Differential gene expression profiles in Balb/cJ mouse model of acute hepatic failure infected with MHV-3 virus intervened by anti-hepatic failure compound (AHFC) and the changes of cytokines regulated by genes were investigated. The Balb/cj mice were divided into AHFC-intervened group and control group randomly. Acute hepatic failure model of Balb/cJ mice infected with MHV-3 virus was established. The survival rate in the two groups was observed. It was found that the survival rate in the AHFC-intervened group and control group was 90% and 50% respectively 48 h after intraperitoneal injection of MHV-3 (P<0.05). Before and after the experiment, the cytokines in peripheral blood of the survival mice were determined, and RNA was extracted from survival mouse liver tissue for the analysis of the differential gene expression by a 36 kb mouse oligonucleotide DNA array. In all the genes of microarray there were 332 genes expressed differently in the two groups, in which 234 genes were up-regulated and 78 genes down-regulated. Through clustering analysis, the differential expression of immune related genes, including TNF receptor superfamily, Kctd9, Bcl-2, Fgl2, IL-8, IL-6, IFN-gamma, TNF-alpha etc. might be related with the curative effectiveness of AHFC. It was suggested that AHFC can balance the immune state of mouse model of acute hepatic failure infected with MHV-3 virus mainly through regulating the expression of immune related genes, decrease the immune damage and inhibit liver cell apoptosis of mouse acute hepatic failure model obviously so as to increase the survival rate of mouse models of acute hepatic failure.

Objective To investigate the changes and prognostic significance of bone marrow(BM) oil drop and megakaryocyte counts after chemotherapy in acute myeloid leukemia (AML) patients (non-M3).Methods Ninty-nine adult patients with denovo AML (non-M3) were retrospectively analyzed to evaluate the change of BM oil drop and megakaryocyte counts and their influences on overall survival(OS) and disease free survival (DFS) during all stages of standardized therapy.Results The median DFS and OS were 21 (2-88);months and 70 (4-89) months,respectively; and 3-year predicted DFS and OS were 47.3 % and 55.8 %,respectively.After AML patients (non-M3) achieving complete remission (CR) by induction therapy,BM oil drop tended to increase along with postremission chemotherapy cycle accumulation, while megakaryocyte counts tended to decrease.The univariate analysis indicated that megakaryocyte counts decreased after the second course of postremission therapy. BM oil drop increased after the first to the third course of postremission therapy.Grade of myelofibrosis in BM biopsy,serum lactate dehydrogenase (LDH) level at diagnosis,flow cytometric immunophenotyping, the percentage of BM blast cells at diagnosis and the percentage of residual leukemic cells (RLC) during aplasia (7-10 days after the end of induction therapy) had prognostic significance.Multivariable COX analysis indicated the percentage of BM blast cells at diagnosis and change of BM oil drop after the third postremission therapy were independent prognostic factors for DFS (P =0.010,0.018 respectively),and RLCs during aplasia and change rate of the megakaryocyte counts after the second postremission therapy were independent prognostic factors for OS (P =0.009, 0.038respectively).Conclusion After AML patients (non-M3) achieving CR by induction therapy,BM oil drop tends to increase along with postremission chemotherapy cycles accumulation,while the megakaryocyte counts tend to decrease.Dynamic observations of bone marrow oil drop and megakaryocyte counts are helpful for assessing the prognosis of acute myeloid leukemia (non-M3).

This article presents a transcutaneous electric stimulator that is based on chaotic signal. Firstly, we in the study used the MATLAB platform in the PC to generate chaotic signal through the chaos equation, and then we transferred the signal out by data acquisition equipment of USB-6251 manufactured by NI Company. In order to obtain high-power signal for transcutaneous electric stimulator, we used the chip of LM3886 to amplify the signal. Finally, we used the power-amplified chaotic signal to stimulate the internal nerve of human through the electrodes fixed on the skin. We obtained different stimulation effects of transcutaneous electric stimulator by changing the parameters of chaotic model. The preliminary test showed that the randomness of chaotic signals improved the applicability of electrical stimulation and the rules of chaos ensured that the stimulation was comfort. The method reported in this paper provides a new way for the design of transcutaneous electric stimulator.

Objective:To investigate the clinical features, the key point of diagnosis and treatment methods of X-linked hyper-IgM syndrome (XHIGM).Methods:The clinical characteristics and laboratory data of a patient aged 23 years who was diagnosed as XHIGM complicated with T-cell large granular lymphocytic leukemia (TLGLL) in Institute of Hematology & Blood Diseases Hospital in March 2020 were analyzed retrospectively, and the literatures were reviewed.Results:This male patient presented with recurrent infection when he was 17 years old, and was found neutropenia, anemia accompanied by obvious splenomegaly, lower level of IgG and IgA after the visit. The level of IgM was lower than the normal level and the typical XHIGM was manifested with the normal or increased level of IgM, however CD40L homozygous mutation (chromosome: chrX; location: 135730438; variation of amino acid: NM_000074:exon1:c.31C>T:p.R11X; nonsense mutation) was confirmed by next generation sequencing. CD40L heterozygous mutation was detected in his mother, but it was not in his father. The patient was diagnosed as XHIGM. Anemia and neutropenia were alleviated after splenectomy in the patient, who was diagnosed as T-cell large granular lymphocyte elevation and clonal proliferation by flow cytometry, TCR gene rearrangement positive and bone marrow histopathological immunohistochemistry results because of the increasing leukocyte. The patient was eventually diagnosed as XHIGM complicated with T-LGLL.Conclusions:A small number of patients with XHIGM may develop symptoms in adulthood and may present with atypical clinical features of significant reduction in IgG, IgA, and IgM. The confirmed diagnosis of XHIGM is established by identification of CD40L gene mutation. XHIGM gene screening is required in male patients with recurrent infection, IgG level lower than normal and neutropenia. A few XHIGM patients are complicated with T-LGLL.
