Objective:To analyze the correlation of single nucleotide polymorphisms ( SNP) of ATP binding cassette transporter A1 gene (ABCA1) and lower extremity atherosclerotic disease (LEAD). Methods: The clinical data and peripheral blood were col-lected from 630 participants (314 LEAD cases and 316 normal controls) in Han population of Minnan. The 9 SNP genotypes in the ABCA1 gene were detected by Sequenom MassArray. Results:Among the 9 SNP genotypes, rs2980083 was rejected because it wasn' t in accordance with Hardy-Weinberg equilibrium. Obvious linkage disequilibrium was found between rs2066714 and rs2066715, rs1800976 and rs2246293, rs2246293 and rs2980083, and rs1800976 and rs2980083(D′>0. 9,r2 >1/3). There were no significant differences (P>0. 05) in 6 haplotypes of ABCA1 gene groups between the LEAD cases and the normal controls. No significant differ-ences (P>0. 05) were found in frequency distribution between the LEAD cases and the normal controls in 8 SNP according to the re-sults of genotype statistics. There was no onset risk of LEAD according to the gene logistic regression analysis. Conclusion:The SNPs of rs10124755, rs2980083, rs1800976, rs4149341, rs2066714, rs2066715, rs2066716, rs2230808 and rs2246293 might not correlate with the susceptibility of LEAD in Han population of Minnan.

Objective:To analyze the association between gene single nucleotide polymorphisms ( SNP) of methylenetetrahydrofo-late reductase ( MTHFR) gene and lower extremity atherosclerotic disease ( LEAD) . Methods:The clinical data and peripheral blood were collected from 384 participants (224 LEAD cases and 160 normal controls) from Han population of Minnan Fujian. LEAD was detected with ankle brachial index ( ABI) , toe brachial index ( TBI) , color Doppler ultrasonic examination and the other imaging stud-ies. The SNP genotypes including rs1801133, rs1801131, rs2274976, rs4846048, rs3737966, rs1537515, rs4846049, rs3834044, rs13306561 and rs3737964 in the MTHFR gene were detected by matrix-assisted laser desorption ionization-time of flight ( MALDI-TOF) . Results:The genotype distributions of the ten loci were in accordance with Hardy-Weinberg equilibrium. There were 37 obvi-ous linkage disequilibrium, including the association between rs4846048 and rs3737966 (D′>0. 9) and so on. There were significant differences (P=0. 02) in GCCTCGGAAT haplotypes of MTHFR gene groups between LEAD cases and the normal groups. The results from chi-square test of allele frequencies suggested rs1801131 (OR=1. 287),rs4846048 (OR=1. 844,P=0. 02), rs3737966(OR=1. 339),rs4846049 (OR=1. 314) and rs3737964 (OR=1. 522). Significant differences (P<0. 05) were observed between LEAD and the normal groups in Cochran- Armitage trend test and Dominant gene action test of rs4846048. Conclusion: The SNP of rs1801131,rs4846048,rs3737966,rs4846049 and rs3737964 might be associated with the susceptibility of LEAD,and rs4846048 gene mutation might serve as a risk factor for LEAD in the community-based population.

BACKGROUND: Both Allergic rhinitis and bronchial asthma are allergic diseases of respiratory tract. They frequently coexist in the same patients.OBJECTIVE: To study the incidence of allergic rhinitis in patients with bronchial asthma in Nanjing, and to analyze the correlation of clinical characteristic between allergic rhinitis and bronchial asthma.DESIGN: The questionnaire survey.SETTING: Department of Otorhinolaryngology-Head and Neck Surgery and Department of Respiratory, Nanjing General Hospital of Nanjing Military Area Command of Chinese PLA.PARTICIPANTS: A total of 134 patients with bronchial asthma including 73 males and 61 females were selected form Nanjing General Hospital of Nanjing Military Area Command of Chinese PLA from February 2001 to April 2005. Their ages ranged from 3 to 72 years. Severity of asthma of all patients was classified based on Global Initiative for Asthma (GINA). The diagnostic criteria of allergic rhinitis were established referred to the guideline of Haikou Meeting (November, 1997). All patients provided the confirmed consent.METHODS: The questionnaire survey of 134 bronchial asthma patients from the city of Nanjing was conducted. Their age, classification, severity, treatment status, and the family history of all 134 patients were investigated in details. Differences of age, age at onset, and course of disease between rhinitis and asthma of all patients were examined by two independent t tests. The correlation between clinical characteristics of allergic rhinitis and bronchial asthma was analyzed by Spearman rank correlation.MAIN OUTCOME MEASURES : Incidence of allergic rhinitis in patients with bronchial asthma and the correlation of clinical characteristic between allergic rhinitis and bronchial asthma.RESULTS:Of all 134 bronchial asthma patients,82(61.2%,82/134)were accompanied with allergic rhinitis.There were 45 males and 37 females.Of 82 patients with allergic rhinitis accompanying with bronchial asthma,severity was classified into grade Ⅰ (mild pause,n=56),grade Ⅱ (mild persistence,n=21),grade Ⅲ (moderate persistence,n=4),and grade Ⅳ (severe persistence,n=1).In addition,allergic rhinitis was classified into periodicity (n=65) and persistence(n=17).According to the classification and seventy system recommended in ARIA,63 patients had mild symptoms and 19 had moderate and severe symptoms.Severity of allergic rhinitis was positively related to that of bronchial asthma(r=0.689,P<0.01).CONCLUSION: The morbidity of allergic rhinitis combining with bronchial asthma is high in Nanjing, China. While, their classification and severity are highly coherent.

Connexin43 has been shown to play a pivotal role in wound healing process. Wound repair is enhanced by acute downregulation of connexin43, by increasing proliferation and migration of keratinocyte and fibroblast. Angiogenesis is also a central feature of wound repair, but little is known about the effects of connexin43 modulation on functions of endothelial cells. We used connexin43 specific small interference RNA (siRNA) to reduce the expression of connexin43 in human umbilical vein endothelial cell (HUVEC), and investigated the effects of connexin43 downregulation on intercellular communication, viability, proliferation, migration and angiogenic activity of HUVEC. Treatment of siRNA markedly reduced the expression of connexin43 by -80% in HUVEC (P < 0.05), and decreased the intercellular communication by -65% (P < 0.05). The viability, proliferation, migration and angiogenic activity of HUVEC decreased significantly (P < 0.05), compared with that of the normal cells. The results suggest that temporally downregulation of connexin43 expression at early stage of wound to inhibit the abnormal angiogenesis characterized with leaky and inflamed blood vessels, maybe a prerequisite for coordinated normal healing process.
