Objective: To study the effect of tripterygium wilfordii polyglycosidium (TWP) on atopie dermatitis (AD) by detecting the expression of IL-2,IL-4,IFN-γ and IL-IO mRNA. Methods: RT-RCR was used to detect the mRNA of IL-2,IL-4, IFN-γ and IL-10 in peripheral blood mononuelear cells (PBMC)of AD cultured with different concentrations of TWP.ResuRs:(1)The expression of IL-2 was significantly different between the high concentration group and other groups(P<0.05 or P<0.01 ), and between the control group and the middle concentration group (P<0.01). (2)The expression of IL-4 was significantly different between the three different concentration groups (P<0.01 ). (3) The expression of IFN-γmRNA was significantly different between the high concentration group and the control, the low, the middle concentration groups (P<0.05 or P<0.01 ). (4)There was no significant difference in expression of IL-10 mRNA between the high concentration group and the middle concentration group (P>0.05), there was significant difference among the other groups (P<0.05 or P<0.01).Conclusion: TWP can suppress the expression of IL-2, IL-4, IFN-γand IL-10 mRNA, but the low concentration of TWP can suppress the high-level expression of IL-4 and IL-10mRNA in vitro.

Abstract: Objective To explore the antiviral effect of baricitinib in the SARS-CoV-2 infection and influence on cytokine levels. Methods Calu-3 cells were infected with SARS-CoV-2 at MOI of 0.1, and the levels of inflammatory cytokines (IL-6, IL-8, TNF-α and IL-1β), interferon β (IFN-β) and interferon-stimulated gene, IFIT2 in the infected cells were analyzed by qRT-PCR methods. At the same time, Calu-3 cells were infected with SARS-CoV-2 (MOI=0.1) after being treated with baricitinib for 2 hours. Cells were collected at 0, 24, 36, and 48 hours, and analyzed for the mRNA of the above genes in the drug-treated and untreated groups. Results The mRNA levels of IL-6, TNF-a, IL-1β, IFN-β and IFIT2 in Calu-3 infected by SARS-CoV-2 cells were increased significantly. These cytokines were increased by nearly 100-fold post-infection 48 h compared with the control (P<0.000 1), and continued to increase with the infection time (P<0.001 or P<0.000 1). The increase of IL-8 mRNA level was not as significant as IL-6, TNF-α, IL-8, IL-1β, but it also showed a 2-4 folds increase. Baricitinib does not affect the level of viral RNA in Calu-3 cells after SARS-CoV-2 infection (P>0.05). However, baricitinib can significantly inhibit the up-regulation of IL-6 and TNF-α levels induced by SARS-CoV-2 infection (5.25-fold and 3.90-fold down-regulation, respectively, P<0.01), and has little effect on the levels of IL-8 and IL-1β . In addition, the drug could also significantly down-regulate the increase in IFN-β and IFIT2 levels caused by viral infection (10.51-fold and 90.78-fold down-regulation, respectively, P<0.000 1). Conclusions Baricitinib inhibits the release of inflammatory cytokines to some extent, but it drastically down-regulates the expression of interferons and interferon-stimulated genes (ISGs), and has limited antiviral effect on SARS-CoV-2. Considering that interferon signal pathways play important roles on viral infection, caution should be exercised when using baricitinib to treat COVID-19 patients.

Objective To analyze the efficacy,late complications and prognostic factors of post-op-erative radiotherapy for cervical cancer. Methods From Nov. 1999 to Feb. 2005,114 patients with cervi-cal cancer received adjuvant pelvic radiotherapy after radical hysterectomy and pelvic lymphadenectomy. The median age was 42.5 (24 to 72) years old. According to the FIGO staging system,6,51,18,26 and 13 pa-tients had stage ⅠA, Ⅰb1, Ⅰb2, ⅡA and ⅡBdisease. The pathological type was squamous cell carcinoma,ade-nocarcinoma, squamous-adenocarcinoma and undifferentiated carcinoma in 92,19,2 and 1 patients, respec-tively. The whole-pelvic external beam irradiation of 50 Gy (40 to 60 Gy) was given with 6 MV or 15 MV X-ray beams using four-field box technique. Eighty-one patients received intravaginal brachytherapy of 16 Gy (4 -30 Gy in 1 -6 fractions) 4 weeks after the beginning of radiotherapy, with the referrence point being at 0.5 cm under the vaginal mucosa. Eighty-seven patients received preoperative and/or concurrent chemother-apy. The survival and independent prognostic factors were analyzed by Log-rank method and Cox model. Results The median follow-up time was 26.0 (5 - 75) months. The overall survival rate, disease-free sur-rival rate and local control rate were 93.1%, 88.1% and 94.6% at 2-year, and 75.7%, 62.3% and 85.6% at 5-year,respectively. The independent prognostic factors were lymph node metastasis and positive surgical margin for overall survival, positive surgical margin for local control, and stage, uterine body invasion and positive surgical margin for disease-free survival. Sixteen patients ( 14% ) had distant metastasis, and the most common sites were the lung,inguinal region,bone,liver and brain. According to RTOG grading sys-tem, the incidence of late gastrointestinal side effects of grade 1,2 and 3 was 11.4%, 11.4% and 3.5%. The corresponding genitourinary side effects were 14.0% ,6.1% and 0.9%, respectively. The incidence of leg lymphedema was 7 % . Conclusions Post - operative radiotherapy can achieve good local control in cervical cancer with acceptable late side effects. Distant metastasis is the main cause of death.
