Objective To investigate the association of genetic polymorphism in the advanced glycation endproduct (RAGE) gene with genetic susceptibility to ischemic stroke.Methods A case-control study was conducted with 124 ischemic stroke patients serving as the stroke group and 125 healthy volunteers serving as the control group.Three common polymorphisms in the RAGE gene,82G/S (rs2070600),-429T/C (rs1800625) and-374T/A (rs1800624),were genotyped by the polymerase chain reaction-restriction fragment length polymorphism (PCR-RELP) method.The association between the three polymorphisms and genetic susceptibility to ischemic stroke was further analyzed by logistic regression analysis.Results The body mass index (BMI),diastolic blood pressure,blood lipids levels,and the percentage of smokers were significantly higher in the stroke group than in the control group (each P＜0.05).At the 82 position,the frequencies of the genotypes GG,GS and SS were 10％,48％ and 42％,respectively.At the 429 position,the frequencies of the genotypes TT,TC and CC were 15％,44％ and 41％,respectively.At the 374 position,the frequencies of the genotypes TT,TA and AA were 8％,41％ and 50％,respectively.After adjusting for confounding factors including age,gender,smoking and blood pressure,the genotype frequencies of SS and S alleles at 82G/S of the RAGE gene were higher in the stroke group than in control group (SS:OR=2.14,95％ CI:1.37-3.51;S:OR=1.96,95％ CI:1.24-3.34),while no significant differences of genotype frequencies of the 429T/C and-374T/T polymorphisms were observed between the stroke group and the control group (each P＞0.05).Conclusions The 82G/S gene polymorphism of the RAGE gene has correlations with ischemic stroke in the Henan Han population,with the S allele as the risk factor for ischemic stroke.However,no clear association between the 429T/C or-374T/A polymorphisms of the RAGE gene and ischemic stroke is identified in the Han population.

Objective To investigate the diagnostic and therapeutic characteristics of prostate cancer with prostate specific antigen(PSA)4-10?g/L. Methods The data of prostate biopsies for the patients with PSA 4-10?g/L from May 1998 to February 2004 and the treatment and prognosis of these patients were retrospectively analyzed. Results In the 141 cases, 34 were diagnosed as prostate cancer, including 3 cT1, 21 cT2, 6 cT3 and 4 cT4. Mean Gleason score was 5.8, and the mean Gleason scores of cT1 and cT2 were significantly lower than those of cT3 and cT4. Twenty-four cases of cT1 and cT2 underwent radical prostatectomy. Four cases of cT3 recieved radical prostateetomy after 4 months of neoadjuvant endocrine therapy. Two cases of cT3 and 4 cT4 received castration. Pathological section from radical surgeries showed that 21 cases were organ confined and 7 were locally invasive. The difference of mean Gleason score between these two groups was significant in statistics. After 18 to 69 months (mean 42 months)follow-up, 21 organ confined cases were free survived, 4 locally invasive cases had biochemical recurrence and 1 case had multifocal bone metastasis. No cancer-specific death happened. Two of 4 cT4 cases were still alive and 2 died of the tumor. Conclusions Routine needle biopsy is necessary for the cases with“grave area”PSA of 4～10 ?g/L. Prostate cancers with PSA 4～10/?g/L are not always early diseases. Gleason score is a very important index for determine the stage of pathology after surgery. Radical prostatectomy is an effective treatment for organ confined disease.
