· AIM: To investigate the expression and the possible implication of CD40/CD40L costimulatory molecules in erythema nodosum of patients with Beh(c)et's disease.· METHODS: Sampling was done from erythema nodosum of 5 patients with Beh(c)et's disease and normal skin of 2 healthy individuals. Immunohistochemical staining was performed to examine the expression of CD4, CD8, CD19, CD68, HLA-DR,CD40 and CD40L molecules in the obtained tissues.· RESULTS: Approximately 90% of epidermic cells in erythema nodosum expressed CD40 molecule. In the dermis and subcutaneous tissue, a significantly increased number of CD4+Tcells, CD8+Tcells, CD19+cells, CD68+cells, HLA-DR+cells,CD40L+cells, and CD40+cells were observed in the erythema nodosum as compared with that in normal skin. Double staining showed that CD40L molecules were expressed on 45% of CD4+T cells. CD40 molecules were expressed on 100% CD68+ cells and 59.2% of HLA-DR+cells respectively.· CONCLUSION: A number of CD40/CD40L costimulatory molecules are upreguiated in the erythema nodosum of patients with Behcet's disease.

Objective To investigate the effects of heat-killed Staphylococcus aureus (HKSA) on the apoptosis and expression of iNOS and IL-1β in THP-1 monocytes in the presence of high concentration of glucose.Methods THP-1 cells were cultured in medium containing 25.0 mmol/L(HG) or 5.5 mmol/L (LG,control) D-glucose for 12 h-8 d.The THP-1 cells cultured for 6 d were extracted on the 0-48 h with or without HKSA,then apoptosis and expression of iNOS and IL-1β were examined.Apoptosis was analyzed by flow cytometry and expressions of IL-1β and iNOS were quantitated by real-time PCR.Results The expression of iNOS and IL-1β in THP-1 monocytes was increased significantly in the presence of high concentration of glucose for 12-48 h(P<0.05),reaching the highest level at 24 h and returned to baseline after 4 d.The expression was significantly lower than that of control after 4-6 d.Apoptosis rate was also increased significantly after 48 h to 4 days.HKSA infection enhanced apoptosis,but inhibited the expression of iNOS and IL-1 β in the presence of high concentration of glucose.The expression of iNOS and IL-1β increased significantly at 6 h(P<0.01),reaching the highest level at 12 h,but the levels were significantly lower than those in control groups (P<0.05).Conclusion These data suggest that high concentration of glucose can interfere with the anti-bacterial function of monocytes by reducing their expression of iNOS and IL-1β and enhancing their apoptosis.

Rivaroxaban is one of the new oral anticoagulants (NOAC) for preventing stroke and systemic embolism in patients with non-valvular atrial fibrillation. It has clear pharmacokinetic parameters, stable plasma concentration, less drug-drug interaction and higher compliance of patients. However, the discrepancy of pharmacokinetics between individuals and drug-induced hemorrhage events frequently occur clinically, therefore the association of gene polymorphism with drug metabolism has become a research hotspot. This article reviews the research progress on pharmacokinetic characteristics of rivaroxaban and its relationship with gene polymorphism, to provide a reference for the individualized rational use of rivaroxaban.

BACKGROUND: Henoch-Schonlein purpura (HSP) is an immune complex-mediated disease predominantly characterized by the deposition of circulating immune complexes containing immunoglobulin A (IgA) on the walls of small vessels. Although the pathogenesis of HSP is not yet fully understood, some researchers proposed that B-cell activation might play a critical role in the development of this disease. OBJECTIVE: To investigate the serum levels of visfatin (pre-B-cell colony-enhancing factor), B-cell-activating factor (BAFF), and CXCL13, and to analyze their association with disease severity. METHODS: The serum levels of visfatin, BAFF, and CXCL13 were measured by using a double-antibody sandwich enzyme-linked immunosorbent assay (ELISA) in 43 patients with HSP and 45 controls. The serum levels of IgA anticardiolipin antibodies (ACA) were detected by using a double-antigen sandwich ELISA. RESULTS: Levels of visfatin but not BAFF and CXCL13 were significantly elevated in the sera of patients with HSP in the acute stage, and restored to normal levels in the convalescent stage. Furthermore, serum levels of visfatin were significantly higher in patients with HSP having renal involvement than in those without renal involvement. Serum levels of visfatin were correlated with the severity of HSP and serum concentration of ACA-IgA. CONCLUSION: We show for the first time that the serum levels of visfatin are abnormally elevated in patients with HSP. Visfatin may be associated with the pathogenesis of HSP.

