Objective:To investigate the association of renal insufficiency and clinical outcomes in patients with acute coronary syndrome(ACS). Methods: The study was a multi-centre register study including 3 589 ACS patients coming from 39 centers across China who had received percutaneous coronary intervention(PCI) prior to 1st February, 2007. Estimated glomerular filtration rate (eGFR) was calculated for all patients using the 4-variable MDRD equation with the serum creatinine obtained before angiography. The association between renal insufficiency and clinical outcomes and the presence of in-hospital death and bleeding was studied by Fisher’s exact test. Multi-variable analysis on the risk factors of in-hospital bleeding was done by logistic regression test. Results: The mean age of the study population was (61.74?11.37) years (ranging from 23 years to 92 years)and 76.5% (2 746/3 589) of the population was male. Only 90 patients (2.51%) were known to have chronic kidney disease at the time of admission and 144 patients(4.01%) had serum creatintine levels above 133 ?mol/L. However, after the evaluation of renal status by the MDRD equation, 2 250 patients (63.1%)showed a reduction in eGFR of less than 90 mL/min, of whom, 472 (13.1%) even reached the level of moderate renal insufficiency (eGFR

In 21th century, percutaneous coronary intervention (PCI) technique enters in rapid development stage in China. From 2009, quality control system of PCI runs in national scale. Since then, the national quality control center estab?lished cooperative relationship with the provincial quality control centers. Official website and quality control tools were im?proved. PCI data were collected and analyzed annually, and then reported to the regulatory body and published to the public. Audit was run irregularly. Quality control centers were also involved in some other related affairs such as training course and admission. The quality control system lead PCI in China to an improved daily practice and control PCI application all overthe country in terms of data. In the future, the quality control techniques and teamwork will be further improved. And quality evaluation system and management team will be perfected gradually. Quality control will be extended from PCI to coronary heart disease and combined with audit of coronary heart disease. According to the quality control data, the quality and its rank of medical centers will be published in certain range. So that we can provide better care to the coronary heart disease pa?tients.

Objective To investigate the anti-proliferation effect of triptolide-eluting stent, as well as its effectiveress, dose-effect relationship and safety. Methods Experimental stents were divided into 4 groups with 10 stents each, namely bare stent group, sirolimus-coated stent group, 5.6 ?g triptolide-coated stent group and 56 ?g triptolide-coated stent group. By morphometric and histopathologic analysis,we compared 5.6 ?g and 56 ?g triptolide-eluting stents with bare metal stents and sirolimus-eluting stents 28 days after stenting in rabbit iliac models of restenosis. Results The neointimal area of 5.6 ?g triptolide-eluting stents was similar to that of bare metal stents, but larger than that of sirolimus-eluting stents. The neointimal area of 56 ?g triptolide-eluting stents was smaller than that of bare metal stents and 5.6 ?g triptolide-eluting stents, but was similar to that of sirolimus-eluting stents. In all the groups, proliferation on both edges of the stents was insignificant. No toxic effect had been found in the experimental animals related to triptolide-eluting stent. Conclusion Triptolide-eluting stents may inhibit neointimal proliferation. The effect of inhibiting neointimal proliferation is dose dependent and with no adverse effect. These results suggest that triptolide-eluting stent can prevent restenosis within four weeks.

Objective To analyze the clinical features of vasovagal syncope, enhance its clinial awareness and to promote the importance of history taking in the differential diagnosis of syncope. Methods A total of 83 patients with the diagnosis of vasovagal syncope were included in the study and their data were, undergone retrospective statistical analysis. Results A 63.9% of patients had recurrent syncope. There was 73.5% of them had motivation and 80.7% of them had presyncope symptoms. Complete loss of consciousness was found in 77.1% of patients. There was 39.1% of them had concomitant symptoms and 39.1% had postsyncopal symptoms. In 54.2% of the patients the duration of syncope was less than 2 minutes. Conclusion It is important to pay attention to history taking and to anylaze the clinical features in the diagnosis of vasovagal syncope.
