Chinese Journal of cardiovascular Rehabilitation Medicine 2015;24(1):1-5
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 observe the role of vascular endothelium growth factor (VEGF) in promoting vascular reconstruction and bone repair in the necrotic region of femoral head in rabbits. Methods The femoral head necrosis model was made by liquid nitrogen frozen. The necrotic femoral head was transfected by adenovirus human VEGF121 (Ad-hVEGF121) to observe the bone formation in subchondral necrotic region by means of histological method, measure BMD value by SPA-2 analyser and measure bone trabecular morphology by image analysis. Results Revascularization level, bone formation rate, bone quality and quantity and mineralization level in subchondral necrotic region of gene transfection group were significantly higher than the control groups that had more subchondral bone resorption compared with gene transfection group. Conclusions VEGF may have effect in promoting bone formation and revascularization in subchondral necrotic region of femoral head, indirectly protecting the necrotic bone trabecula from being absorbed and avoiding descending of subchondral mechanics function.

Objective To investigate the effects of propofol and inhalation anesthetics on the implicit memory under general anesthesia and determine the critical value of auditory evoked potential index (AEI) at which implicit memory no longer exists. Methods Sixty ASA I-II patients of both sexes scheduled for elective abdominal surgery or surgery on lower limb were enrolled in the study. They averaged (41.25?9.25) years and (63.8?9.57) kg. Patients with psychoneural or memory disorders were excluded. The patients were randomly divided into five groups of 12 patients in each group: isoflurane, sevoflurane, desflurane, propofol and control group. Each inhalation anesthetic group was further divided into two subgroups based on their end-tidal concentration: 0.8 or 1 .0 MAC. Propofol group was divided into two groups based on the infusion rate: 8 mg.kg. h-1 or 10mg.kg.h-1 . In control group operation was performed under epidural anesthesia. The patients were unpremedicated. Anesthesia was induced with propofot 1 .5-2.0 mg.kg and vecuronium 0. -0.2mg.kg-1, and maintained with inhalation anesthetic or propofol infusion supplemented with intermittent boluses of fentanyl and vecuronium. AEI was continuously monitored and recorded before anesthesia (T0), when the patient was sleepy (T1 ) and did not respond to verbal command (T2 ), after intubation (T3), after skin incision (T4), when peritoneum was being closed (or 30 min before the surgery) ( T5 ) and during emergence from anesthesia ( T6 ) . Eight hours after surgery muddy identified hearing rate was determined. Hemodynamic parameters were continuously monitored during operation. Results There was significant difference in AEI between the two subgroups before and after induction (P
