OBJECTIVE: To observe the expression of Fas receptor and ligand in human laryngocarcinoma cell line, Hep-2 and to investigate the possible mechanism of immune escape through Fas/FasL pathway in Hep-2 cell. METHOD: The mRNA and protein expressions of Fas and FasL in Hep-2 cell were analyzed by RT-PCR and flow cytometry (FCM). Growth curve of Jurkat cell was drawer based on the results of MMT, and apoptosis of Jurkat cell were determined by FCM and Hoechst 33342 staining after coculturing with Hep-2 cell. RESULT: The expressions of Fas and FasL in Hep-2 cell line were evaluated by flow cytometry and the mean fluorescence intensity were (32.91 +/- 5.6) and (25.57 +/- 7.1) respectively. After coincubation with Hep-2 cell (1 X 10(9)/L), the apoptosis rates of Jurkat cells were (38.95 +/- 0.11) % and (13.28 +/- 0.14) %, with planting concentration at 1 x 10(8)/L and 5 x 10 (8)/L respectively. In contrast, the apoptosis rate of Jurkat cultured separately was (7.53 +/- 0.17)%. The proliferation of Jurkat cell was obviously inhibited after coculture. However, the apoptosis rate was significantly decreased after adding neutralizing antibody of FasL. CONCLUSION Laryngocarcinoma cell could induce apoptosis of T lymphocytes through Fas-FasL system, thus it provided a potential mechanism to escape from immune surveillance of host.

Objective To study the effect of age-related white matter changes (ARWMC) on first symptomatic ischemic stroke events in the oldsters. Methods For the prospective study, a total of 368 eligible oldsters were enrolled in the study from January 2010 to August 2012. The degrees of ARWMC were assessed by ARWMC scale;according to the scores, they were divided into non ARWMC group, mild-moderate ARWMC group and severe ARWMC group. The patients were followed up once every 3 months. The clinical endpoint events and time (first symptomatic ischemic stroke, myocardial infarction and all-cause death) were recorded. Analyses of variance and Chi-square test were used to compare the differences of clinical data among the 3 groups. COX regression was used to assess the risk differences of first symptomatic ischemic stroke in the oldsters of three groups. Results After an average of follow-up for 48.7 months, 50 participants (13.6％) had first symptomatic ischemic stroke;25 (25.8％) were categorized as the severe ARWMC group, 22 (10.9％) were as the mild-medium group, and 3 (4.4％) were as the non ARWMC group. Among the three groups, the differences in age, history of hypertension, systolic blood pressure, incidence of clinical endpoint events and first symptomatic ischemic stroke, and follow-up time of endpoint events were statistically significant (P<0.05); patients from the severe ARWMC group were the oldest, and had the longest history of hypertension, the highest systolic blood pressure, the highest incidence of clinical end events and first symptomatic ischemic stroke, and the shortest follow-up period for clinical end events. COX regression analysis showed that the risk of first symptomatic ischemic stroke in the severe ARWMC group was about 8 times higher than that in the non ARWMC group (hazard ratio=9.012, 95％CI: 2.310-35.154, P=0.002). Conclusion In oldsters, severe ARWMC often accompany hypertension history and poor blood pressure controll, and it is an independent and serious risk factor for long-term first symptomatic ischemic stroke.

ObjectiveThe bioinformatics method was used to screen ferroptosis differential genes （FRGs） closely related to ulcerative colitis （UC）， and animal experiments were conducted to verify whether the mechanism of Xiezhuo Jiedu recipe in treating UC is related to the regulation of ferroptosis. MethodThe differentially expressed genes （DEGs） of colonic mucosa tissue of UC patients were obtained from the GEO database， and the intersection of the genes with ferroptosis genes was used to obtain FRGs. The core FRGs were obtained by cluster analysis， minimum absolute contraction and selection operator （LASSO） regression， and receiver operating characteristic curve （ROC） curve analysis. In animal experiments， the UC mouse model was prepared by making the mouse freely drink 2.5% dextran sodium sulfate （DSS）. Xiezhuo Jiedu recipe and mesalazine were given by gavage for seven days， and the inflammatory infiltration of colonic mucosa was observed by hematoxylin-eosin （HE） staining. Real-time fluorescence quantitative polymerase chain reaction （Real-time PCR） was used to detect the mRNA expression levels of E3 ubiquitin ligase （FBXW7）， zinc finger protein （ZFP36）， solute carrier family 7 member 11 （SLC7A11）， and Toll-like receptor 4 （TLR4） in colon tissue. The protein expression levels of FBXW7， ZFP36， SLC7A11， and TLR4 in colon tissue were detected by Western blot. ResultDataset GSE87466 was screened from the GEO database， and its intersections with the ferroptosis gene were analyzed to obtain 21 FRGs. After cluster analysis， LASSO regression， and ROC analysis， core FRGs （FBXW7， ZFP36， SLC7A11， and TLR4） were obtained. Immunoinfiltration analysis showed significant differences in the expression of initial B cells， M1 macrophages， plasma cells， and M2 macrophages in the colonic mucosa tissue of UC mice， and there was a significant correlation between core FRGs and these immune cells. Further animal experiments showed that the colonic mucosa tissue of mice in the model group was disorganized and infiltrated by a large number of inflammatory cells. The inflammation of the colonic mucosa tissue of mice in each group was relieved to varying degrees after treatment with Xiezhuo Jiedu recipe and mesalazine， while the colonic mucosa tissue of mice in the high-dose group of Xiezhuo Jiedu recipe showed almost no inflammatory changes. Compared with the normal group， the protein and mRNA expressions of FBXW7， ZFP36， SLC7A11， and TLR4 in the model group were significantly increased， and the expression of core FRGs in colonic mucosa tissue of mice in all groups was significantly down-regulated after treatment with Xiezhuo Jiedu recipe and mesalazine. ConclusionFBXW7， ZFP36， SLC7A11， and TLR4 are ferroptosis genes closely related to the pathogenesis of UC， and Xiezhuo Jiedu recipe can significantly alleviate colonic mucosa inflammation in mice by down-regulating core ferroptosis genes.
