Understanding of Five Grains for YANG:a way to straighten Asians’dietary structure

According to the general opinion,grains should occupy the largest amount of human food each day,but this grain-based eating habit does not allow human life to be extended.Grains are high in carbohydrates and five commonly recognized plant hormones,namely auxin,gibberellin,cytokinin,abscisic acid,and ethylene.Through in-depth analysis of ancient books,it was found that five grains for support:support is a restriction,and it means the essence,which means that grains should be eaten less,and it is the essence of the least daily intake.To correctly understand the Chinese dietary concept of"five grains for support"is the basis for improving Asian dietary health and promoting Asian human health.

Role of autophagy in acute myeloid leukemia therapy

Despite its dual role in determining cell fate in a wide array of solid cancer cell lines, autophagy has been robustly shown to suppress or kill acute myeloid leukemia cells via degradation of the oncogenic fusion protein that drives leukemogenesis. However, autophagy also induces the demise of acute leukemia cells that do not express the known fusion protein, though the molecular mechanism remains elusive. Nevertheless, since it can induce cooperation with apoptosis and differentiation in response to autophagic signals, autophagy can be manipulated for a better therapy on acute myeloid leukemia.

Exact quantum dynamics study of the H(^(2)S)+SiH^(+)(X^(1)Σ^(+))reaction on a new potential energy surface of SiH_(2)^(+)(X^(2)A_(1))

Based on a new global potential energy surface of SiH_(2)^(+)(X^(2)A_(1)),the exact quantum dynamical calculation for the H(^(2)S)+SiH^(+)(X^(1)Σ^(+))→H_(2)+Si^(+)reaction has been carried out by using the Chebyshev wave packet method.The initial state specified(νi=0,ji=0)probabilities,integral cross sections(ICS)and thermal rate constants of the title reaction are calculated.All partial wave contributions up to J=90 are calculated in exact quantum calculation including the full Coriolis coupling(CC)effect.The dynamical behaviors of probabilities,ICSs and rate constants are found to be in accord with an exothermic reaction without potential barrier.By comparing the probabilities of CC with the corresponding centrifugal sudden(CS)approximation ones,it can be concluded that neglecting CC effect will decrease the collision time,increase the amplitude of oscillation and lead to overestimation or underestimation of the reaction probability.For ICSs and rate constants,it is found that the deviation of CC and CS ICSs is small in the most of collision energy range except for the range of 0 eV-0.05 eV,while the deviation of both rate constants is considerable in the temperature range of 16 K-1000 K.

Delivery room resuscitation and short-term outcomes of extremely preterm and extremely low birth weight infants: a multicenter survey in North China

Background:Delivery room resuscitation assists preterm infants,especially extremely preterm infants(EPI)and extremely low birth weight infants(ELBWI),in breathing support,while it potentially exerts a negative impact on the lungs and outcomes of preterm infants.This study aimed to assess delivery room resuscitation and discharge outcomes of EPI and ELBWI in China.Methods:The clinical data of EPI(gestational age[GA]<28 weeks)and ELBWI(birth weight[BW]<1000 g),admitted within 72 h of birth in 33 neonatal intensive care units from five provinces and cities in North China between 2017 and 2018,were analyzed.The primary outcomes were delivery room resuscitation and risk factors for delivery room intubation(DRI).The secondary outcomes were survival rates,incidence of bronchopulmonary dysplasia(BPD),and risk factors for BPD.Results:A cohort of 952 preterm infants were enrolled.The incidence of DRI,chest compressions,and administration of epinephrine was 55.9%(532/952),12.5%(119/952),and 7.0%(67/952),respectively.Multivariate analysis revealed that the risk factors for DRI were GA<28 weeks(odds ratio[OR],3.147;95%confidence interval[CI],2.082–4.755),BW<1000 g(OR,2.240;95%CI,1.606–3.125),and antepartum infection(OR,1.429;95%CI,1.044–1.956).The survival rate was 65.9%(627/952)and was dependent on GA.The rate of BPD was 29.3%(181/627).Multivariate analysis showed that the risk factors for BPD were male(OR,1.603;95% CI,1.061–2.424),DRI(OR,2.094;95% CI,1.328–3.303),respiratory distress syndrome exposed to≥2 doses of pulmonary surfactants(PS;OR,2.700;95%CI,1.679–4.343),and mechanical ventilation≥7 days(OR,4.358;95% CI,2.777–6.837).However,a larger BW(OR,0.998;95% CI,0.996–0.999),antenatal steroid(OR,0.577;95%CI,0.379–0.880),and PS use in the delivery room(OR,0.273;95%CI,0.160–0.467)were preventive factors for BPD(all P<0.05).Conclusion:Improving delivery room resuscitation and management of respiratory complications are imperative during early management of the health of EPI and ELBWI.
