Correlation of serum lipid profile and disease activity in patients with inflammatory bowel disease / 中华内科杂志

To analyze the correlation between lipid profile and disease activity in patients with inflammatory bowel disease (IBD).A total of 307 Crohn′s disease (CD) patients, 232 ulcerative colitis (UC) patients and 165 healthy subjects from the same geographic region were included. Total cholesterol (TC), triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C) and lipoprotein(a)[Lp(a)] were retrieved from their medical records. Crohn disease activity index (CDAI) and Mayo scores were calculated as measurement of disease severity for CD and UC separately. Patients with CD and UC had lower TC, TG, HDL-C and LDL-C levels than those in control group ( P<0.05). Additionally, CDAI was negatively associated with TC, HDL-C and LDL-C levels ( r=-0.218, -0.210, -0.176, P<0.05), while TG level was not associated with CDAI. Mayo scores was not significantly associated with TC, HDL-C, LDL-C and TG. Patients with CD had higher Lp(a) levels than those in UC and control group ( P<0.05). Furthermore, patients with active CD had higher Lp (a) levels than those with inactive disease ( P<0.05).The Lp(a) levels in CD patients were positively associated with CDAI ( r=0.151, P<0.05), while Lp(a) level in UC group was nor assocriated with Mayo score. Patients with IBD have dyslipidemia and lipid profile is associated with disease activity in CD patients.

The association between mesenteric fat hypertrophy and behavior and activity of Crohn′s disease / 中华内科杂志

Objective:Mesenteric fat hypertrophy is present in about a quarter of Crohn′s disease (CD) patients and it can be easily detected by bowel ultrasound (US). The purpose of this research was to assess the correlation between mesenteric fat hypertrophy and behavior and activity of CD.Methods:A total of 89 CD patients who admitted to the First Affiliated Hospital of Nanjing Medical University from August 2018 to November 2019 were recruited in this study. The total CD patients were divided into two groups depending on with or without mesenteric fat hypertrophy by US tests. Crohn′s disease activity index (CDAI), simplified endoscopic score for Crohn′s disease (SES-CD), serum inflammatory indicators and fecal calprotectin were assessed.Results:Mesenteric fat hypertrophy was significantly associated with stricturing behavior (B2, P<0.01). CDAI ( P=0.002) , blood platelet ( P=0.001) , C-reactive protein ( P=0.024) , fecal calprotectin ( P=0.004) and bowel wall thickness ( P<0.01) in patients with mesenteric fat hypertrophy were significantly higher than those without, but not the erythrocyte sedimentation rate ( P=0.110) and SES-CD ( P=0.115) . Serum albumin ( P=0.001) in patients with mesenteric fat hypertrophy was lower than that in patients without mesenteric fat hypertrophy. Conclusion:Mesenteric fat hypertrophy is correlated with intestinal stenosis and disease activity in patients with Crohn′s disease.

Effect of Edelfosine on the Proliferation of Hela Cells and Its Mechanism / 中国药房

OBJECTIVE:To investigate the effect of edelfosine on the proliferation of Hela cells and its mechanism.METHODS:Hela cells were treated with edelfosine at doses of 0(control),0.5,1.0,5.0,10.0 ?mol?L-1 for 96 h.MTT assay,flow cytometry,and staining were performed to determine the cell proliferation activity,cell cycle,and apoptotic rate.RESULTS:As compared with control,the cell proliferation activity of Hela cells was inhibited in a dose-and time-dependent manner after being treated by edelfosine for 24～96 h.After being treated by edelfosine(1.0,5.0,10.0 ?mol?L-1) for 72 h,the number of Hela cells significantly increased in G0/G1 phase but decreased in S phase(P
