OBJECTIVE: To summarize the advances in the genetic susceptibility to coronary artery disease (CAD) and explore the heritable basis of the disease.DATA SOURCES:Related articles in English from January 1990 to June 2006 were searched in Pubmed and EMCC databases with the terms "gene, coronary artery disease and myocardial infarction". Meanwhile, the CMCC database was searched for the relevant articles published between January 2000 and June 2006 in Chinese.STUDY SELECTrON: After the preliminary selection,relevant literatures on genetics of CAD and myocardial infarction(MI)were selected, and those with obvious indifferent contents or with less correlation were excluded.DATA EXTRACTION: Data of 49 articles were mainly extracted from the selected literatures providing solid evidence to elucidate the genetic susceptibility to CAD or MI.DATA SYNTHESIS: The involved 49 articles showed that CAD is a complex multifactorial disorder which is believed to result from the interplay between a person's genetic makeup and various environmental factors. The heritable basis is increasingly recognized as a crucial component in the development of CAD. Recent work in the field of genetics has lead to determining key genes associated with the susceptibility for CAD and MI through genome-wide linkage scans and large-scale gene-association studies as core human genetics approaches These susceptibility genes involve diverse functions, including dyslipidemia, vascular homeostasis, endothelial dysfunction, inflammation and immunity.CONCLUSION: The identification of genes that predispose to or directly cause CAD provides new insights into the pathogenesis of this disorder. However, the precise role of genetic factor in the CAD or MI events and the personalized gene-specific therapy await further investigation.

Objective To observe and analyze the changes of prostaglandin E2 (PGE-2)and elastase (EA)levels in the pulp blood of the patients with carious tooth complicated with exposed pulp and its influence on the curative effects of direct pulp capping treatment.Methods 80 cases of the patients with carious tooth complicated with exposed pulp treated with direct pulp capping treatment were selected as the observation group and 40 cases of the patients treated with normal removal of impacted third molar were selected as the control group.The levels of PGE-2 and EA in the pulp blood of the patients in the two groups before the treatments were detected and compared.A one-year follow-up was employed for the patients in the observation group and the curative effects were evaluated and compared.Results The levels of PGE-2 and EA in the pulp blood of the patients in the observation group were 132.28±63.55 ng/ml and 114.36±19.57μg/ml respectively,and the levels of PGE-2 and EA in the pulp blood of the patients in the control group were 0.61±1.26 ng/ml and 19.38±6.34μg/ml respectively.There were statistically significant differences between the two groups (t=43.129,29.675,P<0.05). There was a positive relationship between the PGE-2 level and EA level in the pulp blood of the patients in the observation group (r=0.782,P<0.05).The levels of PGE-2 and EA in the pulp blood before the treatment of the patients with suc-cessful effects were 84.63±13.17 ng/ml and 68.25±8.16μg/ml,and the levels of PGE-2 and EA in the pulp blood before the treatment of the patients with failed effects were 177.35±41.42 ng/ml and 152.36±16.28μg/ml.There were statisti-cally significant differences between the two types of patients (t=31.578,21.556,P<0.05).Conclusion The patients with carious tooth complicated with exposed pulp show the significantly increased expression levels of PGE-2 and EA in pulp blood.The higher expression levels of PGE-2 and EA before the treatment could put adverse influence on the curative effects of direct pulp capping treatment.The clinicians should give the comprehensive consideration to the specific condition of pa-tients to choose the proper treatment methods.

Objective To study the relationship between hepatocarcinogenesis and the mutation in X gene among patients with chronic hepa-titis B virus (HBV)infection,such as chronic hepatitis B (CHB),liver cirrhosis (LC)and primary liver cancer (PLC).Methods The serum samples from 89 patients with chronic HBV infection who visited the Second Affiliated Hospital of Chongqing Medical University from 201 1 to 2013 were collected.PCR was used to amplify the X gene of HBV DNA extracted from the serum samples.After sequencing,the HBV-X genome was compared with those reported in GenBank to find the variable sites and variant forms.Chi -square and one -way ANOVA were used for the statistical analysis afterwards,whereas genotypes were determined by the genotyping tool of the National Center for Biotechnology Information.Results All patients were genotype B or C.Among HBeAg-positive patients,46.2% were genotype B,and 53.8% were genotype C;among HBeAg-negative patients,81.2%were genotype B,and 18.8%were genotype C (P=0.001).PLC pa-tients had a significantly higher risk of mutation in the basic core promoter (BCP)region than the CHB and LC groups (69.2%vs 34.4%and 61.3%,P<0.05);in addition,an evident T-base deficiency was observed at nt1821 site (88.5% vs 53.1% and 71%,P=0.014).Among CHB and LC patients,those with genotype C had a significantly higher risk of BCP double mutation than those with geno-type B (61.5%vs 15.8%,P=0.007;83.3%vs 47.4%,P=0.045).The incidence of BCP double mutation was significantly higher in the low-viral load group (≤106 copies/ml)than in the high-viral load group (>106 copies/ml)(81.3% vs 47.9%,P=0.015). Conclusion The BCP double mutation and T-base deficiency at nt1821 site may play important roles in the development of PLC.
