35 min. The optimal OD value was 0.8437. RBC, WBC, and Hb in the water fraction (5, 10 g/kg) and -butanol fraction (10 g/kg) intervention groups increased significantly compared with the model group (  < 0.05). Polysaccharide and caffeic acid contents of water fraction were 252.565 and 0.346 μg/mg, respectively; ferulic acid was not detected. Caffeic acid and ferulic acid contents of -butanol fraction were 1.187 and 0.806 μg/mg, respectively, polysaccharide was not detected. The optimum preparation technology of WASD was obtained, and the water, -butanol fractions were blood-supplementing fractions. This study provides a theoretical foundation for further application of WAS in the pharmaceutical industry.The optimum preparation technology of WASD was obtained, and the water, n-butanol fractions were blood-supplementing fractions.

To analyse the intra-operative neurophysiological monitoring (IONM) data in patients with dystrophic neurofibromatosis type 1 (NF1) associated scoliosis, and to investigate the possible risk factors for failed IONM monitoring. Patients undergoing posterior spinal fusion from September 2015 to December 2019 were retrospectively reviewed. The latency (P37, N50) and amplitude of somatosensory evoked potentials (SEP) in bilateral lower extremities, latency and amplitude of motor evoked potentials (MEP) in bilateral lower extremities and unilateral upper extremity were recorded. The neurological status, curve pattern, Cobb angle of main curve, vertebral rotatory subluxation and dystrophic features at pre-operation were assessed for each patient. The failed IONM monitoring was defined as no reliable SEP or MEP waveforms of all monitored muscles. A total of 92 patients (53 M, 39 F) with an average age of 14.1 ± 2.7 years were included. Failed IONM monitoring was identified in 17 patients with overall success rates being 87.0 and 94.6% for SEP and MEP. The average P37 latency, N50 latency, SEP amplitude and MEP latency showed no significant difference between concave and convex sides (  > 0.05 for all). The MEP amplitudes of lower extremities were lower on concave side than convex side (334.5 ± 291.9 µV VS 417.5 ± 380.5 µV,  = 0.030). Higher risk of failed IONM monitoring was found in patients with neurological deficit (  = 0.014) and more dystrophic features (  = 0.002) at pre-operation. The overall success rates were 87.0% for SEP and 94.6% for MEP in patients with NF1-associated scoliosis. Neurological deficit and more dystrophic features at pre-operation indicated higher risk of failed IONM monitoring.The overall success rates were 87.0% for SEP and 94.6% for MEP in patients with NF1-associated scoliosis.

Urban communities may be increasingly exposed to stressors such as crime and concentrated poverty whereas rural communities may be devoid of important community resources. As a result, the experience of stress in poverty may differ by place of residence. The goal of this study was to examine differences in HCC among urban and rural-dwelling mother-child dyads in socioeconomically disadvantaged communities surrounding La Romana, DR. Forty-five mother/child dyads were enrolled in La Romana and 45 at several bateyes surrounding La Romana. Mothers were ≥18 years and children were between 7 and 14 years. Mothers self-reported perceived stress and demographic factors. H cortisol levels than Dominican born mothers. Hair cortisol levels between mothers and their children were positively associated. This study addresses the impact of urban and rural environments on the stress response among socioeconomically disadvantaged persons living in an upper middle income country who bear an excessive burden of psychosocial stress.There are approximately 38 million people globally living with Human immunodeficiency virus 1 (HIV-1) and given the tremendous success of combination antiretroviral therapy (cART) this has dramatically reduced mortality and morbidity with prevention benefits. However, HIV-1 persists during cART within the human body and re-appears upon cART interruption. This HIV-1 reservoir remains a barrier to cure with cellular sites of viral persistence not fully understood. In this study we provide evidence corroborating a recently published article in STM demonstrating the role of platelets as a novel cellular disseminator of HIV-1 particles in the setting of viral suppression. Using classical transmission electron microscopy with and without immunogold labeling, we visualize HIV-1 in both platelets and monocytes in cART suppressed HIV donors. Our study suggests that due to the close proximity of platelets and monocytes an alternative life cycle of HIV-1 cycling within monocytes and platelets without the need of active replication under cART occurs. Our findings are supported by the lack of detectable HIV-1 particles in platelets derived from HIV uninfected donors or the 'Berlin' patient suggesting that platelets may serve as an underappreciated hidden bearer for HIV-1 and should be considered in HIV remission studies and trials.Hb E [β26(B8)Glu→Lys, GAG>AAG, HBB c.79G>A] is an inherited thalassemic β-globin variant that favors the Hb E-β-thalassemia (β-thal) syndrome when interacting with the β-thal gene. However, hemoglobin (Hb) variants carrying Hb E in combination with another variant on the same β gene are rare. We recently studied a 29-year-old pregnant woman, initially diagnosed as a β-thal carrier. Hemoglobin and DNA analysis were performed by high performance liquid chromatography (HPLC) and DNA sequencing. Hematological data revealed no anemia or altered red blood cell (RBC) parameters. Hemoglobin HPLC showed Hb A and Hb A2 but no Hb E or abnormal Hb peaks, with a markedly elevated Hb A2 level (6.4%) reaching the accepted range (4.0-10.0%) for β-thal trait. DNA analysis identified a GAG>AAG transition at codon 26 of the β-globin gene that is responsible for Hb E, and an AAG>AAC mutation at codon 65 in cis on the β-globin chain resulting in a lysine to asparagine substitution. These two mutations led to the formation of a novel variant, namely Hb E-Myanmar, β26(B8)Glu→Lys and β65(E9)Lys→Asn, HBB c.
