Objective:To investigate whether caffeic acid phenethyl ester (CAPE) would improve peritoneal dialysis (PD)-associated peritoneal fibrosis by alleviating oxidative stress through activating nuclear factor erythroid-2-related factor 2 (Nrf2)/heme oxygenase-1 (HO-1) pathway.Methods:Thirty-two male Sprague-Dawley rats were randomly divided into four groups by the random number table: control (CON) group (0.9% normal saline 20 ml/d intraperitoneal injection), CAPE group (0.9% normal saline 20 ml/d+CAPE 10 mg·kg -1·d -1 intraperitoneal injection), PD group [4.25% glucose peritoneal dialysis fluid (PDF) 20 ml/d intraperitoneal injection with lipopolysaccharide 0.6 mg/kg intraperitoneal injection at day 1, 3, 5 and 7], and PD+CAPE group (CAPE 10 mg·kg -1·d -1 intraperitoneal injection in addition to PD group), with 8 rats per group. On day 28, rats were euthanized after peritoneal equilibration test, and then the parietal peritoneum and omentum were collected for follow-up tests. To further investigate the mechanism, primary peritoneal mesothelial cells (PMCs) of rats were isolated and cultured. The PMCs were stimulated with 2.5% glucose PDF and added with 5 μmol/L CAPE intervention. The Nrf2 inhibitor (ML385) was used to identify whether CAPE protected PMCs from PDF by activating the Nrf2/HO-1 pathway. Histopathological staining was used to detect structural changes of the peritoneum, and immunohistochemical analysis was performed on cleaved caspase-3, Bax, α-smooth muscle actin (α-SMA), fibronectin (FN), and typeⅠ collagen (Col-Ⅰ) protein. Western blotting was used to detect the protein expression of α-SMA, FN, transforming growth factor-β1 (TGF-β1), HO-1 and nuclear Nrf2 (N-Nrf2). The apoptosis detection kit was used to detect apoptosis and flow cytometry was used to detect reactive oxygen species (ROS) in PMCs. The malondialdehyde (MDA) and superoxide dismutase (SOD) activity detection kit were used to detect MDA content and SOD activity. Cell immunofluorescence was used to analyze the protein expression of Nrf2 in PMCs. Results:Compared with the CON group, the PD group had thicker peritoneum, and the expression levels of cleaved caspase-3, Bax, α-SMA, FN, Col-Ⅰand MDA in peritoneum were significantly higher, while HO-1, N-Nrf2 protein expression and SOD activity were lower (all P<0.05). Compared with the PD group, the parietal peritoneum morphology of CAPE+PD group was improved, accompanied by reduced cleaved caspase-3, Bax, α-SMA, FN, Col-Ⅰ protein expression, and MDA content, while N-Nrf2, HO-1 protein expression, and SOD activity were higher (all P<0.05). Compared with the CON group, the PD group had significantly lower ultrafiltration volume and higher peritoneal permeability (both P<0.05). After CAPE intervention, the peritoneal transport function of the rats was significantly improved ( P<0.05). In cultured PMCs, PDF inhibited nuclear translocation of Nrf2 and protein expression of HO-1, and upregulated intracellular ROS level. In addition, PDF increased cell apoptosis and the protein expression levels of α-SMA, TGF-β1 and FN (all P<0.05). CAPE activated nuclear translocation of Nrf2, increased HO-1 protein expression, downregulated intracellular ROS level, and partially reversed PDF-induced cell apoptosis and epithelial- mesenchymal transition (all P<0.05). The protective effects of CAPE on PMCs were partially abolished by ML385 (all P<0.05). Conclusions:CAPE can reduce PD-induced PMCs apoptosis and epithelial-mesenchymal transition by attenuating oxidative stress, and significantly improve peritoneal fibrosis and ultrafiltration function. The beneficial effects of CAPE on peritoneum are related to activation of Nrf2/HO-1 pathway.

