Objective To explore the role of tumor necrosis factor (TNF-?) and endotoxin(LPS) in upper gastrointestinal bleeding in cirrhosis patients and the preventive and treatment mechanism of rhubarb. Methods 45 liver cirrhosis patients with upper gastrointestinal bleeding were treated with rhubarb, and its efficacy was compared with cemetidine's efficacy. Liver function, and serum levels of TNF-? and LPS were measured before and after the therapy. Results Patients’symptoms and liver function were improved, and serum levels of TNF-? and LPS significantly decreased after treated with rhubarb. Conclusions TNF-? and endotoxin might play an important role in upper gastrointestinal bleeding in cirrhosis patients. Rhubarb has protective and treatment effect on upper gastrointestinal bleeding in cirrhosis patients by reducing TNF-? and LPS release.

Objective To assess the clinical feature and diagnosis of diffuse hyperpigmentation with guttate depigmentation macules.Methods A retrospective study was carried out among 10 patients with diffuse hyperpigmentation with guttate depigmentation macules collected at the Institute of Dermatology,Chinese Academy of Medical Sciences and Peking Union Medical College from 2005 to 2012.The clinical manifestations,pathological findings and disease outcomes in these patients were analyzed.Results Of the 10 patients,6 were male,and 4 were female.The median age at onset was 7 years (range,4-25),and there were only 3 adult patients among these patients.None of the patients had a family history of pigmentary disturbance.Typical clinical manifestations included densely distributed,guttate hypopigmented macules arising on diffuse and uniform hyperpigmentation.Lesions could slowly spread over the body surface without the trend towards spontaneous regression.Pathologically,there was a slight increase in pigmentation of the epidermal basal layer,as well as melanins and melanophages scattered around blood vessels in the superficial dermis,with or without focal vacuolar degeneration of the basal cell layer.Conclusions Diffuse hyperpigmentation with guttate depigmentation macules,a rare pigmentary disturbance that clinically manifests as both hyperpigmentation and hypopigmentation and is pathologically characterized by postinflammatory hyperpigmentation,often affects children.Once the lesions occur,there is no trend towards regression.No effective treatment is available for this entity at present.

This study is to investigate the effect of downregulation histone deacetylases 1 (HDAC1) gene by the technology of RNA interference on the differentiation of HL-60 cells line. The optimal segment targeting HDAC1 gene was designed and transfected into HL-60 cells by Lipofectamine 2000. The HDAC1 mRNA and protein level were detected by RT-PCR and Western blotting. The morphologic change of HL-60 cells was detected by an optical microscope with Wright-Giemsa. Cell differentiation was tested by NBT reduction assay. Expression of CD13, CD33 and CD14 was measured by flow cytometry. The results indicated that HDAC1 mRNA and protein were markedly suppressed by the siRNA targeting HDAC1 in a concentration-dependent manner. HDAC1 siRNA promoted cell differentiation. HL-60 cells became more mature in morphology after transfected to HDAC1 siRNA at a concentration of 30-60 nmol x L(-1) for 24 h. NBT reduction ability of HDAC1 siRNA with 30 nmol x L(-1) was 0.31 +/- 0.09, compared with negative control (0.20 +/- 0.02) (t = -3.1, P < 0.01), and with 60 nmol x L(-1) was 0.25 +/- 0.02 in comparison with negative control (0.21 +/- 0.04) (t = -2.12, P < 0.05). But it has no change in HDAC1 siRNA > or = 120 nmol x L(-1). After transfection with 60 nmol x L(-1) HDAC1 siRNA to HL-60 cells, the expression of CD13 was (96.50 +/- 0.70)% in compared to siRNA-NC (3.39 +/- 0.68) % (t = 164.9, P < 0.000 5), CD33 was (66.73 +/- 0.50) % in compared to siRNA-NC (96.80 +/- 1.70) % (t = 43.4, P < 0.000 5). CD14 was (0.53 +/- 0.00) % by comparison with siRNA-NC (0.49 +/- 0.02) % (t = -0.97, P > 0.1). HDAC1 siRNA promoted cell differentiation in indicated concentration. HDAC1 might be one of the targets of gene therapy for leukemia.
