Objective:To investigate the clinical manifestations, laboratory and imaging features, treatment and prognosis of systemic lupus erythematosus (SLE) with primary sclerosing cholangitis (PSC).Methods:This is a retrospective case series study describing the clinical, laboratory and imaging manife-stations, treatment and prognosis of 3 SLE patients with PSC. The related literatures were reviewed.Results:In total, 10 patients were included. SLE with PSC, with an average age of (43±17) years old, was more common with hematological and renal involvement, jaundice and arthralgia, positive anti-double-stranded DNA (anti-dsDNA) antibody, hypocomplementemia, elevated erythrocyte sedimentation rate (ESR) and abnormal liver function with predominately elevated alkaline phosphatase (ALP). The classic magnetic resonance cholangio-pancreatography (MRCP) features of PSC include multifocal strictures, beading and areas of dilatation involving the intra- and/or extrahepatic bile ducts. The treatment included glucocorticosteroids, immunosup-pressants and ursodeoxycholic acid (UDCA), and some patients required biliary drainage. Most patients had a good prognosis.Conclusion:Although PSC is rare, attention should be paid to SLE patients with abnormal liver function, especially with elevated ALP, in order to differentiate from PSC.

Objective:To explore the levels of programmed death receptor 1 (PD-1) and lymphocyte activating gene 3 (LAG-3) in the immune microenvironment of diffuse large B-cell lymphoma (DLBCL), their relationship with clinicopathological features, and their impact on prognosis.Methods:The tumor tissue sections and formaldehyde fixed paraffin embedded tissues from 174 DLBCL patients diagnosed at the First Affiliated Hospital of Xinjiang Medical University from February 2012 to August 2017 were retrospectively collected. The tissue chips were prepared, and the immunohistochemistry (IHC) method was used to detect the expressions of PD-1 and LAG-3 proteins in tumor infiltrating lymphocytes (TIL) of tissue chips [including whether they were positive (positive for IHC score 1-9 points, negative for 0 point) and expression level (high expression was 4-9 points on IHC score, low expression was 0-3 points)]. The relationship between the expression levels of PD-1 and LAG-3 and the clinicopathological characteristics of patients was analyzed. Spearman correlation coefficient was used to analyze the correlation between the expression levels of PD-1 and LAG-3. Kaplan-Meier method was used to draw overall survival (OS) and progression free survival (PFS) curves of patients with different expression levels of PD-1 and LAG-3, and log-rank test was used for comparison between the groups. Univariate and multivariate Cox proportional hazards models were used to analyze the influencing factors of OS and PFS in patients.Results:Of the 174 DLBCL patients, 95 (54.6%) were male and 79 (45.4%) were female; the median age was 60 years old (5-87 years old). The proportions of patients with PD-1 and LAG-3 positive in TIL of tumor tissues were 79.3% (138/174) and 78.8% (137/174), and the proportions of patients with high expression were 35.6% (62/174) and 37.9% (66/174), respectively. Among patients with bone marrow involvement, the proportion of patients with high expression of PD-1 [62.5% (15/24) vs. 32.5% (39/120), P= 0.006], the proportion of patients with high expression of LAG-3 [54.2% (13/24) vs. 32.5% (39/120), P= 0.050] were higher than those without bone marrow involvement. The expression levels of PD-1 and LAG-3 were not associated with gender, age, clinical stage, international prognostic index score, functional status (PS) score, lactate dehydrogenase level, whether there were B symptoms, whether it was intranodal, tumor length, whether it was germinal center B cell type, number of extranodal involvement sites, and whether it was treated with R-CHOP regimen (all P > 0.05). There was a positive correlation between PD-1 and LAG-3 expression levels in TIL of tumor tissues ( r = 0.202, P = 0.008). Multivariate Cox regression analysis showed that PS score (>2 points vs. ≤2 points: HR = 5.458, 95% CI 2.082-14.307, P = 0.001), R-CHOP regimen treatment (no vs. yes: HR = 2.181, 95% CI 1.086-4.379, P = 0.028) were independent influencing factors of OS, and PS score (>2 points vs. ≤2 points: HR = 3.913, 95% CI 1.579-9.698, P = 0.003), R-CHOP regimen treatment (no vs. yes: HR = 2.609, 95% CI 1.412-4.819, P = 0.024), LAG-3 expression level (low expression vs. high expression: HR = 0.531, 95% CI 0.283-0.995, P = 0.048) were independent influencing factors of PFS. There were no statistical differences in PFS and OS between patients with high and low PD-1 expression levels in TIL (both P > 0.05). PFS and OS in patients with high LAG-3 expression were worse than those in patients with low expression (both P < 0.05). OS in patients with high expressions of PD-1 and LAG-3 was worse than that in patients with low expressions of PD-1 and LAG-3 ( P = 0.044). Conclusions:The expression levels of PD-1 and LAG-3 in TIL of DLBCL patients' tumor tissues are related to bone marrow involvement, which are not related to most other clinicopathological features, and the prognosis of patients with high expressions of PD-1 and LAG-3 is poor.

As the key of colleges and universities and medical career,the affiliated hospital's clinical department is the core of its development.In the new era,strengthening the mechanism of party branch participating in the decision-making of clin-ical departments is an inevitable requirement for implementing the party's leadership and strengthening hospital management.The Party branch of the affiliated hospital of the university has the"dual"attribute,through the establishment of the"core group"of the party branch to participate in decision-making in the clinical business department,the establishment of an efficient decision-making platform,the construction mechanism of supporting rules of procedure and supervision measures to realize its function,the in-depth analysis of management challenges and the improvement of countermeasures,in order to create a new way and a new mechanism of the party branch decision-making,and promote the deep integration of party building and business.

OBJECTIVE To provide reference for clarifying improvement effects of Anemarrhena asphodeloides on sepsis- induced myocardial injury and potential material basis. METHODS Water extract of A. asphodeloides was extracted by thermal reflux method. Total xanthone and total saponins in A. asphodeloides were separated by macroporous adsorption resin. The mice model of sepsis-induced myocardial injury was established by intraperitoneal injection of lipopolysaccharide. The effects of the location of three extraction fractions and the monomers of A. asphodeloides as mangiferin， timosaponin AⅢ and timosaponin BⅡ on the survival rate of the model mice were explored. HE staining was used to observe the effects of mangiferin， timosaponin AⅢ and timosaponin BⅡ on myocardial morphology in model mice. The effects of mangiferin on mRNA expressions of inflammatory cytokines [interleukin-6 （IL-6）， IL-1β and tumor necrosis factor-α （TNF-α）] and the level of reactive oxygen species （ROS） in myocardial tissue of model mice were detected. RESULTS Compared with the model group， the survival rate of mice in the intervention group of total xanthone， total saponins and water extract was increased to different extents， especially total xanthone fraction. Mangiferin， timosaponin AⅢ and timosaponin BⅡcould improve the degree of myocardial cell swelling and muscle bundle arrangement disorder in model mice， especially mangiferin. Compared with model group， mRNA expressions of IL-6， IL- 1β and TNF- α， ROS level in myocardium of mice after mangiferin intervention were decreased to different extents. CONCLUSIONS The different extraction fractions of A. asphodeloides can improve survival rate of mice with sepsis-induced myocardial injury， especially total xanthone fraction. Mangiferin is the best among the three monomers of A. asphodeloides to improve sepsis-induced myocardial injury， which may play a role in anti-sepsis myocardial injury by anti-inflammation and antioxidantion.
