To investigate the relationships among plasma secreted frizzled-related protein ( sfrp) 5 level and body fat parameters, glucolipid metabolism, insulin resistance index, and inflammation. 89 subjects with normal glucose tolerance(NGT) and 87 patients with type 2 diabetes mellitus (T2DM) were enrolled and each group was divided into no-obese and obese subgroups. Obesity was defined as body mass index ( BMI)≥25 kg/m2 according to the World Health Organization -Western Pacific Region diagnostic criteria ( 2000 ) . Body fat parameters were measured and BMI, waist-hip ratio were evaluated, meanwhile, the levels of blood glucose-lipid parameters and fasting insulin were also determined. Insulin resistance index ( IR) was assessed by homeostasis model assessment ( HOMA) . The concentrations of plasma sfrp5 and interleukin 6 were detected by enzyme-linked immunosorbent assay. Plasma sfrp5 level in T2DM group was significantly lower than that in NGT group [(8. 35±3. 38 vs 11. 35±3. 69)ng/ml, P<0. 01]. The levels of plasma sfrp5 in subjects with obesity were also lower than those in subjects with no-obesity in both NGT and T2DM groups [(9. 46±2. 70 vs 13. 12±3. 62)ng/ml and(6. 70±2. 34 vs 10. 12±3. 45) ng/ml, both P<0. 01]. Plasma concentrations of sfrp5 in T2DM-obese group were significantly lower than that in NGT-obese group(P<0. 01). Correlation analysis showed that plasma sfrp5 levels were negatively correlated with waist-hip ratio, HbA1C, fasting insulin, triglycerides, waist circumference, fasting plasma glucose, interleukin 6, natural logarithm of HOMA-IR [ln(HOMA-IR)], and BMI(P<0. 01 or P<0. 05). Multiple linear regression showed that ln(HOMA-IR), BMI, triglycerides were independent related factors in influencing the levels of plasma sfrp5 (r2=0. 216, 0. 177, 0. 113, all P<0. 05). Plasma sfrp5 levels were decreased in obesity and T2DM subjects and were correlated with body fat disposition, glucose-lipid metabolism, insulin resistance and inflammation. Lack of sfrp5 may contribute to the pathophysiology of obesity and T2DM.

Objective:
To summarize the clinical characteristics, virological and histopathological features, clinical outcome of Epstein-Barr virus-positive lymphoproliferative disease (EBV+LPD) in children.
Methods:
The clinical and follow-up data of 13 children histopathologically diagnosed as EBV+LPD in the Department of Infectious Disease of Beijing Children's Hospital between January 2011 and December 2016 were summarized.
Results:
Of the 13 patients, 5 were males and 8 females. The median age of disease onset was 6.0 years (range 1.3 to 15.0 years). The median duration between disease onset and diagnosis was 3 months (range 1 to 24 months). All the 13 patients had fever, 9 cases had hepatosplenomegaly and lymphoadenopathy, 4 cases had only lymphoadenopathy, 7 cases had reduced peripheral blood cells, 7 cases had lung involvement, 3 cases had central nervous system involvement, 3 cases had cardiac involvement, 3 cases had intestinal involvement, 2 cases had skin involvement and 1 case had abdominal mass. All the 13 patients underwent whole blood EBV-DNA PCR examination and the copies ranged from 1×108/L to 1×1011/L. Pathology of lymph node confirmed 6 cases, skin pathology confirmed 2 cases, lung pathology, ileum mucosa pathology, liver pathology, abdominal mass pathology and bone marrow pathology confirmed 1 case each. Among 13 patients, 9 cases presented with EBV-positive T cell lymphoproliferative disease(EBV+ T-LPD), 2 cases with hydroa vacciniforme (HV) and 2 cases with EBV-positive diffuse large B-cell lymphoma (EBV+ DLBCL) . All the patients were followed up for 2 days to 65 months after discharge. Among 9 cases of EBV+T-LPD, 1 case died in a short time, 1 case died after evolved to T-cell lymphoma, 2 cases recovered after hematopoietic stem cell transplantation, 1 case recovered after the chemotherapy of hemophagocytic lymphohistiocytosis(HLH) 2004 protocol and 4 cases were stable now. Of 2 cases of HV patients, 1 case died after evolved to HV like lymphoma and the other still have symptoms. Among 2 cases of EBV+ DLBCL, 1 case died shortly after discharge and the other was still stable after chemotherapy.
Conclusions
Chronic recurrent fever, lymphadenopathy and hepatosplenomegaly are the most common clinical manifestations in children with EBV+LPD. Involvement of lung, central nervous system, intestinal tract, skin and other organs are also involved frequently. For children with chronic fever of unknown cause and accompanied by lymphadenopathy and (or) hepatosplenomegaly, EBV + LPD should be considered highly when the whole blood EBV-DNA load continues to increase significantly, early biopsy of the proliferative lesion should be performed to make a definite diagnosis. The prognosis of EBV + LPD is poor, and some evolve to lymphoma, hematopoietic stem cell transplantation is an effective way to treat this disease.

