Abstract Background and purpose: the Dietary Approaches to Stop Hypertension (DASH) diet has multifunctional health benefits. We evaluated the effects of low-sodium salt applied to Chinese modified DASH diet on arterial stiffness in older patients with hypertension and type 2 diabetes. Methods: sixty-one older adults with hypertension and type 2 diabetes were randomly allocated to low sodium salt group (n = 31) or normal sodium salt group (n = 30). They were given the Chinese modified DASH diet plus low-sodium salt (52 % sodium chloride) or same diet plus regular salt (99 % sodium chloride) for eight weeks, respectively. Brachial and ankle pulse wave conduction velocity, ankle brachial index and atherosclerosis-related indices were measured at baseline and week 8. In addition, 24-hour urine and blood samples were measured at baseline, the 4th week and the end of the intervention. Results: as compared with the baseline, the low sodium salt group significantly decreased in ankle brachial index (-0.09 ± 0.11, p < 0.001) and brachial and ankle pulse wave conduction velocity (-133.07 ± 265.99 cm/s, p = 0.010) at week 8 while the normal sodium salt group only decreased significantly in ankle brachial index (-0.06 ± 0.12, p = 0.010) at week 8. Conclusion: the low-sodium salt applied to Chinese modified DASH diet may improve arterial stiffness in patients with hypertension and type 2 diabetes. Further research with an extended follow-up is needed.

Resumen Antecedentes y propósito: la dieta DASH (del inglés Dietary Approaches to Stop Hypertension) tiene beneficios multifuncionales para la salud. Evaluamos los efectos de una sal baja en sodio aplicada a la versión modificada china de la dieta DASH sobre la rigidez arterial en pacientes mayores con hipertensión y diabetes tipo 2. Métodos: sesenta y un adultos mayores con hipertensión arterial y diabetes tipo 2 fueron asignados al azar al grupo de sal baja en sodio (n = 31) o al grupo de sal con contenido normal de sodio (n = 30). Se les administró la versión china modificada de la dieta DASH más sal baja en sodio (52 % de cloruro de sodio) o la misma dieta más sal con la cantidad normal de sodio (99 % cloruro de sodio) durante ocho semanas, respectivamente. Se midieron la velocidad de onda de pulso brazo-tobillo, el índice brazo-tobillo y los índices relacionados con la aterosclerosis al inicio del estudio y a la semana 8. Se recogieron muestras de orina y sangre de 24 horas al inicio, a la cuarta semana y al final de la intervención. Resultados: en comparación con el estado inicial, el grupo de sal baja en sodio disminuyó significativamente el índice brazo-tobillo (-0,09 ± 0,11, p < 0,001) y la velocidad de onda de pulso brazo-tobillo (-133,07 ± 265,99 cm/s, p = 0,010) en la semana 8, mientras que el grupo de sal con contenido normal de sodio solo disminuyó significativamente en el índice brazo-tobillo (-0,06 ± 0,12, p = 0,010) en la semana 8. Conclusión: la sal baja en sodio aplicada a la versión china modificada de la dieta DASH puede mejorar la rigidez arterial en pacientes con hipertensión y diabetes tipo 2. Se necesitan más investigaciones con un seguimiento prolongado.

Abstract Introduction: hypertension and diabetes are chronic disorders associated with an increased risk of cardiovascular disease. Objectives: to evaluate the effect of 52 % low-sodium salt applied to the Chinese-modified DASH (CM-DASH) diet on risk of atherosclerotic cardiovascular disease (ASCVD) in patients with hypertension and type-2 diabetes. Methods: the low-sodium salt group (LSSG) took 5 g/day of 52 % low-sodium salt plus CM-DASH diet for 8 weeks, while the normal-sodium salt group (NSSG) took the same dose of normal-sodium salt plus CM-DASH diet for 8 weeks. Blood tests, 24-hour urine tests, anthropometric measurements, and 10-year risk of ASCVD prediction were assessed. Results: compared with baseline, both LSSG and NSSG showed a significant reduction in 10-year risk of ASCVD, but we did not find any statistically significant differences in 10-year risk of ASCVD between LSSG and NSSG. Conclusions: our study shows that salt limits and DASH diets reduce the risk of cardiovascular disease whereas low-sodium salt containing 52 % sodium chloride did not significantly lower the risk of cardiovascular disease when compared to regular salt. Due to the limitations of the research, additional studies will be necessary to confirm our findings.

Resumen Introducción: la hipertensión y la diabetes son trastornos crónicos asociados a un mayor riesgo de enfermedad cardiovascular. Objetivos: evaluar el efecto de la sal baja en sodio (52 %) aplicada a la dieta DASH modificada en China (CM-DASH) sobre los riesgos de enfermedad cardiovascular aterosclerótica (ECA) en pacientes con hipertensión arterial y diabetes de tipo 2. Métodos: el grupo de sal baja en sodio (LSSG) tomó 5 g/día de sal baja en sodio al 52 % más dieta CM-DASH durante 8 semanas, mientras que el grupo de sal normal en sodio (NSSG) tomó la misma dosis de sal normal en sodio más dieta CM-DASH durante 8 semanas. Se evaluaron los análisis de sangre, los análisis de orina de 24 horas, las mediciones antropométricas y los riesgos de predicción de ECVA a 10 años. Resultados: en comparación con el valor basal, tanto el LSSG como el NSSG mostraron una reducción significativa de los riesgos a 10 años de ECVA, mientras que no se encontraron diferencias estadísticamente significativas en los riesgos a 10 años de ECVA entre el LSSG y el NSSG. Conclusiones: nuestro estudio muestra que los límites de sal y las dietas DASH reducen el riesgo de enfermedad cardiovascular mientras que la sal baja en sodio con un 52 % de cloruro sódico no redujo significativamente el riesgo de enfermedad cardiovascular en comparación con la sal normal. Debido a las limitaciones de la investigación, serán necesarios estudios adicionales para confirmar nuestros hallazgos

