Objective:To explore the risk factors, clinical features, endoscopic characteristics and the efficacy of antiviral therapy in ulcerative colitis (UC) patients complicated with cytomegaloviremia (CMV) and Epstein-Barr (EB) viremia.Methods:From April 1, 2014 to January 31, 2019, at The Second Hospital of Hebei Medical University, a total of 320 UC patients hospitalized at the Department of Gastroenterology were enrolled. According to the pathogens, the patients were divided into four groups: complicated with CMV and EB viremia group ( n=35), only complicated with CMV viremia group ( n=33), only complicated with EB viremia group ( n=52) and without CMV and EB viremia group ( n=200). Clinical features and the efficacy of antiviral therapy of the patients were retrospectively analyzed. Multivariate logistic regression was used to analyze the risk factors of UC complicated with CMV and EB viremia. Kruskal-Wallis H test, Chi-square test and Fisher exact test were used for statistical analysis. Results:The proportion of patients of age>60 years old (42.86%, 15/35), the rate of glucocorticoid use (51.43%, 18/35) within three months before onset and the inefficacy rate of glucocorticoid treatment (22.86%, 8/35) of UC complicated with CMV and EB viremia group were all higher than those of UC without CMV and EB viremia group (14.00%, 28/200; 24.50%, 49/200; 1.00%, 2/200), and the differences were statistically significant ( χ2=17.062, 10.598 and 29.769; all P<0.01). However, there were no statistically significant differences between UC complicated with CMV and EB viremia group and UC without CMV and EB viremia group in gender, and treatment of 5-aminosalicylic acid (5-ASA), azathioprine and infliximab within three months before onset (all P>0.05). The proportion of patients with fever (54.29%, 19/35), abdominal pain (91.43%, 32/35), hematochezia (94.29%, 33/35), weight loss (28.57%, 10/35), severe disease activity (94.29%, 33/35), total colon involvement (91.43%, 32/35), serum albumin less than 30 g/L (71.43%, 25/35) and hemoglobin less than 100 g/L (48.57%, 17/35) of UC complicated with CMV and EB viremia group were all higher than those of UC without CMV and EB viremia group (13.50%, 27/200; 43.00%, 86/200; 44.00%, 88/200; 13.50%, 27/200; 38.00%, 76/200; 65.00%, 130/200; 18.00%, 36/200 and 18.50%, 37/200), and the differences were statistically significant ( χ2=31.475, 27.945, 32.930, 5.100 and 40.194, Fisher exact test, χ2=44.242 and 15.220, all P<0.01). However, there were no statistically significantl differences in clinical classification and disease course (all P>0.05). The incidence rates of deep ulcer (45.71%, 16/35), irregular ulcer (42.86%, 15/35) and longitudinal ulcer (8.53%, 3/35) under endoscopy of UC complicated with CMV and EB viremia group were significantly higher than those of UC without CMV and EB viremia group (1.50%, 3/200; 3.50%, 7/200 and 1.00%, 2/200), and the differences were statistically significant ( χ2=72.521 and 49.837, Fisher exact test, all P<0.01). The incidence rates of deep ulcer and irregular ulcer under endoscopy of UC complicated with CMV and EB viremia group were higher than those of UC only complicated with EB viremia group (15.38%, 8/52 and 11.54%, 6/52), and the differences were statistically significant ( χ2=9.663 and 11.206, P=0.002 and 0.001). The results of Multivariate Logistic regression analysis showed that severe disease activity, serum albumin level less than 30 g/L, and deep ulcer and irregular ulcer under endoscopy were risk factors of UC patients complicated with CMV and EB viremia (odds ratio=48.519, 44.352, 53.432 and 39.989, 95% confidence interval 9.057 to 587.669, 4.499 to 437.245, 3.302 to 864.670 and 3.418 to 467.910, all P<0.05). The improvement rate of antiviral therapy in UC complicated with CMV and EB viremia group (73.53%, 25/34) was significantly lower than those of UC only complicated with CMV group (96.88%, 31/32) and UC only complicated EB viremia group (95.65%, 44/46), and the differences were statistically significant ( χ2=6.989 and 6.310, P=0.008 and 0.012). Conclusions:UC patients with severe disease activity, serum albumin level less than 30 g/L, and deep ulcer and irregular ulcer under endoscopy are more likely to develop CMV and EB viremia. The more severe the disease, the worse the treatment response, so it is necessary to strengthen the screening to CMV and EB virus infection in UC patients.

PEP06 is a novel endostatin-Arg-Gly-Asp-Arg-Gly-Asp(RGDRGD)30-amino-acid polypeptide featuring a terminally fused RGDRGD hexapeptide at the N terminus.The active endostatin fragment of PEPO6 directly targets tumor cells and exerts an antitumoral effect.However,little is known about the kinetics and degradation products of PEP06 in vitro or in vivo.In this study,we investigated the in vitro metabolic stability of PEP06 after it was incubated with living cells obtained from animals of different species;we further identified the degradation characteristics of its cleavage products.PEP06 underwent rapid enzymatic degradation in multiple types of living cells,and the liver,kidney,and blood play important roles in the metabolism and clearance of the peptides resulting from the molecular degradation of PEP06.We identified metabolites of PEP06 using full-scan mass spectrometry(MS)and tandem MS(MS2),wherein 43 metabolites were characterized and identified as the degradation metabolites from the parent peptide,formed by successive losses of amino acids.The metabolites were C and N terminal truncated products of PEP06.The structures of 11 metabolites(M6,M7,M16,M17,M21,M25,M33,M34,M39,M40,and M42)were further confirmed by comparing the retention times of similar full MS spectrum and MS2 spectrum information with reference standards for the synthesized metabolites.We have demonstrated the metabolic stability of PEP06 in vitro and identified a series of potentially bioactive downstream metabolites of PEP06,which can support further drug research.

Background::Gestational weight gain (GWG) is associated with the risk of gestational diabetes mellitus (GDM). However, the effect of weight gain in different trimesters on the risk of GDM is unclear. This study aimed to evaluate the effect of GWG on GDM during different trimesters.Methods::A birth cohort study was conducted from 2017 to 2020 in Shenzhen, China. In total, 51,205 participants were included comprising two models (early pregnancy model and middle pregnancy model). Gestational weight (kg) was measured at each prenatal clinical visit using a standardized weight scale. Logistic regression analysis was used to assess the risk of GDM. Interaction analysis and mediation effect analysis were performed in the middle pregnancy model.Results::In the early pregnancy model, the risk of GDM was 0.858 times lower (95% confidence interval [CI]: 0.786, 0.937) with insufficient GWG (iGWG) and 1.201 times higher (95% CI: 1.097, 1.316) with excessive GWG after adjustment. In the middle pregnancy model, the risk of GDM associated with iGWG increased 1.595 times (95% CI: 1.418, 1.794) after adjustment; for excessive GWG, no significant difference was found ( P = 0.223). Interaction analysis showed no interaction between GWG in early pregnancy (GWG-E) and GWG in middle pregnancy (GWG-M) ( F = 1.268; P = 0.280). The mediation effect analysis indicated that GWG-M plays a partial mediating role, with an effect proportion of 14.9%. Conclusions::eGWG-E and iGWG-M are associated with an increased risk of GDM. Strict control of weight gain in early pregnancy is needed, and sufficient nutrition should be provided in middle pregnancy.
