OBJECTIVETo detect the mutation sites of exons 2, 20, 11A and 11B in Chinese patients with breast cancer.

METHODSA total of 86 patients with breast cancer without blood relationship were randomly selected. Polymerase chain reaction (PCR) and double-strand DNA direct sequencing were applied.

RESULTSNo mutations, especially deletions were found in exons 2, 20 and 11 with carefully checking the sequencing results, although they were reported frequently in Europe populations with breast cancer. We found one polymorphism in exon 11, with high frequency, and in the test of chi-square, the frequencies of two alleles had no significant difference between the patients and controls.

CONCLUSIONThe above results suggest this SNP may not be associated with the breast cancer in Chinese population, and indicates that the gene sequence of what we have studied doesn't account much for occurrence of the breast cancer in the population of China.

Talents are the main force for the development of traditional Chinese medicine（TCM）， and the construction of TCM talents and the reformation of talent evaluation system are essential to promote the inheritance and innovation of TCM. At present， we are still exploring and developing in the fields of the formulation， implementation and evaluation indicators of TCM talent evaluation system. However， there are shortcomings and difficulties. For instance， insufficient stratification in the evaluation， excessive emphasis on the quantity of achievements， neglecting the quality of the achievements and the actual contribution， imperfect assessment indicators， and the weak characteristics of TCM. Therefore， national ministries and commissions have jointly issued a document requesting to break the four only and set a new standard， in order to promote the construction of a scientific and technological talent evaluation system oriented by innovation value， ability and contribution. For the evaluation of TCM clinical talents， China Association for Science and Technology commissioned China Association of Chinese Medicine to build the China Clinical Cases Library of TCM（CCCL-TCM）， which aims at collecting the most authoritative and representative TCM clinical cases and exploring the advantages of applying clinical cases as masterpiece of achievement in TCM clinical talents evaluation. CCCL-TCM can promote the construction of a talent evaluation system that is more in line with the development characteristics of TCM industry， and to carry out relevant pilot in TCM colleges and institutions across the country in order to promote the reformation of TCM talent evaluation system.
