The full length cDNA of ?1,3 galactosyltransferase gene was amplified by RT PCR from the peritoneal macrophages of BALB/c mice, which was subcloned into an eukaryotic expression vector pCDNA3 1/V5 HisA, and it was confirmed by DNA sequencing. The gastric cancer cell GC9811 was transfected with pCDNA3 1/V5 HisA?1,3GT by Lipofectamine TM 2000. The positive clone was screened by G418 for two months and confirmed by RT PCR. The gastric cells expressing Gal?(1,3)Gal epitope were detected by immuohistochemisty, and they were killed by naive antidoby specific to Gal?(1,3)Gal epitope. The results showed that the pCDNA3.1/V5 HisA?1,3GT was successfully constructed, and the transfected gastric cancer cells could highly express Gal?(1,3)Gal, which promoted lysis of the cancer cells by normal human serum.

Objectives To optimize the curriculum for better education quality. Methods By literature review, the curriculum of the bio-medical English program of Peking University was summa-rized. Interviews were conducted on 8 sophomores of the program based on convenience sampling for their concerns over the curriculum and a questionnalre was designed based on such concerns. Ques-tionnalre survey was used for the remarks and suggestions of the 129 graduates of year 2002, 2003 and 2004 on the curriculum, with 79 valid questionnalres collected and the data analyzed by Microsoft Excel. Results Respectively 64 (81.02%), 52 (65.82%), 53 (67.09%) respondents believe the se-quence, duration and connection of the English courses are appropriate and 65 (82.27%), 46 (58.22%), 50 (63.29%) respondents believe the sequence, duration and connection of the medical courses are appropriate. 63 (81.77%) respondents hoped that they could do experiments in the medical courses, but 18 of them (23.08%) worried that the experiments would make the curriculum more tense. 71 (89.97%) respondents thought that the internship at hospital in the curriculum was conducive to better understanding of medical course contents . Suggestions on the improvement of the curriculum were also made by respondents. Conclusions The curriculum could be further optimized, especially on the connection between different courses, although most of the respondents by and large believe that the curriculum of the program is rational and hold positive attitude towards the internship in hospital and experiments in the curriculum.

To analyze the composition regularity of Carthami Flos-containing prescriptions of the Drug Standards of Ministry of Health of People's Republic of China-Traditional Chinese Medicine Preparations (the ministerial standards for Traditional Chinese Medicine) based on the traditional Chinese medicine inheritance support system (TCMISS, RZDZ No. 0389952). Efforts were made to identify 331 prescriptions containing Carthami Flos and summarize 16 attending functions and 10 commonly used drug combinations. Three commonly used drug combinations were selected for an in-depth analysis on Carthami Flos's combined administration regularity. Based on Carthami Flos's attending functions, its effects in paralysis, traumatic injuries and dysmenorrheal were compared to analyze Carthami Flos's core drug combinations for treating different diseases. The regularity of clinical administration and the characteristics of commonly used drug combinations were summarized to provide reference for Carthami Flos's clinical application and new ideas for new drug R&D. Carthami Flos prescriptions was mainly used to treat blood stasis and pain and mostly combined with drugs that could activate blood, promote the circulation of qi and dispel pathogenic wind to treat Qi-stagnation and blood stasis caused by various pathogenic factors such as wind, cold and dampness.
