Chronic urticaria is a very common allergic disease in the outpatient.It has complicated pathogenesis and there is no conclusion up to now.The activation of the mast cells and the release of the histamine are the key point of the chronic urticaria onset.In recent years,the studies have demonstrated that the autoimmunity and the chronic infection are the main cause of the disease.There are other factors including dysfunction of the coagulation,deficiency of the vitamin D,pseudoallergen,psychic factor and genetic mechanism.This article will make a review of the pathogenesis of the chronic urticaria from the aspects mentioned above.

Objective:To analyse the whole DNA methylation status , expression of DNMT1 and DNA methylation status of DNMT1 promoter from patients with systemic lupus erythematosus ( SLE) .To assess the negative feedback effection of DNA methylation on the expression of DNMT1 in the patients with SLE.Methods:The whole DNA methylation status in T cells from 34 SLE patients and 23 healthy controls was assessed by the specific monoclonal antibodies to 5-methylcytosine (5-mc) and the DNA methylation status of DNMT1 promoter was assessed by the Bisulfite Conversion Kit and sequencing.Real time RT-PCR was applied to analyse DNMT 1 mRNA levels in T cells from the patients and controls.Results: SLE patients had siginificantly whole DNA hypomethylation than controls(P<0.05),and the whole DNA methylation was negative correlated with the SLE-DAI.There was no difference in levels of DNA methylation of DNMT1 promoter between patients and controls ,also no correlation between the levels of DNA methylation of DNMT 1 promoter and DNMT1 mRNA.Conclusion:There was no negative feedback effection of DNA methylation on the expression of DNMT 1 in the patients with SLE.The mechanism of lower expression of DNMT 1 in patients with SLE should be studied further.

OBJECTIVE: To study whether the therapeutic action of compound glycyrrhizin(SNMC) on allergic disorders can be achieved through inhibition on the expression of chemotactic factors in peripheral blood mononuclear cells(PBMC).METHODS: PBMC of 15 healthy subjects were obtained and divided into 4 drug-treated groups: SNMC group,dexamethasone group,mizolastine group,and loratadine group;meanwhile,a positive control group(proinflammatory stimulant was added) and a negative control group(no proinflammatory stimulant was added) were used as control.Fluorescent quantitation polymerase chain reaction was employed to determine the mRNA expression of the chemotatic factors including RANTES,MCP-1,MIP-1? and ELISA was employed to detect their concentrations in supernatant.RESULTS: In the positive control group,both the mRNA expressions and the concentrations of the 3 chemotatic factors increased significantly,and which were significantly lower in the drug-treatment groups than in the positive control group.There were significant differences between the positive control group and dexamethasone-treated group or SNMC-treated group in the expression of MIP-1? mRNA(P

Objective To investigate the effect of continuous nursing on the psychological status and quality of life in patients with low rectal cancer after Miles operation.Methods A total of 84 patients with low rectal carcinoma underwent Miles operation were selected from August 2014 to August 2016 in Henan Rongjun Hospital.The patients were divided into observation group (n =38) and control group (n =46) according to nursing measures.The patients in the control group were given routine nursing measures,while the patients in the observation group were given continuous nursing measures on the basis of routine nursing care.The psychological status and quality of life of the patients were compared between the two groups before and after intervention.Results There was no significant difference in swlf-rating anxiety scale (SAS) and self-rating depression scale(SDS) scores between the two groups before intervention (P ＞ 0.05).After six months intervention,the SAS and SDS scores in the two groups were significantly lower than those before intervention,and the scores of SAS and SDS in the observation group were significantly lower than those in the control group (P ＜0.05).There was no significant difference in the quality of life between the two groups before intervention (P ＞ 0.05).After six months intervention,the quality of life of patients in the two groups were significantly higher than those before intervention,and the quality of life of patients in the observation group were significantly higher than those in the control group (P ＜ 0.05).Conclusion Continuous nursing can significantly improve the negative emotions of anxiety and depression,and improve the quality of life in patients with low rectal cancer after Miles operation.

Objective To investigate the mRNA expression of CC Chemokines, including RANTES (regulated upon activation, normal T cell expressed and secreted), monocyte chemoattracctant protein-1 (MCP-1), monocyte chemoattracctant protein-3 (MCP-3) and macrophage inhibitory protein 1? (MIP-1?), in peripheral blood mononuclear cells (PBMCs) of patients with chronic urticaria, their mutual correlation, and the relationship between the expression level of CC chemokines and the serum level of IgE and eosinophil cationic protein (ECP) in the patients. Methods Reverse transcription-polymerase reaction (RT-PCR) was applied to semiquantitatively analyze the mRNA expression of RANTES, MCP-1, MCP-3 and MIP-1? in PBMCs from 31 patients with chronic urticaria and 22 healthy subjects. Results The mRNA expression of RANTES, MCP-1, MCP-3 and MIP-1?was significantly higher in the patients than those in the normal controls (P 0.05). In the patients, the mRNA expression of RANTES negatively correlated with the serum level of IgE and ECP (P

Objective To investigate the expression of lymphocyte function-associated antigen-1 (LFA-1)on peripheral blood mononuclear cells(PBMCs)from patients with SLE and its relation to the occurrence and development of SLE.Methods PBMCS were obtained from 30 patients with SLE and 24 normal human controls.Atier labeled with anti-CD3-FITC and anti-CD11 a-PE,PBMCS were detected for the expression of CD11a by flow cytometric analysis.Results The positivity rate of CD11a was significantly higher in patients with SLE and those with active SLE than in the normal controls (73.74%±7.89%and 77.11%±7.46%vs 68.21%±4.58%.both P＜0.05).Furthermore,increased positivity rate of CD11a was observed in patients with active SLE compared with those with stable SLE (77.11%±7.46%vs 69.33%±6.27%,P＜0.05).but there was no significant difieFence between the latter group and normal controls(P＞0.05).In addition.the expression level of CD11a was positively correlated with SLE disease activity index (r=0.64,P＜0.0 1)in patients.Conclusion The overexpression of LFA-1 may take part in the occurrence of SLE and correlate with the activity of SLE.
