ABSTRACT
Objective: To observe the short- and long-term clinical outcomes of fraction flow reserve (FFR)-guided percutaneous coronary intervention (PCI) in coronary artery disease (CAD) patients with SYNTAX score≥33 unsuitable for coronary artery bypass grafting (CABG). Methods: A total of 117 CAD patients admitted in our hospital from 2012-01 to 2015-06 were enrolled. Since SYNTAX score≥33, EuroSCORE>6, the patients were unsuitable for CABG and treated in 2 groups: Medication group, n=20 and PCI group, during FFR-guided PCI procedure, patients received ROTA or IVUS according to physician's experience, n=97. All patients were followed-up for at least 12 months. Meanwhile, taking "coronary stent and bypass", "CABG and PCI" as key words, we searched relevant documents in VIP Chinese science and technology journal full-text database, WanFang medical database, ChinaNet and Chinese biomedical literature database from 2012-01-01 to 2015-12-31, patients' outcomes were compared with the above references to explore the clinical benefit. Results: ① PCI group and Medication group had similar SYNTAX score and EuroSCORE, P>0.05. The common pathogenesis was LAD involvement, chronic occlusion was 31.3% (5/16) in patients with partial revascularization.②PCI group had 18.6% (18/97) incidence of major adverse cardiac and cerebral events (MACCE), 2 patients died during follow-up period and 9 received revascularization; Medication group had 60% (12/20) incidence of MACCE, 3 patients died during follow-up period; the difference between 2 groups showed statistical meaning, P<0.05.③There were 22 relevant documents retrieved as comparison; in our research, PCI group had similar incidence of MACCE to the documents, P>0.05; Medication group had increased incidence of MACCE than the documents, P<0.05. Conclusion: FFR-guided PCI could bring clinical benefit in CAD patients with SYNTAX score≥33 unsuitable for CABG.
ABSTRACT
<p><b>OBJECTIVE</b>Gastroenteritis is a major cause of childhood morbidity and mortality worldwide. Adenovirus AdV is recognized to be one of the most important pathogens associated with severe dehydrating gastroenteritis. Studies reported elsewhere have shown that about 8%-10% of cases with infantile diarrhea are caused by AdV and in some areas AdV diarrhea even occurred in the form of outbreaks. Studies have confirmed that AdV infections are also very common in infants and young children in China. This study aimed to investigate the molecular epidemiologic characteristics of human adenovirus diarrhea among infants and children with acute diarrhea in Lanzhou, Gansu province, China.</p><p><b>METHOD</b>Stool specimen and case information were collected from both outpatients and inpatients with acute diarrhea in Lanzhou. Polymerase chain reaction was used to detect AdV in stool specimens. The subjects included 709 urban children and 180 rural children, their age ranged from 19 d to 60 months.</p><p><b>RESULT</b>Of the 889 cases, 43 (4.8%) were found positive for AdV. AdV was detected in 14 of 257 (5.4%) cases seen from July 2005 to June 2006, in 4 of 286 cases (1.4%) seen from July 2006 to June 2007. During the period of July 2007 to June 2008, adenovirus was detected in 346 specimens, the positive rate was 7.2% (25/346). AdV detection rates of the three-year period were significantly different. The major AdV subtypes detected were adenovirus (subgenus F) Ad40, Ad41 with a positive rate of 3.8% (34/889), followed by non-enteric adenovirus (Ad12, Ad18, Ad31, Ad2, Ad5, Ad6, Ad7) with a positive rate of 1.0% (9/889) in Lanzhou during the 3 years. Most of the AdV-positive specimens showed Ad41 group F (67.4%, 29/43) as the major epidemic strains, and Ade infection mainly occurred in children under one year of age and no seasonal cluster was found.</p><p><b>CONCLUSION</b>Adenovirus was one of the major etiological agent of viral diarrhea among infants and children in Lanzhou between 2005 and 2008. Ad41 was the prodomiment serotype.</p>
