Objective To evaluate the effect of nursing intervention on the psychological status,complications and satisfaction in patients with cerebral hemorrhage.Methods A total of 184 patients with cerebral hemorrhage in the Third People's Hospital of Panzhihua City from January 2013 to June 2015 were randomly divided into observation group and control group with 92 cases in each group.The control group was treated with routine internal medicine nursing,and the observation group received nursing intervention on the basis of the control group.After 1 month,the Self-Rating Anxiety Scale (SAS) and Self-Rating Depression Scale (SDS) were used to evaluate the psychological status of the two groups before and after nursing.The incidence of complications and satisfaction were compared between the two groups.The quality of life of the two groups were assessed by the life activity ability rating (FIM) scale and the quality of life index (QLI).Results Compared with the control group,the SAS and SDS score of the observation group after the intervention were significantly improved (P＜0.05).The incidence of the observation group was significantly lower than that of the control group,and satisfaction was significantly higher than that of the control group (P＜0.05).The FIM and QLI of the observation group were significantly better than that of the control group (P＜0.05).Conclusion Nursing intervention can significantly improve the psychological status and quality of life,reduce the incidence of complications,and improve the satisfaction of patients with cerebral hemorrhage.It is worth popularizing widely.

Objective To study the similarities and differences in brain activation under N-back and DMTS paradigms of working memory. Methods Through searching of BrainMap function database by the combination keywords,a total of 122 articles with 122 experiments ( N-back: 67 experiments,937 sub-jects,900 foci;Delayed Matched to Sample: 55 experiments,806 subjects,872 foci). Maps were analyzed using the FDR PN (P<0. 0001) method based coordinates of the Montreal Neurological Institute ( MNI) space. Results In the combine of the N-back and DMTS paradigms,these regions were activated including the bilateral inferior parietal lobe (Left: -36,-52,44; Right: 38,-52,48) and insula(Left:-34,22,0;Right:34,24,2),the superior frontal gyrus (2,16,50) and inferior frontal gyrus (-44,8,30) of the left brain,and the middle frontal ( 46,36,24) and sub-gyral ( 30,4,56) of the right brain. The N-back paradigm was similar to the above results,whereas the DMTS paradigm only activated the precentral gyrus (-50,8, 34) of the left brain and the right insula ( 34,24,4) . Conclusion The neural circuit of working memory is the frontal-parietal networks. N-back paradigm with the brain activation consists to the neural circuit of work-ing memory. However,DMTS paradigm activates less brain regions and is inconsistent to the neurons of work-ing memory.

There is an imbalance between the supply and demand of functional red blood cells (RBCs) in clinical appli-cations. This imbalance can be addressed by regenerating RBCs using several in vitro methods. Induced pluripotent stem cells (iPSCs) can handle the low supply of cord blood and the ethical issues in embryonic stem cell research, and provide a promising strategy to eliminate immune rejection. However, no complete single-cell level differentiation pathway exists for the iPSC-derived erythroid differentiation system. In this study, we used iPSC line BC1 to establish a RBC regeneration system. The 10X Genomics single-cell transcriptome platform was used to map the cell lineage and differentiation trajectory on day 14 of the regeneration system. We observed that iPSC differentiation was not synchronized during embryoid body (EB) culture. The cells (on day 14) mainly consisted of mesodermal and various blood cells, similar to the yolk sac hematopoiesis. We identified six cell classifications and characterized the regulatory transcription factor (TF) networks and cell–cell contacts underlying the system. iPSCs undergo two transformations during the differentiation trajectory, accompanied by the dynamic expression of cell adhesion molecules and estrogen-responsive genes. We iden-tified erythroid cells at different stages, such as burst-forming unit erythroid (BFU-E) and orthochromatic erythroblast (ortho-E) cells, and found that the regulation of TFs (e.g., TFDP1 and FOXO3) is erythroid-stage specific. Immune erythroid cells were identified in our system. This study provides systematic theoretical guidance for optimizing the iPSC-derived erythroid differentiation system, and this system is a useful model for simulating in vivo hematopoietic develo-pment and differentiation.

Age-dependent loss of skeletal muscle mass and function is a feature of sarcopenia, and increases the risk of many aging-related metabolic diseases. Here, we report phenotypic and single-nucleus transcriptomic analyses of non-human primate skeletal muscle aging. A higher transcriptional fluctuation was observed in myonuclei relative to other interstitial cell types, indicating a higher susceptibility of skeletal muscle fiber to aging. We found a downregulation of FOXO3 in aged primate skeletal muscle, and identified FOXO3 as a hub transcription factor maintaining skeletal muscle homeostasis. Through the establishment of a complementary experimental pipeline based on a human pluripotent stem cell-derived myotube model, we revealed that silence of FOXO3 accelerates human myotube senescence, whereas genetic activation of endogenous FOXO3 alleviates human myotube aging. Altogether, based on a combination of monkey skeletal muscle and human myotube aging research models, we unraveled the pivotal role of the FOXO3 in safeguarding primate skeletal muscle from aging, providing a comprehensive resource for the development of clinical diagnosis and targeted therapeutic interventions against human skeletal muscle aging and the onset of sarcopenia along with aging-related disorders.
