This paper introduces the development and application of health-related quality of life (HRQOL) scales in research on coronary heart disease (CHD). Currently, the scales for CHD patients have been more systematically developed and widely used in foreign countries, while domestically in China, they are developed successfully but problematically; research in this field has started later and the scales introduced are limited and not suitable for the entire range of domestic CHD patients. Thus, this paper introduces 26 HRQOL scales in research on CHD, including five generic scales, ten disease-specific scales from abroad and eleven scales originating from China. With the deficiency of HRQOL scales, especially that in traditional Chinese medicine and specific scales, this paper analyzes and summarizes the problems existing in development of scales. The authors also provide solutions in order to help the development and application of scales in further studies.

Objective To explore the association between SLC2A9,SLC17A3,ABCG2 single nucleotide polymorphisms and gout susceptibility in Quanzhou.Methods One hundred and fifty-four cases of gout patients and 160 healthy controls were selected,single nucleotide polymorphisms (SNP) of SLC2A9 SLC17A3,ABCG2 with tri-primer polymerase chain reaction (PCR) were tested and the relation between different genotypes and primary gout prevalence were analyzed.Results High risk genotype frequency of rs16890979 was 93.5％ and 70.0％ in patients and healthy people,respectively (the difference of genotype frequency between the two groups was statistically significant (x2=55.377,P＜0.01).High risk allele frequency was 79.9％ and 48.4％ in patients and healthy people,respectively (allele frequency in different population was statistically significant,x2=67.128,P＜0.01).High risk genotype frequency of rs2231142 was 68.8％ and 38.7％ in patients and healthy people,respectively (the difference of the genotype frequency was statistically significant,x2=29.129,P＜0.01);High risk allele frequency was 43.5％ and 23.4％ in patients and healthy people,respectively (the difference of allele frequency was statistically significant,x2=28.468,P＜0.01) ; rs1165205was a protective SNP,low risk genotype frequency was 42.2％ and 45.6％ in patients and healthy people,respectively (the difference of genotype frequency was statistically significant,x2=0.373,P=0.571); High risk allele frequency was 26.0％ and 28.1％ in patients and healthy people,respectively (the difference of allele frequency was not statistically significant,x2=0.270,P=0.364).Conclusion SNP loci rs16890979 of SLC2A9 gene and rs2231142 of ABCG2 gene can be used as genetic markers for primary gout susceptibility in the Quanzhou area,but SNP loci rs1165205 of SLC17A3 gene has little correlation with the prevalence of primary gout in Quanzhou residents.

The paper was aimed to review the modeling methods of spleen-yang deficiency, which can be classified into imitating traditional Chinese medicine (TCM) etiology methods and modern medicine methods. At present, methods of modeling were not generally accepted and the main presented problems were as follows. Modern medicine methods did not conformed to the rules of TCM etiology and pathogenesis. The evaluation of yang deficiency models was not accurate. Some modeling methods can lead to other diseases at the same time. The names of spleen deficiency model were not unified. It was difficult to distinguish the modeling methods of spleen-yang deficiency and spleen-qi deficiency, and etc. Model evaluation of spleen-yang deficiency was various. However, the domestic standard evaluation system had not been formed. The main model evaluation problems were as follows. Macro symptoms of the model lacked of objective and quantitative evaluation. It lacked of evaluation indexes of pulse and tongue with TCM characteristics. The disproof of prescription selection was not unified. Similar syndromes had not been ruled out. The microscopic indexes were fragmented, and etc. This paper reviewed on animal modeling methods of spleen-yang deficiency.

Aptamers are capable of binding a wide range of biomolecular targets with high affinity and specificity. It has been widely developed for diagnostic and therapeutic purposes. Because of unique three dimensional structures and cell-membrane penetration, aptamers inhibit virus infection not only through binding specific target, such as the viral envelope, genomic site, enzyme, or other viral components, but also can be connected to each other or with siRNA jointly achieve antiviral activity. Taking human immunodeficiency virus and hepatitis C virus as examples, this paper reviewed the effects and mechanisms of aptamers on disturbing viral infection and replication steps. It may provide an insight to the development of aptamer-based new antiviral drugs.

