Clinical simulation training improves the clinical performance of Chinese medical students.

Background: Modern medical education promotes medical students' clinical operating capacity rather than the mastery of theoretical knowledge. To accomplish this objective, clinical skill training using various simulations was introduced into medical education to cultivate creativity and develop the practical ability of students. However, quantitative analysis of the efficiency of clinical skill training with simulations is lacking.

[Establishment and preliminary application of multiplex PCR for detecting the microsatellite markers in silkies].

In order to obtain the stable PCR combinations for silkies genetic analysis, multiplex PCR was used and its reaction condition was optimized. Five combinations of multiplex PCR with good effects were obtained from eighteen microsatellite markers. Three of them were quadruplex-PCRs, and two were triplex-PCRs.

[A linkage map of mirosatellite on chromosome 1 in Liangshan semi-wool sheep].

The 9 microsatellite markers on Chromosomes 1 were used to construct a linkage map of Liangshan semi-wool sheep with a 387 members half-sib pedigrees after paternity testing. The results were as follows: the number of alleles for 9 markers was from 5 to 15; the heterozygosity was from 0.202 to 0.
