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.
4.Effect of compound paeonol dripping pill on levels of plasma inflammatory mediators in patients with unstable angina.
Chinese Journal of Integrated Traditional and Western Medicine 2008;28(5):395-398
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 summarize the effects and complications of osteosarcoma around knee treated by wide resection and replacement by the tumor-type prosthesis.
METHODSBetween July 1997 and July 2004, 117 patients with osteosarcoma around the knee had been treated with wide resection and reconstruction with prosthesis. Alcohol-devitalized tumor bone prosthetic composite were used for reconstruction in 13 patients, and allograft prosthetic composite (APC) were used in 25 patients. All patients accepted 2 cycles of chemotherapy before the surgery.
RESULTSThe mean follow-up period was 3.5 years (1 - 8 years). Nine patients had failure of union at the graft-host junction. Fracture of the stem of the prosthesis occurred in 5 patients, late infection was found in 19 patients, and aseptic loosening occurred in 3 patients. Bone fracture occurred in 1 patient and prosthesis sinking occurred in 2 patients.
CONCLUSIONSThe tumor-type prosthetic reconstruction offers the best knee function after resection of the tumor around the knee, and recurrence rate can be accepted. However, the tumor-type prosthesis needs further improvement because of the high complication rate.

The methods to determine the total phenols, total saponins, and marker constituents salidroside, chlorogenic acid and 3, 4-dihydroxy-phenylethyl-β-D-glucopyranoside in the samples of Sargentodoxae Caulis were established to provide the evidence for the improvement and revision of the quality standard of the crude material recorded in the Chinese Pharmacopoeia (2015 Edition). The content of total phenols was determined by ultraviolet spectrophotometry, using gallic acid as a reference substance. The content of total saponins was determined by ultraviolet spectrophotometry, using 3-O-[β-D-xylopyranosyl-(1-2)-O-β-D-glucuronopyranosyl]-28-O-[β-D-glucopyranosyl] asiatic acid as a reference substance. The contents of salidroside, chlorogenic acid and 3,4-dihydroxy-phenylethyl-β-D-glucopyranoside were detected by HPLC. The linear ranges were 1.01-7.04 mg x L(-1) for total phenols, 37.7-201 μg for total saponins, 0.025 8-1.55 μg for salidroside, 0.076 2-5.44 μg for chlorogenic acid, and 0.064 9-3.47 μg for 3,4-dihydroxy-phenylethyl-βP-D-glucopyranoside, respectively. Their average recoveries were 99.12%, 99.11% 105.5%, 99.08%, and 101.6%, respectively. The contents of total phenols and total saponins were 3. 04% -11. 9% and 0. 87% -3. 63%. The contents of salidroside, chlorogenic acid and 3,4-dihydroxy-phenylethyl-β-D-glucopyranoside fluctuated from 0.018% to 0. 572%, from 0.041% to 1.75% and from 0.035% to 1.32%. The established methods were reproducible, and they could be used for the quality control of Sargentodoxae Caulis. The present investigation suggested that total phenols, salidroside, and chlorogenic acid should be recorded in the quality standard of Sargentodoxae Caulis and their contents should not be less than 6.8% for total phenols, 0.040% for salidroside, and 0.21% for chlorogenic acid.