Objective A very high prevalence of rheumatoid arthritis (RA) is observed in Minnan population in China.We aimed to explore the genetic characteristics of RA in Minnan population and genetic mechanisms of RA by studying the associations of three single nucleotide polymorphisms (SNPs) of signal transducer and activator of transcription 4 (STAT-4) (rs7574865),the cytotoxic T-lymphocyte antigen-4 (CTLA)-4 (rs3087243) and chromosome 9p21.3(rs1333049) with RA in Minnan population.Methods A case-control study of 119 RA patients and 125 normal controls from Quanzhou were enrolled.SNPs (rs7574865,rs3087243,rs1333049) were genotyped by allele-specific polymerase chain reaction (PCR) and analyzed by SPSS 18.0.x2-test was applied to compare allele and genotype frequeneies betweeen cases and controlsLogistic regression models were used to analyze the SNPs.Results The results showed the genotype distributions of STAT4 genes were significantly different between case and control groups (P＜0.01).Compared with the GT heterozygous genotype,TT and GG homozygosity carriers had a lower risk (OR=0498 and 0.300,P=0.018 and P=0.002 respectively).There was not statistical difference in genotypes and allele in CTLA-4 (rs3087243) between RA patients and healthy controls (x2=4.083,P=0.130),but compared with the AG genotyoe,GG homozygosity carriers had a lower risk on basis of statistics (OR=0.580,P=0.04).There was not statistical difference in genotypes and allele in the chromosome 9p21.3 (rs1333049) (P＞0.05),but compared with the GG genotype carriers,CC and GC genotypes carriers had a lower risk on basis of statistics (OR=0.565,P=0.0495).Conclusion Chromosome 9p21.3 (rs1333049) and CTLA-4 rs3087243 G/A may not be associated with susceptibility to RA in Minnan popula-tions.This replication study confirmes that STAT4 rs7574865 G/T polymorphism is associated with susceptibility to RA in Minnan population.

BACKGROUND:Olfactory ensheathing cells (OECs) have been shown to possess the potential of repairing injured spinal cord, but their biological characteristics after transplantation in vivo are not well understood.OBJECTIVE: To investigate the migration of OECs after transplantation into the injured spinal cord of adult rats.DESIGN: Randomized and controlled experiment.SETTING: Department of Orthopedics, Guangdong Provincial People's Hospital; Experimental Animal Center of the North Campus of Sun Yat-sen UniversityMATERIALS: Totally 38 2-month-old male SD rats with body mass of (350 ±20) g were used in this study.METHODS: This experiment was conducted in the Experimental Animal Center, North Campus of Sun Yat-sen University between February 2004and May 2004. Two SD rats were used to extract the OECs, which were stained with Hoechst 33342. Totally 36 SD rats were subsequently randomized into 3 groups, namely rostral transplantation group, caudal transplantation group and control group with 12 rats in each group. The rats in the rostral and caudal transplantation groups subjected to operations to establish thoracic spinal cord injury model and OEC suspension was injected; in the control group, the rats were spared of thoracic spinal cord injury with only OEC suspension injection.MAIN OUTCOME MEASURES: Distribution of OECs in the spinal cord was observed under fluorescence microscope 1, 2, 4 and 6 weeks after operation, respectively.RESULTS: Of the rats in the 3 groups, 1 died in the rostral group, and 2in each of the caudal transplantation and control groups, leaving 29 rats for result analysis. The OECs in the rostral and caudal transplantation groups migrated longitudinally along the long axis of the spinal cord to a farthest distance of 8 mm and penetrating the scar tissues, but very few cells could reach the contralateral side. The OECs in the control group diffused locally without migration.CONCLUSION: OECs mainly migrate along the axons in white matter of the injured spinal cord, and their rostral and caudal migration does not differ in speed or amount. Only a small amout of OECs can across the transected gap of the spinal cord.
