13.8%, 13.1%, 11.0%, 6.9%, 9.7%, 4.1%, 0.7% and 6.9%, respectively. The incidence of motion sickness was 69.7% (101 sailors) during this voyage. The incidences of motion sickness among sailors with different types of constitutions before the voyage showed significant difference (P<0.001). The incidence of motion sickness was higher in the sailors with dampness-heat constitution than in those with gentleness constitution. Conclusion: Types of Chinese medical constitution can be related to susceptibility to motion sickness. Furthermore, ocean voyage may have an effect or influence on the type of Chinese medical constitution of sailors involved.