Objective: To evaluate the prognostic value of kinetic changes in minimal residual disease (MRD) status, as well as its relationship with risk stratification, therapeutic response and treatment in patients with newly-diagnosed multiple myeloma (MM) . Methods: A total of 135 patients with newly-diagnosed MM were screened, and 105 patients who achieved VGPR or more as the best responses were included into this study. The MRD status was determined by multiparameter flow cytometry (MFC) at multiple intervals after two cycles of treatment until clinical relapse, death, or last follow-up. The statistical methods included Kaplan-Meier analysis, Cox regression, etc. Results: ①In all 135 patients, 57.8% (78/135) patients achieved MRD negativity (MRD(-)) after treatment. In 105 patients who achieved VGPR and thus included in this study, the MRD(-) rate was 72.4% (76/105) , with a median interval of 3 months from starting treatment to achievement of MRD(-) status. ②The 2-year PFS rate of patients with MRD(-) status was significantly higher than that of MRD(+) status (62.2% vs 41.3%, P=0.001) , while MRD persistence (MRD(+)) was an independent factor for poor prognosis (multivariate analysis for PFS: P=0.044, HR=3.039, 95%CI 1.029-8.974) . ③Loss of MRD(-) status (i.e., MRD reappearance) showed inferior outcomes compared with MRD sustained negative ones, the PFS was 18 months versus not reach (P<0.001) and the OS was not reach for both (P=0.002) . ④The 2-year PFS and OS rates of patients with duration of MRD(-)status≥12 months were significantly higher than those of the control group (PFS: 77.7% vs 36.7%, P<0.001; OS: 96.4% vs 57.9%, P<0.001 respectively) . Duration of MRD(-) status was associated with a marked reduction in risk of relapse or death (univariate analysis for PFS: P<0.001, HR=0.865, 95%CI 0.815-0.918; for OS: P=0.001, HR=0.850, 95%CI 0.741-0.915 respectively) . ⑤Moreover, even in patients carrying high-risk cytogenetic abnormalities (CA) or ineligible for ASCT, MRD negativity remained its prognostic value to predict PFS (high-risk CA medianPFS: not reach vs 19 months, P=0.006; ineligible for ASCT medianPFS: not reach vs 25 months, P=0.052 respectively) . ⑥Last, treatment with the bortezomib-based regimens contributed to prolonged MRD(-) duration (median MRD(-) duratio: 25 months vs 10 months, P=0.034) . Conclusion: Our findings supported MRD(+) status as an independent poor prognostic factor in MM patients, which implicated that duration of MRD(-) status also played a significant role in evaluation of prognosis, while loss of MRD(-)status might serve as an early biomarker for relapse. Therefore, monitoring of MRD kinetics might more precisely predict prognosis, as well as guide treatment decision, especially for when to start retreatment in relapsed patients.

OBJECTIVETo analyze and study types, infections routes and causes of global pathogenic microorganisms laboratory-acquired infections cases reported in the literatures from 2000 to 2009 and to discuss prevention and control strategies.
METHODS(1) Pathological observation of hepatic specimens: hepatic tissue pathogenic microorganisms laboratory-acquired infections. Methods PubMed, Embase, Biosis and Webs of Science covering SCIE, SSCI, CPCI-S and CPCI-SSH are chosen as data sources, "laboratory-acquired (associated) infections" are searched as the key words to search laboratory-acquired infections literature published from 2000 to 2009, from which information and data are accessed to be collected, analyzed and researched.
RESULTSThere are 19 species of pathogenic microorganisms causing laboratory-acquired infections in the last 10 years, including 15 species of bacteria, accounting for 78.9%; 4 species of virus, accounting for 21.1%. There are 83 cases reported, of which there are 60 bacterial cases, accounting for 72.3%; and 23 virus cases, accounting for 27.7%. Ingestion and inhalation are main routes of infections, respectively accounting for 32.5% and 31.3%, which are mainly due to accidents, accounting for 47.0%.
CONCLUSIONIn recent years, pathogenic microbiology laboratory-acquired infections continue to occur, and it is mainly due to accidental infections, which expose laboratory workers' low sense of safety and deficient operation methods. Laboratory staff should strengthen their senses of safety and comply with safe operation procedures, which are still the key to prevent laboratory-acquired infections.

