ObjectiveTo examine the relationship between ankle brachial index (ABI) and the extent of coronary stenosis and evaluate the usefulness of ABI to predict the extent of coronary stenosis in old patients.Methods118 patients with coronary angiography were examined by ABI and hemostatic factors evaluation in addition to history collection.ResultsABI was inversely and significantly associated with Gensini score. ABI reduced significantly (P<0.001) in the patients with 3-vessel or left main coronary artery disease (CAD). But there were no significant differences in ABI among the patients with no CAD, 1-vessel or 2-vessel CAD. The corresponding area under the ROC curve was 0.75±0.045, with 95% CI=0.67～0.84 (P<0.001) in ABI in 3-vessel or left main CAD. When ABI≤0.9, it had a relatively high specificity (89.1%) and sensitivity (55.6%) for predicting the presence of 3-vessel disease or left main CAD.ConclusionIn the old patients, ABI is inversely and significantly associated with the extent of coronary stenosis, and ABI≤0.9 has a relatively high specificity and sensitivity for predicting the presence of 3-vessel or left main CAD.

Synergetic effects for p-nitrophenol degradation were observed in the ozonation with ultrasonic enhancement. The enhancements of removal rate for p-nitrophenol and TOC were around 116% and 294% respectively in comparison with the individual ultrasound and ozonation systems. The synergetic phenomenon is attributed to two physicochemical mechanisms: (1)Ultrasound decomposes ozone causing augmentation of the activity of free radicals; (2) Ultrasonic wave increased the concentration of O3 in solution because of ultrasonic dispersion.

OBJECTIVETo analyze the CT image characteristics of liver secondary lymphoma.

METHODSThe medical records of 13 patients were reviewed. There were 12 non-Hodgkin lymphoma cases and 1 Hodgkin lymphoma case. Abdomen CT scan was performed in all cases, plain scan and enhanced CT scan were performed in 11 cases, plain CT scan was performed in 2 cases.

RESULTSOf the 13 cases, 11 were nodular type, 1 was diffuse type, and 1 was mixed type. Plain CT scan showed low density, enhanced CT showed circular enhancement in 1 case, mild to midrange delayed enhancement in 1 case, midrange enhancement in 1 case, mild enhancement in 2 cases, blood vessel floating sign in 3 cases, no enhancement in 6 cases.

CONCLUSIONSThe characteristics of liver secondary lymphoma CT image of liver secondary lymphoma includes blood vessel floating sign and enhancement.

OBJECTIVETo evaluate the clinical therapeutic effect of Compound Paeonol Dripping Pill (CPDP) and its effect on the levels of plasma inflammatory mediators, including C-reactive protein (CRP), interleukin-6 (IL-6), tumor necrosis factor-alpha (TNF-alpha) and monocyte chemotactic protein-1 (MCP-1).

METHODSNinety patients with unstable angina were randomized by enveloping method into 3 groups equally, the conventional Western therapy group (A), the CPDP group (B), and the Tongxinluo group (C). The improvement of angina pectoris symptoms and electrocardiogram (ECG) was observed after 2 weeks of treatment and the levels of plasma CRP, IL-6, TNF-alpha and MCP-1 were measured before and after treatment.

RESULTSThe total effective rate in improving angina pectoris was 93.3% in Group B, significantly higher than that in Group A (73.3%, P <0.01) and Group C (76.7%, P <0.05), while no significant difference of ECG improvement rate was found between the three groups (P >0.05). Plasma total cholesterol and inflammation indexes were significantly lowered after treatment in Group B (P <0.05), showing a significant difference to those in the other two groups (P <0.05), but the indexes were unchanged in the other two groups (P >0.05).

CONCLUSIONEffect of CPDP is better in relieving symptoms, depressing inflammatory reaction for treatment of unstable angina patients than that of Tonxinluo Capsule and conventional Western treatment.

BACKGROUNDBrachial-ankle pulse wave velocity (baPWV) is a reliable method for measuring arterial elasticity, but the absence of reference value for baPWV has limited its wide use. We conducted an epidemical study in north China to investigate the reference value of baPWV for Chinese people and its influential factors.

METHODSA total of 974 identified healthy subjects were recruited in this study. The values of baPWV were evaluated noninvasively with an automatic device.

RESULTSFor healthy population, the mean value of baPWV was higher for male (P < 0.001). Multiple regression analysis demonstrated that both age and systolic blood pressure were positively associated with baPWV for male and female (P < 0.001). BaPWV value was higher in male than in female in younger group (< 50 years) but not in older group (P

CONCLUSIONSAging is the most important reason of arterial stiffness, but the effect of age on baPWV augmentation is greater for healthy female than their male counterpart. The reference values of baPWV by sex and age are very useful for clinical and preventive medicine.

Objective To compare the efficacy and safety between cryoablation (Cryo) and radiofrequency (RF) ablation for treating patients with atrioventricular nodal reentrant tachycardia (AVNRT). Methods Patients with AVNRT (n=304) were divided into Cryo group (n=67) and RF group (n=237). The procedure success rate, complete slow pathway block rate, atrioventricular block rate and relapse rate were compared between two groups. Results There was no statistically difference between 2 groups in the success rate (Cryo group 98.5% vs RF group 97.0%, P=0.820), complete slow pathway block rate (Cryo group 98.5% vs RF group 91.6%, P=0.088), atrioventricular block rate (Cryo group 0 vs RF group 2.5%, P=0.413), relapse rate (Cryo group 0 vs RF group 1.7%, P=0.643). But Cryo group had more advantage than RF group. Conclusion Efficacy and safety were comparable between cryoablation and radiofrequency ablation for treating patients with AVNRT.

OBJECTIVETo evaluate protective effects of Rheum tanguticum polysaccharides (RTP) on traumatic brain injury (TBI) in rats.

METHODThe polysaccharides (RTP) were extracted from Tanguficum Maxim. 120 rats were divided into 15 groups, with 8 rats in each group. RTP at 100, 200 and 400 mg x kg(-1) were administrated orally once a day for five days, and model of brain injury was made by dropping weight method.

RESULTRTP reduced water content and malondialdehyde (MDA) levels, and increased total SOD activity and Na+-K+ ATPase activity after injuried.

CONCLUSIONThe polysaccharides may be one of the effective comptents in Rheum tanguticum, showing significant neuroprotective effects.

BACKGROUNDTo find the pathogenic agents of aseptic meningitis prevalent in Xuzhou of Jiangsu province in 2001.

METHODSThe enterovirus (EV) was cultured from CSF of the patients and identified with anti-serum by neutralization test. Neutralization titer of antibody in paired sera from meningitis children was determined. EV RNA was detected by RT-PCR.