Objective:To explore the dynamic changes of inflammatory cytokines and T lymphocyte activation in the peripheral blood of human immunodeficiency virus (HIV)/acquired immunodeficiency syndrome (AIDS) patients during anti-retroviral therapy (ART).Methods:Two hundred and six HIV/AIDS patients with ART at clinic of the Department of Infectious Diseases in Second Xiangya Hospital, Central-South University between January 2017 and December 2019 were selected as HIV infection group. They were followed up regularly and the blood samples before treatment and at month 6, month 12, month 24 of treatment were collected. Meanwhile, 52 healthy cases were enrolled in the healthy control group and their blood samples were collected. Enzyme-linked immunosorbent assay was used to detect the plasma concentrations of interleukin (IL)-6, hypersensitive C-reactive protein (hsCRP) and tumor necrosis factor (TNF)-α. Flow cytometry was used to detect the CD3 + CD4 + T lymphocytes count and the percentage of CD4 + CD38 + T lymphocytes and CD8 + CD38 + T lymphocytes in the peripheral blood mononuclear cells. Plasma HIV RNA viral load was determined using a quantitative real-time polymerase chain reaction technique. Statistical methods used paired t test and Pearson correlation analysis. Results:The concentrations of IL-6, hsCRP and TNF-α in HIV infection group were (13.42±2.35) pg/mL, (4 012.46±1 012.35) μg/L and (51.78±11.32) μg/L, respectively, which were higher than those in healthy control group ((6.14±0.78) pg/mL, (707.21±305.76) μg/L and (19.01±6.48) μg/L, respectively). The differences were all statistically significant ( t=12.56, 16.79 and 13.45, respectively, all P<0.001). They decreased gradually after initiation of ART in HIV infection group, and returned to normal levels at month 24 of ART. CD3 + CD4 + T cells count was (256.00±65.32)/μL and HIV RNA viral load was (4.467±4.244) lg copies/mL before ART in HIV infection group, which were negatively correlated ( r=-0.625, P=0.041). The percentages of CD8 + CD38 + T lymphocytes before treatment and at month 12 or month 24 of treatment in HIV infection group were higher than those in healthy control group. The differences were all statistically significant ( t=3.85, 6.84 and 2.57, respectively, all P<0.050). The percentage of CD8 + CD38 + T lymphocytes was positively correlated with HIV RNA viral load before ART ( r=0.768, P=0.026). The percentages of CD4 + CD38 + T lymphocytes before treatment and at month 12 or month 24 of treatment in the HIV infection group were lower than those in the healthy control group, and the differences were all statistically significant ( t=6.80, 1.10, and 2.11, respectively, all P<0.050). Conclusions:HIV infection could not only cause insufficiency in immune system, but also abnormal activation of immune system, which could get better gradually with ART.

Objective:To compare the efficacy of the combination of abidol, lopinavir/ritonavir plus recombinant interferon α-2b (rIFNα-2b) and the combination of lopinavir/ritonavir plus rIFNα-2b for patients with COVID-19 in Zhejiang province.Methods:A multicenter prospective study was carried out to compare the efficacy of triple combination antiviral therapy and dual combination antiviral therapy in 15 medical institutions of Zhejiang province during January 22 to February 16, 2020. All patients were treated with rIFNα-2b (5 million U, 2 times/d) aerosol inhalation, in addition 196 patients were treated with abidol (200 mg, 3 times/d) + lopinavir/ritonavir (2 tablets, 1 time/12 h) (triple combination group) and 41 patients were treated with lopinavir/ritonavir (2 tablets, 1 time/12 h) (dual combination group). The patients who received triple combination antiviral therapy were further divided into three subgroups: <48 h, 3-5 d and >5 d according the time from the symptom onset to medication starting. The therapeutic efficacy was compared between triple combination group and dual combination group, and compared among 3 subgroups of patients receiving triple combination antiviral therapy. SPSS 17.0 software was used to analyze the data.Results:The virus nucleic acid-negative conversion time in respiratory tract specimens was (12.2±4.7) d in the triple combination group, which was shorter than that in the dual combination group [(15.0±5.0) d] ( t=6.159, P<0.01). The length of hospital stay in the triple combination group [12.0 (9.0, 17.0) d] was also shorter than that in the dual combination group [15.0 (10.0, 18.0) d] ( H=2.073, P<0.05). Compared with the antiviral treatment which was started within after the symptom onset of in the triple combination group, the time from the symptom onset to the viral negative conversion was 13.0 (10.0, 17.0), 17.0 (13.0, 22.0) and 21.0 (18.0, 24.0) d in subgroups of 48 h, 3-5 d and >5 d, respectively ( Z=32.983, P<0.01), while the time from antiviral therapy to viral negative conversion was (11.8±3.9), (13.5±5.1) and (11.2±4.3) d, respectively( Z=6.722, P<0.05). Conclusions:The triple combination antiviral therapy of abidol, lopinavir/litonavir and rIFNα-2b shows shorter viral shedding time and shorter hospitalization time, compared with the dual combination antiviral therapy; and the earlier starting triple combination antiviral therapy will result in better antiviral efficacy.
