Objective To report a case of psoriasis vulgaris associated with acute myelogenous leukemia(AML)(type M4EO).Methods Clinical data from the patient were collected.Histopathologic examination,and examination of bone marrow and peripheral blood smear were performed.The immunologic types of bone marrow cells were analyzed with FACS.Chromosome and G-banding analyses were carried out with cultured bone marrow cells.Results A33-year-old woman had a history of chronic plaque psoriasis for20years.Her cousin had the same disease history.The patient was treated with various therapeutic regi-mens,most of which were traditional Chinese medicines.Recently the patient suffered from myalgia and chest bone pain,periodic bleeding on gums,fever and so on.The abnormal infantile monocytes and promye-locytes were found with bone marrow smear,and crassitude basophilic granules were noticed in eosinophils.The diagnosis of acute myelogenous leukemia type M4EO was made.The diagnosis was confirmed with the immunologic analysis of born marrow cells with FACS.Chromosome and G-banding analyses revealed her karyotype of46,XX,inv(16)/47,XX,inv(16),+8(2/22).The plaque lesions of psoriasis were regressed after allogeneic bone marrow transplantation and the symptoms of AML were resolved.Conclusion It is the first case report of psoriasis vulgaris associated with acute myelogenous leukemia M4EO which responded to allogeneic bone marrow transplantation.

Objective To study the relationship between apoptosis regulation and epidermal proliferation in psoriasis. Methods The expression of apoptosis molecule PDCD5 (programmed cell death 5) on psoriatic lesions was observed by direct immunofluorescence. The positive rates and the average of fluorescence intensity of PDCD5 were analyzed quantitatively with FACS and computer CELL Quest software. The expression of PDCD5 mRNA in psoriatic lesions was detected by RT-PCR. Results The expression of PDCD5 protein was obviously lower in psoriatic epidermal cells than that of the normal skin. The positive rate and the average fluorescence intensity of PDCD5 in psoriatic epidermal cells were notably lower than those of the normal skin (P

Objective To study the role of phosphorylation at Serine 129 in regulating the neurotoxicity of ?-synuclein. Methods Wild type and phosphomimic mutant ?-synuclein genes were over-expressed in mouse dopaminergic cells MN9D using retrovirus. The cell viability was examined using CCK-8 assay and cell morphology was observed by immunofluorescence microscopy. Results The result of real time PCR showed that WT/?-SYN and S129D/?-SYN genes were overexpressed in MN9D as compared to uninfected MN9D and vector control group(P

Objective:
To analyze the genetic characterization of glycoprotein M(gM.),glycoprotein L(gL) of varicella zoster virus.
Methods:
According to the program of "Ministry of Science and Technology of China" , Based on the 12 suspected VZV patients monitored in Beijing (1 case), Shanghai (5 cases), Jilin (2 cases), Qinghai (1 case), Guangdong (2 case) and Sichuan (case) in 2007-2015. A total of 12 Vesicle fluid and throat swab samples were collected. Positive samples were identified by Agarose gel electrophoresis and two glycoprotein genes were amplified by polymerase chain reaction (PCR). Nucleotide sequences were determined and analyzed by PCR amplification of VZV positive specimens V-OKA-BK of the domestic varicella attenuated live vaccine and the Varilrix-1 of the imported attenuated live vaccine. Nucleotide sequences of VZV positive specimens, vaccine strains (V-OKA-BK, varilrix-1) and GenBank foreign wild strains (41 strains), parent strains (P-oka), vaccine strains (V-oka, Varilrix, Varivax) were compared using BioEdit and MEGA 5.0.
Results:
12 specimens were VZV positive. Compared with the vaccine strains and the parent strains, the GM gene of 1 positive specimen had radical mutation at 86686 sites, which resulted in amino acid mutation, 5 positive specimens had base mutation at 87844 sites, and 30 strains of foreign wild strains had the same variation at 87 844 sites. 1 positive specimens of gL gene in 101245 sites had base mutation, and led to amino acid mutation, 6 positive specimens at 101624, 101625, 101626 sites had base of loss and the foreign wild strains in these 3 sites had the same variation. Compared with the vaccine strains, the nucleotide and amino acid homology of gM of 12 VZV positive specimens were 99.2%-100% and 98.2%-100%, respectively, and gL of those were 99.3%-100% and 98.6%-100%, respectively. Compared with 41 strains of foreign wild strains, homology of gM's nucleotides and amino acid were 99.3%-100% and 98.5%-100%, respectively; 99.1%-100% and 98.6%-100% for gL. The results of phylogenetic analysis showed that 7 VZV positive samples were on the same branch with 4 vaccine strains and p-oka strain. Based on gL, 12 VZV positive samples were on the same branch as the vaccine strains and p-oka strain.
Conclusion
This study demonstrates that the genes of gM, gL are highly conserved and remain stable immunogen, which may be involved in the attenuation of VZV and need to be further researched.

Ulcerative colitis (UC) is a chronic non-specific inflammatory disease characterized by the damage of the epithelial barrier of the colon and the destruction of immune homeostasis. It has a long course, no recovery and high recurrence rate, and is recognized as a difficult digestive disease. MicroRNA (miRNA) has been confirmed to be specifically or differentially expressed in both UC patients and UC animal models, so miRNA can be used as markers for UC diagnosis or reference for treatment evaluation. TCM therapy has a definite therapeutic effect, a wide range of effects, and minimal side effects in the treatment of UC, so this article takes miRNA as the starting point and systematically elaborates on the mechanism of TCM regulating UC related signaling pathways by regulating the expression of miRNA. The results show that chlorogenic acid, Anchang decoction, and Fuyang huoxue jiedu formula can regulate the expressions of miR-155, miR-146a and miR-31-5p, etc., thereby inhibiting signal transducer and activator of transcription (STAT) signal pathway transduction to improve UC. Limonin, ginsenoside Rh2, artesunate, etc. can inhibit nuclear factor-κB (NF-κB) signaling pathway conduction to improve UC by regulating the expressions of miR-214, miR- 155 and miR-19a, etc. Nitidine chloride, berberine, resveratrol, etc. can regulate the expressions of miR-31, miR-146a, miR- 146b, etc., thereby inhibiting the Toll-like receptor 4 (TLR4) signaling pathway to improve UC. Mango polyphenolics, Compound qinbai granules, and Astragalus membranaceus polysaccharides can regulate the expressions of miR-126 and miR-193a-3p, thereby inhibiting the phosphoinositide 3-kinase/protein kinase B/mammalian target of rapamycin (PI3K/AKT/mTOR) signaling pathway to improve UC.
