Objective: To explore change of heart rate turbulence (HRT) in patients with coronary artery disease (CAD) and its predictive value. Methods: A total of 58 CAD patients were regard as CAD group. The 50 normal persons with negative CAG were regard as normal control group. All subjects received 24h dynamic ECG, CAG and echocardiography examination. Left ventricular ejection fraction (LVEF) and HRT indexes were compared between two groups. Results: Compared with normal control group, there was significant rise in turbulence onset [TO, (-1.34±1.09)% vs. (2.32±0.60)%] and significant reduction in turbulence slope [TS, (11.14±2.27) ms/RR vs. (3.44±0.60)ms/RR] in CAD group, P<0.01 both; in CAD group, along with coronary artery lesion aggravated (single-, double-, multi-vessel coronary disease), there was significant rise in TO [(1.35±0.52)% vs. (2.56±0.83)% vs. (3.01±1.62)%] and significant reduction in TS [(6.49±1.79) ms/RR vs. (3.33±1.02) ms/RR vs. (1.66±0.30) ms/RR], the difference was significant in two-two comparison among all groups, P<0.05 or <0.01; compared with CAD without cardiac event group, there was significant rise in TO [(1.68±0.61)% vs. (2.24±0.24)%], and significant reduction in TS [(5.87±1.22) ms/RR vs. (1.65±0.23) ms/RR] and LVEF[(66.18±2.64)% vs. (56.36±3.34)%] in CAD with cardiac event group, P<0.01 all. Conclusion: Weakened HRT phenomenon exists in CAD patients. HRT can be treated as an index evaluating severity of CAD patients’ condition and an effective predicting index for recurrent cardiac events in CAD patients.

Objective To evaluate the values of diagnosis in anomalies of aortic valve with transesophogeal echocardiography (TEE) before operation. Methods Thirty-seven cases of anomalies of aortic valve which were diagnosed by TEE and treated by operation were analyzed retrospectively, the features of anomalies of aortic valve, pattern of cardiac structure changing and the reference values of diagnosis with TEE in choosing correct operation method were summarized. Results There were different characteristics in the number of valve and juncture, location of juncture, opening and closing shape of aortic valve, aortic valvular stenosis, aortic valvular regurgitation or both of them.Pattern of changes of cardiac structure included ascending aorta dilatation, left ventricle enlarge and left ventricle hypertrophy. Features of aortic valve anomalies and pattern of changes of cardiac structure were the important consulting information for the selection of operation method. Conclusion TEE is an important diagnosis method for anomalies of aortic valve, and it can provide abundant and valuable information for choosing an appropriate operational method.

OBJECTIVE:To provide new identification method for processed medicinal material Chinese polyphaga(Eupolyph-aga sinensis,Steleophaga plancyi) and their adulterants by establishing molecular identification method based on Cytb genes. METHODS:The total DNA of Chinese polyphaga and their adulterants was extracted using modified saturation sodium chloride method. The Cytb genes of all samples were amplified with PCR using general primers REVCB2H and REVCBJ. The phylogenetic tree of all samples was constructed with Neighbor-Joining(NJ)method using MEGA 5.1 software. The sequences of the Cytb gene of all sampled were compared by using DNAMAN sofetware. The difference between genuine product and their adulterants were analyzed,and the specific primers Esin-F and Esin-R were designed for molecular identification in different regions. RESULTS:DNA extracted from processed medicinal insects was successful to amplify Cytb gene segments. The phylogenetic tree of all sam-ples was consistent with their genetic relationship. A fragment was amplified only from genuine product but not from other adulter-ants with the designed specific primers Esin-F and Esin-R. CONCLUSIONS:DNA extraction method from processed Chinese polyphaga and their adulterants have been established. Designed specific primers are highly specific to genuine product Chinese polyphaga,and can be used for the identification of Chinese polyphaga and their adulterants.

Objective To detect the mutation of A379,we develop a TaqMan fluorogenic probe based amplification refractory mutation system (TaqMan-ARMS) and investigate whether the A379V variant and activity of Lp-PLA2 are the risk factors for CAD.Methods According to the amplification refractory mutation system(ARMS-PCR)combined with a TaqMan fluorogenic probe,we established and evaluated the assay teehnique of TaqMan-ARMS for measuring the genotype of variant.At the same time,we tested the aetivity of Lp-PLA2 in 395 patients with coronary heartdisease and 396 controls,whose clinical information [ages,CHO,GLU,TG,HDL,LDL,Hs-CRP,Lp (a)] were collected.Date was analyzed by using Independent-samples t test,Chi-square test,One-Way ANOVA,Binary Logistic Regression.Results CAD group had significantly higher Lp-PLA2 activity than the controls(31.51 nmol · ml-1 · min-1 ＞21.31 nmol ·ml-1 · min-1,F =16.40,P ＜ 0.001).Comparing the highest quartile of Lp-PLA2 activitv to the bottom quartile,OR was 7.50 (95％ CI:2.34-24.05) after adjustment for various traditional cardiovascular risk factors,including ages,sex,CHO,TG,Hs-CRP,Lp (a) and GLU; the genotype VV of A379V was associated with higher risk of CAD (OR =2.95; 95％ CI:1.22-7.15,P ＜ 0.05).Conclusions The TaqMan-ARMS real time PCR technique is established to analyze A379V genotype.Lp-PLA2 activity is significantly higher in CAD group and is a risk factor for CAD; the genotype VV of A379V is also a risk factor for CAD.
