Abstract Introduction: This study investigated the correlation between the levels of long noncoding ribonucleic acids (lncRNAs) AF131217.1 and coronary slow flow (CSF). Methods: A total of 22 patients in the high-sensitivity C-reactive protein (hsCRP) group diagnosed with CSF from January 2018 to December 2018 were enrolled in this study. Coronary flow velocity was determined using the thrombolysis in myocardial infarction frame count (TFC) method. Results: LncRNA AF131217.1 expression in the CSF model was activated. Mean TFC was positively correlated with lncRNA AF131217.1 levels and hsCRP levels. LncRNA AF131217.1 induced inflammation factor levels in the in vitro model. Micro ribonucleic acid (miR)-128-3p is a target spot of lncRNA AF131217.1 on the inflammation in vitro model via Kruppel-like factor (KLF) 4. MiR-128-3p reduced inflammation factor levels (tumor necrosis factor alpha, interleukin [IL]-6, IL-1β, and IL-18). Conclusion: Thus, lncRNA AF131217.1 promoted inflammation in the regulated CSF via KLF4 by miR-128-3p. Introduction lncRNAs (lncRNAs AF1312171 AF AF131217 1 AF131217. CSF. .

ABSTRACT Purpose: To evaluate the impact of one-time high load exercise on skeletal muscle injury and analysis its mechanism in different genders. Methods: Twenty-four male and 24 female rats were divided randomly into four groups respectively: control, 0 h, 6 h, and 24 h after exercise. The activities of creatine kinase (CK), lactate dehydrogenase (LDH), and myohemoglobin (MYO) in serum, the expression level of oxidative stress markers, mitochondrial respiratory chain complex enzyme, and the apoptosis related protein in quadriceps were detected. Results: The results showed that the activities of CK, LDH and MYO in serum increased immediately after exercise and restored faster in female rats. More obvious structural disorder and apoptosis in male rats were showed. Malondialdehyde (MDA) and superoxide dismutase (SOD) were increased while catalase (CAT) and glutathione (GSH) were decreased in male rats. SOD, CAT and GSH were increased in female rats. Mitochondrial complex enzyme activity was decreased in males and increased in females. Conclusions: The skeletal muscle injury in both genders of rat could be induced by one-time high load exercise due to the mitochondrial respiratory enzyme dysfunction and oxidative stress, which was relatively mild and recovered quicker in female rats.

OBJECTIVES: To explore the effect of tumor and normal lung volumes on lung volume-dose parameters in patients with non-small-cell lung cancer (NSCLC) who had undergone intensity-modulated radiation therapy (IMRT). METHODS: The clinical data of 208 patients with NSCLC who underwent radical IMRT between June 2014 and June 2018 were retrospectively analyzed. A regression model curve was used to evaluate the effect of tumor and normal lung volumes on normal lung relative volumes receiving greater than 5 and 20 Gy (V5, V20), on mean lung dose (MLD), and on absolute volumes spared from greater than 5 and 20 Gy (AVS5, AVS20). RESULTS: The V5, V20, and MLD of the bilateral lung were fitted to a quadratic equation curve with the change in tumor volume, which increased initially and then decreased when the tumor volume increased. The V5, V20, and MLD of the lung reached their apex when the tumor volumes were 288.07, 341.69, and 326.83 cm3, respectively. AVS5 and AVS20 decreased in a logarithmic curve with an increase in tumor volume. The V5, V20, and MLD of the small normal lung volume group were all significantly higher than those of the large normal lung volume group (p<0.001, p=0.004, p=0.002). However, the AVS5 and AVS20 of the small normal lung volume group were all significantly lower than those of the large normal lung volume group (p<0.001). CONCLUSION: The effects of tumor volume and normal lung volume on dose-volume parameters should be considered. AVS5 is an important supplementary dose limitation parameter for patients whose tumor volume exceeds a certain boundary value (approximately 300 cm3).

The effect of heat treatment on the microstructures and tensile properties of a powder metallurgical (PM) TiAl based alloy has been investigated in this paper. The near gamma (NG) microstructure is transformed to a full lamellar (FL) microstructure with an average grain size of 100 μm by heat treatments. The lamellar spacing of FL structure decreases with the increase of cooling rate. For cooling rates of 5, 10 and 50 °C/min, the lamellar spacing is 1.9, 1.0 and 0.8 μm respectively. The room temperature tensile properties exhibit an increasing trend with decrease of lamellar spacing.

OBJECTIVE: To evaluate changes in the age-adjusted prevalence of disability in transitional China from 1987 to 2006. METHODS: Data from nationally representative surveys conducted in 1987 and 2006 were used to calculate age-adjusted disability prevalence rates by applying appropriate sample weights and directly adjusting to the age distribution of the 1990 Chinese population. Trends were assessed in terms of average annual percentage change. FINDINGS: The estimated number of disabled people in China in 1987 and 2006 was 52.7 and 84.6 million, respectively, corresponding to a weighted prevalence of 4.9% and 6.5%. The age-adjusted prevalence of disability decreased by an average of 0.5% per year (average annual percentage change, AAPC: -0.5%; 95% confidence interval, CI: -0.7 to -0.4) during 1987-2006. However, it increased by an average of 0.3% (AAPC: 0.3%; 95% CI: 0.1 to 0.5) per year in males and by an average of 1.0% (AAPC: 1.0%; 95% CI: 0.8 to 1.2) per year among rural residents, whereas among females it showed an average annual decrease of 1.5% (AAPC: -1.5%; 95% CI: -1.7 to -1.3) and among urban residents, an average annual decrease of 3.9% (AAPC: -3.9%; 95% CI: -4.3 to -3.5). Despite significant declining trends for hearing and speech, intellectual and visual disabilities, the annual age-adjusted prevalence of physical and mental disabilities increased by an average of 11.2% (AAPC: 11.2%; 95% CI: 10.5 to 11.9) and 13.3% (AAPC: 13.3%; 95% CI: 10.7 to 16.2), respectively. CONCLUSION: In China, the age-adjusted prevalence of disability has declined since 1987, with inconsistencies dependent on the type of disability. These findings call for continuing and specific efforts to prevent disabilities in China.