Abstract Background: The present study aimed to investigate the underlying role of interferon-regulatory factor 2 (IRF2)-inositol polyphosphate-4-phosphatase, type-II (INPP4B) axis in the regulation of autophagy in acute myeloid leukemia (AML) cells. Methods: Quantitative real time PCR (QRT-PCR) and western blot were performed to determine the expression levels of IRF2, INPP4B and autophagy-related markers in AML cell lines. Autophagy was assessed by elevated Beclin-1 expression, the conversion of light chain 3 (LC3)-I to LC3-II, downregulated p62 expression and green fluorescent protein (GFP)-LC3 puncta formation. The colony formation and apoptosis assays were performed to determine the effects of IRF2 and INPP4B on the growth of AML cells. Results: IRF2 and INPP4B were highly expressed in AML cell lines, and were positively correlated with autophagy-related proteins. Overexpression of IRF2 or INPP4B stimulated autophagy of AML cells, whereas inhibition of IRF2 or INPP4B resulted in the attenuation of autophagy. More importantly, IRF2 or INPP4B overexpression reversed autophagy inhibitor, 3-methyladenine (3-MA)-induced proliferation-inhibitory and pro-apoptotic effects, while IRF2 or INPP4B silencing overturned the proliferation-promoting and anti-apoptotic effects of autophagy activator rapamycin. Conclusion: IRF2-INPP4B signaling axis attenuated apoptosis through induction of autophagy in AML cells.

This study aimed to investigate the association of serum high-mobility group box-1 (HMGB1) and toll-like receptor 4 (TLR4) expressions with the risk of epilepsy as well as their correlations with disease severity and resistance to anti-epilepsy drugs. One hundred and five epilepsy patients and 100 healthy controls (HCs) were enrolled in this case-control study, and serum samples were collected from all participants to assess the HMGB1 and TLR4 expressions by enzyme-linked immunosorbent assay (ELISA). Both serum HMGB1 (P<0.001) and TLR4 (P<0.001) expressions were higher in epilepsy patients than in HCs, and they displayed good predictive values for risk of epilepsy. Moreover, HMGB1 was positively correlated with TLR4 level (r=0.735, P<0.001). HMGB1 and TLR4 levels were both elevated in patients with an average seizure duration >5 min compared to patients with a seizure duration ≤5 min (P=0.001 and P=0.014, respectively). Also, HMGB1 and TLR4 were increased in patients with seizure frequency >3 times per month compared to patients with seizure frequency ≤3 times per month (both P=0.001). In addition, HMGB1 and TLR4 expressions were higher in intractable cases compared to drug-responsive cases (P<0.001). In conclusion, both HMGB1 and TLR4 expressions were correlated with increased risk and severity of epilepsy and their level was higher in patients resistant to anti-epilepsy drugs.

A novel adsorbent based nanostructured bismuth oxyiodide (BiOI) microspheres combining the highly effective adsorption and green photocatalytic regeneration were fabricated by a facile and rapid low-temperature chemical bath method. The resultant products were characterized by X-ray diffraction (XRD), Scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), Nitrogen adsorption-desorption measurements, and UV-Vis diffuse reflectance spectroscopy (DRS). The BiOI microspheres displayed remarkable performance towards removal of Rhodamine B (RhB) and Cr (VI) from aqueous solution, showing a maximum adsorption capacity reached up to 40.78 mg g-1 and 38.01 mg g-1, respectively. The kinetics and equilibrium of adsorption process were found to follow the pseudo-second-order kinetic and Langmuir isotherm models. Notably, the BiOI microspheres have excellent photocatalytic regeneration capability due to their intrinsically prominent photoresponse in visible light region. By meaning of providing a new insight into the design of new generation adsorbent that could combine adsorption and solar-driven photocatalysis, the synthesized BiOI microspheres are very promising for the large-scale industrial application for water treatment.

Chitosanase production of Gongronella sp. JG cells immobilized in calcium alginate gel and polyurethane foam was compared with that of the free cells, there was a 60% increase in the enzyme yield (2429 U/L) compared to the highest yield obtained from free cells (1513 U/L). The optimal immobilization parameters (concentrations of sodium alginate, calcium chloride, bead inoculums, bead diameter, etc) for the enhanced production of chitosanase were determined as: sodium alginate 2% (w/v), 0.1 M calcium chloride, inoculum 10 mL beads to 100 mL production media and 2.7 mm bead diameter. Maximum chitosanase production was achieved with initial pH of 5.5 and temperature of 30 ºC. The alginate beads had well stability, retained 85% ability of enzyme production even after 7 cycles of repeated batch fermentation. These results showed the immobilization technique was a feasible and economical method for chitosansase production by Gongronella sp. JG.