Xanthomonas albilineans (Ashby) Downson is a quarantine pest for importing plants to China that causes leaf scald bacterial disease on sugarcane. X. albilineans produces a potent phytotoxin/antibiotic called albicidin. As a pathogenic factor, albicidin causes typical white leaf stripes by inhibiting plastid DNA gyrase and disturbing chloroplast differentiation. Meanwhile, the antibacterial activity of albicidin gives X. albilineans a competitive advantage against rival bacteria during their colonization. Furthermore, albicidin has a rapid bactericidal activity against a variety of Gram-positive and Gram-negative pathogenic bacteria of human species at nanomolar concentrations, making it a potential antimicrobial drug for clinical application. This article reviews the advances of albicidin from the aspects of its molecular structure, traditional extraction methods, mechanism of action, biosynthetic genes and processes, chemical synthesis method and improvement, in order to provide insights into the prevention and treatment of the sugarcane leaf scald disease, and the development of new antibiotics.

Carotenoid cleavage dioxygenase (CCD) family is important for production of volatile aromatic compounds and synthesis of plant hormones. To explore the biological functions and gene expression patterns of CsCCD gene family in tea plant, genome-wide identification of CsCCD gene family was performed. The gene structures, conserved motifs, chromosome locations, protein physicochemical properties, evolutionary characteristics, interaction network and cis-acting regulatory elements were predicted and analyzed. Real time-quantitative reverse transcription PCR (RT-qPCR) was used to detect the relative expression level of CsCCD gene family members under different leaf positions and light treatments during processing. A total of 11 CsCCD gene family members, each containing exons ranging from 1 to 11 and introns ranging from 0 to 10, were identified. The average number of amino acids and molecular weight were 519 aa and 57 643.35 Da, respectively. Phylogenetic analysis showed the CsCCD gene family was clustered into 5 major groups (CCD1, CCD4, CCD7, CCD8 and NCED). The CsCCD gene family mainly contained stress response elements, hormone response elements, light response elements and multi-factor response elements, and light response elements was the most abundant (142 elements). Expression analysis showed that the expression levels of CsCCD1 and CsCCD4 in elder leaves were higher than those in younger leaves and stems. With the increase of turning over times, the expression levels of CsCCD1 and CsCCD4 decreased, while supplementary LED light strongly promoted their expression levels in the early stage. The expression level of NCED in younger leaves was higher than that in elder leaves and stems on average, and the expression trend varied in the process of turning over. NCED3 first increased and then decreased, with an expression level 15 times higher than that in fresh leaves. In the late stage of turning over, supplementary LED light significantly promoted its gene expression. In conclusion, CsCCD gene family member expressions were regulated by mechanical force and light. These understandings may help to optimize tea processing techniques and improve tea quality.