OBJETIVO: Evaluar los cambios en la prevalencia de discapacidad ajustada por edad en la China de la transición desde 1987 hasta 2006. MÉTODOS: Se utilizaron datos de sondeos representativos a nivel nacional realizados en 1987 y 2006 para calcular las tasas de prevalencia de discapacidad ajustada por edad mediante la aplicación de los tamaños de muestra adecuados y mediante el ajuste directo de la distribución por edades de la población china en 1990. Las tendencias se evaluaron en función del porcentaje promedio anual de cambio. HALLAZGOS: El número estimado de personas discapacitadas en China en 1987 y 2006 era de 52,7 y 84,6 millones, respectivamente, lo que a su vez se corresponde con una prevalencia ponderada del 4,9% y del 6,5%. En promedio, la prevalencia de discapacidad ajustada por edad se redujo en un 0,5% al año (porcentaje promedio anual de cambio, PPAC: -0,5%; intervalo de confianza del 95%, IC: de -0,7 a -0,4) de 1987 a 2006. No obstante, en promedio ha presentado un incremento del 0,3% (PPAC: 0,3%; IC del 95%: de 0,1 a 0,5) al año en varones y el promedio ha sido del 1,0% (PPAC: 1,0%; IC del 95%: de 0,8 a 1,2) al año en residentes en áreas rurales, mientras que en mujeres se observó una reducción anual media del 1,5% (PPAC: -1.5%; CI del 95%: de -1,7 a -1,3) y en residentes en áreas urbanas la reducción anual media observada fue del 3,9% (PPAC: -3,9%; CI del 95%: de -4,3 a -3,5). A pesar de que las tendencias muestran un descenso significativo de las discapacidades auditivas, del habla, intelectuales y visuales, la prevalencia de discapacidad anual ajustada por edad de las discapacidades físicas y mentales aumentó, en promedio, el 11,2% (PPAC: 11,2%; IC del 95%: de 10,5 a 11,9) y 13,3% (PPAC: 13,3%; IC del 95%: de 10,7 a 16,2), respectivamente. CONCLUSIÓN: En China, la prevalencia de discapacidad ajustada por edad ha disminuido desde 1987, si bien se encuentran ciertas contradicciones entre los tipos de discapacidad. Estos resultados destacan la necesidad de contar con iniciativas continuas y concretas para prevenir las discapacidades en China.

OBJECTIF: Evaluer les changements dans la prévalence de l'invalidité en fonction de l'âge dans la Chine en transition de 1987 à 2006. MÉTHODE: Des données provenant d'études représentatives sur le plan national menées en 1987 et en 2006 ont été utilisées pour calculer le taux de prévalence de l'invalidité en fonction de l'âge, en appliquant des échantillons appropriés et en ajustant directement la répartition de l'âge de la population chinoise en 1990. Les tendances ont été évaluées en termes de modification du pourcentage annuel moyen. RÉSULTATS: On a estimé à respectivement 52,7 millions et 84,6 millions le nombre de personnes invalides en Chine en 1987 et en 2006, ce qui correspond à une prévalence pondérée de 4,9% et de 6,5%. La prévalence de l'invalidité en fonction de l'âge a diminué d'en moyenne 0,5% par an (modification du pourcentage annuel moyen, MPAM: 0,5%; intervalle de confiance à 95%, IC: -0,7 à -0,4) entre 1987 et 2006. Il a toutefois augmenté d'en moyenne 0,3% (MPAM: 0,3%; IC 95%: 0,1 à 0,5) par an chez les hommes et d'en moyenne 1%; IC 95%: 0,8 à 1,2) par an parmi les résidents ruraux, alors qu'il présentait, parmi les femmes une diminution annuelle moyenne de 1,5% (MPAM: 1,5%; IC 95%: -1,7 à -1,3) et parmi les résidents urbains, une diminution annuelle moyenne de 3,9% (MPAM: -4,3 à -3,5). En dépit de tendances déclinantes significatives pour l'audition et la parole et pour les incapacités intellectuelles et visuelles, la prévalence annuelle en fonction de l'âge des invalidités physiques et mentales a augmenté d'en moyenne 11,2% (MPAM: 11,2%; IC 95%: 10,5 à 11,9) et 13,3% (MPAM: 13,3%; IC 95%: 10,7 à 16,2), respectivement. CONCLUSION: En Chine, la prévalence de l'invalidité en fonction de l'âge a décliné depuis 1987, avec des incohérences en fonction du type d'invalidité. Ces conclusions invitent à poursuivre des efforts ciblés en vue de prévenir les invalidités en Chine.