Objective To analyze the spatial point pattern distribution characteristics of hemorrhagic fever with renal syndrome (HFRS) in Jingzhou city, Hubei province during the two seasons spring- summer and autumn-winter of 2017, to discuss its high incidence area and reason, and to provide basis for the resource allocation of public health. Methods The analytical data was collected from Infectious Disease Reporting Information System in China, and the spring-summer season was from March to August of 2017, while the autumn-winter was from the September of 2017 to the February of 2018. The Ripley's K-function and kernel density estimation were applied to analyze the spatial point pattern distribution and compare the distribution characteristics of spatial point pattern between the two seasons. Results In 2017, 133 cases of HFRS were reported in Jingzhou city, including the spring- summer and autumn-winter two pick incidences. The strongest aggregation distance was 17.77km in spring-summer season, and 14.40 km in autumn-winter season. The spatial gathering center was located in the north of Jianli County in spring-summer, and it moved to the south of Jiangling County and Shashi District in autumn-winter. Conclusions The key areas for the prevention and control of HFRS in Jingzhou City are Jiangling County, the southern part of Shashi District and the northern part of jianli county. The key groups are the residents of the urban-rural junction in the southern part of Shashi City, residents along the route of large-scale projects, and farmers engaged in agricultural planting or crayfish breeding in the gathering areas.

BACKGROUNDAnomalous origin of the left coronary artery from the pulmonary artery (ALCAPA) is a rare congenital heart anomaly. We aimed to illustrate the clinical features and long-term prognosis of patients with ALCAPA.
METHODSTwenty three patients (13 males and 10 females, ages ranging from 2.5 months to 65 years) identified as ALCAPA in Beijing Anzhen Hospital from April 1984 to June 2009 were divided into two groups, based on the age of onset: group 1 (≤ 12 months, n = 16) and group 2 (> 12 months, n = 7).
RESULTSFifty six point three percent of patients in group 1 had been misdiagnosed as endocardial fibroelastosis (9/16), 18.8% as dilated cardiomyopathy (3/16) and 6.3% as myocardial infarction (1/16). Patients in group 2 were usually diagnosed as coronary heart disease, myocarditis, or patent ductus arteriosus. Electrocardiography in group 1 revealed abnormal Q waves with T wave inversion in leads I, avL, V(4)-V(6), especially in lead avL (deep and wide Q wave); but no specific manifestations in group 2. A higher percentage of patients in group 1 had cardiomegaly on chest radiograph (86.7% vs. 33.3%, P = 0.031), while pulmonary artery protrusion was more common in group 2 (26.7% vs. 83.3%, P = 0.046). Lower left ventricular ejection fraction (LVEF) was present in group 1 than in group 2 ((48.5 ± 11.5)% vs. (65.0 ± 6.1)%, P < 0.001). Apical ventricular aneurysm (62.5% vs. 0%, P = 0.007), enhanced echogenicity of papillary muscles (87.5% vs. 28.6%, P = 0.011) and endocardial thickening (93.8% vs. 14.3%, P < 0.001) were more frequent in group 1 than in group 2. The ratio of the proximal right coronary artery (RCA) diameter to the aortic root diameter exceeded 0.14 in all cases, more prominent in group 2 (0.26 ± 0.05 vs. 0.33 ± 0.03, P = 0.009). Increased coronary artery collaterals within the interventricular septum were detected in 18 patients (78.3%) by Doppler imaging. Twenty one patients underwent cardiac surgery, including left coronary artery (LCA) ligation (1/21), LCA ligation plus coronary artery bypass grafting (1/21), Takeuchi operation (7/21), and LCA reimplantation surgery (12/21). Four patients underwent concomitant mitral valve repair and one received mitral valve replacement. Aneurysm resection was performed in 3 cases. Six patients died in hospital after surgery, and the rest of the cohort had no overt symptoms during a follow-up period of 6 to 166 months. Their abnormal Q waves gradually regressed or disappeared, and the LVEF and left ventricle size returned to normal range with alleviation of mitral insufficiency.
CONCLUSIONSThe accurate diagnosis of ALCAPA can be made with serial diagnostic methods. ALCAPA can be successfully treated with several types of cardiac surgery, and surgeries of establishing two-coronary-artery circulation are the preferred operations nowadays, with good long-term prognosis.
