This study aims to clarify host factors of IFN treatment in the treatment of chronic hepatitis B (CHB) patients by screening the differentially expressed genes of IFN pathway CHB patients with different response to interferon (IFN) therapy. Three cases were randomly selected in IFN-responding CHB patients (Rs), non-responding CHB patients (NRs) and healthy participants, respectively. The human type I IFN response RT2 profiler PCR array was used to detect the expression levels of IFN-related genes in peripheral blood monocytes (PBMCs) from healthy participants and CHB patients before and after Peg-IFN-α 2a treatment. The results showed that more differentially expressed genes appeared in Rs group than NRs group after IFN treatment. Comparing with healthy participants, IFNG, IL7R, IRF1, and IRF8 were downregulated in both Rs and NRs group before IFN treatment; CXCL10, IFIT1, and IFITM1 were upregulated in the Rs; IL13RA1 and IFI35 were upregulated in the NRs, while IFRD2, IL11RA, IL4R, IRF3, IRF4, PYHIN1, and ADAR were downregulated. The expression of IL15, IFI35 and IFI44 was downregulated by 4.09 (t = 10.58, P < 0.001), 5.59 (t = 3.37, P = 0.028) and 10.83 (t = 2.8, P = 0.049) fold in the Rs group compared with the NRs group, respectively. In conclusion, IFN-response-related gene array is able to evaluate IFN treatment response by detecting IFN-related genes levels in PBMC. High expression of CXCL10, IFIT1 and IFITM1 before treatment may suggest satisfied IFN efficacy, while high expression of IL13RA1, IL15, IFI35 and IFI44 molecules and low expression of IFRD2, IL11RA, IL4R, IRF3, IRF4, PYHIN1 and ADAR molecules may be associated with poor IFN efficacy.
Objective To examine the levels of interferon-gamma; (INF-gamma;), tumor necrosis factor-alpha; (TNF-alpha;) and interleukin-6(IL-6) in serum of patients with acute uveitis before and after treatment, and to explore the possible roles of those cytokines in the initiation and progression of the uveitis. Methods A series of 75 patients with acute uveitis,and 30 healthy persons from our hospital were investigated. The levels of INF-gamma;, TNF-alpha; and IL-6 in acute phase and convalescent phase were measured by the enzymelinked immunosorbent assay. Result The serum levels of INF-gamma;, TNF-alpha; and IL-6 in acute phase were significantly higher than that of the convalescent phase and the healthy controls (F=65.805/50.418/155.381, P=0.000). A significant negative correlation was found between the serum levels of INF-gamma;, TNF-alpha; and IL-6 in acute phase with their initial visual acuity(r=-0.656, -0.592 and -0.653, Plt;0.01). There was also a positive correlation among the serum levels of INF-gamma;, TNF-alpha; and IL-6(r=0.340, 0.467 and 0.338, Plt;0.05). Conclusions There are high serum levels of INF-gamma;, TNF-alpha; and IL-6 in patients with acute uveitis, and the cytokines levels were decreased after the treatment. The results suggested that the INF-gamma;, TNF-alpha; and IL-6 involved in initiation and progression of uveitis.

OBJECTIVE To study the influence and mechanism of gamma-IFN on fibroblasts in hypertrophic scars(HTS). METHODS The cultured fibroblastic cells were isolated from the hypertrophic scars of 10 patients. The fibroblasts were divided into two groups, one group was treated with gamma-IFN (100 U/ml, 5 days) and the other without gamma-IFN as control. The proliferative activity in both groups was investigated and compared by blood cytometer, the proportion of myofibroblast (MFB) and the ratio of apoptosis were examined and analysed between two groups by flow cytometry using alpha-smooth muscle actin (alpha-SMA) as marker. RESULTS The proliferative activity was downregulated with gamma-IFN. In gamma-IFN treated group, the differentiation of MFB were reduced and the decreasing ratio was 3.2% at the 2nd day and up to 10.5% at the 8th day, then it reduced gradually. The apoptosic ratio is 17.7% in gamma-IFN treated group, and is 10.9% in control group. The difference was statistically significant. CONCLUSION gamma-IFN could downregulate the proliferation of fibroblasts, decrease the differentiation of MFB and induce the apoptosis. It has beneficial effect in the treatment of hypertrophic scars(HTS).

ObjectiveTo observe effect of interferon-γ in preventing intestinal adhesion following abdominal surgery in rats.MethodsA total of 60 Wistar rats were selected, which were randomly divided into a sham operation (SO) group, model group, dexamethasone (DXMS) group, and interferon-γ group, then the interferon-γ group was randomly divided into a low, medium, and high concentrations subgroups. Except for the SO group, the laparotomies with file friction caecum were performed for all the other groups to establish the intestinal adhesion model. SO group and model group were intraperitoneally injected with saline for 4 mL/kg. The 10 mg/kg dexamethasone was injected into the abdominal cavity of rats in the DXMS group. The 7.5×104, 1.5×105, and 3.0×105 U/kg interferon-γ concentrations were injected into the abdominal cavity of rats in the low, medium, and high concentrations subgroups respectively. The Nair grading of cecum adhesion degree was assessed on the 8th day after the surgery, then the histopathological change was observed by the HE staining under the microscopy and the hydroxyproline content in the cecum tissue was detected.Results① The intestinal adhesion: Compared with the SO group, the intestinal adhesions occurred in all the other groups and the degrees of intestinal adhesions evaluated by the Nair grading were more significantly serious (P<0.05), which in the DXMS group and the medium and high concentrations of interferon-γ subgroups were significantly reduced (P<0.05) as compared with the model group, which in the high concentration of interferon-γ subgroup was significantly reduced (P<0.05) as compared with the DXMS group. ② The microscopic observation of histopathological results: Compared with the DXMS group, the high concentration of interferon-γ could effectively reduce the occurrence of fibrous tissue and inflammatory cell infiltration, the intestinal wall muscular layer structure was complete, a few inflammatory cells scattered in the infiltration. ③ The hydroxyproline content: The contents of hydroxyproline in the cecum tissue of the model group, DXMS group, and interferon-γ subgroups were significantly increased (P<0.05) as compared with the SO group, which of the DXMS group and medium and high concentrations of interferon-γ subgroups were significantly decreased (P<0.05) as compared with the model group, which of the high concentration of interferon-γ subgroup was significantly decreased (P<0.05) as compared with the DXMS group.ConclusionInterferon-γ has a preventive and therapeutic effect on postoperative intestinal adhesion and cecum injuries.
