Objective To explore the relationship between angiotensin Ⅱ type 1 receptor (AT1R) gene polymorphisms and cerebrovascular disease (CVD).Methods The 104 patients with CVD and 98 healthy individuals were detected the AT1R genotypes polymorphisms by restriction fragment length polymorphism in order to analysis.Results CC genotype was not found both in CVD and control group. In CVD group, genotypic frequency of AA was 40.4% and AC was 59.6%. The allele frequency of A was 70.1% and C was 29.9%. In control group, genotypic frequency of AA was 91.8% and AC was 8.1%. The allele frequency of A was 95.9% and C was 4.1%. AT1R polymorphism revealed there was significant difference between the genotype and allelic distribution in CVD patients and those of in controls (all P

Objective To investigate the relationship between polymorphisms of angiotensinogen(AGT) gene T704C and cerebrovascular disease(CVD).Methods AGT T704C genotype and allele were examined by PCR-RLFP in 82 patients with cerebral infarction(CI group),70 patients with intracerebral hemorrhage(ICH group) and 89 age-matched normal controls(NC group).The AGT T704C genotype and allele frequencies among the 3 groups were compared and analyzed.The effectes of AGT T704C genotype and the risk factors of stroke to induce CI snd ICH were analyzed by Logistic regression. Results The frequencies of AGT 704CC genotype and C allelic in CI group(63.4%,79.9%) were significantly higher than those in NC group(34.8%,61.2%)(allP

Objective To explore the relationship between angiotensin I-converting enzyme(ACE)gene I/D and angiotensin Ⅱ type 1 receptor(AT1R)gene A1166C polymorphisms and cereral infarction(CI).Methods ACE and AT1R genotypes were investigated with the method of PCR-RLFP in 88 patients with CI and compared with 90 age-matched population controls.Results AC genotypic frequency(31.8%)and C allele frequency(15.9%)of AT1R gene in CI group were significently higher than those in control group(11.1%,5.6%)(all P0.05).Conclusions The polymorphism of AT1R A1166C is related to the incidence of CI.There are synergistic effects of ACE DD genotype and AT1R gene A1166C polymorphisms on the risk of CI.

With the constant deepening of the study in the genetic factors of eardio-cerebrovascular diseases, the relation between the renin-angiotensin system (RAS) gene polymorphisms and hypertension is increasingly receiving attention. As an important component of RAS, renin has received much concern in the genetic research of cardio-cerebrovascular diseases and its gene polymorphisrns have become the candidate genes of hypertension, coronary heart disease and stroke, etc.

Objective To investigate the relationship between renin (REN) gene G10631A, angiotensinogen (AGT) gene T704C mononucleotide polymorphisms and cerebral infarction and to investigate the mechanisms and characteristics of cerebral infarction from molecular level. Methods REN gene G1063A and AGT gene T704C polymorphisms in 82 patients with cerebral infarction and 89 controls were detected with polymerase chain reactionrestriction fragment length polymorphism. The differences of the genotypes and allele frequencies were compared between the patient group and the control group. Results The frequency of REN 10631AA genotype (31. 7% vs. 10. 1%,χ2 =12. 816, P = 0. 002) and the frequency of A genotype (49. 4% vs. 30. 3% χ2 = 12. 969, P =0. 000), as well as the frequency of AGT 704 CC genotype (63. 4% vs. 34. 8% χ2 = 15. 029, P = 0. 001) and the frequency of A genotype (79. 9% vs. 61. 2% χ2 = 14. 173, P = 0. 000) in the cerebral infarction group were all significantly higher than those in the control group; the frequency of haplotype 704C 10631A was also significantly higher than that in the control group (P=0. 000). Conclusions REN 10631AA genetype and A allele as well as AGT 704 CC genetype and C allele may be the susceptible factors of cerebral infarction. Haplotype 704C-10631 A may be a genetic risk factor for the occurrence of cerebral infarction.

Objective To investigate the ischemic injury of hepatic cell caused by hepatic artery occlusion.Methods The hepatic artery was occluded in 20 dogs via operation,while the portal vein remained patent.Specimens were gained from the right liver at four time points:before occlusion of the hepatic artery,20(minutes),40 minutes and 60 minutes after artery occlusion.Each specimen was examined by HE and BCL-2 by immunohistochemistry.The gray scale of BCL-2 in HE sections was detected.Results Hepatic cellular injury was obvious 20 minutes after occlusion of the hepatic artery.Irreversible hepatic cellular injury was(observed) 60 minutes after hepatic artery occlusion.The results showed that the gray scale of BCL-2 at every time point after hepatic artery occlusion were significantly different from that before hepatic artery occlusion(P

Free fatty acids, as important energy metabolism substrates for the heart, play an important role in various cardiovascular diseases; ω-3 PUFA, as an important branch of free fatty acids, has been confirmed by more and more researches to be closely related to cardiovascular diseases. Heart failure, as a common cardiovascular problem, seriously affects people's quality of life. Studies have shown that ω-3 PUFA plays a significant role in the development of heart failure. In this paper, we try to review the metabolism, pathogenesis and therapeutic significance of ω-3 PUFA in heart failure.
