RESUMEN
Development and comparison of the latent fingerprints (LFPs) are two major studies in detection and identification of LFPs, respectively. However, integrated research studies on both fluorescent materials for LFP development and digital-processing programs for LFP comparison are scarcely seen in the literature. In this work, highly efficient red-emissive carbon dots (R-CDs) are synthesized in one pot and mixed with starch to form R-CDs/starch phosphors. Such phosphors are comparable with various substrates and suitable for the typical powder dusting method to develop LFPs. The fluorescence images of the developed LFPs are handled with an artificial intelligence program. For the optimal sample, this program presents an excellent matching score of 93%, indicating that the developed sample has very high similarity with the standard control. Our results are significantly better than the benchmark obtained by the traditional method, and thus, both the R-CDs/starch phosphors and the digital processing program fit well for the practical applications.
RESUMEN
The aim of the present study was to analyze risk factors of intestinal perforation following surgery for the treatment of congenital heart disease in infants and young children, and to summarize experiences of diagnosis and treatment. A total of 3,270 children, who underwent congenital heart disease surgery under extracorporeal circulation from January 2010 to July 2015, were retrospectively analyzed. Among these children, three (0.09%) developed postoperative intestinal perforation. Primary diseases were Tetralogy of Fallot (two cases) and ventricular septal defect combined with atrial septal defect (one case). The age range of the children was 6-11 months and the weight range was 7.3-8.6 kg. Furthermore, these children underwent radical surgery under general anesthesia and extracorporeal circulation in low temperatures. Abdominal symptoms appeared 4-10 days after surgery, and included poor appetite, abdominal distension, intermittent vomiting, high fever, refractory irritability, crying and shortness of breath. One case was confirmed by routine abdominal puncture and the remaining two were confirmed by the detection of free gas under the diaphragm, as revealed by abdominal X-ray. Following the diagnosis of intestinal perforation, emergency intestinal fistula surgery was performed. At 3-5 days post-surgery, the patients underwent treatment by fasting and intravenously administered parenteral nutrition. Diet was increased following recovery of bowel function. All patients recovered following active treatment and 3-4 months following hospital discharge, the fistula was successfully closed. In conclusion, a concerted effort should be made to identify intestinal perforation in infants and young children with postoperative congenital heart disease during emergency surgery. Early diagnosis and treatment may significantly improve prognosis and reduce mortality.
RESUMEN
OBJECTIVE: To study the feasibility of interphase fluorescence in situ hybridization (FISH) in detection of chromosomal aneuploidy in touch preparations of lung carcinoma and its clinic significance. METHODS: We examined 46 touch preparations of lung carcinomas by FISH with DNA specific for chromosomes 7, 8, 9 and 12 to detect chromosomal aneuploidy. RESULTS: Aneuploidy, mainly featured in gains of chromosomes 7, 8 and 12 and loss of chromosome 9 were observed in all of the touch preparations of the 46 cases with lung cancer. The rates of chromosomal aneuploidy detected by FISH were 67.4% (31/46), 60.9% (28/46), 28.3% (13/46) and 56.5% (26/31) respectively. CONCLUSION: Interphase FISH is feasible in detecting aneuploidy in touch preparations of lung cancer. These alterations may be applied to early diagnosis and predicting prognosis of lung cancer.
