Objective To evaluate the feasibility, and clinical efficacy of combined interventional procedure (CIP) in composite cardiovascular diseases (CCD). Methods Twenty one consecutive patients were diagnosed as CCD before the procedures. The algorithm of CIP were individualized by the operators and physicians. The criteria for a successful procedure were defined before the operation. The counterplan for predictable complications was also established beforehand. The successful rate, short and long term efficacy, the incidence of complications and adverse reaction associated with contrast medium and X-ray were observed. All the patients were followed up through special out-patient clinic, telephone, or letters. Results Seven cases accepted electrophysiological testing(EPT) + radiofrequency catheter ablation (RFCA)+coronary angiogram (CAG)+percutaneous transluminal coronary angioplasty (PTCA)+stent implantation (SI). Four cases accepted CAG+PTCA+SI+EPT. Three cases accepted EPT+RFCA+CAG. Six cases accepted CAG+PTCA+SI+peripheral artery angiogram (PAG). One cases accepted pacemaker implantation (PI)+CAG+PTCA+SI+percutaneous transluminal septal myocardial ablation (PTSMA). The symptoms of arrhythmia disappeared or alleviater in 19 cases during hospiatalization. Arrhythmia recurred in 2 cases 12 hours after the procedure and accepted RFCA again. No severe complications and adverse reaction occured. The successful rate was 90.5 percent. Two cases suffered from recurrent angina during the follow-up period and one of them had in-stent restenosis proved by CAG and accepted PTCA+SI again. The other patient received medicine therapy. Conclusion Combined interventional procedure operated by experienced interventional cardiologist in a conditioned catheterization laboratory is safe and feasible. The short-term outcomes are satisfied. The long-term outcomes will be proved by accumulating more cases' data. Individualized approaches, counterplans for complications and cautious operation are important to a successful procedure.

Objective To study the separation ability of AB-8 macroporous resin in the purification of arctinin in Fructus arctii. Methods HPLC was used to measure the content of arctinin, and the adsorption performance and the elution parameters were investigated. Results The optimal separation conditions were as follows: the concentration of Arctinin was 5.5 mg/ml with a flow rate of 2 BV/h, and 50% alcohol was used as eluant. The adsorption of Arctinin was 52.08 mg/g, and the elution ratio of arctinin was 93.8%, and the purity of arctinin reached 65.2%. Conclusion AB-8 resin can be used to refine the arctinin in the extraction of Fructus arctii.

Objective To explore the effect of aerobic exercise on platelet function in elderly patients with hypertension and type 2 diabetes.Methods81 elderly patients with hypertension and type 2 diabetes were divided into the routine treatment group (group A, n=41) and regular exercise group (group B, n=40). All patients of two groups were treated with routine treatment. The exercise with moderate intensity was performed in the group B for 3 months besides routine treatment. The platelet membrane glycoprotein CD62P, CD61 (Ⅲa) were detected by flow cytometric analysis and platelet aggregating ratio was measured before and after regular aerobic exercise.ResultsAfter three months, the systolic blood pressures were 166±3.6 mm Hg (group A) and 152±3.5 mm Hg (group B); the diastolic blood pressures were 93±4.2 mm Hg (group A) and 83±4.3 mm Hg (group B); the contents of blood glucose were 7.4±2.4 mmol/L (group A) and 6.3±1.9 mmol/L (group B); the positive percents of platelet membrane glycoproten CD62P were 27.3±2.2% (group A) and 21.5±3.3% (group B), CD61(Ⅲa) were 26.3±2.3% (group A) and 20.2±2.9% (group B) and platelet aggregation rates were 78.4±4.5% (group A) and 69.7±5.4% (group B), there was a significant difference between two groups ( P<0.05～0.01).ConclusionRegular aerobic exercise can decrease the positive percent of platelet membrane glycoprotein and platelet aggregation rate in elderly patients with hypertension and type 2 diabetes.

Objective To observe the therapeutic effects of the co-administration of γ-aminobutyric acid (CABA), sodium dimercaptopropane sulfonate (Na-DMPS) and vitamin B6 in large doses on liver and heart of rats with acute tetramine intoxication, and compare their separate effects of either GABA or Na-DMPS alone with those of the triad combination. Method Thirty rats were randomized into control group (n = 6), tetramine intoxication without treatment group (n = 6), tetramine intoxication treated with GABA group (n = 6), tetramine intoxication treated with Na-DMPS group (n = 6) and tetramine intoxication treated with triad combination (GABA + Na-DMPS + vitamin B6, GNDV n = 6) group. Samples of blood, liver tissue and heart tissue of rats with acute tetramine intoxication were collected immediately two hours after medication with different drugs. Serum alanine aminotrasferase (ALT), aspartate aminotransferase (AST), creatine kinase (CK) and creatine kinase isoenzyme (CK-MB) were measured, and the pathological changes of liver tissue and heart tissue were observed under microscope. Results The symptoms of poisoning were apparently relieved and the latency for convulsion/muscular twitch were obviously delayed in poisoned rats treated with GABA, Na-DMPS and GNDV separately. Furthermore, combination group showed the latent period delayed longer than either GABA or Na-DMPS groups The GABA, Na-DMPS and GNDV significantly lowered the serum levels of ALT, AST, CK and CK-MB in rats with tetramine intoxication, and those serum levels of enzymes were lower in GNDV group than those in either GABA group or Na-DMPS group. However, there were no difference in those serum enzymes between GABA group and Na-DMPS group. Moreover, the intoxicated rats treated with combination treatment had the slightest pathological changes in liver and heart (GNDV < GABA or Na-DMPS). Conclusions The co-administration of γ-aminobutyric acid, sodium demercaptopropane sulfonate and vitamin B6 in large doses for the treatment of tetramine intoxication is a method of choice.

