Objective To explore whether depressive disorder is one of risk factors for coronary artery disease (CAD) in enrolled patients and observe the level of inflammation markers in coronary artery disease patients with depression. Methods In all patients, we recoded clinical information and data from Hamilton Depression Rating Scale for Depression( HRSD)and measured concentration of monocyte chemoattractant protein-1 (MCP-1), tumour necrosis factor α (TNFα) and hypersensitive C-reaction protein (hsCRP). Results Among 87 patients with coronary artery disease, depressive disorder was diagnosed in 26 patients, the prevalence of depressive disorder was 29. 9%. Among 101 patients without coronary artery disease, 12 patients were suffering from depressive disorder, the prevalence of depressive disorder was 11.90%. The prevalence of depressive disorder in coronary artery disease group was statistically higher than that in non-coronary heart disease group (29.8% vs.11.9%, P<0. 01). The incidence of coronary artery disease was associated with age, hypertension,diabetes mellitus, hypercholesterolemia and depression. Life events and stage of heart function occurred differently between CAD patients with and without depression (P<0. 05). There were no differences in the degree of coronary artery stenosis and the type of treatment (P>0. 05) between the two groups. There were higher concentration of MCP-1 in coronary artery disease patients with depression, but no remarkable difference in hsCRP and TNFa.Conclusions There is high prevalence of depressive disorder, which is one of risk factor for coronary artery disease. The depressive disorder may be associated with inflammation biomarker in patients with coronary artery disease.

BACKGROUND: Clinical experiments indicates that Yufeng capsule (composed of milkvetch root, angelica, szechwan lovage rhizome, senega and salvia miltiorrhiza) is effective for benefiting vital energy, circulating blood flow,dispelling gores and killing inflammation. The mechanism may be associated with the function of platelet aggregation, changes of contents of thromboxane B (TXB) and 6-Ketoprostaglandin F1 alpha (6-keto-PGF1 α) in plasma.OBJECTIVE: To observe the influence of Yufeng capsule on the platelet aggregation and its mechanism.DESIGN: Randomized controlled animal trial.SETTING: Department of Pathology, Daqing Branch of Harbin Medical University.MATERIALS: The experiment was performed at the Laboratory of Pharmacology, Daqing Branch of Harbin Medical University from May 2000 to July 2004. A total of 40 Wistar male gerontic rats with mean age of (8-10) weeks and mean body mass of (550±150) g and 8 Wistar male young rats with mean age of 4-6 weeks and mean body mass of (230±120) g were selected.METHODS: The 8 Wistar male youth rats were selected as youth control group. The 40 Wistar male gerontic rats were selected as the blood stasis model, and according to the numeration table method they were classified into 5 groups: aspirin group, low-dose Yufeng capsule group, the middle-dose Yufeng capsule group, high-dose Yufeng capsule group and gerontic model group, with 8 rats in each group. The Yufeng capsule was constituted by milkvetch root, angelica, szechwan lovage rhizome, senega and salvia miltiorrhiza, and provided by the Preparation Office, Second Affiliated Hospital,Heilongjiang University of Chinese Medicine. Respectively the rats were injected with aspirin solution (5.5 g/kg), Yufeng capsule (0.33 g/kg, 0.66 g/kg and 1.32 g/kg), successively for 22 days by gastric perfusion, twice a day.Those in the gerontic group and youth control group were not treated with any drug One hour after last time administration, function of platelet aggregation(PAG), contents of thromboxane B2 (TXB2) and 6-Ketoprostaglandin F1 alpha (6-keto-PGF1 α) in plasma were examined with platelet aggregation method and radioimmunoassay.MAIN OUTCOME MEASURES: Function of platelet aggregation; contents of TXB2 and 6-keto-PGF1 α as well as ratio of TXB2 to 6-keto-PGF1α.RESULTS: Totally 48 animals were involved in the result analysis. ①The PAG was higher in the gerontic model group than other groups (P < 0.01).②One minute platelet aggregation rate (PAG1), five minutes platelet aggregation rate (PAG5)and the maximal platelet aggregation rate (PAGM) in the high-dose Yufeng capsule group were lower than those in the aspirin group[(7.96±2.17), (6.38±1.66), (14.33±2.87) ng/L and (31.95±3.94),(35.29±6.54), (38.68±7.46) ng/L, respectively(P < 0.01 )]. PAG5 in the middle-dose group was lower than that in the aspirin group [(13.96±1.66),(35.29±6.54) ng/L, (P < 0.01 )]. ③TXB2 content in the low-dose Yufengcapsule group, middle-dose Yufeng capsule group, high-dose Yufeng capsule group, aspirin group and youth control group was lower than that in the gerontic model group (P < 0.01). ④The TXB2 content in the high-dose Yufeng capsule group was lower than that in the low-dose Yufeng capsule group [( 100.13±8.90), (127.00±20.99) ng/L, (P < 0.01 )]. ⑤TXB2/6-ke-to-PGF1 α in the high-dose Yufeng capsule group, middle-dose Yufeng capsule group and youth control group was lower than that in the gerontic model group [0.62±0.17,0.69±0.14,1.75±0.17,1.11±1.12, (P < 0.05 )].CONCLUSION: High-dose and middle-dose Yufeng capsule is able to decrease the content of TXB2 and increase the content of 6-keto-PGF1 α, and improve their ratio. It is important to enhance the balance of TXB2 and 6-keto-PGF1 α. The effect in the low-dose Yufeng capsule group is lower as compared with that in the high-dose and middle-dose Yufeng capsule groups. It is thought that the low-dose Yufeng capsule has preventive effect.
