RESUMEN

RNAs are involved in the crucial processes of disease progression and have emerged as powerful therapeutic targets and diagnostic biomarkers. However, efficient delivery of therapeutic RNA to the targeted location and precise detection of RNA markers remains challenging. Recently, more and more attention has been paid to applying nucleic acid nanoassemblies in diagnosing and treating. Due to the flexibility and deformability of nucleic acids, the nanoassemblies could be fabricated with different shapes and structures. With hybridization, nucleic acid nanoassemblies, including DNA and RNA nanostructures, can be applied to enhance RNA therapeutics and diagnosis. This review briefly introduces the construction and properties of different nucleic acid nanoassemblies and their applications for RNA therapy and diagnosis and makes further prospects for their development.

RESUMEN

Nursing becoming a respectable, decent profession for educated Chinese women was a challenging undertaking. The early advancement of nursing in China was a collective effort of the missionary medicine, the private foundations, and the endurance, dedication and hardworking of the Chinese as well as foreign nurses. Western missionary introduced modern nursing in China and laid the preliminary foundation for its development, while the upgrading of nursing education from training to higher learning was a contribution by the School of Nursing Peking Union Medical College (PUMC), envisioned and supported by the China Medical Board. Its state-of-the-art and visionary education model, the high standard and the initiatives in public health nursing, and the heroic and patriotic military nursing created by the PUMC's outstanding graduates produced a cohort of leaders in nursing education and profession in China before 1949. All these efforts acting together shaped the modern nursing in China, leaving a great heritage to nursing education and practice to New China.

RESUMEN

Objective To investigate the association and difference between patent foramen ovale(PFO), atrial septal aneurysm(ASA), atrial septal defect(ASD) in normal controls and cryptogenic ischemic stroke(CS) in youth diagnosed by double source CT.Methods A total of 168 CS patients and 180 controls matched age and gender were included in the present study.The two groups were diagnosed by double source CT and clinical materials.The incident rate of PFO, ASA, ASD, the degrees of PFO, ASD,the lengths of PFO and difference between CS in two groups were analysed.Results The incident rates of PFO, ASA, ASD were 40.6%,10.7%,6.5% and 15.6%,3.3%,2.2% in CS groups and controls respectively(P0.001).Conclusion PFO,ASA and ASD are important to CS.While PFO,ASA and ASD can accurately be diagnosed by double source CT.

RESUMEN

MicroRNAs (miRNAs) play vital roles in diverse biological processes, including in immune response. Blunt snout bream (Megalobrama amblycephala) is a prevalent and important commercial endemic freshwater fish species in China's intensive polyculture systems. To identify immune-related miRNAs of M. amblycephala, two small RNA (sRNA) libraries from immune tissues with or without lipopolysaccharide (LPS) stimulation were constructed and sequenced using the high-throughput sequencing technology. Totally, 16,425,543 and 15,076,813 raw reads, corresponding to 14,156,755 and 13,445,869 clean reads, were obtained in the normal and infected libraries, respectively. A total of 324 miRNAs, including 218 known miRNAs and 106 putative novel miRNAs were identified by bioinformatic analysis. We analyzed differentially expressed miRNAs between two libraries using pairwise comparison. 113 (34.88%) miRNAs were found to be significantly differentially expressed between two libraries, with 63 (55.75%) exhibiting elevated expression in LPS stimulation sample. Thereinto, a number of known miRNAs were identified immune-related. Real-time quantitative PCR (RT-qPCR) were implemented for 12 miRNAs of two samples, and agreement was confirmed between the sequencing and RT-qPCR data. Target genes likely regulated by these differentially expressed miRNAs were predicted using computational prediction. The functional annotation of target genes by Gene Ontology enrichment (GO) and Kyoto Encyclopedia of Genes and Genomes pathway analysis (KEGG) indicated that a majority of differential miRNAs might involved in immune response. To our knowledge, this is the first comprehensive study of miRNAs in response to LPS stimulation in M. amblycephala, even in fish. These results deepened our understanding of the role of miRNAs in the intricate host's immune system, and should be useful to develop new control strategies for host immune defense against various bacterial invasions in M. amblycephala.

Objective To investigate the clinical and laboratory feature of neonatal hemolytic disease (HDN)occurred in Qingdao caused by mother-baby ABO blood type disagreement.Methods Serum bilirubin (TBIL)test and micro column gel technology were used on 422 cases neonatal hemolytic disease children blood samples (collected from Jun.2013 to Feb.2015).Results There were 388 cases first-born children among 422 cases including 206 cases of type A and 216 of type B and the difference between them was not statistically significant (χ2 =0.24,P >0.05).The difference between male (218 cases)and female (204 cases)was not statistically significant (χ2 =0.24,P >0.05)too.The indirect bilirubin (IBI)increas-ing was more obviously.The peak level of serum bilirubin was 116~465 μmol/L and 256.5~342.0 μmol/L was 38.9% (χ2=0.24,P >0.05).162 cases reticulocyte count was increased nearly 38.5% (χ2 =75.62,P <0.05).RBC antibody release test and serum free antibody test were often positive and the percentage was 80.1% (χ2 =146.98,P <0.05).Conclusion The neonatal hemolytic disease may turn up in first-born children.The child with three positive test was more sensitive to neonatal hyperbilirubinemia.RBC antibody release test and serum free antibody test are often positive.It is important to make the early diagnosis and treatment as soon as possible for reducing the bilirubin encephalopathy.

RESUMEN

Objective To explore the hereditary susceptibility of children with asthma through studying the relationship between erythroeyte CR1 genomic density polymorphism and erythrocyte immune function. Methods The rates of RBC-C3_(3b)RR and RBC-ICRR were detected to the asthma group consisted of 65 children with asthma and the control group consisted of 28 normal children. The CR1 activity and genomic density polymorphism of erythrocyte from the two groups were detected by Hind Ⅲ restriction enzyme digestion, polymerase chain reaction restriction fragment length polymorphism. Results Frequencies of high expression gene (HH), mid expression gene (HL) and low expression gene (LL) genotypes were 43.08% (28/65), 36.92% (24/65) and 20.00% (13/65) in asthma group, and 78.57% (22/28), 17.86% (5/28) and 3.57%(1/28) in control group respectively. A significant difference was found in the distribution frequency of CR1 genotype between the two groups(P< 0.01).The rates of RBC-C_(3b)RR were significant lower and the rates of RBC-ICRR were significant higher in asthma group than those in control group (P < 0.01). The rates of RBC-C_(3b) RR in HH, HL and LL were decreased in order (P < 0.01),while the rates of RBC-ICRR in HH,HL and LL were increased in order (P < 0.01). Conclusion It suggests that CR1 gene polymorphism may play an important role in determining susceptibility to asthma.
