9% in REM sleep and 8.1% in wakefulness). The electroencephalography spectrum during sleep paralysis was intermediate between wakefulness and REM sleep in the alpha, theta, and delta frequencies, whereas the beta frequencies were not different between sleep paralysis and normal REM sleep. The power spectrum during false awakening followed the same profile as in sleep paralysis.

The predominant theta electroencephalography rhythm during sleep paralysis and false awakenings (with rare and lower alpha rhythm) suggests that the brain during sleep paralysis is not in an awake but in a dreaming state.

The abnormal expression of EZH2 has been described in many cancer types. With in-depth study, it was found that EZH2 is involved in the occurrence and development in many kinds of malignant hematologic disease which may play a dual role of oncogenes and tumor suppressor genes. Clozapine N-oxide solubility dmso In recent years, the emergence of EZH2 inhibitors provide a new option for the future treatment of hematological malignancies. In this review, the expression and clinical significance of EZH2 in various of hematological tumors were summarized briefly.Tyrosine kinase inhibitor (TKI) has significantly improved the treatment of chronic myeloid leukemia (CML), however the resistance often resulted in treatment failure. Currently, it is known that the survival of CML cells can be affected by regulating autophagy, oxidative stress and mitochondrial metabolism, among which autophagy is an evolution-conserved catabolism process, and closely related to the pathogenesis of CML, thus playing a dual role in regulating the biological characteristics of cells. On the one hand, autophagy can promote the apoptosis of CML cells, and also can induce the drug resistance of CML cells on the other hand. In this review, the effect of autophagy on CML cells was summarzed briefly, so as to provide a useful idea to explore the combination of TKI with the autophagy inhibitor or inducer to overcome the resistance of CML to TKI.Acute myeloid leukemia (AML) is a malignant tumor with abnormal myelocyte differentiation. With the development of immunological technology, great importance has been attached to the immunotherapy of AML patients, which may become an effective treatment strategy for AML, and providing a new means for the prognosis and survival. In this review, the advanced research of immunotherapy for AML, such as antibody-dependent drugs, chimeric antigen receptor T cell therapy, and checkpoint inhibitors, the bastest reaserch advanves of clinical experiment for immunotherapy was summarized briefly.Exosomes are microvesicles that can be secreting in many kinds of cells, under the condition of normal and pathology. Exosomes contain abundant proteins, miRNAs and RNA fragments, which play an important role in communicating between cells, especially non-contact cells. The interaction between blood tumor cells and immune microenvironment is inseparable from the involvement of exosomes. Exosomes are involved in the interaction among tumor cells, NK cells, T cells, stromal cells and endothelial cells, such as promoting the proliferation of blood tumor cells, helping blood tumor cells to achieve immune evasion, promoting angiogenesis and migration of tumor cells. Therefore, exosomes are closely related to the diagnosis, treatment and prognosis of hematological tumors. link2 In this review, the basic characteristics of exosomes, the important role of exosomes in the immune microenvironment of hematological tumors, and the research progress of exosomes in clinical applications was sammrized briefly.
To observe the clinical and laboratory characteristics of adult Langerhans cell histiocytosis(LCH) patients and to analyze the influencing factors of its prognosis.

The clinical and laboratory charac-teristics of 38 adult LCH patients treated in our hospital from January 2010 to August 2019 were retrospective analyzed, and the clinical prognosis of the patients was analyzed.

The median age of 38 patients was 41 (21-65) years old, and the ratio of male and female was about 2∶1. Among 38 patients, 44.7% (17/38) were involved in multiple systems, and 31.6% (12/38) were involved in high-risk organs (including liver, lung, hematopoietic system or spleen). The bone involvement was the most common (21/38, 55.3%), and the most common clinical symptom was pain (19/38, 50.0%). The result of laboratory showed that anemia (4/38，10.5%), thrombocytopenia (1/38，2.6%), neutropenia (2/38，5.3%), lymphopenia (6/38，15.8%), monocytosis (11/38，28.9%), C-reactive protein increasing (6/21，28.6%), erythrocyte sedimentation rateincreasing of monocyte cells and the increasing of ferritin protein were the independent risk factors of adult LCH patients.
To investigate the changes of GATA-1 protein expression during erythroid differentiation of K562 cells under hypoxia and how GATA-1 can regulate erythroid differentiation by up-regulating the expression of miR-451a and inhibiting the expression of 14-3-3ζ.

K562 cells were divided into 2 groups the normoxia group and the hypoxia group, after the induction of hemin for 96 h, the positive cells rate of the benzidine staining, the mRNA expression of γ-globin and the expression of CD235a were detected, and the success of the model was verified. The changes of GATA-1 and miR-451a expression in the above-mentioned 2 groups, the changes of miR-451a expression after over-expressed GATA-1 were detected by Western blot and qRT-PCR. The cells in normoxic group and hypoxia group were divided into negative control group (NC group) and miR-451a over-expression group respectively, and the degree of erythroid differentiation in the four groups was judged according to the corresponding erythroid differentiation indexes, an
Hypoxia can significantly increase the expression of GATA-1 protein, and the increase of GATA-1 expression can up-regulate the expression of miR-451a, thereby inhibiting the expression of 14-3-3ζ protein, which hinders the cell proliferation in erythroid differentiation model of K562 cells and plays an important role in promoting erythroid differentiation.

To study two novel CD36 gene mutations at the CD36 splicing sites found in Guangxi population, as well as the molecular basis and population incidence of them.

DNA sequencing and cDNA clonal sequencing were used to detect CD36 exon sequence and the protein coding region sequence of CD36 mRNA for 2 CD36 deficient individuals (HHC and WGM) found in Guangxi population. Eukaryotic expression cell lines were established for the discovery of CD36 mRNA abnormal transcripts and Western blot assay was used to verify the effect of abnormal CD36 mRNA transcripts on CD36 expression. A DNA PCR-SSP genotyping method was established for the two CD36 novel mutations, and the population distribution was investigated among 110 CD36 deficient individuals in Guangxi region and 296 random individuals in Guangxi population.

Novel mutation of c.430 -1G>C was found at the CD36 splicing site in HHC and WGM individuals, and novel mutation of c.1006 +2T>G at the CD36 splicing site was also found in the WGM individual. CD36 ncy and the distribution characteristics in Guangxi population as well. It provides an experimental and theoretical basis for studying the molecular mechanism and characteristics of CD36 deficiency in Chinese population.

To investigate the effect of IL-27 on Th17 cells in patients with henoch-schönlein purpura（HSP） in order to further elucidate the pathogenesis.

Fifty patients with HSP treated in our hospital from April 2019 to July 2019 were selected as HSP group, and 30 volunteers underwent physical examination at the same time were selected as control group. The proportion of Th17 cells in peripheral blood of HSP group and healthy control group was determined by flow cytometry (FCM). A total of 27 HSP patients were selected, and candidate peripheral blood mononuclear lymphocytes (PBMC) were co-cultured with exogenous rhIL-27, and the ratio of Th17 cells was detected by flow cytometry.

The proportion of Th17 cells in the peripheral blood of HSP patients with acute phase was (1.57±0.54)%, which was significantly higher than that of the control group (0.86±0.40)% (t=-6.298, P<0.001), and the proportion of Th17 cells was decreased significantly after rhIL-27 co-culture (1.39%±0.52% vs 0.98%±0.44%)(P<0.05).

IL-27 can reduce the level of Th17 cells in patients with HSP, which may be involved in the pathogenic process of HSP and play a protective role in the development of the disease.
