RESUMO À medida que a vida das pessoas se torna melhor, cada vez mais cidadãos já não se contentam com problemas simples como comida e vestuário, mas, gradualmente, passam a cuidar da vida espiritual que anseiam. Nesse contexto, a saúde física é também um fator importante. Então, nesse estágio, muita gente passa a fazer natação para exercitar o corpo e a mente. Neste artigo, utilizou-se o algoritmo de integração, além da capacidade de autoaprendizagem do algoritmo. Utilizou-se o algoritmo para estudar o modelo de postura na natação, que pode desempenhar um papel importante no ensino da tradicional postura de natação.

ABSTRACT As people’s lives become better and better, more and more citizens are no longer satisfied with simple food-and-clothing problems, but gradually move towards the spiritual life they are yearning for. Among this, physical health is also an important part of it. So, at this stage, a lot of people will go swimming to exercise their body and mind. In this paper, the integration algorithm was used, and the self-learning ability of the integration algorithm was used. This algorithm was used to study the swimming posture model. This model can play an important role in the teaching of traditional swimming posture.

En ese contexto, la salud física es también un fator importante. Entonces, en ese nivel, mucha gente comienza a hacer natación para ejercitar el cuerpo y la mente. En este artículo, se utilizó el algoritmo de integración, además de la capacidad de autoaprendizaje del algoritmo. Se utilizó el algoritmo para estudiar el modelo de postura en la natación, que puede desempeñar un papel importante en la enseñanza de la tradicional postura de natación.

OBJECTIVES: To explore the clinical significance and correlation of microRNA-21 (miR-21) and the neutrophil-lymphocyte ratio (NLR) in patients with acute myocardial infarction (AMI). METHODS: The observation group contained 184 patients, while the control group contained 150 patients. The expression of miR-21 in the serum of each group was detected by qRT-PCR. RESULTS: A total of 184 patients and their family members were followed-up for 30 days, among which 35 patients died and 149 patients survived, resulting in a survival rate of 80.97%. According to univariate analysis, there were significant differences in age, cardiac troponin (cTn), heart rate, Killip grade, percutaneous coronary intervention (PCI) operation rate, miR-21 and NLR. In the receiver operating characteristic (ROC) analysis, the area under the curve (AUC) values of miR-21 and NLR for the diagnosis of AMI were 0.909 and 0.868, respectively, and the area under the combined detection curve was 0.960. In the Kaplan-Meier survival analysis, the survival of patients with high miR-21 expression and NLR was significantly higher than that of patients with low miR-21 expression and NLR (p=0.027; p=0.001). The correlation showed that miR-21 expression in serum was positively correlated with the NLR in the observation group (r=0.528, p<0.05). cTn, heart rate, Killip classification, PCI operation rate, miR-21, NLR are independent risk factors for AMI. CONCLUSION: miR-21 and NLR play a role in the diagnosis of AMI and can be used as predictors for the survival of AMI.

The Vasa protein is a member of the DEAD (Asp-Glu-Alu-Asp) box family of ATP-dependent RNA helicases. The Vasa gene is specifically expressed in germ-line cells of many metazoans and is known to play a critical role in gametogenesis and reproductive regulation. In this paper, we isolate the full length cDNA sequence of the Vasa gene from the frog Rana nigromaculata Hallowell, 1861. The open reading frame (ORF) encoding 398 amino acid residues has nine conserved motifs. According to the similarities at the amino acid sequenceythe phylogenetic analysis of Vasa gene was consistent with the evolution relationships from chordates to mammals. Furthermore, the expression pattern analysis of RnVasa mRNA, using the technique of Reverse Transcriptase-Polymerase Chain Reaction (RT-PCR), showed a high level of transcripts in testis, ovary and kidney, whereas little to no signal was detected in other tissues, which suggests that it may play a role during gametogenesis.
