Objective To investigate the correlation between three gene locus polymorphisms of X-ray repair cross-complementary protein 1 (XRCC1) exon (Arg194Trp, Arg280His and Arg399Gln) and the risk of colorectal cancer (CRC). Methods A case-control study was performed in 250 CRC patients (case group, 128 colon cancer patients and 122 rectal cancer patients) and 213 healthy individuals (control group). The three gene locus polymorphism of XRCC1 was tested by polymerase chain reaction and restriction fragment length polymorphism (PCR-RFLP) method. The genotype distribution and allele frequency of each locus was analyzed with SPSS 10.0 software. Results There was no significant difference in allele frequency of XRCC1 at 194 and 399 loci (P > 0.05). However, the 280 Arg/His allele frequency of XRCC1 was higher in case group than that in control group (OR=1.66,95%CI:1.01~2.73,P=0.047). The 280Arg/His allele frequency was higher in rectal cancer group than that in control group (OR =1.82,95%CI:1.02~3.27). The frequency of 280His allele (Arg280His and His280His) was higher in case group than that in control group (OR=1.85,95%CI:1.06~3.22). However, it was a relative low risk factor of colon cancer and there was no significant difference between colon cancer group and control group (OR=1.85, 95%CI:1.06~3.22). Conclusions There was no correlation between XRCC1 Arg194Trp and Arg399Gln polymorpohisms and the risk of CRC. However, 280Arg/His genotype may increase the risk of CRC, and 280His allele is a risk factor of rectal cancer.

Objective To clarify the pathogenesis of spleen yin deficiency diabetes-associated cognitive decline (DACD) and mechanism of Zinu Piyin Recipe (ZBPYR) by observing the expression of phosphorylated RNA-dependent protein kinase-like endoplasmic reticulum kinase (PERK), eukaryotic initiation factor 2α subunit (eIF2α), p-eIF2α, glucose-regulated protein 78 (GRP78) in cerebral cortex of spleen yin deficiency diabetes mellitus rats. Methods The rats were randomly divided into control group, diabetes mellitus group, spleen yin deficiency group, spleen yin deficiency diabetes mellitus group (disease-syndrome group) and spleen yin deficiency diabetes mellitus+ZBPYR group (treatment group). Type 2 diabetes mellitus models were established by high-fat food feeding for 4 weeks and low dose STZ intraperitoneal injection. Then the classical compound method was used to construct spleen yin deficiency rats model by improper diet, over exertion and yin fluids exhaustion. The reatment group was given ZBPYR and other groups were given equal volume of normal saline for 15 days, then cerebral cortex was obtained. The expression of p-PERK, p-eIF2α, eIF2α and GRP78 were observed by Western Blot and RT-PCR. Results The protein expression of p-PERK, p-eIF2α, and mRNA expression of GRP78 of diabetes mellitus group, spleen yin deficiency group and disease-syndrome group was enhanced compared with control group (P<0.05). GRP78 protein expression of diabetes mellitus group, disease-syndrome group was increased compared with control group (P<0.05). The protein expression of p-PERK, p-eIF2α, GRP78 and mRNA expression of GRP78 of treatment group was decreased compared with diabetes mellitus group and disease-syndrome group (P<0.05). Conclusion Endoplasmic reticulum stress is involved in spleen yin deficiency DACD. ZBPYR improves learning and memory ability by reducing endoplasmic reticulum stress.
