Objective To investigate the relation of single nucleotide polymorphisms (SNP)45T/G the adiponectin gene with type 2 diabetes of Han nationality in Ningxia.Methods PCR-RFLP method was used to identify the distribution of alleles and genotypes frequencies of SNP45T/G polymorphisms in adiponectin gene in 100 type 2 diabetic patients and 101 normal subjects.Results The distribution of genotypes and alleles frequencies of the SNP45 polymorphisms were significantly different (GG genotype:13% vs 3%,P

Objective:To improve teaching quality of laboratory teaching in medical cell biology on foreign students.Methods:To improve teaching language,teaching material,teaching methods and so on.Results:We got significant improvement on laboratory teaching of foreign students in medical cell biology.Conclusion:In order to improve teaching quality of laboratory teaching in medical cell biology on foreign students,we should improve on many different ways and accumulate experiences for future teaching.

OBJECTIVETo compare the distribution of (CAG)n and (GGN)n repeats polymorphisms of androgen receptor (AR) gene between Hui and Han ethnic Chinese from Ningxia.

METHODSGenotypes of above repeats were determined with DNA sequencing method.

RESULTSThe distribution of (GGN)n repeats was significantly different between the two ethnic groups (P< 0.01), though no such difference was detected with (CAG)n repeats (P> 0.05). Particularly, Han Chinese women carrying 23 GGN repeats were significantly fewer (48.4%) than Hui women (64.7%, P=0.01).

CONCLUSIONThe distribution of GGN repeat is significantly differently among Hui and Han Chinese ethnics from Ningxia.
