Objective To assess the safety and efficacy of transcatheter closure of congenital coronary artery fistulas(CAFs).Methods Retrospective analysis was performed on 19 patients mean age of(5.5?4.1) years treated from February 1995 to December 2005 with transcatheter closure of CAFs using transcatheter spring coil embolization,Amplatzer PDA occluder or Amplatzer plug.One case had a residul fistula postoperatively associated with patent duetus arteriosus(PDA).Results The abnormal parameters included mean fistula diameter(3.7?1.6)mm(2.5-8.2 mm),pulmonary mean pressure(28.0?5.0)mmHg(25.0-67.0 mmHg)and pulmonary to systemic shunt(Qp/Qs)1,6?0.8(1.0-2.3).The sites of the fistulas were originated in right coronary artery 11,left anterior descending coronary artery or left circumflex coronary artery 8. Abnormal communication sites of these fistulas were to right ventricle in 14 and right atrium in 5.Various occlusion devices used to close these fistulas included one Giantureo coil in 10,2-4 Gianturco coils in 3, Duct-Occlud in 3,Amplatzer duct occluder in 2 and Amplatzer plug in 1.The post-operative residul fistula with PDA was treated successfully with PDA occlusion.The immediate,one month and one year complete occlusion rates were 55.6%(10/18),88.9%(16/18),100%(18/18),respectively.The coil slipped into the left pulmonary artery in 1 case and correction was obtained by retrieving with forceps.Follow-up studies at 3 months to 4.3 years showed complete abolition of shunt in all patients with no evidence of recanalization leading to recurrences of shunt.Conclusion Transcatheter closure of CAFs is a safe and effective alternative to surgical repair.

Objective To investigate the relationship between atherosclerotic lesions of arteries of lower extremities and metabolic disorders in patients with diabetic foot. Methods Three hundreds and sixty two patients with type 2 diabetes were selected, including 232 males and 130 females, with average age of (64.9?11.2) years and the average diabetic duration of (9.2?7.5) years. Atherosclerotic lesions of the arteries were detected by type B ultrasound. According to severity of lesions of femoral, popliteal and tibial arteries, the patients were classified into four groups: A-control group, B-plague formation (plague), C-arterial stenosis (stenosis) (luminal narrowing≥50%) and D-arterial occlusion (occlusion). Fasting blood glucose, GHbAlc and lipid levels (Total cholesteral, TC; Triglyceride, TG; Low density iipoprotein, LDL) were tested in all patients. Results (1)GHbAlc levels in group B and group C were significantly different from that in group A respectively[(8.4?2.2%)vs(7.8?2.2%),P

Objective To establish UV spectrophotometry and HPLC methods for content determinations of total flavonoids and puerarin from Puerariae Lobatae Radix and Puerariae Thomsonii Radix; To compare the ultrasonic method at room temperature, conventional refluxing method and ultrasonic method at heating conditions at the aspect of content determinations.

OBJECTIVETo explore the pathogenesis of tumors by blocking the normal differentiation process of stem cells.

METHODSBone marrow mesenchymal stem cells (BMSCs) from rats were isolated, cultured and purified by whole bone marrow adherence method. The rat BMSCs were induced to differentiate into adipocytes with dexamethasone, insulin and indomethacin. Blockage of the differentiation process was induced by 3-methylcholanthrene (3-MC).

RESULTSThe differentiation experiment showed that at 30 days after the induction, oil red O staining-positive cells occurred with increased intracytolasmic lipid droplets, characteristic for adipocytes. The differentiation blockage experiment showed that at 30 days after induction, the deposits of oil red O staining-cytoplasmic lipid droplets was significantly reduced, indicating that the blocked cells were adipocytes, but not fully differentiated. Morphological identification showed that cell contact inhibition disappeared, abnormal cell nuclei, increased number of micronucleus aberration and karyotype abnormalities, indicating that malignant transformation of the stem cells occurred after the differentiation blockage.

CONCLUSIONSThe results of this study show a blockage of the differentiation of that stem cells at the intermediate phase, and a tendency of malignant transformation of the stem cells. The results of our study provide new evidence that cancer stem cells may be originated by suppression of stem cell differentiation.
