A study was conducted on 220 patients with the first ischemic infarction due to atherosclerosis treated at Stroke Unit of People Hospital No 115 from January 2002 to April 2002, and 230 control subjects. Results: Among 220 cases of ischemic infraction, there were 112 female and 108 male, mean ages 60.71 ±11.9 years old. Among them, 20% is due to large artery thrombosis and the mean plasma homocystein levels was 14.4µmol/L, 80% is due to small artery thrombosis and the mean plasma homocystein levels is 13µmol/L. There was no significantly difference in the mean plasma homocystein levels between large artery thrombosis and small artery thrombosis (p=0.1). The adjusted odd ratios (OR) for large artery and small artery infarctions associated with moderate hyperhomocysteinemia (>1515µmol/L) were 2.56 and 2.20, respectively

Hyperhomocysteinemia (HHcy) is considered to be one of the most important cardiovascular risk factors. Epidemiological studies conducted on erectile dysfunction (ED) have demonstrated its close correlation with cardiovascular disease, and therefore HHcy might be a novel risk factor of ED. However, the mechanism of ED resulting from HHcy is not precisely known, but may relate to increased damage of vascular endothelial cells, reactive oxygen species (ROS), and atherosclerosis. Although further studies are needed on this association between HHcy and ED, the measurement of plasma Hcy and folic acid levels and molecular analysis of the MTHFR genotype might be added to the ED diagnostic procedure, especially in young patients or in those with a family history of cardiovascular disease. Treatment of ED patients with HHcy should first aim to reduce the Hcy level through administration of folic acid, alone or in combination with vitamin B6 or B12, and then proceed to treatment with PDE5i. This paper offers an overview on the advances in the studies of the correlation between HHcy and ED.

Homocysteine (Hcy) is an intermediate metabolite of methionine metabolism. Hyperhomocysteinemia (HHcy) is defined as a condition characterized by plasma Hcy level above 16 μmol/L which can result from abnormal Hcy metabolism. HHcy has been confirmed to be related to cardio-cerebrovascular disease, peripheral vascular disorders, neurodegenerative diseases, diabetes, pregnancy-induced hypertension syndrome, liver cirrhosis and kidney diseases. In this review, we summarize the correlation between HHcy and kidney diseases. Elucidating the role of HHcy in kidney diseases may provide a new strategy to prevent and treat kidney diseases.

OBJECTIVE: To analyze the methylenetetrahydrofolate reductase (MTHFR) mutation in patients with recurrent spontaneous abortion. MATERIAL AND METHOD: The blood samples of patients with recurrent spontaneous abortion were tested by PCR-RFLP method. RESULTS: Of 51 cases of study group, 14 (27.5%) were normal, 25 (49.0%) were heterozygosity, and 12 (23.5%) were homozygosity. Of 58 cases of control group, 20 (34.5%) were normal, 30 (51.7%) were heterozygosity, and 8 (13.8%) were homozygosity. But the difference between two groups was not significant (p=0.190). CONCLUSION: Hyperhomocysteinemia due to MTHFR mutation is a cause of recurrent spontaneous abortion. Therefore, the study for MTHFR mutation should be included in the workup of recurrent spontaneous abortion.

PURPOSE: To investigate levels of serum homocysteine in patients with pseudoexfoliation syndrome and the association between serum homocysteine levels and risk of coronary heart disease. METHODS: From March 2013 to September 2013, 37 patients with pseudoexfoliation syndrome and 59 age-matched patients (control group) were enrolled in this prospective study. Serum homocysteine levels were compared between the 2 groups. We compared the estimated 10-year risk of coronary heart disease based on Framingham risk score between the 2 groups. Additionally, we analyzed correlations between risk of coronary heart disease and serum homocysteine levels. RESULTS: The mean homocysteine level of patients with pseudoexfoliation syndrome was significantly higher than the control group (13.3 ± 6.8 µmol/L vs. 10.0 ± 5.2 µmol/L, p = 0.009). The rate of high risk defined as a 10-year coronary heart disease risk >20% in the patients with pseudoexfoliation syndrome was significantly higher than in the control group (21.4% vs. 4.4%, p = 0.048). Correlation between serum homocysteine levels and estimated 10-year risk of coronary heart disease was statistically significant (r = 0.578, p < 0.001). CONCLUSIONS: Hyperhomocysteinemia and high risk of coronary heart disease were observed in patients with pseudoexfoliation syndrome. Therefore, we suggest efforts to prevent coronary heart disease in pseudoexfoliation syndrome patients with hyperhomocysteinemia are necessary.
