RESUMEN

Objective@#To analyze diagnosis rate of chronic kidney disease (CKD) in hospitalized pediatric patients in a single center and understand pediatricians′ awareness of CKD.@*Methods@#This was a cross-sectional study. Children who were admitted to the Division of Pediatric Nephrology, Peking University First Hospital from January 1, 2008 to December 31, 2017 and met the diagnostic criteria of CKD (kidney disease: improving global outcomes 2012 guideline) were recruited. A total of 4 472 cases were enrolled. Original CKD diagnosis was collected from the home page of medical records. Actual CKD diagnosis was validated and corrected by reviewing medical records and recalculating glomerular filtration rate. The diagnosis rate and influencing factors of pediatric CKD, the distribution and etiology of actual CKD were analyzed. The comparison between groups were performed with χ2 test.@*Results@#In 4 472 cases, there were 3 470 cases in actual CKD stage 1, among which only 24 cases were in original CKD stage 1. There were 543 cases in actual CKD stage 2-3, among which only 181 cases were in original CKD stage 2-3. Three hundred and one cases were in actual CKD stage 4-5, including 290 cases in original CKD stage 4-5. In addition, there were 43 cases with unknown CKD stage and 115 cases with acute kidney injury. Compared to original CKD diagnosis, the diagnosis rates of CKD stage 1-5 were 0.7% (24/3 470), 16.7% (58/348), 63.1% (123/195), 90.7% (78/86) and 98.6% (212/215), respectively. The proportions of actual CKD stage 1-5 were 80.4% (3 470/4 314), 8.1% (348/4 314), 4.5% (195/4 314), 2.0% (86/4 314) and 5.0% (215/4 314). The etiology of actual CKD included primary glomerular disease (62.2%, 2 686/4 314), secondary glomerular disease (19.7%, 849/4 314), hereditary kidney disease (9.1%, 391/4 314), congenital abnormalities of the kidney and urinary tract (CAKUT) (3.1%, 135/4 314), tubulointerstitial disease (2.2%, 94/4 314) and etiology uncertain (2.1%, 89/4 314). The leading cause of end stage renal disease was etiology uncertain (31.1%, 67/215), followed by hereditary kidney disease (24.2%, 52/215), CAKUT (16.3%, 35/215) and primary glomerular disease (16.3%, 35/215).@*Conclusions@#Among actual CKD hospitalized pediatric patients, the diagnosis rate of CKD given by physicians at discharge was relatively low, especially patients in earlier CKD stages, which reflected serious lack of physicians′ awareness of CKD.

RESUMEN

Objective To preliminary formulated 2017 Chinese rare disease survey list by experts consensus.Methods By using checklist methods,we selected studied diseases from five available rare disease data sources in China.By summarizing,proofreading,removing of duplicate data,the primary survey list with 344 diseases was formulated.By organizing two rounds of consensus conferences,experts voted and revised the survey list,then ultimately formulated 2017 Chinese rare disease survey list.Results According to the poll,in selected 344 rare diseases which were discussed in consensus conferences,54 diseases were suggested to be deleted,9 pairs of diseases were suggested to be incorporated.For Chinese and English names of these rare diseases,306/344 diseases conform to nomenclature by discussion.According to the experts' tips and advice,we revised the primary survey list and ultimately formulated 2017 Chinese rare disease survey list including 281 diseases.Conclusions Experts consensus combines the scientificity of methodology and clinical experience of experts.In the background of medical big data and targeted poverty alleviation,the early stage of study is in accordance with the main stream of thought for the national survey of rate disease in China.

RESUMEN

With the rapid development of cardiac pacing therapy,the number of pacemakers used in children is growing.Children grow fast,with small size and thin wall heart wall.Underlying diseases in children are different from those in adults.As a result,it is quite important to choose proper electrode,pulse generator,pa-cing site and carry out regular follow-up.Epicardial electrodes are usually used in infants,while endocardial ones have been the leading choice due to long lifespan,minimal injury and stable threshold.Many studies indicate that right ventricular pacing can damage left ventricular function and left ventricular pacing is more physiological.It is essential to remove the entire pacemaker system once the diagnosis of pocket infection is made.Elevation of pacemaker threshold and electrode-related complications are more common in epicardial pacemakers while ve-nous occlusion and tricuspid regurgitation are more common in endocardial pacemakers.In recent years,there is progress in remote monitoring system,cardiac resynchronization therapy,magnetic resonance imaging pacemak-ers and leadless pacemakers,which might be promising therapies in the near future.

RESUMEN

Objective To explore the effect of CD40 small interfering RNA(siRNA)on the expressions of pe-ripheral blood interleukin(IL)-21 and IL -35 in rats with experimental autoimmune myocarditis (EAM)and its sig-nificance.Methods Twenty 6 -8 week male Lewis rats were divided into normal group,EAMgroup,CD40 siRNA group and siRNA group by using random number table,with 5 rats in each group.The normal rats were induced with phos-phate buffer saline in double foot pads on day 0 and day 7,while the rest 3 groups were induced with cardiac myosin protein to establish EAMmodels.The rats in CD40 siRNA group and siRNA group were respectively injected with CD40 siRNA and siRNA slow virus expression vector through the tail vein of rats on day 7.The rats were executed on 21 day after echocardiogram examination was made.The histopathologic changes were observed by using light microscope and the myocardial histopathology scores were calculated.Enzyme -linked immunosorbent assay was used to determine the levels of IL -21 and IL -35 in peripheral blood.Results (1)Except the normal group,the total incidence rate of rats of each group was 100%,and there was no rat death.(2)Compared with EAM group,the heart mass/body ratio and myocardial histopathology scores were lower in CD40 siRNA group,and the differences were significant (3.13 ±0.21 vs 3.80 ±0.29,2.22 ±0.43 vs 3.32 ±0.51,F =0.332,0.456,all P <0.05).(3)The echocardiogram showed that there was only 1 rat in EAM group with massive pericardial effusion,and there was no pericardial effusion in CD40 siRNA group.EAMgroup,CD40 siRNA group and siRNA group displayed hypertrophy of the ventricular septum and left ventricular wall,narrow heart cavity and weakening of ventricular wall motion.The left ventricular shortening rate in CD40 siRNA group was significantly higher than that in the EAMgroup[(63.34 ±11.06)% vs (38.56 ±6.98)%,F =16.080,P <0.05].(4)The peripheral blood level of IL -21 in CD40 siRNA group was lower than that in EAM group [(141.19 ±17.46)ng/L vs (157.81 ±17.58)ng/L,F =57.008,P <0.05],while its level of IL -35 was signifi-cantly higher than that in the EAMgroup [(195.96 ±18.26)ng/L vs (174.78 ±13.91 )ng/L,F =31.727,P <0.05].(5)The level of IL -21 in peripheral blood was positively correlated with myocardial histopathology scores in EAM group (r = 0.69,P < 0.05 ),but IL -35 was negatively correlated with myocardial histopathology scores (r =-0.64,P <0.05).Conclusions CD40 siRNA might relieve the myocardial inflammation and reduce the myocar-dial injury of EAMrats.The levels of IL -21 and IL -35 can partly reflect the degree of myocardial injury.The mecha-nism may be related to down -regulating the expression IL -21 and up -regulating the expression of IL -35.
