This paper shortly introduced the MIT President Susan Hockfield's ideas about three life-science revolutions from the middle of the 20th century to now.Then,writers investigated the problems of interdisciplinary combination between medicine and engineering in research universities of China,and put forward some suggestion aboat how to face the third life-science revolution.

Objective To investigate teaching situation of Introduction to Medicine at SJTUSM,and to make more progress in educational reforms. Methods By analyzing questionnaire and test paper,the relevant information was collected and analyzed by SPSS statistics software. Results Teaching the course at SJTUSM was basically satisfactory. Conclusion The investigation showed that the teaching quality of the course is being improved. However,the quality guarantee system of teaching process needs to be further perfected.

Objectives To compare the co-infection statues of HSV, HBV and HCV in patients with STD and HIV infection for providing evidence of developing prevention and control strategies. Methods Serum samples confirmed to be infected with HIV/AIDS by Western blot, and serum samples of patients with STDs (syphilis, gonorrhoea and chlamydial infection) were tested for HSV2-IgG, HSV2-IgM, HBsAg and HCV-IgG by ELISA. The detection levels were compared between the two groups. Results Out of 76 specimens in STD group, HSV2-IgG was detected in 24 specimens (31.58%), HSV2-IgM in one specimen (1.32%), HBsAg positive in 8 (10.53%), and HCV antibody positive in 4 (1.32%). In 14 specimens of HIV/AIDS group, HSV2-IgG were detected in 7 (50.00%); HSV2-IgM in 5 (35.71%);8 (578.14%) were positive for HBsAg and 3 (21.43%) for HCV. In a total of 90 specimens, both HSV and HBV were detected in 6 specimens, both HSV-IgM and HBV in 2, and the four above-mentioned antibodies in 2. The infection rates of HSV, HBV and HCV were significantly higher in HIV-infected specimens than those in the STD specimens (P

To improve the quality of postgraduate students,school of medicine of Shanghai Jiao Tong University have offered medical molecular genetics course to postgraduates and obtained good teaching efficiency. More than ten professors gave lectures on the academic foreland,leading students to find and solve academic problems and training practical and innovative ability of students. Accord-ing to the questionnaires of evaluation of the course and suggestions from postgraduates in the recent two years,some recommendations for the further teaching reform were proposed,such as using multi-plex teaching models,strengthening communication for teaching information with the students,em-ploying comprehensive evaluation methods and strengthening coordination and management of the course.

As a neotype learning mode, team-based learning has been applied in some medical schools and has become one of the most common self-regulated learning modes around the world. According to the process of team-based learning in medical classes at University of British Columbia in Canada. In terms of its effects, we discuss its advantages and shortcomings, and analyze its application status and im-plementation difficulties in China, and then propose several suggestions on domestic medical education.

Objective To explore the multi-modal MRI characteristics of breast cancers in dense breasts.Methods 120 patients with breast cancer shown on mammography underwent breast MRI,which were solitary and confirmed by pathological examination. According to the BI-RADS classification of breast,the 120 cases were divided into two groups including dense type breast and non-dense type one.The differences in morphological features,ADC values (b=1 000 s/mm2 )and time-signal intensity curve (TIC)of the lesions between two groups were analyzed and compared.Statistical analysis was performed using SPSS1 6.0.Results The breast cancers in dense breast were vulnerable to have a spiculated margin (44/68 in the dense breast group vs.1 6/52 in the non-dense breast group,P =0.000).The size of the lesion in dense breast (1.83 ±0.98)cm was bigger than that in non-dense breast (1.40±0.46)cm (P =0.005).The non-mass-like enhancement of the lesion in dense breast was much more than that in non-dense breast (P =0.000).In addition,the average ADC values of the lesion in dense breast (0.89±0.12)×10 -3 mm2/s were lower than in non-dense breast (0.95±0.10)×10 -3 mm2/s(P =0.01 6).Conclusion The breast cancer in the dense breast has different MRI findings in comparison with non-dense breast.

OBJECTIVETo identify potential mutation in a Chinese family affected with Charcot-Marie-Tooth disease(CMT).

METHODSClinical data of the family was collected, and genomic DNA was extracted from peripheral blood samples of the family members. Seventy-two candidate genes of the proband were captured and sequenced by targeted next-generation sequencing, and the results were confirmed by Sanger sequencing. The protein structure was predicted with PyMOL-1 software.

RESULTSA homozygous missense mutation c.1894G>A(p.E632K) was identified in the exon 11 of the SH3TC2 gene in the proband. Heterozygous c.1894G>A mutation was also detected in the proband's father, mother and daughter, but not in the healthy family members and 300 normal controls. Retrieval of the NCBI, HGMD and 1000 genome databases has verified the c.1894G>A to be as a novel mutation. Computer simulation has suggested that the mutation has altered the 3D structure of the SH3TC2 protein.

CONCLUSIONThe proband was diagnosed as CMT4C, for which the underlying gene was SH3TC2. This finding has expanded the spectrum of SH3TC2 mutation in association with CMT4C.