Objective To evaluate the angiographic findings and the therapeutic effect of thrombolysis in AMI (acute myocardial infarction) patients. Method A retrospective study were carried out in consecutive eighty-four inpatients with AMI treated with intravenous thrombolysis and coronary angiography was taken within a week after illness onset from January 2000 to August 2007. The patients were divided into successful recanalization group and non-recanalization group. Single factor χ2 test and multi-factor logistic regression analysis were applied to observe the relationship among the angiographic features of IRA (infarct-related artery including the number of stnosis, the location of stenosis, the severity of stenosis and the morphological changes) and treatment effect of intravenous urokinase thrombolysis. Results (1) Single factor χ2 test showed that location and the extent of lesion of IRA were eligible to enter the logistic regression formula (P ＜ 0.05),whereas the number of lesions and the severity of IRA's stenosis were not eligible to enter the logistic regression formula (P ＞ 0. 05). (2) Multi-factor logistic regression analysis showed that the extent of lesion of IRA was the only factor that had a negative impact on the therapeutic effect of intravenous thrombolysis.Conclusions The study shows that the extent of lesion of IRA is the only factor that has a negative impact on the therapeutic effect of intravenous thrombolysis; The number, the location of lesion and the severity of stenosis of IRA have no impact on the therapeutic effect of intravenous thrombolysis in AMI.

Background and Objectives The relationship between left atrial (LA) size and congestive heart failure (CHF) is well recognized;however, there is little information on the association of pulmonary vein (PV) diameter and CHF.The purpose of this study was to investigate the changes of PV and LA sizes in CHF patients by multislice computed tomography (MSCT) angiography using a new 64-slice scanner. Methods and Results We assessed diameters of PVs ostium and LA by 64-slice MSCT with three-dimensional reconstruction in 25 CHF patients and in 26 age- and sex-matched non-CHF controls. Compared with controls, CHF patients showed significant greater diameters of left superior pulmonary vein (LSPV) and right inferior pulmonary vein (RIPV) in both anteriorposterior(AP) and superior-inferior (SI) directions (P＜0.01), significant dilation of right superior pulmonary vein (RSPV) in AP direction (P＜0.05), as well as significant increase of LA transverse, AP, and SI diameters (P＜0.01). Conclusion Significant dilation of PVs with simultaneous LA enlargement was demonstrated in CHF patients. This anatomic and geometric changes may participate in the perpetuation of AF.

Objective To determine whether sleep-disordered breathing (SDB) may lead to nocturnal myocardial ischemia and whether the severity of this ischemia may be relieved by nasal continuous positive airway pressure (CPAP). Methods Overnight polysomnogram examination and simultaneous 3-channel Holter monitoring were performed on 76 patients with moderate to severe SDB and no history of coronary heart disease. All the cases were treated with CPAP for one night. ST depression was defined as a ST segment decrease of more than 1 mm from baseline and lasting 1 min or more. The total duration (minutes) of ST depression was indexed to the total sleep time (minutes per hour of sleep). Results Twenty-eight patients (37%) showed ST segment depression during their sleep. Before CPAP treatment, the respiratory disturbance index (RDI) and arousal index were significantly higher during periods of ST depression than when ST segments were isoelectric, whereas no significant difference was found in blood oxygen saturation (SaO2). After the CPAP treatment of patients with ST depression, the duration of ST depression was significantly reduced from 36.8±18.9 to 11.4±13.2 min/h (P＜0.05). ST depression-related indexes, including RDI, arousal index and the percentage of sleep time spent at SaO2 below 90% (TS90/ TST), were all significantly decreased, with RDI from 63.4±23.8 to 8.1±6.6 /h, arousal index from 51.2±18.9 to 9.6±5.4 /h, and TS90/ TST from 50.6±21.4 to 12.9±14.7% (P＜0.05). Conclusion ST-segment depression is rather common in patients with moderate to severe SDB, and CPAP treatment can significantly reduce the duration of ST depression. ST depression in these patients may reflect the myocardial ischemia that really exists and the non-ischemic changes associated with recurrent SDB.
